AI Technical Summary
When a broadband OFDM signal passes through a power amplifier, the asymmetry of spurious power in the left and right adjacent channels leads to an imbalance in the maximum transmit power of the terminal. Existing technologies have failed to effectively allocate resources to improve the maximum transmit power of the terminal.
By sending information indicating the memory effect type of the terminal device, transmission resources are rationally scheduled to avoid transmission on the channel bandwidth near the side with higher spurious power, thereby reducing the power backoff value and increasing the maximum transmit power of the terminal.
It enables flexible resource scheduling based on the memory effect type of terminal devices, thereby increasing the maximum transmit power of terminal devices, reducing power consumption, and optimizing spurious power suppression within the channel bandwidth.

A communication method and apparatus
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to the Chinese Patent Application No. 202411070461.6, filed on August 5, 2024, and entitled “A communication method and apparatus”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD
[0003] The present application relates to the field of mobile communication technology, and in particular to a communication method and apparatus. BACKGROUND
[0004] A power amplifier (PA) can amplify a low-power signal generated by a network device or a terminal device to a power level that can be transmitted over a long distance, and is a core device of a wireless communication device.
[0005] Due to factors such as the manufacturing process of transistor devices, self-heating of active power devices, input signal envelope frequency bandwidth and bias, and the design quality of matching networks, a wideband orthogonal frequency division multiplexing (OFDM) signal will produce significant memory effects when passing through a PA. The most important performance is that the adjacent channel leakage ratio (ACLR) on the left side of the channel bandwidth and the ACLR on the right side are asymmetric, that is, the left and right adjacent channel spurs are asymmetric. In order to suppress the left and right adjacent channel spurs to the same level, it will cause the maximum transmit power in the channel bandwidth to be different on the left and right sides. That is, when the network device schedules the terminal to transmit in the channel bandwidth, the spur in the adjacent channel when the scheduling resource is close to the side of the lower ACLR is greater than the spur in the adjacent channel when the scheduling resource is close to the side of the higher ACLR.
[0006] Currently, the network device does not determine the scheduling resource according to the type of the memory effect of the terminal in the uplink transmission process of scheduling the terminal device. If the network device schedules the terminal to transmit at a channel bandwidth position close to an adjacent channel with low ACLR, the terminal device will adopt a larger maximum power backoff value due to the larger spurious power of the adjacent channel on this side, and the maximum transmit power of the terminal is smaller. When the network device schedules the terminal to transmit at a channel bandwidth position close to an adjacent channel with high ACLR, the spurious power of the adjacent channel on this side is smaller, and the terminal device can adopt a smaller maximum power backoff value, and the maximum transmit power of the terminal is larger. Therefore, compared with scheduling the terminal to transmit at a channel bandwidth position close to an adjacent channel with high ACLR, scheduling the terminal to transmit at a channel bandwidth position close to an adjacent channel with low ACLR will cause the maximum transmit power of the terminal to decrease. Based on this, how to reasonably schedule resources to improve the maximum transmit power of the terminal is currently a technical problem to be solved. SUMMARY
[0007] The present application provides a communication method and device for reasonably scheduling resources to improve the maximum transmit power of the terminal.
[0008] In a first aspect, an embodiment of the present application provides a communication method, which can be executed by a first device. In the absence of special description, the "first device" in the present application can refer to the first device itself (for example, a terminal device), a component (for example, a functional module, a communication module, a processor, a circuit, a chip, or a chip system, etc.) in the first device, or a logic module or software capable of realizing all or part of the functions of the first device. Taking the terminal device as an example, the method comprises: the first device sends first information, which 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 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; wherein the frequency of the first adjacent channel is lower than the frequency of the second adjacent channel; the terminal device receives scheduling information, which is used to indicate the transmission resource of the terminal device, and the scheduling information is determined according to the first information.
[0009] In other words, the first information can be used to indicate the type of the memory effect of the terminal device.
[0010] Based on the implementation, the first information can be used to indicate the memory effect type of the terminal device, wherein the memory effect causes the terminal to have different spurious power in the left adjacent channel and the right adjacent channel. It can be understood that if it is required to suppress the spurious power of the two adjacent channels to the same level, the terminal transmission power needs to be suppressed according to the larger spurious power, which causes the terminal transmission power to be reduced. Based on the manner of the present application, the second communication device can reasonably determine the transmission resource of the terminal according to the first information (or according to the type of the memory effect of the terminal device indicated by the first information), avoid scheduling the terminal in the channel bandwidth of the adjacent channel close to the side where the terminal has larger spurious power, and reduce the spurious power. Therefore, the terminal does not need to excessively suppress the transmission power, and the maximum transmission power of the terminal can be increased.
[0011] In a possible implementation, the scheduling information is determined according to the first information, and the transmission resource is determined according to the first information and the channel bandwidth.
[0012] Based on the implementation, the second communication device can flexibly determine the transmission resource 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.
[0013] In a possible implementation, the scheduling information is determined according to the first information, and the transmission resource is determined according to the first information and the bandwidth of the network device.
[0014] Based on the implementation, the second communication device can flexibly determine the transmission resource of the terminal device according to the first information and the bandwidth of the network device.
[0015] In a possible implementation, the transmission resource is determined according to the first information and the channel bandwidth, and the transmission resource is determined according to 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, and 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 according to the channel bandwidth.
[0016] It can be understood that "left" in the present application represents low frequency, and "right" represents high frequency.
[0017] Based on the implementation, the second communication device can determine at least one of the outer left resource region, the outer right resource region, the inner resource region and the edge resource region according to the channel bandwidth of the terminal device, and determine the transmission resource of the terminal device according to the at least one region and the first information. For example, the second communication device can determine the transmission resource of the terminal device from at least one of the outer left resource region, the outer right resource region, the inner resource region and the edge resource region according to the first information. The outer left resource region, the outer right resource region, the inner resource region and the edge resource region all belong to the channel bandwidth.
[0018] In a possible implementation, the number of resource blocks with a frequency higher than the center frequency of the channel bandwidth in the outer right resource region is greater than the number of resource blocks with a frequency lower than the center frequency of the channel bandwidth. In addition, the number of resource blocks with a frequency lower than the center frequency of the channel bandwidth in the outer left resource region is greater than the number of resource blocks with a frequency higher than the center frequency of the channel bandwidth.
[0019] Through simulation and real signal test, if the memory effect of the terminal device is right, or in other words, if the first information indicates that the type of the memory effect is right, or in other words, 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 in other words, 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 the transmission resource for the terminal device from the outer right resource region, which can effectively reduce the power of the terminal device in the first adjacent channel, wherein the first adjacent channel is the adjacent channel corresponding to the higher power, and thus 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.
[0020] If the memory effect of the terminal device is left, or in other words, if the first information indicates that the type of the memory effect is left, or in other words, 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 in other words, 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 the transmission resource for the terminal device from the outer left resource region, which can effectively reduce the power of the terminal device in the second adjacent channel, wherein the second adjacent channel is the adjacent channel corresponding to the higher power, and thus 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.
[0021] In a possible implementation, the transmission resource is determined according to the first information and a bandwidth of the network device, including: the transmission resource is determined according to at least one of an outer left resource region, an outer right resource region, an inner resource region and an edge resource region and the first information, and the at least one of the outer left resource region, the outer right resource region, the inner resource region and the edge resource region is determined according to the bandwidth of the network device. The outer left resource region, the outer right resource region, the inner resource region and the edge resource region all belong to the bandwidth of the network device.
[0022] Based on the implementation, the second communication apparatus can determine at least one of an outer left resource region, an outer right resource region, an inner resource region and an edge resource region according to the bandwidth of the network device, and determine the transmission resource of the terminal device according to the at least one region and the first information. For example, the second communication apparatus can determine the transmission resource of the terminal device from the at least one of the outer left resource region, the outer right resource region, the inner resource region and the edge resource region according to the first information.
[0023] In a possible implementation, the outer right resource region contains more resource blocks with a frequency higher than a center frequency of the bandwidth of the network device than resource blocks with a frequency lower than the center frequency of the bandwidth of the network device. In addition, the outer left resource region contains more resource blocks with a frequency lower than the center frequency of the bandwidth of the network device than resource blocks with a frequency higher than the center frequency of the bandwidth of the network device.
[0024] Based on the implementation, the power backoff value for suppressing adjacent channel power can be reduced, which means that the maximum transmit power of the terminal device can be increased.
[0025] In a possible implementation, if the transmission resource of the terminal belongs to the outer left resource region, the first communication apparatus can further determine the maximum power backoff information and / or the power consumption reduction value of the terminal on the transmission resource according to the operator information of the first adjacent channel. If the transmission resource of the terminal belongs to the outer right resource region, the first communication apparatus can further determine the maximum power backoff information and / or the power consumption reduction value of the terminal on the transmission resource according to the operator information of the second adjacent channel.
[0026] Based on the implementation, the terminal device can determine the maximum power backoff information according to the operator information of the adjacent channel to increase the maximum transmit power. In addition, the terminal device can also determine the transmit power consumption according to the operator information of the adjacent channel to reduce the transmit power consumption.
[0027] In a possible implementation, the external left resource region and the external right resource region are located in an external resource region in the channel bandwidth or the bandwidth of the network device.
[0028] In a possible implementation, 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, and the first information comprises type information of a memory effect of a power amplifier of the terminal device, the type information indicating that the type of the memory effect is left. In other words, the first information can be used to indicate that the type of the memory effect is left.
[0029] In a possible implementation, 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, and the first information comprises type information of a memory effect of a power amplifier of the terminal device, the type information indicating that the type of the memory effect is right. In other words, the first information can be used to indicate that the type of the memory effect is right.
