Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] A power amplifier (PA) can amplify low-power signals generated by network devices or terminal devices to a power level that can be transmitted over long distances, and is a core component of wireless communication equipment.

[0003] Due to factors such as transistor manufacturing processes, the self-heating of active power devices, the input signal envelope frequency bandwidth and bias, and the design quality of the matching network, a significant memory effect occurs when broadband orthogonal frequency division multiplexing (OFDM) signals pass through a power amplifier (PA). The most prominent manifestation is the asymmetry between the adjacent channel leakage ratio (ACLR) on the left and right sides of the channel bandwidth, meaning an asymmetry in spurious power between adjacent channels. To suppress the spurious power of adjacent channels to the same level, the maximum transmit power within the channel bandwidth differs between the left and right sides. In other words, when a network device scheduling terminal transmits within the channel bandwidth, the spurious power in an adjacent channel with a lower ACLR when the scheduling resource is closer to that channel is greater than the spurious power in an adjacent channel with a higher ACLR when the scheduling resource is closer to that channel.

[0004] Currently, during the uplink transmission of terminal devices, network devices do not determine resource allocation based on the type of memory effect of the terminal. If a network device schedules a terminal to transmit near a channel with a lower ACLR (Advanced Channel Limiting Ratio), the higher spurious power of this adjacent channel leads to a larger maximum power backoff value, resulting in a lower maximum transmit power. Conversely, when a network device schedules a terminal to transmit near a channel with a higher ACLR, the lower spurious power allows the terminal to use a smaller maximum power backoff value, resulting in a higher maximum transmit power. Therefore, scheduling a terminal to transmit near a channel with a lower ACLR reduces its maximum transmit power compared to scheduling a terminal to transmit near a channel with a higher ACLR. Therefore, how to rationally allocate resources to improve the maximum transmit power of the terminal is a pressing technical problem that needs to be solved. Summary of the Invention

[0005] This application provides a communication method and apparatus for rationally allocating resources to improve the maximum transmission power of a terminal.

[0006] In a first aspect, embodiments of this application provide a communication method, which can be executed by a first device. Unless otherwise specified, the "first device" in this application can refer to the first device itself (e.g., a terminal device), a component within the first device (e.g., a functional module, communication module, processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first device. Taking a terminal device as an example, the method includes: the first device sending first information, the first information indicating that the power of the terminal device in a first adjacent channel is lower than the power of the terminal device in a second adjacent channel; or, the first information indicating that the power of the terminal device in the second adjacent channel is lower than the power of the terminal device in the first adjacent channel; wherein the frequency of the first adjacent channel is lower than the frequency of the second adjacent channel; the terminal device receiving scheduling information, the scheduling information indicating the transmission resources of the terminal device, the scheduling information being determined based on the first information.

[0007] In other words, the first piece of information can be used to indicate the type of memory effect of the terminal device.

[0008] Based on this implementation, the first information can be used to indicate the type of memory effect of the terminal device, where the memory effect causes the spurious power of the terminal in the left adjacent channel to be different from that in the right adjacent channel. It is understood that if the spurious power of the two adjacent channels is to be suppressed to the same level, power suppression of the terminal's transmission power needs to be performed based on the larger spurious power, resulting in a reduction in the terminal's transmission power. Based on the method of this application, the second communication device can reasonably determine the terminal's transmission resources based on the first information (or based on the type of memory effect of the terminal device indicated by the first information), avoiding channel bandwidth scheduling of the terminal in the adjacent channel near the side with larger spurious power. This can reduce spurious power, thus the terminal does not need to suppress transmission power excessively, thereby increasing the terminal's maximum transmission power.

[0009] In one possible implementation, the scheduling information is determined based on the first information, including: the transmission resources are determined based on the first information and the channel bandwidth.

[0010] Based on this implementation, the second communication device can flexibly determine the transmission resources of the terminal device according to the first information and the channel bandwidth of the first communication device or the bandwidth of the network device.

[0011] In one possible implementation, the scheduling information is determined based on the first information, including: the transmission resources are determined based on the first information and the bandwidth of the network device.

[0012] Based on this implementation, the second communication device can flexibly determine the transmission resources of the terminal device according to the first information and the bandwidth of the network device.

[0013] In one possible implementation, the transmission resource is determined based on the first information and the channel bandwidth, including: the transmission resource is determined based on at least one of an outer left resource region, an outer right resource region, an internal resource region, and an edge resource region, and the first information, wherein at least one of the outer left resource region, the outer right resource region, the internal resource region, and the edge resource region is determined based on the channel bandwidth.

[0014] It is understood that in this application, "left" represents a low frequency and "right" represents a high frequency.

[0015] Based on this implementation, the second communication device can determine at least one of the external left resource region, external right resource region, internal resource region, and edge resource region according to the channel bandwidth of the terminal device, and determine the transmission resources of the terminal device according to the above at least one region and the first information. For example, the second communication device can determine the transmission resources of the terminal device from at least one of the external left resource region, external right resource region, internal resource region, and edge resource region according to the first information. Here, the external left resource region, external right resource region, internal resource region, and edge resource region all belong to the channel bandwidth.

[0016] In one possible implementation, the number of resource blocks in the outer right-side resource region that have a frequency higher than the center frequency of the channel bandwidth is greater than the number of resource blocks that have a frequency lower than the center frequency of the channel bandwidth. Additionally, in the outer left-side resource region, the number of resource blocks that have a frequency lower than the center frequency of the channel bandwidth is greater than the number of resource blocks that have a frequency higher than the center frequency of the channel bandwidth.

[0017] After simulation and real signal testing, if the memory effect of the terminal device is right, or if the first information indicates that the type of memory effect is right, or if the first information is used to indicate that the power of the terminal device in the second adjacent channel is lower than the power of the terminal device in the first adjacent channel, or if the first information is used to indicate that the ACLR of the terminal device in the second adjacent channel is higher than the ACLR of the terminal device in the first adjacent channel, the second communication device allocates transmission resources to the terminal device from the external right resource area, which can effectively reduce the power of the terminal device in the first adjacent channel. Here, the first adjacent channel is the adjacent channel corresponding to the higher power, so the power backoff value used to suppress the power of the adjacent channel can be reduced, which is equivalent to increasing the maximum transmit power of the terminal device.

[0018] If the memory effect of the terminal device is left, or if the first information indicates that the type of memory effect is left, or if the first information is used to indicate that the power of the terminal device in the first adjacent channel is lower than the power of the terminal device in the second adjacent channel, or if the first information is used to indicate that the ACLR of the terminal device in the second adjacent channel is higher than the ACLR of the terminal device in the first adjacent channel, the second communication device allocates transmission resources to the terminal device from the external left resource area, which can effectively reduce the power of the terminal device in the second adjacent channel. The second adjacent channel is the adjacent channel corresponding to the higher power, so the power backoff value used to suppress the power of the adjacent channel can be reduced, which is equivalent to increasing the maximum transmit power of the terminal device.

[0019] In one possible implementation, the transmission resource is determined based on the first information and the bandwidth of the network device, including: the transmission resource is determined based on at least one of an external left resource region, an external right resource region, an internal resource region, and an edge resource region, and the first information; at least one of the external left resource region, the external right resource region, the internal resource region, and the edge resource region is determined based on the bandwidth of the network device. Wherein, the external left resource region, the external right resource region, the internal resource region, and the edge resource region all belong to the bandwidth of the network device.

[0020] Based on this implementation, the second communication device can determine at least one of the external left resource region, external right resource region, internal resource region, and edge resource region according to the bandwidth of the network device, and determine the transmission resources of the terminal device according to the above at least one region and the first information. For example, the second communication device can determine the transmission resources of the terminal device from at least one of the external left resource region, external right resource region, internal resource region, and edge resource region according to the first information.

[0021] In one possible implementation, the number of resource blocks in the outer right-side resource region that have a frequency higher than the center frequency of the network device's bandwidth is greater than the number of resource blocks that have a frequency lower than the center frequency of the network device's bandwidth. Conversely, the number of resource blocks in the outer left-side resource region that have a frequency lower than the center frequency of the network device's bandwidth is greater than the number of resource blocks that have a frequency higher than the center frequency of the network device's bandwidth.

[0022] Based on this implementation method, the power back-off value used to suppress adjacent channel power can be reduced, which is equivalent to increasing the maximum transmit power of the terminal device.

[0023] In one possible implementation, if the terminal's transmission resources belong to the external left-side resource area, the first communication device can further determine the terminal's maximum power back-off information and / or power consumption reduction value for that transmission resource based on the operator information of the first adjacent channel. If the terminal's transmission resources belong to the external right-side resource area, the first communication device can further determine the terminal's maximum power back-off information and / or power consumption reduction value for that transmission resource based on the operator information of the second adjacent channel.

[0024] Based on this implementation, the terminal device can determine the maximum power backoff information based on the operator information of adjacent channels to increase the maximum transmit power. Furthermore, the terminal device can also determine the transmit power consumption based on the operator information of adjacent channels to reduce transmit power consumption.

[0025] In one possible implementation, the external left resource region and the external right resource region are located in the external resource region within the channel bandwidth or the bandwidth of the network device.

[0026] In one possible implementation, the first information, used to indicate that the power of the terminal device in the first adjacent channel is lower than the power of the terminal device in the second adjacent channel, includes: the first information includes type information of the memory effect of the power amplifier of the terminal device, the type information indicating that the type of the memory effect is left-handed. Alternatively, the first information can be used to indicate that the type of the memory effect is left-handed.

[0027] In one possible implementation, the first information, used to indicate that the power of the terminal device in the second adjacent channel is lower than the power of the terminal device in the first adjacent channel, includes: the first information includes type information of the memory effect of the power amplifier of the terminal device, the type information indicating that the type of the memory effect is right-handed. Alternatively, the first information can be used to indicate that the type of the memory effect is right-handed.

[0028] Optionally, the memory effect corresponding to the power of the first adjacent channel being lower than the power of the terminal device in the second adjacent channel can also be of type right, and the memory effect corresponding to the power of the second adjacent channel being lower than the power of the terminal device in the first adjacent channel can be of type left.

[0029] In one possible implementation, the first communication device may also send second information, which indicates the frequency band corresponding to the first information, wherein the frequency band corresponding to the first information is all frequency bands, a combination of one or more frequency bands, or one or more frequency bands.

[0030] Based on this implementation, the first communication device can report the frequency band applicable to the memory type to the second communication device, enabling the second communication device to allocate transmission resources to the terminal device in the corresponding frequency band according to the first information. It can be understood that the terminal device can correspond to different memory effect types in different frequency bands, thereby achieving flexible resource scheduling based on the memory effect type of the terminal device in different frequency bands.

