Abstract: An override subsystem on the host side of a serial data link between the host and a peripheral detects and diagnoses link errors by comparing the states of the port's link-layer component and physical layer. An override controller accesses a data-store containing stored policies for responding to particular errors. After selecting the appropriate policy, the override controller takes control of the physical layer, the link-layer component, or both, reconfigures them according to the policy to correct the errors, and returns control of the physical layer to the host controller and link-layer component. As well as error recovery, the override subsystem may be used by applications or drivers to asynchronously manage power consumed by the link.

Abstract: Disclosed is a method and system for offset decoding of resource elements in a resource block to compensate for propagation delay in uplink coordinated multipoint service. A determination may be made that the initial data symbol of a time-ordered sequence of N data symbols transmitted by a user equipment device (UE) to a base station (BS) will be received at an arrival time beyond an initial one of N equally-spaced tolerance windows for simultaneous decoding of data symbols received from UEs. If it is determined that the arrival time will be within a subsequent one of the N equally-spaced tolerance windows, then the BS may receive and decode those of the N data symbols with respective arrival times in one of the subsequent tolerance windows. Otherwise, the BS may refrain from decoding any of the N data symbols. The decode data symbols may be merged with those from another BS.

Abstract: A method for performing robust header compression (ROHC) of request for comments (RFC) 3095 over a packet data convergence protocol (PDCP) layer to compress and decompress voice over long term evolution (VoLTE) packets is provided. In the voice call operation, an evolved node B (eNB) receives an initialization and refresh (IR) packet transmitted by a user equipment (UE) and performs ROHC compression/decompression on the voice packet with a compressed header based on the information contained in the received IR packet. If the IR packet is lost, the eNB cannot establish the context for the voice packet, resulting in ROHC operation failure and a call drop problem. In order to maintain the voice call, the eNB sends the UE a static negative acknowledgement (SNACK) when a voice packet is received in the state where no context exists.

Abstract: Battery power of a dual radio (e.g., Wi-Fi and cellular radios) user equipment (UE) is conserved based on limiting simultaneous (or substantially simultaneous) usage of the radios based on user preference, cellular network condition, device speed, and/or network operator policies. In one aspect, the UE can receive, by employing a first radio (e.g., cellular radio), an adaptable signal strength criterion related to real-time network load conditions of a first radio access network (e.g., cellular network). Moreover, if the signal strength criterion is satisfied, the UE can switch on a second radio (e.g., Wi-Fi radio) to facilitate connection with a second radio network (e.g., Wi-Fi network). The signal strength criterion is updated such that second radios of UEs that are located closer to a cell edge of the first radio access network are switched on before switching on second radios of UE that are located closer to the serving access point.
