Communication method, and apparatus

Abstract

A communication method, and an apparatus, which are capable of reducing the power consumption of control information receivers and transmitters. In the method, a second communication apparatus transmits first information on a first resource, the interval between the first resource and a third resource used for transmitting periodic information being less than a first threshold, the first information indicating the operating state (for example, whether to detect a PDCCH or detect paging) of a first communication apparatus on a second resource; and because of the very small interval between the first resource and the third resource, the second communication apparatus may transmit the first information and the periodic information within one wake-up state, thus reducing the power consumed by the second communication apparatus for transmitting control information. That is, the transmission of the first information has a lower impact on the second communication apparatus, the probability of the second communication apparatus transmitting the first information increases, and the probability of the first communication apparatus receiving the first information also increases, such that the power consumption of the first communication apparatus caused by failure in receiving the first information is reduced.

Description

Communication method and apparatus

[0001] The present application claims priority from the Chinese patent application No. 202410826258.0 filed on June 24, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

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

[0003] In a mobile communication system, downlink control information (DCI) is carried by a physical downlink control channel (PDCCH) between a terminal and an access network device, and the DCI can be used to schedule data transmission of the terminal. Since the PDCCH can carry multiple DCIs with different formats, and the DCI format of a certain transmission is unknown to the terminal, the terminal needs to determine the time-frequency resources occupied by the PDCCH and the format of the DCI through PDCCH blind detection.

[0004] Since the arrival time of data packets is uncertain, the access network device usually configures the terminal to perform PDCCH blind detection in each time slot. However, for a terminal, frequent service scheduling does not occur in most cases. Therefore, the NR communication system introduces a connected discontinuous reception (C-DRX) mode in the connected state, so that the terminal periodically enters a sleep state (also known as a sleep period) in the connected state, and determines whether to perform PDCCH blind detection according to a wake-up signal (WUS).

[0005] However, when performing PDCCH blind detection based on the current C-DRX mode and WUS signal, the terminal and the access network device still have high power consumption. SUMMARY

[0006] The present application provides a communication method and apparatus, which effectively reduces the power consumption of a first communication device and a second communication device in the process of transmitting and receiving control information, and achieves power consumption balance of both sides of the control information transmission and reception.

[0007] In a first aspect, a communication method is provided. The method can be performed by a first communication device, a module (e.g., a processor, a chip, or a chip system) applied to the first communication device, or a logic node, a logic module, or software that can implement all or part of the functions of the first communication device. The first communication device can be a terminal. The method includes: receiving first information on a first resource, the first information being used to indicate a state of at least one first communication device on a second resource; wherein the state includes one or more of the following: whether a downlink control channel is detected, whether a paging is detected, whether an awake state is in, or whether a sleep state is in; a time interval between the first resource and a third resource is less than or equal to a first threshold, the third resource being used to carry periodic information; and determining the state of the first communication device on the second resource according to the first information.

[0008] Based on the scheme, the second communication device can complete the transmission of the first information and the periodic information when entering the active state or the awake state once, without entering the awake state or the active state multiple times, thereby reducing the number of times of activating / awaking in the process of transmitting the control information by the second communication device, and reducing the power consumption of the second communication device. Since the transmission of the first information can reduce the power consumption of the second communication device compared to the transmission of the current WUS, the second communication device has less impact, and thus the probability of the second communication device transmitting the first information is greater than the probability of the second communication device transmitting the WUS, the probability of the first communication device obtaining the first information is greater than the probability of the first communication device obtaining the WUS, thereby reducing the power consumption caused by the first communication device entering the awake state or performing invalid PDCCH detection without entering the awake state or detecting the PDCCH due to not receiving the control information (the first information or the WUS), and achieving the power consumption balance of the transmitting end and the receiving end.

[0009] In a possible design, the first information is used to indicate the second resource corresponding to the first communication device and the state of the first communication device on the second resource.

[0010] Based on the scheme, the control of each first communication device can be relatively independent, thereby improving the flexibility of the control and scheduling of the first communication devices.

[0011] In a possible design, the first communication device detects the periodic information on the third resource. Optionally, the first communication device detects the periodic information on all resources included in the third resource. Alternatively, the first communication device detects the periodic information on part of the resources included in the third resource. Optionally, the first communication device receives the periodic information on all resources included in the third resource. Alternatively, the first communication device receives the periodic information on part of the resources included in the third resource.

[0012] In a possible design, the first threshold is predefined; or, the method further includes: sending second information, where the second information is used to indicate a time interval between the first resource and the third resource supported by the first communication device.

[0013] Based on this scheme, the first threshold is set according to the time interval that can be supported by the first communication device, which facilitates meeting the power consumption requirement of the first communication device through the setting of the first threshold.

[0014] In a possible design, the first threshold is 0, and the first resource and the third resource are adjacent in time.

[0015] Based on this scheme, the first information can be sent immediately or synchronously with the periodic information, which further reduces the impact of the sending of the first information on the power consumption of the second communication device, and improves the sending probability of the first information.

[0016] In a possible design, the time interval between the first resource and the second resource is less than or equal to a second threshold.

[0017] Based on this scheme, while ensuring that there is a sufficient time interval between the first resource and the second resource, the time interval is prevented from being too large, which causes a large reaction time delay of the first communication device to the indication of the first information.

[0018] In a possible design, the communication method further includes: sending third information, where the third information is used to indicate a time interval between the first resource and the second resource supported by the first communication device.

[0019] In a possible design, the first resource and the third resource are both time resources.

[0020] In a possible design, the second resource is a time resource, a time length of the second resource is T, and T is greater than 0; or, the second resource is a frequency resource; or, the second resource is a time-frequency resource.

[0021] In a possible design, the communication method further includes: sending fourth information, where the fourth information is used to indicate at least one of the following supported by the first communication device: a time length of the second resource, a minimum time length of the second resource, or a maximum time length of the second resource.

[0022] Based on this scheme, it is convenient to accurately determine the second resource corresponding to each first communication device, which facilitates improving the flexibility and accuracy of control and scheduling of the first communication device.

[0023] In one possible design, the first information indicates that the at least one first communication device receives control information on the second resource when the state of the at least one first communication device on the second resource is the first state; and / or, the first information indicates that the at least one first communication device does not receive control information on the second resource when the state of the at least one first communication device on the second resource is the second state; where the control information includes at least one of: downlink control information, paging information, or sensing information.

[0024] Based on this scheme, the first communication device can adjust the control information reception state of the device on the second resource according to the first information, and avoid the first communication device from generating meaningless power consumption.

[0026] In one possible design, the first information is used to indicate the state of the at least one first communication device on the second resource, including: the first information is used to indicate the state of N first communication devices on the second resource, where N is an integer greater than 1; the N first communication devices satisfy one or more of the following: the N first communication devices are associated with a same beam, the N first communication devices are associated with a same second resource, the N first communication devices are associated with a same SSB index, or the N first communication devices are associated with a same group number.

[0027] Based on this scheme, one first information is used to indicate the state of N first communication devices on the second resource, which significantly reduces the signaling overhead for the second communication device to control the state of multiple first communication devices on the second resource, and is beneficial to reduce the power consumption of the second communication device.

[0028] In one possible design, the first information includes at least N bits, each of the N bits being used to indicate the state of one of the N first communication devices on the second resource; or the first information includes at least 1 bit, the 1 bit being used to indicate the state of the N first communication devices on the second resource.

[0029] Based on this scheme, the first information can accurately control the state of each of the N first communication devices on the second resource, and thus greatly improves the control flexibility of the first communication device.

[0080] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, first, a brief introduction of the related technologies of the present application is given as follows.

[0081] 1. New radio (NR) technology:

[0082] The fifth-generation (5G) mobile communication technology NR is a brand-new air interface design based on orthogonal frequency division multiplexing (OFDM), and is also the basis of the next generation of cellular communication technology.

[0083] In NR, the basic unit in the frequency domain is a subcarrier, and the subcarrier spacing (SCS) can be 15 kHz, 30 kHz, etc. In the NR physical layer, the unit of uplink or downlink frequency domain resources is a resource block (RB), and each RB is composed of 12 consecutive subcarriers in the frequency domain.

[0084] In the NR communication system, the terminal accesses the network in the form of requesting to establish a connection (generally referred to as random access), and the cell search in the terminal access network process mainly includes two cases. One case is the initial cell search performed by the terminal that has not accessed the network after entering the area covered by the communication system. The other case is the cell search performed by the terminal in the idle state / activation state during the cell switching or cell reselection process. Both of these two cell searches need to rely on synchronization signals and PBCH blocks (SSB) to achieve.

[0085] 2. SSB:

[0086] The SSB includes a synchronization signal (SS) and a physical broadcast channel (PBCH), and the synchronization signal includes two parts: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0087] The SSS and the PSS are mainly used for the terminal to perform transceiving synchronization with the access network device and determine a physical cell identity (PCI); and the PBCH is mainly used to carry a master information block (MIB), which includes a system frame number, a cell barring identity, and a system information block (SIB) parameter set and other information, for the terminal to determine other system information broadcast by the NR communication system.

[0088] In order to enable the terminal to find a cell to camp on after turning on and entering a region covered by the communication system, or to find a new cell after moving in the communication system, each cell in the communication system periodically transmits an SSB. In the process of cell search in the communication system, the terminal first performs PSS search, and after detecting the PSS, the terminal determines the period of the PSS and the time domain position of the subsequent PSS; then the terminal can determine the transmission timing of the SSS according to the PSS, and determine the PCI of the cell by detecting the SSS, to complete transceiving synchronization (which can also be understood as clock and transceiving frequency synchronization) with the access network device; finally, the terminal decodes the data part of the PBCH according to the parameter information obtained from the PSS and the SSS, to obtain the remaining configuration information and channel state information of the communication system.

