Description

[Technical Field]

[0001] This application is filed based on and claims priority from a Chinese patent application bearing application number 202110777758.6 and filing date July 9, 2021, the entire contents of which are hereby incorporated by reference into this application.

[0002] The present application relates to the technical field of wireless communication networks, for example, to a signal transmission method, a signal reception method, a communication node, and a storage medium. [Background technology]

[0003] Traditional communication nodes such as base stations primarily provide information transmission services. However, to meet the demands of typical services in new scenarios such as the Internet of Vehicles, smart factories, and augmented reality, in the future, base stations will have both communication and perception functions. The targets perceived by a base station can be targets with communication capabilities, such as terminals, or objects without communication capabilities, such as vehicles and obstacles. To make full use of scarce frequency resources and reduce costs, the communication and perception functions can use resources such as spectrum, antennas, and baseband in the same frequency band. Such communication nodes can be called communication-perception integrated nodes.

[0004] A communication-perception integrated node may receive a communication signal and also receive a perception signal reflected back from a target. The target and the sender of the communication signal may be the same object, or they may be separate objects. The difference is as follows: The transmitted communication signal can be controlled by the communication-perception integrated node. For example, a communication-perception integrated base station controls the time of transmitting a communication signal by sending a timing advance command. On the other hand, a communication-perception integrated base station cannot control and synchronize the transmission time of a perception signal reflected back from a target. Therefore, the perception signal and communication signal that arrive at the communication-perception integrated node are usually not synchronized, and they interfere with each other, affecting the performance of communication and perception.

[0014] The present application will be described below with reference to the drawings and examples. It should be understood that the specific examples described in this specification are merely for the purpose of interpreting the present application and do not limit the present application. The examples and features of the examples of the present application may be combined with each other in any manner without contradiction. For ease of explanation, the drawings show only some, but not all, of the structures related to the present application.

[0015] In an embodiment of the present application, a signal receiving method is provided, which is applied to a first node, and the first node may be a communication-perception integrated node having functions of communication and perception.

[0016] 1 is a flowchart of a signal receiving method according to an embodiment. As shown in FIG. 1, the method according to this embodiment includes step 110 and step 120.

[0017] In step 110, transmitting indication information indicating a preset resource set for transmitting a sensory signal and timing advance information corresponding to the preset resource set.

[0018] Step 120 receives the sensory signal and the first communication signal transmitted by the second node.

[0019] In this embodiment, the first node transmits instruction information to the second node, thereby enabling the second node to transmit the first communication signal after clarifying the preset resource set and corresponding timing advance information for transmitting the perception signal. This reduces interference between the first communication signal and the perception signal. The first node transmits instruction information to the third node, thereby enabling the third node to instruct the third node on the resources and timing advance information to be used for transmitting the perception signal. This reduces interference between the perception signal and the first communication signal. Thus, the first node can receive the perception signal transmitted by the third node and the first communication signal transmitted by the second node, and the perception signal and the first communication signal are synchronized at the first node, thereby avoiding or significantly reducing mutual interference between the perception signal and the first communication signal.

[0020] FIG. 2 is a schematic diagram of a transmitted perception signal and a communication signal according to one embodiment. As shown in FIG. 2, the perception process requires cooperative operation between a first node and a third node. For example, the third node transmits a perception signal, and the first node receives the perception signal reflected by a target. Here, the first node and the third node may be different antennas or antenna panels of the same base station employing a distributed configuration, or may be different base stations that cooperate in transmitting and receiving (such a base station combines communication and perception functions, i.e., is an integrated communication-perception base station). To avoid co-channel interference between the transmitted communication signal and the perception signal, it is assumed that the first node does not transmit the communication signal on the same time-frequency resource as the transmitted perception signal, at least when receiving the perception signal. Based on this assumption, the nodes can perceive surrounding targets without relying on full-duplex technology.

[0021] The second node may be a terminal having communication capabilities capable of transmitting the first communication signal to the first node.

