The present specification provides a method for receiving data on the basis of quasi co-location (QCL) in a wireless communication system. More particularly, a data reception method performed by means of a terminal comprises the steps of: receiving transmission configuration indication (TCI) state information relating to at least one QCL indication with respect to a downlink reference signal (DL RS) from a base station by means of RRC signaling; receiving a physical downlink control channel (PDCCH), comprising downlink control information (DCI), on a first slot from the base station; and receiving a physical downlink shared channel (PDSCH) comprising data from the base station on the basis of one or more QCL indications. Therefore, the flexibility of the terminal during beam switching can be enhanced.

In 5G/6G wireless networks, user devices and base stations may adjust their transmission power according to the distance to the recipient, and thereby provide sufficient reception without wasting energy or generating interference. User devices can determine their own location by GPS, for example, and transmit that data to the base station so that the base station can adjust its downlink power accordingly. Likewise. base stations can transmit their location coordinates to user devices in, for example, a system information message. Sidelink, or V2V and V2X, messages can likewise be power-adjusted after user devices exchange their location coordinates. Mobile user devices can also indicate their speed and direction of travel, so that the base station or other user devices can calculate the changing distance and compensate power accordingly. The method may enhance reliability by providing that messages arrive at the recipient with sufficient amplitude for reception, and may provide low latency by avoiding the time-consuming power scan, while avoiding delays for retransmissions and the like.

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for transmission configuration indication states that indicate quasi-collocation relationships. For example, a user equipment (UE) may transmit an uplink reference signal to a base station and receive, in response, a transmission configuration indication state from the base station that is based on the uplink reference signal. In some examples, the transmission configuration indication state may indicate a quasi-collocation relationship between the uplink reference signal and one or more reference signals associated with a downlink channel. In some implementations, the quasi-collocation relationship may be a spatial relationship between one or more antenna ports associated with the base station used to receive the uplink reference signal and one or more antenna ports used to transmit downlink data. The UE may receive downlink data based on the transmission configuration indication state and the indicated quasi-collocation relationship.
