Abstract: A system and method for decoding an intended transmission includes a user device that receives a downlink transmission containing a user signal intended for the user device and one or more interfering user signals directed to one or more other user devices. The user device obtains power stacking information that includes a power level for each of the user signals contained in the received downlink transmission. A channel is estimated using pilot signals in the downlink transmission. Each interfering user signal contained in the downlink transmission is demodulated and decoded using the power stacking information. The user device removes all interfering user signals from the received downlink transmission to obtain the user signal intended for the user device.

Abstract: A wireless access point can identify a group of service providers that can provide access for respective subscriber devices. The wireless access point can periodically monitor its network traffic load. In response to determining that the amount of the network traffic load is above a threshold amount, the wireless access point selects one or more service providers from the group, and impedes use of each of the selected one or more service providers from the wireless access point by one or more additional subscriber devices that have not yet connected to the wireless access point.

Abstract: For a system providing coexistence between a WPAN coordinator and WLAN Access Point (AP), the WPAN coordinator requests WLAN AP for WPAN operation in a selected WLAN channel. The WLAN AP responds with the allocated time limit for which the WPAN operation can be performed. After expiration of the allocated time limit, the WPAN coordinator relinquishes the channel to the WLAN AP. A method addresses the operation of the WPAN system in 2.4 GHz ISM band when a non-overlapping WPAN channel selection is infeasible.

Abstract: User equipment communicating with a telecommunications network may be configured to selectively initiate a communication session with another device via a first access network of a first type. During a pre-establishment phase, the user equipment may measure the first access network to provide a first measurement. In response to the first measurement corresponding to a first service-interruption condition, the user equipment may cancel the communication session, tune a radio of the user equipment to communicate with a second access network of a second, different type, and re-initiate the communication session with the other device via the second access network. The user equipment may, after the canceling, receive a retry invitation to the communication session via the second access network, tune the radio thereto, and re-initiate the communication session with the other device via the second access network.

Abstract: Exemplary embodiments identify all viable paths in an ECMP/WCMP enabled network without running traceroute multiple times. Devices in a network may be configured to send a packet including a pre-determined option to a Software-Defined Network Controller (SDNC) upon receipt. If a destination of the packet is within the SDNC-controlled domain, SDNC identifies all viable ECMP/WCMP paths using routing information of the network. If the destination of the packet is outside the SDNC-controlled domain, SDNC identifies at least one egress switch of the SDNC-controlled domain. SDNC may identify internal paths connecting the source of the packet to the at least one egress switch. SDNC may also identify external paths connecting the at least one egress switch to the destination of the packet. SDNC may construct the viable ECMP/WCMP paths by connecting the internal paths to the external paths.

Abstract: A guard period for switching between uplink and downlink subframes is created by shortening a downlink subframe, i.e., by not transmitting during one or more symbol intervals at the end of the subframe. A grant message includes signaling indicating when a shortened subframe is being transmitted. An example method is implemented in a receiving node configured to receive data from a transmitting node in subframes having a predetermined number of symbol intervals. In an LTE system, this receiving node may be a UE, and the subframes are downlink subframes. This example method includes determining 1120 that a received subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, disregarding 1130 a last part of the received subframe by disregarding one or more symbols at the end of the received subframe when processing the received subframe.

Abstract: Some embodiments provide an elastic architecture for providing a service in a computing system. To perform a service on the data messages, the service architecture uses a service node (SN) group that includes one primary service node (PSN) and zero or more secondary service nodes (SSNs). The service can be performed on a data message by either the PSN or one of the SSN. However, in addition to performing the service, the PSN also performs a load balancing operation that assesses the load on each service node (i.e., on the PSN or each SSN), and based on this assessment, has the data messages distributed to the service node(s) in its SN group. Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group.
