Description

Method, network device and terminal device for wireless communication Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a method, network device, and terminal device for wireless communication. Background Art

[0002] In order to ensure the coverage of the cell and the timely availability of the network, the network equipment will always remain in a working state with high power consumption. For example, the network equipment will always remain in a working state to perform uplink reception and / or downlink transmission. For another example, the network equipment will always perform downlink transmission at the downlink transmission power corresponding to the cell coverage. However, it is not necessary for the network equipment to maintain the above-mentioned high power consumption working state in all scenarios. For example, the number of terminal devices in the cell may decrease at night (for example, some terminal devices will be turned off or enter a sleep state). At this time, if the network equipment continues to maintain the above-mentioned working state, the service provided by the network equipment will be far less than the total energy consumed by the network equipment, that is, the energy efficiency of the network equipment is low.

[0039] The technical solution in this application will be described below with reference to the accompanying drawings.

[0040] Figure 1 illustrates a wireless communication system 100 used in an embodiment of the present application. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide communication coverage for a specific geographic area and may communicate with the terminal device 120 within the coverage area.

[0041] FIG1 exemplarily shows a network device and two terminals. Optionally, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0042] Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0043] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

The terminal device in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through the base station.

[0045] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. A base station can also refer to a communication module, modem, or chip used to be provided in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form used by the network equipment.

[0046] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0047] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0048] The network equipment 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 in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0049] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0050] In existing communication systems (e.g., cellular mobile communication systems), network devices, as nodes communicating with terminal devices, can send downlink information to the terminal devices in the form of downlink signals. At the same time, the network devices can also receive uplink information sent by the terminal devices in the form of uplink signals. As shown in Figure 2, the downlink signal coverage range of the network device and the uplink signal coverage range of the terminal device together determine the size of a cell, where the cell can also be referred to as the "coverage range of the network device."

[0051] Based on current network deployment methods, to ensure real-time communication availability, network equipment must always be operational, for example, sending downlink signals to terminal devices within the cell. Alternatively, it must receive uplink signals from terminal devices within the cell. Furthermore, to maintain continuous coverage, network equipment must always transmit downlink information at the maximum downlink transmit power corresponding to the cell's coverage area.

[0052] As mentioned above, to ensure cell coverage and timely network availability, network devices will always operate at a high power consumption level. For example, network devices will always operate, performing uplink reception and / or downlink transmission. Another example is that network devices will always transmit downlink at the downlink transmit power appropriate for the cell coverage area.

[0053] However, not all scenarios require network devices to maintain this high-power operating state. For example, at night, the number of terminal devices in a cell may decrease (for example, some terminal devices may be turned off or enter a sleep state). In this case, if the network device continues to operate in this state, the services provided by the network device will be far less than the total energy consumed by the network device, that is, the network device has low energy efficiency.

[0054] Therefore, the embodiment of the present application provides a method for wireless communication, which helps improve the energy efficiency of network devices. For ease of understanding, the method for wireless communication according to the embodiment of the present application is described below in conjunction with Figure 3. The method shown in Figure 3 may include step S310.

[0055] In step S310 , if the preset condition is met, the network device adjusts the configuration of the network device, wherein the configuration of the network device includes multiple configurations corresponding to different power consumptions.

[0056] The configuration of the above network device is associated with one or more of the following information of the network device: transmission time, reception time, downlink transmission power, downlink bandwidth, and downlink modulation mode.

[0057] The correspondence between the above-mentioned multiple configurations and power consumption may include different power consumptions corresponding to different configurations in the multiple configurations, or some different configurations in the multiple configurations may correspond to the same power consumption. The correspondence between the multiple configurations and power consumption will be described below in conjunction with Table 1. For the sake of brevity, it will not be repeated here. In addition, the above-mentioned multiple configurations may be predefined or preconfigured, and this embodiment of the application is not limited to this.

[0058] The above-mentioned "if the preset condition is met, the network device adjusting the configuration of the network device" may include: if the preset condition is met, the network device adjusting the configuration of the network device to a configuration corresponding to higher power consumption among multiple configurations; or if the preset condition is met, the network device adjusting the configuration of the network device to a configuration corresponding to lower power consumption among multiple configurations. The following describes how to adjust the configuration of the network device in conjunction with specific scenarios; for the sake of brevity, the details are omitted here.

[0059] In the embodiment of the present application, when preset conditions are met, the network device can adjust its power consumption by adjusting its configuration. This avoids the situation in traditional communication systems where the network device always operates in a working state corresponding to higher energy consumption, thereby helping to improve the energy efficiency of the network device.

[0060] The following describes preset conditions applicable to embodiments of the present application. In some implementations, the preset conditions may be associated with the number of terminal devices within the coverage area of ​​the network device. For example, the preset condition may include that the number of terminal devices within the coverage area of ​​the network device is less than a first threshold. Of course, in embodiments of the present application, the preset condition associated with the number of terminal devices may also be presented in other forms. For example, the preset condition may include that the number of terminal devices is a preset value.

[0061] Taking the example of a preset condition where the number of terminal devices within the coverage area of ​​the network device is less than a first threshold, the method for adjusting the configuration of a network device in an embodiment of the present application is described. Assume that the multiple configurations include Configuration 1 and Configuration 2, where the power consumption corresponding to Configuration 1 is higher than the power consumption corresponding to Configuration 2, and the current configuration of the network device is Configuration 1. In this case, if the preset condition is met, the network device can adjust the current configuration from Configuration 1 to Configuration 2 to reduce the power consumption of the network device.

[0062] In other implementations, the preset condition may be associated with the throughput within the coverage area of ​​the network device. For example, the preset condition may include that the throughput within the coverage area of ​​the network device is less than a second threshold. Of course, in the embodiments of the present application, the preset condition associated with throughput may also be presented in other forms, for example, the preset condition may include that the throughput is a preset value.

[0063] Taking the example of a preset condition where the throughput within the coverage area of ​​the network device is less than a second threshold, the method for adjusting the configuration of a network device in an embodiment of the present application is described. Assume that the multiple configurations include Configuration 3 and Configuration 4, where the power consumption corresponding to Configuration 3 is higher than the power consumption corresponding to Configuration 4, and the current configuration of the network device is Configuration 3. In this case, if the preset condition is met, the network device can adjust the current configuration from Configuration 3 to Configuration 4 to reduce the power consumption of the network device.

[0064] It should be noted that the above-mentioned first threshold and / or second threshold can be predefined or preconfigured, and the embodiments of the present application do not limit this.

[0065] In addition, in addition to the situation where the above-mentioned preset conditions are met, the network device can adjust the configuration of the network device. The network device can also adjust the configuration of the network device based on the indication information sent by the terminal device. The following will introduce the first indication information in determination method 1 as an example. For the sake of brevity, it will not be repeated here.

[0066] As described above, the configuration of a network device can be associated with the network device's transmission time. Therefore, in embodiments of the present application, the configuration of the network device can include a first time configuration, where the first time configuration can be used to instruct the network device to perform discontinuous transmission within the downlink transmission time. The first time configuration can also be referred to as a "first transmission time configuration."

[0067] The above-mentioned discontinuous transmission can be understood as the network device performing downlink transmission at discrete transmission times. The discrete transmission times can be arranged periodically, i.e., each period includes a downlink transmission time and a time when downlink transmission is stopped. Of course, in the embodiments of the present application, the above-mentioned discrete transmission times can also be arranged aperiodically.

[0068] For ease of understanding, the following describes the discontinuous transmission of an embodiment of the present application using a periodically arranged transmission time as an example in conjunction with FIG4 . Within the three cycles shown in FIG4 , each cycle may include a transmission time and a stop transmission time. Cycle T1 includes transmission time t1 and stop transmission time s1 , cycle T2 includes transmission time t2 and stop transmission time s2 , and cycle T3 includes transmission time t3 and stop transmission time s3 . Accordingly, the network device may perform discontinuous downlink transmission at transmission time t1 , transmission time t2 , and transmission time t3 , and stop downlink transmission at stop transmission time s1 , stop transmission time s2 , and stop transmission time s3 .