[0089] The structure of the SSB can refer to FIG. 1. In the time domain, one SSB occupies 4 consecutive OFDM symbols, which are sequentially numbered 0 to 3 in the order of time increase. In the frequency domain, one SSB occupies 240 consecutive subcarriers (i.e., 20 RBs), which are sequentially numbered 0 to 239 in the order of frequency increase. It should be noted that the numbering of the 4 OFDM symbols is relative to the numbering of the starting position of the SSB in the time domain, and the numbering of the 240 subcarriers is relative to the numbering of the starting position of the SSB in the frequency domain.

[0090] 3. Synchronization signal burst set:

[0091] A set of all SSBs adopted by a cell or an access network device (e.g., a base station) in a beam sweeping procedure is referred to as a synchronization signal burst set (may also be referred to as an SSB burst set).

[0092] More antennas are used in a communication system to ensure signal quality for coverage enhancement, but using more antennas causes most of the transmission energy to be concentrated in a very narrow area, i.e., the antenna radiates a very narrow narrow beam, and a single narrow beam is difficult to cover the entire cell. Therefore, the access network device in the communication system can transmit multiple SSBs through beam sweeping to cover the entire cell, i.e., different SSBs are transmitted on different beams in a time division multiplexing manner to cover the entire cell.

[0093] For example, as shown in FIG. 2, the access network device can transmit a beam carrying SSB0 to cover one direction at time 0, transmit a beam carrying SSB1 to cover another direction at time 1, and so on, until transmitting a beam carrying SSBn to cover the nth direction at time n, thereby covering the entire cell through multiple different beams transmitted at multiple different times. Wherein n is a positive integer greater than 2.

[0094] Referring to FIG. 3, in a synchronization signal burst set period, the SSB beam sweeping of a synchronization signal burst set is concentrated in the same half frame, the maximum number of SSBs included in the synchronization signal burst set is determined by the carrier frequency / band, and the starting time domain symbol of each SSB is determined by the subcarrier spacing and the carrier frequency / band. For example, in case A, the frequency band is below 3 GHz, the subcarrier spacing is 15 kHz, and a synchronization signal burst set can have at most 4 SSBs, i.e., at most 4 beams can be swept; the frequency band is between 3 GHz and 6 GHz, the subcarrier spacing is 15 kHz, and a synchronization signal burst set can have at most 8 SSBs, i.e., at most 8 beams can be swept. In case A, the frequency band is below 3 GHz, the subcarrier spacing is 15 kHz, and in the case of a synchronization signal burst set containing 4 SSBs, the starting time domain symbols of the 4 SSBs are evenly distributed on the first quarter of the frame; in case B, the frequency band is below 3 GHz, the subcarrier spacing is 30 kHz, and a synchronization signal burst set can have at most 4 SSBs, i.e., at most 4 beams can be swept, and in the case of a synchronization signal burst set containing 4 SSBs, the starting time domain symbols of the 4 SSBs are evenly distributed on the first eighth of the frame. In case B, the frequency band is between 3 GHz and 6 GHz, the subcarrier spacing is 30 kHz, and a synchronization signal burst set can have at most 8 SSBs, i.e., at most 8 beams can be swept, and in the case of a synchronization signal burst set containing 8 SSBs, the starting time domain symbols of the 8 SSBs are evenly distributed on the first eighth of the frame.

[0095] The time for the access network device to complete one SSB beam sweeping can be referred to as the time for transmitting one synchronization signal burst set, and the beam sweeping period of the SSB can also be considered as the transmission period of the synchronization signal burst set. The transmission period of one synchronization signal burst set can be flexibly set between 5 milliseconds (ms) and 160 ms. Since the access time of the terminal is uncertain, in order to ensure that the terminal can quickly find a cell after starting up or during cell switching / reselection, the default transmission period of one synchronization signal burst set is 20 ms. That is, the SSB is a constant-on signal for the access network device, which has a great impact on the power consumption of the base station.

[0096] 4. Physical downlink control channel (PDCCH) blind detection:

[0097] The PDCCH is used to carry scheduling and other control information, such as downlink control information (DCI). The DCI has multiple different formats, and the format of the DCI of a transmission is unknown to the terminal during the interaction between the terminal and the access network device, that is, the terminal does not know the format of the DCI of a transmission.

[0098] Therefore, the terminal can determine the format of the DCI of a transmission through PDCCH blind detection, that is, during a transmission, the terminal can use one or more search spaces (SSs) to decode the PDCCH on the control resource set (CORESET) to determine the possible time-frequency resource size and location of the PDCCH, thereby determining the format of the DCI, and then decoding the content of the DCI of the transmission.

[0099] Among them, the time-frequency resource of the CORESET is a shared resource, and the size and location of the CORESET are semi-statically configured by the network, that is, for the terminal, the PDCCH occupies a shared resource, so the terminal may detect the DCI of the terminal on the CORESET through PDCCH blind detection, or may find that there is no DCI of the terminal after detecting the PDCCH.

[0100] Among them, the SS is a group of candidate control channels with the same aggregation level. In order to enable the terminal to detect the DCI on the possible time-frequency resource as soon as possible, a set of candidate PDCCH candidates (PDCCH Candidates) is defined in advance in the CORESET through various aggregation levels, that is, one or more SSs are defined.

[0101] For the access network device, the arrival time of the data packet to be sent to each terminal is uncertain, and the access network device needs to arrange and schedule all the accessed terminals, therefore, in order to realize the maximum scheduling flexibility, the access network device usually configures the accessed terminals to perform PDCCH blind detection in each time slot, that is, the accessed terminals detect PDCCH in each time slot, and the detection period of PDCCH is one time slot. For a specific terminal, most of the time, the terminal will not have frequent service scheduling, therefore, most of the PDCCH detection of the terminal is invalid, and the invalid PDCCH detection will cause waste of terminal power consumption.

[0102] 5. Connected discontinuous reception (C-DRX) in connected state:

[0103] In order to reduce the power consumption of the UE, the NR system introduces C-DRX. In the C-DRX mode, the terminal can periodically enter a sleep state (also called sleep period) and an active state (also called active period or On duration).

[0104] Referring to FIG. 4, a DRX cycle includes a sleep period and an On duration, in the sleep period, the terminal is in a sleep state, the receiver is turned off, and the detection of PDCCH is not performed; in the On duration, the terminal is in an active state, the receiver is turned on, and the detection of PDCCH is performed according to the configuration of the access network device, the periodic sleep reduces the number of invalid PDCCH detections of the terminal, thereby reducing the power consumption of the terminal.

[0105] However, in the case that the traffic of the terminal is small, the scheduling probability of the terminal is low, if the terminal wakes up in each DRX cycle, that is, detects PDCCH in the On duration in each DRX cycle, the terminal will still perform multiple invalid PDCCH detections, and the power consumption of the terminal is still wasted.

[0106] Therefore, the NR system introduces a wake-up signal (WUS) to control the state of the terminal in the C-DRX mode. The WUS is a special PDCCH, which is used to indicate whether the terminal needs to detect PDCCH in the next On duration. The WUS can be carried by a common DCI (DCI format 2-6). As a special PDCCH, the WUS will affect the power consumption of the access network device, and has a great impact on the access network device, therefore, the access network device can not send the WUS, and thus cannot further reduce the power consumption of the terminal.

[0107] That is, in the current PDCCH detection scheme, if the access network device does not send the WUS in order to save power consumption, the terminal will perform a large number of invalid PDCCH detections in the active period of the DRX, resulting in a large waste of power consumption of the terminal. In order to reduce the power consumption of the terminal, it is easy to cause the power consumption of the access network device to be obviously improved, and the power consumption of the terminal and the access network device is difficult to balance.

[0108] Based on this, the present application provides a communication method, a second communication device sends first information on a first resource and sends periodic information on a third resource, the time interval between the first resource and the third resource is less than a first threshold, and the first information is used to indicate the state of at least one first communication device on a second resource, such as whether to detect a downlink control channel, whether to detect a paging, whether to be in a wake-up state or whether to be in a sleep state. The first communication device determines the state of the first communication device on the second resource according to the first information received on the first resource. The time interval between the first resource and the third resource carrying the periodic information is less than the first threshold, so that the transmission interval between the first information and the periodic information is extremely short or even can be transmitted at the same time. Therefore, the second communication device can complete the transmission of the first information and the periodic information when entering an active state or a wake-up state, without the need to enter the wake-up state or the active state multiple times, thereby reducing the number of activations / wake-ups in the process of transmitting control information by the second communication device, thereby reducing the power consumption of the second communication device. In addition, since the transmission of the first information can reduce the power consumption of the second communication device compared to the transmission of the current WUS, the impact on the second communication device is small, therefore, the probability of the second communication device transmitting the first information is greater than the probability of the second communication device transmitting the WUS, the probability of the first communication device obtaining the first information is greater than the probability of the first communication device obtaining the WUS, thereby reducing the power consumption caused by the first communication device entering the wake-up state or performing invalid PDCCH detection without entering the wake-up state or detecting the PDCCH due to not receiving the control information (the first information or the WUS), thereby reducing the power consumption of the first communication device and achieving power consumption balance between the transmitting end and the receiving end.

[0109] The technical scheme of the embodiment of the present application can be applied to various communication systems, which can be a third generation partnership project (3GPP) communication system, such as a long term evolution (LTE) system, a fourth generation (4G) system, a NR system, a 5G system, a system of mixed networking of LTE and 5G, a non-terrestrial network (NTN), or other future communication systems.

For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a radio frequency remote unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0122] The communication method provided by the embodiments of the present application will be described below by taking the communication system shown in FIG. 5 as an example, taking the first communication device as a terminal, and taking the second communication device as an access network device, and taking the access network device and the terminal as an example. It should be noted that in the embodiments described below, the names of messages between the terminal and the access network device, the names of parameters, or the names of information, etc. are only examples, and in other embodiments, they can also be other names, and the method provided by the present application does not make a specific limitation on this.

[0123] It can be understood that the first communication device and the second communication device in the embodiments of the present application can perform part or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also perform other operations or various modifications of the operations. In addition, each step can be performed in a different order according to the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are performed.

