Channel quality reporting in a multi-antenna wireless communication system
In MU-MIMO scenarios, a receiving node (1000) provides feedback on a feedback channel to a transmitting node (1300) regarding a channel between the receiving and the transmitting nodes (1000, 1300). To reduce signaling overhead, a feedback channel structure, such as HS-DPCCH, is used in which the fields that carry feedback information are specifically agreed upon. For example, in uplink signaling in a 4-branch MIMO, it was agreed that two codewords be used for CQI reporting and to send all information in one subframe. This structure is valid when the preferred rank is 2, 3, or 4. But when the preferred rank is 1, the CQI information does not fill the two codewords. To address such issues, mechanisms to map such feedback information to completely fill the allocated space are proposed. Padding and repeating are examples of such mechanisms. |
