The scenario of the embodiment of the present invention is described below by way of example, but the present invention is not limited thereto.

1 is a schematic diagram of a communication system according to an embodiment of the present invention. The terminal device and the network device are exemplarily illustrated. As shown in FIG. 1, the communication system 100 may include a network device 101 and a terminal device 102. For the sake of simplicity, FIG. 1 is only described by taking one terminal device and one network device as an example, but the embodiment of the present invention is not limited thereto.

In the embodiment of the present invention, an existing service or a service that can be implemented in the future can be performed between the network device 101 and the terminal device 102. For example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and high reliability low latency communication (URLLC, Ultra-Reliable and Low). -Latency Communication), and so on.

The embodiment of the present invention will be described below by taking the NR system as an example; however, the present invention is not limited thereto, and can be applied to any system or scenario in which similar problems exist. Furthermore, the receiving device for controlling information according to the present invention may be a terminal device, and the transmitting device for controlling the information may be a network device, but the present invention is not limited thereto.

The URLLC service has extremely high requirements for transmission reliability and transmission delay. For example, it may be required to start from the buffer of the layer 2/layer 3 of the data packet to the sending device, until the data packet is correctly demodulated and stored in the layer 2/layer 3 buffer of the receiving device, and the transmission delay cannot exceed 1 ms. . At the same time, the transmission needs to meet the correct rate of 99.999%, that is, only one transmission failure (timeout or transmission error) can occur for every 100,000 packets transmitted.

At present, it is widely discussed in the progress of the standard how to ensure that the physical layer transmission reliability of the URLLC packet itself meets 99.999% within 1 ms delay. However, in a mobile communication system, the physical layer transmission itself is only a link of transmission. In addition, the network device may send configuration information for setting physical layer transmission related parameters and/or modes to the terminal device before the physical layer transmission; and enable or activate the URLLC physical layer transmission. After the establishment, the network device may also send reconfiguration information to the terminal device, and the reconfiguration information may be used to change/replace, increase or decrease physical layer transmission related parameters and/or modes, and the like.

An error occurs in the configuration or reconfiguration information of the physical layer transmission, which may cause an error in the physical layer transmission of the URLLC packet itself, thereby threatening the transmission reliability of the URLLC data. For example, in a time domain unit, the network device and the terminal device may have inconsistent understanding of adopting a new configuration or an old configuration in the time domain unit. Due to this inconsistency, the URLLC packets transmitted in the time domain unit will have a large probability of error and the retransmission of the physical layer cannot reduce the probability of such errors, because physical layer retransmission can be overcome by channel changes. An error caused by unreliable transmission, which is caused by a mismatch between the sending and receiving methods themselves.

How to ensure the transmission reliability of the configuration information related to the physical layer transmission configuration, and avoid the failure of the physical layer transmission of the URLLC data due to the reception and/or transmission error of the configuration information becomes an urgent problem to be solved. For example, in the transmission process of the high layer signaling, the reliability of the response signal (ACK/NACK) corresponding to the physical data channel carrying the high layer signaling is a weak link in the entire transmission process.

For example, the network device sends configuration information to the terminal device, the terminal device fails to correctly receive the data channel and feeds back the NACK signal to the network device, but the NACK signal is incorrectly decoded into an ACK on the network device side. In this case, the terminal device waits for the retransmission of the data channel while continuing to use the old configuration, and the network device assumes that the terminal device successfully receives the data channel and correctly interprets the high layer signaling carried therein, and then after the appointed time The configuration is changed to a new configuration. So far, after the appointment time, the network device and the terminal device have different understandings of the physical layer transmission configuration.

Example 1

In order to solve at least one of the above problems, an embodiment of the present invention provides a method for receiving control information. FIG. 2 is a schematic diagram of a method for receiving control information according to an embodiment of the present invention, showing a situation on the terminal device side. As shown in Figure 2, the method includes:

Step 202: The terminal device receives the control information sent by the network device, where the control information is used to indicate that the terminal device performs the receiving or sending of the sample of the data, where the control information is further used to indicate that the response signal corresponding to the data includes At least two samples.

In this embodiment, the response signal corresponding to the data may be a response signal for indicating that the data reception is correct and/or incorrect. For example, an acknowledgment (ACK) signal can be used to confirm that the data is received correctly, and a non-acknowledgement (NACK) signal can be used to confirm that the data was received incorrectly. The downlink control information or the uplink control information, which may be a downlink data channel or an uplink data channel, may be used for carrying the response signal that the indication data is received correctly and/or incorrectly. The response signal corresponding to the data may be used only to confirm that the reception of the data is completed or the transmission is completed.

