Title:
USER EQUIPMENT GROUPING FOR UPLINK NON-ORTHOGONAL MULTIPLE ACCESS
Document Type and Number:
WIPO Patent Application WO/2020/024148
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. One or more non-orthogonal multiple access (NOMA) -capable user equipments (UEs) may be grouped together for transmitting uplink NOMA communications to a base station, where the UEs may be assigned to the group based on similar capabilities or service requirements. In some cases, when assigned to a group, the one or more NOMA-capable UEs may also receive a group-specific scrambling code for the uplink NOMA communications, a group-specific power control for the uplink NOMA communications, time and frequency resources to be used for the uplink NOMA communications specific to the group, or a combination thereof. Additionally, the specific time and frequency resources may be defined by one or more NOMA resource units, where each NOMA resource unit occupies a predefined number of orthogonal frequency division multiplexing symbols and a predefined number of physical resource blocks (PRBs) or sub-PRBs.
