Description

Method, device and terminal for reporting reference information

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for transmitting a signal, a scheduling method, a terminal, and a network side device.

Background technique

In the current communications field, there are more unlicensed spectrum resources than licensed spectrum resources. The unlicensed spectrum has no constraints on the use of wireless communication systems and operators, so unlicensed spectrum can also be referred to as shared spectrum. Long-term Evolution (LTE) devices use unlicensed spectrum to effectively utilize unlicensed spectrum resources and provide more efficient wireless access to meet the growing demand for mobile broadband services.

In a carrier aggregation system of LTE, an Evolved Node B (eNodeB or an eNB) generates a power control command according to a maximum transmit power and a power headroom of a current serving cell reported by a user equipment, thereby scheduling a wireless communication device. Transmit power. Moreover, in the prior art, the user equipment reports the remaining amount between the maximum transmit power and the actual transmit power to the eNB only after transmitting the uplink data, and simultaneously reports the determined maximum transmit power to the eNB. The maximum transmit power is not sent to the eNB until the user equipment sends the uplink data.

Wireless communication devices are subject to specific regulatory rules when used on a shared spectrum. For example, according to the current ETSI EN 301 893, when a wireless communication device is used on a shared spectrum, it is necessary to determine whether the channel is idle by energy detection; if the channel is idle, it can be used, and if the channel is occupied, it cannot be used. The rules for determining whether the channel is idle are as follows:

The wireless communication device detects whether the received energy exceeds the threshold TL of the Clear Channel Assessment (CCA) in the transmission channel, and if the received energy exceeds the threshold TL, it is determined that the transmission channel is occupied, otherwise the channel is determined to be occupied. The transmit channel is idle. Among them, it is assumed that the receiving antenna gain is 0 dB, TL = P _{constant -} P _H . P _H is the transmission power of the wireless communication device on the transmission channel, and the unit is the equivalent isotropic radiation power dBm. P _constant is the power detection constant of the occupied channel in the shared spectrum channel. In the current specification of ETSI EN 301 893, P _constant = -73dB/MHz+23. Further, from TL = P _{constant -} P _H , P _H = P _{constant -} TL can be obtained.

As can be seen from the above description, if the eNB configures the user equipment to have a large transmit power, the threshold TL is small, and the possibility that the received energy exceeds the threshold TL is greater in the same environment. The chance of the user equipment occupying the shared spectrum is small. When the eNB configures the transmit power in the shared spectrum channel for the user equipment, it is difficult to timely and correctly schedule the transmit power of the user equipment. Therefore, the scheduling of the user equipment by the eNB in this case is often blind. As a result, it is difficult for the user equipment to occupy the shared spectrum channel, and the eNB schedules an inefficient technical problem.

An embodiment of the present invention provides a method for transmitting a signal. Referring to FIG. 1, a possible LTE communication system architecture suitable for transmitting signals in this embodiment is provided. The communication system architecture includes: user equipment (English: User Equipment; UE for short) and network side equipment. In the embodiment of the present invention, the UE may be a mobile phone, a smart watch, or the like, and the present application does not specifically limit the present application. The network side device may be a base station, an enhanced base station, a cell, or a relay. The base station is an evolved base station (Evolutional Node B, hereinafter referred to as eNB or e-NodeB) in LTE. The present invention is not limited, but for convenience of description, the following embodiments will be described by taking an eNB as an example.

The following describes the method for transmitting a signal in this embodiment from the UE side. Referring to FIG. 2, it is a flowchart of a method for transmitting a signal in the embodiment. The method includes:

S101: The user equipment receives and detects a signal in the shared spectrum channel, and obtains a detection result.

S102: The user equipment determines, according to the detection result, a first transmit power that can be sent when the user equipment sends a signal in the shared spectrum channel.

S104: The user equipment receives scheduling indication information that is generated by the network side device and is generated by the network side device according to the first transmit power.

S105: The user equipment sends a signal in the shared spectrum channel according to the scheduling indication information.

