Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a communication method and apparatus. Background Art

[0002] In Release 18, the 3rd generation partnership project (3GPP) has been researching low power (LP) wake up signals (WUS) with the aim of evaluating the potential of terminals equipped with low power radios (LR) to reduce power consumption. Generally, even when a terminal is not transmitting or receiving any data, it consumes tens of milliwatts of power, which is called idle power consumption. This idle power consumption is caused by the fact that the terminal must regularly measure and detect potential LP-WUS. Among them, the LR will regularly measure and detect LP-WUS, and the main radio (MR) can be turned off when the LR is active and searching for potential LP-WUS signals. The LR can wake up the MR to transmit and receive data when a LP-WUS is detected.

[0003] However, each turn-on and turn-off of the MR has additional energy consumption. Among them, when the power amplifier (PA) of the MR is turned on, there is a power ramp-up, which brings a certain time delay and additional power consumption from zero to the steady state. Therefore, it is difficult to achieve an energy-saving effect by frequently waking up the MR. Summary of the Invention

[0004] This application provides a communication method and apparatus, aiming to reduce the power consumption of the communication device.

[0005] In a first aspect, a communication method is provided. This method can be executed by a first communication device or a chip / chip system. Among them, the first communication device can be a network device or a terminal device. In this method, the first communication device includes a first module and a second module, and the power consumption of the first module is lower than that of the second module. Among them, the first communication device receives a low power wake up signal, and the low power wake up signal instructs the first module to work or instructs the second module to work. The first communication device activates the first module or the second module to transmit and receive data.

[0006] Based on this solution, the network device instructs the first module of the communication device to work or instructs the second module of the communication device to work through the low power wake up signal. Compared with the related art in which all functions are executed by the second module, the number of times of waking up the second module can be reduced. Therefore, it is possible to avoid frequently waking up the second module and achieve the purpose of energy saving.

[0007] In a possible implementation, a first communication device receives first information, where the first information includes first configuration information and second configuration information. The first configuration information includes one or more of the transmission bandwidth for data transmission and reception based on a first module, frequency domain resources, the period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization. The second configuration information includes one or more of the transmission bandwidth for data transmission and reception based on a second module, frequency domain resources, the period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization.

[0008] Based on the above solution, since the capabilities and latency requirements of the first module and the second module are different, different configuration information is respectively configured for the first module and the second module through the first information, so that the first module and the second module can perform corresponding functions based on the configuration information.

[0009] In a second aspect, a communication method is provided. This method can be executed by a second communication device or a chip / chip system. Among them, the second communication device can be a network device or a terminal device. In this method, the second communication device determines a low-power wake-up signal, where the low-power wake-up signal indicates that a first module included in the communication device works or indicates that a second module included in the communication device works, and the power consumption of the first module is lower than that of the second module included in the communication device. The second communication device sends the low-power wake-up signal to the communication device.

[0010] In a possible implementation, the second communication device sends first information to the communication device, where the first information includes first configuration information and second configuration information. The first configuration information includes one or more of the transmission bandwidth for data transmission and reception based on a first module, frequency domain resources, the period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization. The second configuration information includes one or more of the transmission bandwidth for data transmission and reception based on a second module, frequency domain resources, the period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization.

[0011] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal instructs the first module to perform small data transmission (SDT). Based on the above solution, since the first module has a simple structure, a large data processing latency, and low power, it is suitable for use in small data transmission scenarios with low data volume and low latency sensitivity.

[0012] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal further includes an identifier of the first configuration information or an identifier of the second configuration information. Based on this solution, by indicating the configuration information adopted by the first module or the second module through the low-power wake-up signal, the communication device can activate the first module or the second module and perform corresponding functions based on the configuration information indicated by the low-power wake-up signal.

[0013] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal indicating the operation of the first module includes, when the first module receives data, the low-power wake-up signal indicating the time-domain resources of the downlink data channel carrying the data.

