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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station associated with a cell of a time division duplex communication system may determine a guard interval that is less than a maximum time delay, based at least in part on a radius of the cell, for air-to-ground communications; and transmit a scheduling configuration to a user equipment that identifies the guard interval. 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, first signaling that includes one or more time division duplexing (TDD) patterns associated with a neighboring cell. The UE may receive second signaling that includes a slot format indicator (SFI) associated with the neighboring cell. The UE may determine a slot configuration allocating transmission time intervals (TTIs) in the neighboring cell to one or more of downlink communication or uplink communication based at least in part on the one or more TDD patterns associated with the neighboring cell and the SFI associated with the neighboring cell. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a sub-band specific sounding reference signal (SRS) resource indicator identifying subsets of SRS resources, of a set of SRS resources, associated with precoding a physical uplink shared channel (PUSCH) communication that is to be transmitted in a PUSCH resource. The user equipment may precode the PUSCH communication based at least in part on the sub-band specific SRS resource indicator. The user equipment may transmit the PUSCH communication after precoding the PUSCH communication based at least in part on the sub-band specific SRS resource indicator. 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 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.

Abstract: Aspects described herein relate to receiving a configuration indicating multiple association rules associating random access preambles and payload formats, selecting, as part of a random access procedure, a random access preamble from the random access preambles for transmitting over a random access occasion, determining, based at least in part on at least one of the association rules in the configuration, a payload format associated with the random access preamble and a corresponding payload resource unit, and transmitting the random access preamble over the random access occasion and, according to the payload format, an associated payload over the corresponding payload resource unit. Multiplexing of payload resource units with same or different payload formats can be performed in time, frequency and code domains, based on the received configuration.
