Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a communication method and apparatus. Background Technology

[0002] With the development of user equipment (UE), these devices are running more and more applications, users are spending more and more time on them, and the amount of data accessed is increasing, making power consumption a more prominent issue. In the 4G era, UEs generally required daily charging. With the advent of 5G, due to its higher operating frequency and larger bandwidth, 5G UEs consume significantly more power than 4G UEs. It is estimated that 5G UEs consume twice the power of 4G UEs. Therefore, saving power in UEs has become a pressing problem.

[0003] Currently, access network devices can allocate resources to terminal devices, such as time-domain, frequency-domain, spatial-domain, and code-domain wireless transmission resources. Terminal devices can then use these allocated resources to transmit data. However, when terminal devices use these allocated resources to transmit data, power consumption is wasted, and the issue of saving terminal device power consumption cannot be resolved. Summary of the Invention

[0004] This application provides a communication method and apparatus that can save power consumption of terminal devices.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] Firstly, a communication method is provided. This method may include: acquiring transmission energy efficiency information of a terminal device. The transmission energy efficiency information can be used to determine the resources allocated to the terminal device. Scheduling information is sent to the terminal device. The scheduling information can be used to indicate the resources.

[0007] It should be noted that the aforementioned "resources allocated to the terminal device" can be replaced with "resources allocated to the terminal device." The aforementioned resources allocated to the terminal device may include at least one of: resources scheduled for the terminal device, resources activated for the terminal device, and resources configured for the terminal device. The aforementioned "resources scheduled for the terminal device" may be resources actually used for data transmission and can be replaced with "transmission resources of the terminal device's data channel."

[0008] Based on the communication method provided in the first aspect, the access network device can send scheduling information to the terminal device according to the transmission energy efficiency information provided by the terminal device. In this way, the terminal device can request the access network device to determine the resources allocated to it based on the requested transmission energy efficiency information. For example, the terminal device's transmission energy efficiency information can instruct the access network device to increase the proportion of resources scheduled for the terminal device relative to the activated resources of the terminal device, thereby improving the resource scheduling ratio of the terminal device, saving power consumption, and improving the quality of service for users, including reducing packet transmission latency and / or increasing packet transmission rate.

[0009] It should be noted that the aforementioned "resource scheduling ratio of terminal devices" can be expressed as "utilization rate of resources allocated to terminal devices," "scheduling ratio of terminal devices," or "scheduled ratio of terminal devices." The term "transmission energy efficiency information" in this application is a term defined for convenience. "Transmission energy efficiency information" can be used to determine the resources allocated to terminal devices, but it does not indicate that the effect of this application is only an improvement in transmission energy efficiency, nor does it indicate that this application can only be used to improve transmission energy efficiency. As mentioned above, the effect of this application can also include: improvement in one or more of the following: packet transmission rate, packet transmission latency, etc., resulting in improved user service quality, or improved user experience (QoE). Furthermore, "transmission energy efficiency information" can also be expressed as "resource scheduling rate information," "service level information," etc.

[0010] In one possible design, the aforementioned transmission energy efficiency information may include one or more of the following: desired resource scheduling ratio, the amount of resources the terminal device expects to be scheduled, the amount of resources the terminal device expects to be activated, the amount of resources the terminal device expects to be configured, the desired transmission energy efficiency level of the terminal device, the desired service level of the terminal device, or the desired transmission energy efficiency adjustment amount of the terminal device. The desired resource scheduling ratio can be used to determine: the ratio of the amount of resources scheduled to the terminal device to the amount of resources activated by the terminal device, or the ratio of the amount of resources scheduled to the terminal device to the amount of resources configured by the terminal device. Accordingly, the terminal device's request to the access network device to determine the resources allocated to the terminal device based on the transmission energy efficiency information may include one or more of the following: the resources scheduled to the terminal device, the activated resources, the configured resources, and the resource scheduling ratio. This provides multiple ways for the terminal device to request the access network device to adjust the allocated resources, thereby more flexibly improving the resource scheduling ratio of the terminal device, saving power consumption of the terminal device, and improving user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0011] It should be noted that "the terminal device's desired transmission energy efficiency level" can be expressed as "the terminal device's desired service level" or "the terminal device's desired resource scheduling level." In other words, "resource scheduling level," "service level," and "transmission energy efficiency level" are interchangeable. The term "preferred," "preference," "expected," or "expectation" can be replaced with "target" or "recommended." Similarly, "resource size" can be replaced with "resource dimensions," "resource number," "resource length," or "bandwidth." Taking the representation of resources in the 3rd generation partnership project (3GPP) in the long term evolution (LTE) and new radio (NR) as an example, for frequency domain resources, "resource size" can be expressed as "the number of RBs (resource blocks, RBs)", the transmission resources allocated to terminal devices can be expressed as "the total number of RBs", and the resources activated by the terminal device, such as the size of the bandwidth part (BWP), can also be expressed as "the size of active BWP".

[0142] First, this application provides a brief introduction to the technical terms that may be involved in the embodiments.

[0143] 1. Resources configured on the terminal device

[0144] Access network devices can send higher-layer signaling carrying configuration information, such as RRC layer signaling (i.e., access layer signaling) or non-access layer signaling, to terminal devices. The configuration information can be used to indicate the resources configured for the terminal device.

[0145] For example, the configuration information indicating the resources configured for the terminal device may include two component carriers (CCs): CC1 and CC2, with each carrier configured with four component windows (BWPs). CC1 includes BWP1_1, BWP1_2, BWP1_3, and BWP1_4, while CC2 includes BWP2_1, BWP2_2, BWP2_3, and BWP2_4. Furthermore, the configuration information may indicate the number of MIMO layers for each BWP, for example, indicating that BWP1_1, BWP1_2, BWP1_3, and BWP1_4 are configured with 2, 2, 4, and 4 layers respectively, and indicating that BWP2_1, BWP2_2, BWP2_3, and BWP2_4 are configured with 1, 1, 2, and 2 layers respectively.

[0146] 2. Resources of the terminal device that have been activated.

[0147] Access network devices can send signaling carrying activation information, such as physical layer signaling, MAC layer signaling, or RRC layer signaling, to terminal devices. This activation information can indicate the resources activated for the terminal device. The terminal device's data can be carried within the activated resources.

[0148] It should be noted that the resources activated by the terminal device can be some or all of the resources configured on the terminal device.

[0149] For example, when the terminal device is configured with resources CC1 and CC2 as described above, the resources activated by the terminal device may include activating BWP1_1 in CC1 and BWP2_1 in CC2. In this case, the terminal device's data is carried within BWP1_1 and BWP2_1, but the specific resource(s) within BWP1_1 and BWP2_1 to be carried by the data still needs to be scheduled by the access network equipment.

[0150] 3. Scheduled resources for terminal devices

[0151] Access network devices can send physical layer signaling carrying scheduling information to terminal devices. This scheduling information indicates which resources the terminal device is scheduled to use; that is, the resources scheduled for the terminal device are the resources actually used for data transmission. Data from the terminal device can be transmitted within the scheduled resources, and the transmitted data is carried on data channels. Data channels may include: Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), and Physical Sidelink Shared Channel (PSSCH), etc.

[0152] It should be noted that the resources scheduled for the terminal device can be part or all of the corresponding activated resources for the terminal device, or the resources scheduled for the terminal device can be part or all of the corresponding configured resources for the terminal device.

[0153] For example, when BWP1_2 comprises 273 resource blocks, and the resource activated by the terminal device is BWP1_2, the access network device can schedule the terminal device to transmit M resource blocks from the 273 resource blocks of BWP1_2 using PDSCH, where M is less than or equal to 273. In this case, the data transmitted by the terminal device (i.e., PDSCH) is actually carried on these M resource blocks.

[0154] 4. Resource utilization rate or resource allocation ratio

[0155] Resource utilization or resource scheduling ratio can be the ratio of the actual amount of resources used by the terminal device for data transmission to the amount of resources activated by the terminal device, or the ratio of the actual amount of resources used by the terminal device for data transmission to the amount of resources configured for the terminal device. The configured or activated resource size represents the total available resources of the terminal device. Since the resources actually used for data transmission can be the scheduled resources, resource utilization or resource scheduling ratio can also be expressed as the ratio of the scheduled resources to the activated resources, or the ratio of the scheduled resources to the configured resources, or the ratio of the scheduled resources to the available resources. Therefore, "resource scheduling ratio" and "resource utilization" are interchangeable. Additionally, "resource utilization" can be used interchangeably with "resource efficiency."

[0156] It should be noted that the difference between "resources actually used for data transmission" and "resources activated on the terminal device" is that some resources activated on the terminal device may not be used for data transmission. The difference between "resources actually used for data transmission" and "resources configured on the terminal device" is that some resources configured on the terminal device may not be used for data transmission. The size of the configured resources or the size of the activated resources is the total available resource size of the terminal device. The difference between "resources activated on the terminal device" and "resources configured on the terminal device" is that some resources configured on the terminal device may not be activated. Additionally, configuration and activation may be equivalent, for example, resources configured on the terminal device may also be activated resources.

[0157] It's understandable that when transmitting data, the terminal device determines the amount of computing resources (including hardware and software resources, such as radio frequency, front-end, processor, and memory) used for sending and receiving data based on the size of the activated or configured resources, or the available resources. Therefore, the larger the activated or configured resources, the more computing resources the terminal device uses for sending and receiving data. The activated or configured resources can also be understood as the terminal device's current data processing capacity. The higher the proportion of activated or configured resources used for actual data transmission, the more fully the terminal device utilizes its resources. Therefore, the larger the proportion of resources actually used for data transmission, the less energy is wasted when using activated or configured resources for data transmission, resulting in higher transmission energy efficiency.

[0158] Typically, when an access network device indicates that a specific carrier or a specific BWP is activated, it means that the access network device and the terminal device will transmit data on the activated resource. The terminal device will activate the corresponding hardware and software processing resources according to the size of the activated carrier or BWP resource.

[0159] For example, when the access network device indicates the activation of BWP1_1, and the size of the activated BWP1_1 is 51 RBs with a subcarrier spacing of 30 kHz, it means that data transmission will be carried out within a 20 MHz bandwidth. The terminal device will then activate the corresponding processing resources according to the 20 MHz bandwidth, such as opening a 20 MHz radio frequency channel. If the maximum data transmission rate corresponding to 20 MHz is 460 Mbps, the terminal device will prepare to use a processor capable of handling 460 Mbps for data transmission.

[0160] For example, when a network device instructs the activation of BWP1_2, with a size of 273 RBs and a subcarrier spacing of 30 kHz, it means that data transmission will occur within a 100 MHz bandwidth. The terminal device will then activate the corresponding processing resources according to the 100 MHz bandwidth, such as opening a 100 MHz radio frequency channel. If the maximum data transmission rate corresponding to 100 MHz is 2.3 Gbps, the terminal device will prepare to use a processor capable of handling 2.3 Gbps for data transmission.

