摘要： A method for enhancing communication interruption using supplementary uplink (SUL) in a wireless communication system includes: registering a user terminal at a cell using a normal uplink (NUL) carrier; receiving configuration information of a SUL carrier from the cell; identifying whether uplink configuration information on the NUL carrier is not received for a specified period of time; based on the uplink configuration information on the NUL carrier not being received for the specified period of time, setting the SUL carrier to be used as an uplink carrier; and performing a random access channel (RACH) procedure using the SUL carrier.

摘要： A communication control method is used in a user equipment that performs a predetermined data transmission in which uplink user data is transmitted during a random access procedure. The method comprises receiving, by the user equipment from a network node, a message including information related to the predetermined data transmission, the message being a message for transitioning the user equipment from an RRC connected state to a predetermined RRC state; transitioning, by the user equipment, from the RRC connected state to the predetermined RRC state in response to receiving the message; and determining, by the user equipment, whether to perform the predetermined data transmission based on the information included in the message. The predetermined RRC state is a state in which an RRC connection is released or suspended.

摘要： Methods for resource efficient data transmission are described herein. A method may comprise operating in one of an idle or an inactive mode and transmitting, in response to a random access (RA) message or a configured grant (CG), a small data transmission over an uplink channel. The RA message may be received in a two-step RA procedure or a four-step RA procedure. The method may further comprise transitioning from the idle or the inactive mode to a connected mode. The method may further comprise determining resources for transmitting the small data transmission. The method may comprise determining whether the small data transmission was successfully received and retransmitting, on a condition the small data transmission was not received, the small data transmission. The method may further comprise segmenting a small data packet into a plurality of small data packets and transmitting the small data packets in a plurality of transmission opportunities.

摘要： A method and a device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present disclosure, comprise transmitting a PRACH, and receiving an RAR on the basis of the PRACH. The PRACH is transmitted within one or two PRACH slots. The one or two PRACH slots are determined from among N number of slots corresponding to reference slots. 60 kHz SCS can be applied to the reference slots on the basis of the application of one from among 480 kHz SCS and 960 kHz SCS to the N number of slots.

摘要： A base station distributed unit may transmit a timing advance command for a timing advance group to a wireless device. The base station distributed unit may start a time alignment timer for the timing advance group of the wireless device in response to the transmission of the timing advance command. The base station distributed unit may determine expiration of the time alignment timer. The base station distributed unit may transmit a first message to a base station central unit. The first message may indicate the expiration of the time alignment timer for the timing advance group of the wireless device.

摘要： This application relates to communication methods and communication apparatuses. In an example method, a terminal device or a chip in the terminal device obtains first information. The first information is used to determine an access range corresponding to a first signal. In response to determining that the terminal device is located in the access range after a first moment, the terminal device or the chip in the terminal device sends a first random access preamble. The first random access preamble is associated with the first signal.

摘要： An information transmission method for a random access process includes: obtaining a preset mapping relationship between a physical uplink shared channel resource and a physical random access channel resource; and sending a random access message on a random access resource according to the preset mapping relationship. The random access resource comprises the PUSCH resource and the PRACH resource. When a random access channel occasion corresponding to the PRACH resource is not associated with an SSB, the RO is not associated with the PUSCH resource.