[0124] It can be understood that the access network device and the terminal are taken as examples in the present application to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the method performed by the access network device in the present application can also be performed by a module (such as a chip, a chip system, or a processor) applied to the access network device, and can also be implemented by a logic node, a logic module or software capable of realizing all or part of the functions of the access network device; the method performed by the terminal in the present application can also be performed by a module (such as a chip, a chip system, or a processor) applied to the terminal, and can also be implemented by a logic node, a logic module or software capable of realizing all or part of the functions of the terminal.

[0125] In addition, "sending information" in the present application can be understood as one device sending information to another device, or can also be understood as one logical module in a device sending information to another logical module. For example, "the access network device sending information" can be understood as the access network device sending information to another device (such as a terminal), or can be understood as a logical module 1 (such as a processing module) in the access network device sending information to a logical module 2 (such as a transceiver module) in the access network device.

[0126] "Receiving information" in the present application can be understood as one device receiving information from another device, or can also be understood as one logical module in a device receiving information from another logical module. For example, "the terminal receiving information" can be understood as the terminal receiving information from another device (such as an access network device), or can be understood as a logical module 1 (such as a processing module) in the terminal receiving information from a logical module 2 (such as a transceiver module) in the terminal.

[0127] In the present application, "sending information to (for example, a terminal)" or related illustrations in the drawings can be understood as that the destination of the information is the terminal. It can include directly or indirectly sending information to the terminal. "Receiving information from (for example, an access network device)" or "receiving information from (for example, an access network device)" or "receiving information sent by (for example, an access network device)", or related illustrations in the drawings can be understood as that the source of the information is the access network device, and it can include directly or indirectly receiving information from the access network device. The information can be processed between the source and the destination of the information sending, for example, format change, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0128] Referring to FIG. 6, FIG. 6 is a flowchart of a communication method provided by an embodiment of the present application. The method can include the following steps:

[0129] S601, the second communication device sends first information on a first resource. Correspondingly, the first communication device receives the first information on the first resource. Wherein, the first information is used to indicate a state of at least one first communication device on a second resource.

[0130] It should be noted that the first communication device in the following embodiments of the present application is any first communication device of the at least one first communication device, that is, each first communication device of the at least one first communication device can implement the function of the following first communication device and perform the action of the following first communication device.

[0131] Wherein, the time interval between the first resource and the third resource is less than or equal to a first threshold, and the third resource is used to carry periodic information.

[0132] In the following embodiments of the present application, the resource is a time and / or frequency resource. For example, the resource is a time resource, and the resource includes one or more time units. The time unit is any one of the following: time domain symbol, time slot, subframe, frame, micro time slot, millisecond (ms), microsecond (μs) or second (s).

[0133] For example, the first resource and the third resource are both time resources. For example, the first resource and the third resource are both one symbol.

[0134] For example, the second resource is a time resource, and the second resource includes T time units, where T is greater than 0. For example, the second resource includes T time slots, or the second resource includes T time units of 20 ms. Wherein, T = 1, or T = 2, or T = 3, or T = 4, or T = 5. Alternatively, the second resource is a frequency resource. For example, the second resource includes N resource blocks, or the second resource includes N bandwidth parts (BWP). Wherein, N is an integer greater than or equal to 1. For example, N = 1, or N = 2. Alternatively, the second resource is a time-frequency resource. For example, the second resource includes T time units and N resource blocks.

[0135] Based on the scheme, the UE can know the behavior on the second resource in advance, thereby determining the behavior on a period of resources in advance, making preparations in advance, and reducing the implementation complexity of the UE.

[0136] For example, the time interval between the first resource and the third resource can be understood as the time domain position interval between the first time domain symbol (the starting time domain symbol) in the time domain symbol included in the first resource and the last time domain symbol (the ending time domain symbol) in the time domain symbol included in the third resource. Alternatively, the time interval between the first resource and the third resource can also be understood as the time domain position interval between the ending time domain symbol in the time domain symbol included in the first resource and the starting time domain symbol in the time domain symbol included in the third resource. Alternatively, the time interval between the first resource and the third resource can also be understood as the interval duration between the starting time of the first resource and the ending time of the third resource. Alternatively, the time interval between the first resource and the third resource can also be understood as the interval duration between the ending time of the first resource and the starting time of the third resource.

[0137] Optionally, the first threshold is predefined. Alternatively, the first threshold is indicated by the second communication device. The predefinition can be understood as predefined by the protocol, or can also be understood as agreed by the second communication device and the first communication device in advance. The manner in which the second communication device determines the first threshold is described in subsequent embodiments, which will not be described here.

[0138] For example, the first threshold is k time units, where k is an integer greater than or equal to 0. For example, k is one of the following: 0, 1, 2, 3, 5, 7, 9, 12, or 14.

[0139] Based on the scheme, in a case that the time interval of the first resource and the third resource is less than the first threshold, the first information can be sent in close proximity to or synchronously with the periodic information, i.e., the second communication device can complete the sending of the first information and the periodic information in a case of entering the active state / wakeup state once, without the need to enter the active state / wakeup state multiple times to send the periodic information and the first information respectively, thereby reducing the number and duration of the activation / wakeup of the second communication device, and reducing the power consumption of the second communication device. Alternatively, based on the scheme, the waiting time between sending the first information and sending the periodic information can be reduced, thereby reducing the overall power consumption of the second communication device.

[0140] Optionally, the periodic information is a common reference signal periodically sent by the second communication device. Alternatively, the periodic information can also be common configuration information periodically sent by the second communication device; or the periodic information can also be common control information periodically sent by the second communication device.

[0141] Illustratively, the periodic information can be any one or more of the following: PSS, SSS, SSB, MIB, SIB, channel status information reference signal (CSI-RS), or tracking reference signal (TRS), etc.

[0142] Based on the scheme, the first information is sent in close proximity to or synchronously with the common information periodically sent by the second communication device, thereby improving the probability of the first communication device receiving the first information, and thereby reducing the power consumption caused by the first communication device entering the wakeup state or performing invalid PDCCH detection without entering the wakeup state or detecting PDCCH due to not receiving the control information (the first information or the WUS). And the waiting time between sending the first information and sending the periodic information by the second communication device can be reduced, thereby reducing the overall power consumption of the second communication device.

[0143] In a possible implementation, the time interval between the first resource and the second resource is less than or equal to a second threshold.

[0144] In a possible implementation, the time domain position of the second resource is after the time domain position of the third resource.

[0145] The time domain position of the second resource being after the time domain position of the third resource can be understood as the position of the first time domain symbol of the second resource being after the last time domain symbol of the third resource, or can also be understood as the start time of the second resource being later than the end time of the third resource.

[0146] Based on the above embodiments, it can be ensured that the first communication device can determine the state of the first communication device on the second resource after detecting the third resource, so as to avoid that the first communication device misses the initial detection time on the second resource due to the time of detecting the periodic information or the first information being later than the start time of the second resource, and the first information indicating that the first communication device performs PDCCH blind detection on the second resource. In this way, it can be ensured that the first communication device will not miss detection on the second resource.

[0147] The time interval between the first resource and the second resource can refer to the description of the time interval between the first resource and the third resource in the foregoing embodiments, and will not be described herein.

[0148] For example, the second threshold is R time units. R is an integer greater than or equal to 0, such as 0, 1, 2, 3, 4, 5, or 6.

[0149] Optionally, the second threshold is predefined. Alternatively, the second threshold is indicated by the second communication device. The predefinition can be understood as an agreement between the first communication device and the second communication device in advance, or can also be understood as a protocol predefined in advance.

[0150] Based on this scheme, it can be avoided that the first communication device has a large reaction delay when the first information indicates that the first communication device enters the wake-up state or detects the PDCCH on the second resource due to the time interval between the first resource and the second resource being too large.

[0151] For example, the state of the first communication device on the second resource is understood as the working state of the first communication device on the second resource. Alternatively, the state of the first communication device on the second resource is understood as the sleep state of the first communication device on the second resource. Alternatively, the state of the first communication device on the second resource is understood as the information receiving state of the first communication device on the second resource. Alternatively, the state of the first communication device on the second resource is understood as the control channel detection state of the first communication device on the second resource. Alternatively, the information receiving state of the first communication device on the second resource is understood as the communication function execution state of the first communication device on the second resource, and so on.

[0152] For example, the state of the first communication device on the second resource can include one or more of the following: whether or not to detect a PDCCH, whether or not to detect a paging, whether or not to be in a wake-up state, or whether or not to be in a sleep state. Whether or not to detect a PDCCH can be understood as whether or not the first communication device performs PDCCH blind detection on all or part of the second resource. Whether or not to detect a paging can be understood as whether or not the first communication device initiates signaling on all or part of the second resource according to a paging message of another communication device, thereby establishing a connection with the sending end of the paging message. Alternatively, whether or not to detect a paging can be understood as whether or not the first communication device detects a PDCCH for indicating a paging message on all or part of the second resource. Whether or not to be in a wake-up state can be understood as whether or not the first communication device is in a high-power consumption state or whether or not to perform a specified communication function (such as wireless signal detection) on the second resource. Whether or not to be in a sleep state can be understood as whether or not the first communication device is in a low-power consumption state or whether or not to perform a specified communication function (such as detection of a paging message) on the second resource.

[0153] For example, the first information can indicate that the state of the at least one first communication device on the second resource is a first state or a second state. In a case where the first information indicates that the state of the at least one first communication device on the second resource is the first state, the second resource carries control information of the at least one first communication device. Or, in a case where the first information indicates that the state of the at least one first communication device on the second resource is the first state, the at least one first communication device is in a wake-up state on the second resource. Or, in a case where the first information indicates that the state of the at least one first communication device on the second resource is the first state, the at least one first communication device receives control information on the second resource.

[0154] In a case where the first information indicates that the state of the at least one first communication device on the second resource is the second state, the second resource does not carry control information of the at least one first communication device. Or, in a case where the first information indicates that the state of the at least one first communication device on the second resource is the second state, the at least one first communication device is in a sleep state on the second resource. Or, in a case where the first information indicates that the state of the at least one first communication device on the second resource is the second state, the at least one first communication device does not receive control information on the second resource. The control information includes at least one of the following: downlink control information, paging information, or sensing information.

