Embodiment 1

[0024] Embodiment 1, in the MIMO mode, the base station selects to use dual data stream transmission for the HS-DSCH channel, and makes the CCS of the two data streams the same. An indication method of a channelization code set in the present invention is as follows: figure 1 As shown, the method uses one or several bit combination states indicating O+P>16 of a single data stream to indicate the CCS combination of multiple data streams. refer to figure 1 , this embodiment includes the following steps:

[0025] Step s101, setting the corresponding relationship between the bit combination state and the CCS combination. In this embodiment, 8 kinds of bit combination states indicating single data stream P=8 and O>8 are used to indicate the CCS combination of double data streams, and each state corresponds to x ccs，1 、x ccs，2 ...x ccs，7 They are: 1110000, 1110001, 1110010, 1110011, 1110100, 1110101, 1110110 and 1110111. The corresponding relationship between the bit combinati...

Embodiment 2

[0036] Embodiment 2, in the MIMO mode, the base station selects to use dual data stream transmission for the HS-DSCH channel. An indication method of a channelization code set in the present invention is as follows: figure 2 As shown, the method uses one or several bit combination states indicating O+P>16 of a single data stream to indicate the CCS combination of multiple data streams.

[0037] refer to figure 2 , this embodiment includes the following steps:

Abstract

The invention discloses a channelized code collection indicating method. Under a multi-input multi-output mode, the invention uses one or more bit combination state(s) which can indicate that the summation of the channelized code multi-code number of the single-data current and the offset of the initially channelized code is more than 16, for indicating the CCS combination of the multi-data currents. The invention also discloses a channelized code collection information sending end which includes a channelized code collection indicating unit, and uses one or more bit combination state(s) which can indicate that the summation of the channelized code multi-code number of the single-data current and the offset of the initially channelized code is more than 16, for indicating the channelized code set combination of the multi-data currents. By using one or more bit combination state(s) which can indicate that the summation of the channelized code multi-code number of the single-data current and the offset of the initially channelized code is more than 16, for indicating the CCS combination of the multi-data currents, the invention provides more CCS combinations of the multi-data current.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for indicating a channelization code set and a sending end of channelization code set information. Background technique [0002] With the maturity and development of HSDPA (High-Speed ​​Downlink Packet Access) technology, its good application prospect and smooth evolution capability have attracted more and more attention. HSDPA is used to realize WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) network high-speed downlink data service, which can make the downlink data rate reach 8 ~ 10Mbps; MIMO (Multiple-Input Multiple-Out-put, multiple input Multi-output) technology HSDPA system, the data rate can reach 20Mbps. [0003] The MIMO system uses multiple antennas at the transmitting end and the receiving end at the same time, and achieves the purpose of improving spectrum efficiency by effectively utilizing multipath pro...
