    摘要: An enhanced beamforming with interference nulling method is an improvement over prior art beamforming with interference nulling techniques. The enhanced method includes two scheduling schemes that allow all base stations to schedule their cell edge users independently and determine the information exchange among base stations over the backbone that is needed to support the scheduling activity. The method uses grouping information to perform distributed scheduling among base stations to schedule downlink transmission to cell edge users, while reducing interference to cell edge users served by neighboring base stations. The enhanced method demonstrates the base station-to-base station coordination and information exchange that is needed to enable independent base station scheduling of their cell edge users.

    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: A technology for a user equipment (UE) is disclosed that is operable in an anchor-booster architecture of a multiple radio access technology (multi-RAT) heterogeneous network (HetNet). Control information to an anchor cell can be transmitted from a wireless wide area network (WWAN) node in the multi-RAT UE. Data packets of the multi-RAT UE can be selected for transmission via one of the WWAN node and a wireless local area network (WLAN) node in the multi-RAT UE using a multi-RAT coordination function (MRCF) module. Each data packet from one of the WWAN node and the WLAN cell can be transmitted to a multi-RAT small cell evolved node B (SC-eNode B) based on the selection by the MRCF module.

    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.
