Communication method and device
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 15, 2023, with application number 202311733802.9 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field
[0003] The present application relates to the field of wireless communication technology, and in particular to a communication method and device. Background Art
[0004] In R18, the 3rd Generation Partnership Project (3GPP) conducted research on low power (LP) wake-up signals (WUS) with the aim of evaluating the potential for reducing power consumption of terminals equipped with low power radios (LR). Generally speaking, even if a terminal does not send or receive 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 periodically measure and detect potential LP-WUS. Among them, LR will periodically measure and detect LP-WUS, and the main radio (MR) can be turned off when LR is active and searching for potential LP-WUS signals. LR can wake up MR to send and receive data when LP-WUS is detected.
[0005] However, each time the MR is turned on and off, additional energy is consumed. The MR's power amplifier (PA) requires a power ramp when it is turned on, which results in a certain delay and additional power consumption as the power transitions from zero to a steady state. Therefore, frequently waking up the MR is unlikely to achieve energy savings.
[0006] Summary of the Invention
[0007] The present application provides a communication method and device to reduce the power consumption of the communication device.
[0008] In a first aspect, a communication method is provided. The method can be performed by a first communication device or a chip / chip system. The first communication device can be a network device or a terminal device. In the method, the first communication device includes a first module and a second module, and the power consumption of the first module is lower than the power consumption of the second module. The first communication device receives a low-power wake-up signal, which instructs the first module to operate or instructs the second module to operate. The first communication device activates the first module or the second module to transmit and receive data.
[0009] Based on this solution, the network device uses a low-power wake-up signal to instruct the first module of the communication device to operate, or to instruct the second module of the communication device to operate. Compared with the related art where all functions are performed by the second module, the number of times the second module needs to be woken up can be reduced, thus avoiding frequent wake-up of the second module and achieving energy conservation.
[0010] In one 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 a transmission bandwidth for data received and sent by the first module, frequency domain resources, a period of a synchronization signal block used for time-frequency domain synchronization, or the number of synchronization signal blocks used for time-frequency domain synchronization. The second configuration information includes one or more of a transmission bandwidth for data received and sent by the second module, frequency domain resources, a period of a synchronization signal block used for time-frequency domain synchronization, or the number of synchronization signal blocks used for time-frequency domain synchronization.
[0011] 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 configured for the first module and the second module respectively through the first information, so that the first module and the second module can perform corresponding functions based on the configuration information.
[0012] In a second aspect, a communication method is provided. The method can be performed by a second communication device or a chip / chip system. 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 instructs a first module included in the communication device to operate or instructs a second module included in the communication device to operate, and the power consumption of the first module is lower than the power consumption of the second module included in the communication device. The second communication device sends the low-power wake-up signal to the communication device.
[0013] In one 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 a transmission bandwidth for data received and sent by the first module, frequency domain resources, a 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 a transmission bandwidth for data received and sent by the second module, frequency domain resources, a period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization.
[0014] In a possible implementation of the first and second aspects, 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, large data processing delay and low power consumption, it is suitable for use in small data transmission scenarios with low data volume and insensitive to delay.
[0015] In one possible implementation of the first and second aspects, 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, the low-power wake-up signal indicates the configuration information used by the first module or the configuration information used by the second module, and the communication device can activate the first module or the second module and perform a corresponding function based on the configuration information indicated by the low-power wake-up signal.
[0016] In a possible implementation of the first and second aspects, when the low-power wake-up signal instructs the first module to operate, including receiving data based on the first module, the low-power wake-up signal indicates the time domain resources of the downlink data channel carrying the data.
[0017] Based on this solution, the low-power wake-up signal can indicate the time domain resources of the downlink data channel that carries data, and does not require other indication information to indicate, which can reduce the power consumption caused by the communication device receiving other indication information.
[0018] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal also 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.
[0019] Based on this solution, the time domain resource or cyclic shift size of the feedback information is indicated by a low-power wake-up signal, and no other indication information is needed to indicate it, which can reduce the power consumption caused by the communication device receiving other indication information.
