Description

Technical Field

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

[0002] Currently, 5G communication networks have standardized many energy-saving features. In the future, the application scenarios and demands of communication technologies will become more complex. These complex scenarios and demands will lead to increased power consumption in products, posing a greater challenge to energy conservation. For base stations, high power consumption will increase operating costs; for terminals, with limited increases in size, area, and battery capacity, high power consumption and heat dissipation present even greater challenges.

[0003] Therefore, how to reduce power consumption is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a communication method and apparatus to reduce power consumption.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] Firstly, a communication method is provided, which is applied to a first device or a device within the first device to communicate with a second device. Optionally, the method can be executed by the first device or by a device within the first device. The first device may be, for example, the first device itself or a logical node, logical module, or software capable of implementing all or part of the functions of the first device. The device within the first device may be, for example, a module within the first device (e.g., a processor, a chip, or a chip system). The first device can be a terminal device or a network device. The following description uses the first device as an example.

[0007] The method includes: acquiring first information, the first information being used to determine a first resource; within the first resource: not needing to receive or not expecting to receive at least one of the following from the second device: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI, or not needing to receive or not expecting to receive; and / or not sending or not expecting to send to the second device at least one of the following: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI, or not sending or not expecting to send. For example, the data may be a data packet carrying signaling and / or data in a higher layer, or the data may be information carried in the physical layer on a data channel or shared channel, such as a transport block (TB). For example, within the first resource, not needing to receive or not expecting to receive can be understood as the first device not receiving any signals; on the other hand, it can be understood as the first device entering sleep mode, including deep sleep, light sleep, micro-sleep, etc. Within the first resource, not sending or not expecting to send can be understood as the first device not sending any signals; on the other hand, it can be understood as the first device going into sleep, including deep sleep, light sleep, microsleep, etc.

[0008] As can be seen from the method described in the first aspect, the first device and the second device align the first resource and the signal transmission / reception or sleep status within the first resource using the first information. The first device and / or the second device can reduce power consumption by eliminating the aforementioned signal reception and / or transmission within the first resource. For example, if the first device can receive no signals related to the second device within the first resource, and correspondingly, the second device can transmit no signals related to the first device within the first resource, then the first device can reduce the power consumption for maintaining reception, and the second device can reduce the power consumption for transmitting. Furthermore, the first device can also reduce the power consumption for both receiving and transmitting based on its own signal transmission situation. If the first device can transmit no signals related to the second device within the first resource, and correspondingly, the second device can receive no signals related to the first device within the first resource, then the first device can reduce the power consumption for transmitting, and the second device can also reduce the power consumption for maintaining reception. Furthermore, the second device can also reduce the power consumption for both receiving and transmitting based on its own signal transmission situation. If the first device can both receive and transmit no signals related to the second device within the first resource, and correspondingly, the second device can both receive and transmit no signals related to the first device within the first resource, then the first device can reduce the power consumption for maintaining both receiving and transmitting, and the second device can also achieve better energy-saving effects at both ends by reducing the power consumption for receiving and transmitting.

[0009] It is understood that obtaining the first information in the above method can be receiving first information, obtaining first information predefined by the protocol, or obtaining pre-configured first information. Optionally, the first resource can also be replaced by a first timer and / or a first time window. The following explanation uses the first resource as an example.

[0010] In one possible design, the requirement not to receive or not expect to receive data from the second device includes: not receiving or not expecting to receive at least one of the following: a first channel and a second channel, wherein the first channel is used to carry data and the second channel is used to carry control information.

[0011] In this design, the second device acts as a data transmitter, capable of transmitting data via the first channel and / or the second channel. Specifically, "not needing to receive or not expecting to receive data from the second device" can mean not receiving data via the first channel and / or the second channel.

[0012] In one possible design, the control information carried by the second channel is used to: instruct the first device to receive or send data, and / or, instruct the second device to send data to the first device.

[0013] In this design, the second device, acting as a data transmitter, can first send control information for scheduling data through the channel carrying control information. In this way, the first device, acting as a receiver, can receive the channel carrying data based on the control information. The data transmitter can also indicate to the receiver that there is data to be sent through the channel carrying control information.

[0014] In one possible design, the first channel is a periodic and / or semi-static configuration and / or an aperiodic channel.

[0015] In one possible design, the first channel includes a periodically and / or semi-statically configured channel.

[0016] In this design, the second device, acting as a data transmitter, can transmit data using multiple pre-configured resources or periodic resources. Therefore, it is not necessary to receive or expect to receive data from the second device. Specifically, this may include not receiving data from a periodically and / or semi-statically configured first channel.

[0017] In one possible design, the step of not sending or not expecting to send data to the second device includes: not sending or not expecting to send at least one of the following: a third channel and a fourth channel, wherein the third channel is used to carry data and the fourth channel is used to carry control information.

[0018] In this design, the first device acts as the data transmitter and can transmit data via the third and / or fourth channels. Specifically, not sending data to the second device or not expecting to send data to the second device can mean not sending data via the third and / or fourth channels.

[0019] In one possible design, the control information carried by the fourth channel is used to: instruct the second device to receive or send data, and / or, instruct the first device to send data to the second device.

[0020] In this design, the first device, acting as a data transmitter, can first send control information for scheduling data through a channel carrying control information. In this way, the second device, acting as a receiver, can receive the channel carrying data based on the control information. The data transmitter can also indicate to the receiver that there is data to be sent through the channel carrying control information.

[0021] In one possible design, the third channel is a periodic and / or semi-static configuration and / or an aperiodic channel.

[0022] In one possible design, the third channel includes a periodically and / or semi-statically configured channel.

[0023] In this design, the first device, acting as a data transmitter, can transmit data using multiple pre-configured resources or periodic resources. Therefore, the statement that data is not sent to the second device or is not expected to be sent to the second device may specifically include not sending data through the periodically and / or semi-statically configured first channel.

[0024] In one possible design, the first information is used to indicate the resource location of the first resource; or, the first information is used to indicate the period and resource location of the first resource; or, the first information is periodic information, used to indicate whether the first resource exists in the current period and / or to indicate the resource location of the first resource in the current period. Alternatively, when the first resource is replaced by a first timer and / or a first time window, the first information is used to indicate the first timer and / or the first time window. For example, the first information is used to indicate one or more of the length, start position, trigger condition, or end condition of the first timer and / or the first time window.

[0025] In one possible design, the method further includes: receiving second information, the second information being used to determine a second resource; within the second resource, receiving or expecting to receive at least one of the following from the second device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI, and / or sending or expecting to send at least one of the following to the second device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI.

[0026] In this design, the above information can be centrally sent and received within the second resource, thereby reducing power consumption.

[0027] In one possible design, the second resource is located within a resource other than the first resource. If the first resource is replaced by a first timer and / or a first time window, the second resource can be located within a resource other than the first timer and / or the first time window. Optionally, the second resource can also be replaced by a second timer and / or a second time window.

