[0002] The present application relates to the field of communication, and in particular to a communication method and apparatus. BACKGROUND

[0003] At present, many energy saving features are standardized in the fifth generation (5th generation, 5G) communication network. In the future, the application scenarios and requirements of communication technology will be more complex. The complex scenarios and requirements make the power consumption of products also increase accordingly, and the energy saving problem also faces greater challenges. For the base station, the large power consumption will increase more operating costs; for the terminal, the volume, area and battery capacity are limited to grow, and the large power consumption and heat dissipation problems bring greater challenges.

[0004] Therefore, how to reduce power consumption is a problem to be solved. SUMMARY

Optionally, the method can be executed by the first device or the apparatus in the first device. The first device, for example, is the first device itself or a logical node, a logical module or software that can realize all or part of the functions of the first device. The apparatus in the first device, for example, is a module (such as a processor, a chip, or a chip system, etc.) in the first device. The first device can be a terminal device or a network device. The following is described taking the first device as an example.

The base station sends downlink scheduling information (DCI) to allocate corresponding physical downlink shared channel (PDSCH) resources for downlink transmission. 2. The terminal device blindly detects the DCI and receives the downlink transmission on the allocated PDSCH resource.

[0119] Dynamic scheduling uplink transmission, the specific steps can include: 1. Uplink scheduling request (scheduling request, SR), that is, the terminal device transmits the SR request on the physical uplink control channel (physical uplink control channel, PUCCH) reserved according to the base station configuration. 2. The network device detects the SR on the reserved PUCCH, and then can schedule and allocate the physical uplink shared channel (physical uplink share channel, PUSCH) through the DCI. 3. The terminal device blindly detects the DCI, and transmits the uplink on the PUSCH according to the PUSCH resource allocated by the network device.

[0120] 3. Semi-static scheduling (semi-persistent scheduling, SPS)

[0121] SPS scheduling can also be called semi-persistent transmission, which can refer to that the network device specifies the wireless resources (hereinafter referred to as SPS resources) used by the terminal device using a scrambled physical downlink control channel (physical downlink control channel, PDCCH) in a certain transmission time interval (transmission time interval, TTI), and the terminal device can use the SPS resources to receive or transmit data every period. The network device does not need to issue a PDCCH to specify the allocated resources in each scheduling time slot. Compared with dynamic scheduling, the scheduling parameters are relatively fixed, and are not dynamically adjusted, reducing the number of blind detection of DCI, which can reduce the latency and power consumption of the terminal device.

[0122] SPS scheduling can include downlink semi-persistent scheduling (downlink semi-persistent scheduling, DL SPS), uplink configured grant type 1 (type 1), and uplink configured grant type 2 (type 2).

[0123] Among them, (1) DL SPS: the network device configures periodic downlink resources for the terminal device; activate (the resource becomes a valid resource) / deactivate (the resource becomes an invalid resource) through a DCI; the terminal device can only perform downlink transmission when the resource is valid. (2) Uplink configured grant type 1: the network device configures uplink periodic resources for the terminal device; once configured, the resource is valid, and the validity and invalidity of the resource do not need to be activated / deactivated by DCI, and can only be changed by RRC reconfiguration, for example, the resource is released by the method of RRC reconfiguration. (3) Uplink configured grant type 2: the network device configures uplink periodic resources for the terminal device; activate / deactivate through a DCI; the terminal device can only perform uplink transmission when the resource is valid.

The terminal device can also be other devices with terminal device functions, for example, the terminal device can also be a device with terminal device functions in D2D communication.The terminal device can also be referred to simply as a terminal.

[0138] Embodiments of the present application do not limit the form of the terminal device, and the device for implementing the function of the terminal device can be a terminal device, or a device capable of supporting the terminal device to implement the function, such as a chip system. The device can be installed in the terminal device or used in matching with the terminal device. In embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. The terminal device is usually provided with a communication module, circuit or chip for executing corresponding communication functions. The terminal device also has program instructions configured to execute corresponding communication functions.

[0139] It can be understood that in embodiments of the present application, the first device can be the terminal device or the network device described above; the second device can be the network device or the terminal device, without limitation.

[0140] The communication system shown in FIG. 1 can be used for the architecture of different communication systems, for example, it can be applicable to the open-radio access network (O-RAN) system shown in FIG. 2. As shown in FIG. 2, the network device described above can be a RAN (for example, it can be an eNB or a gNB or a future access network device). The RAN can communicate with the core network (CN) through a backhaul link, and communicate with the UE through an air interface.

[0141] Among them, the baseband unit (BBU) in the access network device communicates with the core network through the backhaul link, and the radio unit (RU) in the access network device communicates with at least one UE through the air interface. The BBU communicates with at least one RU through a fronthaul link, and the BBU and the RU can be co-located or not. The BBU includes at least one CU and at least one DU, which can communicate through at least one midhaul.

[0142] Figure 3 is a schematic diagram of a network element function split and protocol layer structure of an O-RAN device, as shown in Figure 3, including an access network device and a management system. In some examples, the CU is a logical node that carries a radio resource control (RRC) layer, a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as a core network through some interfaces, which can be E2 interfaces or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the RLC layer and lower layers) through some interfaces, which can be F1 interfaces or the like. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). The F1AP is an application protocol of the F1 interface, which defines the signaling procedures of the F1 in some examples. The F1 interface supports a control plane F1-C and a user plane F1-U.

