Description

Technical Field

[0001] The embodiments of the present disclosure generally relate to the field of communication technology, and more specifically, relate to a method, an electronic device, a computer-readable storage medium, and a computer program product in communication. Background Art

[0002] In wireless communication, the most important and difficult task is to combat the variability and uncertainty in the wireless transmission environment. From the transmitter side, an efficient communication method can make better use of instantaneous channel information and perform appropriate information / signal preprocessing at the transmitter side so that the transmission can match the instantaneous channel capacity. This problem is even more important and complex in multi-user communication and multi-antenna communication.

[0003] In order to achieve this function, the transmitter needs to obtain instantaneous channel information before transmission. Obviously, the more accurate the instantaneous channel information obtained by the transmitter, the better. The most common way to obtain instantaneous channel information is to perform channel measurement. Specifically, the channel measurement can be performed at the transmitter or at the receiver. In a time division duplex (TDD) system, because the channel from the transmitter to the receiver has good reciprocity with the channel from the receiver to the transmitter, the transmitter can obtain instantaneous channel information by estimating the channel from the receiver to the transmitter. In cellular communication networks, including long-term evolution LTE and new radio NR, when the mobile network transmits data to the user equipment through the base station, the user terminal transmits a reference signal to the user to help the base station obtain the instantaneous channel information from the base station to the user terminal. These reference signals are also called sounding reference signals (SRS). The base station can configure the user equipment to send SRS periodically, or trigger the user equipment to send SRS non-periodically through a mechanism. This mechanism is also likely to continue to be used in future cellular communication systems. However, there is still room for further optimization and improvement in reference signals in communication systems. Summary of the invention

[0004] The embodiment of the present disclosure provides a communication method. The embodiment of the present disclosure improves the sequence capacity by determining a reference signal according to a combination of a first sequence and a second sequence, provides a combination of different first sequences and second sequences, and maintains the correlation performance of the second sequence.

Thus, by selecting the first sequence and the second sequence, the sequence capacity is increased and a good correlation is maintained.

[0006] In some embodiments of the first aspect, the first perfect sequence and the second perfect sequence have different periods or different constellation sets. Thus, the reference signal can be determined by using sequences with different periods or constellation diagrams, so that the first sequence and the second sequence have different selections, to obtain different pilot sequences to determine the reference signal.

[0007] In some embodiments of the first aspect, the first perfect sequence comprises a third perfect sequence, and the second perfect sequence comprises a second perfect sequence, so that the first sequence and the second sequence have different selections to obtain different pilot sequences to determine the reference signal.

[0008] In some embodiments of the first aspect, the first perfect sequence comprises a quadratic perfect sequence, and the second perfect sequence comprises a perfect sequence extended based on a cyclic Florentine matrix, thereby making the first sequence and the second sequence have different selections to obtain different pilot sequences to determine the reference signal.

[0009] In some embodiments of the first aspect, the addition index and sequence include at least one of the following: a ZC sequence, a generalized Frank sequence, a perfect sequence, or an m sequence. Thus, the first sequence and the second sequence have different selections to obtain different pilot sequences to determine the reference signal.

[0010] In some embodiments of the first aspect, the multiplication index and the sequence include at least one of: a Legendre sequence or a Sidelnikov sequence. Thus, the first sequence and the second sequence are selected differently to obtain different pilot sequences to determine the reference signal.

[0011] In some embodiments of the first aspect, the reference signal includes a sounding reference signal (SRS) or a demodulation reference signal (DMRS). Thus, the SRS or DMRS can be determined by the first sequence and the second sequence.

[0012] In some embodiments of the first aspect, the method is performed by a terminal device or a network device. Thus, the sequence can be determined at the terminal or the network device.

[0013] In a second aspect of the present disclosure, a method is provided.

Thus, by selecting the first sequence and the second sequence, the sequence capacity is increased and a good correlation is maintained.