[0155] For example, the sensing information can be understood as information for the access network device or the terminal to sense a channel state. Alternatively, the sensing information can be understood as information for the access network device or the terminal to sense one or more terminal positions, etc.

[0156] The first information can be downlink control information. Specifically, the first information is all fields in a DCI, or the first information is part of the fields in a DCI.

[0157] For example, the first information is 1 bit, which has two states of 0 and 1. If the bit is 0, the first information indicates that at least one first communication device is in a first state on the second resource. For example, the first state can include detecting PDCCH or detecting paging on the second resource, or being in a wake-up state, etc. If the bit is 1, the first information indicates that at least one first communication device is in a second state on the second resource. For example, the second state can include not detecting PDCCH or not detecting paging on the second resource, or being in a sleep state, etc.

[0158] For another example, the first information is 1 bit, which has two states of 0 and 1. In the case of the bit being 1, the first information can indicate that at least one first communication device is in a second state on the second resource; in the case of the bit being 0, the first information can indicate that at least one first communication device is in a first state on the second resource.

[0159] In addition, the first information can also be another field that can represent two states. For example, the first information is a state identifier. Or, the first information is a WUS. Or, the first information is a low power wake-up signal (LP-WUS). Or, the first information is a permanent equipment identifier (PEI). The embodiments of the present application are not limited.

[0160] Through the above embodiments, by reducing the time interval between the periodic information and the WUS, the base station can concentrate on sending the periodic information and the WUS, thereby reducing the waiting time between the base station sending the periodic information and sending the WUS, and further reducing the overall power consumption of the base station. Similarly, through the above embodiments, the overall power consumption of the base station when sending the periodic signal and the LP-WUS, or sending the periodic signal and the PEI, can be reduced.

[0161] In a case that the first information indicates that the state of the at least one first communication device on the second resource is the first state, the second communication device can send control information of the at least one first communication device on the second resource. For example, the second communication device sends the control information of the at least one first communication device on the second resource by broadcasting or groupcasting. For example, the second communication device sends DCI on the second resource to indicate information of a group of first communication devices (e.g., terminals). In a case that the first information indicates that the state of the at least one first communication device on the second resource is the second state, the second communication device can not send the control information of the at least one first communication device on the second resource, or the second resource does not carry the control information of the at least one first communication device, or the second resource remains in a sleep state and does not send the control information. The control information includes one or more of downlink control information, paging information, or sensing information.

[0162] For example, in a case that the first information indicates that the at least one first communication device performs PDCCH detection on the second resource, the second resource can carry downlink control information (i.e., the downlink control information is carried by the second resource). Or, in a case that the first information indicates that the at least one first communication device detects paging on the second resource, the second resource can carry paging information (i.e., the paging information is carried by the second resource).

[0163] S602, the first communication device determines the state of the first communication device on the second resource according to the first information.

[0164] For example, after receiving the first information, the first communication device determines the state of the first communication device on the second resource according to the first information. In other words, the first communication device determines whether to detect PDCCH on the second resource, whether to detect paging on the second resource, whether to be in a wake-up state on the second resource, whether to be in a sleep state on the second resource, and the like according to the first information.

[0165] As a possible implementation, after the first communication device determines the state on the second resource, the first communication device performs corresponding processing according to the state. For example, in a case that the first information indicates that the state of the first communication device on the second resource is to detect PDCCH, the first communication device detects PDCCH on the second resource. Or, in a case that the first information indicates that the state of the first communication device on the second resource is to detect paging, the first communication device detects paging on the second resource.

[0166] Based on the scheme, the second communication device can send the first information on the first resource to indicate the state of the at least one first communication device on the second resource. Since the time interval between the first resource and the third resource carrying the periodic information is less than the first threshold, the transmission interval between the first information and the periodic information can be very small or even simultaneous. The second communication device does not need to re-enter the wake-up state or the active state to send the first information after sending the periodic information and entering the sleep state, thereby reducing the number of times the second communication device wakes up or activates when sending control information to schedule the first communication device, reducing the total time the second communication device is in the wake-up state or the active state, and reducing the power consumption of the second communication device. In addition, since the transmission of the first information can reduce the power consumption of the second communication device compared to the transmission of the current WUS, the impact on the second communication device is small. Therefore, the probability of the second communication device sending the first information is greater than the probability of the second communication device sending the WUS, and the probability of the first communication device obtaining the first information is greater than the probability of the first communication device obtaining the WUS. This reduces the power consumption caused by the first communication device entering the wake-up state or performing invalid PDCCH detection without entering the wake-up state or detecting the PDCCH due to not receiving the control information (the first information or the WUS). Therefore, the power consumption of the first communication device is reduced.

[0167] The overall flow of the communication method provided by the present application is described above. The specific implementation of each step in the above method is described in detail below.

[0168] In one possible implementation, the time interval between the first resource and the third resource in step S601 corresponds to a first threshold of 0, i.e., the first resource is adjacent to the third resource.

[0169] The first resource adjacent to the third resource can be understood as the time domain symbols included in the first resource partially overlapping the time domain symbols included in the third resource. Alternatively, the first resource adjacent to the third resource can be understood as the time domain symbols included in the third resource containing the time domain symbols included in the first resource (i.e., the time domain position of the first resource is within the time domain position of the third resource). Alternatively, the first resource adjacent to the third resource can be understood as the first time domain symbol of the first resource adjacent to the last time domain symbol of the third resource. The time domain symbols included in the third resource can also be understood as the time domain symbols occupied by the third resource, and the time domain symbols included in the first resource can also be understood as the time domain symbols occupied by the first resource.

[0170] For example, the first resource includes a plurality of sub-resources, the third resource includes a plurality of sub-resources, and the first resource and the third resource are adjacent, which means that the first sub-resource included in the first resource is adjacent to the last sub-resource included in the third resource, or the last sub-resource included in the first resource is adjacent to the first sub-resource included in the third resource, or the first sub-resource included in the first resource is adjacent to any one of the sub-resources included in the third resource. Among them, the last sub-resource refers to the sub-resource that is the latest in time. The first sub-resource refers to the sub-resource that is the earliest in time.

[0171] In a possible implementation, the first communication device detects the periodic information on the third resource.

[0172] As a possible implementation, in the case where the last sub-resource included in the first resource is adjacent to the first sub-resource included in the third resource, after step S601, the first communication device detects the periodic information on the third resource.

[0173] As another possible implementation, in the case where the first sub-resource included in the first resource is adjacent to the last sub-resource included in the third resource, before step S601, the first communication device detects the periodic information on the third resource.

[0174] The first communication device detecting the periodic information on the third resource can be understood as the first communication device detecting the periodic information on all resources included in the third resource. Alternatively, the first communication device detects the periodic information on part of the resources included in the third resource. Alternatively, the first communication device receives the periodic information on all resources included in the third resource. Alternatively, the first communication device receives the periodic information on part of the resources included in the third resource.

[0175] For example, the third resource carries a synchronization signal burst set, and the third resource includes M sub-resources, each of which carries an SSB. The first communication device receives the periodic information on one sub-resource of the third resource, that is, the first communication device receives an SSB on one SSB beam of the plurality of SSB beams included in the synchronization signal burst set.

[0176] In a possible implementation, the third resource includes M sub-third resources, and the M sub-third resources are not adjacent to each other; the first resource corresponds to M sub-first resources, and the M sub-first resources are also not adjacent to each other, and M is an integer greater than or equal to 1.

[0177] For example, the M sub-third resources respectively carry M SSBs, and the M sub-first resources respectively carry M sub-information blocks of the first information. Any one of the M sub-information blocks of the first information is associated with the N first communication devices. The association of any one of the sub-information blocks with the N first communication devices means that the N first communication devices are consistent with the beam of the associated sub-information block, or the N first communication devices can receive the associated sub-information block.

[0178] The first resource is adjacent to the third resource, which means that the first sub-first resource is adjacent to the last sub-third resource. Alternatively, the first resource is adjacent to the third resource, which means that the first sub-third resource is adjacent to the last sub-first resource. Alternatively, the first resource is adjacent to the third resource, which means that each of the M sub-third resources is adjacent to each of the M sub-first resources, i.e., the first time domain symbol of each sub-first resource is adjacent to the last time domain symbol of the corresponding sub-third resource.

[0179] The last sub-resource means the last sub-resource in time. The first sub-resource means the first sub-resource in time.

[0180] For example, the periodic information is SSB, the first resource and the third resource are time domain resources, the time domain symbols included in the third resource include the time domain symbols included in the first resource, and the first information is used to indicate whether at least one first communication device detects PDCCH on the second resource. Referring to (a) in FIG. 7, one synchronization signal burst set of the second communication device includes SSB1, SSB2, SSB3, and SSB4, the transmission period of the synchronization signal burst set is 40 ms, the first information includes four sub-information blocks: first information 1, first information 2, first information 3, and first information 4, and the beam direction of each sub-information block is the same as the beam direction of the SSB with the same serial number. The second communication device respectively transmits SSB1, SSB2, SSB3, and SSB4 to different beam directions through the specified resources within the transmission period of one synchronization signal burst set. The first communication device is in the beam direction of SSB2, i.e., the first communication device receives SSB2. Then the first communication device receives SSB2 on the third resource, and receives the first information 2 in the sub-information block of the first information which is the same as the beam direction of SSB2 on the first resource. That is, the first communication device receives SSB2 on the frequency domain resource corresponding to the time domain symbol included in the third resource, and receives first information 2 on the frequency domain resource corresponding to the time domain symbol included in the first resource.

[0181] In the case that the first time-domain symbol corresponding to the first information 2 is adjacent to the last time-domain symbol corresponding to the SSB 2, the first information 2 is sent immediately before the SSB 2. In the case that the first information 2 sent immediately before the SSB 2 indicates that at least one first communication device detects the PDCCH on the second resource, the first communication device performs PDCCH detection (PDCCH blind detection) on the second resource; in the case that the first information 2 sent immediately before the SSB 2 indicates that no detection is performed on the PDCCH, the first communication device remains dormant (no detection is performed on the PDCCH) on the second resource.