[0020] In a possible implementation manner of the first and second aspects, when the low-power wake-up signal indicates that the operation of the first module includes sending data based on the first module, the low-power wake-up signal indicates the time domain resources of the uplink data channel carrying the data.
[0021] In a possible implementation manner of the first aspect and the second aspect, the low-power wake-up signal further indicates one or more of a modulation and coding strategy, a transmission block, or an antenna port used by the first module to send and receive data.
[0022] Based on this solution, the modulation and coding strategy, transmission block or antenna port and other information of the first module are indicated by a low-power wake-up signal, which is different from the second module and can meet the capabilities of the first module.
[0023] In a possible implementation of the first aspect and the second aspect, the low-power wake-up signal also indicates one or more of the number of hybrid automatic repeat request processes used for sending and receiving data by the first module, the precoding matrix, or the number of bits occupied by the channel quality indication measurement result.
[0024] Based on this solution, the number of bits occupied by the hybrid automatic repeat request process, the precoding matrix or the channel quality indication is indicated by a low-power wake-up signal, so that the first module can perform the corresponding function based on the indication of the low-power wake-up signal, and the number of bits occupied by the hybrid automatic repeat request process, the precoding matrix or the channel quality indication measurement result is different from that of the second module, which can meet the capabilities of the first module.
[0025] In one possible implementation of the first and second aspects, when the low-power wake-up signal instructs the second module to operate, the low-power wake-up signal also indicates the operating duration of the second module. Based on this solution, by indicating the operating duration of the second module, the second module can be prevented from being in the awake state for a long time, thereby reducing power consumption of the communication device.
[0026] In a possible implementation of the first and second aspects, the low-power wake-up signal indicates the start and end times of the first timer, and the timing duration of the first timer is the operating duration of the second module. The timing duration of the first timer is the duration from the start time to the end time. Based on this solution, the operating duration of the second module can be indicated by the timer.
[0027] In a third aspect, a communication device is provided, comprising a processing unit and a transceiver unit.

The transceiver unit is configured to send the low-power wake-up signal to the first communication device.
[0030] In one possible implementation, the transceiver unit is further configured to send first information to the first communication device, where the first information includes first configuration information and second configuration information, the first configuration information including one or more of a transmission bandwidth for data received and transmitted by the first module, frequency domain resources, a 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 a transmission bandwidth for data received and transmitted by the second module, frequency domain resources, a period of a synchronization signal block for time-frequency domain synchronization, or the number of synchronization signal blocks for time-frequency domain synchronization.

[0059] In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained and illustrated below.
[0060] 1) Low power wake up signal (LP-WUS), which is used in multiple low power communication protocols, such as long range radio (LoRa), Bluetooth or wireless fidelity (WiFi). LP-WUS allows the design and implementation of low power receivers, which helps reduce device power consumption. LP-WUS is very similar to WUS. WUS is based on the traditional Zadoff-Chu (ZC) sequence and downlink control information (DCI) in formats 2-6 in the physical downlink control channel (PDCCH). If WUS is detected, the device will continue to decode the paging message, otherwise it will return to sleep and wait for the next opportunity to receive WUS.
[0061] The technical solutions of the embodiments of the present 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) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, and fifth generation communication systems (5G) and 5G th generation, 5G), and next-generation wireless communication systems, such as 6G, are not restricted here.
[0062] FIG1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in FIG1 , the communication system includes a wireless access network 100. The wireless access network 100 may include at least one network device (such as 110a and / or 110b in FIG1 ) and may also include at least one terminal device (such as at least one of 120a-120j in FIG1 ). The terminal device is connected to the access network device wirelessly, and the access network device is connected to the core network device wirelessly or by wire. Terminal devices and network devices may be connected to each other by wire or by wireless. FIG1 is only a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1 .
[0063] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities for terminal devices, and is called a RAN device. For example, a network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU here 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 the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.
[0064] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).
[0065] In different systems, CU (or CU-CP and CU-UP), DU or 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, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of 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.
