摘要： Aspects of the disclosure can provide an apparatus and method for cell reselection in a New Radio (NR) system. In some examples, the apparatus includes transceiver and processing circuitry. The processing circuitry ranks a priority list of frequencies which correspond to a plurality of cells, wherein the cells are part of a NR system. The plurality of cells can include a current serving cell, one or more inter-frequency cells, and one or more intra-frequency cells. The processing circuitry measures reference signal received power (RSRP) and/or reference signal received quality (RSRQ) of the cells in the priority list of frequencies in an unused synchronization signal block (SSB) time location in a discontinuous reception (DRX) cycle. Further, the processing circuitry can select a new serving cell when the measured signal performance of the new serving cell satisfies a cell selection criteria.

摘要： NCSG can be believed as a type ofMG. UE's measurement scheduling for the NCSG frequency will be the same as frequency measured within gap. NW will firstly configure the legacy measurement gap. When UE reports the supported NCSG bands, NW can configure the NCSG pattern for NCSG frequency layers' measurements. The frequency layers with NCSG can be monitoring within gap. When NCSG gap is fully overlapping with MG, the frequencies with NCSG shall be measured within NCSG gap. When NCSG gap is fully overlapping with MG, the frequencies with NCSG shall be measured within legacy measurement gap. When NCSG gap is partially overlapping with MG, the frequencies with NCSG will be measured within the NCSG gap occasions which is not overlapping with MG occasions. Alternatively, the frequency layers' measurements with NCSG can be believed as a measurements without gap. Inter-frequency measurement with NCSG which is partially overlapping or fully non-overlapping with measurement gap will share the searcher with intra-frequency measurements in SCC. Due to no searcher limitation, E-UTRA inter-RAT measurements with NCSG can be measured at the same time with SCC's intra-frequency measurements.

摘要： This invention proposes a mechanism of processing SRS antenna switching in a wireless communication network. The method could include a SRS antenna switching impact table/signaling for each band combination which will check whether the configured SRS transmission for antenna switching will impact other carriers in other bands. The method also includes a scheduling searching to check whether SSB receiving in other band (s) happen at the same time. The method will decide how many slots UE will interrupt for each carriers DL/UL based on a searching table or UE's capability signaling or real decision system based on the numerology of victim carrier (s) and aggressor carrier.

摘要： When a UE supports both Uu link (WAN) and NR V2X sidelink, a RRC reconfiguration command can initiate or cease the V2X sidelink communication. An interruption to Uu link (WAN) will happen during RRC reconfiguration. When a UE supports both LTE V2X sidelink and NR V2X sidelink, there is an interruption to LTE V2X sidelink due to NR V2X sidelink synchronization source change. Also, there is an interruption to NR V2X sidelink due to LTE V2X sidelink synchronization source change. When a UE supports Uu link (WAN), LTE V2X sidelink and NR V2X sidelink, there is an interruption to Uu link due to switching between NR SL and LTE SL. When a UE supports at least NR V2X sidelink and two synchronization sources that UE switches between are not synchronized, for broadcast communication, the sidelink communication will be interrupted with 1ms due to synchronization sources change. For group-cast and unicast communication, the sidelink communication will be ceased due to synchronization source change. When a UE supports both Uu link (WAN) and NR V2X sidelink, the sidelink communication will be interrupted with 1ms due to synchronization sources change between eNB/gNB and gNB/eNB. The interruption will happen after UE Uu link receiving the handover command on the old PDSCH and before UE sending the new PRACH.

