Techniques are described of forming a mesh network for wireless communication. One method includes broadcasting, from a first node connected to a core network, a beacon signal, receiving a connection establishment request from a second node in response to the broadcasted beacon signal; determining a radio resource availability associated with a plurality of radios of the first node based on the connection establishment request, and establishing a connection with the second node using a radio of the plurality of radios based on the radio resource availability. In some cases, the radio resource availability may include a number of active connections associated with one or more radios of the plurality of radios of the first node.

Autonomous mesh topology

A method for signalling in a MIMO system. The system comprises a base station (BS), and at least one relay station (RS), operating in half duplex realized using Time Division Duplex. The BS and the RS distribute channels to at least one mobile station (MS), The method is particularly characterized in the steps where:-the BS selects at least one RS which is served during a first time slot (TS1), and selects at least one MS which is served during a second time slot (TS2),&#x2014;the BS creates channels during T1 to said RS,&#x2014;the BS and said RS create channels during T2 to said MS.

Relays in multi-user MIMO systems

The invention relates to a method for carrier recovery of an equalized communications signal in a multiple-input multiple-output communications system. The method is comprised of the steps generating a phase rotation estimate from the equalized communications signal and a demodulated signal estimate of the equalized communications signal, and adjusting at least one of the phase and frequency of the equalized communications signal based on the phase rotation estimate. The step of generating the phase rotation estimate further comprising using a model based filter with the equalized communications signal as input signal to the model based filter and the demodulated signal estimate as a measurement to the model based filter.