[0066] A terminal device is a user-side device with wireless transceiver capabilities. A terminal device may also be referred to as user equipment (UE), a mobile station, a mobile terminal, etc. Terminal devices can be widely used 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, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home appliance, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.
[0067] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.
[0068] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. To terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, to network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal device functionality.
[0069] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device function. The control subsystem that includes the network device function here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or by a device that includes the terminal device function. In the following, the example in which the terminal device function is performed by the terminal and the network device function is performed by the base station is described.
[0070] With the development of 5G technology, 5G networks are placing increasingly higher demands on terminal capabilities. This increased demand for terminal capabilities necessitates a corresponding increase in terminal hardware, which inevitably increases terminal power consumption. Compared to LTE terminals, 5G terminals support a maximum power of 29dBm. Under typical services, such as comprehensive web browsing, instant messaging, gaming, or food consumption, 5G terminal communication power consumption increases by an average of over 200% compared to LTE terminals. Terminal battery life is a crucial aspect of user experience and impacts the suitability of 5G terminals or services. Therefore, ensuring the battery life of 5G terminals faces significant challenges, and research on how to reduce 5G terminal power consumption is key to addressing this issue.
[0071] Referring to Figure 2, the terminal may include a low power wake up radio (LR) and a main radio (MR). It will be understood that the LR and MR may be integrated as logical function modules on the same processor (e.g., a chip), or the LR and MR may be independent processors (e.g., chips). The power consumption of the LR is lower than that of the MR. In another example, the bandwidth of the LR is also lower than that of the MR. It should be noted that MR and LR are shown only as exemplary names, the LR may also be referred to as an auxiliary module, and the MR may also be referred to as a main module, which is not specifically limited in this application. In the embodiment of the present application, the LR is taken as the first module and the MR is taken as the second module as an example for illustration.
[0072] In R18, the 3rd generation partnership project (3GPP) conducted research on low power (LP) wake-up signals (WUS) with the aim of evaluating the potential for reducing power consumption in 5G terminals equipped with low LR. Generally speaking, even if a 5G terminal does not send or receive 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 5G terminal must periodically measure and detect potential LP-WUS. Among them, LR will periodically measure and detect LP-WUS, and MR can be turned off when LR is active and searching for potential LP-WUS signals. LR can wake up MR to send and receive data when LP-WUS is detected.
[0073] However, each time the MR is turned on and off, additional energy is consumed. The power amplifier (PA) of the MR is turned on with a power ramp, which brings a certain delay and additional power consumption when the power changes from zero to a stable state. For example, when performing radio resource management (RRM) measurements, the LR can receive LP-WUS and wake up the MR to perform RRM measurements. After the measurement is completed, the MR can go to sleep. For another example, after the LR receives LP-WUS, it can wake up the MR to receive and demodulate the signal. In these processes, waking up the MR will generate additional power consumption. Therefore, it is difficult to achieve energy saving by frequently waking up the main module.
[0074] In view of this, an embodiment of the present application provides a communication method. In this method, a base station instructs a terminal's first module to operate or a terminal's second module to operate via a low-power wake-up signal. The terminal can then wake up the first module or the second module to transmit and receive data. Compared to related technologies in which all functions are performed by the MR, this method can reduce the number of MR wake-ups, thereby avoiding frequent MR wake-ups and achieving energy conservation.
[0075] Referring to Figure 3, which is an exemplary flow chart of a communication method provided in an embodiment of the present application, the method may include the following operations. In the embodiment shown in Figure 3, the first communication device may include a first module and a second module, and the power consumption of the first module is lower than the power consumption of the second module. In the embodiment shown in Figure 3, the first communication device is a terminal and the second communication device is a base station.
[0076] S301: The base station sends a low-power wake-up signal to the terminal.
[0077] Correspondingly, the terminal receives a low-power wake-up signal from the base station.
[0078] In the embodiment of the present application, the low power consumption wake-up signal can be received by a low power receiver, which helps to reduce the power consumption of the device. The following description takes the low power consumption wake-up signal LP-WUS as an example.