[0028] In one possible design, the first information indicates the repetition period and location of the second resource, and the first resource has a specific positional relationship with the second resource; alternatively, the first information is periodic information, used to indicate whether the second resource exists in the current period and / or to indicate the resource location of the second resource in the current period, where the first resource is a resource with a specific positional relationship to the second resource in the current period. When the second resource is replaced by a second timer and / or a second time window, the first information is used to indicate the second timer and / or the second time window, and the first resource has a specific positional relationship with the second timer and / or the second time window. For example, the first information is used to indicate one or more of the length, start position, trigger condition, or end condition of the second timer and / or the second time window.

[0029] In this design scheme, the location of the first resource can be deduced from the location of the second resource, thereby reducing signaling complexity.

[0030] In one possible design, within the second resource, at least one of the following is received or expected to be received from the second device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI, and / or at least one of the following is sent to or expected to be sent to the second device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI.

[0031] In this design, the above information can be centrally sent and received within the second resource, thereby reducing power consumption.

[0032] In one possible design, the first resource is a time-domain resource, and the resource location of the first resource is the time-domain location of the first resource; and / or, the first resource is a frequency-domain resource, and the resource location of the first resource is the frequency-domain location of the first resource.

[0033] In one possible design, the method further includes: sending third information to the second device, the third information being used by the second device to determine the first information.

[0034] In this design, the first device can send its own information to the second device to help the second device determine more suitable first information and achieve better energy-saving effect.

[0035] Secondly, a communication method is provided, which is applied to a second device or a device within the second device that communicates with a first device. Optionally, the method can be executed by the second device or by a device within the second device. The second device may be the second device itself or a logical node, logical module, or software capable of implementing all or part of the functions of the second device. The device within the second device may be a module within the second device (e.g., a processor, chip, or chip system). The second device can be a network device or a terminal device. The following description uses a second device as an example.

[0036] The method includes: acquiring first information, the first information being used to determine a first resource; within the first resource: not sending or not expecting to send at least one of the following to the first device: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI, or not sending or not expecting to send; and / or not needing to receive or not expecting to receive from the first device at least one of the following: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI, or not needing to receive or not expecting to receive. For example, the data may be a data packet carrying signaling and / or data in a higher layer, or the data may be information carried in the physical layer on a data channel or shared channel, such as a transport block (TB). For example, within the first resource, not needing to receive or not expecting to receive can be understood as the second device not receiving any signals; on the other hand, it can be understood as the second device entering sleep mode, including deep sleep, light sleep, micro-sleep, etc. Within the first resource, not sending or not expecting to send can be understood as the second device not sending any signals; on the other hand, it can be understood as the second device going into sleep, including deep sleep, light sleep, microsleep, etc.

[0037] It is understandable that obtaining the first information in the above method can be done by sending the first information after confirmation, obtaining the first information predefined by the protocol, or obtaining the first information preconfigured.

[0038] Optionally, the first resource can also be replaced by the first timer and / or the first time window. The following explanation uses the first resource as an example.

[0112] For ease of understanding, the technical terms involved in the embodiments of this application will be introduced below.

[0113] 1. Resources

[0114] In communication protocols, signals are typically configured as resources, and signals can occupy resources. Network devices allocate resources to terminal devices, and resource configurations usually include a time-frequency resource location, number of ports, time domain type (periodic / semi-static / aperiodic), etc. Resources can be uplink signal resources or downlink signal resources.

[0115] 2. Dynamic scheduling

[0116] Dynamic scheduling is a flexible scheduling method in which resources are allocated through signaling for each transmission.

[0117] Dynamic scheduling of downlink transmission can be achieved through the following steps: 1. The base station sends downlink scheduling information (DCI) to allocate corresponding physical downlink share channel (PDSCH) resources for downlink transmission. 2. The terminal device blindly detects the DCI and receives downlink transmissions on the allocated PDSCH resources.

[0118] Dynamic uplink transmission scheduling can be achieved through the following steps: 1. Uplink scheduling request (SR): The terminal device transmits an SR request on the physical uplink control channel (PUCCH) reserved by the base station. 2. The network device detects the SR on the reserved PUCCH and can then allocate a physical uplink share channel (PUSCH) through DCI scheduling. 3. The terminal device performs blind DCI detection and performs uplink transmission on the PUSCH allocated by the network device.

[0119] 3. Semi-static scheduling (SPS)

[0120] SPS scheduling, also known as semi-persistent transmission, refers to a network device using a scrambled physical downlink control channel (PDCCH) to specify the radio resources (referred to as SPS resources) to be used by a terminal device within a certain transmission time interval (TTI). After each cycle, the terminal device can use these SPS resources to send or receive data. The network device does not need to issue a PDCCH to specify the allocated resources in every scheduling time slot. Compared to dynamic scheduling, the scheduling parameters are relatively fixed and not dynamically adjusted, reducing the number of blind detections in DCI and thus lowering the latency and power consumption of the terminal device.

[0121] SPS scheduling can include downlink semi-persistent scheduling (DLSPS), uplink configured grant type 1, and uplink configured grant type 2.

[0122] Among them, (1) DL SPS: The network device configures periodic downlink resources for the terminal device; it is activated (the resource becomes a valid resource) / deactivated (the resource becomes an invalid resource) through a DCI; the terminal device can only perform downlink transmission when the resource is valid.

(3) Uplink configuration license type 2: The network device configures uplink periodic resources for the terminal device; it is activated / deactivated through a DCI; the terminal device can only perform uplink transmission when the resource is valid.

As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0130] To facilitate understanding of the embodiments of this application, let's first take... Figure 1The communication system illustrated herein is used as an example to illustrate a communication system applicable to embodiments of this application. For example, Figure 1 This is a schematic diagram of the architecture of a communication system to which the communication method provided in the embodiments of this application is applicable.

[0131] like Figure 1 As shown, this communication system mainly includes network equipment and terminal equipment. There can be multiple terminal devices or network devices. It is understood that... Figure 1 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 1 It was not drawn in the middle.

[0132] Network devices can be devices with wireless transceiver capabilities, or they can be chips or chip systems located in the access network (AN) of a communication system to provide access services to terminals. For example, network devices can be called radio access network (RAN) devices, specifically access network devices in future communication systems, or network devices in future mobile communication systems may have other naming conventions, all of which are covered within the protection scope of the embodiments of this application, and the embodiments of this application do not impose any limitations on them. Alternatively, network equipment can also include 5G, such as a gNB in ​​a New Radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a 5G base station. It can also be network nodes constituting a gNB, transmission and reception point (TRP) or transmission point (TP), or transmission measurement function (TMF), such as a central unit (CU), distributed unit (DU), CU-control plane (CP), CU-user plane (UP), or radio unit (RU), RSU with base station functionality, or wired access gateway, or 5G core network elements, etc. Alternatively, network equipment can also include: access points (APs) in Wireless Fidelity (WiFi) systems, wireless relay nodes, wireless backhaul nodes, various forms of macro base stations, micro base stations (also called small cells), relay stations, access points, wearable devices, vehicle-mounted equipment, etc.

