Description

Method for transmitting uplink signal, user equipment and network device

The present invention relates to the field of communications, and in particular, to a method, a user equipment, and a network device for transmitting an uplink signal in the field of communications. Background technique

With the rapid development of technology, people's demand for communication is getting higher and higher, and the demand for communication coverage is getting higher and higher. However, the current transmission method is difficult to meet the demanding coverage requirements, and because of the limited uplink transmission power, the uplink The reliability of transmission needs to be improved.

For the recent machine-to-machine (Machine To Machine) communication mode, it can support direct communication between machines and machines. For example, the smart meter reading service, that is, the communication module is installed on the meter, and the meter automatically sends the data in the meter to the network device at a specific time (for example, at the end of each month), thereby realizing smart meter reading. However, some business environments are relatively harsh. For example, in some European countries, electricity meters are usually installed in the basement and iron boxes for anti-theft are installed outside the meter. When the communication module in the meter needs to send data to the network equipment, due to the harsh environment. And the limitation of the transmission power of the self may result in the inability to reliably transmit the meter data. This requires the M2M communication service to have higher transmission reliability, for example, the transmission reliability of the service needs to be improved by 20 dB.

In order to solve this problem, a common method is to repeat the time to obtain the advantage of time diversity. For example, in a Long Term Evolution (LTE) system, a network device sends a control signaling to a user equipment (User Equipment, called "UE") for scheduling UE to transmit uplink data signals. For example, the physical downlink control channel (Physical Downlink Control Channel, referred to as "PDCCH") signaling, the UE transmits an uplink data signal in one uplink subframe; and for the above bad service environment, the same uplink data may be used. The signal is transmitted repeatedly several times, or the same information is transmitted in multiple uplink subframes, thereby obtaining time diversity.

Duplex, the cylinder is called "FDD") The system is still feasible, but for the Time Domain Duplex (TdD) system, the uplink signal is sent only in a partial subframe in one radio frame. This will bring more delay. For example, in order to achieve certain reliability, the uplink data signal needs to be repeated 100 times. For the FDD system, all uplink subframes can be Use, so the data delay is up to 100ms; for the TDD system, if the system's uplink and downlink subframe configuration indicates that only 1 subframe in every 5 subframes can be used for uplink transmission, the data delay will be up to 500ms. And there are also problems such as a significant reduction in reliability due to huge transmission delays.

Therefore, the current signal transmission scheme not only needs to reduce the signal transmission delay, but also needs to enhance the reliability of signal transmission. Summary of the invention

1 shows a schematic flow diagram of a method 100 of transmitting an uplink signal, which may be performed by a user equipment, such as a UE, in accordance with an embodiment of the present invention. As shown in FIG. 1, the method 100 includes:

S110. The first subframe configuration information that is sent by the network device by using the broadcast signaling, where the first subframe configuration information is used to indicate the configuration of the uplink subframe and the downlink subframe.

S120. Receive control signaling sent by the network device, where the control signaling is used to indicate that the user equipment sends an uplink signal in at least two subframes, where the at least two subframes include an uplink subframe and a downlink subframe.

S130, according to the first subframe configuration information and the control signaling, based on a first correspondence between a subcarrier and a frequency in an uplink subframe, and based on a second correspondence between a subcarrier and a frequency in a downlink subframe, Mapping the uplink data and the uplink reference signal RS carried on the subcarrier to a frequency corresponding to the subcarrier to generate a first signal;

S140. Send the first signal to the network device.

Therefore, the method for transmitting an uplink signal in the embodiment of the present invention can reduce the signal transmission delay by using time diversity to transmit the uplink signal in the uplink subframe and the downlink subframe, and can also reduce the signal transmission delay; and also pass the uplink subframe and the downlink. In the subframe, the mapping between the subcarriers and the frequency matching the subframe type is used to map, which can avoid inter-carrier interference, thereby enhancing the reliability of signal transmission and further improving the user experience.

Specifically, for example, in the LTE-TDD system, one radio frame length is 10 ms, each radio frame includes 10 subframes, each subframe length is 1 ms, and each subframe includes several symbols. The network device may send the uplink and downlink subframe configuration information to each user equipment UE in a broadcast manner, and after receiving the uplink and downlink subframe configuration information, the UE may obtain the configuration of the uplink subframe and the downlink subframe, where the uplink signal and the uplink signal are The downlink signals are transmitted in the uplink subframe and the downlink subframe, respectively.

