Abstract
The present invention provides a method by which users may be moved between time slots or between base stations in order to better utilize the MCPA output power resources. According to an exemplary embodiment of the present invention, the power of all transceivers served by a certain MCPA is compared to a threshold value X. The value X is at least related to the capability of the MCPA in terms of output power. If at no times (i.e., at all time slots), the sum of the output power exceeds the threshold value X, it is assumed that the MCPA can handle all simultaneous transmissions. If, during at least one time slot it is found that the required output power exceeds the capability of the serving MCPA, then a reallocation or load sharing algorithm is invoked. The reallocation algorithm searches for time slots to which a reallocation could be performed within the same base station or number of transceivers served by the MCPA. If no time slots can handle users from the time slot in which the MCPA limit is exceeded, then a load sharing algorithm is activated and one starts to look for transmission resources in transceivers served by other MCPAs, e.g., other cells. A number of alternative embodiments of the invention is described, which relates to the way in which the reallocation or load sharing is performed. By reallocating or moving users of a particular kind, e.g., single slot users, and avoiding reallocation of users of other particular kinds, the load sharing and reallocation are further improved.