[0030] Optionally, when the power of the first adjacent channel is lower than the power of the terminal device in the second adjacent channel, the corresponding memory effect can also be of the type right, and when the power of the second adjacent channel is lower than the power of the terminal device in the first adjacent channel, the corresponding memory effect can be of the type left.
[0031] In a possible implementation, the first communication device can further send second information, and the second information is used to indicate a frequency band corresponding to the first information, the frequency band corresponding to the first information being all frequency bands, one or more combinations of frequency bands, or one or more frequency bands.
[0032] Based on the implementation, the first communication device can report the frequency band to which the memory type is applicable to the second communication device, so that the second communication device allocates transmission resources for the terminal device according to the first information in the corresponding frequency band. It can be understood that the terminal device can correspond to different types of memory effects in different frequency bands, so as to realize flexible scheduling of resources according to the types of memory effects of the terminal device in different frequency bands.
[0033] In a possible implementation, the first communication device can further send third information, and the third information is used to indicate a power level corresponding to the first information.
[0034] Based on the implementation, the first communication device can report the power level to which the memory type is applicable to the second communication device, so that the second communication device allocates transmission resources for the terminal device according to the first information under the corresponding power level. It can be understood that the terminal device can correspond to different types of memory effects in different power levels, so as to realize flexible scheduling of resources according to the types of memory effects of the terminal device in different power levels.
[0035] In a possible implementation, the first communication device can further determine, according to the first information, maximum power backoff information of the terminal device on the transmission resource.
[0036] Based on the implementation, the first communication device can determine the maximum power backoff information according to the first information. In other words, the first communication device can determine the maximum power backoff information according to the type of memory effect. When the terminal sends the first information, and / or when the second communication device allocates the transmission resource to the terminal device according to the first information, the power of the adjacent channel with higher power can be suppressed, and therefore the first communication device can use smaller maximum power backoff information when transmitting on the transmission resource, so as to improve the maximum transmission power. As an example, if the transmission resource of the terminal device is located in the external resource block allocation area, the first communication device can subtract x decibels from the maximum power backoff value defined in the current protocol as the final maximum power backoff value, that is, the maximum power backoff information is reduced by x decibels based on the protocol definition.
[0037] In a possible implementation, the maximum power backoff information corresponds to a channel bandwidth or a bandwidth of a network device.
[0038] Based on the implementation, the first communication device can use different maximum power backoff information for different channel bandwidths or bandwidths of network devices, so as to flexibly determine the maximum transmission power. For example, different x values can be used for different channel bandwidths or bandwidths of network devices.
[0039] In a possible implementation, the first communication device can further determine, according to the first information, a power consumption reduction value of the terminal device.
[0040] Based on the implementation, the first communication device can determine the power consumption reduction value according to the first information, so as to reduce the power consumption. For example, the power consumption reduction value p can be set, and the unit can be joules per bit. When the first communication device sends the first information, and / or when the second communication device allocates the transmission resource to the terminal device according to the first information, the first communication device can reduce the power consumption of p joules per bit when transmitting on the transmission resource.
[0041] In a possible implementation, the power consumption reduction value corresponds to a channel bandwidth or a bandwidth of a network device.
[0042] Based on the implementation, the first communication device can use different power consumption reduction values for different channel bandwidths or bandwidths of network devices, so as to flexibly determine the transmission power consumption. For example, different power consumption reduction values can be used for different channel bandwidths or bandwidths of network devices.
[0043] In a possible implementation, the first communication apparatus can further send fourth information, the fourth information being used to indicate a difference between the power of the terminal device on the first adjacent channel and the power of the terminal device on the second adjacent channel, and the difference being used to determine the scheduling priority of the terminal device.
[0044] Based on the implementation, the first communication apparatus can indicate the difference between the power of the first adjacent channel and the power of the second adjacent channel to the second communication apparatus, so that the second communication apparatus determines the scheduling priority of the terminal according to the difference. It can be understood that the second communication apparatus can preferentially schedule the terminal with a larger difference between the power of the first adjacent channel and the power of the second adjacent channel, to obtain a better effect of increasing the transmission power.
[0045] In a 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 a priority corresponding to the first threshold; or, when the difference belongs to a first power range, the scheduling priority is a first scheduling priority corresponding to the first power range, and when the difference belongs to a second power range, the scheduling priority is a second scheduling priority corresponding to the second power range, 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.

In the case where no special description is given, the "second device" in the present application can refer to the second device itself (for example, a base station or other network device), a component (for example, a functional module, a communication module, a processor, a circuit, a chip, or a chip system) in the second device, or a logic module or software capable of realizing all or part of the functions of the second device.

[0124] The specific implementation manners of the present application will be described below with reference to the accompanying drawings.
[0125] The embodiments of the present application can be applied to various communication systems. For example, the communication system can include a cellular system, such as a global system for mobile communications (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a universal mobile telecommunication system (UMTS), a 5th generation (5G) system or a new radio (NR), or a future communication system or other similar communication system. For another example, the communication system can include a non-cellular system, such as an ultra wide band (UWB) system, a worldwide interoperability for microwave access (WIMAX) communication system or a WiFi system.
[0126] Figure 1 shows a possible, non-limiting, schematic illustration of a system. As shown in Figure 1, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system can also include the Internet 300. The radio access network 100 can include at least one radio access network device (e.g., 110a and 110b in Figure 1) and at least one terminal (e.g., 120a-120j in Figure 1). The terminal is connected to the radio access network device in a wireless manner, and the radio access network device is connected to the core network in a wireless or wired manner. The core network device and the radio access network device can be independent and different physical devices, or can be integrated into the same physical device with the functions of the core network device and the logical functions of the radio access network device, or can be a physical device integrated with part of the functions of the core network device and part of the functions of the radio access network device. The terminals and the terminals, and the radio access network devices and the radio access network devices can be connected to each other in a wired or wireless manner. Figure 1 is only a schematic diagram, and the communication system can also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1.
[0127] In this application, unless otherwise specified, the access network device can represent the base station and other radio access network devices.
[0128] The access network device can be a device in the RAN that provides priority and / or wireless communication functions for the terminal device, referred to as a RAN device or (R)AN device. The RAN can be an access network in the 3rd generation partnership project (3GPP), for example, a 4th generation (4G), 5G, or future communication network. The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network of two or more of the above networks. The RAN device 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, an access node in a wireless fidelity (WiFi) system, a long range radio (LoRa) system, or a vehicle-to-everything system. The RAN device can also be a module or unit that completes part of the functions of the base station, for example, can be a CU, can be a DU, can be a CU-user plane (UP), or an RU, etc. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and above protocol layers (such as the radio resource control (RRC) layer and / or the service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement the functions of the PDCP layer below the protocol layer (such as the radio link control (RLC) layer, the media access control (MAC) layer, and / or the physical (PHY) layer, etc.). For specific descriptions of the above protocol layers, refer to the relevant technical specifications of the 3GPP. The CU and the DU can be separately arranged or can be included in the same network element, such as a baseband unit (BBU).The RU can be included in a radio frequency device or a radio frequency unit, for example, included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Any of the CU, CU-CP, CU-UP, DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. The wireless access network device can also be a macro base station (such as 110a in FIG. 1), or a micro base station or indoor station (such as 110b in FIG. 1), and can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the wireless access network device. In this application, the base station can be used as an example of the wireless access network device.
[0129] In some examples, the CU can be split into a CU-CP and a CU-UP, where the CU-CP is a logical node carrying the RRC layer and the PDCP control plane part (PDCP-C) layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, such as an access and mobility management function (AMF) network element in a 5G system. The CU-UP is a logical node carrying the SDAP layer and the PDCP-U (user plane part of PDCP) layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a user plane function (UPF) in a 5G system, is used to be responsible for the forwarding and receiving of data in the terminal device. The above configuration of the CU and the DU is only an example, and the CU and the DU can also be configured to have functions according to needs. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layer. For example, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are set in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet the delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.
[0130] In some examples, a DU can host logical nodes of RLC layer, MAC layer, higher physical layer (higher PHY) or other functions. In some examples, a DU can control at least one RU. The DU is connected with the RU through some interfaces, which can be a fronthaul interface.
[0131] In some examples, a CU can have no PDCP layer, e.g., only include RRC layer. The CU-CP can have no PDCP-C. The CU-UP can have no PDCP-U, or no CU-UP at all. In some examples, a DU can have no RLC layer, e.g., only have MAC and higher physical layer. In addition, in some examples, an O-RAN device can also have no CU, only include DU, i.e., have no RRC layer.
[0132] In some examples, a higher physical layer includes parts of PHY layer processing, e.g., forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. processing functions. In some examples, a RU is a logical node hosting lower physical layer (lower PHY) and radio frequency (RF) processing. In some examples, a RU can be a 3GPP TRP or RRH or other similar functional entity. In some examples, a lower physical layer includes parts of PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, etc. processing functions. A RU communicates with one or more terminals through a wireless link.
[0133] As an example, as shown in FIG. 2, an access network device can communicate with a core network device through a backhaul link. The access network device can also communicate with a user equipment (UE) through an air interface. The access network device can include a BBU and a RU, where the BBU can include a CU and a DU. A specific communication process can include: the BBU in the access network device communicates with the core network through the backhaul link, and / or the RU in the access network device communicates with at least one terminal through the air interface. The BBU (e.g., the DU) can communicate with at least one RU through a fronthaul link. The BBU and the RU can be co-located or not co-located. The BBU includes at least one CU and at least one DU, which can communicate through at least one midhaul link.
[0134] It can be understood that the CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an open CU (O-CU), the CU-CP can also be referred to as an open CU-CP (O-CU-CP), the CU-UP can also be referred to as an open CU-UP (O-CU-UP), the DU can also be referred to as an open DU (O-DU), and the RU can also be referred to as an open RU (O-RU). For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.
