Description

Method and apparatus for transmitting uplink signal

[0001] The present application claims priority to the Chinese patent application No. 202411034378.3, filed on July 29, 2024, and entitled "Method and apparatus for transmitting uplink signal", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

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

[0003] When both the terminal device and the network device support super uplink, the network device can configure a super uplink working mode for the terminal device. The super uplink working mode means that the terminal device can perform uplink transmission on two carriers, and the two carriers are multiplexed by time division, which is beneficial to fully utilize uplink resources and improve uplink coverage and throughput.

[0004] In the super uplink working mode, in order to adapt to the dynamic change of the quality of service of the terminal device, the network device can instruct the terminal device to frequently report signals related to channel detection, such as sounding reference signal (SRS) and channel state information (CSI), when the network device resources allow, so that the network device can detect the channel quality in real time.

[0005] However, in this way, the power consumption of the terminal device is high. SUMMARY

[0006] The present application provides a method and apparatus for transmitting uplink signal, which is beneficial to reduce the power consumption of the terminal device.

[0007] In a first aspect, a method for transmitting uplink signal is provided, which can be applied to a terminal device. The method can include: receiving first indication information, the first indication information being used to indicate that a transmission period of the uplink signal includes a first period; and transmitting the uplink signal in a case where a first condition is met, the transmission period of the uplink signal being a second period, the length of the second period being greater than the length of the first period, and the first condition being related to the power consumption and / or service of the terminal device.

[0008] The method for transmitting uplink signal provided by the present application can be used by the terminal device to transmit the uplink signal in the second period with a longer length than the first period in the case where the first condition is met, instead of using the first period indicated by the network device. This is beneficial to meet the needs of the service and reduce the power consumption of the terminal device.

[0009] In a possible implementation, before the uplink signal is sent when the first condition is met, the method further includes: receiving a second condition, the priority of the second condition being higher than the priority of the first condition, the second condition being related to uplink and downlink traffic and / or service; and sending the uplink signal when the second condition is met; or, when the first condition is met, sending the uplink signal includes: sending the uplink signal when the second condition is not met and the first condition is met.

[0010] If the second condition is met, the uplink signal does not need to be frequently sent, and the terminal device can send the uplink signal using the second period. If the second condition is not met but the first condition is met, it indicates that the uplink signal does not need to be frequently sent, and the terminal device can send the uplink signal using the second period.

[0011] In this way, it is beneficial to reduce power consumption of the terminal device while meeting the service.

[0012] In a possible implementation, the method further includes: receiving second indication information, the second indication information being used to indicate that discontinuous reception of the uplink signal is supported; and sending the uplink signal when the first condition is met includes: based on the second indication information, sending the uplink signal when the first condition is met.

[0013] The method for transmitting the uplink signal provided in this application can be used by the terminal device to send the uplink signal to the network device without using the indicated first period when the network device can support discontinuous reception of the uplink signal. In this way, when the network device does not receive the uplink signal within the specified period, it will not consider that the terminal device transmits the signal abnormally or that the channel environment deteriorates, and thus will not perform reconfiguration, which is beneficial to system stability.

[0015] The terminal device can send the uplink signal on the carrier or the frequency band indicated by the network device, which is more flexible.

[0016] In a possible implementation, the length of the second period is less than or equal to the length of the third period. In this way, the length of the second period is not infinite, which is beneficial to improve data transmission efficiency.

[0018] In this way, the terminal device can negotiate with the network device to use a long period to transmit the uplink signal, which is beneficial to reduce power consumption of the terminal device.

[0020] In this way, the terminal device can negotiate with the network device to use a short period to transmit the uplink signal, which is beneficial to improve performance of the terminal device.

[0021] In a possible implementation, before the transmitting the uplink signal, the method further comprises: transmitting fifth indication information, the fifth indication information being used to indicate that the uplink signal is transmitted by using the second period.

[0022] In this way, the terminal device reports to the network device when starting to use a longer period, and informs the network device to use the longer period. After receiving the indication, the network device can start discontinuous detection, which is beneficial to reduce detection load of the network device.

[0023] In a possible implementation, the method further comprises: transmitting indication information used to indicate that the uplink signal is stopped from being transmitted by using the second period.

[0024] In this way, the terminal device reports to the network device when stopping to use a longer period, and informs the network device to stop using the longer period. After receiving the indication, the network device can start continuous detection, which is beneficial to improve reception efficiency of the uplink signal.

[0025] In a second aspect, a transmission method of an uplink signal is provided, which can be applied to a network device.

[0026] In a possible implementation, the second condition is sent before the uplink signal is received, and the second condition is related to uplink and downlink traffic and / or service.

[0027] In a possible implementation, the second indication information is sent before the uplink signal is received, and the second indication information is used to indicate that the discontinuous reception uplink signal is supported.

[0028] In a possible implementation, the first indication information is also used to indicate a target carrier or a target frequency band; and the uplink signal is sent under the condition that the first condition is met, including: the uplink signal is sent on the target carrier or the target frequency band under the condition that the first condition is met.

[0029] In a possible implementation, the length of the second period is less than or equal to the length of the third period.

[0071] In order to better understand the embodiments of the present application, first, the terms and prior art involved in the embodiments of the present application are introduced.

[0072] 1. 4G network capability and 5G network capability

[0073] In the 4G era, the demand of users for the network is mainly concentrated in online movie watching or video downloading, and the demand for the network is high downlink rate. Therefore, the 4G network capability is mainly to ensure the downlink service rate.

[0074] With the continuous development of mobile communication networks, people's demand for networks is constantly improving, which has given birth to faster, higher and stronger 5G networks. In the 5G era, with the emergence of new services such as self-media, AR, VR, Cloud VR, autonomous driving, unmanned inspection machines, unmanned mining machines, 4K live broadcast, and the like, the demand of users for the network has changed. In addition to the requirement of high rate for downlink service, higher requirements for uplink service rate are put forward. Therefore, the 5G network capability needs to ensure the uplink service rate and the downlink service rate.

[0075] Therefore, compared with the 4G network, the 5G network needs a network that can provide large uplink and downlink bandwidth.

[0076] 2. TDD and FDD

[0077] In the 5G network, there are multiple duplex modes, and the embodiments of the present application mainly introduce two duplex modes, TDD and FDD.

[0078] FDD: uplink and downlink services are transmitted on two independent, symmetric frequency bands.

[0079] TDD: uplink and downlink services are transmitted on different time slots of one frequency band.

