Method for transmitting and receiving multiplexed uplink control channel and localized sounding reference symbol and device therefor
A method for transmitting a multiplexed uplink control channel and localized sounding reference symbol (localized SRS) by a terminal comprises a step of dividing the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain and then transmitting the divided uplink control channel, when a frequency bandwidth of the localized SRS is smaller than or equal to a coherent bandwidth, wherein the divided uplink control channel sub-blocks may be frequency-division-multiplexed together with at least one localized SRS and then transmitted in one symbol.
1. A method performed by a user equipment (UE) operating in a wireless communication system, the method comprising:
multiplexing sounding reference signals (SRSs) and uplink control channel sub-blocks segmented from an uplink control channel in a frequency domain; and
transmitting a symbol including the SRSs and the uplink control channel sub-blocks that are multiplexed, wherein the uplink control channel includes uplink control information, and
wherein the multiplexed uplink control channel sub-blocks are transmitted without demodulation reference signals.
2. The method of claim 1 , wherein the uplink control channel sub-blocks and the SRSs are transmitted on a same antenna port.
3. The method of claim 1 , wherein at least one of the SRSs is transmitted at a resource between the segmented uplink control channel sub-blocks.
4. The method of claim 1 , wherein the uplink control channel is segmented into the uplink control channel sub-blocks and transmitted, based on the uplink control channel being used for a specific service.
5. The method of claim 1 , wherein a region except a resource region related to a reference signal included in the uplink control channel is segmented into the uplink control channel sub-blocks.
6. A method performed by a base station (BS) operating in a wireless communication system, the method comprising:
receiving a symbol including sounding reference signals (SRSs) and uplink control channel sub-blocks that are multiplexed in a frequency domain,
wherein the uplink control channel sub-blocks are segmented from an uplink control channel,
wherein the uplink control channel includes uplink control information, and
wherein the multiplexed uplink control channel sub-blocks are received without demodulation reference signals.
7. The method of claim 6 , wherein at least one of the SRSs is received at a resource between the segmented uplink control channel sub-blocks.
8. The method of claim 6 , further comprising:
estimating an uplink channel based on the SRSs.
9. The method of claim 6 , wherein a region except a resource region related to a reference signal included in the uplink control channel is segmented into the uplink control channel sub-blocks.
10. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a transceiver; and
a processor coupled to the transceiver, wherein the processor is configured to:
multiplex sounding reference signals (SRSs) and uplink control channel sub-blocks segmented from an uplink control channel in a frequency domain; and
transmit a symbol including the SRSs and the uplink control channel sub-blocks that are multiplexed,
wherein the uplink control channel includes uplink control information, and
wherein the multiplexed uplink control channel sub-blocks are transmitted without demodulation reference signals.
11. The UE of claim 10 , wherein the processor is further configured to transmit the segmented uplink control channel sub-blocks and the SRSs on a same antenna port.
12. The UE of claim 10 , wherein the processor is further configured to transmit at least one of the SRSs at a resource between the segmented uplink control channel sub-blocks.
13. The UE of claim 10 , wherein the processor is further configured to transmit the segmented uplink control channel sub-blocks in a region of the uplink control channel except a resource region related to a reference signal included in the uplink control channel.
14. A base station (BS) configured to operate in a wireless communication system, the base station comprising:
a transceiver; and
a processor coupled to the transceiver,
wherein the processor is configured to:
receive a symbol including sounding reference signals (SRSs) and uplink control channel sub-blocks that are multiplexed in a frequency domain,
wherein the uplink control channel sub-blocks are segmented from an uplink control channel,
wherein the uplink control channel includes uplink control information, and
wherein the multiplexed uplink control channel sub-blocks are received without demodulation reference signals.
15. The base station of claim 14 , wherein the processor is configured to estimate an uplink channel based on the SRSs.
16. The method of claim 1 , wherein the SRSs include a first SRS and a second SRS, and
wherein a frequency bandwidth of the first SRS is equal to or smaller than a length of a coherent bandwidth.
17. The method of claim 1 , wherein the SRSs include a first SRS and a second SRS, and
wherein at least one of the uplink control channel sub-blocks is located between the first SRS and the second SRS.
