Abstract
Techniques for fast adaptation of PDCCH monitoring by a UE via L1 signaling in order to reduce power consumption by the UE are disclosed. A base station sends first configuration information to a user equipment (UE) via higher layer signaling (e.g. RRC) to configure downlink control channel monitoring by the UE. Thereafter, the base station may send downlink control information to the UE via L1 signaling to adapt the PDCCH monitoring by the 6 UE. The downlink control information may temporarily override or modify the parameters for PDCCH monitoring set by higher layers. The downlink control information may be send in an existing downlink control message or in a new downlink control message.

A method implemented by a user equipment (UE) in a serving cell of a wireless communication network, the method comprising:
- receiving first configuration information from a base station or network node for configuring downlink control channel monitoring by the UE;
- monitoring the downlink control channel in accordance with the first configuration information;
- and
- receiving downlink control information from the base station via layer1 signaling;
- and
- adapting the downlink control channel monitoring responsive to the downlink control information.
