Abstract: A large volume of location related information, e.g., assistance data or location information, is transferred in separate messages between a server and a target by segmenting the location related information into a plurality of messages. If the connection between the server and target is released prior to completion of the transfer of the location related information, the transfer is resumed by sending the remaining messages after connection is reestablished. Each message is sent after receiving an acknowledgement of receipt. Thus, both the server and target can control the flow of the transfer by delaying the sending of one or more messages or delaying the sending of the acknowledgements of receipt.

Abstract translation: 通过将位置相关信息分割成多个消息，大量的位置相关信息（例如辅助数据或位置信息）在服务器和目标之间的分离的消息中被传送。 如果服务器和目标之间的连接在完成位置相关信息的传送之前被释放，则在连接被重新建立之后通过发送剩余的消息来恢复传送。 每个消息在收到收到确认后发送。 因此，服务器和目标都可以通过延迟发送一个或多个消息或延迟发送接收确认来控制传送流。

Abstract: Examples are disclosed for simultaneous transmitting and receiving packets in a wireless local access network (WLAN). In some examples, a source node in the WLAN may transmit a packet to a destination node in the WLAN and may receive an implicit acknowledgement (ACK) packet from the destination node. The source node may stop transmitting a remaining portion of the packet if the implicit ACK packet is not received within a defined time interval or if a dummy/packet payload for the implicit ACK packet is not successfully decoded. Also, the destination node may or may not include a data payload in an implicit ACK packet sent responsive to receiving the packet from the source node. Other examples are described and claimed.

Abstract translation: 公开了用于在无线本地接入网络（WLAN）中同时发送和接收分组的示例。 在一些示例中，WLAN中的源节点可以向WLAN中的目的地节点发送分组，并且可以从目的地节点接收隐式确认（ACK）分组。 如果在规定的时间间隔内没有接收到隐式ACK分组，或者隐式ACK分组的虚拟/分组有效载荷未成功解码，则源节点可以停止发送分组的剩余部分。 此外，目的地节点可以或可以不包括响应于从源节点接收分组而发送的隐式ACK分组中的数据有效载荷。 其他的例子被描述和要求保护。

Abstract: A transport protocol is provided within a communication network that has a lossy link. The receiver distinguishes between packets received with non-congestion bit errors and packets having been not at all received due to congestion. When packets are received with non-congestion bit errors, the receiver sends selective acknowledgments indicating that the packets were received with bit errors while suppressing duplicate acknowledgments to prevent the invocation of a congestion mechanism.

Abstract: A method in a terminal for providing an ACK/NAK message to a base station is provided. The terminal counts the number of assigned downlink subframes detected from the base station resulting in k. The terminal then establishes whether each of a number of transport blocks comprised in the counted k downlink subframes is correctly received or not. In the case when each one of the transport blocks, comprised in the k downlink subframes is estimated as correctly received the terminal provides to the base station an encoded ACK message for the k subframes, which comprises k, the number of subframes.

Abstract: Methods and apparatus for implementing notification by network elements of packet drops. In response to determining a packet is to be dropped, a network element such as a switch or router determines the source of the packet and returns a dropped packet notification message to the source. Upon receipt of notification, networking software or embedded hardware on the source causes the dropped packet to be retransmitted. The notification may also be sent from the network element to the destination computer to inform networking software or embedded logic implemented by the destination computer that the packet was dropped and notification to the source has been sent, thus alleviating the destination from needing to send a Selective ACKnowledge (SACK) message to inform the source the packet was not delivered.

Abstract: A apparatus and method for transmitting channel state information is disclosed. If an LTE-A system transmits a reference signal per subframe to support eight transmitting antennas, a problem occurs in that overhead is great. In order to solve this problem, a reference signal for channel measurement is transmitted per subband at different periods, or a user equipment scheduled for channel measurement uses a demodulation reference signal. The user equipment can notify a base station of channel measurement result using the demodulation reference signal in accordance with implicit or explicit signaling from the base station.

Abstract: Systems and methodologies are described that facilitate communication by supplying an immediate re-send of an assignment, when such assignment is not decoded by an access node (“AN”). In one embodiment, the assignment to AT can be re-sent immediately, hence mitigating a requirement for the AT to indicate that “Yes” the assignment was received, or “No” that the assignment was not received. Accordingly, if the AN does not decode the assignment, the assignment is re-sent, and a request latency can be removed.

Abstract translation: 描述了当这种分配不被接入节点（“AN”）解码时，通过提供分配的立即重新发送来促进通信的系统和方法。 在一个实施例中，可以立即重新发送对AT的分配，从而减轻对AT指示“是”接收到分配的要求，或者“否”指示未被接收。 因此，如果AN不解码分配，则重新发送分配，并且可以去除请求等待时间。

Abstract: This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de) activation of downlink component carrier (s) configured for a base station and a mobile terminal. To enable efficient and robust (de) activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e. indicate which downlink component carrier (s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.

Abstract: A method of telecommunication transmits blocks of data between a user equipment and a station using parallel hybrid automatic repeat request processes. The station includes a scheduler that signals to the user equipment allocations of resources and parameters for transmission and re-transmission of the data blocks and a set of reception buffers that receive and re-order the data blocks from the user equipment. The scheduler assigns a reception index to the corresponding scheduled reception and assigning reception buffers to received data blocks as a function of the respective originally scheduled reception indexes identifying time slots scheduled for reception. A data block newly transmitted by the user equipment and received in its scheduled time slot is assigned to the reception buffer corresponding to the new reception index. A data block that is re-transmitted by the user equipment and received in a time slot later than its originally scheduled time slot is assigned to the reception buffer corresponding to the same reception index as its originally scheduled reception. The data blocks to which the scheduler assigns a reception index and a reception buffer of the set are Media Access Control Packet Data Units (‘MAC PDUs’).