[0014] Based on this solution, the low-power wake-up signal can indicate the time-domain resources of the downlink data channel carrying the data, without the need for other indication information to indicate, which can reduce the power consumption caused by the communication device receiving other indication information.

[0015] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal further indicates one or more of the time-frequency resources of the feedback information of the hybrid automatic repeat request based on the data sent by the first module or the cyclic shift size of the feedback information of the hybrid automatic repeat request based on the data sent by the first module.

[0016] Based on this solution, by indicating information such as the time-domain resources or cyclic shift size of the feedback information through the low-power wake-up signal, without the need for other indication information to indicate, which can reduce the power consumption caused by the communication device receiving other indication information.

[0017] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal indicating the operation of the first module includes, when the first module sends data, the low-power wake-up signal indicating the time-domain resources of the uplink data channel carrying the data.

[0018] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal further indicates one or more of the modulation and coding strategy, transport block, or antenna port used by the first module for data transmission and reception.

[0020] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal further indicates one or more of the number of hybrid automatic repeat request processes, precoding matrix, or the number of bits occupied by the channel quality indication measurement results used by the first module for data transmission and reception.

[0021] Based on this solution, by using a low-power wake-up signal to indicate the number of bits occupied by the hybrid automatic repeat request process number, precoding matrix, or channel quality indication, the first module can perform corresponding functions based on the indication of the low-power wake-up signal, and it is different from the number of bits occupied by the measurement results of the hybrid automatic repeat request process number, precoding matrix, or channel quality indication of the second module, which can meet the capabilities of the first module.

[0022] In a possible implementation of the first aspect and the second aspect, when the low-power wake-up signal indicates the operation of the second module, the low-power wake-up signal also indicates the working duration of the second module. Based on this solution, by indicating the working duration of the second module, it is possible to prevent the second module from being in the wake-up state for a long time and reduce the power consumption of the communication device.

[0023] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal indicates the start time and end time of the first timer, and the timing duration of the first timer is the working duration of the second module. Among them, the timing duration of the first timer is the duration from the start time to the end time. Based on this solution, the working duration of the second module can be indicated by the timer.

The transceiver unit is used to receive a low-power wake-up signal, and the low-power wake-up signal indicates the operation of the first module included in the communication device or indicates the operation of the second module included in the communication device. The processing unit is used to activate the first module or the second module to transmit and receive data.

[0025] In a possible implementation, the transceiver unit is further used to receive first information, and the first information includes first configuration information and second configuration information.

The transceiver unit is used to send the low-power wake-up signal to the first communication device.

[0027] In a possible implementation, the transceiver unit is further configured to send first information to a first communication device, where the first information includes first configuration information and second configuration information. The first configuration information includes one or more of the transmission bandwidth for data transceiver based on a first module, frequency domain resources, the period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization.

[0056] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the following explains and describes the technical terms related to the embodiments of the present application.

[0057] 1) The low power wake up signal (LP-WUS) is used in multiple low power communication protocols, such as long range radio (LoRa), bluetooth, or wireless fidelity (WiFi). LP-WUS allows for the design and implementation of low power receivers, which helps reduce device power consumption. LP-WUS is very similar to WUS, which is sent based on the traditional Zadoff-Chu (ZC) sequence and the downlink control information (DCI) in format 2-6 of the physical downlink control channel (PDCCH). If WUS is detected, the paging message will continue to be decoded; otherwise, the device will return to the sleep state and wait for the next opportunity to receive WUS.

[0058] The technical solutions of the embodiments of this application can be applied to New Radio (NR) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, fifth generation communication systems (5 th generation, 5G), next generation wireless communication systems such as 6G, etc., which are not limited here.

[0059] Figure 1 It is a schematic diagram of the architecture of the communication system 1000 to which the embodiments of this application are applied. As Figure 1 shown, the communication system includes a radio access network 100. Among them, the radio access network 100 may include at least one network device (such as Figure 1 110a and / or 110b in Figure 1 ), and may also include at least one terminal device (such as at least one of 120a-120j in Figure 1This is only a schematic diagram. Other network devices may also be included in this communication system, such as wireless relay devices and wireless backhaul devices, which are not drawn in Figure 1 the figure.

