摘要： Aspects are provided which allow a first wireless device such as a UE or base station to prioritize beams which are simultaneously received from or transmitted to cells of different numerologies or which are asynchronous to each other. The device determines an overlap in time between a first signal from a first cell and a second signal from a second cell, where the second cell includes at least one of a different numerology than the first cell or an asynchronous timing relative to the first cell. The device applies a beam prioritization rule for selecting a beam associated with the first signal or the second signal carrying information in separate beams. The device transmits information to or receives information from a second wireless device based on the selected beam. Thus, simultaneous beam conflict resolution may be improved for cells having different numerologies or asynchronous timing.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (HE) may support beam management to determine beams for communicating with a base station, measure characteristics of the beams, and periodically report the measurements to the base station. The beam management may include a beam failure recovery procedure, where the UE detects and resolves a beam failure with the base station. Additionally, the UE may perform radio link monitoring (RLM) on a set of reference signals configured by the base station to determine if a radio link (e.g, beamformed transmission) is synchronized or not between the UE and base station. In some cases, these RLM reference signals (RLM-RSs) may be reconfigured, where the reconfiguration may be based on the periodic beam measurement reports for beam management, a beam monitoring event trigger, a beam failure recovery, or a combination thereof.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of parameters associated with a temporary bandwidth part (BWP) switch from a first BWP to a second BWP. The parameters may include a time duration for the temporary BWP switching procedure, a network antenna configuration for the second BWP, transmission parameters for communications scheduled in the second BWP, or a combination thereof. The UE may switch from the first BWP to the second BWP in accordance with the temporary BWP switching procedure and communicate with a network entity using the indicated parameters. For example, the UE may receive one or more downlink messages or transmit one or more uplink messages in accordance with the indicated parameters. Thereafter, the UE may switch from the second BWP to a third BWP in accordance with the temporary BWP switching procedure.

摘要： This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates to the UE to apply demodulation reference signal (DMRS) bundling to physical uplink shared channel (PUSCH) transmissions. The UE may maintain phase coherence across multiple PUSCH transmissions, to which the DMRS bundling is applied, to enable joint channel estimation across the multiple PUSCH transmissions. The UE may transmit, based at least in part on the configuration, uplink control information (UCI) that includes a coherence indication. The UE may multiplex the UCI with a PUSCH transmission of the multiple PUSCH transmissions to which the DMRS bundling is applied. The coherence indication may indicate whether the PUSCH transmission is coherent with one or more other PUSCH transmissions, of the multiple PUSCH transmissions, transmitted by the UE. Numerous other aspects are described.
