Abstract

When a Scheduling Request (SR) is triggered, under the condition that a time interval between a first time domain position corresponding to the SR and a second time domain position corresponding to a physical uplink channel meets a first preset condition, a terminal device sends uplink information to a network device through the physical uplink channel, wherein the uplink information is the SR or a Buffer Status Report (BSR) corresponding to the SR. In the scheme, the network equipment receives the uplink information from the terminal equipment through the physical uplink channel, does not need to receive the SR through the uplink resource corresponding to the first time domain position, and receives the information corresponding to the second time domain position through the physical uplink channel corresponding to the second time domain position, so that the number of times that the terminal equipment sends the information to the network equipment can be reduced, the terminal equipment does not need to be always kept in a state of high-power-consumption operation due to frequent information interaction requirements, and the power consumption of the terminal equipment is reduced.

Description

Information transmission method and related equipment

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to an information transmission method and related devices.

Background

In recent years, with the development of communication technologies such as the fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G), in terminal devices such as smartphones, head mounted displays (head mounted display, HMD) or smart glasses, various services with high real-time and large data volume, such as multimedia services such as real-time video transmission, cloud Gaming (CG), extended reality (XR), etc., can be provided to users through wireless communication technologies.

In many service scenarios, frequent data interaction is required between the terminal device and the network device such as the base station, for example, the terminal device needs to upload information frequently, which results in a state that the terminal device needs to be operated with high power consumption all the time, so that the power consumption of the terminal device is high, the endurance time of the terminal device is shortened, and the use experience of a user is affected.

Disclosure of Invention

The application provides an information transmission method, which aims to solve the problem that the terminal equipment needs to be in a high-power-consumption running state all the time to cause larger power consumption because the terminal equipment needs to frequently execute data interaction operations such as uploading information and the like. The application also provides corresponding apparatus, devices, computer readable storage media, computer program products, etc.

The first aspect of the present application provides an information transmission method, where the method is applied to a terminal device or a chip of the terminal device, and the method may also be implemented by a logic module or software capable of implementing all or part of functions of the terminal device. The method comprises the following steps: when the scheduling request SR is triggered, if the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel meets a first preset condition, uplink information is sent to the network device through the physical uplink channel, where the uplink information is the SR or a buffer status report BSR corresponding to the SR.

In the first aspect, the network device receives uplink information from the terminal device through a physical uplink channel, and does not need to receive SR through an uplink resource corresponding to the first time domain location, and receives information corresponding to the second time domain location through a physical uplink channel corresponding to the second time domain location. It can be seen that, by the solution of the first aspect, the number of times that the terminal device sends information to the network device can be reduced, so that the terminal device does not need to be kept in a state of high power consumption operation all the time due to frequent information interaction requirements, thereby reducing the power consumption of the terminal device.

In a possible implementation manner of the first aspect, the first preset condition is that a time interval between the first time domain position and the second time domain position is less than or equal to a first preset duration.

In this possible implementation manner, the longest time delay that may be caused by transmitting the uplink information through the physical uplink channel does not exceed the first preset duration. Therefore, by reasonably setting the first preset duration, the terminal equipment can send the uplink information to the network equipment through the physical uplink channel under the condition that the time delay of the uplink information is kept within an acceptable range, so that the uplink information can be timely processed, and meanwhile, the interaction frequency between the terminal equipment and the network equipment can be reduced, so that the terminal equipment does not need to be kept in a state of high-power operation all the time due to frequent information interaction requirements, and the power consumption of the terminal equipment is reduced.

In a possible implementation manner of the first aspect, the method further includes: receiving configuration information from a network device; and determining a first preset duration according to the configuration information.

In a possible implementation manner of the first aspect, the terminal device is in a dormant state in which it does not monitor the physical downlink control channel PDCCH.

At present, when the terminal equipment is in a dormant state of not monitoring the physical downlink control channel PDCCH, if the terminal equipment frequently transmits data to the network equipment, the dormant state of the terminal equipment is interrupted, so that the power consumption of the terminal equipment is increased. In this possible implementation manner, when the terminal device is in a dormant state where the physical downlink control channel PDCCH is not monitored, the method of the first aspect is executed, so that the number of times that the terminal device performs uplink transmission in the dormant state can be reduced, the terminal device can keep a state with lower power consumption in a longer period of time in the dormant state, and the power consumption of the terminal device is obviously saved.

In a possible implementation manner of the first aspect, the physical uplink channel is a physical uplink control channel PUCCH; the method further comprises the steps of: transmitting at least one of the following information to the network device through the PUCCH: hybrid automatic repeat request, HARQ, feedback information, channel state information, CSI, link recovery request, LRR.

In the possible implementation manner, the designated control information such as the SR, the HARQ feedback information, the CSI, the LRR and the like can be multiplexed on the PUCCH for transmission, so that the transmission efficiency is improved, the information interaction frequency is reduced, and the power consumption of the terminal equipment is reduced.

