Methods providing offset values defining differences between MIMO data streams and related controllers and wireless terminals

摘要

A method of communicating with a wireless terminal may include providing first information 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 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 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, and the offset value may be transmitted to the wireless terminal.

1. A method of communicating with a wireless terminal, the method comprising:
providing first information 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; providing second information 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, wherein the first and second sectors are different and the first and second antenna arrays are different; generating an offset value responsive to the first information and the second information, wherein the offset value defines a difference between the first and second MIMO data streams for a second transmission time interval; and transmitting the offset value to the wireless terminal, wherein generating the offset value comprises generating a first offset value responsive to the first information and generating a second offset value responsive to the second information, wherein the first offset value defines a first difference between data rates of the first and second MIMO data streams for the second transmission time interval after the first transmission time interval, wherein the second offset value defines a second difference between data rates of the first and second MIMO data streams for the second transmission time interval, and wherein transmitting the offset value comprises transmitting the first and second offset values to the wireless terminal.
