Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for resource mapping. Background Technology

[0002] To improve scheduling efficiency and reduce downlink control information (DCI) overhead, new radio (NR) technology introduces a multi-slot physical uplink shared channel (PUSCH) and a multi-slot physical downlink shared channel (PDSCH). This means that a DCI schedules at least one PDSCH across multiple consecutive time slots, or a DCI schedules at least one PUSCH across multiple consecutive time slots.

[0003] In high-frequency communication systems, beamforming technology is introduced, where different beams can be considered as different resources. Different beams can transmit the same or different information. A single beam can be used to transmit data channels, control channels, and probe signals. For example, the transmit beam refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receive beam refers to the distribution of signal strength in different directions in space received from the antenna. When using high-frequency bands, thanks to the smaller carrier wavelength of high-frequency communication systems, antenna arrays consisting of many antenna elements can be arranged at both the transmitting and receiving ends. The transmitting end transmits signals with a certain beamforming weight, forming a spatially directional beam. Simultaneously, at the receiving end, an antenna array with a certain beamforming weight is used for reception, which can improve the received signal power and counteract path loss.

[0004] When terminal or network devices need to switch beams, switching delays are introduced. When the sub-carrier spacing (SCS) is particularly large, the length of its time unit is relatively short, and the switching time will occupy multiple time units. Furthermore, PDSCH or PUSCH cannot be transmitted during beam switching, thus affecting the reception performance of network or terminal devices. Summary of the Invention

[0005] This application provides a resource mapping method and apparatus for scheduling data channels in multiple time units, aiming to ensure that the receiving end device and the transmitting end device have a consistent understanding of the resource mapping, thereby improving the receiving performance.

[0006] In a first aspect, a method for resource mapping is provided, comprising: mapping symbols in a first resource, excluding at least one first symbol, to a first data channel; and / or mapping symbols in a second resource, excluding at least one first symbol, to a second data channel; wherein the beams corresponding to the first data channel and the second data channel are different; the first resource and the second resource include M second symbols, which are symbols not mapped to either the first data channel or the second data channel; the first symbols and the second symbols are adjacent; M is an integer and M≥0; the sum of the number of first symbols and the number of second symbols is equal to a first threshold; and transmitting signals on the first data channel and the second data channel.

[0007] In the above scheme, the sum of the number of first symbols and the number of second symbols equals a first threshold, and the first and second symbols are adjacent. The second symbols are symbols not mapped to the first data channel and / or the second data channel. If the beams corresponding to the first and second data channels are different, and the number of second symbols is less than the first threshold, it may lead to inconsistencies between the transmitting and receiving devices regarding which symbols the data channels should be mapped, thus reducing reception performance. Therefore, symbols in the first resource (excluding at least one first symbol) can be mapped to the first data channel, and / or symbols in the second resource (excluding at least one first symbol) can be mapped to the second data channel. This ensures consistency in the understanding of resource mapping between the transmitting and receiving devices, avoiding unnecessary resource waste.

[0008] It should be understood that the first data channel and the second data channel in the above scheme are scheduled sequentially in the time domain. That is, from the time domain perspective, the first data channel is sent at a time before the second data channel, or the first data channel is sent at a time after the second data channel. In addition, the first data channel and the second data channel can be in the same time unit or in different time units. This application does not impose any restrictions on this.

[0009] In conjunction with the first aspect, in some possible designs, the method further includes: mapping a reference signal onto the Nth symbol following the third symbol, the Nth symbol being determined based on the position of the symbol of the reference signal to be mapped, the third symbol including the first symbol and the second symbol, and N being a positive integer greater than or equal to 1; and transmitting the reference signal.

[0010] In some possible designs, the reference signal can be the demodulation reference signal DMRS.

[0011] In the above scheme, determining whether to map the reference signal after the third symbol based on the position of the reference signal to be mapped can effectively ensure that the transmitting and receiving devices have a consistent understanding of the mapping of the reference signal, avoid unnecessary waste of resources, and help improve channel estimation and reception performance.

[0012] In conjunction with the first aspect, in some possible designs, the symbol of the reference signal to be mapped overlaps with the third symbol; or, there is no symbol of the reference signal to be mapped on the second resource, wherein the second resource follows the first resource; or, the first resource follows the second resource, and there is no symbol of the reference signal to be mapped on the first resource.

[0013] In the above scheme, the determination of whether to map the reference signal in the Nth symbol after the third symbol can be made by checking whether the symbol of the reference signal to be mapped overlaps with the third symbol or whether the symbol of the reference signal to be mapped exists in the subsequent symbol to be mapped. In other words, if the symbol of the reference signal to be mapped overlaps with the third symbol, the symbol of the mapped reference signal is changed; or, if the symbol of the reference signal does not exist in the symbol to be mapped after beam switching, the symbol of the reference signal is added. This effectively ensures that the transmitting and receiving devices have a consistent understanding of the mapping of the reference signal, avoids unnecessary resource waste, and is beneficial for improving channel estimation and receiving performance.

[0014] In conjunction with the first aspect, in some possible designs, the method further includes: if the symbol of the first signal to be mapped overlaps with a third symbol, the first signal is not mapped onto the third symbol, the first signal including a set of control resources.

[0015] In the above scheme, if the symbol of the first signal to be mapped overlaps with the third symbol, the first signal is not mapped on the third symbol. This can effectively ensure that the transmitting and receiving devices have a consistent understanding of the mapping of the first signal, avoid unnecessary waste of resources, and help improve channel estimation and reception performance.

[0016] In conjunction with the first aspect, in some possible designs, the method further includes: switching from the beam corresponding to the first data channel to the beam corresponding to the second data channel at a beam-switching position, the beam-switching position being before the third symbol.

[0017] In the above scheme, the transmitting device begins beam switching at the beam switching position, which is before the third symbol. The beam switching position can also be the starting position of the first symbol of the third symbol; this application does not impose any restrictions. The proposed beam switching position in this application effectively ensures that the transmitting and receiving devices have a consistent understanding of the beam switching start position, avoiding unnecessary resource waste and improving reception performance.

[0018] In conjunction with the first aspect, in some possible designs, the first resource is determined according to the first resource indication information, and the second resource is determined according to the second resource indication information. The first resource indication information is used to indicate the symbol for mapping the first data channel, and the second resource indication information is used to indicate the symbol for mapping the second data channel. The value range of the first resource indication information is determined according to the first threshold, and the value range of the second resource indication information is determined according to the first threshold.

[0019] In some possible designs, the first resource indication information may be start and length indication information SLIV, and the second resource indication information may be start and length indication information SLIV, but this application does not limit this.

[0020] In some possible designs, the value range of the first resource indication information is determined according to a first threshold. Specifically, the value range of the starting S is determined according to the first threshold. For example, the starting S is not less than the first threshold. The same applies to the second resource indication information. This application does not impose any further limitations.

[0021] In the above scheme, the symbol to be mapped is determined based on resource indication information, which indicates the symbol of the data channel to be mapped. Alternatively, it can be understood that the indication information indicates the symbol of the data channel to be mapped. The value range of the indication information is determined based on a first threshold, which can avoid unnecessary resource waste and improve reception performance.

[0022] In conjunction with the first aspect, in some possible designs, the first data channel is the first physical downlink shared channel (PDSCH), and the second data channel is the second PDSCH; or, the first data channel is the first physical uplink shared channel (PUSCH), and the second data channel is the second PUSCH.

[0023] It should be understood that the first data channel and the second data channel should be data channels of the same type, that is, both should be PDSCH or both should be PUSCH. When both are PDSCH, the sending device can be a network device. When both are PUSCH, the sending device is a terminal device.

[0024] In conjunction with the first aspect, in some possible designs, when the first data channel is the first physical downlink shared channel (PDSCH), if the beam corresponding to the first PDSCH is the same as the first beam, the first PDSCH is mapped on the first resource.

[0025] In conjunction with the first aspect, in some possible designs, when the first data channel is the first physical downlink shared channel (PDSCH), if the beam corresponding to the first PDSCH is not the same as the first beam, the first PDSCH is not mapped on the first resource.

[0026] In the above scheme, determining whether to map the first PDSCH on the first resource based on whether the beam corresponding to the first PDSCH is the same as the first beam can avoid frequent beam switching. At the same time, it is beneficial for the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve receiving performance.

[0027] In conjunction with the first aspect, in some possible designs, the first beam is the second beam or the third beam, the second beam is the beam corresponding to the first indication information or a pre-configured beam, and the third beam is the beam corresponding to the first indication information, the beam indicated by the first indication information, or a pre-configured beam.

[0028] In conjunction with the first aspect, in some possible designs, before the end of the first duration, if the beam corresponding to the first PDSCH is the same as the first beam, mapping the first PDSCH on the first resource includes: if the beam corresponding to the first PDSCH is the same as the second beam, mapping the first PDSCH on the first resource; or, if the beam corresponding to the first PDSCH is different from the second beam, not mapping the first PDSCH on the first resource; wherein, the first duration is related to the processing time of the terminal device.

[0029] It should be understood that the first duration is related to the processing time of the terminal device, which can be understood as the terminal device determining the first duration. Specifically, the first duration is the sum of the time the terminal device processes the first indication information and the time used for beam switching, or the first duration is the time from when the terminal device receives the first indication information to when the beam switching ends.

[0030] In the above scheme, for the symbols to be mapped before the end of the first duration, the beam corresponding to the first PDSCH is compared with the second beam. If they are the same, the first PDSCH is mapped on the first resource; otherwise, the first PDSCH is not mapped on the first resource. This can avoid frequent beam switching and also help the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve receiving performance.

