Multi-media broadcast and multicast service (MBMS) in a wireless communications system
First Claim
1. In a wireless communication system, a method for processing data for transmission to a plurality of terminals, comprising:
- providing a plurality of frames of information bits to a buffer implementing a matrix, wherein the frames may have variable rates and each frame may include a particular number of information bits that is different from those of other frames provided to the matrix;
padding the matrix with padding bits based on a particular padding scheme; and
coding the plurality of frames of information bits based on a particular code to provide a plurality of parity bits, and wherein the frames of information bits and the parity bits are transmitted to the plurality of terminals;
wherein one frame is provided to each row of the matrix, and wherein an unused portion of each row is padded with padding bits;
wherein each row of the matrix has a size M corresponding to less than a maximum number of information bits expected to be received for a frame.

Abstract
Techniques to implement MBMS services in a wireless communication system. In one aspect, a method is provided for processing data for transmission to a plurality of terminals. Frames of information bits (which may have variable rates) are provided to a buffer implementing a matrix. The matrix is padded with padding bits based on a particular padding scheme to support variable frame rates. The frames are then coded based on a particular block code to provide parity bits. The frame of information bits and the parity bits are then transmitted to the terminals. In another aspect, a method is provided for controlling the transmit power of a data transmission to a plurality of terminals. In accordance with the method, TPC streams are received from the terminals and processed to obtain a stream of joint power control commands used to adjust the transmit power of the data transmission.
