The present invention relates to a method of performing a random access (RA) procedure by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: triggering the RA procedure, wherein, when there is an ongoing scheduling request (SR) procedure on a first uplink (UL) bandwidth part (BWP), a second UL BWP is selected, wherein both an SR resource and PRACH resources are configured in the second ULBWP; and transmitting a RA preamble and a SR of the ongoing SR procedure on the second ULBWP.

Method and apparatus for requesting uplink resource with bandwidth part switching in wireless communication system

A method and apparatus for dynamic configuration of a maximum number of sidelink retransmissions for a data unit in a wireless communication system is provided. A first wireless device in sidelink receives, from a network, information related to a first retransmission number for a first logical channel and a second retransmission number for a second logical channel. The first wireless device determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and performs sidelink transmission of the data unit to a second wireless device based on the retransmission number of the data unit.

Dynamic configuration of maximum number of sidelink retransmissions for data unit

A method for transmitting a scheduling request (SR) by a terminal in a wireless communication system according to one embodiment of the present specification comprises: a step for receiving setting information related to an SR; and a step for transmitting at least one SR on the basis of the setting information. On the basis of the at least one SR overlapping with a different type of uplink control information (UCI), a UCI bit in which a specific field related to the at least one SR and the different type of UCI are combined is transmitted. On the basis of the at least one SR being related to beam failure recovery (BFR), the specific field indicates the beam failure recovery.

Method and device for transmitting and receiving scheduling request in wireless communication system

In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a common control channel (CCCH) service data unit (SDU) on a physical uplink channel (PUSCH). The UE receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU may include a MAC PDU associated with a contention resolution identity (CRID) in the MAC PDU. The UE determines whether a MAC SDU is present or not in the MAC PDU, based on the MAC SDU indicator associated with a CRID in the MAC PDU in a state in which the CRID matches the CCCH SDU.

Method of performing random access (RA) procedure, and transmitting device, apparatus and storage medium therefor, and method and apparatus for transmitting mac PDU of RA procedure

The present invention relates to a method of performing measurement by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: when an uplink data transmission occurs in a measurement gap, determining a starting point of a temporary measurement gap based on a completion time of the uplink data transmission; transmitting information about the temporary measurement gap including the starting point of the temporary measurement gap; transmitting an uplink data during the measurement gap; and performing measurements during the temporary measurement gap.

Method and apparatus for performing measurement by user equipment in wireless communication system

In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a control channel (CCCH) service data unit (SDU) on a physical uplink shared channel (PUSCH); and receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU includes a MAC subheader. The MAC subheader includes a first indicator field regarding whether the MAC subheader include an RAP identity (ID) or not. The MAC subheader further includes a second indicator field regarding whether the MAC subheader includes a backoff indicator field or not, based on the first indicator field set to a value indicating that the MAC subheader does not include an RAP ID.

Method of performing random access (RA) procedure, and transmitting device, apparatus and storage medium therefor, and method and apparatus for transmitting MAC PDU of RA procedure

The present invention relates to a method of performing a random access to a base station by a user equipment (UE) in a wireless communication system. In particular, the method includes transmitting a random access preamble and a payload including a common control channel (CCCH) service data unit (SDU) to the network; and receiving a medium access control (MAC) protocol data unit (PDU) in response to the random access preamble and the payload, wherein the MAC PDU includes a contention resolution identifier (CRID) and an indicator indicating a presence of a signaling radio bearer (SRB) radio resource control (RRC) message corresponding to the CRID in the MAC PDU.

A method and apparatus for reconstruction of a protocol data unit (PDU) for fast and reliable retransmission of a service data unit (SDU) after maximum retransmission is provided. Upon determining that a hybrid automatic repeat request (HARQ) retransmission of a first PDU including a specific SDU is unsuccessful, a wireless device constructs a second PDU including the first SDU which is prioritized to be included in the second PDU.

Reconstruction of data unit

A method and apparatus for determination of a maximum number of uplink retransmissions in a wireless communication system is provided. A wireless device receives, from a network, information related to a first retransmission number for a first logical channel and second retransmission number for a second logical channel, determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and transmits, to the network, information for the retransmission number of the data unit.

Determination of maximum number of uplink retransmissions

In the present disclosure, a transmitting device transmits a first message comprising i) a first random access preamble with a first random access preamble identifier (RAPID) and ii) a first uplink payload; receives a random access response (RAR) medium access control (MAC) protocol data unit (PDU) including i) a first field set to represent presence of one or more RAPIDs and ii) the one or more RAPIDs; determines whether both of the first RAP and the first payload is successfully transmitted, based on whether the one or more RAPIDs include the first RAPID; and monitors a second message related to the first message based on determining that both of the first RAP and the first payload is successfully transmitted.

Method of performing random access procedure, and transmitting device, apparatus and storage medium therefor

According to one embodiment of the present application, a method for transmitting a physical uplink control channel (PUCCH) by a terminal in a wireless communication system comprises a step of receiving setting information associated with a PUCCH, and a step of transmitting the PUCCH on the basis of the setting information. The PUCCH is transmitted from a specific PUCCH resource selected from among overlapped PUCCH resources. The specific PUCCH resource is characterized by being associated with beam failure recovery (BFR).
