Embodiment Construction

[0027] figure 1 A wireless system is shown that combines traditional cellular services with so-called hotspot services. A single operator can provide both services within the coverage area of ​​its PLMN (Public Land Mobile Network), providing hotspot coverage through several unlicensed frequency bands and cellular coverage through licensed frequency bands. It can be seen from the figure that several hotspot areas 130 using unlicensed spectrum may overlap with the cellular coverage of the macro cell 110 and may overlap with each other. Hotspot coverage may be provided by so-called micro base stations 140 with low transmit power consistent with government regulations for operation in unlicensed spectrum. Cellular coverage may be provided by conventional base stations or "macro" base stations, such as base station 120 illustrated. The mobile terminal 150 may be able to obtain service from the hotspot 130 or from the macro cell 110 according to the location of the terminal.

Abstract

Parameters that define the frequency raster points to be used in an unlicensed band are used to support operation of wireless devices in both licensed and unlicensed frequency bands. Corresponding signaling messages are used to exchange information regarding the device's capabilities, preferences, transmission power, etc. In one method, implemented in a wireless communication device (410) configured to operate in at least first and second frequency bands, a radio access network is accessed (510), using a first radio access mode and the first frequency band. The method further comprises transmitting (520) frequency raster data to the radio access network, wherein the frequency raster data corresponds to the second band, indicates a tuning capability of the wireless communication device (410), and comprises at least a first frequency index and a granularity indicator. Methods and apparatus for maintaining a database of access point capabilities in unlicensed bands are also disclosed.

Description

technical field [0001] The present invention relates to wireless communication systems and wireless communication devices, and more particularly, to techniques for controlling the operation of wireless devices capable of operating in both licensed and unlicensed spectrum using the same or different radio access technologies. Background technique [0002] Currently, there are a large variety of wireless mobile devices (including mobile phones, wireless personal digital assistants, wireless-capable laptop computers, etc.) Incoming connections enable access to a wide range of different services. As a result, the range of capabilities of mobile devices is quite wide. For example, in the 3rd Generation Partnership Project (3GPP) specification for a wireless system called Long Term Evolution (LTE) (Release 8 or later), a compatible mobile terminal (referred to in 3GPP terminology as User Equipment or UE ) are grouped into five categories that are only relevant to their LTE uplin...
