Abstract: Wireless communications systems and methods related to bandwidth part (BWP) hopping for interference mitigation are provided. A user equipment (UE) receives, from a base station (BS), a bandwidth part (BWP) configuration indicating a first BWP hopping pattern in a plurality of frequency subbands within a shared radio frequency band. The UE monitors for a first communication signal in a first frequency subband of the plurality of frequency subbands. The UE performs BWP hopping from the first frequency subband to a second frequency subband of the plurality of frequency subbands based on the first BWP hopping pattern. The UE monitors, after performing the BWP hopping, for a second communication signal in the second frequency subband.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for determining sidelink channel metrics using reference signal measurements of reference signals transmitted by other UEs. A first UE may receive a control message from a base station, and the control message may indicate a measurement threshold. The first UE may generate a reference signal measurement of a reference signal transmitted by a second UE via a sidelink channel between the first UE and the second UE. The UE may transmit a measurement report to the base station based at least in part on the measurement satisfying the threshold. The report may be a quantized value of the measurement or a bit indicating that the measurement satisfies the threshold. Based on receipt of the measurement report, the base station may determine to transmit data to the second UE via a transmission to the first UE.

Abstract: A base station may configure a set of autonomous uplink (AUL) resources for a specific base station receive beam, or the AUL resources may be configured for specific user equipment (UEs) or user groups. Additionally, the AUL resources may be configured to include a sensing portion, a data portion, or both. As an example, a UE may receive an AUL configuration that includes an indication of a set of AUL resources that are specific to a base station receive beam. The UE may then determine that the set of AUL resources is available and perform an AUL transmission of uplink data using the set of beam-specific AUL resources. Additionally or alternatively, the UE may perform the AUL transmission with respective portions that include a sensing signal and the uplink data. The base station may use the sensing signal to determine a receive beam on which to receive the uplink data.

Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

Abstract: Methods, systems, and devices for wireless communications are described that support listen before talk (LBT) for uplink transmissions using multiple subbands. A base station may support communication with a user equipment (UE) via multiple subbands and may transmit an uplink grant to the UE that allocates resources of the multiple subbands for transmission of a shared data channel by the UE. The base station may include an indication within the uplink grant that indicates to the UE to perform a given type of LBT for each subband. After transmitting the uplink grant, the base station may transmit control information or other signaling (e.g., channel occupancy time system information (COT-SI)) that indicates subbands on which the UE is to perform a given type of LBT or other subbands on which the UE is to perform a different type of LBT.

Abstract: Wireless communications systems and methods related to communications in a network that supports usage of configured grant uplink control information (CG-UCI) data are provided. A user equipment (UE) may receive a configuration for a configured grant resource and transmit an UL communication signal in the configured grant resource. The UL communication signal may include a CG-UCI multiplexed with UL data. Additionally, the CG-UCI may indicate whether the UL data includes additional UCI.

Abstract: Wireless communications systems and methods related to communications in a network are provided. A user equipment (UE) may generate during a first time period, an uplink (UL) communication signal based on a scheduled grant or a configured UL grant. The UE may detect a downlink (DL) communication from a base station (BS) during a second time period after the first time period. The DL communication is devoid of the scheduled grant and the configured UL grant. The UE may transmit to the BS, the UL communication signal based on the scheduled grant or the configured UL grant in response to detecting the DL communication.

Abstract: Wireless communications systems and methods related to performing listen-before-talk (LBT) with discovery signal transmissions for spectrum sharing are provided. A wireless communication device senses a channel in a spatial domain based on a plurality of expected beam transmission directions, wherein the wireless communication device is associated with a first network operating entity, and wherein the channel is shared by a plurality of network operating entities including the first network operating entity. The wireless communication device transmits a plurality of discovery signals in one or more of the plurality of expected beam transmission directions during a discovery period to facilitate synchronization in the channel based on the sensing.

Abstract: A transmission opportunity (TO) allows a transmitting device, such as a base station to transmit up to a pre-determined TO duration. For new radio (NR), subcarrier spacing (SCS) is no longer fixed. This may limit a TO duration for a UE to a small portion of the allowed TO duration, for new radio (NR), a transport block (TB) takes up one slot. A method, apparatus, and computer-readable medium are disclosed extend a TB over more than one slot to maximize utilization of a TO duration, for improved resource utilization and service quality. A method, apparatus, and computer-readable medium implemented by a communication device are disclosed to receive a signaling message, to configure a flexible transport block (TB) to extend the TB over more than one slot. Then the communication device may receive a portion of the flexible TB, based on the received signaling message.
