Abstract: A system for and method of implementing mobile commerce in a satellite radio broadcasting system. A unique program identifier is associated with each program segment of a broadcast. When a listener hears a program segment of interest, the listener causes the associated program identifier to be captured and thereafter to be transferred to a central location or hub. The transferring operation can be accomplished manually, via a media link or via a wireless network. Upon receipt of the program identifier at the central hub, the program identifier is used to determine information about the listener, obtain additional information regarding the program segment associated with the program identifier for the listener and/or initiate an e-commerce transaction involving the listener and/or other parties including merchandisers and advertisers.

Abstract: Methods, systems, and devices are described for managing satellite communications through the deployment of a fleet of multi-beam satellites serving overlapping and non-overlapping spot beams. In these methods, systems, and devices, a first communication service associated with a relatively wider spot beam of a first satellite is provided to a first coverage area having multiple terminals. A second communication service associated with a relatively narrower spot beam (e.g., high-gain spot beam) of a second satellite is provided to a second coverage area located within the first coverage area. A subset of terminals located within the second coverage area is identified, and the terminals of the identified subset are transitioned from the first communication service of the wide spot beam of the first satellite to the second communication service of the high-gain spot beam of the second satellite.

Abstract: Methods, systems, and devices for wireless communication are described. A station (STA) capable of supporting multiple power modes may monitor traffic on a channel. The STA may, based on the monitoring, detect an ongoing voice call between the STA and an access point (AP). Upon detection of the ongoing voice call, the STA may switch power modes from a power mode that does not support power collapse to a power mode that does support power collapse. The STA may also prompt the AP to send a downlink voice packet, if available. After a downlink transmission opportunity corresponding to the prompt occurs, the STA may enter power collapse. The STA may remain in power collapse until a subsequent uplink transmission opportunity occurs.

Abstract: Embodiments include a beam determining unit intended to be connected to a wireless heterogeneous network and a beam-searching method for a wireless heterogeneous network. In the context of a millimeter wave heterogeneous network, it is proposed to do away with the conventional exhaustive beam-searching procedure which is both time and power consuming. Instead, it is proposed a two-step procedure where a line of sight path is determined between a user equipment and a small cell of the millimeter wave heterogeneous network based on positioning information of the user equipment and the small cell. Then, it is determined an optimal antenna beam pair comprising antenna beams at the user equipment and the small cell based on the determined line of sight path and the antenna beam directions available at the user equipment and the small cell level.
