A system and method for accommodating mobile station synchronization to neighbor cells in a mobile communication system. At least one available frame is utilized as a search window in an uplink data transfer multiframe for receiving neighboring cell synchronization information. At least one transmit time slot in a frame adjacent to the available frame in the uplink data transfer multiframe is surrendered to extend the search window. The neighboring cell synchronization information may then be contiguously received via the extended search window.

System and method for extending neighboring cell search window

Multiple transport channels () are multiplexed and transmitted in a single physical channel. A code (TFCI) is added to the transport channel data flows to indicate which processing schemes, from a set of available schemes, are being employed and the resultant blocks are interleaved. The depth of the interleaving is set in dependence on the transmission time intervals associated with the schemes in the set of processing schemes.

Transmitting interleaved multiple data flows

A method of generating a received signal quality signal in a communication system, the method comprising: receiving a signal from a physical channel, extracting a transport channel format combination indicator from the received signal, processing one or more transport channel signals, contained in the received signal, in accordance with the extracted transport channel format combination indicator, said processing including at least channel decoding, and generating a received signal quality signal in dependence on the quality of the or each transport channel signal prior to channel decoding.

Received signal quality determination

This invention discloses improved single antenna interference cancellation (SAIC) receivers utilizing joint channel estimation for suppression of interference of co-channel signals. This invention describes the technique to perform joint channel estimation for either synchronous or asynchronous co-channel signals without a prior knowledge of the interfering training sequence or its timing position. The invented joint channel estimation can require initial detection of the desired signal and can be implemented as a multistage equalization structure.