In the LTE system, the uplink and downlink subframe configurations are, for example, as shown in Table 1, and include a total of seven configurations, in which the ratios of the number of uplink subframes and downlink subframes are different. In Table 1, D denotes a downlink subframe, U denotes an uplink subframe, and S denotes a special subframe. Some symbols in a special subframe are used for transmitting an uplink signal, and some symbols are used for transmitting a downlink signal, but in most cases, For transmitting downlink signals The number of symbols occupies the vast majority, so the S subframe can also be regarded as mainly for transmitting downlink signals, and also belongs to the category of "downlink subframes" described below.

Table 1

The network device can flexibly adjust the proportion of the number of uplink and downlink subframes according to the proportion of uplink and downlink traffic. For example, when the ratio of uplink and downlink traffic is about 3:2, the uplink and downlink subframe configuration 0 can be adopted; When the ratio of the quantity is about 1:4, the uplink and downlink subframe configuration 2 can be adopted. For the same subframe, it can only be used to transmit uplink signals or downlink signals, but not for transmitting uplink signals and downlink signals at the same time.

In the S110 of the embodiment of the present invention, the user equipment receives the first subframe configuration information that is sent by the network device by using the broadcast signaling, where the first subframe configuration information is used to reduce the signal transmission delay and the reliability of the signal transmission is improved. Indicates the configuration of the uplink subframe and the downlink subframe. For example, the first subframe configuration information is used to indicate an uplink and downlink subframe configuration number and the like as shown in Table 1.

In S120, the user equipment receives control signaling sent by the network device, where the control signaling is used to indicate that the user equipment sends an uplink signal in at least two subframes including an uplink subframe and a downlink subframe. The control signaling may indicate that the user equipment sends the uplink signal in the uplink subframe and the part of the downlink subframe, and may also indicate that the user equipment sends the uplink signal in the uplink subframe and all the downlink subframes, but the embodiment of the present invention is not limited thereto. . For example, the control signaling may also be used to indicate that the user equipment uses the uplink subframe and the downlink subframe to send an uplink signal, and the user equipment may determine, according to other rules or preset conditions, which downlink subframes are used to send the uplink signal.

In S130, the user equipment maps the signal according to the first subframe configuration information and the control signaling, respectively, in the uplink subframe and the downlink subframe by using a correspondence relationship between the subcarriers and the frequency that match the subframe type. That is, the user equipment is based on the first correspondence between the subcarrier and the frequency in the uplink subframe, And mapping the uplink data and the uplink reference signal (referred to as "RS") carried on the subcarrier to the frequency corresponding to the subcarrier based on the second correspondence between the subcarrier and the frequency in the downlink subframe. Generate the first signal.

In S140, the user equipment sends the generated first signal to the network device.

For example, the network device sends broadcast signaling to the UE, and is used to notify that the uplink and downlink subframe configuration number is

2, and the network device sends a control signaling to the UE, to indicate that the UE sends an uplink signal in 100 subframes (for example, a Physical Uplink Shared Channel ("PUSCH") in the LTE system), The UE sends an uplink signal in 10 radio frames (including 100 subframes), where, for uplink subframes with subframe numbers 2 and 7, the UE maps the signal according to the first correspondence between the subcarrier and the frequency, and For other numbered downlink subframes, the UE maps the signals according to the second correspondence between the subcarriers and the frequencies.

It should be understood that, in various embodiments of the present invention, the size of the sequence numbers of the above processes does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not be taken to the embodiments of the present invention. The implementation process constitutes any limitation.

Therefore, the method for transmitting an uplink signal according to an embodiment of the present invention can be free from the conventional

In the TDD system, the UE can only transmit the signal limit in the uplink subframe, thereby reducing the signal transmission delay and avoiding inter-carrier interference, thereby enhancing the reliability of the signal transmission and further improving the user experience.

In the existing LTE system, both the uplink transmission and the downlink transmission adopt a multi-carrier transmission method, in which the data bits are subjected to channel coding and modulation, and then inverse discrete Fourier transform (inverse Discrete Fourier Transform) The IDFT") operates to convert the signal carried on the subcarriers in the frequency domain, and finally transmits the signals carried on the subcarriers by adding a cyclic prefix (Cyclic Prefix, called "CP"). These processes are well known to those skilled in the art, and are not described here.

