Various embodiments of electronic communication systems and methods in which an infrastructure in-motion adapts from a first set of communication parameters to a second set of communication parameters while moving from one geographical region to a second geographical region, and associated transmission pattern of the infrastructure in-motion may be modified to either avoid a problem of multiple-region-coverage or to resolve such a problem once it has arisen. The infrastructure in-motion may be a base station or other infrastructure, and any or all of multiple techniques such as beam switching, beam selection, phased array, and null-steering, may be used to modify a transmission pattern. In various alternative embodiments, infrastructure in-motion in one geographical region establishes a first backhaul link with a first core network, moves to a second geographical region, and then establishes a second backhaul ink with a second core network.

A technique for offering a reward to an audience member tuned to a broadcast signal which is performed by reproduction equipment, the broadcast signal having commercial content, program content, and commercial content identification codes respectively corresponding to advertisements contained in the commercial content, wherein the audience member captures the commercial content identification codes from the performed broadcast signal and actuates storing of a segment of a program content from the performed broadcast signal. The technique identifies the program based on the segment thereof that was stored in response to the command, and offers the audience member a reward related to the identified program.

Network coding and multiple packet reception (MPR) are used together in a wireless network. In at least one implementation, a novel medium access control (MAC) protocol is provided that enhances throughput in a wireless mesh network that uses network coding and MPR by providing fairness to information flows, rather than fairness to individual nodes.

A relay node for a wireless network is configured for transmissions on the basis of a radio frame with a plurality of subframes. The relay node includes a first relay path and a second relay path. The first relay path is configured to receive, in a first subframe of the subframes, first unicast transmission signals, to decode the first unicast transmission signals to obtain unicast data, and to forward the decoded unicast data by sending second unicast transmission signals in a second subframe of the subframes. The second relay path is configured to receive, in a third subframe of the subframes, multicast transmission signals, to amplify the received multicast transmission signals, and to send the amplified multicast transmission signals in the third subframe. The relay node may switch between the first relay path and the second relay path in order to implement a hybrid Decode-and-Forward and Amplify-and-Forward relaying operation.

In a communication system that includes an access point, a repeater #1, and a repeater #2 and wirelessly communicates with a terminal, the access point wirelessly communicates with the repeater #1 on at least a first channel included in a first frequency band and wirelessly communicates with the repeater #2 on at least a second channel included in a second frequency band different than the first frequency band, the repeater #1 wirelessly communicates with the terminal on at least a third channel included in the second frequency band, and the repeater #2 wirelessly communicates with the terminal on at least a fourth channel included in the first frequency band.
