Embodiment 1

[0078] Embodiment 1 exemplifies the first control signal and the first wireless signal according to the present application, as shown in the attached figure 1 shown. attached figure 1 In , each box represents a step. In Embodiment 1, the user equipment in this application receives a first control signal, and the first control signal indicates K candidate physical control channels corresponding to the first time-frequency resource index, where K is a positive integer; receiving the second control signal, the second control signal indicates at least one of the first time slot and the second time slot; monitor the K candidate physical control channels on the first time-frequency resource subset, and the first time-frequency resource subset The set is the time-frequency resource corresponding to the first time-frequency resource index on the first time slot; the K candidate physical control channels are monitored on the second time-frequency resource subset, and the second time-...

Embodiment 2

[0202] Embodiment 2 illustrates a schematic diagram of a network architecture according to the present application, as attached figure 2 shown. figure 2 It is a diagram illustrating NR5G, LTE (Long-Term Evolution, long-term evolution) and LTE-A (Long-Term Evolution Advanced, enhanced long-term evolution) system network architecture 200 . The NR 5G or LTE network architecture 200 may be referred to as an EPS (Evolved Packet System, 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. The EPS may be interconnected with other access networks, but these entities / interfaces are not shown for simplicity. As shown, the EPS provides packet-switched services, however those skilled in ...

Embodiment 3

[0208] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached image 3 shown. image 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, image 3 The radio protocol architecture for user equipment (UE) and base station equipment (gNB or eNB) is shown in three layers: 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 herein as PHY 301 . Layer 2 (L2 Layer) 305 is above PHY 301 and is responsible for the link between UE and gNB through PHY 301 . In the user plane, the L2 layer 305 includes a MAC (Medium Access Control, medium access control) sublayer 302, an RLC (RadioLink Control, radio link layer control protocol) sublayer 303, and a PDCP (Packet Da...

Abstract

The invention discloses a base station, and a method and a device for wireless communication in user equipment. The method comprises the following steps of enabling The the user equipment to receivesa first control signal, wherein the a first control signal indicates K candidate physical control channels corresponding to the first time-frequency resource index; receiving a second control signal,wherein the second control signal indicates at least one of the first time slot and the second time slot; and monitoring the K candidate physical control channels on a first time-frequency resource subset and a second time-frequency resource subset, wherein the first time-frequency resource subset and the second time-frequency resource subset are time-frequency resources corresponding to the firsttime-frequency resource index on the first time slot and the second time slot respectively. According to the invention, time-frequency resources occupied by a physical control channel in different time slots, subframes or frames or adopted modulation and coding schemes can be configured more flexibly.

Description

technical field [0001] The present application relates to a wireless signal transmission scheme in a wireless communication system, in particular to a method and device for multi-antenna transmission and unlicensed spectrum. Background technique [0002] In the traditional 3GPP (3rd Generation Partner Project, 3rd Generation Partnership Project) LTE (Long-term Evolution, long-term evolution) system, data transmission can only occur on the licensed spectrum. However, with the rapid increase of traffic, especially In some urban areas, licensed spectrum may be difficult to meet traffic demands. 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. In order to ensure compatibility with other access technologies on unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) to avoid multiple transmitters occupying the same interf...
