Abstract
A method of transmitting data in a multiple antenna system includes transmitting a precoding matrix index (PMI) of a first user through a control channel for the first user, and transmitting the PMI of the first user and a PMI of a second user through a data channel for the first user. Effective data decoding is possible regardless of whether radio resources to be allocated to multiple users are partially or entirely allocated to the users.
Claims8
A method of transmitting data in a multiple antenna system, the method comprising:
- transmitting a precoding matrix index (PMI) of a first user through a control channel for the first user;
- and
- transmitting the PMI of the first user and a PMI of a second user through a data channel for the first user.
A method of transmitting data in a multiple antenna system, the method comprising:
- allocating radio resources to a plurality of users, wherein the radio resources are paired so that the radio resources partially or entirely overlap with each other;
- transmitting a PMI of one of the plurality of users through a first channel;
- and
- transmitting PMIs of the plurality of users through a second channel in the radio resources after multiplexing the PMIs of the plurality of users.
A method for processing data in a multiple antenna system, the method comprising:
- receiving a PMI through a control channel;
- receiving a multiplexed PMI through a data channel, wherein the PMI and a PMI of different user are multiplexed in the multiplexed PMI, and a radio resource for the data channel is partially or entirely shared with the different user;
- de-multiplexing the PMI and the PMI of different user from the multiplexed PMI on the data channel by using the PMI on the control channel;
- and
- reproducing data on the data channel by using the de-multiplexed PMI.