[0079] Among them, LP-WUS indicates that the first module is working or that the second module is working. For example, the low-power wake-up signal may carry first indication information (indicator), and the first indication information indicates that the first module is working or the second module is working. It is understandable that the first indication information may be a newly added field in the low-power wake-up signal, or may reuse an existing field of the low-power wake-up signal, which is not specifically limited in this application. The following is an introduction in conjunction with Table 1.
[0080] Table 1: Example of first indication information
[0081] In Table 1, when the value of the first indication information is 0, it indicates that the first module is operating, and when the value of the first indication information is 1, it indicates that the second module is operating. It should be understood that the correspondence between the values of the first indication information and the content in Table 1 is only for example purposes and does not constitute a limitation on the correspondence between the values of the first indication information and the content. Conversely, when the value of the first indication information is 1, it can indicate that the first module is operating, and when the value of the first indication information is 0, it can indicate that the second module is operating.
[0082] S302: Activate the first module or the second module to send and receive data.
[0083] In S301, the first module may receive an LP-WUS, and after demodulation, obtain information indicated by the LP-WUS. When the LP-WUS instructs the first module to operate, the first module may wake up, or be activated, or be turned on based on the LP-WUS, and perform transceiver operations, such as performing data transmission and reception operations or performing control information transmission and reception operations. For example, referring to FIG4A , the LP-WUS may instruct the first module to operate, and the LP-WUS may instruct the first module to receive a physical downlink control channel (PDCCH) and / or a physical downlink shared channel (PDSCH), or the LP-WUS may instruct the first module to transmit a physical uplink shared channel (PUSCH) and / or a physical uplink control channel (PUCCH), etc.
[0084] It is understood that the functions performed by the first module indicated by the above LP-WUS are only shown as examples. The LP-WUS can also instruct the first module to perform other functions, such as perception, channel quality measurement, uplink positioning, downlink positioning, radio resource management (RRM) measurement, etc., which are not specifically limited in this application. It is understood that the functions performed by the first module indicated by the LP-WUS can be divided according to different channels, according to uplink and downlink divisions, or according to specific functions.
[0085] For example, due to the simple structure of the first module, large data processing delay and low power, it is suitable for use in small data transmission (SDT) scenarios with low data volume and insensitivity to delay. LP-WUS can instruct the first module to work 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-bit quadrature amplitude modulation (QAM).
[0086] While the first module saves power and energy, it also increases coverage. Therefore, improving coverage has become a research issue. This is typically achieved by increasing the maximum number of data retransmissions or using a single subcarrier for transmission during data transmission and reception, thereby improving power spectral density. Using the first module typically allows data transmission and reception to operate over a smaller bandwidth, resulting in greater energy efficiency.
[0087] When the LP-WUS instructs the second module to operate, the first module may instruct the second module to operate. For example, the first module may send acquired information to the second module, and the second module may be awakened, activated, or turned on based on the LP-WUS and perform transceiver operations, such as data transmission and reception or control information transmission and reception. For example, referring to FIG4B , the LP-WUS may instruct the second module to operate, the LP-WUS may instruct the second module to receive PDCCH and / or PDSCH, or the LP-WUS may instruct the second module to transmit PUSCH and / or PUCCH, etc.
[0088] It is understood that the functions performed by the second module as instructed by the LP-WUS are merely exemplary. The LP-WUS may also instruct the second module to perform other functions, such as channel quality measurement, data transmission, data reception, initial data transmission, data retransmission, and other functions, which are not specifically limited in this application. It is understood that the functions performed by the second module as instructed by the LP-WUS may be divided according to different channels, according to uplink and downlink, or according to specific functions.
[0089] In one possible implementation, the first module typically has low speed, low bandwidth, and low power consumption, which means low processing complexity. Therefore, in embodiments of the present application, different configuration information can be configured for the first and second modules based on their capabilities, latency requirements, etc. For example, first configuration information can be configured for the first module, and second configuration information can be configured for the second module.