[0060] A network device is a network-side device with wireless transceiver functions. The network device can be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices and is called a RAN device. For example, the network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it can also be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU) or a distributed unit (DU). Here, the CU completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete some or all of the functions of the physical layer. For specific descriptions of the above protocol layers, reference can be made to the relevant technical specifications of the 3rd generation partnership project (3GPP). The network device can be a macro base station (such as Figure 1 110a in Figure 1 ), or a micro base station or an indoor station (such as 110b in ), or a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the network device.

[0061] In another possible scenario, multiple RAN nodes cooperate to assist a terminal in achieving wireless access, and different RAN nodes respectively implement partial functions of a base station. For example, the RAN nodes can be a CU, a 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 provided, 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 included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0062] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, the CU can also be called an O-CU (open CU), the DU can also be called an O-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU. For the convenience of description, in this application, the CU, CU-CP, CU-UP, DU, and RU are used as examples for description. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0063] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device can also be referred to as a user equipment (UE), mobile station, mobile terminal, etc. Terminal devices can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, remote healthcare, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. Embodiments of this application do not limit the specific technologies and specific device forms adopted by terminal devices.

[0064] Network devices and terminal devices can be fixed in location or movable. Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed on airplanes, balloons, and artificial satellites in the air. Embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0065] The roles of network devices and terminal devices can be relative. For example, Figure 1 the helicopter or drone 120i in [description] can be configured as a mobile network device. For those terminal devices 120j that access the radio access network 100 through 120i, the terminal device 120i is a network device; but for the network device 110a, 120i is a terminal device, that is, the communication between 110a and 120i is through the radio air interface protocol. Of course, the communication between 110a and 120i can also be through the interface protocol between network devices. At this time, relative to 110a, 120i is also a network device. Therefore, network devices and terminal devices can both be uniformly referred to as communication devices. Figure 1 110a and 110b in [description] can be referred to as communication devices with network device functions. Figure 1 120a - 120j in [description] can be referred to as communication devices with terminal device functions.

[0066] In the embodiments of the present application, the functions of the network device can also be performed by a module (such as a chip) in the network device, or can be performed by a control subsystem including the functions of the network device. The control subsystem including the functions of the network device here can be a control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device can also be performed by a module (such as a chip or a modem) in the terminal device, or can be performed by a device including the functions of the terminal device. In the following, an example will be described in which the functions of the terminal device are performed by the terminal and the functions of the network device are performed by the base station.

[0067] With the development of 5G technology, the 5G network has higher and higher requirements for the capabilities of terminals. As the requirements for terminal capabilities increase, the hardware of the terminal will increase accordingly, and the power consumption of the terminal will inevitably increase. Compared with LTE terminals, the maximum power supported by 5G terminals is 29 dBm. Under typical services, such as comprehensive web browsing, instant messaging, games, or videos, etc., the communication power consumption of 5G terminals increases by more than 200% on average compared with LTE terminals. The long-term battery life of the terminal is an important aspect of the user experience and will affect the applicability of 5G terminals or services. Therefore, the long-term battery life of 5G terminals faces great challenges, and researching how to save the power consumption of 5G terminals is the key to solving this problem.

[0068] Referring to Figure 2 , the terminal may include a low power wake up radio (LR) and a main radio (MR). It can be understood that LR and MR can be integrated as logical function modules on the same processor (such as a chip), or LR and MR can be separate processors (such as chips) respectively. The power consumption of LR is lower than that of MR. In another example, the bandwidth of LR is also lower than that of MR. It should be noted that MR and LR are only shown as exemplary names. LR can also be called an auxiliary module, and MR can also be called a main module. The present application does not make specific limitations. In the embodiments of the present application, an example will be described in which LR is the first module and MR is the second module.