[0133] CU and DU can be configured separately or included in the same network element, such as a baseband unit (BBU). RU can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). It is understood that network equipment can be CU nodes, DU nodes, or a combination of both. Furthermore, CUs can be classified as network equipment in the access network (RAN) or the core network (CN); there are no restrictions on this classification.

[0134] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0135] In this embodiment, the form of the network device is not limited. The device used to implement the function of the network device can be the network device itself, or it can be a device that supports the network device in implementing the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device.

[0136] The terminal equipment can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. There can be one or more terminal equipment, such as a first terminal equipment, a second terminal equipment, a third terminal equipment, etc. The terminal equipment can be a terminal equipment with transceiver functions, or it can be a chip or chip system installed in the terminal equipment. This terminal equipment can also be referred to as user equipment (UE), access terminal equipment, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal equipment, mobile device, user terminal equipment, terminal equipment, wireless communication equipment, user agent, or user device. The terminal devices in the embodiments of this application may be mobile phones, cellular phones, smartphones, tablets, wireless data cards, personal digital assistants (PDAs), wireless modems, handsets, laptop computers, machine-type communication (MTC) terminal devices, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, smart home devices (e.g., refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminal devices in autonomous driving, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical care, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, and smart homes. The terminal equipment in this application can be a wireless terminal device (e.g., a vehicle-mounted terminal device), a roadside unit (RSU) with terminal device functionality, or flying equipment (e.g., intelligent robots, hot air balloons, drones, airplanes). The terminal equipment in this application can also be a vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip, or vehicle-mounted unit integrated into a vehicle as one or more components or units, a transportation vehicle with wireless communication functionality, or a communication module. The terminal equipment can also be other devices with terminal device functionality; for example, it can be a device that functions as a terminal device in D2D communication.

[0137] The embodiments of this application do not limit the form of the terminal device. The device used to implement the functions of the terminal device can be the terminal device itself; it can also be a device that supports the terminal device in implementing the functions, such as a chip system. This device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of chips, or it can include chips and other discrete devices. The terminal device typically has a communication module, circuit, or chip that performs the corresponding communication functions. The terminal device can also be configured with program instructions for performing the corresponding communication functions.

[0138] It is understood that in the embodiments of this application, the first device can be the aforementioned terminal device or network device; the second device can be a network device or a terminal device, without limitation.

[0139] Figure 1 The communication system shown can be used in different communication system architectures; for example, it can be applied to... Figure 2 The example shown is an open-radio access network (O-RAN) system. Figure 2 As shown, the network equipment mentioned above can be a RAN (e.g., an eNB, gNB, or future access network equipment). The RAN can communicate with the core network (CN) via a backhaul link and with the UE via an air interface.

[0140] In this system, the baseband unit (BBU) in the access network equipment communicates with the core network via a backhaul link, and the radio unit (RU) in the access network equipment communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located. The BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0141] Figure 3 This is a schematic diagram of the network element function division and protocol layer structure of an O-RAN device, such as... Figure 3As shown, this includes: access network equipment and management system. In some examples, the CU is a logical node carrying the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU connects to network nodes such as the core network through interfaces, which may be interfaces such as E2 interfaces. Optionally, the CU may have some core network functions. The CU (e.g., PDCP layer and higher layers) connects to the DU (e.g., RLC layer and lower layers) through interfaces, which may be interfaces such as F1 interfaces. In some examples, these interfaces (e.g., F1 interfaces) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, and in some examples, it defines the signaling procedures of F1. The F1 interface supports the control plane F1-C and the user plane F1-U.

[0142] In some examples, the CU can be split into CU-CP and CU-UP. CU-CP is a logical node carrying the RRC layer and the control plane part of PDCP (PDCP-C) layer, used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. AMF network elements are responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the SDAP layer and the user plane part of PDCP (PDCP-U) layer, used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in terminal devices.

[0143] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0144] In some examples, a DU is a logical node that carries the radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0145] In some examples, the RU is a logical node carrying both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP TRP (Telematics Resource Planning) or a remote radio head (RRH) or other similar entity. In some examples, the Low-PHY includes portions of the PHY processing, such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0146] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include LLS-C and LLS-U interfaces providing the control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via an LLS-M interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0147] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0148] Currently, 5G communication networks have standardized many energy-saving features. In the future, the application scenarios and demands of communication technologies will become more complex. These complex scenarios and demands will lead to increased power consumption in products, posing a greater challenge to energy conservation. For base stations, high power consumption will increase operating costs; for terminals, with limited increases in size, area, and battery capacity, high power consumption and heat dissipation present even greater challenges.

[0149] When there is no ongoing signal transmission on a resource, that resource can be used for energy saving or hibernation. For example, signal transmission and reception can be suspended on that resource, or all or some components can be turned off. When a signal needs to be transmitted, the relevant components are then turned on for signal transmission. These components can be transceivers, baseband modules, RF modules, etc. Energy saving or hibernation can be further divided into different degrees, such as deep energy saving or hibernation, medium energy saving or hibernation, shallow energy saving or hibernation, micro energy saving or hibernation, and very low energy saving or hibernation. Different degrees involve different behaviors and components, and their energy consumption also differs. Based on the different switching times of different components or different energy saving or hibernation behaviors, the deeper the degree of energy saving or hibernation that can be achieved on resources that are more complete, concentrated, and have a longer duration, the better the energy saving effect.

[0150] In scenarios such as small packet transmission or burst transmission, the data sender may continuously have small data packets to send, making it impossible to sleep for extended periods or enter deep sleep. The data receiver will also be continuously woken up to receive data. Simultaneously, the data receiver will frequently monitor the downlink control channel to determine if there are data packets to receive. However, during small packet transmission or burst transmission, most control channels do not actually carry scheduling information, thus wasting the power consumption of detecting these control channels.

[0151] One possible approach is to accumulate small data packets to a certain size before sending them together. This consolidates the transmissions, reducing the dispersion of resources used in actual transmissions. This allows for longer periods of resource conservation between transmissions, thus reducing power consumption. For example, during downlink data packet scheduling, the base station can consolidate PDSCH data into several time slots, making PDSCH data scheduling more concentrated in the time domain to acquire more symbols without data transmission. Similarly, during uplink data packet scheduling, the base station can control the position of the uplink PUSCH through its allocated uplink resources, making it more concentrated in the time domain. Furthermore, during uplink data packet transmission, the terminal can accumulate packets for a period before sending SR information to notify the base station, making the uplink resources allocated by the base station more concentrated. In this approach, the sending end can accumulate packets according to its own situation, but the receiving end is unaware of this information. This causes the receiving end to perform detection on many control channels that do not actually carry scheduling information, wasting a significant amount of power in detecting these control channels.

[0152] Therefore, how to reduce power consumption is an urgent problem to be solved.

