Abstract: In order to establish routing to/from a base station within a hybrid-cellular network, each network element is assigned a “class” based on a received signal strength of the base station. Each network element is allowed to choose a network element of lower class for relaying information to the base station.

Abstract: The present invention provides linear MMSE equalization with parallel interference cancellation for symbol determination in a forward link of a CDMA communication system which has a plurality of code channels in use. Use of the linear MMSE equalization with parallel interference cancellation of the present invention provides significantly increased performance. The preferred method linearly filters a received signal to form a first filtered signal (410), despreads and demodulates the first filtered signal (415, 420) and provides a plurality of symbol estimates for all corresponding code channels (430). An estimated transmitted signal is generated from the plurality of symbol estimates (435), and with a channel estimate (405), an estimated received signal is generated (440).

Abstract: Communications sourced by a remote unit (14) that is already within reception range of a base site (10) can nevertheless be further facilitated through allocation of one or more relay resources (15, 16). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.

Abstract: A communication system employs a HARQ-type retransmission scheme. Bits (701) received on a first transmission are stored and combined with the bits received on later transmissions thereby increasing the likelihood of a correct decoding on later transmissions. Similarly the bits received on the second or later transmissions are stored for combining with subsequent received bits. Specific information needed at the receiver is identified and requested from the transmitter. More particularly, information that is retransmitted in a second or later transmission in the HARQ scheme is determined from a reliability of individual constituent bits in the mother codeword or from an overall reliability of the received codeword. Based on these reliability metrics, the most unreliable set of the constituent bits are requested or, in the alternative, a specific number of constituent bits is requested.
