Methods and apparatus for reporting and/or using control information
First Claim
1. A method of operating a base station in a communications system including a wireless terminal that communicates control information reports, the method comprising:
- receiving a first report of a particular type according to a first reporting format from said wireless terminal operating in a first mode of operation, said first reporting format communicating a signal-to-noise-ratio value without a preferred link indicator; and
receiving a second report of the same particular type according to a second reporting format from said wireless terminal operating in a second mode of operation, said second reporting format being different from said first reporting format, said second reporting format communicating both a signal-to-noise ratio value and a preferred link indicator value,wherein said first reporting format and said second reporting format each encode information into the same number of information bits.

Abstract
A wireless communications system supports wireless connections between base station sector attachment points and wireless terminals. Individual wireless connections correspond to one of a downlink-macrodiversity mode of operation and a downlink non-macrodiversity mode of operation. A wireless terminal has, for each of its current connections, a base station assigned dedicated control channel for communicating uplink control information reports. The uplink control information reports include downlink signal-to-noise ratio reports based on measured received pilot channel signals. If a connection corresponds to a macrodiversity mode of operation, a reporting format for the SNR report is used which reports (i) an SNR value and (ii) an indication as to whether or not the connection is considered a preferred connection by the wireless terminal. If a connection corresponds to a non-macrodiversity mode of operation, a reporting format for the SNR report is used which reports an SNR value.