[0080] For example, Table 1 shows a case of FDD and TDD low frequency band definition.

[0081] Table 1

[0082] As can be seen from Table 1, the uplink and downlink services of FDD are transmitted on two independent, symmetric frequency bands. The uplink and downlink services of TDD are transmitted on different time slots of one frequency band.

[0083] In the 5G network, the maximum available bandwidth range of TDD can be up to 900 mega hertz (MHz), which is much larger than the available bandwidth range of FDD. For services that need to be implemented with large bandwidth, a cell is generally deployed in TDD.

[0084] In the TDD cell, the ratio of uplink and downlink services is determined by the time slot ratio. According to different service requirements, the operator can choose different time slot ratios. Common time slot ratios can include: 8:2, 7:3, 4:1.

[0085] For example, FIG. 1 shows a schematic diagram of a time slot ratio. As shown in FIG. 1, D is used to represent a downlink time slot, U is used to represent an uplink time slot, and S is used to represent a flexible time slot, which can be a downlink time slot or an uplink time slot. The uplink and downlink services are transmitted on different time slots of one frequency band, which is a TDD mode. The S time slot is understood as a downlink time slot in the time slot configuration.

[0086] As can be seen from FIG. 1, 8 time slots of 10 time slots are used for downlink service transmission, and 2 time slots are used for uplink service transmission. Therefore, in the TDD cell, the time slot ratio is 8:2. The terminal device can receive downlink signals through 8 time slots and send uplink signals through 2 time slots. As can be seen from the time slot ratio, the time slots used for uplink service transmission are much less than the time slots used for downlink service transmission.

[0087] When the time slots used for uplink service transmission are much less than the time slots used for downlink service transmission in the time slot ratio, the uplink bandwidth will be limited.

[0088] 3, Coverage capability of 5G network

[0089] In the defined sub6G frequency band, most of the frequency bands below 3 gigahertz (GHz) have been allocated to mobile communication networks before 5G or other systems, so the 5G network mainly uses medium and high frequency bands.

[0090] 5G uses higher frequency spectrum to obtain more bandwidth resources, but the propagation characteristics of wireless signals are that the higher the frequency, the greater the spatial loss in space propagation, which will affect the coverage capability of the 5G network. According to the propagation model, at the same distance: 3.5GHz is about 5.8 decibels (dB) higher than 1.8GHz in path loss; 3.5GHz is about 4.4dB higher than 2.1GHz in path loss.

[0091] Although advanced technologies such as massive multiple input multiple output (MIMO) are introduced in the 5G network, which can partially reduce the difference in propagation loss with the low frequency band, the coverage capability of the medium and high frequency band is still weaker than that of the traditional low frequency band.

[0092] Exemplarily, Table 2 shows the loss of signals of different frequency bands in different propagation media according to an embodiment of the present application.

[0093] Table 2

[0094] As shown in Table 2, for the same propagation medium, the higher the frequency band, the greater the loss. This can explain that the coverage capability of the medium and high frequency band is weaker than that of the low frequency band.

[0095] 4, Supplementary up link (SUL)

[0096] In order to compensate for the loss of terminal device in far-end uplink transmission in air interface propagation, for example, the above-mentioned limited uplink bandwidth and the weaker coverage capability of the medium and high frequency band, in the standard protocol of release (R) 15, SUL is defined to improve the cell coverage range and improve the uplink data volume. As can be seen from Table 1, SUL is only used for uplink transmission, not for downlink transmission.

[0097] The terminal device can switch between the SUL defined in R15 and the uplink of TDD itself (also known as NUL). That is, in the uplink time slot of NUL, the terminal device can use NUL to transmit uplink data; in the downlink time slot of NUL, the terminal device can use SUL link to transmit uplink data.

[0098] In this implementation, the SUL will fixedly preempt the transmission resource of one transmitting antenna (1Tx), and the NUL also needs to fallback to 1Tx transmission, so the fallback of the NUL will cause the MIMO capability of the NUL to be not released when near the point, that is, the MIMO capability is not fully utilized.

[0099] For example, FIG. 2 shows a schematic diagram of NUL 1Tx and SUL 1Tx uplink combination. As shown in FIG. 2, D is used to represent a downlink time slot, U is used to represent an uplink time slot, and G is used to represent a switching time slot for uplink and downlink switching. The frequency of the NUL can be 100 MHz, and the frequency of the SUL can be 20 MHz. In the uplink time slot of the NUL, the terminal device can transmit uplink data by using NUL 1Tx. In the downlink time slot of the NUL, the terminal device can transmit uplink data by using SUL 1Tx link.

[0100] 5. Super uplink

[0101] In the standard protocol of R16, a super uplink is defined, which can solve the above-mentioned problem in R15. The super uplink is an additional uplink in a TDD cell. In this way, the uplink is expanded by time division scheduling of NUL and SUL without changing the downlink bandwidth. In the uplink time slot of the NUL, the terminal device can transmit uplink data by using NUL. In the downlink time slot of the NUL, the terminal device can transmit uplink data by using SUL link. The SUL can be implemented by a Sub-3G frequency band.

[0102] For example, FIG. 3 shows a schematic diagram of NUL 2Tx and SUL 1Tx uplink combination. As shown in FIG. 3, D is used to represent a downlink time slot, U is used to represent an uplink time slot, and G is used to represent a switching time slot for uplink and downlink switching. The frequency band of the NUL can be 3.5G, and the frequency band of the SUL can be 2.1G. In the uplink time slot of the NUL, the terminal device can transmit uplink data by using NUL 2Tx. In the downlink time slot of the NUL, the terminal device can transmit uplink data by using SUL 1Tx.

[0103] The super uplink can increase the uplink bandwidth by transmitting uplink data in all time slots without reducing the downlink bandwidth and without reducing the MIMO bandwidth of the uplink time slot of the NUL, so as to meet the transmission requirements of various large-bandwidth uplink services.

[0104] The configuration of the super uplink time slot is similar to the time slot configuration shown in FIG. 1. For example, FIG. 4 shows a schematic diagram of a super uplink time slot configuration. As shown in FIG. 4, the time slot configuration of TDD is 8:2. In the first 8 time slots, the NUL is a downlink time slot, and the SUL is an uplink time slot. In the last 2 time slots, the NUL is an uplink time slot, and the SUL is an uplink time slot.

[0105] In the first 8 time slots, the terminal device can transmit uplink data using the SUL, and in the last 2 time slots, the terminal device can transmit uplink data using the NUL.

