[0001] This application is a divisional application of the following original application:

[0002] --The original application was filed on December 7, 2017.

[0003] --Original application number: 201780094865.0

[0004] --Original application title: A method and apparatus for use in user equipment and base stations for wireless communication Technical Field

[0005] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to communication methods and apparatus that support data transmission over unlicensed spectrum. Background Technology

[0006] In traditional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) systems, data transmission can only occur on licensed spectrum. However, with the rapid increase in traffic volume, especially in some urban areas, licensed spectrum may be insufficient to meet the demand. In Release 13 and Release 14, communication on unlicensed spectrum was introduced into cellular systems for downlink and uplink data transmission. To ensure compatibility with other unlicensed spectrum access technologies, LBT (Listen Before Talk) technology was adopted by LAA (Licensed Assisted Access) to avoid interference caused by multiple transmitters simultaneously occupying the same frequency resources.

[0007] Currently, technical discussions on 5G NR (New Radio Access Technology) are underway, with Massive MIMO (Multi-Input Multi-Output) becoming a research hotspot in next-generation mobile communications. In Massive MIMO, multiple antennas use beamforming to form a beam pointing in a specific spatial direction to improve communication quality. When considering the coverage characteristics brought about by beamforming, the traditional LBT scheme in LAA needs to be reconsidered. Summary of the Invention

[0008] When beamforming is applied to wireless transmission, the common practice is for the base station to configure multiple reference signals for multiple beams for the user equipment. The user equipment then performs channel measurements for each reference signal to obtain the optimal beam and sends the measurement results back to the base station to improve transmission performance. In the LAA discussions of Release-13 and Release-14, considering the uncertainty of channel occupancy and base station transmit power, the user equipment only assumes that the transmit power of the CRS (Cell Reference Signal) and CSI-RS (Channel State Information Reference Signal) within a single downlink burst (DL Burst) is the same. Therefore, the user equipment does not generate a single measurement result for CRS or CSI-RS measurements between different downlink bursts. In 5G systems, beamforming will be used extensively, and measurements for multiple beams will introduce more LBT processes, leading to measurement uncertainty and significant measurement latency.

[0009] To address the aforementioned problems, this application discloses a solution. Where there is no conflict, the embodiments and features described in the user equipment of this application can be applied to base stations, and vice versa. Where there is no conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other.

[0010] This application discloses a method used in a user equipment for wireless communication, characterized by comprising:

[0011] - Receive Q1 groups of indication information, each of which corresponds to a time slice, where Q1 is a positive integer;

[0012] - Receive Q2 reference signals in Q2 time slots of the first sub-band respectively;

[0013] - Send the first message;

[0014] Specifically, channel measurements for the Q2 reference signals are used to generate the first information. The channel measurements used to generate the first information are limited to the Q2 time slots within the Q1 time slots, where Q2 is a positive integer not greater than Q1. The Q1 indication information groups are used to determine the Q2 time slots, and at least one unoccupied multicarrier symbol is included between any two adjacent time slots in the Q2 time slots. Each of the Q1 indication information groups includes a positive integer number of indication information items, and all indication information items included in the Q1 indication information groups are dynamically configured. The Q1 indication information groups, the Q2 reference signals, and the first information are all transmitted through the air interface.

[0015] As an example, the advantage of the above method is that the first information only includes the measurement results of the Q2 reference signals, thereby enabling the base station to flexibly configure the Q2 reference signals to configure the antenna ports that need to be measured for the user equipment, thereby improving the flexibility and efficiency of LAA scenario for measuring different beams.

[0016] As an example, another advantage of the above method is that: the Q2 reference signals are located in the Q2 time slots, and the base station ensures that the transmission power of the Q2 reference signals is known to the user equipment, the user equipment averages the measurement results in the Q2 time slots to improve the accuracy of the measurement.

[0022] As an example, another advantage of the above method is that the Q2 time slices correspond to Q2 analog beams respectively, and thus the base station only needs one LBT under one analog beam, thereby reducing the number of LBTs and increasing the number of measurements and efficiency per unit time.

[0158] Example 3

[0159] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown.

[0160] Appendix Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and control plane. Figure 3 The radio protocol architecture for User Equipment (UE) and Base Station Equipment (gNB or eNB) is illustrated using 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the UE and gNB via PHY301. In the user plane, L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not illustrated, a UE may have several upper layers above L2 layer 305, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.). PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides header compression for upper layer packets to reduce radio transmission overhead, provides security through packet encryption, and provides handover support between gNBs to the UE. RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among UEs. MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and gNB is largely the same for physical layer 301 and L2 layer 305, but header compression functionality for the control plane is absent. The control plane also includes a Layer 3 (L3) RRC (Radio Resource Control) sublayer 306. RRC sublayer 306 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the gNB and the UE.
