Abstract: Base stations (BSs) can remove inter-BS interference components from received uplink signals using downlink information communicated over a backhaul network. The downlink information is associated with downlink transmissions of neighboring base stations, and is used to remove the inter-BS interference in accordance with interference cancellation techniques, e.g., signal interference cancellation (SIC), etc. The downlink information includes information associated with downlink transmission of the interfering BSs, such as information bits (e.g., data), parity information, control information, modulation and coding scheme (MCS) parameters, forward error correction (FEC) parameters, and other information. Additionally, inter-BS interference can be suppressed using channel information of interference channels using interference suppression techniques, e.g., interference rejection combining (IRC), etc.

Abstract: Historical decoding in accordance with signal interference cancellation (SIC) or joint processing may reduce the amount of data that is re-transported across a network following an unsuccessful attempt to decode a data transmission. In one example, historical decoding is performed in accordance with interference cancellation by communicating information related to interfering data (rather than information related to serving data) following a served receiver's unsuccessful attempt to decode an interference signal. The information related to the interfering data may be the information bits carried by the earlier interfering data transmission or parity information (e.g., forward error correction (FEC) bits, etc.) related to the earlier interfering data transmission.

Abstract: Fast mobile device authentication can be achieved during inter-domain handovers between administrative domains operating under a federated service agreement using pseudonym identifications (PID). Specifically, the mobile device may derive a PID when obtaining authentication in a first wireless network, and then use the PID to obtain fast authentication in a second wireless network. The PID may be generated during an Elliptic curve Diffie-Hellman (ECDH) authentication procedure using public keys associated with the mobile device and the first wireless network. The PID (or a derivative thereof) may then be provided to an authentication server in a second wireless network for validation. The PID may be validated by the second authentication server via online or offline validation procedures. The PID can also be used as an electronic coupon for accessing the second network.

Abstract: It is possible to achieve fast high-frequency link discovery by communicating location parameters identifying a spatial location of a mobile device over a low-frequency interface to a low-frequency access point (AP). The location parameters are then used to identify antenna configuration parameters (e.g., precoders, etc.) for communicating discovery signals between the mobile device and a high-frequency access point. In one embodiment, the low-frequency AP relays the location parameters to the high-frequency AP, which uses the spatial location of the mobile device to perform link discovery. In another embodiment, the low-frequency AP communicates high-frequency antenna configuration parameters to the mobile device over the low-frequency interface.

Abstract: There are disclosed systems, devices, and methods for distributing pre-fetch data. A parent node obtains pre-fetch data comprising at least one of: i) data expected to be of interest to a particular user, pre-fetched by the parent node from at least one data source; and (ii) at least one identifier identifying data expected to be of interest to the particular user, for pre-fetching the identified data at a child node. The parent node selects first and second subsets of the pre-fetch data for transmission, respectively, to first and second child nodes, the selecting based on at least a predicted future location of the particular user and a respective geographic location of the first and second child nodes; and transmits the first and second subsets of the pre-fetch data, respectively, to the first and second child nodes.

Abstract: Embodiments are provided for a location-based network discovery and connection establishment, which take advantage of location/positioning technology of user equipment (UE) and resolve issues above of the blind search approaches. The location-based network discovery and connection establishment schemes use UE location information and a network access MAP to speed up network discovery, and remove the need for continuous search and measurement by the UE. The schemes also reduce the search space. A wireless network access map (MAP) is provided to the UE. The UE uses the MAP information with UE current location information to reduce the search space and speed up network discovery and radio connection establishment with the network. Network operators can use this network access MAP to control the network access and manage the network load distribution. The network access MAP can be customized for each UE.

Abstract: Dynamic point selection (DPS) can be implemented using access points having partial or no DPS synchronization. Specifically, a mobile device may broadcast a bounce back message to access points participating in DPS transmissions to signal that a data segment has been successfully received and/or decoded by the mobile device. The bounce back message may cause the access points to drop remaining packets corresponding to the data segment from their buffers without sending those remaining packets over their respective radio interfaces. The bounce back message may be broadcast over any wireless signaling channel, such as via radio link control (RLC) signaling. Moreover, different priorities may be assigned to encoded packets intended for DPS transmission based on whether the encoded packets are communicated over a primary or secondary backhaul path.

Abstract translation: 可以使用具有部分或不具有DPS同步的接入点来实现动态点选择（DPS）。 具体地，移动设备可以向参与DPS传输的接入点广播反弹消息，以指示数据段已被移动设备成功接收和/或解码。 反弹消息可能导致接入点从其缓冲区中丢弃与数据段相对应的剩余数据包，而不会在其各自的无线电接口上发送剩余数据包。 反弹消息可以通过任何无线信令信道，诸如经由无线电链路控制（RLC）信令来广播。 此外，基于是否通过主或辅助回程路径传送编码的分组，可以将不同的优先级分配给用于DPS传输的编码分组。