[0135] In some examples, the CU of the access network device is a logical node that carries the RRC layer, the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer and other control functions of the access network device. The CU is connected to network nodes such as core network through some interfaces, which can be E2 interface and the like. Optionally, the CU can have part of the functions of the core network. The CU (for example, the PDCP layer and higher layers) is connected to the DU (for example, the radio link control (RLC) layer and lower layers) through some interfaces, which can be F1 interface and the like. In some examples, these interfaces (for example, the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (for example, interface management, system information management, terminal context management, RRC message transmission, and the like). The F1AP is an application protocol of the F1 interface, which defines the signaling procedures of the F1 in some examples. The F1 interface supports the control plane F1-C and the user plane F1-U.
[0136] In some examples, the DU and the RU can be co-located or not co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split-CUS-Plane (LLS-CUS) interface over a fronthaul link. The LLS-CUS can include LLS-C interface and LLS-U interface providing C-Plane, and LLS-C interface and LLS-U interface providing U-Plane, respectively. In some examples, the C-Plane refers to real-time control between the DU and the RU. The DU and the RU exchange management information, such as management plane (M-Plane) (or M-Plane), via a LLS-M interface of the fronthaul link. The M-Plane refers to non-real-time management operation between the DU and the RU. The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected with one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of functions of the PHY layer closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of functions of the PHY layer closer to the intermediate radio frequency side.
[0137] It can be understood that embodiments of the present application do not limit specific technologies and specific device forms adopted by the access network device. The access network device can be a device including one or more of the BBU, the CU, the DU, or the RU. In addition, the CU can be divided into a network device in the access network or a network device in the core network, which is not limited in the present application.
[0138] In the present application, the network device can represent the access network device.
[0139] It can be understood that the network device can be referred to as a communication apparatus. For example, the network device can be understood as an apparatus having a network device function. For example, the apparatus for implementing the function of the network device can be the network device; or part of the elements in the network device, for example, the CU, the DU, or the RU, etc. The apparatus for implementing the function of the network device can also be an apparatus capable of supporting the network device to implement the function, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module, which can be installed in the network device or can be used in matching with the network device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.
[0140] The terminal device can also be referred to as a terminal or a terminal apparatus, a UE, a station (STA), a mobile station (MS), a mobile terminal (MT), or the like. The terminal device can be widely applied to various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart home, smart office, smart wear, smart transportation, smart city, and the like. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, and the like.
[0141] Embodiments of the present application do not limit specific technologies and specific device forms adopted by the terminal device. It can be understood that the terminal device can be referred to as a communication apparatus. For example, the terminal device can be understood as an apparatus with terminal device functions. For example, an apparatus for implementing the functions of the terminal device can be a terminal device; or can be an apparatus capable of supporting the terminal device to implement the functions, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module, which can be installed in the terminal device or can be used in matching with the terminal device.
[0142] The network device and the terminal device can be fixed in position or movable. The network device and / or the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on an airplane, a balloon, and a man-made satellite. Embodiments of the present application do not limit the application scenarios of the network device and the terminal device.
[0143] The roles of the network device and the terminal device can be relative. For example, the helicopter or the drone 120i in FIG. 1 can be configured as a mobile base station or an AP, and for a terminal 120j that accesses the wireless access network 100 through the 120i, the drone 120i is a network device; but for the network device 110a, the 120i is a terminal, that is, the 110a and the 120i communicate through a wireless air interface protocol. Of course, the 110a and the 120i can also communicate through an interface protocol between network devices and network devices, and at this time, the 120i is also a network device relative to the 110a. Therefore, the network device and the terminal device can be collectively referred to as a communication apparatus, and the 110a and the 110b in FIG. 1 can be referred to as a communication apparatus with a network device function, and the 120a-120j in FIG. 1 can be referred to as a communication apparatus with a terminal device function.
[0144] In this application, the network device and the terminal device, the network device and the network device, and the terminal device and the terminal device can communicate through the licensed spectrum, or through the unlicensed spectrum (or referred to as the license-exempt spectrum), or through the licensed spectrum and the unlicensed spectrum at the same time; can communicate through the spectrum below 6 gigahertz (GHz), or through the spectrum above 6 GHz, or through the spectrum below 6 GHz and the spectrum above 6 GHz at the same time. The embodiments of the present application do not limit the spectrum resources used for wireless communication.
[0145] In this application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, and "sending information" can include direct sending or indirect sending through other communication devices, communication apparatuses, units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, and "receiving information" can include direct receiving from YY or indirect receiving from YY through other communication devices, communication apparatuses, units or modules. In addition, "sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, "sending" or "receiving" can be performed between devices, for example, the base station and the terminal device perform sending or receiving through the air interface respectively, and "sending" or "receiving" can also be performed within the device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through the bus, wire or interface.
[0146] In this application, "for indicating" can include for directly indicating and for indirectly indicating. When describing that a certain "information" is for indicating A, it can include that the information directly indicates A or indirectly indicates A, and does not mean that A must be carried in the information.
[0147] The information indicated by one information is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by a protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly indicated to reduce the indication overhead caused by separately indicating the same information.
[0148] In addition, the specific indication manner can also be various existing indication manners, for example, but not limited to, the above-mentioned indication manners and various combinations thereof. The specific details of various indication manners can refer to the prior art, and will not be described herein. As can be seen from the above, for example, when multiple information of the same type needs to be indicated, the indication manner of different information can be different. In the implementation process, the required indication manner can be selected according to the specific needs, and the selected indication manner is not limited by the embodiments of the present application. In this way, the indication manner involved in the embodiments of the present application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information.
[0149] The to-be-indicated information can be sent as a whole, or can be divided into multiple sub-information and sent separately, and the sending period and / or sending occasion of the sub-information can be the same or different. The specific sending method is not limited by the present application. The sending period and / or sending occasion of the sub-information can be pre-defined, for example, pre-defined according to a protocol, or configured by the transmitting end device by sending configuration information to the receiving end device. Taking the configuration of the access network device to the terminal 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 message), MAC layer signaling and PHY layer signaling. The MAC layer signaling includes, for example, a MAC control element (CE). The PHY layer signaling includes, for example, at least one of downlink control information (DCI).
[0150] The first, second, and various numbers in the embodiments shown below are only for differentiation for convenience of description, and are not used to limit the scope of the embodiments of the present application. For example, different indication information is distinguished.
[0151] The "preset" or "predefined" or "preconfigured" can be implemented by pre-storing corresponding codes, tables or other means for indicating related information in devices (for example, including terminal devices and network devices), and can also be pre-provided in a protocol. The specific implementation manner is not limited in the present application. The "storage" can be stored in one or more memories. The one or more memories can be separately arranged or integrated in the encoder or decoder, processor, or communication device. The one or more memories can be part of the separately arranged and part of the integrated in the decoder, processor, or communication device. The type of memory can be any form of storage medium, which is not limited in the present application.
[0152] The "protocol" involved in the embodiments of the present application can refer to a standard protocol in the communication field, which can include the LTE protocol (such as technical specification (TS) 36, that is, the technical specification of TS36 series) of 3GPP, the NR protocol (such as the technical specification of TS38 series) and the related protocol applied to the future communication system, which is not limited in the present application.
[0153] The network architecture and service scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.
[0154] The technical terms and related technical solutions in the present application will be described below with reference to the accompanying drawings.
[0155] 1) PA and its nonlinear transmission characteristics.
[0156] PA converts a low power signal into a higher power signal in the transmitter, so as to overcome the signal attenuation between the transmitter and the receiver, and ensure that the receiver can receive a strong enough signal. The core semiconductor device of the PA is a transistor, which has a nonlinear characteristic, so the PA cannot maintain the ideal linearity expected by the transmitter. The nonlinear characteristic will cause the power amplifier to generate harmonic and intermodulation distortion. These distortions will worsen the transmission performance of the system, cause out-of-band radiation interference, increase the bit error rate, and reduce the error vector magnitude (EVM) performance. Referring to the PA nonlinear diagram shown in FIG. 3, the horizontal axis is the input power, and the vertical axis is the output power. As the input power increases, the relationship between the input and the output is no longer linear, so when the input power increases, the signal transmitted through the PA will experience nonlinear characteristics, causing nonlinear distortion of the signal.
[0157] wherein, since the efficiency of the PA is inversely related to distortion, the efficiency increases with the increase of nonlinear distortion, the efficiency is traded for distortion, and reducing the voltage will cause an increase in nonlinear distortion, so the efficiency of the PA can be improved by reducing the voltage.
[0158] 2) ACLR and spectral emission mask (SEM)
[0159] The 3GPP protocol defines the values of ACLR and SEM to constrain the out-of-band power value within a certain range.
[0160] ACLR refers to the ratio of the average power centered on the specified channel frequency to the average power centered on the adjacent channel frequency. If the measured adjacent channel power is greater than ≥-50 decibel-milliwatts (dBm), the ACLR should be higher than the value specified in Table 1.
[0161] Table 1
[0162] SEM is applied to the frequency (Δ fOOB ) from the positive edge of the allocated NR channel bandwidth (CBW). In this application, the channel bandwidth is the bandwidth allocated by the network device to the terminal, and the terminal device can perform reception and / or transmission within the bandwidth. Wherein, each transmission or reception can occupy part or all of the bandwidth in the channel bandwidth. The network device can schedule the transmission resource of the terminal within the channel bandwidth. The power emitted by any terminal device must not exceed the power level corresponding to the specified channel bandwidth specified in Table 2. In Table 2, the measurement bandwidth (MBW) is represented as the measurement bandwidth defined by the protected band.
