Description

Method and device for determining and configuring uplink resources

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for determining and configuring uplink resources.

Background

Currently, small Data Transmission (SDT) of a User Equipment (UE) is supported in an Radio Resource Control (RRC) inactive state. Specifically, small data transmission (RA-SDT) based on Random Access (RA) and SDT transmission (CG-SDT) based on configured uplink grant Configuration (CG) type1 (type 1) resources are supported.

For CG-SDT, a UE may obtain a configuration of multiple CG resources, and for a UE that needs to perform small data transmission, these resources are all available, so the UE may separately group data that needs to be transmitted in the multiple resources, however, the UE finally performs data transmission in only one of the resources, and performing group transmission in other resources than the resource may increase power consumption of the UE.

Disclosure of Invention

The application provides a method and a device for determining and configuring uplink resources, which are used for reducing the power consumption of UE (user equipment) in a small data transmission process.

In a first aspect, the present application provides a method for determining uplink resources, where the method may be performed by a terminal device. The terminal device may be a UE or a component in a UE.

The method comprises the following steps: the terminal device may receive configuration information of a first uplink resource, where the configuration information of the first uplink resource includes a plurality of uplink grant configurations of the first uplink resource. The terminal device may suspend one or more of the plurality of uplink grant configurations.

Based on the method, the terminal device can suspend the plurality of uplink grant configurations indicated by the configuration information after receiving the configuration information of the first uplink resource, so as to avoid that the UE performs data packet transmission on the resource corresponding to the suspended uplink grant configuration in the small data transmission process, and reduce the power consumption of the UE.

In a possible design, the configuration information of the first uplink resource is carried in a release message, and the terminal device may suspend all uplink grant configurations in response to the release message.

In one possible design, the terminal device may further determine a first resource in the first uplink resources, and recover the uplink grant configuration corresponding to the first resource, where the first resource is used for transmitting the first data.

In a possible design, the configuration information of the first uplink resource is carried in a release message, and the terminal device may determine a first resource in the first uplink resource, where the first resource is used for transmitting first data. The terminal device may suspend uplink grant configuration other than the uplink grant configuration corresponding to the first resource from the plurality of uplink grant configurations.

In a possible design, the terminal device may further receive feedback information of the first data, suspend the uplink grant configuration corresponding to the first resource, and/or initialize the uplink grant configuration corresponding to the first resource. By adopting the design, the terminal device can respond to the feedback information of the first data to suspend and/or initialize the uplink authorization configuration corresponding to the first resource after sending the first data, thereby avoiding the misalignment of the configuration between the UE and the base station.

In one possible design, the first data includes newly transmitted data and/or retransmitted data.

In a possible design, the terminal device may further determine that the timing advance TA is invalid, and suspend the uplink grant configuration corresponding to the first resource. By adopting the design, the first resource can be suspended when TA is invalid due to RSRP change and the like so as to improve the transmission quality, and if the TA is invalid, if the first resource is still adopted for transmission, the transmission can be subjected to stronger interference, so that the transmission quality is poor.

In one possible design, the terminal device may determine that the TA is invalid if it is determined that the TA timer times out and/or if it is determined that the amount of change in the TA exceeds a threshold.

In one possible design, the resource in the first uplink resource corresponds to the uplink grant configuration.

In one possible design, the terminal device may further initialize one or more of the plurality of uplink grant configurations to avoid misalignment of configurations between the UE and the base station. The UE and the network device may both initialize the same uplink grant configuration of the multiple uplink grant configurations, for example, both the UE and the network device initialize all uplink grant configurations indicated by the configuration information of the first uplink resource.

In a possible design, the uplink resource in the first uplink resource is associated with a synchronization signal and a physical broadcast channel block SSB, and the terminal device may further send the random access message when a received signal strength of the SSB associated with the uplink resource in the first uplink resource is less than or equal to a received signal strength threshold. Therefore, when the CG resources do not meet the condition, the uplink resources can be acquired again through the random access process, and the transmission efficiency is improved.

In one possible design, data corresponding to the first radio bearer may be carried in the random access message to further improve transmission efficiency.