[0069] In Release 18, the 3rd generation partnership project (3GPP) has been researching on the low power (LP) wake up signal (WUS) with the aim of evaluating the potential of 5G terminals with low LR to reduce power consumption. Generally speaking, even when a 5G terminal does not send or receive any data, it will consume dozens of milliwatts of power, which is called idle power consumption. This idle power consumption is due to the fact that 5G terminals must regularly measure and detect potential LP-WUS. Among them, the LR will regularly measure and detect LP-WUS, and the MR can be turned off when the LR is active and searching for potential LP-WUS signals. The LR can wake up the MR to send and receive data when a LP-WUS is detected.

[0070] However, each turn-on and turn-off of the MR has additional energy consumption. Among them, when the power amplifier (PA) of the MR is turned on, there is a power ramp-up, which brings a certain time delay and additional power consumption from zero to the steady state. For example, when doing radio resource management (RRM) measurements, the LR can receive LP-WUS and wake up the MR for RRM measurements. After the measurements are completed, the MR can go to sleep. Another example is that after the LR receives LP-WUS, it can wake up the MR to receive and demodulate signals. In these processes, waking up the MR will generate additional power consumption. Therefore, it is difficult to achieve an energy-saving effect by frequently waking up the main module.

[0071] In view of this, an embodiment of the present application provides a communication method. In this method, the base station instructs the first module of the terminal to work or instructs the second module of the terminal to work through a low power wake up signal. The terminal can then wake up the first module or the second module to send and receive data. Compared with the related technology where all functions are executed by the MR, the number of times of waking up the MR can be reduced, so that frequent waking up of the MR can be avoided, achieving the purpose of energy saving.

[0072] See Figure 3 , which is an exemplary flowchart of a communication method provided by an embodiment of the present application, and may include the following operations. Figure 3 In the illustrated embodiment, the first communication device may include a first module and a second module, and the power consumption of the first module is lower than that of the second module. Figure 3 In the illustrated embodiment, the first communication device is taken as the terminal and the second communication device is taken as the base station for illustration.

[0073] S301: The base station sends a low power wake up signal to the terminal.

[0074] Correspondingly, the terminal receives the low power wake up signal from the base station.

[0075] In the embodiments of the present application, the low-power wake-up signal can be received by a low-power receiver, which helps to reduce the power consumption of the device. In the following, the low-power wake-up is taken as an example of LP-WUS for illustration.

[0076] Among them, LP-WUS indicates that the first module works or indicates that the second module works. For example, the low-power wake-up signal may carry first indication information (indicator), and the first indication information indicates that the first module works or the second module works. It can be understood that the first indication information may be a newly added field in the low-power wake-up signal, or the existing field of the low-power wake-up signal may be reused. The present application does not make specific limitations. The following is introduced in combination with Table 1.

[0077] Table 1: An example of first indication information

[0078] First indication information Content 0 First module 1 Second module

[0079] In Table 1, when the value of the first indication information is 0, it indicates that the first module works. When the value of the first indication information is 1, it indicates that the second module works. It can be understood that the correspondence between the value of the first indication information and the content in Table 1 is only shown as an example and does not constitute a limitation on the correspondence between the value of the first indication information and the content. Vice versa, when the value of the first indication information is 1, it can indicate that the first module works. When the value of the first indication information is 0, it can indicate that the second module works.

[0080] S302: Activate the first module or the second module to transmit and receive data.

[0081] In S301, the first module can receive LP-WUS and obtain the information indicated by LP-WUS after demodulation. When LP-WUS indicates that the first module works, the first module can be woken up based on LP-WUS, or can be activated or turned on, and perform transmission and reception work, such as performing data transmission and reception work or performing control information transmission and reception work, etc. For example, refer to Figure 4A, LP-WUS can instruct the first module to operate, LP-WUS can instruct the first module to receive the physical downlink control channel (PDCCH) and / or the physical downlink shared channel (PDSCH), or LP-WUS can instruct the first module to transmit the physical uplink shared channel (PUSCH) and / or the physical uplink control channel (PUCCH), etc.

