摘要： In wireless system, a group of Base station (BTSs) with smaller footprints have the capability to communicate with each other as well as with the BTSs with relatively larger footprints via wireless air-interfaces. One of such example is coordinated cell systems. A coordinated cell system comprises a group of coordinated cell base stations that have the capability to communicate with each other as well as with relevant macro cell or Pico cell base stations via wireless air-interfaces. Each coordinated cell BTS consists of an over the air control unit in addition to the conventional coordinated cell BTS system. A set of protocols in the form of messages and database are also defined to enable the networking capability. This enables enhancement in performing a variety of tasks by coordinated cell systems, including interference management and coordination, registration and authentication, quality of service coordination, installation and maintenance, location services, etc.

摘要： In wireless system, a group of Basestations (BTSs) can be managed by a centralized network management identity or can be self-organized by communicating with each other via wireless air-interfaces or wired interfaces. One such example are Femtocell systems. When the BTSs are using the same frequency for transmitting and receiving with relatively large transmitting power and when they are closer to each other, performance of such a system and user throughput or QoS (Quality of Service) gets degraded due to the interference between the BTSs and among the users. Smart antenna technique can be used in a coordinated way among a group of BTSs, such as Femtocells, to avoid or reduce interference or manage how interference happens to achieve performance enhancement such as higher system throughput or better QoS to individual applications.

摘要： Method for packet transmission scheduling in a multi-carrier communications system. A preferred embodiment comprises selecting a set of users from a group of users who are targets of intended transmissions, wherein the selection is based upon channel quality information, determining a set of transmission parameters for each user in the set of users, and scheduling transmissions to the set of users. The channel quality information, which can be provided by the users of the multi-carrier communications system, can permit the exploitation of frequency diversity inherent in the multi-carrier communications system to increase system capacity to beyond a simple sum of carrier transmission bandwidth.

摘要： Method for exploiting frequency diversity in a multi-carrier communications system to improve retransmission performance. A preferred embodiment comprises receiving the request for retransmission, formatting data for the retransmission, selecting a carrier from a plurality of carriers, and transmitting the retransmission on the selected carrier. The selected carrier may be different from a carrier used transmit the damaged transmission, thereby frequency diversity is exploited to change the probability of successful transmission in the retransmission. Alternatively, the retransmission may take place at a later time, to permit changes in the selected carrier to take place and obtain frequency diversity via the changed carrier.
