    摘要: A method for managing and allocating radio resources (RRMA method) of multiple radio resource types to subscriber stations is disclosed. The RRMA method includes bandwidth partitioning, into parts comprising “slots” with a given reuse pattern, a selection rule, to select a “cell, reuse pattern” pair serving each user, and an allocation rule, for distributing to each user an appropriate number of bandwidth slots from the selected “cell, reuse pattern” pair. After an adaptation period, the method reaches a desired fairness, while simultaneously reaching a maximal mean throughput, possible under this fairness. For big networks, the method provides basically decentralized radio resource management. The RRMA method is useful to cellular networks having a single set of orthogonal sub-channels (frequency/time slots) being reused by all network cells, such as time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), or OFDMA/TDMA cellular systems. Particularly, the method is applicable in fractional frequency reuse cellular networks.

    摘要: Techniques are described that can be used to maximize the interference suppression capability of space-time coded systems by managing synchronous transmission signaling. To enhance the probability of the occurrence synchronous interference and accordingly increase interference cancellation capability at a receiver, a network of at least two transmitters in a network may utilize similar structured coding schemes and coordinate transmission so that the receiver receives co-channel signals synchronously.

    摘要: In various embodiments, two wireless communication devices may communicate with each other using multiple protocols, by dividing the data to be communicated into multiple portions, and using each protocol to communicate different portions. The different protocols may be used simultaneously or concurrently. This multi-protocol technique may be used in several different ways to provide different types of advantages in wireless communications.

    摘要: An interference mitigation system randomizes transmissions to cell-edge users by carefully controlling the probability of transmission to these users, thereby creating a virtual fractional frequency system that does not require extensive frequency management and coordination across the network. In some embodiments, the interference mitigation system identifies severely interfered links and reduces the probability of transmission on these links, with the result being a reduced probability of interference.

    摘要: A method and apparatus to manage interference in a multi-cellular network is disclosed. This approach uses downlink power control to allow a serving femto access point of a plurality of femto access points to transmit signals at a first power level to ensure a quality of service level of a service provided to a first plurality of mobile stations served by the plurality of femto access points. This approach also uses the downlink power control to adjust a power level of the signals transmitted by a serving femto access point of the plurality of the femto access points to manage interference caused by the serving femto access point on a second plurality of mobile stations served by one or more macro base stations.