[0031] In one possible implementation, the first communication device may also send third information, which indicates the power level corresponding to the first information.

[0032] Based on this implementation, the first communication device can report the power level applicable to the memory type to the second communication device, enabling the second communication device to allocate transmission resources to the terminal device according to the first information at the corresponding power level. It can be understood that the terminal device can correspond to different memory effect types at different power levels, thereby achieving flexible resource scheduling based on the type of memory effect of the terminal device at different power levels.

[0033] In one possible implementation, the first communication device may also determine the maximum power back-off information of the terminal device on the transmission resource based on the first information.

[0034] Based on this implementation, the first communication device can determine the maximum power backoff information according to the first information. Alternatively, the first communication device can determine the maximum power backoff information based on the type of memory effect. Specifically, when the terminal sends the first information, and / or when the second communication device allocates transmission resources to the terminal device based on the first information, it can suppress the power of adjacent channels with higher power. Therefore, the first communication device can use a smaller maximum power backoff information when transmitting on that transmission resource to increase the maximum transmit power. As an example, if the terminal device's transmission resource is located within an external resource block allocation area, the first communication device can subtract x decibels from the maximum power backoff value defined in the current protocol to obtain the final maximum power backoff value; that is, the maximum power backoff information is reduced by x decibels from the protocol definition.

[0035] In one possible implementation, the maximum power backoff information corresponds to the channel bandwidth or the bandwidth of the network device.

[0036] Based on this implementation, the first communication device can use different maximum power backoff information for different channel bandwidths or network device bandwidths, thereby flexibly determining the maximum transmit power. For example, different x values ​​can be used for different channel bandwidths or network device bandwidths.

[0037] In one possible implementation, the first communication device may also determine the power consumption reduction value of the terminal device based on the first information.

[0038] Based on this implementation, the first communication device can determine a power reduction value based on the first information to reduce power consumption. For example, a power reduction value p can be set, with the unit being joules per bit. When the first communication device sends the first information, and / or when the second communication device allocates transmission resources to the terminal device based on the first information, the first communication device can reduce power consumption by p joules per bit when transmitting using those transmission resources.

[0039] In one possible implementation, this power reduction corresponds to the channel bandwidth or the bandwidth of the network device.

[0040] Based on this implementation, the first communication device can adopt different power reduction values ​​for different channel bandwidths or network device bandwidths, thereby flexibly determining the transmission power consumption. For example, different power reduction values ​​can be adopted for different channel bandwidths or network device bandwidths.

[0041] In one possible implementation, the first communication device may also send fourth information, which indicates the difference between the power of the terminal device in the first adjacent channel and the power of the terminal device in the second adjacent channel, and the difference is used to determine the scheduling priority of the terminal device.

[0042] Based on this implementation, the first communication device can indicate the difference between the power of the first adjacent channel and the power of the second adjacent channel to the second communication device, so that the second communication device can determine the scheduling priority of the terminal based on the difference. It can be understood that the second communication device can prioritize scheduling terminals with a larger difference between the power of the first adjacent channel and the power of the second adjacent channel to achieve a better effect of increased transmission power.

[0043] In one possible implementation, the difference and the scheduling priority satisfy one or more of the following: the difference is greater than a first threshold, and the scheduling priority is higher than the priority corresponding to the first threshold; or, when the difference belongs to a first power range, the scheduling priority is the first scheduling priority corresponding to the first power range, and when the difference belongs to a second power range, the scheduling priority is the second scheduling priority corresponding to the second power range, where the power in the second power range is greater than the power in the first power range, and the second scheduling priority is higher than the first scheduling priority.

[0044] Secondly, embodiments of this application provide a communication method, which can be executed by a second device. Unless otherwise specified, the "second device" in this application can refer to the second device itself (e.g., a network device such as a base station), a component within the second device (e.g., a functional module, communication module, processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second device. The method includes: a second communication device receiving first information, the first information indicating that the power of a terminal device in a first adjacent channel is lower than the power of the terminal device in a second adjacent channel, or the first information indicating that the power of the terminal device in the second adjacent channel is lower than the power of the terminal device in the first adjacent channel; wherein the frequency of the first adjacent channel is lower than the frequency of the second adjacent channel; the second communication device can also determine the transmission resources of the terminal device based on the first information and send scheduling information, the scheduling information indicating the transmission resources.

[0093] In one possible implementation, the communication unit (or receiving unit) may also receive fourth information, which indicates the difference between the power of the terminal device in the first adjacent channel and the power of the terminal device in the second adjacent channel; the processing unit may use this difference to determine the scheduling priority of the terminal device.

[0094] In one possible implementation, the difference and the scheduling priority satisfy one or more of the following: the difference is higher than a first threshold, and the scheduling priority is higher than the priority corresponding to the first threshold; or, when the difference is within a first power range, the scheduling priority is the first scheduling priority corresponding to the first power range, and when the difference is within a second power range, the scheduling priority is the second scheduling priority corresponding to the second power range, where the power in the second power range is greater than the power in the first power range, and the second scheduling priority is higher than the first scheduling priority.

[0097] In one possible implementation, the processor and memory are integrated together;

[0098] In another possible implementation, the memory is located outside the communication device.

[0099] The communication device also includes a communication interface for communicating with other devices, such as sending or receiving data and / or signals. Exemplarily, the communication interface may be a transceiver, circuit, bus, module, or other type of communication interface.

[0103] Eighthly, a chip system is provided, comprising logic circuitry (or, as understood, a processor, which may include logic circuitry, etc.), and further comprising input / output interfaces. The input / output interfaces can be used to input messages or to output messages. The input / output interfaces can be the same interface, i.e., the same interface can implement both sending and receiving functions; or, the input / output interface includes an input interface and an output interface, the input interface being used to implement the receiving function, i.e., to receive messages; and the output interface being used to implement the sending function, i.e., to send messages. The logic circuitry can be used to perform operations other than the sending and receiving functions in any possible implementation of any of the first to second aspects described above; the logic circuitry can also be used to transmit messages to the input / output interfaces or to receive messages from other communication devices from the input / output interfaces.

[0122] The specific implementation of this application will be described below with reference to the accompanying drawings in the embodiments of this application.

[0123] The embodiments of this application can be applied to various communication systems. For example, communication systems may include cellular systems such as Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunications System (UMTS), 5th Generation (5G), or New Radio (NR), or may be applied to future communication systems or other similar communication systems. Alternatively, communication systems may include non-cellular systems such as Ultra Wide Band (UWB), Worldwide Interoperability for Microwave Access (WIMAX), or WiFi.

[0124] Figure 1 A possible, non-limiting system schematic diagram is shown. For example... Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system may also include an Internet 300. The radio access network 100 may include at least one radio access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal (such as Figure 1(Referring to 120a-120j in the original text). Terminals connect wirelessly to the wireless access network (WLAN) equipment, which in turn connects to the core network via wireless or wired connections. The core network equipment and the WLAN equipment can be independent physical devices, or they can integrate the functions of the core network equipment and the logical functions of the WLAN equipment onto the same physical device. Alternatively, a single physical device can integrate some of the functions of both the core network equipment and the WLAN equipment. Terminals and WLAN equipment can be interconnected via wired or wireless connections. Figure 1 This is just an illustration; the communication system may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 It is not shown in the middle.

[0125] In this application, unless otherwise specified, access network equipment may be used to represent wireless access network equipment such as base stations.

[0126] Access network equipment can be a device in the RAN that provides priority and / or wireless communication functions for terminal equipment, referred to as RAN equipment or (R)AN equipment. RAN can be an access network in the 3rd generation partnership project (3GPP), such as 4th generation (4G), 5G, or future communication networks. RAN can also be an open access network (O-RAN or ORAN), a cloud radioaccess network (CRAN), or a communication network combining two or more of the above. RAN equipment can be a base station in a Long Term Evolution (LTE) or LTE Advanced (LTE-A) communication system, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation nodeB (gNB) in a 5th generation (5G) mobile communication system, a base station in a future mobile communication system, a wireless fidelity (WiFi) system, a long-range radio (LoRa) system, or an access node in a vehicle-to-everything (V2X) system. RAN equipment can also be a module or unit that performs some of the functions of a base station; for example, it can be a CU, a DU, a CU-user plane (UP), or a RU, etc. For example, a CU is configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); a DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and / or the Physical (PHY) layer). For detailed descriptions of the aforementioned protocol layers, please refer to the relevant 3GPP technical specifications. CUs and DUs can be configured separately or included in the same network element, such as a baseband unit (BBU).The RU can be included in radio frequency equipment or radio frequency units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. The wireless access network equipment can also be a macro base station (e.g.,...). Figure 1 110a), or micro base stations or indoor stations (such as...) Figure 1 110b) in the text can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment. For ease of description, the base station can be used as an example of a wireless access network equipment in this application.

[0127] In some examples, the CU can be split into CU-CP and CU-UP. CU-CP is a logical node carrying the RRC layer and the PDCP control plane (PDCP-C) layer, used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF network elements in a 5G system. CU-UP is a logical node carrying the SDAP layer and the PDCP-U (user plane part of PDCP) layer, used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above CU and DU configurations are merely examples; the functions of CU and DU can be configured as needed. For example, a CU or DU can be configured to have more protocol layer functions, or it can be configured to have only some protocol layer processing functions. For instance, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. As another example, the functions of the CU or DU can be divided according to service type or other system requirements. For instance, based on latency, functions that need to meet low latency requirements can be placed in the DU, while functions that do not need to meet this latency requirement can be placed in the CU.

[0128] In some examples, a DU can host logical nodes for the RLC layer, MAC layer, higher physical layer (higher PHY) layer, or other functionalities. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces.

[0129] In some examples, the CU may not have a PDCP layer, for example, it may only include the RRC layer. The CU-CP may not have PDCP-C. The CU-UP may not have PDCP-U, or may not have CU-UP at all. In some examples, the DU may not have an RLC layer, for example, it may only have MAC and higher physical layers. Furthermore, in some examples, the O-RAN device may also not have a CU and only include the DU, i.e., without an RRC layer.

[0130] In some examples, the higher physical layer includes portions of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation. In some examples, the RU is a logical node carrying both lower physical layer (lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP TRP or RRH or other similar entity. In some examples, the lower physical layer includes portions of the PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more terminals via a wireless link.