The process of converting the signals carried on the subcarriers in the frequency domain is also the process of placing the generated signal streams on the corresponding subcarriers (for example, placing the signals output after the i th modulation on the i+10th subcarriers) Transmitting), since the signals transmitted on different subcarriers are orthogonal to each other, the signal to be transmitted (the signal after channel coding and modulation as described above) is converted to the subcarrier carried in the frequency domain by IDFT. After the signal, the signals carried on these different subcarriers do not cause interference with each other. The receiving process of the signal is reversed, that is, after the receiver removes the CP, it needs to correspondingly obtain the corresponding subcarrier bearing on the corresponding frequency according to the mapping manner of the signal generated by the transmitter. The carried signal stream, that is, the reverse operation (for example, obtaining the i-th signal from the i+10th subcarrier), for the sake of cleaning, no further details are provided herein.

It should be understood that the signal received by the receiver is a superposition of a waveform having a different frequency and a DC level. Since the energy of the DC level is high, if the frequency corresponding to the DC level is used to transmit the useful signal, the useful signal is interfered by the DC level. Very large, so the frequency corresponding to the DC level is usually not used to transmit the useful signal, which is the most intermediate frequency of the system bandwidth, hereinafter referred to as DC (Direct Current, referred to as "DC") frequency. Also, in order to minimize the influence of the DC level on other signals, the frequency of the subcarrier closest to the DC frequency should be as large as possible with the DC frequency.

The corresponding relationship between the subcarriers and the frequency of the uplink and downlink transmission is different, because in the uplink subframe, the UE transmit signal is limited by the peak-to-average power ratio (the peak is called "PAPR"). For high requirements, the UE may use the Single-Carrier Frequency-Division Multiple Access (SC-FDMA) method to transmit uplink signals, and the signals are required to be continuous in the frequency domain, that is, the signals must be Mapping to subcarriers that are contiguous in frequency; and in the downlink subframe, the network device transmits signals that are not limited by the PAPR, the network device may adopt orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, referred to as "OFDMA" The way of transmitting the downlink signal is not required to be continuous in the frequency domain.

Based on the above considerations, in the LTE-TDD system in which both the uplink and downlink system bandwidths are the same, the corresponding relationship between the uplink and downlink subcarriers and the frequency is as shown in FIG. 2, where the most intermediate frequency of the system bandwidth (ie, the DC frequency). For f_0, the subcarrier spacing is A f; for the uplink, the subcarrier frequencies are f_0±l/2Af, f_0±3/2Af, f_0±5/2Af, and for downlink, the subcarrier frequencies are respectively F_0±Af, f_0±2Af, f_0±3Af, .... Therefore, the first correspondence between the subcarriers of the uplink signal and the frequency is such that the frequency of the subcarriers of all the uplink signals is separated from the middlemost frequency of the system bandwidth by an odd multiple of 1/2 subcarrier width; and the subcarriers of the downlink signal are The second correspondence of frequencies is such that the frequency of the subcarriers of all downlink signals is separated from the most intermediate frequency of the system bandwidth by an integer multiple of one subcarrier width, wherein the downlink transmitted signal avoids the DC frequency. Thus, the mapping manner of the uplink subcarriers and the mapping manner of the downlink subcarriers have an interlace of half subcarriers, and the frequencies to which they are mapped are different. The uplink or downlink transmission scheduled by the network device for the UE is a physical resource block ("PRB") pair (PRB pair), and one PRB pair includes 12 subcarriers in the frequency domain. The field includes the length of one subframe, as shown in Figure 2.

Since the corresponding relationship between the uplink and downlink subcarriers and the frequency is different, the frequency of the uplink and downlink subcarriers is made. The rate is misplaced, which causes: If the same frequency band is used to transmit the uplink and downlink signals, the inter-carrier interference between the uplink and downlink signals is serious, and even if the uplink signal and the downlink signal use PRB pairs with far-frequency frequency intervals, As long as both signals belong to the same frequency band, the interference still exists.

Based on the above considerations, in the embodiment of the present invention, the UE maps the content carried on the subcarrier to the frequency corresponding to the subcarrier based on the first correspondence between the subcarrier and the frequency in the uplink subframe, as shown in FIG. The network device can allocate different frequency resources for UE1 and UE2, for example, different PRB pairs. Since they use the first correspondence between the same subcarrier and frequency, UE1 and UE2 do not interfere with each other.