[0106] Although an uplink is added in the TDD cell, for the terminal device, random access, mobility management, and the like after the super uplink is started are the same as in the ordinary TDD cell, and are completed through the TDD carrier.

[0107] 6. Time division multiplexing (TDM) scheduling

[0108] The key technology of the super uplink is TDM scheduling. In order to implement full-time slot uplink scheduling, the terminal device needs to know which time slots to transmit data through the TDD carrier and which time slots to transmit data through the SUL carrier. In some examples, the subcarrier spacing of the TDD carrier can be 30 kHz, and the subcarrier spacing of the SUL carrier can be 15 kHz.

[0109] The super uplink transmits uplink data in the Sub-3G spectrum and the C-Band spectrum by time division. In the uplink time slots of the C-Band spectrum, the C-Band spectrum is used for uplink data transmission. In the downlink time slots of the C-Band spectrum, the idle Sub-3G spectrum is used for uplink data transmission, so that uplink data can be transmitted in full time slots.

[0110] For a terminal device that has implemented the uplink and downlink decoupling function, the near point uses the NUL link, and the far point uses the SUL link. At the same time, only one uplink can be selected, and the two links cannot be scheduled at the same time. The near point uses the NUL link, and the far point uses the SUL link.

[0111] Exemplarily, FIG. 5 shows a schematic diagram of super uplink and downlink transmission. As shown in FIG. 5, the communication system includes a network device 510, a terminal device 520, and a terminal device 530. The terminal device 520 and the terminal device 530 are both within the network coverage of the network device 510.

[0112] In FIG. 5, the terminal device 520 is in an uplink good coverage area. The terminal device 530 is in an uplink limited coverage area. In other words, the terminal device 520 is in the near point, and the terminal device is in the far point.

[0113] The network device 510 can use the C-Band spectrum to transmit downlink signals to the terminal device 520 and the terminal device 530. The terminal device 520 can use the C-Band spectrum to transmit uplink signals to the network device 510. The terminal device 530 can use the idle Sub-3G spectrum to transmit uplink signals to the network device 510.

[0114] The above uplink and downlink decoupling method can be used to solve the far point uplink coverage problem and has gain for users at the far point of the cell. For users at the near point, data is still transmitted using NUL, and there is no change in user experience.

[0115] 7. Configuration method

[0116] In a 5G network, there are multiple configuration methods for network devices to issue physical layer parameters to terminal devices, such as static configuration, semi-static configuration, and dynamic configuration.

[0117] The static configuration method is defined as radio resource control (RRC) signaling configuration update taking effect. That is, the parameters sent by the network device to the terminal device are parsed by the RRC layer and then issued to the physical layer.

[0118] The semi-static configuration method is that the network device issues RRC configuration parameters to the terminal device, but does not activate them; after the terminal device receives the downlink control information (DCI) instruction, it reports the new radio media access control (NMAC) and then issues an activation command.

[0119] In some examples, the activation time point can be 3 milliseconds (ms) after the terminal device receives the DCI instruction, that is, there is a delay of at least 3 ms or more from the reception of the DCI instruction to the actual taking effect.

[0120] The dynamic configuration method is DCI scheduling, from receiving to transmitting in accordance with the processing capability 1 / processing capability 2 capability scheduling, with a scheduling advance amount, and the transmission interval from receiving to transmitting is not less than the scheduling advance amount.

[0121] In the standard protocol, the NUL+SUL combination defined in the R15 protocol is NUL 1Tx channel transmission and SUL 1Tx channel transmission. The NUL+SUL combination defined in the R16 protocol is NUL 2Tx channel transmission and SUL 1Tx channel transmission. The NUL+SUL combination defined in the R17 protocol is NUL 2Tx channel transmission and SUL 2Tx channel transmission.

[0122] Super uplink can meet the high rate requirements of near points and the coverage requirements of far points. Therefore, when the terminal device and the network device both support super uplink and the terminal device enters a connected state service, the network device can configure the terminal device with a super uplink working mode.

[0123] The service type initiated by the terminal device is random, and the size requirement of data traffic is also random. For example, when a user is making a call, he / she may need to browse a webpage, download an application, upload a file, or reply a message. The traffic required by the terminal device dynamically changes according to the requirement at any time, and the network generally does not dynamically and real-time configure different RRC carrier resources according to the service type.

[0124] In order to adapt to the large traffic requirement of the terminal device at any time and any place, after the terminal device accesses the network device, the network device can send a configuration according to the maximum capability reported by the terminal device to the terminal device. In this way, when the terminal device performs different types of services, the network device can not need to reconfigure the RRC carrier resources of the terminal device according to the service type. Therefore, after the terminal device supporting NUL+SUL reports the capability to the network device, the network device can configure the RRC carrier resources of the terminal device according to the maximum capability reported by the terminal device, so as to facilitate the terminal device to meet the service requirement when a large traffic bursts.

[0125] In a scenario with a small number of users, the network device issues a configuration with service guarantee to the terminal device, and also configures a periodic signal / channel for the terminal device to report, so as to facilitate the network device to accurately detect and perceive the wireless environment channel quality of the terminal device in the air interface in real time.

[0126] For example, in order to adapt to the dynamic change of the service quality of the terminal device, the network device can configure the FDD or TDD bandwidth for the terminal device, and also configure the SRS transmission and CSI measurement reporting for the FDD or TDD of the terminal device in the case of small voice traffic (not more than 500 Kbps traffic level) and network resource allowing. The CSI measurement reporting can be carried in the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH).

[0127] Under this configuration, the terminal device can experience smooth network rate in real time, the network device maximizes the entire uplink and downlink traffic, and the network device does not generate RRC configuration / reconfiguration for a specific terminal device due to different service switching of the terminal device, and frequently interrupts the service transmission configuration / reconfiguration signaling. However, the power consumption of the terminal device is high.

[0128] This is because, in the voice under small flow (for example, flow does not exceed 500Kbps level), network equipment is configured with NUL+SUL carrier resource to terminal equipment, regardless of what service, terminal equipment is according to NUL+SUL carrier switching work, then network configuration NUL+SUL carrier various periodic channel resource of terminal equipment, also need to send according to the requirement of network equipment configuration.

[0129] And in the voice under small flow (for as flow is about 10Mbps level), in the condition of good signal, network equipment is configured with very dense SRS sending to NUL and SUL of terminal equipment. NUL is configured with 5ms periodical SRS resource;SUL is also configured with 5ms periodical SRS resource.

