Network Architecture, Methods, and Devices for a Wireless Communications Network

Smart overview of the Invention

The patent application details methods and apparatus for wireless communications, particularly in the context of fifth-generation (5G) networks. It describes a method in a wireless device that involves receiving a downlink signal with an uplink access configuration index, identifying an uplink access configuration from a set of configurations, and transmitting according to this configuration. Additionally, it involves receiving Orthogonal Frequency-Division Multiplexing (OFDM) transmissions formatted according to different numerologies in separate subframes.

Technical Field

This disclosure focuses on network architecture and wireless devices suitable for 5G networks. It addresses the challenges posed by the massive growth in connected devices, traffic volume, and diverse application requirements. Solutions involve using wider frequency bands and denser deployment to manage the expected traffic growth, especially indoors.

Methodology

The described method includes processing OFDM transmissions with different numerologies, each having distinct subframe lengths and subcarrier spacings. The method also involves handling Layer 2 data on multiple physical data channels with varying HARQ processes. A single Radio Resource Control (RRC) protocol layer may be used to process messages from different MAC protocol layers.

Network Operations

The method includes operating in connected and dormant modes, with specific tasks like monitoring tracking area identifiers during dormant intervals. It also involves transmitting capability pointers to the network and using contention-based access protocols such as listen-before-talk (LBT). Mobility reference signals are measured on different beams, aiding in optimizing beam switching commands.

Radio Network Equipment

The application also covers methods for radio network equipment, including transmitting downlink signals with uplink access configuration indices and handling OFDM transmissions with varying numerologies. Different instances of radio network equipment may perform these tasks, facilitating efficient communication between the network and wireless devices.