[0143] In some examples, the CU can be split into a CU-CP and a CU-UP, where the CU-CP is a logical node that carries an RRC layer and a control plane part of a PDCP (PDCP-C) layer, and is used to implement the control plane functions of the CU. The CU-CP can interact with a network element in the core network that is used to implement the control plane functions. The network element in the core network that is used to implement the control plane functions can be an access and mobility function network element, such as an access and mobility management function (AMF) in a 5G system. The AMF network element is used to be responsible for mobility management in a mobile network, such as location updating of a terminal device, registration of the terminal device to a network, handover of the terminal device, etc. The CU-UP is a logical node that carries an SDAP layer and a user plane part of a PDCP (PDCP-U) layer, and is used to implement the user plane functions of the CU. The CU-UP can interact with a network element in the core network that is used to implement the user plane functions. The network element in the core network that is used to implement the user plane functions, for example, a user plane function (UPF) in a 5G system, is used to be responsible for forwarding and receiving data in a terminal device.

[0144] The above configuration of CU and DU is merely an example, and the CU and DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have functions of more protocol layers, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to a service type or other system requirements, for example, according to a delay requirement. For example, functions that require a processing time to meet a delay requirement are arranged in the DU, and functions that do not require the delay requirement are arranged in the CU.

[0145] In some examples, the DU is a logical node that carries a radio link control (RLC) layer, a medium access control (MAC) layer, a higher physical layer (Higher PHY), and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY includes part of the PHY processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and other processing functions.

[0146] In some examples, the RU is a logical node that carries a lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3rd generation partnership project (3GPP) TRP or a remote radio head (RRH) or other similar functional entity. In some examples, the Low-PHY includes part of the PHY processing, such as fast Fourier transform (FFT), inverse fast fourier transformation (IFFT), digital beamforming and filtering, and other processing functions. The RU communicates with one or more UEs through a wireless link.

[0147] The DU and the RU can or can not be co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split-control, user and synchronization (LLS-CUS) interface over a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide a control plane (C-Plane) and a user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operation between the DU and the RU.

[0148] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or to implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a portion of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another portion of the functions of the PHY layer that are closer to the intermediate radio frequency side.

[0149] At present, many energy saving features are standardized in the fifth generation (5G) communication network. In the future, the application scenarios and requirements of communication technology will be more complex. The complex scenarios and requirements increase the power consumption of products accordingly, and the energy saving problem thus faces greater challenges. For a base station, large power consumption increases more operating costs; for a terminal, large power consumption and heat dissipation problems bring greater challenges in the case of limited growth of volume, area and battery capacity.

[0150] When there is no ongoing signal transmission on some resources, the resources can be used for energy saving or sleep, for example, no signal transmission is performed on the resources, all or part of the components are turned off, and the like, and when there is a signal to be transmitted, the relevant components are turned on for signal transmission. The components can be transceivers, baseband modules, radio frequency modules, and the like. Energy saving or sleep can be further divided into different degrees, for example, deep energy saving or sleep, moderate energy saving or sleep, shallow energy saving or sleep, micro energy saving or sleep, and pico energy saving or sleep. Different degrees involve different behaviors and components, and different energy consumptions. Based on different lengths of switching time of different components or different energy saving or sleep behaviors, the deeper the energy saving or sleep degree achieved on the more complete, concentrated, and longer resources, the better the energy saving effect.

[0151] In a scenario such as a small packet transmission or a burst transmission, a data sending end can continuously have small data packets to be sent, and cannot sleep for a long time or enter deep sleep. The data receiving end is also continuously woken up to receive data. Meanwhile, the data receiving end frequently monitors a downlink control channel to determine whether there is a data packet to be received. However, in the small packet transmission or the burst transmission process, most of the control channels do not actually carry scheduling information, and therefore, the power consumption of detecting these control channels is wasted.

[0152] A possible way is to accumulate small data packets to a certain extent and then send them together, so as to concentrate the transmission and reduce the dispersion of resources occupied in actual transmission. In this way, the terminal can save power for a longer time on the resources between transmissions, thereby reducing power consumption. For example, in the downlink data packet scheduling process, the base station can concentrate the PDSCH data scheduling on several time slots for transmission, so as to make the PDSCH data scheduling more concentrated in the time domain and obtain more symbols without data transmission. For another example, in the uplink data packet scheduling process, the base station can control the position of the uplink PUSCH through the uplink resource allocated by the base station, so as to make the uplink PUSCH more concentrated in the time domain. For another example, in the uplink data packet transmission process, the terminal can accumulate data packets for a period of time and then send SR information to notify the base station, so that the uplink resource allocated by the base station is more concentrated. In this way, the sending end can accumulate data packets according to its own situation, and the receiving end does not know the information, which causes the receiving end to detect a large amount of control channels that do not actually carry scheduling information, thereby wasting a large amount of power consumption of detecting these control channels.

[0153] Therefore, how to reduce power consumption is a problem to be solved.

[0154] In summary, in view of the above technical problems, the embodiments of the present application provide the following technical solutions to reduce power consumption.

[0155] The communication method 400 provided by the embodiments of the present application will be described in detail below with reference to FIG. 4.

