Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to transmission methods and apparatus in wireless communication systems where DMRS and signals overlap. Background Technology

[0002] In traditional wireless communication, the DMRS (Demodulation Reference Signal) and the PUSCH (Physical Uplink Shared Channel) carrying uplink transmission information are strictly orthogonal in the time and frequency domains, meaning they occupy different REs (Resource Elements). This orthogonal design can reduce the complexity of the receiver (especially reducing the difficulty of estimating the PUSCH channel), but it will lead to the problem of inefficient resource utilization.

[0003] In the evolution from 5G to 6G, the integration of AI (Artificial Intelligence) / ML (Machine Learning) with wireless communication technology is a trend, and the application of AI / ML in wireless communication systems has received increasing attention and discussion.

[0004] By utilizing intelligent signal processing techniques (such as AI / ML-based channel estimation, AI / ML-based receivers, etc.) for interference suppression and signal separation, non-orthogonal transmission of DMRS and PUSCH (e.g., allowing both to overlap on the same RE) is a potential solution to improve resource utilization. Summary of the Invention

[0005] When considering the overlap between DMRS and uplink signals, the design of UCI (Uplink Control Information) transmission becomes a worthwhile research issue in system optimization. This application discloses a solution to the aforementioned problem. It should be noted that while the motivation for this application primarily stems from scenarios involving interference suppression and signal separation using intelligent signal processing technologies (such as AI / ML-based channel estimation and AI / ML-based receivers), this application is also applicable to scenarios involving interference suppression and signal separation using traditional signal processing technologies (such as minimum mean square error-based channel estimation and Turbo iterative algorithm-based receivers), achieving similar technical effects. Furthermore, adopting a unified solution across different scenarios helps reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0006] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the TS38 series of specification protocols of 3GPP (3rd Generation Partner Project).

[0007] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0008] Receive a first signaling message, the first signaling message indicating at least a first resource set;

[0009] Send a first DMRS and a first signal in the first resource set, wherein the first signal carries uplink transmission information;

[0010] The overlap between the first DMRS and the first signal transmitted in the first resource set is dependent on whether the first UCI is transmitted on a resource in the first resource set; the first UCI includes at least HARQ-ACK information.

[0011] As an example, the problems to be solved by this application include: how the overlap between DMRS and uplink signals affects the transmission of UCI, or how the transmission of UCI affects the overlap between DMRS and uplink signals.

[0012] As one embodiment, whether the first UCI is transmitted on resources in the first resource set depends on the overlap between the first DMRS and the first signal transmitted in the first resource set;

[0013] The above method provides the possibility of optimizing UCI transmission based on resource overlap, which is conducive to improving UCI transmission performance by utilizing reasonable resource allocation.

[0014] As an example, the overlap between the first DMRS and the first signal transmitted in the first resource set depends on whether the first UCI is transmitted on a resource in the first resource set;

[0015] The above method is beneficial for adjusting resource overlap according to the transmission requirements of UCI, enhancing the system's flexibility in responding to different scenarios and service needs. For example, when it is necessary to send UCI including HARQ-ACK information, the overlap of DMRS and this type of UCI can be avoided by adjusting the resource overlap. Furthermore, when it is necessary to send UCI including CSI, the overlap of DMRS and this type of UCI can be supported by adjusting the resource overlap.

[0016] As an example, the above method adjusts the overlap between DMRS and uplink signals based on the presence of UCI, which can make more efficient use of resources and thus improve resource utilization.

[0017] As one example, the first node is a user equipment.

[0018] As an example, the first node is a relay node.

[0019] As one example, the first node is a terminal.

[0020] According to one aspect of this application, the above method is characterized in that,

[0021] The target resource is a resource in the first resource set, and whether the target resource belongs to the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal depends on whether the target resource is used to transmit the first UCI.

[0022] As an example, the above method maps UCI to non-overlapping resources, reduces the interference of DMRS on UCI transmission, and ensures the reliability of UCI transmission.

[0023] According to one aspect of this application, the above method is characterized in that,

[0024] The target resource is a resource in the first resource set; when the target resource belongs to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set, the target resource is not used to transmit the first UCI; when the target resource does not belong to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set, the target resource is used to transmit the first UCI.

[0025] As an example, the above method avoids UCI transmission on overlapping resources, reduces DMRS interference to UCI transmission, and ensures the reliability of UCI transmission.

