  • Patent number: 9641236
    Abstract: Some embodiments provide a method in a wireless device for reporting channel state information, CSI, for a CSI process. The CSI process corresponds to a reference signal resource and an interference measurement resource. According to the method, the wireless device obtains an adjustment value associated with the CSI process. The wireless device estimates an effective channel based on one or more reference signals received in the reference signal resource, and applies the adjustment value to the estimated effective channel, thereby obtaining an adjusted effective channel. Furthermore, the wireless device determines channel state information based on the adjusted effective channel, and on interference estimated based on the interference measurement resource. Finally, the channel state information is transmitted to a network node.

  • Patent number: 9609035
    Abstract: A system performs tunneling for real time communication (“RTC”) between a source endpoint and a destination endpoint. The system receives, by a server, a request from a user equipment (“UE”) for enabling header compression of inner internet protocol (“IP”) and transport headers of media traffic encapsulated within a tunnel. The media traffic corresponds to the RTC between the source endpoint and the destination endpoint. The system determines a mapping that maps one or more indices to identifying information of the source endpoint and the destination endpoint, and sends a response to the UE including the mapping. Upon sending the response, the UE and the server communicate the media traffic according to the mapping, where the media traffic includes media packets in which inner IP and transport headers are replaced with an index within the one or more indices.

  • Patent number: 9590791
    Abstract: Uplink control channel management is disclosed in which a user equipment receives a configuration for multiple uplink control channels for transmission to multiple nodes in multiflow communication with the UE. The UE generates the uplink control channels based on the configuration, wherein each of the uplink control channels is generated for a corresponding one of the nodes. The UE then transmits each of the uplink control channels to the corresponding node. For UEs capable of multiple uplink transmissions, in which the UE communicates with at least one of the nodes over multiple component carriers (CCs), the configuration may designate with of the multiple CCs the UE should transmit the uplink control channel for that node. For UEs capable of only single uplink transmissions, the configuration may designate the transmission of the uplink control channels in either frequency division multiplex (FDM) or time division multiplex (TDM) schemes.