[0131] As an example, such as Figure 2 As shown, the access network device can communicate with the core network device via a backhaul link. The access network device can also communicate with user equipment (UE) via an air interface. This access network device can include a BBU and an RU, where the BBU can include a CU and a DU. The specific communication process can include: the BBU in the access network device communicating with the core network via the backhaul link, and / or, the RU in the access network device communicating with at least one terminal via the air interface. The BBU (such as a DU) can communicate with at least one RU via a fronthaul link. The BBU and RU can be co-located or not. The BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0132] It is understood that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open CU (O-CU), CU-CP can also be called an open CU-CP (O-CU-CP), CU-UP can also be called an open CU-UP (O-CU-UP), DU can also be called an open DU (O-DU), and RU can also be called an open RU (O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0133] In some examples, the CU (Control Unit) of an access network device is a logical node that carries the RRC (Resource Control Code) layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, and other control functions of the access network device. The CU connects to network nodes such as the core network through interfaces, which can be interfaces such as E2 interfaces. Optionally, the CU may have some core network functions. The CU (e.g., the PDCP layer and higher layers) connects to the DU (e.g., the Radio Link Control (RLC) layer and lower layers) through interfaces, which can be interfaces such as F1 interfaces. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, terminal context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the F1 signaling procedures in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0134] In some examples, the DU and RU may or may not be co-located. The DU and RU exchange control plane and user plane information via a lower-layer split-control, user, and synchronization (LLS-CUS) interface through a fronthaul link. LLS-CUS may include LLS-C and LLS-U interfaces providing C-Plane and LLS-C and LLS-U interfaces providing U-Plane, respectively. In some examples, C-Plane refers to real-time control between the DU and RU. The DU and RU exchange management information, such as management plane (M-Plane) management information, through an LLS-M interface on the fronthaul link. M-Plane refers to non-real-time management operations between the DU and RU. The DU and RU can cooperate to implement PHY layer functions. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways depending on the design. For example, the DU may be configured to implement baseband functions, and the RU may be configured to implement mid-RF functions. For example, DU is configured to implement higher-level functions in the PHY layer, and RU is configured to implement lower-level functions in the PHY layer, or to implement both lower-level functions and RF functions. Higher-level functions in the physical layer may include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer may include another portion of the physical layer's functions that are closer to the mid-RF side.

[0135] It is understood that the embodiments of this application do not limit the specific technology or device form used in the access network equipment. The access network equipment can be one or more of BBU, CU, DU, or RU. In addition, the CU can be classified as a network device in the access network or as a network device in the core network, and this application does not limit this.

[0136] In this application, a network device can be used to represent an access network device.

[0137] It is understood that a network device can be referred to as a communication device. For example, a network device can be understood as a device that has network device functions. For example, the device used to implement the functions of a network device can be the network device itself; or some components within the network device, such as CU, DU, or RU. The device used to implement the functions of a network device can also be a device capable of supporting the network device in implementing those functions, such as a chip system, hardware circuitry, software modules, or a combination of hardware circuitry and software modules. This device can be installed in the network device or can be used in conjunction with the network device. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete devices.

[0138] Terminal devices can also be called terminals or terminal equipment, UE, stations (STA), mobile stations (MS), mobile terminals (MT), etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc.

[0139] The embodiments of this application do not limit the specific technology or device form used in the terminal device. It is understood that the terminal device may be referred to as a communication device. For example, a terminal device can be understood as a device having terminal device functions. For example, the device used to implement the functions of the terminal device can be the terminal device itself; it can also be a device capable of supporting the terminal device in implementing those functions, such as a chip system, hardware circuit, software module, or hardware circuit plus software module. This device can be installed in the terminal device or can be used in conjunction with the terminal device.

[0140] Network devices and terminal devices can be fixed in location or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the network devices and terminal devices.

[0141] The roles of network devices and terminal devices can be relative, for example, Figure 1 The helicopter or drone 120i in the diagram can be configured as a mobile base station or access point (AP). For terminals 120j that access the wireless access network 100 via 120i, drone 120i is a network device; however, for network device 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Alternatively, 110a and 120i can also communicate via a network device-to-network device interface protocol; in this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. Figure 1110a and 110b can be referred to as communication devices with network equipment functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal equipment functions.

[0142] In this application, network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate using licensed spectrum, unlicensed spectrum (or unlicensed spectrum), or a combination of both. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0143] In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX. "Send information" can include direct transmission or indirect transmission through other communication devices, communication apparatuses, units, or modules. "Receive information from YY" can be understood as the source of the information being YY. "Receive information" can include direct reception from YY or indirect reception from YY through other communication devices, communication apparatuses, units, or modules. Furthermore, "send" can also be understood as the "output" of a chip interface, and "receive" can be understood as the "input" of a chip interface. In other words, "send" or "receive" can occur between devices, such as a base station and a terminal device transmitting or receiving data via an air interface. "Send" or "receive" can also occur within a device, such as transmitting or receiving data between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0144] In this application, "for indicating" can include both direct and indirect indication. When describing "information" for indicating A, it can include whether the information directly indicates A or indirectly indicates A, but does not necessarily mean that the information carries A.

[0145] The information indicated by a given piece of information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent. At the same time, common parts of various pieces of information can be identified and indicated uniformly to reduce the indication overhead caused by individually indicating the same information.

[0146] Furthermore, the specific indication method can also be any existing indication method, such as, but not limited to, the above-mentioned indication methods and their various combinations. Specific details of various indication methods can be found in existing technologies, and will not be repeated here. As described above, for example, when multiple pieces of information of the same type need to be indicated, the indication methods for different pieces of information may differ. In the specific implementation process, the required indication method can be selected according to specific needs. This application embodiment does not limit the selected indication method; therefore, the indication methods involved in this application embodiment should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated.

[0147] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device sending configuration information to the receiving device. Taking the configuration of a terminal by an access network device as an example, the configuration information can include, for example but not limited to, one or a combination of at least two of RRC signaling (or RRC messages), MAC layer signaling, and PHY layer signaling. MAC layer signaling includes, for example, a MAC control element (CE). PHY layer signaling includes, for example, at least one of downlink control information (DCI).

[0148] In the embodiments shown below, the first, second, and various numerical designations are merely distinctions for descriptive convenience and are not intended to limit the scope of the embodiments of this application. For example, they distinguish different indication information.

[0149] "Preset," "predefined," or "preconfigured" can be achieved by pre-storing corresponding codes, tables, or other means of indicating relevant information in the device (e.g., including terminal devices and network devices), or by pre-defining them in a protocol. This application does not limit the specific implementation method. "Stored" can refer to storing in one or more memories. These memories can be separate installations or integrated into the encoder, decoder, processor, or communication device. Alternatively, some memories can be separate installations, while others are integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application does not limit this.

[0150] The “protocol” mentioned in the embodiments of this application may refer to standard protocols in the field of communications, such as 3GPP’s LTE protocols (such as technical specification (TS) 36, i.e., the TS36 series of technical specifications), NR protocols (such as the TS38 series of technical specifications), and related protocols applied to future communication systems. This application does not limit this.

[0151] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0152] The technical terms and related technical solutions in this application will be described below with reference to the accompanying drawings.

[0153] 1) PA and its nonlinear transmission characteristics.

[0154] The power amplifier (PA) in the transmitter converts low-power signals into higher-power signals, overcoming signal attenuation between the transmitter and receiver and ensuring the receiver receives a sufficiently strong signal. The core semiconductor device of the PA is the transistor, which has non-linear characteristics. Therefore, the PA cannot maintain the ideal linearity expected by the transmitter. These non-linear characteristics cause harmonics and intermodulation distortion in the power amplifier. These distortions degrade the system's transmission performance, causing out-of-band radiated interference, increased bit error rate, and decreased error vector magnitude (EVM) performance. (Refer to...) Figure 3 The diagram shown is a nonlinear schematic of a power amplifier (PA). The horizontal axis represents the input power, and the vertical axis represents the output power. As the input power increases, the relationship between the input and output is no longer linear. Therefore, when the input power increases, the signal transmitted through the PA will experience nonlinear characteristics, causing nonlinear distortion of the signal.

[0155] Since the efficiency of a power amplifier (PA) is inversely related to its distortion, efficiency increases with increasing nonlinear distortion. This means that efficiency is gained by trading distortion for efficiency. Reducing the voltage will lead to an increase in nonlinear distortion. Therefore, the efficiency of a PA can be improved by reducing the voltage.

[0156] 2) ACLR and spectral emission mask (SEM)

[0157] The 3GPP protocol defines the values ​​of ACLR and SEM to constrain out-of-band power values ​​to not exceed a certain range.

[0158] ACLR is the ratio of the average power centered on a specified channel frequency to the average power centered on adjacent channel frequencies. If the measured adjacent channel power is greater than or equal to -50 dBm, the ACLR should be higher than the value specified in Table 1.

[0159] Table 1

[0160] Power level 1 Power rating 1.5 Power level 2 Power level 3 ACLR 37 decibels (dB) 31dB 31dB 30dB

[0161] SEM is applied to frequencies (Δ) starting from the positive edge of the allocated NR channel bandwidth (CBW). fOOB In this application, channel bandwidth is the bandwidth allocated by the network device to the terminal, within which the terminal device can perform reception and / or transmission. Each transmission or reception may occupy part or all of the channel bandwidth. The network device can schedule the terminal's transmission resources within the channel bandwidth. The power transmitted by any terminal device must not exceed the power level corresponding to the specified channel bandwidth as defined in Table 2. In Table 2, measurement bandwidth (MBW) represents the measurement bandwidth defined by the protected frequency band.

[0162] Table 2

[0163]

[0164] In Table 2, BWchannel represents the channel bandwidth.

[0165] The main difference between ACLR and SEM is that ACLR is a relative value, while SEM is an absolute value. What they have in common is that the requirements for adjacent channels on both sides of the channel bandwidth are symmetrical. In other words, adjacent channels on both sides of the channel bandwidth have the same spurious power requirements. Therefore, it is necessary to suppress the spurious power of adjacent channels on both sides of the channel bandwidth to the same level to avoid interference with other communication equipment on adjacent channels.

[0166] 3) Adjacent channels, or adjacent channels

[0167] In this application, adjacent channels refer to the bandwidth of the adjacent channels to the left or right of the terminal device's channel bandwidth considered during ACLR measurement. The width of these adjacent channels can be called the ACLR measurement bandwidth. The ACLR measurement bandwidth is related to the subcarrier spacing (SCS) and the terminal device's channel bandwidth. For example, the ACLR measurement bandwidth, subcarrier spacing, and terminal device's channel bandwidth satisfy the following:

[0168] ACLR measurement bandwidth = subcarrier spacing * (12 * N_RB + 1) / 1000;

[0169] Here, represents the number of RBs included in the channel bandwidth of the N_RB terminal. The number of RBs is related to the subcarrier spacing and the terminal's channel bandwidth, and can be found in the protocol definition.

[0170] Taking Table 3 as an example, when the channel bandwidth is 100MHz, if the subcarrier spacing is 30KHz, N_RB=273.

[0171] Table 3

[0172]

[0173]

[0174] In Table 3, N / A indicates that it is not applicable.