Specifically, in the embodiment of the present invention, the UE enters the signal in the shared spectrum channel in S101. Line detection, specifically can include:

The UE in the embodiment of the present invention can detect the power of the received signal in the shared spectrum channel, and obtain the signal in the channel, because a plurality of wireless communication devices may transmit information and transmit signals. Receive power and use received power as a test result. The detection of the received power by the UE is similar to the prior art, and is not described here. In order to facilitate the subsequent description, it is assumed that the detected received power is P _a and P _a is a positive number.

In addition to detecting the received power of the received signal in the shared spectrum channel, the embodiment of the present invention may further include:

The user equipment receives a signal in the shared spectrum channel, and detects a received power and a signal type of a signal in the shared spectrum channel, and uses the detected received power and a signal type as the detection result.

Specifically, the multiple radio communication devices in the shared spectrum transmit information at the same time. Therefore, the UE in the embodiment of the present invention can detect the signal receiving power of the received wireless communication device, and can also detect the signal type of the signals. The received power and the received signal type are used as detection results.

The signal type in the embodiment of the present invention is used to indicate at least one of types of wireless communication systems to which an operator in a shared spectrum channel belongs or a signal in a shared spectrum channel belongs to. In a specific implementation process, the signal type may only indicate the operator to which the signal in the shared spectrum channel belongs, such as mobile or Unicom. The signal type may also indicate only the wireless communication system to which the signal in the shared spectrum channel belongs, such as an LTE system, a wifi system, or the like. The signal type can also indicate to the operator and the wireless communication system at the same time. A person of ordinary skill in the art to which the present invention pertains may make selections according to actual conditions, and the present application does not specifically limit them.

In addition, when detecting the received power and the received signal type, the UE may first detect the received power and then detect the received signal type. It is also possible to detect the type of the received signal first and then detect the received power. The UE can also detect the received power and the received signal type at the same time. A person of ordinary skill in the art to which the present invention pertains may make selections according to actual conditions, and the present application does not specifically limit the present application.

In the embodiment of the present invention, the type of the received signal includes multiple possibilities. For convenience of description, it is assumed that the operator to which the UE belongs is the first operator. The first carrier provides services such as access, charging, and deregistration for the UE, and the signal to be sent by the UE is specifically a signal of the first wireless communication system operated by the first operator, where the first wireless communication system is, for example, an LTE system. , WiFi system, etc. In the embodiment of the present invention, when the signal type indicates the operator to which the signal in the shared spectrum channel belongs, the signal type includes but is not limited to the following:

11. The signal to be sent by the user equipment is the same as the carrier signal type;

12. The signal to be sent with the user equipment is a different carrier signal type.

When the signal type specifically indicates the wireless communication system to which the signal in the shared spectrum channel belongs, the signal types include but are not limited to the following:

21. The signal to be sent by the user equipment is the same as the signal type of the wireless communication system;

22. The signal to be transmitted with the user equipment is a signal type of a different wireless communication system.

For example, the signal of the UE is sent by the LTE system. When the signal in the shared spectrum is also sent by the LTE system, the signal type at this time is the same as the type of the wireless communication system; when the signal in the shared spectrum is sent by the wifi system. Then, the signal type at this time is the type of different wireless communication system.

When the signal type specifically indicates the operator and the wireless communication system to which the signal in the shared spectrum channel belongs, the signal types include but are not limited to the following:

31. The signal to be sent by the user equipment is the same as the signal type of the wireless communication system of the operator;

32. The signal to be sent by the user equipment is a signal type of a carrier-specific wireless communication system;

33. The signal to be sent by the user equipment is a signal type of a different carrier and a wireless communication system;

34. The signal to be sent by the user equipment is a signal type of a different carrier-specific wireless communication system.

Since the operator to which the UE belongs is the first carrier, when the received signal is a signal from the first wireless communication system operated by the first operator, for the UE, it is the same as the signal of the wireless communication system of the operator; When the received signal is a signal from the second wireless communication system operated by the first operator, for the UE, it is a signal of the same wireless communication system as the carrier; when the received signal is the first wireless communication operated by the second operator The signal of the system is a signal of the different operator and the wireless communication system for the UE; and when the received signal is the signal of the second wireless communication system operated by the second operator, it is a different operation for the UE. The signal of a different wireless communication system. The second wireless communication system is different from the first wireless communication system.

