    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: The invention provides a system and method for testing signal transmission quality within a digital communication system and may be incorporated within a digital cellular communication system in which information is exchanged over spread spectrum communication channels. A test sequence of digital data transmitted over the communication channel is received at a receiving station, within which is also generated a replica of the test sequence of digital data. The accuracy of transmission over the communication channel is then determined by comparing the replica of the test sequence of digital data to the test sequence of data received over the communication channel. The invention allows the test sequence of digital data to be transmitted at one of a set of known data rates, with the received station being disposed to identify the data rate associated with each test sequence of digital data. In order to simulate the transmission of, for example, voice data, the system may be configured such that each test sequence of digital data is generated in accordance with a pseudorandom process.

    Abstract: A method and apparatus for providing orthogonal spot beams (14a, 14b), sectors (16a, 16b), and picocells (18). The transmissions can be made orthogonal by using orthogonal auxiliary pilots and different Walsh traffic channels in adjacent areas. In accordance with the IS-95 standard, the pilot signal is covered with the 64-chip Walsh sequence zero. The 64-chip all zeros Walsh sequence can be designated as P and the 64-chip all one sequence can be designated as M. In the present invention, additional pilot signals can be provided by concatenating 64-chip all zeros P and all ones M sequences. Thus, for two pilot signals, pilot Walsh sequences of PP and PM can be used. For four pilot signals, pilot Walsh sequences of PPPP, PMPM, PPMM, and PMMP can be used. The present invention can be extended such that any required number of pilot Walsh sequences can be generated by substituting each bit in an K-bit Walsh sequence with the 64-chip all zeros P or all ones M sequence depending on the value of that bit.

    Abstract: In a method for negotiating service configuration in a communication system having at least one dedicated channel which is not shared by communication devices in the communication system, a request message indicative of a proposed service configuration is generated in a service negotiator (20). The request message is multiplexed, in a multiplexer (22) coupled to the negotiator (20), with an information data signal to produce a multiplexed signal. The multiplexed signal is encoded in an encoder (24) interposed between the multiplexer (22) and a transmitter (26) in accordance with a service configuration selected by the service negotiator (20). The multiplexed and encoded signal is transmitted by the transmitter (26) over the dedicated channel. Received signals are decoded a decoder (16) interposed between a receiver (14) and a demultiplexer (18). A response message indicative of a response to the proposed service configuration is received by the receiver (14). A determination is made by the service negotiator (20) whether the response message is indicative of a mutually acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal in accordance with the proposed service configuration if the response message is indicative of an acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal with a universal default service configuration if the response message is not indicative of an acceptable service configuration.