[0026] According to one aspect of this application, the above method is characterized in that,

[0027] The first resource set includes multiple REs in the time-frequency domain, and the target RE is one of the multiple REs; the allocation between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on the target RE depends on whether the first UCI is transmitted on the target RE.

[0028] As an example, the above method adjusts the power allocation between the first DMRS and the first signal based on whether the RE is used for UCI transmission, ensuring that the signal carrying UCI is allocated more power and improving the reliability of UCI transmission.

[0029] According to one aspect of this application, the above method is characterized in that,

[0030] When the target RE is used to transmit the first UCI, the ratio between the power used for the transmission of the first DMRS on the target RE and the power used for the transmission of the first signal is not greater than a first threshold.

[0031] The first threshold is either predefined or configurable.

[0035] Wherein, the first ratio and the second ratio are predefined or configurable, and the first ratio is not greater than the second ratio.

[0036] As an example, the above method configures two different ratios based on whether the first UCI is transmitted, thereby improving the accuracy of power allocation / control and reducing interference.

[0037] According to one aspect of this application, the above method is characterized by comprising:

[0195] As an example, the target resource is a resource in the first resource set; when the target resource is used to transmit the first UCI, the target resource does not belong to the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal.

[0197] As an example, the relationship between the ratio of the power used for the transmission of the first DMRS to the power used for the transmission of the first signal on a resource in the first resource set and a threshold depends on whether the first UCI is transmitted on that resource.

[0198] As an example, the ratio between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on a resource in the first resource set depends on whether the first UCI is transmitted on that resource.

[0199] As one embodiment, the overlap between the first DMRS and the first signal transmitted in the first resource set is dependent on whether the first UCI is transmitted on a resource in the first resource set, including: the target resource is a resource in the first resource set, and whether the target resource is used to transmit the first UCI depends on whether the target resource belongs to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set.

[0200] As an example, the target resource is a resource in the first resource set; when the target resource belongs to the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal, the target resource is not used to transmit the first UCI.

[0206] As an example, whether a resource in the first resource set is used to transmit the first UCI depends on the allocation between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on that resource.

[0207] As an example, whether a resource in the first resource set is used to transmit the first UCI depends on the magnitude of the ratio between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on that resource and a threshold.

[0208] As an example, the target resource is a resource in the first resource set used for the transmission of the first signal; whether the first UCI is transmitted on the target resource depends on whether there is an overlap between the resources in the first resource set used for the transmission of the first DMRS and the target resource.

[0210] As an example, the target resource is the resource in the first resource set used for the transmission of the first signal; when there is an overlap between the resource in the first resource set used for the transmission of the first DMRS and the target resource, the first UCI will not transmit on the target resource; when there is no overlap between the resource in the first resource set used for the transmission of the first DMRS and the target resource, the first UCI can transmit on the target resource.

[0211] As an example, the first UCI is not mapped to resources in the first resource set used for the transmission of the first DMRS, but is mapped to resources in the first resource set not used for the transmission of the first DMRS.

[0245] Example 3

[0246] Example 3 illustrates a schematic diagram of the radio protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown.

[0247] Appendix Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300, with appended... Figure 3The radio protocol architecture for control plane 300 is illustrated using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the links between the first and second communication node devices and between the two UEs via PHY301. L2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and provides cross-area mobility support. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception caused by HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell. MAC sublayer 302 is also responsible for HARQ operations.

The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). In user plane 350, the radio protocol architecture for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355 is largely the same as the corresponding layers and sublayers in control plane 300. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and data radio bearers (DRBs) to support service diversity.Although not illustrated, the user node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0259] Example 4

[0260] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0261] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0262] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0263] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In DL (Downlink), the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for L1 layer (i.e., physical layer). Transmit processor 416 performs channel coding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more... Parallel streams. Transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by multi-antenna transmit processor 471 into an RF stream, which is then provided to different antennas 420.

[0264] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, physical layer data information and reference signals are demultiplexed by the receiver processor 456, where the reference signals are used for channel estimation, and the data information is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted over the physical channel by the first communication device 410. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2 (L2). The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0265] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0266] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0281] Example 5

[0282] Example 5 illustrates a transmission flowchart between a first node and a second node according to an embodiment of this application, as shown in the attached diagram. Figure 5 As shown. In particular, the steps in the dashed box F51 are optional. It should be noted that the order in this embodiment does not limit the signal transmission order or the order of implementation in this application.

