摘要： A method of operating a network node grants a first resource for UE transmissions and identified by a time identifier mapped to a first synchronization reference and by a frequency identifier. The time and frequency identifiers are identified by a relative resource identifier. A second resource is reserved for transmissions by the UE, and is identified by the time identifier mapped to a second synchronization reference and by the frequency identifier. The first and second synchronization references can be used by a UE for transmissions synchronization. The relative resource identifier is sent to the UE for use in controlling transmissions. Responsive to information reported by the UE indicating the UE is using the second synchronization reference for transmissions synchronization, a new relative resource identifier is sent that identifies a time identifier mapped to the second synchronization reference that corresponds to a location of the second resource and identifies the frequency.

摘要： A method in a wireless device is disclosed. The method comprises sending a scheduling request to a network node, and receiving, from the network node in response to the scheduling request, a grant of uplink resources. The method further comprises determining whether the granted uplink resources are at least equal to or larger than the resources required for transmission of both a buffer status report (BSR) and a sidelink BSR, and upon determining that the granted uplink resources are at least equal to or larger than the resources required for transmission of both the BSR and the sidelink BSR, communicating the BSR, and the sidelink BSR to the network node in a single medium access control (MAC) protocol data unit (PDU).

摘要： There is disclosed herein systems, methods, and apparatuses for floor control in a push to talk communication session. According to certain embodiments, a method for floor control comprises, prior to transmitting a first message to one or more wireless devices, determining, at a first wireless device, a priority of the first message. The method also comprises determining, at the first wireless device, whether a floor is available for transmitting the first message based on the determined priority of the first message. The method additionally includes, upon the floor being available, transmitting the first message from the first wireless device to the one or more wireless devices. The method additionally includes transmitting the first message from the first wireless device without the first wireless device first requesting the floor from a remote floor controller.

摘要： A technique relating to resource configuration in a wireless communication network. A terminal device in the wireless communication network receives information about supplemental resource from a source cell. Then the terminal device determines a time interval, in which the supplemental resource is available to the terminal device, in a transition period of a handover from the source cell to a target cell based on a timer associated with a random access procedure in the handover. In this way, the terminal device may use the supplemental resource during the handover.
