Embodiment 1

[0083] Embodiment 1 is aimed at the above method 1, that is, the scene where the time of the indication signal is known in advance.

[0084] The terminal determines the time at which the PDCCH corresponding to the detection of the advance indication signal is located according to the time gap and the time at which the advance indication signal is located (that is, the first time). Wherein, the time of the advance indication signal is configured by the network device, or determined according to the UE ID. Wherein, the PDCCH corresponding to the advance indication signal is the PDCCH that the advance indication signal indicates to be detected by the terminal.

[0085] Wherein, the terminal may calculate the time at which the advance indication signal is located according to the UE ID. Specifically, the identification information (UE ID) of the terminal is mapped to N downlink time slots, subframes or frames (N>0) through a certain function such as a hash function. Among them, ...

Embodiment 2

[0093] The second embodiment corresponds to the second method, that is, the scenario where the time of the PDCCH corresponding to the advance indication signal is known.

[0094] The terminal determines the time at which the advance indication signal is detected according to the time gap and the time at which the PDCCH corresponding to the advance indication signal is located (that is, the second time). Wherein, the time of the PDCCH corresponding to the advance indication signal is configured by the network device, or determined according to the UE ID. Wherein, the PDCCH corresponding to the advance indication signal is the PDCCH that the advance indication signal indicates to be detected by the terminal.

[0095] Wherein, the terminal calculates the time of the PDCCH corresponding to the advance indication signal according to the UE ID, specifically: map the terminal identifier (UE ID) to N downlink time slots or subframes through a function such as a hash function (N>0 ); ...

Abstract

The invention discloses an information detection method, a transmission method, a terminal and a network device. The method comprises: acquiring the time gap between the first moment and the second moment; The current moment of the PDCCH. Wherein, the first time is the time at which the advance indication signal is located, and the second time is the time at which the physical downlink control channel PDCCH corresponding to the advance indication signal is located. The present invention determines the time gap between the first moment and the second moment, and determines the advance indication signal or the time of the PDCCH corresponding to the advance indication signal according to the time interval, so that the terminal can detect at the corresponding time, reducing the number of terminal delays. The complexity of blind detection.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information detection method, a transmission method, a terminal and a network device. Background technique [0002] In the fourth generation (4 th Generation, 4G) and the fifth generation (5 th Generation, 5G) communication system, in order to further save the power consumption of blind detection of paging (Paging) signal or physical downlink control channel (Physical Downlink Control Channel, PDCCH) in the scenario of discontinuous reception (Discontinuous Reception, DRX), propose Based on the concepts of wake-up signal (wake-up signal, WUS) and sleep signal (Go To Sleep Signal, GTS), the detection of WUS or GTS is less complex and more power-saving than blind detection of Paging signal or PDCCH. Although the WUS or the GTS can indicate whether to detect the PDCCH in the next DRX cycle, it cannot determine when the WUS, the GTS and the PDCCH indicated by it...