[0031] In conjunction with the first aspect, in some possible designs, after the end of the first duration, if the beam corresponding to the first PDSCH is the same as the first beam, mapping the first PDSCH on the first resource includes: if the first PDSCH has a high priority and the beam corresponding to the first PDSCH is the same as the third beam, mapping the first PDSCH on the first resource; or, if the first PDSCH has a high priority and the beam corresponding to the first PDSCH is different from the third beam, not mapping the first PDSCH on the first resource; wherein, the first duration is related to the processing time of the terminal device.

[0032] In the above scheme, for symbols to be mapped after the end of the first duration, the beam corresponding to the high-priority first PDSCH is compared with the second beam. If they are the same, the first PDSCH is mapped on the first resource; otherwise, it is not mapped on the first resource. This allows for accurate and efficient reception of urgent messages, improving transmission efficiency. Furthermore, it avoids frequent beam switching and ensures that both the transmitting and receiving devices have a consistent understanding of the PDSCH mapping, preventing unnecessary resource waste and improving reception performance.

[0033] In conjunction with the first aspect, in some possible designs, a second indication information is obtained, which is used to indicate that the beam corresponding to the first PDSCH is different from the beam corresponding to the third PDSCH, with the third PDSCH preceding the first PDSCH.

[0034] In the above scheme, the second indication information can be obtained by higher-layer signaling or physical layer configuration. When the transmitting device receives the second indication information, it knows that the beam corresponding to the first PDSCH is different from the beam corresponding to the PDSCH (third PDSCH) scheduled at the previous moment. It is necessary to further determine whether the first PDSCH and the first beam are the same, which can avoid frequent beam switching. At the same time, it is beneficial for the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve reception performance.

[0035] In a second aspect, a resource device method is provided, the method comprising: receiving signals from a first data channel and a second data channel, wherein the beams corresponding to the first data channel and the second data channel are different, the first data channel is mapped to symbols in a first resource other than at least one second symbol and / or the second data channel is mapped to symbols in a second resource other than at least one second symbol, the first resource and the second resource include M first symbols, the first symbols being symbols not mapped to the first data channel and not mapped to the second data channel, the first symbols and the second symbols being adjacent, M being an integer and N≥0, the sum of the number of second symbols and the number of first symbols being equal to a first threshold; and processing the received signals.

[0036] In the above scheme, the sum of the number of first symbols and the number of second symbols equals a first threshold, and the first and second symbols are adjacent. The second symbols are symbols not mapped to the first data channel and / or the second data channel. If the beams corresponding to the first and second data channels are different, and the number of second symbols is less than the first threshold, it may lead to inconsistencies between the transmitting and receiving devices regarding which symbols the data channels should be mapped, thus reducing reception performance. Therefore, symbols in the first resource (excluding at least one first symbol) can be mapped to the first data channel, and / or symbols in the second resource (excluding at least one first symbol) can be mapped to the second data channel. This ensures consistency in the understanding of resource mapping between the transmitting and receiving devices, avoiding unnecessary resource waste.

[0037] It should be understood that the first data channel and the second data channel in the above scheme are scheduled sequentially in the time domain. That is, from the time domain perspective, the first data channel is sent at a time before the second data channel, or the first data channel is sent at a time after the second data channel. In addition, the first data channel and the second data channel can be in the same time unit or in different time units. This application does not impose any restrictions on this.

[0038] In conjunction with the second aspect, in some possible designs, the method further includes: receiving a reference signal mapped to the Nth symbol after the third symbol, the Nth symbol being determined based on the position of the symbol of the reference signal to be mapped, the third symbol including the first symbol and the second symbol, wherein N is a positive integer greater than or equal to 1; and processing the received reference signal.

[0039] In conjunction with the second aspect, in some possible designs, the symbol of the reference signal to be mapped overlaps with the third symbol; or, there is no symbol of the reference signal to be mapped on the second resource, wherein the second resource follows the first resource; or, the first resource follows the second resource, and there is no symbol of the reference signal to be mapped on the first resource.

[0040] In conjunction with the second aspect, in some possible designs, the method further includes: if the symbol of the first signal to be mapped overlaps with the third symbol, the first signal is not mapped onto the third symbol, and the first signal includes a set of control resources.

[0041] In conjunction with the second aspect, in some possible designs, the method further includes: switching from the beam corresponding to the first data channel to the beam corresponding to the second data channel at the beam switching position, with the beam switching position preceding the third symbol.

[0042] In conjunction with the second aspect, in some possible designs, the first resource is determined according to the first resource indication information, and the second resource is determined according to the second resource indication information. The first resource indication information is used to indicate the symbol for mapping the first data channel, and the second resource indication information is used to indicate the symbol for mapping the second data channel. The value range of the first resource indication information is determined according to the first threshold, and the value range of the second resource indication information is determined according to the first threshold.

[0043] In some possible designs, the first resource indication information may be start and length indication information SLIV, and the second resource indication information may be start and length indication information SLIV, but this application does not limit this.

[0044] In some possible designs, the value range of the first resource indication information is determined according to a first threshold. Specifically, the value range of the starting S is determined according to the first threshold. For example, the starting S is not less than the first threshold. The same applies to the second resource indication information. This application does not impose any further limitations.

[0045] In conjunction with the second aspect, in some possible designs, the first data channel is the first physical downlink shared channel (PDSCH), and the second data channel is the second PDSCH; or, the first data channel is the first physical uplink shared channel (PUSCH), and the second data channel is the second PUSCH.

[0046] It should be understood that the first data channel and the second data channel should be data channels of the same type, that is, both should be PDSCH or both should be PUSCH. When both are PDSCH, the sending device can be a network device. When both are PUSCH, the sending device is a terminal device.

[0047] In conjunction with the second aspect, in some possible designs, when the first data channel is the first physical downlink shared channel (PDSCH), if the beam corresponding to the first PDSCH is the same as the first beam, the first PDSCH is mapped to the first resource.

[0048] In conjunction with the second aspect, in some possible designs, when the first data channel is the first physical downlink shared channel (PDSCH), if the beam corresponding to the first PDSCH is different from the first beam, the first PDSCH is not mapped to the first resource.

[0049] In the above scheme, determining whether to map the first PDSCH on the first resource based on whether the beam corresponding to the first PDSCH is the same as the first beam can avoid frequent beam switching. At the same time, it is beneficial for the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve receiving performance.

[0050] In conjunction with the second aspect, in some possible designs, the first beam is the second beam or the third beam, the second beam is the beam corresponding to the first indication information or a pre-configured beam, and the third beam is the beam corresponding to the first indication information, the beam indicated by the first indication information, or a pre-configured beam.

[0051] In conjunction with the second aspect, in some possible designs, before the end of the first duration, if the beam corresponding to the first PDSCH is the same as the first beam, the first PDSCH is mapped to the first resource, including: if the beam corresponding to the first PDSCH is the same as the second beam, the first PDSCH is mapped to the first resource; or, if the beam corresponding to the first PDSCH is different from the second beam, the first PDSCH is not mapped to the first resource; wherein, the first duration is related to the processing time of the terminal device.

[0052] It should be understood that the first duration is related to the processing time of the terminal device, which can be understood as the terminal device determining the first duration. Specifically, the first duration is the sum of the time the terminal device processes the first indication information and the time used for beam switching, or the first duration is the time from when the terminal device receives the first indication information to when the beam switching ends.

[0053] In conjunction with the second aspect, in some possible designs, after the end of the first duration, if the beam corresponding to the first PDSCH is the same as the first beam, the mapping of the first PDSCH to the first resource includes: if the first PDSCH has a high priority and the beam corresponding to the first PDSCH is the same as the third beam, the first PDSCH is mapped to the first resource; or, if the first PDSCH has a high priority and the beam corresponding to the first PDSCH is different from the third beam, the first PDSCH is not mapped to the first resource; wherein, the first duration is related to the processing time of the terminal device.

[0054] In conjunction with the second aspect, in some possible designs, a second indication information is obtained, which is used to indicate that the beam corresponding to the first PDSCH is different from the beam corresponding to the third PDSCH, wherein the third PDSCH is before the first PDSCH.

[0055] The beneficial effects of the resource mapping method described above can be found in the detailed description in the first aspect, and will not be repeated here for the sake of brevity.

[0056] Thirdly, a resource mapping method is provided, which can be executed by a network device or by a chip configured in the network device. The method includes: mapping the first PDSCH onto the first resource if the beam corresponding to the first physical downlink shared channel (PDSCH) is the same as the first beam; transmitting a signal on the first PDSCH; or, if the beam corresponding to the first PDSCH is not the same as the first beam, not mapping the first PDSCH onto the first resource.

[0057] In the above scheme, determining whether to map the first PDSCH on the first resource based on whether the beam corresponding to the first PDSCH is the same as the first beam can avoid frequent beam switching. At the same time, it is beneficial for the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve receiving performance.

[0058] In conjunction with the third aspect, in some possible designs, the first beam is the second beam or the third beam, the second beam is the beam corresponding to the first indication information or a pre-configured beam, and the third beam is the beam corresponding to the first indication information, the beam indicated by the first indication information, or a pre-configured beam.

[0059] In conjunction with the third aspect, in some possible designs, before the end of the first duration, if the beam corresponding to the first physical downlink shared channel (PDSCH) is the same as the first beam, mapping the first PDSCH on the first resource includes: if the beam corresponding to the first PDSCH is the same as the second beam, mapping the first PDSCH on the first resource; or, if the beam corresponding to the first PDSCH is different from the second beam, not mapping the first PDSCH on the first resource; wherein, the first duration is related to the processing time of the terminal device.

[0060] It should be understood that the first duration is related to the processing time of the terminal device, which can be understood as the terminal device determining the first duration. Specifically, the first duration is the sum of the time the terminal device processes the first indication information and the time used for beam switching, or the first duration is the time from when the terminal device receives the first indication information to when the beam switching ends.