[0156] For example, FIG. 4 is a flow diagram of a communication method 400 provided by the embodiments of the present application. The communication method is applicable to the communication between the first device and the second device in the communication system described above. It can be understood that when the method is applicable to one side of the first device or the second device, the method can include the steps performed by the side device. Optionally, the steps in the method can be performed by the first device or the second device, or by the apparatus in the first device or the second device. The first device or the second device, for example, the first device or the second device itself, or a logical node, a logical module or software capable of realizing all or part of the functions of the first device or the second device. The apparatus in the first device or the second device, for example, a module (such as a processor, a chip, or a chip system, etc.) in the first device or the second device. The following is described by taking the first device and the second device as examples. Specifically, the communication method includes the following steps:

[0157] S410, the second device acquires the first information, and correspondingly, the first device acquires the first information. The first information is used to determine the first resource.

[0158] It can be understood that the second device and the first device acquiring the first information means that the second device and the first device acquire the first information predefined by the protocol, or acquire the first information pre-configured. Alternatively, the second device and the first device acquiring the first information means that the second device determines and sends the first information, and correspondingly, the first device receives the first information.

[0159] The first resource can also be replaced by a first timer and / or a first time window. The following is described by taking the first resource as an example.

[0160] Through the first information, the first device and the second device can align the first resource and the signal transmission or reception or sleep condition in the first resource. The first device and / or the second device can not receive and / or send relevant signals in the first resource, so as to close the relevant functions and reduce the power consumption.

[0161] In a possible design, in the first resource, the second device does not send or does not expect 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 does not perform the sending or does not expect to perform the sending. Correspondingly, in the first resource, the first device does not need to receive or does not expect 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 does not need to perform the receiving or does not expect to perform the receiving.

[0162] In the first design, the second device does not send the above-mentioned signal related to the first device on the first resource, and accordingly, the first device can not receive the above-mentioned signal related to the second device on the first resource. In this way, the second device can reduce the transmission power consumption, and the first device can reduce the power consumption of keeping receiving. Further, the first device can also reduce the power consumption of transmission and reception in combination with its own signal transmission situation.

[0163] In a possible implementation, the first device and the second device can align the data transmission and reception situation in the first resource. In this way, in a small packet or burst traffic scenario, the second device can accumulate packets in the first resource, thereby avoiding the continuous work of the first device and the second device caused by the transmission of scattered small packets, and further reducing the power consumption of the first device and / or the second device. The data in the present application may, for example, be a data packet carrying signaling and / or data information in a high layer protocol, such as a MAC CE, a MAC PDU or a MAC SDU, or the data in the present application may, for example, be information carried in a data channel or a shared channel (such as a PDSCH or a PUSCH) in a physical layer protocol, such as a transport block (TB). The data is transmitted by means of dynamic scheduling or semi-static scheduling.

[0164] Optionally, the second device does not send or does not expect to send data to the first device, which may, for example, include not sending or not expecting to send at least one of the following: a first channel, a second channel. Accordingly, the first device does not need to receive or does not expect to receive data from the second device, which may, for example, include not receiving or not expecting to receive at least one of the following: a first channel, a second channel. The first channel is used to carry data, and the second channel is used to carry control information.

[0165] The first channel is used to carry data. The first channel may, for example, include a dynamically scheduled channel, or the first channel may, for example, include a periodic and / or semi-statically configured channel, or the first channel may, for example, include a dynamically scheduled channel and a periodic and / or semi-statically configured channel. Taking the second device as a network device and the first device as a terminal device as an example, the first channel may, for example, include a PDSCH dynamically scheduled by the network device for the terminal device through DCI, and / or the first channel may, for example, include a periodic or semi-static PDSCH semi-statically 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 first channel may, for example, include a PUSCH dynamically scheduled by the network device for the terminal device through DCI (or referred to as UL Grant), and / or the first channel may, for example, include a periodic or semi-static PUSCH semi-statically configured by the network device for the terminal device through RRC signaling or MAC CE signaling.

[0166] The method further includes, for example, a step S401 in which the first device or the second device determines a periodic channel used by the second device to send data to the first device. When there is data to be sent, the second device can send the periodic channel, and when there is no data to be sent, the second device can not send the periodic channel. Accordingly, the first device performs blind detection on a resource position 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. This step is not shown in the figure. The periodic channel can be configured for the first device or the second device. In this application, the first channel can include the periodic channel. When the periodic channel is located in the first resource, the second device does not send data to the first device on the periodic channel, and accordingly, the first device does not receive data on the periodic channel. When the periodic channel is not located in the first resource, the second device can send data to the first device on the periodic channel, and accordingly, the first device can receive data on the periodic channel. In this way, after the periodic channel is configured, the periodic channel can not be used in the first resource, for example, the second device can perform packet accumulation in the first resource, and the scheme of the present application avoids the first device from continuously receiving data on the periodic resource through the first information, thereby reducing power consumption.

[0167] The second channel is used to carry control information. The second channel can be a channel transmitted on a configured periodic resource. On the periodic resource, when there is control information to be sent, the second device can send the second channel, and when there is no control information to be sent, the second device can not send the second channel. Accordingly, 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. The periodic resource can be configured for the first device or the second device. In this application, when the second channel is located in the first resource, the second device does not send control information to the first device on the second channel, and accordingly, the first device does not receive control information on the second channel. When the second channel is not located in the first resource, the second device can send control information to the first device on the second channel, and accordingly, the first device can receive control information on the second channel. In this way, the second channel can not be used in the first resource, for example, the second device can perform packet accumulation in the first resource, and the scheme of the present application avoids the first device from continuously performing blind detection on the second channel through the first information, thereby reducing power consumption.

