Abstract: A method embodiment includes implementing, by a base station (BS), a grant-free uplink transmission scheme. The grant-free uplink transmission scheme defines a first contention transmission unit (CTU) access region in a time-frequency domain, defines a plurality of CTUs, defines a default CTU mapping scheme by mapping at least some of the plurality of CTUs to the first CTU access region, and defines a default user equipment (UE) mapping scheme by defining rules for mapping a plurality of UEs to the plurality of CTUs.

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 TTI 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: A network for facilitating wireless radio communication. The network includes a first access area, wherein the access area includes one or more transmission/receive points. At least one transmission/receive point includes a base station that supports wireless communication between a network and user equipment (UE), such as, a mobile device. The network includes a dedicated connection signature (DCS) that is assigned to a UE. The DCS provides for and is used by the UE to maintain active, unified access to the wireless network. More particularly, the DCS provides for active, contention free, and fast access for the UE to the network through transmission/receive points within the first access area, which is of significance to present and future UE centric virtual radio access networks having high densities of mobile and non-mobile users and with high populations of different types of traffic patterns and applications.

Abstract: A method for operating a transmission point in a communications system includes receiving wideband feedback information at a first report rate, and receiving subband feedback information at a second report rate, wherein the first report rate is less than the second report rate. The method also includes performing dynamic rate selection for resource block groups (RBGs) of the communications system in accordance with the wideband feedback information and the subband feedback information.
