Method and device for channel resource allocation, base station and user equipment

Disclosed are a method and device for channel resource allocation, a base station and a piece of user equipment. The method includes: determining load information of a cell; when it is judged that the cell reaches a congestion state according to the load information, allocating channel resource allocation information for a new piece of user equipment, and the channel resource allocation information includes: a first DPCH Pilot bit transmission power offset and/or a first pilot-frequency Pilot bit number, wherein the first DPCH Pilot bit transmission power offset is lower than the DPCH Pilot bit transmission power offset which is allocated for the user equipment under a non-congestion state and the first pilot-frequency Pilot bit number is smaller than the pilot frequency Pilot bit number which is allocated to the user equipment under a non-congestion state; and sending the channel resource allocation information to the new user equipment. When the load of the cell is high, reducing the transmission power of a downlink DPCH so that the downlink throughput rate of the cell is improved and call drop rate is reduced.
