Patent ID: 8737365

Claim:
A method of allocating uplink radio resources to a mobile device; wherein uplink and downlink timeslots are instantaneously allocated to the mobile device by a base station; wherein uplink and downlink timeslots are flexibly assigned to the mobile device by the base station; wherein a sum of the instantaneously allocated uplink timeslots and the instantaneously allocated downlink timeslots within a predetermined period is less than a total number of assigned time slots and the sum does not exceed a predetermined maximum; wherein the resources are allocated in a reduced transmission time interval configuration; wherein an indication of the uplink timeslot allocation is received from the network in a downlink timeslot, or downlink timeslot pair; directing the mobile device to transmit only in one uplink timeslot pair, and wherein the total number of assigned time slots is greater than the sum of the instantaneously allocated uplink timeslots and the instantaneously allocated downlink timeslots within said predetermined period, comprising further receiving the indication of the allocation for an uplink timeslot pair in a corresponding downlink timeslot, or in a corresponding downlink timeslot pair, in a radio block period preceding a radio block period to which the indication relates.
