Feature, element, function or part.
For the ease of explaining, some embodiments of the present invention will be introduced using millimetre-wave attenuator as background herein, and
Art in Long Term Evolution/Long Term Evolution-advanced (LTE/LTE-A) formulated using such as third generation partner program (3GPP)
Language, however, as will be understood by the skilled person in the art, embodiments of the invention are not limited to follow the channel radio of 3GPP formulations
Believe the wireless communication system of agreement, be also not necessarily limited to millimetre-wave attenuator, but any nothing that Similar Problems be present can be applied to
In line communication system, such as WLAN, or following other communication systems developed etc..
Equally, the terminal device in the disclosure can be user equipment (UE) or appoint with radio communication function
What terminal, include but is not limited to, mobile phone, computer, personal digital assistant, game machine, wearable device, vehicular communication equipment,
Machine to machine communication equipment and sensor etc..The term terminal device can be with UE, movement station, subscriber station, movement eventually
End, user terminal or wireless device used interchangeably.In addition, the network equipment can be network node, such as node B (Node B, or
Person NB), base transceiver station (BTS), base station (BS) or base station sub-system (BSS), relaying, remote radio heads
(RRF), access node (AN), access point (AP) etc..
The example wireless communication system 100 for the method that can be implemented within embodiment of the disclosure is shown in figure ia
Schematic diagram.Wireless communication system 100 can include one or more network equipment 101.For example, in this example, network
Equipment 101 can be presented as base station, such as the node B (eNodeB, or eNB) of evolution.It should be appreciated that the network equipment
101 can also be presented as other forms, for example, node B (Node B, or NB), base transceiver station (BTS), base station (BS),
Or base station sub-system (BSS), repeater etc..The network equipment 101 can be that multiple terminals within its coverage are set
Standby 102-105 provides dedicated radio link.
In one embodiment, the network equipment 101 can support multiple frequency ranges.For example, the network equipment can operate in mesh
Preceding cellular communication band, millimeter wave frequency band can also be operated in utilize bigger bandwidth.Terminal device is according to its energy that communicates
The difference of power, single or multiple frequency ranges can be operated in.
As it was previously stated, the communicating requirement ADC of millimeter wave frequency band has higher sample rate.Current system is supporting millimeter wave
Lot of challenges be present in the communication aspects of frequency range.For example, in existing cellular band communication system, lead in the ADC of receiver deployment
Often with there is high-resolution.However, the ADC of the type is unsuitable for millimetre-wave attenuator.Main cause has two：(i) high score used
Resolution ADC (for example, 12 bit A/D C) can not provide sufficiently high sample rate simultaneously to tackle the width in millimeter-wave communication system
Transmission bandwidth；(ii) for UE equipment, dispose (for example, a few G samplings per second) at a high speed and high-resolution ADC is burden
Do not rise.
To tackle problem above, UE can dispose the ADC of low resolution high sampling rate with millimeter wave frequency band reception broadband
Signal.The ADC of low resolution has lower cost than high-resolution ADC, and can provide high sampling rate.However, this
Cause big quantizing distortion.
It is proposed in the disclosure, in order to support cellular band communication and millimeter wave frequency band communication, terminal device can be disposed
Two groups of ADC with different resolution (and sample rate).For example, for the communication in below 6GHz low-frequency range, communication bandwidth
Less big, corresponding sample rate is not high, can quantify received signal using high resolution A/D C in this case, to protect
Demonstrate,prove the quality of sampled signal.In order to tackle the communication in 28GHz or 60GHz millimeter wave frequency band, low point of high speed can be used
The ADC of resolution, to meet the sample rate requirement to reception signal.Therefore, the scheme proposed is obtained in hardware cost and performance
Between compromise.
Equipment for being exclusively used in millimetre-wave attenuator, can also be only with a set of high-speed low-resolution in order to reduce cost
ADC, to meet to the requirement of the sample rate of reception signal.
Inventor has found that：When terminal device uses the ADC of different resolution, the signal of reception signal and mistake
True and noise ratio (SDNR) is different, and the SDNR performance differences change with transmission signal to noise ratio (SNR) difference.In fig. ib,
Show in Figure 1A wireless communication system 100, in the case of the ADC using different resolution, terminal device (such as terminal
102) SDNR of reception signal.In Figure 1B example, the communication system 100 is that single user-multiple-input, multiple-output (SU-MIMO) are orthogonal
Frequency division multiplexing (OFDM) millimeter-wave communication system.But as skilled in the art will understand, embodiment of the disclosure is not
It is limited to this.
In Figure 1B example, it is assumed that use OFDM and SU-MIMO technologies in downlink, wherein eNB has 16 days
Line and UE has individual antenna.Ofdm signal includes 2048 subcarriers, and in each subcarrier, information bit is mapped to
16QAM constellations.Further, it is assumed that UE ADC input reference signal, which is -1V, arrives 1V.
The reception SDNR performances under 3 bits, 4 bits, 5 bits and 12 bit A/D C definition cases are compared in fig. ib.
As shown in Figure 1B, in low transmission signal to noise ratio region, such as transmission SNR is less than 10dB region, corresponding to the ADC of different resolution
SDNR performances are closer to each other.This result means the scene for noise limited, in receiver deployment low resolution A/D C not
Cause obvious performance loss.Therefore, deployment low resolution A/D C advantageously can bring hardware cost to reduce in this case.
For high SNR regions, example SNR as shown is higher than 10dB region, is born by the ADC quantizing distortions introduced as main performance
Load.In order that the UE with low resolution A/D C obtains the SNDR same with high ADC resolution ratio, need use bigger in base station side
Transimission power be transmitted.In other words, for specific Modulation and Coding Scheme, in order to obtain the reception SDNR of needs, with
High resolution A/D C scene is compared, and eNB will need to use higher transmit power.For example, if UE is deployed with 4 bits
The ADC of resolution ratio, then in order to reach 15dB SDNR in UE sides, the transmission SNR of base station side needs 17.5dB.This is than with 12 ratios
The high 2.5dB of transmit power required by the ADC of special resolution ratio UE.