In one possible design, if the terminal device is a UE, the RRC state of the terminal device is an RRC inactive state. If the terminal device is a component in the UE, the RRC state of the UE to which the terminal device belongs is an RRC inactive state, or the RRC state corresponding to the terminal device is an RRC inactive state.

In a second aspect, the present application provides a method for configuring uplink resources, where the method is executable by a network device. The network device is for example a base station or a component in a base station etc.

The method comprises the following steps: the network equipment sends configuration information of a first uplink resource, wherein the configuration information of the first uplink resource comprises a plurality of uplink authorization configurations of the first uplink resource. The network device may also initialize one or more of the plurality of uplink grant configurations to avoid misalignment of the UE with the network device configuration.

In a possible design, the network device may further send feedback information of first data, where the first data is carried in a first resource, and the first uplink resource includes the first resource, and initialize an uplink grant configuration corresponding to the first resource.

Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application provides a method and a device for determining and configuring uplink resources, which are used for reducing power consumption of UE (user equipment) in small data transmission. The method and the device are based on the same technical concept, and because the principle of solving the problems of the method and the device is similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.

In the description of the present application, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order.

It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.

In the present application, a network device supports communication with a terminal apparatus. Specifically, the network device may communicate with the UE through a universal user to network (Uu) interface, for example, configure uplink resources of the UE through the Uu interface.

The terminal equipment may also be referred to as User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (smart city), a smart wearable device (smart glasses, smart watch, smart headset, etc.), a wireless terminal in smart home (smart home), etc., and may also be a chip or a chip module (or a chip system) that can be provided in the above devices, etc. The embodiments of the present application do not limit the application scenarios.

It should be noted that the communication system shown in fig. 1 may be, but is not limited to, a fourth generation (4 th generation,4 g) system, a fifth generation (5 th generation,5 g) system, such as new radio access technology (NR), stand-alone networking (SA), and the like. Optionally, the method of the embodiment of the present application is also applicable to various future communication systems, such as a sixth generation (6 g) system or other communication networks.

It should be noted that the devices shown in fig. 1 are merely examples, and the communication system may also include other devices besides a network device and a terminal device, which is not limited in this application. The number of the network devices and the number of the terminal devices are also merely examples, and the number of the network devices and the number of the terminal devices in the communication system may be multiple, which is not limited in the present application.

In the following, a method embodiment provided in the embodiment of the present application is described by taking a network device as a base station and a terminal device as a UE as an example, which should not be construed as being implemented only by the base station and the UE.

The current 5G NR supports the UE to transmit data in an RRC inactive state (hereinafter, referred to as an inactive state) and an RRC connected state (hereinafter, referred to as a connected state). The procedure for small data transmission is shown in fig. 2, for example. In this application, the INACTIVE state is also called an RRC _ INACTIVE state, and is a state in which the UE remains in a connection management CONNECTED (CM-CONNECTED) state and can move within an area configured by the access network device without notifying the access network device, and in this state, the UE and the access network device store a UE context. The connected state refers to a state in which the UE having established the RRC connection is located. In addition, the RRC state may also include an RRC idle (idle) state (hereinafter, referred to as an idle state), which refers to an RRC state in which the UE is in a case where the UE does not establish an RRC connection.

In step 0 shown in fig. 2, the UE in the inactive state or the connected state receives an RRC release message containing the suspend configuration from the base station, and after receiving the RRC release message, the UE enters or remains in the inactive state. The RRC release message may further include CG configuration used by the UE in an inactive state for small data transmission, where the CG configuration includes time domain resource allocation information, frequency domain resource allocation information, physical layer configuration information, timer information, or a period used for uplink transmission. Based on the CG configuration, the UE may determine time-frequency resources for CG transmission. That is, it is understood that the CG configuration corresponds to an uplink grant resource, and can be used for transmitting an uplink message or uplink data. In this application, CG configuration configured or preconfigured by a message such as an RRC release message by a network device may be referred to as configured CG configuration, and may be referred to as CG configuration for short subsequently, and accordingly, a resource corresponding to CG configuration may be referred to as CG resource.

The RRC release message may include configuration information of one or more CG resources, where the configuration information of the CG resources may be configuration information of CG type1 resources. Through the configuration information of the CG resources, the configured uplink authorized resources can be determined, wherein each resource can be used for data transmission of CG-SDT.

