Physical (PHY) layer solutions to support use of mixed numerologies in the same channel
A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The PSS and SSS may be received in a resource block of a cell and the resource block may have a first numerology. Further, the first numerology may have a first subcarrier spacing, while other resources of the cell at a same time as the resource block may have a second numerology with a different subcarrier spacing than the first numerology. In addition, the WTRU may determine synchronization based on the PSS and SSS. Also, the WTRU may receive a second signal in the cell, and the second signal may have the second numerology. Moreover, the WTRU may transmit user data. In a further example, the WTRU may search a frequency raster for the PSS and the SSS.

SELECTIVE MAPPING OF CODED MULTI-CHANNEL TRANSMISSION
The present invention provides methods, apparatus and systems for improving a systems-level data rate on a communications link such as the orthogonal frequency division multiplexed multiple access (OFDMA) downlink used in WiFi and LTE cellular/wireless mobile data applications. The present invention preferably uses a form of multilevel coding and decoding known as tiled-building-block encoding/decoding. With the present invention, different receivers coupled to different parallel downlink channels with different channel qualities decode different received signal constellations at different levels of resolution. This allows the downlink of the OFDMA system to operate with a significantly higher data rate, thus eliminating existing inefficiencies in the downlink and significantly increasing system level bandwidth efficiency.

Method and Apparatus for using Microslices to Control Network Performance of an Enterprise Wireless Communication Network
A method and apparatus for utilizing microslices in an enterprise wireless communication network to manage and control network performance. The microslice instances are monitored during network operation, for example at communication nodes, functional blocks, and end-to-end to provide Key Performance Indicators (KPIs). These KPI are compared with performance objectives, which may be Service Level Objectives (SLOs). If the performance objectives are not met by the KPIs, then one or more of the microslice instances may be dynamically adjusted until the performance objectives are sufficiently met. Alternatively, the lower priority microslice instances may be dropped (i.e., terminated) until the performance objectives are sufficiently met.
NR peak rate and transport block size
According to certain embodiments, a method is disclosed for operating a user equipment. The method comprises transmitting or receiving a transmission on at least one of the component carriers, wherein the at least one component carrier is associated with a slot duration that corresponds to a numerology of the component carrier. The transmitting or receiving on the at least one of the component carriers is based on a relation between a number of information bits on the at least one of the component carriers over one or more reference slot durations and a reference data rate.
OUTER CODING TECHNIQUES IN WIRELESS COMMUNICATIONS
Methods, systems, and devices for wireless communications are described that provide for a transmitter (e.g., a user equipment (UE) or base station) and receiver (e.g., a UE or base station) to transmit and receive data packets that are encoded according to an outer coding technique. The outer coding technique may provide for data bits and parity bits to be included in a single physical layer transmission. In some cases, data packets (e.g., data bits) may be segmented into multiple subpackets, and coding may be performed across different subpackets of different data packets (e.g., in a diagonal coding pattern). In some examples, each transmission in the physical layer may contain both data subpackets and parity subpackets, which may balance an input and an output load of a buffer (e.g., a layer two (L2) decoding buffer at the receiver) during decoding.
