    IPC: H04W74/08

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for selecting a PRACH occasion (RO) based on downlink quality, access congestion, latency (e.g., time to next available RO), beam correspondence, random access in previous transmissions, or combinations of these factors. The user equipment (UE) may detect access congestion of synchronization signal blocks (SSBs) and select the less congested SSB in the RO selection. The UE may detect the access congestion by receiving a back-off indicator from the base station, detecting a contention resolution failure, or the number or media access control (MAC) subheaders in a random access response. In some cases, the ROs associated with different SSBs have different latencies and the UE may select the earliest available RO.

    IPC: H04W16/28

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a set of reference signals to a first wireless node; receive information identifying a transmit power capability of the first wireless node based at least in part on transmitting the set of reference signals; and configure one or more transmission parameters for a first link with the first wireless node or a second link with a second wireless node based at least in part on the transmit power capability of the first wireless node. Numerous other aspects are provided.

    Abstract: A connection establishment procedure such as a handover or re-establishment procedure including a 2-step random access procedure may be completed within a defined time period. The defined time period may be measured from a handover command or a determination that a user equipment (UE) has lost a connection to a base station. The defined period of time may depend on one or both of a synchronization signal block (SSB) to random access channel (RACH) association period or a SSB to RACH association pattern period. The UE may receive a handover command from a serving cell. The UE may perform a handover in response to receiving the handover command or a re-establishment procedure in response to detecting the lost connection within the defined time period. One or more base stations may reserve resources for the connection establishment procedure during the defined time period.

    Abstract: Methods, systems, and devices for wireless communications are described for initiating beam training in systems that use beamformed wireless communications. A user equipment (UE) and a base station may establish communications using a first beam, and the UE may determine that a signal quality of the first beam is lower than a threshold value and that a beam training procedure is to be initiated. The UE may transmit a beam training request to initiate the beam training procedure, which may be transmitted as part of a bit sequence that is used to transmit uplink control information to the base station, such as with acknowledgment/negative-acknowledgment feedback, a scheduling request, or other uplink control information.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for a two-step random access channel (RACH) procedure, wherein the configuration information identifies a plurality of physical uplink shared channel (PUSCH) configurations for a PUSCH of the two-step RACH procedure; and transmit the PUSCH in accordance with a PUSCH configuration, of the plurality of PUSCH configurations, wherein the PUSCH configuration is selected based at least in part on a size of a payload of the PUSCH, and wherein a preamble of the PUSCH is used to indicate the selected PUSCH configuration. Numerous other aspects are provided.

    IPC: H04W72/12 ,  H04L5/16

    Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.
