Embodiment 1
[0023] Such as figure 1 As shown, it is a flow chart of a precoding instruction PCI coding method in a scenario where high-speed downlink packet access DC-HSDPA using dual-carrier technology and transmitting adaptive antenna array TxAA coexist in an embodiment of the present invention. The above method includes:
[0024] 101. Acquire PCI information of two carriers of DC-HSDPA.
[0025] Optionally, before acquiring the PCI information of the two carriers of DC-HSDPA, the above method may also include: receiving a high-speed shared control channel order (HS-SCCH order) sent by the network end, and triggering the above PCI according to the HS-SCCH order joint encoding. The two carriers here refer to the two carriers of DC-HSDPA. These two carriers may be adjacent carriers or non-adjacent carriers. One carrier can be defined as the primary carrier and the other as the secondary carrier.
[0026] 102. Jointly encode the PCI information of the above two DC-HSDPA carriers, and c...
Embodiment 2
[0031] The PCI information of the two DC-HSDPA carriers is jointly encoded, and carried in the PCI and CQI parts of the same carrier (in fact, it can also be carried in other parts, and the present invention is not limited thereto). The pre-encoding information of the PCI and CQI parts use a 0 a 1 a 2 a 3 a 4 a 5 a 6 a 7 a 8 Indicates that there are two mapping methods:
[0032] pci 0 , pci 1 Indicates the precoding factor of the main carrier;
[0033] pci' 0 , pci′ 1 Indicates the precoding factor of the secondary carrier.
[0034] Mapping method one:
[0035] (a 0 a 1 a 2 a 3 a 4 a 5 a 6 a 7 a 8 )=(pci 0 pci 1 cqi 0 cqi 1 cqi 2 cqi 3 cqi 4 pci' 0 pci' 1 )
[0036] Mapping method two:
[0037] (a 0 a 1 a 2 a 3 a 4 a 5 a 6 a 7 a 8 )=(pci 0 pci 1 pci' 0 pci' 1 cqi 0 cqi 1 cqi 2 cqi 3 cqi 4 )

Embodiment 3
[0046] Corresponding to the above method embodiment, such as figure 2 As shown, it is a schematic structural diagram of a precoding instruction PCI encoding device in a scenario where high-speed downlink packet access DC-HSDPA using dual-carrier technology and transmitting adaptive antenna array TxAA coexist in an embodiment of the present invention. The above-mentioned device 20 includes:
[0047] An acquisition unit 201, configured to acquire PCI information of two carriers of DC-HSDPA;
[0048] The encoding unit 202 is configured to jointly encode the PCI information of the above two DC-HSDPA carriers, and carry it on the subframe of the same HS-DPCCH;
[0049] The sending unit 203 is configured to send the subframe of the HS-DPCCH carrying the PCI information of the two carriers of the DC-HSDPA to the network side.
[0050] Such as image 3 As shown, it is a schematic structural diagram of a PCI encoding device in another scenario where DC-HSDPA and TxAA coexist accordi...
