There is disclosed a method of operating a transmitting node in a millimeter-wave communication network. The method includes transmitting communication signaling in a transmission timing structure, the communication signaling including leading reference signaling in a leading time interval at the beginning of the transmission timing structure and including trailing reference signaling in a trailing time interval at the end of the timing structure. The leading reference signaling starts with a first reference signaling time-domain sequence, and the trailing reference signaling ending with the first reference time-domain signaling sequence. The disclosure also pertains to related devices and methods.

Disclosed is a bandwidth part (BWP) switching method, a terminal, and a storage medium. The method includes: receiving target downlink control information (DCI) from a network device; wherein the target DCI comprises a first BWP, and the target DCI is configured to trigger the terminal to perform a BWP switching; de-enabling a timer-based BWP switching function according to the target DCI; wherein the timer-based BWP switching function indicates triggering the terminal to perform the BWP switching in response to no data transmission existing between the terminal and the network device within a timer duration of a timer; and switching a current BWP to the first BWP.

A method of communicating between nodes on a plurality of channels within the unlicensed spectrum is disclosed where coordination of the acquiring of the different channels is provided so that a further channel is acquired prior to the occupancy time of the currently used channel expiring. The method involves determining at one node that a channel in the unlicensed band has been acquired for a predetermined occupancy time. Initiating a scan of at least one further channel within the unlicensed spectrum to determine if a further channel is available. Once a predetermined time has passed and within the predetermined occupancy time, acquiring the available channel by transmitting a signal on it.

A UE uses a first bandwidth part to simultaneously receive switching requests from a plurality of transmission/reception points in a first time slot, calculates a scheduling time offset value on the basis of a plurality of scheduling time offsets decoded from the switching requests, and does not perform wireless signal transmission in a duration of time after the end of the time of the first three symbols in the first time slot. The duration of time is determined by the scheduling time offset value.

Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.

Provided are methods and apparatuses for transmitting and receiving control signaling and for determining information. The method include determining second information according to first information, where the second information includes at least one of the following: the number N of bits used in first control signaling to notify a first transmission parameter, a correspondence mapping table between an index value referenced by the first transmission parameter in the first control signaling and the value of the first transmission parameter, the type of the first transmission parameter notified by a predetermined indication field in the first control signaling, or position information of the bits used in the first control signaling to notify the first transmission parameter; and where the first information includes a relationship between a transmission time interval between the first control signaling and a first signal and a predetermined threshold K, where N and K are non-negative integers; and transmitting the first control signaling.

Systems and methods are provided for duplicate message detection and removal. A method includes receiving a message tagged with a sequence number during one of a first timing window and a second timing window, wherein the first and second timing windows are consecutive recurring timing windows in a network. The method additionally includes sending a response to the message during one of the timing windows and marking the sequence number with the timing window of the response. The method further includes adding the marked sequence number to an exclusion list and after a next timing window expires, deleting the sequence number from the exclusion list.

A user equipment of a wireless communication system is disclosed. The user equipment includes a communication module, and a processor. The processor is configured to transmit a radio frame divided into a plurality of subframes through the communication module, and perform a UL transmission in a partial subframe having a duration shorter than one subframe duration to the base station based on at least one of an indication of a base station and a result of a channel access of the wireless communication system.

Aspects of the present disclosure relate to a technique for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). A user equipment (UE) may receive and/or detect a downlink control information (DCI) that schedules at least one dynamic CORESET and indicates a TCI state from a list of one or more TCI states for the dynamic CORESET. The UE may apply the indicated TCI state for processing physical downlink control channel (PDCCH) transmissions in the dynamic CORESET when one or more conditions are met.

An information transmission method includes: receiving, by a terminal, a first downlink control information (DCI) used for scheduling the terminal to transmit uplink data through a physical uplink shared channel (PUSCH) in a target time unit; receiving, by the terminal, a second DCI, feedback response information of the second DCI being transmitted in the target time unit, and a time interval between a transmission time of the second DCI and a starting position of the PUSCH being not less than a preset time interval; determining a number of encoded bits of the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI; and transmitting, by the terminal according to the number of encoded bits, the uplink data and the feedback response information of the second DCI through the PUSCH in the target time unit.