[0130] In this way, whether it is under large flow or small flow, terminal equipment exists 5ms SRS period emission on SUL and NUL, which leads to large power consumption of terminal equipment.

[0131] That is, the large power consumption of terminal equipment is because, in the case of good signal and small flow, terminal equipment sends NUL and SUL periodically according to the configuration of network equipment, such as dense, periodic SRS sending and periodic CSI measurement reporting. Such dense and periodic emission events lead to waste of terminal equipment power consumption and affect the final experience of terminal equipment.

[0132] Actually, in the case of good signal and small flow, terminal equipment sends SRS and CSI densely according to the configuration of network equipment, but there is no PUSCH and PUCCH sending. SUL has no downlink channel, and SRS sending on SUL is mainly for network to allocate uplink PUSCH / PUCCH channel to evaluate wireless environment, or to monitor the wireless channel environment of SUL carrier and NUL carrier in real time, and to compare and evaluate, finally determine whether to select NUL carrier sending or SUL carrier sending, which can maximize the uplink and downlink flow of the whole network. If there is no or little PUSCH and PUCCH channel sending, SRS and CSI can not be sent densely.

[0133] The above is an example of super uplink NUL+SUL scenario, and the configuration of dense SRS and CSI period will increase the power consumption of terminal equipment. In other scenarios, for example, the scenario of terminal equipment supporting multiple carriers, network equipment can configure downlink multiple carriers and / or uplink multiple carriers, and in this multiple carrier scenario, each carrier may also be configured with dense SRS and CSI period, which leads to the increase of power consumption of terminal equipment.

[0134] Therefore, the embodiment of the present application provides a method and device for transmitting uplink signals. The network device instructs the terminal device to transmit uplink signals according to a first period. The terminal device can transmit uplink signals according to a second period according to the requirements of services and / or power consumption. The length of the second period can be greater than the length of the first period. In this way, the power consumption of the terminal device can be reduced without affecting services.

[0135] It can be understood that the embodiment of the present application can be applied to various scenarios such as a single-carrier scenario, a super uplink NUL+SUL scenario, and a multi-carrier scenario.

[0136] Next, the method provided by the embodiment of the present application will be described in detail in combination with FIGS. 6-9. The embodiment shown by the embodiment of the present application shows the method provided by the embodiment of the present application from the perspective of device interaction. The specific form and number of each device shown are only examples and should not constitute any limitation on the implementation of the method provided by the embodiment of the present application. Next, the method of the embodiment of the present application will be described in detail taking the network device and the terminal device as the main body.

[0137] It should be understood that the terminal device can be the terminal device itself, a chip, a chip system, or a processor supporting the terminal device to implement the method provided by the embodiment of the present application, or a logic module or software capable of implementing all or part of the terminal device. The network device can be the network device itself, a chip, a chip system, or a processor supporting the network device to implement the method provided by the embodiment of the present application, or a logic module or software capable of implementing all or part of the network device, which is not limited by the present application.

[0138] Exemplarily, FIG. 6 shows a schematic flowchart of a method for transmitting uplink signals provided by the embodiment of the present application. The method can be applied to the communication system shown in FIG. 5, but the embodiment of the present application is not limited thereto. As shown in FIG. 6, the method can include the following steps:

[0139] S601, the network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information. The first indication information is used to indicate that the transmission period of the uplink signal includes a first period.

[0140] The network device can be the network device 510 in FIG. 5, and the terminal device can be the terminal device 520 or the terminal device 530 in FIG. 5, which is not limited by the embodiment of the present application.

[0141] The uplink signal is transmitted periodically, and the transmission period can include a first period. The length of the first period is not limited by the embodiment of the present application.

[0142] In some examples, the uplink signal can be SRS and / or CSI, and the first period can be 4 ms, 5 ms, or 6 ms, etc.

[0143] S602. In a case where the first condition is met, the terminal device sends an uplink signal to the network device, and a sending period of the uplink signal is a second period, and a time length of the second period is greater than a time length of the first period, and the first condition is related to power consumption and / or service of the terminal device.

[0144] Generally, the terminal device needs to send an uplink signal according to the first period indicated by the network device, but the time length of the first period is short, and if the uplink signal is sent according to the time length, although it is beneficial to the implementation of the service, it will increase the power consumption of the terminal device. Therefore, in the embodiments of the present application, the terminal device can send the uplink signal using the second period with a longer time length than the first period in a case where the first condition is met, instead of using the first period indicated by the network device. In this way, it is beneficial to meet the needs of the service and reduce the power consumption of the terminal device.

[0145] The first condition has multiple possible implementations.

[0146] In some examples, the first condition is related to the power consumption of the terminal device. When the power consumption of the terminal device reaches a set threshold, it means that the power consumption is large, and the uplink signal needs to be sent using the second period with a longer time length. In this way, it is beneficial to reduce the power consumption of the terminal device.

[0147] In other examples, the first condition is related to the service of the terminal device. Some services do not require large traffic and do not need to send the uplink signal frequently, and at this time the terminal device can send the uplink signal using the second period with a longer time length. In this way, it is beneficial to meet the needs of the service while reducing the power consumption of the terminal device.

[0148] In yet other examples, the first condition can be related to the power consumption and service of the terminal device. The power consumption threshold values corresponding to different services can be different or the same. When the terminal device runs some services, it can judge whether the corresponding power consumption condition is met. If not, it means that the power consumption is within a controllable range, and the terminal device can send the uplink signal according to the first period. If it is met, it means that the power consumption is large, and the terminal device can send the uplink signal according to the second period.

[0149] In this way, it is beneficial to meet the needs of the service while reducing the power consumption of the terminal device.

[0150] Optionally, the first condition can also be related to the performance of the terminal device, which can include bit error rate, signal quality, etc.

[0151] Exemplarily, the first condition can be related to power consumption, service and performance of the terminal device. The first condition is a condition set for balancing power consumption and performance of the terminal device for different services.

[0152] When the terminal device runs some services, the terminal device needs to send uplink signals according to the first period based on the first indication information. In this process, the terminal device can determine whether the first condition is met. If not, it means that the service performance requirement is prioritized over the power consumption requirement. If yes, it means that the service performance is within a controllable range, and the power consumption can be saved. Therefore, the terminal device can send uplink signals according to the second period.

[0153] The length of the second period is greater than that of the first period. In some examples, the uplink signal can be SRS and / or CSI, and the second period can be 10 ms, 8 ms, 12 ms or longer, etc. The second period can be set by the terminal device, or can be indicated by the network device, or can be agreed by the protocol, and the embodiments of the present application do not limit this.

