Abstract: Systems and methods configured for supporting multi-hop communications are described. Embodiments provide unavailable packet signaling by a base station aiding a multi-hop communication link. For example, the base station may transmit a predetermined “unavailable” message (e.g., an explicit and affirmatively transmitted message having predetermined content and/or format transmitted according to the schedule of the failed message) when an uplink data transmission in a multi-hop communication link fails or is otherwise currently unavailable. The unavailable packet signaling may be provided in association with a semi-persistent scheduling (SPS) and control channel scheduled retransmission technique, such as for supporting Internet of things (IoT), such as industrial Internet of things (IIoT), traffic. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support closed-loop transmit power control (TPC) for user equipment (UE) sidelink communications. TPC information may be provided, by a first UE receiving transmissions from a second UE, with respect to a sidelink implemented between the UEs. TPC information may be multiplexed with sidelink data traffic in a sidelink communication between UEs. The TPC information may include a TPC indicator and one or more TPC messages for providing TPC commands with respect to one or more sidelinks. The sidelink data traffic of some examples may include data-only traffic, such as semi-persistent scheduled (SPS) data traffic, that is decoupled from accompanying sidelink control information (SCI). Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an announcement that indicates a plurality of future resource reservations. The wireless communication device may transmit multiple sets of announcements that indicate one or more reservations and may vary the transmission frequency thereof based on proximity to the communications. The wireless communication device may transmit an announcement that indicates a future communication and a cancellation indication that indicates a cancellation of the communication. The wireless communication device may transmit a preemption indication that indicates that resources reserved for an announced future communication have been preempted for another communication. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between a plurality of user equipments (UEs). Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) to decode the sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) transmitted between a first UE and a second UE over sidelink communication without the need for the receiver UE (e.g., second UE) to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications.

Abstract: A user equipment (UE) in communication with a base station may utilize multiple code word (MCW) transmissions within a hybrid automatic repeat request (HARQ) process. An original transmission has a first transport block allocated to a first code word and a second transport block allocated to a second code word. Each transport block includes multiple code blocks grouped into code block groups. The UE receives a negative acknowledgement indicating that a subset of the code block groups were not successfully received. The UE retransmits the subset of the code block groups on at least one of the first code word or the second code word in a retransmission in the HARQ process. At least one code block is retransmitted on a different code word in the retransmission than in the original transmission.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A UE may receive a signal indicating a configuration for a symbol reserved for automatic gain control. Based on the configuration for the symbol reserved for automatic gain control, the UE may multiplex assistance data with the symbol reserved for automatic gain control. In some examples, the UE may multiplex physical sidelink shared channel data or physical sidelink control channel data or both physical sidelink shared channel data and physical sidelink control channel data with the symbol reserved for automatic gain control. The UE may then transmit the multiplexed assistance data in the symbol reserved for automatic gain control.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

Abstract: Systems, apparatus, methods, and computer-readable media that enable and support backward cancellation indication for sidelink transmissions are described. In a situation where a sidelink data transmission with respect to one or more resources previously reserved for sidelink communication is ineffectual, a sidelink transmission user equipment (UE) may indicate the ineffectual data transmission in a transmission opportunity subsequent to the transmission having an ineffectual data transmission, such as by transmitting a backward cancellation indication (BCI). The BCI may provide information to a corresponding sidelink receiver UE regarding the resource with respect to the ineffectual data transmission. The sidelink receiver UE may use information provided by the BCI in determining whether to alter utilization of signals received on resources of the ineffectual data transmission. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message which schedules a sidelink transmission from the first UE to a second UE on a first set of resources associated with a sidelink shared channel. The first UE may additionally receive a second DCI which indicates a second set of resources which are cancelled from the first set of resources. Based on the cancellation indication, the first UE may modify or cancel at least a portion of the sidelink transmission originally scheduled for the second UE, and may transmit the modified sidelink transmission over a portion of the first set of resources in accordance with the cancellation indication, the first DCI, and the second DCI.