It should be noted that the object sent and received by the terminal device is not necessarily a network device, but may also be other terminal devices. The embodiment of the present invention is described by taking the communication between the terminal device and the network device as an example, but is not limited thereto.

In an embodiment, the control information is used to indicate that the terminal device performs transmission of data samples, and the response signal with the data response may be downlink control information, where the downlink control information may be the same as the data by scheduling. The new data of the HARQ process number is used to indicate that the data transmission of the terminal device is completed, or to indicate that the data of the terminal device is completely transmitted at the physical layer.

For example, the network device may reach a consistent understanding of the success or failure of the transmission by the terminal device by using a pre-configured or pre-agreed method to “complete the transmission of the data at the physical layer this time”. This indicates that the transmission of the data is correct or incorrect by indicating the completion of the transmission.

For example, the network device may reach a consistent understanding of the operations performed by the terminal device after the “transmission of the data at the physical layer” is completed by the pre-configured or pre-agreed method. In other words, by a pre-configured or pre-agreed method, the terminal device knows the operations that need to be performed after the “data is transmitted at the physical layer this time”, for example, clearing the uplink memory or the like.

Furthermore, the response signal corresponding to the data comprises at least two samples, for example, the response signal corresponding to the data comprises M samples, wherein M is a positive integer and M is greater than or equal to 2. The sample of the data is P, wherein P is a positive integer, P is greater than or equal to 1, and P is less than M. In one example, P is 1 and M is greater than or equal to 2. In this case, the data channel transmits only one sample, and the response signal transmitted with it responds with M samples, in order to improve the transmission reliability of the response signal.

In another example, M is an odd number. The receiving device of the response signal can determine the majority of the M sample detection results as the final detection result. When the possible outcomes are two, such as ACK or NACK, or, for example, ACK or no, M is an odd number to avoid the case where the number of samples of the two results is equal, thereby increasing the reliability of the detection. For example, M is greater than or equal to 3, P is greater than or equal to 1, and P is less than M.

In this embodiment, when the control information indicates that the terminal device receives the data, the receiving device of the response signal may be a network device. When the control information indicates that the terminal device transmits data, the receiving device of the response signal may be the terminal device; the present invention is not limited thereto.

In this embodiment, the data is a bearer object of the physical layer data channel, and may be data of a higer layer, or may be high-level control signaling and/or control information. As described above, the present invention is directed to solving the reliability of the terminal device and the network device for correctly transmitting the data, and/or whether the data is transmitted consistently and correctly. The present invention is applicable to a scenario in which the terminal device and the network device have the correct and consistent understanding of whether the data is correctly transmitted and/or whether the data is transmitted or not, which helps ensure the reliability of subsequent data transmission. Or, to help ensure the reliability of other subsequent control processes.

Therefore, the gist of the present invention is different from the prior art which is solely dedicated to enhancing the reliability of data transmission. For example, existing enhanced coverage NBIoT transmission technology. In order to enhance the coverage of 20 dB, the NBIoT technology simultaneously enhances the reliability of the control channel for scheduling the data channel, the data channel carrying the data, and the control information for carrying the corresponding information with the data channel response. One method in the NBIoT technology is that all of the above three channels are transmitted over multiple repetitions in the time domain, overcoming transmission failures caused by 20 dB of signal attenuation by simple energy accumulation.

In the present invention, the reliability of the data (for example, high-level data/signaling) may be ensured by an existing physical layer retransmission or a radio link layer retransmission mechanism, or by other transmission methods, and the present invention does not This is limited. The problem solved by the present invention is that the response signal corresponding to the data is a physical layer response signal, usually one transmission. The "one-time transmission" means, for example, that there is no response signal for the response signal, and there is no retransmission mechanism for the response signal.

Therefore, in the implementation method of the present invention, in order to increase the transmission reliability of the response signal, in the physical layer data channel scheduling transmission, M samples of the response signal corresponding to the physical layer data channel are transmitted to ensure the network device and the terminal. The device has a correct and consistent understanding of the response signal, thereby achieving one of the objects of the present invention, namely, highly reliable implementation of whether the terminal device and the network device correctly transmit the data, and/or the data Whether the transmission is complete and consistent.

