Abstract: The present disclosure generally relates to a methods, apparatus, and computer readable medium for implementing the methods for transmitting multi-bit SR (SRs) from a user equipment (UE). The UE receive from a base station a radio resource control (RRC) message from the base station. The RRC message may indicate that uplink component carriers (CCs) of the UE are to be assigned to a plurality of uplink CC groups. Upon receipt of the RRC, the UE may assign the uplink CCs to the plurality of uplink CC groups. A multi-bit SR may be generated for each group of the plurality of uplink CC groups. The UE may transmit the multi-bit SR generated for each group of the plurality of uplink CC groups to the base station. multi-bit SR transmission across different CCs may reduce latency in uplink grant and improve data transmission time.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, wireless devices operating in an unlicensed radio frequency spectrum band may perform directional listen-before-talk (LBT) procedures to gain access to a channel. In a beam-shrinking scheme for directional LBT, a wireless device may start an LBT procedure using a first beam (e.g., a wide beam). If the clear channel assessment (CCA) fails for the first beam (e.g., due to directional interference), the device may switch the LBT procedure to a second beam (e.g., a narrower beam). Depending on the direction of the interference source, the second beam may result in a successful LBT procedure. In a beam sweeping scheme for directional LBT, a wireless device may perform concurrent LBT over multiple narrow beams. If any beam of the set of beams detects frequent or continuous interference, the device may drop that beam from the concurrent LBT procedure.

Abstract: Techniques are described for wireless communication. A first method may include receiving at a user equipment (UE) over an unlicensed radio frequency spectrum band an indication of a time window associated with a transmission of a synchronization signal, and monitoring the unlicensed radio frequency spectrum band during the time window to receive a synchronization signal from a base station. A second method may include transmitting an indication of a time window associated with a transmission of a synchronization signal; performing a plurality of clear channel assessments (CCAs) on an unlicensed radio frequency spectrum band during the time window; and transmitting the synchronization signal over the unlicensed radio frequency spectrum band at a transmission time during the time window. The transmission time may be based at least in part on a result of at least one of the CCAs.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting sounding reference signals (SRS) with (e.g., before or after) a random access channel (RACH) acknowledgement (ACK) (e.g., after Msg4). An example method by a user equipment (UE) includes receiving a first downlink RACH message, receiving a second downlink RACH message after the first downlink RACH message, receiving signaling that indicates the UE is to transmit SRS after the second downlink RACH message, and transmitting the SRS after the second downlink RACH message, in accordance with the indication.

Abstract: Certain aspects of the present disclosure provide techniques for direct transport block (TB) forwarding in relaying operations. A method that may be performed by a relay node includes receiving, from a source node, an indication to directly forward a TB to a destination node, wherein directly forwarding includes transmitting the TB to the destination node through only a Physical (PHY) layer and a hybrid automatic repeat request (HARM) portion of a Media Access Control (MAC) layer in a protocol stack of the relay node and directly forwarding the TB to the destination node based, at least in part, on the indication.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on a priority value in a network (e.g., an Integrated Access and Backhaul (IAB) network). Certain aspects provide a method for wireless communications. The method generally includes determining, at a first wireless node, a priority value associated with the first wireless node configured to serve one or more child nodes, determining occurrence of interference to communications of the first wireless node and/or a second wireless node, and taking one or more actions in response to the determination of the interference based on the priority value.

Abstract: Certain aspects of the present disclosure provide techniques for reporting of a beam correspondence state. Certain aspects provide a method for wireless communication by a first wireless device. The method includes, based on detecting the occurrence of a triggering event, determining one or more beam correspondence states for one or more beams or portions of beams used by the first wireless device for communication. The method further includes transmitting one or more indications of the one or more beam correspondence states to a second wireless device, wherein the one or more indications of the one or more beam correspondence states indicate whether the first wireless device has the capability of beam correspondence between the one or more beams and corresponding one or more transmit or receive beams used by the first wireless device for communication.

Abstract: Aspects of the present disclosure provide techniques for handover in an Integrated Access and Backhaul (IAB) network or other type of network. One example method which may be performed by a source base station (BS) includes: determining to migrate a child node from a first logical IAB-distributed unit (DU) of an IAB-node to a second logical IAB-DU of the IAB-node, wherein the first logical IAB-DU is associated with the source BS, and wherein the second logical IAB-DU is associated with a target BS; sending, to the target BS, context information of the child node served by the first logical IAB-DU in response to the determination; and indicating, to the target BS, a traffic mapping configuration at the IAB-node associated with the context information and a backhaul connection of the IAB-node.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a first random access message to a serving cell. The UE receives a second random access message from the serving cell, in response to the first random access message. The UE transmits a third random access message to one or more transmission reception points of the serving cell in a beam sweep pattern for reception on multiple beams and using resources based on at least one of a beam pool index or a TRP index.