[0182] In the above example, the sub-information block of the first information (the first information 2) is only used to indicate the state of the first communication device in the beam direction of the SSB 2.

[0183] For another example, taking the case that the periodic information is the SSB, the first resource and the third resource are time-domain resources, the time-domain symbol included in the third resource is adjacent to the time-domain symbol included in the first resource, and the first information is used to indicate whether at least one first communication device detects the PDCCH on the second resource as an example. Referring to (b) in FIG. 7, one synchronization signal burst set of the second communication device includes: SSB 1, SSB 2, SSB 3 and SSB 4, the transmission period of the synchronization signal burst set is 40 ms, and the second communication device respectively sends SSB 1, SSB 2, SSB 3 and SSB 4 to different beam directions through the specified resource in the transmission period of one synchronization signal burst set. The first communication device is in the beam direction of the SSB 2, that is, the first communication device receives the SSB 2. Then the first communication device receives the SSB 2 on the third resource and receives the first information on the first resource.

[0184] In the case that the first time-domain symbol corresponding to the first information 2 is adjacent to the last time-domain symbol corresponding to the SSB 2, the first information 2 is sent immediately before the SSB 2. In the case that the first information 2 sent immediately before the SSB 2 indicates that at least one first communication device detects the PDCCH on the second resource, the first communication device performs PDCCH detection (PDCCH blind detection) on the second resource; in the case that the first information 2 sent immediately before the SSB 2 indicates that no detection is performed on the PDCCH, the first communication device remains dormant (no detection is performed on the PDCCH) on the second resource.

[0185] In the above example, the first information is used to indicate the status of the first communication device in an arbitrary beam direction. That is, the first information indicates the status of the first communication device in the plurality of beam directions on the second resource. Alternatively, the first information can indicate the status of all the first communication devices on each beam in the SSB burst set on the second resource. In this case, the first information can be transmitted to the first communication device in each beam direction on a plurality of different resource blocks in the first resource. Alternatively, the first information can be transmitted to the first communication device on each SSB beam on a plurality of resource blocks in the first resource.

[0186] For another example, taking the periodic information as the SSB, the first resource and the third resource are time domain resources, the time domain symbols included in the third resource are adjacent to the time domain symbols included in the first resource, and the first information is used to indicate whether the at least one first communication device detects the PDCCH on the second resource. Referring to (c) in FIG. 7, one synchronization signal burst set of the second communication device includes SSB1, SSB2, SSB3 and SSB4, the transmission period of the synchronization signal burst set is 40 ms, the first information includes four sub-information blocks: first information 1, first information 2, first information 3 and first information 4, and the beam direction of each sub-information block is the same as the beam direction of the SSB with the same serial number. The second communication device respectively transmits SSB1, SSB2, SSB3 and SSB4 to different beam directions through the specified resource in the transmission period of one synchronization signal burst set. The first communication device is in the beam direction of SSB2, that is, the first communication device receives SSB2. Then the first communication device receives SSB2 on the third resource and receives the first information 2 in the sub-information block of the first information on the first resource, which is in the beam direction of SSB2.

[0187] In the case where the first time domain symbol corresponding to the first resource is adjacent to the last time domain symbol corresponding to the third resource, the plurality of sub-information blocks of the first information are transmitted immediately next to each other on the first resource. In the case where the first information 2 indicates that the at least one first communication device detects the PDCCH on the second resource, the first communication device performs PDCCH detection (PDCCH blind detection) on the second resource; in the case where the first information 2 indicates that no detection is performed on the PDCCH, the first communication device remains dormant (no detection on the PDCCH) on the second resource.

[0188] In the above example, the first information is used to indicate the status of the first communication device in the beam direction of SSB2.

[0189] In the above embodiments, the time domain interval of the first information and the periodic information is 0, and the first information can be sent in time or synchronously with the periodic information, that is, the second communication device can complete the sending of the first information and the periodic information in the case of entering the wake-up state once, without entering the wake-up state multiple times to send the periodic information and the first information respectively, thereby reducing the number of wake-up times and the duration of the wake-up state in the process of sending the control information by the second communication device. At the same time, in the case that the first communication device has no scheduling between the two periodic information sending time points, the second communication device can enter the sleep state after sending the periodic information and the first information, until the next periodic information is sent to the first communication device, thereby effectively shortening the duration of the high-power state (wake-up state) of the second communication device and reducing the power consumption of the second communication device. In addition, the sending of the first information can reduce the power consumption of the second communication device compared to the sending of the current WUS, and has less impact on the second communication device. The probability of the second communication device sending the first information is greater than the probability of the second communication device sending the WUS, and the probability of the first communication device obtaining the first information is greater than the probability of the first communication device obtaining the WUS. The power consumption caused by the first communication device entering the wake-up state or performing invalid PDCCH detection without entering the wake-up state or detecting the PDCCH due to not receiving the control information (the first information or the WUS) is reduced, thereby reducing the power consumption of the first communication device.

[0190] In addition, in the case that the time domain symbol included in the third resource contains the time domain symbol included in the first resource, that is, the first information and the periodic information are sent synchronously in time, the first information can be carried by the bearing information, the first information can be represented by a specified field in the bearing information, or the first information can directly act as a specified bearing information. The bearing information can include at least one of the following: a downlink signal, downlink data, downlink configuration information, downlink control information, a sensing signal, a duplex signal, or a backhaul signal.

[0191] Exemplarily, the downlink signal can be a demodulation reference signal (DMRS) in a downlink reference signal (DLRS), a CSI-RS, or a positioning reference signal. The DMRS refers to a DMRS of a downlink channel, for example, a DMRS of a PDCCH or a DMRS of a physical downlink shared channel (PDSCH), and the like. The downlink control information can be DCI, and the downlink configuration information can be radio resource control (RRC) information or medium access control-control element (MAC-CE) information, and the like.

[0192] In a possible implementation, the first information sent by the second communication device on the first resource in step S601 is used to indicate the states of the N first communication devices on the second resource. That is, the first information received by the first communication device on the first resource is used to indicate the states of the N first communication devices on the second resource. Wherein, N is an integer greater than 1. At this time, the N first communication devices refer to N different first communication devices.

[0193] Exemplarily, the N first communication devices can satisfy one or more of the following: the N first communication devices are associated with the same beam, the N first communication devices are associated with the same second resource, the N first communication devices are associated with the same SSB index, and the N first communication devices are associated with the same group number.

[0194] The beam associated with the N first communication devices can be understood as that the N first communication devices can receive the first information in the same beam direction. For example, the transmission of the first information can refer to the description of the SSB scanning in the foregoing embodiments. The access network device can implement the cell coverage of the SSB by transmitting different SSBs on different beams, and the second communication device can also transmit the first information in a manner similar to the transmission of the SSB by the access network device. That is, the first information can be carried by a narrowband beam, and the states of the N first communication devices on the second resource in the coverage range of the narrowband beam can be controlled.

[0195] The second resources associated with the N first communication devices being the same can be understood as the time lengths and / or time domain positions of the second resources corresponding to the N first communication devices being the same. The second communication device can determine the time lengths and time domain positions of the second resources corresponding to each first communication device in advance, and then group the first communication devices according to the time lengths and time domain positions of the corresponding second resources, and the first communication devices in the same group are associated with the same second resources (i.e., the time lengths and time domain positions of the corresponding second resources are the same). That is, the first information indicates the states of the N first communication devices corresponding to the same second resources on the second resources.

[0196] The SSB indexes associated with the N first communication devices being the same can be understood as the N first communication devices being able to receive the same SSB. The first information can be carried by the first beam, and the parameters of the first beam are the same as the parameters of the SSB beam, or the first information can be directly carried by the SSB beam. Therefore, the N first communication devices that are able to receive the first information belong to the first communication devices in the beam direction that transmit the same SSB, i.e., the N first communication devices associated with the same SSB index. That is, the first information can indicate the states of the N first communication devices that are able to receive the same SSB on the second resources.

[0197] The group numbers associated with the N first communication devices being the same can be understood as the N first communication devices corresponding to the same group number, or the N first communication devices belonging to the same group. Before the second communication device distributes the first information, the second communication device can divide the first communication devices into multiple groups according to the position information (such as coordinates, positioning data, etc.) of the first communication devices, and determine the group numbers corresponding to each first communication device, wherein the first communication devices corresponding to the same group number are able to receive the same broadcast message, or the first communication devices corresponding to the same group number are in the coverage range of the same broadcast message. When the second communication device sends the first information through a specific broadcast message, the second communication device can indicate the states of the N first communication devices in the coverage range of the broadcast message on the second resources, i.e., the first information indicates the states of the N first communication devices associated with the same group number on the second resources.

[0198] Through the schemes in the above embodiments, one first information is used to indicate the states of the N first communication devices on the second resources, which significantly reduces the signaling overhead of the second communication device when controlling the states of the multiple first communication devices on the second resources, and is beneficial to reducing the power consumption of the second communication device in the process of sending the first information.

[0199] Optionally, the first information indicating the states of the N first communication devices on the second resources can be implemented in the following two ways:

[0200] In the first mode, the first information includes at least one bit, and the bit is used to indicate the state of the N first communication devices on the second resource.

[0201] For example, the first information is one bit, and the bit has two states of 0 and 1. In the case of 0, the first information can indicate that the N first communication devices detect PDCCH, or detect paging, or enter a wake-up state, etc. on the second resource. In the case of 1, the first information can indicate that the N first communication devices remain in a sleep state, or do not detect PDCCH, or do not detect paging, etc. on the second resource. In the case that the first information includes one bit used to indicate the state of the N first communication devices on the second resource, the resource occupation of the first information is small, and the power consumption of the second communication device caused by sending the first information is also low, which is beneficial to further control the power consumption of the second communication device in the process of sending the first information.