[0090] The first configuration information may include one or more of the following: transmission bandwidth, frequency domain resources, a period of a 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 the following: transmission bandwidth, frequency domain resources, a period of an SSB for time-frequency domain synchronization, or the number of SSBs.
[0091] 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 information can carry the first configuration information and / or the second configuration information. Among them, the first information can be a radio resource control (RRC) signaling, such as an RRC reconfiguration (RRCreconfiguration) signaling, which is not specifically limited in this application. In one 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 sending and receiving.
[0092] In the embodiment of the present application, the transmission bandwidth in the first configuration information includes a candidate bandwidth part (wandwidth part, BWP) or BWP. It is understandable that, because the operating bandwidth of the first module is smaller, the candidate BWP included in the first configuration information is smaller than the candidate BWP included in the second configuration information. Similarly, the BWP included in the first configuration information is smaller than the BWP included in the second configuration information.
[0093] In one example, the SSB period included in the first configuration information may be different from the SSB period included in the second configuration information. Similarly, the number of SSBs included in the first configuration information may be different from the number of SSBs included in the second configuration information. For example, because the first module has the characteristics of low speed, low bandwidth, and low power consumption, the SSB period included in the first configuration information may be greater than the SSB period included in the second configuration information, and the number of SSBs included in the first configuration information may be less than the number of SSBs included in the second configuration information.
[0094] In another example, the frequency domain resources included in the first configuration information can be indicated by a resource block group (RBG). 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 larger 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.
[0095] Table 2: An example of an RBG
[0096] Table 2 shows an example of RBGs in the related art. When the BWP size is 1 to 36, Configuration 1 can indicate that the RBG size is 2 RBs. Therefore, when the BWP size is 1 to 36, there are a maximum of 18 RBGs, which requires 18 bits to indicate the BWP bandwidth. For example, the indication can be "1000000000000000000" to indicate that two RBs are activated for communication. Similarly, when the BWP size is 37 to 72, Configuration 1 can indicate that the RBG size is 4 RBs. Therefore, there are a maximum of 18 RBGs within the BWP, which requires 18 bits to indicate the BWP bandwidth. For example, the indication can be "1000000000000000000" to indicate that four RBs are activated for communication, and so on.
[0097] Referring to Table 3, a larger RBG size can be defined in the embodiment of the present application, that is, more RBs can be included in one RBG to reduce the maximum number of RBGs included in the BWP, thereby reducing the bit overhead of the RBG indication information.
[0098] Table 3: An example of an RBG
[0099] In Table 3, when the BWP size is 1 to 36, configuration X can indicate that the RBG size is 16 RBs. Then, the BWP can contain a maximum of 3 RBGs, and 3 bits are required to indicate the BWP bandwidth. For example, the indication can be "100" to activate the first 16 RBs for communication.
[0100] In another possible implementation, when performing DCI blind detection in PDCCH, when the first module performs DCI blind detection, the first module can be configured with a non-carrier coverage extension (CCE) aggregation level different from that of the second module, a control resource set (CORESET) smaller than that when the second module performs DCI blind detection, and a search space (search space) smaller than that when the second module performs DCI blind detection to reduce the number of PDCCH blind detections and energy consumption.
[0101] In another possible implementation, when data is transmitted, it is necessary to configure one or more of the following in the DCI: time domain resources, MCS, transport block (TB), or antenna port for the first module that are different from those for the second module. This is described below.
[0102] 1. Time Domain Resource Configuration Information: The first module has low energy consumption and high processing latency. Therefore, a new time domain resource configuration information table can be defined for the first module to indicate the time domain resources for blind DCI detection. The first module is associated with one time domain resource configuration information table, and the second module is associated with another time domain configuration information table. The base station can use LP-WUS to indicate which time domain resource configuration information in the table to select.
[0103] For example, the time domain resource configuration information may include one or more of K0, K1, or K2. Referring to Figure 5, K0 represents the time domain interval from the start of DCI reception to the scheduling of PDSCH, K1 represents the time domain interval from the start of PDSCH transmission to the sending of acknowledgment (ACK) or non-acknowledgement (NACK), and K2 represents the time domain interval from the start of DCI reception to the scheduling of uplink PUSCH.
