A terminal device receives first scheduling information from an access network device, where the first scheduling information is used to schedule the terminal device to transmit a first transport block by using an unlicensed carrier; performs rate matching on the first transport block, to obtain uplink data; detects the unlicensed carrier, and determines a start time domain symbol, used to send the uplink data, in at least two time domain symbols included in a first subframe, where the at least two time domain symbols include a first time domain symbol and a second time domain symbol, the second time domain symbol is later than the first time domain symbol, and the start time domain symbol is the first time domain symbol or the second time domain symbol; and sends the uplink data to the access network device from the start time domain symbol.

Disclosed in the present application are a uplink control channel transmission method and device, for solving the problems, in the prior art, that no relevant solution for defining the transmission structure of a long NR-PUCCH with different lengths in consideration with whether the intra-slot frequency hopping is supported is available yet. The method includes: determining a transmission length or format of a uplink control channel (PUCCH) in a slot; determining a transmission structure of the PUCCH on the basis of the transmission length or format; and transmitting the PUCCH in the slot according to the transmission structure.

Various communication systems may benefit from efficient communications. For example, low latency long term evolution (LTE) systems may benefit from a short physical uplink shared channel (PUSCH) arrangement. A method may include operating a user equipment to follow a shortened transmission time interval. The shortened transmission time interval can be an integer number, L, of symbols in length. The method can also include sending a demodulation reference signal in at least a first symbol of the L symbols of the shortened transmission time interval.

An information transmission method includes: sending target information on at least one sub symbol of a first OFDM symbol. The first OFDM symbol includes at least two sub symbols.

The present disclosure relates to an electronic device, a wireless communication method, and a computer-readable medium. The electronic device for wireless communication according to one embodiment comprises a processing circuit. The processing circuit is configured to obtain a set of collaborative devices of a target device, the set of collaborative devices comprising one or more collaborative devices. The processing circuit is further configured to control to send data for the target device to the target device and at least one collaborative device so that the at least one collaborative device forwards the data to the target device.

The disclosure relates to a communication technique that converges a 5.sup.th generation (5G) communication system for supporting a higher data rate after a 4.sup.th generation (4G) system with IoT technology, and a system thereof. The disclosure may be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail, security and safety related services, or the like) based on 5G communication technology and Internet of things (IoT)-related technology. A method for transmitting an uplink channel by a base station or a user equipment (UE) in a wireless communication system is provided.

Embodiments of the present disclosure provide a data transmission method and a network device. The method includes generating, by a network device, a slot format indicator (SFI). The SFI is used to indicate one or more slot format indices. The one or more slot format indices are used to determine a slot format in a time unit based on a first correspondence relationship. The first correspondence relationship is a relationship between a slot format index and a slot format. The method also includes sending, by the network device, the SFI to a terminal device. The method further includes sending, by the network device, a physical downlink control channel (PDCCH) to the terminal device according to the slot format corresponding to the one of the one or more slot format indices indicated by the SFI. The SFI is carried in downlink control message (DCI), and the DCI is scrambled by using a radio network temporary identifier (RNTI).

In the transmission of a narrowband positioning reference signal (NPRS), by a base station, in a cellular mobile communication system supporting narrowband-Internet of Things (NB-IoT), the base station transmits an NPRS by using a predetermined part of a sequence defined by a generation formula, which is the same as a positioning reference signal (PRS) generation formula, and when a PRS and the NPRS are transmitted through the same cell, the base station transmits, to a terminal, information indicating whether the PRS and the NPRS can be used together.

Embodiments of this application provide an uplink control channel transmission method and apparatus. At least one first-format uplink control channel and at least one second-format uplink control channel are generated, and the at least one first-format uplink control channel and the at least one second-format uplink control channel are transmitted in the first timeslot or subframe. In the process, there are only two formats of uplink control channels, so that uplink scheduling complexity is reduced.

A base station for a mobile telecommunications system has circuitry configured to communicate with at least one user equipment, wherein the circuitry is further configured to set a first subcarrier spacing for transmission of at least one synchronization signal; and set a second subcarrier spacing for transmission on a physical broadcast channel, wherein the first subcarrier spacing differs from the second subcarrier spacing.
