Multi-media broadcast and multicast service (MBMS) in a wireless communication system
First Claim
1. A method for broadcasting data to a plurality of terminals in a wireless communication system, comprising:
- determining a plurality of frames, in a time-division multiplexed (TDM) physical channel, to be used for broadcasting data to the plurality of terminals, wherein the data comprises point-to-multipoint communication service data for delivering user content;
processing data for transmission to the plurality of terminals; and
broadcasting the processed data on the plurality of frames in the TDM physical channel.

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.