[0154] The terminal device can send uplink signals according to the same second period on all carriers, or can send uplink signals according to different second periods on different carriers or different frequency bands, and the embodiments of the present application do not limit this.

[0155] If the terminal device sends uplink signals according to the same second period on all carriers, it is simple. For example, the first period is 5 ms, and the second period is 8 ms. The terminal device can send uplink signals according to 8 ms on all carriers.

[0156] If the terminal device sends uplink signals according to different second periods on different carriers or different frequency bands, it is more flexible. For example, the first period is 5 ms, and the second period includes 10 ms and 8 ms. The terminal device can send uplink signals according to 10 ms on carrier 1 or frequency band 1, and can send uplink signals according to 8 ms on carrier 2 or frequency band 2.

[0157] In this example, the correspondence between the carrier or frequency band and the second period can be pre-defined by the protocol or indicated by the network device, and the embodiments of the present application do not limit this.

[0158] In addition, the terminal device can also send uplink signals according to the second period on some carriers or frequency bands, and can send uplink signals according to the first period on other carriers or other frequency bands, that is, the second period can take effect on some specific carriers or frequency bands. Which carriers or frequency bands take effect can be pre-defined by the protocol or indicated by the network device, and the embodiments of the present application do not limit this.

[0159] In the above examples, the terminal device transmits the uplink signal on all carriers according to the same second period, which can be referred to as UE-level transmission. The terminal device transmits the uplink signal on different carriers according to different second periods, or transmits the uplink signal on some carriers according to the second period and transmits the uplink signal on other carriers according to the first period, which can be referred to as carrier-level transmission. The terminal device transmits the uplink signal on different frequency bands according to different second periods, or transmits the uplink signal on some frequency bands according to the second period and transmits the uplink signal on other frequency bands according to the first period, which can be referred to as frequency band-level transmission.

[0160] The terminal device can transmit the uplink signal using the second period with a longer time length than the first period when the first condition is met, which is beneficial to meet the requirements of the service and reduce the power consumption of the terminal device.

[0161] In the method shown in FIG. 6, the terminal device can transmit the uplink signal using the second period with a longer time length than the first period indicated by the network device, which indicates that the terminal device supports discontinuous transmission of the uplink signal. The terminal device can report to the network device that it supports the feature of discontinuous transmission of the uplink signal. The network device can record that the terminal device supports discontinuous transmission of the uplink signal, so that the feature of the terminal device can be started subsequently, or the network device can not determine that the terminal device transmits the signal abnormally or the channel environment deteriorates when the uplink signal is not received in the first period, and thus reconfiguration is not performed.

[0162] In some examples, the feature of the terminal device supporting discontinuous transmission of the uplink signal can be embodied by an identifier or a flag. The terminal device can send the identifier or the flag to the network device. The network device can store the identifier or the flag after receiving it, so as to be used subsequently.

[0163] The uplink signal can include multiple signals, for example, the uplink signal can include SRS and CSI. In some examples, the terminal device can support discontinuous transmission of some signals such as SRS, and support continuous transmission of other signals such as CSI.

[0164] Optionally, the method shown in FIG. 6 can further include that the network device sends second indication information to the terminal device, the second indication information being used to indicate that discontinuous reception of the uplink signal is supported; and the S602 of transmitting the uplink signal in the case where the first condition is met can include that the terminal device can transmit the uplink signal in the case where the first condition is met based on the second indication information.

[0165] The second indication information is used to indicate that the network device supports discontinuous reception of the uplink signal, that is, the network device supports discontinuous transmission (DTX). In this way, the terminal device can send the uplink signal to the network device without using the indicated first period when the network device can support discontinuous reception of the uplink signal. In this way, the network device can determine that the terminal device does not send the uplink signal at the time point when the network device does not receive the uplink signal in the specified period, instead of considering that the terminal device abnormally transmits the signal or the channel environment deteriorates, and thus the network device will not perform reconfiguration, which is beneficial to system stability.

[0166] The second indication information can be the same as the first indication information or different from the first indication information, and the embodiments of the present application do not limit the same.

[0167] If the second indication information is the same as the first indication information, one indication information can indicate multiple information, which is beneficial to saving signaling overhead.

[0168] The second indication information is used to indicate that the network device supports discontinuous reception of the uplink signal. In an example, a field of the second indication information is used to indicate that the network device supports discontinuous reception of the uplink signal. For example, the field can be defined as PeriodSignalDTXFlag.

[0169] The network device can send the PeriodSignalDTXFlag to the terminal device, and the PeriodSignalDTXFlag is used to indicate that the network device supports discontinuous reception of the uplink signal. Based on the PeriodSignalDTXFlag, the terminal device can send the uplink signal using a second period.

[0170] In some examples, the PeriodSignalDTXFlag can be carried in the RRC signaling. In this way, the field is carried in the existing signaling, which is beneficial to saving signaling resources.

[0171] In the above method, the network device can support discontinuous reception of all periodically transmitted uplink signals, or can specify discontinuous reception of some periodically transmitted uplink signals.

[0172] For example, the periodically transmitted uplink signal can include SRS and CSI. The network device can support discontinuous reception of the SRS or the CSI. For example, the field PeriodSignalDTXFlag-SRS can be used to indicate that the network device supports discontinuous reception of the SRS, and the field PeriodSignalDTXFlag-CSI can be used to indicate that the network device supports discontinuous reception of the CSI. The network device can support discontinuous reception of the SRS is taken as an example for description.

[0173] The network device can send second indication information to the terminal device, and the second indication information can be used to indicate support of discontinuous reception SRS. A field PeriodSignalDTXFlag-SRS in the second indication information can be used to indicate support of discontinuous reception SRS. Based on the PeriodSignalDTXFlag-SRS, the terminal device can send SRS using a second period.

[0174] In some possible implementations, in the method shown in FIG. 6, the network device sends first indication information to the terminal device, and the first indication information can indicate a target carrier or a target frequency band in addition to indicating that the sending period of the uplink signal includes the first period. In this way, the S602 described above, in the case where the first condition is met, sending the uplink signal can include: in the case where the first condition is met, the terminal device sending the uplink signal on the target carrier or the target frequency band.

[0175] The second indication information is also used to indicate the target carrier or the target frequency band, which is beneficial to saving signaling overhead. In other examples, the target carrier or the target frequency band can also be indicated by the second indication information or information different from the first indication information and the second indication information, and the embodiments of the present application do not make any limitation in this regard.

