摘要： Methods and systems for detecting an enhanced massive mobile broadband (eMBB) physical downlink control channel (PDCCH) in the presence of for ultra-reliable low latency communication (URLLC) users are disclosed. A eMBB wireless transmit/receive unit (WTRU) may receive a eMBB control resource set (CORESET) configuration for a CORESET including a PDCCH preemption indicator. If PDCCH preemption is enabled based on the PDCCH preemption indicator, the eMBB WTRU may identify and remove preempted resource element groups (REGs) in the eMBB CORESET by comparing channel estimates for each REG bundle in the eMBB CORESET. The WTRU may perform channel estimation based on remaining REGs in the eMBB CORESET and detect the PDCCH by performing blind decoding, based on a received signal, on the remaining REGs in the eMBB CORESET.

摘要： A method and apparatus for selecting or reselecting a home Node-B (HNB), (i.e., a closed subscriber group (CSG) cell), among cells having colliding physical layer signals are disclosed. Once the identity (ID) of an HNB is determined, measurements needed to support cell selection or reselection are performed. A broadcast channel that broadcasts an HNB ID is detected and synchronized to, and information obtained from the broadcast channel is forwarded to a non-access stratum (NAS). The broadcasted HNB ID is checked against an HNB white-list provided by the NAS to determine whether the HNB is suitable for a wireless transmit/receive unit (WTRU). The WTRU selects the HNB to camp on, or changes from a cell currently serving the WTRU to the HNB if it is determined to be more suitable than the current serving cell.

摘要： Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing
and de-multiplexing and the use of common and VE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence oflegacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.

摘要： Channel state information is reported in periodic and aperiodic reports for multiple component carriers or serving cells. Channel state information may be reported for a subset of aggregated downlink carriers or serving cells. For an aperiodic report, the carrier(s)/serving cell(s) for which channel state information is reported are determined based on the request for the aperiodic report. When a CQI/PMI/RI report and a HARQ ACK/NACK report coincide in a subframe, the HARQ ACK/NACK report is transmitted on PUCCH, and the CQI/PMI/RI report is transmitted on PUSCH.

摘要： A wireless transmit/receive unit (WTRU) receives a downlink transmission from an eNodeB including a plurality of spatial layers transmitted to a plurality of WTRUs paired for multiuser MIMO. The WTRU decodes the downlink transmission based on a corresponding WTRU-specific reference signal. WTRU-specific reference signals are multiplexed using a frequency and code division multiplexing. WTRU-specific reference signals for different subgroup of antenna ports are multiplexed onto different subcarriers in a frequency domain and the WTRU-specific reference signals of the same sub-group of antennas ports are multiplied by an orthogonal cover code. The resource elements used for the WTRU-specific reference signals on antenna ports in one subgroup may be muted on antenna ports in another subgroup. A WTRU may transmit the uplink demodulation reference signal without precoding. The number of resource blocks allocated for the demodulation reference signal may be greater than the number of resource blocks allocated for the payload.

摘要： Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePD -CCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type sub frame definition may also be provided and/or used for support of such a reduced bandwidth.

摘要： A wireless transmit receive unit (WTRU) may send a grant free transmission comprising a first and a second part, each of which may be associated with a priority. The first part's priority may be higher than the second part's priority. The WTRU may select a first back of value from a first range of back off values. The WTRU may determine whether the grant free transmission was successful. If the grant free transmission was not successful, the WTRU may send a retransmission of the grant free transmission, which may include the first part and may not include the second part. The retransmission may select a second back off value from a second range of back off values, which may be a larger than the first range of back off values. The second back off value may indicate the number of grant free resource to skip prior to sending the retransmission.