In order to facilitate the subsequent description, when the detection result specifically includes the received power and the signal type, it is also assumed that the detected received power is P _a .

Next, in S102, the UE determines the first transmit power to be transmitted to the eNB according to the detection result.

Specifically, in the embodiment of the present invention, how to determine the first transmit power for the UE includes:

Further, the second maximum transmit power is a power obtained by the user equipment occupying the channel in the shared spectrum channel minus the received power;

Or the maximum transmit power specified in the protocol followed by the user equipment.

When the second maximum transmit power is the power obtained by the user equipment occupying the channel in the shared spectrum channel minus the received power, in order to determine whether the UE can transmit signals in the shared spectrum at this time, according to ETSI EN 301 893 It is stipulated that the UE needs to compare the magnitude relationship between the received power and the current reference threshold. Specifically, ETSI EN 301 893 stipulates that "the wireless communication device detects whether the received energy exceeds the threshold TL of the Clear Channel Assessment (CCA) in the transmission channel, and if the received energy exceeds the threshold TL, it is determined. The transmit channel is occupied, otherwise the transmit channel is determined to be idle. The transmit antenna gain is assumed to be 0 dB, TL = P _{constant -} P _{H .} P _H is the transmit power of the wireless communication device on the transmit channel, and the unit is Effective omnidirectional radiation power dBm.".

The UE compares the magnitude relationship of P _a and TL according to the received power P _a in the detection result. When the received power P _a ≤ TL, the UE can start transmitting information in the shared spectrum. When the received power P _a exceeds the reference threshold TL, the UE cannot transmit information in the shared spectrum.

In the embodiment of the present invention, if Pa>TL, in order to enable the UE to occupy the shared spectrum and transmit a signal in the shared spectrum, the UE needs to calculate and obtain the second maximum transmit power. The second maximum transmit power is the maximum power of the signal transmitted when the UE user equipment can occupy the shared spectrum channel.

Specifically, the condition that the UE transmits a signal in the shared spectrum channel is that P _a does not exceed the current reference threshold TL. Therefore, in order to enable the UE to transmit signals in the channel sharing the spectrum, the UE desires that the current reference threshold TL minimum is not lower than the received power, that is, TL ≥ P _a . The TL is determined by the transmit power of the UE, specifically TL=P _{constant –} P _H . Therefore, the TL≥P _a and TL = P _constant -P _H two formulas can be obtained: when the transmission power _{_{_{P H ≤P constant -P a, TL≥P}}} a set up, the UE can obtain further transmitted in a shared spectrum Signal opportunity.

Therefore, subtracting the power obtained by the received power P _a from the power detection constant P _{constant of the} occupied channel in the shared spectrum channel is the second maximum transmit power in the implementation of the present invention. It is determined that any one of the power values less than or equal to the second maximum transmission power is the first transmission power. For example, if the second maximum transmit power is 23 dBm, the UE may select powers such as 23 dBm, 19.3 dBm, or 15 dBm to report to the eNB as the first transmit power.

Then, when the UE transmits at the first transmission power, it is guaranteed that TL ≥ P _a , so as to comply with the provisions of UE ETSI EN 301 893, the signal can be transmitted in the shared spectrum.

It should be understood by those skilled in the art that, in a specific implementation process, when the protocol specifies that the received power is equal to the reference threshold TL, the UE may occupy the shared spectrum, and then the first transmit power may be any power less than or equal to the second maximum transmit power. When the protocol specifies that the received power is less than the reference threshold TL, the UE may occupy the shared spectrum, and the first transmit power also needs to be any power smaller than the second maximum transmit power. The person skilled in the art to which the present application belongs is set according to the actual situation, and both cases are within the scope of implementation of the present invention.

In the embodiment of the present invention, the power detection constant of the occupied channel of the UE in the shared spectrum channel is related to the protocol followed by the UE, as specified in ETSI EN 301 893.

When the signal type of the signal detected by the UE is not distinguished in the protocol, the power detection constant is specifically the first power detection constant.

