Abstract
A method of communicating with a transceiver (120). In one arrangement, the method of communicating with the transceiver can be performed in a systemless group environment. Synchronization information (150) can be received from a mobile transceiver (110) and used to synchronize to the mobile transceiver. The synchronization information can include a timing offset and a frequency offset. Synchronization can be maintained until a predetermined condition is met, for example, a predetermined amount of group inactivity.
