Problems solved by technology

[0014] For the case where multiple Scells are activated in the downlink, multiple SCell scheduling can make data transmission more flexible, but before the Scell ​​timer times out or receives a deactivation command, the terminal needs to monitor the PDCCH of the activated Scell ​​all the time. The behavior depends on whether the secondary cell is activated, so the flexibility of listening is less

example 1

[0234] Example 1: Using 5-bit monitoring cell indication information

[0235] Base station side:

[0236] 1. By introducing PDCCH monitoring skip indication information in the scheduling DCI, it is used to indicate whether the terminal skips the PDCCH monitoring action for the Pcell or Scell. Each Scell ​​is indicated by the PDCCH monitoring indication information in the respective scheduled DCI.

[0237] 2. When the last data packet is scheduled, the base station sends a PDCCH monitoring indication to the terminal through the DCI, which is a non-zero bit value, and instructs the terminal to skip PDCCH monitoring. The DCI here includes the scheduling DCI of the Pcell and all activated Scells. For example:

[0238] 1) If the PDCCH monitoring instruction information adopts the first form and is "1", then PDCCH monitoring is skipped for the corresponding Cell, and the next PDCCH monitoring opportunity is pre-configured by high-level signaling.

[0239] 2) If the PDCCH monitor...

Abstract

The invention discloses a method, a device and equipment for monitoring a physical downlink control channel. The method comprises the following steps of: receiving a power-saving signaling which is sent by the network equipment and carries PDCCH monitoring indication information and / or monitoring cell indication information, wherein the PDCCH monitoring indication information is used for indicating whether to skip first PDCCH monitoring or not, the first PDCCH monitoring is periodic PDCCH monitoring in a search space configured by the terminal, and the monitoring cell indication information isused for indicating a cell needing to execute PDCCH monitoring; and performing PDCCH monitoring according to the PDCCH monitoring indication information and / or the power-saving signaling for monitoring the cell indication information in the power-saving signaling. According to the embodiment of the invention, the flexible PDCCH monitoring of one or more cells can be realized, and in addition, themonitoring power consumption of the equipment can also be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a monitoring method, device and equipment for a physical downlink control channel. Background technique [0002] In the New Radio (NR, New Radio, also known as 5G) system, in order to obtain downlink data, the terminal device needs to monitor the Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) to determine whether there is downlink scheduling information. The process of monitoring the PDCCH is: the terminal device decodes the PDCCH, and then checks through the cyclic redundancy check (CRC, Cyclic Redundancy Check) to determine whether it is the downlink control information (DCI, Downlink Control Information) carrying the scheduling information of the terminal device. . [0003] In order to help understand the solutions of the embodiments of the present invention, the following briefly introduces related concepts that may be involved ...
