[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 202411897859.7, filed in China on December 20, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of wireless communication technology, and in particular to a signal transmission method, a signal reception method, an apparatus, a device, a storage medium, and a computer program product. Background Technology

[0004] In related technologies, there are two scheduling methods for uplink data transmission. One is dynamic grant (DG), where the terminal device sends a scheduling request (SR) / buffer status report (BSR) to the base station via Media Access Control (MAC) signaling, including the amount of uplink data to be transmitted. The base station then issues dynamic scheduling instructions for uplink transmission through the Physical Downlink Control Channel (PDCCH). The other is semi-static grant (CG), where uplink data is transmitted directly within the configured period without requiring a request from the terminal device. This effectively saves transmission latency and ensures uplink data transmission latency requirements are met. Therefore, base stations typically configure periodic resources for terminal uplink data transmission using Radio Resource Control (RRC) in a semi-static manner.

[0005] However, since semi-static resources are pre-configured, resource waste can occur when users' uplink data transmission needs change. How to reduce the waste of pre-configured semi-static resources has become an urgent technical problem to be solved. Summary of the Invention

[0103] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0104] Embodiments of this disclosure provide a signal transmission method. Referring to FIG1, the method is applied to a transmitting device and includes the following steps:

[0105] Step 101: If the first signal collides or overlaps with the reference signal, the first signal is transmitted based on the transmission method of the first signal.

[0106] In this embodiment, the transmitting device can be a device used to transmit network communication signals in a communication network. The first signal is a pilot signal in the communication signal, namely a superimposed pilot (SIP). The reference signal can be a channel state information-reference signal (CSI-RS). A collision or overlap between the first signal and the reference signal means that the transmission resources of the first signal and the reference signal conflict. When the first signal collides or overlaps with the reference signal, the transmission mode of the first signal is determined, and the first signal is transmitted according to the transmission mode. When transmitting the first signal, the transmission resources can also transmit other signals simultaneously, such as the reference signal, and further, the data content to be transmitted.

[0107] For example, this disclosure provides a novel approach to handling the relationship between pilot signals and data transmission in a wireless communication system: non-orthogonal pilot and data superposition transmission. This means that at the transmitting end (hereinafter referred to as the transmitter), pilot signals and data can be transmitted in a non-orthogonal manner, for example, simultaneously transmitting pilot signals and data on the same time and frequency domain resources, thus ensuring that pilot signals and data share wireless transmission resources. At the receiving end (hereinafter referred to as the receiver), it is desirable to utilize advanced Artificial Intelligence (AI) / Machine Learning (ML) receivers to achieve effective data reception from the mixed transmission of pilot signals and data, ensuring equivalent data reception on transmission resources and improving the overall system transmission gain. A corresponding schematic diagram of a superimposed pilot signal technology implementation is shown in Figure 2. Correspondingly, the basic mathematical model of SIP technology can be represented by the following formula: in, Let S be the transmission symbol matrix of the l-th layer, where S is the number of allocated subcarriers and T is the number of consecutively allocated OFDM symbols. Let l be the pilot matrix of the l-th layer. Let be the data matrix of the l-th layer, where 0 ≤ α ≤ 1 represents the power allocation ratio. Different pilots are orthogonal to each other through one or more of the following techniques: Time-Division Multiplexing (TDM), Frequency-Division Multiplexing (FDM), and Code-Division Multiplexing (CDM).

[0108] Correspondingly, this disclosure provides an application scenario, as shown in Figure 3, where the number of transmission layers is 2. For each RE in each layer, pilot signals and data are transmitted simultaneously, with a pilot-to-data weight ratio of 0.1:0.9. Pilot signals from different layers are orthogonal using code division multiplexing (CDM). It can be seen that the total energy of each layer in each RE is 1, and the total energy of all layers on each RE is 2. The pilot power accounts for an average weight of 10% of the total transmitted signal power.

