Claim Text:
1. A method of communicating in a system including at least one first type of network device having a first transmit power and a first carrier frequency and at least one second type of network device having at least one of a second transmit power that is lower than the first transmit power and a second carrier frequency that is higher than the first carrier frequency, the second type of network device operating within a first coverage area of the first type of network device, wherein there is a selected plurality of cell codes dedicated exclusively for identifying only the second type of network device such that the selected plurality of cell codes are never used for identifying the first type of network device, wherein the first type of network device provides a neighbor list including at least some of the selected plurality of cell codes, the method comprising: broadcasting a first downlink channel of at least two downlink channels from the second type of network device, wherein the first downlink channel is a transitory broadcast channel that provides information to facilitate mobile station mobility between the first type of network device and the second type of network device; using one of the selected plurality of cell codes as a cell code for the first downlink channel such that a mobile station receiving the provided neighbor list from the first type of network device can detect the second type of network device as a candidate for communications with the mobile station based on the first downlink channel; broadcasting a second downlink channel of the at least two downlink channels, wherein the second downlink channel is used for communications within a cell of the second type of network device; using a second channel cell code that is distinct from the selected plurality of cell codes for the second downlink channel; and providing an indication of the second channel cell code to the mobile station on the first downlink channel to facilitate the mobile station communicating with the second type of network device on the second downlink channel using the second channel cell code.