[0161] If the terminal device is allocated 51 RBs of resources and uses BWP1_1 as the active BWP (i.e., the active resource size is 51 RBs), then the resource allocation ratio under this assumption (referred to as the first assumption) is 100%. In the second case, if the terminal device is allocated 51 RBs of resources and uses BWP1_2 as the active BWP (i.e., the active resource size is 273 RBs), the resource allocation ratio under this assumption (referred to as the second assumption) is approximately 18.7%. Clearly, the resource allocation ratio under the first assumption is greater than that under the second assumption. The resource allocation ratio here is determined as the ratio of the allocated resource size to the active resource size of the terminal device.

[0162] 5. DRX

[0163] DRX is a working mechanism for terminal devices that can save power. When DRX is configured, the terminal device can operate periodically. In each cycle, the terminal device can enter a "sleep state," such as turning off radio frequency devices and / or the baseband processor, without continuously listening to the physical downlink control channel (PDCCH), thus saving power. The working cycle of the terminal device is called the DRX cycle.

[0164] like Figure 1 As shown, a DRX cycle can include: an on-duration period, an inactivity timer, and an inactivity period (opportunity for DRX), during which the terminal device can sleep.

[0165] During the active period, the terminal device is woken up and continuously listens for the PDCCH. If the terminal device detects a valid PDCCH during the active period, it enters an inactive timer; otherwise, it enters an inactive period. A valid PDCCH here can refer to a channel carrying control signaling sent to the terminal device. The control signaling sent to the terminal device can be dedicated signaling sent to that terminal device, and / or broadcast or multicast signaling sent to all or a group of terminal devices.

[0166] For example, the control channel carrying dedicated signaling transmitted to the terminal device may include: a PDCCH scrambled with the terminal device's cell radio network temporary identifier (C-RNTI); a PDCCH scrambled with the terminal device's modulation and coding scheme radio network temporary identifier (MCS-RNTI); a PDCCH scrambled with the terminal device's configured scheduling radio network temporary identifier (CS-RNTI); a PDCCH scrambled with the terminal device's semi-persistent scheduling cell radio network temporary identifier (SPS-C-RNTI); a PDCCH scrambled with the terminal device's semi-persistent channel state information radio network temporary identifier (SP-CSI-RNTI); a PDCCH scrambled with the terminal device's sidelink radio network temporary identifier (SL-RNTI); and a PDCCH scrambled with the terminal device's sidelink configured scheduling radio network temporary identifier (SideLink Configured RNTI). At least one of the following: a PDCCH scrambled with Scheduling (SL-CS-RNTI) or a PDCCH scrambled with the sidelink LTE-V configured schedul RNTI (SL-L-CS-RNTI) of the terminal device.

[0167] Control channels carrying broadcast or multicast signaling to all or a group of terminal devices may include: PDCCH scrambled with System Information Radio Network Temporary Identifier (SI-RNTI), PDCCH scrambled with Paging Radio Network Temporary Identifier (P-RNTI), PDCCH scrambled with Random Access Radio Network Temporary Identifier (RA-RNTI), PDCCH scrambled with MsgB-RNTI (message B RNTI), PDCCH scrambled with Temporary Cell Radio Network Temporary Identifier (TC-RNTI), PDCCH scrambled with SFI-RNTI (slot format indicator RNTI), PDCCH scrambled with INT-RNTI (interruption RNTI), PDCCH scrambled with TPC-PUSCH-RNTI (transmit power control PUSCH RNTI), and TPC-PUCCH-RNTI (transmit power control PUCCH). PDCCH scrambled with RNTI, PDCCH scrambled with TPC-SRS-RNTI (transmit power control-sounding reference symbols-RNTI), PDCCH scrambled with CI-RNTI (cancellation indication RNTI), PDCCH scrambled with AI-RNTI (availability indicator RNTI), and PDCCH scrambled with PS-RNTI (power saving RNTI).

[0168] It should be noted that the control channel described above is for illustrative purposes only. For specific types of control channels, please refer to the relevant existing technical specifications.

[0169] During the inactivity timer, the terminal device remains in a wake-up state for a period of time, waiting to detect a valid PDCCH again. If no valid PDCCH is detected before the inactivity timer expires, the terminal device returns to the inactive period; otherwise, the terminal device may re-enter the inactivity timer.

[0170] During inactive periods, the terminal device enters sleep mode. Additionally, during active periods, the terminal device can also transmit uplink physical shared channel (PUSCH) data; that is, the active period may also include a PUSCH period (not shown in the diagram).

[0171] In one application scenario, the DRX cycle can include a long DRX cycle (LDRX) and a short DRX cycle (SDRX), and the terminal device can operate according to these two DRX cycles.

[0172] For example, a typical long-short cycle DRX process is as follows: Figure 2 As shown. The switching mechanism between short and long DRX cycles is as follows: If, during a short DRX cycle, the terminal device detects a valid PDCCH before the inactivity timer overflows, and no valid PDCCH is detected within the number of consecutive cycles indicated by the DRXShortCycleTimer, then the terminal device can enter a long DRX cycle after the DRXShortCycleTimer expires. Conversely, if the terminal device successfully decodes the PDCCH during a long DRX cycle, then the terminal device enters a short DRX cycle after the inactivity timer overflows.

[0173] It should be noted that the above description of the DRX working process is illustrative. For specific DRX mechanisms, please refer to the relevant existing technical specifications.

[0174] 6. Data transmission

[0175] Unless otherwise specified, data transmission as described herein includes both sending and receiving data. For example, for access network devices, downlink data transmission refers to the access network device sending PDSCH, and uplink data transmission refers to the access network device receiving PUSCH. For terminal devices, downlink data transmission refers to the terminal device receiving PDSCH, and uplink data transmission refers to the terminal device sending PUSCH.

[0176] In implementing the embodiments of this application, the inventors of this application discovered that:

[0177] When a terminal device transmits data, the resources actually used for data transmission often only account for a portion of the allocated resources. In other words, the resource allocation ratio of the terminal device is not high. This results in some power consumption being wasted when the terminal device uses the allocated resources to transmit data, and the goal of saving terminal power consumption cannot be achieved.

[0178] In particular, a low allocation of resources to terminal devices can reduce the quality of user service (including one or more of packet transmission rate and packet transmission latency), thereby reducing user experience speed, increasing packet transmission latency, and increasing terminal device power consumption.

[0179] In addition, QoS has been introduced to evaluate the service quality of user experience. Specifically, different service levels (QoS) are determined for different data packet service types, and corresponding data packets are transmitted on the corresponding air interface resources according to the requirements of the QoS parameters in order to meet the service level requirements.

[0180] Currently, QoS parameters can include one or more of the following: resource type, such as guaranteed bit rate (GBR), non-guaranteed bit rate (Non-GBR), or delayed critical bit rate (Delay Critical GBR), default priority level, packet delay budget, packet error rate, default maximum data burst volume, and default averaging window.

[0181] For example, Table 1 shows the contents of the 5QI (5G QoS Identifier) ​​in the existing 3GPP TS23.501. Referring to Table 1, a 5QI value can indicate various QoS parameters that a service meets during transmission, including: resource type, default priority value, packet delay margin, packet error rate, default maximum burst size, and default average window.

[0182] For example, taking a video (buffered stream) service based on TCP (Transmission Control Protocol) as an example, a value of 5QI of 6 indicates that the service meets the following requirements during transmission: resource type is Non-GBR, default priority is 60, packet delay margin is 300 milliseconds (ms), and packet error rate is 10%. -6 The default maximum burst packet size is not applicable (N / A), and the default average window is not applicable.

[0183] For example, taking the control plane (IMS Signalling) for management voice services as an example, a value of 5QI indicates that the service meets the following requirements during transmission: resource type is Non-GBR, default priority is 10, packet delay margin is 100 milliseconds, and packet error rate is 10%. -6 The default maximum burst packet size and the default average window are not applicable.

[0184] Table 1

[0185]

[0186] However, existing QoS parameters show that there are currently no parameters to evaluate the utilization rate of air interface data transmission resources. Therefore, terminal devices lack the means to send their desired resource utilization rates to access network devices, and access network devices cannot obtain the desired air interface data transmission resource utilization rates from each terminal device. Consequently, when the resource utilization rate allocated to a terminal device is low and transmission energy efficiency is low, at least some power consumption is wasted when the terminal device uses scheduled resources to transmit data, resulting in persistently high power consumption for the terminal device.

[0187] To address the problem of wasted power consumption during data transmission by terminal devices, embodiments of this application provide a communication method and apparatus to save power consumption and improve user service quality, including reducing packet transmission latency and / or increasing packet transmission rate. It should be noted that the aforementioned deficiencies are the result of careful practical research by the inventors.

[0199] It should be noted that the communication method provided in the embodiments of this application can be applied to... Figure 3 The communication between the terminal equipment, access network equipment and core network equipment shown.

[0200] It should be understood that Figure 3 This is a simplified diagram for ease of understanding only. The communication system may also include other network devices and / or other terminal devices. Figure 3 It was not drawn in the middle.

[0201] First, the communication method provided in this application embodiment is briefly introduced. The method includes: obtaining transmission energy efficiency information of a terminal device, which can be used to determine the resources allocated to the terminal device; and sending scheduling information to the terminal device, which can be used to indicate the resources. Thus, the access network device can send scheduling information to the terminal device based on the transmission energy efficiency information provided by the terminal device, thereby allowing the terminal device to request the access network device to determine the resources allocated to it based on the requested transmission energy efficiency information. For example, the transmission energy efficiency information of the terminal device can instruct the access network device to increase the proportion of scheduled resources to activated resources of the terminal device, thereby improving the resource scheduling ratio of the terminal device, saving power consumption, and improving user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0202] The following will combine Figures 4-6 The communication method provided in the embodiments of this application will be described in detail.

[0203] For example, Figure 4 Flowchart of the communication method provided in the embodiments of this application Figure 1 This communication method can be applied to Figure 3 The communication between the terminal device and the access network device shown.

[0204] like Figure 4 As shown, the communication method may include the following steps:

[0205] S401, the access network device obtains the transmission energy efficiency information of the terminal device.

[0206] The aforementioned transmission energy efficiency information can be used to determine the resources allocated to the terminal device.

[0207] In some possible implementations, the aforementioned transmission energy efficiency information may include one or more of the following: desired resource scheduling ratio, desired resource size for the terminal device to be scheduled, desired resource size for the terminal device to be activated, desired resource size for the terminal device to be configured, desired transmission energy efficiency level for the terminal device, desired service level for the terminal device, or desired transmission energy efficiency adjustment amount for the terminal device. The desired resource scheduling ratio can be used to determine: the ratio of the resource size scheduled by the terminal device to the resource size activated by the terminal device, or the ratio of the resource size scheduled by the terminal device to the resource size configured by the terminal device.

