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 method and apparatus for supporting reference signal based channel measurement on 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.

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 LBT scheme in LAA needs to be considered again.

Disclosure of Invention

When beamforming is applied to wireless transmission, a general method is that a base station configures a plurality of reference signals for a plurality of beams for a user equipment, and then the user equipment performs channel measurement on the plurality of reference signals respectively to obtain an optimal beam and sends a measurement result to the base station, so as to improve transmission performance. In the LAA discussions of Release-13 and Release-14, considering the uncertainty of the Channel occupancy and the uncertainty of the base station transmission power, the ue only assumes that the transmission powers of the CRS (Cell Reference Signal) and the CSI-RS (Channel State Information Reference Signal) in one downlink Burst (DL Burst) are the same, and the ue does not generate a measurement result for the measurement of the CRS or CSI-RS between different downlink bursts and report the measurement result. Meanwhile, the UE (User Equipment) may average Measurement results of DRS (Discovery Reference Signal) in multiple DMTCs (Discovery Signals Measurement Configuration) occupancy to obtain mobility management for Layer 3(Layer 3) and path loss (Pathloss) for uplink power control.

In a 5G system, beamforming will be used in a large scale, and a simple way is to design independent layer 1 and layer 3 measurement processes for multiple beams; however, due to LBT and the presence of multiple beams, this can cause severe measurement delay; the measurement scheme for multiple beams, or multiple beam groups LAA, needs to be redesigned.

In view of the above, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

The application discloses a method used in a user equipment for wireless communication, characterized by comprising:

-receiving Q indication information, respectively associated to Q time windows, said Q being a positive integer greater than 1;

-receiving Q target reference signals in the Q time windows of the first sub-band, respectively;

the Q pieces of indication information respectively include Q first domains, and for any two target reference signals in the Q pieces of target reference signals, the transmission powers of the any two target reference signals can be considered to be equal only when the values of the first domains in the indication information corresponding to the any two target reference signals are equal; the Q pieces of indication information are all transmitted through an air interface.

As an embodiment, the above method is characterized in that: the base station dynamically indicates whether the Q target reference signals transmitted in the corresponding Q time windows are DRS or other RSs through the Q pieces of indication information; when the target reference signal indicated by the first domain is DRS, the target reference signal can be regarded as adopting the same transmission power, and then the target reference signal can be used for determining uplink transmission power and mobility management of layer 3.

As an example, another peculiarity of the above method consists in: the first domain can also dynamically indicate antenna port information adopted by the target reference signal, so as to indicate a transmit beamforming vector corresponding to the target reference signal, and only the path loss of the target reference signal belonging to one transmit beamforming vector can be averaged.

According to an aspect of the present application, the above method is characterized in that the Q pieces of indication information are respectively used to determine whether the target reference signals transmitted in the Q time windows on the first sub-band are discovery reference signals.

As an example, the above method has the benefits of: the CSI-RS and the DRS often adopt the same Pattern (Pattern) in one PRB (Physical Resource Block), and the DRS often scans in multiple beam directions due to the problem of beam coverage, so that the time domain Resource occupied by the DRS is fixed; since LBT is required for any transmission in the LAA system, the configuration of the fixed DRS may cause the base station to perform LBT continuously in multiple beam directions to ensure the transmission of the DRS. The method for dynamically indicating the type of the target reference signal provided by the application can ensure the flexibility of the base station to the greatest extent, and when no UE needing layer 3 measurement exists in one beam direction, the base station can transmit CSI-RS to the resource originally reserved for DRS, so that the layer 1 measurement accuracy for scheduling service is improved.

In embodiment 14, one antenna port group includes a positive integer number of antenna ports; one antenna port is formed by superposing antennas in a positive integer number of antenna groups through antenna Virtualization (Virtualization); one antenna group includes a positive integer number of antennas. One antenna group is connected to the baseband processor through one RF (Radio Frequency) chain, and different antenna groups correspond to different RF chains. The mapping coefficients of all antennas in the positive integer number of antenna groups included by a given antenna port to the given antenna port constitute a beamforming vector corresponding to the given antenna port. Mapping coefficients of a plurality of antennas included in any given antenna group in the positive integer number of antenna groups included in the given antenna port to the given antenna port constitute an analog beamforming vector of the given antenna group. And the analog beamforming vectors corresponding to the positive integer number of antenna groups are arranged diagonally to form an analog beamforming matrix corresponding to the given antenna port. The mapping coefficients of the positive integer number of antenna groups to the given antenna port constitute a digital beamforming vector corresponding to the given antenna port. The beamforming vector corresponding to the given antenna port is obtained by multiplying an analog beamforming matrix corresponding to the given antenna port by a digital beamforming vector. Different antenna ports in one antenna port group are formed by the same antenna group, and different antenna ports in the same antenna port group correspond to different beam forming vectors.

Two antenna port groups are shown in fig. 14: antenna port group #0 and antenna port group # 1. The antenna port group #0 is composed of an antenna group #0, and the antenna port group #1 is composed of an antenna group #1 and an antenna group # 2. Mapping coefficients of a plurality of antennas in the antenna group #0 to the antenna port group #0 constitute an analog beamforming vector #0, and mapping coefficients of the antenna group #0 to the antenna port group #0 constitute a digital beamforming vector # 0. Mapping coefficients of the plurality of antennas in the antenna group #1 and the plurality of antennas in the antenna group #2 to the antenna port group #1 constitute an analog beamforming vector #1 and an analog beamforming vector #2, respectively, and mapping coefficients of the antenna group #1 and the antenna group #2 to the antenna port group #1 constitute a digital beamforming vector # 1. A beamforming vector corresponding to any antenna port in the antenna port group #0 is obtained by a product of the analog beamforming vector #0 and the digital beamforming vector # 0. A beamforming vector corresponding to any antenna port in the antenna port group #1 is obtained by multiplying an analog beamforming matrix formed by diagonal arrangement of the analog beamforming vector #1 and the analog beamforming vector #2 by the digital beamforming vector # 1.

For one embodiment, one antenna port group includes one antenna port. For example, the antenna port group #0 in fig. 14 includes one antenna port.

As a sub-implementation of the foregoing embodiment, the analog beamforming matrix corresponding to the one antenna port is reduced to an analog beamforming vector, the digital beamforming vector corresponding to the one antenna port is reduced to a scalar, and the beamforming vector corresponding to the one antenna port is equal to the analog beamforming vector corresponding to the one antenna port. For example, the digital beamforming vector #0 in fig. 13 is reduced to a scalar, and the beamforming vector corresponding to the antenna port in the antenna port group #0 is the analog beamforming vector # 0.

For one embodiment, one antenna port group includes a plurality of antenna ports. For example, the antenna port group #1 in fig. 14 includes a plurality of antenna ports.

As a sub-embodiment of the above embodiment, the plurality of antenna ports correspond to the same analog beamforming matrix and different digital beamforming vectors.

As an embodiment, the antenna ports in different antenna port groups correspond to different analog beamforming matrices.
