Abstract: An access point of a wireless communication system configures a carrier for communication with one or more wireless devices associated with the access point. Based on a backoff counter maintained by the access point, the access point contends for access to the carrier to transmit data. In response to another access point winning contention for access to the carrier, the access point cooperates at least with the access point winning the contention by sharing a transmission opportunity reserved on the carriers by the access point winning the contention and transmitting at least a part of the data in the shared transmission opportunity. During the shared transmission opportunity the access point pauses the backoff counter.

Abstract: A boost is provided in an overloaded system by distinguishing nodes with a “bad” traffic history from nodes with a “good” traffic history. In so doing, a core network node is able to apply additional resources to the node(s) having a “good” history in the form of a boost factor. Based on a system capacity and a working point, e.g., a critical number of active nodes with a “bad” traffic history, the core network node may determine a throughput history limit belonging to the “bad” traffic history. Responsive to expected requirements for a newly active node (i.e., a node having a “good” traffic history), the core network node determines a boost factor for the newly active node, applies the boost factor to the average resources allocated to the nodes with the “bad” traffic history to determine boosted resources, and allocates the boosted resources to the newly active node.

Abstract: Security and privacy mechanisms are provided to protect the L2 identifiers used in groupcast communications over the sidelink (e.g., PC5 interface) without requiring a UE to periodically refresh the L2 identifiers, which may cause extra signaling overhead, increased latency and greater risk of synchronization issues. To prevent tracking of a UE, a group identifier (ID) is used as a source layer 2 (L2) ID in groupcast messages. Additionally, a message authentication code (MAC) is introduced into the group discovery procedure to authenticate the UE sending a group discovery request.