[0208] The following explanation of the various transmission energy efficiency information mentioned above will be provided in conjunction with specific application scenarios.

[0209] Table 2 shows a possible resource utilization scenario for the terminal device. The terminal device is configured with two carriers, CC1 and CC2. Assume CC1 is configured with four BWPs: BWP1_1, BWP1_2, BWP1_3, and BWP1_4, and CC2 is configured with two BWPs: BWP2_1 and BWP2_2.

[0210] According to Table 2, the terminal device is currently configured with 2 carriers (i.e., 273 + 133 = 406 RBs). Both carriers CC1 and CC2 are activated. The activated BWP for carrier CC1 is BWP1_1, and the activated BWP for carrier CC2 is BWP2_2, for a total of 2 activated BWPs (i.e., 273 + 51 = 324 RBs). BWP1_1 has 51 RBs scheduled, so its resource scheduling ratio is 18.6% (51 / 273), and BWP2_2's resource scheduling ratio is 100% (51 / 51). The total resource scheduling ratio for both carriers is 31.1% ((51+51) / (273+51)). The resource scheduling ratio is determined by the ratio of the scheduled resource size to the activated resource size of the terminal device.

[0211] Table 2

[0212]

[0213]

[0214] If the terminal device expects the resource scheduling ratio to increase to 100%, the content of the above-mentioned transmission energy efficiency information can be exemplified as follows:

[0215] The desired resource scheduling ratio can be 100%.

[0216] The terminal device expects the resource size to be scheduled to be: 273 RBs for BWP1_1, or a total resource size of 324 RBs.

[0217] The terminal device expects the following resource size to be activated: CC1 is 51RB, or CC1 is BWP1_4, or the total activated resource size is 102RBs.

[0218] The terminal device expects to be configured with the following resource sizes: CC1 is configured with 51 RBs, or the total configured resource size is 102 RBs.

[0219] The desired transmission energy efficiency level for terminal equipment can be: Level 1;

[0220] The expected transmission energy efficiency adjustment for the terminal equipment can be: an increase of 81.4% for CC1.

[0221] Since the resources activated by the terminal device can be part or all of the resources configured for the terminal device, that is, the size of the activated resources is less than or equal to the size of the configured resources, in the example above, if the terminal device expects the configured resource size of CC1 to be 51RBs, the access network device can deactivate BWP1_1, BWP1_2, and BWP1_3 of the terminal device, so that only BWP1_4 (51RBs) remains in CC1, or reconfigure the size of BWP1_1, BWP1_2, BWP1_3, and BWP1_4 of the terminal device, so that the total configured resource size of BWP1_1, BWP1_2, BWP1_3, and BWP1_4 is less than or equal to 51RBs.

[0222] It is understood that the specific forms of transmitting energy efficiency information can be varied. Terminal devices can request access network devices to change the resources allocated to them by transmitting energy efficiency information, thereby changing the resource scheduling ratio of the terminal devices. This change can include: increasing the resource scheduling ratio, decreasing the resource scheduling ratio, or keeping the resource scheduling ratio unchanged.

[0223] Optionally, the desired transmission energy efficiency level of the aforementioned terminal equipment can correspond to the desired resource scheduling ratio.

[0224] For example, referring to Table 3 below, it is assumed that the transmission energy efficiency level includes three levels: Level 1 (high energy efficiency), Level 2 (medium energy efficiency), and Level 3 (low energy efficiency). Specifically, a transmission energy efficiency level of Level 3 corresponds to a desired resource scheduling ratio greater than or equal to 0% (this can also be considered as the terminal device having no recommended value for transmission energy efficiency); a transmission energy efficiency level of Level 2 corresponds to a desired resource scheduling ratio greater than 50%; and a transmission energy efficiency level of Level 1 corresponds to a desired resource scheduling ratio greater than or equal to 80%.

[0225] Table 3

[0226]

[0227] It's understandable that the lower limit of the expected resource scheduling ratio increases progressively from Level 3 to Level 1, indicating that the terminal devices' requirements for the resource scheduling ratio also increase progressively. Specifically, Level 3 indicates that the terminal devices have no requirements for the resource scheduling ratio, while Level 1 indicates that the terminal devices require a resource scheduling ratio of 80% or higher.

[0228] It should be noted that the expected resource scheduling ratio corresponding to a lower level of transmission energy efficiency may be greater than or equal to the expected resource scheduling ratio corresponding to a higher level of transmission energy efficiency.

[0229] In addition, higher levels of transmission energy efficiency can be described as guaranteed energy (GE), while lower levels can be described as non-guaranteed energy (Non-GE). For example, referring to Table 3, Level 3 transmission energy efficiency can be described as non-guaranteed energy efficiency, and Level 1 transmission energy efficiency can be described as guaranteed energy efficiency.

[0230] Optionally, the service level desired by the aforementioned terminal equipment can correspond to the desired resource scheduling ratio.

[0231] For example, referring to Table 4, the service level desired by the terminal device can correspond to different expected resource allocation ratios. The service level is divided into two tiers: Standard User and Platinum User. The expected resource allocation ratio for Standard User is greater than 0%, while the expected resource allocation ratio for Platinum User is greater than or equal to 80%.

[0232] Table 4

[0233]

[0234] Optionally, the desired transmission energy efficiency adjustment amount for the aforementioned terminal device can be: the rate or amount of change of the desired resource scheduling ratio relative to the current resource scheduling ratio of the terminal device.

[0235] For example, referring to Table 5 below, assume that the current resource scheduling ratio of the terminal device is 25%. If the expected resource scheduling ratio is 30%, the corresponding transmission energy efficiency adjustment is 20% (rate of change) or 5% (amount of change); if the expected resource scheduling ratio is 50%, the corresponding transmission energy efficiency adjustment is 100% (rate of change) or 25% (amount of change); if the expected resource scheduling ratio is 75%, the corresponding transmission energy efficiency adjustment is 200% (rate of change) or 50% (amount of change).

[0236] Table 5

[0237]

[0238] In this way, by sending a resource scheduling ratio to the access network device, the terminal device can request the access network device to change the resources allocated to it. This allows the access network device to modify the resources allocated to the terminal device according to the terminal device's request, thereby improving the resource scheduling ratio. Furthermore, besides sending the resource scheduling ratio, the allocated resources requested by the terminal device can also include: scheduled resources, activated resources, and configured resources. This provides multiple ways for the terminal device to request the access network device to determine the allocated resources based on transmission energy efficiency information, thus more flexibly improving the terminal device's resource scheduling ratio, saving terminal device power consumption, and improving user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0239] It should be noted that the above "preferred, preference, expected, or expectation" can be replaced with "target" or "recommended." Similarly, "resource size" can be replaced with "resource dimensions," "resource number," "resource length," or "bandwidth." For example, taking the representation of resources in the 3G Partnership's Long Term Evolution and New Radio as an example, for frequency domain resources, "resource size" can be expressed as "the number of RBs," the transmission resources allocated to terminal devices can be expressed as "the total number of RBs," and the resources activated by the terminal device, such as the size of the bandwidth portion, can also be expressed as "the size of active BWP."

[0240] It is understood that the aforementioned expected resource scheduling ratio refers to the utilization rate of the resources that the terminal device expects to be allocated. Since "resource scheduling ratio" and "utilization rate of allocated resources" are interchangeable, the aforementioned expected resource scheduling ratio can also be interpreted as the utilization rate of the resources expected to be allocated.

[0241] It is understood that the aforementioned desired transmission energy efficiency level for terminal devices can be used to indicate the proportion of allocated resources that the terminal device actually uses for data transmission. For example, it could be the ratio of the amount of resources scheduled for the terminal device to the amount of resources activated by the terminal device, or the ratio of the amount of resources scheduled for the terminal device to the amount of resources configured for the terminal device. The desired transmission energy efficiency level for a terminal device can also be expressed as the desired service level or the desired resource scheduling level. That is, resource scheduling level, service level, and transmission energy efficiency level are interchangeable.

[0242] It is also understandable that, based on the brief introduction to the technical term "resource scheduling ratio" mentioned above, adjusting the resource scheduling ratio of a terminal device can adjust the size of the resources actually used for data transmission (scheduled resources), and / or the size of the activated resources, and / or the size of the configured resources. For example, when it is necessary to increase the resource scheduling ratio of the terminal device, the size of the scheduled resources can be increased, and / or the size of the activated resources can be decreased, and / or the size of the configured resources can be decreased.

[0243] Access network devices can determine the resources allocated to terminal devices based on the acquired transmission energy efficiency information. In other words, access network devices can determine the resources allocated to terminal devices based on the acquired transmission energy efficiency information. Optionally, this can be achieved in the following ways:

[0244] Method 1: When the transmission energy efficiency information is the desired resource scheduling ratio, the access network device can determine the size of one or more of the resources scheduled, activated, and configured for the terminal device based on this information, so that the actual resource scheduling ratio of the terminal device matches the desired resource scheduling ratio. Here, "matching" can be understood as: the actual resource scheduling ratio of the terminal device can be greater than or equal to (or greater than) the desired resource scheduling ratio, or the difference between the terminal device's resource scheduling ratio and the desired resource scheduling ratio can not exceed a preset value (e.g., 5%). This application embodiment does not limit this.

[0245] On the one hand, the access network equipment can determine, based on the expected resource scheduling ratio, whether the ratio of the resource size scheduled for the terminal device to the resource size activated for the terminal device is greater than or equal to (or greater than) the expected resource scheduling ratio.

[0246] Continuing with Table 2 as an example, in the application scenario shown in Table 2, the terminal device currently has 324 RBs of activated resources, 101 RBs of currently scheduled resources, and the terminal device's desired resource scheduling ratio is 100%. To achieve the above objective, the access network device can increase the amount of resources scheduled for the terminal device, or decrease the amount of resources activated for the terminal device, or both increase and decrease the amount of resources scheduled for the terminal device, so that the terminal device's resource scheduling ratio is 100%.

[0247] For example, the access network device can determine that the resource size scheduled for terminal device BWP1_1 is 273 RBs. In other words, the access network device can determine that the resource size BWP1_1 scheduled to the terminal device is 273 RBs, thus making the ratio of the scheduled resource size to the activated resource size 100%. Alternatively, it can also determine that the resource size activated for the terminal device is 51 RBs, for example, by activating BWP1_4.

