Abstract: A proxy sensing-based channel access procedure is discussed for shared spectrum networks. Within a given network, a distribution of proxy nodes may be deployed around a network operating area. A control node, which controls the proxy sensing mode for the network, may configure the active network nodes to conduct communications via the shared communication spectrum without first performing any type of channel sensing on the shared communication spectrum. The control node may then also configured the proxy nodes to perform channel sensing on the shared spectrum for the entire network. Using the reported channel sense results from the proxy nodes, the control node may determine whether detected interference is occasional or persistent, and whether to take some action to modify the communications or operations of the network.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for propagation delay compensation (PDC). In some systems, a network entity and a group of user equipment (UEs) may support a group-based PDC procedure according to which the network entity may provide group-based PDC information to the group of UEs. In some aspects, a UE may participate in such a group-based PDC procedure in accordance with a clock accuracy constraint of the UE and depending on whether other UEs are likely to have similar PDC information. The network entity may assign an identifier (ID) to the group of UEs and scramble a message including the group-based PDC information using the ID. As such. UEs of the group of UEs may decode the message using the ID and adjust a timing of communications with the network entity using the group-based PDC information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, when operating in a multiple link communication system, one or more downlink control information (DCI) messages scheduling one or more downlink communications. The user equipment may determine, based at least in part on the one or more DCI messages, whether a communication constraint is satisfied for the one or more downlink communications. The user equipment may determine a communication configuration for the one or more downlink communications based at least in part on whether the communication constraint is satisfied. The user equipment may receive, in the multiple link communication system, the one or more downlink communications based at least in part on the communication configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a downlink control message scheduling multiple downlink transmission repetitions of multiple transport blocks (TBs), the downlink control message indicating a specified transmission configuration indicator (TCI) state for receiving the multiple downlink transmission repetitions according to the scheduling, the multiple downlink transmission repetitions including a first set of downlink transmission repetitions and a second set of downlink transmission repetitions. The UE may be configured to receive, via a default TCI state different from the specified TCI state, a first subset of downlink transmission repetitions from the first set of downlink transmission repetitions, the second set of downlink transmission repetitions, or both, based on a first time interval between a receipt of the downlink control message and a receipt of at least one downlink transmission repetition failing to satisfy a time duration.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may perform a channel access procedure to gain access to a bandwidth part in a shared spectrum for sidelink communications with a second UE. The first UE may transmit a signal to the second UE using one or more sub-bands of the bandwidth part, and the signal may include one or more sidelink synchronization signal blocks (S-SSBs) multiplexed with frequency resources associated with a physical sidelink shared channel (PSSCH). The one or more S-SSBs may be transmitted using a set of symbol periods of a transmission time interval (TTI) (e.g., a slot) that are preceded by a least four initial symbol periods of the TTI. In some examples, the first UE may transmit a sidelink control information (SCI) message indicating which of the one or more sub-bands include the one or more S-SSBs.

Abstract: Methods, systems, and devices for wireless communications are described. A device may precode a phase tracking reference signal (PTRS) sequence by applying a single discrete Fourier transform (DFT) to the PTRS sequence. The device may map the DFT precoded PTRS sequence to a subset of resources of a set of resources, and may transmit a signal carrying the DFT precoded PTRS sequence. Additionally or alternatively, the device may receive a signal that includes a DFT precoded PTRS sequence, demap the DFT precoded PTRS sequence to a subset of resources of a set of resources, decode the DFT precoded PTRS by applying a single inverse DFT (IDFT) to the DFT precoded PTRS sequence, estimate a phase error based on the decoding, and apply a phase error correction to a set of additional symbols associated with the signal based on the estimated phase error.

Abstract: Wireless communication capabilities are disclosed that support determination of timing advance for a physical uplink control channel (PUCCH) in joint acknowledgement feedback mode of a network having multiple timing advance groups (TAGs) configured per serving cell and multiple control resource set (CORESET) pool index values configured per bandwidth part (BWP). In a first aspect, a method of such capabilities includes receiving a configuration message including at least a feedback mode configuration configuring a joint acknowledgement feedback mode, a TAG configuration for each serving cell, and any CORESET pool indices for the BWPs of the serving cells. A user equipment (UE) receives downlink transmissions and determines a timing advance for a PUCCH with a joint acknowledgement message using the last downlink control information (DCI) message received scheduling the downlink transmissions. Alternatively, a UE may use a predetermined timing advance. Other aspects and features are also claimed and described.
