Abstract

Methods and devices for communicating in a communication system are described herein. One aspect of the subject matter described in the disclosure provides a method of communicating over one or more space time streams. The method includes transmitting a precoded portion of a first stream with a bandwidth of 1 MHz or less. The method further includes transmitting when there are at least two streams a precoded portion of a second stream with a cyclic shift delay relative to the first stream of 4 µs. The method further includes transmitting when there are at least three streams a precoded portion of a third stream with a cyclic shift delay relative to the first stream of 1 µs. The method further includes transmitting when there are at least four streams a precoded portion of a fourth stream with a cyclic shift delay relative to the first stream of 5 µs.