[0104] 2. MCS: The first module operates in a low-power state and generally does not require high bit rates and high-order modulation. Therefore, a new MCS list can be defined for the first module. For example, the maximum MCS for data transmission can be configured as 16QAM. The base station can use the 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 for transmission to reduce the DCI size.
[0106] 4. Antenna port: The base station can configure only a single-stream port or a dual-stream port for the first module to reduce the DCI size.
[0107] In the embodiment of the present application, the LP-WUS instructs the first module to work and instructs the first module to perform SDT, and the uplink control information (UCI) sent by the first module and the rule indicating the UCI are different from those sent by the second module.
[0108] For example, the first module has limited processing capabilities and can typically only support a limited number of hybrid automatic repeat request (HARQ) processes. In one possible scenario, when using the first module to receive data, the base station may indicate through the LP-WUS that the number of HARQ processes is 2 or a range, such as 2 to 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 that the precoding matrix indicator (PMI) supports precoding matrices with rank ≤ 2, thereby reducing the number of feedback bits.
[0110] For another example, the continuous quality indicator (CQI) carried in the UCI is usually 5 bits. In the embodiment of the present application, the base station can use LP-WUS to indicate that the bits occupied by the CQI are 2 bits, thereby reducing the number of feedback bits.
[0111] For another example, in an embodiment of the present application, the time-frequency domain resources of the PUCCH can be configured for the first module, and the time-frequency domain resources of the PUCCH can be indicated by LP-WUS. For example, a new table is added to describe the PUCCH symbol position, frequency domain offset and cyclic shift size, and the LP-WUS is used to indicate which PUCCH symbol position, frequency domain offset and cyclic shift size in the table is used. Alternatively, for the time-frequency domain resources of the PUCCH of the first module, the table of PUCCH time-frequency domain resources in the related technology can also be reused, and the LP-WUS is used to indicate which PUCCH symbol position, frequency domain offset and cyclic shift size in the table is used.
[0112] For another example, since scheduling the PUSCH requires additional signaling overhead, the base station may indicate that the UCI is reported on the PUCCH channel through the LP-WUS.
[0113] In the embodiment of the present application, the LP-WUS can instruct the second module to work, such as instructing the second module to send and receive data. For example, large data can be sent and received by the second module.
[0114] In one possible implementation, the LP-WUS may indicate the operating duration of the second module. For example, the LP-WUS may indicate the start time and the shutdown time of the second module to indicate the operating duration of the second module. For another example, the first information may indicate the start time of the timer and the end time of the timer, and the duration between the start time and the end time may be understood as the operating duration of the second module. For example, the start time may be the time when the second module is activated. Optionally, the LP-WUS may also indicate the update rules for the start time or the end time of the timer. For example, if no DCI is received within a period of time, the timer may be terminated early.
[0115] Referring to Figure 6, LP-WUS indicates that the second module is working, 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 start the timer. If DCI is received within a period of time, the second module can blindly detect DCI and demodulate DCI to obtain DCI scheduling information. The second module can perform corresponding functions based on the DCI scheduling, such as data sending or data receiving, etc. And at the end time of the timer, the timer is terminated and turned off or put into sleep. If DCI is not received within a period of time, the second module can terminate the timer in advance and turn off or put into sleep to achieve the purpose of energy saving.
[0116] Optionally, the LP-WUS may indicate whether DCI exists within a period of time. For example, the LP-WUS may carry 1-bit indication information. If the value of the 1-bit indication information is 0, it indicates that DCI exists within a period of time. If the value of the 1-bit indication information is 1, it indicates that DCI does not exist within a period of time. Conversely, if the value of the 1-bit indication information is 1, it indicates that DCI exists within a period of time. If the value of the 1-bit indication information is 0, it indicates that DCI does not exist within a period of time.
[0117] If the LP-WUS indicates that there is no DCI within a period of time, the second module can terminate the timer in advance and shut down or sleep to achieve the purpose of energy saving.
