摘要： There are disclosed a method, base station and computer-readable storage media for downlink power allocation in a wireless communication system. The method may comprise obtaining information on positions of user equipments in a cell; classifying the user equipments into cell-edge user equipments and non-cell-edge user equipments based on the obtained information on the positions of user equipments in the cell; and performing downlink power allocation by increasing power allocated to at least one of physical downlink control channels (PDCCH) for scheduled user equipments of the cell-edge user equipments and common reference signals with power borrowed from at least one of downlink common channels for scheduled user equipments of the non-cell-edge user equipments. With embodiments of the present disclosure, downlink transmit power can be allocated efficiently and thus cell downlink coverage may be increased at a low cost.

摘要： One embodiment of the present disclosure relates to a method for transmitting a random access preamble in a transmitting sub-frame at a terminal device. The method comprises: creating a random access preamble such that it comprises a plurality of random access sequences; dividing the plurality of random access sequences into a number Nc of groups, each of groups including two or more random access sequences; performing code division multiplexing with respect to the groups of the plurality of random access sequences in a frequency domain, based on an orthogonal cover code selected for the terminal device from a pre-defined code set; and transforming signals after the code division multiplexing into the time domain. According to an aspect of the present disclosure, there are provided corresponding methods and devices.

摘要： Methods and apparatuses for a handover using dedicated random access resources have been provided. A method implemented in a target base station, BS, of a cellular radio system during a handover of a user equipment, UE, from a source BS to the target BS is provided. The method comprises: receiving a handover request from the source BS; allocating a dedicated random access channel, RACH, preamble and a RACH configuration associated with the dedicated RACH preamble, to the UE for accessing the target BS; and transmitting a handover response including information of the dedicated RACH preamble and the RACH configuration to the source BS. The dedicated RACH preamble is different from any RACH preamble preconfigured in the target BS at least in terms of a root sequence in the RACH configuration.

摘要： The invention relates to Coordinated Scheduling for a Time Division Duplex (TDD) network. In a method for User Equipment (UE) scheduling by a base station in a TDD network, the base station receives scheduling decision from at least one neighboring cell of the base station, and schedules a UE among a plurality of UEs in the serving cell of the base station based on the scheduling decision from the at least one neighboring cell and based on smart antenna information. The inter-cell interference is suppressed and therefore the network performance is improved.
