Methods and apparatus for power efficient broadcasting and communication systems

摘要

A method and apparatus for content multicasting and broadcasting and data unicasting in a broadband multicarrier wireless communication system. A base station is configured to transmit, and a mobile station is configured to receive, a sequence of consecutive frames. The frames comprise two types: frames containing time-frequency resources for content multicasting and broadcasting via a single frequency network, and frames containing time-frequency resources for data unicasting without the use of a single frequency network. The two types of frames are intermixed in accordance with an intermixing configuration pattern. The intermixing configuration pattern is indicated by a bit-map contained in a scheduling signal.

1. A receiving method for a mobile station in a multi-cell wireless system using a frame structure, each frame containing a plurality of orthogonal frequency division multiplexing (OFDM) symbols, the method comprising:
receiving a sequence of consecutive frames, the sequence of consecutive frames comprising a plurality of first frames and a plurality of second frames that are intermixed in accordance with an intermixing configuration pattern, each of the first frames containing time-frequency resources used for content multicasting or broadcasting (MB) via a single frequency network (SFN) that is comprised of base stations in multiple cells transmitting the same MB content using OFDM and employing a same time and frequency resource, and each of the second frames containing time-frequency resources used for data unicasting without the use of a SFN; receiving a scheduling signal containing a bit-map that indicates the intermixing configuration pattern of the received first and second frames by using “1” in the bit-map to represent a first frame and a “0” in the bit-map to represent a second frame, or a “1” in the bit-map to represent a first frame and a “0” in the bit-map to represent a second frame; and utilizing the received bit-map to identify the first and second frames.
