Abstract: A method, apparatus, and computer program product are described that receive an indication of power levels at the base station in a wireless communications system from each user equipment of user equipments served by the base station and determine whether at least one user equipment of those user equipments is capable to overlap at least one same time-frequency resource as at least one user equipment of a remainder of those user equipments. In response to the determination that at least one user equipment is capable to overlap with at least one user equipment of the remainder, then such overlap is scheduled. Based on the overlap being scheduled, packets from the one or more user equipments received are then decoded using an advanced receiver process.

Abstract: Improved techniques of reducing latency in UL positioning include generating a priority indication by the LMF for all UE requiring UL positioning. For example, an LMF can generate a priority list identifying UEs within a network that may be considered by a serving network node (gNB) for positioning prioritization. In some implementations, the serving gNB indicates that prioritizing all of the identified UEs would require more network resources than are available. In such a case, the LMF obtains latency measurement values for TRPs in the network. Based on the latency measurement values obtained, the LMF performs a configuration operation on at least one of the TRPs to reduce the UL positioning latency to an acceptable value.

Abstract: A method and apparatus may include determining that downlink communication is to be scheduled for transmission to user equipment. The method may also include scheduling the downlink communication. The method may also include scheduling uplink communication. The uplink communication is transmitted by user equipment to the network node. The uplink communication and the downlink communication are transmitted such that (1) uplink frequency resources are the same as downlink frequency resources, (2) uplink frequency resources are contained within downlink frequency resources, or (3) uplink frequency resources overlap with downlink frequency resources. The method may also include signaling user equipment to ignore a carrier sensing mechanism. User equipment transmits the uplink communication at a time specified by the network node.