[0069] In different scenarios, the discontinuous transmission indicated by the first time configuration may be expressed in slightly different ways. The following describes the FDD scenario and the TDD scenario as examples, respectively, with reference to FIG5 and FIG6.

[0070] For the FDD scenario, the first time configuration is used to instruct the network device to perform discontinuous transmission in a first downlink transmission frequency band, where the first downlink transmission frequency band is an FDD frequency band.

[0071] Referring to Figure 5 , assume that FDD frequency band 1 includes three cycles, each of which includes a transmission time and a transmission stop time. Cycle T1 includes transmission time t1 and transmission stop time s1; cycle T2 includes transmission time t2 and transmission stop time s2; and cycle T3 includes transmission time t3 and transmission stop time s3. Accordingly, the network device can perform discontinuous downlink transmissions at transmission time t1, transmission time t2, and transmission time t3, and stop downlink transmissions at transmission stop time s1, transmission stop time s2, and transmission stop time s3.

[0072] In an embodiment of the present application, the first time configuration instructs the network device to perform discontinuous transmission in the first downlink transmission frequency band supporting FDD, which helps to reduce the power consumption of the network device compared to the network device performing continuous transmission in the first downlink transmission frequency band supporting FDD.

[0073] For TDD scenarios, the first time configuration is used to indicate that the network device is in a non-transmitting state within one or more downlink time units. A downlink time unit may include a downlink time slot in a TDD frame structure. Of course, the downlink time unit may also include a downlink symbol, a downlink subframe, etc.

[0074] Referring to Figure 6, it is assumed that TDD frequency band 1 includes five downlink time units: t1 to t5, and four uplink time units r1 to r4. In addition, time configuration 1 instructs the network device to perform downlink transmission in downlink time units t1, t3, and t5, and to stop downlink transmission in downlink time units t2 and t4. Accordingly, if the instruction of time configuration 1 is not taken into account, the network device will perform downlink transmission in downlink time units t1 to t5 respectively. However, based on the instruction of time configuration 1, the network device will only perform downlink transmission in downlink time units t1, t3, and t5, and stop downlink transmission in downlink time units t2 and t4. In this way, the time interval for the network device to perform downlink transmission when time configuration 1 is not taken into account is shorter than the time interval for the network device to perform downlink transmission when time configuration 1 is taken into account. In other words, time configuration 1 adjusts the downlink transmission time of the network device to be more sparse, which helps to reduce the time for the network device to perform downlink transmission, thereby reducing the power consumption of the network device.

[0075] In an embodiment of the present application, the first time configuration is used to instruct the network device to be in a non-transmitting state in one or more downlink time units, which helps to reduce the power consumption of the network device compared to the network device being in a transmitting state in each downlink time unit.

[0076] As described above, the configuration of a network device may be associated with the reception time of the network device. Therefore, in an embodiment of the present application, the configuration of the network device may include a first time configuration, wherein the first time configuration may be used to instruct the network device to perform discontinuous reception within the uplink reception time. The first time configuration may also be referred to as a "first reception time configuration."

[0077] The above-mentioned discontinuous reception can be understood as the network device performing uplink reception at discrete reception times. The discrete reception times can be arranged periodically, i.e., each period includes an uplink reception time and a time when uplink reception is stopped. Of course, in the embodiments of the present application, the above-mentioned discrete reception times can also be arranged aperiodically.

[0078] For ease of understanding, the following describes the discontinuous reception of an embodiment of the present application using periodically arranged reception times as an example in conjunction with FIG7 . Within the three cycles shown in FIG7 , each cycle may include a reception time and a stop reception time. Cycle T1 includes a reception time r1 and a stop reception time s1 , cycle T2 includes a reception time r2 and a stop reception time s2 , and cycle T3 includes a reception time r3 and a stop reception time s3 . Accordingly, the network device may perform discontinuous uplink reception at reception time r1, reception time r2, and reception time r3, and stop uplink reception at stop reception time s1, stop reception time s2, and stop reception time s3 .

[0079] In different scenarios, the first time configuration indication of discontinuous reception may be expressed in slightly different ways. The following describes FDD and TDD as examples in conjunction with FIG8 and FIG6 respectively.

[0080] For the FDD scenario, the first time configuration is used to instruct the network device to perform discontinuous reception in a first uplink reception frequency band, where the first uplink reception frequency band is an FDD frequency band.

[0081] Assume, as shown in Figure 8, that FDD frequency band 2 includes three cycles, each of which includes a reception time and a reception stop time. Cycle T1 includes a reception time r1 and a reception stop time s1; cycle T2 includes a reception time r2 and a reception stop time s2; and cycle T3 includes a reception time r3 and a reception stop time s3. Accordingly, the network device can perform discontinuous uplink reception during reception times r1, r2, and r3, and stop uplink reception during reception stop times s1, s2, and s3.

[0082] In an embodiment of the present application, the first time configuration instructs the network device to perform discontinuous reception in the first uplink receiving frequency band supporting FDD, which helps to reduce the power consumption of the network device compared to the network device performing continuous reception in the first uplink receiving frequency band supporting FDD.

[0083] For TDD scenarios, the first time configuration is used to indicate that the network device is in a non-receiving state within one or more uplink time units. The uplink time unit may include an uplink time slot in a TDD frame structure. Of course, the uplink time unit may also include an uplink symbol, an uplink subframe, etc.

[0084] Continuing with FIG6 , it is assumed that the TDD frame structure on TDD frequency band 1 includes five downlink time units: t1 to t5, and four uplink time units r1 to r4. Furthermore, time configuration 1 instructs the network device to perform uplink reception on uplink time units r1, r3, and r5, and to stop uplink reception on uplink time units r2 and r4. Accordingly, if the instruction of time configuration 1 is not taken into account, the network device will perform uplink reception on uplink time units r1 to r4 respectively. However, based on the instruction of time configuration 1, the network device will only perform uplink reception on uplink time units r1 and r3, and stop uplink reception on uplink time units r2 and r4. In this way, the time interval for the network device to perform uplink reception without considering time configuration 1 is shorter than the time interval for the network device to perform uplink reception when considering time configuration 1. In other words, time configuration 1 adjusts the uplink reception time of the network device to be more sparse, that is, time configuration 1 adjusts the time interval for the network device to perform uplink reception to twice the time interval indicated by the TDD frame structure, which helps to reduce the time for the network device to perform uplink reception, thereby reducing the power consumption of the network device.

[0085] In an embodiment of the present application, the first time configuration is used to indicate that the network device is in a non-receiving state in one or more uplink time units, which helps to reduce the power consumption of the network device compared to the network device being in a receiving state in each uplink time unit.

[0086] It should be noted that the above describes a scheme for adjusting the downlink transmission time and uplink reception time of a network device using a first time configuration. In an embodiment of the present application, the first time configuration can also adjust both the downlink transmission time and the uplink reception time. The specific adjustment method can be similar to the adjustment method described above, and can be referred to above.

[0087] Typically, to further reduce power consumption of network devices, the discontinuous transmission and discontinuous reception described above can be used in combination. For example, for FDD, the network device's operation in the first uplink receive frequency band can be combined with the network device's operation in the first downlink transmit frequency band. For another example, for TDD, the network device can be in a non-receiving state for one or more uplink time units and in a non-transmitting state for one or more downlink time units.

[0088] For network devices, the power consumption of downlink transmission is generally much greater than that of uplink reception. Therefore, to reduce the transmission delay of uplink services, when configuring the network device to use a combination of discontinuous transmission and discontinuous reception, the duration of discontinuous reception can be shorter than the duration of discontinuous transmission. From the perspective of time configuration, the transmission duration indicated by the first transmission time configuration is shorter than the reception duration indicated by the first reception time configuration. In terms of the time domain position of the transmission time and the reception time, the transmission time indicated by the first transmission time configuration and the reception time indicated by the first reception time configuration can partially overlap.