[0248] For example, without implementing the technical solution of this application, a possible resource utilization scenario for the terminal device is shown in Table 6. The terminal device is configured with two carriers, CC1 and CC2. Assume CC1 is configured with four BWPs: BWP1_1, BWP1_2, BWP1_3, and BWP1_4, and CC2 is configured with two BWPs: BWP2_1 and BWP2_2. The terminal device's carrier CC1 is activated, while carrier CC2 is not activated. The activated BWP on carrier CC1 is BWP1_2, and the scheduled resource size of BWP1_2 is 30 RBs. In this case, the terminal's resource scheduling ratio is 30 / 96 = 31.2%. The resource scheduling ratio here is determined as the ratio of the scheduled resource size of the terminal device to the activated resource size of the terminal device.

[0249] Table 6

[0250]

[0251] If the terminal device expects a resource scheduling ratio greater than or equal to 50%, in order to achieve the above-mentioned objective, the access network device may increase the amount of resources scheduled for the terminal device, or decrease the amount of resources activated for the terminal device, or both increase the amount of resources scheduled for the terminal device and decrease the amount of resources activated for the terminal device, so that the resource scheduling ratio of the terminal device is greater than or equal to 50%.

[0252] Referring to Table 6, for example, the access network device can determine that the resource size scheduled for the terminal device in BWP1_1 is greater than or equal to 48 RBs. In other words, the access network device can determine that the resource size BWP1_1 scheduled to the terminal device is 48 RBs, thereby making the ratio of the scheduled resource size to the activated resource size greater than or equal to 50%. Alternatively, BWP1_3 can be activated, and the size of BWP1_3 is 48 RBs, while the scheduled resource size is 30 RBs, thereby making the resource scheduling ratio greater than or equal to 50%. Alternatively, BWP1_3 can be activated, reducing the activated resource size of the terminal device to 48 RBs, while also determining that the resource size scheduled for the terminal device is 40 RBs, so that the resource scheduling ratio of the terminal device is greater than or equal to 50%.

[0253] On the other hand, access network equipment can also determine, based on the expected resource scheduling ratio, that the ratio of the resource size scheduled for the terminal device to the resource size configured for the terminal device can be greater than or equal to the expected resource scheduling ratio.

[0254] For example, assuming the terminal device is currently configured with resources as shown in Table 6, and the scheduled resource size is 30 RBs, then the current resource scheduling ratio of the terminal device is 30 / 96 = 31.2% (the ratio of the scheduled resource size to the configured resource size). If the terminal device's desired resource scheduling ratio is 50%, then to achieve the aforementioned other objective, the access network device can increase the scheduled resource size of the terminal device, or decrease the configured resource size, or both increase and decrease the scheduled resource size, so that the terminal device's resource scheduling ratio is ≥50%.

[0255] For example, an access network device can determine that the resource size scheduled for the terminal device is ≥48 RBs, thereby ensuring that the ratio of the scheduled resource size to the configured resource size is ≥50%. Correspondingly, it can also determine that the resource size configured for the terminal device is ≤96 RBs, or determine that the resource size scheduled for the terminal device is ≥48 RBs and the resource size configured for the terminal device is ≤96 RBs.

[0256] If the resources configured on the terminal device are reduced to less than or equal to 96 RBs, the access network device can configure the bandwidth of CC1 to be less than or equal to 96 RBs, or configure the bandwidth of all BWPs of CC1 to be less than 96 RBs, such as adjusting the size of BWP1_2 to 95 RBs.

[0257] Method 2: When the transmission energy efficiency information is the size of the resources that the terminal device expects to be scheduled, the access network device can determine the resources to be scheduled for the terminal device based on this information. For example, the size of the resources scheduled for the terminal device and the size of the resources that the terminal device expects to be scheduled can differ by no more than a preset value (such as 4 RBs), or the size of the resources scheduled for the terminal device is greater than or equal to (or greater than) the size of the resources that the terminal device expects to be scheduled. This application embodiment does not limit this.

[0258] Specifically, the access network device can determine that the resource size scheduled for the terminal device can be greater than or equal to (or greater than) the resource size that the terminal device expects to be scheduled.

[0259] For example, if the terminal device expects to be scheduled with 24 RBs of resources, the access network device can determine that the terminal device is scheduled with ≥24 RBs of resources, or in other words, the access network device can determine that the terminal device is scheduled with ≥24 RBs of resources.

[0260] Method 3: When the transmitted energy efficiency information is the size of the resource that the terminal device expects to be activated, the access network device can determine the resource that the terminal device will activate based on this information. For example, the size of the resource that the terminal device activates and the size of the resource that the terminal device expects to activate can differ by no more than a preset value (such as 8 RBs), or the size of the resource that the terminal device activates is less than or equal to (or less than) the size of the resource that the terminal device expects to activate. This application embodiment does not limit this.

[0261] Specifically, the access network device can determine that the size of the resources to be activated by the terminal device can be less than or equal to (or less than) the size of the resources to be activated by the terminal device, based on the size of the resources that the terminal device expects to be activated.

[0262] For example, if the terminal device expects the activated resource size to be 24 RBs, the access network device can determine that the activated resource size of the terminal device is less than or equal to 24 RBs. In other words, the access network device can determine that the activated resource size of the terminal device is less than or equal to 24 RBs, such as the bandwidth of the activated carrier being less than or equal to 24 RBs, or the bandwidth of the activated BWP being less than or equal to 24 RBs.

[0263] Method 4: When the transmission energy efficiency information is the resource size that the terminal device expects to be configured with, the access network device can determine the resource size that the terminal device is configured with based on this information. For example, the resource size configured with the terminal device and the resource size that the terminal device expects to be configured with can differ by no more than a preset value (such as 16 RBs), or the resource size configured with the terminal device can be less than or equal to (or less than) the resource size that the terminal device expects to be configured with. This application embodiment does not limit this.

[0264] Specifically, the access network device can determine that the resource size configured for the terminal device can be less than or equal to (or less than) the resource size that the terminal device expects to be configured.

[0265] For example, if the terminal device expects to be configured with a resource size of 24 RBs, the access network device can determine that the resource size configured for the terminal device is ≤24 RBs, or in other words, the access network device can determine that the resource size configured for the terminal device is ≤24 RBs.

[0266] It should be noted that as time, services, and operating environments (such as channel environment) change, the actual amount of resources required by the terminal device for data transmission will also change. Therefore, through methods 1 to 4 above, the terminal device can request the access network device to change the allocated resources so that the allocated resources meet the needs of the terminal device. This increases the proportion of resources actually used for data transmission to the allocated resources, improves the resource scheduling ratio of the terminal device, saves power consumption of the terminal device, and improves the quality of user service, including reducing packet transmission latency and / or increasing packet transmission rate.

[0267] It should be understood that, according to methods 1-4 above, based on transmission energy efficiency information, the access network device can determine the resources allocated to the terminal device within a selectable range. That is, the access network device can flexibly adjust the resources allocated to the terminal device within the selectable range based on the current resource allocation status and the remaining unallocated resources. In this way, the access network device can more flexibly adjust the resources allocated to the terminal device, thereby more flexibly improving the resource scheduling ratio of the terminal device, saving power consumption of the terminal device, and improving the quality of user service, including reducing packet transmission latency and / or increasing packet transmission rate.

[0268] Based on methods 1-4 above, it should be understood that the resources allocated to the terminal device determined by the above transmission energy efficiency information may include one or more of the following: resources for which the terminal device is scheduled, resources for which the terminal device is activated, or resources for which the terminal device is configured.

[0269] Furthermore, as can be seen from the above methods 1-4, the embodiments of this application do not limit the type of resources. Therefore, in some possible implementations, the above-mentioned resources may include one or more of the following: frequency domain resources, time domain resources, spatial domain resources, or code domain resources.

[0270] In other words, transmission energy efficiency information can be used to determine one or more of the frequency domain resources, time domain resources, spatial domain resources, or code domain resources allocated to terminal devices. Put simply, access network devices can determine various resource allocations for terminal devices based on transmission energy efficiency information. This allows for multiple ways for terminal devices to request changes in their allocated resources from the access network device, thereby more flexibly improving the resource scheduling ratio of terminal devices, saving power consumption, and enhancing user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0271] Frequency domain resource size can be represented using resource blocks, which are the unit of measurement for frequency domain resource size in resource allocation. For example, a resource block can include a resource element (RE) of one subcarrier, a resource block including resource elements of multiple subcarriers (e.g., 12), a resource block group (RBG) including multiple resource blocks, or a physical RB pair. Alternatively, frequency domain resource size can also be represented in Hertz (Hz), such as L MHz (L > 0), for example, an active resource size of 50 MHz, a scheduled resource size of 20 MHz, etc.

[0272] Furthermore, the access network device determines the number of resource blocks in the activated portion of the bandwidth for the terminal device based on transmission energy efficiency information. The resource size scheduled for the terminal device can be: the number of resource blocks in the activated or configured portion of the bandwidth used for transmitting the terminal device's data channel. The resource size configured for the terminal device can be: the number of resource blocks in the configured portion of the bandwidth for the terminal device.

[0273] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0274] R1 = N scheduledRB / N actRB ;

[0275] Alternatively, the access network equipment can determine the resource scheduling ratio of the frequency domain allocated to the terminal equipment according to the following formula:

[0276] R1 = N scheduledRB / N configRB ;

[0277] Where R1 is the frequency domain resource scheduling ratio allocated to the terminal device, and N scheduledRB N represents the number of resource blocks in the portion of bandwidth where the terminal device is activated or configured that are used to transmit data channels for the terminal device. actRB N represents the number of resource blocks in the portion of bandwidth where the terminal device is activated. configRB This refers to the number of resource blocks within the allocated bandwidth of the terminal device. Accordingly, the terminal device can also use this formula when generating the desired resource scheduling ratio.

[0278] In carrier aggregation (CA) scenarios, the activated resource size for the aforementioned terminal device can be the sum of the number of resource blocks in the activated portion of the bandwidth of each aggregated active carrier. The scheduled resource size for the aforementioned terminal device can be the sum of the number of resource blocks used for transmitting data channels of the terminal device in the activated or configured portion of the bandwidth of each aggregated active carrier.

[0279] Furthermore, when the access network device determines the frequency domain resources and spatial domain resources allocated to the terminal device based on the transmission energy efficiency information, the size of the resources activated for the terminal device can be the product of the number of resource blocks of the activated portion of the bandwidth and the number of MIMO layers of the activated portion of the bandwidth, i.e.: N actRB *N actMIMO Among them, N actRB N can be the number of resource blocks in the activated portion of the bandwidth for the terminal device, which is the bandwidth value of the activated portion of the bandwidth. actMIMO This can be the number of spatial layers corresponding to the portion of bandwidth activated by the terminal device. Specifically, the number of spatial layers corresponding to the portion of bandwidth activated by the terminal device can refer to either the maximum number of MIMO layers activated by the portion of bandwidth activated by the terminal device, or the maximum number of MIMO layers configured for the portion of bandwidth activated by the terminal device.