[0022] A target is an object that cannot transmit or receive communication signals according to the instructions of the first node. For example, a target may be a building that can directly reflect a portion of a sensory signal transmitted by a third node back to the first node. Also, for example, a target may respond to a sensory signal through its own special geometric structure or material structure design. Such special structure may encode the target's own attributes or status information, and change the reflection or absorption characteristics of electromagnetic waves. For example, a target may perform backscatter communication modulation based on the sensory signal transmitted by a third node. Furthermore, for example, a target may be a terminal that is not connected to the first node network.

[0023] In this embodiment, the third node transmits a perception signal on a preset resource set, and the first node determines timing advance information corresponding to the perception signal based on the relationship between the resource on which the perception signal is transmitted and the preset resource set. The first node transmits the preset resource set on which the perception signal is transmitted and the corresponding timing advance information to other nodes. This avoids contention between the perception signal and communication signals transmitted by different nodes, reduces interference, and improves communication and perception performance and reliability.

[0024] In one embodiment, the indication information is transmitted to the second node, the first communication signal is transmitted over resources in the pre-configured resource set, and a timing advance amount corresponding to the first communication signal is determined by the second node based on the timing advance information.

[0025] In this embodiment, the second node receives the instruction information, and can transmit the first communication signal using a corresponding timing advance mechanism based on the preset resource set sent by the first node and the timing advance information corresponding to the preset resource set.

[0026] In an example where a perceptual signal is transmitted on one pre-configured resource set, the first node typically transmits the pre-configured resource set and timing advance information corresponding to the pre-configured resource set in a broadcast or multicast manner. When the second node transmits a first communication signal using resources (including a portion of the resources) of the pre-configured resource set, the second node needs to determine the timing advance amount for transmitting the first communication signal based on the timing advance information corresponding to the pre-configured resource set to avoid interference between the perceptual signal and the first communication signal. For example, the pre-configured resource set is timeslot 1 and timeslot 2, and the second node uses timeslot 2 and timeslot 3 to transmit the first communication signal. In this case, for the first communication signal on timeslot 2, the second node needs to determine the timing advance amount for transmitting the first communication signal based on the timing advance information corresponding to the pre-configured resource set. On the other hand, for the first communication signal transmitted in timeslot 3, the timing advance information does not need to be taken into account.

[0027] In the method of this embodiment, the first node configures and indicates a predetermined resource set for a perceptual signal and timing advance information corresponding to the predetermined resource set. This ensures that the timing advance amount with which the second node transmits a first communication signal on the predetermined resource set is synchronized with the perceptual signal at the first node. Furthermore, mutual interference between the communication signal and the perceptual signal is avoided or significantly reduced. Note that the perceptual signal and the first communication signal are both transmitted on the same predetermined resource set, e.g., in the same time slot, but the frequency domain resources occupied by them can be orthogonal. Therefore, the timing with which the second node transmits the first communication signal on the predetermined resource set can be synchronized with the perceptual signal at the first node, thereby avoiding mutual interference between them.

[0028] In one embodiment, the preset resource set includes at least one of time domain resources, frequency domain resources, spatial domain resources, and code domain resources. For example, the indication information may include at least time domain resource information used to transmit the perceptual signal, and may also include one or more of frequency domain resource information, spatial domain resource information, and code domain resource information, etc.

[0029] In one embodiment, the indication information is transmitted in a broadcast or multicast manner. In this embodiment, the indication information may be transmitted by the first node and / or the third node in a broadcast or multicast manner.

[0030] In one embodiment, the timing advance amount corresponding to the timing advance information and the dedicated timing advance amount of the first communication signal are opposite in direction, e.g., the timing advance amount corresponding to the timing advance information represents a delay of several sample points, and the dedicated timing advance amount represents an advance of several sample points.

[0031] In one embodiment, the method further comprises the step 100 of transmitting dynamic instruction information, wherein the dynamic instruction information instructs the second node to determine a timing advance amount corresponding to the first communication signal in one of the following manners: for example, the second node determines a timing advance amount corresponding to the first communication signal based on the timing advance information, or determines a timing advance amount corresponding to the first communication signal based on a dedicated timing advance amount for the first communication signal, or determines a timing advance amount corresponding to the first communication signal based on the timing advance information and a dedicated timing advance amount for the first communication signal.

