Abstract: A "hybrid" ARQ system within a multiple access wireless communications environment is provided for-recombining ARQ retransmission signals with information obtained from corresponding previously failed transmissions of the same signal which had been sent and received within the air interface. Forward Error Correction (FEC) is implemented within an ARQ environment by using whatever acquired information has been previously obtained from RAKE processed transmitted and retransmitted signals and trying to correct the information by combining the signals and without retransmission.

Forward Error Correction (FEC) is implemented within an ARQ environment by using whatever acquired information has been previously obtained from Rake processed transmitted and retransmitted signals and trying to correct the information by combining the signals and without retransmission. In a second preferred embodiment of the present invention, Turbo encoded transmitted information is only partially re-transmitted by the transmitter in order to achieve a successful transmission.

Abstract: An integrated communication system supporting multiple TDMA or TDD communication protocols whereby both protocols are supported within the same geographic region. Each protocol defines time frames and/or time slots of a different duration, from which is derived a composite time frame having a predefined timing structure. A first base station unit communicates in a first set of time slots of the composite time frame according to a first TDMA or TDD protocol, and a second base station unit (which may be collocated with the first base station unit) communicates in a second set of time slots of the composite time frame according to a second TDMA or TDD protocol. Coordinating electronics (such as a GPS receiver in one or both base station units) are provided so as to prevent collisions between communications occurring between each base station unit and its respective users. In a particular embodiment, a first protocol is a GSM protocol, and a second protocol is a TDD protocol utilizing spread spectrum techniques.