In the downlink subframe, the UE maps the content carried on the RE to the subcarrier based on the second correspondence between the subcarrier and the frequency, so as to avoid interference of the uplink signal sent by the UE on the downlink signal received by other UEs. As shown in FIG. 3, the network device allocates different frequency resources for the uplink transmission of the UE1 and the downlink transmission of the UE3. Since they use the second corresponding relationship between the subcarrier and the frequency, the signal sent by the UE1 does not receive the signal received by the UE3. Inter-carrier interference. In the embodiment of the present invention, only the behavior of the UE1 that uses the method for transmitting an uplink signal according to an embodiment of the present invention needs to be changed to solve the technical problem, and the signal transmissions of the UE2 and the UE3 are not affected, and they are transmitted or received. The signal is also not interfered by the signal transmitted by UE1, so the method according to an embodiment of the invention has better backward compatibility.

In the embodiment of the present invention, optionally, as shown in FIG. 4, before the generating the first signal, the method 100 further includes:

S150, based on an uplink reference signal (reference signal, referred to as "RS") pattern in the uplink subframe, and based on the downlink RS pattern in the downlink subframe, respectively, the resource unit corresponding to the uplink RS pattern and the downlink RS pattern On the symbol of the (Resource Element, the tube is called "RE"), the uplink RS is mapped to the subcarrier corresponding to the RE, where one RE corresponds to one symbol of the time domain and one subcarrier of the frequency domain.

That is, the UE determines the RE corresponding to the uplink RS according to the uplink RS pattern in the uplink subframe, so that the RE corresponding to the uplink data can also be determined correspondingly, and according to the uplink RS and the RE corresponding to the data, The uplink corresponding RS and the data are respectively mapped to the subcarriers corresponding to the REs. In the downlink subframe, the UE determines the RE corresponding to the uplink RS according to the downlink RS pattern, so that the RE corresponding to the uplink data can also be determined correspondingly. According to the RE corresponding to the uplink RS and the data, the uplink RS and the data are respectively mapped to the subcarriers corresponding to the REs; wherein, one RE corresponds to one symbol of the time domain and one subcarrier of the frequency domain. .

For example, Figure 5 shows the uplink RS pattern and the downlink RS pattern, respectively, where RS is used by the receiver for channel estimation, i.e., the receiver first decodes the data signal based on the received RS and then decodes the data signal. In the embodiment of the present invention, for example, the UE maps the uplink RS and the uplink data to the corresponding subcarriers in the uplink subframe according to the uplink RS pattern shown in FIG. 5, and is based on FIG. 5 in the downlink subframe. The downlink RS pattern shown maps the uplink RS and uplink data to corresponding subcarriers. Therefore, the network device can perform multi-user multiple input multiple output (CU-MIMO) scheduling on the UE and the other UEs using the method of the present invention to improve transmission efficiency, where MU-MIMO means that the network device allocates the same PRB pair to multiple UEs. For example, in the uplink subframe shown in FIG. 3, the network device may allocate the same PRB pair to UE1 and UE2, or in the downlink shown in FIG. In the subframe, the uplink signal is sent for UE1 and the downlink signal is received by UE3 to allocate the same PRB pair.

It should be understood that MU-MIMO scheduling requires that these UEs use the same RS and data mapping scheme and allocate mutually orthogonal RS resources to ensure that these RSs have no interference with each other. It should also be understood that the MU-MIMO technology is well known to those skilled in the art and is not mentioned here.

In the embodiment of the present invention, optionally, sending the first signal to the network device includes: transmitting the first signal in a downlink subframe by using a preset RS resource or using the RS resource notified by the network device The upstream RS included.

Specifically, for example, in an LTE system, when a UE sends an uplink RS or a network device sends a downlink RS, some or all orthogonal RS resources in all orthogonal RS resources are generally used, where the orthogonal manner includes time division, frequency division, and / or code points are orthogonal. For example, the LTE system includes eight downlink orthogonal RS resources, and the downlink orthogonal RS resources are orthogonalized by frequency division and/or code division. If the network device schedules four layers of transmission, 4 of them are used. The orthogonal resources are used to send the downlink RS. In the embodiment of the present invention, the UE sends an uplink signal in a downlink subframe, and also sends an uplink RS. Preferably, the uplink RS sent by the UE in the downlink subframe uses the reserved orthogonal resource. For example, when one orthogonal resource is reserved in the downlink subframe, when the UE adopting the method of the present invention sends an uplink signal in the downlink subframe, the reserved orthogonal resource is used to send the RS, where the reservation is performed. Orthogonal capital The source may be fixedly stored on the UE and the network device side; or may be configured by the network device and send signaling to the UE to notify.