[0153] In summary, to address the aforementioned technical problems, this application proposes the following technical solutions to reduce power consumption.

[0154] The following will combine Figure 4 The communication method 400 provided in the embodiments of this application will be described in detail.

[0155] For example, Figure 4This is a flowchart illustrating a communication method 400 provided in an embodiment of this application. This communication method is applicable to communication between a first device and a second device in the aforementioned communication system. It is understood that when this method is applied to one side of the first or second device, the method may include steps performed by that side device. Optionally, the steps in this method may be performed by the first or second device, or by a device within the first or second device. The first or second device may be the first or second device itself, or a logical node, logical module, or software capable of implementing all or part of the functions of the first or second device. A device within the first or second device may be a module (e.g., a processor, chip, or chip system). The following description uses the first and second devices as examples; specifically, the communication method includes the following steps:

[0156] S410, the second device acquires the first information, and correspondingly, the first device acquires the first information. This first information is used to determine the first resource.

[0157] The phrase "the second device and the first device obtain the first information" can be understood as the second device and the first device obtaining first information predefined by the protocol, or obtaining pre-configured first information. Alternatively, it can be understood as the second device determining and sending the first information, and correspondingly, the first device receiving the first information.

[0158] The first resource can also be replaced by the first timer and / or the first time window. The following explanation uses the first resource as an example.

[0159] Based on the first information, the first device and the second device can align the first resource and the signal transmission / reception or sleep status within the first resource. The first device and / or the second device can disable related functions and reduce power consumption if there is no relevant signal reception and / or transmission within the first resource.

[0160] In one possible design, within the first resource, the second device does not send or expects to send at least one of the following to the first device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI; or, it does not send or expects to send such data. Correspondingly, within the first resource, the first device is not required to receive or expects to receive at least one of the following from the second device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI; or, it is not required to receive such data or expects to receive such data.

[0161] In this design, the second device does not transmit any of the aforementioned signals related to the first device on the first resource. Consequently, the first device can also not receive any of the aforementioned signals related to the second device within the first resource. Thus, the second device can reduce its transmission power consumption, and the first device can reduce its power consumption for maintaining reception. Furthermore, the first device can also reduce its transmission and reception power consumption based on its own signal transmission situation.

[0162] In one possible implementation, the first device and the second device can align data transmission and reception within the first resource. Condition Thus, in small packet or bursty service scenarios, the second device can aggregate packets within the first resource, thereby avoiding continuous operation of both the first and second devices due to scattered small packet transmission, and reducing the power consumption of the first and / or second devices. The data in this application can be, for example, data packets carrying signaling and / or data information in higher-layer protocols, such as MACCE, MAC PDU, or MAC SDU, or, for example, information carried on a data channel or shared channel (e.g., PDSCH or PUSCH) in physical layer protocols, such as transport blocks (TB). Data is transmitted through dynamic scheduling or semi-static scheduling.

[0163] Optionally, the second device not sending or expecting to send data to the first device may include, but not... Sending or not expecting to send includes at least one of the following: a first channel, a second channel. Correspondingly, the first device is not required to receive or does not expect to receive. Data to be received from the second device may include, but is not required to be received or is not expected to be received, at least one of the following: a first channel, The second channel. The first channel is used to carry data, and the second channel is used to carry control information.

[0164] The first channel is used to carry data. The first channel may include dynamically scheduled channels, or the first channel may be... This includes channels with periodic and / or semi-static configurations, or the first channel may include dynamically scheduled channels and periodic... Channels configured statically and / or semi-statically. Taking a second device as a network device and a first device as a terminal device as an example, the first channel may include a PDSCH dynamically scheduled by the network device for the terminal device via DCI, and / or, the first channel may include a periodic or semi-static PDSCH configured by the network device for the terminal device via RRC signaling or MAC CE signaling. Taking a second device as a terminal device and a first device as a network device as an example, the first channel may include a PUSCH dynamically scheduled by the network device for the terminal device via DCI (or UL Grant), and / or, the first channel may include a periodic or semi-static PUSCH configured by the network device for the terminal device via RRC signaling or MAC CE signaling.

[0165] For example, the method further includes step S401: A first device or a second device determines a periodic channel for the second device to send data to the first device. When data needs to be sent, the second device may send the periodic channel; when no data needs to be sent, the second device may not send the periodic channel. Accordingly, the first device performs a blind check at the resource location of the periodic channel to determine whether the second device has sent the periodic channel to the first device. This step can be before or after S410, and is not limited to this step, which is not shown in the figures. The periodic channel can be configured by either the first device or the second device. In this application, the first channel may include the periodic channel. When the periodic channel is located within a first resource, the second device does not send data to the first device on the periodic channel, and correspondingly, the first device does not receive data on the periodic channel. When the periodic channel is not located within a first resource, the second device may send data to the first device on the periodic channel, and correspondingly, the first device may receive data on the periodic channel. Thus, after configuring a periodic channel, the periodic channel can be left unused within the first resource. For example, the second device can perform packet sharding within the first resource. The solution of this application avoids the first device from continuously receiving data on the periodic resource through the first information, thereby reducing power consumption.

[0166] The second channel is used to carry control information. The second channel can be a channel transmitted on a configured periodic resource. On this periodic resource, when control information needs to be sent, the second device can send the second channel; when no control information needs to be sent, the second device can choose not to send the second channel. Correspondingly, the first device performs blind detection on the configured periodic resource to determine whether the second device has sent the second channel to the first device. This periodic resource can be configured by the first device or the second device. In this application, when the second channel is located within the first resource, the second device does not send control information to the first device on the second channel, and correspondingly, the first device does not receive control information on the second channel. When the second channel is not located within the first resource, the second device can send control information to the first device on the second channel, and correspondingly, the first device can receive control information on the second channel. Thus, the second channel can be left unused within the first resource; for example, the second device can perform packet aggregation within the first resource. The solution in this application avoids continuous blind detection on the second channel by using the first information, thereby reducing power consumption.

[0167] The control information carried by the second channel can be used to instruct the first device to receive or send data. Alternatively, the control information carried by the second channel can be used to dynamically configure channel resources for the first device to receive data, or the control information carried by the second channel can be used to schedule the first channel. Or, The control information carried by the second channel can be used to instruct the second device to have... The data needs to be sent to the first device.Alternatively, the control information carried by the second channel can be used to request the first device to configure resources for the second device to send data to the first device. For example, taking the second device as a network device and the first device as a terminal device, the second channel may include a PDCCH for carrying DCI, and the control information carried by the second channel may be DCI. Taking the second device as a terminal device and the first device as a network device, the second channel may include a PUCCH for sending SR, and the control information carried by the second channel may be SR.

[0168] In one possible implementation, the first device and the second device can align the broadcast channels within the first resource. Sending and receiving status Thus, in scenarios where the frequency of broadcast information changes is low, the second device can either not change the broadcast information it is sending or not send any broadcast information within the first resource, and / or the first device can choose not to receive any broadcast information. This avoids continuous operation of the first device and / or the second device, thereby reducing power consumption.