[0014] In some embodiments of the second aspect, the first perfect sequence and the second perfect sequence have different periods or different constellation sets. Thus, the reference signal can be determined by using sequences with different periods or constellation diagrams, so that the first sequence and the second sequence have different selections, to obtain different pilot sequences to determine the reference signal.

[0015] In some embodiments of the second aspect, the first perfect sequence comprises a third perfect sequence, and the second perfect sequence comprises a second perfect sequence, thereby enabling the first sequence and the second sequence to have different selections to obtain different pilot sequences to determine the reference signal.

[0016] In some embodiments of the second aspect, the first perfect sequence comprises a quadratic perfect sequence, and the second perfect sequence comprises a perfect sequence based on a cyclic Florentine matrix extension, thereby making the first sequence and the second sequence have different selections to obtain different pilot sequences to determine the reference signal.

[0017] In some embodiments of the second aspect, the addition index and sequence include at least one of: a ZC sequence, a generalized Frank sequence, a perfect sequence, or an m sequence. Thus, the first sequence and the second sequence have different selections to obtain different pilot sequences to determine the reference signal.

[0018] In some embodiments of the second aspect, the multiplication index and the sequence include at least one of: a Legendre sequence or a Sidelnikov sequence. Thus, the first sequence and the second sequence are selected differently to obtain different pilot sequences to determine the reference signal.

[0019] In some embodiments of the second aspect, the reference signal includes a sounding reference signal (SRS) or a demodulation reference signal (DMRS). Thus, the SRS or DMRS can be determined by the first sequence and the second sequence.

[0020] In some embodiments of the second aspect, the method is performed by a terminal device or a network device. Thus, the sequence can be determined at the terminal or the network device.

[0033] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the embodiments of the present disclosure can be implemented in various forms and should not be interpreted as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the embodiments of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0034] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "the", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.

[0035] In the description of the embodiments of the present application, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". It should be understood that the expressions "first", "second", "third" and the like are only intended to indicate that multiple objects may be different, but at the same time do not exclude that two objects are the same. The expressions "first", "second", "third" and the like should not be interpreted as any limitation on the embodiments. The terms "first" and "second" are used for descriptive purposes and should not be understood as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" is two or more. The following may also include other explicit and implicit definitions.

[0036] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0037] As mentioned above, the user terminal transmits a reference signal (such as SRS) to the user to help the base station obtain instantaneous channel information from the base station to the user terminal. Furthermore, because the cellular network needs to be networked and serve multiple users, when the device sends SRS, the SRS needs to support a certain capacity, and the correlation between SRSs is relatively good to avoid SRS interference between user devices within and between cells. Specifically, when a base station receives SRS signals from multiple user devices in the cell at the same time, if multiple SRS resources occupy non-orthogonal time-frequency resources, without loss of generality, it is assumed that two SRS signals occupy the same time-frequency resources. The lower the correlation between the two SRSs, the lower the interference of another SRS signal to the SRS signal currently being solved when each SRS signal is solved to estimate the channel between the user device and the base station corresponding to the signal, and the more realistic the channel between the user device and the base station can be obtained through the SRS signal currently being solved.

[0038] At the receiving end, in order to achieve correct reception and demodulation of data, it is also necessary to obtain instantaneous channel information. This can be achieved by transmitting specific information known to both the transceiver and the transmitter on some specific time-frequency resources. The information carried is also called the demodulation reference signal (DMRS). At the receiving end, on the time-frequency resources corresponding to the DMRS, because the information transmitted by the DMRS is known, it can decode the channel through which the DMRS passes, that is, the channel from the transmitter to the receiver. However, there is still room for further optimization and improvement in reference signals (e.g., SRS, DMRS, or any other reference signal) in the communication system.

[0039] In view of this, the embodiments of the present disclosure specifically propose a solution. In some exemplary aspects, the solution of the embodiments of the present disclosure improves the capacity of the sequence by designing a combination of two groups of sequences of different types, includes a new combination of different types of sequences, and maintains the relevant performance of the sequence.