[0089] For ease of understanding, the following describes a solution combining discontinuous transmission and discontinuous reception by taking the FDD band as an example with reference to FIG9 .

[0090] Referring to Figure 9, assume that FDD band 1 is used for downlink transmission. FDD band 1 includes three cycles, each of which may include a transmission time and a transmission stop time. Cycle T1 includes transmission time t1 and transmission stop time s1. Cycle T2 includes transmission time t2 and transmission stop time s2. Cycle T3 includes transmission time t3 and transmission stop time s3. Accordingly, the network device may perform discontinuous downlink transmission at transmission time t1, transmission time t2, and transmission time t3, and may cease downlink transmission at transmission stop time s1, transmission stop time s2, and transmission stop time s3.

[0091] FDD band 2 is used for uplink reception, wherein FDD band 2 includes 5 cycles, each of which may include a receiving time and a stop receiving time. Cycle T1' includes a receiving time r1 and a stop receiving time s1', cycle T2' includes a receiving time r2 and a stop receiving time s2', cycle T3' includes a receiving time r3 and a stop receiving time s3', cycle T4' includes a receiving time r4 and a stop receiving time s4', and cycle T5' includes a receiving time r5 and a stop receiving time s5'. Accordingly, the network device can perform discontinuous uplink reception at receiving time r1, receiving time r2, receiving time r3, receiving time r4, and receiving time r5, and stop uplink reception at stop receiving time s1', stop receiving time s2', stop receiving time s3', stop receiving time s4', and stop receiving time s5'.

[0092] Compared with the cycle of FDD band 1, the cycle of FDD band 2 is shorter. In this way, network equipment can perform uplink reception on FDD band 2 at a higher frequency to reduce the transmission delay of uplink services.

[0093] As mentioned above, for network devices, downlink transmission typically consumes significantly more power than uplink reception. Therefore, to reduce uplink service transmission latency, network devices can also perform continuous reception on the uplink receive frequency band. This is explained below using the FDD frequency band as an example, with reference to Figure 10.

[0094] Referring to Figure 10, assume that FDD band 1 is used for downlink transmission. FDD band 1 includes three cycles, each of which includes a transmission time and a transmission stop time. Cycle T1 includes transmission time t1 and transmission stop time s1; cycle T2 includes transmission time t2 and transmission stop time s2; and cycle T3 includes transmission time t3 and transmission stop time s3. Accordingly, the network device can perform discontinuous downlink transmission at transmission time t1, transmission time t2, and transmission time t3, and stop downlink transmission at transmission stop time s1, transmission stop time s2, and transmission stop time s3.

[0095] FDD Band 2 is used for uplink reception, and network devices can perform continuous uplink reception on FDD Band 2, or in other words, perform uplink reception over a continuous period of time on FDD Band 2. Compared to the periodicity of FDD Band 1, network devices can perform continuous uplink reception on FDD Band 2 to reduce the transmission latency of uplink services.

[0096] Typically, some components used for uplink reception and downlink transmission in a network device are shared. Therefore, to further conserve network device power consumption, the network device can be configured to perform uplink reception and downlink transmission at the same time, allowing these shared components to cease operation when the network device ceases operation. In other words, the transmission time indicated by the first transmission time configuration and the reception time indicated by the first reception time configuration can completely overlap.

[0097] For ease of understanding, the following describes a solution combining discontinuous transmission and discontinuous reception by taking the FDD band as an example with reference to FIG11 .

[0098] Referring to Figure 11, assume that FDD band 1 is used for downlink transmission. FDD band 1 includes three cycles, each of which may include a transmission time and a transmission stop time. Cycle T1 includes transmission time t1 and transmission stop time s1; cycle T2 includes transmission time t2 and transmission stop time s2; and cycle T3 includes transmission time t3 and transmission stop time s3. Accordingly, the network device may perform discontinuous downlink transmission at transmission time t1, transmission time t2, and transmission time t3, and may cease downlink transmission at transmission stop time s1, transmission stop time s2, and transmission stop time s3.

[0099] FDD Band 2 is used for uplink reception. FDD Band 2 includes three cycles, each of which includes a reception time and a reception stop time. Cycle T1 includes a reception time r1 and a reception stop time s1. Cycle T2 includes a reception time r2 and a reception stop time s2. Cycle T3 includes a reception time r3 and a reception stop time s3. Accordingly, the network device can perform discontinuous uplink reception during reception times r1, r2, and r3, and stop uplink reception during reception stop times s1, s2, and s3.

[0100] The cycle of FDD Band 1 is the same as the cycle of FDD Band 2. In other words, the time when the network device transmits downlink on FDD Band 1 overlaps with the time when it receives uplink on FDD Band 2. In this way, the shared components can stop working when the network device stops receiving uplink and transmitting downlink.

[0101] To increase the flexibility of the network device's uplink reception time and / or downlink transmission time, the network device may be configured with multiple time configurations. In this case, the multiple time configurations may include a first time configuration. The multiple time configurations may indicate different time periods and / or network device operating durations. The network device operating duration may, for example, be a transmission duration or a reception duration.

[0102] Taking the network device performing periodic discontinuous operation (including discontinuous transmission and / or discontinuous reception) as an example, the operation time may be the operation duration within a time period, wherein the time period may be indicated by a time configuration, or may be determined by other means.

[0103] It should be noted that the above-mentioned multiple time configurations can be predefined by the protocol or preconfigured, and the embodiments of the present application do not limit this.

[0104] The following describes various time configurations of an embodiment of the present application in conjunction with Figure 12 and Table 1. Assume that the network device can include the three time configurations shown in Table 1, wherein the transmission duration shown in Table 1 can be the transmission duration in each cycle.

[0105] Table 1

[0106] Transmission duration cycle time configuration 11ms100ms time configuration 21ms50ms time configuration 30.5ms10ms

[0107] Referring to Figure 12, the time configuration 1 shown in Table 1 can indicate that the transmission time of the network device (also called "transmission duration") is 1ms, and the transmission period is 100ms. That is to say, the network device can perform downlink transmission according to a period of 100ms, and the transmission duration in each period is 1ms. The time configuration 2 shown in Table 1 can indicate that the transmission duration of the network device is 1ms, and the transmission period is 50ms. That is to say, the network device can perform downlink transmission according to a period of 50ms, and the transmission duration in each period is 1ms. The time configuration 3 shown in Table 1 can indicate that the transmission duration of the network device is 0.1ms, and the period is 10ms. That is to say, the network device can perform downlink transmission according to a period of 10ms, and the transmission duration in each period is 0.1ms.

[0108] Comparing the three time configurations above, from a power consumption perspective, time configuration 1 indicates the longest period of the three, meaning it has the lowest power consumption. Time configuration 3 indicates the shortest period of the three, meaning it has the highest power consumption. Time configuration 2 has lower power consumption than time configuration 3, and its power consumption is higher than that of time configuration 1.

[0109] From the perspective of throughput, time configuration 1 can correspond to lower throughput. Time configuration 3 can correspond to higher throughput. The throughput corresponding to time configuration 2 is lower than that corresponding to time configuration 3, and the throughput corresponding to time configuration 2 is higher than that corresponding to time configuration 1.

[0110] It should be noted that the units of the transmission time and / or period in the above time configuration can be milliseconds as shown above, or can be units such as symbols, time slots, subframes or frames, and the embodiments of the present application are not limited to this.

[0111] In the embodiments of the present application, for network devices with multiple time configurations, determining the appropriate time configuration is an urgent problem to be solved. The embodiments of the present application provide two determination methods. In Determination Method 1, the terminal device can assist the network device in selecting the appropriate time configuration. In Determination Method 2, the network device can independently select the appropriate time configuration. The following describes each of the two determination methods.

[0112] In determination method 1, the terminal device can select a time configuration (also known as "expected time configuration") from multiple time configurations, and send the expected time configuration to the network device through a first indication message. Accordingly, the network device can determine the first time configuration based on the expected time configuration of the terminal device.

