Abstract

The embodiment of the invention provides a method for monitoring a physical downlink control channel, user equipment and network side equipment. The method comprises the following steps: acquiring oneor more bits in DCI of a first PDCCH monitored by UE, wherein the one or more bits in the DCI of the first PDCCH indicate an unmonitored PDCCH and / or a monitored PDCCH; and determining an unmonitored PDCCH and / or a monitored PDCCH according to one or more bits of the DCI of the first PDCCH. In this way, the UE is prevented from monitoring unnecessary PDCCH, and the power consumption of the UE can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method for monitoring a Physical Downlink Control Channel (PDCCH), user equipment, and network side equipment. Background technique [0002] At present, in the new radio (New Radio, NR) technology of the long-term evolution (Long Term Evolution, LTE) and the fifth-generation mobile communication (fifth-generation, 5G), the user equipment (User Equipment, UE) is usually in each sub- PDCCH blind detection is performed on a frame or a time slot (slot). If the UE receives the PDCCH belonging to the UE, then the UE receives downlink data or sends uplink data on the time-frequency resource indicated by the PDCCH. If the UE does not receive the PDCCH belonging to the UE, the UE continues to perform PDCCH blind detection on the next subframe or slot or on a subframe or slot that conforms to the PDCCH monitoring period and offset configured by the bas...
