Methods and apparatuses for associating aperiodic SRS triggering state(s) with SRS resource sets or SRS CC sets are disclosed. A method comprises transmitting an Activation/Deactivation MAC CE to indicate or update the association between aperiodic SRS triggering state(s) and the aperiodic SRS resource set(s) for the SRS request field value carried by DCI format 0_1 or 1_1 or DCI format 2_3 with a higher layer parameter srs-TPC-PDCCH-Group=typeB or the SRS CC set(s) for the SRS request field value carried by DCI format 2_3 with the higher layer parameter srs-TPC-PDCCH-Group=typeA.

Provided are a method, device and storage medium for configuring a starting symbol position of an uplink data channel. The method includes: determining a configuration value of a first type parameter set, where the first type parameter set is a set of uplink data parameters; determining a configuration range of a starting symbol position of an uplink data channel according to the configuration value of the first type parameter set; and selecting a starting symbol position of the uplink data channel from the configuration range of the starting symbol position of the uplink data channel, and notifying a receiving end of the selected starting symbol position of the uplink data channel.

The present specification relates to a method for receiving dormant bandwidth part (BWP) configuration information, performed by a terminal in a wireless communication system, the method comprising: receiving the dormant BWP configuration information from a base station, wherein the dormant BWP configuration information is information about a downlink BWP used as the dormant BWP among at least one downlink BWP set to the terminal; receiving, from the base station, downlink control information (DCI) notifying activation of the dormant BWP; and stopping monitoring of a physical downlink control channel (PDCCH) on the dormant BWP, wherein a BWP inactivity timer is not used on the basis of the activation of the dormant BWP, and the BWP inactivity timer is a timer for a transition to a default BWP.

This application discloses a downlink data sending method, a downlink data receiving method, and an apparatus, and relates to the communication field, to resolve a problem that feedback information fails to be sent, and consequently, a retransmission probability of downlink data is increased, and data transmission efficiency is reduced. When at least two of P PDSCHs in one slot overlap in time domain, a network device cancels sending of partially overlapping PDSCHs. If one first PDSCH whose sending is canceled is the last repetition in PDSCH repetitions of first data, and a terminal device receives another repetition in the PDSCH repetitions of the first data before the first PDSCH, the terminal device still sends feedback information for the first data to the network device in a feedback slot corresponding to the first PDSCH.

This disclosure provides methods, devices, and systems supporting power control parameter configuration for configured grants (CGs). In some implementations, a user equipment (UE) may receive control signaling configuring multiple sounding reference signal (SRS) resource sets and multiple sets of power control parameters for CG uplink transmission. The UE may receive downlink control information (DCI) scheduling a retransmission and indicating which set of power control parameters the UE is to use for the CG uplink retransmission. In some other implementations, the control signaling may configure multiple SRS resources sets but a single set of power control parameters. The UE may receive DCI activating the CG configuration or scheduling a retransmission, the DCI indicating a second set of power control parameters not configured by the control signaling. The UE may automatically use the power control parameters configured by the control signaling or may determine a second set based on the DCI.

A method for transmitting information, includes: transmitting on one carrier wave according to at least one of a preset transmission mode and a transmission mode indicated by a base station eNB when agreed transmission time of two or more physical uplink shared channels PUSCH overlaps.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for de-configuring a cell from PUCCH resource in a carrier aggregation system, the method comprising: configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; receiving an RRC signaling indicating that the PUCCH resource PUCCH resource is de-configured from the SCell; and de-activating the SCell after the UE de-configures the PUCCH resource from the SCell according to the RRC signaling.

The present disclosure relates to a network node having a processor and a transceiver. The processor is configured to select at least one user device if a Channel Estimation Timer (CET) for a radio channel between the network node and the at least one user device is valid, and to schedule data transmission to the at least one selected user device. The transceiver is configured to perform the scheduled data transmission to the at least one selected user device. The present disclosure also describes a corresponding method, a wireless communication system including such a network node, a computer program, and a computer program product.

Wireless communications are described. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal or the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal or the second signal. Adjusting and/or dropping at least one of the first signal or the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for terminating HARQ retransmissions. A wireless receiver may determine that a transmission of a first TB based on a first redundancy version is not received from a wireless transmitter. Based on the determination, the wireless receiver may transmit, to the wireless transmitter, a HARQ ACK to terminate one or more HARQ retransmissions associated with the different redundancy versions of the first TB.