In a possible implementation manner of the first aspect, the physical uplink channel is a physical uplink shared channel PUSCH; the method further comprises the steps of: and sending the data information to the network equipment through the PUSCH.

In the possible implementation manner, the data information and the BSR corresponding to the SR can be aggregated and transmitted, so that the transmission efficiency is improved; in addition, in the possible implementation manner, the interaction processes of the terminal equipment for sending the SR to the network equipment, the terminal equipment for receiving the uplink authorization from the network equipment and the like are canceled, and the information interaction frequency is reduced; and the terminal equipment does not need to be kept in an activated state after sending the SR to the network equipment so as to monitor the uplink authorization from the network equipment, thereby greatly reducing the power consumption of the terminal equipment.

In the following, a scenario to which the embodiments of the present application may be applied will first be described.

The embodiment of the application can be applied to a wireless communication system.

The particular type of wireless communication system is not limited herein. The wireless communication system may be a combination of one or more of a global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA) IS-95, code division multiple access (code division multiple access, CDMA) 2000, time division synchronous code division multiple access (time division multiple access-synchronous code division multiple access, TDSCDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), long term evolution (Long Term Evolution, LTE), time division duplex-long term evolution (time division duplexing-long term evolution, TDD LTE), frequency division duplex-long term evolution (frequency division duplexing-long term evolution, FDD LTE), long term evolution-enhanced (long term evolution-advanced, LTE-advanced), personal Handyphone System (PHS), 802.11-series protocol-specified wireless fidelity (wireless fidelity, wiFi), 5G mobile communication system, or new air interface (new radio, NR) communication system, etc.

One or more network devices and one or more terminal devices may be included in the wireless communication system.

The network device may be a device such as a base station having a wireless transceiving function. Illustratively, the network device may be an evolved base station (evolutional Node B, nodeB or eNB) in LTE, a base station (next generation node B, gnob or gNB) or a point of transceiver (transmission reception point, TRP) in NR, a base station for 3GPP subsequent evolution, an access node in WiFi system, a wireless relay node, a wireless backhaul node, etc. When the network device is a base station, the base station may be a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station. It will be appreciated that all or part of the functionality of the network device in this application may also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (e.g. a cloud platform).

The type of terminal device is not limited here either. By way of example, the terminal device may be a combination of one or more of a mobile phone (mobile phone), a tablet (pad), a computer with wireless transceiving functionality, a Virtual Reality (VR) terminal, an augmented reality (augmented reality, AR) terminal, a wireless terminal in an industrial control (industrial control), a wireless terminal in a self driving (self driving), a wireless terminal in a telemedicine (remote media), a wireless terminal in a smart grid (smart grid), a wireless terminal in a transportation security (transportation safety), a wireless terminal in a smart city (smart city), a wireless terminal in a smart home (smart home), a wireless terminal in an internet of things (internet of things, ioT), a wearable device, etc.

The terminal device may comprise a chip, which may include one or more processors, where the one or more processors may be coupled to a memory, and the memory may store instructions that, when executed by the one or more processors, may implement the functions involved in the terminal device in the embodiments of the present application. The specific structure of the chip and the type of processor included may vary and are not limited in this regard.

Fig. 1 shows an exemplary schematic diagram of a wireless communication system.

In the example shown in fig. 1, the base station may be in bi-directional communication connection with terminal devices such as cell phones, notebook computers, and smart glasses.

In a two-way communication scenario between a network device and a terminal device, communication between the network device and the terminal device may be performed through a downlink channel and an uplink channel. Wherein the downlink channel and the uplink channel may each comprise one or more unidirectional channels.

The downlink channels may include one or more of a physical downlink shared channel (physical downlink shared channel, PDSCH) and a physical downlink control channel (physical downlink control channel, PDCCH). The uplink channels may include one or more of a physical uplink control channel (physical uplink control channel, PUCCH), a physical random access channel (physical random access channel, PRACH), and a physical uplink shared channel (physical uplink shared channel, PUSCH). Of course, in other examples, the downlink channel and the uplink channel may also include other channels, which are not limited in this embodiment of the present application.

In various terminal devices such as smart phones and smart glasses, various multimedia services may be provided to users through wireless communication technologies such as 5G.

For example, at present, extended reality (XR) such as Virtual Reality (VR) and augmented reality (augmented reality, AR), real-time video transmission, cloud Gaming (CG), and other multimedia services with strong real-time and large data volume are being applied and developed in various terminal devices.

In order to continuously and stably provide services for users in a long duration, the problem of power consumption of terminal equipment is increasingly emphasized.

In wireless communication systems such as new air interface systems, discontinuous reception (discontinuous reception, DRX) techniques may be employed to reduce power consumption of terminal devices.

