Embodiments of the present application are directed to a method and apparatus for channel access. A method according to an embodiment of the present application may include: receiving control information associated with a channel occupancy (CO) initiated by a base station, determining whether the CO can be shared for a physical uplink shared channel (PUSCH) transmission and an uplink transmission beam associated with the CO in the case of being shared based on the control information, and transmitting the PUSCH transmission with the determined uplink transmission beam in the case that the CO can be shared.

Method and apparatus for channel access

The present application is related to a method and apparatus for semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook determination for FBE operation under 3GPP 5G new radio (NR). A method for wireless communications performed by a UE includes: receiving downlink control information (DCI) for scheduling a data transmission in a current periodic channel occupancy; determining whether there is HARQ-ACK feedback corresponding to a data transmission postponed in an earlier periodic channel occupancy; and transmitting a HARQ-ACK codebook in the current periodic channel occupancy, wherein, in response to determining that there is the HARQ-ACK feedback corresponding to the data transmission postponed in the earlier periodic channel occupancy, the HARQ-ACK codebook comprises HARQ-ACK feedback corresponding to the data transmission in the current periodic channel occupancy and the postponed HARQ-ACK feedback corresponding to the data transmission in the earlier periodic channel occupancy.

Method and apparatus for HARQ-ACK codebook determination for frame-based equipment operation

Embodiments of the present disclosure relate to methods and apparatuses. According to some embodiments of the disclosure, a method may include: determining a first redundancy version (RV) pattern from a set of RV patterns for transmitting a number of repetitions of a first transport block (TB) in a first configured grant (CG) period; performing a channel access procedure for a first repetition of the first TB according to the first RV pattern; and transmitting the number of repetitions of the first TB according to the first RV pattern in response to the channel access procedure for the first repetition of the first TB being successful.

Method and apparatus for uplink transmission on configured grant resources

The present application relates to a method and apparatus for downlink data reception. one embodiment of the subject application provides a method, comprising: determining one or more control resource sets from a plurality of control resource sets in response to first Downlink Control Information (DCI) being received in at least one of the one or more control resource sets; and detecting second DCI only in the determined one or more control resource sets within a time duration.

Method and apparatus for downlink data reception

The subject disclosure relates to a method and apparatus for reducing a one-shot HARQ-ACK codebook size. One embodiment of the subject disclosure provides a method performed by a User Equipment (UE), including receiving, from a base station (BS), a first signaling configuring a first plurality of carriers, wherein HARQ-ACK feedback for the first plurality of carriers is transmitted in same PUCCH; receiving, from the BS, Downlink Control Information (DCI) requesting HARQ-ACK feedback for one or more carriers of the first plurality of carriers; and transmitting, to the BS, a HARQ-ACK codebook in the PUCCH, wherein the HARQ-ACK codebook comprises the HARQ-ACK feedback for the one or more carriers of the first plurality of carriers.

Method and apparatus for reducing one-shot hybrid automatic repeat request-acknowledgement (HARQ-ACK) codebook size

The subject disclosure relates to a method and apparatus for determining an enhanced dynamic HARQ-ACK codebook. One embodiment of the subject disclosure provides a method including: receiving first Downlink Control Information (DCI) scheduling a first Physical Downlink Shared Channel (PDSCH); determining an index of a first PDSCH group and whether new Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) feedback is requested for the first PDSCH group, wherein the first PDSCH group includes at least the first PDSCH; and transmitting a first HARQ-ACK codebook for the first PDSCH group, wherein the first HARQ-ACK codebook comprises HARQ-ACK feedback for each PDSCH of the first PDSCH group.