[0040] Figure 1 Schematic diagram of an example environment in which various embodiments of the present disclosure can be implemented. Figure 1 As shown, the example environment includes a first device 110 (eg, first communication device 110) and a second device 120 (eg, second communication device 110). The first device 110 and the second device 120 may communicate with each other, for example, via a wireless link.

[0041] In some embodiments, the first device 110 or the second device 120 may be a network device, such as a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The first device 110 or the second device 120 may be a macro base station, a micro base station or an indoor station, a relay node or a donor node. Optionally, the first device 110 or the second device 120 may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the first device 110 or the second device 120 in the embodiment of the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). The first device 110 or the second device 120 in the embodiment of the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the first device 110 or the second device 120.

[0042] In some embodiments, the first device 110 or the second device 120 may be a terminal device, such as a user equipment (UE), a mobile station, a mobile terminal, etc. The first device 110 or the second device 120 may be widely used in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The first device 110 or the second device 120 may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the first device 110 or the second device 120.

[0043] It should be noted that, in some examples, one of the first device 110 and the second device 120 is a network device, and the other of the first device 110 and the second device 120 is a terminal device. In other examples, both the first device 110 and the second device 120 can be terminal devices. In other examples, both the first device 110 and the second device 120 can be network devices. In addition, Figure 1 In the figure, the first device 110 is illustrated by taking a user equipment as an example, and the second device 120 is illustrated by taking a base station as an example. The embodiments of the present application do not limit the device forms of the first device and the second device.

[0044] Specifically, Figure 1 A typical wireless network transmission scenario is shown, such as LTE or NR and possible 6G wireless application scenarios in the future, in which a base station 120 and a user equipment 110 are included. Certain functions such as synchronization, channel estimation, and perception need to be completed through sequences between the base station 120 and the user equipment 110. In the embodiment of the present disclosure, the base station 120 mainly completes the detection and / or estimation of the uplink channel by accepting the pilot sequence (SRS or DMRS) of the user end. Optionally, the detection / estimation result can be applied to the downlink channel by the reciprocity of the channel, or the user can complete the detection and estimation of the downlink channel by accepting the pilot sequence of the base station. The embodiment of the present application provides a sequence-based channel detection and / or estimation scheme. The user end sends a pilot signal (SRS or DMRS), and the base station accepts the pilot sequence (SRS or DMRS) of the user end to complete the detection and / or estimation of the uplink channel, and optionally, the detection / estimation result can be applied to the downlink channel by the reciprocity of the channel. It is also possible that the user completes the detection and estimation of the downlink channel by accepting the pilot sequence of the base station.

[0045] Understandably, Figure 1 The number of the first device and the second device shown in the figure is an example and is not intended to impose any limitation. According to actual needs, the communication network 100 may include any appropriate number of network elements of various types.

[0046] With the development of multi-antenna technology and the improvement of multi-user demand, the number of pilots that need to be used simultaneously, including the number of SRS and the number of DMRS, is increasing day by day, so the demand for large-capacity pilot sequences is also increasing. This is also reflected in the progress of the LTE and NR standard evolution. For example, in the initial version (release) 15 of NR, the sequence and generation method of DMRS of SRS are specified. In the subsequent research and standardization process of versions 16-19, there have almost always been corresponding research topics or standard topics to enhance the capacity of SRS and DMRS. Therefore, in the design of new mobile communications, the possible future SRS and DMRS capacity requirements are taken into account from the beginning, starting with the selection of sequences, and large-capacity SRS and DMRS are designed based on large-capacity sequences. Similar considerations apply to reference signals other than SRS and DMRS.

