A method for allocating resources in a wireless network includes establishing one or more links. The method also includes the following iterative steps: allocating a first number of slots to the relay links; dividing the first number of slots among the relay links; determining a representative relay data rate indicative of a data rate provided by one of the relay links for one of the multi-hop access links; allocating the second number of slots to the multi-hop access links; dividing the second number of slots among the multi-hop access links; determining the effective multi-hop data rate based on the minimum of the representative relay link data rate and the multi-hop data rate; allocating the third number of slots to the single-hop access links; dividing the third number of slots among the single-hop access links; and upon the single-hop data rate being approximately equal to the effective multi-hop data rate, provisioning the first, second and third number of slots.
摘要:
The embodiments generate a new type of amble sequence for a wireless communication network with mixed nodes, by generating a first amble sequence invisible to a first node based upon an existing amble sequence for the first node and generating a second amble sequence having a low to zero cross-correlation with the first amble sequence, based upon the first amble sequence. The first and second amble sequences can be broadcast in alternating communication link frames.

A method for balancing network load includes determining an initial capacity of a wireless network comprising a plurality of endpoints coupled to a plurality of different types of access stations. The access stations comprise one or more relay stations and at least one base station. The method also includes identifying one or more endpoints that would increase capacity of the wireless network if switched to a different access station. The method further comprises tentatively switching the identified endpoints from their current access station to a different access station. The method additionally includes determining if the capacity of the wireless network is increased from the initial capacity by the tentative switch and, upon the capacity of the wireless network increasing, switching the identified endpoints from their current access station to a different access station.

According to an embodiment, a method is provided. The method includes identifying a femto base station of a wireless network as the home femto base station for a mobile station served by the wireless network. The connection parameters for the home femto base station may be stored at the mobile station. A home macro base station may be identified and associated with the home femto base station. Identification information for the home macro base station may be stored at the mobile station. Association information of the home femto base station with the home macro base station may be stored at the mobile station.
摘要:
The embodiments provide transmitting at same time first and relay second node preambles aligning data frames among the first node and the relay second node wirelessly communicating in a channel and transmitting by the first node one or more radio resource control parameters managing radio resources of the wireless communicating in the channel among the aligned first node and the relay second node. A relay resynchronization amble sequence managing synchronizing in the channel the first node frames with the relay second node frames is periodically transmitted to the relay second node.

A method for reusing wireless resources in a wireless network, includes determining the probability of a first communication with a first relay station experiencing interference from a second relay station. The method also includes, upon determining that the probability of experiencing interference from the second relay station is greater than an interference threshold: allocating a first wireless resource to the first relay station and the second relay station; designating the first wireless resource as a primary wireless resource for the first relay station; designating the first wireless resource as a secondary wireless resource for the second relay station; allocating a second wireless resource to the second relay station; and designating the second wireless resource as a primary wireless resource for the second relay station.
