example 1

[0071] Exemplarily, in conjunction with the above step C, the above step 204 specifically includes the following steps:

[0072] Step C1: If the terminal device monitors the second PDCCH, it determines that the target PDSCH contains updated system information.

[0073] Exemplarily, after the terminal device detects the second PDCCH in the target search space, it can determine that the target PDSCH contains updated system information.

example 2

[0075] Exemplarily, in the case where the above-mentioned target search space is at least one search space corresponding to the paging occasion (Paging Occasion) (that is, the Paging search space of the Paging Occasion), the above-mentioned step C specifically includes the following steps:

[0076] Step C2: When the terminal device monitors the first PDCCH in the target search space, it monitors the second PDCCH in the target search space.

[0077] Exemplarily, the terminal device monitors the first PDCCH and the second PDCCH in the same search space, and if the second PDCCH is detected, it determines that the target PDSCH scheduled by the second PDCCH contains updated system information.

example 3

[0079] Exemplarily, the above step C specifically includes the following steps:

[0080] Step C31: the terminal device receives first indication information from the network device.

[0081] Correspondingly, the peer network device sends the first indication information to the terminal device.

[0082] Step C32: The terminal device monitors the second PDCCH in the target search space in the case of monitoring the first PDCCH according to the first indication information.

[0083] Wherein, the above-mentioned first indication information is transmitted in the first PDCCH, and the above-mentioned first indication information is used to instruct to monitor the second PDCCH in the target search space. Exemplarily, the above target search space may be: predefined, or configured by the network device through system information or RRC signaling.

[0084]It should be noted that the above-mentioned target search space is different from conventional search spaces ib1 and searchspace O...

Abstract

The embodiment of the invention provides a determination method, terminal equipment and network equipment, relates to the technical field of communication, and aims to solve the problem of idle resource waste in the existing system information updating process. The method comprises the following steps: monitoring a second PDCCH under the condition of monitoring a first PDCCH, and determining whether a target physical downlink shared channel (PDSCH) contains updated system information or not according to the second PDCCH, wherein the first PDCCH is a PDCCH scrambled by a paging message wirelessnetwork temporary identifier P-RNTI, the second PDCCH is a PDCCH scrambled by a system message wireless network temporary identifier SI-RNTI and the target PDSCH is the PDSCH scheduled by the secondPDCCH.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a determination method, terminal equipment and network equipment. Background technique [0002] In the New Radio (NR) system, the network device will pass the Paging Physical Downlink Control Channel (Paging Physical Downlink Control Channel, Paging PDCCH) (that is, the paging message wireless network temporary identity (Paging-Radio Network Tempory Identity, P -RNTI) scrambled PDCCH) indicates system information update, if the network side indicates system information update, the user equipment (User Equipment, UE) needs to receive new system information within a modification period (modification period). [0003] Generally, Paging mainly includes two functions: 1) paging idle state UE; 2) instructing system information update. If a user is paged, the PDSCH scheduled by the Paging PDCCH contains the ID of the paged UE; if no user is paged and the system informati...