[0280] The resource size configured for the aforementioned terminal device can be the product of the number of resource blocks of the configured portion of the bandwidth and the number of MIMO layers of the configured portion of the bandwidth, i.e.: N configRB *N configMIMO Among them, N configRB N can be the number of resource blocks in the allocated bandwidth for the terminal device, which is the bandwidth value of the allocated bandwidth. configMIMO This can be the number of spatial layers corresponding to the portion of bandwidth configured for the terminal device. Specifically, the number of spatial layers corresponding to the portion of bandwidth configured for the terminal device can refer to the maximum number of MIMO layers configured for that portion of bandwidth.

[0281] The resource size scheduled for the aforementioned terminal device can be the product of the number of scheduled resource blocks and the number of scheduled MIMO layers, i.e.: N scheduledRB *N scheduledMIMO Among them, N scheduledRB N can be the number of resource blocks in the portion of bandwidth where the terminal device is activated that are used for transmitting data from the terminal device. scheduledMIMO This can be the number of spatial layers corresponding to the resource blocks used for transmitting the terminal device's data channel within the activated bandwidth of the terminal device; that is, the number of MIMO layers used when scheduling the transmission of the aforementioned terminal device data channel. When a data channel carries multiple transport blocks, N... scheduledMIMOIt can be the maximum value among the MIMO layers corresponding to multiple transport blocks on the data channel.

[0282] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the frequency domain resource and spatial domain resource scheduling ratio allocated to the terminal device according to the following formula:

[0283] R2=(N scheduledRB *N scheduledMIMO ) / (N actRB *N actMIMO );

[0284] Alternatively, the access network equipment can determine the frequency domain resource and airspace resource scheduling ratio allocated to the terminal equipment according to the following formula:

[0285] R2=(N scheduledRB *N scheduledMIMO ) / (N configRB *N configMIMO );

[0286] Where R2 represents the ratio of frequency domain resources to spatial domain resources allocated to the terminal device. Accordingly, the terminal device can also use this formula when generating the desired resource allocation ratio.

[0287] If the communication system does not introduce the concept of partial bandwidth, but only the concept of carrier, then the aforementioned partial bandwidth can be replaced by the carrier. That is: N scheduledRB N represents the number of resource blocks in the carriers on which the terminal device is activated or configured, used to transmit the terminal device's data channel. actRB N represents the number of resource blocks in the carrier activated by the terminal device. configRB The number of resource blocks in the carrier configured for the terminal device.

[0288] Furthermore, when the access network device determines the time-domain resources allocated to the terminal device based on transmission energy efficiency information, the amount of resources activated for the terminal device can be: the duration the data channel is open during the DRX cycle of the terminal device. For example, refer to... Figure 2 The duration for which the data channel is open during the DRX cycle is the sum of the duration of the active time period and the total duration of the inactive timer.

[0289] The resource size scheduled for the aforementioned terminal device can be: the transmission duration for data transmission within the terminal device's DRX cycle. For example, refer to... Figure 2 The transmission duration for data transmission in the DRX cycle is the total duration of the PDSCH transmission period and / or the PUSCH transmission period, plus the duration of the PDCCH corresponding to the PDSCH and / or the PUSCH.

[0290] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0291] R3 = t2 / t1;

[0292] Where R3 is the time-domain resource scheduling ratio allocated to the terminal device, t1 is the duration the data channel is open during the DRX cycle of the terminal device, and t2 is the transmission duration used for data transmission during the DRX cycle of the terminal device. Accordingly, the terminal device can also use this formula when generating the desired resource scheduling ratio.

[0293] It is understandable that the amount of resources activated and scheduled for a terminal device can be determined based on a certain time frame, thereby determining the resource scheduling ratio. For example, the duration for data transmission in a terminal device's DRX cycle can be the sum of the data transmission durations in one or more DRX cycles. The duration for opening the data transmission channel in a terminal device's DRX cycle can be the sum of the durations configured to open the data channel in one or more DRX cycles. This "certain time frame" can be pre-agreed according to certain rules, such as pre-agreing to a few seconds or several DRX cycles, or it can be determined by the access network device, the terminal device, or the core network device and then sent to other devices to increase flexibility.

[0294] Furthermore, when the access network device determines the resources allocated to the terminal device based on transmission energy efficiency information, the amount of resources activated for the terminal device can also be the total amount of control channel monitoring time during the DRX cycle of the terminal device. For example, refer to... Figure 2 The total monitoring period is the total number of PDCCH monitoring periods within the active time period. Here, the monitoring period refers to the time during which the terminal device monitors the control channel (e.g., PDCCH) to obtain control signaling.

[0295] The resource size scheduled for the aforementioned terminal device can also be the number of monitoring periods during which a valid control channel is detected in the terminal device's DRX cycle. For example, refer to... Figure 2 The number of monitoring periods during which a valid control channel is detected can be the total number of monitoring periods during which a valid PDCCH is detected. The aforementioned control channel can be a physical downlink control channel. The aforementioned valid control channel can be a channel carrying control signaling sent to the aforementioned terminal devices. The control signaling sent to the aforementioned terminal devices can be dedicated signaling sent to the aforementioned terminal devices, and / or broadcast signaling or multicast signaling sent to all a group of terminal devices.

[0296] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0297] R4 = N MO1 / N MO2 ;

[0298] Where R4 is the resource scheduling ratio of the terminal device, and N MO1 N represents the number of monitoring periods during which a valid control channel is detected in the DRX cycle of the terminal device. MO2 This represents the total control channel monitoring period within the DRX cycle of the terminal device. Accordingly, the terminal device can also use this formula when generating the desired resource scheduling ratio.

[0299] It is understandable that the amount of resources activated and scheduled by a terminal device can be determined based on a certain time frame, thereby determining the resource scheduling ratio. For example, the total control channel monitoring period in a terminal device's DRX cycle can be the total control channel monitoring period for data transmission in one or more DRX cycles of the terminal device. The number of monitoring periods in a terminal device's DRX cycle where a valid control channel is detected can be the number of monitoring periods in one or more DRX cycles of the terminal device where a valid control channel is detected. Here, the "certain time frame" can be pre-agreed according to certain rules, such as pre-agreed as a few seconds or a number of DRX cycles, or it can be determined by the access network device, the terminal device, or the core network device and then sent to other devices to increase flexibility.

[0300] Furthermore, since the number of monitoring periods in the DRX cycle of the terminal device where no valid control channel is detected is: the total number of control channel monitoring periods in the discontinuous reception cycle of the terminal device minus the number of monitoring periods where a valid control channel is detected, the activated resource size of the terminal device can also be: the number of monitoring periods in the DRX cycle of the terminal device where no valid control channel is detected. For example, refer to... Figure 2 The number of monitoring periods during which no valid control channel was detected is the total number of monitoring periods during which the terminal device did not detect a valid PDCCH.

[0301] Here, the effective PDCCH can refer to the channel carrying control signaling sent to the terminal device. This control signaling can be: dedicated signaling sent to that terminal device, and / or broadcast or multicast signaling sent to all or a group of terminal devices. If the effective PDCCH includes PDCCH carrying dedicated signaling sent to the terminal device, the impact of receiving broadcast or multicast messages on the terminal device's scheduling can be disregarded, thus R4 can more accurately reflect the resource scheduling ratio unique to the terminal device. If the effective PDCCH includes both dedicated signaling and multicast / broadcast signaling sent to the terminal device, then R4 can reflect the overall resource scheduling ratio of the terminal device. In practical applications, the type of control signaling carried by the effective PDCCH can be flexibly selected based on the actual situation.

[0302] The aforementioned monitoring period refers to the monitoring period of the terminal device in the dedicated search space, excluding the monitoring period in the public search space. In some application scenarios, the aforementioned monitoring period may also include the monitoring period in the public search space. In practical applications, whether or not the monitoring period includes the monitoring period in the public search space can be flexibly determined based on the actual situation.

[0303] If the valid PDCCH includes a PDCCH carrying dedicated signaling to the terminal device, then preferably, the monitoring period does not include the monitoring period of the common search space. If the valid PDCCH includes both a PDCCH carrying dedicated signaling to the terminal device and a PDCCH carrying multicast / broadcast signaling to the terminal device, then preferably, the monitoring period includes both the monitoring period of the dedicated search space and the monitoring period of the common search space. In this way, R4 can more accurately characterize the resource scheduling ratio of the terminal device.

[0304] Furthermore, when the access network device determines the resources allocated to the terminal device based on transmission energy efficiency information, the amount of resources activated for the terminal device can be the duration for which the data channel is open in the connected state of the terminal device. The amount of resources scheduled for the terminal device can be the transmission duration for data transmission in the connected state of the terminal device.

[0305] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0306] R5 = t3 / t4;

[0307] Where R5 is the resource scheduling ratio of the terminal device, t4 is the duration of the data channel being open in the connected state of the terminal device, and t3 is the transmission duration for data transmission in the connected state of the terminal device. Accordingly, the terminal device can also use this formula to generate the desired resource scheduling ratio.

[0308] Furthermore, when the access network device determines the resources allocated to the terminal device based on transmission energy efficiency information, the amount of resources activated for the aforementioned terminal device can be: the total number of control channel monitoring periods in the connected state of the terminal device, or the number of monitoring periods in the connected state of the terminal device during which no valid control channel was detected. The amount of resources scheduled for the aforementioned terminal device can be: the number of monitoring periods in the connected state of the terminal device during which a valid control channel was detected.

[0309] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0310] R6 = N MO3 / N MO4 ;

[0311] Where R6 is the resource scheduling ratio of the terminal device, and N MO4 N represents the total number of control channel monitoring periods in the connected state of a terminal device, or the number of monitoring periods in the connected state of a terminal device during which no valid control channel was detected. MO3 This refers to the number of monitoring periods during which a valid control channel is detected in the connected state of the terminal device. Accordingly, the terminal device can also use this formula when generating the desired resource scheduling ratio.

[0312] Furthermore, when the access network device determines the resources allocated to the terminal device based on transmission energy efficiency information, the amount of resources activated for the terminal device can also be the sum of the number of time-frequency resources activated by the terminal device within the first time period. Wherein, the sum of the number of time-frequency resources activated by the terminal device within the first time period is... n represents the number of times the frequency domain resources are changed during the first time period, and T represents the number of times the frequency domain resources are activated. ai N represents the activation time of the frequency domain resource activated after the i-th change. actRB,i Let be the size of the frequency domain resources activated after the i-th change.

