    摘要: A method and apparatus for allocation of shared spectrum in a wireless communication system uses a radio frequency (RF) beacon signal that is transmitted between access points of the wireless communication system. The information content of the RF beacon signal includes an identifier of the access point that generated the signal, identifiers of clients of that access point; and identifiers of the communication channels assigned to those clients. The client identifier may include at least part of an Internet Protocol (IP) address of the client. Additionally the beacon signal may contain client attributes to enable negotiation of the sharing of available communication channels between access points and clients.

    摘要: During operation of a secondary communication system, cells (106) are formed by a plurality of localized nodes (104) to alert other nodes within the cell of frequencies which must be protected or otherwise avoided. All nodes within the cell monitor a differing subset of all frequencies available, and share information with respect to acceptable and protected frequencies with each other via low-power, short-range communication. Each node then forms a list of available channels for communication, and chooses a single node to report this information back to controller.

    摘要: The presence of the non-television transmission within a channel is used to indicate that secondary non-licensed usage of the channel is permitted. Specifically, if secondary users incorporate the means to identify the unique modulation signature of the secondary user, decoding of a beacon signal may not be necessary. With the above in mind, a radio will be prevented from transmitting within a frequency band when no transmission within the licensed spectrum is currently taking place; the licensee is currently transmitting on the spectrum (e.g., television transmissions are taking place utilizing the spectrum, or the radio cannot sense the presence of a data channel (beacon).

    摘要翻译: 通道内的非电视传输的存在被用于指示允许频道的次要非许可使用。 具体地,如果次要用户结合用于识别次要用户的唯一调制签名的方法,则信标信号的解码可能不是必需的。 考虑到上述情况,当没有在许可频谱内的传输当前正在发生时,无线电将被阻止在频带内传输; 被许可人目前正在频谱上进行传输(例如,利用频谱进行电视传输,或无线电无法感知数据信道(信标)的存在。

    摘要: During operation of a secondary communication system, nodes having different channel monitoring capabilities or requirements will cooperatively monitor possible frequencies for transmissions, each node using only a subset of all possible modulation sensing schemes. All nodes will share channel occupancy information to other nodes within the communication system. For example, a first group of nodes may monitor possible frequencies for television transmissions, while a second group of nodes may monitor the possible frequencies for APCO 25 transmissions. A group of nodes may also cooperatively monitor possible frequencies for more than one type of modulation transmission. Channel information will be shared among the nodes.

    摘要: A method and apparatus for reducing inter-modulation within a wireless communications device (100) is provided herein. During operation a wireless communications device will perform frequency analysis on a received signal (125) to determine if any undesirable IM products exist. If undesirable IM products exist, the incoming signal is attenuated by adjusting an automatic-gain control (AGC) threshold for AGC circuitry (101, 107). By adjusting the AGC threshold, the incoming signal will be attenuated at lower gain values, reducing the amount of IM present within the wireless communications device.