[0202] In the second mode, the first information includes at least N bits, and each of the N bits is used to indicate the state of one of the N first communication devices on the second resource.

[0203] For example, the first information is a bitmap including N bits, and each bit in the bitmap has two states of 0 and 1, and each bit is used to indicate the state (such as whether to detect PDCCH) of one of the N first communication devices corresponding to the bit on the second resource. For example, in the case that there is scheduling for the target first communication device on the second resource, the bit corresponding to the target first communication device is set to 0, indicating that the target first communication device detects PDCCH, or detects paging, etc. on the second resource. In the case that there is no scheduling for the target first communication device on the second resource, the bit corresponding to the target first communication device is set to 1, indicating that the target first communication device remains in a sleep state on the second resource, wherein the target first communication device is any one of the N first communication devices.

[0204] Optionally, each bit in the bitmap can be set to the same state (such as each bit is set to 0 or 1), or can be set to different states (such as part of the bits are set to 0, and the remaining bits are set to 1).

[0205] In the case that the first information includes N bits, the second communication device can accurately control the state of each of the N first communication devices on the second resource by setting the state of each bit, thereby greatly improving the control flexibility of the first communication devices, and reducing the number of wake-ups and power consumption of the first communication devices without scheduling as much as possible.

[0206] In a possible implementation, the at least one first communication device includes a plurality of first communication devices, each of the plurality of first communication devices corresponds to a second resource. Optionally, the second resources corresponding to different first communication devices in the plurality of first communication devices can be the same or different. The first information sent by the second communication device on the first resource in step S601 is used to indicate not only the state of the first communication device on the second resource, but also the second resource corresponding to the first communication device. That is, the first information sent by the second communication device on the first resource is used to indicate, for each of the at least one first communication device, the second resource corresponding to the first communication device and the state of the first communication device on the second resource. In other words, the first information received by the first communication device on the first resource is used to indicate the second resource corresponding to the first communication device and the state of the first communication device on the second resource.

[0207] For example, the first information includes first sub-information and second sub-information, the first sub-information is used to indicate the second resource corresponding to the first communication device, and the second sub-information is used to indicate the state of the first communication device on the second resource. For example, the first sub-information can include the device identifier of the first communication device and the identifier of the second resource; or the first sub-information includes the device identifier of the first communication device or the second resource.

[0208] In the case where the first information indicates the states of the plurality of first communication devices on the second resource, the first information can include a plurality of information blocks, each of the information blocks includes the first sub-information and the second sub-information. Each of the information blocks is used to indicate, for one of the at least one first communication device, the second resource corresponding to the first communication device and the state of the first communication device on the second resource.

[0209] That is, the second resources corresponding to different first communication devices in the plurality of first communication devices can be the same or different.

[0210] For example, the first information includes information block 1, information block 2 and information block 3, the information block 1 indicates that the second resource corresponding to the first communication device 1 is L1, and the state of the first communication device 1 on L1 is to detect PDCCH; the information block 2 indicates that the first resource corresponding to the first communication device 2 is L2, and the state of the first communication device 2 on L2 is to detect PDCCH; and the information block 3 indicates that the first resource corresponding to the first communication device 3 is L1, and the state of the first communication device 3 on L1 is to keep dormant (not to detect PDCCH). By indicating the second resource corresponding to the first communication device and the state of the first communication device on the second resource through the first information, the control of each first communication device is more flexible and accurate, the wake-up time and the wake-up times of the first communication device are reduced as much as possible, and the energy consumption of the first communication device is further reduced.

[0211] In a possible implementation, before step S601, the first communication device can further send second information. Correspondingly, the second communication device can further receive the second information from the first communication device. The second information is used to indicate the time interval between the first resource and the third resource supported by the first communication device. The second communication device can determine the first threshold value according to the second information.

[0212] For example, the second information used to indicate the time interval between the first resource and the third resource supported by the first communication device can be understood as the second information used to indicate the maximum value and / or the minimum value of the time interval between the first resource and the third resource supported by the first communication device. For example, the second information can be at least one of the following: the target power consumption of the first communication device, the maximum value of the first threshold value or the minimum value of the first threshold value, wherein the maximum value of the first threshold value and the minimum value of the first threshold value can be calculated by the first communication device according to the target power consumption, which will not be described here.

[0213] The second communication device can determine the first threshold value according to the second information through the following two steps:

[0214] Step one, the second communication device determines the first interval according to the second information from the first communication device.

[0215] For example, the first interval is used to indicate the range of the time interval between the first resource and the third resource. After obtaining the second information, the second communication device determines the time interval between the first resource and the third resource that can be supported by the first communication device according to the analysis result of the second information, obtains the maximum value (t1) and / or the minimum value (t2) of the time interval between the first resource and the third resource that can be supported by the first communication device, and then determines t1 as the upper limit of the interval of the first interval and / or determines t2 as the lower limit of the interval, to determine the first interval.

[0216] The second communication device determines the first interval according to the second information in the following four ways:

[0217] Way 1, taking the maximum of the first threshold value as an example. After the second communication device analyzes the maximum of the first threshold value, the second communication device takes the maximum of the first threshold value as the upper limit of the interval of the first interval, and directly takes the open interval less than or equal to the maximum of the first threshold value as the first interval.

[0218] Alternatively, the second communication device can also determine the maximum transmission interval between the periodic information and the first information according to the maximum duration of single wake-up of the second communication device. In the case where the maximum transmission interval is less than the maximum of the first threshold value, the maximum transmission interval is directly taken as the lower limit of the interval of the first interval; in the case where the maximum transmission interval is greater than the maximum of the first threshold value, a transmission interval less than the maximum of the first threshold value is selected as the lower limit of the interval of the first interval, and the first interval is determined.

[0219] Way 2, taking the minimum of the first threshold value as an example. The second communication device takes the minimum of the first threshold value as the lower limit of the interval of the first interval, and directly takes the open interval greater than or equal to the minimum of the first threshold value as the first interval.

[0220] Alternatively, the second communication device can also determine the maximum transmission interval between the periodic information and the first information according to the maximum duration of single wake-up of the second communication device, and select a value less than or equal to the maximum transmission interval as the upper limit of the interval of the first interval to determine the first interval.

[0221] Way 3, taking the target power consumption of the first communication device as an example. The second communication device can directly determine the maximum transmission interval and the minimum transmission interval between the first information and the periodic information that can be supported by the first communication device according to the target power consumption of the first communication device, take the minimum transmission interval as the lower limit of the interval of the first interval, and take the maximum transmission interval as the upper limit of the interval of the first interval to determine the first interval.

[0222] Way 4, taking the maximum (t1) and the minimum (t2) of the first threshold value as an example. The second communication device can directly take t1 as the upper limit of the interval of the first interval, and take t2 as the lower limit of the interval of the first interval to determine the first interval.

[0223] Step 2, the second communication device determines the first threshold value according to the first interval.

[0224] Exemplarily, after determining the first interval, the second communication device can randomly select an integer value in the first interval as the first threshold. Alternatively, the second communication device can determine the lower limit or the upper limit of the first interval as the first threshold according to a preset rule, etc. In this way, the second communication device can determine the first threshold according to the second information, and then synchronously or successively transmit the periodic common information and the first information in a short interval, so as to reduce the power consumption of the first communication device and the second communication device caused by the transmission and reception of the first information, thereby reducing the power consumption of the first communication device and the second communication device, or making the power consumption of the first communication device less than or equal to the target power consumption.

[0225] In a possible implementation, before step S601, the first communication device can further transmit third information. Correspondingly, the second communication device can further receive the third information from the first communication device. The third information is used to indicate the time interval between the first resource and the second resource supported by the first communication device. The second communication device can determine the second threshold according to the third information.

[0226] Exemplarily, the third information can be at least one of the maximum value of the second threshold, the minimum value of the second threshold, or the second threshold. The second communication device can determine the second threshold according to the third information in the following four ways:

[0227] In the first way, the third information is the second threshold, and the second communication device directly determines the third information as the second threshold.

[0228] In the second way, the third information is the minimum value of the second threshold, and the second communication device can determine any value greater than or equal to the minimum value of the second threshold as the second threshold.

[0229] In the third way, the third information is the maximum value of the second threshold, and the second communication device can determine any value less than or equal to the maximum value of the second threshold as the second threshold.

[0230] In the fourth way, the third information is the minimum value of the second threshold and the maximum value of the second threshold, and the second communication device can determine the minimum value of the second threshold and the maximum value of the second threshold as the upper limit and the lower limit of the second interval respectively, and determine any element in the second interval as the second threshold.

[0231] Exemplarily, the third information can be determined according to the wake-up delay of the first communication device. The wake-up delay of the first communication device can be understood as the time length required for the first communication device to enter the wake-up state from the sleep state, or the time length required for the first communication device to start a specific communication function (such as PDCCH detection or paging detection, etc.).

[0232] For example, the wake-up delay of the first communication device is 3 time domain symbols, the third information can indicate that the minimum value of the second threshold is 3 time domain symbols; or the third information can indicate that the second threshold is 5 time domain symbols, and so on.

[0233] In a possible implementation, before step S601, the first communication device can further send fourth information. Correspondingly, the second communication device receives the fourth information from the first communication device. The fourth information is used to indicate at least one of the following supported by the first communication device: the time length of the second resource, the minimum time length of the second resource, or the maximum time length of the second resource. The second communication device is further configured to determine the time length of the second resource according to the fourth information.

[0234] For example, the second communication device can determine the time length of the second resource in the following four ways:

[0235] In the first way, when the fourth information indicates the time length of the second resource, the second communication device directly determines the time length of the second resource as the time length of the second resource indicated by the fourth information.

[0236] In the second way, when the fourth information indicates the minimum time length of the second resource, the second communication device can determine the first time length as the time length of the second resource, where the first time length is greater than or equal to the minimum time length.

[0237] In the third way, when the fourth information indicates the maximum time length of the second resource, the second communication device determines the second time length as the time length of the second resource, where the first time length is less than or equal to the maximum time length.

