Method and apparatus for using a MAC protocol for broadcast

#Wireless communication systems are widely deployed to provide various types of communication content, such as, voice, media, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth and transmit power). Examples of such multiple-access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, 3GPP LTE systems, and orthogonal frequency division multiple access (OFDMA) systems.

#Generally, a wireless multiple-access communication system can concurrently support communication for multiple wireless terminals. Each terminal communicates with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to a communication link from base stations to terminals, and the reverse link (or uplink) refers to a communication link from terminals to base stations. This communication link may be established via one or more of single-in-single-out (SISO), multiple-in-single-out (MISO) or multiple-in-multiple-out (MIMO) systems.

#A wireless communication system can also be employed to provide various types of services. These services include point-to-point services, or dedicated services such as voice and packet data, whereby data is transmitted from a transmission source (e.g., a base station) to a specific recipient terminal such as in cellular telephony or Internet communications. In addition to these services, several providers have launched mobile multimedia services closely resembling traditional broadcast services such as radio, television etc. Such services push content aggregated into channels to subscribers. In some cases, the content may be taken from, for example, existing TV channels or it may be other special content.

#FIG. 1 is an illustration of a wireless multiple-access communication system in accordance with various aspects.

#FIG. 2 is a block diagram of an embodiment of a transmitter system and a receiver system in a MIMO system.

#FIG. 3A relates to an aspect associated with indexing of subbands employed for BCMCS in a UMB system.

#Various embodiments are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiment(s) may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

#As used in this application, the word “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete fashion.

#Additionally, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
