摘要： Systems and methodologies are described that facilitate supporting mobility for UEs and relay eNBs in split-cell relay configurations. Parameters regarding communicating with one or more UEs can be provided to disparate eNBs from a donor eNB to provide mobility for one or more of the UEs or a serving relay eNB. In addition, a donor eNB can request establishment of one or more radio bearers at a target relay eNB for continuing communications with one or more UEs. Moreover, a donor eNB can provide information regarding one or more core network bearers to a target donor eNB to facilitate establishing the core network bearers at the target donor eNB for communicating with the one or more UEs. Furthermore, uplink buffer contents from a relay eNB can be provided to a target donor eNB so communications from the one or more UEs can be continued by the target donor eNB.

摘要： Methods and apparatuses are provided that facilitate routing of messages of a positioning protocol, such as long term evolution (LTE) positioning protocol annex (LPPa). A positioning server can determine a network area identifier of one or more messages based at least in part on an identifier of a base station associated with the one or more messages. Based at least in part on the network area identifier, the positioning server can provide the one or more messages to an intermediate network node corresponding to the one or more base stations, such as a mobility management entity (MME). MME can similarly provide the one or more messages to an optional gateway between it and the one or more base stations based at least in part on receiving the network area identifier in the one or more messages. In addition, a base station can update positioning information with the positioning server.

摘要： Local IP access paging schemes facilitate paging of an access terminal when packets destined for the access terminal are received via local IP access. In some implementations, a local entity acquires information that enables local paging of the access terminal by sniffing messages passing through the local entity. In some implementations, a local entity sends a packet or message to cause the core network to page an access terminal when a local IP access packet destined for the access terminal arrives at the local entity.

摘要： Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

摘要： Systems and methodologies are described that facilitate packet routing among relay nodes in a wireless network. Bearer quality of service (QoS) mapping is provided for internet protocol (IP) relays by utilizing differentiated services (DiffServ) code point (DSCP) values to determine a bearer for communicating related packets. In addition, SDF filtering at a gateway node can be modified to route packets over certain tunnels to provide QoS for the packets.

摘要： Systems and methodologies are described that facilitate compressing headers for internet protocol (IP) relay nodes. In particular, a plurality of IP headers in a packet and at least one tunneling protocol header can be compressed to facilitate efficient communications of packets between IP relay nodes and/or a donor access point. In addition, IP relay nodes can be limited in a number of upstream bearers and can provide a greater number of downstream bearers. In this regard, the IP relay nodes can compress headers for upstream packets related to one or more downstream devices utilizing disparate context identifiers for the upstream packets. Thus, the upstream packets can be distinguished from each other while sent over the same upstream bearer.

摘要： Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. Packet data convergence protocol (PDCP) layer communications from a user equipment (UE) can terminate at a donor evolved Node B (eNB) and vice versa. In this regard, a relay application protocol (RAPP) layer is defined to transport application layer control data among relay eNBs to facilitate appropriate routing. RAPP layer messages can be similar to control messages at other application layers, such as S1-AP, X2, etc., while additionally including a relay UE identifier for routing the messages among relay eNBs. In addition, RAPP layer messages can exclude other parameters normally defined in other application layers to protect security and encryption/decryption details.

摘要： Systems, methods and apparatuses are provided that facilitate selecting resources, such as time slots, subframes, etc., for performing bandwidth switching related to activating and/or deactivating one or more carriers. A data portion of one or more subframes can be selected for performing bandwidth switching. In addition, a device can determine whether one or more downlink grants are received in the one or more subframes, and can avoid selecting such subframes. The device can alternatively perform the bandwidth switching and request retransmission of the data portion. Additionally or alternatively, the device can determine a type of the one or more subframes and/or signals transmitted in the one or more subframes to determine whether to perform bandwidth switching in the subframes. The bandwidth switching can include changing a sampling rate, reconfiguring frequency filters, modifying a local oscillator, etc.

摘要： Techniques for determining resources to use for peer-to-peer (P2P) communication are disclosed. In an aspect, a network entity may receive feedback information (e.g., resource usage information and/or channel state information) from P2P devices and may perform resource partitioning based on the feedback information to allocate some of the available resources for P2P communication. The allocated resources may observe little or no interference from devices engaged in wide area network (WAN) communication. In another aspect, P2P groups may perform resource negotiation via a WAN connection (e.g., with little or no involvement by the WAN) to assign the allocated resources to different P2P groups. In yet another aspect, a device may autonomously determine whether to communicate with another device directly or via a WAN, e.g., whether to initiate P2P communication with another device and whether to terminate P2P communication. In yet another aspect, a network entity may participate in resource negotiation by P2P devices.
摘要翻译： 公开了用于确定用于对等（P2P）通信的资源的技术。 在一方面，网络实体可以从P2P设备接收反馈信息（例如，资源使用信息和/或信道状态信息），并且可以基于反馈信息来执行资源划分，以分配用于P2P通信的一些可用资源。 分配的资源可能观察到从事广域网（WAN）通信的设备的干扰很小或没有。 在另一方面，P2P组可以经由WAN连接进行资源协商（例如，很少或没有WAN的参与）来将分配的资源分配给不同的P2P组。 在另一方面，设备可以自主地确定是直接地还是经由WAN与另一设备进行通信，例如是否发起与另一设备的P2P通信以及是否终止P2P通信。 另一方面，网络实体可以参与P2P设备的资源协商。
