Abstract: The present invention makes it possible to increase a data rate between a transmitter and receiver using a multiple-input, multiple-output radio frequency channel. A multiple-stream, multiple-antenna receiver measures a composite channel between a multiple-antenna transmitter and a multiple-antenna receiver to produce a composite channel measurement. The receiver selects a plurality of antenna array weight sets for use in the multiple-antenna transmitter in response to the composite channel measurement, where each antenna array weight set is associated with one of multiple data streams. Information describing the plurality of antenna array weight sets for use in the multiple-antenna transmitter are then transmitted.

Abstract: In a telecommunication system (10) for providing multimedia broadcast services to many user equipments (40-45), a physical random access channel (39) is provided for uplink transmission of power control information from the user equipments to a radio site (30, 35). Based upon a comparison of signal-to-noise ratios (53) each particular user equipment sends (55) or inhibits from sending a power control signal to the radio site to which it is coupled. When the radio site of the telecommunication system detects a power control signal (73), the radio site adjusts the transmission power of a broadcast channel intended for reception by multiple user equipments (75) to be incrementally greater than the previous power (81). For lack of detection of a power control signal, adjusts the transmission power of a broadcast channel to be incrementally lower than the previous power.

Abstract: A mobile station (500) comprises a transceiver (513, 515) and a controller (503) coupled to the transceiver, and configured to utilize a plurality of modulation and coding schemes. The controller (503) is further configured to receive a request message specifying a signal-to-noise-and-interference ratio range for received signals, determine whether a signal-to-noise and interference ratio for signals received by said transceiver is within said signal-to-noise and interference ratio range, select a modulation and coding scheme, from said plurality of modulation and coding schemes, for receiving data based on said signal-to-noise and interference ratio for signals received by said transceiver, and transmit an indicator requesting said modulation and coding scheme.

Abstract: An apparatus is provided for use in a multi-channel digital transmitter and receiver. A filtering process is accomplished by conditioning portions of a digitized signal during digital signal processing by integrating, taking the difference of, and multiplying portions of the digitized signal. The filtering process may be used in conjunction with a receiving process to generate a digitized channel signal (166, 168, 170, 172) by conditioning (132, 134, 136, 138) the digitized signal (128) and subsequently Fourier transforming (148) the conditioned portions of the digitized signal. Alternatively, the filtering process may be used in conjunction with a transmitting process by inverse Fourier transforming (324) a plurality of digitized information signals (300, 302, 304, 306) to be transmitted, generating a composite digitized signal (352), and subsequently conditioning the composite digitized signal (358).

Abstract: A method and apparatus for providing adaptive bearer configuration for MBMS delivery is disclosed. A first aspect of the present disclosure is a method of operating a wireless infrastructure entity (103) wherein a common radio resource (303) is allocated for receiving a response from at least one mobile station (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105. If at least one mobile station (109) responds to the request, PTM transmission mode will be used for MBMS delivery within the given coverage area (105). If more than one mobile station (109) within the coverage area (105) responds to the request, then all the responses will be over the common radio resource (303). The total number of responses to the request message may be limited by providing a probability factor within the request message.

Abstract: Separate Radio Network Controllers (11 and 13) exchange neighboring cell information between one another. This information is used, in turn, to facilitate macrodiversity reception of multicast content. By one approach, a receiver node (16) receives this neighboring cell information which facilitates compatible reception of corresponding multicast content. The receiver node (16) uses differing synchronization techniques, depending upon whether or not the multicast content is sourced by base stations that share a common Radio Network Controller.

Abstract: A plurality of input signals are processed (75) using a Hadamard transform (52) to produce a combined Walsh covered parallel sequence which is sampled in time. The time samples are commutated (76) by a switch (53) or multiplexer to form a Walsh covered serial sequence. The Walsh covered serial sequence is then quadrature phase shift keyed (77) and transmitted (79).

Abstract: A method and apparatus for neighbor assisted combining for localized multicast services. User equipment (120) is sent a signal (730) indicating the relationship between cells with respect to serving cells (112) transmitting a common multicast transmission. At least a portion of the common multicast transmission is transmitted (740) on the same resource on each serving cell. A pilot signal is transmitted (750) on each serving cell, the pilot signal related to the at least a portion of the common multicast transmission on each serving cell. An interfering signal and a related pilot are transmitted (760) on at least one different cell (114) from the serving cells.