[0175] 4) Maximum power reduction (MPR)

[0176] Due to the different locations of resource blocks (RBs) for bandwidth allocation in high-order modulation and transmission, the maximum output power that can be reduced by the terminal device varies. Table 3 shows the MPR definition when the power class (PC) is 3. The main reasons for power back-off in the outer RB allocation area and the edge RB allocation area are ACLR and SEM.

[0178]

[0179] As can be understood, in Table 4, the superscript of the MPR value indicates the annotation index to which the MPR value applies. "Pi / 2BPSK w Pi / 2BPSK DMRS" indicates that Pi / 2BPSK is used as the demodulation reference signal (DMRS) sequence.

[0180] The protocol calculates the range corresponding to the RB start position RBStart (or RB_start) based on the number of RBs L_CRB allocated to the current terminal device and the total number of RBs N_RB within the channel bandwidth, defining the range to which the inner RB allocation area belongs. The edge RB allocation area is the area of ​​the leftmost or rightmost 1 or 2 RBs. The remaining area is the inner RB allocation area, and the area division is as follows: Figure 4 As shown. The internal RB allocation region is mainly limited by in-band metrics, such as EVM and in-band emission (IBE). The internal and edge RB allocation regions are mainly limited by out-of-band metrics, such as ACLR and SEM. Among them, the edge RB allocation region, due to its proximity to the edge and high power spectral density, often exhibits greater power backoff.

[0181] One of the factors affecting MPR is the RB allocation area, according to Figure 4 It can be clearly seen that it is mainly divided into three regions: the edge RB allocation region, the outer RB allocation region, and the inner RB allocation region. The inner RB allocation region is... Figure 4 The area enclosed by bold lines represents the subcarriers. Taking a channel bandwidth of 100MHz as an example, with a subcarrier spacing of 30kHz, 100MHz can contain N_RB = 273 RBs. The following explanation uses the example where RBStart's value ranges from 0 to 272, and L_CRB's value ranges from 1 to 273. However, besides the above ranges, RBStart and / or L_CRB can also have other ranges. For example, RBStart's value range could also be 1 to 273.

[0182] If the number of RBs allocated, L_CRB (or the length of RBs, RB_length) is less than or equal to 2, and the starting position of RBs, RBStart, is located at the upper or lower edge of the channel bandwidth, then it is an edge RB allocation area.

[0183] The starting position RBStart and the number of allocated RBs L_CRB in the internal RB allocation region satisfy the following conditions:

[0184] RBStart,Low≤RBStart≤RBStart,High;

[0185] L_CRB≤ceil(N_RB / 2).

[0186] Where RBStart,Low = max(1, floor(L_CRB / 2)) represents the minimum value of RBStart in the internal RB allocation area, and RBStart,High = N_RB – RBStart,Low – L_CRB represents the maximum value of RBStart in the internal RB allocation area. N_RB is the maximum number of RBs within the channel bandwidth of the terminal device (i.e., the total number of RBs). floor() represents rounding down, and ceil() represents rounding up. For example, floor(L_CRB / 2) is the largest integer less than or equal to L_CRB / 2, and ceil(N_RB / 2) is the smallest integer greater than or equal to N_RB / 2.

[0187] If it does not belong to either the internal RB allocation region or the edge RB allocation region, then it is an external RB allocation region.

[0188] Generally, the definition of MPR follows these basic rules: the MPR of a lower-order modulation scheme is less than or equal to the MPR of a higher-order modulation scheme; the MPR of the inner RB allocation region is less than or equal to the MPR of the outer RB allocation region; and the MPR of the outer RB allocation region is less than or equal to the MPR of the edge RB allocation region.

[0189] In the following text, the internal RB allocation area can be referred to as the internal resource area, the external RB allocation area as the external resource area, and the edge RB allocation area as the edge resource area.

[0190] 5) Memory effect

[0191] When the measurement of amplitude distortion, phase distortion, or intermodulation distortion of a power amplifier no longer solely depends on changes in the signal input power, but is also affected by changes in the envelope frequency of the input signal, especially when the upper and lower sidebands of the intermodulation distortion signal become asymmetrical, the study of the memory effect in the amplifier's nonlinear characteristics becomes particularly important. The memory effect refers to the influence of a device's current time-time characteristics on its previous time-time state, as if the device possesses memory; hence, this characteristic is called the memory effect. Significant memory effects occur when broadband OFDM signals pass through a power amplifier (PA), primarily manifested as asymmetry between the ACLR (Advanced Channel Ratio) on the left and right sides of the channel bandwidth, i.e., asymmetry in the power of adjacent channels. Specifically, the ACLR on the left side of the channel bandwidth is the ratio of the average power of the channel bandwidth to the average power of the adjacent channels to the left of the channel bandwidth. The ACLR on the right side of the channel bandwidth is the ratio of the average power of the channel bandwidth to the average power of the adjacent channels to the right of the channel bandwidth. Channel bandwidth can refer to all available resources within a carrier wave.

[0192] In this application, the left side can represent a lower frequency, and the right side can represent a higher frequency. Accordingly, the types of memory effects are divided into left type and right type.

[0193] In this application, "left" represents the channel bandwidth, where the ACLR of the channel adjacent to the left is higher than that of the channel adjacent to the right; or, in other words, "left" represents the channel bandwidth, where the power of the channel adjacent to the left is lower than that of the channel adjacent to the right. Figure 5 The diagram shows the power distribution of a PA with left memory effect in the allocated channel bandwidth, the left adjacent channel, and the right adjacent channel. It can be seen that the power of the left adjacent channel is lower than that of the right adjacent channel.

[0194] The right side indicates that the ACLR of the channel adjacent to the right of the channel bandwidth is higher than that of the channel adjacent to the left of the channel bandwidth; in other words, the right side indicates that the power of the channel adjacent to the right of the channel bandwidth is lower than that of the channel adjacent to the left of the channel. For example... Figure 6 The diagram shows the power distribution of a PA with right memory effect in the allocated channel bandwidth, the left adjacent channel, and the right adjacent channel. It can be seen that the power of the right adjacent channel is lower than that of the left adjacent channel.

[0195] It is understood that the meanings of "left" and "right" in this application can be interchanged. For example, "left" means that the ACLR of the channel adjacent to the right of the channel bandwidth is higher than that of the channel adjacent to the left, or that the power of the channel adjacent to the right of the channel bandwidth is lower than that of the channel adjacent to the left. Similarly, "right" means that the ACLR of the channel adjacent to the left of the channel bandwidth is higher than that of the channel adjacent to the left, or that the power of the channel adjacent to the right of the channel bandwidth is lower than that of the channel adjacent to the left.

[0196] Among them, the memory effect is mainly related to factors such as the manufacturing process of transistor devices, the self-heating of active power devices, the frequency bandwidth and bias of the input signal envelope, and the design quality of the matching network, and is a fundamental characteristic of a power amplifier (PA).

[0197] As can be seen, due to the memory effect of the PA (Power Amplifier), the power of the adjacent channels on the left and right is asymmetrical. This results in different maximum transmit powers available to the terminal device in the left and right edge regions within the channel bandwidth, or different PA power consumption even when the maximum transmit bandwidth is the same in the left and right edge regions. For example, keeping the PA power consumption constant, the maximum transmit power available to the terminal device within the channel bandwidth is lower on the edge of the adjacent channel with a smaller ACLR (Advanced Channel Limiting Ratio), and higher on the edge of the adjacent channel with a larger ACLR. Due to the memory effect, in order to suppress the power of the left and right adjacent channels to the same level, the maximum transmit power within the band on the left and right sides of the channel bandwidth will be different. In other words, when the network device schedules the terminal to transmit within the channel bandwidth, the spurious power in the adjacent channel with the scheduling resource closer to the side with the lower ACLR is greater than the spurious power in the adjacent channel with the scheduling resource closer to the side with the higher ACLR.

[0198] Currently, during the uplink transmission of terminal devices, network equipment does not determine scheduling resources based on the type of memory effect of the terminal. If the network equipment schedules the terminal to transmit near a channel bandwidth position adjacent to a channel with a lower ACLR, the terminal device will use a larger maximum power backoff value due to the higher spurious power of the adjacent channel on this side, resulting in a lower maximum transmit power. Conversely, when the network equipment schedules the terminal to transmit near a channel bandwidth position adjacent to a channel with a higher ACLR, the spurious power of the adjacent channel on this side is lower, allowing the terminal device to use a smaller maximum power backoff value, resulting in a higher maximum transmit power. Therefore, compared to scheduling the terminal to transmit near a channel bandwidth position adjacent to a channel with a lower ACLR, the network equipment schedules the terminal to transmit near a channel bandwidth position adjacent to a channel with a lower ACLR, resulting in a lower maximum transmit power.

[0199] Therefore, how to rationally allocate resources to improve the maximum transmission power of terminal equipment is a technical problem that urgently needs to be solved.

[0200] To address the aforementioned technical problems, embodiments of this application provide a communication method. In this method, a terminal device can indicate or provide a memory effect type to a network device. Correspondingly, the network device performs resource scheduling based on the terminal device's memory type, enabling the terminal device to transmit at a position on one side of the channel bandwidth supporting a larger maximum transmit power, thereby increasing the maximum transmit power. It is understood that increasing the maximum transmit power can increase the transmit power of the terminal device in certain situations.

[0201] The following will combine Figure 7 The process shown in S101-S103 describes the technical solution in this application.

[0202] Figure 7 This paper uses terminal devices and network devices as examples to illustrate the execution of actions. Actions performed by the terminal device can also be performed by a first communication device. This first communication device can be the terminal device itself, or a component applicable to the terminal device (such as a functional module or chip). Similarly, actions performed by the network device can be performed by a second communication device. This second communication device can be a network device (such as a base station), or a component applicable to the network device (such as a functional module or chip).

[0203] S101: The terminal device sends the first information. Correspondingly, the network device receives the first information.

[0204] In this application, the first information can be used to indicate the type of memory effect of the terminal device; in other words, the first information may include type information of the memory effect. The type of memory effect can be left or right. Wherein, a left-side memory effect type can indicate that the power of the left-side adjacent channel of the terminal device's channel bandwidth is lower than the power (or spurious power) of the right-side adjacent channel, such as... Figure 5 As shown; it can also mean that the ACLR of the left adjacent channel of the channel bandwidth of the terminal device is higher than the ACLR of the right adjacent channel. The following text uses this as an example to introduce the type of memory effect as left, but it is not excluded that the power of the right adjacent channel of the channel bandwidth is lower than the power of the left adjacent channel, and / or, it is not excluded that the ACLR of the right adjacent channel of the channel bandwidth is higher than the ACLR of the left adjacent channel, which is defined as the type of memory effect as right.