摘要： When there is no active serving cell on this FR2 band and all SCells to-be-activated belongs to the same intra-band, the SCell activation can be defined as known and unknown condition. If all of the multiple SCell activation can be unknown SCells and if single MAC CE command for these multiple SCells, only one unknown SCell needs to execute cell search and L1-RSRP measurement. Other unknown SCells just hold on the activation procedure until one of the unknown SCell finishing the cell search and L1-RSRP measurement. After that all unknown SCells will wait their TCI configuration from network and execute their SCell activation process independently. It shall be noted that although the TCI configuration for QCL TypeD RS shall be the same source SSB, the TCI configuration for these unknown SCells shall still be different because each serving cell's timing/Doppler configuration RS bases on its serving cell's information independently. If at least one of the multiple SCell activation can be known SCell and one of the multiple SCell activation can be unknown SCell and if single MAC CE command for these multiple SCells, the unknown SCell won' t need these cell search, L1-RSRP measurement and reporting procedure. Unknown SCells will wait PDCCH TCI, PDSCH TCI, CSI-RS reporting configuration and SCell activation command. After that, the Unknown SCells will also have the same activation procedure as known SCell. Owing to the TCI and CSI-RS configuration for each SCell may not come at the same time. The RF retuning occasion for each SCell shall also different, but as we discussed above, UE can schedule the RF retuning occasion to avoid the collision with SSB for timing tracking. Thus, no additional interruption is needed in this scenario. When SCells to-be-activated belongs to the inter-band, UE shall be allowed to use different Rx/Tx beams on 2 CCs at a time. Multiple SCell activation shall be sequential. It means L1-RSRP measurement and reporting procedure shall be extended for each inter-band FR2 SCells.

摘要： The configured spatial relation can be QCLed to the source of DL RS, such as SSB or CSI-RS, where the terminology 'QCLed' means associated to in the document below. In this QCLed relation, the active spatial relation switching shall differentiate known and unknown situation. In known condition, when UE receives the spatial relation switching configuration, the UE shall parse this configuration and execute the fine timing tracking on the new configured QCLed RS. After that, the UE shall switch its spatial relation to the new configuration. In unknown condition, besides the above procedure, the UE shall also execute the L1-RSRP measurement after UE parse the spatial relation configuration and before the fine timing tracking. The configured spatial relation can be QCLed to the root source of UL SRS. In this QCLed relation, the active spatial relation switching don' t need to differentiate known and unknown situation. When UE receives the spatial relation switching configuration, the UE shall parse this configuration and switch the spatial relation followed with the configured SRS index. This spatial relation switching shall apply for PUSCH, PUCCH, and SRS. In PUCCH, the MAC based spatial relation switch shall be defined. In PUSCH, spatial relation activation shall only follow the related PUCCH or SRS spatial relation switch procedure. In periodic SRS, the RRC based spatial relation switch shall be defined. In semi-persistent SRS, the MAC based spatial relation switch shall be defined. In aperiodic SRS, the DCI based spatial relation switch shall be defined. The aperiodic SRS should always associate with a known spatial relation.

摘要： Currently, in legacy LTE, the UE will choose PCell (RRC_CONNECTD) or the serving cell (RRC_IDLE) as synchronous reference when V2X sidelink communication is out of coverage on the concerned frequency. In NR, considering the EN-DC, NE-DC OR NR-DC deployment, it's not necessary for the UE to always choose PCell as the synchronous reference. One option is UE will always choose gNB as the synchronous reference. When both PCell and PSCell are gNBs, UE could choose PCell as the synchronous reference. Another option is UE will choose PCell or PSCell based on their RSRP values. The third option is that the network can signal a RSRP threshold. When PCell and PSCell's RSRP will be higher than this threshold, the UE will at first choose gNB as synchronous reference because gNB can give better timing to UE. In other case, the UE can choose synchronous reference based on PCell and PSCell's RSRP value.

摘要： This invention proposes a mechanism of SCell activation in a wireless communication network. The mechanism is used for an mmWave Scell activation scenario. When the SCell to be activated is the first SCell in mmWave, the processing could include Scell identification, L1-RSRP beam management, L1-RSRP beam reporting, CSI reporting process in UE side. The processing also include SCell activation command trigger, beam selection and TCI and spatial relation indication in network side. The UE could use beam management to find the N best beams and report the beam index to the network. The network could indicate the TCI state and spatial relation for the reporting CSI and SRS based on the beam reporting by UE. Alternatively, the method could include this SCell measurement reporting with beam index in deactivated state, and Scell identification, CSI reporting process in UE side. The processing also include SCell activation command trigger, beam selection and TCI and spatial relation indication in network side. The UE could use deactivated SCell's measurement to report the beam index to the network. The network could indicate the TCI state and spatial relation for the reporting CSI and SRS based on the deactivated SCell's measurement reporting by UE. When the SCell to be activated is not the first SCell in mmWave, the SCell's CSI reporting TCI state and SRS spatial relation could rely on exist PCell/PSCell or any activated serving cell. The processing could include Scell identification, CSI reporting process in UE after SCell activation command triggered in network.