[0109] Correspondingly, this disclosure also provides an application scenario, as shown in Figure 4, where the transmission layer number is 4. All symbols in the four layers can be divided into pilot-dominated or data-dominated symbols. The pilot-to-data weight ratio for pilot-dominated symbols is 1.6:0.6, while the pilot-to-data weight ratio for data-dominated symbols is 0:0.6. The pilots of different layers are orthogonal through time-division multiplexing (TDM). Therefore, the total energy of all layers on each RE is 4. The average weight of pilot power in the total transmitted signal power is 40% (=1.6 / 4). In Figure 4, columns 1, 4, and 9 of layer 1 are used to transmit both L1 pilot signals and L1 data simultaneously, with a pilot-to-data power ratio of 1.6:0.6. The remaining columns transmit only L1 data, with an L1 pilot-to-data power ratio of 0:0.6. Similarly, columns 2, 6, and 10 of layer 2 are used to transmit both L2 pilot signals and L2 data simultaneously, with a pilot-to-data power ratio of 1.6:0.6. The remaining columns transmit only L2 data, with an L2 pilot-to-data power ratio of 0:0. 0.6; In layer 3, columns 3, 7, and 11 are used to transmit L3 pilots and L3 data simultaneously, with a pilot to data power ratio of 1.6:0.6. The remaining columns only transmit L3 data, with an L3 pilot to L3 data power ratio of 0:0.6. In layer 4, columns 4, 8, and 12 are used to transmit L4 pilots and L4 data simultaneously, with a pilot to data power ratio of 1.6:0.6. The remaining columns only transmit L4 data, with an L4 pilot to L4 data power ratio of 0:0.6.

[0110] Based on the foregoing embodiments, in other embodiments of this disclosure, the method further includes the following steps:

[0111] When one or more first resource elements (REs) are used to transmit a first signal and a reference signal, the first signal and the reference signal collide or overlap.

[0112] In this embodiment of the disclosure, one method to determine whether a first signal and a reference signal collide or overlap is to determine the resource element transmitting the first signal. If it is detected that the resource element transmitting the first signal is also used to transmit the reference signal, then it can be determined that the first signal and the reference signal collide or overlap. Alternatively, another method is to determine the resource element transmitting the reference signal. If it is detected that the resource element transmitting the reference signal is also used to transmit the first signal, then it can be determined that the first signal and the reference signal collide or overlap. In this way, resource elements that simultaneously transmit the first signal and the reference signal can be determined, resulting in one or more first resource elements (REs).

[0113] Based on the foregoing embodiments, in other embodiments of this disclosure, when the sending method is the first method, the first method includes at least one of the following:

[0114] Do not send the first signal to one or more first REs;

[0115] One or more ports of the first signal corresponding to one or more first REs are in an enabled state;

[0116] Do not send one or more streams of PDSCH or PUSCH corresponding to the first signal.

[0117] In this embodiment of the disclosure, the first approach is to not transmit information related to the first signal, and also not transmit reference signals for collisions or overlaps on resource elements where collisions or overlaps occur. Specifically, the first approach can be implemented in at least one of the following ways: one is to not transmit the first signal for one or more determined first REs; another is to set one or more ports of the first signal where collisions or overlaps occur to a disabled state, i.e., a state where the first signal is not generated; yet another is to determine the flow of the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) corresponding to the first signal, and then implement the non-transmission of the first signal by not transmitting one or more flows included in the PDSCH or PUSCH corresponding to the first signal.

[0118] It should be noted that when the receiving device is a user-side terminal device, the first signal can be prevented from being sent by not sending one or more streams included in the PDSCH corresponding to the first signal. When the receiving device is a network device, i.e., a device that provides network services to the terminal device, such as a base station or network access node, one or more streams included in the PUSCH corresponding to the first signal are not sent.

[0119] Based on the foregoing embodiments, in other embodiments of this disclosure, one or more flows of the PDSCH or PUSCH corresponding to the first signal correspond to one or more first REs, and one or more flows of the PDSCH or PUSCH corresponding to the first signal correspond to one or more ports of the first signal corresponding to the first RE.

[0120] In this embodiment of the disclosure, one or more streams of the PDSCH corresponding to the first signal correspond to one or more first REs, that is, one or more streams of the PDSCH corresponding to the first signal are used to transmit the one or more first REs, and correspondingly, one or more streams of the PUSCH corresponding to the first signal are used to transmit the one or more first REs.

[0121] One or more streams of the PDSCH corresponding to the first signal have a corresponding relationship with the port of the first signal, wherein the port of the first signal is used to transmit one or more streams of the PDSCH corresponding to the first signal, and correspondingly, the port of the first signal is used to transmit one or more streams of the PUSCH corresponding to the first signal.

[0122] For example, when a reference signal such as CSI-RS collides or overlaps with the first signal SIP, the following example uses CSI-RS as the reference signal for transmission collision. When the first signal is transmitted in the first mode, one application scenario can be implemented by reducing the number of PDSCH or PUSCH streams corresponding to the SIP. This can be achieved by: when at least one RE in the transmission of SIP and CSI-RS overlaps, the reference signal and PDSCH / PUSCH of at least one layer corresponding to the overlapping SIP are not transmitted. For example, if SIP is used for 4-stream (l0, l1, l2, l3) PDSCH transmission, where at least one RE corresponding to l2 and l3 overlaps with CSI-RS, then the PDSCH for transmitting SIP becomes transmission of two streams, l0 and l1. At the same time, the streams l2 and l3 that originally corresponded to transmitting SIP and CSI-RS are not transmitted, and CSI-RS is also not transmitted.