[0283] First node U1 receives a first information block in step S51A; receives a first signaling in step S510; and sends a first DMRS and a first signal in the first resource set in step S511.

[0284] The second node U2 sends a first information block in step S52A; sends a first signaling in step S520; and receives a first DMRS and a first signal in the first resource set in step S521.

[0285] In Embodiment 5, the first signaling at least indicates a first resource set; the first signal carries uplink transmission information; there is a dependency between the overlap between the first DMRS and the first signal transmitted in the first resource set and whether the first UCI is transmitted on a resource in the first resource set; the first UCI includes at least HARQ-ACK information.

[0286] The first resource set includes multiple REs in the time-frequency domain, and the target RE is one of the multiple REs; the allocation between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on the target RE depends on whether the first UCI is transmitted on the target RE.

[0287] As a sub-implementation of Embodiment 5, the target resource is a resource in the first resource set, and whether the target resource belongs to the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal depends on whether the target resource is used to transmit the first UCI.

[0288] As a sub-implementation of Embodiment 5, the target resource is a resource in the first resource set; when the target resource belongs to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set, the target resource is not used to transmit the first UCI; when the target resource does not belong to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set, the target resource is used to transmit the first UCI.

[0289] As a sub-example of Example 5, when the target RE is used to transmit the first UCI, the ratio between the power used for the transmission of the first DMRS on the target RE and the power used for the transmission of the first signal is not greater than a first threshold; wherein the first threshold is predefined or configurable.

[0290] As a sub-example of Embodiment 5, when the target RE is used to transmit the first UCI, the ratio between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on the target RE is equal to a first ratio; when the target resource is not used to transmit the first UCI, the ratio between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on the target RE is equal to a second ratio; wherein, the first ratio and the second ratio are predefined or configurable, and the first ratio is not greater than the second ratio.

[0291] As an example, the first node U1 is the first node in this application.

[0292] As an example, the second node U2 is the second node in this application.

[0293] As an example, the first node U1 is a UE.

[0294] As one example, the second node U2 is a base station.

[0295] As one embodiment, the air interface between the second node U2 and the first node U1 is the Uu interface.

[0296] As one embodiment, the air interface between the second node U2 and the first node U1 includes a cellular link.

[0297] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between the base station equipment and the user equipment.

[0298] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between the relay device and the user equipment.

[0299] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between user equipment and user equipment.

[0300] As one embodiment, the second node U2 is the serving cell sustaining base station of the first node U1.

[0301] As an example, the step in the dashed box F51 includes the first information block indicating a first ratio set; wherein the first ratio set includes at least two ratios, and the unit of each ratio in the first ratio set is dB.

[0302] As one embodiment, the first information block is carried by physical layer signaling.

[0303] As an example, the first information block is a DCI format for scheduling the first signal.

[0304] As one embodiment, the first information block includes higher layer parameters.

[0305] As an example, the first information block is a MAC CE (Medium Access Control layer Control Element).

[0306] As an embodiment, the first information block is carried by RRC (Radio Resource Control) signaling.

[0307] As an embodiment, the first information block is transmitted / received before the first signaling.

[0308] As an embodiment, the first information block is transmitted / received after the first signaling.

[0309] As an embodiment, the first information block is transmitted / received simultaneously with the first signaling.

[0310] As an embodiment, the step in the dashed box F51 does not exist, and the first signaling indicates a first ratio set; wherein the first ratio set includes at least two ratios, and the unit of each ratio in the first ratio set is dB.

[0311] As an embodiment, the step in the dashed box F51 does not exist, and the first ratio set is predefined.

[0312] As an embodiment, the first ratio set includes at least two ratios, each ratio in the first ratio set is predefined, and the unit of each ratio in the first ratio set is dB.

[0313] As an embodiment, the receiving processing of the second node on at least one of the first DMRS and the first signal is based on AI; the receiving processing of the second node on at least one of the first DMRS and the first signal includes at least one of channel estimation, channel equalization, demapping, and decoding.

[0314] As an embodiment, the channel estimation of the second node on the first DMRS is based on AI.

[0315] As an embodiment, the second node recovers uplink transmission information carried by the first signal from the received first DMRS and the first signal based on AI; or, at least one of channel equalization, demapping, and decoding of the first signal by the second node is based on AI.

[0316] In the above method, the AI includes ML (Machine Learning).

