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 time division duplex (TDD) scheduling interval communicating transmissions in a first direction may include one or more regions for communicating in a second direction, where the first direction is a transmit direction and the second direction is a receive direction, or vice versa. A radio frame may include TDD scheduling intervals with such regions and/or TDD scheduling intervals without such regions for wireless communication, and these TDD scheduling intervals may further be configured in accordance with different frame structure configurations, such as different scheduling interval lengths, subcarrier spacings or symbol durations.

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: There is provided methods and apparatus to improve spectral efficiency in Hybrid Automated Repeat reQuest (HARQ) communications. New data and retransmission data is combined in packets using code domain multiplexing, where data layers carry data and retransmission layers carry retransmission data. This technique is leveraged to introduce Multi-Packet HARQ. The HARQ layers contain Incremental Redundancy (IR) bits to assist in the decoding of a subset of previously undecoded layers. Multiple packets are jointly decoded at the receiver. Using the properties of code multiplexing, and in particular Sparse Code Multiple Access (SCMA), the correct decoding of a subset of previously undecoded layers assists in the decoding of all previously undecoded layers. HARQ feedback for multiple packets is jointly interpreted by the receiver and the transmitter using state tables. These techniques are further leveraged to allow for Multiple-User SCMA.

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: In one embodiment, a method for adaptive transmission time intervals (TTIs) includes transmitting, by a communications controller to a user equipment (UE), a segment of a first TDD TTI configuration of a first TDD interval and a second TDD TTI configuration of the first TDD interval, where the first TDD TTI configuration has a first pattern, where the second TDD TTI configuration has a second pattern, where the first pattern is different than the second pattern, where the first TDD TTI configuration has a first uplink TTI segment and a first downlink TTI segment. The method also includes transmitting a first plurality of data on a first TTI in the first downlink TTI segment of the first TDD TTI configurations of the first TDD interval and receiving a second plurality of data on the first uplink segment of the first TDD TTI configuration of the first TDD interval.