[0169] Specific functions may have bursty characteristics, meaning they are needed for a period of time, so the signals used for a specific function may need to be received for a period of time. In one possible implementation, the first device and the second device The equipment can align the transmission and reception of signals used for measurement, sensing, or AI within the first resource. Thus, the second device may not send the aforementioned signal within the first resource, and / or the first device may not receive the aforementioned signal. This avoids continuous operation of the first device and / or the second device, thereby reducing power consumption.

[0170] In one possible implementation, the first device and the second device can determine that there is no second [device] within the first resource. The transmission from the second device to the first device is a transmission from the second device to the first device without any signal. From another perspective, this can be understood as the first and second devices entering a state of sleep, including deep sleep, light sleep, and intermittent sleep. In this way, deep energy saving can be achieved.

[0171] In one possible design two, within the first resource, the first device does not send or expects to send at least one of the following to the second device: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI; or, it does not send or expects to send. Correspondingly, within the first resource, the second device is not required to receive or expects to receive at least one of the following from the first device: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI; or, it is not required to receive or expects to receive.

[0172] In this second design, the first device may not transmit any signals related to the second device within the first resource, and correspondingly, the second device may not receive any signals related to the first device within the first resource. Thus, the first device can reduce its transmission power consumption, and the second device can also reduce its reception power consumption. Furthermore, the second device can further reduce both transmission and reception power consumption based on its own signal transmission situation. It is understood that this second design has the opposite signal transmission and reception direction to the first design described above, and the descriptions of other aspects between the two can be used as a reference.

[0173] In one possible implementation, the first device and the second device can align data transmission and reception within the first resource. Condition .

[0174] Optionally, the second device may not need to receive or expect to receive data from the first device, and may include not needing to receive data from the first device. The device may or may not expect to receive at least one of the following: a third channel, a fourth channel. Accordingly, the first device will not send data to the second device. Or not expecting to send data to the second device may include not sending or not expecting to send at least one of the following: a third channel, The fourth channel. The third channel is used to carry data, and the fourth channel is used to carry control information.

[0175] The third channel is used to carry data. The third channel may include dynamically scheduled channels, or the third channel may be... This includes channels with periodic and / or semi-static configurations, or, alternatively, a third channel may include dynamically scheduled channels and periodic... Channels configured statically and / or semi-statically. Taking the second device as a network device and the first device as a terminal device as an example, the third channel may include PUSCH dynamically scheduled by the network device for the terminal device through DCI (or UL Grant), and / or, the third channel may include periodic or semi-static PUSCH configured by the network device for the terminal device through RRC signaling or MAC CE signaling. Taking the second device as a terminal device and the first device as a network device as an example, the third channel may include PDSCH dynamically scheduled by the network device for the terminal device through DCI, and / or, the third channel may include periodic or semi-static PDSCH configured by the network device for the terminal device through RRC signaling or MAC CE signaling.

[0176] For example, the method further includes step S402: A first device or a second device determines a periodic channel for transmitting data from the first device to the second device. When data needs to be transmitted, the first device may transmit the periodic channel; when no data needs to be transmitted, the first device may not transmit the periodic channel. Correspondingly, the second device performs a blind detection at the resource location of the periodic channel to determine whether the first device has transmitted the periodic channel to the second device. This step can occur before or after S410 or S401, and is not limited to this step, which is not shown in the figures. The periodic channel can be configured for either the first device or the second device. In this application, a third channel may include the periodic channel. When the periodic channel is located within a first resource, the first device does not transmit data to the second device on the periodic channel, and correspondingly, the second device does not receive data on the periodic channel. When the periodic channel is not located within a first resource, the first device may transmit data to the second device on the periodic channel, and correspondingly, the second device may receive data on the periodic channel.

[0177] The fourth channel is used to carry control information. The fourth channel can be a channel transmitted on a configured periodic resource. On this periodic resource, the first device can transmit the fourth channel when control information needs to be sent, and the first device can not transmit the fourth channel when no control information needs to be sent. Correspondingly, the second device performs blind detection on the configured periodic resource to determine whether the first device has transmitted the fourth channel to the second device. This periodic resource can be configured by the first device or the second device. In this application, when the fourth channel is located within the first resource, the first device does not transmit control information to the second device on the fourth channel, and correspondingly, the second device does not receive control information on the fourth channel. When the fourth channel is not located within the first resource, the first device can transmit control information to the second device on the fourth channel, and correspondingly, the second device can receive control information on the fourth channel.

[0178] The control information carried by the fourth channel can be used to instruct the second device to receive or send data. Alternatively, the control information carried by the fourth channel can be used to dynamically configure channel resources for the second device to receive data, or the control information carried by the fourth channel can be used to schedule the third channel. Or, The control information carried by the fourth channel can be used to indicate to the first device that it has... The data needs to be sent to the second device.Alternatively, the control information carried by the fourth channel can be used to request the second device to configure resources for the first device to send data to the second device. For example, taking the second device as a network device and the first device as a terminal device, the fourth channel may include a PUCCH for sending SRs, and the control information carried by the fourth channel may be SRs. Taking the second device as a terminal device and the first device as a network device, the fourth channel may include a PDCCH for carrying DCIs, and the control information carried by the fourth channel may be DCIs.

[0179] In one possible implementation, the first device and the second device can align broadcast signals within the first resource. The transmission and reception of signals used for measurement, sensing, or AI. For details, please refer to the description of one design.

[0180] In one possible implementation, the first device and the second device can determine that there is no first resource within the first resource. The transmission from the first device to the second device is a transmission without any signal from the first device to the second device. In this way, deep energy conservation can be achieved.

[0181] It should be understood that Design 1 and Design 2 described above can be combined. If the first device has no signal reception and transmission related to the second device within the first resource, and correspondingly, the second device has no signal reception and transmission related to the first device within the first resource, then the first device can reduce its power consumption for maintaining transmission and reception, and the second device can also reduce its power consumption for transmission and reception, thereby achieving better energy-saving effects at both ends. It should be understood that Design 1 and Design 2 list various signals, and in the scheme combining Design 1 and Design 2, the signals in Design 1 and Design 2 can be the same or different.

[0182] It should be understood that the names of the aforementioned signaling or channels (such as PDCCH, DCI, PDSCH, PUCCH, PUSCH, etc.) are merely examples, and future communication systems may have other channels with similar names or functions, which this application does not limit. Furthermore, the aforementioned signaling or channels can be physical layer channels, logical channels, transport channels, service flows, control flows, or security flows, which this application also does not limit.

[0183] It should be understood that the first resource can be a wireless communication resource. The first resource can be a resource comprised of at least one of the resources in the time domain, frequency domain, spatial domain, code domain, or power domain. The first resource can be continuous or discontinuous in at least one of the time domain, frequency domain, spatial domain, code domain, or power domain. In the following text, the resource location of the first resource can refer to the position of the first resource in at least one of the time domain, frequency domain, spatial domain, code domain, or power domain.

