    Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.

    Abstract: An acknowledgment (ACK)/negative-ACK (NACK)-based relaying scheme for uplink coverage improvement is provided. A relay station receives, from a destination device, a first feedback transmission associated with the first data transmission. The relay station determines whether the destination device successfully receives the first data transmission based on the first feedback transmission. The relay station communicates, with the destination device, a second feedback transmission associated with the first data transmission when the destination device does not successfully receive the first data transmission. The relay station communicates, with the destination device, a second data transmission associated with the second feedback transmission, in which the second data transmission comprises at least a portion of the first data transmission.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support feedback for mixed grant types. In a first aspect, a user equipment (UE) is configured to determine a threshold associated with a number of bits for feedback of one or more physical downlink shared channel (PDSCH) grant types. The UE is further configured to transmit a feedback message including feedback information for one or more received PDSCHs associated with the one or more PDSCH grant types. A number of bits of the feedback information included in the feedback message for the one or more received PDSCHs associated with the one or more PDSCH grant types is less than or equal to the threshold. Other aspects and features are also claimed and described.

    Abstract: One apparatus may be configured to transmit a set of reference signals on shared resources of a first communication link and a second communication link, the set of reference signals indicating an interference channel on the shared resources. The apparatus may further communicate data or control information on the first communication link following transmission of the set of reference signals. Another apparatus may be configured to detect a signal on shared resources of a first communication link and a second communication link, the signal being indicating an interference channel on the shared resources. The other apparatus may further perform channel estimation on the interference channel based on detecting the signal. The other apparatus may further communicate data or control information on the first communication link based on the channel estimation on the interference channel.

    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may determine to change a first slot format used when operating in a half-duplex mode based on a traffic pattern or a channel quality, or both, and may transmit a request to change the slot format to a base station. The request may include information relating to a slot format based on the traffic pattern or the channel quality, or both, such as an explicit indication of a slot format or a request for a different resource distribution between uplink symbols, downlink symbols, or flexible symbols, or any combination thereof. The base station may receive the request to change the slot format and may transmit an indication of a second slot format to the UE based on the request. The base station and the UE may communicate using the second slot format.
