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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first sidelink pathloss based at least in part on a first sidelink reference signal from a second UE. The first UE may also determine a second sidelink pathloss based at least in part on a second sidelink reference signal received from a third UE. The first UE may transmit, during a transmission time interval, a first sidelink transmission to the second UE using a first transmit power that is based at least in part on the first sidelink pathloss and a second sidelink transmission to the third UE using a second transmit power that is based at least in part on the second sidelink pathloss. The first sidelink transmission may be transmitted at a first frequency and the second sidelink transmission may be transmitted at a second frequency.

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 communication utilizing a data channel search space for initial data transmissions and retransmissions are described. In one aspect, a base station may configure a data channel search space and a plurality of monitoring occasions for a wireless device. The data channel search space may include a plurality of sets of decoding candidates on which the wireless device may receive data transmissions from the base station. At least one of a frequency location, a resource size, or a modulation and coding scheme can vary between different sets of decoding candidates. The wireless device performs blind decoding in its data channel search space to communicate with the base station.

Abstract: Methods, systems, and devices for wireless communications are described. One or more user equipments (UEs) may support reserved resource indications for sidelink systems. In some examples, a first UE may transmit a first sidelink control message to at least a second UE in a first transmission time interval (TTI), which may schedule a first set of time-frequency resources for a sidelink message. The first UE may transmit the sidelink message to the second UE using the first set of time frequency resources. After transmitting the sidelink message, the first UE may transmit a second sidelink control message to the second UE in a second TTI, which may indicate the first set of time-frequency resources used for transmission of the sidelink message. In some examples, the second UE may perform a decoding procedure for the sidelink message based on the second sidelink control message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may measure a set of reference signal receive power (RSRP) metrics for reference signals including one or more reference signals from a base station and one or more reference signals from a controller associated with the device; and determine, based at least in part on the RSRP metrics, a configuration for receiving communications from the controller via a direct communication link with the controller or via the base station. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied. Numerous other aspects are provided.

Abstract: Techniques for obtaining wideband channel state information (CSI) for a plurality of subbands is described. A two-stage procedure may be used to obtain the wideband CSI. At a first stage, a base station may broadcast a wideband channel state information reference signal (CSI-RS) that includes a plurality of subbands. The wideband CSI-RS may be received by any user equipment (UE) within range of the base station. The UE may select one or more subbands in the wideband CSI-RS for communication with the base station. To indicate which subbands were selected, at a second stage, the UE may transmit a narrowband sounding reference signal (SRS) in each of the selected subbands. The base station may schedule traffic for the wireless communications system based on the narrowband SRSs.

Abstract: Base stations of neighbor cells can coordinate with each other in allocating grant-free uplink (GUL) resources for a device-to-device (D2D) connection or channel between user equipments (UEs) across the neighbor cells. The base stations coordinate to determine a condition conducive to D2D communication between the UEs. If the condition exists, the base stations coordinate to allocate network resources for D2D communication between the UEs, and establish a D2D connection between the UEs using the allocated network resources for D2D communication.