[0168] The control information carried by the second channel can be used to instruct the first device to receive or transmit data, or 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. Alternatively, the control information carried by the second channel can be used to indicate that the second device has data to send to the first device, or 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, the second device is a network device, and the first device is a terminal device. The second channel can include a PDCCH used to carry DCI, and the control information carried by the second channel can be DCI. For example, the second device is a terminal device, and the first device is a network device. The second channel can include a PUCCH used to send an SR, and the control information carried by the second channel can be an SR.

[0169] In a possible implementation, the first device and the second device can align the transmission and reception of the broadcast channel in the first resource. In this way, in a scenario where the frequency of change of the broadcast information is low, the second device can not change the broadcast information transmitted in the first resource or not transmit the broadcast information, and / or the first device can not receive the broadcast information. Thus, the first device and / or the second device can be prevented from working continuously, thereby reducing power consumption.

[0170] A specific function can have a burst feature, i.e., it is needed for a period of time, and therefore a signal used for the specific function can need to be received for a period of time. In a possible implementation, the first device and the second device can align the transmission and reception of a signal used for measurement, a signal used for sensing, or a signal used for AI in the first resource. In this way, the second device can not transmit the above signals in the first resource, and / or the first device can not receive the above signals. Thus, the first device and / or the second device can be prevented from working continuously, thereby reducing power consumption.

[0171] In a possible implementation, the first device and the second device can determine that there is no transmission from the second device to the first device in the first resource, i.e., there is no transmission of any signal from the second device to the first device, which can be understood as the first device and the second device sleeping, including deep sleep, light sleep, micro sleep, etc. In this way, deep energy saving can be achieved.

[0172] In a possible design II, the first device does not send or does not expect to send, within the first resource, 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, or does not perform or does not expect to perform the sending.

[0173] In the design II, the first device can not send the above signals related to the second device within the first resource, and correspondingly, the second device does not receive or does not expect to receive the above signals related to the first device within the first resource. In this way, the first device can reduce power consumption of the sending, and the second device can reduce power consumption of the receiving, and the second device can further reduce power consumption of the sending and the receiving in combination with the signal sending of the second device. It can be understood that the design II is opposite to the signal sending and receiving directions in the design I, and the descriptions in other aspects can be referred to each other.

[0174] In a possible implementation, the first device and the second device can align the data sending and receiving within the first resource.

[0175] Optionally, the second device does not receive or does not expect to receive the data from the first device, which can include not receiving or not expecting to receive at least one of the following: a third channel, a fourth channel. Correspondingly, the first device does not send or does not expect to send the data to the second device, which can include not sending or not expecting to send at least one of the following: the third channel, the fourth channel. The third channel is used to carry data, and the fourth channel is used to carry control information.

[0176] The third channel is used to carry data. The third channel can include a dynamically scheduled channel, or the third channel can include a periodic and / or semi-static configured channel, or the third channel can include a dynamically scheduled channel and a periodic and / or semi-static configured channel. Taking the second device as a network device and the first device as a terminal device as an example, the third channel can include a PUSCH dynamically scheduled by the network device for the terminal device through DCI (or UL Grant), and / or the third channel can include a periodic or semi-static PUSCH semi-statically 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 can include a PDSCH dynamically scheduled by the network device for the terminal device through DCI, and / or the third channel can include a periodic or semi-static PDSCH semi-statically configured by the network device for the terminal device through RRC signaling or MAC CE signaling.

[0177] For example, the method further comprises step S402, in which the first device or the second device determines a periodic channel used for the first device to send data to the second device. When there is data to be sent, the first device can send the periodic channel, and when there is no data to be sent, the first device can not send the periodic channel. Correspondingly, the second device performs blind detection on the resource position of the periodic channel to determine whether the first device has sent the periodic channel to the second device. This step can be before or after S410 or S401, and is not limited. This step is not shown in the figure. The periodic channel can be configured for the first device or the second device. In this application, the third channel can include the periodic channel. When the periodic channel is in the first resource, the first device does not send 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 in the first resource, the first device can send data to the second device on the periodic channel, and correspondingly, the second device can receive data on the periodic channel.

[0178] The fourth channel is used to carry control information. The fourth channel can be a channel transmitted on a configured periodic resource. On the periodic resource, when there is control information to be sent, the first device can send the fourth channel, and when there is no control information to be sent, the first device can not send the fourth channel. Correspondingly, the second device performs blind detection on the configured periodic resource to determine whether the first device has sent the fourth channel to the second device. The periodic resource can be configured for the first device or the second device. In this application, when the fourth channel is in the first resource, the first device does not send 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 in the first resource, the first device can send control information to the second device on the fourth channel, and correspondingly, the second device can receive control information on the fourth channel.

[0179] The control information carried by the fourth channel can be used to indicate the second device to receive or transmit data, or 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. Alternatively, the control information carried by the fourth channel can be used to indicate that the first device has data to be transmitted to the second device, or the control information carried by the fourth channel can be used to request the second device to configure resources for the first device to transmit data to the second device. For example, the second device is a network device, and the first device is a terminal device. The fourth channel can include a PUCCH used to transmit an SR, and the control information carried by the fourth channel can be the SR. For example, the second device is a terminal device, and the first device is a network device. The fourth channel can include a PDCCH used to carry a DCI, and the control information carried by the fourth channel can be the DCI.

[0180] In a possible implementation, the first device and the second device can align the receiving and transmitting of the broadcast channel, the signal for measurement, the signal for sensing, or the signal for AI in the first resource. For details, refer to the description of design one.

[0181] In a possible implementation, the first device and the second device can determine that there is no transmission from the first device to the second device in the first resource, i.e., there is no transmission of any signal from the first device to the second device. In this way, deep energy saving can be achieved.

