Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may perform an initial random access channel (RACH) attempt by transmitting, to a base station, an initial request message of an initial two-step RACH procedure; and perform an additional RACH attempt, using an alternative two-step RACH procedure, based at least in part on determining that an initial response message, corresponding to the initial request message, of the two-step RACH procedure is not received during an initial random access response window. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. 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 may determine a message type for a random access message associated with a two-step random access channel procedure. The message type may be either a first message type or a second message type that is different from the second message type. The message type may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The user equipment may transmit the random access message based at least in part on the determined message type. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify, during a connected mode or an idle mode of a user equipment, a set of synchronization signal block communications, wherein the set of synchronization signal block communications includes two or more synchronization signal block communications; and transmit, to a user equipment, the set of synchronization signal block communications using spatial multiplexing, wherein the set of synchronization signal block communications are each transmitted concurrently using different spatial resources associated with beam sweeping transmission. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a wireless device. The method generally includes selecting multiple transmission reception points (TRPs) of a plurality of TRPs to form a group of TRPs based on information indicative of relative positions between a user equipment (UE) and each of the plurality of TRPs such that the relative positions between the UE and the multiple TRPs satisfy a criteria. The multiple TRPs of the group of TRPs are selected such that levels of communication delay between each of the multiple TRPs and the UE are within a defined delay range. The method further includes communicating on an uplink using a single timing advance between the UE and the group of TRPs.

Abstract: Certain aspects of the present disclosure provide techniques for feedback compression. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving, from a base station, a configuration to be used for compressing one or more measurements corresponding to at least one reference signal using an artificial intelligence (AI) encoder; receiving the at least one reference signal; and transmitting a codeword to the base station, the codeword being associated with a compression of the one or more measurements in accordance with the configuration.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically scheduling antenna resources of a wireless node, such as, antenna panels of a user equipment (UE). In some cases, a first node (e.g., a UE) performs, with two or more other nodes, a first beam sweep procedure across two or more antenna resources of the first node on two or more wireless interfaces, generates or obtains scheduling information based on results of the first beam sweep procedure, wherein the scheduling information indicates which of the antenna resources is scheduled for which wireless interfaces, and communicates with the other nodes on the wireless interfaces according to the scheduling information.

Abstract: A user equipment (UE) may receive an indication associated with receiving downlink control information (DCI) communications. The indication may identify a first physical downlink control channel (PDCCH) monitoring location associated with receiving DCI communications during a first period of time, and a second PDCCH monitoring location associated with receiving DCI communications during a second period of time that follows the first period of time. The UE may monitor in the first PDCCH monitoring location and the second PDCCH monitoring location based at least in part on the indication.