[0123] Another application scenario can be implemented as follows: In Multi-User Multiple-Input Multiple-Output (MU-MIMO) mode, if overlapping or colliding REs are occupied by the SIPs of at least one UE, then the reference signals and PDSCH / PUSCH of at least one layer corresponding to the SIPs of these at least one UE will not be transmitted. For example, if UE1's SIP1 uses 2 ports to transmit 2 streams of PDSCH, and UE2's SIP2 uses 3 ports to transmit 3 streams of PDSCH, and CSI-RS overlaps with the PDSCHs of both UE1 and UE2, specifically overlapping with the SIP of UE1 corresponding to l1 and the SIP of UE2 corresponding to {l0, l1}, then UE1's PDSCH becomes a 1-stream transmission (l0), and UE2's PDSCH becomes a 1-stream transmission (l3). It should be noted that in MU-MIMO mode, UE1 corresponding to this SIP and at least one other UE (denoted as {UE2,…,UEn}) are co-scheduled, and {UE2,…,UEn} also receive or send SIPs to associate PDSCH / PUSCH, and the PDSCH / PUSCH of UE1 and the PDSCH / PUSCH of {UE2,…,UEn} occupy the same resources; the SIP of UE1 and the SIP of {UE2,…,UEn} occupy the same resources, or the resources occupied by any two UEs are different.

[0124] Based on the foregoing embodiments, in other embodiments of this disclosure, when the sending method is the second method, the second method includes at least one of the following:

[0125] Do not send the first signal on one or more sets of REs to which one or more first REs belong;

[0126] When one or more first REs are part of a set of one or more corresponding REs, the first signal is not sent on one or more first REs.

[0127] In this embodiment of the disclosure, when the transmission mode is the second mode, one or more first REs do not transmit the first signal, but may transmit a reference signal.

[0128] When the transmission mode is the second mode, one or more sets of REs to which one or more first REs belong are determined, which can also be called RE groups. In this case, when one or more first REs are used to transmit the first signal and the reference signal at the same time, the determined set of one or more REs can be used to transmit the reference signal, but does not transmit the first signal.

[0129] When one or more first REs are part of a set of one or more REs, no first signal is transmitted on the one or more first REs, but a reference signal may be transmitted.

[0130] Based on the foregoing embodiments, in other embodiments of this disclosure, some REs correspond to predefined sequences.

[0131] In this embodiment of the disclosure, the predefined sequence refers to a set of specific resource sequences that have been predetermined. In practical application scenarios, the predefined sequence can be set according to the actual situation. The correspondence between some REs and the predefined sequence can mean that some REs are specified REs in the predefined sequence.

[0132] Based on the foregoing embodiments, in other embodiments of this disclosure, the RE set satisfies at least one of the following conditions:

[0133] The RE set belongs to the same Code Division Multiplexing Group (CDM Group);

[0134] The RE set includes RE elements that correspond to predefined sequences.

[0135] In this embodiment of the disclosure, the correspondence between the RE elements included in the RE set and the predefined sequence can mean that the RE elements included in the RE set have the same length as the predefined sequence and correspond one-to-one.

[0136] Based on the foregoing embodiments, in other embodiments of this disclosure, the number of RE elements included in the RE set is the same as the length of the predefined sequence; and / or,

[0137] The elements in the predefined sequence are +1, -1, +j, -j, One of the values.

[0138] In this embodiment of the disclosure, when the transmission mode is the second mode, the number of PDSCH or PUSCH streams corresponding to SIP remains unchanged, but SIP on the overlapping RE and the PDSCH / PUSCH corresponding to SIP are not transmitted, but the overlapping CSI-RS can be transmitted.

[0139] Correspondingly, one application scenario could be: if one or more overlapping REs belong to a RE group corresponding to the SIP, then all REs in this RE group will not send SIP, but will instead send the overlapping CSI-RS. Wherein,

[0140] A RE group can be a CDM group, where the REs in this group are bound to a specific set of sequences, and the number of REs in this group is equal to the length of the specific sequence. For example, each element in the specific sequence can be +1, -1, +j, -j, ... Any of the following can be used. It should be noted that φ is a specific value, an empirical value set based on a large number of experiments or actual situations, and is not specifically limited here. In some application scenarios, a RE group can also be a group of REs with a relationship.

