There is provided, for example, an apparatus, which is caused to select a transmission power configuration for a communication with at least one user terminal taking place on component carriers of a carrier aggregation configuration within a shared band, wherein the selection is between a low transmission power configuration applying a transmission power below a predetermined power threshold without a listen-before-talk approach and a high transmission power configuration applying a transmission power of at least the predetermined power threshold; and upon detecting that the selected transmission power configuration needs to be informed, cause an indication of the selected transmission power configuration to the at least one user terminal and at least one secondary cell.

Power control for carrier aggregation on shared bands

The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.

A method and apparatus are therefore provided that may enable the provision of M2M communication in a wireless network environment. In this regard, for example, relatively low power devices (specifically referencing low transmission power) such as sensors or other machines in an M2M system may be enabled to initiate communication with a network through a mobile terminal in a more reliable and robust manner. The machine may transmit a busy-signal to request a reservation of a machine access slot on a machine access control channel to reserve the slot before transmitting any machine information or data to reduce the likelihood of collisions with other machines. Once the machine has reserved the machine access slot, the machine may transmit identification information via randomly selected frequency division multiplexed or code division multiplexed resources to further reduce the likelihood of collisions with other machines. Thus, delays in establishing connections may be reduced or eliminated.

In a heterogeneous network environment where both high and low power nodes are sharing the same channel/frequency, explicit signaling in a downlink control message is used to select whether scheduling information SI is to be transmitted by a user equipment UE with a data payload or without a data payload. For the case where the selection is that SI is to be transmitted with a data payload, the downlink control message is used for the UE to select a transport format combination TFC for transmission of the SI with the data payload. Else for the case where the selection is that SI is to be transmitted without a data payload, the downlink control message is used for the UE to select transmit power for the transmission of the SI without the data payload.

Device-to-device (D2D) communication is one alternative to communication between devices through a radio access network. One interesting D2D communication method is reuse-mode D2D, where D2D nodes communicate with each other using the same uplink (UL) radio resource that is being used by some other cellular user equipment(s) (UEs). In other words, the UL cellular resources occupied by cellular UEs are reused by D2D nodes in their short-range communications. Centralized control of D2D communication can be performed by appropriate signaling between a D2D-capable UE and an evolved Node B (eNB).
