Synchronization signaling coordination for co-existence on a shared communication medium
First Claim
1. A communication method, comprising:
- selecting, at an access point, a common sequence, frequency, and time for a first synchronization signal that is coordinated with one or more other access points;
transmitting, from the access point, on a wireless communication medium shared by a plurality of radio access technology systems, the first synchronization signal in accordance with the common sequence, frequency, and time; and
transmitting, from the access point, on the wireless communication medium shared by the plurality of radio access technology systems, a second synchronization signal at a time that is offset from the first synchronization signal and in accordance with an individual sequence that is different from the common sequence of the first synchronization signal, wherein a sequence value is selected for the individual sequence that is outside of a set of values recognized by at least one access terminal configured to receive synchronization signals.

Abstract
Techniques for synchronization on a shared communication medium are disclosed. An access point may select, for example, a common sequence, frequency, and time for a first synchronization signal that is coordinated with one or more other access points. The access point may then transmit the first synchronization signal in accordance with the common sequence, frequency, and time. An access terminal may receive, from an access point, a first synchronization signal having a first sequence and a second synchronization signal having a second sequence. The access terminal may then determine an offset in time between the first synchronization signal and the second synchronization signal, and determine a cell identifier group associated with the access point based on the offset.