[0176] In this example, the terminal device can send the uplink signal on a carrier or a frequency band other than the target carrier or the target frequency band according to the first period, or the terminal device can send the uplink signal on a carrier or a frequency band other than the target carrier or the target frequency band according to another second period, that is, different frequency bands or frequency bands correspond to different second periods.

[0177] The terminal device can send the uplink signal on the carrier or the frequency band indicated by the network device, which is more flexible.

[0178] Optionally, in the method shown in FIG. 6, the length of the second period is greater than the length of the first period. In some examples, the length of the second period can be less than or equal to the length of the third period. That is, the third period is the maximum period.

[0179] The third period can be indicated by the network device, or can be set by the terminal device based on conditions such as traffic and power consumption, or can be agreed by a protocol, and the embodiments of the present application do not make any limitation in this regard.

[0180] For example, the network device can indicate, through the first indication information described above, that the maximum period for sending the uplink signal is the third period. In this way, the first indication information indicates that the maximum period for sending the uplink signal is the third period, and indicates that the period for sending the uplink signal includes the first period, and multiple information is indicated by one indication information, which is beneficial to saving signaling overhead.

[0181] The uplink signal can include multiple signals. For example, the uplink signal can include SRS and CSI. The maximum transmission periods of the SRS and the CSI can be different or the same.

[0182] If the maximum transmission periods of different signals are the same, the network device can indicate one maximum transmission period, which is beneficial to saving field overhead.

[0183] If the maximum transmission periods of different signals are different, the network device can indicate the maximum transmission periods of different signals respectively. The maximum transmission periods of different signals can be indicated by one information or different information, which is not limited in the embodiments of the present application.

[0184] In some possible examples, the maximum periods of the uplink signals transmitted on all carriers can be the third period. Alternatively, the maximum periods of the uplink signals transmitted on different carriers or different frequency bands can be different third periods, which is not limited in the embodiments of the present application.

[0185] If the maximum periods of the uplink signals transmitted on all carriers are the third period, the implementation is simple.

[0186] If the maximum periods of the uplink signals transmitted on different carriers or different frequency bands are different third periods, the flexibility is stronger. In this example, the correspondence between the carrier or the frequency band and the third period can be protocol predefined or indicated by the network device, which is not limited in the embodiments of the present application.

[0187] In addition, the maximum period of the uplink signal transmitted on some carriers or frequency bands can be the third period, and the maximum period of the uplink signal transmitted on other carriers or other frequency bands can not be limited by the third period.

[0188] Optionally, in the method shown in FIG. 6, before S602, in the case of satisfying the first condition, the method further includes: the network device sends a second condition to the terminal device, the priority of the second condition is higher than the priority of the first condition, the second condition is related to uplink and downlink traffic and / or service; in the case of satisfying the second condition, the uplink signal is transmitted; or S602, in the case of satisfying the first condition, the uplink signal is transmitted, including: in the case of not satisfying the second condition and satisfying the first condition, the uplink signal is transmitted.

[0189] It can be understood that the second condition is indicated by the network device, and the priority of the second condition can be higher than the priority of the first condition. If the second condition is met, the terminal device can send the uplink signal using the second period regardless of whether the first condition is met. If the second condition is not met, the uplink signal can be sent using the second period if the first condition is met.

[0190] The second condition is related to uplink and downlink traffic and / or services.

[0191] In some examples, the second condition can be related to uplink and downlink traffic. The uplink and downlink traffic can be embodied by one or more conditions of data traffic, scheduling frequency, signal-to-noise ratio of uplink and downlink signals, and received power of uplink and downlink signals.

[0192] For example, the second condition can include one or more of the following: data traffic is less than a traffic threshold, scheduling frequency is less than a frequency threshold, signal-to-noise ratio SNR of uplink and downlink signals is less than a signal-to-noise ratio threshold, and received power of uplink and downlink signals is less than a power threshold.

[0193] If the second condition is met, the uplink signal does not need to be frequently sent, and the terminal device can send the uplink signal using the second period. If the second condition is not met but the first condition is met, it means that the uplink signal does not need to be frequently sent, and the terminal device can send the uplink signal using the second period.

[0194] In this way, it is beneficial to reduce the power consumption of the terminal device while meeting the service.

[0195] The conditions of uplink and downlink traffic corresponding to different services can be different. In this way, the flexibility is stronger.

[0196] In some possible examples, the second condition can be related to carriers.

[0197] For example, the second condition is the same on all configured carriers. Alternatively, different carriers or frequency bands can correspond to different second conditions. Alternatively,

[0198] If different carriers correspond to different second conditions, the network device can indicate each carrier and the second condition corresponding to each carrier to the terminal device. The terminal device can send the uplink signal on the carrier corresponding to the second condition if the second condition is met, and the period of the uplink signal is the second period.

[0199] If different frequency bands correspond to different second conditions, the network device can indicate each frequency band and the second condition corresponding to each frequency band to the terminal device. The terminal device can send the uplink signal on the frequency band corresponding to the second condition if the second condition is met, and the period of the uplink signal is the second period.

[0200] To better understand the above method, the following embodiments of the application introduce a specific example in combination with FIG. 7.

[0201] Exemplarily, FIG. 7 shows a schematic flowchart of a method for transmitting an uplink signal according to an embodiment of the application. The method can be applied to the communication system shown in FIG. 5, but the embodiments of the application are not limited thereto. As shown in FIG. 7, the method can include the following steps:

[0202] S701, the network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information. The first indication information is used to indicate that the transmission period of the uplink signal includes a first period.

[0203] This step can refer to S601 described above, and will not be described here again.

[0204] S702, the network device sends a third period and a second condition to the terminal device, and correspondingly, the terminal device receives the third period and the second condition.

[0205] The third period is the maximum period for transmitting the uplink signal. If the second condition is met, it means that the uplink signal is transmitted using a period longer than the first period.

[0206] S703, the network device sends second indication information to the terminal device, and correspondingly, the terminal device receives the second indication information. The second indication information is used to indicate that the discontinuous reception of the uplink signal is supported.

[0207] The network device can discontinuously receive the uplink signal, and informs the terminal device through the second indication information, so that the terminal device discontinuously transmits the uplink signal.

[0208] S701 to S703 can be executed in parallel or sequentially, and the execution order of the three steps is not limited by the embodiments of the application.

[0209] S704, the terminal device sends a flag indicating that the discontinuous transmission of the uplink signal is supported to the network device.