In the DRX mode, a DRX cycle (DRX cycle) is configured in the terminal device. As shown in fig. 2, an "On Duration" period and an "Opportunity for DRX" period are included in one DRX cycle. In the On Duration period, the terminal equipment is in an active state, and at the moment, the terminal equipment monitors the PDCCH to receive downlink information sent by network equipment such as a base station and the like through the PDCCH; in the period of Opportunity for DRX, the terminal device has an opportunity to enter a dormant state, and the terminal device does not monitor the PDCCH in the dormant state, so that the power consumption of the terminal device is saved. In the DRX mode, the terminal device entering the sleep state indicates that the terminal device does not monitor the PDCCH, but based on actual needs, the terminal device may still perform information interaction through other channels. For example, the terminal device in the sleep state may transmit uplink information to the network device through PUCCH, PUSCH, or the like, or receive downlink information transmitted by the network device through PDSCH, or the like.

A plurality of DRX cycles may be configured in the terminal device, for example, a long DRX-Cycle and a short DRX-Cycle may be configured, wherein the DRX cycles (e.g., long DRX Cycle and short DRX Cycle) in the terminal device may be configured by the base station through radio resource control (Radio Resource Control, RRC) signaling. The parameters involved in DRX include, but are not limited to, one or more of the following:

DRX long cycle (DRX-LongCycle), DRX short cycle (DRX-ShortCycle), DRX short cycle timer (DRX active duration timer), DRX start offset (DRX start offset), DRX slot offset (DRX-SlotOffset).

Wherein, DRX-LongCycle represents a period value of the long DRX cycle, DRX-StartOffset represents an offset of the long DRX cycle, and DRX-LongCycle and DRX-StartOffset together determine a starting subframe of the long DRX cycle. The DRX-short cycle represents a cycle value of a short DRX cycle, and the DRX-short cycle timer is used to configure the number of short DRX cycles. The drx-onduration timer is used for configuring the Duration of the On Duration period, and the drx-SlotOffset is used for configuring the delay of the drx-onduration timer start. Specifically, in one DRC period, the drx-onduration timer starts at the drx-SlotOffset time after the start of the On Duration subframe, where drx-SlotOffset is the offset in the On Duration subframe, and drx-SlotOffset is typically less than 1ms.

However, at present, techniques such as DRX are generally used to reduce power consumption of a terminal device in a downlink transmission scenario, but uplink transmission of the terminal device to a network device such as a base station is generally not affected by the techniques such as DRX.

The uplink transmission data in the terminal device, which is not affected by the DRX technology, may include, but is not limited to, one or more of the following data:

scheduling request (scheduling request, SR), channel state information (channel status information, CSI), sounding reference signal (sounding reference signal, SRs), hybrid automatic repeat request (hybrid automatic repeat request, HARQ) feedback information, link recovery request (link recovery request, LRR).

In practical applications, frequent uplink transmission may affect the sleep state of the terminal device, for example, when the terminal device needs to send information such as SR, CSI, SRS to the network device, the sleep state of the terminal device is often affected to increase power consumption of the terminal device, so that the endurance of the terminal device is affected, and it is difficult to ensure better user experience.

In the embodiment of the invention, the related uploading mechanism of the SR can be improved, and the related uploading mechanisms of the CSI and the SRS are improved, so that the information interaction frequency between the terminal equipment and the network equipment is reduced, the terminal equipment is not required to be in a state of high-power-consumption operation all the time due to frequent information interaction with the network equipment, and the power consumption of the terminal equipment is reduced.

The following describes, through various embodiments, a related upload mechanism of the SR and a related upload mechanism of the CSI and SRs, respectively. Wherein different embodiments may be combined with each other, and the same or similar parts between different embodiments may be referred to each other, which is not limited by the embodiments of the present application.

First, improvements to the relevant upload mechanism of the SR are introduced.

In the conventional art, regardless of whether the terminal device is in an active state or a sleep state, the terminal device may transmit an SR to a network device such as a base station when the SR is triggered. And after transmitting the SR, the terminal device needs to remain in an active state in order to be able to listen to the PDCCH until an uplink Grant (UL Grant) from the network device is obtained through the PDCCH in order for the terminal device to transmit a buffer status report (buffer size report, BSR).

Fig. 3 is a schematic diagram of a state change condition of a terminal device related to SR in the conventional technology.

In the example shown in fig. 3, during the "Opportunity for DRX" period, the terminal device may still transmit an SR to the base station while the terminal device is in a dormant state, and after transmitting the SR, the terminal device needs to remain in an active state in order to be able to listen to the PDCCH until an uplink grant from the network device is obtained through the PDCCH. As can be seen, the terminal device may need to be in a state of high power consumption operation all the time due to frequent transmission of information such as SR to the network device, and cannot enter the sleep state, resulting in an increase in power consumption of the terminal device.

By the embodiment of the application, the related uploading mechanism of the SR can be improved, so that the information interaction frequency between the terminal equipment and the network equipment is reduced, the terminal equipment is not required to be in a state of high-power-consumption operation all the time due to frequent information interaction, and the power consumption of the terminal equipment is reduced.

