摘要： A femtocell increases efficiency and coverage of a macrocellular network operating in a co-channel manner within the macrocell spectrum by selecting subcarriers for its mobile station using both the subcarrier allocation map received from the macrocell and a spectrum sensing operation. Interference is avoided by selecting only subcarriers not allocated by the macrocell and subcarriers allocated to users not nearby to the femtocell. Interference is eliminated from the received signals using co-channel interference avoidance techniques. Selection of subcarriers for femtocell use may take into consideration inter-carrier interference detected.

摘要： A method and a communication system including femtocells within a macrocell efficiently manage interference between the different femtocells, and between each femtocell and a macrocell. An efficient frequency assignment scheme for the femtocells minimizes interference between a femtocell and a macrocell and among different femtocells using a spectrum-sensing technique carried out by the femtocells. The frequency assignment scheme selects a suitable channel from a set of candidate channels and ensures that the femtocell has an acceptable coverage area even when it is close to the macrocell base station (BS). The frequency assignment scheme favors a co-channel implementation to take advantage of the hand-off and cell search characteristics of the co-channel implementation. In one embodiment, a joint power control and frequency band assignment technique is used, which partitions the coverage area of the macrocell into an inner region, a power control region, and an outer region.

摘要： An apparatus and a method proactively manage the load of an 802.11 WLAN based on one or more per-class station counts, in which the stations are classified according to access categories (ACs), user priorities (UPs), or services. Alternatively, the load of an 802.11 WLAN may also be proactively managed based on provisional or non-provisional per-class traffic specification (TSPECs), depending upon the status of traffic streams (TSs). Load balancing may be achieved by (a) collecting per-class station count information, either through an AP, or through exchanges with neighboring APs or wireless stations, and (b) proactively influencing association decisions between wireless stations and APs. A wireless station may be classified according to ACs, UPs, or services. Alternatively, load balancing may be achieved by (a) collecting provisional or non-provision per-class traffic specification (TSPEC) through an AP, or through exchanges with neighboring APs or wireless stations, and (b) proactively influencing association decisions between wireless stations and APs.

摘要： Disclosed herein are systems and methods for communicating a number of data flows on a single communications channel. In one embodiment, a method of communicating a number of data flows on a shared communications channel includes the acts of (1) calculating a set of optimum goodput rates for the data flows, in order to maximize a total utility of the data flows, (2) calculating a set of optimum throughput rates for the data flows based on the optimum goodput rates, and (3) transmitting the data flows on the shared communications channel with the optimized throughput rates. Optimization is preferably done using utility functions that indicate the utility of the data flows as a function of their goodput rates. The method can additionally block temporarily a transport layer of at least one of the data flows if the transport layer of that data flow is bottlenecked.

摘要： In a fast active scanning wireless network apparatus and method for quick determination of available access points, information about a candidate set of available access points is obtained, and a candidate access point is identified from the candidate set. A mobile station then queries the candidate access point with a probe request that designates the candidate access point as a sole responder. The probe request prevents other access points from contending for the medium of communication between the mobile station and the designated sole responder access point by excluding the attempt by other access points to transmit probe responses. The apparatus and method thus increases the probability of a fast and successful probe request from the mobile station and subsequent response from the designated access point. The designated access point may also respond with a probe response of high priority, preventing intervention of communication.

摘要： In one embodiment, the unit share data rates for a plurality of mobile stations are determined with regard to two resource groups. A differentiation factor for each mobile station is formed from a ratio of its unit share data rates. The resulting differentiation factors are sorted and classified into two groups according to a proportional fair border determining function. A first one of the resource groups is allocated to the mobile stations corresponding to a first one of the differentiation factor groups. Similarly, a second one of the resource groups is allocated to the mobile stations corresponding to a remaining second one of the differentiation factor groups.
