Patent CA-2345732-A1 (CA)
Title: Load sharing for mcpa-equipped base stations
Inventor: JOHANSSON CHRISTER
IPC: H04B7/005
Filed: 1999-10-01
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.

Title: Radio communication systems
Inventor: WOOD STEVEN ANDREW
IPC: H04B1/7115
Filed: 2001-05-01
Abstract: A third generation general partnership program radio communication system or a universal mobile telephone system employs a wide band code division multiple access system. The codes in various incoming signals from different sources are identified by cross correlation using a code matched filter. A multiplexer, samples the signals from each of the P sources at P times the chip rate of the codes in the incoming signals. The mutliplexer time multiplexes the received signals and feeds them to single delay line consisting of N stages each having P elements. Each stage will thus store one sample firm each of the P sources. A selected element in each stage has an output which feeds a corresponding input of a code matched filter dot-product adder chain to enable a cross-correlation to be established for each incoming signal in turn.