[0210] The terminal device supports the discontinuous transmission of the uplink signal, and can

[0211] The flag indicating that the discontinuous transmission of the uplink signal is supported informs the network device, so that the network device receives the uplink signal.

[0212] S704 can be executed before or after S701 to S703, and the embodiments of the application do not limit this.

[0213] S705, the network device stores the flag indicating that the discontinuous transmission of the uplink signal is supported.

[0214] The network device stores the flag, so that the network device discontinuously receives the uplink signal from the terminal device.

[0215] S706, the terminal device judges whether the second condition is met.

[0216] The second condition can refer to the above description, which will not be repeated here.

[0217] S707, in the case where the second condition is met, the terminal device sends an uplink signal to the network device, and correspondingly, the network device can receive the uplink signal in the second period. The transmission period of the uplink signal is the second period, and the length of the second period is greater than the length of the first period.

[0218] S708, the network device does not receive the uplink signal in the first period, which can determine that the terminal device does not send the uplink signal at this time point, rather than considering that the terminal device transmits the signal abnormally or the channel environment deteriorates.

[0219] In this way, in the case where the network supports DTX (discontinuous reception), the terminal device communicates with the network through the air interface capability, and in the case where the second condition of the network is met, the terminal device can use the second period longer than the length of the first period to send the uplink signal, which is beneficial to reduce the power consumption of the terminal device.

[0220] In addition to the above-mentioned method, the embodiment of the application can also provide a transmission method of an uplink signal. In the method, the network device can indicate a plurality of periods, including a first period and a second period. The network device can indicate the terminal device to use a certain one of the plurality of periods according to the service and / or uplink and downlink traffic, or the terminal device requests the period required according to the service and / or power consumption.

[0221] Exemplarily, in the method shown in the above-mentioned FIG. 6, the first indication information is also used to indicate that the transmission period of the uplink signal further includes the second period; the S602, in the case where the first condition is met, sending the uplink signal, includes: in the case where the first condition is met, the terminal device sends a first request message to the network device, the first request message is used to request to use a period longer than the length of the first period to send the uplink signal; the network device can send third indication information to the terminal device based on the first request message, the third indication information is used to indicate that the transmission period of the uplink signal is the second period; based on the third indication information, the terminal device can send the uplink signal, and the transmission period of the uplink signal is the second period.

[0222] The network device can indicate a plurality of periods including the first period and the second period through the first indication information. The terminal device can not actively switch the period, and can request the network device to switch the period and give a suggestion if the period indicated by the network device does not meet the requirements of the service and / or power consumption, i.e., request to use a period longer than the first period to transmit the uplink signal in the case of meeting the first condition through the first request message. The network device can indicate the terminal device that the transmission period of the uplink signal is the second period based on the request of the terminal device.

[0223] In this way, the terminal device can negotiate with the network device to use a long period to transmit the uplink signal, which is beneficial to reduce the power consumption of the terminal device.

[0224] Optionally, the above method can further include: in the case of not meeting the first condition, the terminal device sends a second request message to the network device, the second request message being used to request to use a period shorter than the second period to transmit the uplink signal; the network device can send fourth indication information to the terminal device based on the first request message, the fourth indication information being used to indicate that the transmission period of the uplink signal is the first period; and the uplink signal is transmitted based on the fourth indication information, and the transmission period of the uplink signal is the first period.

[0225] The terminal device can request to switch the period according to the real-time change of the requirements of the service and / or power consumption. If the second period indicated by the network device does not meet the requirements of the service and / or power consumption, the terminal device can request the network device to switch the period and give a suggestion, i.e., request to use a period shorter than the second period to transmit the uplink signal in the case of not meeting the first condition through the second request message. The network device can indicate the terminal device that the transmission period of the uplink signal is the first period based on the request of the terminal device.

[0226] In this way, the terminal device can negotiate with the network device to use a short period to transmit the uplink signal, which is beneficial to improve the performance of the terminal device.

[0227] In order to better understand the above examples, a specific example will be introduced in combination with FIG. 8.

[0228] Exemplarily, FIG. 8 shows a schematic flowchart of a method for transmitting an uplink signal provided by an embodiment of the present application. The method can be applied to the communication system shown in FIG. 5, but the embodiments of the present application are not limited thereto. As shown in FIG. 8, the method can include the following steps:

[0229] S801, the network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information. The first indication information is used to indicate that the transmission period of the uplink signal includes the first period and the second period.

[0230] The transmission period of the uplink signal can further include a period other than the first period and the second period. The example is described by taking the first period and the second period as an example.

[0231] The first indication information is used to indicate that the transmission period of the uplink signal includes the first period and the second period, and the first period can be used by default to transmit the uplink signal, so that the first period is used to transmit the uplink signal without separate indication, which is beneficial to saving signaling overhead.

[0232] The transmission period of the uplink signal can be applicable to the uplink signal transmitted on all carriers. Alternatively, the transmission period of the uplink signal is different on different carriers or different frequency bands. Alternatively, the transmission period of the uplink signal is applicable to a specific carrier or frequency band.

[0233] S802, the terminal device determines whether the first condition is met.

[0234] The first condition can refer to the first condition in S602 in FIG. 6 described above, which will not be described here.

[0235] In the process of transmitting the uplink signal by the terminal device using the first period, it can be determined whether the first condition is met.

[0236] If the first condition is not met, the terminal device can always transmit the uplink signal using the first period.

[0237] S803, in the case where the first condition is met, the terminal device can send a first request message to the network device, and correspondingly, the network device receives the first request message. The first request message is used to request to transmit the uplink signal using a period longer than the time length of the first period.

[0238] In this example, the terminal device cannot actively switch the period, and if the period indicated by the network device does not meet the needs of the service and / or power consumption, the terminal device can request the network device to switch the period and give a suggestion, that is, in the case where the first condition is met, the first request message is used to request to transmit the uplink signal using a period longer than the time length of the first period.

[0239] S804, based on the first request message, the network device can determine whether the condition of lengthening the period is met.

[0240] The network device can determine whether to use a period longer than the first period to send the uplink signal according to the information reported by the terminal device, that is, determine whether the condition of lengthening the period is met, and if so, send the third indication information to the terminal device, that is, perform S805. The information reported by the terminal device can include SNR, RSRP, quality of experience (QoE), power headroom report (PHR), one or more of the information of the signal received by the network device from the terminal device, and the data flow and data type between the network device and the terminal device, which is reported by the terminal device to the network device during the operation of the service. The data type between the network device and the terminal device can include voice data, live service data, file transmission type data, etc. S805, if the condition of lengthening the period is met, the network device can send the third indication information to the terminal device, and the third indication information is used to indicate that the transmission period of the uplink signal is the second period.

