Abstract: Methods and devices are provided for communicating data in a wireless channel. In one example, a method includes adapting the transmission time interval (TTI) length of transport container for transmitting data in accordance with a criteria. The criteria may include (but is not limited to) a latency requirement of the data, a buffer size associated with the data, a mobility characteristic of a device that will receive the data. The lengths may be manipulated for a variety of reasons; such as for reducing overhead, satisfy quality of service (QoS) requirements, maximize network throughput, etc. In some embodiments, TTIs having different TTI lengths may be carried in a common radio frame. In other embodiments, the wireless channel may partitioned into multiple bands each of which carrying (exclusively or otherwise) TTIs having a certain TTI length.

Abstract: Virtualized group-wise communications between a wireless network and a plurality of user equipments (UEs) are supported using UE cooperation. UE cooperation includes receiving, at a cooperating UE (CUE), downlink information from the wireless network destined for a target UE (TUE) and associated with a group identifier (ID). The group ID indicates a virtual multi-point (ViMP) node that includes the TUE and the CUE. The UE cooperation also includes sending the downlink information to the TUE. The UE or UE component can have a processor configured to forward between the wireless network and a TUE at least some information that is associated with a group ID indicating a ViMP node that groups the TUE and the UE.

Abstract: System and method embodiments are provided for enabling flexible and reliable UE-to-UE based relay. The embodiments include using fountain codes for combining signals at a suitable network layer higher than a media access control (MAC) sub-layer and using a MAC sub-layer hybrid automatic repeat request (HARQ) transmission scheme. When a relay UE in a UE group for joint reception receives, from a network access point, a data packet intended for a destination UE in the UE group and including fountain code at the higher network layer, the relay UE sends the data packet to the destination UE and returns a HARQ ACK message at the MAC sub-layer to the access point. The destination UE then receives and decodes the data packet. Subsequently, upon receiving the entire data, the destination UE sends an ACK message at the higher network layer to the access point.

Abstract: Signal processing complexity in fifth generation (5G) networks can be reduced by communicating wireless signals over self-contained partitions of a carrier such that the wireless transmission communicated over each self-contained partition of the carrier includes all physical control channel signaling required to decode data carried in a physical data channel of the partition. The control signaling may include resource assignment within the partition, modulation and coding scheme indication, reference signal configuration and retransmission information. In some embodiments, an anchor partition of a carrier is used to communicate initial access information for self-contained partitions of the carrier. The initial access information may include center-frequencies, bandwidths, and/or air interface configurations of the self-contained partitions. The anchor partition may also carry load indications associated with the self-contained partitions.

Abstract: A system including a cell controller and a method for dynamic inter-cell interference coordination based on a strong interference neighbor relationship table (SI-NRT) are provided. In the method, the cell controller generates a SI-NRT based on a predefined threshold value and interferences from a plurality of neighbor cells. The cell controller determines whether a cell needs additional high power frequency band and determines whether there is available high power frequency band in the plurality of neighboring cells based on the SI-NRT.