[0047] Or different. A set of preferred N and M is as follows. For example, take N=M, when the RS sequence length is 6, select the ZC sequence generation length N as 7. When the RS sequence length is 12, select the ZC sequence generation length N as 11 or 13. When the RS sequence length is 18, select the ZC sequence generation length N as 17 or 19. When the RS sequence length is 24, select the ZC sequence generation length N as 23 or 29. When the RS sequence length is greater than or equal to 30, select the ZC sequence generation length to be the maximum prime number less than the RS sequence length or the minimum prime number greater than the RS sequence length. After the first sequence is combined with the second sequence, the RS sequence length for actual transmission is lengthened or shortened by cyclic shift. The problem with this method is that the types of the two groups of sequences used to generate the pilot sequence are limited.

[0048] Figure 2 FIG. 1 is a schematic diagram showing a signaling process according to some embodiments of the present disclosure. Figure 2 As shown, in some embodiments, the first device 110 sends 201 a reference signal 202 to the second device 120. The second device 120 receives 203 the reference signal 202. In some embodiments, the reference signal is determined based on the first sequence and the second sequence. In some embodiments, the reference signal 202 may include a sounding reference signal (SRS) or a demodulation reference signal (DMRS). In other embodiments, the reference signal 202 may also include any other reference signal currently known or developed in the future.

[0049] In some embodiments, the first sequence includes a first perfect sequence, and the second sequence includes a second perfect sequence. A perfect sequence is a sequence in which the periodic autocorrelation function reaches a maximum value when it is fully aligned, i.e., shifted to 0, and is 0 everywhere in other positions. For example, the following representation is a perfect sequence. The length of the cubic sequence is 25, a takes values ​​of 0, 5, 10, 15, 20, 25, and b takes values ​​of all values ​​0-25 except a. A ZC or generalized Frank sequence with a secondary sequence length of 37 is shortened to 36, and after synthesis, a 36-bit pilot sequence can be generated for detection / channel estimation, etc. That is Where N = p k ,a mod N ≠ 0,b mod p ≠ 0,p = 3; or Where N = p k ,a mod N≠0,b mod p≠0,a mod N≠0,p≥5.

[0050] In some embodiments, the first sequence comprises additive exponents and sequences and the second sequence comprises multiplicative exponents and sequences.

[0051] Through the above scheme, the reference signal can be determined according to the combination of the first sequence and the second sequence, thereby improving the sequence capacity, providing different combinations of the first sequence and the second sequence, and maintaining the correlation performance of the second sequence.

[0052] In some embodiments, the first perfect sequence and the second perfect sequence have different periods or different constellation sets.

[0053] In some embodiments, the first perfect sequence comprises a third perfect sequence and the second perfect sequence comprises a second perfect sequence.

[0054] In some embodiments, the first perfect sequence includes a quadratic perfect sequence, and the second perfect sequence includes a perfect sequence based on a cyclic Florentine matrix extension. Specifically, when the cyclic Florentine matrix extension constellation point is PSK+, synthesis can be performed in the frequency domain. PSK+ refers to a constellation point set of Where N-1≥n≥0.

[0055] When the cyclic Florentine matrix expands the constellation point to APSK+, it can be synthesized in the frequency domain or time domain. APSK+ means that the constellation point set is

[0056] Where N-1≥n≥0,M-1≥m≥0,R-1≥R≥0,c 0 ,c 1 ,…,c K-1 ,d 0 ,d 1 ,…,d K-1 is a constant, c0 ,c 1 ,…,c K-1 N, M, R, K are constants.

[0057] In some embodiments, the additive exponent and sequence include at least one of the following: a ZC sequence, a generalized Frank sequence, a perfect sequence, or an m sequence. Specifically, the multiplicative exponent and sequence selects a perfect sequence such as a ZC sequence, a generalized Frank sequence, and its general formula can be written as

[0058] In some embodiments, the multiplication index and sequence include at least one of the following: Legendre sequence or Sidelnikov sequence. That is, the second sequence can select Legendre sequence, which can be expressed as in represents the Legendre symbol. Or the second sequence can be a perfect sequence such as the ZC sequence or the generalized Frank sequence, and its general formula can be written as At this time, the first sequence selects the Legendre sequence, which can be expressed as in Represents Legendre symbol. When the Legendre sequence is selected as the member sequence, the Legendre sequence is selected as a long sequence and then truncated for frequency domain synthesis, which can maintain the perfect sequence characteristics.