[0061] In the above scheme, for the symbols to be mapped before the end of the first duration, the beam corresponding to the first PDSCH is compared with the second beam. If they are the same, the first PDSCH is mapped on the first resource; otherwise, the first PDSCH is not mapped on the first resource. This can avoid frequent beam switching and also help the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve receiving performance.

[0063] In the above scheme, for symbols to be mapped after the end of the first duration, the beam corresponding to the high-priority first PDSCH is compared with the second beam. If they are the same, the first PDSCH is mapped on the first resource; otherwise, it is not mapped on the first resource. This allows for accurate and efficient reception of urgent service messages, improving transmission efficiency. Furthermore, it avoids frequent beam switching and ensures that both the transmitting and receiving devices have a consistent understanding of the PDSCH mapping, preventing unnecessary resource waste and improving reception performance.

[0065] In the above scheme, the second indication information can be obtained by higher-layer signaling or physical layer configuration. When the transmitting device receives the second indication information, it knows that the beam corresponding to the first PDSCH is different from the beam corresponding to the PDSCH (third PDSCH) scheduled at the previous moment. It is necessary to further determine whether the first PDSCH and the first beam are the same, which can avoid frequent beam switching. At the same time, it is beneficial for the transmitting and receiving devices to have a consistent understanding of the PDSCH mapping, avoid unnecessary resource waste, and improve reception performance.

[0073] The beneficial effects of the resource mapping method described above can be found in the detailed description in the third aspect, which will not be elaborated further for the sake of brevity.

[0074] Fifthly, a resource mapping apparatus is provided, comprising: a processing module for mapping symbols in a first resource, excluding at least one first symbol, to a first data channel, and / or the processing module is further configured to map symbols in a second resource, excluding at least one first symbol, to a second data channel; the beams corresponding to the first data channel and the beams corresponding to the second data channel are different; the first resource and the second resource include M second symbols, the second symbols being symbols not mapped to the first data channel and not mapped to the second data channel, the first symbols and the second symbols being adjacent, M being an integer and M≥0, and the sum of the number of first symbols and the number of second symbols being equal to a first threshold; and a transceiver module for transmitting signals on the first data channel and the second data channel.

[0075] In conjunction with the fifth aspect, in some possible designs, the processing module is also used to map the reference signal on the Nth symbol after the third symbol. The Nth symbol is determined according to the position of the symbol of the reference signal to be mapped. The third symbol includes the first symbol and the second symbol, and N is a positive integer greater than or equal to 1. The transceiver module is also used to transmit the reference signal.

[0140] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0141] Figure 1 This is a schematic diagram of a wireless communication system 100 applicable to embodiments of this application. For example... Figure 1 As shown, the wireless communication system 100 may include at least one network device 101, and the network device 101 is connected to at least one terminal device (e.g., Figure 1 The terminal device 102 shown performs wireless communication. The network device 101 schedules multiple time units of PDSCH or PUSCH for the terminal device. Figure 1 The PDSCH shown occupies multiple time units (e.g., Figure 1 As shown in time units 1 and 2, PUSCH also occupies multiple time units (e.g., such as time units 1 and 2). Figure 1 (Time unit 3 and time unit 4 shown).

[0142] It should be understood that Figure 1 This is merely an illustrative example. A PDSCH can occupy multiple time units, or a PDSCH can occupy one time unit with different PDSCHs in each time unit, or there may be cases where any two or more time units have different PDSCHs. The same applies to PUSCH, which will not be described in detail in the embodiments of this application.

[0143] The technical solutions of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) system, 5th Generation (5G) system, or NR, etc.

The terminal device can also be a cellular phone, smartphone, wireless data card, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), tablet computer, laptop computer, handset with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a 5G network, terminal device in a public land mobile network (PLMN) and machine type communication (MTC), or vehicle-mounted communication device, vehicle-mounted communication chip, roadside unit or communication device in a roadside unit, or equipment used in industrial scenarios, etc., which are not limited in this application embodiment.

[0145] Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction. Broadly defined, wearable smart devices include those with comprehensive functions, large sizes, and the ability to perform complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses. They also include devices focused on a specific application function that require the use of other devices, such as smart bracelets and smart jewelry for vital sign monitoring.

[0146] The network device in this application embodiment can be a device for communicating with terminal devices, and can be any device with transceiver functions. The network device can be an evolved NodeB (eNB or eNodeB) in an LTE system, or a radio controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay station, access point, vehicle-mounted device, wearable device, or a network device in a future 5G network or a network device in a future evolved PLMN network, etc., and this application embodiment is not limited.

[0147] Furthermore, in the embodiments of this application, the network device can be a device in the RAN, or in other words, a RAN node that connects the terminal device to the wireless network. For example, by way of example and not limitation, the following can be listed as base stations: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B, HNB), base band unit (BBU), etc. In a network architecture, the network device can include a centralized unit (CU) node, or a distributed unit (DU) node, or a RAN device including CU nodes and DU nodes, or a RAN device comprising control plane CU nodes (CU-CP nodes), user plane CU nodes (CU-UP nodes), and DU nodes.

[0148] Network equipment provides services to a cell. Terminal devices communicate with the base station through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the base station (e.g., a base station). The cell can belong to a macro base station or to the base station corresponding to a small cell. The small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0149] To facilitate understanding of the embodiments of this application, the concepts involved in the embodiments of this application will be explained first below.

[0150] In NR, beams are introduced into the communication system. A beam is a communication resource; it can also be called a spatial domain filter (SDF) or a transmission state indicator (TCI), etc.

[0151] Beams can be divided into transmit beams and receive beams. Beamforming techniques can be beamforming or other methods. Beamforming includes transmit beamforming and receive beamforming.

[0152] Optionally, multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and probe signals, etc.

[0153] Transmit beam: This refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna. The transmitting end sends signals with certain beamforming weights, creating a spatially directional beam. In the uplink direction, the transmitting end can be a terminal device; in the downlink direction, the transmitting end can be a network device.

[0154] Received beam: This refers to the distribution of an antenna array to strengthen or weaken the reception of wireless signals in different spatial directions. The receiving end receives the signal with certain beamforming weights, resulting in a spatially directional beam. In the uplink direction, the receiving end can be a network device; in the downlink direction, the receiving end can be a terminal device.

[0155] Transmit beamforming: When a transmitting device with an antenna array transmits a signal, a specific amplitude and phase are set on each antenna element of the antenna array to give the transmitted signal a certain spatial directivity. That is, the signal power is high in some directions and low in some directions, and the direction with the highest signal power is the direction of the transmitted beam. The antenna array consists of multiple antenna elements, and the specific amplitude and phase added are the beamforming weights.

[0156] Receiver beamforming: When a receiver with an antenna array receives a signal, a specific amplitude and phase are set on each antenna element of the array to make the power gain of the received signal directional. That is, the power gain is high when receiving signals in certain directions, and low when receiving signals in other directions. The direction with the highest power gain is the direction of the received beam. The antenna array consists of multiple antenna elements, and the specific amplitude and phase added are the beamforming weights.

[0157] Sending a signal using a specific transmit beam: Sending a signal using a specific beamforming weight.

[0158] Receive signal using receive beam: Receive signal using a specific beamforming weight.

[0159] Different beams can be considered as different resources; using (or through) different beams can transmit the same information or different information.

[0160] Quasi-colocation (QCL): If the channel characteristics of a symbol transmitted on one antenna port can be inferred from the channel characteristics of a symbol transmitted on another antenna port, then the two antenna ports are said to have a QCL relationship. In the NR protocol, QCL relationships can be classified into the following four types based on different parameters:

[0161] Type A: Doppler frequency shift, Doppler spread, average time delay, time delay spread;

[0162] Type B: Doppler frequency shift, Doppler spread;

[0163] Type C: Doppler shift, average time delay; and

[0164] Type D: Space reception parameters.

[0165] In this application, the terminal device can determine the required beam direction through the QCL relationship. The QCL involved in the embodiments of this application is a type D QCL, i.e., a reception relationship. Unless otherwise specified, QCL can be understood as a type D QCL, i.e., a QCL defined based on spatial reception parameters. Specifically, two signals in the same beam have a QCL relationship with respect to spatial Rx parameters. That is, the existing protocol's QCL - Type D: {Spatial Rxparameter}.

[0166] Type D QCL can also be understood from both the transmitting and receiving perspectives. From the transmitting perspective, if two antenna ports have spatial QCL, it means that the corresponding beam directions of these two antenna ports are spatially aligned. From the receiving perspective, if two antenna ports have spatial QCL, it means that the receiving end can receive the signals transmitted by these two antenna ports in the same beam direction.

[0167] Signals transmitted on ports with spatial QCL relationships can also have corresponding beams, and the corresponding beams include at least one of the following: the same receiving beam, the same transmitting beam, the transmitting beam corresponding to the receiving beam, and the receiving beam corresponding to the transmitting beam.

[0168] Signals transmitted on ports with spatial QCL relationships can also be understood as signals received or transmitted using the same spatial filter. The spatial filter can be at least one of the following: precoding, antenna port weighting, antenna port phase deflection, or antenna port amplitude gain.

[0169] Signals transmitted on ports with spatial QCL relationships can also be understood as having corresponding beam pair links (BPLs). A corresponding BPL includes at least one of the following: the same downlink BPL, the same uplink BPL, an uplink BPL corresponding to the downlink BPL, and a downlink BPL corresponding to the uplink BPL.

[0170] Therefore, spatial reception parameters (i.e., QCL of type D) can be understood as parameters used to indicate the direction information of the received beam.

