Title:
METHODS FOR SCRAMBLING AND DESCRAMBLING, NETWORK DEVICE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/027910
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are methods for scrambling and descrambling, comprising: a network device generates a scrambling sequence for a first physical downlink control channel (PDCCH), wherein the first PDCCH is used for bearing energy-saving information; the scrambling sequence is generated according to a first radio network temporary identifier and a first parameter; the first parameter comprises at least one of a physical layer cell identifier, a cell radio network temporary identifier, and a first scrambling parameter; the first radio network temporary identifier is specific for the PDCCH for bearing energy-saving information; and the first scrambling parameter is a scrambling parameter of a demodulation reference signal of a PDCCH of a control resource set CORESET where the first PDCCH is located. The network device scrambles the first PDCCH according to the scrambling sequence and then sends same, and the terminal device descrambles the first PDCCH according to the scrambling sequence. According to the technical solution provided by the present application, the detection performance of the first PDCCH is improved.
