Abstract: Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines (e.g., based on an indication from base station) one or more physical random access channel (PRACH) preamble transmission parameters associated with one or more PRACH coverage enhancement (CE) levels of a RACH procedure. The UE and the base station perform a RACH procedure in accordance with the one or more PRACH preamble transmission parameters.

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 transmit 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: In an embodiment, a node (e.g., a UE, BS or relay node) transmits a paging message including at least one reference value associated with an event. At least one UE responds to the paging message (e.g., based on the presence of the at least one reference value in the paging message) with a response including UE-identifying information and the at least one reference value associated with the event. In an example where the node is a relay node, the relay node may coordinate with a BS so as to obtain an allocation of paging resources for transmission of the paging message. In a further embodiment, a UE may transmit, to a BS, at least one Message-A comprised by a PUSCH of a 2-Step RACH procedure, wherein the Message-A includes the at least one reference value associated with the event.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits a DSS capability indication to a network entity (e.g., base station), which determines scheduling information for resources of a DSS carrier based on the DSS capability indication. In another aspect, a BS transmits RAT-specific (e.g., LTE-specific) information associated with a DL RS (e.g., LTE CRS) to a UE, which processes the DL RS on a DSS carrier based at least in part on the RAT-specific information.

Abstract: In an aspect of the disclosure, a first method, a first computer-readable medium, and a first apparatus are provided. The first apparatus may be a UE. The first apparatus may generate a payload of a first preamble message associated with a first RACH procedure, and the payload may indicate a first priority of the first RACH procedure that is relatively higher than a second priority of a second RACH procedure. The first apparatus may send the first preamble message including a RACH preamble and the payload to a base station, and the first preamble message may indicate an identifier (ID) of the first apparatus.

Abstract: A configuration for multiple UEs having the same RA-RNTI to generate RA-RNTI for RACH procedures. The apparatus transmits a random access message. The apparatus receives a RAR during a RAR window in response to the random access message. The RAR window spanning at least two system frames. The apparatus determines one or more RA-RNTIs. Each RA-RNTI may be based, at least in part, on a random access channel occasion and type of random access procedure. The apparatus decodes the RAR based on the one or more RA-RNTIs.

Abstract: A user equipment (UE) may be configured to generate a preamble of a first message associated with a random access channel (RACH) procedure, such as a two-step RACH procedure. The UE may be further configured to determine an identifier (ID) associated with the UE based on at least one of an ID associated with the preamble or a port index associated with a demodulation reference signal (DMRS). The UE may generate a payload of the first message that indicates the ID associated with the UE. The UE may then transmit the first message to a base station to initiate the RACH procedure. Potentially, the UE may receive a second message from the base station responsive to the first message, and the second message may confirm the ID associated with the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant-small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. Numerous other aspects are provided.

Abstract: A wireless device can flexibly switch between different frequency-division duplexing (FDD) modes including one or more half-duplex (HD) FDD modes and a full-duplex (FD) FDD mode in wireless communication. The wireless device can intelligently switch between the FDD modes to meeting different requirements of power consumption, traffic latency, and/or coverage enhancement.