[0171] Transmission Configuration Indicator (TCI): In this application, TCI can be used to indicate and determine the beam direction used by the terminal device (including the direction of the receiving beam and the direction of the transmitting beam). For example, if the TCI corresponding to the PDCCH in time slot 1 is 1, it can represent that the receiving beam direction of the terminal device has a QCL type D relationship with reference signal 1; if the DCI carried by the PDCCH in time slot 1 indicates that the TCI of the PDSCH in time slot 3 it schedules is 3, it can represent that the receiving beam direction of the terminal device for that PDSCH has a QCL type D relationship with reference signal 2. TCI can be indicated by radio resource control (RRC) signaling, medium access control (MAC) signaling, or DCI signaling. In terms of effective time, RRC > MAC > DCI. For example, the effective time of RRC signaling is in the tens of milliseconds, the effective time of MAC signaling is in the milliseconds, and the effective time of DCI signaling is less than 1 millisecond.

[0172] The beams involved in the embodiments of this application can also be referred to as beam configurations or beam directions. Beam direction can be understood as spatial domain filtering, TCI, or QCL. Different beam directions can be understood as employing different spatial domain filters, different QCL assumptions, or different TCI configurations. This application does not impose further restrictions on this.

[0173] QCL Duration (timeDurationForQCL): The minimum number of OFDM symbols required for the terminal device to receive the PDCCH and apply the spatial QCL information received from the DCI to the PDSCH processing. The terminal device will indicate a value representing the minimum number of OFDM symbols per subcarrier interval.

[0174] When DCI schedules PDSCH, assuming the DCI also indicates the TCI state corresponding to the PDSCH, the terminal device needs to wait for a period of time equal to the QCL duration after detecting the DCI before it can switch its beam from other beam directions to the beam direction corresponding to the TCI indicated by the DCI. This is because during this period, the terminal device has not yet completed decoding the DCI and does not know where the PDSCH scheduled by the DCI started. Therefore, during this period, the terminal device needs to receive and buffer various signals according to the default beam direction. After the terminal device completes decoding the DCI, if it finds that the beam direction corresponding to the TCI indicated by the DCI is different from the current beam direction, it still needs time to complete the beam switching. Therefore, the QCL duration reflects the DCI processing time and the beam switching time. Only after these processes are completed can the terminal device receive the PDSCH according to the beam direction corresponding to the TCI indicated by the DCI.

[0175] To accommodate different business needs, NR can support both time-slot-based and non-time-slot-based scheduling. NR's DCI has dedicated time-domain resource allocation information bits that indicate different time-domain configuration information for PDSCH and PUSCH. This information includes time-domain offset value, time-domain start symbol S, and time-domain symbol number L.

[0176] For example, the time-domain offset values ​​can be K0 and K2, where K0 refers to the time unit interval between the downlink scheduling DCI and its scheduled PDSCH, and K2 refers to the time unit interval between the uplink scheduling DCI and its scheduled PUSCH.

[0177] Subcarrier spacing (SCS): Generally, the larger the SCS, the shorter the corresponding time unit. Taking a time unit as an example, if the SCS is 15kHz, one time slot is 1 millisecond long, and there are 14 symbols within 1 millisecond. If the SCS is 60kHz, there will be 14*4 symbols, or 56 symbols, within 1 millisecond, and the time slot length will be 1 / 4 millisecond, or 0.25 milliseconds.

[0178] When the SCS is relatively small, the time corresponding to each symbol is also relatively long. When terminal devices and network devices want to switch beam directions, the switching time is shorter than the time corresponding to the symbol. Therefore, if a switch occurs, it will not cause the symbol to be occupied. In addition, the length of QCL will not exceed 2 time slots, or even less than 1 time slot.

[0179] In cases with large SCS (Signal Size Range), such as SCS greater than or equal to 480kHz, the corresponding time for a symbol is relatively short. In some cases, the corresponding time for a symbol may be shorter than the beam switching duration, resulting in the entire symbol being occupied. During beam switching, occupied symbols cannot be used for PDSCH or PUSCH transmission. When PDSCH or PUSCH is continuously scheduled across multiple time units, there may be inconsistencies in the understanding of PDSCH or PUSCH resource mapping between terminal devices and network devices. That is, the terminal device may believe that PDSCH or PUSCH is transmitted continuously across multiple time units, but during beam switching, some PDSCH or PUSCH cannot be transmitted due to symbol occupancy, thus resulting in discontinuous PDSCH or PUSCH resource mapping.

[0180] Therefore, this application proposes a resource mapping method to improve the receiving performance of terminal devices and network devices.

[0181] Figure 2 This is a flowchart illustrating a resource mapping method proposed in this application, as shown below. Figure 2 As shown, the method may include steps S210 to S230. Each step is described in detail below.

[0182] S210, the transmitting device maps symbols other than at least one first symbol in the first resource to the first data channel and / or maps symbols other than at least one first symbol in the second resource to the second data channel.

[0183] S220, the transmitting device transmits signals on the first data channel and the second data channel.

[0184] S230, the receiving device processes the received signal.

[0185] Specifically, symbols in the first resource, excluding at least one second symbol, are mapped to the first data channel, and / or symbols in the second resource, excluding at least one first symbol, are mapped to the second data channel. The beam corresponding to the first data channel is different from the beam corresponding to the second data channel. The first and second resources include M second symbols, which are symbols not mapped to the first and / or second data channels. The first and second symbols are adjacent, M is an integer, and M≥0. The sum of the number of first symbols and the number of second symbols equals a first threshold. For example, the second symbol can be a symbol mapped to a source other than the first and second data channels, such as a control resource set (CORESET).

[0186] The first data channel and the second data channel can be data channels of the same type. For example, if the first data channel is PDSCH, the second data channel is also PDSCH; or if the first data channel is PUSCH, the second data channel is also PUSCH.

[0187] For example, when the data channel is PDSCH, the transmitting device can be a network device and the receiving device can be a terminal device; when the data channel is PUSCH, the transmitting device can be a terminal device and the receiving device can be a network device.

[0188] The embodiments of this application can be applied to multi-time-unit scheduling data channels.

[0189] For example, a time unit can be a symbol, a mini-slot, a slot, or a subframe. The method proposed in this application is not limited to this, but in the embodiments of this application, a time unit will be used as a slot for description. For the implementation process of other time units, please refer to the embodiments of this application.

[0190] The transmitting device can map a data channel on time-frequency resources to send data to the receiving device. This application embodiment uses mapping a data channel in the time domain as an example for illustration.

[0191] When a transmitting device sends a signal in a data channel, it first determines which spatial domain to transmit in. In other words, the transmitting device determines the beam direction corresponding to its data channel signal transmission. This beam direction can also be understood as spatial filtering, QCL assumption, or TCI state, etc.

[0192] In this application, the beam corresponding to the first data channel and the beam corresponding to the second data channel are different. The beam corresponding to the first data channel refers to the beam used to map the first data channel or to transmit the first data channel, and the beam corresponding to the second data channel also refers to the beam used to map the first data channel or to transmit the first data channel.

[0193] For example, the first data channel corresponds to beam #1, and the second data channel corresponds to beam #2. If beam #1 and beam #2 are different, then the beams corresponding to the first and second data channels are considered different. If beam #1 and beam #2 are the same, then the beams corresponding to the first and second data channels are considered the same. Different beam directions can be understood as using different spatial filters, different beamwidths, or different beam configurations.

[0194] Specifically, determining whether the beam corresponding to the first data channel and the beam corresponding to the second data channel are the same can be done by checking whether the default beams corresponding to the data channels are the same, or by checking whether the beam used when sending the indication information is the same as the beam indicated by the indication information. The indication information is used to instruct the scheduling of the first data channel and the second data channel, and this indication information includes, but is not limited to, DCI.

[0195] For example, the first data channel and the second data channel in this application are scheduled based on the time domain. That is, from the time domain perspective, the first data channel is sent at a time before the second data channel, or the first data channel is sent at a time after the second data channel. In addition, the first data channel and the second data channel can be in the same time unit or in different time units.

[0196] If the beams corresponding to the first data channel and the second data channel are different, beam switching may occur. Therefore, it is necessary to determine the number of second symbols, i.e., M second symbols are included between the first resource and the second resource. The second symbols are symbols that are not mapped to the first data channel and / or the second data channel, or the second symbols are symbols used for beam switching, where M is an integer and M≥0.

[0197] For example, the first resource is determined by the first resource indication information corresponding to the first data channel, and the second resource is determined by the second resource indication information corresponding to the second data channel. The first resource can occupy multiple symbols.

[0198] Optionally, the resource indication information may be start and length indication value (SLIV), or an indication of the start symbol S and the allocated length L, or the resource indication information may directly indicate which symbols need to be mapped to the data channel.

[0199] In different implementations, the first resource and the second resource may be located in the same time unit or in different time units.

[0200] For example, the same time unit mentioned above can be understood as the same time slot, for example, the first resource is located in symbols 0 to 5 of time slot #1, and the second resource is located in symbols 8 to 12 of time slot #1.

[0201] The first resource and the second resource include M second symbols. This can also be understood as the second symbols being located between the first resource and the second resource, or the second symbols being located between the last symbol of the first resource and the start symbol of the second resource to be mapped, or the second symbols being located after the first resource and before the second resource.

[0202] The following explanation will use the first resource as the first symbol to be mapped and the second resource as the second symbol to be mapped as an example.

[0203] For example, such as Figure 3 As shown, the total number of symbols scheduled by the transmitting device for the receiving device in one operation is 9. Among them, the first symbol to be mapped occupies 3, the second symbol to be mapped occupies 4, and there are 2 second symbols between the first and second symbols to be mapped. These second symbols are neither mapped to the first data channel nor mapped to the second data channel.

[0204] When the first symbol to be mapped and the second symbol to be mapped are located in two different time units, the number of the first symbol is determined according to the two resource indication information. The second symbol can be located in one time unit or in the two time units mentioned above.