[0238] In the fourth way, when the fourth information indicates the minimum time length of the second resource and the maximum time length of the second resource, the second communication device can randomly select a value in a second interval as the time length of the second resource, where the upper limit of the second interval is the maximum time length of the second resource, and the lower limit of the second interval is the minimum time length of the second resource.

[0239] For example, the fourth information can be determined according to the target power consumption and / or target transmission delay of the first communication device. The target power consumption can be understood as the power consumption of the first communication device per unit time, and the target transmission delay can be understood as the time length required by the first communication device to implement a specific communication function, such as the time length required to complete PDCCH detection or paging detection.

[0240] For example, the first communication device can determine, according to the target power consumption, a minimum sleep duration for the first communication device to be in the sleep state on the second resource when the first information indicates the minimum sleep duration, and determine the minimum time length of the second resource as the target detection duration for the first communication device to complete one PDCCH detection according to the target transmission delay.

[0241] It is worth mentioning that, in the process of sending the second information, the third information and the fourth information, the first communication device can carry two or all of the second information, the third information or the fourth information through different fields of the same message respectively; or the first communication device can send the second information, the third information or the fourth information through different messages respectively, and the embodiments of the present application are not limited.

[0242] In a possible implementation, before step S601, the second communication device can further send fifth information. Correspondingly, the first communication device can further receive the fifth information. The fifth information is used to indicate the first search space and the second search space. If the first information indicates that the first communication device detects the PDCCH on the second resource, the first communication device detects the PDCCH according to the first search space when the first condition is met, and detects the PDCCH according to the second search space when the second condition is met.

[0243] The first search space and the second search space satisfy one or more of the following: the period of the first search space is greater than the period of the second search space, the duration of the first search space is less than the duration of the second search space, the pattern density corresponding to the first search space is greater than the pattern density corresponding to the second search space, the aggregation level of the first search space is less than the aggregation level of the second search space, or the frequency domain range corresponding to the first search space is less than the frequency domain range corresponding to the second search space.

[0244] For example, the second search space can be a common search space (CSS) and / or a UE-specific search space (USS).

[0245] In a case that the period of the first search space is greater than the period of the second search space or the duration of the first search space is less than the duration of the second search space, the interval of detecting the PDCCH according to the first search space is greater than the interval of detecting the PDCCH according to the second search space; in a case that the pattern density corresponding to the first search space is greater than the pattern density corresponding to the second search space, the aggregation level of the first search space is less than the aggregation level of the second search space, or the frequency domain range corresponding to the first search space is less than the frequency domain range corresponding to the second search space, the blind detection range when detecting the PDCCH according to the first search space is lower than the blind detection range when detecting the PDCCH according to the second search space. Therefore, when detecting the PDCCH according to the first search space, compared with detecting the PDCCH according to the second search space, it is equivalent to extending the blind detection interval of the PDCCH and / or reducing the blind detection range of the PDCCH, thereby reducing the power consumption of the first communication device when detecting the PDCCH.

[0246] Optionally, the first condition can include one or more of the following: the first communication device is in an energy saving state, the first communication device detects the downlink control channel in the first time window, or the first communication device detects the downlink control channel in the second resource.

[0247] For example, the first communication device being in an energy saving state can be understood as the target power consumption of the first communication device being lower than a first threshold or the power consumption level of the first communication device being lower than a first level. The first communication device detecting the downlink control channel in the first time window can be understood as the first information indicating that, when the first communication device detects the PDCCH on the second resource, the time domain symbol of the first time window contains the time domain symbol of the second resource, and / or the frequency range included in the first time window contains the frequency range included in the second resource. The first communication device detecting the downlink control channel in the second resource can be understood as the first information indicating that the first communication device detects the PDCCH on the second resource.

[0248] The first time window can be understood as a time-frequency resource, and the first time window can be predefined. Alternatively, the first time window can be indicated by the second communication device. Predefined can be understood as being agreed by the first communication device and the second communication device in advance, or can also be understood as being predefined by a protocol.

[0249] The position of the first time window can be determined according to one or more of the following: the frame in which the first time window is located, the subframe in which the first time window is located, the time slot in which the first time window is located, the time domain symbol included in the first time window, or the time interval between the first time window and the first resource. The time interval between the first time window and the first resource can be understood as the time domain position interval between the first time domain symbol included in the first time window and the last time domain symbol included in the first resource.

[0250] Optionally, the second condition can include one or more of the following: the first communication device is not in the power saving state, the first communication device detects the downlink control channel outside the first time window, or the first communication device detects the downlink control channel outside the second resource. The meaning of the second condition can refer to the description of the meaning of the first condition above, with the difference that the second condition is the opposite of the first condition, which will not be repeated here.

[0251] For example, in the case where the search space includes a first search space and a second search space, the first information indicating that the plurality of first communication devices detect the PDCCH can include the following two implementations:

[0252] Method one: the first information indicates that the plurality of first communication devices detect the PDCCH according to the satisfied condition. For example, the first communication device 1 and the first communication device 3 satisfy the first condition, and the first communication device 2 satisfies the second condition. The first information indicates that the first communication device 1, the first communication device 2 and the first communication device 3 detect the PDCCH on the second resource, the first communication device 1 and the first communication device 3 detect the PDCCH according to the first search space, and the first communication device 2 detects the PDCCH according to the second search space.

[0253] Method two: the first information indicates that the first communication device satisfying the first condition detects the PDCCH. For example, the first communication device 1 and the first communication device 3 satisfy the first condition, and the first communication device 2 satisfies the second condition. The first information can indicate that the first communication device 1 and the first communication device 3 detect the PDCCH on the second resource according to the first search space, and indicate that the second communication device 2 remains dormant (does not detect the PDCCH) on the second resource.

[0254] Optionally, the fifth information can be carried by different fields of the same message as the first information; or the fifth information is carried by other messages, for example, RRC information, MAC-CE information or DCI, etc.

[0255] Based on the above scheme, the time interval of the first resource occupied by the first information and the third resource occupied by the periodic information sent by the second communication device is less than the first threshold value, so that the transmission interval between the first information and the periodic information is extremely short or even synchronous transmission can be realized. In the case of entering an active state or a wake-up state, the second communication device can complete the transmission of the first information and the periodic information, without the need to enter the active state or the wake-up state multiple times to transmit the first information and the periodic information respectively, thereby reducing the number of wake-up times and the length of time in the process of transmitting control information by the second communication device, and further reducing the power consumption of the second communication device. In addition, since the transmission of the first information can reduce the power consumption of the second communication device compared to the transmission of the current WUS, the impact on the second communication device is small, therefore, the probability of the second communication device transmitting the first information is greater than the probability of the second communication device transmitting the WUS, and the probability of the first communication device obtaining the first information is greater than the probability of the first communication device obtaining the WUS, thereby reducing the power consumption caused by the first communication device entering the wake-up state or performing invalid PDCCH detection without entering the wake-up state or detecting the PDCCH due to not receiving the control information (the first information or the WUS), thereby reducing the power consumption of the first communication device and effectively balancing the power consumption of the first communication device and the second communication device.

[0256] Referring to FIG. 8, FIG. 8 is a flowchart of another communication method provided by an embodiment of the present application, which can include the following steps:

[0257] S801, the second communication device transmits fifth information. Correspondingly, the first communication device receives the fifth information. The fifth information indicates a first search space and a second search space.

[0258] For example, the first search space and the second search space satisfy one or more of the following: the period of the first search space is greater than the period of the second search space, the duration of the first search space is less than the duration of the second search space, the pattern density corresponding to the first search space is greater than the pattern density corresponding to the second search space, the aggregation level of the first search space is less than the aggregation level of the second search space, or the frequency domain range corresponding to the first search space is less than the frequency domain range corresponding to the second search space.

[0259] For example, the second search space can be a common search space CSS and / or a UE-specific search space USS.

[0260] For example, the fifth information includes the first search space and the second search space. Alternatively, the fifth information includes the second search space and the relationship between the aggregation levels of the first search space and the second search space. Alternatively, the fifth information includes the second search space and the relationship between the frequency domain ranges of the first search space and the second search space, etc.

[0261] S802, the first communication apparatus determines the search space for detecting the downlink control channel according to the fifth information.

[0262] For example, after receiving the fifth information, the first communication apparatus can determine the first search space and the second search space according to the fifth information. Before detecting the PDCCH, the first communication apparatus can determine the search space for detecting the PDCCH according to the current state and / or the time for detecting the PDCCH.

[0263] Based on the above scheme, the first search space and the second search space are defined in advance, and the first communication apparatus can select different search spaces to detect the PDCCH. In the case of detecting the PDCCH using the first search space, the detection interval of the PDCCH can be effectively increased, and / or the blind detection range when detecting the PDCCH can be effectively reduced, thereby significantly reducing the power consumption of the first communication apparatus when detecting the PDCCH.

[0264] In a possible implementation, the first communication apparatus can detect the PDCCH according to the first search space when a first condition is met, and detect the PDCCH according to the second search space when a second condition is met. That is, in the process of detecting the PDCCH, when the first condition is met, the search space of the downlink control channel is the first search space; and when the second condition is met, the search space of the downlink control channel is the second search space.

[0265] For example, the first condition can include one or more of the following: the first communication apparatus is in an energy saving state, the first communication apparatus detects the downlink control channel within a first time window, or the first communication apparatus detects the downlink control channel within a first resource.

[0266] The first communication apparatus being in an energy saving state can be understood as the target power consumption of the first communication apparatus being lower than a first threshold, or the power consumption level of the first communication apparatus being lower than a first level. The first communication apparatus detecting the downlink control channel within a first time window can be understood as the time domain symbols of the first time window containing the time domain symbols of the resource occupied by the first communication apparatus when detecting the PDCCH, and / or the frequency range included by the first time window containing the frequency range of the resource occupied by the first communication apparatus when detecting the PDCCH, etc. The first communication apparatus detecting the downlink control channel within a first resource can be understood as the first communication apparatus detecting the PDCCH on a specified first resource, such as on a specified time domain symbol or within a specified frequency range.