In step 202, the sample of the data refers, for example, to a sample of a physical layer transport block in which the data resides. In one example, the sample of the transport block, for example, refers to the transport block after being processed, for example, after dividing the coded block and or channel coding, according to the indication of the control information or according to a pre-agreed in a soft memory (for example, called Some encoded bits read in Soft buffer). The encoded bit is read in the soft memory, and the starting position of the reading can be indicated by the control information, or can be agreed in advance. The number of coded bits included in a sample is related to the size of the time-frequency resource carrying the sample and/or the constellation modulation used by the sample, the multi-antenna transmission mode, and the like. The coded bits contained in one sample and the other may be the same or different.

In this embodiment, the response signal corresponding to the data includes at least two samples, wherein the at least two samples may be obtained by at least one of the following methods:

In one embodiment, the response signal is repeated at least twice, and then the signal after the repeated signal is subjected to channel coding and/or sequence mapping to obtain a signal including at least two samples;

In one embodiment, the response signal is a signal generated after channel coding and/or sequence mapping, and the generated signal is repeated at least once, and the generated signal corresponds to one sample, and one sample is repeated at a time, thereby obtaining at least one sample. Signal of two samples;

In one embodiment, the response signal is a signal including at least two samples generated after channel coding, and at least one of the at least two samples includes a channel coded bit and a channel included in another sample. Different coding bits;

In one embodiment, the at least two samples are mapped to the sequence generated by the response signal, the sequence of the response signal mapping differs in at least one of the at least two samples from another sequence, or The sth element of at least one sequence is different from the sth element of another sequence, the element index of the sequence is from 1 to S, and S and S are positive integers, and s ranges from 1 to S. The elements may be different in value or different in phase and/or amplitude of the elements.

Each of the above embodiments may be used alone or in combination. For example, a method of generating at least one of the at least two samples may be different from a method of generating another sample. In addition, in step 202, the control information is further configured to indicate that the response signal corresponding to the data includes at least two samples.

In one embodiment, the control information can be indicated in an implicit manner. For example, the control information passes through a format of its control information, or a control resource set (CORSET, control resource set) in which the control information is located, or a search space in which the control information is located. Alternatively, the location of the monitor information in the time domain or the like of the control information indicates that the response signal corresponding to the data includes at least two samples.

In an embodiment, the control information may also indicate, in an explicit manner, that the response signal corresponding to the data includes at least two samples. For example, the control information includes first indication information, and the first indication information may be used to indicate a number of samples (ie, a value of M) included in the response signal corresponding to the data. For another example, the first indication information may be used to indicate that at least two samples are included, and the value of M is indicated to the terminal device by using other control information or control signaling, or the value of M is a communication standard specification. .

In an example, when the first indication information indicates that the number of samples is 0, the response signal corresponding to the data is sent in a first mode (for example, a normal mode). When the first indication information indicates that the number of samples is greater than or equal to 2, the corresponding response signal of the data is sent in a second mode (for example, a multi-sample mode), or the corresponding response signal of the data includes at least two sample.

In one example, the control information of the first format is used to indicate that the response signal corresponding to the data includes one sample (or two samples), and the control information of the second format is used to indicate that the response signal corresponding to the data includes At least two samples (or at least three samples). For example, the first format control includes first indication information, and the control information of the second format does not include first indication information. The terminal device determines, according to the format of the control information (and/or the first indication information), the number of samples included in the response signal corresponding to the data.

In one example, the control information detected by the terminal device in the first CORESET (and/or search space) indicates that the response signal corresponding to the data includes one sample (or two samples), and the terminal device is The control information detected in the second CORESET (and/or search space) indicates that the response signal corresponding to the data contains one sample (or two samples). For example, the first format control includes first indication information, and the control information of the second format does not include first indication information. The terminal device determines, according to the CORESET (and/or the search space, and/or the first indication information) of the control information, the number of samples included in the response signal corresponding to the data.

In one example, the control information includes indication information indicating the value of M, but does not include indication information for indicating the number of samples of the data. Or, in this example, the sample of the data is one (or, the data is sent without repeating), and the response signal of the data response contains at least two samples (or, the response signal is sent in a duplicate manner) And the sample of the response signal is indicated by the control information.

Next, the transmission/reception mode of the response signal including M samples will be described. The sending/receiving manner of the M-samples corresponding to the data response may be configured by the network device for the terminal device, or may be agreed by the communication standard specification, or may be preset in the network device and/or the terminal device.