[0082] It can be understood that the functions performed by the first module indicated by the above LP-WUS are only shown as examples. LP-WUS can also instruct the first module to perform other functions, such as sensing, channel quality measurement, uplink positioning, downlink positioning, radio resource management (RRM) measurement and other functions, which are not specifically limited in this application. It can be understood that the functions performed by LP-WUS instructing the first module can be divided according to different channels, according to uplink and downlink, or according to specific functions.

[0083] For example, due to the simple structure, large data processing delay and low power of the first module, it is suitable for use in small data transmission (SDT) scenarios with low data volume and insensitive delay. LP-WUS can instruct the first module to operate and instruct the first module to perform SDT. Optionally, LP-WUS can also indicate the modulation and coding scheme (MCS) used for data transmission. The first module can use a low code rate for data transmission, such as 16 quadrature amplitude modulation (QAM).

[0084] Optionally, while the first module saves power consumption and energy consumption, it brings the problem of coverage priority. Therefore, how to enhance coverage has become a research issue. Generally, by increasing the maximum number of data retransmissions or using a single subcarrier for transmission during data sending and data receiving, the power spectral density is improved. Using the first module usually makes data sending and data receiving work on a smaller bandwidth and is more energy-efficient.

[0085] When the LP-WUS indicates that the second module works, the first module can indicate the second module to work. For example, the first module can send the obtained information to the second module, and the second module can be woken up based on the LP-WUS, or can be activated or can be turned on, and perform transceiver work, such as performing data transceiver work or performing control information transceiver work, etc. For example, refer to Figure 4B , the LP-WUS can indicate the second module to work, the LP-WUS can indicate the second module to receive PDCCH and / or PDSCH, or the LP-WUS can indicate the second module to send PUSCH and / or PUCCH, etc.

[0086] It can be understood that the functions performed by the second module indicated by the above LP-WUS are only shown as examples. The LP-WUS can also indicate the second module to perform other functions, such as channel quality measurement, data sending, data receiving, data initial transmission, data retransmission and other functions, which are not specifically limited in this application. It can be understood that the functions performed by the LP-WUS indicating the second module can be divided according to different channels, according to uplink and downlink, or according to specific functions.

[0087] In a possible implementation manner, the first module usually has the characteristics of low rate, low bandwidth, and low power consumption, which means low processing complexity. Therefore, in the embodiments of this application, different configuration information can be configured according to the capabilities and latency requirements of the first module and the second module. For example, the first configuration information can be configured for the first module, and the second configuration information can be configured for the second module.

[0088] Among them, the first configuration information may include one or more of transmission bandwidth, frequency domain resources, the period of the synchronization signal block (SSB) for time-frequency domain synchronization, or the number of SSBs. Similarly, the second configuration information may include one or more of transmission bandwidth, frequency domain resources, the period of the SSB for time-frequency domain synchronization, or the number of SSBs.

[0089] It can be understood that the first configuration information and the second configuration information can be predefined by the protocol or can be indicated by the base station. For example, if the first configuration information and the second configuration information are indicated by the base station, the base station can send the first information to the terminal, and the first configuration information and / or the second configuration information can be carried in the first information. Among them, the first information can be radio resource control (RRC) signaling, such as RRC reconfiguration signaling, which is not specifically limited in this application. In a possible case, the LP-WUS can include an identifier of the first configuration information or an identifier of the second configuration information, that is, the LP-WUS can indicate which configuration information to use for transceiver operations.

[0090] In the embodiments of this application, the transmission bandwidth in the first configuration information includes a candidate bandwidth part (BWP) or a BWP. It can be understood that since the operating bandwidth of the first module is smaller, the candidate BWP included in the first configuration information is less than the candidate BWP included in the second configuration information. Similarly, the BWP included in the first configuration information is less than the BWP included in the second configuration information.

