Abstract
The present invention provides a method for a terminal and a base station including multiple TRPs to transmit/receive signals, and a device therefor. More particularly, the present invention provides a method whereby, if one or more base stations are present, and multiple TRPs are present in each of the base stations, a TRP for signal transmission/reception by a terminal and a base station is selected by using an uplink signal transmitted by the terminal, and a signal is transmitted/received based on the TRP. The present invention also provides a device for the method.
Claims19
A method of transmitting and receiving a signal to and from a user equipment (UE) by a base station (BS) including a plurality of transmission and reception points (TRPs) in a wireless communication system, the method comprising:
- transmitting, to the UE, resource allocation information on an uplink signal for uplink channel quality measurement;
- receiving the uplink signal from the UE through each of the plurality of TRPs;
- measuring uplink channel quality for each of the TRPs using the received uplink signal;
- selecting a TRP to be used in transmitting and receiving the signal to and from the UE from among the plurality of TRPs based on the measured uplink channel quality;
- and
- transmitting, to the UE in a radio resource control (RRC) Inactive state, a TRP selection command including information on the selected TRP.
A method of transmitting and receiving a signal to and from a base station (BS) including a plurality of transmission and reception points (TRPs) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from the BS, resource allocation information on an uplink signal for uplink channel quality measurement;
- transmitting the uplink signal to the BS based on the resource allocation information;
- and
- attempting to receive, in a radio resource control (RRC) Inactive state, a TRP selection command including information on a TRP to be used in transmitting and receiving the signal to and from the BS.
A base station (BS) for transmitting and receiving a signal to and from a user equipment (UE) in a wireless communication system, wherein the BS includes a plurality of transmission and reception points (TRPs), the BS comprising:
- a transmitter configured to communicate with the UE through the plurality of TRPs;
- a receiver configured to communicate with the UE through the plurality of TRPs;
- and
- a processor,
- wherein the processor is configured to:
- control the transmitter to transmit, to the UE, resource allocation information on an uplink signal for uplink channel quality measurement;
- control the receiver to receive the uplink signal from the UE through each of the plurality of TRPs;
- measure uplink channel quality for each of the TRPs using the received uplink signal;
- select a TRP to be used in transmitting and receiving the signal to and from the UE from among the plurality of TRPs based on the measured uplink channel quality;
- and
- control the transmitter to transmit, to the UE in a radio resource control (RRC) Inactive state, a TRP selection command including information on the selected TRP.