[0032] In this embodiment, the second node determines, in accordance with the dynamic instruction from the first node, whether to determine a timing advance amount for transmitting the first communication signal based on the relationship between the resources for transmitting the first communication signal and a predetermined resource set. For example, the first node transmits the predetermined resource set and timing advance information corresponding to the predetermined resource set, and the information is typically transmitted in a broadcast or multicast manner. To the second node transmitting a signal using resources (including a portion of resources) of the predetermined resource set, the first node transmits a command instructing whether to determine the timing advance amount using the timing advance information corresponding to the predetermined resource set. The second node determines, in accordance with the command, whether to determine the timing advance amount for transmitting the first communication signal using the timing advance information corresponding to the predetermined resource set. The dynamic instruction information also instructs the second node whether to determine the timing advance amount for transmitting the first communication signal based on a dedicated timing advance amount. The timing advance amount for transmitting the first communication signal may be determined based on the timing advance information and / or the dedicated timing advance amount corresponding to the predetermined resource set.

[0033] In one embodiment, the dynamic instruction information is transmitted through dedicated signaling to the second node, for example, a control channel or a traffic channel used to transmit the command is scrambled with a specific identification number of the second node, such as a Cell-Radio Network Temporary Identifier (C-RNTI) of the second node.

[0034] In one embodiment, the dynamic instruction information is transmitted in a broadcast or multicast manner, for example, the control channel or traffic channel used to transmit the command is scrambled with an identification number associated with the broadcast or multicast identification number associated with the second node.

[0035] Although the preset resource set is a resource set that is dedicated for transmitting perceptual signals, considering changes in traffic demand over time, the perceptual signals may not be transmitted on the preset resource set during a certain period. According to the method of this embodiment, the first node can flexibly and dynamically control whether the second node uses timing advance information corresponding to the preset resource set by using dedicated signaling or broadcast / multicast signaling, thereby improving the utilization efficiency of radio resources while ensuring perceptual performance.

[0036] In one embodiment, the indication information is transmitted to the third node, and the timing advance information is determined based on a timing advance amount corresponding to the first communication signal.

[0037] In this embodiment, the first node may send instruction information to the third node to indicate a preset resource set and corresponding timing advance information for transmitting the perceptual signal. Prior to this, the first node may have previously determined the preset resource set and corresponding timing advance information available for the third node to transmit the perceptual signal based on the resource and timing advance amount for transmitting the first communication signal of the third node to avoid interference.

[0038] In one embodiment, step 120 includes a step of preferentially receiving the first communication signal when the perceptual signal and the first communication signal conflict. In this embodiment, when the perceptual signal transmitted by the third node on the pre-configured resource set conflicts with the first communication signal transmitted by the second node, the first node preferentially receives the first communication signal transmitted by the second node. This ensures reliability of data communication.

[0039] In an embodiment of the present application, a signal transmission method applied to a second node is further provided. The second node may be a terminal capable of transmitting a first communication signal to the first node. For details of the techniques not described in detail in this embodiment, please refer to any of the above embodiments.

[0040] 3 is a flowchart of a signal transmission method according to an embodiment. As shown in FIG. 3, the method according to this embodiment includes step 210 and step 220.

[0041] In step 210, indication information indicating a preset resource set for transmitting a sensory signal and timing advance information corresponding to the preset resource set is received.

[0042] In step 220, a first communication signal is transmitted to the first node based on the indication information.

[0043] In this embodiment, the second node receives the instruction information, and thereby determines the preset resource set for transmitting the perception signal and the corresponding timing advance information, and transmits the first communication signal to the first node based on the predetermined resource set and the corresponding timing advance information, thereby avoiding contention between the first communication signal and the perception signal and improving communication and perception performance and reliability.

[0044] In one embodiment, step 220 includes step 2210 and step 2220 .

[0045] Step 2210: Determine a timing advance amount corresponding to transmitting the first communication signal based on the indication information.

[0046] Step 2220: Transmit the first communication to the first node with a timing advance amount corresponding to the first communication.

