Title:
SDMA ACCESS CODEBOOK CONSTRUCTING METHOD AND APPARATUS THEREOF AND SCHEDULING METHOD AND APPARATUS AND SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/049366
Kind Code:
A1
Abstract:
A SDMA access codebook constructing method includes: setting two 4Œ4
base matrixes B1 and B2, for generating clusters of a SDMA
access codebook; generating a cluster I by using any two rows of the base matrix
B1, which are used as a generating base, generating a cluster II by using
the other two rows of the base matrix B1, which are used as a generating
base, and using the cluster I and the cluster II as a first pair of clusters; generating
a cluster I by using any two rows of the base matrix B2, which are used
as a generating base, generating a cluster II by using the other two rows of the
base matrix B2, which are used as a generating base, and using the cluster
I and the cluster II as a second pair of clusters; and forming a Part2 of the SDMA
access codebook by using the first pair of clusters and the second pair of clusters,
and then forming the SDMA access codebook by using the Part2. The present invention
also provides a SDMA access codebook scheduling method. The present invention
improves the utilization rate of the spectrum, and thereby increases the system
throughput according to above technical schemes.
