A communication device receives an uplink grant from a node of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device in reoccurring time intervals. For each of these time intervals, the communication device selects between an active mode and an inactive mode. In the active mode the communication device performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device performs no uplink transmission in the allocated uplink radio resources.

Conditional uplink radio resource utilization in a cellular network

An apparatus, system and method are introduced for controlling a user equipment in a first network with a resource control server. In one embodiment, the resource control server provides instructions over the second network to the user equipment of actions to be taken based at least in part on congestion within the first network.

System and method for congestion control in a communication system

A node () of a cellular network sends an uplink grant () to a communication device (). The uplink grant indicates uplink radio resources allocated to the communication device () in reoccurring time intervals. In response to detecting a need for an uplink retransmission () by a further communication device (') on at least a part of the allocated uplink radio resources in a certain one of the time intervals, the node () sends control information () to the communication device (). The control information () temporarily disables utilization of at least this part of the allocated uplink radio resources in at least this certain time interval by the communication device ().

Collision avoidance for uplink radio resource allocation in reoccurring time intervals

A communication device receives an uplink grant from a node of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device in reoccurring time intervals. For each of these time intervals, the communication device selects between an active mode and an inactive mode, in the active mode the communication device performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device performs no uplink transmission in the allocated uplink radio resources.

A method for control of a telematic control unit comprises obtaining of information of discontinuity-beneficial conditions, associated with a vehicle to which the telematic control unit is connected. The discontinuity-beneficial conditions indicate that an extended discontinuous reception mode would be beneficial for the telematic control unit and the vehicle to which it is connected. A determination of an extended discontinuous reception time for the telematic control unit to propose is obtained. A request for an extended discontinuous reception mode for the telematic control unit is initiated as a response to obtained discontinuity-beneficial conditions, proposing the determined extended discontinuous reception time. A telematic control unit configured for performing such a control method is also presented.

In one aspect, a wireless device receives a first data transmission from a base station in a first subframe interval and transmits HARQ feedback and/or CSI to the base station in a subsequent subframe interval, within a duration that is less than a maximum transmission duration that is possible within the subsequent subframe interval. In another aspect, a base station transmits a first data transmission to a wireless device in a first subframe interval and receives HARQ feedback and/or CSI from the wireless device in a subsequent subframe interval, within a duration that is less than a maximum transmission duration that is possible within the subsequent subframe interval.

Short PUCCH in uplink sPUCCH

A communication device checks whether data is available in an uplink data buffer of the communication device for uplink transmission employing uplink radio resources, the uplink radio resources being previously allocated to the communication device in reoccurring time intervals. Depending on said checking, the UE controls the transmission of a channel reference signal.

Control of channel reference signal transmission in a cellular network

Depending on data () available in an uplink data buffer () of a communication device () for uplink transmission and further depending on uplink radio resources previously allocated to the communication device () for the uplink transmission in reoccurring time intervals, a fraction (-) of the data () available in the uplink data buffer () is determined. A buffer status report is sent to the cellular network. The buffer status report indicates the determined fraction (-) of the data ().

A non-transitory computer readable medium has instructions stored therein to be executed by a packet processing unit (PPU) in a communications network to allow a plurality of PPUs in the communications network to independently allocate IP addresses from a shared pool of IP addresses. The plurality of PPUs collectively maintain a distributed hash table (DHT). The DHT stores a distributed block allocation table (DBAT) and a plurality of distributed address allocation tables (DAATs). The DBAT includes an entry for each of a plurality of blocks of IP addresses to indicate which of the plurality of blocks are allocated to which of the plurality of PPUs. Each of the plurality of DAATs corresponds to one of the blocks in the DBAT and includes an entry for each of the IP addresses in that block to indicate which of the IP addresses in that block are allocated to which user entities.

Distributed IP allocation and de-allocation mechanism in a communications network having a distributed S/PGW architecture

A communication device () receives an uplink grant from a node () of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device () in reoccurring time intervals. For each of these time intervals, the communication device () selects between an active mode and an inactive mode. In the active mode the communication device () performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device () performs no uplink transmission in the allocated uplink radio resources.

A non-transitory computer readable medium has instructions stored therein to be executed by a packet processing unit (PPU) in a communications network to allow a plurality of PPUs in the communication network to route data packets. The plurality of PPUs collectively maintain a distributed hash table (DHT). The DHT stores a distributed routing table (DRT), where the DRT includes a DRT entry that maps a key to a value. The key is based on a destination Internet Protocol (IP) address and an access point name (APN) associated with an IP session of a user entity (UE). The value represents both an IP address of one of the plurality of PPUs currently serving the IP session of the UE and an IP session identifier that identifies, to that PPU currently serving the IP session of the UE, the IP session of the UE.
