Techniques are described for wireless communication. One method includes transmitting, from a first communication device, a relay search query to a plurality of relay candidates; receiving a relay search query response indicating a relay that provides at least a threshold device-to-relay-to-device (DRD) capacity for communications between the first communication device and a second communication device; and communicating with the second communication device through the indicated relay based at least in part on the relay search query response.

A system and method for selecting an operator to boost in a repeater are disclosed. Wireless signals are received at a wireless signal booster from two or more mobile phone operators. One selected operator is selected from the two or more mobile phone operators. The wireless signals from the selected operator are then selectively boosted, the selectively boosting repeating the wireless signals from the selected operator in a boosted state for a mobile phone recipient.

A technology is described for a repeater. A repeater can comprise: a server port; a donor port; a first uplink (UL) amplification and filtering path coupled between the server port and the donor port, wherein the UL amplification and filtering path is configured to pass a UL signal of a first band and a UL signal of a second band through a first bandpass filter; a first downlink (DL) amplification and filtering path coupled between the server port and the donor port, wherein the first DL amplification and filtering path is configured to pass a DL signal of the first band and a DL signal of a third band through a second bandpass filter.

Techniques to provide relay server configuration for geographically disparate client devices are described. In one embodiment, an apparatus may comprise a client front-end component operative to receive a relay system request at a relay initiation server, the relay system request for a first client device and a second client device; and transmit a relay system address list in response to the relay system request; and a relay system selection component operative to determine a first service area for the first client device; determine a second service area for the second client device; and retrieve the relay system address list based on the first service area and the second service area, the relay system address list comprising a plurality of selected relay system network addresses for a plurality of selected relay systems of a plurality of relay systems. Other embodiments are described and claimed.

The present invention relates to a method for transmitting and receiving a signal, using a macro base station, through a relay node in a wireless communication system in which a carrier aggregation method is applied. Specifically, the method comprises the steps of: receiving a downlink control channel in a first subframe of a main component carrier; and receiving a data channel on the first subframe and a second subframe after the first subframe, based on control information included in the downlink control channel, wherein the data channel is received through only one or through a plurality of sub-component carriers in the second subframe, and the control information includes a carrier identifier for identifying component carriers and/or a subframe identifier for identifying subframes.

The invention is directed to systems, methods and computer program products for executing a handover operation associated with relay termination. Specifically, the handover operation entails directly connecting a mobile terminal to a base station, which is currently connected to the base station via a relay terminal, and, subsequent to establishing the direct connection, terminating the connection between the mobile terminal and the relay terminal.