[0205] For example, such as Figure 4 As shown, the first symbol to be mapped is located in the first time unit, and the second symbol to be mapped is located in the second time unit. The first time unit precedes the second time unit. Each of the first and second time units has 9 symbols, with 2 symbols for the second symbol. The second symbol can be located in the first time unit, meaning the starting symbol of the second symbol to be mapped is the first symbol of the second time unit, as shown below. Figure 4 In (a); the second symbol can be located in the second time unit, that is, the last symbol of the first symbol to be mapped is the last symbol of the first time unit, such as Figure 4 In (b); when the second symbol can be located in either the first or second time unit, the last symbol of the first symbol to be mapped is located before the last symbol of the first time unit, and the first symbol of the second symbol to be mapped is located after the first symbol of the second time unit, as shown in example. Figure 4 In (c), one second symbol is located in the first time unit, and one second symbol is located in the second time unit. Figure 4 (a) to (c) are examples. In other implementations, the second symbol may have other distribution methods.

[0206] After determining the number of second symbols, the transmitting device compares the number of second symbols with a first threshold. If the number of second symbols is less than the first threshold, the transmitting device maps the symbols in the first set of symbols to be mapped, excluding at least one first symbol, to the first data channel and / or maps the symbols in the second set of symbols to be mapped, excluding at least one first symbol, to the second data channel.

[0207] The sum of the first symbol and the second symbol equals the first threshold. In other words, the number of the first symbol depends on the number of the second symbol and the first threshold, which can be expressed by the formula: the number of the first symbol T1 = the first threshold - the number of the second symbol T2. Any expression that satisfies the condition that the number of the first symbol is determined based on the number of the second symbol and the first threshold falls within the scope of protection of the embodiments of this application.

[0208] Optionally, the first threshold can be understood as the time required for beam switching, and the number of symbols corresponding to this time is the threshold. This first threshold can be determined by the capabilities of the terminal device, or it can be directly defined by the protocol. For example, when the SCS is relatively large, the time corresponding to each symbol is relatively short. For example, when the SCS is 960kHz, the protocol can stipulate that the terminal device does not need to report capability information. Alternatively, the terminal device can directly inform the network device of the length of time required for beam switching, or the number of symbols that will be affected.

[0209] For example, beam switching requires four symbols, and the number of second symbols is two. Therefore, it is necessary to select two first symbols connected to the second symbols from the first symbols to be mapped that are not mapped to the first data channel, such as... Figure 5 (a) in the second symbol to be mapped; or select two first symbols connected to the second symbol not to map the second data channel, such as Figure 5 (b) in the first symbol to be mapped; or selecting one first symbol connected to the second symbol in the first symbol to be mapped and not mapping the first data channel, and selecting one first symbol connected to the second symbol in the second symbol to be mapped and not mapping the second data channel, such as Figure 5 (c) Wherein, the symbol that should have been mapped to the data channel but was not is called the first symbol. The above can also be described as follows: in the first set of symbols to be mapped, symbols other than at least one first symbol are mapped to the first data channel, and / or in the second set of symbols to be mapped, symbols other than at least one first symbol are mapped to the second data channel.

[0210] It should be noted that the number of the second symbol can also be 0, which means there are no unmapped symbols between the first and second symbols to be mapped, or the last symbol of the first symbol to be mapped is adjacent to the start symbol of the second symbol to be mapped. In this case, the number of the first symbol is equal to the first threshold, that is, the number of the first symbol is equal to the number of symbols required when switching beams.

[0211] In one possible implementation, the transmitting device maps a reference signal on the Nth symbol after the third symbol. The value of N is determined based on the position of the symbol of the reference signal to be mapped. The third symbol includes the first and second symbols, and N is a positive integer greater than or equal to 1. The third symbol can be called the "switching symbol," that is, the symbol affected when switching beams. Alternatively, it can be understood that the transmitting device can determine, based on the position of the reference signal to be mapped, to map the reference signal on the Nth symbol after the third symbol, where N is a positive integer greater than or equal to 1.

[0212] Specifically, if the position of the reference signal to be mapped overlaps with the third symbol, or if the number of second symbols is less than the first threshold, the data channel is not mapped on the symbol originally used for mapping the data channel. Similarly, if the symbol originally used for mapping the data channel is also used for mapping the reference signal, the reference signal is not mapped on that symbol either. Therefore, the position of the actual mapped reference signal needs to be changed; it can be on the Nth symbol after the third symbol.

[0213] In another possible implementation, if the symbol to be mapped after beam switching does not contain a symbol for the reference signal to be mapped, a reference signal also needs to be added to the Nth symbol after the third symbol.

[0214] For example, if there is no symbol of the reference signal to be mapped on the second symbol to be mapped, and the second symbol to be mapped is after the first symbol to be mapped, then the reference signal needs to be mapped on the Nth symbol after the third symbol.

[0215] Optionally, the reference signal (RS) can be a demodulation reference signal (DMRS).

[0216] In one possible implementation, if the symbol of the first signal to be mapped overlaps with the third symbol, the first signal is not mapped onto the third symbol. This can also be understood as the transmitting device determining the position of the symbol of the first signal to be mapped, and when the symbol of the first signal to be mapped overlaps with the third symbol, the first signal is not mapped onto the third symbol.

[0217] Optionally, the first signal can be a control resource set (CORESET).

[0218] For example, if there are symbols in the first symbol that are used to map CORESET, then CORESET will not be mapped on those symbols in the first symbol that were originally used to map CORESET.

[0219] In one possible implementation, the beam switching position is located at the beam switching point, where the beam switches from the beam corresponding to the first data channel to the beam corresponding to the second data channel, and the beam switching position is before the third symbol.

[0220] Specifically, the first data channel and the second data channel are two data channels that are adjacent in the time domain. In other words, the first data channel and the second data channel are transmitted sequentially in the time domain, and they each correspond to different beams. To ensure that the transmitting and receiving devices have a consistent understanding of the beam switching, both need to know the starting point of the beam switching. The transmitting device can inform the receiving device of the beam switching location, and it can also inform the receiving device of the switching mode, such as which data channels use beam 1 and which data channels use beam 2, etc.

[0221] In one possible implementation, the value range of the first resource indication information is determined according to a first threshold, and the value range of the second resource indication information is also determined according to the first threshold.

[0222] Specifically, the range of values ​​for the initial symbol is determined based on a first threshold. For example, S is not less than the first threshold, meaning S is greater than or equal to the number of symbols required for beam switching.

[0223] In the above description, the rules for mapping the data channel by the sending device are also communicated to the receiving device. In other words, the protocol predefines the same mapping rules for both the sending and receiving devices. After the sending device maps the data channel according to these rules, the receiving device receives and decodes the data channel according to the same rules. The specific implementation details are not described in detail in this application's embodiments.

[0224] The following will use the mapping of PDSCH for network devices and PUSCH for terminal devices as examples to illustrate the process.

[0225] For example, the above description will be explained in detail using the scheduling of PDSCH as an example. The following description uses time units as time slots as an example.

[0226] When a network device needs to send data to a terminal device, it needs to map the PDSCH on the time-frequency resource. This application mainly uses the mapping of PDSCH in the time domain as an example for illustration.

[0227] The network device first determines the airspace to transmit over, or in other words, it determines the beam for transmitting the PDSCH. This beam can also be understood as spatial filtering, QCL assumption, or TCI state, etc. This application uses two time slots as an example for illustration, namely time slot #1 and time slot #2. Both time slot #1 and time slot #2 consist of 14 symbols. PDSCH #1 is mapped to time slot #1, and PDSCH #2 is mapped to time slot #2.

[0228] In one possible implementation, the network device determines that two adjacent PDSCHs in the time domain correspond to different beams, and the number of symbols that do not carry data between the two PDSCHs is smaller than the number of symbols affected by beam switching.

[0229] For example, a network device can determine that the beam corresponding to the PDSCH is different in the following ways:

[0230] Method 1:

[0231] The network device sends a Data Interchange Message (DCI) to the terminal device. This DCI is used to schedule the PDSCH. In addition, the DCI can also indicate the beam, that is, instruct the terminal device to receive data according to the indicated beam of the corresponding PDSCH. When the beam used to send the DCI is different from the beam indicated by the DCI for receiving the PDSCH, the network device can determine that a beam switch will occur between two PDSCHs, or in other words, a beam switch will occur between a PDSCH corresponding to the end of the QCL (time duration for QCL) and the next PDSCH of that PDSCH.

[0232] In this application, if PDSCH#1 and PDSCH#2 are adjacent and switching occurs between them, it can be considered that the beam corresponding to PDSCH#1 and the beam corresponding to PDSCH#2 are different. If only PDSCH#1 is mapped on time slot #1 and only PDSCH#2 is mapped on time slot #2, the beam corresponding to PDSCH#1 and the beam corresponding to PDSCH#2 are different, which can also be understood as the beam corresponding to time slot #1 and the beam corresponding to time slot #2 being different.

[0233] Method 2:

[0234] For a PDSCH prior to the QCL duration, if two adjacent PDSCHs in the time domain correspond to different default beams, the network device can also determine that the two PDSCHs correspond to different beams.

[0235] Method 3:

[0236] Network devices can also determine that two adjacent PDSCHs in the time domain correspond to different beams by observing the beam switching location. This beam switching location can be obtained through higher-layer signaling or physical layer configuration. When a network device knows the beam switching location, it can determine which two PDSCHs will switch beams, meaning that the two adjacent PDSCHs correspond to different beams.

[0237] The above is merely an exemplary description of determining that two adjacent PDSCHs in the time domain correspond to different beams. Any method that enables a network device to determine that two PDSCHs correspond to different beams falls within the protection scope of this application. Therefore, this application will not list and describe them one by one.

[0238] The symbol that does not carry data between two PDSCHs (the second symbol) can be determined through resource indication information. Each PDSCH has its corresponding resource indication information, which indicates the symbol that needs to be mapped to the PDSCH. Specifically, this can be an SLIV, or an indication of the start symbol S and the allocation length L, or the resource indication information can directly indicate which symbol needs to be mapped to the PDSCH. In this way, the resources used to carry the previous PDSCH and the resources used to carry the next PDSCH can be determined. The symbol that does not carry data between two PDSCHs can be understood as the symbol that does not carry data between the last symbol indicated by the resource indication information of the previous PDSCH and the start symbol indicated by the resource indication information of the next PDSCH.