[0182] It should be understood that design one and design two can be combined with each other. If the first device can receive and transmit the above-mentioned signals related to the second device in the first resource, and correspondingly, the second device can receive and transmit the above-mentioned signals related to the first device in the first resource, the first device can reduce the power consumption of maintaining the receiving and transmitting, and the second device can also reduce the power consumption of the receiving and transmitting, so as to achieve better energy saving effect of both ends. It should be understood that a plurality of signals are listed in design one and design two, and in the combined scheme of design one and design two, the signals in design one and the signals in design two can be the same or different.

[0183] It should be understood that the names of the above-mentioned signaling or channels (such as PDCCH, DCI, PDSCH, PUCCH, PUSCH, etc.) are only examples, and future communication systems can have other names or similar functions. The application does not make any limitation. In addition, the above-mentioned signaling or channel can be a physical layer channel, or a logical channel, or a transport channel, or a service flow, or a control flow, or a security flow, and the application does not make any limitation.

[0184] It should be understood that the first resource can be a wireless communication resource. The first resource can be a resource composed of at least one of a time domain, a frequency domain, a space domain, a code domain, or a power domain. The first resource can be continuous or discontinuous in at least one of the time domain, the frequency domain, the space domain, the code domain, or the power domain. Hereinafter, a resource position of the first resource can refer to a position of the first resource in at least one of the time domain, the frequency domain, the space domain, the code domain, or the power domain.

[0185] Optionally, the method further comprises a step S420, which is not shown in the figure.

[0186] S420: In 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 transmits or expects to transmit 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. Correspondingly, in the second resource, the second device transmits or expects to transmit 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, 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 part of the resources other than the first resource.

[0187] In this way, data, a broadcast channel, and the like can be concentrated on the second resource for transmission. For example, the second device concentrates data for transmission in the second resource after accumulating packets in the first resource, and the first device can concentrate on receiving data in the second resource. The data concentrated on receiving in the second resource can be part of the data accumulated in the first resource, or all of the data. Thus, the purpose of reducing power consumption is achieved.

[0188] For example, the first device, in the first resource, does not receive or does not expect to receive from the second device at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI; and / or, does not transmit or does not expect to transmit to the second device at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI. Optionally, the first device, in the first resource, receives or expects to receive from the second device a broadcast channel, and / or, transmits or expects to transmit to the second device a broadcast channel. Optionally, the first device, in the second resource, receives or expects to receive from the second device a broadcast channel and at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI, and / or, transmits or expects to transmit to the second device a broadcast channel and at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI. Correspondingly, the second device, in the first resource, does not transmit or does not expect to transmit to the first device at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI; and / or, does not receive or does not expect to receive from the first device at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI. Optionally, the second device, in the first resource, transmits or expects to transmit to the first device a broadcast channel, and / or, receives or expects to receive from the first device a broadcast channel. Optionally, the second device, in the second resource, transmits or expects to transmit to the first device a broadcast channel and at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI, and / or, receives or expects to receive from the first device a broadcast channel and at least one of: data, a signal for measurement, a signal for sensing, or a signal for AI.

[0189] The second resource can be indicated by the first information, or can be indicated by the second information. The first information and the second information can jointly indicate the second resource.

[0190] Optionally, the second resource can be replaced by a second timer and / or a second time window. Hereinafter, the second resource is taken as an example for description.

[0191] The second information can be information transmitted by the first device to the second device, or can be information transmitted by the second device to the first device. Optionally, the method further comprises step S403 or S404, which are not shown in the figure.

[0192] S403: The second device transmits the second information, and correspondingly, the first device receives the second information, the second information being used to determine the second resource.

[0193] S404: The first device sends the second information, and correspondingly, the second device receives the second information, the second information being used to determine the second resource.

[0194] Optionally, the first device receives or expects to receive data from the second device, which can include that the first device receives or expects to receive at least one of the first channel and the second channel.

[0195] Optionally, the first device sends or expects to send data to the second device, which can include that the first device sends or expects to send at least one of the third channel and the fourth channel.

[0196] Optionally, the second device sends or expects to send data to the first device, which can include that the second device sends or expects to send at least one of the first channel and the second channel.

[0197] Optionally, the second device receives or expects to receive data from the first device, which can include that the second device receives or expects to receive at least one of the third channel and the fourth channel.

[0198] It can be understood that the second resource and the first resource are corresponding, and the description of the first channel, the second channel, the third channel, the fourth channel and the above-mentioned signals can refer to the description in step S410.

[0199] As described above, the first information is information sent by the second device to the first device, and the first information is used to determine the first resource. In this way, the first device can determine the position of the first resource according to the first information. Optionally, the method further includes second information, which can be information sent by the first device to the second device, or information sent by the second device to the first device, and the second information is used to determine the second resource. In this way, the first device can determine the position of the second resource according to the second information. In a possible way, the first resource and the second resource have a specific positional relationship, so that the position of the first resource can be deduced through the position of the second resource, that is, the first information indicates the position of the second resource, and the first device can determine the position of the first resource according to the positional relationship between the position of the second resource and the position of the first resource.

[0200] In a possible embodiment, the first information or the second information can be information sent by the network device to the terminal device. Optionally, the first information or the second information can be carried in RRC signaling, MAC CE signaling, a channel or a signal (for example, PDCCH, a wake-up signal, or newly added DCI information) of a physical layer protocol used to carry control information. In another possible embodiment, the first information or the second information can be information sent by the terminal device to the network device. Optionally, the first information or the second information can be carried in a channel or a signal (for example, PUCCH, SR, or newly added UCI information) of a physical layer protocol used to carry control information.