[0113] The above-mentioned multiple time configurations may be predefined by a communication protocol, or may be sent by the network device to the terminal device. For example, the network device may send them to the terminal device via broadcast or dedicated signaling (eg, RRC signaling).

[0114] In some implementations, the terminal device may select the desired time configuration based on the transmission requirements of the downlink service (e.g., transmission delay). Of course, the terminal device may also select the desired time configuration based on the throughput of the downlink service. This embodiment of the present application is not limited to this.

[0115] In other implementations, some or all terminal devices within the coverage area of ​​the network device may send their respective desired time configurations to the network device. The desired time configurations sent by different terminal devices may be different. Accordingly, the network device may determine the first time configuration based on the desired time configurations indicated by each terminal device within the coverage area.

[0116] For example, the network device can select the time configuration with the lowest power consumption among multiple desired time configurations as the first time configuration. Taking the time configurations shown in Table 1 as an example, assuming that the desired time configuration indicated by terminal device 1 is time configuration 1, the desired time configuration indicated by terminal device 2 is time configuration 2, and the desired time configuration indicated by terminal device 3 is time configuration 3, the network device can accordingly select time configuration 1 as the first time configuration from the three time configurations to reduce the power consumption of the network device.

[0117] For another example, the network device may select the time configuration with the highest power consumption among multiple desired time configurations as the first time configuration. Taking the time configurations shown in Table 1 as an example, assuming that the desired time configuration indicated by terminal device 1 is time configuration 1, the desired time configuration indicated by terminal device 2 is time configuration 2, and the desired time configuration indicated by terminal device 3 is time configuration 3, the network device may accordingly select time configuration 3 from the three time configurations as the first time configuration to reduce the transmission delay of the downlink service.

[0118] For another example, the network device may select a time configuration with medium power consumption from among multiple desired time configurations as the first time configuration. Taking the time configurations shown in Table 1 as an example, assuming that the desired time configuration indicated by terminal device 1 is time configuration 1, the desired time configuration indicated by terminal device 2 is time configuration 2, and the desired time configuration indicated by terminal device 3 is time configuration 3, the network device may select time configuration 2 as the first time configuration from the three time configurations to balance the power consumption of the network device and the transmission delay of the downlink service.

[0119] It should be noted that there are many ways to implement the scheme of the network device determining the first time configuration based on the time configuration expected by the terminal device, for example, the network device calculates the first time configuration based on the time configuration expected by the terminal device. This embodiment of the application is not limited to this.

[0120] In determination method 2, the network device may autonomously select the first time configuration from multiple time configurations.

[0121] In some implementations, the network device may select the first time configuration from multiple time configurations based on statistical information of services within the cell, where the statistical information of the services may include transmission requirements of the services (eg, transmission delay) and / or throughput of the services.

[0122] Taking the time configuration shown in Table 1 as an example, assuming that the statistical information of the service includes the throughput of the service, in this case, the selection of time configuration 1 and time configuration 2 can be determined based on throughput threshold 1, and the selection of time configuration 2 and time configuration 3 can be determined based on throughput threshold 2, where throughput threshold 2 is greater than throughput threshold 1. Accordingly, if the throughput of the current service in the cell calculated by the network device is less than or equal to throughput threshold 1, the network device can adopt time configuration 1 as the first time configuration. If the throughput of the current service in the cell calculated by the network device is less than or equal to throughput threshold 2, and the throughput of the current service is greater than throughput threshold 1, the network device can adopt time configuration 2 as the first time configuration. If the throughput of the current service in the cell calculated by the network device is greater than throughput threshold 2, the network device can adopt time configuration 3 as the first time configuration.

[0123] Taking the time configuration shown in Table 1 as an example, assuming that the statistical information of the service includes the transmission delay of the service, at this time, the selection of time configuration 1 and time configuration 2 can be determined based on the transmission delay threshold 1, and the selection of time configuration 2 and time configuration 3 can be determined based on the transmission delay threshold 2, wherein the transmission delay threshold 2 is less than the transmission delay threshold 1. Accordingly, if the network device calculates that the transmission delay of the current service in the cell is greater than the transmission delay threshold 1, the network device can adopt time configuration 1 as the first time configuration. If the network device calculates that the transmission delay of the current service in the cell is less than the transmission delay threshold 1, and the transmission delay of the current service is greater than or equal to the transmission delay threshold 2, the network device can adopt time configuration 2 as the first time configuration. If the network device calculates that the transmission delay of the current service in the cell is less than the transmission delay threshold 2, the network device can adopt time configuration 3 as the first time configuration.

[0124] It should be noted that in the embodiments of the present application, a time configuration can also be selected based on a combination of transmission latency and throughput. For example, time configuration 1 can correspond to a low throughput and low latency scenario. Time configuration 2 can correspond to a medium throughput and medium latency scenario. Time configuration 3 can correspond to a high throughput and high latency scenario.

[0125] After the network device determines the first time configuration, the network device may send the first time configuration to the terminal device, and accordingly, the terminal device may perform downlink reception or uplink transmission based on the first time configuration. For example, the terminal device may receive downlink data at the transmission time indicated by the first time configuration, and / or the terminal device may perform uplink transmission at the reception time indicated by the first time configuration.

[0126] The first time configuration can be indicated to the terminal device by the network device through broadcasting. Of course, the network device can also indicate the first time configuration to the terminal device through dedicated signaling (for example, RRC signaling). This embodiment of the present application does not limit this.

[0127] To reduce power consumption, network devices can perform discontinuous transmission. During downlink transmission cessation, downlink traffic is unreachable to the terminal device. However, in some scenarios, the terminal device needs to receive urgent traffic. In such cases, if the network device cesses downlink transmission, the network device cannot send the urgent traffic to the terminal device. For example, if the terminal device is a vehicle, the urgent traffic may include a request from the terminal device to locate an obstacle ahead to avoid a car accident. In such cases, if the network device cesses downlink transmission, the terminal device cannot determine whether there is an obstacle ahead.

[0128] Therefore, to reduce the impact of discontinuous transmission of network devices on the transmission of emergency services, the terminal device can inform the network device of the transmission time of emergency services through the second indication information. In this case, the network device can transmit the emergency services based on the second indication information. Therefore, the second indication information can also be called "emergency service indication information" or "emergency status indication information."

[0129] That is, the first time configuration includes an adjacent first transmission time and a second transmission time, and the above method also includes: the network device receives a second indication information sent by the terminal device, and the second indication information is used to instruct the network device to configure a third transmission time between the first transmission time and the second transmission time for processing emergency services.

[0130] The network device may be in a non-transmitting state for part or all of the time period between the first and second transmission times. In some implementations, the first and second transmission times may be adjacent transmission times. In this case, the network device may be in a non-transmitting state for the entire time period between the first and second transmission times. Referring to FIG5 , the first and second transmission times may be transmission time t1 and transmission time t2. Of course, the first and second transmission times may also be non-adjacent transmission times. In this case, the network device may be in a non-transmitting state for part of the time period between the first and second transmission times. Continuing with FIG5 , the first and second transmission times may be transmission time t1 and transmission time t3, respectively.

[0131] The third transmission time may include a partial or complete overlap of the transmission stop time between the first transmission time and the second transmission time. Referring to FIG5 , with transmission time t1 and transmission time t2 serving as the first transmission time and the second transmission time, the third transmission time may include a partial or complete overlap of the transmission stop time between transmission time t1 and transmission time t2. Referring to FIG5 , with transmission time t1 and transmission time t3 serving as the first transmission time and the second transmission time, the third transmission time may include a partial or complete overlap of the transmission stop time between transmission time t1 and transmission time t2, or the third transmission time may include a partial or complete overlap of the transmission stop time between transmission time t2 and transmission time t3. This will be described in detail below in conjunction with FIG13 and will not be repeated here for the sake of brevity.

