Title:
DOWNLINK MULTI-USER SUPERPOSITION TRANSMISSION METHOD AND APPARATUS, STORAGE MEDIUM AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2018/223841
Kind Code:
A1
Abstract:
Disclosed are a downlink multi-user superposition transmission method and apparatus, a storage medium and a program product. The method is applied to a network device, and comprises: based on a specified channel code set and a pre-set capacity threshold, respectively allocating, to M terminal devices, sets of information to be sent; based on message contents respectively sent to the M terminal devices, and the sets of information to be sent, which are respectively allocated to the M terminal devices, constructing a sequence of bits to be sent; and encoding, by means of a specified polar code encoder, the message bits to be sent so as to obtain code words to be sent, and respectively sending, to the M terminal devices and on a specified channel resource, the code words to be sent, wherein the specified channel resource is a channel resource used for the superposition transmission of messages of a plurality of terminal devices. According to the present application, terminal devices are distinguished between by means of the division of information sets, thus preventing a network device from needing to carry out fine power control and greatly reducing the detection time delay and the complexity of the terminal devices.
