    Abstract: An apparatus and method provides for controlling communications from multiple base stations to a mobile station in a communication system. A mobile station transmitter transmits from the mobile station channel quality indicator data of a first base station. The data is covered with Walsh code assigned to the first base station. A base station receiver receives the transmission of the channel quality indicator data of the first base station. The mobile station transmitter punctures the transmission of the channel quality indicator data of the first base station with null channel quality indicator data, and covers the null channel quality data with Walsh code assigned to a second base station of the multiple base stations to indicate a desire to switch a source of transmission of traffic data from the first base station to the second base station.

    Abstract: A method of decoding in a wireless receiver, a wireless transmission from a predefined user, the method comprising: receiving a wireless transmission signal (r(m)); determining a one or more interfering spreading codes (si(m)) contributing to the received wireless transmission signal (r(m)); estimating a one or more interferer symbols ({circumflex over (b)}i(m)) from the received wireless transmission signal (r(m)) and the or each interfering spreading codes (si(m)); calculating a one or more scaling factors (Pi(m)) at which the or each of the interferer symbols ({circumflex over (b)}i(m)) was originally transmitted; simulating an interference signal i(m) in the received wireless transmission signal (r(m)); removing the simulated interference signal i(m) from the received wireless transmission signal (r(m)) to produce a processed wireless signal (o(m)); and estimating a one or more symbols {circumflex over (b)}(m) transmitted by the predefined user in the processed wireless signal (o(m)).

    Abstract: In a CDMA system (100), two chip rates in a TDD cell are supported by: transmitting signals in the system in a frame (400) having a plurality of timeslots; operating at least a first one (0-8) of the plurality of timeslots in the frame at a lower chip rate; and operating at least a second one (9-14) of the plurality of timeslots in the frame at a higher chip rate. This provides the following advantages: provides backwards compatibility of a network including higher chip rate functionality with existing lower chip rate user equipment; allows greater network capacity during the transition phase from a low chip rate network to a high chip rate network; and allows a network operator with a high chip rate network to provide service to roaming users from low chip rate networks.

    Abstract: A receiver employs low-rate processing to synthesize the effect of high-rate interference in a received multi-rate signal. Each high-rate subchannel is analyzed on its low-rate descendents to produce symbol estimates for each low-rate symbol interval. The symbol estimates are applied to low-rate descendent subchannels, which are then combined to synthesize the effects of the high-rate interference. An interference canceller processes the synthesized interference with the received signal for producing an interference-cancelled signal. Alternatively, analogous steps may be applied at high-rate to analyze, synthesize, and cancel the effects of low-rate interference in a multi-rate signal.