[0205] The type "right" indicates that the power of the right-hand adjacent channel of the terminal device's channel bandwidth is lower than the power of the left-hand adjacent channel, such as... Figure 6 As shown; it can also mean that the ACLR of the right adjacent channel of the channel bandwidth of the terminal device is higher than the ACLR of the left adjacent channel. The following text uses this as an example to introduce the type of memory effect as right, but it is not excluded that the power of the left adjacent channel of the channel bandwidth is lower than the power of the right adjacent channel, and / or, it is not excluded that the ACLR of the left adjacent channel of the channel bandwidth is higher than the ACLR of the right adjacent channel, which is defined as the type of memory effect as right.

[0206] In this application, the type of memory effect can be determined by measurement by the terminal device. As an example, the terminal device can measure the ACLR (denoted as ACLR_left) of the left adjacent channel and the ACLR (denoted as ACLR_right) of the right adjacent channel when transmitting signals within the channel bandwidth, and determine the type of memory effect based on the ACLR of the left and right adjacent channels. Specifically, if the ACLR of the left adjacent channel and the right adjacent channel satisfy the following condition, the type of memory effect of the terminal device is left: ACLR_left – ACLR_right > x dB, where x is a positive integer. Alternatively, if the ACLR of the left adjacent channel and the right adjacent channel satisfy the following condition, the type of memory effect of the terminal device is right: ACLR_right – ACLR_left > x dB, where x is a positive integer.

[0207] Furthermore, the memory type can also be configured in the factory settings of the terminal device, eliminating the need for measurement by the terminal device. It is understood that if multiple terminal devices have the same PA from the same batch, model, and / or manufacturer, the memory effect types of the multiple terminal devices can be the same or different.

[0208] In S101, the first information can be used to indicate that the power of the terminal device in the first adjacent channel is lower than that in the second adjacent channel. Alternatively, the first information can be used to indicate that the ACLR of the terminal device in the first adjacent channel is higher than that in the second adjacent channel, which can represent that the type of memory effect of the terminal device is left-handed. In other words, when the first information includes memory response type information, and the type information indicates a left-handed type, the first information is used to indicate that the power of the terminal device in the first adjacent channel is lower than that in the second adjacent channel.

[0209] In this context, the frequency of the first adjacent channel is lower than the frequency of the second adjacent channel. The frequency of the first adjacent channel is, for example, its center frequency or highest frequency, while the frequency of the second adjacent channel is, for example, its center frequency or lowest frequency. Alternatively, the first adjacent channel can be considered the left-hand adjacent channel of the channel bandwidth, and the second adjacent channel is the right-hand adjacent channel of the channel bandwidth. In this case, the type of memory effect indicated by the first information can be considered left-handed. Figure 5 As shown, the left adjacent channel can be considered as an example of the first adjacent channel, and the right adjacent channel can be considered as an example of the second adjacent channel. Figure 5 If the power of the first adjacent channel is lower than the power of the second adjacent channel, the type of memory effect can be left.

[0210] The power of a terminal device in the first adjacent channel can be understood as the spurious power or interference power detected by the terminal device in the first adjacent channel when transmitting signals within the channel bandwidth. The power of a terminal device in the second adjacent channel can also be understood as the spurious power or interference power detected by the terminal device in the second adjacent channel when transmitting signals within the channel bandwidth.

[0211] Additionally, the first information can be used to indicate that the power of the terminal device in the second adjacent channel is lower than that in the first adjacent channel. Alternatively, the first information can be used to indicate that the ACLR of the terminal device in the second adjacent channel is higher than that in the first adjacent channel. In this case, it can represent that the type of memory effect of the terminal device is right-handed. Alternatively, when the first information includes memory response type information, and the type information indicates a right-handed type, the first information is used to indicate that the power of the terminal device in the second adjacent channel is lower than that in the first adjacent channel. Figure 6 As shown, the left adjacent channel can be considered as an example of the first adjacent channel, and the right adjacent channel can be considered as an example of the second adjacent channel. Figure 6 If the power of the first adjacent channel is higher than the power of the second adjacent channel, the type of memory effect can be right.

[0212] Understandably, the first piece of information can occupy 1 bit. When this bit takes the first value, it represents a left-handed type of memory effect in the terminal device; when it takes the second value, it represents a right-handed type. The first and second values ​​are different. For example, the first value can be 0 and the second value can be 1; or the first value can be 1 and the second value can be 0.

[0213] S102: The network device determines the transmission resources of the terminal device based on the first information.

[0214] The transmission resources of a terminal device can be understood as the transmission bandwidth of the terminal device, which represents the transmission resources available to the terminal device configured by the network device.

[0215] It is understandable that the transmission resources of the terminal device can be at the RB granularity. In S102, the network device can determine the starting position and / or the number of RBs allocated to the terminal device based on the first information. In addition, the transmission resources of the terminal device can also be at the bandwidth granularity, etc., without specific limitations.

[0216] In S102, the network device can determine the terminal's transmission resources based on the first information and the terminal's channel bandwidth. The terminal's channel bandwidth can be configured by the network device within its bandwidth range. The network device's bandwidth refers to its total bandwidth within an operator's network.

[0217] For example, a network device may be configured with two component carriers (CCs), denoted as CC#1 and CC#2. The bandwidths of CC#1 and CC#2 are 100 MHz and 60 MHz respectively, meaning the network device's bandwidth is 160 MHz. A terminal can be configured with either CC#1 or CC#2. Taking a terminal device configured with CC#1 as an example, the terminal device's channel bandwidth is the bandwidth of CC#1, which is 100 MHz.

[0218] In one possible embodiment, if the first information indicates that the terminal device is of the left type, meaning the power of the terminal device's first adjacent channel is lower than the power of the second adjacent channel, the network device can preferentially allocate channel bandwidth or bandwidth closer to the left edge of the network device's bandwidth as transmission bandwidth to the terminal device. Figure 8A For example, with a channel bandwidth of 100MHz and a terminal device transmission bandwidth of 50MHz, when the terminal device's memory effect type is left, the network device can allocate 50MHz to the left of the center frequency of the channel bandwidth as the terminal device's transmission resource.

[0219] In addition, network devices can determine the terminal's transmission resources based on the first information and the network device's bandwidth.

[0220] by Figure 8B For example, if the bandwidth of the network device is 160MHz and the bandwidth of the terminal device is 100MHz, and if the first information indicates that the type of the terminal device is left, then in Example 1, the network device can allocate 100MHz of the center frequency of the network device's bandwidth to the left as the transmission resource of the terminal device.

[0221] Similarly, if the first information indicates that the terminal device type is right, meaning the power of the terminal device's second adjacent channel is lower than the power of the first adjacent channel, the network device can prioritize allocating bandwidth closer to the right edge of the channel bandwidth to the terminal device as transmission bandwidth. Figure 8A For example, network devices can allocate 50MHz to the right of the center frequency of the channel bandwidth as transmission resources for terminal devices.

[0222] And with Figure 8B For example, if the bandwidth of the network device is 160MHz and the bandwidth of the terminal device is 100MHz, and if the first information indicates that the type of the terminal device is right, then in Example 2, the network device can allocate 100MHz of the center frequency of the network device's bandwidth as the transmission resource of the terminal device.

[0223] In another possible embodiment, the network device can determine the transmission resources of the terminal device based on at least one of an external resource region, an internal resource region, or an edge resource region, and the first information. The external resource region (i.e., the external RB allocation region), the internal resource region (i.e., the internal RB allocation region), or the edge resource region (i.e., the edge RB allocation region) can be found in [reference needed]. Figure 4 And for Figure 4 Explanation.

[0224] In this application, the external resource area may include an external left resource area and an external right resource area. That is, the network device can determine the transmission resources of the terminal device based on at least one of the external left resource area, the external right resource area, the internal resource area, or the edge resource area, as well as the first information.

[0225] It is understood that at least one of the external resource area, external left resource area, external right resource area, internal resource area, or edge resource area can be determined based on the channel bandwidth or the bandwidth of the network device.

[0226] Optionally, when the bandwidth of the network device is greater than the channel bandwidth of the terminal, the network device can determine at least one of the following: an external resource area, an external left resource area, an external right resource area, an internal resource area, or an edge resource area, based on the bandwidth of the network device, to increase the maximum transmit power. For example, an RB in the external resource area based on the channel bandwidth may belong to the internal resource area when the aforementioned area is determined based on the bandwidth of the network device. Therefore, when the aforementioned area is determined according to the bandwidth of the network device, the terminal can use a higher maximum transmit power in that RB.

[0227] like Figure 4 The external resource area, internal resource area, and edge resource area shown can be determined based on the terminal's channel bandwidth or the network device's bandwidth. For example, the network device's bandwidth is 160MHz, and the channel bandwidth is 100MHz. It can be understood that, taking a subcarrier spacing of 30kHz as an example, if the bandwidth is determined based on the network device... Figure 4 The external resource region, internal resource region, and edge resource region shown indicate that the total number of resource blocks (RBs) N_RB = 435. Taking a subcarrier spacing of 30kHz as an example, if the channel bandwidth of the terminal is determined as follows... Figure 4 Given the external resource region, internal resource region, and peripheral resource region shown, the total number of RBs N_RB = 273.

[0228] The outer right-side resource region can also be called the outer right-side RB allocation region. If the outer right-side resource region is determined based on the channel bandwidth, the number of RBs to the right of the center frequency of the channel bandwidth in this region is greater than the number of RBs to the left, that is, the number of RBs with frequencies higher than the center frequency of the channel bandwidth is greater than the number of RBs with frequencies lower than the center frequency of the channel bandwidth.

[0229] like Figure 9 As shown, the black area represents the outer right resource region, and the sum of the white and black areas represents the complete channel bandwidth. Additionally, the outer left resource region can also be called the outer left RB allocation region. In this region, the number of RBs to the left of the center frequency of the channel bandwidth is greater than the number of RBs to the right. It can also be understood as the outer left resource region excluding the outer right resource region.

[0230] like Figure 4 As shown, the dashed lines to the left and right represent the outer left RB allocation area and the outer right RB allocation area, respectively.

[0231] As an example, the number of RBs with frequencies higher than the center frequency of the channel bandwidth is greater than the number of RBs with frequencies lower than the center frequency of the channel bandwidth, which can be described as:

[0232] RBStart+L_CRB–N_RB / 2>N_RB / 2–RBStart;

[0233] Rearranging the terms, we get:

[0234] 2RBStart + L_CRB > N_RB; (Formula 1)

[0235] RBStart indicates the starting position of the first transmission resource block in the transmission resource, L_CRB indicates the total number of transmission resource blocks in the transmission resource, and N_RB indicates the total number of transmission resource blocks within the channel bandwidth.