[0091] In one example, the SSB period included in the first configuration information can be different from the SSB period included in the second configuration information. Similarly, the number of SSBs included in the first configuration information can be different from the number of SSBs included in the second configuration information. For example, due to the characteristics of low rate, low bandwidth, and low power consumption of the first module, the SSB period included in the first configuration information can be greater than the SSB period included in the second configuration information, and the number of SSBs included in the first configuration information can be less than the number of SSBs included in the second configuration information.

[0092] In another example, the frequency-domain resources included in the first configuration information can be indicated by a resource block group (RBG). Among them, a larger RBG size can be configured to reduce the bit overhead of the RBG indication information. For example, the RBG size included in the first configuration information is greater than the RBG size indicated by the RBG included in the second configuration information. Optionally, the LP-WUS can carry indication information for indicating the RBG, that is, the base station can indicate which RBG to use through the LP-WUS. The following is described in conjunction with Table 2.

[0093] Table 2: An example of an RBG

[0094] BWP size Configuration 1 Configuration 2 Configuration 3 1～36 2 4 8 37～72 4 8 16 73～144 8 16 32 145～275 16 16 32

[0095] Table 2 shows an example of RBG in the related art. When the BWP size is from 1 to 36, Configuration 1 can indicate that the RBG size is 2 RBs. Then, when the BWP size is from 1 to 36, there are at most 18 RBGs, that is, 18 bits are required to indicate the BWP bandwidth. For example, the indication can be "100000000000000000" to represent activating 2 RBs for communication. Similarly, when the BWP size is from 37 to 72, Configuration 1 can indicate that the RBG size is 4 RBs. Then, there are at most 18 RBGs in this BWP, that is, 18 bits are required to indicate the BWP bandwidth. For example, the indication can be "100000000000000000" to represent activating 4 RBs for communication, and so on.

[0096] Referring to Table 3, in the embodiment of the present application, a larger RBG size can be defined, that is, a larger number of RBs can be included in one RBG, so as to reduce the maximum number of RBGs included in the BWP and achieve a reduction in the bit overhead of the indication information of the RBG.

[0097] Table 3: An example of an RBG

[0098] BWP size Configuration X 1～36 16 37～72 16 73～144 32 145～275 64

[0099] In Table 3, when the BWP size is from 1 to 36, Configuration X can indicate that the RBG size is 16 RBs. Then, at most 3 RBGs can be included in this BWP, and 3 bits are required to indicate the BWP bandwidth. For example, the indication can be "100" to represent activating the first 16 RBs for communication.

[0100] In another possible implementation, when performing DCI blind detection in the PDCCH, when the first module performs DCI blind detection, the first module can be configured with an aggregation level of non-carrier coverage extension (CCE) different from that of the second module, a control resource set (CORESET) smaller than that of the second module when the second module performs DCI blind detection, and a search space smaller than that of the second module when the second module performs DCI blind detection to reduce the number of PDCCH blind detections and power consumption.

[0101] In yet another possible implementation, when sending data, it is necessary to configure one or more of a time domain resource, MCS, transport block (TB), or antenna port different from those of the second module in the DCI for the first module. The following is an introduction.

[0102] 1. Time-domain resource configuration information: The first module has low energy consumption and large processing delay. Therefore, a new list (table) of time-domain resource configuration information can be defined for the first module to indicate the time-domain resources for blind detection of DCI. Among them, the first module is associated with a list of time-domain resource configuration information, and the second module is associated with a list of time-domain configuration information. The base station can use LP-WUS to indicate which time-domain resource configuration information in the list to select.

[0103] For example, the time-domain resource configuration information may include one or more of K0, K1, or K2. Refer to Figure 5 , where K0 represents the time-domain interval from receiving DCI to scheduling PDSCH, K1 represents the time-domain interval from starting to send PDSCH to sending an acknowledgement (ACK) or non-acknowledgement (NACK), and K2 represents the time-domain interval from receiving DCI to scheduling uplink PUSCH.

[0104] 2. MCS: The first module operates in a low-power state and usually does not require high code rates and high-order modulation. Therefore, a new MCS list can be defined for the first module. For example, the maximum MCS configuration for data transmission is 16QAM. The base station can use LP-WUS to indicate which MCS in the MCS list to select.