Specifically, the embodiment of the application provides an information processing method. The information transmission method relates to the terminal device and the network device in the wireless communication system.

As shown in fig. 4, the information transmission method includes steps 401 to 403.

In step 401, when the SR is triggered, the terminal device determines whether a time interval between a first time domain position corresponding to the SR and a second time domain position corresponding to the physical uplink channel meets a first preset condition.

In the embodiments and the interaction diagrams in the application, the network device and the terminal device are taken as the execution main body of the interaction diagram to illustrate the corresponding method, but the application does not limit the execution main body of the information interaction. For example, the network device in fig. 4 may also be a chip, a chip system, or a processor that supports the network device to implement a corresponding method, or may be a logic module or software that can implement all or part of the functions of the network device; the terminal device in the figure may also be a chip, a chip system, or a processor supporting the terminal device to implement the corresponding method, or may also be a logic module or software capable of implementing all or part of the functions of the terminal device.

In the embodiment of the present application, the condition that the SR is triggered is not limited herein. For example, in the case where the terminal device determines that there is uplink information to be transmitted without an uplink grant from the network device, the SR may be triggered to request uplink resources from the base station. Wherein, when there is data in the terminal device reaching the medium access control (media access control, MAC) layer, the terminal device determines that there is uplink information to be transmitted. Alternatively, the terminal device may trigger the SR with a specified period, where the trigger period corresponding to the SR is configured by the network device; at this time, even if no uplink data needs to be transmitted in the terminal device, the SR is triggered according to the specified period.

The first time domain position corresponding to the SR may be determined based on information such as a period of the uplink resource corresponding to the preconfigured SR. For example, the base station configures the terminal device with uplink resources for uploading the SR in advance, and the uplink resources for uploading the SR may be periodic. If the SR in the terminal device is triggered in a certain period, after the SR is triggered, the time domain position of the uplink resource to be scheduled for uploading the SR is the first time domain position corresponding to the SR.

The physical uplink channel may be PUSCH or PUCCH. The physical uplink channel may be an uplink resource pre-configured in the terminal device.

The second time domain position corresponding to the physical uplink channel may be determined based on a relevant configuration of the physical uplink channel and/or relevant indication information of the base station.

For example, the physical uplink channel may be PUSCH, and the base station sends configuration information about PUSCH to the terminal device in advance to configure a period of PUSCH. Thus, when the SR is triggered, according to the PUSCH period configured by the base station, the time domain position of the PUSCH to be scheduled may be determined, where the time domain position may be considered as the second time domain position corresponding to the physical uplink channel in the embodiment of the present application.

As another example, the physical uplink channel may be PUCCH, and in this case, the second time domain position of the physical uplink channel may be indicated to the terminal device by the base station through downlink control information (downlink control information, DCI), or may be configured by the base station to the terminal device through advanced signaling such as radio resource control (radio resource control, RRC) signaling.

In this embodiment, when the SR is triggered, the terminal device determines whether a time interval between a first time domain position corresponding to the SR and a second time domain position corresponding to the physical uplink channel meets a first preset condition.

The first preset condition may indicate that the time interval between the first time domain position and the second time domain position is relatively close.

For example, in some embodiments, the first preset condition is that a time interval between the first time domain position and the second time domain position is less than or equal to a first preset duration.

In the embodiment of the present application, the sequence between the first time domain position and the second time domain position is not limited. The second time domain position may be subsequent to the first time domain position or may be prior to the first time domain position.

The first preset duration may be described by the number of slots (slots), or may have other duration description manners. The specific value of the first preset duration is not limited herein. The first preset duration may be, for example, a duration between 1slot and 20 slots.

In this way, if the terminal device or the chip of the terminal device determines that the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel meets the first preset condition, uplink information may be sent to the network device through the physical uplink channel.

At this time, compared with the conventional technology, in the embodiment of the present application, the longest time delay that may be caused by transmitting the uplink information through the physical uplink channel does not exceed the first preset duration. Therefore, by reasonably setting the first preset duration, the terminal equipment can send the uplink information to the network equipment through the physical uplink channel under the condition that the time delay of the uplink information is kept within an acceptable range, so that the uplink information can be timely processed, and meanwhile, the interaction frequency between the terminal equipment and the network equipment can be reduced, so that the terminal equipment does not need to be kept in a state of high-power-consumption operation all the time due to the information interaction requirement, and the power consumption of the terminal equipment is reduced.

The first preset duration may be configured by the terminal device based on configuration information sent by the base station.

In some embodiments, the method further comprises steps 404-406 as in FIG. 4:

step 404, the network device sends configuration information to the terminal device;

step 405, the terminal device receives configuration information from the network device;

step 406, the terminal device determines a first preset duration according to the configuration information.

The type of configuration information is not limited herein. The configuration information may be DRX configuration information or SR configuration information, for example. The configuration information may include information of a first preset duration.

