US 8,804,675 B2 · Method and apparatus for signaling in digital radio systems

Abstract

A method and apparatus for transmitting data are provided. In the method, data streams are mapped onto frames, a word is generated including information for receiving the data streams for a given frame, and parity bits are derived from the word for the given frame. The data is arranged in the frames. Each of the frames includes a preamble and a data section. The preamble and the data section are time-multiplexed. The data section includes at least a part of the data streams, and the preamble includes signaling information. The word is inserted in a preamble section of the given frame, and one of the parity bits is inserted in a preamble section of a prior frame preceding the given frame. A part of the word for the given frame is inserted within a data section of an earlier frame preceding the prior frame. The frames are then transmitted.

Dependent claims

A method of transmitting data including a plurality of data streams by a transmitter in a wireless communication system, the method comprising:

mapping a plurality of data streams onto a plurality of frames;
generating a signaling information word including information for receiving the plurality of data streams for a given frame;
deriving a plurality of parity bits from the signaling information word for the given frame;
arranging the data in the plurality of frames, each of the plurality of frames including a preamble section and a data section, the preamble section and the data section being time-multiplexed, the data section including parts of the plurality of data streams, and the preamble section including signaling information;
inserting the signaling information word in a preamble section of the given frame;
inserting at least one of the plurality of parity bits in a preamble section of a prior frame preceding the given frame;
inserting part of the signaling information word for the given frame within a data section of an earlier frame preceding the prior frame;
and
transmitting the plurality of frames.

6 more elements

A method of receiving data including a plurality of data streams by a receiver in a wireless communication system, the data being arranged in a plurality of frames, each of the plurality of frames including a preamble section and a data section, the preamble section and the data section being time-multiplexed, the data section carrying parts of the plurality of data streams, and the preamble section carrying signaling information, the preamble of a given frame including a signaling information word in a preamble section of the given frame, the signaling information word carrying signaling for assisting in reception of the plurality of data streams for the given frame, and a preamble section of a prior frame preceding the given frame including at least one of a plurality of parity bits derived from the signaling information word for the given frame, the method comprising:

receiving a part of the signaling information word for the given frame within the data section of an earlier frame, the earlier frame preceding the prior frame;
and
determining whether or not to receive the signaling information word for the given frame included in the preamble of the given frame and the at least one parity bit included in the preamble of the prior frame, based on information derived from the earlier frame.
