Apparatus and method for communication are provided. The apparatus includes a controller for controlling the transmission and reception of data on one or more carriers utilizing Time Division Duplexing and frames including sub frames, where multiple carriers utilized by different apparatuses are synchronized with each other and a predetermined number of sub frames of each frame are reserved for predetermined transmission directions and a scheduler for allocating the rest of the sub frames carrier specifically either in downlink or uplink direction.

Resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers can be determined by a station. Information indicative the at least one component carrier and the associated resources is then communicated to another station for configuration of the other station. A trigger is then sent for reference signalling, and in response to the trigger, at least one reference signal is sent from the other station using the indicated at least one component carrier and resources.

There is proposed a mechanism by means of which resources for a data transmission between a user equipment and a base transceiver station are set. For this purpose, a resource dedicated to the user equipment (like an SR resource) is combined with at least one contention based resource allocated to a contention based transmission by the user equipment (like a CB-PUSCH resource). The at least one contention based resource to be combined is selected by executing a mapping according to a predetermined rule and based on an information indicating a specific resource element dedicated to the user equipment to at least one set of available contention based resources, and by determining an information identifying at least one resource element of the at least one contention based resource.

A method is disclosed for scheduling packet data in a communications system. The method includes configuring, in a network apparatus, semi-persistent transmission resources to a user equipment via higher layer signalling, wherein the configuring step includes pre-allocating a data transmission resource and assigning a scheduling request resource to the user equipment. A confirmation message is transmitted to the user equipment from the network apparatus, wherein the confirmation message informs the user equipment that the user equipment is able to start transmitting data on a physical uplink shared channel PUSCH to the net-work apparatus by using the pre-allocated data trans-mission resource and a pre-configured transmission format, wherein the pre-allocated data transmission resource is linked to the corresponding confirmation message, the corresponding confirmation message being linked to the corresponding semi-persistently assigned scheduling request resource.
