Methods and apparatuses for signal transmission and reception are provided for a wireless communication system. Information for configuring a plurality of physical uplink control channel (PUCCH) resources is transmitted to a terminal. Downlink control information (DCI) is transmitted to the terminal on a physical downlink control channel (PDCCH). The DCI includes a resource indicator for indicating a PUCCH resource among the plurality of PUCCH resources. Uplink control information (UCI) is received from the terminal on the PUCCH resource indicated by the resource indicator.

A downlink reception triggering method, a terminal, and a network-side device are provided. A method on a terminal side includes transmitting a first uplink signal, where the first uplink signal is used to trigger a first downlink reception.

A terminal according to one embodiment of the present invention determines and reports a specific codebook-based HARQ-ACK on the basis of the result of receiving a plurality of PDSCHs, and, on the basis of a first-type codebook-based HARQ-ACK having been set for scheduling of the plurality of PDSCHs, the terminal can perform first start symbol and length indicator value (SLIV) pruning on the basis of a set of the SLIVs of PDSCHs, which can be potentially scheduled on each slot of a bundling window determined on the basis of a plurality of candidate PDSCH-to-HARQ feedback timing values, and perform second SLIV pruning on the basis of a set of the SLIVs of PDSCHs, which can be potentially scheduled even on at least one slot that does not belong to the bundling window.

The present disclosure provides a method and device in a node for wireless communications. A first node determines a first resource set and a first resource set group out of M resource sets; monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapped in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is connected to one or two spatial states; a reference resource set is any of the M resource sets different from the first resource set; whether the reference resource set satisfies a first condition is used to determine whether the reference resource set belongs to the first resource set group. The above method avoids the performance loss incurred by UE's unnecessary dropping the monitoring on some PDCCH candidates.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining application timing for path loss reference signals (PL RS). For example, the application timing is determined by determining an applicable time for a medium access control control element (MAC-CE) based PL RS for physical uplink control channel (PUCCH) and other uplink transmissions. A user equipment (UE) may receive a MAC-CE indicating a PL RS update and determine the applicable time for applying the PL RS update based on one or more conditions. The applicable time may be a period after acknowledgement of the MAC-CE or correspond to a certain measurement sample of a new PL RS a period after acknowledgement of the MAC-CE. The one or more conditions may relate to a total configured number of PL RS for the UE, whether a MAC-CE based PL RS activation feature is enabled, among others.

The present disclosure provides a method and a device in a UE and a base station for wireless communications. The UE receives first information, and transmits a first radio signal in a first time window in a first sub-band. The first information is used for determining the first time window; a time offset of a start time for a transmission of the first radio signal relative to a reference time belongs to a target offset set, the target offset set including W offset value(s); time offset(s) of W start time(s) respectively relative to the reference time is(are) respectively equal to the W offset value(s); any of the W start time(s) belongs to one of N time units, any of the N time units includes at least one of the W start times.

A method performed by a terminal in a wireless communication system includes: receiving, from a base station, configuration information associated with a channel state information (CSI) report including at least one information associated with a CSI resource setting; receiving, from the base station, information associated with channel occupancy duration; determining whether at least one symbol for receiving a channel state information reference signal (CSI-RS) is within channel occupancy duration, based on the at least one information associated with the CSI resource setting and the received information associated with the channel occupancy duration; receiving, from the base station, at least one CSI-RS on the at least one symbol, based on a result of the determining; and when the CSI report is determined to be transmitted, transmitting; to the base station, the CSI report based on the configuration information associated with the CSI report and the received at least one CSI-RS.

A method for performing an uplink transmission by a user equipment in a non-terrestrial network, a method for scheduling uplink transmission in a non-terrestrial network, a user equipment and a base station are provided. The method comprises: receiving, from a base station, a first information for indicating uplink transmission resources, and a second information, wherein the second information comprises a first parameter for indicating the uplink transmission resources; performing, based on the first information and the second information, an uplink transmission on the uplink transmission resources.

Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a control message in a first control channel occasion associated with a first quasi-colocation (QCL) property, the control message indicating a transmission of a data message within a threshold time period. The UE may receive, from the base station, an indication to skip monitoring of a second control channel occasion within the threshold time period and may receive the data message in accordance with a second QCL property, or drop reception of the data message, based on the indication. Additionally, or alternatively, the base station may transmit a message indicating a unified transmission configuration indicator (TCI) state associated with the second QCL property, and the UE may receive the data message in accordance with the second QCL property based on the unified TCI state.
