Problems solved by technology

[0005] Embodiments of the present invention provide a method for monitoring PDCCH, a terminal and a network device, to solve the problem that the prior art does not limit the maximum processing capacity of the UE to blindly detect the PDCCH of a CC or a cell in the process of cross-carrier scheduling. Due to the limitation, the problem that it is impossible to reasonably configure the corresponding blind detection behavior for the UE

Embodiment 1

[0061] figure 2 It shows a schematic flowchart of a method for monitoring a PDCCH provided by an embodiment of the present invention, as shown in figure 2 As shown, the method for monitoring the PDCCH may include:

[0062] Step 201: The network device configures cell parameters of M cells for the terminal.

[0063] Correspondingly, the peer terminal receives the cell parameters sent by the network device to the terminal. Among them, the above-mentioned network equipment can be figure 1 A network device in the communication system shown, for example, a base station; the above-mentioned first terminal may be figure 1 Terminal equipment in the communication system shown.

[0064] Step 202: the network device sends the PDCCH to the terminal through the N scheduling cells.

[0065] Step 203: The terminal monitors the PDCCH according to the PDCCH blind detection capability information of the N scheduling cells.

[0066] In the embodiment of the present invention, the above-m...

Embodiment 2

[0076] image 3 It shows a schematic flowchart of another method for monitoring a PDCCH provided by an embodiment of the present invention, as shown in image 3 As shown, the embodiment of the present invention is mainly aimed at the scenario where the subcarrier spacing of M cells is the same. In this scenario, the method for monitoring the PDCCH may include:

[0077] Step 301: The network device configures cell parameters of M cells for the terminal.

[0078] Step 302: the network device sends the PDCCH to the terminal through the N scheduling cells.

[0079] Step 303: When the subcarrier spacing of the M cells is the same, the terminal obtains the first candidate PDCCH blind detection capability information and the second candidate PDCCH blind detection capability information of the first scheduling cell, and stores the first candidate PDCCH The minimum value of the blind detection capability information and the second candidate PDCCH blind detection capability informatio...

Embodiment 3

[0103] Figure 4 It shows a schematic flow chart of another method for monitoring PDCCH provided by the embodiment of the present invention. The embodiment of the present invention can be applied to any cross-carrier scheduling scenario (that is, not only applicable to the scenario where the subcarrier spacing of M cells is the same , is also applicable to the scenario where the subcarrier spacing of the M cells is not the same). Such as Figure 4 As shown, the method for monitoring the PDCCH may include:

[0104] Step 401: The network device configures cell parameters of M cells for the terminal.

[0105] In the embodiment of the present invention, the above cell parameters further include: first priority information of N scheduling cells and / or second priority information of M cells.

[0106] Step 402: The network device sends the PDCCH to the terminal through the N scheduling cells.

[0107] Step 403: According to the first priority information / or the second priority in...

Abstract

Embodiments of the present invention provide a method, terminal and network equipment for monitoring PDCCH, which relate to the field of communication technology and are used to solve the problem of blind detection of PDCCH of a CC or cell by UE in the process of cross-carrier scheduling in the prior art The maximum processing capability of the UE is limited, which leads to the problem that the corresponding blind detection behavior cannot be reasonably configured for the UE. The method includes: monitoring the PDCCH according to the PDCCH blind detection capability information of N scheduling cells; the N scheduling cells are cells in M ​​cells configured by the network equipment for the terminal, and the M cells also include: X scheduled cells; N The PDCCH blind detection capability information of scheduling cells is related to the cell parameters of M cells; the PDCCH blind detection capability information of N scheduling cells is used to indicate that the terminal performs PDCCH detection in each scheduling cell or N scheduling cells within a unit time. Maximum processing capacity of blind detection; M and N are positive integers greater than or equal to 1, X is a positive integer greater than or equal to 0, M=N+X.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, terminal and network equipment for monitoring a Physical Downlink Control Channel (PDCCH). Background technique [0002] At present, the 5G (NR) system supports configuring multiple control resource sets (Control Resource Set, CORESET) and multiple search space sets for each carrier (Component Carrier, CC) or cell configured for the user equipment (User Equipment, UE), And the number of PDCCH candidates is flexibly configured for each search space set. [0003] In the prior art, for single-carrier scheduling or self-scheduling configuration under carrier aggregation (Carrier Aggregation, CA), the existing protocol stipulates the maximum processing capability of the UE for blind detection of the PDCCH of a CC or cell. The maximum processing capability Including: the maximum number of PDCCH candidates for the UE to perform blind detection on the PDCC...
