Abstract:
The present invention provides a method for receiving broadcast data in a system where broadcast data is transmitted on a plurality of frequencies. A user device monitors (302) a first frequency (108) for broadcast data to be transmitted on the first frequency. The device receives on the first frequency a notification of a broadcast data session which is to be sent on a second frequency (114) that is different from the first frequency. The device then determines a configuration associated with the second frequency and in accordance with receiving the broadcast data session and then configures (310) to receive the broadcast data session in accordance with the determined configuration. After receiving the broadcast data session, the device returns to monitoring the first frequency.
Abstract:
A method and apparatus for interrupting a transmission of a multicast signal includes a common channel selector (106) coupled to a receiver (102) to receive common channel information (116) therefrom. A repetition value calculator (108) receives measurement occasion information (118) from the common channel selector (106) to calculate a repetition factor (120). A system frame number comparator (110) determines if a channel measurement occasion (128) should be performed based on the repetition factor (120), a common identifier (124) and a largest common channel transmission time interval (122). The method and apparatus further includes a measurement occasion generator (112) coupled to the system frame number comparator (110), wherein if a measurement occasion is to be performed, a measurement occasion command signal (126) is provided to the measurement occasion generator (112) and the measurement occasion generator generates the channel measurement occasion (128).
Abstract:
A communication system (300, 1000) supports Hybrid Automatic Repeat Request (H-ARQ), Adaptive Modulation and Coding (AMC), active set handoff, and scheduling functions in a distributed fashion by allowing a mobile station (MS) (1014) to signal control information corresponding to an enhanced reverse link transmission to Active Set base transceiver stations (BTSs) (301, 303, 304) and by allowing the BTSs to perform control functions (314, 316, 318) that were supported by an radio network controller (RNC) in the prior art. The communication system allows time and SIR-based H-ARQ flush functions at the BTSs during soft handoff (SHO), provides a control channel structure to support scheduling, H-ARQ, AMC functions for an enhanced reverse link, or uplink, channel (414) in order to maximize throughput, and enables an MS in a SHO region to choose a scheduling assignment corresponding to a best TFRI out of multiple assignments it receives from multiple active set BTSs.
Abstract:
A Dedicated Physical Location Channel (DPLCH) is utilized by a mobile station (913) to support subscriber location functions. The DPLCH is spread by an Orthogonal Variable Spreading Factor (OVSF) code CL (502) of length 256 which is distinct from those OVSF codes assigned to other channels utilized by the mobile station (913). When a power-up function (PUF) is received by the mobile station (913), the DPLCH sub-channel amplitude is then modified relative to the other channels being utilized by the mobile station (913) using gain module GL (503) prior to combination (504) with the other channels.

Abstract:
A method and apparatus for jointly decoding a first and second message is disclosed. The signaling scenario illustrated by FIG. 1 and using the codeword properties defined herein, the various embodiments may combine multiple messages under the hypothesis that the value of a message portion corresponding any subsequent observed transmission is different. Accordingly a first buffer may store the first observed message frame (509) and a second buffer may sum the LLR's of subsequent observed frames (513). In the embodiments disclosed, two decoding hypotheses are required only; a first where the two buffers are combined directly (513) and a second where the difference codeword bit LLR's of the first buffer (509) are inverted before combining with those of the second buffer (519). A maximum of N transmissions is allowed by the receiver (523), after which a decoding failure is declared.