[0047] In this embodiment, the second node transmits a first communication signal using a corresponding timing advance mechanism based on a preset resource set and timing advance information corresponding to the preset resource set, and when the resource for transmitting the first communication signal conflicts with a resource in the preset resource set, the second node determines a timing advance amount for transmitting the first communication signal to reduce interference between the perceived signal and the first communication signal.

[0048] In one embodiment, the method further comprises step 200 .

[0049] Step 200: Receive dynamic instruction information sent by a first node, which instructs the second node to determine a timing advance amount corresponding to the first communication signal in one of the following manners: For example, the second node determines the timing advance amount corresponding to the first communication signal based on the timing advance information, or determines the timing advance amount corresponding to the first communication signal based on a dedicated timing advance amount for the first communication signal, or determines the timing advance amount corresponding to the first communication signal based on the timing advance information and the dedicated timing advance amount for the first communication signal.

[0050] In this embodiment, if the resources occupied by the first communication signal transmitted by the second node conflict with the preset resource set, the dynamic instruction information may instruct the second node to determine a timing advance amount for transmitting the first communication signal based on the timing advance information during the process of transmitting the first communication signal, or may instruct the second node not to determine a timing advance amount corresponding to the first communication signal based on the timing advance information. In the latter case, the second node may determine a timing advance amount corresponding to the first communication signal based on a dedicated timing advance amount, where the dedicated timing advance amount may be transmitted in advance by the first node to the second node through dedicated control information. Furthermore, if the resources occupied by the second node for transmitting the first communication signal do not conflict with the preset resource set, the final timing advance amount may be determined in a conventional manner, for example, based on the dedicated timing advance amount.

[0051] In one embodiment, step 2210 includes: If the resource occupied by the first communication signal conflicts with the preset resource set, determining a timing advance amount corresponding to the first communication signal based on the timing advance information.

[0052] For example, the second node transmits a random access preamble on a resource that conflicts with the pre-configured resource set, and in this case, the second node determines the timing advance amount of the random access preamble based on the timing advance information.

[0053] In one embodiment, step 2210 includes: When the resources occupied by the first communication signal conflict with the pre-defined resource set, the method includes determining a timing advance amount corresponding to the first communication signal based on the timing advance information and a dedicated timing advance amount for the first communication signal.

[0054] For example, the second node transmits uplink traffic data or uplink measurement pilots on resources that conflict with the pre-configured resource set. In this case, the second node can determine a final timing advance amount for transmitting the first communication signal based on both the dedicated timing advance amount and the previous timing advance information. If the dedicated timing advance amount transmits the first communication signal 10 sample points ahead and the broadcast or multicast level timing advance information transmits the first communication signal 4 sample points behind, the final timing advance amount when the second node transmits the first communication signal is 10-4=6.

[0055] In one embodiment, step 2210 includes: If the resources occupied by the first communication signal do not conflict with the preset resource set, the method includes determining a timing advance amount corresponding to the first communication signal based on a dedicated timing advance amount of the first communication signal.

[0056] In this embodiment, the second node may use the dedicated timing advance amount as the final timing advance amount when transmitting the first communication signal.

[0057] In one embodiment, the indication information is transmitted by the first node or the third node in a broadcast or multicast manner.

[0058] In one embodiment, the timing advance amount corresponding to the timing advance information and the dedicated timing advance amount of the first communication signal are opposite in direction.

[0059] In the method of this embodiment, the second node can flexibly use the timing advance information and / or the dedicated timing advance amount based on the dynamic indication information to determine a final timing advance amount, and transmit the first communication signal based on the final timing advance amount, thereby reducing interference between the first communication signal and the perceptual signal, ensuring perceptual performance, and improving the utilization efficiency of radio resources.

[0060] In an embodiment of the present application, a signal transmission method is further provided, which is applied to a third node. The third node is a node that transmits a perceptual signal, for example, a base station with a perceptual function. For technical details not described in detail in this embodiment, please refer to any of the above embodiments.

[0061] 4 is a flowchart of another signal transmission method according to an embodiment. As shown in FIG. 4, the method according to this embodiment includes step 310 and step 320.

