    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要翻译: 提出了一种提供可配置信令(SIG)字段的方法,以减少无线网络中的数据分组的SIG开销。 SIG字段包括HE-SIG-A字段和HE-SIG-A2字段。 HE-SIG-A字段仅包含用于避免HE-SIG-A2的默认网络场景(例如,室内非OFDMA SU-MIMO)的必要信息。 HE-SIG-A2字段包含OFDMA,MU-MIMO和/或户外参数设置。 通过使用HE-SIG-A来表示HE-SIG-A2的存在,模式和/或长度,通过避免整个HE-SIG-A2字段,可以减少默认情况的信令开销。 HE-SIG-A2所需的符号数量可根据每种传输情况进行调整,并由HE-SIG-A指示。 此外,由于HE-SIG-A2可以支持诸如QPSK的更高的MCS,所以额外的信令开销降低。

    摘要: 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.