[0184] Optionally, the method further includes step S420, which is not shown in the figure.

[0185] S420: Within the second resource, the first device receives or expects to receive at least one of the following from the second device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI; and / or, the first device sends or expects to send to the second device at least one of the following: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI. Correspondingly, within the second resource, the second device sends or expects to send to the first device at least one of the following: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI; and / or, the second device receives or expects to receive at least one of the following from the first device: data, a broadcast channel, a signal for measurement, a signal for sensing, or a signal for AI. Optionally, the second resource can be all resources other than the first resource, or the second resource can be some resources other than the first resource.

[0186] In this way, data and broadcast channels can be transmitted centrally on the second resource. For example, after the second device aggregates packets in the first resource, it can transmit data centrally within the second resource, and the first device can receive data centrally within the second resource. The data received centrally in the second resource can be part or all of the data aggregated in the first resource. This achieves the goal of reducing power consumption.

[0187] For example, within the first resource, the first device does not need to receive or expect to receive at least one of the following from the second device: data, a signal for measurement, a signal for sensing, or a signal for AI; and / or does not send or expect to send to the second device at least one of the following: data, a signal for measurement, a signal for sensing, or a signal for AI. Optionally, within the first resource, the first device receives or expects to receive a broadcast channel from the second device, and / or sends or expects to send a broadcast channel to the second device. Optionally, within the second resource, the first device receives or expects to receive a broadcast channel from the second device and at least one of the following: data, a signal for measurement, a signal for sensing, or a signal for AI, and / or sends or expects to send a broadcast channel to the second device and at least one of the following: data, a signal for measurement, a signal for sensing, or a signal for AI. Accordingly, within the first resource, the second device does not send or expects to send at least one of the following to the first device: data, a signal for measurement, a signal for sensing, or a signal for AI; and / or does not need to receive or expects to receive at least one of the following from the first device: data, a signal for measurement, a signal for sensing, or a signal for AI. Optionally, within the first resource, the second device sends or expects to send a broadcast channel to the first device, and / or receives or expects to receive a broadcast channel from the first device. Optionally, within the second resource, the second device sends or expects to send a broadcast channel to the first device and at least one of the following: data, a signal for measurement, a signal for sensing, or a signal for AI, and / or receives or expects to receive a broadcast channel from the first device and at least one of the following: data, a signal for measurement, a signal for sensing, or a signal for AI.

[0188] The second resource can be indicated by the first information, or it can be indicated by the second information. Alternatively, it can be indicated by both the first and second information.

[0189] Optionally, the second resource can also be replaced by a second timer and / or a second time window. The following explanation uses the second resource as an example.

[0190] The second information can be information sent from the first device to the second device, or information sent from the second device to the first device. Optionally, the method further includes steps S403 or S404, which are not shown in the figures.

[0191] S403: The second device sends the second information, and correspondingly, the first device receives the second information, which is used to determine the second resource.

[0192] S404: The first device sends the second information, and correspondingly, the second device receives the second information, which is used to determine the second resource.

[0193] Optionally, the first device receiving or expecting to receive data from the second device may include the first device receiving or expecting to receive at least one of the following: a first channel and a second channel.

[0194] Optionally, the first device sending or expecting to send data to the second device may include the first device sending or expecting to send at least one of the following: a third channel or a fourth channel.

[0195] Optionally, the second device sending or expecting to send data to the first device may include the second device sending or expecting to send at least one of the following: a first channel and a second channel.

[0196] Optionally, the second device receiving or expecting to receive data from the first device may include the second device receiving or expecting to receive at least one of the following: a third channel or a fourth channel.

[0197] It is understood that the second resource and the first resource are corresponding. For the description of the first channel, the second channel, the third channel, the fourth channel and the above signals, please refer to the description in step S410.

[0198] As described above, the first information is sent from the second device to the first device, and this first information is used to determine the first resource. Thus, the first device can determine the location of the first resource based on the first information. Optionally, this method also includes second information, which can be sent from the first device to the second device, or vice versa, and is used to determine the second resource. Thus, the first device can determine the location of the second resource based on the second information. In one possible approach, the first resource and the second resource have a specific positional relationship, so the location of the first resource can be deduced from the location of the second resource; that is, the first information indicates the location of the second resource, and the first device can determine the location of the first resource based on the positional relationship between the second and first resources.

[0199] In one possible embodiment, the first or second information can be information sent from the network device to the terminal device. Optionally, the first or second information can be carried on RRC signaling, MAC CE signaling, or a physical layer protocol channel or signal used to carry control information (e.g., PDCCH, wake-up signal, or newly added DCI information). In another possible embodiment, the first or second information can be information sent from the terminal device to the network device. Optionally, the first or second information can be carried on a physical layer protocol channel or signal used to carry control information (e.g., PUCCH, SR, or newly added UCI information).

[0200] The first information and the second information can be different information or the same information. The first information and the second information can also be inclusive, for example, the first information includes the second information, or the second information includes the first information. The first information and the second information can be carried in the same signaling and / or information element and / or field, or they can be carried in different signaling and / or information element and / or field.

[0201] The first or second piece of information will be explained in detail below.

[0202] Case 1: The first information indicates the resource location of the first resource.

[0203] In Case 1, the resource location of the first resource can be directly indicated by the first information, i.e., a display indication; or the resource location of the first resource can be indicated by indicating some parameters by the first information, combined with at least one of the parameters carried in predefined parameters, predefined rules, or other signaling.

[0204] Taking the first resource as a time-domain resource as an example, the first information can indicate at least one of the following: the duration of the first resource, the start time of the first resource, or the end time of the first resource. The start time or end time of the first resource can be derived from the location of the resource carrying the first information. For example, the first information can be carried on a DCI or PDCCH, and the start time or end time of the first resource can be derived from the time location of the DCI or PDCCH. For example, the time after the first duration of the end time of the DCI or PDCCH is the start time of the first resource.

[0205] Scenario 2: The first information indicates the repetition cycle and location of the first resource.

[0206] In scenario 2, the repetition period and location of the first resource can be directly indicated through the first information, i.e., a display indication; alternatively, the first information can indicate some parameters, which, in combination with at least one of the parameters carried in predefined parameters, predefined rules, or other signaling, can indicate the repetition period and location of the first resource. The parameters indicating the repetition period and resource location can be within the same signaling and / or the same information element (IE), or within different signaling and / or different IEs, without limitation.

[0207] Taking the first resource as a time-domain resource as an example, the first information can indicate at least one of the following: the duration of the first resource, the start time of the first resource, the end time of the first resource, the repetition period of the first resource, and the offset value of the first resource within the repetition period.