[0201] The first information and the second information can be different information or the same information. The first information and the second information can also have a containing relationship, 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 can be carried in different signaling and / or information element and / or field.

[0202] The first information or the second information is specifically described below.

[0203] Case 1: The first information indicates a resource location of the first resource.

[0204] In case 1, the resource location of the first resource can be directly indicated by the first information, that is, explicit indication, or the resource location of the first resource can be indicated by the first information in combination with at least one of a pre-defined parameter, a pre-defined rule, or a parameter carried in other signaling.

[0205] For example, the first information can indicate at least one of a time length of the first resource, a start time of the first resource, or an end time of the first resource. The start time or the end time of the first resource can be derived according to a resource location of a resource carrying the first information. For example, the first information can be carried in DCI or PDCCH, and the start time or the end time of the first resource can be derived according to a time location of the DCI or the PDCCH, for example, a time after a first time length of an end time of the DCI or the PDCCH is the start time of the first resource.

[0206] Case 2: The first information indicates a repetition period and a resource location of the first resource.

[0207] In case 2, the repetition period and the resource location of the first resource can be directly indicated by the first information, i.e., explicit indication, or can be indicated by the first information in combination with at least one of the pre-defined parameters, the pre-defined rules or the parameters carried in other signaling. The parameters for indicating the repetition period and the resource location can be in the same signaling and / or the same information element (IE), or can be in different signaling and / or different IEs, without limitation.

[0208] For example, the first information can indicate at least one of the following: the time length 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 in the repetition period.

[0209] FIG. 5 is a schematic diagram of the first resource according to an embodiment of the present application. As shown in FIG. 5, the first resource is a periodically repeated resource. When a data packet arrives at the network device, the network device delays sending the data packet, i.e., packet accumulation, in the first resource. In the resource outside the first resource, the network device sends the data packet to the terminal device, which can include the data packet arriving in the first resource. In the resource outside the first resource, the network device can send the data packet to the terminal device by dynamic scheduling, or can send the data packet to the terminal device by semi-statically configured resource. The specific scheduling manner is not limited in the present application.

[0210] FIG. 6 is a schematic diagram of the first resource according to an embodiment of the present application. As shown in FIG. 6, the first resource is a periodically repeated resource. When a data packet arrives at the terminal device, the terminal device delays sending the data packet or the terminal device delays sending the information (e.g., SR) indicating that the terminal device has data packets to send, i.e., packet accumulation, in the first resource. In the resource outside the first resource, the terminal device can send the data packet to the network device, which can include the data packet arriving in the first resource. In the resource outside the first resource, the terminal device can send the data packet to the network device by semi-statically configured resource, or can first send the information (e.g., SR) indicating that the terminal device has data packets to send to the network device, and then send the data packet according to the scheduling information of the network device. The specific scheduling manner is not limited in the present application.

[0211] In the embodiments shown in FIG. 5 or FIG. 6, the second resource can be understood as a dynamically scheduled resource for transmitting the data packet, or can be understood as a semi-statically configured resource for transmitting the data packet, or can be understood as all the resources outside the first resource, without limitation.

[0212] Case 3: The first information is periodic information, and the first information is used 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.

[0213] In case 3, a fixed repetition period of receiving the first information can be agreed, so that the first device periodically detects the first information to determine the configuration of the first resource in the current period. The repetition period of the first information can be configured by the first device or configured by the second device. In case 3, whether the first resource exists in the current period and / or the resource location of the first resource in the current period can be directly indicated by the first information; or, at least one of the parameters in the first information, the pre-defined parameters, the pre-defined rules or the parameters carried in other signaling can be used to indicate whether the first resource exists in the current period and / or the resource location of the first resource in the current period. The first resource in one period can be one or more, or it can be understood that the first resource in one period can be continuous or discontinuous.

[0214] In one possible embodiment, the location of the first resource in each period is the same. Optionally, the first information can only indicate whether the first resource exists in the current period. In another possible embodiment, the location of the first resource in each period can be different. Optionally, the first information can indicate the location of the first resource in the current period to obtain greater configuration flexibility.

[0215] The following takes 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 time length of the first resource, the start time of the first resource, the end time of the first resource, the offset value of the first resource in the repetition period of the first information.

[0216] FIG. 7 is a schematic diagram of a first resource according to an embodiment of the present application. As shown in FIG. 7, taking the network device sending a data packet to the terminal device as an example, the first information can be the information sent by the network device to the terminal device, and the first information can also be the information sent by the terminal device to the network device. The first information indicates whether the first resource exists in the current period and / or the location of the first resource. In the first resource, when a data packet arrives at the network device, the network device will delay sending the data packet, i.e., packet accumulation. In the resource outside the first resource, the network device sends the data packet to the terminal device, which can include the data packet arriving in the first resource. In the resource outside the first resource, the network device can send the data packet to the terminal device by dynamic scheduling or by semi-statically configured resources, and the specific scheduling manner is not limited in the present application.