[0163] Table 2
[0164] In Table 2, BWchannel represents the channel bandwidth.
[0165] The main difference between ACLR and SEM is that ACLR is a relative value and SEM is an absolute value, and the common point is that the requirements for the adjacent channels on both sides of the channel bandwidth are symmetrical. That is, the adjacent channels on both sides of the channel bandwidth have the same spurious power requirement, so it is necessary to suppress the spurious power of the adjacent channels on both sides of the channel bandwidth to the same level to avoid interference to other communication devices of the adjacent channels.
[0166] 3) Adjacent channel, or adjacent channel
[0167] The adjacent channel in the present application refers to the adjacent channel bandwidth on the left or right side of the channel bandwidth of the terminal device considered in the ACLR measurement. The width of the adjacent channel can be referred to as the ACLR measurement bandwidth. The ACLR measurement bandwidth is related to the subcarrier spacing (SCS) and the channel bandwidth of the terminal device. For example, the ACLR measurement bandwidth, the subcarrier spacing and the channel bandwidth of the terminal device satisfy: ACLR measurement bandwidth = subcarrier spacing * (12*N_RB+1) / 1000;
[0168] Wherein, N_RB represents the number of RBs contained in the channel bandwidth of the terminal. The number of RBs is related to the subcarrier spacing and the channel bandwidth of the terminal, and can be referred to the definition of the protocol.
[0169] Taking Table 3 as an example, when the channel bandwidth is 100MHz, if the subcarrier spacing is 30KHz, N_RB = 273.
[0170] Table 3
[0171] In Table 3, N / A represents not applicable.
[0172] 4) Maximum power reduction (MPR)
[0173] Because the positions of the resource blocks (RBs) allocated by the high-order modulation and the transmission bandwidth are different, the maximum output power allowed to be reduced by the terminal device is different. As shown in Table 3, the MPR definition when the power class (PC) is 3, wherein the main reason for the power reduction in the outer RB allocation area and the edge RB allocation area is ACLR and SEM.
[0174] Table 4
[0175] It can be understood that in Table 4, the upper index of the MPR value indicates the note index to which the MPR value is applicable. "Pi / 2 BPSK w Pi / 2 BPSK DMRS" indicates that Pi / 2 BPSK is used as the sequence of the demodulation reference signal (DMRS).
[0176] In the protocol, according to the number L CRB of RBs currently allocated to the terminal device and the total number N RB of RBs within the channel bandwidth, the range corresponding to the starting position RBStart (or RB start) of the RB is calculated to define the range to which the inner RB allocation region belongs. The edge RB allocation region is the region of 1 or 2 RBs on the left or right. The remaining region is the inner RB allocation region, and the division of the region is shown in FIG. 4. The inner RB allocation region is mainly limited by in-band indicators, such as EVM and in-band emission (IBE). The inner RB allocation region and the edge RB allocation region are mainly limited by out-of-band indicators, such as ACLR and SEM. Among them, the edge RB allocation region has a higher power spectrum density due to being close to the edge and thus often has a greater power backoff.
[0177] One of the factors affecting the MPR is the RB allocation region. As can be clearly seen from FIG. 4, there are mainly three regions, i.e., the edge RB allocation region, the outer RB allocation region, and the inner RB allocation region. Among them, the inner RB allocation region is represented by the region enclosed by the thick line in FIG. 4. Taking a channel bandwidth of 100 MHz as an example, when the subcarrier spacing is 30 KHz, 100 MHz can contain N RB = 273 RBs. Hereinafter, the value range of RBStart is any integer in 0 to 272, and the value range of L CRB is any integer in 1 to 273 are taken as examples for introduction. In addition, in addition to the above value ranges, RBStart and / or L CRB can also have other value ranges. For example, the value range of RBStart can also be 1 to 273, etc.
[0178] Among them, if the number L CRB of allocated RBs (or the RB length RB length) is less than or equal to 2, and the starting position RBStart of the RB is located on the upper and lower edges of the channel bandwidth, it is the edge RB allocation region.
[0179] The starting position RBStart of the RB and the number L CRB of allocated RBs in the inner RB allocation region satisfy the following conditions: RBStart,Low≤RBStart≤RBStart,High; L CRB≤ceil(N_RB / 2).
[0180] where RBStart,Low = max(1, floor(L CRB / 2)) represents the minimum value of the inner RB allocation region RBStart, and RBStart,High = N RB - RBStart,Low - L CRB represents the maximum value of the inner RB allocation region RBStart. N RB is the maximum number of RBs (i.e., the total number of RBs) within the channel bandwidth of the terminal device, floor() represents the floor function, and ceil() represents the ceiling function. For example, floor(L CRB / 2) is the maximum integer less than or equal to L CRB / 2, and ceil(N RB / 2) is the minimum integer greater than or equal to N RB / 2.
[0181] If neither belongs to the inner RB allocation region nor the edge RB allocation region, it is the outer RB allocation region.
[0182] Generally, the MPR has the following basic rules: the MPR of a low-order modulation mode is less than or equal to the MPR of a high-order modulation mode, 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.
[0183] Hereinafter, the inner RB allocation region can be referred to as an inner resource region, the outer RB allocation region can be referred to as an outer resource region, and the edge RB allocation region can be referred to as an edge resource region.
[0184] 5) Memory effect
[0185] When the measurement of the amplitude distortion, the phase distortion, or the intermodulation distortion of the power amplifier is no longer solely dependent on the change in the signal input power, but is also affected by the change in the frequency of the input signal envelope, especially the upper and lower sidebands of the intermodulation distortion signal will become asymmetric, it is particularly important to study the memory effect in the non-linear characteristics of the amplifier. The memory effect refers to the fact that the characteristics of the current time of the device are affected by the state of the previous time, just like the device has memory, so this characteristic is called memory effect. When the wideband OFDM signal passes through the PA, significant memory effect will be generated, the most important manifestation is that the ACLR on the left side of the channel bandwidth and the ACLR on the right side of the channel bandwidth are asymmetric, that is, the power of the left and right adjacent channels is asymmetric. Among them, the ACLR on the left side of the channel bandwidth refers to the ratio of the average power of the channel bandwidth to the average power of the adjacent channel on the left side of the channel bandwidth. The ACLR on the right side of the channel bandwidth refers to the ratio of the average power of the channel bandwidth to the average power of the adjacent channel on the right side of the channel bandwidth. The channel bandwidth can refer to all available resources within the carrier.
[0186] In this application, left side can represent lower frequency, and right side can represent higher frequency. Correspondingly, the type of memory effect is divided into left type and right type.
[0187] In this application, left represents that the ACLR of the left adjacent channel of the channel bandwidth is higher than the ACLR of the right adjacent channel, or in other words, the power of the left adjacent channel of the channel bandwidth is lower than the power of the right adjacent channel. As shown in FIG. 5, the power distribution diagram of the PA with left memory effect in the allocated channel bandwidth, the left adjacent channel and the right adjacent channel shows that the power of the left adjacent channel is lower than the power of the right adjacent channel.
[0188] Right represents that the ACLR of the right adjacent channel of the channel bandwidth is higher than the ACLR of the left adjacent channel, or in other words, the power of the right adjacent channel of the channel bandwidth is lower than the power of the left adjacent channel. As shown in FIG. 6, the power distribution diagram of the PA with right memory effect in the allocated channel bandwidth, the left adjacent channel and the right adjacent channel shows that the power of the right adjacent channel is lower than the power of the left adjacent channel.
[0189] It can be understood that the meanings represented by left and right in this application can also be replaced with each other. For example, left represents that the ACLR of the right adjacent channel of the channel bandwidth is higher than the ACLR of the left adjacent channel, or in other words, the power of the right adjacent channel of the channel bandwidth is lower than the power of the left adjacent channel, and right represents that the ACLR of the left adjacent channel of the channel bandwidth is higher than the ACLR of the right adjacent channel, or in other words, the power of the right adjacent channel of the channel bandwidth is lower than the power of the left adjacent channel.
[0190] Among them, the memory effect is mainly related to the manufacturing process of transistor devices, the self-heating of active power devices, the frequency bandwidth and bias of input signal envelope, and the design quality of matching network, etc. It is a basic characteristic of a PA.
[0191] It can be seen that, due to the existence of the memory effect of the PA, the power of the left adjacent channel and the power of the right adjacent channel are asymmetric, causing the maximum transmit power that the terminal device can use in the left and right edge regions within the channel bandwidth to be different, or, in the case that the maximum transmission bandwidth in the left and right edge regions is the same, the power consumption of the PA is different. For example, in the case of keeping the PA power consumption unchanged, the maximum transmit power that the terminal device can use in the channel bandwidth is lower on the side edge of the adjacent channel ACLR, and the maximum transmit power that the terminal device can use in the channel bandwidth is higher on the side edge of the adjacent channel ACLR. Due to the existence of the memory effect, in order to suppress the left and right adjacent channel powers to the same level, the in-band maximum transmit power in the left and right sides within the channel bandwidth is different. That is, when the network device schedules the terminal to transmit in the channel bandwidth, the spurious power of the adjacent channel when the scheduling resource is close to the adjacent channel with lower ACLR is greater than the spurious power of the adjacent channel when the scheduling resource is close to the adjacent channel with higher ACLR.
[0192] Currently, in the process of scheduling the uplink transmission of the terminal device by the network device, the scheduling resource is not determined according to the type of the memory effect of the terminal. If the network device schedules the terminal to transmit in the channel bandwidth close to the adjacent channel with lower ACLR, due to the greater spurious power of this side adjacent channel, the terminal device will adopt a greater maximum power backoff value, and the maximum transmit power of the terminal is smaller. When the network device schedules the terminal to transmit in the channel bandwidth close to the adjacent channel with higher ACLR, the spurious power of this side adjacent channel is smaller, and the terminal device can adopt a smaller maximum power backoff value, and the maximum transmit power of the terminal is greater. Therefore, compared with scheduling the terminal to transmit in the channel bandwidth close to the adjacent channel with higher ACLR, scheduling the terminal to transmit in the channel bandwidth close to the adjacent channel with lower ACLR will cause the maximum transmit power of the terminal to decrease.