In the embodiment of the present application, the timing at which the network device sends the configuration information to the terminal device is not limited herein. For example, when the network device establishes a connection with the terminal device, the network device may send initial configuration information to the terminal device, where the initial configuration information may include information of an initial first preset duration. After receiving the initial configuration information, the terminal device may determine an initial first preset duration according to the initial configuration information. The terminal device may then perform step 401 and subsequent other related steps based on the initial first preset duration.

In addition, after the network device establishes connection with the terminal device and transmits the initial configuration information, the network device may update the first preset duration according to the change conditions of the device resource, the communication resource, and the like, and send the updated configuration information to the terminal device, so that the terminal device updates the first preset duration according to the updated configuration information. The terminal device may then perform step 401 and subsequent other related steps based on the updated first preset duration.

The first preset duration may be a fixed duration preconfigured by the network device; alternatively, the network device may determine, based on the current network situation, the device situation, or the like, from a plurality of candidate durations that are configured in advance.

In step 402, when the SR is triggered, the terminal device sends uplink information to the network device through the physical uplink channel if the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel satisfies the first preset condition.

The uplink information is an SR or a buffer status report BSR corresponding to the SR.

In this embodiment, after the terminal device determines the first preset duration, when the SR is triggered, the uplink information is sent to the network device through the physical uplink channel under the condition that a time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel meets the first preset condition.

The uplink information may be an SR or a BSR corresponding to the SR. For example, when the physical uplink channel is PUSCH, since PUSCH may be used for the terminal device to transmit data information and control information to the network device, at this time, the terminal device may send a BSR to the network device through PUSCH, and may directly transmit the BSR corresponding to the SR through PUSCH without sending the SR to the network device to request uplink resources. Or when the physical uplink channel is the PUCCH, since the PUCCH may be used for the terminal device to transmit control information to the network device, at this time, the terminal device may send an SR to the network device through the PUCCH without sending the SR through an uplink resource corresponding to the first time domain location, and send information corresponding to the second time domain location (such as HARQ feedback information, CSI or LRR) through the PUCCH corresponding to the second time domain location.

It should be noted that, in the embodiment of the present application, the information that the terminal device sends to the network device through the physical uplink information includes, but is not limited to, the uplink information. For example, when the physical uplink channel is PUSCH, the terminal device may send data information and a BSR corresponding to the SR to the network device through PUSCH; and when the physical uplink information is PUCCH, the terminal equipment can send SR, HARQ feedback information, CSI or LRR and the like to the network equipment through the PUCCH.

In step 403, the network device receives uplink information from the terminal device through the physical uplink channel.

In this embodiment, the uplink resource of the terminal device is generally allocated to the network device by the network device, so that the network device may determine a first time domain position corresponding to the uplink information and a second time domain position determined by the physical uplink channel, so as to determine that a time interval between the first time domain position corresponding to the uplink information and the second time domain position corresponding to the physical uplink channel meets a first preset condition.

In this embodiment of the present application, the network device receives uplink information from the terminal device through the physical uplink channel, and does not need to receive the SR through the uplink resource corresponding to the first time domain location, and receives information corresponding to the second time domain location through the physical uplink channel corresponding to the second time domain location (for example, if the physical uplink channel is PUCCH, the information corresponding to the second time domain location is HARQ feedback information, CSI or LRR, and if the physical uplink channel is PUSCH, the information corresponding to the second time domain location is data information). Therefore, through the embodiment of the application, the frequency of sending information to the network equipment by the terminal equipment can be reduced, so that the terminal equipment does not need to be always kept in a state of high-power-consumption operation due to frequent information interaction requirements, and the power consumption of the terminal equipment is reduced.

In the information transmission method, for different scenarios, the physical uplink channel may be PUSCH or PUCCH.

The following describes exemplary scenarios related to different types of physical uplink channels, respectively.

1. The physical uplink channel is PUSCH.

The PUSCH may be used for the terminal device to transmit data information and control information to the network device. Based on this, in the embodiment of the present application, under the condition that the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel meets the first preset condition, the SR need not be sent to the network device to request uplink resources, but the BSR corresponding to the SR may be directly transmitted through the PUSCH, so the number of information interaction between the terminal device and the network device is reduced, and the terminal device does not need to monitor the PDCCH for receiving the uplink grant corresponding to the SR, which avoids the high power consumption state of the terminal device after the SR is sent to the network device in the conventional technology, and reduces the power consumption of the terminal device.

In some embodiments, the physical uplink shared channel PUSCH is a Configured Grant (CG) PUCCH (CG PUSCH).

CG PUSCH is a pre-configured uplink resource for a base station. In practical application, network devices such as a base station can allocate uplink scheduling resources to terminal devices once through RRC signaling or through DCI carried by PDCCH, and then the terminal devices can periodically and repeatedly use the same uplink scheduling resources to perform uplink transmission, where the uplink scheduling resources are CG PUSCH.

