A User Equipment and an information processing system are also provided.
1. An information processing method, comprising:
receiving, by a user equipment (UE), a Precoding Control Indication (PCI);
determining, by the UE, a target PCI according to the received PCI;
determining, by the UE, a weighting factor corresponding to the target PCI; and
applying, by the UE, the weighting factor to send data in an uplink closed-loop transmit diversity manner;
wherein the determining, by the UE, the target PCI according to the received PCI comprises:
if the received PCI comprises multiple PCIs sent by all or part of cells from a serving Enhanced Dedicated Channel (E-DCH) radio link set of the UE, determining, by the UE, a PCI combined from the multiple PCIs sent by all or part of the cells from the serving E-DCH radio link set of the UE as the target PCI, wherein the multiple PCIs are generated by a NodeB controlling the cells from the serving E-DCH radio link set of the UE with a same PCI value.
2. The method according to claim 1 , wherein after the determining, by the UE, the target PCI according to the received PCI, the method further comprises:
sending, by the UE, the target PCI to a NodeB controlling all or part of the cells in an E-DCH active set of the UE.
3. The method according to claim 1 , wherein the PCI is received by the UE when the UE is in a soft handover process.
4. The method according to claim 1 , wherein the applying, by the UE, the weighting factor comprises:
weighting, by the UE, a data block according to the weighting factor.
5. The method according to claim 4 , wherein the method further comprises:
sending, by the UE, output of the process of weighting the data block in the uplink closed-loop transmit diversity manner.
6. The method according to claim 1 , wherein the weighting factor corresponding to the target PCI is determined according to the target PCI and a mapping of a weighting factor and a PCI, the mapping of the weighting factor and the PCI are stored by the UE.
7. The method according to claim 1 , wherein a manner of combination of the received PCI is soft combination.
8. The method according to claim 1 , wherein the PCI is received by the UE periodically.
9. A User Equipment (UE), comprising:
a receiver, configured to receive a Precoding Control Indication (PCI); and
a processor, configured to determine a target PCI according to the PCI received by the receiver, determine a weighting factor corresponding to the target PCI, and apply the weighting factor to send data in an uplink closed-loop transmit diversity manner;
wherein the determining the target PCI comprises:
if the PCI received by the receiver comprises multiple PCIs sent by all or part of cells from a serving Enhanced Dedicated Channel (E-DCH) radio link set of the UE, determining a PCI combined from the multiple PCIs sent by all or part of the cells from the serving E-DCH radio link set of the UE as the target PCI, wherein the multiple PCIs are generated by a NodeB controlling the cells from the serving E-DCH radio link set of the UE with a same PCI value.
10. The UE according to claim 9 , further comprising:
a sender, configured to send the target PCI determined by the processor to a NodeB controlling all or part of the cells in an E-DCH active set of the UE.
11. The UE according to claim 9 , wherein the receiver is configured to receive the PCI when the UE is in a soft handover process.
12. The UE according to claim 9 , wherein the processor is configured to weight a data block according to the weighting factor.
13. The UE according to claim 12 , the UE further comprising:
a sender, configured to send output of the process of weighting the data block in the uplink closed-loop transmit diversity manner.
14. The UE according to claim 9 , wherein the processor is configured to determine the weighting factor corresponding to the target PCI according to the target PCI and a mapping of a weighting factor and a PCI; and
the UE further comprising:
a memory, configured to store the mapping of the weighting factor and the PCI.
15. The UE according to claim 9 , wherein the processor is further configured to combine the PCI received by the receiver in a manner of soft combination.
16. The UE according to claim 9 , wherein the receiver is configured to receive the PCI periodically.
17. The UE according to claim 9 , wherein the processor is further configured to determine whether the PCI received by the receiver comprises the multiple PCIs sent by all or part of the cells from the serving E-DCH radio link set of the UE.
18. A system, comprising a User Equipment (UE) connected to a NodeB in a communicable mode, wherein:
the UE is configured to receive a Precoding Control Indication (PCI) from the NodeB, determine a target PCI according to the received PCI, determine a weighting factor corresponding to the target PCI, and apply the weighting factor to send data in an uplink closed-loop transmit diversity manner;
wherein the determining the target PCI comprises
if the received PCI comprises multiple PCIs sent by all or part of cells from a serving Enhanced Dedicated Channel (E-DCH) radio link set, determining a PCI combined from the multiple PCIs sent by all or part of the cells from the serving E-DCH radio link set of the UE as the target PCI, wherein the multiple PCIs are generated by a NodeB controlling the cells from the serving E-DCH radio link set of the UE with a same PCI value.