[0132] It should be noted that, in the embodiment of the present application, the third transmission time may include the transmission stop time described above. Of course, the third transmission time may include the transmission stop time described above as well as the transmission time. For example, the third transmission time may include the transmission stop time between transmission time t1 and transmission time t2 in FIG. 5 , as well as part or all of the transmission time t2. This embodiment of the present application is not limited to this.

[0133] In some implementations, the second indication information includes one or more of the following information of the emergency service: start time, end time, duration, and period.

[0134] If the second indication information includes the start time of the emergency service, the start time can be determined by the time unit and the time unit offset of the second indication information. For example, if the time unit of the second indication information is the end time unit and the time unit offset is Δt, the start time of the emergency service is the start position of a time unit offset by Δt time units from the end time unit.

[0135] It should be noted that the start time in the second indication information may include a time unit offset of Δt. When the time unit offset is Δt = 0, or the second indication information does not include a time unit offset, it can be understood that the time unit offset is Δt = 0, that is, the start time of the emergency service is the end time unit of the second indication information.

[0136] In other implementations, the resources for transmitting the emergency service are determined based on preconfiguration or instructions from the network device. For example, as shown in FIG5 , the network device may indicate resources for transmitting the emergency service in period T2 at transmission time t1 of period T1.

[0137] For ease of understanding, the following describes the emergency service transmission method according to an embodiment of the present application in conjunction with FIG13 .

[0138] Referring to Figure 13, assume that FDD band 1 is used for downlink transmission. FDD band 1 includes three cycles, each of which includes a transmission time and a transmission stop time. Cycle T1 includes transmission time t1 and transmission stop time s1; cycle T2 includes transmission time t2 and transmission stop time s2; and cycle T3 includes transmission time t3 and transmission stop time s3. Accordingly, the network device can perform discontinuous downlink transmission at transmission time t1, transmission time t2, and transmission time t3, and stop downlink transmission at transmission stop time s1, transmission stop time s2, and transmission stop time s3.

[0139] Accordingly, the network device receives the second indication information sent by the terminal device in time unit 1 in cycle 1, and the second indication information indicates that the time unit offset is Δt and the duration of time unit 2 for transmitting emergency services is t e The network device can determine the starting position of time unit 2, which is the time unit after the end position of time unit 1 is offset by Δt. In addition, the network device can also determine the duration of time unit 2 as t based on the second information. e Thereafter, the network device may send the emergency service to the terminal device at time unit 2 , or in other words, the network device may send the emergency service to the terminal device within the time window of time unit 2 .

[0140] It should be noted that in the embodiment of the present application, the network device needs to receive the second indication information. Since the terminal device sends the second indication information at a relatively random time, the network device can operate in a continuous reception state to increase the possibility of receiving the second indication information. Of course, if the randomness of the second indication information is not taken into account, or the terminal device can send the second indication information according to a certain regularity, the network device can also operate in a discontinuous reception state, and the embodiment of the present application does not limit this.

[0141] In addition, the above describes the transmission solution for emergency services by taking the downlink transmission scenario as an example. The transmission solution for emergency services in the embodiment of the present application can also be applied to the uplink transmission scenario.

[0142] That is, the first time configuration includes an adjacent first receiving time and a second receiving time, and the above method also includes: the network device receives a second indication information sent by the terminal device, and the second indication information is used to indicate that the network device configures a third receiving time between the first receiving time and the second receiving time for processing emergency services.

[0143] The network device may be in a stopped-receiving state for part or all of the time period between the first and second receiving times. In some implementations, the first and second receiving times may be adjacent receiving times. In this case, the network device may be in a stopped-transmitting state for the entire time period between the first and second receiving times. Referring to FIG8 , the first and second receiving times may be receiving time r1 and receiving time r2. Of course, the first and second receiving times may also be non-adjacent receiving times. In this case, the network device may be in a stopped-transmitting state for part of the time period between the first and second receiving times. Continuing with FIG8 , the first and second receiving times may be receiving time r1 and receiving time r3, respectively.

[0144] The third receiving time may include a partial or complete overlap of the stop receiving time between the first receiving time and the second receiving time. Referring to FIG8 , with receiving time r1 and receiving time r2 serving as the first receiving time and the second receiving time, the third receiving time may include a partial or complete overlap of the stop receiving time between receiving time r1 and receiving time r2. Referring to FIG8 , with receiving time r1 and receiving time r3 serving as the first receiving time and the second receiving time, the third receiving time may include a partial or complete overlap of the stop receiving time between receiving time r1 and receiving time r2, or the third receiving time may include a partial or complete overlap of the stop receiving time between receiving time r2 and receiving time r3. This will be described in detail below in conjunction with FIG14 and will not be repeated here for the sake of brevity.

[0145] It should be noted that, in the embodiment of the present application, the third receiving time may include the stop receiving time described above. Of course, the third receiving time may include the stop receiving time described above as well as the receiving time. For example, the third receiving time may include the stop receiving time between the receiving time r1 and the receiving time r2 in FIG8 , as well as part or all of the receiving time r2. The embodiment of the present application is not limited to this.

[0146] In some implementations, the second indication information includes one or more of the following information of the emergency service: start time, end time, duration, and period.

[0147] If the second indication information includes the start time of the emergency service, the start time can be determined by the time unit and the time unit offset of the second indication information. For example, if the time unit of the second indication information is the end time unit and the time unit offset is Δt, the start time of the emergency service is the start position of a time unit offset by Δt time units from the end time unit.

[0148] It should be noted that the start time in the second indication information may include a time unit offset of Δt. When the time unit offset is Δt = 0, or the second indication information does not include a time unit offset, it can be understood that the time unit offset is Δt = 0, that is, the start time of the emergency service is the end time unit of the second indication information.

[0149] In other implementations, the resources for transmitting the emergency service are determined based on preconfiguration or instructions from the network device. For example, as shown in FIG8 , the network device may indicate resources for transmitting the emergency service in period T2 at reception time r1 of period T1.

[0150] For ease of understanding, the following describes the emergency service transmission method according to an embodiment of the present application in conjunction with FIG14 .

[0151] Referring to Figure 14 , FDD band 2 is used for uplink reception, where FDD band 2 includes three cycles, each of which may include a reception time and a reception stop time. Cycle T1′ includes a reception time r1 and a reception stop time s1′; cycle T2′ includes a reception time r2 and a reception stop time s2′; and cycle T3′ includes a reception time r3 and a reception stop time s3′. Accordingly, the network device can perform discontinuous uplink reception during reception times r1, r2, and r3, and stop uplink reception during reception stop times s1′, s2′, and s3′.

[0152] Accordingly, the network device receives the second indication information sent by the terminal device in the time unit 3 in the receiving time r1. The second indication information indicates that the time unit offset is Δt, and the duration of the time unit 4 for transmitting the emergency service is t e The network device can determine the starting position of time unit 4, which is the time unit after the end position of time unit 3 is offset by Δt. In addition, the network device can also determine the duration of time unit 4 as t based on the second information. eThereafter, the network device may receive the emergency service sent by the terminal device in the time unit 4 , or in other words, the network device may receive the emergency service sent by the terminal device within the time window indicated by the time unit 4 .

[0153] As described above, regardless of whether the network device is in a discontinuous transmission state or a discontinuous reception state, when the network device is in a non-working state (for example, a stop transmission state or a stop reception state), the network device cannot receive or send services in this state.

[0154] Therefore, in order to reduce the power consumption of network devices while reducing the impact on service transmission, an embodiment of the present application also provides a solution for wireless communication. In this solution, the network device can perform discontinuous operation (e.g., discontinuous reception and / or discontinuous transmission) on a first bandwidth and perform continuous operation on a second bandwidth. In this way, the continuous operation of the network device on the second bandwidth can support the transmission of services, helping to reduce the transmission delay of services. In addition, the discontinuous operation of the network device on the first bandwidth helps to reduce the power consumption of the network device.

[0155] That is, the first time configuration corresponds to the first bandwidth of the network device, and the network device also includes a second bandwidth, the second bandwidth corresponds to the second time configuration, and the second time configuration is used to indicate one or more of the following: the network device continuously transmits within the downlink transmission time; the network device continuously receives within the uplink reception time.

