Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

Abstract: Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.

Abstract: Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a base station to transmit a measurement configuration for measuring interference (e.g., cross link interference (CLI)). The measurement configuration may include a measurement direction configuration for measuring the interference. Additionally or alternatively, the UE may select a measurement direction configuration for measuring interference based on the measurement configuration. The UE may measure interference based on the measurement configuration. The UE may transmit a measurement report to the base station. The measurement report may include an indication of the selected measurement direction configuration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a unicast channel for a first downlink transmission from a base station using a first semi-persistent scheduling (SPS) configuration. The UE may receive downlink control information (DCI) from the base station indicating a second SPS configuration associated with a different coverage level than the first SPS configuration. In some cases, the DCI may be DCI that is common to a set of UEs. Here, the DCI may indicate the second SPS configuration and the UE may identify a set of parameters associated with the second SPS configuration based on a radio resource control (RRC) message received prior to the DCI. Based on receiving the indication of the second SPS configuration, the UE may monitor the unicast channel for a second downlink transmission from the base station using the second SPS configuration.

Abstract: Aspects are provided which improve LBT by associating contention windows with transmission burst lengths and by allowing contention windows and maximum burst lengths to be adjusted based on interference activity. For downlink, a UE receives a PG for a downlink transmission from a base station indicating a CCA length based on a contention window size associated at least with a burst length for the downlink transmission. The UE performs, after receiving the pre-grant, a CCA based on the CCA length, transmits an APG to the base station when the CCA is successful, and receives the downlink transmission in response to the APG. For uplink, the base station performs a CCA based on a contention window associated at least with a burst length for an uplink transmission, transmits an uplink grant to the UE when the CCA is successful, and receives the uplink transmission in response to the uplink grant.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Methods, systems, and devices for wireless communications are described. A device such as a user equipment (UE) or a base station may identify a beam switching capability of the UE, the beam switching capability indicating a threshold quantity of beam switches during a transmission time interval, a threshold quantity of symbol periods between beam switching operations, or a combination thereof. The device may determine that the beam switching capability of the UE is satisfied based at least in part on one or more parameters (e.g., one or more symbol period durations, one or more quantities of beam switches during a transmission time interval, one or more adjustment parameters, one or more threshold values associated with the capability of the UE, etc.). The device may perform one or more beam switching operations based on determining that the beam switching capability is satisfied.
