Abstract
Provided herein is a method and apparatus for configuring a physical uplink control channel (PUCCH) resource in a wireless communication system and, most particularly, in a new radio access (NR) technology. More specifically, when and/or for which operation the default PUCCH resource is being used may be defined. For example, a wireless device may receive information on a default physical uplink control channel (PUCCH) resource, and the wireless device may transmit uplink control information (UCI) to a gNB by using the default PUCCH resource, only before establishing a radio resource control (RRC) connection with the gNB.
Claims11
A method performed by a wireless device in a wireless communication system, comprising:
- transmitting first uplink control information (UCI) to a network using a default physical uplink control channel (PUCCH) resource before a radio resource control (RRC) connection for the wireless device is established;
- and
- transmitting second UCI to the network using a user equipment (UE)-dedicated PUCCH resource after the RRC connection for the wireless device is established,
- wherein the default PUCCH resource is unused after the RRC connection is established,
- wherein a transmission using the default PUCCH resource is based on a beam used for a physical uplink shared channel (PUSCH) transmission scheduled by a random access response in a random access procedure, and
- wherein a transmission using the UE-dedicated PUCCH resource is based on a beam that is explicitly indicated to the wireless device via a configuration by the network.
A wireless device in a wireless communication system, comprising:
- a memory;
- a transceiver;
- and
- at least one processor operatively connected to the memory and the transceiver,
- wherein the at least one processor is configured to:
- control the transceiver, to transmit first uplink control information (UCI) to a network using a default physical uplink control channel (PUCCH) resource before a radio resource control (RRC) connection for the wireless device is established;
- and
- control the transceiver to transmit second UCI to the network using a user equipment (UE)-dedicated PUCCH resource after the RRC connection for the wireless device is established,
- wherein the default PUCCH resource is unused after the RRC connection is established,
- wherein a transmission using the default PUCCH resource is based on a beam used for a physical uplink shared channel (PUSCH) transmission scheduled by a random access response in a random access procedure, and
- wherein a transmission using the UE-dedicated PUCCH resource is based on a beam that is explicitly indicated to the wireless device via a configuration by the network.
A processor for a wireless device in a wireless communication system, wherein the processor is configured to:
- control the wireless device so as to transmit first uplink control information (UCI) to a network using a default physical uplink control channel (PUCCH) resource before a radio resource control (RRC) connection for the wireless device is established;
- and
- control the wireless device so as to transmit second UCI to the network using a user equipment (UE)-dedicated PUCCH resource after the RRC connection for the wireless device is established,
- wherein the default PUCCH resource is unused after the RRC connection is established,
- wherein a transmission using the default PUCCH resource is based on a beam used for a physical uplink shared channel (PUSCH) transmission scheduled by a random access response in a random access procedure, and
- wherein a transmission using the UE-dedicated PUCCH resource is based on a beam that is explicitly indicated to the wireless device via a configuration by the network.
