Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a shared radio frequency spectrum band for a transmission opportunity. The UE may perform an autonomous uplink transmission over the shared radio frequency spectrum band during a first portion of the transmission opportunity. The UE may transmit a physical layer scheduling request comprising a transmission size parameter for a second portion of the transmission opportunity. The UE may receive an uplink grant for the second portion of the transmission opportunity based at least in part on the scheduling request. The UE may perform a scheduled uplink transmission over the shared radio frequency spectrum band during the second portion of the transmission opportunity according to the uplink grant.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support sidelink transmission resource aggregation for in-coverage new radio sidelink (NR SL) operations. In a first aspect, a method of wireless communication includes obtaining a sidelink aggregation factor identifying a number of sidelink resource slots available to a user equipment (UE) to add to each sidelink resource slot allocated in a grant of sidelink channel access from a serving base station. The UE may then receive a sidelink transmission grant identifying at least one granted sidelink resource slot, and determine an aggregated set of sidelink resource slots for each granted sidelink resource slot. The UE may then transmit sidelink communications using the aggregated set of sidelink resource slots for each granted sidelink resource slots used for the sidelink communications. Other aspects and features are also claimed and described.

Abstract: Subcarrier spacing (SCS) for data may be adapted or dynamically configured based on the occurrence or presence of a synchronization signal block (SSB) transmission. For example, during a SSB transmission, the SCS of data may be automatically switched from some default data SCS to a second SCS (e.g., the SCS of the SSB) to allow for frequency division multiplexing (FDM) of data and SSB where the data and SSB use the same numerology. As such, communicating devices (e.g., a base station and a user equipment (UE)) may identify some location or configuration for a SSB, and may determine a second subcarrier spacing (e.g., a subcarrier spacing associated with the SSB) such that the SCS of data may be adapted to the second subcarrier spacing during the FDM of the SSB and the data. The SSB and data may thus be contemporaneously transmitted or received using the second SCS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request (HARQ) process identifier set associated with a first configured scheduling process and may determine a second HARQ process identifier set associated with a second configured scheduling process. The UE may assign an HARQ process identifier, included in the first HARQ process identifier set, to a process instance associated with the first configured scheduling process and may assign an HARQ process identifier, included in the second HARQ process identifier set, to a process instance associated with the second configured scheduling process. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support enhanced methods for indicating random access transmission beams. For example, a user equipment (UE) may transmit a set of uplink reference signals to a base station, each uplink reference signal corresponding to a respective uplink beam. The base station may receive the uplink reference signals and may determine signal qualities for the uplink beams. The base station may identify one or more uplink beams for the UE to use in subsequent random access procedures and may transmit control signaling to the UE indicating one or more beams for random access procedure transmissions. The UE may transmit random access messages to the base station using an uplink beam selected based on the control signaling received from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink message that includes a control channel monitoring periodicity and control channel offset for a radio frame. A UE may identify a set of slots within a radio frame to monitor for downlink control information (DCI) based on the received downlink message. The UE may identify a control channel candidate within a search space of each slot of the set of slots, and may identify the control channel candidate of a first slot based on calculations that include a current slot and a previous slot. There may be one or more slots that occur between the previous slot and the current slot. The UE may receive DCI that is user-specific based on the identified control channel candidate.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station in a wireless communications system using downlink beams and uplink beams. A UE may determine whether to maintain or change an uplink beam of the UE after a downlink beam failure. The UE may receive control signaling indicating a configuration for uplink beam management for use in response to a downlink beam failure detection in a deployment configuration where uplink beams of the UE may be decoupled from downlink beams of the UE. The UE may perform a downlink beam failure recovery (BFR) procedure based on a downlink beam failure of a downlink beam of the UE. The UE may reconfigure an uplink beam based on the configuration and the downlink BFR procedure.

Abstract: Wireless communications systems and methods related to autonomous sidelink communication are provided. A first user equipment (UE) communicates, in a first subband of a plurality of subbands within a shared radio frequency band during a first time period, first sidelink control information (SCI) associated with a second subband of the plurality of subbands. The first UE communicates, with the second UE, first sidelink data in the second subband during the first time period based on the first SCI. The first UE communicates, with the second UE in the first subband during a second time period, second SCI associated with a third subband of the plurality of subbands, the third subband being different from the second subband based on a frequency hopping pattern. The first UE communicates, with the second UE, second sidelink data in the third subband during the second time period based on the second SCI.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support management of network-configured sensing bandwidths in a wireless communication system. In particular aspects, a network configures a sensing bandwidth, and the sensing bandwidth configuration is signaled to a contending node. The contending node (e.g., a UE or a base station) performs a medium sensing procedure (e.g., a listen-before-talk (LBT) procedure) using the signaled configuration of the sensing bandwidth. Aspects of this disclosure provide various techniques for signaling the configuration of the sensing bandwidth to the contending node.

Abstract: Methods, systems, and devices for wireless communications are described for receiver-assisted channel access in shared radio frequency spectrum. A receiver, such as a user equipment (UE) may transmit a measurement report to a transmitter, such as an access network entity, that indicates channel occupancy as measured at the receiver. In some cases, the receiver may identify resources for signal measurement and reporting that are configured by the transmitter, and provide an interference measurement report based on the signal measurements. The interference measurement report may indicate whether a channel is occupied, or an occupancy level of the channel. Resources may be configured for multiple beams, with the interference measurement report including interference measurements for the multiple beams. Further, the signal resources may provide resources for a listen-before-talk (LBT) procedure, through signal resource sets that span multiple slots.