[0193] Therefore, how to reasonably schedule resources to improve the maximum transmit power of the terminal device is a technical problem to be solved at present.
[0194] In order to solve the above technical problem, an embodiment of the present application provides a communication method. In the method, the terminal device can indicate or provide the memory effect type to the network device, and accordingly, the network device schedules resources according to the memory type of the terminal device, so that the terminal device can transmit in the position of the side of the channel bandwidth that supports a larger maximum transmit power, to improve the maximum transmit power. It can be understood that the increase of the maximum transmit power can increase the transmit power of the terminal device in some cases.
[0195] The technical solutions in the present application will be described below in combination with the flow shown in S101-S103 in FIG. 7.
[0196] In FIG. 7, the execution subject is taken as an example of a terminal device and a network device. The actions performed by the terminal device can be replaced by a first communication device. The first communication device can be a terminal device or a component (such as a functional module or a chip) applicable to a terminal device. The actions performed by the network device can be replaced by a second communication device. The second communication device can be a network device (such as a base station) or a component (such as a functional module or a chip) applicable to a network device.
[0197] S101: The terminal device sends first information. Correspondingly, the network device receives the first information.
[0198] In this application, the first information can be used to indicate the type of the memory effect of the terminal device, or in other words, the first information can include the type information of the memory effect. The type of the memory effect can be left or right. When the type of the memory effect is left, it can mean that the power of the left adjacent channel of the channel bandwidth of the terminal device is lower than the power (or the spurious power) of the right adjacent channel, as shown in FIG. 5; or it can 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. Hereinafter, the type of the memory effect is taken as an example of left, but it does not exclude that the power of the right adjacent channel of the channel bandwidth is lower than the power of the left adjacent channel is defined as the type of the memory effect is right, and / or, it does not exclude that the ACLR of the right adjacent channel of the channel bandwidth is higher than the ACLR of the left adjacent channel is defined as the type of the memory effect is right.
[0199] When the type is right, it can mean that the power of the right adjacent channel of the channel bandwidth of the terminal device is lower than the power of the left adjacent channel, as shown in FIG. 6; or it can 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. Hereinafter, the type of the memory effect is taken as an example of right, but it does not exclude that the power of the left adjacent channel of the channel bandwidth is lower than the power of the right adjacent channel is defined as the type of the memory effect is right, and / or, it does not exclude that the ACLR of the left adjacent channel of the channel bandwidth is higher than the ACLR of the right adjacent channel is defined as the type of the memory effect is right.
[0200] In the present application, the type of memory effect can be determined by terminal device measurement. As an example, the terminal device can measure the ACLR of the left adjacent channel (denoted as ACLR_left) and the ACLR of the right adjacent channel (denoted as ACLR_right) when the channel bandwidth is signaled, and determine the type of memory effect of the terminal device according to the ACLR of the left adjacent channel and the ACLR of the right adjacent channel. Wherein, if the ACLR of the left adjacent channel and the ACLR of the right adjacent channel satisfy the following condition, it represents that the type of memory effect of the terminal device is left: ACLR_left - ACLR_right > x dB, x is a positive integer. Or, if the ACLR of the left adjacent channel and the ACLR of the right adjacent channel satisfy the following condition, it represents that the type of memory effect of the terminal device is right: ACLR_right - ACLR_left > x dB, x is a positive integer.
[0201] In addition, the type of memory effect can also be configured in the terminal device factory configuration, and the terminal device does not need to perform measurement. It can be understood that if the PAs of multiple terminal devices are of the same batch, the same model and / or the same manufacturer, the types of memory effect of the multiple terminal devices can be the same or different.
[0202] 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 the power of the terminal device in the second adjacent channel, or in other words, the first information can be used to indicate that the ACLR of the terminal device in the first adjacent channel is higher than the ACLR of the terminal device in the second adjacent channel, at this time it can be considered that the type of memory effect of the terminal device is left. In other words, when the first information includes the type information of the memory response, and the type information indicates that the type is left, 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.
[0203] Wherein, the frequency of the first adjacent channel is lower than the frequency of the second adjacent channel, wherein the frequency of the first adjacent channel is for example the center frequency or the highest frequency of the first adjacent channel, and the frequency of the second adjacent channel is for example the center frequency or the lowest frequency of the second adjacent channel. In other words, the first adjacent channel is the left adjacent channel of the channel bandwidth, and the second adjacent channel is the right adjacent channel of the channel bandwidth. At this time, it can be considered that the type of memory effect indicated by the first information is left. As shown in FIG. 5, the left adjacent channel can be used as an example of the first adjacent channel, and the right adjacent channel can be used as an example of the second adjacent channel. As can be seen from FIG. 5, the power of the first adjacent channel is lower than the power of the second adjacent channel, at this time the type of memory effect can be left.
[0204] The power of the 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 the terminal device transmits a signal in the channel bandwidth. The power of the terminal device in the second adjacent channel can be understood as the spurious power or interference power detected by the terminal device in the second adjacent channel when the terminal device transmits a signal in the channel bandwidth.
[0205] In addition, the first information can be 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 in other words, the first information can be 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. At this time, the type of the memory effect of the terminal device can be right. In other words, when the first information includes type information of the memory response and the type information indicates that the type is right, 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. As shown in FIG. 6, the left adjacent channel can be an example of the first adjacent channel, and the right adjacent channel can be an example of the second adjacent channel. It can be seen that the power of the first adjacent channel in FIG. 6 is higher than the power of the second adjacent channel, and at this time, the type of the memory effect can be right.
[0206] It can be understood that the first information can occupy 1 bit. When the value of the bit is a first value, it represents that the type of the memory effect of the terminal device is left, and when the value of the bit is a second value, it represents that the type of the memory effect of the terminal device is right. The first value is different from the second value. For example, the first value is 0, and the second value is 1; or the first value is 1, and the second value is 0.
[0207] S102: The network device determines the transmission resource of the terminal device according to the first information.
[0208] The transmission resource of the terminal device can be understood as the transmission bandwidth of the terminal device, indicating the transmission resource available to the terminal device configured by the network device.
[0209] It can be understood that the transmission resource of the terminal device can be RB granularity. In S102, the network device can determine the starting position of the RB and / or the number of RBs allocated to the terminal device according to the first information. In addition, the transmission resource of the terminal device can also be bandwidth granularity, etc., which is not specifically limited.
[0210] In S102, the network device can determine the transmission resource of the terminal according to the first information and according to the channel bandwidth of the terminal. The channel bandwidth of the terminal can be configured by the network device within the bandwidth range of the network device. The bandwidth of the network device is the total bandwidth of the network device in an operator network.
[0211] For example, the network device configures two component carriers (CCs), denoted as CC#1 and CC#2, where the bandwidths of CC#1 and CC#2 are 100 megahertz (MHz) and 60 MHz respectively, i.e., the bandwidth of the network device is 160 MHz. The terminal device can be configured with CC#1 and / or CC#2. Taking the terminal device configured with CC#1 as an example, the channel bandwidth of the terminal device is the bandwidth of CC#1, i.e., 100 MHz.
[0212] In a possible embodiment, if the first information indicates that the type of the terminal device is left, i.e., the power of the first adjacent channel of the terminal device is lower than the power of the second adjacent channel, the network device can preferentially allocate, as the transmission bandwidth of the terminal device, the bandwidth close to the left edge in the channel bandwidth or the bandwidth of the network device. Taking FIG. 8A as an example, the channel bandwidth is 100 MHz, and taking the transmission bandwidth of the terminal device as 50 MHz as an example, when the type of the terminal device is left, the network device can allocate 50 MHz on the left of the center frequency of the channel bandwidth as the transmission resource of the terminal device.
[0213] In addition, the network device can determine the transmission resource of the terminal device according to the first information and according to the bandwidth of the network device.
[0214] Taking FIG. 8B as an example, the bandwidth of the network device is 160 MHz, and taking the transmission bandwidth of the terminal device as 100 MHz as an example, if the first information indicates that the type of the terminal device is left, in example 1, the network device can allocate 100 MHz on the left of the center frequency of the bandwidth of the network device as the transmission resource of the terminal device.
[0215] Similarly, if the first information indicates that the type of the terminal device is right, i.e., the power of the second adjacent channel of the terminal device is lower than the power of the first adjacent channel, the network device can preferentially allocate, as the transmission bandwidth of the terminal device, the bandwidth close to the right edge in the channel bandwidth. Taking FIG. 8A as an example, the network device can allocate 50 MHz on the right of the center frequency of the channel bandwidth as the transmission resource of the terminal device.
[0216] Taking FIG. 8B as an example, the bandwidth of the network device is 160 MHz, and taking the transmission bandwidth of the terminal device as 100 MHz as an example, if the first information indicates that the type of the terminal device is right, in example 2, the network device can allocate 100 MHz on the right of the center frequency of the bandwidth of the network device as the transmission resource of the terminal device.
[0217] In another possible embodiment, the network device can determine the transmission resource of the terminal device according to at least one of the external resource region, the internal resource region or the 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 refer to FIG. 4 and the description of FIG. 4.
[0218] In this application, the external resource region can include an external left resource region and an external right resource region. That is, the network device can determine the transmission resource of the terminal device according to at least one of the external left resource region, the external right resource region, the internal resource region or the edge resource region and the first information.
