A method performed in a network node of a cellular network that also includes a wireless device, the wireless device being in a discontinuous reception mode having receiving periods and idle periods. The method involves transmitting a first control signal to the wireless device during a receiving period for the wireless device; determining that a first control signal is likely to have failed to be correctly received by the wireless device; and determining that a second control signal needs to be transmitted to the wireless device, the second control signal corresponding to the first control signal. When the wireless device is in an idle period, the method further involves postponing any transmission of the second control signal until the wireless device is in a receiving period; and transmitting the second control signal to the wireless device when the wireless device is in the receiving period.

Methods and arrangements for mitigating or avoiding inter cell interference on a control channel on which scheduling request are transmitted from UEs to a serving base station. The solution relates to classifying the UEs based e.g. on the type of services applied by the UEs, and allocating resources on the control channel based on the classification.

A method of a wireless communication device comprised in a cluster of devices is disclosed. The devices of the cluster are associable with a cluster subscription identifier of a subscription providing communication between a network node and the cluster (based on a single identifier associated with the cluster) when one or more of the devices are in a cluster communication mode. The wireless communication device may have one of a cluster communication gateway role and a cluster internal communication role. The cluster communication gateway role comprises transmitting a cluster communication beacon signal, maintaining a communication link to the network node, and maintaining peer-to-peer communication links to the other devices of the cluster. The cluster internal communication role comprises maintaining at least a peer-to-peer communication link to a specific device having the cluster communication gateway role. A received signal is scanned for a beacon signal and (if the beacon signal is found) it is determined, based on the cluster subscription identifier, whether the beacon signal is associated with the subscription. If the beacon signal is associated with the subscription, the identity of the specific device is determined based on the beacon signal, a cluster communication attach request is transmitted to the specific device, and a cluster communication attach response is received from the specific device. If the cluster communication attach response comprises a cluster communication attach acknowledgement, the wireless communication device transfers to the cluster communication mode and assumes the cluster internal communication role.

A method in a base station for adapting link adaptation of a transmission between a user equipment and the base station is provided. The link adaptation relates to an initial value of a Block Error Rate, BLER, related to the transmission. The base station decides that the user equipment is in congestion responsive to a scheduling bit rate for the transmission in relation to a rate of data packets arriving to or being sent by the user equipment being below a first threshold. Responsive to the user equipment being in congestion, the base station adapts the link adaptation by increasing the value of the BLER of the link adaptation in relation to the initial value, until the user equipment is out of congestion or until the base station detects that any one of the user equipment and the base station tries to send high priority data.

A method () for a controlling node of a cell () in a cellular system, the method comprising () the use of Radio Link Control Acknowledged Mode, RLC AM, and scheduling () transmissions in the downlink and uplink directions to/from User Equipments, UEs (), in the cell (). The scheduling comprises taking into account a priority which each UE has for its transmissions, and counting () the number of scheduled transmissions for a UE in a first of said directions since its latest scheduled transmission in the other of said directions. If () the count has reached a predetermined value, the priority of the UE in the other of said directions is increased (), and when () the UE has been scheduled for a transmission in said other direction, the counting in said first direction is restarted () from an initial value.

Methods and devices to improve the efficiency of uplink scheduling among user equipment (UEs) are disclosed. In one aspect, a base station with a scheduler utilizes a notional or holding 'LCG,' in addition to LCGs that correspond to an LCG to which a UE maps one or more logical channels. This notional LCG is a dedicated LCG for maintaining temporary priority information based on the receipt of a scheduling request (SR) from the UE.

A method and base station () of a first cell (), for&#x2014;controlling inter-cell interference in a cellular network when Discontinuous Reception, DRX, is applied for User Equipments, UEs. The base station selects a DRX scheme with active periods that are separated in time from active periods of a DRX scheme used for UEs in DRX mode in a neighboring second cell (). The selected DRX scheme is then used for a first UE () in DRX mode in the first cell to avoid interference between transmissions of signals in the active periods to the first UE in the first cell and transmissions of signals in active periods to the UEs in the neighboring second cell.

The present disclosure concerns radio communication. In one of its aspects, the technology presented herein concerns a method for selecting the most suitable secondary carrier for carrier aggregation when employing a combined radio cell including multiple radio sectors A, A, Aof a first Cell (Cell A) and multiple radio sectors B_x, B_y, B_z of a second cell (Cell B).

A method in a base station for adapting prioritization of a service of a user equipment over services of other user equipments is provided. The prioritization relates to a transmission between the base station and the user equipment at a scheduling occasion. The prioritization relates to an initial value. The base station decides () that the user equipment is in congestion, when an instant scheduling bit rate for the transmission in relation to a bit rate related to the service is below a first threshold. When the user equipment is in congestion, the base station adapts () the prioritization by down prioritizing the service of the user equipment in relation to the initial value, until a timer has expired.
