PROVIDING OFFSET VALUES DEFINING DIFFERENCES BETWEEN MIMO DATA STREAMS

摘要

A method of communicating with a wireless terminal may include providing first information (e.g. SIR or rate) responsive to receiving first and second multiple input multiple output (MIMO) data streams from the wireless terminal through a first antenna array of a first sector during a first transmission time interval. Second information (e.g. SIR or rate) may be provided responsive to receiving the first and second MIMO data streams from the wireless terminal through a second antenna array of a second sector during the first transmission time interval TTI with the first and second sectors being different and the first and second antenna arrays being different. An offset value may be generated responsive to the first information and/or the second information with the offset value defining a difference between the first and second MIMO data streams for a second transmission time interval (e.g. difference between data rates of first and second MIMO data streams) and the offset value may be transmitted to the wireless terminal.