[0219] It can be understood that at least one of the external resource region, the external left resource region, the external right resource region, the internal resource region or the edge resource region can be determined according to the channel bandwidth or the bandwidth of the network device.
[0220] Optionally, in the case that 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 external resource region, the external left resource region, the external right resource region, the internal resource region or the edge resource region according to the bandwidth of the network device to improve the maximum transmission power. For example, the RB in the external resource region according to the channel bandwidth may, when the above-mentioned regions are determined according to the bandwidth of the network device, belong to the internal resource region, and therefore, in the case that the above-mentioned regions are determined according to the bandwidth of the network device, the terminal can use a greater maximum transmission power to perform transmission in the RB.
[0221] The external resource region, the internal resource region and the edge resource region shown in FIG. 4 can be determined according to the channel bandwidth of the terminal or the bandwidth of the network device. For example, the bandwidth of the network device is 160 MHz and the channel bandwidth is 100 MHz. It can be understood that, taking the subcarrier spacing of 30 KHz as an example, if the external resource region, the internal resource region and the edge resource region shown in FIG. 4 are determined according to the bandwidth of the network device, the total number of RBs N_RB=435. Taking the subcarrier spacing of 30 KHz as an example, if the external resource region, the internal resource region and the edge resource region shown in FIG. 4 are determined according to the channel bandwidth of the terminal, the total number of RBs N_RB=273.
[0222] The external right resource region can also be referred to as an external right RB allocation region. If the external right resource region is determined according to the channel bandwidth, the number of RBs on the right side of the center frequency of the channel bandwidth in this region is greater than that on the left side, i.e., the number of RBs with a frequency higher than the center frequency of the channel bandwidth is greater than that with a frequency lower than the center frequency of the channel bandwidth.
[0223] As shown in FIG. 9, the black area represents the outer right resource region, and the sum of the white area and the black area is the complete channel bandwidth. In addition, the outer left resource region can also be referred to as an outer left RB allocation region, in which the number of RBs on the left of the center frequency of the channel bandwidth is greater than the number of RBs on the right. It can also be understood that the outer left resource region is a region in the outer resource region other than the outer right resource region.
[0224] As shown in FIG. 4, the dashed lines on the left and right respectively represent the outer left RB allocation region and the outer right RB allocation region in the outer RB allocation region.
[0225] As an example, the number of RBs with a frequency higher than the center frequency of the channel bandwidth is greater than the number of RBs with a frequency lower than the center frequency of the channel bandwidth, which can be described as: RBStart+L_CRB-N_RB / 2>N_RB / 2-RBStart.
[0226] Moving the term can obtain: 2RBStart+L_CRB>N_RB; (Formula 1)
[0227] RBStart represents the starting position of the first transmission resource block in the transmission resource, L_CRB represents the number of total transmission resource blocks in the transmission resource, and N_RB represents the total number of transmission resource blocks in the channel bandwidth.
[0228] In addition, if the outer right resource region is determined according to the bandwidth of the network device, the number of RBs on the right of the center frequency of the bandwidth of the network device is greater than the number of RBs on the left, that is, the number of RBs with a frequency higher than the center frequency of the bandwidth of the network device is greater than the number of RBs with a frequency lower than the center frequency of the bandwidth of the network device.
[0229] As an example, the outer right resource region is determined according to the bandwidth of the network device, and the outer right resource region still satisfies Formula 1, where N_RB in Formula 1 represents the total number of transmission resource blocks in the bandwidth of the network device.
[0230] As an example, when determining the transmission resource of the terminal device according to at least one of the external resource region, the internal resource region or the edge resource region and the first information, the network device can determine the transmission resource from at least one of the external resource region, the internal resource region or the edge resource region according to the type of the memory effect of the terminal device indicated by the first information. That is, the network device can determine the transmission resource of the terminal device from at least one of the external left resource region, the external right resource region, the internal resource region or the edge resource region according to the type of the memory effect of the terminal device indicated by the first information. When determining the transmission resource of the terminal device, the network device can also refer to the amount of data to be transmitted by the terminal device, the position or width of the other allocated transmission resources in the bandwidth, and the like.
[0231] Taking the memory effect of the terminal device as right as an example, the network device can determine the transmission resource of the terminal device from the external right resource region after determining the transmission resource of the terminal device from the external resource region. For example, the network device can determine the RB start position RBStart and the number of allocated RBs L CRB in the external right RB allocation region shown in FIG. 4.
[0232] FIG. 8A can be an example of this embodiment. Taking the subcarrier spacing as 30 KHz as an example, the network device can determine RBStart=0 and L CRB=136 from the external left RB allocation region shown in FIG. 4 as the transmission resource of the terminal device, which can be allocated to the terminal device with the memory effect type of left. The transmission resource can be understood as 136 RBs in the 50 MHz to the left of the center frequency of the bandwidth shown in FIG. 8A. The bandwidth can be the channel bandwidth. In addition, the network device can determine RBStart=136 and L CRB=137 from the external right RB allocation region shown in FIG. 4 as the transmission resource of the terminal device, which can be allocated to the terminal device with the memory effect type of right. The transmission resource can be understood as 136 RBs in the 50 MHz to the right of the center frequency of the bandwidth shown in FIG. 8A and the RBs containing the center frequency of the bandwidth.
[0233] In addition, the network device can determine RBStart=0 and L CRB=137 as the transmission resource of the terminal device, which can be allocated to the terminal device with the memory effect type of left. The transmission resource can be understood as 136 RBs in the 50MHz on the left of the center frequency of the bandwidth shown in FIG. 8A and the RB containing the center frequency of the bandwidth. In addition, the network device can determine RBStart=137 and L CRB=136 as the transmission resource of the terminal device from the external right RB allocation area, which can be allocated to the terminal device with the memory effect type of right. The transmission resource can be understood as 136 RBs in the 50MHz on the right of the center frequency of the bandwidth shown in FIG. 8A.
[0234] Similarly, FIG. 8B can also be used as an example of the embodiment. For example, the subcarrier spacing is 30KHz, the bandwidth of the network device is 160MHz, that is, it contains 435 RBs, and the network device can determine L CRB=273 as the transmission resource from the external left RB allocation area shown in FIG. 4, which can be allocated to the terminal device with the memory effect type of left. The network device can also determine L CRB=273 as the transmission resource of the terminal device from the external right RB allocation area shown in FIG. 4, which can be allocated to the terminal device with the memory effect type of right.
[0235] In addition, the network device can also determine L CRB=273 as the transmission resource from the external left RB allocation area shown in FIG. 4. The network device can also determine L CRB=273 as the transmission resource of the terminal device with the memory effect type of left from the external right RB allocation area shown in FIG. 4.
[0236] It can be understood that if the network device allocates the transmission resource for the terminal according to the first information and the bandwidth of the network device, and the transmission resource is beyond the range of the channel bandwidth of the terminal, the terminal can perform transmission in the transmission resource allocated by the network device in a carrier aggregation (CA) manner. The transmission mode of carrier aggregation does not belong to the limitation of the present application.
[0237] For example, the 160MHz shown in FIG. 8B is the bandwidth of the network device, and the 100MHz on the left is the channel bandwidth of the terminal. If the network device allocates the transmission resource of 100MHz on the right to the terminal, as shown in example 2, the terminal can perform CA transmission in the 100MHz. Specifically, in the 100MHz, 40MHz of CC#1 and 60MHz of CC#2 are contained, so the terminal performs CA transmission on CC#1 and CC#2.
[0238] S103: The network device sends the scheduling information. Correspondingly, the terminal device receives the scheduling information. The terminal device can determine the transmission resource according to the scheduling information.
[0239] The scheduling information is carried in DCI, for example.
[0240] Based on the above S101 to S103, the network device can allocate the transmission resource for the terminal device according to the type of the memory effect of the terminal device reported by the terminal device, and schedule the terminal device to transmit at the side position of the channel bandwidth supporting a larger maximum transmission power, so as to improve the maximum transmission power.
[0241] Through simulation and real signal test, if the memory effect of the terminal device is right, or in other words, if the first information indicates that the type of the memory effect is right, or in other words, 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 in other words, 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 for the terminal device from the external right side RB allocation area, which can effectively reduce the power of the terminal device in the first adjacent channel, wherein the first adjacent channel is the adjacent channel corresponding to the higher power, so that the power backoff value for suppressing the power of the adjacent channel can be reduced, which means that the maximum transmission power of the terminal device can be improved.
[0242] Similarly, if the memory effect of the terminal device is left, or in other words, if the first information indicates that the type of the memory effect is left, or in other words, 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 in other words, 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 for the terminal device from the external left side RB allocation area, which can effectively reduce the power of the terminal device in the second adjacent channel, wherein the second adjacent channel is the adjacent channel corresponding to the higher power, so that the power backoff value for suppressing the power of the adjacent channel can be reduced, which means that the maximum transmission power of the terminal device can be improved.
[0243] In a possible embodiment, the terminal device can also send second information. Correspondingly, the network device can receive the second information.
[0244] The second information can be used to indicate the frequency band corresponding to the first information. The frequency band can be understood as the frequency band to which the first information is applicable. That is, when the terminal device sends the first information and the second information to the network device, it means that the type of memory effect of the terminal device in the frequency band indicated by the second information is the type of memory effect indicated by the first information. Correspondingly, the network device can determine whether to allocate the transmission resource of the terminal device according to the first information within the channel bandwidth according to 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 the transmission resource of the terminal device according to the first information within the channel bandwidth. Wherein, when the center frequency and / or the boundary frequency of the channel bandwidth is located in 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 work in different frequency bands, and the first information can be used to indicate the type of memory effect when the terminal device works in part or all of the frequency bands. Wherein, the type of memory effect can be the same or different when the terminal device works in different frequency bands. The terminal device can indicate the type of memory effect in any one or more frequency bands through the first information and the second information.