[0208] Figure 5 This is a schematic diagram of a first resource provided in an embodiment of this application. For example... Figure 5 Taking the transmission of data packets from a network device to a terminal device as an example, the first resource is a periodically repeating resource. Within the first resource, when a data packet arrives at the network device, the network device delays the transmission of the data packet, i.e., it performs packet aggregation. In resources outside the first resource, the network device transmits data packets to the terminal device, which may include data packets arriving within the first resource. In resources outside the first resource, the network device can transmit data packets to the terminal device through dynamic scheduling or through semi-statically configured resources; this application does not restrict the specific scheduling method.

[0209] Figure 6 This is a schematic diagram of a first resource provided in an embodiment of this application. For example... Figure 6 Taking the sending of data packets from a terminal device to a network device as an example, the first resource is a periodically repeating resource. Within the first resource, when a data packet arrives at the terminal device, the terminal device may delay sending the data packet or delay sending information indicating that a data packet needs to be sent (such as an SR), i.e., packet sharding. Within resources outside the first resource, the terminal device can send data packets to the network device, which may include data packets arriving within the first resource. Within resources outside the first resource, the terminal device can send data packets to the network device through semi-statically configured resources, or it can first send information indicating that a data packet needs to be sent (such as an SR) to the network device, and then send the data packet according to the network device's scheduling information. This application does not limit the specific scheduling method.

[0210] Figure 5 or Figure 6In the illustrated embodiment, the second resource can be understood as a resource for dynamic scheduling of data packets, or as a resource for semi-static configuration of data packets, or as all resources other than the first resource, without limitation.

[0211] Case 3: The first information is periodic information, which is used to indicate whether the first resource exists in the current period and / or to indicate the resource location of the first resource in the current period.

[0212] In scenario 3, a fixed repetition period for receiving the first information can be agreed upon, allowing the first device to periodically detect the first information to determine the configuration of the first resource in the current period. This repetition period can be configured by either the first device or the second device. In scenario 3, the first information can directly indicate whether the first resource exists in the current period and / or indicate the resource location of the first resource in the current period; alternatively, the first information can indicate some parameters, combined with at least one of predefined parameters, predefined rules, or parameters carried in other signaling, to indicate whether the first resource exists in the current period and / or indicate the resource location of the first resource in the current period. The first resource within a single period can be one or more, or it can be understood that the first resource within a single period can be continuous or discontinuous.

[0213] In one possible embodiment, the location of the first resource is the same in each cycle. Optionally, the first information may only indicate whether the first resource exists in the current cycle. In another possible embodiment, the location of the first resource may be different in each cycle. Optionally, the first information may indicate the location of the first resource in the current cycle to obtain greater configuration flexibility.

[0214] Taking the first resource as a time-domain resource as an example, the first information can indicate at least one of the following: whether the first resource exists in the current period, the duration of the first resource, the start time of the first resource, the end time of the first resource, and the offset value of the first resource within the repetition period of the first information.

[0215] Figure 7 This is a schematic diagram of a first resource provided in an embodiment of this application. For example... Figure 7Taking the transmission of data packets from a network device to a terminal device as an example, the first information can be information sent from the network device to the terminal device, or information sent from the terminal device to the network device. The first information indicates whether a first resource exists within the current period, and / or the location of the first resource. Within the first resource, when a data packet arrives at the network device, the network device will delay sending the data packet, i.e., perform packet aggregation. Within resources outside the first resource, the network device sends data packets to the terminal device, which may include data packets arriving within the first resource. Within resources outside the first resource, the network device can send data packets to the terminal device through dynamic scheduling or through semi-statically configured resources; this application does not limit the specific scheduling method.

[0216] Figure 8 This is a schematic diagram of a first resource provided in an embodiment of this application. For example... Figure 8 Taking the sending of data packets from a terminal device to a network device as an example, the first information can be information sent from the network device to the terminal device, or information sent from the terminal device to the network device. Within the first resource, when a data packet arrives at the terminal device, the terminal device may delay sending the data packet or delay sending information indicating that there is a data packet to be sent (such as an SR), i.e., packet merging. Within resources outside the first resource, the terminal device can send data packets to the network device, which may include data packets arriving within the first resource. Within resources outside the first resource, the terminal device can send data packets to the network device through semi-statically configured resources, or it can first send information indicating that there is a data packet to be sent (such as an SR) to the network device, and then send the data packet according to the scheduling information of the network device. This application does not limit the specific scheduling method.

[0217] Figure 7 or Figure 8 In the illustrated embodiment, the second resource can be understood as a resource for dynamic scheduling of data packets, or as a resource for semi-static configuration of data packets, or as all resources other than the first resource, without limitation.

[0218] Case 4: The second information indicates the resource location of the second resource.

[0219] The instructions for Case 4 are similar to those for Case 1. You can refer to the description in Case 1, replace the first information with the second information, and replace the first resource with the second resource.

[0220] Case 5: The second information indicates the repetition cycle and location of the second resource.

[0221] The instructions for Case 5 are similar to those for Case 2. You can refer to the description in Case 2, replace the first information with the second information, and replace the first resource with the second resource.

[0222] Case 6: The second information is periodic information, which is used to indicate whether the second resource exists in the current period and / or to indicate the resource location of the second resource in the current period.

[0223] The instructions for Case 6 are similar to those for Case 3. You can refer to the description in Case 3, replacing the first information with the second information and the first resource with the second resource.

[0224] The above situations 1-3 and 4-6 can be combined with each other.

[0225] Case 7: The first information indicates the repetition cycle and location of the second resource.

[0226] In Case 7, the first information indicating the repetition period and location of the second resource is similar to that in Case 2, where the first information indicating the repetition period and location of the first resource can be used as a reference, replacing the first resource with the second resource. If the repetition period and location of the second resource are determined through the first information, the repetition period and location of the first resource can be determined according to predefined rules. For example, the first resource could be all resources other than the second resource, or the first resource could be a resource with a specific positional relationship to the second resource.

[0227] In one possible embodiment, the second resource can be a periodic resource indicated by a PDCCH search space used for packet aggregation or energy saving, on which the terminal device blindly detects downlink control information. In another possible embodiment, the second resource can be a PDCCH candidate periodic resource where a DCI scrambled by RNTI for packet aggregation or energy saving resides, on which the terminal device blindly detects downlink control information scrambled by RNTI for packet aggregation or energy saving. In yet another possible embodiment, the second resource can be a periodic resource for semi-static configuration of data packets.

[0228] For example, the start or end time of the first resource within a period can be derived from the resource location of the second resource. For instance, the start or end time of the first resource within a period can be the time following the first duration of the end time of the second resource within that period.

[0229] Case 8: The first information is periodic information. The first information is used to indicate whether the second resource exists in the current period and / or to indicate the resource location of the second resource in the current period. The first resource is a resource other than the second resource in the current period.

[0230] In Case 8, the indication method of the first information is similar to that in Case 3. Refer to the description in Case 3 and replace the first resource with the second resource. If the resource location of the second resource in the current period is determined through the first information, the resource location of the first resource can be determined according to predefined rules. For example, the first resource may be all resources other than the second resource in the current period, or the first resource may be a resource with a specific positional relationship to the second resource.

