Abstract:
1. A method comprising: transmitting, by a network element, allocation information for suggesting allocation of sets of transmission resources; negotiating at least one configurable allocation rule for associating at least one sequence of sets of transmission resources with at least one communications device in an active state to allow discontinuous reception at the at least one communications device, wherein at least one of said at least one communications device is configured to monitor allocation information of sets of transmission resources associated with the at least one communications device and wherein said at least one configurable allocation rule defines that a communications device monitors allocation information at least periodically using a first period and a second period , which is shorter than the first period, and conditionally monitors allocation information periodically using the second period wherein the at least one configuration allocation rule defines that the second period is used on one of the following conditions: the allocation information monitored using the first period does not indicate transmission resources allocated to the communications device until the communication device determines transmission resources allocated to the device, the allocation information monitored using the first period indicates the start of transmission resources allocated to the communications device until the allocation information indicates no more transmission resources allocated to the communication device, and information carried by transmission resources associated with the first period is erroneously received by the communications device wherein the second period is used for retransmissions until a positive acknowledgement is received; and allocating transmission resources for said at least one communications device based at least on said at least one configurable allocation rule.
