摘要： A wireless communications system supports both cellular communications and direct peer to peer communications. The cellular communications use FDD downlink and uplink bands for control and traffic signaling. An access point employs control over direct peer to peer communications. Peer to peer mode control signals from the access point are transmitted to wireless terminals using the FDD cellular downlink band. Peer to peer mode control signals from wireless terminals are transmitted to an access point using the FDD cellular uplink band. Peer to peer traffic signals between wireless terminals are communicated using a TDD band. In one embodiment, the access point communicates priority information to peer to peer network wireless terminals, and the wireless terminals make peer to peer traffic transmission decisions in a decentralized manner using the received priority information. In another embodiment, the access point directly schedules peer to peer traffic in the peer to peer network.

摘要： A method of wireless communication includes determining peer-to-peer scheduling resources. The peer-to-peer scheduling resources are parallel in time to and multiplexed with non peer-to-peer resources. The peer-to-peer scheduling resources include a plurality of serial scheduling resource segments. Each of the serial scheduling resource segments provides contention resolution for a set of peer-to-peer links. In addition, the method includes communicating in one of the serial scheduling resource segments and/or the non peer-to-peer resources.

摘要： Techniques for transmitting information in a long term evolution (LTE) wireless communication network are disclosed. A base station may receive a first user equipment (UE) expression and first UE location information of a UE seeking peers. The base station may also receive a second UE expression and second UE location information of at least one of the peers. In accordance with the first and second UE expressions and the first and second UE location information, the base station may match ones of the peers proximate to the UE. The base station may transmit, using a data exchange efficiency technique, information to alert the UE to the presence of the peers. This transmission may comprise wide area network (WAN)-specific signaling.

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.

摘要翻译： 在无线广域网（WWAN）场景中，通过UE和基站（即WWAN链路或WWAN通信）之间的上行链路/下行链路信道来促进UE之间的通信。 在两个通信的UE处于彼此附近的情况下，不经过基站的直接对等通信可以减少基站负载。 在某些情况下，对于没有或有限的WWAN功能也可以参与点对点通信的设备是有益的。 因此，提供了一种用于无线通信的方法，装置和计算机程序产品，其中接收到来自用户设备（UE）的控制信息，所述控制信息包括指示用于对等通信的资源的信息， 建立与UE的对等链路以接收用于使用资源的认证信息，并且使用该资源与对等设备进行通信。

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.
