Shifted training sequences in a communications system
First Claim
1. A method comprising:
- selecting a training sequence from a set of training sequences;
receiving a shift indicator, the shift indicator indicating a number of symbols the training sequence is to be shifted;
generating a shifted training sequence by shifting the selected training sequence by the number indicated by the received shift indicator;
using the shifted training sequence for communication with a first transceiver on a communications channel.

Abstract
Embodiments of the present invention can be used to select a training sequence used by a base station and a user terminal for communications. In one embodiment, selecting the training sequence to use includes first selecting a training sequence from a set of training sequences. Then, a shift indicator is received, the shift indicator indicating a number of symbols the training sequence is to be shifted. A shifted training sequence is generated by shifting the selected training sequence by the number indicated by the received shift indicator, and the shifted training sequence is used for communication with a first transceiver on a communications channel. In another embodiment, a shift indicator indicating a number of symbols a training sequence is to be shifted is first selected, and then used to generate a shifted training sequence by shifting the training sequence by the number of symbols indicated by the selected shift indicator. The shifted training sequence is then used for communicating with a transceiver on a communications channel.
