    Abstract: A User Equipment (UE) for sending feedback information is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE determines a primary cell (PCell) feedback parameter corresponding to a PCell. The UE also determines a secondary cell (SCell) feedback parameter corresponding to an SCell. The SCell feedback parameter is different from the PCell feedback parameter. The UE further performs Physical Uplink Control Channel (PUCCH) Format 1b channel selection based on the PCell feedback parameter and the SCell feedback parameter. The UE additionally sends Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) information based on the channel selection.

  • Patent number: 8942085
    Abstract: A multi-stage network may include a first stage having a first plurality of switches, a second stage having a second plurality of switches, and a number of links between the first and second stages. A controller in communication with the first plurality of switches and the second plurality of switches may determine a priority path to be utilized by each switch in sending information and a fallback path. If the priority path includes a failed link, the controller implements in one or more of the switches the fallback path for sending the information. The fallback path may, for example, cause the information to be transmitted through a peer router.

  • Patent number: 8934459
    Abstract: Maintaining time alignment with multiple carriers is contemplated. A group of uplink carriers (UL CC sets) that operate with a single Timing Advance (TA) may be determined, and a TA value may be applied to a specific UL CC set. A wireless transmit/receive unit's (WTRU) capability of using multiple TAs may define a group index of a few bits for each UL CC set. A TA Command received in a Random Access Response message may be used to apply the TA value to each UL carrier of the UL CC set. The WTRU may determine which UL CC set the TA value applies to based on which DL carrier the command was transmitted from. The WTRU may determine which UL CC set the TA value applies to based on the Group Index being explicitly provided in the command. The WTRU may release multi-CC configurations upon Time Alignment Timer (TAT) expiry.

  • Patent number: 8902887
    Abstract: This invention provides a load-balancing structure for packet switches and its constructing method. In this method, the structure based on self-routing concentrators is divided into two stages, that is, a first stage and a second stage fabric. A virtual output group queue (VOGQ) is appended to each input group port of the first stage fabric, and a reordering buffer (RB) is configured behind each output group port of the second stage fabric. Packets stored in the VOGQ are combined into data blocks with preset length, which is divided into data slices of fixed size, finally each data slice is added an address tag and is delivered to the first stage fabric for self-routing. Once reaching the RB, data slices are recombined into data blocks. This invention solves the packet out-of-sequence problem in the load-balancing Birkhoff-von Neumann switching structure and improves the end-to-end throughput.

  • Patent number: 8842559
    Abstract: The present invention relates to a solution for taking into account that the interference, which each of the transmission resource elements is affected by, may differ between the different transmission resource elements when determining an interference estimate by determining a mixed interference estimate, e.g. based on both reference symbols and data symbols. Furthermore, signalling from the network is also introduced which makes it possible to control what the mixed interference estimate should be based on.

  • Patent number: 8842589
    Abstract: A radio access network (RAN) may radiate to define a wireless coverage area that is configured to provide wireless coverage to wireless communication devices (WCDs). If the utilization of the wireless coverage area is below a low-utilization threshold, the RAN may begin transmitting noise frames in the wireless coverage area. In doing so, the transmitted signal strength of the wireless coverage area may increase, which in turn may increase the likelihood that the WCDs can acquire and use the wireless coverage area.
