Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a configuration method of a multiple access resource set, a network device, and a terminal.
Background
One transmission method in the 5G NR standard is a transmission method (transmission with configured grant) based on pre-scheduling/non-scheduling/grant-free, and the base station is configured in advance for transmitting related parameters through RRC (radio resource control) signaling. The user transmits data on the pre-scheduled time frequency resource by adopting the pre-configured transmission parameters directly or in a mode of triggering through an L1 signal without sending a Scheduling Request (SR) and waiting for a dynamic Scheduling signaling, thereby reducing the data transmission delay and the control signaling overhead required by the dynamic Scheduling.
On the other hand, the Multiple Access methods adopted in the 4G LTE system and the current version of the 5G NR standard are both Orthogonal Multiple Access, for example, SC-FDMA (Single-carrier Frequency-Division Multiple Access) or OFDMA (Orthogonal Frequency Division Multiple Access) is adopted in the uplink in 5G, and OFDMA is adopted in the downlink.
Currently, Non-Orthogonal Multiple Access (NOMA) technology is receiving wide attention, and the 5G NR standard is also discussing a transmission scheme combining NOMA technology, wherein the combination of pre-scheduling/Non-scheduling/grant-free transmission and NOMA technology can further increase the number of users served on the same time-frequency resource, improve spectrum efficiency, and improve system robustness under user collision conditions.
Currently, NOMA is in the 3GPP standardized SI research stage, various schemes have not converged, and different NOMA schemes can be summarized as follows: the bit level processing mode comprises the following steps: an interleaver or scrambler; the symbol-level processing includes: multidimensional modulation, linear spreading, power allocation, etc. In the face of such numerous NOMA schemes, there is no relevant solution at present how to realize flexible configuration and use of multiple access resources.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for configuring a multiple access resource set, where the method is applied to a network device supporting non-orthogonal multiple access scheduling-free transmission, and the method includes:
Specifically, the first configuration information may be sent to the terminal through a first radio resource control RRC signaling, and the second configuration information may be sent to the terminal through a second radio resource control RRC signaling.
