Abstract: A wireless communication network (20) includes a power control technique that includes repeating an erasure indicator bit in a transmission from a mobile station (22) to a base station (24, 30, 36). The repeated erasure indicator bit is transmitted on the uplink to each base station. The base station then uses the majority rule of those repeated erasure indicator bits to adjust its transmit power. It results in a desired power control command corresponding to the quality of a downlink between a base station (24, 30, 36) and the mobile station (22). A disclosed example includes using the repeated error indicator bit for deciding whether a recent frame should be considered an erasure. If so, the base station increases power on the downlink forward channel. If not, the base station decreases the transmit power on the downlink forward channel. A disclosed example includes alternative power control adjustment techniques, depending on the recent history of the quality of the downlink.

Abstract: An allocation of M network allocations (e.g., physical resource blocks) among N users is by a signaling word having a maximum number of bits given by ceil(M*log 2(N+1)). The signaling word is sent to users, who determine the resources allocated to them from the signaling word. In an embodiment, the signaling word is a series of binary index numbers, each index number assigned to one user, and the network allocations are stored in a known order in a list. The position of the index number in the signaling word, in view of the list, gives the network allocation to that user index number. For example, a user assigned the index number at the kth position in the signaling word is allocated the network allocation at a corresponding kth position of the stored list. This uses fewer signaling bits than the known prior art disclosed herein.

Abstract: The present invention relates to a method for controlling a data rate for a forward data service in a CDMA 2000-1x system. Conventionally, the data rate from a base station to a mobile station is constant regardless of the wireless environment of the mobile station. As such, resources used in the base station for communication with the mobile station may be wasted if the data throughput is low due to the poor wireless environment. The present invention, however, resolves this problem by varying the data rate according to Energy of Carriers/Interference of Others' (Ec/Io) of the data, which indicates the wireless environment of the mobile station. With the present invention, the resources in a base station, which would be wasted for communication with a mobile station in a poor wireless environment, can be used for other mobile stations. Thus, the resources of the overall CDMA 2000-1x system can be used efficiently.
