Network architecture, methods, and devices for a wireless communications network

Abstract

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wirelesscommunications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology, where the first numerology has a first subcarrier spacing and the second numerology has a second subcarrier spacing, the first subcarrier spacing differing from the second subcarrier spacing. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

Description

technical field [0001] The present disclosure relates to wireless communication networks, and describes network architectures, wireless devices, and wireless network nodes suitable for, but not limited to, fifth generation (5G) wireless communication networks. Background technique [0002] So-called 5G wireless communication systems need to address three main challenges to realize a truly "connected society" in which anyone and anything can access information and share data anytime, anywhere. These main challenges are: [0003] - Massive growth in the number of connected devices. [0004] - Massive growth in business volume. [0005] - An increasingly wide range of applications with different requirements and characteristics. [0006] To handle the massive increase in traffic, wider frequency bands, new spectrum, and in some cases denser deployments are required. Most of the business growth is expected to be indoors, and therefore indoor coverage is important. [0007] ...