In an embodiment, the method of transmitting/receiving the M-samples with the data response is configured by the network device for the terminal device. As shown in FIG. 2, the method of the embodiment of the present invention may further include:

Step 201: The terminal device receives the high layer signaling sent by the network device, where the high layer signaling is used to indicate at least one of the following information: the number of the at least two samples, and the at least two samples The mode of transmission, the manner in which the at least two samples are received.

For example, the high layer signaling may be Radio Resource Control (RRC) signaling (or information), or Media Access Control (MAC) signaling (or information). It should be noted that the above step 201 is optional, that is, the embodiment of the present invention can also be implemented without step 201.

In this embodiment, the sending or receiving manner of the at least two samples may be one of the following manners, or a combination of two or more of the following manners:

In one embodiment, the M samples of the response signal are transmitted in N time domain units; wherein M and N are positive integers and M is greater than or equal to N. The time domain unit may be a frame, a subframe, a time slot, or a time domain symbol.

The high layer signaling may be used to configure the position of the N time domain units on the time axis, or the distribution pattern of the N time domain units on the time axis. The position or distribution pattern on the time axis may be indicated by a bitmap, or the position or pattern may be agreed in advance and numbered, and the specific position or pattern may be indicated by the index.

For example, M samples of the response signal are transmitted on N time domain units. The positions of the N time domain units on the time axis may be continuous or discontinuous, or a part of them may be continuous while another part is discontinuous. Thus, by utilizing the time diversity of the M samples in N time-domain unit transmissions, additional gain can be obtained, thereby improving the quality of the received signal or increasing the probability that the received signal is correctly received.

In one embodiment, the M samples of the response signal are transmitted in M frequency domain resources in one time domain unit.

The high-level signal may be used to configure a location of the M frequency-domain resources in the frequency domain, or a distribution pattern of the M frequency-domain resources. The position or distribution pattern in the frequency domain may be indicated by a bitmap form, or the position or pattern may be agreed in advance and numbered, and the specific position or pattern may be indicated by the index.

For example, M frequency domain resources on the same time domain unit transmit M samples of the response signal. M frequency domain resources may be continuous or discontinuous in the frequency domain. Thus, the frequency gain of the M samples transmitted in the M frequency domain resources is used to obtain additional gain, thereby improving the quality of the received signal or the probability of being correctly received.

In an embodiment, the M samples of the response signal are transmitted in M time-frequency resources, and at least two of the M time-frequency resources are located in different time domain units.

The high layer signaling may be used to configure the location of the M time-frequency resources, or the distribution pattern of the M time-frequency resources. The position or distribution pattern may be indicated by a form of a bitmap, or a position or a pattern may be agreed in advance and numbered, and a specific position or pattern may be indicated by an index.

For example, M samples of the response signal are transmitted at M time-frequency resources, wherein at least two time-frequency resources are located in different time domain units. Thereby, the extra gain is obtained by using the time domain diversity and the frequency domain diversity of the M samples transmitted in the M time-frequency resources, thereby improving the quality of the received signal or the probability of being correctly received.

In one embodiment, the M samples of the response signal are transmitted on N carriers or a Bandwidth Part (BWP); wherein N is a positive integer and M is greater than or equal to N.

The high layer signaling may be used to indicate N carriers/BWPs, which may be indicated by an index of a carrier/BWP or a center frequency point or the like. Further optionally, the high layer signaling may further indicate at least one of a format, a mode, and a time-frequency resource location adopted by the response signal on the N carriers/BWPs.

For example, M samples of one ACK/NACK signal are transmitted on N carriers/BWP. Thereby, the frequency diversity gain of the N carriers/BWP and the repetition gain between the plurality of links can be obtained, thereby improving the quality of the received signal or the probability of being correctly received.

In one embodiment, the M samples of the response signal are transmitted on N transmit beams; wherein N is a positive integer and M is greater than or equal to N.

The high layer signaling may be used to indicate an index or an equivalent direction of the N transmit beams, or the high layer signaling is used to indicate to the terminal device in the configured N greater than or equal to N transmit beams. N.

For example, M samples of the response signal are transmitted using N transmit beams (beams, or may also be referred to as lobes) to obtain spatial diversity gains, thereby increasing the quality of the received signal or the probability of being correctly received.

In one embodiment, the M samples of the response signal are transmitted on N antennas; wherein N is a positive integer and M is greater than or equal to N. The antenna may be an actual physical antenna or an equivalent antenna port.

The high layer signaling may be used to indicate an index or a port of the antenna, or the high layer signaling is used to indicate to the terminal device in an actual antenna (or a configured antenna port) greater than or equal to N N.