[0236] In addition, if the external right-side resource area is determined based on the bandwidth of the network device, the number of RBs to the right of the center frequency of the network device's bandwidth in this area is greater than the number of RBs to the left. That is, the number of RBs with frequencies higher than the center frequency of the network device's bandwidth is greater than the number of RBs with frequencies lower than the center frequency of the network device's bandwidth.

[0237] As an example, the external right-side resource area is determined based on the bandwidth of the network device. The external right-side resource area still satisfies Formula 1, where N_RB in Formula 1 represents the total number of transmission resource blocks within the bandwidth of the network device.

[0238] As an example, when determining the transmission resources of a terminal device based on at least one of an external resource area, an internal resource area, or an edge resource area, and the first information, the network device can determine the transmission resources from at least one of the external resource area, internal resource area, or edge resource area according to the type of memory effect of the terminal device indicated by the first information. That is, the network device can determine the transmission resources of the terminal device from at least one of the external left resource area, external right resource area, internal resource area, or edge resource area according to the type of memory effect of the terminal device indicated by the first information. When determining the transmission resources of the terminal, the network device can also refer to information such as the amount of data the terminal device needs to send, the location or width of other transmission resources already allocated within the bandwidth.

[0239] Taking the memory effect of the terminal device as an example, after determining the transmission resources of the terminal device from the external resource area, the network device can preferentially determine the transmission resources of the terminal device from the external right-hand resource area. For example, the network device can... Figure 4 The outer right RB allocation area shown determines the RB start position RBStart and the number of RBs allocated L_CRB.

[0240] Figure 8A This can be taken as an example of this embodiment. Taking a subcarrier spacing of 30kHz as an example, the network device can... Figure 4 The external left-side RB allocation region shown is designated as a transmission resource for terminal devices, where RBStart = 0 and L_CRB = 136. This transmission resource can be allocated to terminal devices with a left-side memory effect type. This transmission resource can be understood as... Figure 8A The bandwidth shown is 136 RBs within the 50MHz range to the left of the center frequency. This bandwidth can be the channel bandwidth. Alternatively, network devices can... Figure 4 The external right-side RB allocation area shown is designated as a transmission resource for terminal devices, with RBStart = 136 and L_CRB = 137. This transmission resource can be allocated to terminal devices with a right-side memory effect type. This transmission resource can be understood as... Figure 8A The bandwidth shown includes 136 RBs in the 50MHz range to the right of the center frequency and the RBs containing the center frequency of the bandwidth.

[0241] Additionally, network devices can also determine RBStart=0 and L_CRB=137 as transmission resources for terminal devices, which can be allocated to terminal devices with a left-hand memory effect type. This transmission resource can be understood as... Figure 8AThe bandwidth shown includes 136 RBs in the 50MHz range to the left of the center frequency and the RBs containing the center frequency of the bandwidth. Furthermore, network devices can determine RBStart=137 and L_CRB=136 from the external right-hand RB allocation area as transmission resources for terminal devices, which can be allocated to terminal devices with a right-hand memory effect type. This transmission resource can be understood as... Figure 8A The bandwidth shown has 136 RBs in the 50MHz range to the right of the center frequency.

[0242] Similarly, Figure 8B This can also be considered as an example of this embodiment. For instance, with a subcarrier spacing of 30kHz, the network device has a bandwidth of 160MHz, which includes 435 RBs. The network device can... Figure 4 The external left-hand RB allocation area shown identifies a transmission resource of L_CRB=273, which can be allocated to terminal devices with a memory effect type of left. Network devices can also... Figure 4 The external right-side RB allocation area shown is designated as L_CRB=273 as the transmission resource for the terminal device, which can be allocated to the terminal device with the memory effect type right.

[0243] In addition, network devices can also be obtained from Figure 4 The transmission resource L_CRB=273 is determined in the external left RB allocation area shown. Network devices can also... Figure 4 The transmission resource L_CRB=273 is determined in the external right-side RB allocation area shown as the transmission resource for the terminal device with a memory effect type of left.

[0244] It is understood that if a network device allocates transmission resources to a terminal based on the first information and the network device's bandwidth, and these transmission resources exceed the terminal's channel bandwidth, then transmission can be performed on the transmission resources allocated by the network device using carrier aggregation (CA). The transmission method of carrier aggregation is not limited to the scope of this application.

[0245] For example, Figure 8B The 160MHz shown represents the bandwidth of the network device, with the 100MHz on the left representing the terminal's channel bandwidth. If the network device allocates the right-hand 100MHz of transmission resources to the terminal, as shown in Example 2, the terminal can perform CA transmission within this 100MHz. Specifically, this 100MHz includes 40MHz of CC#1 and 60MHz of CC#2, therefore the terminal performs CA transmission on both CC#1 and CC#2.

[0246] S103: The network device sends the first message. Correspondingly, the terminal device receives the scheduling information. The terminal device can determine the transmission resources based on the scheduling information.

[0247] Scheduling information, for example, is carried in DCI.

[0248] Based on S101 to S103 above, the network device can allocate transmission resources to the terminal device according to the type of memory effect reported by the terminal device, and schedule the terminal device to transmit at one side of the channel bandwidth that supports a larger maximum transmit power, so as to improve the maximum transmit power.

[0249] After simulation and real signal testing, if the memory effect of the terminal device is right, or if the first information indicates that the type of memory effect is right, or if the first information is used to indicate that the power of the terminal device in the second adjacent channel is lower than the power of the terminal device in the first adjacent channel, or if the first information is used to indicate that the ACLR of the terminal device in the second adjacent channel is higher than the ACLR of the terminal device in the first adjacent channel, the network device allocates RBs to the terminal device from the external right RB allocation area, which can effectively reduce the power of the terminal device in the first adjacent channel. Here, the first adjacent channel corresponds to the adjacent channel with higher power, so the power backoff value used to suppress the power of the adjacent channel can be reduced, which is equivalent to increasing the maximum transmit power of the terminal device.

[0250] Similarly, if the memory effect of the terminal device is left, or if the first information indicates that the type of memory effect is left, or if the first information is used to indicate that the power of the terminal device in the first adjacent channel is lower than the power of the terminal device in the second adjacent channel, or if the first information is used to indicate that the ACLR of the terminal device in the second adjacent channel is higher than the ACLR of the terminal device in the first adjacent channel, the network device allocates RBs to the terminal device from the external left RB allocation area, which can effectively reduce the power of the terminal device in the second adjacent channel. Here, the second adjacent channel corresponds to the adjacent channel with higher power, so the power backoff value used to suppress the power of the adjacent channel can be reduced, which is equivalent to increasing the maximum transmit power of the terminal device.

[0251] In one possible embodiment, the terminal device may also send second information. Correspondingly, the network device may receive the second information.

[0252] The second information can be used to indicate the frequency band corresponding to the first information. This frequency band can be understood as the frequency band to which the first information applies. That is, when the terminal device sends the first and second information to the network device, it indicates that the type of memory effect of the terminal device under the frequency band indicated by the second information is the same as the type of memory effect indicated by the first information. Accordingly, the network device can determine whether to allocate transmission resources for the terminal device within the channel bandwidth based on the first information, according to the channel bandwidth and the frequency band corresponding to the first information. It can be understood that if the frequency band corresponding to the first information matches the frequency band of the channel bandwidth, the terminal device can determine its transmission resources within the channel bandwidth based on the first information. Specifically, when the center frequency and / or boundary frequency of the channel bandwidth are located within the frequency band corresponding to the first information, the frequency band corresponding to the first information matches the frequency band of the channel bandwidth. That is, the terminal device can operate in different frequency bands, and the first information can be used to indicate the type of memory effect when the terminal device operates in some or all of these frequency bands. The type of memory effect can be the same or different when the terminal device operates in different frequency bands. The terminal device can indicate the type of memory effect under any one or more frequency bands using the first and second information.

[0253] Similarly, network devices can determine whether to allocate transmission resources to terminal devices within the bandwidth of the network device based on the frequency band corresponding to the first information.

[0254] It is understandable that if the network device receives second information from the terminal device, it can determine the transmission resources based on the first and second information when executing S103. The network device determining the transmission resources based on the first and third information can be understood as follows: after determining that the frequency band corresponding to the first information matches the channel bandwidth based on the second information, the network device determines the transmission resources of the terminal device based on the first information and the channel bandwidth; or, after determining that the frequency band corresponding to the first information matches the network device's bandwidth based on the second information, the network device determines the transmission resources of the terminal device based on the first information and the network device's bandwidth. The method of determining the transmission resources of the terminal device based on the first information can be found in the description of S103, and will not be repeated here.

[0255] As an example, the second information can be used to indicate that the first information corresponds to all frequency bands, or in other words, the second information is used to indicate that the first information is a capability or configuration at the terminal device level. For scenarios where the terminal device is applicable to all frequency bands, any channel bandwidth configured by the network device for the terminal device or any bandwidth of any network device can be applied to the first information; that is, in S102, the network device can determine the transmission resources of the terminal device based on the first information.

[0256] In this example, the second information may include an identifier representing the terminal device level.

[0257] As another example, the second information can be used to indicate that the first information corresponds to one or more band combinations, or in other words, the second information is used to indicate that the first information is a capability or configuration at the band combination level. For scenarios where the terminal device is applicable to one or more band combinations, when the frequency (such as the center frequency or boundary frequency) of the channel bandwidth configured by the network device for the terminal device belongs to that band combination, that is, in S102 the network device can determine the transmission resources of the terminal device based on the first information. Alternatively, when the frequency of the network device's bandwidth belongs to that band combination, that is, in S102 the network device can determine the transmission resources of the terminal device based on the first information.

[0258] In this example, the second information may include an identifier or index representing one or more frequency band combinations corresponding to the first information.

[0259] As another example, the second information can be used to indicate that the first information corresponds to one or more frequency bands, or in other words, the second information is used to indicate that the first information is a frequency band-level capability or configuration. For scenarios where the terminal device is applicable to one or more frequency bands, when the frequency of the channel bandwidth configured by the network device for the terminal device belongs to that frequency band, that is, in S102 the network device can determine the transmission resources of the terminal device based on the first information. Alternatively, when the frequency of the network device's bandwidth belongs to that frequency band, that is, in S102 the network device can determine the transmission resources of the terminal device based on the first information.

[0260] In this example, the second information may contain an identifier or index representing one or more frequency bands corresponding to the first information.

[0261] In one possible embodiment, the terminal device may also send third information. Correspondingly, the network device may receive the third information. In S103, the network device may determine transmission resources based on the first information and the third information.

