1. A method of receiving information on a channel by a subscriber station, the method comprising:
- receiving a first set of frames of a first transmit buffer transmitted on the channel from a first cell, wherein the first set of frames includes a first portion of the information, and each frame of the first set of frames has been inner coded and outer coded;
receiving a second set of frames of a second transmit buffer transmitted on the channel from a second cell, wherein the second set of frames includes a second portion of the information, and each frame of the second set of frames has been inner coded and outer coded, the outer coding performed in the same manner as the outer coding of the first set of frames; and
determining duplicated frames of the received first set of frames and the received second set of frames according to an indication of a time-alignment of the first set of frames and the second set of frames.

Abstract
An outer decoder and an inner decoder encode a block of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. Time re-alignment of two transmissions of the same content from two base stations can mitigate the problem of duplicated frames. The user of the subscriber station can experience seamless service without repetition of content, even when handing over to a new cell while receiving a buffer of broadcast content.

8. A subscriber station for receiving information on a channel transmitted by a first cell and a second cell, the apparatus comprising:
-
a radio unit configured to receive a first set of frames of a first transmit buffer transmitted on the channel from a first cell, wherein the first set of frames includes a first portion of the content, and each frame of the first set of frames has been inner coded and outer coded; the radio unit further configured to receive a second set of frames of a second transmit buffer transmitted on the channel from the second cell, wherein the second set of frames includes a second portion of the content, and each frame of the second set of frames has been inner coded and outer coded, the outer coding performed in the same manner as the outer coding of the first set of frames; and a processing unit for determining duplicated frames of the received first set of frames and the received second set of frames according to an indication of a time-alignment of the first set of frames and the second set of frames. - View Dependent Claims (9, 10, 11, 12)

13. An apparatus for receiving information on a channel by a subscriber station, comprising:
-
means for receiving a first set of frames of a first transmit buffer transmitted on the channel from a first cell, wherein the first set of frames includes a first portion of the information, and each frame of the first set of frames has been inner coded and outer coded; means for receiving a second set of frames of a second transmit buffer transmitted on the channel from a second cell, wherein the second set of frames includes a second portion of the information, and each frame of the second set of frames has been inner coded and outer coded, the outer coding performed in the same manner as the outer coding of the first set of frames; and means for determining duplicated frames of the received first set of frames and the received second set of frames according to an indication of a time-alignment of the first set of frames and the second set of frames. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A computer-readable medium including computer-executable instructions encoded thereon for performing a method of receiving information on a channel by a subscriber station, the method comprising the steps of:
-
receiving a first set of frames of a first transmit buffer transmitted on the channel from a first cell, wherein the first set of frames includes a first portion of the information, and each frame of the first set of frames has been inner coded and outer coded; receiving a second set of frames of a second transmit buffer transmitted on the channel from a second cell, wherein the second set of frames includes a second portion of the information, and each frame of the second set of frames has been inner coded and outer coded, the outer coding performed in the same manner as the outer coding of the first set of frames; and determining duplicated frames of the received first set of frames and the received second set of frames according to an indication of a time-alignment of the first set of frames and the second set of frames.