Therefore, it is desirable to base station can design adaptive transmission plan according to UE ADC resolution ratio.However, at present not
There is the mechanism for supporting the exchange ADC information between UE and eNB.
Itd is proposed in the disclosure, terminal device reports the information relevant with its ADC resolution ratio to the network equipment, so that network
Equipment can determine the configured transmission for the terminal device, for example, transmit power, diversity scheme, Modulation and Coding Scheme etc..Its
Middle determination diversity scheme can include, for example, determining whether use beam shaping (BF) for the transmission of the terminal device.
Communicated for millimeter wave frequency band, UE can dispose ADC (points of such as 4 bits or 5 bits of comparatively low resolution
Resolution), and communicated for low-frequency range, UE can keep high-resolution ADC.Its key benefit is at least embodied in following tripartite
Face：(i) ADC of low resolution is utilized, using the teaching of the invention it is possible to provide much higher sampling rate, this is particularly suitable for large transmission bandwidth
Millimetre-wave attenuator；(ii) by being lowered in millimeter wave frequency band ADC of the deployment with relatively low resolution ratio, hardware cost
The level that UE equipment can be born；(iii) for the communication of low-frequency range, high-resolution ADC is kept so that remain able to provide
Sampled signal with low quantizing distortion.
In accordance with an embodiment of the present disclosure, in order to perform the downlink transmission in millimeter wave frequency band, base station can be obtained
Take the resolution information in the ADC of UE equipment sidepiece administration.Based on the resolution information, the base station can be performed for downlink
The appropriate transmission plan of data transfer.

Shown below in conjunction with accompanying drawing 10 in an example usage scenario, the property that can be obtained using embodiment of the disclosure
Can gain.In the exemplary scene, it is assumed that implement embodiment of the disclosure in Figure 1A wireless communication system 100, and it is false
The fixed system 100 is multi-user-multiple-input, multiple-output (MU-MIMO) OFDM millimeter-wave communication systems.
In this example, consider to use OFDM and MU-MIMO technologies in downlink, and wherein the network equipment 101 is
ENB with 16 antennas.The eNB services the UE of 4 single antenna simultaneously.Ofdm signal includes 2048 subcarriers, each
In subcarrier, information bit is mapped to 16QAM constellations.It is assumed that eNB transmission signal to noise ratio (SNR) is limited to 25dB.Show at this
In example, it is assumed that each UE disposes the ADC of 4 bits, and UE ADC input reference signal is that -1V arrives 1V.
In this example, in order to solve common-channel interference, it is considered as zero-forcing beamforming technology.In addition, eNB always according to
UE ADC resolution ratio is based on specific quasi- chaining pin and distributes transimission power to each UE.In addition, coding and modulation scheme can be according to connecing
Receive SDNR and do adaptability regulation.Therefore, in Computer Simulation, UE reception SDNR targets are set first.Then eNB selections are suitable
When transmission plan to realize predetermined SDNR targets, while reduce power consumption using transmit power as few as possible.
Under conditions of the system architecture and emulation are set, SDNR performance curves as shown in Figure 10 are obtained.Wherein compare
SDNR performances in the case of following two：
Situation 1：The mechanism proposed using embodiment of the disclosure, eNB know the ADC disposed at UE resolution ratio；
Situation 2：The mechanism not proposed using embodiment of the disclosure, the ADC disposed at UE resolution ratio is not eNB
It is known.In this case, eNB assumes that UE disposes the ADC of 12 bits, as in classical scenario.
The line represented in Figure 10 with legend 1001 represent eNB can know ADC resolution informations in the case of most differential
Receive SDNR desired value.The curve is used as baseline, to show whether UE target SDNR reaches.Especially, if UE most
Poor reception SNR is higher than the curve, then it is assumed that UE intended recipient SDNR reaches, otherwise it is assumed that UE intended recipient SDNR does not reach
Arrive.The line represented with legend 1002 represent with 1 corresponding computer artificial result of situation, and represented in Figure 10 with legend 1003
Line represent and 2 corresponding computer artificial result of situation.
By Figure 10, it can be seen that, in the case of ADC information is unknown (i.e. situation 2), on average, intended recipient SDNR is not
It can reach.In addition as seen from Figure 10, when intended recipient SDNR is smaller, performance loss unobvious.Because when SNR is not high
(such as when SNR is less than 10dB), the ADC of various resolution ratio has similar performance (referring to Figure 1B result).However as
Intended recipient SDNR increases, sending SNR should be increased.In order to obtain intended recipient SDNR, the UE for disposing 4 bit A/D C,
ENB should use bigger transmit power.And for situation 2, eNB excessively high have estimated UE ability (it is assumed that it has 12 ratios
The ADC of special resolution ratio), and power is mistakenly saved, cause the performance loss of UE sides.
Moreover, as shown in Figure 10, when intended recipient SDNR is set to 16dB, obtained in intended recipient SNR and situation 2
Averagely there is 2dB difference between the worst SDNR obtained.As it is known, coding and modulation scheme are adaptable to receive SDNR.This meaning
Taste the modulation and encoding scheme for being adapted to the fixation for receiving SDNR, will have when eNB does not know UE ADC resolution ratio big
Bit error rate.Because it is lower 2dB than predetermined target SNR in this case, to receive SDNR.But for situation 1, and be not present
This phenomenon.Because the mechanism eNB based on proposition has known UE ADC information, so as to have adjusted transmit power.
