Abstract
According to one embodiment of the present invention, a method of decoding, by a user equipment, a downlink signal in a wireless communication system comprises the steps of: receiving rate matching pattern information indicating a rate matching resource having a repetition period from a base station; and decoding a downlink shared channel using the rate matching pattern information.
Claims15
A method for receiving a physical downlink shared channel (PDSCH) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station (BS), resource configuration information on resources not to be used for a PDSCH;
- and
- receiving, from the BS, the PDSCH based on the resource configuration information,
- wherein the resource configuration information includes a first bitmap, a second bitmap and, time unit pattern based on a period,
- wherein the first bitmap represents configuration of frequency region for the resources not to be used for the PDSCH and the second bitmap represents configuration of time region for the resources not to be used for the PDSCH, and
- wherein the time unit pattern represents one or more time units for the resources not to be used for the PDSCH, among a plurality of time units in the period, the one or more time units are a time unit in which resource configuration represented by the first and the second bitmap is used.
