Abstract: When a wireless device is configured to function as a relay for a donor access node, the donor access node is configured such that the relaying wireless device is given preferential treatment when compared to non-relaying wireless devices. The communication network and/or donor access node can be configured to provide improved RF conditions, higher throughput, lower latency, etc. to a relaying wireless device than is provided to non-relay wireless devices.

Abstract: A wireless mesh network is configured. Each node is configured to function as either a gateway node or a relay node. To configure itself as a gateway node, an access node selects an SSID for each of its wireless interfaces that indicates it is an access node. When a relay access node is configuring itself, it scans for the SSIDs of available networks. The SSIDs of the mesh network are selected to indicate the number of other access points between a given access node and a direct wired connection (which is zero in the case of a gateway node.) The relay access node connects to the network having an SSID that indicates the fewest number of hops between itself and a direct wired connection. The SSID that is broadcast by the relay access node indicates the number of other access points between itself and a direct wired connection.

Abstract: Systems and methods are described for providing multiple voice service modes to a wireless device using data packet transmission through a wireless network. Application requirements including a signal level threshold for a wireless device may be determined. Signal level information for the wireless device may be received and transmitted among various network nodes. The received signal level may be compared with the signal level threshold for the wireless device. The wireless device and the access node may communicate wirelessly to provide voice services to the wireless device application. Data transmission may be converted between a first mode and a second mode depending upon a relative position of the received signal level with respect to the signal level threshold. The second mode of data transmission may be used where the first mode of data transmission cannot because the second mode may consume less network resources.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. A first access node can determine a scheduling scheme based on data addressed to wireless devices in communication with the first, second, and third access nodes. The data addressed to the wireless devices in communication with the first access node can be transmitted during a first subframe of the scheduling scheme where the first access node does not transmit data addressed to the wireless devices in communication with the first access node during a second subframe of the scheduling scheme. The second and third access nodes can be instructed to assign data addressed to wireless devices that do not meet a signal condition threshold to be transmitted during the first subframe and to assign data addressed to wireless devices that meet the signal condition threshold to be transmitted during the second subframe.

Abstract: Reference signals (a.k.a., pilot signals) are broadcast to aid in at least channel estimation, cell selection, and handover. When a multi-antenna mode (i.e., MIMO) is used data signals on one antenna should not interfere with reference signals on another antenna. Reference signal resource elements (a.k.a., slots) being broadcast from one antenna are multiplied by a first Walsh code and the data (or reference) signal resource elements being broadcast from another antenna are multiplied by second Walsh code in the same family. Multiplication by Walsh codes reduces or eliminates the correlation between the data resource elements on a first antenna and the reference signal resource elements simultaneously broadcast on a second antenna.