[0231] In one possible embodiment, the second resource may be a resource location for transmitting data packets in the current cycle as scheduled or indicated by the first information, or the second resource may be a semi-statically configured resource for transmitting data packets in the current cycle activated by the first information.

[0232] For example, the start or end time of the first resource within a period can be derived from the resource location of the second resource. For instance, the start time of the first resource within a period can be the end time of the second resource within that period or a time after a first duration following the end time of the second resource.

[0233] Optionally, in cases 1-8 above, the repetition period of the first information, the repetition period of the first resource, and the repetition period of the second resource can be determined based on the service requirements of one or more of the following: data, broadcast channel, signal for measurement, signal for sensing, or signal for AI. For example, the repetition period may be less than or equal to a service latency threshold.

[0234] Optionally, the location of the first information or the first resource is related to the resource location corresponding to MIB, SIB1, OSI, or Paging.

[0235] Optionally, Design 1 and Design 2, as described above, can be combined with each other. The first device may not receive or transmit the aforementioned signals related to the second device within the first resource; correspondingly, the second device may not receive or transmit the aforementioned signals related to the first device within the first resource. Figure 9 , Figure 10 This diagram illustrates a first resource provided in an embodiment of this application, in which a network device and a terminal device exchange data packets. The specific indication methods for the first and second resources can be referred to in cases 1-8 above, and will not be repeated here.

[0236] like Figure 9The first resource is a periodically repeating resource. Within the first resource, when a data packet arrives at the network device or terminal device, the network device will delay sending the data packet, the terminal device will delay sending the data packet, or the terminal device will delay sending information indicating that there is a data packet to be sent (such as an SR), i.e., packet aggregation. Within resources outside the first resource, the network device sends data packets to the terminal device and / or the terminal device sends data packets to the network device, which may include data packets arriving within the first resource. Within resources outside the first resource, data packets can be sent through dynamic scheduling or through semi-statically configured resources; this application does not limit the specific scheduling method. See Cases 2 and 7.

[0237] like Figure 10 The first information can be information sent from the network device to the terminal device, or information sent from the terminal device to the network device. The first information indicates whether a first resource exists in the current period, and / or the location of the first resource; or, the first information indicates whether a second resource exists in the current period, and / or the location of the second resource, and the location of the first resource is determined by a predetermined rule. Within the first resource, when a data packet arrives at the network device or the terminal device, the network device will delay sending the data packet, the terminal device will delay sending the data packet, or the terminal device will delay sending information indicating that there is a data packet to be sent (such as an SR), i.e., packet aggregation. Within resources other than the first resource, the network device sends data packets to the terminal device and / or the terminal device sends data packets to the network device, which may include data packets arriving within the first resource. Within resources other than the first resource, data packets can be sent through dynamic scheduling or through semi-statically configured resources; this application does not limit the specific scheduling method. See cases 3 and 8.

[0238] Optionally, this method also includes step S430, which is not shown in the figure.

[0239] S430: The first device sends third information, and correspondingly, the second device receives the third information, which is used by the second device to determine the first information.

[0240] In this way, the first device can send its own information to the second device via a third-party information provider to negotiate the location of the first resource. For example, the first device can send its packet-gathering time to the second device, which can then determine the location of the first resource based on this information. This allows for negotiation to determine a more suitable location for the first resource in a two-end scenario, achieving better energy-saving results.

[0241] In the above method, the first resource can be used for sleep, energy saving, packet accumulation, or no signal transmission / reception within the first resource. A device that supports sleep, energy saving, packet accumulation, or no signal transmission / reception within the first resource in the above method can be described as supporting packet accumulation capability, packet accumulation transmission capability, etc. From another perspective, a device that supports instructing the first resource through first information and performing sleep, energy saving, packet accumulation, or no signal transmission / reception within the first resource in the above method can be described as supporting the capability of instructing the first resource through first information or dynamic packet accumulation capability, etc.; a device that supports instructing the second resource through first information and / or second information and performing sleep, energy saving, packet accumulation, or no signal transmission / reception outside the second resource in the above method can be described as supporting the capability of instructing the second resource through first information and / or second information or dynamic transmission capability, etc.

[0242] Optionally, this method further includes sending capability information, which can be information sent from the first device to the second device, or information sent from the second device to the first device. This capability information indicates that the capability information sending device supports one or more of the following capabilities: packet aggregation capability, packet aggregation and sending capability, the ability of first information to indicate a first resource (or dynamic packet aggregation capability), and the ability of first information and / or second information to indicate a second resource (or dynamic sending capability).

[0243] When the first device and / or the second device executes the above method, it can be referred to as enabling the packet aggregation function. It is understood that this function may also have other names, such as sending function, packet aggregation and sending function, without limitation. The following uses the packet aggregation function as an example.

[0244] Optionally, this method also includes enabling the package aggregation function when the first condition is met. The first condition may include one or more of the following:

[0245] The terminal's moving speed is greater than a certain speed;

[0246] The terminal data rate is less than a certain threshold;

[0247] The base station is under light traffic load.

[0248] Base station resource utilization is below a certain threshold;

[0249] Base station idle times (e.g., at night, late at night, etc.);

[0250] The business requires that the rate or latency, or QoS flow, or SLA (Service Level Agreement) metrics meet a certain numerical condition or a certain threshold;

[0251] Enable energy-saving mode (terminal energy saving, base station energy saving, dual-end energy saving mode).

[0252] The above combination Figure 4 The communication method provided in the embodiments of this application is described in detail. The communication apparatus used to perform the communication method provided in the embodiments of this application is described in detail below.

[0253] Figure 11 This is a schematic diagram of the structure of the communication device provided in the embodiments of this application. Figure 1 For example, such as Figure 11 As shown, the communication device 1300 includes a transceiver module 1301 and a processing module 1302. For ease of explanation, Figure 11 Only the main components of the communication device 1300 are shown.

[0254] The transceiver module 1301 is used to perform the above. Figure 4 The sending and receiving functions of the method shown are executed by the processing module 1302. Figure 4 The method shown includes functions other than sending and receiving.

[0255] Optionally, the transceiver module 1301 may include a transmitting module ( Figure 11 (not shown in the image) and receiving module ( Figure 11 (Not shown in the image). The transmitting module is used to implement the transmitting function of the communication device 1300, and the receiving module is used to implement the receiving function of the communication device 1300.

[0256] Optionally, the communication device 1300 may also include a storage module. Figure 11 (Not shown in the image), the storage module stores programs or instructions. When the processing module 1302 executes the program or instructions, the communication device 1300 can perform the above-described method. Figure 4 The functions of the first device and / or the second device in the method shown.

[0257] It is understood that the communication device 1300 may be a terminal device, or a chip (system) or other component or assembly that can be disposed in a terminal device, or a device that includes a terminal device; or, the communication device 1300 may be a network device, or a chip (system) or other component or assembly that can be disposed in a network device, or a device that includes a network device.
