Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: This disclosure provides systems, methods and apparatus for multi-beam operation at a user equipment (UE). In some aspects, a user equipment (UE) may transmit a beam report indicating a number of simultaneous transmit beams supported by the UE. The UE may receive a common beam indication for multiple TCI states. The UE may select at least one TCI state as an uplink component for a common beam and may communicate with a base station (BS) using the common beam. The UE may receive control signaling enabling a group-based beam reporting mode at the UE and an indication to apply a group-based beam reporting configuration for uplink beam reporting. The UE may selectively enable or disable the group-based beam reporting configuration. The UE may report multiple reference signal resource indices for multiple reference signals. The UE may transmit the reference signals using multiple spatial domain transmit filters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an increased bandwidth configuration for an enhanced physical uplink control channel (ePUCCH) based at least in part on an ePUCCH format of the ePUCCH, wherein the increased bandwidth configuration uses a plurality of contiguous resource blocks (RBs) for the ePUCCH; and transmit the ePUCCH using the increased bandwidth configuration. Numerous other aspects are provided.

Abstract: A method of wireless communication may include transmitting an uplink slot with a first control region, a second control region, and (e.g., optionally) a data region. Each region may include time resources and frequency resources. Transmitting the uplink slot may include transmitting the first control region in an earlier part of the uplink slot and transmitting the second control region (e.g., and the data region) in a later part of the uplink slot. The first control region may include time-critical control information and the second control region may include non-time-critical control information. A receiver receiving the uplink slot may receive the first control region before receiving the data region and the second control region.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a periodic resource grant, the configuration indicating a set of parameters for the periodic resource grant. The UE may receive a dynamic indication of a modification to one or more of the set of parameters. The UE may receive one or more communications via the periodic resource grant based at least in part on the modification. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.

In some aspects, receiving, from a base station, one or more configurations for a physical random access channel (PRACH) communication, and transmitting a PRACH communication according to a configuration selected from the one or more configurations based at least in part on the PRACH communication being subject to a maximum permissible exposure (MPE) condition and a rule. The rule may include a parameter that is received from the base station. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication or follow rules to determine whether to enter or skip a measurement gap. The measurement gap may be a scheduled gap in data communications in order for the UE to measure one or more reference signals. The UE may enter or skip the measurement gap based at least in part on the determination. Numerous other aspects are provided.

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).
