Abstract: Various communication systems may benefit from load control. For example, systems that employ device-to-device discovery signal transmissions may benefit from such load control. A method can include determining a first classification of a user equipment according to desired or allowed transmission probability. The method can also include configuring a transmission probability based on the first classification. The method can further include operating the user equipment based on the transmission probability.

Abstract: A method may include transmitting, by a user equipment, a data packet to a network entity. The method may further include starting, by the user equipment, a timer with a first value associated with the transmission to the network entity. The method may further include checking, by the user equipment, for feedback from the network entity associated with the transmission to the network entity. The method may further include determining, by the user equipment, that no feedback for the transmission has been received within the associated timer, or a negative acknowledgement has been received without the corresponding resource allocation for re-transmission. The method may further include in response to receiving no feedback associated with the transmission within the associated timer, or receiving a negative acknowledgement without the corresponding resource allocation for re-transmission, re-transmitting, by the user equipment, the data packet to the network entity.

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: To efficiently use uplink resources while fulfilling latency requirements of low latency services, an access node, a resource pool allocated for contention based transmissions of low latency communication services may be used for transmissions of data services, since an access node providing the resource pool, is caused to send, in response to not being able to decode terminal device identification information from a sensed scheduling request, a stop instruction to terminal devices that are using the resource pool to transmissions of the data services. Further, the terminal device that sent the scheduling request is caused to use the resource pool for transmissions of the low latency service if a response is not received within predetermined time.

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.
