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.

Abstract: A UE initiates a PUSCH transmission determination procedure if at least one of a first PUSCH overlaps with a second PUSCH in a transmission and a first PUCCH overlaps with the first PUSCH or the second PUSCH, or if the first PUCCH overlaps with at least one of the first PUSCH or the second PUSCH in the transmission and the first PUSCH and the second PUSCH are not overlapped with each other, the first PUSCH and the second PUSCH being associated with different uplink priorities. The UE multiplexes the first PUCCH with the first PUSCH or the second PUSCH that overlaps with the first PUCCH. The UE transmits the first PUSCH or the second PUSCH based on at least one of the uplink priorities associated with the first PUSCH and the second PUSCH or uplink priorities associated with the first PUCCH and a second PUCCH.

Abstract: Apparatus, methods, and computer program products for beam updating are provided. An example method includes receiving DCI. The method further includes determining, based on the DCI, whether the DCI is associated with a beam update for uplink, downlink, or a combination of the uplink and the downlink. The method further includes determining, from the DCI, a TCI state that indicates a beam for the uplink, the downlink, or the combination of the uplink and the downlink.

Abstract: Certain aspects of the present disclosure provide a method of wireless communications, including: multiplexing a first uplink control information (UCI) and a second UCI on a physical uplink control channel (PUCCH), wherein the first UCI has a first priority and the second UCI has a second priority, wherein the first priority is higher in priority than the second priority, computing a transmit power based on one or more power control parameters associated with the first UCI, and transmitting the PUCCH in accordance with the transmit power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a first UCI bit multiplexed with a second UCI bit, the first UCI bit having a first sequence applied and the second UCI bit having a second sequence, that is orthogonal to the first sequence, applied. The UE may transmit the UCI message. Numerous other aspects are described.

The one or more RS resources may be associated with an index modulation technique including a plurality of UL or DL information bits. The UE may transmit, to the base station, or receive, from the base station, the plurality of UL or DL information bits. The plurality of UL or DL information bits may include at least one of one or more first bits or one or more second bits. At least one of the one or more RS resources may be selected based on at least one of the one or more first bits or the one or more second bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a collision between one or more hybrid automatic repeat request (HARQ) acknowledgment (ACK) resources and one or more scheduling request (SR) resources having different priorities. The UE may perform an action associated with at least one of the one or more HARQ ACK resources or the one or more SR resources, wherein the action is based at least in part on at least one of: a physical uplink control channel (PUCCH) format or a priority associated with a HARQ ACK resource, or a PUCCH format or a priority associated with an SR resource. Numerous other aspects are provided.