As can be seen, after configuring the CG PUSCH, when the terminal device performs uplink information transmission through the CG PUSCH, the network device is generally not required to send the PDCCH for authorization. And when the terminal equipment is in a dormant state, the terminal equipment can still normally transmit uplink information through the CG PUSCH.

In this way, in the embodiment of the present application, uplink information may be sent to the network device through the CG PUSCH without the terminal device requesting other uplink resources for sending the BSR corresponding to the SR, and compared with the conventional technology, the terminal device does not need to transmit the SR, so that it is not necessary to be in an active state to monitor the PDCCH after sending the SR to the network device to obtain uplink authorization, thereby reducing power consumption of the terminal device.

In some embodiments, the physical uplink channel is a physical uplink shared channel, PUSCH;

the method further comprises the steps of:

and sending the data information to the network equipment through the PUSCH.

The data information does not include control signaling, unlike the control information. The terminal device typically transmits data information to the network device through a PUSCH, which may be an uplink resource for the data information that is pre-allocated to the terminal device by the network device.

In this embodiment of the present application, when a time interval between a first time domain position corresponding to an SR and a second time domain position corresponding to a physical uplink channel meets a first preset condition, data information and a BSR may be transmitted through a PUSCH. Wherein, the data information and the BSR can be multiplexed on the PUSCH for transmission. In the embodiment of the present application, the multiplexing technology adopted to multiplex the data information and the BSR on the PUSCH for transmission is not limited herein.

Illustratively, the multiplexing technique may be frequency division multiplexing (frequency division multiplexing, FDM), time division multiplexing (time division multiplexing, TDM), or code division multiplexing (code division multiplexing, CDM). In the practical application process, the terminal device may aggregate the data information and the BSR through a multiplexing technology (for example, aggregate the data information and the BSR through a multiplexer) and transmit the data information and the BSR through a PUSCH, and the network device may separate the data information and the BSR from the aggregated information through a demultiplexer or the like after receiving the aggregated information through the PUSCH to perform subsequent related operations.

The specific manner in which the data information and BSR are multiplexed on the PUSCH is not limited herein.

For example, the data information is a sub-protocol data unit (sub protocol data unit, sub-PDU) of the medium access control (medium access control, MAC) layer, and the BSR is a MAC Control Element (CE) and is also a separate MAC sub-PDU. When the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the PUSCH meets a first preset condition, the data information and the MAC sub PDU corresponding to the BSR respectively form one MAC PDU. The MAC PDU is transmitted to the network device through PUSCH at the physical layer.

According to the embodiment of the application, the data information and the BSR corresponding to the SR can be aggregated and transmitted, so that the transmission efficiency is improved; in addition, in the embodiment of the application, the interactive processes of sending SR to the network equipment by the terminal equipment, receiving uplink authorization from the network equipment by the terminal equipment and the like are canceled, and the information interactive frequency is reduced; and the terminal equipment does not need to be kept in an activated state after sending the SR to the network equipment so as to monitor the uplink authorization from the network equipment, thereby greatly reducing the power consumption of the terminal equipment.

For example, as shown in fig. 5a, an exemplary schematic diagram of the information transmission procedure related to SR and PUSCH in the conventional technology is shown.

In the conventional technology, after the SR is triggered, the terminal device sends the SR to the network device through an uplink resource for transmitting the SR. After transmitting the SR, the terminal device needs to remain in an active state to receive an uplink grant of the network device to transmit the BSR to the network device through the uplink grant. In addition, data information is transmitted to the network equipment through the PUSCH.

In an example of the embodiment of the present application, a schematic diagram of information transmission corresponding to the terminal device is shown in fig. 5 b.

When the time interval between the first time domain position and the second time domain position corresponding to the SR is smaller than the first preset condition, the terminal device may cancel sending the SR, and multiplex the BSR corresponding to the SR and the data information on the PUSCH for transmission. Compared with the flow shown in fig. 5a, in the interaction flow in fig. 5b, the interaction processes of the terminal device sending SR to the network device, the terminal device receiving uplink authorization from the network device, and the like are cancelled, so that the information interaction frequency is reduced; and the terminal equipment does not need to be kept in an activated state after sending the SR to the network equipment so as to monitor the uplink authorization from the network equipment, thereby greatly reducing the power consumption of the terminal equipment.

When the physical uplink channel is PUSCH, in some examples, the terminal device may set a state corresponding to the SR to a pending (pending) state when the SR is triggered. And canceling the pending state corresponding to the SR when it is determined that the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel satisfies the first preset condition, or canceling the pending state corresponding to the SR at a time (for example, at a time when uplink information is transmitted to the network device) after it is determined that the time interval between the first time domain position and the second time domain position satisfies the first preset condition.

Alternatively, in other examples, since the SR need not be sent to the network device, the state change corresponding to the SR may not be recorded, that is, the state corresponding to the SR need not be set to the pending state when the SR is triggered.