[0105] 3. TB: The base station can configure only one TB for the first module to transmit, reducing the size of DCI.

[0106] 4. Antenna port: The base station can configure only a single-stream port or a dual-stream port for the first module, reducing the size of DCI.

[0107] In the embodiments of this application, when LP-WUS indicates that the first module works and indicates that the first module performs SDT, the rules for the uplink control information (UCI) sent by the first module and the UCI indicated are different from those sent by the second module.

[0108] For example, the processing capacity of the first module is limited and usually can only support a limited number of hybrid auto repeat request (HARQ) processes. In one possible case, when using the first module to receive data, the base station can use LP-WUS to indicate that the number of HARQ processes is 2 or a range, such as 2 - 4.

[0109] For another example, the uplink feedback of the first module usually does not need to support high-rank transmission. The base station can use LP-WUS to indicate a precoding matrix indicator (PMI) that supports a precoding matrix with rank ≤ 2, reducing the number of feedback bits.

[0110] For another example, the channel quality indicator (CQI) carried in UCI is usually 5 bits. In the embodiments of the present application, the base station can use LP-WUS to indicate that the number of bits occupied by CQI is 2 bits, reducing the number of feedback bits.

[0111] For another example, in the embodiments of the present application, the time-frequency domain resources of PUCCH can be configured for the first module, and LP-WUS can be used to indicate the time-frequency domain resources of PUCCH. For example, a new table can be added to describe the PUCCH symbol position, frequency domain offset, and cyclic shift size, and LP-WUS can be used to indicate which item in the table is used for the PUCCH symbol position, frequency domain offset, and cyclic shift size. Alternatively, for the time-frequency domain resources of PUCCH of the first module, the table of PUCCH time-frequency domain resources in related technologies can also be reused, and LP-WUS can be used to indicate which item in the table is used for the PUCCH symbol position, frequency domain offset, and cyclic shift size.

[0112] For another example, since scheduling PUSCH requires additional signaling overhead, the base station can use LP-WUS to indicate that UCI is reported on the PUCCH channel.

[0113] In the embodiments of the present application, LP-WUS can indicate the operation of the second module, such as indicating that the second module performs data transmission and reception. For example, big data can be sent and received through the second module.

[0114] In a possible implementation, LP-WUS can indicate the working duration of the second module. For example, LP-WUS can indicate the start time and end time of the second module to indicate the working duration of the second module. For another example, the first information can indicate the start time and end time of a timer, and the duration between the start time and the end time can be understood as the working duration of the second module. For example, the start time can be the time when the second module is activated. Optionally, LP-WUS can also indicate the update rule for the start time or end time of the timer. For example, the timer can be terminated in advance if no DCI is received within a certain period of time.

[0115] See Figure 6, LP-WUS instructs the second module to work, and LP-WUS indicates a timer, as well as the start time and end time of the timer. The second module can be activated and the timer can be started. If DCI is received within a period of time, the second module can blindly detect DCI and demodulate DCI to obtain the information scheduled by DCI. The second module can perform corresponding functions based on the scheduling of DCI, such as data transmission or data reception, etc. And at the end time of the timer, the timer is terminated and closed or put into sleep. If DCI is not received within a period of time, the second module can terminate the timer in advance and close or put into sleep to achieve the purpose of energy saving.

[0116] Optionally, LP-WUS can indicate whether there is DCI within a period of time. For example, LP-WUS can carry 1-bit indication information. When the value of the 1-bit indication information is 0, it indicates that there is DCI within a period of time. When the value of the 1-bit indication information is 1, it indicates that there is no DCI within a period of time. Vice versa, when the value of the 1-bit indication information is 1, it indicates that there is DCI within a period of time. When the value of the 1-bit indication information is 0, it indicates that there is no DCI within a period of time.

[0117] If LP-WUS indicates that there is no DCI within a period of time, the second module can terminate the timer in advance and close or put into sleep to achieve the purpose of energy saving.