[0313] Additionally, if the size of the activated BWP remains unchanged during the first time period, the number of activated time-frequency resources can be the product of the size of the activated frequency domain resources and the length of the activated time domain resources. The size of the activated frequency domain resources is the size of the activated BWP of the terminal device, and the length of the activated time domain resources is the duration configured to open the data channel during the DRX cycle of the terminal device.

[0314] The resource size scheduled for the aforementioned terminal devices can also be the sum of the number of time-frequency resources scheduled for the terminal devices within the first time period. Wherein, the sum of the number of time-frequency resources scheduled for the terminal devices within the first time period is... n represents the number of times the frequency domain resources are changed during the first time period, and T represents the number of times the scheduled frequency domain resources are changed.si N represents the activation time of the frequency domain resource after the i-th change. scheduledRB,i Let be the size of the frequency domain resources that are scheduled after the i-th change.

[0315] Furthermore, if the size of the scheduled frequency domain resources remains unchanged within the first time period, the number of scheduled time-frequency resources can be the product of the size of the scheduled frequency domain resources and the length of the corresponding time domain resources. The size of the scheduled frequency domain resources is the number of RBs scheduled for the terminal device, and the length of the scheduled time domain resources is the transmission duration used for data transmission in the DRX cycle of the terminal device.

[0316] The aforementioned time-frequency resources can refer to time-frequency resources of any size, such as one symbol in the time domain, or one subcarrier in the frequency domain, or one resource unit RE of one symbol in the time domain, or one time slot in the time domain, or one resource block RB of 12 subcarriers in the frequency domain, or one time slot in the time domain and a physical resource block of 12 subcarriers in the frequency domain.

[0317] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0318] R7 = k1 / k2;

[0319] Where R7 is the resource scheduling ratio of the terminal device, k2 is the number of time-frequency resources activated by the terminal device in the first time period, and k1 is the number of time-frequency resources scheduled by the terminal device in the first time period. Accordingly, the terminal device can also use this formula when generating the desired resource scheduling ratio.

[0320] It should be noted that the first time period mentioned above can be agreed upon in advance by certain rules, such as agreeing on a number of seconds or DRX cycles in advance, or it can be determined by the access network equipment, terminal equipment, or core network equipment and then sent to other equipment, so as to increase flexibility.

[0321] Furthermore, when the access network device determines the resources allocated to the terminal device based on the transmission energy efficiency information, the amount of resources activated for the terminal device can also be: the number of time-frequency space resources activated for the terminal device in the second time period. The number of activated time-frequency space resources can be the product of the number of activated time-frequency resources and the number of MIMO layers corresponding to the activated time-frequency resources.

[0322] The resource size scheduled for the aforementioned terminal device can also be: the number of time-frequency space resources scheduled for the terminal device in the second time period. The number of scheduled time-frequency space resources can be the product of the number of scheduled time-frequency resources and the number of MIMO layers corresponding to the scheduled time-frequency resources.

[0323] It is understandable that, based on the specific definitions of the resource sizes of each terminal device mentioned above, the access network device can determine the resource scheduling ratio of the terminal device according to the following formula:

[0324] R8 = k3 / k4;

[0325] Where R8 is the resource scheduling ratio of the terminal device, k4 is the number of time-frequency-space resources activated by the terminal device in the second time period, and K3 is the number of time-frequency-space resources scheduled by the terminal device in the second time period. Accordingly, the terminal device can also use this formula when generating the desired resource scheduling ratio.

[0326] Similarly, the second time period mentioned above can also be agreed upon in advance by certain rules, such as agreeing on a number of seconds or DRX cycles in advance, or it can be determined by the access network equipment, terminal equipment, or core network equipment and then sent to other equipment to increase flexibility.

[0327] In some possible implementations, the aforementioned transmission energy efficiency information may further include a desired power consumption-to-data-volume ratio, where the power consumption corresponding to the desired power consumption-to-data-volume ratio may be less than or equal to the power consumption corresponding to the resources currently allocated to the terminal device. Here, the desired power consumption-to-data-volume ratio is the ratio of the power consumption consumed by the terminal device for data transmission to the amount of data transmitted.

[0328] For example, referring to Table 7, assume that the access network device has multiple pre-defined correspondences between power consumption data ratios and configuration sets. Here, the configuration set represents the resource configuration of the terminal device, and the power consumption of the terminal device corresponding to the configuration set is less than or equal to the power consumption data ratio corresponding to that configuration set. For instance, if the access network device obtains an expected power consumption data ratio of 5 joules per bit (J / b), then the access network device can determine the resources allocated to the terminal device based on the corresponding configuration set C1.

[0329] Table 7

[0330]

[0331]

[0332] It should be understood that the terminal device can also send the desired power consumption data ratio to the access network device. The access network device can then allocate resources to the terminal device based on this information, ensuring that the power consumption corresponding to the allocated resources matches the desired power consumption data ratio. This further provides a way for the terminal device to request the access network device to change the allocated resources, thereby more flexibly improving the resource scheduling ratio of the terminal device, saving power consumption, and improving user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0333] It should be noted that Table 7 above is only an example, and the pre-defined correspondence in access network devices in actual applications is not limited to the situation in Table 7 above.

[0334] Optionally, the desired transmission energy efficiency level of the aforementioned terminal device can correspond to the desired power consumption data volume ratio.

[0335] For example, referring to Table 8 below, assume that the transmission energy efficiency level includes three levels: Level 1, Level 2, and Level 3. Specifically, when the expected power consumption to data volume ratio is greater than 1 J / b and less than or equal to 2 J / b, the corresponding transmission energy efficiency level is Level 1; when the expected power consumption to data volume ratio is greater than 2 J / b and less than or equal to 4 J / b, the corresponding transmission energy efficiency level is Level 2; and when the expected power consumption to data volume ratio is greater than 4 J / b and less than or equal to 5 J / b, the corresponding transmission energy efficiency level is Level 3.

[0336] Table 8

[0337] 1＜Y≤2 Level 1 2＜Y≤4 Level 2 4＜Y≤5 Level 3

[0338] Optionally, the desired transmission energy efficiency adjustment amount for the aforementioned terminal device can be: the rate or amount of change of the desired power consumption to data volume ratio relative to the current power consumption to data volume ratio of the terminal device.

[0339] For example, referring to Table 9 below, assume that the current power consumption to data volume ratio of the terminal device is 2 J / b. If the expected power consumption to data volume ratio is 2.5 J / b, the corresponding transmission energy efficiency adjustment is 10% (rate of change) or 0.5 (amount of change); if the expected power consumption to data volume ratio is 3 J / b, the corresponding transmission energy efficiency adjustment is 50% (rate of change) or 1 (amount of change); if the expected power consumption to data volume ratio is 4 J / b, the corresponding transmission energy efficiency adjustment is 100% (rate of change) or 2 (amount of change).

[0340] Table 9

[0341]

[0342] In some possible implementations, the above-mentioned transmission energy efficiency information may include one or more of the following: transmission energy efficiency information of uplink data, transmission energy efficiency information of downlink data, transmission energy efficiency information of services, transmission energy efficiency information of carriers, transmission energy efficiency information of frequency bands, transmission energy efficiency information of frequency band combinations, transmission energy efficiency information of frequency range (FR), transmission energy efficiency information of terminal equipment type, transmission energy efficiency information of applications, transmission energy efficiency information of access networks, transmission energy efficiency information of users, or transmission energy efficiency information of a specified time period, or transmission energy efficiency information of a specified state.

[0343] The uplink data transmission energy efficiency information may include the PUSCH channel transmission energy efficiency information.

[0344] The transmission energy efficiency information of downlink data may include one or more of the following: transmission energy efficiency information of PDSCH, transmission energy efficiency information of dedicated downlink shared channel (such as transmission energy efficiency information of PDSCH scrambled by C-RNTI, transmission energy efficiency information of PDSCH scrambled by CS-RNTI, and transmission energy efficiency information of PDSCH scrambled by MCS-C-RNTI).

[0345] The transmission energy efficiency information for a service can include one or more of the following: transmission energy efficiency information for voice services, transmission energy efficiency information for video services, transmission energy efficiency information for gaming services, transmission energy efficiency information for web data, etc. That is to say, different services can correspond to different transmission energy efficiency information (or service levels). For example, based on Table 1 above, transmission energy efficiency information (energy type) can be added to the 5QI adopted by 5G to indicate the transmission energy efficiency information corresponding to different services. Assuming that the transmission energy efficiency information includes two levels: guaranteed energy efficiency and non-guaranteed energy efficiency, then the 5QI is modified as shown in Table 10. Guaranteed energy efficiency corresponds to high energy efficiency, and non-guaranteed energy efficiency corresponds to no transmission energy efficiency requirements (i.e., low energy efficiency).

[0346] Referring to Table 10, taking real-time voice as an example, a 5QI value of 1 indicates that the service meets the following requirements during transmission: resource type is GBR, default priority is 20, packet delay margin is 100ms, packet error rate is 10⁻², default maximum burst packet size is not applicable, default average window is 2000ms, and transmission energy efficiency information is GE. The transmission energy efficiency information for an application may include one or more of the following: transmission energy efficiency information for video applications (such as TikTok), transmission energy efficiency information for communication chat applications (such as WeChat), or transmission energy efficiency information for navigation applications (such as Amap), etc.

[0347] Table 10

[0348]

[0349] The transmission energy efficiency information of a carrier may include: the transmission energy efficiency information per carrier, such as the transmission energy efficiency information of carrier 1 and the transmission energy efficiency information of carrier 2.

[0350] The transmission energy efficiency information of a frequency band may include: transmission energy efficiency information per band, such as the transmission energy efficiency information of band 1 or band 40.

[0351] Transmission efficiency information for a frequency range (FR) may include transmission efficiency information per FR, such as transmission efficiency information for FR1, transmission efficiency information for FR2, or transmission efficiency information for FR3.

[0352] The transmission energy efficiency information of a band combination can include: the transmission energy efficiency information per band combination, or the transmission energy efficiency information per band per band combination. For example, the transmission energy efficiency information of band combination 1, or the transmission energy efficiency information of band combination 2, or the transmission energy efficiency of band 1 in band combination 1, or the transmission energy efficiency of band 2 in band combination 1.

[0353] Transmission energy efficiency information for terminal device types may include one or more of the following: transmission energy efficiency information for mobile broadband access terminals (MBB), transmission energy efficiency information for ultra-reliable low latency communication (URLLC) terminals, transmission energy efficiency information for massive IoT terminals, transmission energy efficiency information for vehicle terminals, transmission energy efficiency information for AR / VR type terminals, or transmission energy efficiency information for REDucable CAPability (REDCAP) terminals, etc.

[0354] The transmission energy efficiency information of the access network may include one or more of the following: transmission energy efficiency information of 2G system, or transmission energy efficiency information of 3G system, or transmission energy efficiency information of LTE system, or transmission energy efficiency information of NR system, or transmission energy efficiency of 6G system, etc.