[0217] FIG. 8 is a schematic diagram of a first resource according to an embodiment of the present application. As shown in FIG. 8, taking the terminal device sending a data packet to the network device as an example, the first information can be information sent by the network device to the terminal device, or the first information can be information sent by the terminal device to the network device. In the first resource, when a data packet arrives at the terminal device, the terminal device delays sending the data packet or the terminal device delays sending information (such as an SR) indicating that the terminal device has a data packet to send, that is, the terminal device performs packet accumulation. In a resource other than the first resource, the terminal device can send a data packet to the network device, which can include a data packet that arrives in the first resource. In the resource other than the first resource, the terminal device can send a data packet to the network device through a semi-statically configured resource, or the terminal device can first send information (such as an SR) indicating that the terminal device has a data packet to send to the network device, and then send the data packet according to the scheduling information of the network device. The present application does not limit the specific scheduling mode.

[0218] In the embodiments shown in FIG. 7 or FIG. 8, the second resource can be understood as a resource for dynamic scheduling of a data packet, or understood as a semi-statically configured resource for transmission of a data packet, or understood as all resources other than the first resource, without limitation.

[0219] Case 4: The second information indicates the resource location of the second resource.

[0220] The indication mode of case 4 is similar to that of case 1, and the description in case 1 can be referred to, with the first information replaced by the second information and the first resource replaced by the second resource.

[0221] Case 5: The second information indicates the repetition period and the resource location of the second resource.

[0222] The indication mode of case 5 is similar to that of case 2, and the description in case 2 can be referred to, with the first information replaced by the second information and the first resource replaced by the second resource.

[0223] Case 6: The second information is periodic information, and the second information is used to indicate whether the second resource exists in the current period and / or indicate the resource location of the second resource in the current period.

[0224] The indication mode of case 6 is similar to that of case 3, and the description in case 3 can be referred to, with the first information replaced by the second information and the first resource replaced by the second resource.

[0225] Cases 1-3 and cases 4-6 described above can be combined with each other.

[0226] Case 7: The first information indicates the repetition period and the resource location of the second resource.

[0227] The first information in case 7 indicates the repetition period and resource location of the second resource, which is similar to the first information indicating the repetition period and resource location of the first resource in case 2. The description in case 2 can be referred to, and the first resource is replaced by the second resource. In a case where the repetition period and resource location of the second resource are determined through the first information, the repetition period and resource location of the first resource can be determined according to a predefined rule, for example, the first resource is all resources other than the second resource, or the first resource is a resource having a specific location relationship with the second resource.

[0228] In a possible embodiment, the second resource can be a periodic resource indicated by a PDCCH search space for packet accumulation or for energy saving, and the terminal device blind detects downlink control information on the resource. In another possible embodiment, the second resource can be a periodic resource of a PDCCH candidate where DCI scrambled by an RNTI for packet accumulation or for energy saving is located, and the terminal device blind detects downlink control information scrambled by the RNTI for packet accumulation or for energy saving on the resource. In another possible embodiment, the second resource can be a semi-statically configured periodic resource for transmitting a data packet.

[0229] For example, the start time or end time of the first resource in a period can be derived according to the resource location of the second resource. For example, the start time or end time of the first resource in a period can be a time after a first time length of the end time of the second resource in the period.

[0230] 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 indicate the resource location of the second resource in the current period, and the first resource is a resource other than the second resource in the current period.

[0231] The indication manner of the first information in case 8 is similar to that in case 3, and the description in case 3 can be referred to, and the first resource is replaced by the second resource. In a case where 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 a predefined rule, for example, the first resource is all resources other than the second resource in the current period, or the first resource is a resource having a specific location relationship with the second resource.

[0232] In a possible embodiment, the second resource can be a resource location for transmitting a data packet in the current period scheduled or indicated by the first information, or the second resource can be a semi-statically configured resource for transmitting a data packet in the current period activated by the first information.

[0233] For example, the start time of the first resource in a period can be derived according to the resource position of the second resource. For example, the start time of the first resource in a period can be the end time of the second resource in the period or a time after the end time of the second resource by a first time length.

[0234] Optionally, in the above cases 1-8, 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 according to the service requirement of one or more of the data, the broadcast channel, the signal for measurement, the signal for sensing, or the signal for AI, for example, the repetition period is less than or equal to a threshold of the service latency.

[0235] Optionally, the position of the first information or the first resource is related to the resource position corresponding to the MIB, the SIB1, the OSI, or the Paging.

[0236] Optionally, the design one and the design two can be combined with each other. The first device can not receive and send the above-mentioned signals related to the second device in the first resource, and correspondingly, the second device can not receive and send the above-mentioned signals related to the first device in the first resource. FIG. 9 and FIG. 10 are schematic diagrams of a first resource provided by an embodiment of the present application, in which the network device and the terminal device send data packets to each other. The specific indication manner of the first resource and the second resource can be referred to the above cases 1-8, and will not be described herein.

[0237] As shown in FIG. 9, the first resource is a periodically repeated resource. In the first resource, when a data packet arrives at the network device or the terminal device, the network device delays sending the data packet, the terminal device delays sending the data packet, or the terminal device delays sending information (such as an SR) indicating that the terminal device has a data packet to send, that is, packet accumulation is performed. In a resource other than the first resource, the network device sends a data packet to the terminal device and / or the terminal device sends a data packet to the network device, which can include the data packet arriving in the first resource. In the resource other than the first resource, the data packet can be sent by a dynamic scheduling manner or by a semi-statically configured resource, and the specific scheduling manner is not limited in the present application. For reference, see cases 2 and 7.

