Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to switch from a first transmission configuration indicator (TCI) state associated with a first cell to a second TCI state associated with a second cell. The UE may apply the second TCI state, including switching from a first bandwidth part (BWP) associated with the first cell to a second BWP associated with the second cell. For example, the UE may receive an indication to switch from the first BWP to the second BWP. Additionally, or alternatively, the UE may determine to switch from the first BWP to the second BWP based at least in part on the indication to switch from the first TCI state to the second TCI state. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for finite field parity for a hybrid automatic repeat request (HARQ) codebook. A method that may be performed by a base station (BS) includes indicating, to a user equipment (UE), a codebook for uplink transmission of HARQ feedback, the codebook based on: (i) a number (M) of candidate downlink transmission occasions for a time period, and (ii) a maximum number (k) of downlink transmissions the UE can receive during the time period. The method also includes selecting an action to perform based on a set of codepoints of the codebook, the set of codepoints comprising: (i) a first combination of codepoints, and (ii) a second combination of codepoints different from the first combination, wherein HARQ feedback calculated from the first combination is equal to HARQ feedback calculated from the second combination.

Abstract: Aspects relate to mechanisms for wireless communication devices to environmental sensing with the assistance of a network. A UE transmits an increase transmission power request message to a base station. The UE receives an increase transmission power acceptance message from the base station in response to transmitting the increase transmission power request message. The UE transmits a transmission using an increased transmission power for reflection by at least one object based on the increase transmission power acceptance message. The UE receives a reflection of the transmission reflected off the at least one object. The UE determines at least one parameter associated with the object based on the reflection of the transmission reflected off the at least one object.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station, a synchronization signal block (SSB) based at least in part on a determination that the SSB is included in a timing advance group (TAG) that includes a first subset of SSBs of a first set of SSBs associated with the first base station and a second subset of SSBs of a second set of SSBs associated with a second base station. The UE may communicate with the first base station based at least in part on the SSB. Numerous other aspects are described.

Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.

Abstract: Certain aspects of the present disclosure provide techniques for a configurable mode for a response to random access message. A method that may be performed by a user equipment (UE) includes receiving an indication from a base station (BS) that the BS operates according to a first mode in which the BS unicasts a RACH response during a two-step RACH procedure or a second mode in which the BS multicasts the RACH response. The RACH response includes a PDCCH and PDSCH. The UE sends a RACH message to the BS comprising a preamble and payload. The UE monitors and decodes the PDCCH of the RACH response based on the indicated first mode or second mode. The UE decodes the PDSCH of the RACH response and sends feedback to the BS based on the indicated first mode or second mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying configurations associated with respective uplink carriers for a random access channel (RACH) message, wherein a configuration associated with a first uplink carrier, of the respective uplink carriers, is different than a configuration associated with a second uplink carrier of the respective uplink carriers. The UE may select a set of uplink carriers, of the respective uplink carriers, on which to transmit the RACH message based at least in part on the configuration information. The UE may transmit the RACH message on the selected set of uplink carriers in accordance with the configuration information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.
