Methods of segmentation and concatenation for new radio user plane are proposed. For high speed data traffic, all PDCP PDUs are segmented into fixed-length segments at RLC layer. The MAC layer can then concatenate these segments based on real time uplink grants. Under this mechanism, segmentation related header fields can be pre-computed since they are not dependent on the uplink grant process. For low data rate with small packet size traffic, a solution of PDCP layer concatenation is proposed to reduce protocol overhead. Multiple PDCP SDUs are concatenated into a single PDCP PDU. The level of PDCP concatenation is configured by the base station or implemented by the UE.

Described is an apparatus of a first User Equipment (UE) operable to communicate with on a wireless network. The apparatus may comprise a first circuitry, and a second circuitry. The first circuitry may be operable to establish a parameter set defining 5G Physical Downlink Control Channel (xPDCCH) transmission to the UE. The second circuitry may be operable to generate, for transmission to the UE, one or more messages including the parameter set.

Embodiments described herein provide a method for performing multi-level coding in a discrete multitone modulation (DMT) communication system. A plurality of data bits are divided into a first number of un-encoded bits and a set of bits to be encoded. The set of bits to be encoded are encoded into a second number of encoded bits. The first number is different from the second number, and the first number is an even number or an odd number. The first number of un-encoded bits and the second number of encoded bits are mapped into a plurality of constellation points. The plurality of constellation points are transmitted as orthogonal frequency-division multiplexing (OFDM) symbols.

The present disclosure provides a method for selecting a modulation and coding scheme (MCS) and the number of resource blocks, comprising the following steps of: selecting, by a terminal apparatus, an MCS and the number of resource blocks for uplink data transmission according to power control information, channel state information, multiple access resource information, the size of a data packet and/or interference intensity information; and, partitioning resource blocks within a frequency band according to a pre-defined resource partitioning and mapping pattern, and transmitting data through the partitioned resource block combination, the partitioned resource block combination being corresponding to the selected MCS and the selected number of resource blocks.

Methods and apparatuses for communicating over a wireless communication network are disclosed herein. One example apparatus includes a memory that stores instructions. The apparatus further includes a processor coupled with the memory. The processor and the memory are configured to determine a total bandwidth for a transmission of a message, the total bandwidth including a plurality of tones. The processor is further configured to divide the plurality of tones in the total bandwidth into one or more 26-, 52-, 106-, 242-, or 996-tone blocks. The processor is further configured to determine an indication. The indication assigns one or more of the one or more tone blocks to a first wireless communication device. The apparatus further includes a transmitter configured to transmit the indication to at least the first wireless communication device or a second device.

A method of providing a configurable signaling (SIG) field is proposed to reduce the SIG overhead of a data packet in a wireless network. The SIG field comprises both HE-SIG-A field and HE-SIG-A2 field. HE-SIG-A field contains only necessary information for a default network scenario (e.g., indoor non-OFDMA SU-MIMO) to avoid HE-SIG-A2. HE-SIG-A2 field contains OFDMA, MU-MIMO, and/or outdoor parameter settings. By using HE-SIG-A to indicate the existence, mode, and/or length of HE-SIG-A2, the signaling overhead for default scenario can be reduced by avoiding the entire HE-SIG-A2 field. The number of symbols required for HE-SIG-A2 is adjustable based on each transmission scenario and indicated by HE-SIG-A. Further, because higher MCS such as QPSK may be supported for HE-SIG-A2, additional signaling overhead is reduced.

Apparatuses and methods for Non-Orthogonal Multiple Access (NOMA) communication are discussed. An example Evolved NodeB (eNB) includes a memory, a processor, and a transmitter circuit. The processor evaluates an orthogonal multiple access (OMA) metric and a NOMA metric, generates a protocol instruction that indicates an OMA transmission or a NOMA transmission based on the metrics, and determines a first modulation and coding scheme for a first UE and a second MCS for a second UE. The transmitter circuit receives the protocol instruction and transmits a first data signal and a first downlink control information (DCI) message associated with the first UE, and a second data signal and a second DCI message associated with the second UE. When the protocol instruction indicates NOMA transmission, the data signals are power multiplexed, the DCI messages indicate the data signals are transmitted via NOMA, and the first DCI message indicates the second MCS.