[0245] Similarly, the network device can determine whether to allocate the transmission resource of the terminal device according to the first information within the bandwidth of the network device according to the frequency band corresponding to the first information.
[0246] It can be understood that if the second information from the terminal device is received, the network device can determine the transmission resource according to the first information and the second information when performing S103. The network device determines the transmission resource according to the first information and the third information, which can be understood as that the network device determines the transmission resource of the terminal device according to the first information and the channel bandwidth after determining that the frequency band corresponding to the first information matches the frequency band of the channel bandwidth according to the second information, or the network device determines the transmission resource of the terminal device according to the first information and the bandwidth of the network device after determining that the frequency band corresponding to the first information matches the frequency band of the network device according to the second information. Wherein, the way of determining the transmission resource of the terminal device according to the first information can refer to the description in S103, which will not be repeated here.
[0247] 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 terminal device level capability or configuration. For the scenario that 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 the network device can be applicable to the first information, that is, the network device can determine the transmission resource of the terminal device according to the first information in S102.
[0248] In this example, the second information can include an identifier representing the terminal device level.
[0249] 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 a band combination level. For a scenario where the terminal device is applicable to one or more band combinations, when the frequency (such as a center frequency or a boundary frequency) of the channel bandwidth configured by the network device for the terminal device belongs to the band combination, i.e., in S102, the network device can determine the transmission resource of the terminal device according to the first information. Or, when the frequency of the bandwidth of the network device belongs to the band combination, i.e., in S102, the network device can determine the transmission resource of the terminal device according to the first information.
[0250] In this example, the second information can contain an identification or index representing the one or more band combinations corresponding to the first information.
[0251] As another example, the second information can be used to indicate that the first information corresponds to one or more bands, or in other words, the second information is used to indicate that the first information is a capability or configuration at a band level. For a scenario where the terminal device is applicable to one or more bands, when the frequency of the channel bandwidth configured by the network device for the terminal device belongs to the band, i.e., in S102, the network device can determine the transmission resource of the terminal device according to the first information. Or, when the frequency of the bandwidth of the network device belongs to the band, i.e., in S102, the network device can determine the transmission resource of the terminal device according to the first information.
[0252] In this example, the second information can contain an identification or index representing the one or more bands corresponding to the first information.
[0253] In a possible embodiment, the terminal device can further send third information. Correspondingly, the network device can receive the third information. In S103, the network device can determine the transmission resource according to the first information and the third information.
[0254] The third information can be used to indicate a power level corresponding to the first 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.
[0255] The power level corresponding to the first information can be understood as the power level to which the first information is applicable. That is, when the terminal device sends the first information and the third information to the 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 type of memory effect indicated by the first information. Correspondingly, the network device can determine whether to allocate the transmission resource of the terminal device according to 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 the power level corresponding to the first information includes the power level of the terminal device, the transmission resource of the terminal device can be determined according to the first information. That is, the terminal device can work at different power levels, and the first information can be used to indicate the type of memory effect when the terminal device works at part or all of the power levels.
[0256] It can be understood that if the third information from the terminal device is received, the network device can determine the transmission resource according to the first information and the third information when performing S103. Determining the transmission resource according to the first information and the third information can be understood as: the network device determines the transmission resource of the terminal device according to the first information after determining that the power level corresponding to the first information is the same as the power level of the terminal device or the power level corresponding to the first information includes the power level of the terminal device according to the third information. The way of determining the transmission resource of the terminal device according to the first information can be referred to the description in S103, which will not be repeated here.
[0257] As an example, the power level corresponding to the first information can be power level 1, power level 1.5, power level 2, or power level 3, etc., which is not specifically limited.
[0258] It can also be understood that if the network device receives the first information, the second information and the third information from the terminal device, it can determine the transmission resource according to the first information, the second information and the third information when performing S103. Specifically, the network device can determine the transmission resource of the terminal device according to 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) according to the second information, and after determining that the power level corresponding to the first information is the same as the power level of the terminal device or the power level corresponding to the first information includes the power level of the terminal device according to the third information.
[0259] In a possible embodiment, one or more of the first information, the second information and the third information can be carried in the terminal device capability information. That is, the terminal device can send one or more of the first information, the second information and the third information through the terminal device capability report.
[0260] Optionally, before S101, the network device can send a memory effect type request to the terminal device, to request the first information. As an example, the memory effect type request is a capability query request, and accordingly, the terminal device can carry the first information in terminal device capability information.
[0261] Optionally, the terminal device capability information can further include switch information, to indicate whether the terminal device opens the memory effect type indication. If the terminal device opens the memory effect type indication, the terminal device capability information can include the first information, and optionally, the second information and / or the third information. The switch information can also have other names, which are not specifically required in the present application.
[0262] It can be understood that the switch information can occupy 1 bit in the terminal device capability information. When the value of the bit is a first value, it represents opening the memory effect type indication of the terminal device, or in other words, opening the memory effect type report of the terminal device. When the value of the bit is a second value, it represents not opening the memory effect type indication of the terminal device, or in other words, not opening the memory effect type report of the terminal device. The first value is different from the second value. For example, the first value is 0, and the second value is 1; or the first value is 1, and the second value is 0.
[0263] In a possible embodiment, the terminal device can determine the maximum power backoff information according to the first information. In the present application, since the network device can determine the transmission resource allocated to the terminal device according to the first information, the terminal device can use a larger maximum transmit power to improve the transmit power. For example, after determining the MPR according to the table shown in Table 4, the terminal device can reduce the value of MPR to achieve a larger transmit power. For example, for the external RB allocation area, the reduction value x of MPR can be set based on the MPR value shown in Table 4, and after querying the corresponding MPR value according to Table 4, the MPR value is reduced by x dB as the maximum power backoff value. In other words, in the case of determining the transmission resource of the terminal device according to the first information, the maximum power backoff information of the terminal device can be, for example, the maximum power backoff value determined according to the MPR value and x.
[0264] For example, according to Table 4, the MPR value of the external resource area is originally 2 dB when the coding mode is 16QAM. 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 the power level 2, i.e., the maximum transmit power of the terminal device is 26 dBm, as an example, the transmit power of the terminal device can be 26-(MPR-x), and taking x = 1 as an example, the transmit power of the terminal device can be 25 dBm.
[0265] As an example, the value of x and the manner of determining the maximum power backoff information can be added as a new note in Table 4 of the protocol. For example, the following note is added: for the external RB allocation area, if at least one of the following conditions is met: the terminal device is indicated to enable the memory effect type, the terminal device sends the first information, or the network device determines the transmission resource of the terminal device according to the first information, the terminal device determines the maximum transmit power according to x, or the terminal device determines the maximum transmit power according to MPR and x, or the terminal device determines the maximum transmit power according to (MPR-x). Wherein, MPR can be greater than or equal to 1, and x is greater than 0.
[0266] 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 bandwidths of network devices can correspond to different maximum power backoff information. For example, different channel bandwidths can correspond to different values of x, and when the transmission resource of the terminal is determined according to the first information and the channel bandwidth, the terminal can determine the maximum transmit power according to the maximum power backoff information corresponding to the channel bandwidth. For another example, different bandwidths of network devices can correspond to different values of x, and when the transmission resource of the terminal is determined according to the first information and the bandwidth of the network device, the terminal can determine the maximum transmit power when transmitting a signal in the transmission resource according to the maximum power backoff information corresponding to the bandwidth of the network device. For example, the MPR table shown in Table 4 can be added with a note, which includes the correspondence between the value of x and the channel bandwidth, and / or the correspondence between the value of x and the bandwidth of the network device.
[0267] In a possible embodiment, the terminal device can determine the transmit power according to the transmission resource and the operator information of the first adjacent channel (i.e., the left adjacent channel) or the operator information of 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.
[0268] If the transmission resource of the terminal device belongs to the left external resource region, the terminal device can determine the maximum transmit power of the transmission resource according to the operator information of the first adjacent channel. For example, as shown in FIG. 10, the bandwidth of the network device is 160 MHz, of which 100 MHz with a higher frequency is configured as the channel bandwidth of the terminal device, and 60 MHz with a lower frequency overlaps with the first adjacent channel of the terminal device. If the transmission resource (represented by a black area in FIG. 10) of the terminal device is located in the left external resource region, and the terminal device determines, according to the operator information of the first adjacent channel, that the operator of the first adjacent channel is the same as the operator of the channel bandwidth in which the transmission resource of the terminal device is located, the terminal device can reduce the value of MPR after determining the MPR according to the table shown in Table 4, so as to achieve a greater transmit power. Since the first adjacent channel and the channel bandwidth of the terminal device belong to the same operator, the spurious power of the terminal in the first adjacent channel falls within the bandwidth of the base station, which is not limited by the ACLR and SEM of the channel bandwidth of the terminal, but is limited by the ACLR and SEM of the bandwidth of the base station, that is, the terminal does not need to perform adjacent channel power suppression according to the frequency range of the channel bandwidth of the terminal, but can perform adjacent channel power suppression according to the frequency range of the bandwidth of the base station. Therefore, it can be understood that the adjacent channel spurious power of the base station caused by the transmission of the terminal in the transmission resource is small, so the terminal does not need to excessively suppress the transmit power, and the transmit power of the terminal can be increased. For example, a reduction value y of MPR can be set on the basis of the MPR value shown in Table 4, the corresponding MPR value is queried according to Table 4, and y dB is reduced from the MPR value as the maximum power backoff value.
[0269] 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, the terminal device can be required to have a left memory effect type, or can not be required to have a memory effect type.
