Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a sidelink scheduling request for groupcast sidelink communications with a set of one or more UEs. The base station may determine one or more UEs of the set of UEs and time-frequency resources for groupcast sidelink communication between the first UE and the one or more UEs. The first UE may receive, from the base station, a groupcast sidelink grant that indicates time-frequency resources for groupcast sidelink communications between the first UE and one or more UEs. The first UE may transmit, via the time-frequency resources indicated by the groupcast sidelink grant, a groupcast sidelink message to the one or more UEs. The one or more UEs may also receive the sidelink grant, and may monitor the time-frequency resources for a groupcast sidelink communication from the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).

A user equipment (UE) may identify that an uplink data transmission scheduled for transmission by the UE in a first transmission time interval overlaps with multiple uplink control transmissions also scheduled for transmission by the UE during corresponding second transmission time intervals that are shorter in duration than the first transmission time interval. The UE may determine that the multiple uplink control transmissions satisfy a scheduling constraint that is based at least in part on an uplink control transmission type of the multiple uplink control transmissions that overlap with the uplink data transmission. The UE may transmit the uplink data transmission and the multiple uplink control transmissions based at least in part on the scheduling constraint being satisfied.

Abstract: A user equipment (UE) initiates a positioning session based on ranging in a distributed system of UEs. The positioning session includes a plurality of anchor UEs with known positions that provide information including ranging information and their positions to the initiator UE in post-ranging messages. The initiator UE identifies anchor UEs that provide information that does not significantly contribute to the final position estimate for the initiator UE. The initiator UE, for example, may generate position estimates and associated accuracy levels for different subsets of anchor UEs and may use the accuracy levels to identify a subset of anchor UEs that may be used for positioning in place of the full set of anchor UEs without a significant loss of accuracy. Selected UEs are excluded from providing post-ranging messages in subsequent positioning sessions to reduce signaling overhead and improve efficiency.

Abstract: Methods, systems, and devices for wireless communications are described that provide for measurements for narrow-band (NB) Internet of Things (IoT) devices. A user equipment (UE) may receive a cell-specific reference signal (CRS) during a paging occasion and via a non-anchor carrier. The UE may process the CRS by determining and/or making quality measurements of the paging carrier. The quality measurements may be used to determine whether a paging occasion should be terminated early to conserve UE power and to prevent an extended “on” duration during the discontinuous receive cycle of the UE. In some examples, the UE may combine statistics and/or measurements based on processing of both the CRS and a narrow-band reference signal (NRS).

A communication network device may receive the anomaly notification message, and in response to determining that the anomaly notification message was received via the anomaly-specific network communication link may associate the anomaly notification message with an anomaly priority that is higher than a normal traffic priority.