[0141] Correspondingly, another application scenario is as follows: when the following conditions are met, only on one or more overlapping REs, the overlapping SIP and the corresponding PDSCH / PUSCH are not sent. The corresponding conditions are: the overlapping one or more REs are part of the aforementioned RE group, or the part of the overlapping one or more REs correspond to one or more specific sequences in a set of sequences as defined above. This sequence ensures that even if the overlapping RE is not sent, the orthogonality within the RE group is not affected.

[0142] Based on the foregoing embodiments, in other embodiments of this disclosure, when the sending method is a third method, the third method includes:

[0143] Send one or more first signals corresponding to the first RE on the first resource or one or more second REs.

[0144] In this embodiment of the disclosure, the third approach is to select other REs to transmit the first signal. One or more second REs are REs different from the RE transmitting the first signal; that is, one or more second REs are different from one or more first REs, and also different from non-overlapping REs transmitting signals of the same type as the first signal. These can be pre-configured. The first resource is another PDSCH / PUSCH that is different from the PDSCH / PUSC corresponding to the first signal. In some application scenarios, the number of one or more second REs can be the same as the number of one or more first REs.

[0145] Based on the foregoing embodiments, in other embodiments of this disclosure, based on a first predefined rule and / or a first high-level configuration, a first resource or one or more second REs are one or more configured third REs, or a subset of one or more configured third REs.

[0146] In this embodiment of the disclosure, one or more third REs are pre-configured as REs for transmitting a first signal of overlap or collision. Then, according to a first predefined rule and / or a first higher layer configuration, a first resource or one or more second REs that can transmit the first signal of overlap or collision is selected from the one or more third REs so that the first signal of overlap or collision is transmitted through the first resource or one or more second REs. At this time, the first resource or one or more second REs can be the corresponding one or more third REs, or a subset of one or more third REs.

[0147] Based on the foregoing embodiments, in other embodiments of this disclosure, based on the transmission type of the first signal and / or, collision or overlap, a first resource or one or more second REs are determined or indicated according to a second predefined rule and / or a second higher-layer configuration.

[0148] In this embodiment of the disclosure, the transmission type of the first signal can be a mode for transmitting the first signal. Collision or overlap can refer to the proportion of one or more first REs simultaneously transmitting the first signal and a reference signal within all REs transmitting signals of the same type as the first signal, or within all REs transmitting the reference signal, or within all REs transmitting signals of the same type as the first signal. When the first resource or one or more second REs are determined to be obtained, it can be indicated to the transmitting device by the receiving device or other devices after determining the first resource or one or more second REs based on the transmission type of the first signal, and / or the collision or overlap situation, according to a second predefined rule and / or a second higher-layer configuration.

[0149] Based on the foregoing embodiments, in other embodiments of this disclosure, the first resource or one or more second REs include one or more of the following information:

[0150] The symbol position within a time slot;

[0151] RE location within a resource block RB;

[0152] cycle;

[0153] Time slot offset;

[0154] Occupied RB position;

[0155] Time domain and frequency domain density;

[0156] Bandwidth used.

[0157] In this embodiment of the disclosure, when the transmission method is the third method, the number of PDSCH or PUSCH streams corresponding to the SIP remains unchanged. However, SIP is not transmitted on one or more overlapping REs, but CSI-RS is transmitted. Furthermore, the SIP and data on the one or more overlapping REs are selected to be transmitted on other REs. These other REs do not belong to the one or more overlapping REs, nor to the REs originally occupied by the non-overlapping SIP. One implementation of selecting other REs is as follows: the base station can configure several reserve REs. When the REs for the SIP overlap, the other RE is selected from the several reserve REs according to predefined rules and / or base station configuration. Another implementation of selecting other REs is as follows: the base station can configure one or more alternative transmission patterns for the SIP. Based on the transmission type of the SIP and its overlap with other reference signals, the base station selects one alternative transmission pattern from the one or more alternative transmission patterns for the SIP according to predefined rules and / or base station configuration, and transmits the overlapping SIP to the UE based on the selected alternative transmission pattern. Correspondingly, the alternative transmission mode can be implemented through at least one of the following modes: the symbol position of SIP transmission within a slot; the RE position of SIP transmission within an RB; the SIP transmission period; the SIP transmission time slot offset; the RB position occupied by SIP; the time domain and frequency domain density of SIP; the bandwidth occupied by SIP, etc.