After receiving the RRC release message, the UE is in an RRC inactive state.

When the UE satisfies the small data transmission condition and selects CG-based small data transmission based on the criteria of CG-SDT selection, the UE initiates a CG-SDT procedure.

Wherein, the UE satisfies the small data transmission condition, and all of the following conditions are to be satisfied:

1) The data amount of the data to be transmitted is less than the configured threshold. The data to be sent may be data buffered by the UE.

2) The Reference Signal Received Power (RSRP) is greater than the configured RSRP threshold.

3) All data to be transmitted is mapped to a Radio Bearer (RB) of the SDT, such as a Data Radio Bearer (DRB) or a signaling radio bearer (DRB). This RB may be subsequently referred to as an SDT RB. Wherein the radio bearer of the SDT may be network device configured or pre-configured or predefined.

Optionally, the UE satisfies the small data transmission condition, and further includes: either CG resources or RA resources for small data transmissions are available.

Step 1, the ue sends a first uplink message on the configured grant, where the uplink message is, for example, an RRC recovery request (resume request) message and first uplink data.

During the SDT process, the UE may select a synchronization signal and a Physical Broadcast Channel (PBCH) block (SSB) according to the configured RSRP threshold. For CG-SDT, the UE selects an SSB with SS-RSRP higher than the threshold, and selects a CG resource (or CG configuration) associated with the selected SSB for uplink data transmission, e.g., the UE may perform the sending of the first uplink message and the first uplink data in step 1 according to the CG resource.

Optionally, in step 1, the UE may also send UE auxiliary information, such as a Buffer Status Report (BSR) and/or Release Assistance Information (RAI).

Optionally, if the UE has data to send in addition to the first uplink data, the UE may also send UE auxiliary information in step 1, where the UE auxiliary information includes, for example, a Buffer Status Report (BSR) and/or Release Assistance Information (RAI).

And 2, after the UE sends the first uplink message, monitoring a Physical Downlink Control Channel (PDCCH).

After receiving the first uplink message sent by the UE, the base station sends feedback information corresponding to the first uplink message, where the feedback information may be a reception acknowledgement indicating that the base station receives the first uplink data, or a downlink message responding to the first uplink message, where the downlink message may be an RRC message and/or downlink data.

Step 3, if the UE also sends UE auxiliary information in step 1, the auxiliary information indicates to the base station that the UE has subsequent data to transmit, the base station may send scheduling information to the UE for scheduling grant resources for subsequent transmission in a dynamic scheduling manner. Or, the subsequent transmission may also be transmitted in a CG manner, that is, the uplink resource is still determined from the CG resource during the subsequent transmission.

In this application, the subsequent transmission includes segmenting the uplink data, and then transmitting the uplink data except the first uplink data. Or, the subsequent transmission includes that, in the data transmission of the current SDT, new data corresponding to the SDT RB arrives, and the newly arrived data may also be the subsequent transmission, for example, before the UE receives the next RRC release message after step 0, new SDT data needs to be transmitted, and the data is also considered to be the subsequent transmission. Alternatively, the subsequent transmission may comprise a transmission of retransmission data.

The dynamic scheduling refers to scheduling, by a base station, an uplink transmission grant of a UE through scheduling information such as Downlink Control Information (DCI), and the grant may be referred to as a dynamic scheduling grant (DG).

And 4, if the base station schedules the subsequent transmission of the UE in the step 3 in a dynamic scheduling mode, the UE performs uplink transmission of subsequent data according to the scheduling information in the step 3. Further, if there is no dynamic scheduling by the base station, the UE may make subsequent transmissions based on the CG resources, i.e., send the subsequent transmissions on the next available occasion in the CG resources.

Step 5, if the base station determines that the UE has no subsequent transmission, the base station may send an RRC release message to the UE, terminating the SDT procedure. Optionally, if the UE does not report the auxiliary information, or if the base station does not receive the auxiliary information sent by the UE, or the auxiliary information reported by the UE indicates that the UE has no subsequent data transmission, the base station may determine that there is no subsequent transmission.