[0156] The above-mentioned network device may perform continuous transmission within the downlink transmission time in various situations, which are described below using the TDD frequency band and the FDD frequency band as examples.

[0157] For the FDD frequency band, the network device performs continuous transmission within the downlink transmission time, which can be understood as the network device performing continuous downlink transmission within the FDD downlink transmission frequency band.

[0158] For the TDD frequency band, the network device continuously transmits within the downlink transmission time, which can be understood as the network device performing downlink transmission within the continuous downlink transmission time indicated by the TDD frame structure, wherein the continuous downlink transmission time indicated by the TDD frame structure can be a transmission time unit with continuous indexes but discontinuous time domain positions. Referring to Figure 6, taking the TDD frame structure shown in TDD frequency band 1 as the TDD frame structure of the second bandwidth as an example, the network device continuously transmits within the downlink transmission time, which can be understood as the network device performing downlink transmission at transmission times t1 to t5.

[0159] The above-mentioned network device may perform continuous reception within the uplink reception time in various situations, which are described below using the TDD frequency band and the FDD frequency band as examples.

[0160] For the FDD frequency band, the network device continuously transmits within the uplink reception time, which can be understood as the network device continuously performing uplink reception within the FDD uplink reception frequency band.

[0161] For the TDD frequency band, the network device continuously transmits within the uplink reception time, which can be understood as the network device performing uplink reception within the continuous uplink reception time indicated by the TDD frame structure, wherein the continuous uplink reception time indicated by the TDD frame structure can be a reception time unit with continuous indexes but discontinuous time domain positions. Referring to Figure 6, taking the TDD frame structure shown in TDD frequency band 1 as the TDD frame structure of the second bandwidth as an example, the network device continuously receives within the uplink reception time, which can be understood as the network device performing downlink transmission at reception times r1 to r4.

[0162] In some implementations, the first bandwidth may be greater than the second bandwidth, that is, the bandwidth of the network device in continuous operation is smaller than the bandwidth of the network device in discontinuous operation, which helps to reduce the power consumption of the network device.

[0163] In some implementations, the network device may include one or more bandwidths for discontinuous operation. Specifically, the first bandwidth may include one or more bandwidths. When the first bandwidth includes multiple bandwidths, the first time configuration includes a first transmission time and a second transmission time, where the first transmission time and the second transmission time correspond to different bandwidths in the multiple bandwidths. This allows the network device to perform discontinuous operation on multiple bandwidths with different transmission times, thereby increasing the flexibility of the network device in providing services for service transmission.

[0164] In some implementations, to reduce the power consumption of network devices, the network device may first operate continuously on the second bandwidth, and then determine whether to operate discontinuously on the first bandwidth based on the service transmission requirements within the cell and / or the number of terminal devices within the cell. The service transmission requirements within the cell may include the cell throughput and the transmission delay of the service within the cell. For example, when the throughput of the service within the cell is greater than a throughput threshold, the network device may activate the first bandwidth. For another example, when the number of terminal devices within the cell is greater than a terminal device number threshold, the network device may activate the first bandwidth.

[0165] In other implementations, after the first bandwidth is activated, the network device may also determine whether it is necessary to stop performing discontinuous work on the first bandwidth based on the service transmission demand within the cell and / or the number of terminal devices within the cell. In other words, the network device may also determine whether it is necessary to deactivate the first bandwidth based on the service transmission demand within the cell and / or the number of terminal devices within the cell. For example, when the throughput of the service within the cell is less than or equal to the throughput threshold, the network device may deactivate the first bandwidth. For another example, when the number of terminal devices within the cell is less than or equal to the terminal device number threshold, the network device may deactivate the first bandwidth.

[0166] In some scenarios, there may be specific areas within a cell with higher service transmission latency requirements and / or higher throughput. Therefore, in some implementations, the first bandwidth may also be the bandwidth for certain areas within the cell. In other embodiments, the second bandwidth may be the bandwidth for all areas within the cell. In other words, the first bandwidth corresponds to the entire coverage area of ​​the network device, and the second bandwidth corresponds to a portion of the coverage area of ​​the network device.

[0167] For ease of understanding, the following describes the coverage areas corresponding to different bandwidths in an embodiment of the present application in conjunction with FIG15 . Referring to FIG15 , taking the first bandwidth as downlink transmission bandwidth BW0 as an example, BW0 may correspond to the entire coverage area 1510 of the network device. Taking the second bandwidth as downlink transmission bandwidth BW1 as an example, BW1 may correspond to area 1520 within the entire coverage area 1510 of the network device.

[0168] In other scenarios, there may be some specific terminal devices in the cell that have higher service transmission delay requirements, and / or the throughput of specific terminal devices is larger. Therefore, in some implementations, the above-mentioned first bandwidth may also be the bandwidth for certain terminal devices in the cell. In other embodiments, the second bandwidth may be the bandwidth for all terminal devices in the cell. In other words, the first bandwidth corresponds to all terminal devices within the coverage of the network device, and the second bandwidth corresponds to some terminal devices within the coverage of the network device. In other words, the first bandwidth may be a special configuration for certain terminal devices in the cell, and correspondingly, the second bandwidth may be a general configuration for all terminal devices in the cell.

[0169] For ease of understanding, the following text describes the communication method based on the first bandwidth and the second bandwidth in an embodiment of the present application, taking the FDD frequency band as an example with reference to FIG. 16 and FIG. 17 .

[0170] Referring to Figure 16 , assume that the downlink transmission bandwidth of a network device includes BW0 to BW3. BW0 has the smallest bandwidth and can correspond to the entire coverage area of ​​the network device. BW1 to BW3 can correspond to portions of the network device's coverage area. Furthermore, BW1 has a larger bandwidth than BW2, and BW2 has a larger bandwidth than BW3.

[0171] Accordingly, if the network device detects that the cell throughput is greater than throughput threshold 1 and less than throughput threshold 2 at the start of time period t1, the network device can activate downlink transmission bandwidth BW1 and perform downlink transmission on BW1 to cope with the higher throughput. If the network device detects that the cell throughput is less than or equal to throughput threshold 1 at the end of time period t1, the network device can deactivate downlink transmission bandwidth BW1 to reduce power consumption.

[0172] If, at the start of time period t2, the network device detects that the cell throughput is greater than or equal to throughput threshold 2, and that the cell throughput is less than throughput threshold 3, the network device may activate downlink transmission bandwidth BW2 and perform downlink transmissions at BW2 to accommodate the higher throughput. If, at the end of time period t2, the network device detects that the cell throughput is less than or equal to throughput threshold 2, the network device may deactivate downlink transmission bandwidth BW2 to reduce power consumption.

[0173] If the network device detects that the cell throughput is greater than or equal to throughput threshold 3 at the start of time period t3, the network device can activate downlink transmission bandwidth BW3 and perform downlink transmission at BW3 to accommodate the higher throughput. If the network device detects that the cell throughput is less than or equal to throughput threshold 3 at the end of time period t3, the network device can deactivate downlink transmission bandwidth BW3 to reduce power consumption. Where throughput threshold 1 is less than throughput threshold 2, and throughput threshold 2 is less than throughput threshold 3.

[0174] In the embodiment of the present application, since the bandwidth of BW0 is small, the throughput that can be handled within the cell is relatively limited. Therefore, one or more of BW1 to BW3 can be activated or deactivated based on the monitored throughput within the cell, which helps to reduce the power consumption of network equipment while taking into account the transmission needs of the business.

[0175] Referring to Figure 17 , assume that the network device's uplink receive bandwidths range from BW4 to BW7. BW4 has the smallest bandwidth and can cover the entire coverage area of ​​the network device. BW5 to BW7 can cover portions of the network device's coverage area. Furthermore, BW5 has a greater bandwidth than BW6, and BW6 has a greater bandwidth than BW7.