For example, M samples of the response signal are transmitted using N antennas, wherein at least one of the samples uses a number of transmit antennas less than N. Thereby, the spatial diversity gain is obtained, thereby improving the quality of the received signal or the probability of being correctly received.

In an embodiment, at least one of the M samples of the response signal is sent in a Physical Uplink Control Channel (PUCCH), and at least another sample is in a Physical Uplink Shared Channel (PUSCH). send. The time domain and frequency domain diversity gains are thus obtained, thereby improving the quality of the received signal or the probability of being correctly received.

The high layer signaling may be used to configure at least one of: transmitting on the PUSCH; time-frequency resources where the PUCCH is located; format of the PUCCH, and the like.

In one embodiment, the transmission signal of at least one of the M samples of the response signal is a modulation symbol, and the transmission signal of at least another sample is a sequence signal.

The high layer signaling may be used to configure at least one of: a modulation order of modulation symbols; a constellation of modulation symbols; a sequence set, and the like.

In one embodiment, at least two of the M samples of the response signal are modulated differently.

The high layer signaling may be used to configure at least one of: a modulation order of modulation symbols; a constellation of modulation symbols, and the like.

It is to be noted that the above embodiments are merely illustrative of the embodiments of the present invention, but the present invention is not limited thereto, and appropriate modifications may be made based on the above respective embodiments. For example, each of the above embodiments may be used alone, or one or more of the above respective embodiments may be combined. Further, M is greater than or equal to N, M is greater than or equal to 2 (or greater than or equal to 3), and N may be greater than or equal to 1. In one example, M can also be a positive integer and an odd number, and M is greater than or equal to 2 (or greater than or equal to 3). In the above embodiments, the high layer signaling may also be used to configure the value of M.

In addition, the terminal device may be a sending device of the response signal, and the high-level signaling indicates a sending mode to the terminal device; the terminal device may further be a receiving device of the response signal, where the high-layer signaling indicates to the terminal device Receiving method.

The method of transmitting/receiving the M samples corresponding to the response signal corresponding to the data may be stipulated by the communication standard specification or preset in the network device and/or the terminal device. For example, the foregoing sending/receiving manner indicated by the high layer signaling to the terminal device is agreed by the communication standard specification or preset in the network device and/or the terminal device. In addition, in the parameters and/or transmission modes involved in the foregoing transmission/reception mode, some may be configured by higher layer signaling, and another part is agreed by the communication standard specification or preset in the network device and/or the terminal device. .

In addition, in this embodiment, the receiving device receiving the response signal may perform a merge processing on the received M samples, and may obtain a merge processing gain. The receiving device can also process the M samples separately by receiving the response signal, and the result is more as the final result. For example, M is equal to 3, and if 2 ACKs and 1 NACK are interpreted, it can be determined as ACK; the following can be avoided: when one of the samples is extremely poor in reliability, the merge processing may be lowered. The reliability of other good quality received signals, which in turn affects the combined results.

The above two processing methods can be respectively applied to different transmission environments. For example, in an indoor environment, a low-frequency (below 6 GHz) deployment, or a low-speed mobile transmission environment, the probability that a certain sample experiences extreme spread is very small, and the merge processing is relatively It will get better results when processed separately. For another example, in an outdoor environment, when moving at a high speed or when deployed in a frequency band greater than 6 GHz, the probability of one of the M samples experiencing the poor propagation is greater than in the former case, and then a separate treatment may achieve better results.

In indoor environments, the signal-to-noise ratio of signal propagation is high; in outdoor environments, the signal-to-noise ratio is low, and individual samples are prone to experience extremely poor propagation environments. In the low-speed propagation environment, the channel experienced by the signal changes slowly, and the channel quality is stable. In the high-speed propagation environment, the channel experienced by the channel changes rapidly, and the probability of deep fading is too large, and individual samples are prone to experience extremely poor. Spread the environment. Low-frequency deployment below 6 GHz, the carrier frequency is low, and the signal quality is stable compared to the deployment above 6 GHz. The high-frequency deployment above 6 GHz is more prone to signal blockage and the probability of sudden signal interruption. Low frequency deployments above 6 GHz, so individual samples are prone to very poor propagation conditions.

In actual network deployment, it is possible to deploy in indoors or outdoors, and the terminal devices of network services are at high speed or low speed. Therefore, the above various embodiments and processing methods of network devices can be implemented according to actual conditions. The deployment and the terminal devices of the service are used in combination or separately to obtain the maximum gain in the actual case.
