摘要:
In a wireless network, a lowest cost path from a source node to a target node is selected from a plurality of potential paths. The source node sums costs for the links of each potential path. For each link, these costs include a cost of interference, dependent on a number of nodes affected by a signal sent via the respective link. The link costs can also include a cost of transmission, dependent upon a data rate for the respective link, and a cost of coordination for transmissions with other nodes of the network.

A system and method are provided for mitigating interference between wireless access points (APs). A user equipment (UE) device uses a first set of radio resources to wirelessly communicate with a first AP and a second set of radio resources to wirelessly communicate with a second AP. The UE device then uses the first and second radio resources to communicate cooperation data between the first and second access points to mitigate interference thereinbetween.
摘要:
In a packet-based wireless access network, packet route selection is made in a terminal which communicates with the network via a wireless link. The route selection process uses information provided by the network relating to links in the network, and information available in the terminal relating to its wireless link to the network. Consequently the selected route may be via a wireless link between the terminal and a network node that does not provide the best signal strength but has the best prospect of providing a required Quality-of-Service (QoS) for a traffic flow. Monitoring enables the terminal to update the route selection to maintain the required QoS, despite changing conditions and handover, without a need for signalling messages.

A system and method are disclosed for exchanging data in a heterogeneous wireless communications environment. A mobile device initiates a first communication session with a first radio access network (RAN) that is connected to a wired network comprising a remote fixed node (RFN). A first set of data exchange transactions with the RFN is initiated by the mobile device during the first communication session to exchange a first set of data. The mobile device then initiates a second communication session with a second RAN that is likewise connected to the wired network. A second set of data exchange transactions with the RFN is initiated by the mobile device during the second communication session to exchange a second set of data contemporaneously with the first set of data exchange transactions.

摘要:
The present application describes a system and method for dynamically employing split-physical layer (PHY) functionality across multiple access heads to establish multiple paths between a client device (CD) and an access network in order to address one or more of the above described coverage issues. In some embodiments multiple input multiple output (MIMO) space-time coding is employed. Space-time coding may include contemporaneously transmitting one spatial stream or multiple spatial streams through each access head. In some embodiments macro diversity is also employed. Macro transmit diversity may include transmitting a same signal, consisting of one or more spatial streams, from one or more access heads such that a CD can use a strongest signal of the signals transmitted from at least one access head or diversity combining of two or more of the transmitted signals to recover the transmitted signal at the CD. Space-time coding may include contemporaneously receiving one spatial stream or multiple spatial streams through each access head. Macro receive diversity may include receiving a same signal from a CD at one or more access heads such that a strongest signal of the signals received at one or more access heads can be used to recover a signal or diversity combining of two or more of signals received at different respective access heads can be used to recover the transmitted signal.
