Abstract: Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once. Collisions may be resolved by dropping or rescheduling overlapping information from the lower priority transmission(s) or channel(s) in consideration of the higher priority transmission(s) or channel(s), or by multiplexing or piggybacking overlapping information from a first priority transmission(s) or channel(s) with a second priority transmission(s) or channel(s).

Abstract: Methods, systems, and devices for wireless communications are described that support configuration of aperiodic sounding reference signal transmission and triggering. A base station may transmit, within a first transmission time interval (TTI), a grant triggering a user equipment (UE) to transmit an aperiodic sounding reference signal (A-SRS), and may identify offset information indicating a TTI offset relative to the grant. The base station may determine a second TTI for the A-SRS based on the TTI offset. A UE may detect, within a first TTI, the grant triggering the UE to transmit the A-SRS, identify the offset information indicating the TTI offset relative to the grant, and determine the second TTI for transmitting the A-SRS based on the TTI offset. The UE may transmit the A-SRS in an SRS resource of the second TTI, and the base station may monitor the SRS resource of the second TTI for the A-SRS.

Abstract: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

Abstract: Certain aspects of the present disclosure relate to reporting difference in timing between cells using multiple connectivity in a wireless network. A first connection served by at least a first cell and a second connection served by at least a second cell to facilitate communicating with at least the first cell and at least the second cell are established. A reporting configuration specifying one or more parameters related to reporting a timing difference between cells is received. A timing difference between at least the first cell and at least the second cell is determined, and the timing difference is reported to at least the first cell over the first connection or to at least the second cell over the second connection. This can facilitate scheduling time aligned operations over the first and second cells, or related cell groups, in multiple connectivity.

Abstract: Methods, systems, and devices for wireless communications are described for determination of sounding reference signal (SRS) parameters when multiple SRS resource sets are configured for a same SRS transmission resource. A user equipment (UE) may select one SRS resource set for a SRS transmission based on a prioritization of different SRS resource sets. In some cases, different SRS resource sets may be associated with different SRS usage parameters that indicate a use case for the SRS, and the UE may transmit a joint SRS for two or more SRS resource sets for predetermined combinations of SRS usage parameters. A base station that receives the SRS transmission may measure one or more channel parameters of the SRS and determine one or more settings for subsequent communications with the UE.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.

Abstract: Wireless communications systems and methods related to improve control reporting latency are provided. A wireless communication device receives, from a first link in a first time interval, first control information associated with a second link and the first time interval. The wireless communication device transmits, via the second link in the first time interval, a control report associated with the second link based on a report configuration that is independent from the first control information. The report configuration is associated with a waveform type. The wireless communication device receives, from the first link in a second time interval following the first time interval, second control information that is dependent on the control report. The report configuration includes a power headroom (PHR) report configuration. The PHR report configuration includes a reference PHR report configuration. The PHR report configuration includes a delayed PHR report configuration.