[0267] The first time window can be understood as a time-frequency resource, and the first time window can be predefined. Alternatively, the first time window can be indicated by the second communication apparatus. Predefined can be understood as being agreed upon in advance by the first communication apparatus and the second communication apparatus, or can also be understood as being predefined by a protocol.

[0268] Referring to FIG. 9, taking the first communication device detecting the downlink control channel in the first time window in the first condition as an example. After the fifth information is received and the first search space and the second search space are determined, when the first communication device is instructed by the second communication device to detect the PDCCH on the first resource, before detecting the PDCCH, the first communication device can detect whether the first condition is met, that is, whether the time domain symbols of the first resource are all in the time domain symbol set corresponding to the first time window (that is, the set composed of the time domain symbols of the first time window); or whether the time domain symbols of the first resource can all be found in the time domain symbols of the first time window. If the first condition is met, the first communication device detects the PDCCH on the first resource according to the first search space according to the instruction of the second communication device; if the first condition is not met, the first communication device detects the PDCCH on the first resource according to the second search space according to the instruction of the second communication device.

[0269] For example, the second condition includes one or more of the following: the first communication device is not in the energy saving state, the first communication device detects the downlink control channel outside the first time window, or the first communication device detects the downlink control channel outside the first resource. The meaning of the second condition can refer to the description of the meaning of the first condition described above, and the difference is that the second condition is the opposite condition of the first condition, which will not be described here.

[0270] In a possible implementation, the fifth information can be carried by a specific field in the periodic information, or the fifth information can be served by a designated periodic information. For example, the fifth information can be carried by at least one of the following: a downlink signal, downlink data, downlink configuration information, downlink control information, a sensing signal, a duplex signal, or a backhaul signal, etc.

[0271] For example, the downlink signal can be a DMRS, a CSI-RS, or a positioning reference signal in the downlink reference signal. The DMRS refers to the DMRS of the downlink channel, for example, the DMRS of the PDCCH or the DMRS of the physical downlink shared channel PDSCH, etc. The downlink control information can be DCI; the downlink configuration information can be radio resource control information RRC or media access control information MAC-CE, etc.

[0272] Based on the above scheme, the first communication device can determine the first search space and the second search space according to the fifth information, and when the first search space is used to detect the PDCCH in the process of detecting the PDCCH by the first communication device, the detection interval of the PDCCH is significantly improved, and / or the blind detection range when detecting the PDCCH is significantly reduced, so that the power consumption of the first communication device for detecting the PDCCH is significantly reduced, thereby reducing the overall power consumption of the first communication device.

[0273] The method provided by the application is described above, and the application further provides a communication device for implementing the functions described in the method embodiments.

[0274] It can be understood that the communication device comprises a hardware structure and / or software module corresponding to each function in order to implement the above functions.

The communication device 100 can be used to implement the functions of the first communication device or the second communication device described above.

[0277] In some embodiments, the communication device 100 can further comprise a storage module (not shown in FIG. 10) for storing program instructions and data.

[0278] In some embodiments, the transceiver module 1002, which can also be referred to as a transceiver unit, is used to implement the sending and / or receiving functions. The transceiver module 1002 can be composed of a transceiver circuit, a transceiver, a transceiver or a communication interface.

[0279] In some embodiments, the transceiver module 1002 can comprise a receiving module and a sending module, which are respectively used to perform the receiving and sending steps of the first communication device or the second communication device in the method embodiments described above, and / or are used to support other processes of the technologies described herein; the processing module 1001 can be used to perform the processing steps of the first communication device or the second communication device in the method embodiments described above, and / or is used to support other processes of the technologies described herein.

[0286] The above method embodiments involve all related content of each step, which can be referred to the function description of the corresponding function module, and will not be repeated here.

[0287] In this application, the communication apparatus 100 can be in the form of an integrated manner to present each function module. The "module" here can refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and a memory executing one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0288] In some embodiments, when the communication apparatus 100 in FIG. 10 is a chip or a chip system, the function / implementation process of the transceiver module 1002 can be implemented through an input / output interface (or a communication interface) of the chip or the chip system, and the function / implementation process of the processing module 1001 can be implemented through a processor (or a processing circuit) of the chip or the chip system.

[0289] Since the communication apparatus 100 provided by the embodiment can execute the above method, the technical effects that can be obtained by the communication apparatus 100 can refer to the above method embodiments, which will not be described here again.

[0290] As a possible product form, the first communication apparatus or the second communication apparatus described in the embodiments of the present application can be implemented using one or more field programmable gate arrays (FPGA), programmable logic devices (PLD), controllers, state machines, gate logic, discrete hardware components, any other suitable circuit, or any combination of circuits capable of performing the various functions described throughout the present application.

[0291] As another possible product form, the first communication apparatus or the second communication apparatus described in the embodiments of the present application can be implemented by a general bus architecture. For ease of illustration, refer to FIG. 11, which is a structural schematic diagram of a communication apparatus 1100 provided by an embodiment of the present application, the communication apparatus 1100 including a processor 1101 and a transceiver 1102. The communication apparatus 1100 can be a first communication apparatus, or a chip or a chip system therein. Alternatively, the communication apparatus 1100 can be a second communication apparatus, or a chip or a module therein. FIG. 11 only shows the main components of the communication apparatus 1100. In addition to the processor 1101 and the transceiver 1102, the communication apparatus can further include a memory 1103 and an input / output device (not shown in the figure).

[0292] Optionally, the processor 1101 is mainly used for processing communication protocols and communication data, and controlling the whole communication apparatus, executing a software program, processing data of the software program, so as to implement the method provided in the above method embodiments. The memory 1103 is mainly used for storing the software program and the data. The transceiver 1102 can include a radio frequency circuit and an antenna, the radio frequency circuit is mainly used for conversion between a baseband signal and a radio frequency signal and processing of the radio frequency signal. The antenna is mainly used for transceiving radio frequency signals in the form of electromagnetic waves. The input / output device, such as a touch screen, a display screen, a keyboard, etc., is mainly used for receiving data input by a user and outputting data to the user.

[0293] Optionally, the processor 1101, the transceiver 1102, and the memory 1103 can be connected through a communication bus.

[0294] When the communication device is powered on, the processor 1101 can read the software program in the memory 1103, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 1101 performs baseband processing on the data to be transmitted, and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal, and transmits the radio frequency signal in the form of electromagnetic wave through the antenna. When data is transmitted to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1101. The processor 1101 converts the baseband signal into data and processes the data.

[0295] In another implementation, the radio frequency circuit and the antenna can be arranged independently of the processor performing baseband processing, for example, in a distributed scenario, the radio frequency circuit and the antenna can be arranged remotely from the communication device.

[0296] In some embodiments, in hardware implementation, those skilled in the art can conceive that the above-mentioned communication device 100 can adopt the form of the communication device 1100 shown in FIG. 11.

[0297] As an example, the functions / implementation processes of the processing module 1001 in FIG. 10 can be realized by the processor 1101 in the communication device 1100 shown in FIG. 11 calling the computer execution instructions stored in the memory 1103. The functions / implementation processes of the transceiving module 1002 in FIG. 10 can be realized by the transceiver 1102 in the communication device 1100 shown in FIG. 11.

[0298] As another possible product form, the first communication device or the second communication device in the present application can adopt the constituent structure shown in FIG. 12, or include the components shown in FIG. 12. FIG. 12 is a constituent diagram of a communication device 1200 provided by the present application. The communication device 1200 can be the first communication device or a chip or system on chip in the first communication device; or can be the second communication device or a module or chip or system on chip in the second communication device.

[0299] As shown in FIG. 12, the communication device 1200 includes at least one processor 1201, and at least one communication interface (only one communication interface 1204 is shown in FIG. 12 as an example, and the processor 1201 is taken as an example for description). Optionally, the communication device 1200 can further include a communication bus 1202 and a memory 1203.

[0300] The processor 1201 can be a general purpose central processing unit (CPU), a general purpose processor, a network processing unit (NP), a digital signal processing (DSP), a microprocessor, a microcontroller, a PLD, or any combination thereof. The processor 1201 can also be other apparatuses with processing capabilities, such as a circuit, a device, or a software module, without limitation.

[0301] The communication bus 1202 is used to connect different components in the communication apparatus 1200, so that different components can communicate. The communication bus 1202 can be a peripheral component interconnect (PCI) bus or an extended industry standard architecture (EISA) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, only one thick line is shown in FIG. 12, but it does not mean that there is only one bus or only one type of bus.

[0302] The communication interface 1204 is used to communicate with other devices or communication networks. For example, the communication interface 1204 can be a module, a circuit, a transceiver, or any device capable of communication. Alternatively, the communication interface 1204 can also be an input / output interface in the processor 1201, used to realize the signal input and signal output of the processor.

[0303] The memory 1203 can be a device with storage function, used to store instructions and / or data. The instructions can be a computer program.

[0304] For example, the memory 1203 can be a read-only memory (ROM) or other type of static storage device that can store static information and / or instructions, or a random access memory (RAM) or other type of dynamic storage device that can store information and / or instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM), or other optical disk storage, optical disk storage (including compact disks, laser disks, optical disks, digital versatile disks, Blu-ray disks, etc.), magnetic disk storage medium, or other magnetic storage device, etc., without limitation.

[0305] It should be noted that the memory 1203 can exist independently of the processor 1201, or can be integrated with the processor 1201. The memory 1203 can be located in the communication device 1200, or can be located outside the communication device 1200, without limitation. The processor 1201 can be used to execute instructions stored in the memory 1203 to implement the method provided by the embodiments described below.

[0306] As an optional implementation, the communication device 1200 can further include an output device 1205 and an input device 1206. The output device 1205 communicates with the processor 1201 and can display information in various ways. For example, the output device 1205 can be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector, etc. The input device 1206 communicates with the processor 1201 and can receive user input in various ways.