[0158] Based on the foregoing embodiments, in other embodiments of this disclosure, the method of transmitting the first signal may be determined or indicated based on the device capabilities of the terminal device.

[0159] In this embodiment of the disclosure, when the sending device is a network device, the device capabilities of the terminal device can be those reported by the terminal device to the network device. For example, the terminal device's capabilities can include supporting a first mode, a second mode, or a third mode; that is, it can be a transmission mode that the terminal device supports, or the ability to receive a first signal transmitted by the network device and process the received signal accordingly. When the transmission mode of the first signal is indicative, it can be achieved by the receiving device determining the transmission mode of the first signal based on its own device capabilities and then instructing the sending device accordingly.

[0160] Based on the foregoing embodiments, in other embodiments of this disclosure, the transmission method of the first signal is determined or indicated according to the proportion of one or more first REs in all REs occupied by the first signal.

[0161] In this embodiment of the disclosure, a first number of one or more first REs is counted, a second number of all REs occupied by signals of the same type as the first signal is counted, and the ratio of the first number to the second number is calculated to obtain a percentage. Based on this percentage, a corresponding transmission method is selected. For example, if the percentage is within a first percentage range, the transmission method is determined to be the first method; if the percentage is within a second percentage range, the transmission method is determined to be the second method; and if the percentage is within a third percentage range, the transmission method is determined to be the third method. This determination process can be implemented through pre-configuration. When the transmission method of the first signal is indicated, it can be implemented by the receiving device determining the transmission method of the first signal based on the percentage of one or more first REs in the total number of REs occupied by the first signal, and then instructing the transmitting device accordingly.

[0162] Based on the foregoing embodiments, in other embodiments of this disclosure, the transmission method of the first signal is determined or indicated according to the proportion of one or more first REs in all REs occupied by the first signal, which can be achieved through the following steps:

[0163] Based on the relationship between the percentage and the preset threshold, the sending method is determined or indicated.

[0164] In this embodiment, the preset threshold can be a predetermined empirical value or a value determined based on the actual state parameters of the terminal device, etc. The specific choice depends on the actual application scenario and is not specifically limited here. Indicating the transmission method can involve instructing the receiving device on the transmission method so that the receiving device can subsequently process the received first signal accordingly.

[0165] Based on the foregoing embodiments, in other embodiments of this disclosure, the method further includes the following steps:

[0166] A preset threshold is determined based on at least one of the following: the device capabilities of the terminal device, the higher-layer parameters of the network device configuration, the resource type of the first signal, the downlink control information (DCI) and the time interval between its scheduled physical downlink shared channel (PDSCH) / physical uplink shared channel (PUSCH).

[0167] Based on the foregoing embodiments, in other embodiments of this disclosure, the transmitting device includes a terminal device or a network device.

[0168] In this embodiment of the disclosure, when the sending device is a terminal device, the receiving device is usually a network device. If the sending device is a network device, the corresponding receiving device is usually a terminal device.

[0169] For example, when selecting which transmission method to use, the terminal equipment (User Equipment, UE) can report through its UE capabilities that it supports one or more of the first, second, or third methods. Alternatively, the UE capability can be further configured by the base station through higher layers to indicate to the UE which one or more methods it can use, or that the UE does not support any of them.

[0170] Another implementation process for selecting the transmission method can be as follows: The method is determined based on the proportion of one or more overlapping REs in the total REs occupied by overlapping and non-overlapping SIPs. For example, when the proportion is greater than, or greater than or equal to, a certain threshold, the first and third methods are selected; otherwise, method 2 is selected. It should be noted that in some application scenarios, this threshold can be determined by at least one of the following: terminal capabilities, higher-layer parameters configured by the base station, SIP resource type, and the time interval between the DCI and its scheduled PDSCH / PUSCH.

[0171] The signal transmission method provided in this disclosure involves, if a first signal collides or overlaps with a reference signal, the transmitting device determines the transmission mode of the first signal and transmits a transmission signal related to the first signal transmitted in that mode, so that the receiving device receives the transmission signal transmitted by the transmitting device. In this way, when the first signal collides or overlaps with the reference signal, the transmitting device processes the first signal using the transmission mode corresponding to the first signal, so that the receiving device receives the corresponding transmission signal. This achieves dynamic adjustment of the transmission of colliding or overlapping signals, solving the problem of resource waste caused by changes in uplink data during current uplink data transmission. It proposes an information processing method that enables the configuration of semi-static resources according to actual conditions, reducing the possibility of resource waste and improving resource utilization.
