Abstract
Methods and apparatus for processing and generating broadcast messages determined by a subband and OFDM symbols of frames in which signals are received. Overhead messages indicating resources used by broadcast messages in a wireless communication system are generated. Signals are received over a wireless system and broadcast messages are determined from the signals as designated by a subband and OFDM symbols of frames of an ultraframe in which signals are received.
Claims23
A method of processing broadcast messages received over a wireless channel, the method comprising:
- receiving a plurality of signals;
- determining which of the signals corresponds to at least one broadcast message designated by a subband and orthogonal frequency division multiplexing (OFDM) symbols of frames in which signals are received;
- and
- determining an order of a plurality of broadcast messages within an interlace of a physical layer frame, when the at least one broadcast message includes the plurality of broadcast messages in the same physical layer frame, wherein the order of the plurality of broadcast messages in the physical layer frame increases for each interlace of the physical layer frame, and wherein the physical layer frame that occurs earlier in time is numbered lower.
An apparatus for processing broadcast messages received over a wireless channel, the apparatus comprising:
- means for receiving a plurality of signals;
- means for determining which of the signals corresponds to at least one broadcast message designated by a subband and orthogonal frequency division multiplexing (OFDM) symbols of frames in which signals are received;
- and
- means for determining an order of a plurality of broadcast messages within an interlace of a physical layer frame, when the at least one broadcast message includes the plurality of broadcast messages in the same physical layer frame, wherein the order of the plurality of broadcast messages in the physical layer frame increases for each interlace of the physical layer frame, and wherein the physical layer frame that occurs earlier in time is numbered lower.
An apparatus for processing broadcast messages received over a wireless channel, the apparatus comprising:
- a receiver configured to receive a plurality of signals;
- and
- a processor configured to determine which of the signals corresponds to at least one broadcast message designated by a subband and orthogonal frequency division multiplexing (OFDM) symbols of frames in which signals are received, and configured to determine an order of a plurality of broadcast messages within an interlace of a physical layer frame, when the at least one broadcast message includes the plurality of broadcast messages in the same physical layer frame, wherein the order of the plurality of broadcast messages in the physical layer frame increases for each interlace of the physical layer frame, and wherein the physical layer frame that occurs earlier in time is numbered lower.
A non-transitory processor-readable medium including processor-executable instructions thereon for performing a method of processing broadcast messages received over a wireless channel, the method comprising the steps of:
- receiving a plurality of signals;
- determining which of the signals corresponds to at least one broadcast message designated by a subband and orthogonal frequency division multiplexing (OFDM) symbols of frames in which signals are received;
- and
- determining an order of a plurality of broadcast messages within an interlace of a physical layer frame, when the at least one broadcast message includes the plurality of broadcast messages in the same physical layer frame, wherein the order of the plurality of broadcast messages in the physical layer frame increases for each interlace of the physical layer frame, and wherein the physical layer frame that occurs earlier in time is numbered lower.