2. The physical uplink channel is PUCCH.

The PUCCH may be used for the terminal device to transmit control information to the network device. Based on this, in the embodiment of the present application, when the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel meets the first preset condition, the terminal device can effectively use the existing uplink resource PUCCH to transmit the SR, and does not schedule other uplink resources (for example, uplink resources corresponding to the first time domain position) for transmitting the SR, thereby reducing the number of information interaction between the terminal device and the network device and reducing the power consumption of the terminal device.

In some embodiments, the physical uplink channel is a physical uplink control channel, PUCCH;

the method further comprises the steps of:

transmitting at least one of the following information to the network device through the PUCCH:

HARQ feedback information, CSI, LRR.

In this embodiment of the present application, the PUCCH may be an uplink resource that is pre-allocated to the terminal by the network device, and the uplink resource may transmit at least one of HARQ feedback information, CSI, and LRR.

In the embodiment of the present application, for convenience of description, at least one of HARQ feedback information, CSI, LRR is referred to as designated control information, where the designated control information does not include SR.

In this embodiment of the present application, when a time interval between a first time domain position corresponding to an SR and a second time domain position corresponding to a PUCCH satisfies a first preset condition, the SR and the designated control information may be transmitted through the PUCCH.

Wherein the SR and the designated control information may be multiplexed on the PUCCH for transmission. In the embodiment of the present application, the multiplexing technology adopted to multiplex SR and the specified control information on PUCCH for transmission is not limited herein.

The specific manner in which the SR and the designated control information are multiplexed on the PUCCH is not limited herein.

For example, when the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the PUCCH satisfies the first preset condition, the terminal device determines the cyclic shift offset m corresponding to the PUCCH by querying the correlation list according to the SR and the specified control information _CS . The terminal device transmits the PUCCH to the network device. Thus, after receiving the PUCCH, the network device receives the corresponding m according to the PUCCH _CS The SR and the specified control information are determined by querying a correlation list or the like.

By the embodiment of the application, the SR, the HARQ feedback information, the CSI, the LRR and other appointed control information can be transmitted in an aggregation mode, so that the transmission efficiency is improved, the information interaction frequency is reduced, and the power consumption of the terminal equipment is reduced.

For example, in an exemplary information transmission diagram corresponding to the terminal device shown in fig. 6a, an information transmission flow related to SR and PUCCH in the conventional technology is shown.

In the conventional technology, after the SR is triggered, the terminal device sends the SR to the network device through an uplink resource for transmitting the SR. In addition, HARQ feedback information or CSI is transmitted to the network equipment through the PUCCH.

In an example of the embodiment of the present application, a schematic diagram of information transmission corresponding to the terminal device is shown in fig. 6 b.

When the time interval between the first time domain position and the second time domain position corresponding to the SR is smaller than a first preset condition, the terminal device may multiplex the SR and the data information on the PUSCH for transmission. Compared with the flow shown in fig. 6a, in the interaction flow in fig. 6b, the interaction process that the terminal device independently transmits the SR through the uplink resource is cancelled, so that the information interaction frequency is reduced, and the power consumption of the terminal device is also reduced.

In addition, in some embodiments of the information processing method, the terminal device is in a dormant state in which it does not monitor the physical downlink control channel PDCCH.

The sleep state may be a sleep state of the terminal device in the DRX mode. In the DRX mode, the terminal device does not monitor the PDCCH while in the sleep state. Alternatively, the sleep state refers to a PDCCH skip (PDCCH skip) state. And when the terminal equipment is in the PDCCH skip state, the PDCCH is not monitored.

The sleep state in the embodiment of the present application is for monitoring PDCCH, which means that the terminal device does not monitor PDCCH, but in some examples, the terminal device may still perform information interaction through other channels. For example, the terminal device in the sleep state may transmit uplink information to the network device through PUCCH, PUSCH, or the like, or receive downlink information transmitted by the network device through PDSCH, or the like.

In the embodiment of the present application, step 402 may be performed when the terminal device is in the sleep state. That is, when the terminal device is in the sleep state: when the SR is triggered, the terminal equipment sends uplink information to the network equipment through the physical uplink channel under the condition that the time interval between the first time domain position corresponding to the SR and the second time domain position corresponding to the physical uplink channel meets a first preset condition.

At present, when the terminal equipment is in a dormant state of not monitoring the physical downlink control channel PDCCH, if the terminal equipment frequently transmits data to the network equipment, the dormant state of the terminal equipment is interrupted, so that the power consumption of the terminal equipment is increased.

For example, when the terminal device is in a sleep state in the DRX mode, the UE may only enter a microsleep (microsleep) state when the sleep time of the terminal device is less than 6 ms; when the sleep time is greater than or equal to 6 milliseconds, the terminal device may enter a light sleep (light sleep) state. In the light sleep state, the power consumption of the terminal device is lower than that in the micro sleep state, and the power consumption is saved.

