  • Patent number: 8923274
    Abstract: A method for configuring a Time Division Duplex (TDD) Uplink/Downlink (UL/DL) allocation in a user equipment (UE) in a Long Term Evolved (LTE) network can include receiving, at a predefined period, during a connected state, each information block transmitted by an enhanced NodeB in the LTE network. Each information block may be transmitted in accordance with a fixed schedule having a predefined transmission period and includes information identifying a TDD configuration. Whether an updating of the TDD configuration is required can be determined for the UE based, at least in part, on the information identifying the TDD configuration in the information block, the information identifying the TDD configuration indicating an updated TDD configuration. In response to at least identifying the updated TDD configuration, the TDD UL/DL allocation of the UE can be automatically updated in accordance with the updated TDD configuration.

  • Patent number: 8923255
    Abstract: Systems, apparatuses, and methods of a wireless communications network include identifying a first downlink control channel. The possibility of an acknowledgement/negative acknowledgement (ACK/NACK) resource collision on a first uplink control channel is determined for a first component carrier and a second uplink control channel for a second carrier component. A second downlink control channel can be identified to avoid the ACK/NACK resource collision.

  • Publication number: 20140293883
    Abstract: Data is communicated between a network node and a user equipment in a first frame according to a first uplink-downlink configuration. In response to a configuration change that causes a second frame following the first frame to be according to a second, different uplink-downlink configuration, an acknowledgement indication for the data is sent in the second frame.

  • Publication number: 20140163464
    Abstract: Mixing devices and systems are disclosed for storing separate components and for mixing and dispensing those Components on demand. A mixing device includes a syringe having a generally tubular housing formed with a mixing chamber. A plunger is fitted to the tubular housing to form a first syringe. A dispensing syringe is releasably connected to the mixing chamber. At this point each syringe holds a desired amount of a mixture component. The contents of one syringe are passed through the mixing chamber to the other syringe, forming a usually incomplete mixture. The mixture is then passed through the mixing chamber to the other syringe. Multiple passes through the mixing chamber are continued until the desired mixing result is achieved, and the mixture material is contained in the second syringe that is used to thereafter dispense desired amounts of the mixture.

  • Publication number: 20140036749
    Abstract: Systems, methods, and user equipment can involve transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) bits for carrier aggregation between a first cell and a second cell in a User Equipment (UE). With the UE, for a sub-frame, a first number of ACK/NACK bits for the first cell can be compared with a second number of ACK/NACK bits for the second cell. If a first number of ACK/NACK bits for the first cell is less than a second number of ACK/NACK bits for the second cell, an ACK/NACK bit position from the first cell can be used to transmit an ACK/NACK bit for the second cell. In some implementations, one or more DTX bits can be used to set the number of ACK/NACK bits in the first cell equal to the number of ACK/NACK bits in the second cell.