[0317] Compared to existing communication systems where the REs occupied by DMRS and the REs occupied by the signal carrying uplink transmission information are orthogonal, the above method has significant advantages because DMRS and uplink transmission information can be mapped to the same RE. For example, it improves resource utilization, spectrum efficiency, and uplink throughput. In addition, the use of intelligent signal processing technology (such as AI / ML-based channel estimation and AI / ML-based receivers) improves the accuracy of channel estimation on DMRS and enhances the reliability of information transmission.

[0318] In the above method, the reception processing of at least one of the first DMRS and the first signal by the second node is implementation-dependent, i.e., determined by the hardware equipment vendor of the second node; several typical but non-limiting implementations are described below:

[0319] In one implementation, the second node estimates the channel matrix based on the first DMRS. Then, the second node demultiplexes the first DMRS and the first signal, and performs channel equalization, demapping, and decoding on the demultiplexed first signal to recover the uplink transmission information carried by the first signal.

[0320] The second node estimates the channel matrix based on the first DMRS. This can be a traditional channel estimation algorithm or an AI-based algorithm (for example, the second node inputs the received first DMRS, the first signal, and the DMRS sequence into an AI model, and the output of the AI ​​model is used to obtain the estimated channel matrix).

[0321] The second node can recover the uplink transmission information carried by the first signal based on traditional (i.e., non-AI) algorithms, or it can be based entirely on AI, or it can be based partially on AI (i.e., a combination of AI and non-AI).

[0322] The demultiplexed first signal and the estimated channel matrix are input into the AI ​​model, and the output of the AI ​​model is used to recover the uplink transmission information carried by the first signal.

[0323] The above-mentioned channel estimation and uplink transmission information recovery process can be iterated multiple times to improve the accuracy of channel estimation and the accuracy of uplink transmission information recovery.

[0324] The structure and parameters of the AI ​​model in the above embodiments are known to the second node. For example, they may be obtained by downloading from a network device, or they may be specified in a standard, or they may be implementation-related to the second node (i.e., determined by the hardware device vendor of the second node).

[0326] Examples 6A-6B illustrate schematic diagrams of resources in a first resource set for the transmission of a first DMRS and a first signal according to an embodiment of this application, as shown in the attached diagrams. Figures 6A-6B As shown.

[0327] In embodiment 6A, the first resource set includes resources for transmitting the first DMRS and resources for transmitting the first signal, wherein the resources for transmitting the first DMRS and the resources for transmitting the first signal in the first resource set do not overlap.

[0328] In the appendix Figure 6A In the above, each rectangle represents a resource in the first resource set, each diagonally filled rectangle represents a resource in the first resource set used only for transmitting the first DMRS, and each dot matrix filled rectangle represents a resource in the first resource set used only for transmitting the first signal.

[0329] As an example, the first DMRS and the first signal do not overlap in the first resource set.

[0330] As an example, in the first resource set, the first DMRS and the first signal do not overlap in the time domain, or the first DMRS and the first signal do not overlap in the frequency domain.

[0331] As an example, there is no overlap between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal.

[0332] As an example, there is no resource in the first resource set that is used for both transmitting the first DMRS and transmitting the first signal.

[0333] As an example, the first DMRS and the first signal are mapped to different resources in the first resource set.

[0334] As one embodiment, the first DMRS and the first signal are mapped to different REs in the first resource set.

[0335] As an example, there is no resource in the first resource set that is used for both the transmission of the first DMRS and the transmission of the first signal.

[0336] As an example, there is no RE in the first resource set that is both the RE used for the transmission of the first DMRS and the RE used for the transmission of the first signal.

[0337] As an example, when the first DMRS / the first signal is transmitted on a resource in the first resource set, the resource in the first resource set is a resource used for transmitting the first DMRS / the first signal.

[0338] As an example, when the first DMRS is transmitted on a resource in the first resource set, and the first signal is not transmitted on that resource in the first resource set, that resource in the first resource set only transmits the first DMRS.

[0339] As an example, when the first signal is transmitted on a resource in the first resource set, and the first DMRS is not transmitted on that resource in the first resource set, the resource in the first resource set only transmits the first signal.

[0340] In embodiment 6B, the first resource set includes resources for transmitting the first DMRS and resources for transmitting the first signal, wherein the resources for transmitting the first DMRS and the resources for transmitting the first signal overlap in the first resource set.