When the protocol distinguishes the signal type by the operator and the wireless communication system to which the signal in the shared spectrum channel belongs, the signal type includes four types of signals, such as the same wireless communication system as the operator. If the signal type is the signal type of the wireless communication system with the signal to be sent by the UE, the power detection constant is specifically the second power detection constant; if the signal type is the same as the signal to be sent by the UE, the carrier is different from the carrier. When the signal type of the communication system is used, the power detection constant is specifically the third power detection. Constant; if the signal type is different from the signal type of the wireless communication system of the carrier to be transmitted, the power detection constant is the fourth power detection constant; if the signal type is specifically different from the signal to be sent by the UE When the signal type of the wireless communication system is different, the power detection constant is the fifth power detection constant.

When the protocol distinguishes the signal type by the operator to which the signal in the shared spectrum belongs, the signal type includes two types of signals, such as the same carrier. If the signal type is specifically the same as the signal type of the carrier to be sent by the UE, the power detection constant is a sixth power detection constant; if the signal type is specifically a signal type different from the carrier to be transmitted by the UE, The power detection constant is the seventh power detection constant.

When the signal type is distinguished by a wireless communication system to which a signal in a shared spectrum belongs, the signal type includes two types of signals, such as a wireless communication system. If the signal type is specifically the same as the signal type of the wireless communication system, the power detection constant is the eighth power detection constant; if the signal type is specifically different from the signal to be sent by the UE, the signal type of the wireless communication system The power detection constant is the ninth power detection constant.

In the specific implementation process, the above eight power constants are related to the protocol specifically followed by the UE. For example, when the UE complies with the provisions of ETSI EN 301 893, the first power constant is specifically -73 dB/MHz + 23. And, in order to distinguish between different signal types, the second power detection constant, the third power detection constant, the fourth power detection constant, and the fifth power detection constant are not completely the same. For example, the second power constant is -73dB/MHz+23, the third power constant is -76dB/MHz+23, the fourth power constant is -79dB/MHz+23, and the fifth power constant is -82dB/MHz+23. The sixth power detection constant is different from the seventh power detection constant. For example, the sixth power constant is -73 dB/MHz + 23, and the seventh power constant is -76 dB/MHz + 23. The eighth power detection constant is different from the ninth power detection constant. For example, the eighth power constant is -73 dB/MHz + 23, and the ninth power constant is -76 dB/MHz + 23.

Alternatively, the second maximum transmit power may also be the maximum transmit power specified in the protocol that the UE complies with. For example, the protocol that the UE complies with specifies that when the UE transmits a signal in the shared spectrum channel, the maximum transmit power that can be transmitted is 25dBM, etc., then the first transmit power can be 25dBM, 23dBM, and the like. Of course, the maximum transmit power of the protocol can be specified as 30dBM, 27dBM, etc., and no limitation is imposed on this.

Then, the UE reports the first transmit power to the eNB in S103, so that the eNB schedules the UE with reference to the first transmit power, and determines scheduling indication information.

In the embodiment of the present invention, the manner in which the UE reports the first transmit power to the eNB is:

Specifically, when the MAC control unit (CE) in the Media Access Control (MAC) Protocol Data Unit (PDU) is not zero bytes, the UE may transmit the first transmit power. Carry in the MAC CE. Then, when the UE reports the MAC PDU to the eNB in the primary carrier uplink channel, the first transmit power can be reported to the eNB.

In addition to carrying the first transmit power in the MAC CE, the first transmit power may also be carried in the physical layer signaling reported by the UE to the eNB. Then, when the UE reports the physical layer signaling to the eNB in the uplink channel of the primary carrier, the first transmit power can be reported to the eNB. The physical layer signaling used to carry the first maximum transmit power, including but not limited to the control information sent in the Physical Uplink Control CHannel (PUCCH).

After the first transmit power is reported to the eNB, next, in S104, the UE receives the scheduling indication information fed back by the eNB. Specifically, the scheduling indication information includes at least the transmit power control information of the eNB controlling the transmit power of the UE, the resource indication for sending the data to the UE, and the hybrid automatic repeat request. (Hybrid Automatic Repeat reQuest, HARQ) One of the process related instructions and the like.

