Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect beam failure for a first beam group in a cell including the first beam group and a second beam group. The UE may selectively transmit a beam failure recovery request for the first beam group based at least in part on a determination of uplink resource availability in the second beam group. Numerous other aspects are described.

Abstract: In an aspect, a user equipment (UE) transmits, to a base station, an uplink (UL) power change capability indication. The base station receives the UL power change capability indication, and transmits, to the UE, scheduling information for one or more UL transmissions that include one or more UL power changes based on the UL power change capability indication.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining when to apply downlink control information (DCI)-based updates. A method that may be performed by a user equipment (UE) includes receiving a downlink control information (DCI) indicating an update to be applied to at least one of an uplink (UL) transmission or a downlink (DL) transmission, determining an application time for applying the update based, at least in part, on a slot where an acknowledgement (ACK) was transmitted, and applying the update in accordance with the determined application time.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining when to apply downlink control information (DCI) based updates using cross-component carrier (cross-CC) scheduling. A method that may be performed by a user equipment (UE) includes receiving, on a first component carrier (CC), a DCI indicating an update to be applied to at least one of an uplink (UL) transmission or a downlink (DL) transmission, determining an application time for applying the update based, at least in part, on a parameter associated with one or more second CCs, and applying the update in accordance with the determined application time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a set of beam indications, associated with a set of beam indication types, for a set of beams to use for communication via a set of channels. The set of beam indications includes a first beam indication, associated with a first beam indication type, that indicates to use a first beam for communication via at least a first channel of the set of channels. The base station may select, based at least in part on the set of beam indication types, a second beam indication type for transmission of a second beam indication that indicates to use a second beam for communication via the first channel of the set of channels. The base station may transmit the second beam indication using the second beam indication type. Numerous other aspects are described.

Abstract: A method of wireless communication performed at a user equipment (UE) includes receiving, at the UE, a set of downlink (DL) reference signals (RSs) associated with one or more first transmission beams. The method also includes measuring, at the UE, the set of DL-RSs. The method further includes performing, at the UE, an uplink transmission having a transmission power that is set by a pathloss estimation function based on a set of pathloss parameters. One or more of pathloss parameters of the set of pathloss parameters is based on measuring the set of DL-RSs.

Abstract: A base station may transmit one or more reference signals to a user equipment (UE) to measure. However, the base station is typically limited to configuring one downlink reference signal per antenna panel of the UE. This can reduce network efficiency because the base station has to switch downlink reference signals in order to switch antenna panels. Techniques and apparatuses described herein allow a UE to transmit a report that includes a plurality of measurements of a downlink reference signal corresponding to a plurality of antenna panels and/or to transmit a report that includes one or more measurements of a plurality of downlink reference signals from an antenna panel. The base station may therefore map a downlink reference signal to a plurality of antenna panels of the UE. Accordingly, the base station is able to switch antenna panels without switching downlink reference signals.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for power control in FD systems based on a PL-RS for measuring self-interference. In aspects, a base station may configure a PL-RS for one or more beam pairs and schedule a DL transmission including the PL-RS. A UE may measure self-interference corresponding to the one or more beam pairs based on the PL-RS and adjust an UL Tx power for a FD operation based on the self-interference measured for the one or more beam pairs. The UE may subsequently transmit an UL transmission for the FD operation based on the adjustment to the UL Tx power, such that the base station may receive an UL transmission having an UL Tx power that is based on the measured self-interference associated with the PL-RS.

Abstract: A method of wireless communication receives multiple beams from a base station. The method also simultaneously reports a signal to interference plus noise ratio (SINR) for multiple beams with a single channel measurement resource (CMR) and a single interference measurement resource (IMR). The single IMR is configured for multiple interference sources. A method of wireless communication by a base station configures a UE with a group of interference sources. The base station also configures the UE with an interference measurement resource associated with the group of interference sources.

Abstract: A method of wireless communication by a base station detects a UE is in a high speed train scenario. The method also instructs the UE to enter a high speed train (HST) mode when the UE is detected to be in the high speed train scenario. The method further performs beam management in accordance with the HST mode. A UE (user equipment) for wireless communication detects when the UE is in high speed train scenario. The UE also reports the high speed train scenario to a base station and then receives instructions from the base station to enter a high speed train (HST) mode. The UE performs beam management in accordance with the HST mode.
