摘要： 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.

摘要： In some implementations, a method for dynamic cell clustering includes splitting, by an initial central coordinator, the cluster into two or more clusters in response to a message from a small cell in a cluster. The initial cluster includes a plurality of cells, including the small cell, with each cell assigned a same Time Division Duplex (TDD) configuration.

摘要： 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.

摘要： In some implementations, a method in a user equipment (UE) for supporting time division duplex (TDD) and frequency division duplex (FDD) joint carrier aggregation (CA) includes receiving a Physical Uplink Control Channel (PUCCH) resource allocation from an evolved NodeB (eNB). The PUCCH resource allocation includes a first PUCCH configuration for a first subframe and a second PUCCH configuration for a second subframe, and the second PUCCH configuration is different than the first PUCCH configuration. The UE transmits a first group of Hybrid Automatic Repeat reQuest (HARQ) bits based on the first PUCCH configuration in the first subframe. The UE transmits a second group of HARQ bits based on the second PUCCH configuration in the second subframe.