[0238] The first information can be information sent by the network device to the terminal device, or the first information can be information sent by the terminal device to the network device. The first information indicates whether the first resource exists in the current period and / or the location of the first resource, or the first information indicates whether the 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. In the first resource, when a data packet arrives at the network device or the terminal device, the network device delays sending the data packet, the terminal device delays sending the data packet or the terminal device delays sending information (such as an SR) indicating that the terminal device has a data packet to send, that is, the terminal device performs packet accumulation. In the resource outside the first resource, the network device sends a data packet to the terminal device and / or the terminal device sends a data packet to the network device, which can include a data packet arriving in the first resource. In the resource outside the first resource, the data packet can be sent by dynamic scheduling or can be sent by semi-statically configured resource, and the specific scheduling manner is not limited in the application. Referring to case 3 and case 8.

[0239] Optionally, the method further includes step S430, which is not shown in the figure.

[0240] S430: The first device sends third information, and the second device receives the third information accordingly.

[0241] Optionally, the third information is used by the second device to determine the first information. Alternatively, the first resource and / or the second resource meets the requirement of the third information. Alternatively, the third information is used to determine whether to start the packet accumulation function. Alternatively, the third information is used to determine whether to activate the first resource and / or the second resource.

[0242] In this way, the first device can send its own information to the second device through the third information, for negotiating the first resource. For example, the first device sends its own packet accumulation time to the second device, and then the second device can determine the resource location of the first resource according to the information. In this way, the resource location of the first resource that is more suitable for the double-end situation can be negotiated and determined, so as to achieve a better energy saving effect.

[0243] The third information can include service characteristic information of the first device. For example, the first device can be a terminal device, and the second device can be a network device. The service characteristic information of the first device can be service characteristic information of the terminal device. In this way, by transmitting the service characteristic information (for example, the terminal reports the service characteristic information, and the base station obtains the service characteristic information), the packet accumulation scheduling can be more accurately performed without affecting the service performance.

[0244] In a possible embodiment, the third information comprises at least one of the following: a first packet delay, a packet average interval, a service packet period, a service statistical feature, a service arrival delay, a number of service packets to be transmitted, a size of service packets to be transmitted, a size of all service packets to be transmitted, a size of all service packets, a service deterministic experience index (e.g., an SLA index), a quality of service (QoS) index of the service (e.g., one or more of the following: priority, packet delay, packet error rate), a quality of experience (QoE) index of the service (e.g., one or more of the following: lag, definition, user experience score, video mean opinion score (VMOS) (an example of VMOS, the higher the score, the better the experience)).

[0245] Optionally, the third information is carried in RRC, MAC, UCI, or the like signaling.

[0246] In the above method, the first resource can be used for sleeping, energy saving, packet accumulation, or not performing signal transmission in the first resource. A device supporting the above method of sleeping, energy saving, packet accumulation, or not performing signal transmission in the first resource can be referred to as supporting a packet accumulation capability, a packet accumulation transmission capability, or the like.

The two can be replaced with each other, and will not be described one by one in the following.

[0249] Optionally, the method further comprises enabling the packet accumulation function when the first condition is satisfied. Or, the method further comprises activating the first resource and / or the second resource when the first condition is satisfied.

[0250] The first condition can comprise one or more of the following:

[0251] a terminal moving speed is greater than a certain speed;

[0252] a terminal data rate is less than a certain threshold;

[0253] a base station is lightly loaded;

[0254] a base station resource utilization is less than a certain threshold;

[0255] a base station is idle (e.g. at night, late night, etc.);

[0256] a service requirement rate or latency, or a Qos flow, or a SLA index (Service Level Agreement) satisfies a certain numerical condition or a certain threshold;

[0257] terminal and / or base station service characteristic information satisfies a certain threshold;

[0259] enable an energy saving mode (terminal energy saving, base station energy saving, dual-end energy saving mode).

[0260] The threshold or a certain specific numerical value can be determined by network configuration or protocol predefinition.

[0261] In this way, the packet accumulation function can be enabled at an appropriate time according to the first condition. For example, based on service characteristic information to determine whether to enable the packet accumulation function, packet accumulation scheduling can be more accurate and does not affect service performance.

[0262] Optionally, based on the third information described in S430, the service characteristic information of the terminal and / or the base station related to the first condition can be determined, or the following at least one of the terminal and / or the base station or the index value determined based on the following at least one of the terminal and / or the base station: first packet delay, packet average interval, service packet period, service statistical characteristics, service arrival delay, service pending packet number, service pending packet size, all pending packet size, all service packet size, service deterministic experience index (such as SLA index), quality of service (QoS) index of the service (such as one or more of the following: priority, packet delay, packet error rate), quality of experience (QoE) index of the service (such as one or more of the following: lag, clarity, user experience score, video mean opinion score (VMOS) (exemplary VMOS, the higher the score, the better the experience)).

[0263] It can be understood that the above-mentioned starting the packet accumulation function when the first condition is met can be starting by the terminal, starting by the base station, or starting by the terminal and the base station. In an embodiment, when the terminal and / or the base station determines that the first condition is met, the packet accumulation function can be started according to a predefined fixed rule, for example, starting the packet accumulation function at a time when the first condition is determined to be met or at a certain time after the time when the first condition is determined to be met. In another embodiment, when the terminal and / or the base station determines that the first condition is met, information can be sent to the opposite side, and the information is used to request to start the packet accumulation function (or referred to as used to request scheduling resources, used to request the first resource and / or the second resource, used to request to activate the first resource and / or the second resource, used to request the first information, or used to request scheduling resources). Taking the first device as a terminal device and the second device as a network device as an example, when the first condition is met, the terminal device can send the information.
