Multi-media broadcast and multicast service (MBMS) in a wireless communication system
First Claim
1. In a wireless communication system, a method for controlling transmit power of a data transmission to a plurality of terminals, comprising:
- receiving a plurality of uplink transmit power control (TPC) streams from the plurality of terminals;
processing the plurality of uplink TPC streams to obtain a stream of joint power control commands for the data transmission; and
adjusting the transmit power of the data transmission based on the stream of joint power control commands.

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.