In the embodiment of the present invention, in S105, the UE starts to send a signal in the shared spectrum according to the scheduling indication information returned by the eNB. The S105 may specifically include:

Specifically, the scheduling indication information includes transmission power control information. The transmission power control information is information that the eNB controls the UE transmission power. The UE determines the transmit power of the transmission number according to the transmit power control information. Certainly, in a specific implementation process, the UE specifically calculates and determines the transmit power of the UE according to the transmission path loss value of the downlink channel.

In order to be able to transmit a signal in the shared frequency channel, when the transmit power determined by the UE according to the transmit power control information is less than or equal to the first transmit power, the signal is transmitted in the shared spectrum channel according to the transmit power determined according to the transmit power control information; When the UE determines that the transmit power is greater than the first transmit power according to the transmit power control information, in order to prevent the received power from exceeding the reference threshold TL, the UE transmits the signal in the shared spectrum channel by using the first transmit power.

Further, in order for the eNB to facilitate the subsequent scheduling of the transmit power of the UE, after the S105, the UE also needs to report the transmit power margin to the eNB. Wherein, the power margin is the difference between the first transmit power and the transmit power.

A second aspect of the present application provides a scheduling method. Referring to FIG. 3, it is a flowchart of an eNB scheduling method. The method includes:

S201: Receive a first transmit power reported by the user equipment.

S202. Generate scheduling indication information for the user equipment based on the first transmit power.

S203: Send the scheduling indication information to the UE.

Specifically, in the embodiment of the present invention, the eNB receives the first transmit power reported by the UE in S201. The first transmit power is a transmit power that the user equipment can receive when detecting and detecting a signal in the shared spectrum channel, obtaining a detection result, and determining, according to the detection result, the user equipment sends a signal in the shared spectrum channel. For the method and implementation process for determining the first transmit power by the user equipment, refer to the foregoing embodiment, and details are not described herein again.

Next, in S201, scheduling indication information is generated based on the first transmit power, where the scheduling indication information includes at least one of transmit power control information for controlling transmission power of the UE by the eNB, an indication for transmitting data to the UE, a HARQ process indication, and the like. Kind. In the embodiment of the present invention, the transmit power control information is specifically at least one of a power control adjustment command sent by the eNB to the UE, such as a parameter P _{O_PUSCH,c} (j) for controlling a target received signal to interference and noise ratio on the eNB side. The bandwidth of the Physical Uplink Shared Channel (PUSCH) channel, the downlink path loss compensation factor α _c (j), the K _{S of the} high-level signaling configuration, and the uplink control information for each resource in the uplink shared channel. The ratio BPRE of the number of control information bits on the unit and the number of shared data bits on each resource unit is determined according to whether the uplink shared data transmission is included when the uplink control information is transmitted in the uplink shared channel.

Power adjustment cumulative factor δ _{PUSCH, c,} etc.

In the embodiment of the present invention, the eNB generates the scheduling indication information according to the first transmit power, and the eNB generates the scheduling indication information according to the maximum transmit power reported by the UE. For example, in the subframe i of the serving cell, the UE transmits the PUSCH information and does not transmit the PUCCH information, the eNB may configure the P _{O_PUSCH, c} (j), the bandwidth of the PUSCH channel, α _c (j), K _S , BPRE,

At least one parameter in δ _PUSCH,c .

Finally, the eNB sends scheduling indication information to the UE, so that the UE determines the transmission power and the transmission signal according to each information and parameter in the scheduling indication information.

In the embodiment of the present invention, the UE receives and detects the signal in the shared spectrum channel, and obtains the detection result, which specifically includes:

Or, specifically:

The power detection constant is the ninth power detection constant.

The second power detection constant, the third power detection constant, the fourth power detection constant, and the fifth power detection constant are not completely the same; the sixth power detection constant is different from the seventh power detection constant; the eighth power detection constant and the The nine power detection constants are not the same.

Further, after S203, the eNB may further receive a transmit power margin reported by the UE. The receiving eNB updates the indication information according to the first transmit power and the power headroom, and schedules the UE. For example, if the first transmit power is 23 dBm and the power margin reported by the UE is 3 dBm, the eNB can increase the transmit power in the indication information by 3 dBm.
