Apparatuses, methods, and systems are disclosed for performing a listen-before-talk on beams and/or panels. One method (500) includes receiving (502), at a user equipment, at least one indication to use a set of beams, a set of panels, or a combination thereof. The method (500) includes performing (504) the listen-before-talk on at least one beam of the set of beams, at least one panel of the set of panels, or a combination thereof before beginning a downlink reception, an uplink transmission, or a combination thereof. The method (500) includes performing (506) the downlink reception, the uplink transmission, or the combination thereof in response to the listen-before-talk being successful on the at least one beam of the set of beams, the at least one panel of the set of panels, or the combination thereof.

The present disclosure relates to a transmission method and apparatus. The method may comprise: receiving at least one piece of downlink control information; determining, based on the downlink control information, a time resource of a to-be-sent hybrid automatic retransmission request-acknowledgement and/or a content of the hybrid automatic retransmission request-acknowledgement; and sending the hybrid automatic retransmission request-acknowledgement based on the determined time resource and/or the determined content.

Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a network node comprises determining configuration information for a contention free preamble in a random access occasion, based at least in part on mapping between synchronization signal and physical broadcast channel blocks and preambles for two-step random access in the random access occasion. The contention free preamble is applicable for the two-step random access. The method further comprises transmitting the configuration information to a terminal device. According to some embodiments of the present disclosure, an association between signaling transmissions in a two-step random access procedure can be configured flexibly and efficiently.

In a case of using a different frequency band that is different from a frequency band including one or a plurality of frequency ranges, a terminal applies initial access configurations including a format of an initial access signal, the format being different from that for the frequency band. The terminal transmits the initial access signal via an initial access channel set based on the applied initial access configurations.

A random access control method can be applied to electronic devices and include: determining, when a medium access control layer receives a beam failure instance indication sent by a physical layer, whether a count value of a beam failure indication counter is greater than or equal to a preset value; detecting, when the count value of the beam failure indication counter is greater than or equal to the preset value, whether the electronic device is currently performing a random access; triggering, when the electronic device is not currently performing the random access, a new random access. According to the embodiments of the present disclosure, the user device can be prevented from occupying resources for a contention free random access (CFRA) for a long time.

The present disclosure relates to method and apparatus for controlling a transmission of a response signal in a wireless communication system. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system, comprises receiving a signal for a paging from a network; and receiving downlink (DL) data related to the paging, wherein a transmission of at least one of a paging response for the paging or acknowledgment (ACK) information for the DL data is determined based on information included in the signal for the paging.

A terminal is disclosed including a receiver a receiver that receives a radio resource control (RRC) reconfiguration message including comprising information regarding reconfiguration with synchronization; and a processor that monitors a quasi co-location of a demodulation reference signal antenna port for a downlink control channel in a control resource set based on information regarding random access resources within the information regarding the reconfiguration with synchronization. In other aspects, a radio communication method, a base station, and a system are also disclosed.

A method and an apparatus for entering a connected state with a network for continuing transmission in a wireless communication system is provided. The method may include starting a Time Alignment Timer (TAT). The method may include leaving a connected state with a network. The method may include performing transmission with a configured grant, wherein the configured grant is received from the network, while in leaving the connected state. The method may include performing a random access (RA) to the network, after the TAT is expired.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may transmit, to a base station, a request to transmit uplink control information (UCI), for a first physical uplink control channel (PUCCH) group that includes a primary cell (PCell) and for a second PUCCH group that includes a PUCCH secondary cell (SCell), via the PUCCH SCell. The apparatus may receive, from the base station, an indication of whether the request is rejected or approved. Numerous other aspects are described.

An operation method of a first device may comprise: receiving, from a second device, first configuration information signaled for CLI-related procedures; receiving, from the second device, second configuration information signaled for operating a multiplexing operation of the first device; in response to recognizing, with respect to a first resource, a collision between first DL-UL configuration information indicated by the first configuration information and second DL-UL configuration information indicated by the second configuration information, comparing priorities of the first DL-UL configuration information and the second DL-UL configuration information; and determining a DL-UL configuration applied to the first resource based on the compared priorities.