[0176] Accordingly, if the network device detects that the throughput within the cell is greater than throughput threshold 4 at the start of time period t4, and that the throughput within the cell is less than throughput threshold 5, the network device can activate uplink receive bandwidth BW5 and perform uplink reception at BW5 to cope with the higher throughput. If the network device detects that the throughput within the cell is less than or equal to throughput threshold 4 at the end of time period t4, the network device can deactivate uplink receive bandwidth BW5 to reduce power consumption of the network device.

[0177] If the network device detects that the cell throughput is greater than or equal to throughput threshold 5 at the start of time period t5, and that the cell throughput is less than throughput threshold 6, the network device can activate uplink receive bandwidth BW6 and perform uplink reception at BW6 to accommodate the higher throughput. If the network device detects that the cell throughput is less than or equal to throughput threshold 5 at the end of time period t5, the network device can deactivate uplink receive bandwidth BW6 to reduce power consumption.

[0178] If the network device detects that the cell throughput is greater than or equal to throughput threshold 6 at the start of time period t6, the network device can activate uplink receive bandwidth BW7 and perform uplink reception at BW7 to accommodate the higher throughput. If the network device detects that the cell throughput is less than or equal to throughput threshold 6 at the end of time period t6, the network device can deactivate uplink receive bandwidth BW7 to reduce power consumption. Where throughput threshold 4 is less than throughput threshold 5, and throughput threshold 5 is less than throughput threshold 6.

[0179] In the embodiment of the present application, since the bandwidth of BW4 is small, the throughput that can be handled within the cell is relatively limited. Therefore, one or more of BW5 to BW7 can be activated or deactivated based on the monitored throughput within the cell, which helps to reduce the power consumption of network equipment while taking into account the transmission needs of the business.

[0180] The following text combines Figures 18 and 19 to take the TDD frequency band as an example to introduce the communication method based on the first bandwidth and the second bandwidth in an embodiment of the present application.

[0181] Referring to Figure 18, it is assumed that TDD frequency band 1 includes 5 downlink time units: t1 to t5, and 4 uplink time units r1 to r4. In addition, time configuration 1 instructs the network device to perform downlink transmission in downlink time units t1, t3, and t5, and to stop downlink transmission in downlink time units t2 and t4. In addition, the downlink transmission bandwidth of the network device includes BW0 to BW3. Among them, BW0 has the smallest bandwidth, and BW0 can correspond to the entire coverage range of the network device. BW1 to BW3 can correspond to partial areas within the coverage range of the network device. In addition, the bandwidth of BW1 is greater than BW2, and the bandwidth of BW2 is greater than BW3.

[0182] Accordingly, if the network device detects that the throughput within the cell is greater than throughput threshold 1 and less than throughput threshold 2 at the start of time unit t1, the network device can activate downlink transmission bandwidth BW1 and perform downlink transmission on BW1 to cope with the higher throughput. If the network device detects that the throughput within the cell is less than or equal to throughput threshold 1 at the end of time unit t1, the network device can deactivate downlink transmission bandwidth BW1 to reduce power consumption of the network device.

[0183] If, at the start of time unit t3, the network device detects that the throughput within the cell is greater than or equal to throughput threshold 2, and that the throughput within the cell is less than throughput threshold 3, the network device may activate downlink transmission bandwidth BW2 and perform downlink transmission on BW2 to accommodate the higher throughput. If, at the end of time unit t3, the network device detects that the throughput within the cell is less than or equal to throughput threshold 2, the network device may deactivate downlink transmission bandwidth BW2 to reduce power consumption.

[0184] If the network device detects that the cell throughput is greater than or equal to throughput threshold 3 at the start of time unit t5, the network device can activate downlink transmission bandwidth BW3 and perform downlink transmission at BW3 to accommodate the higher throughput. If the network device detects that the cell throughput is less than or equal to throughput threshold 3 at the end of time unit t5, the network device can deactivate downlink transmission bandwidth BW3 to reduce power consumption. Where throughput threshold 1 is less than throughput threshold 2, and throughput threshold 2 is less than throughput threshold 3.

[0185] In the embodiment of the present application, since the bandwidth of BW0 is small, the throughput that can be handled within the cell is relatively limited. Therefore, one or more of BW1 to BW3 can be activated or deactivated based on the monitored throughput within the cell, which helps to reduce the power consumption of network equipment while taking into account the transmission needs of the business.

[0186] Referring to Figure 19, it is assumed that TDD frequency band 1 includes 5 downlink time units: t1 to t5, and 4 uplink time units r1 to r4. In addition, time configuration 1 instructs the network device to perform uplink reception in uplink time units r1 and r3, and stop uplink reception in uplink time units r2 and r4. In addition, the uplink reception bandwidth of the network device includes BW0 to BW2. Among them, BW0 has the smallest bandwidth, and BW0 can correspond to the entire coverage range of the network device. BW1 to BW2 can correspond to partial areas within the coverage range of the network device. And the bandwidth of BW1 is greater than BW2.

[0187] Accordingly, if the network device detects that the throughput within the cell is greater than throughput threshold 1 and less than throughput threshold 2 at the start of time unit r1, the network device can activate uplink receive bandwidth BW1 and perform uplink reception at BW1 to cope with the higher throughput. If the network device detects that the throughput within the cell is less than or equal to throughput threshold 1 at the end of time unit r1, the network device can deactivate uplink receive bandwidth BW1 to reduce power consumption.

[0188] If the network device detects that the cell throughput is greater than or equal to throughput threshold 2 at the start of time unit r3, the network device can activate uplink receive bandwidth BW2 and perform uplink reception at BW2 to accommodate the higher throughput. If the network device detects that the cell throughput is less than or equal to throughput threshold 2 at the end of time unit r3, the network device can deactivate uplink receive bandwidth BW2 to reduce power consumption. Where throughput threshold 1 is less than throughput threshold 2.

[0189] In the embodiment of the present application, since the bandwidth of BW0 is small, the throughput that can be handled within the cell is relatively limited. Therefore, one or more of BW1 to BW2 can be activated or deactivated based on the monitored throughput within the cell, which helps to reduce the power consumption of network equipment while taking into account the transmission needs of the business.

[0190] In embodiments of the present application, the first and second bandwidths can be configured in a variety of ways. In some implementations, the first and second bandwidths can correspond to independent bandwidth configurations. In other words, the network device can activate the first and second bandwidths separately. Referring to Figure 16 , if BW0 and BW1 use independent bandwidth configurations, the network device can activate BW1 during time unit t1.

[0191] In other implementations, the first and second bandwidths may correspond to non-independent bandwidth configurations. That is, at a given moment, the network device activates a bandwidth combination that includes the first and second bandwidths. Referring to Figure 16 , if BW0 and BW1 use non-independent bandwidth configurations, then, during time unit t1, the network device may activate a band combination that includes BW0 and BW1.

[0192] In some implementations, the size of the second bandwidth and / or the duration of the second bandwidth are configurable. For example, the network device can configure the size of the second bandwidth and / or the duration of the second bandwidth based on statistical information of the cell. The statistical information of the cell includes the number of terminal devices in the cell, the cell throughput, the transmission requirements of services within the cell, etc. Of course, in the embodiments of the present application, the size of the second bandwidth can also be selected from multiple predefined bandwidths, and the duration of the second bandwidth can also be selected from multiple predefined durations.

[0193] In other implementations, the second bandwidth may be configured periodically, and accordingly, the network device may inform terminal devices within the cell of the configuration period of the second bandwidth. For example, this may be done through a broadcast message, RRC signaling, or other similar message. Of course, the second bandwidth may also be configured aperiodically, and accordingly, the network device dynamically schedules the activation time of the second bandwidth for the terminal devices.