[0355] The user's transmission energy efficiency information may include one or more of the following: transmission energy efficiency information of high-end users, transmission energy efficiency information of mid-range users, or transmission energy efficiency information of low-end users.

[0356] The energy efficiency information transmitted by the terminal device can be energy efficiency information applicable to all situations of the terminal device (per UE).

[0357] The transmission energy efficiency information for a specified state may include one or more of the following: transmission energy efficiency information when the terminal is in an overheated state, or transmission energy efficiency information when the terminal has low battery, transmission energy efficiency when the terminal is in an idle state, transmission energy efficiency when the terminal device is in an inactive state, or transmission energy efficiency when the terminal device is in a connected state.

[0358] It should be noted that when a terminal device sends uplink data transmission energy efficiency information to an access network device, the access network device can allocate resources for the terminal device's uplink data based on the uplink data transmission energy efficiency. It can be understood that other types of transmission energy efficiency information can be understood in the same way, and will not be elaborated upon here.

[0359] It should be understood that when the access network device receives the various transmission energy efficiency information mentioned above, it can determine the allocated resources for the terminal device's uplink data, downlink data, service, carrier, frequency band, frequency band combination, frequency range, application, terminal type, access network, or specified time period. Furthermore, the access network device can allocate resources for different types of terminal devices. This allows for various methods of terminal devices requesting the access network device to change the allocated resources, thereby more flexibly improving the resource scheduling ratio of terminal devices, saving power consumption, and improving user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0360] It should be noted that the above descriptions of various types of energy efficiency information transmission are only feasible examples, and the specific types of energy efficiency information transmitted in actual applications are not limited to those described above.

[0361] In some possible implementations, the aforementioned transmission energy efficiency information may be included in one or more of the following: QoS parameter information, PDU session-related signaling, terminal assistance information, non-access stratum signaling, user subscription information, UE capability information, RRC layer information, media access stratum information, or physical layer signaling.

[0362] For example, as shown in Table 10, the aforementioned transmission energy efficiency requirements can be included in the parameters corresponding to 5QI or QCI (QoS classidentifier) ​​that indicate QoS parameter information.

[0363] It should be noted that the terminal device may execute S501 as appropriate. For example, during the establishment of a PDU session, the terminal device may execute S501, sending transmission energy efficiency information along with the 5QI value in the PDU Session establishment information to the access network device and / or core network device. In this way, when allocating resources to the terminal device, the access network can allocate resources according to this energy efficiency information, ensuring the quality of service of the terminal device. As another example, when overheating occurs, the terminal device may execute the above S501, sending transmission energy efficiency information through terminal auxiliary information to request the access network device to increase the resource scheduling ratio, thereby reducing the terminal device's energy consumption.

[0364] It should be noted that the phrase "resources allocated to the terminal device" can be replaced with "resources allocated to the terminal device." In other words, the aforementioned transmission energy efficiency information can also be used to determine the resources allocated to the terminal device.

[0365] In some possible implementations, the method of obtaining the transmission energy efficiency information of the terminal device described above may include: obtaining the transmission energy efficiency information of the terminal device from the terminal device or the core network device. The method of obtaining the transmission energy efficiency information of the terminal device from the terminal device or the core network device can be referred to in S501 and S601 below, and will not be elaborated upon here.

[0366] It should be understood that by obtaining the transmission energy efficiency information of the terminal device from the terminal device or the core network device, even if the access network device does not parse the transmission energy efficiency information received from the terminal device but forwards it to the core network device, or if the access network device does not receive the transmission energy efficiency information from the terminal device, the information can still be sent back to the access network device by the core network device, thereby enabling the access network device to effectively obtain the transmission energy efficiency information.

[0367] S402, the access network device sends scheduling information to the terminal device, and the terminal device receives the scheduling information from the access network device.

[0368] In this application, the access network device can send scheduling information to the terminal device through the air interface between the access network device and the terminal device. It can be understood that this application does not limit the interaction method between the access network device and the terminal device.

[0369] It is understandable that before sending scheduling information to terminal devices, access network devices can determine scheduling information based on transmission energy efficiency information. The method for determining scheduling information based on transmission energy efficiency information can be found in S502, and will not be elaborated upon here.

[0370] based on Figure 4 The method shown allows the access network device to send scheduling information to the terminal device based on the transmission energy efficiency information provided by the terminal device. In this way, the terminal device can request the access network device to determine the allocated resources based on the transmission energy efficiency information, thereby increasing the proportion of allocated resources actually used for data transmission. This improves the terminal device's resource scheduling ratio, saves power consumption, and enhances user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0371] above Figure 4 The method shown describes how access network devices can send scheduling information to terminal devices based on the transmission energy efficiency information provided by the terminal devices. Please refer to the following... Figure 5 and Figure 6 This section details the specific implementation methods by which access network devices obtain transmission energy efficiency information from terminal devices.

[0372] Figure 5 Flowchart of the communication method provided for embodiments of this application Figure 2 This communication method can be applied to Figure 3 The communication between the terminal device and the access network device is shown. For example... Figure 5 As shown, the communication method may include the following steps:

[0373] S501, the terminal device sends transmission energy efficiency information to the access network device, and the access network device receives the transmission energy efficiency information from the terminal device.

[0374] For example, access network devices can receive transmission energy efficiency information from terminal devices through air interface transmission with terminal devices.

[0375] The transmission energy efficiency information may include one or more of the following: QoS parameter information, PDU session (PDUSession) related signaling, terminal assistance information, non-access stratum signaling, user subscription information, UE capability information, RRC layer information, media access stratum information, or physical layer signaling.

[0376] In this way, access network devices can obtain transmission energy efficiency information from one or more of the following: QoS parameter information, signaling included in the PDU session, terminal assistance information, non-access stratum signaling, user subscription information, UE capability information, RRC layer information, media access stratum information, or physical layer signaling.

[0377] For example, as shown in Table 10, the QoS parameters of the terminal device include transmission energy efficiency information. QoS parameters are indexed by 5QI or QCI. When the PDU session is established, the terminal device indicates the transmission energy efficiency information using 5QI or QCI. Another example is that the terminal device sends transmission energy efficiency information in the UE capability information when accessing the network. Yet another example is that the terminal device can send transmission energy efficiency information in the UE auxiliary information when power saving is needed, such as when the terminal device is in an overheated state. Yet another example is that when power saving is needed, the terminal device transmits energy efficiency information through physical layer signaling so that the transmission energy efficiency information can be quickly obtained by the access network device and thus take effect quickly.

[0378] It is understood that this application does not limit the data transmission method between access network equipment and terminal equipment, or between access network equipment and core network equipment.

[0379] In some possible implementations, the transmission energy efficiency information can be determined before the terminal device sends the transmission energy efficiency information to the access network device.

[0380] The method by which terminal equipment determines transmission energy efficiency information may include: determining transmission energy efficiency information based on one or more of the following: terminal equipment type, terminal equipment operating status, terminal equipment user subscription information, terminal equipment service, access network type, services applicable to terminal users, transmission carrier, transmission frequency band, transmission frequency band combination, transmission frequency range, and transmission link type (including downlink, uplink, or sidelink).

[0381] The types of terminal devices mentioned above may include one or more of the following: wireless broadband access terminals, low-latency high-reliability terminals, massive IoT terminals, vehicle-mounted terminals, or low-capability terminals. For example, when the terminal device is a massive IoT terminal or a low-capability terminal, the expected transmission energy efficiency level of the terminal device is determined to be Level 1; when the terminal device is a vehicle-mounted terminal or a low-latency high-reliability terminal, the expected transmission energy efficiency level of the terminal device is determined to be Level 3.

[0382] The operating status of the aforementioned terminal device may include one or more of the following: remaining battery power, battery temperature, or power supply status (e.g., whether it is connected to an external power source or whether it is battery powered). For example, if the remaining battery power of the terminal device is less than 20%, the expected transmission energy efficiency level of the terminal device is determined to be Level 1; if the remaining battery power of the terminal device is greater than 80%, the expected transmission energy efficiency level of the terminal device is determined to be Level 3. Alternatively, if the battery temperature of the terminal device is greater than 60°C, the expected transmission energy efficiency level of the terminal device is determined to be Level 1; if the battery temperature of the terminal device is less than 30°C, the expected transmission energy efficiency level of the terminal device is determined to be Level 3. Alternatively, if the terminal device is connected to an external power source, the expected transmission energy efficiency level of the terminal device is determined to be Level 3; if the terminal device is battery powered, the expected transmission energy efficiency level of the terminal device is determined to be Level 1.

[0383] The operating states of the aforementioned terminal devices may also include one or more of the following: idle state, inactive state, and connected state. For example, if the terminal device is in the connected state, the desired transmission energy efficiency level is determined to be high energy efficiency (i.e., high transmission energy efficiency). If the terminal device is in the inactive state, the desired transmission energy efficiency level is determined to be low energy efficiency (i.e., transmission energy efficiency is not limited).

[0384] The user subscription information for the aforementioned terminal device can be the user's service plan. For example, referring to Table 11 below, assume the user's service plan includes three plans: A, B, and C. Specifically, when the user uses plan A, the terminal device determines the expected resource allocation ratio can be any value; when the user uses plan B, the terminal device determines the expected resource allocation ratio to be greater than or equal to 50%; and when the user uses plan C, the terminal device determines the expected resource allocation ratio to be greater than or equal to 75%.

[0385] Table 11

[0386] A Unrestricted B Greater than or equal to 50% C Greater than or equal to 75%

[0387] The services offered by the aforementioned terminal devices may include one or more of the following: voice services, video services, or gaming services, etc. Service types can be indicated using 5QI (applicable to 5G systems) or QCI (applicable to 4G systems). Services with the same 5QI or QCI can be grouped into one service category. The terminal device can determine transmission energy efficiency information based on the services offered. For example, the terminal device can determine that high-priority services have higher transmission energy efficiency, and low-priority services have lower transmission energy efficiency. As another example, the terminal device can determine that voice services have higher transmission energy efficiency and gaming services have lower transmission energy efficiency. The terminal device can also determine transmission energy efficiency information based on the established PDU session; for example, services within the same PDU session have the same transmission energy efficiency information.

[0388] The aforementioned access network types may include one or more of the following: 3G network, 4G network, 5G network, or 6G network. For example, when the access network type is a 3G network, the expected scheduling ratio is determined to be 50%; when the access network type is a 4G network, the expected scheduling ratio is determined to be 80%; and when the access network type is a 5G network, the expected scheduling ratio is determined to be 90%.