[0262] The third piece of information can be used to indicate the power level corresponding to the first piece of information. The power level is used to indicate the maximum transmit power of the terminal device. For example, power level 1 corresponds to a maximum transmit power of 31 dBm, power level 1.5 corresponds to a maximum transmit power of 29 dBm, power level 2 corresponds to a maximum transmit power of 26 dBm, and power level 3 corresponds to a maximum transmit power of 23 dBm.

[0263] The power level corresponding to the first information can be understood as the power level to which the first information applies. That is, when a terminal device sends the first and third information to a network device, it indicates that the type of memory effect of the terminal device at the power level indicated by the third information is the same as the type of memory effect indicated by the first information. Accordingly, the network device can determine whether to allocate transmission resources to the terminal device based on the first information, according to the power level of the terminal device and the power level corresponding to the first information. It can be understood that if the power level corresponding to the first information is the same as the power level of the terminal device, or if the power level corresponding to the first information includes the power level of the terminal device, then the transmission resources of the terminal device can be determined based on the first information. In other words, the terminal device can operate at different power levels, and the first information can be used to indicate the type of memory effect when the terminal device operates at some or all of these power levels.

[0264] It is understandable that if third information is received from the terminal device, the network device, when executing S103, can determine the transmission resources based on the first information and the third information. Determining the transmission resources based on the first and third information can be understood as follows: after the network device determines, based on the third information, that the power level corresponding to the first information is the same as or includes the power level of the terminal device, it determines the transmission resources of the terminal device based on the first information. The method for determining the transmission resources of the terminal device based on the first information can be found in the description of S103, and will not be repeated here.

[0265] As an example, the power level corresponding to the first piece of information can be power level 1, power level 1.5, power level 2, or power level 3, etc., without specific limitations.

[0266] It can also be understood that if the network device receives first information, second information, and third information from the terminal device, then during the execution of S103, it can determine the transmission resources based on the first information, second information, and third information. Specifically, the network device can determine the transmission resources of the terminal device based on the first information after determining that the frequency band corresponding to the first information matches the frequency band of the channel bandwidth (or the bandwidth of the network device) based on the second information, and after determining that the power level corresponding to the first information is the same as or includes the power level of the terminal device based on the third information.

[0267] In one possible embodiment, one or more of the first, second, and third information can be carried in the terminal device capability information. That is, the terminal device can send one or more of the first, second, and third information through terminal device capability reporting.

[0268] Optionally, prior to S101, the network device may send a memory effect type request to the terminal device to request first information. As an example, the memory effect type request is a capability query request, and correspondingly, the terminal device may include the first information in its capability information.

[0269] Optionally, the terminal device capability information may also include switch information to indicate whether the terminal device has enabled the memory effect type indication. If the terminal device has enabled the memory effect type indication, the terminal device capability information may include first information, and optionally, second and / or third information. The switch information may also have other names; this application does not specifically require them.

[0270] Understandably, the switch information can occupy 1 bit in the terminal device capability information. When this bit has a first value, it indicates that the terminal device's memory effect type is enabled, or in other words, that the terminal device's memory effect type is being reported. When this bit has a second value, it indicates that the terminal device's memory effect type is not enabled, or in other words, that the terminal device's memory effect type is not being reported. The first and second values ​​are different. For example, the first value can be 0 and the second value can be 1; or the first value can be 1 and the second value can be 0.

[0271] In one possible embodiment, the terminal device can determine maximum power backoff information based on the first information. In this application, since the network device can determine the allocation of transmission resources to the terminal device based on the first information, the terminal device can correspondingly adopt a higher maximum transmit power to increase the transmit power. For example, after determining the MPR (Maximum Transmit Ratio) with reference to the table shown in Table 4, the terminal device can reduce the MPR value to achieve a higher transmit power. For example, for an external RB (Radio Repository Block) allocation area, a reduction value x can be set based on the MPR values ​​shown in Table 4. After querying the corresponding MPR value according to Table 4, x dB is reduced from that MPR value as the maximum power backoff value. Alternatively, when the transmission resources of the terminal device are determined based on the first information, the maximum power backoff information of the terminal device can be, for example, the maximum power backoff value determined based on the MPR value and x.

[0272] For example, according to Table 4, when the coding scheme is 16QAM, the original MPR value of the external resource area is 2dB. Taking x=1 as an example, the terminal device can use (MPR-x)dB as the maximum power backoff value to determine the maximum transmit power. Taking power level 2, i.e., the maximum transmit power of the terminal device is 26dBm, as an example, the transmit power of the terminal device can be 26-(MPR-x). Taking x=1 as an example, the transmit power of the terminal device can be 25dBm.

[0273] As an example, the value of x and the method for determining the maximum backoff power information can be added as a new note to Table 4 of the protocol. For example, the following note can be added: For external RB allocation areas, if at least one of the following is satisfied: the terminal device enables the memory effect type indication, the terminal device sends first information, or the network device determines the terminal device's transmission resources based on the first information, then the terminal device determines the maximum transmit power based on x, or the terminal device determines the maximum transmit power based on MPR and x, or the terminal device determines the maximum transmit power based on (MPR-x). Where MPR can be greater than or equal to 1, and x is greater than 0.

[0274] Optionally, the maximum power backoff information can correspond to the channel bandwidth or the bandwidth of the network device. In other words, different channel bandwidths or network device bandwidths can correspond to different maximum power backoff information. For example, different channel bandwidths can correspond to different x values. When determining the terminal's transmission resources based on the first information and the channel bandwidth, the terminal can determine the maximum transmit power based on the maximum power backoff information corresponding to the channel bandwidth. Similarly, different network device bandwidths can correspond to different x values. When determining the terminal's transmission resources based on the first information and the network device's bandwidth, the terminal can determine the maximum transmit power when transmitting signals using that transmission resource based on the maximum power backoff information corresponding to the network device's bandwidth. For instance, annotations can be added to the MPR table shown in Table 4, containing the correspondence between x values ​​and channel bandwidths, and / or, the correspondence between x values ​​and network device bandwidths.

[0275] In one possible embodiment, the terminal device may determine the transmit power based on transmission resources and operator information of either the first adjacent channel (i.e., the left adjacent channel) or the second adjacent channel (i.e., the right adjacent channel). The operator information can be used to determine the operator network corresponding to the frequency band; for example, the operator information includes an operator identifier.

[0276] If the terminal device's transmission resources belong to the outer left-side resource area, the terminal device can determine the maximum transmit power of that transmission resource based on the operator information of the first adjacent channel. For example, if... Figure 10 As shown, the network device has a bandwidth of 160MHz, of which the higher frequency 100MHz is configured as the channel bandwidth for the terminal device, and the lower frequency 60MHz overlaps with the terminal device's first adjacent channel. If the terminal device's transmission resources (in Figure 10(Represented by the black area in the image) Located in the outer left resource area, and the terminal device determines that the operator of the first adjacent channel is the same as the operator of the channel bandwidth where the terminal device's transmission resource is located based on the operator information of the first adjacent channel, then the terminal device can reduce the MPR value after determining it with reference to the table shown in Table 4, in order to achieve greater transmit power. Since the first adjacent channel and the terminal device's channel bandwidth belong to the same operator, the spurious power of the terminal in the first adjacent channel falls within the base station's band. This spurious power is not limited by the ACLR and SEM of the terminal's channel bandwidth, but is limited by the ACLR and SEM of the base station's bandwidth. That is, the terminal does not need to suppress adjacent channel power according to the range of the terminal's channel bandwidth, but can suppress adjacent channel power according to the frequency range of the base station's bandwidth. Therefore, it can be understood that the adjacent channel spurious power of the base station caused by the terminal transmitting on this transmission resource is relatively small, so the terminal does not need to suppress transmit power excessively, and thus can increase the terminal's transmit power. For example, based on the MPR values ​​shown in Table 4, a reduction value y can be set for the MPR. After looking up the corresponding MPR value in Table 4, y dB can be reduced from this MPR value as the maximum power backoff value.

[0277] The first information can indicate that the power of the terminal device in the first adjacent channel is less than the power of the terminal device in the second adjacent channel. That is, it can require that the type of memory effect of the terminal device be left, or it can not require that the type of memory effect of the terminal device be left.

[0278] It is understandable that terminal devices can obtain operator information from messages sent by network devices. Taking the operator information of the first adjacent channel as an example, network devices can carry the correspondence between frequency bands and operator information in broadcast messages such as system information blocks (SIBs). Accordingly, terminal devices can obtain the correspondence between frequency bands and operator information by receiving broadcast messages, and further obtain the operator information of the first adjacent channel. Alternatively, network devices can carry the correspondence between frequency bands and operator information in terminal device-specific signaling. Similarly, terminal devices can obtain the correspondence between frequency bands and operator information through terminal device-specific signaling, and further obtain the operator information of the first adjacent channel. Furthermore, terminal devices can also obtain the correspondence between frequency bands and operator information through predefined or pre-configured methods.

[0279] Similarly, such as Figure 11 As shown, the base station has a bandwidth of 160MHz, of which the lower frequency 100MHz is configured as the channel bandwidth for the terminal equipment, and the higher frequency 60MHz overlaps with the terminal equipment's second adjacent channel. If the terminal equipment's transmission resources (in...) Figure 11(The area shown in black) belongs to the outer right-side resource area. The terminal device can determine the maximum transmit power in this transmission resource based on the operator information of the second adjacent channel. The first information can indicate that the terminal device's power in the second adjacent channel is less than its power in the first adjacent channel; that is, it can require the terminal device's memory effect type to be right-handed, or it can disregard the type of memory effect.

[0280] As an example, the value of y and the method for determining the maximum backoff power information can be added as a new annotation to Table 4 of the protocol. For example, add the following annotation: For the external left-side RB allocation area, if the channel bandwidth of the terminal device is adjacent to the channel bandwidth on the left side and belongs to the same operator network, then the terminal device determines the maximum transmit power based on y, or, the terminal device determines the maximum transmit power based on MPR and y, or, the terminal device determines the maximum transmit power based on (MPR-y). Here, MPR can be greater than or equal to 1, and y is greater than 0.

[0281] Similarly, the following note can be added: For the external right-side RB allocation area, if the channel bandwidth of the terminal device is adjacent to the channel bandwidth on the right side and the channel bandwidth belongs to the same operator network, then the terminal device determines the maximum transmit power according to y, or the terminal device determines the maximum transmit power according to MPR and y, or the terminal device determines the maximum transmit power according to (MPR-y).

[0282] Optionally, the maximum power backoff information can correspond to the channel bandwidth; in other words, the value of y is associated with the channel bandwidth. Different channel bandwidths can correspond to different maximum power backoff information. For example, different channel bandwidths can correspond to different y values. For instance, a note could be added to the MPR table shown in Table 4, containing the correspondence between y values ​​and channel bandwidths.

