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 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: 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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include monitoring, via one or more sensors of a first user equipment (UE), at least one of a thermal overload condition or an exposure condition associated with a first communication link between a first UE and a base station. Based on the monitoring, for example, the first UE may determine that at least one of the thermal overload condition or the exposure condition exceeds a corresponding predetermined switch threshold. Based on the determining, a second communication link may be established between the first UE and a second UE, where the second UE is configured to operate as a relay UE, for communications between the first UE and the base station via (in-part) the second communication link.

Abstract: Methods, systems, and devices for wireless communication are described. A first cell may receive a message indicating that a second cell has a priority transmission scheduled using a transmit time interval (TTI) that is shorter than a TTI used by the first cell. The first cell may limit, based on the message, a communication parameter associated with communications between the first cell and a user equipment (UE) during the scheduled priority transmission.

Abstract: Methods, systems, and devices are described for wireless communication. Device-to-device (D2D) communications may benefit from the use of a relay facilitating communications between mobile devices. Relays which are not power-limited, such as if the relay is connected to a power grid, may continuously monitor the communication medium. A relay may monitor D2D communications and determine a D2D pair for which to attempt to facilitate communications. The relay may identify a first message from a first mobile device to a second mobile device, and may transmit a second message to the second mobile device. The second message may be transmitted using the same resources as the first message, and may include at least a portion of the first message. The relay may receive a response from the second mobile device and may transmit information about the relay to the second device before facilitating communications between the D2D pair of mobile devices.