[0239] For example, taking resource indication information as SLIV, and two PDSCHs, PDSCH#1 and PDSCH#2, as an example within the same time unit (using time slots as an example), each time slot has a total of 14 symbols, namely symbols 0 to 13. PDSCH#1 corresponds to S=0, L=3, which can be understood as three consecutive symbols starting from symbol 0. PDSCH#2 corresponds to S=5, L=4, which can be understood as four consecutive symbols starting from symbol 5. There are no other PDSCHs between PDSCH#1 and PDSCH#2; therefore, there are two symbols between these two PDSCHs that do not carry data: symbols 3 and 4.

[0240] For example, taking the resource indication information as SLIV, with a total of 14 symbols (symbols 0 to 13) in each time slot as an example, PDSCH#1 is mapped to time slot #1, and PDSCH#2 is mapped to time slot #2. Time slots #1 and #2 are adjacent time slots, and time slot #1 maps only PDSCH#1, while time slot #2 maps only PDSCH#2. PDSCH#1 corresponds to S=0, L=7, that is, 7 consecutive symbols starting from symbol 0; PDSCH#2 corresponds to S=3, L=5, that is, 5 consecutive symbols starting from symbol 3, with time slot #1 preceding time slot #2. The symbols that do not carry data between these two PDSCHs are: symbols 7 to 13 in time slot #1, and symbols 0 to 2 in time slot #2. Therefore, in this application, there are a total of 10 symbols that do not carry data between the two PDSCHs.

[0241] For example, let's continue with the resource indication information (SLIV) and the example of 14 symbols per time slot. PDSCH#1 is mapped to time slot #1, and PDSCH#2 is mapped to time slot #2. Time slots #1 and #2 are adjacent. PDSCH#1 corresponds to S=0 and L=14, meaning it corresponds to 14 consecutive symbols starting from symbol 0. PDSCH#2 also corresponds to S=0 and L=14, meaning it corresponds to 14 consecutive symbols starting from symbol 0, with time slot #1 preceding time slot #2. There are 0 symbols between these two PDSCHs that do not carry data.

[0242] In other words, the number of symbols (second symbols) that do not carry data between two adjacent PDSCHs in the time domain can be 0 or a positive integer greater than 0.

[0243] The number of symbols in the above time units and the resource indication information corresponding to each PDSCH are merely illustrative examples. Their specific values ​​are determined based on the actual transmission situation and will not be elaborated upon here.

[0244] The number of symbols required for beam switching is determined based on the capabilities of the terminal device. In other words, the terminal device reports the time required to switch from one beam to another to the network device, and the corresponding number of symbols can be inferred from this time. The specific implementation method is not limited in this application embodiment. Furthermore, in this application embodiment, the time required for beam switching by the terminal device each time it performs a beam switch can be consistent or inconsistent. Therefore, the terminal device can report to the network device only once or multiple times; this application embodiment does not impose any limitations on this.

[0245] When two adjacent PDSCHs in the time domain correspond to different beams, and the number of symbols that do not carry data between the two PDSCHs is less than the number of symbols required for beam switching, the network device can introduce a first symbol. This first symbol can be located in the previous PDSCH, or the second symbol can be located in the current PDSCH, or it can be partially located in the previous PDSCH and partially located in the current PDSCH.

[0246] The first symbol is a symbol among the symbols to be mapped, that is, a symbol originally used for mapping PDSCH. However, if the first symbol is used for beam switching, it will not be mapped to a PDSCH. For example, if the first symbol is located in the previous PDSCH, it can be understood that some PDSCH symbols that originally needed to be mapped in the previous PDSCH are not mapped to that PDSCH. Specifically, if the previous PDSCH originally needed to be mapped to symbols 0 to 13 (symbols to be mapped), but was not mapped to symbols 12 and 13, then symbols 12 and 13 can be called the first symbol.

[0247] For example, the first symbol needs to be before and / or after the second symbol, or the first symbol and the second symbol are adjacent to each other. The first symbol and the second symbol can be referred to as the third symbol, which is the symbol required when switching beams.

[0248] For example, PDSCH#1 was originally mapped to symbols 0 to 11 (the first symbol to be mapped), and PDSCH#2 was originally mapped to symbols 0 to 10 (the second symbol to be mapped). PDSCH#1 is located in time slot #1, and PDSCH#2 is located in time slot #2. Time slot #1 precedes time slot #2. The beams corresponding to PDSCH#1 and PDSCH#2 are different, so beam switching is required. The number of symbols required for beam switching (hereinafter referred to as the first threshold) is 5. However, the number of symbols that do not carry data between the two PDSCHs is 2, which is less than the first threshold. Therefore, it can be confirmed that the first symbol is 3, and its selection can be done in the following ways:

[0249] Method 1: The first symbol is located entirely in PDSCH#1, that is, symbols 9, 10 and 11 in time slot #1 corresponding to PDSCH#1 are no longer mapped to PDSCH#1, and the third symbol is symbols 9 to 13 in time slot #1.

[0250] Method 2: The first symbol is located entirely in PDSCH#2, that is, symbols 0, 1 and 2 in time slot 2 corresponding to PDSCH#2 are no longer mapped to PDSCH#2. The third symbol is symbols 12 and 13 in time slot #1, and symbols 0 to 2 in time slot #2.

[0251] Method 3: Some first symbols are located in PDSCH#1, and some first symbols are located in PDSCH#2. For example, one second symbol is located in PDSCH#1, meaning symbol 11 in slot #1 corresponding to PDSCH#1 is no longer mapped to PDSCH#1; two second symbols are located in PDSCH#2, meaning symbols 0 and 1 in slot 2 corresponding to PDSCH#2 are no longer mapped to PDSCH#2; the third symbol is symbols 11 to 13 in slot #1, and symbols 0 and 1 in slot #2. Another example: two first symbols are located in PDSCH#1, meaning symbols 10 and 11 in slot #1 corresponding to PDSCH#1 are no longer mapped to PDSCH#1; one first symbol is located in PDSCH#2, meaning symbol 0 in slot 2 corresponding to PDSCH#2 is no longer mapped to PDSCH#2; the third symbol is symbols 10 to 13 in slot #1, and symbol 0 in slot #2.

[0252] For example, PDSCH#1 is mapped to symbols 0 to 13 in time slot #1, and PDSCH#2 is mapped to symbols 0 to 13 in time slot #2. Each time slot still has 14 symbols, and time slot #1 precedes time slot #2. The beams corresponding to PDSCH#1 and PDSCH#2 are different. The first threshold is 5, meaning the number of symbols switching beams is 5. However, the number of symbols between PDSCH#1 and PDSCH#2 is 0. Therefore, PDSCH#1 is no longer mapped to the 5 symbols in time slot #1 corresponding to PDSCH#1, or PDSCH#2 is no longer mapped to the 5 symbols in time slot #2 corresponding to PDSCH#2, or PDSCH#1 is no longer mapped to Q symbols in time slot #1 corresponding to PDSCH#1, and P symbols in time slot #2 corresponding to PDSCH#2, where Q is a positive integer greater than 0, P is also a positive integer greater than 0, and the sum of Q and P is 5. In this case, the third symbol only includes the second symbol, which can be the last 5 symbols of time slot #1, or the first 5 symbols of time slot #2, or the last Q symbols of time slot #1 and the first P symbols of time slot #2.

[0253] The above description can also be understood as follows: the first threshold is L, where L is a positive integer greater than 0. Specifically, the last Q symbols corresponding to PDSCH#1 are no longer mapped to PDSCH#1, and the first P symbols corresponding to PDSCH#2 are no longer mapped to PDSCH#2. PDSCH#1 precedes PDSCH#2, and there are no other PDSCH symbols between PDSCH#1 and PDSCH#2, nor are there any symbols without data between PDSCH#1 and PDSCH#2. In this case, the sum of M and P equals L, where M is a positive integer equal to or greater than 0, and P is also a positive integer equal to or greater than 0.

[0254] In this application, the third symbol can also be called a switching symbol. The third symbol can be located at the end of the previous time unit or at the beginning of the current time unit, or it can be located at both the end of the previous time unit and the beginning of the current time unit. This application does not limit this.

[0255] The above is merely an illustrative example. Anything that conveys the above meaning falls within the scope of protection of the embodiments of this application. The embodiments of this application will not be listed one by one.

[0256] The above exemplary description illustrates that when two adjacent PDSCH beams in the time domain are different, the number of symbols without data between the two PDSCHs is compared with a first threshold. When the number of symbols without data is greater than the first threshold, it can be implemented in the existing way, and the embodiments of this application will not be described in detail.

[0257] In one possible implementation, the network device can also inform the terminal device of the beam switching location. For example, the base station may be configured with a beam switching mode, that is, some PDSCHs use beam #1 and some PDSCHs use beam #2. The beam switching location is generally before the third symbol, which is used to indicate that the beam has started to change.

[0258] For example, PDSCH#1 corresponds to beam #1, PDSCH#2 corresponds to beam #2, and PDSCH#1 and PDSCH#2 are adjacent. Figure 6 As shown, D1 represents the symbol mapped to PDSCH#1 on time slot #1, and D2 represents the symbol mapped to PDCSH#2 on time slot #2. S=0, L=11 for PDSCH#1, and S=3, L=13 for PDSCH#2. The beam switching symbol occupies 5 symbols, located at symbols 12 and 13 in time slot #1, and symbols 0 to 2 in time slot #2. The switching position is located at the end of symbol 11 in time slot #1, or at the beginning of symbol 12, that is, before the third symbol. The third symbol is the switching symbol, and the switching position indicates the start of switching from beam #1 to beam #2.

