Abstract: A method of wireless communication by a sidelink user equipment (UE) includes selecting a sidelink wakeup signal (WUS) resource from a dedicated sidelink WUS resource pool. The sidelink WUS resource pool differs from a sidelink data transmission resource pool. The method also includes transmitting, to a receiver, a WUS on the selected sidelink WUS resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message of a two-stage set of DCI. The UE may receive, from the base station, a second DCI message of the two-stage set of DCI. The UE may select between the first DCI message and the second DCI message as a timing reference point. In some examples, the UE may receive, from the base station, downlink data on the physical downlink channel. In some examples, the UE may transmit, to the base station, an uplink data message on the physical uplink channel.

Abstract: A method of wireless communication performed by a user equipment (UE) includes receiving, from a base station (BS) in a first fixed frame period (FFP), downlink communication information (DCI), where the DCI indicates a scheduled DL communication in a second FFP subsequent to the first FFP. The method also includes monitoring for a downlink (DL) signal in the second FFP. The method also includes transmitting, based on the monitoring for the DL signal, an acknowledgement/non-acknowledgement (ACK/NACK) indicating whether the scheduled DL communication was detected.

IPC: H04B7/14

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may receive a first control channel associated with a multiple relay based communication. The node may identify a target node of a payload of the first control channel based at least in part on at least one of: information included in the payload, or an identifier associated with the first control channel. The node may transmit a second control channel carrying the payload toward the target node if the node is not the target node. The node may decode the payload, if the node is the target node. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive control signaling configuring at least a first UE operation mode and a second UE operation mode. The UE may transmit one or more uplink messages to a base station in the unlicensed radio frequency spectrum band using a first set of parameters according to the first UE operation mode. In some examples, the UE may receive a control message comprising an indication that the UE is to switch from communicating according to the first configured UE operation mode to communicating according to the second configured UE operation mode. The UE may then transmit, in response to the received indication, one or more uplink messages to the base station in the unlicensed radio frequency spectrum band using a second set of parameters according to the second UE operation mode.

Abstract: Wireless communications systems and methods related to routing communications in a multiple-relay environment are provided. A base station (BS) transmits, to one or more wireless communication devices, a reference signal configuration indicating one or more reference signal resources. The base station receives, from a first wireless communication device of the one or more wireless communication devices, a channel state report based on one or more reference signals in the one or more reference signal resources. The channel state report includes channel measurement information for one or more links, each link connecting a wireless communication device of the one or more wireless communication devices to a user equipment (UE). The BS transmits, to the UE via a second wireless communication device of the one or more wireless communication devices based on the channel state report, a data signal.

Abstract: Apparatus, methods, and computer-readable media for transmission of downlink feedback information using downlink control information format 0_2 are disclosed herein. A user equipment (UE) may receive, from a base station on a first subband, a downlink control information (DCI) having a first predetermined DCI format or a second predetermined DCI format, in which the second predetermined DCI format has a length smaller than the first predetermined DCI format. The UE also may determine that the DCI indicates a downlink feedback information (DFI) based on one or more of an indication in the DCI or a first predetermined scrambling code associated with the DCI, when the DCI is received with the second predetermined DCI format

IPC: H04W76/14

Abstract: Aspects relate to sharing a channel occupancy time (COT) initiated by a network access node (e.g., a base station) with one or more wireless communication devices for sidelink communication between the wireless communication devices. In this example, the network access node can transmit a COT structure indication (COT-SI) to the wireless communication device (s) indicating the COT resources (e.g., time and frequency resources) of the COT that may be shared with sidelink. In some examples, the wireless communication device can receive a message from the network access node including a COT sharing indicator indicating whether COT sidelink sharing is enabled or disabled.

IPC: H04W72/10

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit a sidelink message in accordance with one or more parameters associated with a priority of the sidelink message. The UE may determine a channel access priority class (CAPC) associated with the sidelink message based on the priority of the sidelink message. The UE may perform a listen-before-talk (LBT) procedure in accordance with the CAPC to gain access to a wireless channel for a channel occupancy time (COT). The UE may select a set of starting positions relative to the COT based on the priority, the CAPC, or both. The UE may transmit the sidelink message within the COT based on a starting position of the set of starting positions and the LBT procedure. The UE may perform a quantity of one or more retransmissions of the sidelink message based on the CAPC.

Abstract: Method and apparatus for PHR for multi-PUSCH repetitions. The apparatus selects a first PUSCH to carry a first MAC-CE having a first PHR (1902). The apparatus determines a first value of the first PHR based on a third PUSCH (1904). The apparatus selects a second PUSCH to carry a second MAC-CE having a second PHR based on the third PUSCH or the first PUSCH (1906). The apparatus determines a second value of the second PHR based on a fourth PUSCH (1908).
