Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a communication method and apparatus supporting data transmission over an Unlicensed Spectrum (Unlicensed Spectrum).

Background

In a conventional 3GPP (3rd generation partner Project) LTE (Long-term Evolution) system, data transmission can only occur on a licensed spectrum, however, with a drastic increase in traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communication over unlicensed spectrum in Release 13 and Release 14 was introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with other Access technologies over unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed assisted Access) to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. A transmitter of the LTE system employs a quasi-omni antenna to perform LBT. In addition, in a wireless communication system supporting multi-antenna transmission, a UE (User Equipment) generates and feeds back CSI (Channel Status Information) based on Channel and interference measurement to assist a base station to perform multi-antenna processing is a common technique. In LTE, CSI includes at least one of { CRI (CSI-RS Resource Indicator, Channel state information reference signal Resource indication), RI (Rank indication), PMI (Precoding matrix Indicator), CQI (Channel quality Indicator) }.

Currently, a technical discussion of 5G NR (New Radio Access Technology) is underway, wherein Massive MIMO (Multi-Input Multi-Output) becomes a research hotspot of next-generation mobile communication. In massive MIMO, multiple antennas form a beam pointing to a specific spatial direction through Beamforming (Beamforming) to improve communication quality, and when considering coverage characteristics caused by Beamforming, the conventional LAA technique needs to be reconsidered, such as CSI acquisition.

Disclosure of Invention

The inventor finds that in an NR system, massive MIMO will be used massively, and how to obtain accurate CSI is a key problem to be solved, so as to improve system capacity.

In view of the above, the present application discloses a solution. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.

The application discloses a method in user equipment for wireless communication, which is characterized by comprising the following steps:

receiving first configuration information, the first configuration information being used to indicate first time-frequency resources reserved for a first class of non-zero power reference signals;

Sending first channel state information, wherein the first channel state information corresponds to a first measurement process;

wherein the first measurement process is associated to the first time-frequency resource; the measurements for the first type of non-zero power reference signals are used to generate the first channel state information if the user equipment considers the first type of non-zero power reference signals to be transmitted in the first time-frequency resources, otherwise the first channel state information is independent of the first type of non-zero power reference signals.

As an embodiment, the problem to be solved by the present application is: in the NR system, since massive MIMO technology is used to transmit wireless signals, interference conditions in different beam directions may be greatly different, and beam-based LBT may more truly reflect the interference condition in a specific beam direction. However, beam-based LBT may cause some of all reference signals configured for channel and interference measurement to be unable to be transmitted, and thus the UE may not obtain all downlink channel estimates or interference estimates, and thus may not generate desired CSI or obtain accurate CSI.

As an embodiment, the essence of the above method is that a first type of non-zero power reference signal is used for channel measurement or interference measurement, the first channel state information is CSI; if the beam-based LBT passes, the base station transmits a first type of non-zero power reference signal, and the measurement of the first type of non-zero power reference signal is used for generating first channel state information; otherwise, the base station does not send the first type of non-zero power reference signal, and the measurement of the first type of non-zero power reference signal is not used for generating the first channel state information; the method has the advantages that the channel parameters included in the first channel state information under the condition that the base station sends the first type of non-zero power reference signals and the channel parameters included in the first channel state information under the condition that the base station does not send the first type of non-zero power reference signals can be different, so that corresponding accurate CSI can be obtained according to the sending condition of actual reference signals.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (gNB or eNB) 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 PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for physical layer 301 and L2 layer 305, but without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3(L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.