However, in an exemplary state change diagram of the terminal device shown in fig. 7a, uplink transmission of information such as SR, HARQ feedback information, CSI, etc. in the terminal device is not affected by the sleep state of the terminal device, so the terminal device may frequently send information such as SR, HARQ feedback information, CSI, etc. to the network device during the period of time when the terminal device is in the sleep state, and the time interval between these uplink transmission operations is less than 6 ms, which results in that the terminal device is in the micro sleep state in multiple stages, compared with the light sleep state.

In an example of the embodiment of the present application, as shown in fig. 7b, if the time interval between the first time domain position corresponding to the SR and the second time domain position of the PUCCH corresponding to the CSI meets the first preset condition, the CSI and the SR may be multiplexed and then sent to the network device through the PUCCH, so that the number of uplink transmissions performed by the terminal device in the dormant state is reduced, so that the terminal device may maintain the light sleep state with smaller power consumption in a longer period of time in the dormant state, and the power consumption of the terminal device is obviously saved.

As can be seen, in the embodiment of the present application, when the terminal device is in a dormant state where the physical downlink control channel PDCCH is not monitored, the steps 401 to 403 are executed, so that the number of times that the terminal device performs uplink transmission in the dormant state can be reduced, so that the terminal device can maintain a light sleep state with smaller power consumption in a longer period of time in the dormant state, and the power consumption of the terminal device is obviously saved.

The following describes an information transmission method to improve a relevant uploading mechanism of CSI and/or SRS, so as to reduce the information interaction frequency related to CSI and/or SRS between a terminal device and a network device, so that the terminal device does not need to be in a state of high power consumption operation all the time due to the information interaction related to CSI and/or SRS, and power consumption of the terminal device is reduced.

As shown in fig. 8, the information transmission method may include steps 801-803.

In step 801, the network device sends indication information to the terminal device.

The indication information is used for indicating the terminal equipment to send the CSI or the SRS.

In some examples, the CSI may be aperiodic CSI (a-CSI). Currently, in a terminal device, uplink transmission of aperiodic CSI and SRS is generally not limited by a dormant state of the terminal device, and after the terminal device receives DCI from a network device indicating to send aperiodic CSI or SRS, even if the terminal device is in the dormant state, the terminal device sends aperiodic CSI or SRS to the network device.

The indication information may be DCI, for example. The network device may generate DCI based on actual scenario requirements of a communication situation, a device situation, etc. to instruct the terminal device to send CSI or SRS to the network device.

Step 802, when the terminal device receives the indication information from the network device, it is determined whether the time interval between the third time domain position corresponding to the CSI or SRS and the fourth time domain position corresponding to the physical uplink channel meets a second preset condition.

In step 803, when the terminal device receives the indication information from the network device, if the time interval between the third time domain position corresponding to the CSI or SRS and the fourth time domain position corresponding to the physical uplink channel meets the second preset condition, the terminal device sends the CSI or SRS to the network device through the physical uplink channel.

In step 804, the network device receives CSI or SRS through a physical uplink channel.

In the conventional technology at present, the uplink transmission of CSI or SRS in the terminal device is often not affected by the state of the terminal device. For example, when the terminal device is in the sleep state in the DRX mode, the terminal device may still be triggered to send the aperiodic CSI or SRS to the network device such as the base station, which may cause the terminal device to fail to maintain the sleep state with low power consumption, so that the power consumption of the terminal device increases.

In the embodiment of the present application, when the CSI or SRS is triggered, the terminal device sends the CSI or SRS to the network device through the physical uplink channel if the time interval between the third time domain position corresponding to the CSI or SRS and the fourth time domain position corresponding to the physical uplink channel meets the second preset condition. The physical uplink channel may be considered as an uplink resource obtained by the terminal device, so that the terminal device may send CSI or SRS through the obtained uplink resource, and no other uplink resource is needed to send CSI or SRS to the network device such as the base station, thereby reducing the interaction frequency between the terminal device and the network device such as the base station, and further reducing the power consumption of the terminal device.

In some embodiments, the second preset condition is that a time interval between the third time domain position and the fourth time domain position is less than or equal to the second preset time period.

In some embodiments, as shown in fig. 8, the method further comprises:

step 805, the network device sends configuration information to the terminal device;

step 806, the terminal device receives configuration information from the network device;

in step 807, the terminal device determines a second preset duration according to the configuration information.

In some embodiments, the terminal device is in a dormant state in which it does not monitor the physical downlink control channel PDCCH.

In some embodiments, the physical uplink channel is a physical uplink control channel PUCCH, and the indication information is used to instruct the terminal device to send CSI;

the method further comprises the steps of:

the terminal device sends at least one of the following information to the network device through the PUCCH:

HARQ feedback information, CSI, LRR;

HARQ feedback information, SR, LRR.

In some embodiments, the physical uplink channel is a physical uplink shared channel PUSCH;

the terminal equipment sends data information to the network equipment through the PUSCH;

The network device receives data information from the terminal device through the PUSCH.
