摘要： An approach is provided for mitigating interference from Long Term Evolution (3GPP LTE) terminals to adjacent frequency bands. A platform determines whether a region associated with transmission of one or more resource blocks are an interfering region according to predetermined criteria, where one or more resource blocks are assigned a primary carrier as a default carrier for the transmission. The platform selects a secondary carrier for the one or more resource blocks instead of the primary carrier if the region is determined to be interfering.

摘要： A transmission method for multi-antenna retransmission is provided, comprising steps of: generating the bits to be transmitted by respective antennas; mapping the bits to be transmitted by the respective antennas into symbols; and multiplying by a constant the vector constituted by the mapped symbols transmitted by multiple antennas, wherein the resulting vector is orthogonal to the matrix constituted by the symbols previously transmitted by multiple antennas, and transmitting the orthogonal symbols. According to the method of the present invention, the remapped symbols transmitted by the respective antennas and the symbols previously transmitted by the respective antennas constitute a matrix that has an orthogonal property. The orthogonal property can be used to effectively detect signals. In addition, the method has a reception algorithm with low complexity and brings about significant performance gains over conventional methods.

摘要： Network Allocation Vector (NAV) and “beam access control” (BAC) techniques are provided to address data collision problems in WLANs wherein APs provide wireless network access in a service area defined by multiple sectors via use of a switchable antenna system or the like. Preferably, every time the AP visits a sector and before the AP moves on to the next sector, the AP can set the NAV equal to the time it will take until its next visit. Alternatively, or in addition, a BAC bit is transmitted by an AP to control access to the AP by WTRUs disposed in a service sector in which the BAC is transmitted.

摘要： First normalizing means (12) normalizes first and second code streams (s1, s2). First spreading means (13) spreads the output of the first normalizing means (12). STTD coding means (14) subjects the first and second code streams (s1, S2) to STTD coding. Second normalizing means (15) normalizes the output of the STTD coding means (14). Second spreading means (16) spreads the output of the second normalizing means (15) by means of the same spreading code as that of the first normalizing means (12). Orthogonal transforming means (17) gives the negative signs to odd chips in a second path spread sequence of each code and exchanges the orders of the odd and even chips. Combining means (18) adds first and second spread sequences of the second path produced by orthogonally transforming the first and second spread sequences of the first path. With this, by using the orthogonality of the transmitted sequences at the receiving side, the reception signal can be detected with a lower complexity.

摘要： A smart antenna steering algorithm performs a self-monitored re-scan during a sustained use period after having selected a preferred antenna beam. During a sustained use period, a re-scan of the other antenna beams is not performed. The steering algorithm periodically monitors a quality metric of the ongoing radio link provided by the preferred antenna beam. The quality metric is based upon a signal quality metric and a link quality metric. If the quality metric drops below certain thresholds during the sustained use period, the steering algorithm either swaps the preferred antenna beam with an alternate antenna beam or initiates a re-scan of the available antenna beams for selecting a new preferred antenna beam.

摘要： A smart antenna steering algorithm operates in response to different functions monitored by the media access control (MAC) layer within a client station. One function is when the MAC layer indicates that the client station has been placed in a power savings mode. In response, the antenna algorithm stores an index of the currently selected antenna. Another function is when the MAC layer indicates that the client station has not been synchronized, associated and authenticated with an access point. In response, the algorithm selects an omni-directional antenna beam as the default antenna beam. Another function is when the MAC layer provides beacon period synchronization information to the antenna steering algorithm so that the algorithm can update its own timer.