[0283] Optionally, the y-value corresponding to the outer left resource region and the y-value corresponding to the outer right resource region can be the same or different. If they are different, the y-value corresponding to the outer left resource region and the y-value corresponding to the outer right resource region can be represented as y1 and y2 respectively.

[0284] It is understandable that the scheme for determining the maximum transmission power of the terminal device based on y can be implemented in conjunction with the first information or independently of the first information. That is, regardless of whether the terminal device sends the first information, as long as the transmission resource of the terminal device belongs to the outer left resource area, the terminal device can determine the maximum transmission power of that transmission resource based on the operator information of the first adjacent channel, and / or, as long as the transmission resource of the terminal device belongs to the outer right resource area, the terminal device can determine the maximum transmission power of that transmission resource based on the operator information of the second adjacent channel.

[0285] In one possible embodiment, the terminal device can also reduce the power consumption when transmitting signals through transmission resources. For example, the terminal device can reduce the voltage without changing the transmission power, thereby reducing power consumption.

[0286] As an example, after the terminal device sends the first message to the network device and receives the scheduling information, the terminal device can transmit according to the scheduling information with lower power consumption. The power reduction of the terminal device can be denoted as p joules per bit (J / bit). The value of p can be added as a comment to Table 4 of the protocol or a table regarding the transmit power consumption of the terminal device. For example, the following comment can be added: For an external RB allocation area, if at least one of the following is satisfied: the terminal device enables the memory effect type, the terminal device sends the first message, or the network device determines the transmission resources of the terminal device based on the first message, then the terminal device determines the transmit power consumption based on p; for example, the terminal device reduces the transmit power consumption by p joules per bit.

[0287] Optionally, the power reduction value can correspond to the channel bandwidth or the bandwidth of the network device. In other words, different channel bandwidths or network device bandwidths can correspond to different power reduction values. For example, different channel bandwidths can correspond to different p values. When determining transmission resources based on the first information and the channel bandwidth, the terminal can determine the power consumption based on the power reduction value corresponding to that channel bandwidth. Similarly, different network device bandwidths can correspond to different p values. When determining transmission resources based on the first information and the network device bandwidth, the terminal can determine the power consumption when transmitting signals on that transmission resource based on the power reduction value corresponding to the network device bandwidth. For instance, annotations can be added to the MPR table shown in Table 4, which include the correspondence between y values ​​and channel bandwidth, and / or, the correspondence between y values ​​and network device bandwidth.

[0288] As another example, when the terminal device's transmission resources belong to either the outer left resource region or the outer right resource region, the terminal device can determine the transmission power consumption based on the operator information of the first adjacent channel (i.e., the left adjacent channel) or the second adjacent channel (i.e., the right adjacent channel). For example, the terminal device can... In this example, the power consumption reduction of the terminal device can be denoted as q joules per bit.

[0289] For example, if the terminal device's transmission resources belong to the outer left resource area, the terminal device can determine whether to reduce the power consumption of that transmission resource based on the operator information of the first adjacent channel. For instance, if the operator of the first adjacent channel is determined to be the same as the operator of the channel bandwidth where the terminal device's transmission resources are located, the terminal device can determine the transmission power consumption based on q. For example, the terminal device can reduce the transmission power consumption by q joules per bit to transmit with lower power consumption.

[0290] For example, if the terminal device's transmission resources belong to the external right-side resource area, the terminal device can determine whether to reduce power consumption on that transmission resource based on the operator information of the first adjacent channel. For instance, if the operator of the second adjacent channel is determined to be the same as the operator of the channel bandwidth where the terminal device's transmission resources are located, based on the operator information of the first adjacent channel, the terminal device can determine the transmission power consumption based on q. For example, the terminal device can reduce the transmission power consumption by q joules per bit to transmit using lower power.

[0291] In the above example, the value of q can be used as a comment and added to Table 4 of the protocol or a table about the transmit power consumption of the terminal device.

[0292] Optionally, the power reduction value can be associated with the channel bandwidth or the bandwidth of the network device. In other words, different channel bandwidths or network device bandwidths can correspond to different power reduction values. For example, different channel bandwidths can correspond to different p values. For instance, a note could be added to the MPR table shown in Table 3, which includes the correspondence between the y values ​​and the channel bandwidth or network device bandwidth.

[0293] Optionally, the q value corresponding to the outer left resource region and the q value corresponding to the outer right resource region can be the same or different. If they are different, the q value corresponding to the outer left resource region and the q value corresponding to the outer right resource region can be represented as q1 and q2, respectively.

[0294] In one possible embodiment, the terminal device may also send fourth information. This fourth information indicates the difference between the power of the terminal device in the first adjacent channel and the power of the terminal device in the second adjacent channel (referred to as the adjacent channel power difference), or, in other words, the fourth information indicates the adjacent channel power difference when the terminal device transmits signals within the channel bandwidth.

[0295] It can be understood that the power difference between adjacent channels can also be equivalently replaced by the difference between the ACLR of the first adjacent channel and the ACLR of the second adjacent channel (referred to as the ACLR difference between adjacent channels).

[0296] Correspondingly, the network device receives the fourth information and determines the scheduling priority of the terminal device based on the fourth information. The scheduling priority is positively correlated with the absolute value of the power difference (or the ACLR difference between adjacent channels). The scheduling priority is also positively correlated with the priority the network device places on scheduling the terminal device. That is, the larger the absolute value of the power difference between adjacent channels and / or the absolute value of the ACLR difference between adjacent channels, the higher the scheduling priority of the terminal device, meaning the network device can prioritize scheduling that terminal device. In other words, it can prioritize allocating transmission resources to the terminal device from the channel bandwidth or the network device's bandwidth. It can be understood that the larger the absolute value of the power difference between adjacent channels and / or the absolute value of the ACLR difference between adjacent channels, the greater the benefit of the increased transmit power resulting from allocating transmission resources to the terminal device using the method of this application.

[0297] As shown in Table 5, the larger the absolute value of the power difference between adjacent channels and the larger the ACLR difference between adjacent channels, the higher the scheduling priority of the corresponding terminal device.

[0298] Table 5

[0299]

[0300] It is understandable that the fourth piece of information can also indicate the difference level. For example, the difference level represents the level corresponding to the power difference between adjacent channels and / or the ACLR difference between adjacent channels. Similar differences can be combined into one difference level to reduce indication overhead.

[0301] As an example, when the power difference between adjacent channels is greater than a first threshold and / or the ACLR difference between adjacent channels is greater than a second threshold, the scheduling priority of the terminal device is higher than the priority corresponding to the first threshold. Taking Table 5 as an example, assuming the first threshold is 1, when the power difference between adjacent channels is greater than 1, the scheduling priority of the terminal device is higher than 1.

[0302] As another example, when the power difference between adjacent channels falls within a first power range, the scheduling priority of the terminal device is the scheduling priority corresponding to the first power range. Furthermore, when the power difference between adjacent channels falls within a second power range, the scheduling priority of the terminal device is the second scheduling priority corresponding to the second power range. Wherein, if the power in the first power range is greater than the power in the second power range, the second scheduling priority is higher than the first scheduling priority. For example, when the first power range is greater than 0 and less than or equal to 1, the scheduling priority corresponding to the first power range is 1; when the second power range is greater than 1 and less than or equal to 2, the scheduling priority corresponding to the second power range is 2.

[0303] Taking Table 5 as an example, if the network device determines that the difference level corresponding to terminal device #1 is I based on at least one of the adjacent channel power difference, adjacent channel ACLR difference, or difference level reported by terminal device #1 through the fourth information, and determines that the difference level corresponding to terminal device #1 is V based on at least one of the adjacent channel power difference, adjacent channel ACLR difference, or difference level reported by terminal device #2 through the fourth information, then within the same (or overlapping) channel bandwidth range, the network device can preferentially allocate transmission resources to terminal device #2. Specifically, the scheduling priority of terminal device #1 is 1, and the scheduling priority of terminal device #2 is 5, meaning that scheduling of terminal device #2 is prioritized. In other words, after allocating transmission resources to terminal device #2, the network device allocates transmission resources to terminal device #1.

[0304] It is understood that the examples of values ​​such as channel bandwidth and subcarrier spacing in the tables and other methods in this application are merely illustrative and should not be construed as limiting the scope of protection of this application to the illustrative values.

[0305] It is understood that, in order to achieve the functions in the above embodiments, the terminal device or network device includes hardware structures and / or software modules corresponding to perform each function.

Figure 7 The terminal device in the illustrated method embodiment has the following functions. Specifically, the transceiver unit 1220 can be used to transmit first information, which indicates that the power of the terminal device in a first adjacent channel is lower than the power of the terminal device in a second adjacent channel; or, the first information indicates that the power of the terminal device in the second adjacent channel is lower than the power of the terminal device in the first adjacent channel; wherein the frequency of the first adjacent channel is lower than the frequency of the second adjacent channel; the transceiver unit 1220 can also be used to receive scheduling information, which indicates the transmission resources of the terminal device, and the scheduling information is determined based on the first information.

[0309] In one possible implementation, the scheduling information is determined based on the first information, including: the transmission resources are determined based on the first information and the channel bandwidth.

[0310] In one possible implementation, the scheduling information is determined based on the first information, including: the transmission resources are determined based on the first information and the bandwidth of the network device.

[0312] In one possible implementation, the number of resource blocks in the outer right-side resource region that have a frequency higher than the center frequency of the channel bandwidth is greater than the number of resource blocks that have a frequency lower than the center frequency of the channel bandwidth. Additionally, in the outer left-side resource region, the number of resource blocks that have a frequency lower than the center frequency of the channel bandwidth is greater than the number of resource blocks that have a frequency higher than the center frequency of the channel bandwidth.

[0313] In one possible implementation, the transmission resource is determined based on the first information and the bandwidth of the network device, including: the transmission resource is determined based on at least one of an external left resource area, an external right resource area, an internal resource area, and an edge resource area, and the first information, wherein at least one of the external left resource area, the external right resource area, the internal resource area, and the edge resource area is determined based on the bandwidth of the network device.

[0314] In one possible implementation, the number of resource blocks in the outer right-side resource region that have a frequency higher than the center frequency of the network device's bandwidth is greater than the number of resource blocks that have a frequency lower than the center frequency of the network device's bandwidth. Conversely, the number of resource blocks in the outer left-side resource region that have a frequency lower than the center frequency of the network device's bandwidth is greater than the number of resource blocks that have a frequency higher than the center frequency of the network device's bandwidth.

[0315] In one possible implementation, if the terminal's transmission resources belong to the outer left-side resource area, the processing unit 1210 can determine the terminal's maximum power back-off information and / or power consumption reduction value for that transmission resource based on the operator information of the first adjacent channel.
