Method for transmitting and receiving physical uplink control channel in wireless communication system, and device for supporting same
Disclosed are a method for transmitting and receiving a physical uplink control channel (PUCCH) between a terminal and a base station, and a device for supporting same. More specifically, disclosed are: a method for transmitting and receiving a PUCCH between a terminal and a base station through one or more resource elements included in one or more interlaces among interlaces of RB units in a frequency domain during one or two symbol periods unlike in a conventional method; and devices for supporting the same.
1. A method for transmitting a physical uplink control channel (PUCCH) by a user equipment (UE) in a wireless communication system, the method comprising:
determining one or more resource elements (REs) included in one or more interlaces as a PUCCH resource for transmitting the PUCCH, wherein the one or more interlaces are configured with resource blocks (RBs) apart from each other by a same spacing in a frequency domain in one or two symbols; and
transmitting, to a base station (BS), the PUCCH in the PUCCH resource,
wherein, when the PUCCH resource is configured with one symbol, the one or more REs are included in one interlace configured with RBs apart from each other by 10 RBs in the one symbol, and the one or more REs are configured with comb-type REs apart from each other by a same spacing among total REs of the one interlace.
2. The method according to claim 1 , wherein when the one or more REs are configured with the comb-type REs, REs except for the comb-type REs among the total REs include a sound reference signal (SRS) RE carrying an SRS.
3. The method according to claim 1 , wherein the one or more REs include one or more data REs carrying PUCCH data, and one or more reference signal (RS) REs carrying an RS.
4. The method according to claim 3 , wherein a ratio between the data REs and the RS REs is equal in each RB included in the one interlace.
5. The method according to claim 1 , wherein when the PUCCH resource is configured with two symbols, the one or more REs are included in one interlace configured independently for each of the two symbols.
6. The method according to claim 1 , wherein when the PUCCH resource is configured with two symbols, the one or more REs are included in one interlace configured with RBs apart from each other by 10 RBs in the two symbols, and an RB including the one or more REs is different in each of the two symbols.
7. The method according to claim 1 , wherein when the PUCCH resource is configured with two symbols, the one or more REs are included in one interlace configured with RBs apart from each other by 10 RBs in the two symbols, and
wherein the transmitting the PUCCH includes transmitting the PUCCH by applying an orthogonal cover code (OCC) on each of the two symbols.
8. The method according to claim 1 , further comprising:
receiving information indicating the PUCCH resource from the BS.
9. A communication device for transmitting a physical uplink control channel (PUCCH) in a wireless communication system, the communication device comprising:
a memory; and
a processor operably coupled with the memory and configured to:
determine one or more resource elements (REs) included in one or more interlaces as a PUCCH resource for transmitting the PUCCH, wherein the one or more interlaces are configured with resource blocks (RBs) apart from each other by a same spacing in a frequency domain in one or two symbols; and
transmit, to a base station (BS), the PUCCH in the PUCCH resource,
wherein, when the PUCCH resource is configured with one symbol, the one or more REs are included in one interlace configured with RBs apart from each other by 10 RBs in the one symbol, and the one or more REs are configured with comb-type REs apart from each other by a same spacing among total REs of the one interlace.
10. A communication device for receiving a physical uplink control channel (PUCCH) in a wireless communication system, the communication device comprising:
a memory; and
a processor operably coupled with the memory and configured to:
transmit, to a user equipment (UE), information indicating a PUCCH resource; and
receive, from the UE, the PUCCH in the PUCCH resource,
wherein the PUCCH resource includes one or more resource elements (REs) included in one or more interlaces configured with resource blocks (RBs) apart from each other by a same spacing in a frequency domain in one or two symbols, and
wherein, when the PUCCH resource is configured with one symbol, the one or more REs are included in one interlace configured with RBs apart from each other by 10 RBs in the one symbol, and the one or more REs are configured with comb-type REs apart from each other by a same spacing among total REs of the one interlace.