[0194] As is well known, reducing the transmit power of network devices can reduce their power consumption. However, the transmit power of network devices has a significant impact on the downlink coverage of a cell. Generally, reducing the transmit power of network devices will directly reduce the downlink coverage of a cell. As shown in Figure 20, assuming that the network device performs downlink transmission at transmit power 1, the coverage of the network device is 2010. When the transmit power of the network device is reduced from transmit power 1 to transmit power 2, the coverage of the network device may be reduced from coverage 2010 to coverage 2020. This reduction in coverage may result in discontinuous network coverage. When a terminal device is located in an area within coverage 2010 other than coverage 2020, the network device cannot communicate with the terminal device, causing the terminal device to be in an out-of-service state.

[0195] Therefore, in order to reduce the impact of reducing the transmission power of network equipment on the coverage range, in an embodiment of the present application, the transmission power has a matching configuration parameter, or in other words, the transmission power can correspond to a configuration parameter, which is used to indicate the configurable downlink bandwidth and / or downlink modulation mode of the network device.

[0196] The above-mentioned transmission power can be the transmission power corresponding to the coverage range of the network device, and the above-mentioned transmission power can also be the maximum transmission power of the network device. The embodiments of the present application do not limit this.

[0197] The configurable downlink bandwidth may be, for example, the maximum configurable downlink bandwidth. Of course, the configurable downlink bandwidth may also be a certain configurable downlink bandwidth, which is not limited in the embodiment of the present application.

[0198] The configurable downlink modulation mode may be, for example, the most complex configurable downlink modulation mode. Of course, the configurable downlink modulation mode may also be a configurable downlink modulation mode, which is not limited in the embodiment of the present application.

[0199] In some implementations, the downlink modulation methods may include 16-quadrature amplitude modulation (16QAM), quadrature reference phase shift keying (QPSK), staggered quadrature phase shift keying, quadrature relative phase shift keying, Gaussian filtered minimum shift keying (GMSK), minimum shift keying (MSK), etc.

[0200] In some implementations, if the configuration of the network device can be associated with the downlink transmit power of the network device, then the configuration of the network device includes one or more downlink transmit power configurations, and the downlink transmit power configuration is used to indicate the mapping relationship between the downlink transmit power of the network device and the configuration parameters.

[0201] It should be noted that the embodiments of the present application do not limit the mapping relationship between the downlink transmit power and the configuration parameters of the network device. For example, the mapping relationship between the downlink transmit power and the configuration parameters can be a one-to-one mapping relationship. For another example, the mapping relationship between the downlink transmit power and the configuration parameters can be a one-to-many mapping relationship.

[0202] Taking the configuration parameters including downlink bandwidth as an example, when for lower transmission power, less bandwidth can be matched, so that the transmission power can be concentrated on smaller frequency domain resources. Correspondingly, when for higher transmission power, a larger bandwidth can be matched. This helps to make the power density transmitted on unit frequency domain resources similar or the same when using different transmission powers. This helps to achieve the same coverage range of network equipment when using different transmission powers.

[0203] That is to say, the above-mentioned downlink transmit power configuration includes a first downlink transmit power configuration and a second downlink transmit power configuration, the first downlink power configuration is used to indicate a mapping relationship between the first downlink transmit power and the first configuration parameter, the second downlink transmit power configuration is used to indicate a mapping relationship between the second downlink transmit power and the second configuration parameter, the first downlink transmit power is less than the second downlink transmit power, and the downlink bandwidth indicated by the first configuration parameter is less than the downlink bandwidth indicated by the second configuration parameter.

[0204] For example, if the downlink modulation scheme is configured with low complexity, the terminal device's demodulation threshold for receiving signals is low. In this case, the terminal device can typically successfully demodulate signals with low signal strength. If the downlink modulation scheme is complex, the terminal device's demodulation threshold for receiving signals is high. In this case, the terminal device must typically successfully demodulate signals with high signal strength.

[0205] Thus, to help network devices achieve the same or similar coverage when operating at different transmit powers, a higher transmit power can be associated with a more complex downlink modulation scheme, and a lower transmit power can be associated with a simpler downlink modulation scheme. In other words, the complexity of the downlink modulation scheme indicated by the first configuration parameter is less than the complexity of the downlink modulation scheme indicated by the second configuration parameter.

[0206] For ease of understanding, the following describes the downlink transmit power configuration in the embodiment of the present application in conjunction with Table 2.

[0207] Table 2

[0208]

[0209] As shown in Table 2, in downlink transmit power configuration 1, when the maximum transmit power of the network device is 30dBm, the maximum configurable downlink bandwidth of the network device is 200MHz, and the most complex configurable downlink modulation mode of the network device is 16QAM. In downlink transmit power configuration 2, when the maximum transmit power of the network device is 27dBm, the maximum configurable downlink bandwidth of the network device is 100MHz, and the most complex configurable downlink modulation mode of the network device is 16QAM. In downlink transmit power configuration 3, when the maximum transmit power of the network device is 27dBm, the maximum configurable downlink bandwidth of the network device is 200MHz, and the most complex configurable downlink modulation mode of the network device is QPSK. In downlink transmit power configuration 4, when the maximum transmit power of the network device is 10dBm, the maximum configurable downlink bandwidth of the network device is 50MHz, and the most complex configurable downlink modulation mode of the network device is QPSK.

[0210] It should be noted that if the configuration parameters include the maximum configurable downlink bandwidth and the most complex configurable downlink modulation mode, only one of the above two parameters can be adjusted. For example, referring to the downlink transmission power configuration shown in the first and second rows of Table 2, when the maximum transmission power of the network device is adjusted from 30dBM to 27dBm, only the maximum configurable downlink bandwidth of the network device can be adjusted, and the most complex configurable downlink modulation mode remains unchanged. For another example, referring to the downlink transmission power configuration shown in the first and third rows of Table 2, when the maximum transmission power of the network device is adjusted from 30dBM to 27dBm, only the most complex configurable downlink modulation mode of the network device can be adjusted, and the maximum configurable downlink bandwidth remains unchanged. This mapping method helps to keep the coverage of the network device the same or similar when the network device operates at different transmission powers.

[0211] For ease of understanding, the following describes a method for adjusting the downlink transmit power configuration of a network device, taking the downlink transmit power configuration shown in Table 2 as an example, in combination with the preset conditions described above.

[0212] Taking the preset condition including the number of terminal devices within the coverage range of the network device being less than a first threshold as an example, referring to Table 2, assuming that the network device operates based on downlink transmit power configuration 1, when the network device detects that the number of terminal devices within the coverage range is less than the first threshold, the network device may switch from downlink transmit power configuration 1 to downlink transmit power configuration 2 and operate based on downlink transmit power configuration 2 to reduce the power consumption of the network device. Subsequently, when the network device detects that the number of terminal devices within the coverage range is greater than or equal to the first threshold, the network device may switch from downlink transmit power configuration 2 back to downlink transmit power configuration 1 and operate based on the parameters indicated by downlink transmit power configuration 1 to reduce the delay of service transmission.

[0213] It should be noted that, based on the above description, downlink transmit power configuration 1 and downlink transmit power configuration 2 can correspond to the same threshold value (first threshold value). Of course, in the embodiment of the present application, different downlink transmit power configurations can correspond to different threshold values, and the embodiment of the present application does not limit this.

[0214] Taking the preset condition that the throughput within the coverage area of ​​the network device is less than the second threshold as an example, referring to Table 2, assuming that the network device operates based on downlink transmit power configuration 1, when the network device detects that the throughput within the coverage area is less than the second threshold, the network device may switch from downlink transmit power configuration 1 to downlink transmit power configuration 3 and operate based on downlink transmit power configuration 3 to reduce the power consumption of the network device. Subsequently, when the network device detects that the throughput within the coverage area is greater than or equal to the second threshold, the network device may switch from downlink transmit power configuration 3 back to downlink transmit power configuration 1 and operate based on the parameters indicated by downlink transmit power configuration 1 to reduce the delay of service transmission.

[0215] It should be noted that, based on the above description, downlink transmit power configuration 1 and downlink transmit power configuration 3 can correspond to the same threshold value (second threshold value). Of course, in the embodiment of the present application, different downlink transmit power configurations can correspond to different threshold values, and the embodiment of the present application does not limit this.
