摘要： Wireless communication capabilities are disclosed that support determination of timing advance for a physical uplink control channel (PUCCH) in joint acknowledgement feedback mode of a network having multiple timing advance groups (TAGs) configured per serving cell and multiple control resource set (CORESET) pool index values configured per bandwidth part (BWP). In a first aspect, a method of such capabilities includes receiving a configuration message including at least a feedback mode configuration configuring a joint acknowledgement feedback mode, a TAG configuration for each serving cell, and any CORESET pool indices for the BWPs of the serving cells. A user equipment (UE) receives downlink transmissions and determines a timing advance for a PUCCH with a joint acknowledgement message using the last downlink control information (DCI) message received scheduling the downlink transmissions. Alternatively, a UE may use a predetermined timing advance. Other aspects and features are also claimed and described.

摘要： Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.

摘要： Methods, systems, and devices for wireless communications are described. The method includes receiving a configuration message indicating a group common control resource allocated to a set of UEs that includes the UE, identifying a hashing function assigned to the UE for detecting control messaging communicated via the group common control resource that is addressed to the UE, receiving, via the group common control resource, a control message indicating addressing data and a bitmap, and processing the addressing data using the hashing function and the bitmap to determine applicability of the control message to the UE.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first tracking reference signal configuration and a second tracking reference signal configuration. The first tracking reference signal configuration may include a first set of parameters and the second tracking reference signal configuration may include a second set of parameters. The UE, the base station, or both may identify an indicator for selection from among the first tracking reference signal configuration and the second tracking reference signal configuration. The UE may receive, from the base station and based on the identified indicator for selection, a tracking reference signal in accordance with the first tracking reference signal configuration or the second tracking reference signal configuration.

摘要： Certain aspects of the present disclosure provide enhancements to enable per transmission reception point (per-TRP or per beam group)-based beam failure recovery, and more particularly, techniques for TRP-specific beam failure recovery request (BFRQ). A method that may be performed by a user equipment (UE) includes communicating using beams associated with at least two beam groups, each associate with one of the TRPs, detecting a beam failure in a first one of the beam groups, and transmitting an indication of a BFRQ specific to a beam group in which the beam failure was detected.
