Abstract

Claims (37)

1. A wireless communication method, comprising:

transmitting, by a network node to one or more communication nodes, the network node being a gNB and the one or more communication nodes being one or more user equipments (UEs), a set of parameters for selection of a multiple access transmission scheme from a plurality of multiple access transmission schemes,

wherein the plurality of multiple access transmission schemes includes an orthogonal multiple access (OMA) scheme and a non-orthogonal multiple access (NOMA) scheme, and

wherein the set of parameters for selection of the multiple access transmission scheme includes a single-bit indicator to indicate whether or not the NOMA scheme is enabled, and the set of parameters also includes a maximum number of transmissions that may be attempted using the NOMA scheme, wherein after reaching the maximum number of transmissions using the NOMA scheme, the one or more UEs are to use the OMA scheme, the single-bit indicator being included in a system information block transmitted by the network node; and

receiving, by the network node, data transmitted by a communication node using the multiple access transmission scheme selected by the communication node based on the set of parameters transmitted by the network node to the one or more communication nodes,