[0062] In step 310, receiving indication information indicating a preset resource set for transmitting a sensory signal and timing advance information corresponding to the preset resource set.

[0063] In step 320, a sensory signal is sent to the first node based on the indication information.

[0064] In this embodiment, the first node transmits a predetermined resource set and timing advance information corresponding to the predetermined resource set to the third node. Here, the predetermined resource set and the timing advance information corresponding to the predetermined resource set may be determined by the first node based on the resources and timing advance amount of a first communication signal from a second node that is the target of the first node's service. Furthermore, the first node may transmit a beam, power, and / or time-frequency resource corresponding to the predetermined resource set and a perception signal on the predetermined resource set. The third node receives the instruction information and transmits the perception signal based on the corresponding timing advance information on the predetermined resource set in accordance with the instruction information. This reduces interference with the first communication signal and improves communication and perception performance and reliability.

[0065] In one embodiment, the timing advance information is determined based on a timing advance amount corresponding to a first communication signal transmitted by the second node.

[0066] In this embodiment, by adjusting the timing advance at which the first node transmits the third node perception signal, the transmission of the perception signal by the third node and the transmission of the first communication signal by the second node can be synchronized at the first node, reducing mutual interference between them without affecting the first communication signal transmission of the second node itself, and ensuring maximum backward compatibility of the system.

[0067] In an embodiment of the present application, a signal transmission method applied to a first node is further provided. The first node may be a communication-perception integrated node having a communication function and a perception function. For technical details not described in detail in this embodiment, refer to any of the above embodiments.

[0068] 5 is a flowchart of yet another signal transmission method according to an embodiment. As shown in FIG. 5, the method according to this embodiment includes steps 410, 420, and 430.

[0069] In step 410, a sensory signal is received.

[0070] Step 420 determines a timing advance amount for transmitting the second communication signal based on the resource for transmitting the perceptual signal.

[0071] In step 430, the second communication signal is transmitted with a timing advance amount for transmitting the second communication signal.

[0072] In this embodiment, the second communication signal is a communication signal transmitted by the first node to another node. The timing advance amount for transmitting the second communication signal is determined based on the resource for the perception signal. That is, the first node adjusts the timing advance amount for transmitting its own communication signal based on the resource for transmitting the perception signal. This reduces interference between the perception signal and the communication signal at the first node, thereby improving communication and perception performance and reliability.

[0073] In one embodiment, the perceptual signal is transmitted over K consecutive symbols within a time slot. The timing advance for transmitting the second communication signal is determined by the symbol index [K1+Δ,K] within the time slot, where K is less than M. k +Δ] range, where Δ is a positive integer less than or equal to MK, K1 is the index of the starting symbol among K consecutive symbols, and K k is the index of the ending symbol in the sequence of K consecutive symbols.

[0074] In one embodiment, the perception signal is transmitted over K consecutive symbols within a time slot. When K is equal to M, the amount of timing advance for transmitting the second communication signal satisfies not transmitting the second communication signal over symbols that conflict with the perception signal, where the symbol index belongs to the range [K1+Δ, M] within the time slot and the symbol index belongs to the range [0, Δ] within the next time slot. Here, Δ is a positive integer not exceeding M-K, K1 is the index of the starting symbol among the K consecutive symbols, and M is the total number of symbols within the time slot.

[0075] In this embodiment, the perception signal is transmitted over a preset resource set. The instruction information transmitted by the first node includes the preset resource set and the timing advance information corresponding to the preset resource set, and the above information is usually transmitted in a broadcast or multicast manner. The instruction information transmitted by the first node may include time domain resource information used to transmit the perception signal. The time domain resource information may be the time slot used to transmit the perception signal and the time domain symbol information within the time slot. Assuming that one time slot includes M symbols with indexes 1, 2......M respectively. The perception signal transmitted by the third node is transmitted over K consecutive symbols in at least one time slot (1≦K≦M). When the perception signal is transmitted over K consecutive symbols in time slot n and the indexes of these K symbols in the time slot are K1, K 2、... K K Let's assume.