In the embodiment of the present invention, in order to ensure the performance of the MU-MIMO, the multiple access modes used by the UE in different ports are different. Specifically, the first signal is sent to the network device, where the first multiple access mode is used in the uplink subframe, and the second multiple access mode is used in the downlink subframe, and the first signal is sent. The first multiple access mode is different from the second multiple access mode.

Optionally, the first multiple access mode is a single carrier frequency division multiple access SC-FDMA mode, and the second multiple access mode is an orthogonal frequency division multiple access OFDMA mode. It should be understood that the embodiment of the present invention is only described by using the SC-FDMA mode and the OFDMA mode as an example. However, the embodiment of the present invention is not limited thereto, and the user equipment may also use other multiple access modes to transmit the first signal.

In the embodiment of the present invention, optionally, sending the first signal to the network device includes: adopting a first physical resource block PRB pair in an uplink subframe, and adopting a second PRB pair in the downlink subframe, sending The first signal, wherein the first PRB pair is different from the second PRB pair.

Specifically, the PRB pair number used by the UE to transmit the uplink signal in the uplink subframe and the downlink subframe is different. The UE transmits the same control signaling sent by the network device, so that the UE can use the PRB pair with less interference to the important uplink signal when the uplink subframe sends the uplink signal. For example, a physical uplink control channel (Physical Uplink Control Channel, referred to as "PUCCH") signaling, etc., and a PRB pair that has less interference to important downlink signals, such as a broadcast signal or a synchronization signal, is used when transmitting the uplink signal in the downlink subframe. Etc., to minimize interference with uplink and downlink signals.

For example, if the system bandwidth corresponds to 50 PRB pairs, in the uplink subframe, the PRB pairs numbered 0 and 49 are usually used to transmit PUCCH signaling, and the network device can schedule the PRB pair numbered 22-25 for the UE. For transmitting uplink signals, in the downlink subframe, the PRB pairs numbered 22~27 are usually used to transmit physical broadcast channels (Physical Broadcast Channels, called "PBCH") signaling, in order to avoid these If the PRB pair causes interference, the network device may schedule the PRB pair with the number 28~31 for the UE to transmit the uplink signal.

Further, in the embodiment of the present invention, optionally, as shown in FIG. 6, the method 100 further includes:

S160. Receive PRB pair adjustment information sent by the network device.

The sending the first signal to the network device includes: S141: Send the first signal according to the PRB to the adjustment information in the downlink subframe.

In the embodiment of the present invention, the PRB pair adjustment information may be used to indicate an adjustment amount between the number of the first PRB pair and the second PRB pair, and may also be used to indicate that the first signal is sent in the downlink subframe. The number of the second PRB pair, the embodiment of the present invention is not limited thereto.

Specifically, the network device may send PRB pair adjustment information to the UE for controlling the UE to send the PRB pair of the uplink signal in the uplink subframe and the downlink subframe. For example, the network device sends control signaling to the UE, instructing the UE to transmit the uplink data signal in the PRB pair with the number 22~25, and indicates to the UE that the PRB pair adjustment amount is 6 PRB pairs, then in the uplink subframe, the UE The uplink signal is transmitted by the PRB pair numbered 22~25. In the downlink subframe, the UE transmits the uplink signal by using the PRB pair numbered 28~31 (22+6~25+6).

In the embodiment of the present invention, optionally, as shown in FIG. 7, the method 100 further includes:

S170. Receive S subframe structure information sent by the network device.

The sending the first signal to the network device includes:

S142: Send the first signal in a downlink symbol indicated by the S subframe structure information.

Specifically, the user equipment may receive the S subframe structure information sent by the network device. In the S subframe, the UE sends the first information in the indicated downlink symbol according to the received S subframe structure information. For example, a subframe includes 14 symbols, and the network device sends S subframe structure information to the UE, indicating that the downlink period in the S subframe occupies the first nine symbols of the S subframe, and the uplink period occupies the last symbol of the subframe. The middle part does not send any signal to ensure cell coverage. After receiving the S subframe structure information, the UE sends an uplink signal on the first nine symbols in the S subframe, which is convenient.

