Abstract: Various communication systems may benefit from efficient communication. For example, various wireless systems may benefit from appropriate handling of user equipment identifiers over a PC5 interface in a PCS-based user equipment to network relay. A method can include assigning to a user equipment an identifier. The identifier can be configured to avoid a layer one identifier collision between the user equipment and other nearby user equipment.

Abstract: The use of PUCCH resources can be more efficient such as by sharing PUCCH resources between URLLC UEs and non-URLLC UEs in a controllable way enhanced with a smart deterministic downlink polling when needed. A method comprises receiving, by a user equipment from a network node of a communication network, information comprising a given physical uplink control channel resource instance allocated to the user equipment, wherein the physical uplink control channel resource instance is allocated to more than one user equipment including the user equipment; signaling the network node using an allocated physical uplink control channel resource instance in a given sub-frame; and, receiving polling form the network node, wherein the polling comprises an uplink grant.

Abstract: A technique includes receiving, by a first user device from a base station, control information indicating an assignment of the first user device to a first scheduling request sub-pool of resources of one or more scheduling request sub-pools, and an assignment of the first user device to a first data sub-pool of resources of one or more data sub-pools, wherein the sub-pools assigned to the first user device allow a contention-based grant-free mode transmission from the first user device of both a data and a scheduling request at the same time via different resources, wherein for at least a plurality of user devices no two user devices are assigned to both a same data sub-pool and a same scheduling request sub-pool.

Abstract: Systems, methods, apparatuses, and computer program products for fair resource sharing among user(s) or user groups in broadcast based D2D communications are provided. One method includes monitoring, by a cluster head, at least one user group sharing physical channel resources. The at least one user group may include at least one D2D user equipment. The method may further include calculating a current share of the physical channel resources for the at least one user group based on pre-configured fair sharing rules, determining when a maximum fair share of the physical channel resources are allocated to one of the at least one user group, determining whether remaining physical resources are sufficient. When the remaining physical resources are sufficient, the method may include issuing an indication to the one of the at least one user group. When the remaining physical resources are not sufficient, the method may include issuing a warning to the one of the at least one user group.

Abstract: Methods, corresponding apparatuses, and non-transitory computer readable mediums for a Proximity-based Service are provided. A method comprises receiving, from at least one user equipment, a resource utilization indication that indicates resources used by at least one user equipment for a ProSe device-to-device discovery procedure. The method also comprises determining, based on the received resource utilization indication, resources for the at least one user equipment to perform a subsequent ProSe device-to-device discovery procedure. The method additionally comprises signaling the determined resource to the at least one user equipment. With the claimed inventions, utilization efficiency of the radio resources may be improved and the complexity and overhead in allocating the resource for ProSe D2D discovery procedure may be lowered.