[0076] K K <M (or K<M), (K K +Δ)<=M is required, where Δ is an integer greater than or equal to 0 (M-K K ). The first node is at least the symbol index set [K1+Δ, K in time slot n K+Δ].

[0077] K K =M, the first node is required not to transmit a second communication signal on resources that conflict with received perceptual signals at least in symbol index set [K1+Δ,M] for time slot n and symbol index set [0,Δ] for time slot (n+1).

[0078] Therefore, in the process of the first node receiving the perceptual signal transmitted by the third node, co-channel interference caused by echo and radio frequency leakage of the communication signal transmitted by the first node is avoided, and the perceptual performance of the perceptual signal is ensured.

[0079] An embodiment of the present application further provides a signal transmission method applied to a third node. The third node is a node that transmits a perceptual signal, for example, a base station with a perceptual function, and the third node also has a communication function. In this case, the third node is also the first node, i.e., a communication-perceptual integrated node. Note that for technical details not described in detail in this embodiment, please refer to any of the above embodiments.

[0080] 6 is a flowchart of a further signal transmission method according to an embodiment. As shown in FIG. 6, the method according to this embodiment includes steps 510, 520, and 530.

[0081] In step 510, a sensory signal is transmitted.

[0082] Step 520 determines a timing advance amount for transmitting the third communication signal based on the resource for transmitting the perceptual signal.

[0083] In step 530, the third communication signal is transmitted with a timing advance amount for transmitting the third communication signal.

[0084] In this embodiment, the third communication signal is a communication signal transmitted by the third node to another node. The timing advance amount for transmitting the third communication signal is determined based on the resource of the perception signal, i.e., the third node adjusts its communication signal transmission strategy based on the resource for transmitting the perception signal. This avoids interference or contention between the perception signal and the communication signal, and improves communication and perception performance and reliability.

[0085] In one embodiment, the perceptual signal is transmitted over K consecutive symbols within a time slot. The timing advance for transmitting the third communication signal is determined by the symbol index [K1-Δ,K] within the time slot, where K1 is greater than 1. k -Δ], where K1 is the index of the starting symbol among K consecutive symbols, and K k is the index of the ending symbol among K consecutive symbols, and Δ is a positive integer less than or equal to K1.

[0086] In one embodiment, the perceptual signal is transmitted over K consecutive symbols within a time slot, and the timing advance amount for transmitting the third communication signal satisfies the following: if K1 equals 1, then the third communication signal is not transmitted over symbols in the previous time slot that conflict with the perceptual signal and whose symbol index is in the range [M-Δ,M], where Δ is a positive integer less than or equal to K1, and M is the total number of symbols in the time slot.

[0087] In this embodiment, the perceptual signal is transmitted on a preset resource set. The indication information transmitted by the first node includes the preset resource set and timing advance information corresponding to the preset resource set, and may also include time-domain resource information used to transmit the perceptual signal. The time-domain resource information may be information about a time slot used to transmit the perceptual signal and time-domain symbol information within the time slot. Assume that one time slot includes M symbols, with indices 1, 2, ..., M, respectively. The perceptual signal transmitted by the third node is transmitted on K consecutive symbols (1≦K≦M) in at least one time slot. Assume that the perceptual signal is transmitted on K consecutive symbols in time slot n, and the indices of the K symbols in the time slot are K1, K2, K3, K4, K5, K6, K7, K8, K9, K10, K11, K12, K13, K14, K15, K16, K17, K18, K19, K20, K21, K22, K23, K24, K25, K26, K27, K28, K29, K30, K31, K32, K33, K34, K35, K36, K37, K38, K39, K40, K41, K42, K43, K44, K45, K46, K47, K48, K49, K50, K51, K52, K53, K54, K55, K56, K57, K58, K59, K60, K61, K62, K63, K64, K65, K66, K67, K68, K69, K70, K71, K72, K73, K74, K75, K75, K76, K77, K78, K79, K80, K81, K82, K83, K84, 2、... K K Let us assume that:

[0088] If K1>1, then (K1-Δ)≧1 is required, where Δ is an integer greater than 0 and less than or equal to K1.
