Abstract: The usage capacity of a base station operating in four-branch receive diversity mode is limited to a given number of channel resources, where each channel resource corresponds to an active user. In two-branch receive diversity mode, approximately twice as many channel resources are available, but the receiver sensitivity is less than with four-branch mode. Thus, four-branch mode provides better coverage but with less usage capacity. A base station is operated in four-branch mode to provide the best coverage while usage is low. When the number of users reaches a first threshold, prior to reaching the maximum number of users, the base station transitions to two-branch mode to accommodate an anticipated increase of users above the four-branch capacity, although with reduced coverage. When usage then falls below a second threshold, the base station transitions back to four-branch mode, again providing better coverage.
