Abstract
A method for transmitting feedback information via a Spatial Rank Index (SRI) channel includes determining, at an access terminal, a value of a spatial rank index and transmitting, from the access terminal through the SRI channel, feedback information indicating the determined value of the spatial rank index according to a prescribed coding. The codeword of the prescribed coding is one of: (0,0,0,0,0,0,0,0), (1,0,1,0,1,1,0,1), (0,1,1,1,0,0,1,1), or (1,1,0,1,1,1,1,0).
Claims11
A method for transmitting feedback information via a Spatial Rank Index (SRI) channel, the method comprising:
- determining, at an access terminal, a value of a spatial rank index;
- transmitting, from the access terminal through the SRI channel, feedback information indicating the determined value of the spatial rank index according to a prescribed coding,
- wherein a codeword of the prescribed coding is one of:
- (0,0,0,0,0,0,0,0),
- (1,0,1,0,1,1,0,1),
- (0,1,1,1,0,0,1,1), or (1,1,0,1,1,1,1,0).
A method for generating/transmitting a codeword, the method comprising:
- determining, at an access terminal, information regarding a value of a spatial rank;
- and
- generating, at the access terminal, the codeword to represent the determined information, the generating comprising combining a first codeword of a (3, 2) simplex code and a second codeword of a (5, 2) shortened Hamming code.
An access terminal for transmitting feedback information via a Spatial Rank Index (SRI) channel, the access terminal comprising:
- a controller configured to determine a value of a spatial rank index;
- a transmitter configured to transmit feedback information via the SRI channel, wherein the feedback information indicates the determined value of the spatial rank index according to a prescribed coding, and
- wherein a codeword of the prescribed coding is one of:
- (0,0,0,0,0,0,0,0),
- (1,0,1,0,1,1,0,1),
- (0,1,1,1,0,0,1,1), or
- (1,1,0,1,1,1,1,0).