[0259] When the number of unmapped data symbols between two adjacent PDSCHs in the time domain is greater than the number of symbols required for beam switching, the switching position can be as follows: Figure 7 As shown. For example, PDSCH#1 and PDSCH#2 are connected. D1 is used to represent the symbol mapped to PDSCH#1 in time slot #1, and D2 is used to represent the symbol mapped to PDSCH#2 in time slot #2. PDSCH#1 has S=0 and L=7, while PDSCH#2 has S=5 and L=13. The number of unmapped data symbols between the two PDSCHs is 11, while the number of symbols required for beam switching is 5, and it is located at symbol 13 in time slot #1. Symbols 0 to 3 in time slot #2 are also required. The beam switching position is at the beginning of symbol 13 in time slot #1, or before the third symbol; the third symbol is the switching symbol.

[0260] In one possible implementation, the PDSCH may also carry RS, for example, DMRS. When the number of unmapped data symbols between two adjacent PDSCHs in the time domain is less than the number of symbols required for beam switching, the PDSCH may not be mapped on the last few symbols of the previous PDSCH, or it may not be mapped on the first few symbols of the current PDSCH, or some symbols may not be mapped on the previous PDSCH and some may not be mapped on the current PDSCH. In the latter two cases, the phenomenon that may occur is that the symbols originally used to map the reference signal become switching symbols, that is, the reference signal is no longer mapped on the symbols that originally mapped the reference signal. For the current PDSCH, it ultimately does not carry the reference signal, so the mapping position of the reference signal is changed, and it can be mapped on the Nth symbol after the third symbol.

[0261] For example, such as Figure 8 As shown, PDSCH#1 and PDSCH#2 are connected. D1 is used to represent the symbol mapped to PDSCH#1 on time slot #1, and D2 is used to represent the symbol mapped to PDSCH#2 on time slot #2. PDSCH#1 has S=0 and L=13, while PDSCH#2 has S=3 and L=13. The number of symbols required for beam switching is 5, and symbol 3 of time slot #2 is selected as the switching symbol. However, symbol 3 was originally used to map RS. Therefore, RS can be mapped on the first symbol after the third symbol, that is, on symbol 4.

[0262] For example, such as Figure 9 As shown, PDSCH#1 and PDSCH#2 are connected. D1 represents the symbol mapped to PDSCH#1 in time slot #1, and D2 represents the symbol mapped to PDSCH#2 in time slot #2. PDSCH#1 has S=0 and L=13, while PDSCH#2 has S=3 and L=13. Five symbols are required for beam switching. The switching position is between symbols 12 and 13 in time slot #1. There are no symbols for mapping RS in time slot #2. In other words, if there is no previously mapped RS in the time slot after the beam switching position, the RS is mapped to the Nth symbol after the third symbol. For example, if there is no previously mapped RS in time slot #2 in Figure D, the RS is mapped to symbol 4 in time slot #2, which is the first symbol after the third symbol.

[0263] The above is merely an illustrative example. Any PDSCH that has no RS symbol in its time unit after the switchover and for which an RS mapping symbol has been added falls within the scope of protection of this application. No further limitations are imposed.

[0264] In one possible implementation, the time unit where PDSCH resides may also need to map other signals. If so, the symbol that needs to be mapped to other signals becomes a switching symbol (third symbol), and in this case, other signals are no longer mapped. For example, if the other signal is a control resource set (CORESET), and the third symbol contains a symbol that should be mapped to CORESET, then the CORESET is no longer mapped to the symbol originally used to map the CORESET.

[0265] The above process describes how network devices map PDSCHs. As for the process of terminal devices receiving PDSCHs, existing technologies can be referenced. However, when receiving different and temporally adjacent PDSCHs, because there is a switching symbol between any two different and adjacent PDSCHs, the terminal device can accurately receive each PDSCH and accurately decode the mapped PDSCHs.

[0266] In this embodiment, since both the terminal device and the network device know the PDSCH mapping rules, when two adjacent PDSCH beams are different in the time domain, they know whether the symbols required for beam switching occupy the PDSCH symbols to be mapped. Thus, both have a consistent understanding of the symbols of the actual mapped PDSCH, which is beneficial to improving the reception performance of PDSCH.

[0267] The above description will be explained in detail below using PUSCH mapping as an example. The following description uses time slots as the time unit.

[0268] For PUSCH, when a terminal device sends data to a network device, the terminal device needs to map PUSCH on time-frequency resources. This application mainly uses mapping PUSCH in the time domain as an example for illustration.

[0269] The process of mapping PUSCH on a time unit by a terminal device is similar to the process of mapping PDSCH on a time unit by a network device. The mapping of PUSCH can be performed with reference to the above description. For the sake of brevity, only the differences between the two will be introduced below.

[0270] The terminal device needs to receive resource indication information for each PUSCH from the network device. For example, the terminal device receives the SLIV corresponding to each PUSCH. At this point, the terminal device can determine whether the beams of two adjacent PUSCHs are the same. The determination that the beams are different can be made in the following way:

[0271] Method 1:

[0272] If two adjacent PUSCHs correspond to different default beams, the terminal device can determine that the two PDSCHs correspond to different beams.

[0273] For example, if PUSCH#1 and PUSCH#2 are adjacent in the time domain, and the default beam of PUSCH#1 is beam 1, while the default beam of PUSCH#2 is beam 2, then beam 1 and beam 2 are different beams, meaning the default beams of PUSCH#1 and PUSCH#2 are different. If beam 1 and beam 2 are the same beam, then the default beams of PUSCH#1 and PUSCH#2 are the same. If only PUSCH#1 is mapped on time slot #1 and only PUSCH#2 is mapped on time slot #2, then the beams corresponding to PUSCH#1 and PUSCH#2 are different, which can also be understood as the beams corresponding to time slot #1 and time slot #2 being different.

[0274] Method 2:

[0275] Terminal devices can also determine that adjacent PUSCHs correspond to different beams by observing the beam switching location. This beam switching location can be obtained by the network device sending signaling. When the terminal device knows the beam switching location, it can determine which two PUSCHs will switch beams.

[0276] The above is merely an exemplary description of determining that the beams corresponding to two adjacent PUSCHs in the time domain are different. Any ability of a network device to determine that the beams corresponding to two adjacent PUSCHs in the time domain are different falls within the protection scope of this application. Therefore, this application will not list and describe them one by one.

[0277] For details on how the terminal device determines which symbols to map the PUSCH, whether the symbols to be mapped PUSCH need to be occupied, and the determination of the switching position, please refer to the above description of PDSCH. Therefore, we will not go into detail here.

[0278] Figure 10 This is a flowchart illustrating another resource mapping method proposed in this application, as shown below. Figure 10 As shown, the method may include steps S1010 to S1030. Each step is described in detail below.

[0279] S1010, the network device maps the first physical downlink shared channel (PDSCH) on the first time unit, and the beam corresponding to the first PDSCH is the same as the first beam.

[0280] S1020, the network device sends a signal on the first PDSCH.

[0281] S1030, the terminal device processes the received signal.

[0282] For example, a detailed description will be given using the scheduling of PDSCH as an example. The following description uses time units as time slots.

[0283] For example, a time unit can be a symbol, a mini-slot, a slot, or a subframe. This application does not limit this, but in the embodiments of this application, a time unit will be used as a slot for description. For the implementation process of other time units, please refer to the embodiments of this application.

[0284] Network devices can map PDSCH on time-frequency resources to send data to receiving devices. This application embodiment uses mapping PDSCH in the time domain as an example for illustration.

[0285] The network device first determines the airspace in which to transmit, or in other words, determines the beam to transmit the PDSCH. This beam can also be understood as spatial filtering, QCL assumption, or TCI state, etc. In this application, a beam (hereinafter referred to as the first beam) is specified. The beam corresponding to the PDSCH is compared with the first beam. If the beam corresponding to the PDSCH is the same as the first beam, the PDSCH can be mapped in the first time unit; otherwise, the PDSCH is not mapped in the first time unit.

[0286] In one possible implementation, the first beam includes a second beam and a third beam. The second beam includes the beam corresponding to the first indication information or a pre-configured beam, and the third beam includes the beam corresponding to the first indication information, the beam indicated by the first indication information, or a pre-configured beam. The first indication information is used to indicate the scheduling of the PDSCH; for example, it can be a DCI.

[0287] It should be understood that the determination of the second beam can be predefined by the protocol, that is, both the terminal device and the network device are predefined, or the network device can inform the terminal device through signaling, which includes but is not limited to RRC signaling.

[0288] In one possible implementation, before the end of the first time unit (or the first resource), if the network device determines that the beam corresponding to the PDSCH is the same as the second beam, then the PDSCH is mapped on the first time unit; or if the network device determines that the beam corresponding to the PDSCH is different from the second beam, then the PDSCH is not mapped on the first time unit. The first time unit is associated with the terminal device's processing time.

[0289] In one possible implementation, when the first time unit is after the end of the first duration, if the network device determines that the PDSCH has high priority and the beam corresponding to the PDSCH is the same as the third beam, then the PDSCH is mapped in the first time unit; or, if the network device determines that the PDSCH has high priority and the beam corresponding to the PDSCH is different from the third beam, then the PDSCH is not mapped in the first time unit.

