Abstract: System, methods, and apparatus are described for transmitting encoded bits over a bus by conditionally embedding dynamically shielded information, in an example, the apparatus transmits a first group of encoded bits over a bus, generates a second group of encoded bits to be transmitted over the bus, where a first subset of the second group of encoded bits are encoded to avoid crosstalk-inducing bit transitions on adjacent lines of the bus, and configures one or more encoded bits of a second subset of the second group of encoded bits to ensure that the second group of encoded bits includes parity information and/or clock information, while further ensuring that crosstalk-inducing bit transitions in the second group of encoded bits are avoided.

Abstract: System, methods, and apparatus are described that facilitate transmission/reception of data over a multi-line parallel bus. In an example, the apparatus selects from a sequential series of data bits a plurality of data bits for transmission over a plurality of parallel bus lines. For each bus line of the plurality of parallel bus lines, the apparatus compares a state of a current data bit selected for transmission on a current bus line during a current clock cycle with one or more conditions related to the current bus line or at least one bus line adjacent to the current bus line, wherein the one or more conditions includes a state of two data bits respectively transmitted on two bus lines adjacent to the current bus line during a previous clock cycle, and determines whether to transmit the current data bit on the current bus line based on the comparison.

Abstract: Disclosed embodiments pertain to a method on a UE may comprise determining a first absolute position of the UE at a first time based on GNSS measurements from a set of satellites. At a second time subsequent to the first time, the UE may determine a first estimate of displacement of the UE relative to the first absolute position using non-GNSS measurements. Further, at the second time, the UE may also determine a second estimate of displacement relative to the first absolute position and/or a second absolute position of the UE based, in part, on: the GNSS carrier phase measurements at the first time from the set of satellites, and GNSS carrier phase measurements at the second time from a subset comprising two or more satellites of the set of satellites, and the first estimate of displacement of the UE.

Abstract: A server generates a combination of symbols requested by a set of users in response to the symbols requested by each user in the set being cached by the other users in the set. A transmitter in the server multicasts the combination of symbols to the set of users based on a transmission deadline associated with the set of users.

Abstract: A first cache is provided to cache a first portion of a first block of digital content received over a network connection shared between a first user associated with the first cache and at least one second user. The first cache caches the first portion in response to the first user or the second user(s) requesting the first block. The first cache selects the first portion based on a fullness of the first cache, a number of blocks cached in the first cache, or a cache eviction rule associated with the first cache.

Abstract: A first source node transmits a first transmission vector formed by multiplying a vector of input values and an inverse of a transfer matrix that relates vectors transmitted from the first source node via a plurality of intermediate nodes to vectors received at a plurality of destination nodes. Each of the intermediate nodes transmits a vector formed by a linear operation performed on received vectors. The linear operation may be determined based on linear combinations of the first transmission vector and one or more second transmission vectors transmitted by second source nodes. The linear combinations are to be received at the destination nodes. The linear operation is chosen so that propagation of the first transmission vector through the intermediate nodes produces, at the destination nodes, predetermined linear combinations of the first transmission vector and one or more second transmission vectors transmitted by one or more second source nodes.

Abstract: Clock drift for range estimation between a first wireless device and a second wireless device is determine before such estimation, while acceptable communication between the first device and the second device is unavailable. While acceptable communication is unavailable, a relative clock drift ?01 between a relative wireless device and the first device is obtained by the second device; a relative clock drift ?20 between the second device and the relative wireless device is determined; and a relative clock drift ?21 between the second device and the first device is estimated based on the relative clock drift ?01 and the relative clock drift ?20. Once acceptable communication is available, a distance between the first device and the second device is estimated based on the relative clock drift ?21.

Abstract: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

The method also include determining location information for the mobile device based on the first information, the second information, and known positions of at least some of the multiple stationary wireless devices.

Abstract: A method for distributing information in a network includes independently selecting and sending segments of N files to a plurality of terminals through a network. One or more of the selected segments except a first segment are sent to a first number of the K terminals, and one or more of the selected segments except a second segment are sent to a second number of the K terminals. A first logical combination of segments is then generated and sent to the terminals. By logically combining the first logical combination with previously sent files, a new file not previously received may be recovered.

Abstract: In general, a capability for forwarding packets based on path encoding is presented. The capability for forwarding a packet based on path encoding may be configured to enable forwarding of a packet along a network path by determining a path encoding label for the network path, associating the path encoding label for the network path with the packet, and forwarding the packet along the network path based on the path encoding label associated with the packet. The network path for a packet may include an ordered sequence of node output interfaces of an ordered sequence of nodes. The path encoding label for the network path includes an ordered sequence of node interface labels corresponding to the ordered sequence of node output interfaces of the nodes of the network path. The nodes of the network path forward the packet along the network path based on the path encoding label.