[0270] It can be understood that the terminal device can obtain the operator information through a message sent by the network device. Taking the operator information of the first adjacent channel as an example, the network device can carry the correspondence between the frequency band and the operator information in a broadcast message such as a system information block (SIB), and correspondingly, the terminal device can obtain the correspondence between the frequency band and the operator information by receiving the broadcast message, and further obtain the operator information of the first adjacent channel. For another example, the network device can carry the correspondence between the frequency band and the operator information in terminal device dedicated signaling, and correspondingly, the terminal device can obtain the correspondence between the frequency band and the operator information through the terminal device dedicated signaling, and further obtain the operator information of the first adjacent channel. In addition, the terminal device can also obtain the correspondence between the frequency band and the operator information through predefinition or preconfiguration, and the like.
[0271] Similarly, as shown in FIG. 11, the bandwidth of the base station is 160 MHz, of which 100 MHz with a smaller frequency is configured as the channel bandwidth of the terminal device, and 60 MHz with a larger frequency overlaps with the second adjacent channel of the terminal device. If the transmission resource (represented by a black area in FIG. 11) of the terminal device belongs to the external right resource area, the terminal device can determine the maximum transmission power on the transmission resource according to the operator information of the second adjacent channel. Wherein, the first information can indicate that the power of the terminal device on the second adjacent channel is less than the power of the terminal device on the first adjacent channel, that is, the type of memory effect of the terminal device can be required or can not be required.
[0272] As an example, the value of y and the determination manner of the maximum backoff power information can be added as a new note in Table 4 of the protocol. For example, the following note is added: for the external left RB allocation area, if the adjacent channel on the left side of the channel bandwidth of the terminal device and the channel bandwidth belong to the same operator network, the terminal device determines the maximum transmission power according to y, or the terminal device determines the maximum transmission power according to MPR and y, or the terminal device determines the maximum transmission power according to (MPR-y). Wherein, MPR can be greater than or equal to 1, and y is greater than 0.
[0273] Similarly, the following note can be added: for the external right RB allocation area, if the adjacent channel on the right side of the channel bandwidth of the terminal device and the channel bandwidth belong to the same operator network, the terminal device determines the maximum transmission power according to y, or the terminal device determines the maximum transmission power according to MPR and y, or the terminal device determines the maximum transmission power according to (MPR-y).
[0274] 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. It can also be said that different channel bandwidths can correspond to different maximum power backoff information. For example, different channel bandwidths can correspond to different values of y. For example, the MPR table shown in Table 4 can be added with a note containing the correspondence between the value of y and the channel bandwidth.
[0275] Optionally, the value of y corresponding to the outer left resource region can be the same or different from the value of y corresponding to the outer right resource region, and if different, the value of y corresponding to the outer left resource region and the value of y corresponding to the outer right resource region can be denoted as y1 and y2 respectively.
[0276] It can be understood that the scheme for determining the maximum transmit power of the terminal device according to y can be implemented in combination with the first information or independently of the first information. That is, whether the terminal device transmits the first information or not, as long as the transmission resource of the terminal device belongs to the outer left resource region, the terminal device can determine the maximum transmit power on the transmission resource according to 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 region, the terminal device can determine the maximum transmit power on the transmission resource according to the operator information of the second adjacent channel.
[0277] In a possible embodiment, the terminal device can also reduce the power consumption value when transmitting a signal through the transmission resource. For example, the terminal device can reduce the voltage without changing the transmit power, and reduce the power consumption by reducing the voltage.
[0278] As an example, after the terminal device sends the first information 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 consumption reduction value of the terminal device can be denoted as p Joule per bit (Joule / bit). The value of p can be added as a note in Table 4 of the protocol or in a table related to the transmit power consumption of the terminal device. For example, the following note is added: for the outer RB allocation region, if at least one of the following conditions is met: the terminal device turns on the indication of memory effect type, the terminal device transmits the first information, or the network device determines the transmission resource of the terminal device according to the first information, the terminal device determines the transmit power consumption according to p, for example, the terminal device reduces the transmit power consumption by p Joule per bit.
[0279] Optionally, the power consumption reduction value can correspond to the channel bandwidth or the bandwidth of the network device. Alternatively, different channel bandwidths or bandwidths of the network device can correspond to different power consumption reduction values. For example, different channel bandwidths can correspond to different p values, and when determining the transmission resource according to the first information and the channel bandwidth, the terminal can determine the power consumption according to the power consumption reduction value corresponding to the channel bandwidth. For another example, different bandwidths of the network device can correspond to different p values, and when determining the transmission resource according to the first information and the bandwidth of the network device, the terminal can determine the power consumption when transmitting the signal in the transmission resource according to the power consumption reduction value corresponding to the bandwidth of the network device. For example, the MPR table shown in Table 4 can be added with an annotation, which includes the correspondence between the y value and the channel bandwidth, and / or the correspondence between the y value and the bandwidth of the network device.
[0280] As another example, in the case that the transmission resource of the terminal device belongs to the external left resource region or the external right resource region, the terminal device can determine the transmission power consumption according to the operator information of the first adjacent channel (i.e., the left adjacent channel) or the operator information of the second adjacent channel (i.e., the right adjacent channel). For example, the terminal device can determine the transmission power consumption according to the operator information of the first adjacent channel. In this example, the power consumption reduction value of the terminal device can be denoted as q joules per bit.
[0281] For example, if the transmission resource of the terminal device belongs to the external left resource region, the terminal device can determine the transmission power consumption according to the operator information of the first adjacent channel. For example, if it is determined according to the operator information of the first adjacent channel that the operator of the first adjacent channel is the same as the operator of the channel bandwidth in which the transmission resource of the terminal device is located, the terminal device can determine the transmission power consumption according to q, for example, the terminal device reduces the transmission power consumption by q joules per bit to transmit at a lower power consumption.
[0282] For another example, if the transmission resource of the terminal device belongs to the external right resource region, the terminal device can determine the transmission power consumption according to the operator information of the first adjacent channel. For example, if it is determined according to the operator information of the first adjacent channel that the operator of the second adjacent channel is the same as the operator of the channel bandwidth in which the transmission resource of the terminal device is located, the terminal device can determine the transmission power consumption according to q, for example, the terminal device reduces the transmission power consumption by q joules per bit to transmit at a lower power consumption.
[0283] In the above examples, the value of q can be added as an annotation in Table 4 of the protocol or in a table related to the transmission power consumption of the terminal device.
[0284] Optionally, the power consumption reduction value can be associated with the channel bandwidth or the bandwidth of the network device. Alternatively, different channel bandwidths or bandwidths of the network device can correspond to different power consumption reduction values. For example, different channel bandwidths can correspond to different p values. For example, the MPR table shown in Table 3 can be supplemented with an annotation containing the correspondence between the y value and the channel bandwidth or the bandwidth of the network device.
[0285] Optionally, the q value corresponding to the outer left resource region can be the same as or different from the q value corresponding to the outer right resource region, and if different, the q values corresponding to the outer left resource region and the outer right resource region can be denoted as q1 and q2, respectively.
[0286] In a possible embodiment, the terminal device can further send fourth information. The fourth information is used to indicate the difference between the power of the terminal device on the first adjacent channel and the power of the terminal device on the second adjacent channel (referred to as adjacent channel power difference), or in other words, the fourth information is used to indicate the adjacent channel power difference when the terminal device transmits a signal on the channel bandwidth.
[0287] It can be understood that the adjacent channel power difference 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 adjacent channel ACLR difference).
[0288] Correspondingly, the network device receives the fourth information and determines the scheduling priority of the terminal device according to the fourth information. The scheduling priority is positively correlated with the absolute value of the power difference (or the adjacent channel ACLR difference). The scheduling priority is positively correlated with the priority degree of the network device scheduling the terminal device. That is, the greater the absolute value of the adjacent channel power difference and / or the greater the absolute value of the adjacent channel ACLR difference, the higher the scheduling priority of the terminal device, that is, the network device can preferentially schedule the terminal device. That is, the terminal device can be preferentially allocated transmission resources from the channel bandwidth or the bandwidth of the network device. It can be understood that the greater the absolute value of the adjacent channel power difference and / or the greater the absolute value of the adjacent channel ACLR difference, the greater the benefit of the increase in the transmission power resulting from the allocation of the transmission resources of the terminal device in the manner of the present application.
[0289] As shown in Table 5, the greater the absolute value of the adjacent channel power difference and / or the greater the adjacent channel ACLR difference, the higher the scheduling priority of the corresponding terminal device.
[0290] Table 5
[0291] It can be understood that the fourth information can also indicate the difference level. For example, the difference level represents a level corresponding to the adjacent channel power difference and / or the adjacent channel ACLR difference, and similar differences can be combined into one difference level to reduce the indication overhead.
[0292] As an example, when the adjacent channel power difference is greater than the first threshold and / or the adjacent channel ACLR difference is greater than the 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 that the first threshold is 1, when the adjacent channel power difference is greater than 1, the scheduling priority of the terminal device is higher than 1.
[0293] As another example, when the adjacent channel power difference belongs to the first power range, the scheduling priority of the terminal device is the scheduling priority corresponding to the first power range. In addition, when the adjacent channel power difference belongs to the 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 first 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, and 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.
[0294] Taking Table 5 as an example, if the network device determines that the difference level corresponding to the terminal device #1 is I according to at least one of the adjacent channel power difference, the adjacent channel ACLR difference or the difference level reported by the terminal device #1 through the fourth information, and determines that the difference level corresponding to the terminal device #1 is V according to at least one of the adjacent channel power difference, the adjacent channel ACLR difference or the difference level reported by the terminal device #2 through the fourth information, the network device can preferentially allocate the transmission resource of the terminal device #2 in the same (or overlapping) channel bandwidth range.