The UE sends the downlink signal to maintain the same structure, and ensures that the uplink signal sent by the UE in the S subframe without using the UE of the present invention does not interfere with other signals, and does not affect the coverage of the cell.

Optionally, in the embodiment of the present invention, sending the first signal to the network device includes: sending, in an uplink subframe and/or a downlink subframe, the first signal by using six intermediate PRB pairs. Send between 6 PRB pairs. The LTE system can support different frequency bands, and the frequency bands corresponding to different sizes of bandwidths centered on the same frequency point include the middle 6 PRB pairs. Therefore, if the uplink transmissions according to the embodiment of the present invention are in the 6 When the PRB is performed on the uplink, the implementation scheme is compared, and the operation can be performed in different frequency bands, which is convenient for reducing the cost of the UE and flexibly supporting the bandwidth. Optionally, in the embodiment of the present invention, the sending the first signal to the network device includes: transmitting the first signal by using a first time-frequency resource in a downlink subframe, where the first time-frequency resource and the The second time-frequency resource used by the network device to transmit the broadcast signal or the synchronization signal is different.

Specifically, when the UE sends the uplink signal in the downlink subframe, the UE avoids the resource of the broadcast signal and the synchronization signal, for example, the UE using the present invention does not use the PBCH and the synchronization channel (Synchronization Channel) in the LTE system. The time-frequency resource corresponding to "SCH" is used to transmit the uplink signal, thereby preventing the uplink signal from interfering with the broadcast signal or the synchronization signal.

FIG. 8 shows still another schematic flow chart of a method 100 of transmitting an uplink signal in accordance with an embodiment of the present invention. As shown in FIG. 8, the method 100 further includes:

S180: Receive second subframe configuration information that is sent by the network device, where a part of the uplink subframe that is indicated by the second subframe configuration information corresponds to a part of the downlink subframe that is indicated by the first subframe configuration information, where the first generation is generated. Signals, including:

S131, in the part of the uplink subframe indicated by the second subframe configuration information, by mapping the uplink data and the uplink RS carried on the subcarrier to the subcarrier corresponding to the second correspondence between the subcarrier and the frequency. The first signal is generated on the frequency.

That is, the user equipment generates the first signal by mapping the uplink data and the uplink RS carried on the subcarrier to the frequency corresponding to the subcarrier based on the second correspondence between the subcarrier and the frequency in the first subframe. The first subframe is indicated as an uplink subframe in the second subframe configuration information, but is indicated as a downlink subframe in the first subframe configuration information.

It should be understood that, the UE generating the first signal further includes: in the uplink subframe indicated by the first subframe configuration information, by using the first correspondence between the subcarrier and the frequency, by using uplink data and uplink RS carried on the subcarrier The first signal is generated on a frequency mapped to the subcarrier.

Specifically, in the embodiment of the present invention, the user equipment receives the second subframe configuration information that is sent by the network device, where the second subframe configuration information is used to indicate the configuration of the uplink subframe, or is used to indicate the uplink subframe and the downlink. The configuration of the subframe; the UE sends an uplink signal in a part of the uplink subframe indicated by the second subframe configuration information according to the second subframe configuration information, where the second subframe configuration information refers to The partial subframe in the indicated uplink subframe corresponds to a part of the downlink subframe indicated by the first subframe configuration information broadcast by the network device to the UE.

For example, the second subframe configuration information and the first subframe configuration information broadcast by the network device correspond to the same subframe configuration table, for example, the uplink and downlink subframe configuration table shown in Table 1. That is, the network device notifies the UE that the uplink and downlink subframes are configured as the configuration 2 in Table 1, and sends signaling to the UE, and notifies the uplink and downlink subframe configuration with the number 0 in the second subframe configuration indication table 1 The UE sends an uplink signal in the uplink subframe (the subframes numbered 2, 3, 4, 7, 8, 9) corresponding to the uplink and downlink subframe configuration with the number 0, where the uplink is broadcast for the network device. In the row subframe configuration (upstream and downlink subframe configuration numbered 2), the subframes numbered 3, 4, 8, and 9 are downlink subframes, and the UE is in subframes numbered 3, 4, 8, and 9. The uplink signal is sent by using the foregoing method of the present invention, for example, using the second correspondence between the subcarrier and the frequency to transmit the uplink signal, or mapping the uplink RS to the RE corresponding to the downlink RS pattern based on the downlink RS pattern, and the like. It should be understood that the UE also sends an uplink signal in an uplink subframe in which the network device broadcasts the notification.