[0290] For example, each time unit can be mapped to the same PDSCH or different PDSCHs. Each time unit can be mapped to one PDSCH or multiple PDSCHs. When mapping multiple PDSCHs, the individual PDSCHs can be the same or different. The following will use time units as time slots, with one PDSCH mapped to each time slot. It is important to note that in the following description, it is common to see time slots having the same or different beams. This can be understood as the PDSCHs having the same beam or different beams corresponding to the PDSCHs. For example, if time slot #1 is mapped to PDSCH #1 and time slot #2 is mapped to PDSCH #2, the beams of time slots #1 and #2 are different. This can be understood as the beam corresponding to PDSCH #1 being different from the beam corresponding to PDSCH #2. Figure 11 As shown, in Figure 11 The diagram shows a total of 9 time slots. The position between time slot #6 and time slot #7 is the beam switching position. K0 is the interval between the time slot where the DCI is located and its scheduling PDSCH. The QCL duration can be equivalent to the first duration. The position between time slot #6 and time slot #7 can also be called the end position of the first duration.

[0291] The first duration is related to the processing time of the terminal device. It can be considered that the first duration is the time taken for the terminal device to receive the DCI of the scheduling PDSCH, decode it, and switch to the beam indicated by the DCI after the decoding is completed.

[0292] In this application, a detailed explanation is given using the example of transmitting DCI with beam #1, where the beam corresponding to DCI is beam #1, DCI indicates beam #2, the beam specified during the QCL duration is the beam corresponding to DCI, i.e., beam #1, and the specified direction at the end of the QCL duration is the direction indicated by DCI.

[0293] The beam specified during the QCL duration can be the beam corresponding to a specific time slot, i.e., the beam corresponding to the PDSCH mapped on a specific time slot. For example, if PDSCH #3 is mapped on time slot #3, then it can be the beam corresponding to time slot #3, or it can be a pre-configured beam, such as beam #4, etc. The beam after the QCL duration ends can be the beam indicated by the DCI. If the DCI does not indicate a beam, it can also be the beam corresponding to the DCI, a pre-configured beam, or the beam corresponding to the PDSCH mapped on a specific time slot, etc.

[0294] To better distinguish between the beams before and after the end of the QCL duration, the beams defined before the end of the QCL duration can be considered as the second beams, and the beams defined after the end of the QCL duration can be considered as the third beams.

[0295] The second and third beams can be the same or different, depending on the actual situation. This application does not limit this.

[0296] The selection of the specified beam can be configured by higher layers for terminal and network devices, can be predefined by the protocol, or the network device can configure multiple beams and inform the terminal device through RRC signaling, etc. This application embodiment does not impose too many limitations on this.

[0297] For example, Figure 11 In the above, time slot #1 is mapped to PDSCH #1, and its corresponding beam is beam #1; time slot #2 is mapped to PDSCH #2, and its corresponding beam is beam #1; time slot #3 is mapped to PDSCH #3, and its corresponding beam is beam #3; time slot #4 is mapped to PDSCH #4, and its corresponding beam is beam #4; time slot #5 is mapped to PDSCH #5, and its corresponding beam is beam #1; time slot #6 is mapped to PDSCH #6, and its corresponding beam is beam #1; time slot #7 is mapped to PDSCH #7, and its corresponding beam is beam #2; time slot #8 is mapped to PDSCH #8, and its corresponding beam is beam #1; time slot #9 is mapped to PDSCH #9, and its corresponding beam is beam #2.

[0298] Each time slot can be mapped with the same PDSCH or with different PDSCHs. That is, among multiple PDSCHs, any two time slots can have the same or different PDSCHs mapped to them. This application does not impose further limitations on this.

[0299] For network devices, the beam of each PDSCH can be compared with a specified direction. If the two are the same, the PDSCH can be mapped. If the two are different, the PDSCH is not mapped.

[0300] For example, taking the process of mapping PDSCH in a network device as an example, time slots #1 to #6 are all before the end of the QCL duration. Therefore, it is necessary to compare the PDSCH to be mapped in each time slot with beam #1. If they are the same, they are mapped; otherwise, they are not mapped. The beams of the PDSCH to be mapped in time slots #7 to #9 are compared with beam #2.

[0301] For example, if the beam of PDSCH#1 to be mapped in time slot #1 is the same as the specified beam #1, then PDSCH#1 can be mapped in time slot #1. If the beam of PDSCH#2 to be mapped in time slot #2 is the same as the specified beam #1, then PDSCH#2 can be mapped in time slot #2. If the beam of PDSCH#3 to be mapped in time slot #3 is different from the specified beam #1, then PDSCH#3 will not be mapped in time slot #3. If the beam of PDSCH#4 to be mapped in time slot #4 is different from the specified beam #1, then PDSCH#4 will not be mapped in time slot #4. If the beam of PDSCH#5 to be mapped in time slot #5 has the same direction as the specified beam #1, then PDSCH#5 can be mapped in time slot #5. If the beam of PDSCH#6 to be mapped in time slot #6 has the same direction as the specified beam #1, then PDSCH#6 can be mapped in time slot #6. If the beam of PDSCH#7 to be mapped in time slot #7 is in the same direction as the specified beam #2, then PDSCH#7 can be mapped in time slot #7. If the beam of PDSCH#8 to be mapped in time slot #8 is different from the specified beam #2, then PDSCH#8 will not be mapped in time slot #8. If the beam of PDSCH#9 to be mapped in time slot #9 is the same as the specified beam #2, then PDSCH#9 can be mapped in time slot #9.

[0302] The beams of the PDSCHs that need to be mapped in time slots #7 to #9 can be the beams corresponding to PDSCHs with higher priority, that is, comparing the beams corresponding to the higher priority PDSCHs with beam #2. Here, a higher priority PDSCH can refer to messages sent by network devices that have higher priority, such as system messages, ultra-reliable and low-latency communication (URLLC) messages, etc.

[0303] For the terminal device, after receiving the PDSCH, it compares the beam of each PDSCH with the specified direction. If the beams are the same, it knows that the PDSCH has been mapped and can decode the PDSCH. If the beams are different, it knows that the PDSCH has not been mapped or that the PDSCH being carried is not the one it needs, and therefore will not receive or decode it.

[0304] For example, when a terminal device receives a PDSCH, it receives it according to its corresponding direction. That is, when receiving PDSCH#1, it receives it on beam #1; when receiving PDSCH#2, it receives it on beam #1; when receiving PDSCH#3, it receives it on beam #3. In other words, beam switching occurs between receiving PDSCH#2 and PDSCH#3. Similarly, when receiving PDSCH#4, it receives it on beam #4. Beam switching also occurs between receiving PDSCH#3 and PDSCH#4. The same applies to the following PDSCHs. It can also be understood as receiving according to the default beam for each PDSCH. When the default beam is different, beam switching occurs. It is important to note that the terminal device does not know whether PDSCHs are mapped on time slots #3 and #4 when receiving PDSCH#3 and PDSCH#4 respectively; it simply receives the PDSCHs. Then, it compares the received beam with the specified beam to confirm whether the PDSCHs are mapped.

[0305] For example, if it receives PDSCH#1 in beam #1, and the received beam is the same as the specified beam, then it can be confirmed that PDSCH#1 is mapped in time slot #1. If it receives time slot #3 in beam #3, and the received beam is different from the specified beam, then it can be confirmed that PDSCH#2 is not mapped in time slot #3. The same judgment is made as for whether other time slots are mapped to PDSCH. For the sake of simplicity, this application embodiment will not list them one by one.

[0306] In one possible implementation, the terminal device may also consider the offset (e.g., K0) to be related to the beam switching capability, which includes, but is not limited to, the QCL duration. That is, the terminal device considers K0 to occur in X units of beam switching, where X is an integer. If X is greater than 0, K0 is considered to occur in X time units after beam switching. If X is less than 0, K0 is considered to occur in X time units before beam switching. If X is equal to 0, K0 is considered to occur in the current time unit of beam switching.

[0307] In another possible implementation, the protocol may also stipulate that the terminal device does not consider the beam of the PDSCH to change over multiple time units; that is, the terminal device will only use the same receiving beam to receive the PDSCH.

[0308] In another possible implementation, a second indication information is obtained, which is used to indicate that the beam corresponding to the first PDSCH is different from the beam corresponding to the PDSCH (third PDSCH or second PDSCH) transmitted at the previous moment.

[0309] The second indication information can be configured by higher-layer signaling or the physical layer. When a network device or terminal device obtains this second indication information, it knows that the beam corresponding to the first PDSCH is different from the beam corresponding to the PDSCH (third PDSCH) scheduled at the previous moment, and needs to further determine whether the first PDSCH and the first beam are the same. Alternatively, after obtaining this second indication information, the terminal device and network device can clearly know whether to use the mapping rules mentioned above to map the resources.

[0310] For multi-slot PDSCH scheduling, it can also be combined with... Figure 2 The corresponding embodiments are combined, but the embodiments of this application do not limit them in too much.

[0311] In the above scheme, the default beam of PDSCH is compared with the specified beam to determine whether PDSCH should be mapped. Both the terminal device and the network device decode and map PDSCH according to this rule, which helps to avoid frequent beam switching and allows the terminal device and the network device to have the same understanding of PDSCH resource mapping.

[0312] It's important to understand that protocols can predefine various mapping rules; for example, network devices and terminal devices may be configured with different mapping rules. Figure 2 The resource mapping rules corresponding to method 200 have also been configured. Figure 10 The mapping rule corresponding to method 100 may also be configured with other resource mapping rules. In this case, the network device can send indication information to the terminal device, instructing it to use which set or sets of resource mapping rules for mapping. Specifically, the network device sends RRC signaling to the terminal device. This application embodiment does not impose excessive limitations on which set or sets of mapping rules are specifically used. The above is through... Figures 2 to 11 The resource scheduling method has been explained in detail. The following will combine...

The communication device 1300 includes a transceiver module 1310 and a processing module 1320. The processing module 1320 is used for data processing, and the transceiver module 1310 can implement corresponding communication functions.

The beams corresponding to the first data channel and the second data channel are different. The first data channel is mapped to symbols in the first to be mapped symbols except for at least one second symbol, and / or the second data channel is mapped to symbols in the second to be mapped symbols except for at least one second symbol.
