摘要： In a system including one or more femtocells within a service area of a macrocell, a method includes: (a) receiving from a base station of each femtocell information regarding available resources at the femtocell; (b) measuring an signal-interference-to-noise ratio (SINR) at a mobile station relative to the macrocell and each femtocell; and (c) selecting for the mobile station one of the femtocells for a hand-off, wherein the femtostation is selected based on the combined capacity of the macrocell and the femtocells after the hand-off. When a hand-off to a femtocell is not allowed, a method for determining whether or not a spectral resource of the macrocell is reused includes (a) receiving from a base station of the macrocell a first set of spectrum-sensing data, the first set of spectrum-sensing data comprising spectrum-sensing data of mobile station of the macrocell; (b) receiving from one or more mobile stations associated with the femtocells a second said of spectrum-sensing data; and (c) based on the first set of the spectrum-sensing data and the second set of spectrum-sensing data, determining whether or not to reuse in a femtocell a portion of a spectrum used by the macrocell. The determining step may be carried out at a base station of a femtocell, and the method further requires sensing a spectrum at the base station of the femtocell to obtain a third set of spectrum-sensing data, which is also used in determining whether or not to reuse the portion of the spectrum used by the macrocell.

摘要： A mobile communication system uses a multiple-input-multiple-output (MIMO) technology with an orthogonal frequency division multiplexing access (OFDMA) scheme. At network entry, an initial ranging method selects from multiple ranging signal designs to accomplish the initial ranging process. Three classes of ranging signal designs may be selected for use in generating ranging codes. The information on the ranging signal design to be used, which is selected by the base station based on the cell size of the communication system (i.e., the radio coverage area of the base station), is broadcast from the BS. The ranging signal designs are directly applicable to single-antenna systems, and they are applied to MIMO systems by using appropriate mapping across transmit antennas based on the adopted MIMO ranging transmission scheme. Optimum eigenmode and suboptimum eigenmode transmission schemes provide the best performance at high computational complexity and high power consumption.

摘要： A cooperative communication scheme is provided for a base station (BS) to communicate with a mobile station (MS) through a group of relay stations (RSs). The RSs, collectively referred to as a relay-associated group of RSs (R-group), serve the same target MS. The R-group may be formed during initial ranging or during periodical ranging of the MSs, according to the channel conditions between the MSs and the RSs. A reliable relay-associated transmission scheme provides fast recovery and reduces the burden on the BS. In one exemplary scheme, the BS transmits data to the R-group. To ensure that reliable transmission exists between the BS and the R-group, the BS initially sends the information to all the RSs in the R-group using multicast or unicast mode. In one embodiment, after receiving the packets from the BS, each RS in the R-group calculates its reliability value according to a reliability function which may depend on (a) the channel conditions between the BS and the RSs, (b) the channel conditions between the RSs and the MS, and (c) the load status at the RSs. The RSs then feedback their reliability values in a message (“relay-associated acknowledgement message” or R-ACK).
摘要翻译：提供了一种协作通信方案，用于基站（BS）通过一组中继站（RS）与移动台（MS）进行通信。统称为RS（R-group）的中继相关组的RS服务于相同的目标MS。根据MS和RS之间的信道条件，可以在初始测距期间或在MS的周期性测距期间形成R组。可靠的中继相关传输方案提供快速恢复并减轻BS的负担。在一个示例性方案中，BS向R组发送数据。为了确保BS与R组之间存在可靠的传输，BS首先使用多播或单播方式将信息发送到R组中的所有RS。在一个实施例中，在从BS接收到分组之后，R组中的每个RS根据可靠性函数计算其可靠性值，该可靠性函数可以取决于（a）BS与RS之间的信道状况，（b）信道 RS和MS之间的条件，（c）RS处的负载状态。然后，RS在消息（“中继相关确认消息”或R-ACK）中反馈其可靠性值。

摘要： In a wireless communication system including a base station and multiple mobile stations, a method transmits an orthogonal frequency division multiple access (OFDMA) data frame to the mobile stations. The method includes the steps of (a) at the beginning of the data frame, collecting metrics representing channel conditions for each of the channels; (b) assigning each mobile station to one or more communication channels based on the metrics collected; (c) for each symbol in the frame, calculating an average bit-error-rate for each of a number of transmission modes, and assigning to that symbol the transmission mode corresponding to the lowest calculated average bit-error-rate for that symbol; and (d) transmitting the symbols in the frame according to their respective assigned transmission mode. In addition, a bit-loading optimization step may be carried out in conjunction with the method to determine a modulation order for each symbol to be transmitted.

摘要： Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.

摘要： Methods for increasing power saving in a station that sends or receives frames in an ad hoc wireless network (e.g., IBSS), while allowing the station to enter a power-saving mode quickly upon completion of scheduled tasks. At the same time, a method of the present invention allows two stations in the ad hoc wireless network to infer each other's power management mode without requiring an ATIM/ACK exchange between the STAs within an ATIM window. Consequently, a station may enter a power-saving mode promptly without impairing the station's ability to receive packets. In one embodiment, a “more data” field is used between stations to exchange information. Stations with various computation abilities provide information under different time constraints. The stations may enter power-saving modes that send multicast/broadcast frames or use promiscuous mode within an ATIM window.

摘要： Channel scanning for wireless networks, such as Wireless Local Area Networks (WLANs), generally provides a wireless station with the information on the available WLAN resources, such as the frequency band and the maximum transmission power. The present invention provides safe and fast domain-aware channel scanning, enabling a wireless station to comply with applicable local regulations, in spite of the possibility of domain changes, with short channel-scanning time. Fast channel scanning is accomplished by active channel scanning if valid domain information is available and there is no possibility of domain change. Also, domain-independent channels, if any, are first scanned using active scan to get domain information faster.
