摘要:
FCH locations are mapped to preamble sequence sets to allow more than three stations to transmit their FCHs with minimized or reduced interference. A lower interference environment may be provided to transmit the FCH within each DL relay phase when the number of stations within the phase is less than the number (L) of distinct FCH locations. With more than L stations in a DL relay phase, a reduced interference environment for FCH transmission may be achieved by assigning the same FCH location to RSs that are far away from each other.
摘要:
A station grouping mechanism has been presented for a wireless device that collects Multi-hop Relay Base Station (MR-BS) and Relay Stations (RSs) into groups according to their locations in a tree topology and assigns them with a phase. Grouping or partitioning MR-BS and RSs and assigning a distinct phase to the group prevent the MR-BS and the RSs from transmitting and receiving at the same time.

摘要:
An interleaved frame structure provides the ability for access links and relay links to share a single channel and enable the transmission of packet information across a 2-hop path within one frame. The interleaved frame structure in combination with fast processing at the Relay Station (RS) allows scheduled packet information to travel from a Mobile Subscriber (MS) to its MR enabled base station (MR-BS) within one frame.
摘要:
A wireless device to configure a frame structure with multiple phases to support any hop network and any number of Relay Stations (RSs) deployed without increasing overhead proportionally with the number of RSs deployed in the system.
摘要:
A protocol framework for MS handover in MR networks includes new messages and an optimized flow of these messages. A framework for use in a multi-hop topology of MR networks optimizes the handover performance. The framework is applicable and expandable to the design of a new control message exchange procedure for MS handover.
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.
