Patent ID: 8817724

Claim:
A method for transmitting an Enhanced Dedicated Channel (E-DCH) Random Access Uplink Control Channel, comprising the steps of: judging, by a user equipment, whether a plurality of E-DCH Random Access Uplink Control Channel transmission processes temporally overlap comprising: transmitting an enhanced uplink synchronization code to a base station to trigger at least one of the E-DCH Random Access Uplink Control Channel transmission processes; and receiving a synchronization command from the base station before transmitting scheduling information to the base station; and if the user equipment judges overlapping, then the user equipment selecting to perform one of the E-DCH Random Access Uplink Control Channel transmission processes and returning scheduling information and an identifier of the user equipment to the base station over the E-DCH Random Access Uplink Control Channel; wherein the plurality of E-DCH Random Access Uplink Control Channel transmission processes comprise: the E-DCH Random Access Uplink Control Channel is triggered by sending E-DCH data; and the E-DCH Random Access Uplink Control Channel is triggered by uplink synchronization of the base station; and the user equipment sending E-DCH data, stopping the uplink synchronization with the base station, and does not trigger uplink synchronization of the base station while sending the E-DCH data, when the sending of E-DCH data from the user equipment temporally overlaps with the uplink synchronization with the base station.
