Abstract: A UE and a base station are disclosed. The UE may receive, from a base station, an indication of a configuration of an SS and a set of candidate DL-RSs associated with a plurality of CG-SDT resources. The base station may monitor for the EIL data transmission from the LIE corresponding to a CG-SDT occasion of the CG-SDT resources. The UE may measure a RSRP of each of the set of candidate DL-RSs associated with the CG-SDT resources. The UE may select an UL beam based on the measured RSRP of each of the set of candidate DL-RSs associated with the CG-SDT resources. The UE may transmit, to the base station via the selected UL beam, the UL data transmission over a CG-SDT occasion of the plurality of CG-SDT resources. The UE may monitor the SS for a response to the UL data transmission from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may retransmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: The present disclosure relates to methods and devices for wireless communication at an apparatus, e.g., a UE or a base station. The base station may be configured to configure one or more RACH resources for a FD RACH configuration and transmit, to at least one UE, an indication of the one or more RACH resources configured for the FD RACH configuration. The UE may be configured to receive the indication of the FD RACH configuration for the one or more RACH resources. The UE may further be configured to select, based on the received indication, at least one RACH resource of the one or more RACH resources for the FD RACH configuration and transmit, to the first base station via the selected at least one RACH resource, at least one message of a RACH procedure based on the FD RACH configuration.

Abstract: Wireless communication techniques that include multi-beam techniques for small data transfer (SDT) over preconfigured uplink resources (PURs) are discussed. A UE may receive an indication of at least one PUR allocated for uplink communication when the UE does not have a RRC connection with a base station. The at least one PUR may include one or more distinct PUR occasions. The UE may also receive an indication of one or more distinct SSBs associated with the one or more distinct PUR occasions. Each PUR occasion of the one or more distinct PUR occasions may be associated with only one SSB of the one or more distinct SSBs. The UE may also transmit information to the base station during a PUR occasion associated with an SSB that is associated with a RSRP that is greater than a threshold. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described to differentiate random access response types, such that a user equipment (UE) may identify a random access response for the UE. A UE may transmit a random access message that may be associated with a first type of random access response. The base station may be configured to communicate different types of random access responses, and may configure a random access response and an associated downlink control signal to correspond to the first type of random access response. The base station may transmit the downlink control signal to the UE by configuring different demodulation reference signals, different group identifiers, different search spaces or control resource sets, or different downlink control information. The UE may determine that the random access response is of the first type and may receive the random access response based on the decoded downlink control signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

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.