[0341] In the appendix Figure 6B In the above, each rectangle represents a resource in the first resource set, each diagonally filled rectangle represents a resource in the first resource set used for transmitting only the first DMRS, each dot matrix filled rectangle represents a resource in the first resource set used for transmitting only the first signal, and each large outline diamond filled rectangle represents a resource in the first resource set used for transmitting both the first DMRS and the first signal.

[0342] As an example, in the first resource set, the first DMRS at least partially overlaps with the first signal.

[0343] As one embodiment, the first DMRS and the first signal partially or fully overlap in the time domain, and the first DMRS and the first signal partially or fully overlap in the frequency domain.

[0344] As one embodiment, there is an overlap between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal.

[0345] As an example, the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal is used for transmitting the first DMRS and the first signal.

[0346] As an example, the overlapping portion of the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal is used for both the transmission of the first DMRS and the transmission of the first signal.

[0347] As an example, when both the first DMRS and the first signal are mapped to a resource in the first resource set, this resource in the first resource set belongs to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal.

[0348] As an example, when both the first DMRS and the first signal are mapped to a RE in the first resource set, this RE in the first resource set belongs to the overlapping portion between the RE set used for the transmission of the first DMRS and the RE set used for the transmission of the first signal.

[0349] As an example, when a resource in the first resource set is both a resource for the transmission of the first DMRS and a resource for the transmission of the first signal, the resource in the first resource set belongs to the overlapping portion between the resource for the transmission of the first DMRS and the resource for the transmission of the first signal.

[0350] As an example, when a RE in the first resource set is both a RE for the transmission of the first DMRS and a RE for the transmission of the first signal, this RE in the first resource set belongs to the overlapping portion between the RE set for the transmission of the first DMRS and the RE set for the transmission of the first signal.

[0351] As an example, when the first DMRS / the first signal is transmitted on a resource in the first resource set, the resource in the first resource set is a resource used for transmitting the first DMRS / the first signal.

[0352] As an example, when the first DMRS is transmitted on a resource in the first resource set, and the first signal is not transmitted on that resource in the first resource set, that resource in the first resource set only transmits the first DMRS.

[0353] As an example, when the first signal is transmitted on a resource in the first resource set, and the first DMRS is not transmitted on that resource in the first resource set, the resource in the first resource set only transmits the first signal.

[0357] As an example, in the above method, whether the target resource belongs to the overlapping part between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set depends on whether the target resource is used to transmit the first UCI. Mapping the first UCI to non-overlapping resources reduces the interference of the first DMRS on the transmission of the first UCI and ensures the transmission reliability of the first UCI.

[0358] As an example, the target resource is any resource in the first resource set.

[0359] As an example, at least the HARQ-ACK information belongs to the first UCI.

[0360] As an example, the HARQ-ACK information and CSI part 1 belong to the first UCI.

[0361] As an example, the HARQ-ACK information, CSI part 1, and CSI part 2 belong to the first UCI.

[0362] As an example, when the target resource is used to transmit the first UCI, the target resource will not belong to the overlapping portion between the resources used for the transmission of the first DMRS and the resources used for the transmission of the first signal in the first resource set.

[0363] As an example, when the target resource is used to transmit the first UCI, the first node does not expect the target resource to belong to the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal.

[0409] In embodiments 9A-9B, the first resource set includes multiple REs in the time-frequency domain, and the first DMRS and the first signal are transmitted on the multiple REs.

[0410] As an example, the target RE is one of the plurality of REs; the allocation between the power used for the transmission of the first DMRS and the power used for the transmission of the first signal on the target RE depends on whether the first UCI is transmitted on the target RE.

[0411] As an example, the sum of the power used for the transmission of the first DMRS on the target RE and the power used for the transmission of the first signal is the EPRE (Energy Per Resource Element) on the target RE.

[0430] As a sub-implementation of the above embodiment, the second component is 10log 10 (2 μ ·M); wherein, the 2 μ The value is equal to the subcarrier spacing (in kHz) of the first resource set divided by 15 kHz, where M is the bandwidth of the first resource set, which is the number of RBs occupied by the first resource set in the frequency domain.

[0638] The overlap between the first DMRS and the first signal transmitted in the first resource set is dependent on whether the first UCI is transmitted on a resource in the first resource set; the first UCI includes at least HARQ-ACK information.

[0639] As an example, the target resource is a resource in the first resource set, and whether the target resource belongs to the overlapping portion between the resources in the first resource set used for the transmission of the first DMRS and the resources used for the transmission of the first signal depends on whether the target resource is used to transmit the first UCI.
