Above all, a method for the user equipment to report the uplink scheduling request information to the base station in wireless telecommunication network is disclosed. Firstly, the user equipment computes the overall service data amount of all radio bearers in each group of radio bearers in the buffer of the user equipment; then the user equipment only reports group-related information of triggered one or more groups of radio bearers to the base station. The present invention further proposes a method in the user equipment in wireless telecommunication network for reporting the emergency information to the base station, that is, the user equipment judges whether each radio bearer is in the emergency, and when one or more radio bearers are in the emergency, the user equipment sends emergency indication information to the base station. By the combination of the two reporting method, the base station can realize efficient and fair scheduling.

Abstract: The invention provides solutions of discovering/identifying a small cell in a heterogenous communication network. In one solution, a macro base station determines whether a user equipment UE has approached to one or more small cells based upon location range information of respective small cells in a macro cell and estimated location information of an UE and if so, then the macro base station transmits a dedicated signaling to the UE, and the UE triggers a search based upon the dedicated signaling to search for the one or more small cells periodically. In another solution the UE determines whether the UE has approached to one or more small cells based upon received location range information, broadcast from a macro base station, of alert zones of respective small cells and estimated location information of the UE, and if so, then the UE triggers a search for the one or more small cells periodically. In another solution, the macro base station only transmits a dedicated signaling to the UE, including one ore more infrequently visited small cells.

Abstract: The present invention discloses methods and apparatuses for fast resource scheduling at the base station and fast transport format combination selection at the UE by using different pointers in base station and user equipment of wireless network. The TFCS in base station and UE are divided into TFCsbs each of which is a set of TFCs with the same transmission rate or the same transmission power, in the resource scheduling process at the base station, a pointer is used to select a proper TFCsb according to the resource request information from the UE and then inform UE of the relevant information. UE select the proper TFC by using another pointer from the TFCsb chosen at the base station. Because each of the scheduling process at the base station and the TFC selection process at the UE uses a pointer separately, the two processes can go more efficiently individually.
