摘要： A method and apparatus for enabling a radio to track channel timing and support channel scanning. A non-leading radio operating (610) on a communications channel, determines a diffusion period during which channel timing is to be propagated from a leading radio to non-leading radios operating on the communications channel. The non-leading radio implements (620) a first scanning pattern during the diffusion period to scan a CT designated channel for a control timing message with a timing signal sent from the leading radio. The first scanning pattern involves scanning the CT designated channel during every other scan interval and scanning non-priority channels and priority channels during scan intervals not used on the CT designated channel.

摘要： To perform channel inspection, a wireless communication device conducts a full inspection on a first channel carrying a first signal that includes: determining (204) a location of a first synchronization message; and determining (206) whether the first signal is of interest. Upon determining that the first signal is not of interest, the first channel is marked, wherein the marking includes remembering (210) the location of the first synchronization message. The device leaves (212) the first channel and determines (212) an expected location of a second synchronization message on the first channel based on the location of the first synchronization message. Upon returning (214) to the first channel which carries a second signal, the communication device conduct a partial inspection that includes: detecting (216) whether the second synchronization message is present at the expected location, wherein the presence of the second synchronization message indicates that the second signal is not of interest.

摘要： A method for detecting a channel in a mixed-mode communications system is presented. The channel contains a primary synchronization pattern in a predetermined location within the channel. The primary synchronization pattern is compared against different predetermined channel synchronization patterns to detect a channel. Upon detection of the channel, a look-back channel detector confirms the existence of the channel by using the location of the primary synchronization pattern. Detection and confirmation of the channel may be employed simultaneously to each channel of a multiple-channel direct mode of operation signal. Audio holes may be eliminated in a 2:1 TDMA direct mode operation where both time slots contain signals from two different originating communication devices and the signals have different priority.
