Abstract: Supplemental node transmission assistance in a wireless network provides for transmissions between a wireless network and wireless user equipment in a first direction using a serving node of the wireless network while providing for transmissions between the wireless network and wireless user equipment in a second direction using a supplemental node of the wireless network. The supplemental node is selected based on providing better channel conditions between the network and the user equipment in the second direction than the serving node. The supplemental node thus provides transmission assistance for the serving node in order to provide the best available downlink and uplink communications between the user equipment and the network.

Abstract: A method and system for formulating an SINR metric for cells using only the existing RSRP and RSRQ measurements. With this method and system side information is exchanged between eNBs of an E-UTRAN using the X2 interface where the X2 interface carries the X2 Application Protocol (X2AP). The side information is introduced either within X2AP messages exchanged between eNB nodes or via modification of existing X2AP messages. Serving cell system information block (SIB) messages may also be modified or new SIB messages introduced to facilitate computation of an SNIR metric at a UE.

Abstract: To perform wireless communications in a wireless network, at least two spatial beams are formed within a cell segment, where the at least two spatial beams are associated with different power levels. The at least two spatial beams are swept across the cell segment according to a sweep pattern. In some implementations, multiple antenna assemblies can be used, where each antenna assembly has plural antenna elements. A lower one of the antenna assemblies can be used to form high and lower power beams, and an upper one of the antenna assemblies can be used to communicate backhaul information, for example.

Abstract: The invention includes systems and methods for improving the performance of non-blocking data switching systems. One embodiment of the invention includes a method comprising routing data from a plurality of inputs to a plurality of outputs through a switching core according to a first switching schedule, receiving a first set of reports comprising reports from data sources associated with the plurality of inputs, evaluating one or more reports of the first set of reports, determining a sufficiency of the first switching schedule based on the one or more reports, adapting a second switching schedule, wherein the second switching schedule differs from the first switching schedule, sending the second switching schedule to the data sources, issuing one or more synchronization signals associated with a transition to the second switching schedule to the data sources and routing data from the plurality of inputs to the plurality of outputs through the switching core according to the second switching schedule.

Abstract: Methods and systems for dynamically computing a schedule defining interconnections between ports in a switching system. In one embodiment, a switching core requests demand reports from the ingress ports. In response to this request, the ingress ports generate a series of suggested port schedules, beginning with a first choice, then a second choice, and so on. The schedules are transmitted to the switching core, beginning with the first choice. The switching core receives the first choice for each of the ports and determines whether the aggregate schedule defined by the first choices is valid. If the aggregate schedule is valid, then this schedule is implemented. If the aggregate schedule is not valid, portions of it are discarded and the next choice from each of the ports is examined to identify connections to replace the discarded portions. This process is repeated until a valid schedule is obtained.

Abstract: A non-blocking optical matrix core switching method that includes maintaining a schedule for routing data through an optical matrix core and receiving and analyzing reports from peripheral devices. The method determines whether the schedule is adequate for the current data traffic patterns and if the schedule is not adequate a new schedule is implemented. The new schedule is then transferred to the peripheral devices for implementation and the new schedule is transferred to the optical matrix core scheduler. Implementation of the new schedule as the schedule on the peripheral devices and the optical matrix core scheduler is then performed.
