  • Publication number: 20180295641
    Abstract: In some implementations, a method of wireless communications between a wireless communications network and wireless user equipment includes receiving, using a primary Time Division Duplex (TDD) configuration, data on a primary component carrier in a first frequency band. Using a secondary TDD configuration, data on a secondary component carrier is received in a second frequency band different from the first frequency band. A Hybrid Automatic Repeat Request (HARQ) for data received on the secondary component carrier is transmitted using a supplemental TDD configuration. A transmission or retransmission on the secondary component carrier uses a supplemental TDD configuration as well. The supplemental TDD configuration is different from the secondary TDD configuration. Furthermore, an uplink supplemental configuration may be different from a downlink supplemental configuration.

  • Patent number: 9520967
    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.

  • Patent number: 9521669
    Abstract: Systems, methods, and apparatuses are directed to reconfiguring a time division duplex (TDD) uplink/downlink (UL/DL) configuration. A first TDD UL/DL configuration can be identified for a first radio frame. A second TDD UL/DL configuration can be identified for a second radio frame adjacent the first radio frame. The second TDD UL/DL configuration can be identified based, at least in part, on one or more subframes of the second TDD UL/DL configuration that can communicate hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) indicators for corresponding subframes of the first TDD UL/DL configuration.
