摘要

Disclosed are a method and a device for transmitting or receiving downlink control information in a wireless communication system. A method for receiving downlink control information (DCI) according to an embodiment of the present disclosure any comprise the steps of: repeatedly receiving the DCI via a plurality of physical downlink control channel (PDCCH) candidates; and transmitting or receiving data scheduled via the DCI. The DCI may be transmitted via a first physical downlink control channel (PDCCH) candidate within a first search space set and a second PDCCH candidate within a second search space set, the first search space set and the second search space set may be related to different transmission configuration indication (TCI) states, and a window that is a duration in which the first PDCCH candidate and the second PDCCH candidate are transmitted may be preconfigured in a time domain.

說(shuō)明書

Here, the UE may report the maximum number of CORESETs that the UE can be configured in one BWP and one serving cell as a capability to the network.

In particular, as in embodiment 5 above, the network can configure one or more CORESETs to the UE within the maximum number of CORESETs reported by the UE by differently counting the number of CORESETs based on the number of TCI states configured in CORESET.

Here, the UE may report the maximum number (y) of COREST in which two TCI states are configured and the maximum number (x) of COREST in which one TCI state is configured as a capability separately to the network. And/or the UE may report the maximum value z of the sum of the number of CORESTs in which two TCI states are configured and the number of CORESTs in which one TCI state is configured as a capability to the network.

The operation that a UE (100/200 in FIG. 20) transmits capability information of the UE to a network (200/100 in FIG. 20) of the step S1801 described above may be implemented by an apparatus of FIG. 20 to be described below. For example, referring to FIG. 20, one or more processors 102/202 may control one or more transceivers 106 and/or one or more memories 104 to transmit capability information of a UE, and one or more transceivers 106 may transmit capability information of a UE to a network.

A UE may receive configuration information for multiple TRP-based transmission/reception through/using TRP 1 (and/or TRP 2) from a network side (S1802).