For example, the network device does not send the second uplink and downlink subframe configuration to the UE, but only sends the second uplink subframe configuration to the UE, for example, notifying the UE in the subframes numbered 2, 3, 4, 7, 8, and 9. Sending the uplink signal can also achieve the same technical effect. For example, the network device may send the second subframe ratio to the UE in a bitmap manner. For example, 1 indicates a downlink subframe, and 0 indicates an uplink subframe, and the network device may send 1100011000 to the UE, which also achieves the same technical effect.

In the embodiment of the present invention, receiving the second subframe configuration information that is sent by the network device includes: receiving the second subframe configuration information that is sent by the network device in a bitmap mode or a unicast manner. Optionally, the second subframe configuration information and the first subframe configuration information correspond to the same uplink and downlink subframe configuration table.

In the embodiment of the present invention, the manner in which the network device sends the second subframe configuration information to the UE is preferably a unicast mode. Therefore, the present invention may be implemented only for the UE adopting the method of the embodiment of the present invention, but not for other UEs. The invention is implemented to reduce complexity and flexibility.

FIG. 9 shows still another schematic flow chart of a method 100 of transmitting an uplink signal in accordance with an embodiment of the present invention. As shown in FIG. 9, the method 100 further includes:

S190. Receive power adjustment information sent by the network device.

The sending the first signal to the network device includes:

S143. Send the first signal according to the power adjustment information in a downlink subframe.

In this embodiment of the present invention, the power adjustment information may be used to indicate that only the user equipment is under The power value used for transmitting the first signal in the downlink subframe may also be used to indicate the power difference used by the user equipment to send the first signal in the uplink subframe and the downlink subframe, but the embodiment of the present invention is not limited thereto. .

Specifically, the UE receives the power adjustment information sent by the network device, and after receiving the UE, the UE adjusts the transmission power of the first signal in the downlink subframe according to the power adjustment information. For example, the network device sends power adjustment information to the UE, indicating that the transmission power deviation between the downlink subframe and the uplink subframe of the UE is A dB. If the transmission power of the UE in the uplink subframe is P_u, the UE transmits in the downlink subframe. The power is P_d, where P_d = P_u + A. Thereby, it is possible to facilitate matching the transmission power of the UE with the interference or noise environment of the uplink subframe and the downlink subframe.

With reference to FIG. 1 to FIG. 9 , a method for transmitting an uplink signal according to an embodiment of the present invention is described in detail from the perspective of a user equipment. Hereinafter, a method according to an embodiment of the present invention will be described from the perspective of a network device with reference to FIG. 10 to FIG. The method of transmitting the uplink signal.

It should be understood that the interaction between the UE and the network device described in the network device side and related features, functions, and the like correspond to the description on the user equipment side, and are not described herein again.

Figure 10 illustrates a method 200 of transmitting an uplink signal, which may be performed by a network device, such as a base station or other network device, in accordance with an embodiment of the present invention. As shown in FIG. 10, the method 200 includes:

S210, the first subframe configuration information is sent to the user equipment by using the broadcast signaling, where the first subframe configuration information is used to indicate the configuration of the uplink subframe and the downlink subframe.

S220: Send control signaling to the user equipment, where the control signaling is used to indicate that the user equipment sends an uplink signal in at least two subframes, where the at least two subframes include an uplink subframe and a downlink subframe. S230. Receive the user equipment. And transmitting, by the user equipment, the first signal based on the subcarrier and the frequency in the uplink subframe according to the first subframe configuration information and the control signaling The corresponding relationship is generated by mapping the uplink data and the uplink reference signal RS carried on the subcarrier to the frequency corresponding to the subcarrier based on the second correspondence between the subcarrier and the frequency in the downlink subframe.

Specifically, in the embodiment of the present invention, the network device sends the first subframe configuration information to the user equipment by using the broadcast signaling, and is used to indicate the configuration of the uplink subframe and the downlink subframe, where the first subframe configuration information is used, for example.
