Embodiment 1

[0104] Embodiment 1 illustrates a flow chart of the first information, the first access detection and the first wireless signal, as attached figure 1 Shown.

[0105] In Embodiment 1, the user equipment in this application receives first information, and the first information is used to indicate the first time domain resource and the second time domain resource on the first sub-band. Time domain resources are reserved for the first wireless signal, and the second time domain resources are reserved for the second wireless signal; perform a first access detection to determine whether it is in the first time of the first sub-band Send the first wireless signal on the domain resource; send the first wireless signal on the first time domain resource of the first sub-band, not send it on the reserved time domain resource of the first sub-band Any wireless signal; or, giving up sending the first wireless signal on the first time domain resource of the first sub-band, and sending the firs...

Embodiment 2

[0348] Embodiment 2 illustrates a schematic diagram of the network architecture, as attached figure 2 Shown.

[0349] Embodiment 2 illustrates a schematic diagram of a network architecture according to this application, as attached figure 2 Shown. figure 2 It is a diagram illustrating the system network architecture 200 of NR 5G, LTE (Long-Term Evolution) and LTE-A (Long-Term Evolution Advanced). The NR 5G or LTE network architecture 200 may be referred to as EPS (Evolved Packet System) 200 by some other suitable term. EPS 200 may include one or more UE (User Equipment, user equipment) 201, NG-RAN (Next Generation Radio Access Network) 202, EPC (Evolved PacketCore, Evolved Packet Core) / 5G-CN (5G-Core Network, 5G core network) 210, HSS (Home Subscriber Server, home subscriber server) 220 and Internet service 230. EPS can be interconnected with other access networks, but these entities / interfaces are not shown for simplicity. As shown in the figure, EPS provides packet switchi...

Embodiment 3

[0357] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of the user plane and the control plane according to the present application, as attached image 3 Shown.

[0358] Attached image 3 Is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, image 3 Three layers are used to show the radio protocol architecture for user equipment (UE) and base station equipment (gNB or eNB): layer 1, layer 2, and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to as PHY301 herein. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between UE and gNB through PHY301. In the user plane, L2 layer 305 includes MAC (Medium Access Control, medium access control) sublayer 302, RLC (Radio LinkControl, radio link layer control protocol) sublayer 303, and PDCP (Packet Data...

Abstract

The invention discloses a method and a device in user equipment and a base station used for wireless communication. The user equipment receives first information, the first information is used for indicating a first time domain resource and a second time domain resource on a first sub-band, and the first time domain resource is reserved for the first wireless signal; a first access detection is performed to determine whether to transmit the first wireless signal on the first time domain resource of the first sub-band; the first wireless signal is sent on the first time domain resource of the first sub-band, and any wireless signal is not sent on the reserved time domain resource of the first sub-band; or, it is abandoned to send the first wireless signal on the first time domain resource of the first sub-band, and a first target wireless signal is sent on the reserved time domain resource of the first sub-band. The reserved time domain resource is located between the first time domainresource and the second time domain resource in a time domain.

Description

Technical field [0001] This application relates to a transmission method and device in a wireless communication system, in particular to a communication method and device that supports data transmission on an unlicensed spectrum (Unlicensed Spectrum). Background technique [0002] In the traditional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, data transmission can only occur on the licensed spectrum. However, with the sharp increase in business volume, especially in some In urban areas, licensed spectrum may be difficult to meet the demand for business volume. The communication on the unlicensed spectrum in Release 13 and Release 14 is introduced by the cellular system and used for downlink and uplink data transmission. To ensure compatibility with other access technologies on unlicensed spectrum, LBT (Listen Before Talk) technology was adopted by LAA (Licensed Ass isted Access) to avoid simultaneous occupation by multiple transmitters Interference c...