[0389] The services applicable to the aforementioned end users may include one or more of the following: navigation applications, WeChat applications, or video applications, etc. For example, when the service applicable to the end user is a navigation application, the expected transmission energy efficiency level of the terminal device is determined to be high energy efficiency (i.e., transmission energy efficiency is high); otherwise, the expected transmission energy efficiency level of the terminal device is determined to be low energy efficiency (i.e., transmission energy efficiency is not limited).

[0390] Terminal devices can also determine transmission energy efficiency information based on one or more of the currently configured carrier, frequency band, frequency band combination, and frequency range. For example, if the currently configured carrier is a single carrier, the terminal device's desired transmission energy efficiency level is determined to be low energy efficiency (i.e., transmission energy efficiency is unrestricted); if the currently configured carrier is multiple carriers, the terminal device's desired transmission energy efficiency level is determined to be high energy efficiency (i.e., transmission energy efficiency is high). As another example, the terminal device's desired transmission energy efficiency level corresponding to a carrier in frequency range 1 is determined to be low energy efficiency, or the terminal device's desired transmission energy efficiency level corresponding to a carrier in frequency range 2 is determined to be high energy efficiency.

[0391] Terminal devices can also determine transmission energy efficiency based on the type of transmission link. For example, they can determine that the expected resource scheduling ratio for the downlink is 100%, or that the expected resource scheduling ratio for the uplink is 50%.

[0392] Furthermore, the terminal device can also determine the desired resource scheduling ratio based on the current resource scheduling ratio. For example, the terminal device can calculate a first average size of activated resources and a second average size of scheduled resources within a 5-minute period, then determine the ratio of the first average to the second average as the terminal device's current resource scheduling ratio. Finally, based on the current resource scheduling ratio and reference information (terminal device type, terminal device operating status, terminal device user subscription information, terminal device services, etc.), the desired resource scheduling ratio is determined. In other words, when generating transmission energy efficiency information, the terminal device can determine the desired resource scheduling ratio by calculating the average size of allocated resources over a given time period.

[0393] Accordingly, the aforementioned statistical time period can be determined by the terminal equipment, access network equipment, and core network equipment through predefined rules or through negotiation.

[0394] S502, the access network equipment determines the scheduling information based on the transmission energy efficiency information.

[0395] The scheduling information can be used to indicate the resources allocated to the terminal device. This includes one or more of the scheduled resources, activated resources, and configured resources. These resources include one or more of frequency domain resources, time domain resources, spatial domain resources, or code domain resources. Transmission energy efficiency information can be used to determine one or more of the frequency domain resources, time domain resources, spatial domain resources, or code domain resources allocated to the terminal device. In other words, the access network device can determine various allocated resources for the terminal device based on the transmission energy efficiency information. This allows for multiple ways for terminal devices to request the access network device to change their allocated resources, thereby more flexibly improving the resource scheduling ratio of the terminal devices, saving power consumption, and improving user service quality, including reducing packet transmission latency and / or increasing packet transmission rate.

[0396] Scheduling information can be various signaling messages used by access network devices during the resource allocation process for terminal devices, and can also be used to indicate the resources determined by transmitting energy efficiency information. Examples include downlink control signaling or uplink control signaling carried in the PDCCH.

[0397] The access network device determines scheduling information based on transmission energy efficiency information. One specific implementation method includes: the access network device determining at least one of the following: the size of resources to be scheduled, the size of resources to be activated, and the size of resources to be configured for the terminal device, based on the transmission energy efficiency information. For specific implementation methods, refer to the various methods included in S401, "determining the resources allocated to the terminal device based on transmission energy efficiency information".

[0398] For example, continuing with Table 6, taking frequency domain resources as an example, if the desired resource scheduling ratio is 50%, and the current resource scheduling ratio of the terminal device is 31%, then in order to ensure that the terminal device's resource scheduling ratio is greater than or equal to the desired resource scheduling ratio, the access network device can determine that the resource size scheduled for the terminal device is 48 RBs and generate corresponding scheduling information, which is the frequency domain resource size of the data channel. As another example, taking spatial domain resources and transmission energy efficiency information as the desired activated resource size, if the desired activated resource size is 2 (i.e., the desired number of activated MIMO layers is 2), and the terminal device's current activated resource size is 4 (i.e., the current number of activated MIMO layers is 4), then the access network device can determine that the activated resource size is 2, that is, determine that the current BWP layer number is 2, and generate corresponding scheduling information, which is the number of MIMO layers configured for the BWP.

[0399] For example, consider time-domain resources. If the desired resource scheduling ratio is 50%, that is, the desired time-domain resource scheduling ratio is 50%, and the current time-domain resource scheduling ratio is 25%, then the access network device can adjust the DRX parameters according to the above formula R3 = t2 / t1. For example, it can reduce the duration of the on-duration timer, reduce the duration of the in-activity timer, and increase the DRX period length, thereby achieving a time-domain resource scheduling ratio greater than or equal to 50% and generating corresponding scheduling information, which is the DRX configuration parameter.

[0400] S503, the access network device sends scheduling information to the terminal device, and the terminal device receives the scheduling information from the access network device.

[0401] In some possible implementations, access network devices can also obtain transmission energy efficiency information through core network devices. Specifically, please refer to... Figure 6 This communication method can be applied to Figure 3 The communication between the terminal equipment, access network equipment, and core network equipment shown. For example... Figure 6 As shown, the communication method includes the following steps:

[0402] S601, the terminal device sends transmission energy efficiency information to the core network device, and the core network device receives the transmission energy efficiency information from the terminal device.

[0403] For example, during the establishment of a PDU Session, the terminal device can send transmission energy efficiency information to the core network device through the corresponding interface between the terminal device and the core network device by instructing 5QI or QCI via QoS parameters.

[0404] In addition, terminal equipment can also send user subscription information to core network equipment.

[0405] S602, the core network equipment determines the transmission energy efficiency information of the terminal equipment.

[0406] Optionally, the core network equipment's determination of the terminal equipment's transmission energy efficiency information may include one or more of the following implementation methods:

[0407] Method 1: Receive energy efficiency information transmitted from the terminal device.

[0408] Method 2: Determine transmission energy efficiency information based on the subscription information of the terminal device. For example, the correspondence between subscription information and expected resource scheduling ratio shown in Table 11 above can be used to determine transmission energy efficiency information. Specific implementation details can be found in the description of Table 11, and will not be repeated here.

[0409] It should be noted that method 1 can be executed before method 2, after method 2, or separately. This application embodiment does not limit this.

[0410] Optionally, core network equipment can also obtain the transmission energy efficiency information of terminal equipment directly from its own user subscription information database without going through S601.

[0411] S603, the core network equipment sends transmission energy efficiency information to the access network equipment, and the access network equipment receives the transmission energy efficiency information from the core network equipment.

[0412] It is understood that, based on the above S601 and S603, the access network device can receive transmission energy efficiency information from the terminal device or from the core network device. In other words, the access network device can obtain the transmission energy efficiency information of the terminal device. Therefore, in some possible implementations, obtaining the transmission energy efficiency information of the terminal device may include: obtaining the transmission energy efficiency information of the terminal device from the terminal device or the core network device.

[0413] It should be understood that in S602 mode 1, when the core network receives the transmission energy efficiency information from the terminal device, since the transmission energy efficiency information can be carried in non-access stratum signaling, the access network device cannot directly obtain the transmission energy efficiency of the terminal device from the non-access stratum signaling. Therefore, through the above-mentioned S603, the situation where the access network device cannot obtain the transmission energy efficiency information can be avoided. In addition, the core network device can also determine the transmission energy efficiency information of the terminal device based on the terminal device's subscription information, i.e., the above-mentioned S602 mode 2, and send the transmission energy efficiency information to the access network device accordingly to determine the resources allocated to the terminal device.

[0414] S604, the access network equipment determines the scheduling information based on the transmission energy efficiency information.

[0415] It is understandable that S604 can refer to S502 above, and will not be repeated here.

[0416] S605, the access network device sends scheduling information to the terminal device, and the terminal device receives the scheduling information from the access network device.

[0417] It is understandable that S605 can refer to S503 above, and will not be repeated here.

[0418] In some possible implementations, after receiving scheduling information from the access network device, the terminal device can use the resources indicated by the scheduling information, thereby enabling the terminal device to request the access network device to determine the resources allocated to the terminal device based on transmission energy efficiency information, so as to increase the proportion of resources actually used for data transmission to the allocated resources.

[0419] based on Figure 6 The method shown allows the access network device to effectively obtain transmission energy efficiency information even if it does not parse the transmission energy efficiency information received from the terminal device but forwards it to the core network device, or if the access network device does not receive the transmission energy efficiency information from the terminal device.

This application does not limit it in this respect.

[0432] Furthermore, the technical effects of the communication device 700 can be referenced in the following section. Figures 4-6 The technical effects of any of the communication methods shown in the examples are not elaborated here.

[0433] For example, Figure 8 This is a schematic diagram of the structure of the communication device provided in the embodiments of this application. Figure 2 .like Figure 8 As shown, the communication device 800 includes a processing module 801 and a transceiver module 802.

[0435] Specifically, the transceiver module 802 is used to implement the transceiver functions of the core network equipment, such as executing S601, S603, etc.

[0436] The processing module 801 can be used to process data related to the transmission of energy efficiency information, such as executing S602 as described above. For specific implementation details of the processing module 801 and the transceiver module 802, please refer to the above.

The transmitting module implements the transmitting function of the communication device 800, and the receiving module implements the receiving function of the communication device 800.

[0438] Optionally, the communication device 800 may also include a storage module. Figure 8 (Not shown in the image), the storage module stores programs or instructions. When the processing module 801 executes the program or instructions, the communication device 800 can perform the functions of the core network device in any of the communication methods shown in 7.

[0440] It should be noted that the communication device 800 may be a core network device, or a chip (system) or other component or assembly that can be set in the core network device, or a device that includes the core network device. This application does not limit this.

[0441] In addition, the technical effects of the communication device 800 can be referenced. Figure 6 The technical effects of any of the communication methods shown in the examples are not elaborated here.

[0442] For example, Figure 9 Schematic diagram of the communication device provided in the embodiments of this application Figure 3 The communication device can be a terminal device, access network device, or core network device, or it can be a chip (system) or other component or assembly that can be installed in the terminal device, access network device, or core network device. For example... Figure 9 As shown, the communication device 900 may include a processor 901. Optionally, the communication device 900 may also include a memory 902 and / or a transceiver 903. The processor 901 is coupled to the memory 902 and the transceiver 903, for example, they can be connected via a communication bus.

[0443] The following is combined with Figure 9 A detailed description of each component of the communication device 900 is provided below:

For example, the processor 901 can be one or more central processing units (CPUs), application-specific integrated circuits (ASICs), or one or more integrated circuits configured to implement the embodiments of this application, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).
