Abstract: A network can switch between different network power modes to control power consumption and/or performance A user equipment (UE) can be configured to perform uplink channel repetitions across different power modes of the network. In one aspect, the UE can transmit the uplink channel repetitions using different configurations across different power modes. In one aspect, the UE can drop the remaining uplink channel repetitions after switching power mode. In one aspect, the UE can change the number of uplink channel repetitions after switching power mode. In one aspect, the UE can change the redundancy version of the uplink channel repetitions after switching power mode.

Abstract: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.

Abstract: Methods, systems, and devices for wireless communications are described for systems that use resource bandwidths within one or more bandwidth parts (BWPs). Such resource bandwidths may be configured in one or more BWPs to support relatively fast switching and allow enhanced flexibility for communications within a BWP. Within one or more BWPs, downlink reference signal resources of a first resource bandwidth may be associated with one or multiple uplink resources of a second resource bandwidth, and precoding for uplink communications in the one or multiple uplink resources may be calculated based on the associated downlink reference signal resources. Additionally or alternatively, abeam used for uplink communications may be provided to the UE in transmission control information (TCI). Further, in some cases, multiple disjoint subsets of uplink frequency resources within a resource bandwidth may use different beams, according to an indication provided in TCI.

Abstract: Methods, systems, and devices for wireless communications are described for configuration and transmission of one or more uplink reference signals for tracking. A user equipment (UE) may transmit one or more uplink reference signals for tracking and a base station or transmission-reception point (TRP) may estimate one or more frequency or time shifts (e.g., a Doppler shift, time shift, or both) associated with communications with the UE. The estimated frequency shifts, time shifts, or combinations thereof, may be used to provide compensated communications (e.g., Doppler compensated communications) with the UE. The uplink reference signal for tracking may be a sounding reference signal that is configured as a tracking reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a configuration that indicates to use a first type of precoding or a second type of precoding, for an uplink communication, based at least in part on one or more frequency resources for a downlink communication. The UE may perform a transmission of the uplink communication, having the first type of precoding or the second type of precoding, in accordance with the configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first reference signal from a first transmission reception point (TRP) and a second reference signal from a second TRP. The UE may estimate a first Doppler shift associated with the first TRP based on receiving the first reference signal and may estimate a second Doppler shift associated with the second TRP based on receiving the second reference signal. In some cases, the UE may receive a first Doppler pre-compensated downlink transmission from the first TRP and a second Doppler pre-compensated downlink transmission from the second TRP based on a Doppler pre-compensation indication that indicates whether the downlink transmissions are Doppler pre-compensated.

Abstract: Methods and devices for wireless communications are described in which one or more bandwidth parts (BWPs) may be configured with a set of resource bandwidths that are used form communications between a user equipment, UE, and a base station. The UE may be configured with an active BWP and an active resource bandwidth that does not contain any random access occasions and, as part of a random access procedure, the UE may switch to an initial resource bandwidth within a BWP for transmission of the random access request, where the initial resource bandwidth is configured with one or more random access occasions. A medium access control (MAC) entity at the UE may perform the resource bandwidth switching for the random access procedure.

Abstract: The apparatus may be configured to transmit a configuration of a first set of common resources for a SRS for cross-link interference measurement, the first set of common resources being common to a first plurality of UEs. The apparatus may further be configured to receive, from a second UE in the first plurality of UEs, a report of the cross-link interference associated with a first UE in the first plurality of UEs and measured via a first resource in the first set of common resources. In some aspects, another apparatus may be configured to receive, from a base station, a configuration indicating a set of common resources for a SRS for cross-link interference measurement between UEs. The apparatus may further be configured to transmit a first SRS in a first resource in the set of common resources.
