摘要： A method of beam failure recovery request (BFRQ) transmission is proposed. UE can search for UE-specific control channel in a search space that is signaled specifically for monitoring network response of the BFRQ. Furthermore, configurations indicated specifically for BFRQ can be carried by dedicated signaling such as high-layer radio resource control (RRC) signaling. After successfully rebuilding connection, UE assumes the demodulation reference signal (DMRS) ports of UE-specific control channel to be spatially quasi-co-located (QCL-ed) with the reference signals identified during the beam failure recovery procedure.

摘要： A method for harmonized operation between radio link monitor and beam failure recovery is proposed. In one example, upon indication of unsuccessful recovery from beam failure, a counter is initiated to count a configured number of OOS indication before RLF is declared due to beam failure. In another example, upon indication of successful recovery from beam failure, a counter is initiated to count a configured number of IS indication before starting over RLM procedure on its previous observations on failed beams. As a result, either early RLF declaration or RLM reset may be triggered based on BFR procedure to more accurately maintain the link quality.

摘要： A method of beam reciprocity state reporting and uplink beam management in wireless communication systems with beamforming is proposed. In one novel aspect, a UE determines its UE beam reciprocity state and sends a "UE beam reciprocity state" message to a BS, which triggers proper uplink beam management accordingly. The UE beam reciprocity state message can take place when UE tries to register to the network. For example, according to factory setting, UE reports at least "Positive" or "Negative" in this message. Beam reciprocity state can be updated by a "UE beam reciprocity state update" message. An auxiliary information can be transmitted to the BS for UL beam management if UE reports "Negative" for beam reciprocity state. The auxiliary information indicates the uncertainty level of UE beams.

摘要： A flexible radio frame structure for both FDD and TDD is proposed. Under the flexible frame structure, each radio frame consists of a plurality of slots, and each slot within a radio frame has a flexible slot type. As a basic scheduling unit, each slot can be configured by the base station via physical layer signaling. The slot type can be changed dynamically based on current system needs to support different DL/UL ratios and latency requirements. With the support of different slot types and asynchronous DL/UL HARQ operation, HARQ operation for DL/UL can share the same HARQ timing to simplify the system design and reduce implementation complexity.

摘要： A flexible time-frequency grid is proposed. A baseline OFDM format consisting of CP and a following symbol interval is scaled in time to generate a set of extended OFDM frame formats. The set of extended OFDM frame formats is further extended by scaling in bandwidth. The OFDM frame formats and the extended OFDM frame format set are used dynamically in the wireless communication system in accordance to the changes of the communication environment. Furthermore, various methods are proposed to avoid and/or combat performance degradation of the resource elements (REs) interfered by non-orthogonal REs in the neighborhood due to different OFDM symbol configurations in the flexible time-frequency grid.

摘要： A network control device includes a wireless communications module and a controller. The wireless communications module uses a preferred transmitting beam to communicate with a communications apparatus in one or more downlink opportunities corresponding to the preferred transmitting beam. The controller schedules signal or data to be transmitted in at least one downlink opportunity corresponding to the preferred transmitting beam. When scheduling signal or data to be transmitted, the controller further provides at least one training gap, in which the controller does not schedule any dedicated data to the communications apparatus, in the downlink opportunity corresponding to the preferred transmitting beam.
