Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect, a user equipment (UE) is configured to set a transmission power for an uplink communication based, at least in part, on a downlink communication. The UE is further configured to perform the uplink communication based, at least in part, on the set transmission power while concurrently performing the downlink communication. For example, in some aspects, the transmission power for the uplink communication may be set based on the type of downlink communication or based on one or more parameters associated with the downlink communication. In additional aspects, an algorithm may be used to set the transmission power for the uplink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information from a base station that indicates a set of resources for the UE to establish sidelink communications with another UE in a wireless network. The UE may transmit a first set of reference signals using a first set of beams to determine a set of neighboring candidate UEs for a sidelink connection. The UE may then transmit a second set of reference signals on a second set of beams to the neighboring candidate UEs, and may select a second UE located in the determined neighboring set using various beam scanning procedures. The UE may identify a transmit beam associated with the second UE, and may establish the sidelink connection using the identified transmit beam.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration indicating a set of occasions configured for sidelink communications for the UE. The sidelink communications may include at least one of sidelink traffic, semi-persistent scheduling traffic, or a combination thereof. The UE may receive a control indication associated with a radio network temporary identifier. The control indication may include a downlink control information. In some examples, the UE may skip a first pre-scheduled occasion of the set of occasions configured for sidelink communications based on the control indication, and may perform sidelink communications during a second pre-scheduled occasion of the set of occasions after skipping the first pre-scheduled occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a multiple listen-before-talk (LBT) bandwidths, where each LBT bandwidth is associated with one or more downlink control channel candidates of a search space for a control resource set. The UE may monitor the LBT bandwidths during a wakeup signal period for a wakeup signal from the base station. The UE may be configured with a total number of blind hypotheses in the set of blind hypotheses which is equal to or greater than a total number of LBT bandwidths. The UE may determine whether to wake up and monitor an on duration of a discontinuous reception cycle based on detection of the wakeup signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of communications from a corresponding plurality of transmission/reception points (TRPs) included in a coordinated multipoint network. At least two communications, of the plurality of communications, may have different redundancy versions from a common codebook, and may be received in a same transmission time interval (TTI). The UE may decode the plurality of communications using joint decoding. Numerous other aspects are provided.

Abstract: Network-controlled power control for side-link communications is disclosed. According to the described aspects, a power control framework is defined for network-controlled side-band or device-to-device (D2D) communications, in which transmission power for side-link communications may be stepped up enough for a base station in a connected mode with at least one of multiple user equipment (UE) devices to detect side-link communications between the UEs in order to take responsive action to enhance the reliability of the communications. The base station provides the configuration information to the UEs which may be used when preparing for transmissions of side-link traffic and/or feedback.

Abstract: Methods and apparatuses are provided which may be used in a base station and/or user equipment (UE) to support or otherwise provide device-to-device (D2D) communication in a shared radio frequency spectrum between candidate UEs. For example, a base station may determine that a first UE and a second UE are candidates for D2D communication, and provide and indicate that a Grant-free Uplink (GUL) resource allocation for D2D communication between the first and second UEs. The base station may further monitor the D2D communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more resources, assigned to multiple UEs, to be used to transmit a channel quality indicator (CQI) report; receive an indication of a threshold value associated with a range of channel conditions corresponding to a modulation and coding scheme (MCS) being used to communicate with the UE; and selectively transmit the CQI report on the one or more resources based at least in part on whether a measured channel condition is outside of the range of channel conditions by at least the threshold value. Numerous other aspects are provided.

Abstract: A unified frame structure for communicating in a synchronous and slotted mesh network is provided. Nodes within the mesh network are designated as primary and secondary nodes. For each transmission, a primary node may first send scheduling information to secondary nodes associated with the primary node. The receiver of the scheduled link may send a clear-to-send signal. For uplink scheduled transmissions, the receiver is the primary node. For downlink scheduled transmissions, the receiver is a secondary node. The transmitter of the scheduled link may receive the CTS signal from one or more proximate receivers, including a receiver associated with the scheduled transmission as well as other receivers not associated with the scheduled transmission. The transmitter of the scheduled link may estimate the signal to interference-plus-noise ratio of other links that are of higher priority and may then determine whether to yield or power back off the scheduled transmission.
