摘要： In a wireless wide area network (WWAN) scenario, communication between UEs is facilitated through uplink/downlink channels between the UEs and a base station (i.e., WWAN link or WWAN communication). In the case that two communicating UEs are in the vicinity of each other, direct peer-to-peer communication without passing through the base station may reduce a base station load. In some scenarios, it is beneficial for devices, with no or limited WWAN capability to also participate in peer-to-peer communication. Accordingly, a method, an apparatus, and a computer program product for wireless communication are provided in which control information from a user equipment (UE) is received, the control information including information indicating resources for peer-to-peer communication, a peer-to-peer link with the UE to receive authentication information for using the resources is established, and the resources are used to communicate with a peer device.

摘要： A method, a computer program product, and an apparatus are provided. The apparatus determines an availability of a wireless wide area network (WWAN) subframe, and utilizes the WWAN subframe for peer-to-peer communication when the WWAN subframe is available. Accordingly, peer mobile terminals or devices may establish direct peer-to-peer links for communicating small amounts of information without affecting the quality of existing WWAN communications. In the wireless wide area network (WWAN) scenario, communication between mobile terminals is facilitated through uplink/downlink channels between the mobile terminals and a base station (i.e., WWAN link). Therefore, for various types of applications, an efficient means of communicating a small amount of information frequently is provided that does not require large amounts of signaling overhead.

摘要： A method of operating a first wireless device includes receiving a grant from a base station for peer-to-peer communication with a second wireless device using time-frequency resources utilized by a third wireless device for WWAN communication with the base station. In addition, the method includes receiving a transmit power for the peer-to-peer communication with the grant. The transmit power is determined based on an interference that can be caused to transmissions received by the base station from the third wireless device. Furthermore, the method includes communicating with the second wireless device at a power less than or equal to the received transmit power using peer-to-peer communication on the time-frequency resources.

摘要： Method and apparatus for an access terminal which makes handoff decisions between a number of potential alternative attachment points based on service level indicating metrics are described. The access terminal computes a service level indicating metric differently for a current connection than for a potential alternative connection. A service level indicating metric is a function of loading information and received signal strength. A selection may be made by selecting between attachment points by selecting the attachment point having the highest service level indicating metric from among a plurality of attachment points, one per possible carrier where the attachment point which is considered for a given carrier is the one having the best connection for the given carrier. The access terminal handoff decision approach provides handoff decisions which are nearly as optimal as those which can be achieved using a centralized control node but without the requirement for centralized handoff decisions.