[0059] The above technical solution generates an SRS or DMRS sequence through a first sequence and a second sequence. The first sequence and the second sequence select different perfect sequences, or the first sequence selects an additive index and sequence, and the second sequence selects a multiplicative index and sequence, or vice versa, to generate the final pilot sequence. When the first sequence is the same and the second sequence is different, or when the first sequence is different and the second sequence is the same, the optimal correlation theoretical boundary can be obtained. That is the theoretical optimal value.

[0060] Figure 3 A block diagram of a method according to some embodiments of the present disclosure is shown. In block 310, a reference signal is sent, wherein the reference signal is determined based on a first sequence and a second sequence. The first sequence includes a first perfect sequence, and the second sequence includes a second perfect sequence. Alternatively, the first sequence includes an additive index and a sequence, and the second sequence includes a multiplicative index and a sequence. Thus, by selecting the first sequence and the second sequence, the sequence capacity is increased and a good correlation is maintained.

[0061] It is understood that method 300 may also include the following references: Figure 1 to Figure 2Any other operations or actions described above that are performed by the first communication device (eg, the terminal device 110 or the network device 120) in some embodiments of the present application will not be described in detail herein.

The first sequence includes a first perfect sequence, and the second sequence includes a second perfect sequence. Alternatively, the first sequence includes an additive index and a sequence, and the second sequence includes a multiplicative index and a sequence. Thus, different first and second sequences can be used to generate the reference signal, thereby increasing the sequence capacity and maintaining a good correlation.

[0063] It is understood that method 400 may also include the following references: Figure 1 to Figure 2 Any other operations or actions described above that are performed by the second communication device (eg, the terminal device 110 or the network device 120) in some embodiments of the present application will not be described in detail herein.

The first communication device 500 may be implemented as a device or a chip in a device, and the scope of the present application is not limited in this respect. The first communication device 500 may include multiple modules for performing the following steps: Figure 3 For example, the first communication device 500 may be implemented as follows: Figure 1 Alternatively, the first communication device 500 may be implemented as follows: Figure 1 The second device 120 or the chip therein shown in FIG. Figure 1 , Figure 2 as well as Figure 3 right Figure 5 Give a description.

[0065] like Figure 5 As shown, the first communication device 500 includes a transmitting module 510. In some embodiments, the first communication device 500 may also include a receiving module 520 and / or a processing module 530. The transmitting module 510 is used to send data, the receiving module 520 is used to receive data, and the processing module 530 is used to process data. For example, the transmitting module 510 is used to send a reference signal (e.g., Figure 2The reference signal 202 is shown in FIG. 1 ). The reference signal is determined based on the first sequence and the second sequence. The first sequence includes a first perfect sequence, and the second sequence includes a second perfect sequence. Alternatively, the first sequence includes an additive index and a sequence, and the second sequence includes a multiplicative index and a sequence. In this way, the reference signal can be determined based on a combination of the first sequence and the second sequence, thereby improving the sequence capacity, providing a combination of different first sequences and second sequences, and maintaining the correlation performance of the second sequence.

[0068] like Figure 6 As shown, the first communication device 600 includes a receiving module 610.

The first sequence includes a first perfect sequence, and the second sequence includes a second perfect sequence. Alternatively, the first sequence includes an additive index and a sequence, and the second sequence includes a multiplicative index and a sequence. In this way, the reference signal can be determined according to a combination of the first sequence and the second sequence, thereby improving the sequence capacity, providing a combination of different first sequences and second sequences, and maintaining the correlation performance of the second sequence.

[0069] It is understandable that the first communication device 600 may also include various other modules, respectively used to execute the Figures 1 to 4 Any other operations or actions described above that are performed by the second communication device in some embodiments of the present application will not be described in detail herein.