[0241] If the condition of lengthening the period is met, the network device can select a period longer than the first period from a plurality of periods, for example, the second period, and indicate the transmission period of the uplink signal as the second period through the third indication information.

[0242] In this way, under the condition of lengthening the period, the network device can send the third indication information, which is beneficial to improve the accuracy of period indication compared with directly sending the third indication information based on the first request message.

[0243] S806, the terminal device determines whether the first condition is met.

[0244] The terminal device can determine whether the first condition is met during the process of using the second period to send the uplink signal.

[0245] S807, in the case where the first condition is not met, the terminal device can send a second request message to the network device, and correspondingly, the network device receives the second request message. The second request message is used to request to use a period shorter than the second period to send the uplink signal.

[0246] In this example, the terminal device cannot actively switch the period, and if the period indicated by the network device does not meet the needs of the service and / or power consumption, the terminal device can request the network device to switch the period and give a suggestion, that is, in the case where the first condition is met, the terminal device requests to use a period shorter than the second period to send the uplink signal through the second request message.

[0247] S808, based on the second request message, the network device can determine whether the condition of shortening the period is met.

[0248] The condition for shortening the period can be related to one or more of the information of SNR, RSRP, QoE, PHR, the signal received by the network device from the terminal device, and the data flow and data type between the network device and the terminal device. In the case where the condition for shortening the period is met, the network device can send fourth indication information to the terminal device, i.e., perform S809.

[0249] S809, in the case where the condition for shortening the period is met, the network device can send fourth indication information to the terminal device, the fourth indication information being used to indicate that the transmission period of the uplink signal is the first period.

[0250] In the case where the condition for shortening the period is met, the network device can select a period shorter than the length of the second period, for example, the first period, from a plurality of periods, and can indicate the transmission period of the uplink signal as the first period through the fourth indication information.

[0251] In this way, in the case where the first condition is met, the terminal device selects a longer period to transmit the uplink signal by negotiating with the network device; in the case where the first condition is not met, the terminal device selects a shorter period to transmit the uplink signal by negotiating with the network device, and by flexibly selecting the configuration mode of long / short period, the energy saving requirement of the terminal device is facilitated.

[0252] In the example shown in FIG. 8, the terminal device requests to switch the period. In another example, the network device can monitor the signal quality and channel flow (or uplink / downlink flow) of the terminal device in real time, and according to the comprehensive judgment of the service, signal quality and channel flow, indicate the appropriate period to the terminal device.

[0253] Exemplarily, the network device sends first indication information to the terminal device, the first indication information being used to indicate that the transmission period of the uplink signal includes the first period and the second period. The terminal device can use the first period to transmit the uplink signal by default. During the communication process between the network device and the terminal device, the network device can judge in real time whether the preset condition is met, and in the case where the preset condition is met, can instruct the terminal device to use the second period to transmit the uplink signal. During the process in which the terminal device uses the second period to transmit the uplink signal, the network device can judge in real time whether the preset condition is met, and in the case where the preset condition is not met, can instruct the terminal device to use the first period to transmit the uplink signal.

[0254] It can be understood that when the transmission period of the uplink signal includes three periods, different periods can be preset with corresponding preset conditions, and in the case where the corresponding preset condition is met, the network device can instruct to use the corresponding period.

[0255] Optionally, in the example shown in FIG. 8, the network device can indicate, by the third indication information, that the transmission period of the uplink signal is the second period, and can indicate, by the fourth indication information, that the transmission period of the uplink signal is the first period. The specific indication manner can be semi-static MAC indication, or can be dynamic indication in the form of DCI, which is not limited in the embodiments of the present application.

[0256] The specific implementation of the semi-static MAC indication and the dynamic indication in the form of DCI can refer to the above term explanation part, which will not be repeated here.

[0257] In addition to the above-mentioned method, the embodiments of the present application also provide a transmission method of an uplink signal, which is beneficial to reducing the detection load of the network device while reducing the power consumption of the terminal device.

[0258] Exemplarily, FIG. 9 shows a schematic flow chart of a transmission method of an uplink signal provided by the embodiments of the present application. The method can be applicable to the communication system shown in FIG. 5, but the embodiments of the present application are not limited thereto. As shown in FIG. 9, the method can include the following steps:

[0259] S901, the network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information. The first indication information is used to indicate that the transmission period of the uplink signal includes the first period.

[0260] S902, the terminal device judges whether a first condition is met, and the first condition is related to the power consumption and / or service of the terminal device.

[0261] S903, in the case where the first condition is met, the terminal device can send fifth indication information to the network device, and the fifth indication information is used to indicate that the second period is used to transmit the uplink signal.

[0262] S904, the terminal device can send the uplink signal to the network device, and the transmission period of the uplink signal is the second period, and the time length of the second period is greater than that of the first period.

[0263] S905, in the communication process between the terminal device and the network device, the terminal device judges whether the first condition is met, and the first condition is related to the power consumption and / or service of the terminal device.

[0264] S906, in the case where the first condition is not met, the terminal device can send indication information to the network device to stop using the second period to transmit the uplink signal, and can use the first period to transmit the uplink signal.

[0265] In this way, the terminal device reports to the network device when starting to use the longer period, and informs the network device to use the longer period. After receiving the indication, the network device can start discontinuous detection, which is beneficial to reduce the detection load of the network device. The terminal device reports to the network device when stopping using the longer period, and informs the network device to stop using the longer period. After receiving the indication, the network device can start continuous detection, which is beneficial to improve the efficiency of receiving uplink signals.

[0266] In some examples, the terminal device can only report starting to use the longer period or only report stopping using the longer period, and the embodiments of the present application do not limit this.

[0267] The uplink signals include multiple signals. When the signals start to use the longer period and / or stop using the longer period, the indication can be made on the same information or different information, and the embodiments of the present application do not limit this.

[0268] If the indication is made on the same information, it is beneficial to save signaling overhead. If the indication is made on different information, it is more flexible.

[0269] Reporting starting to use the longer period and / or reporting stopping using the longer period can be applied to uplink signals transmitted on all carriers or uplink signals transmitted on specific carriers or frequency bands, and the embodiments of the present application do not limit this.

[0270] In this way, reporting starting to use the longer period and / or reporting stopping using the longer period can take effect on different carriers, which is more flexible.