It should be noted that, in the current SDT procedure, the UE may send multiple uplink and downlink data in one SDT procedure, and the UE does not need to switch to the connected state in this procedure.

Based on the small data transmission process in fig. 2, if the base station configures multiple CG configurations for SDT, the UE may group the data to be transmitted according to all CG resources after selecting to perform CG-SDT in the presence of small data to be transmitted. As described above, the UE selects the SSB based on the RSRP, determines the resource for uplink transmission based on the selected SSB, that is, determines the resource for uplink transmission from the CG resources, that is, determines the CG configuration for uplink transmission from the multiple CG configurations, and finally transmits the data to be transmitted according to the selected resource. However, before the CG resources for uplink transmission are selected, the UE may perform packet packing on the unselected CG resources, and since data is not transmitted on the unselected CG resources, in other words, data packed on the unselected CG resources is not finally transmitted, the process of performing packet packing on these CG resources may cause waste of power consumption of the UE.

In order to reduce power consumption caused by unnecessary group packaging of the UE in the SDT process, embodiments of the present application provide a resource determination and configuration method. The method may include the steps shown in fig. 3:

s101: the base station sends configuration information of the first uplink resource, wherein the configuration information of the first uplink resource comprises a plurality of uplink authorization configurations of the first uplink resource. In this application, the uplink grant configuration refers to a configured grant configuration, that is, a CG configuration.

In a possible implementation manner, the configuration information of the first uplink resource may further include only one uplink grant configuration. The first uplink resource is, for example, a CG resource, and the uplink grant configuration is, for example, a CG configuration, and optionally, the CG configuration may be a CG type1 or a CG type 2. It is to be understood that if the CG type is CG type1, the corresponding CG resource is a type1 resource, and if the CG type is CG type 2, the corresponding CG resource is a type 2 resource. That is, the uplink grant configuration indicated by the configuration information of the first uplink resource in the present application includes, but is not limited to, a CG configuration with a CG type being CG type1 and a CG configuration with a CG type being CG type 2.

In S101, the first uplink resource may include multiple uplink resources, and the uplink resources correspond to the uplink grant configuration. For example, one uplink resource corresponds to one uplink grant configuration. The uplink grant configuration may be configuration information of one CG, where the configuration information indicates a frequency domain, a period, and the like, and one CG resource may be determined according to the uplink grant configuration, where the one CG resource may correspond to multiple occasions of a CG uplink grant time-frequency resource.

Optionally, the resource in the first uplink resource may be associated with an SSB, and is used for the UE to determine a transmission resource of data from the resource included in the first uplink resource according to the SSB. Specifically, the UE determines a relationship between the SS-RSRP measured by the UE and the RSRP threshold based on the configured RSRP threshold, and the UE may select an SSB having an SS-RSRP greater than the RSRP threshold, and select a CG resource associated with the SSB, where the CG resource is a transmission resource of data.

Accordingly, the UE receives configuration information of the first uplink resource.

Optionally, after sending the configuration information of the first uplink resource, the base station may initialize one or more of the multiple uplink grant configurations. When the upper layer configures the CG configuration for the serving cell, a Media Access Control (MAC) entity of the UE stores an uplink grant provided by the upper layer of the MAC entity as a configured uplink grant for the serving cell, and initializes or re-initializes the configured uplink grant configuration, which can avoid misalignment between the UE and the base station.

The configuration information of the first uplink resource may be carried in the RRC release message, and the configuration information of the first uplink resource is included in the RRC release message. The RRC release message may refer to the description in step 0 shown in fig. 2.

S102: the UE suspends (suspend) one or more of the plurality of uplink grant configurations.

The suspension means that the uplink grant configuration is set to be temporarily unused. It is further understood that the UE maintains the configuration information of the uplink grant configuration, but the configuration is in a deactivated state. In the present application, the UE does not perform data packet packing according to the resource corresponding to the pending uplink grant configuration.

According to the method, after receiving the configuration information of the first uplink resource, the terminal device suspends one or more uplink grant configurations indicated by the configuration information, so that the UE is prevented from performing data packet transmission on resources corresponding to the suspended uplink grant configurations in the small data transmission process, and the power consumption of the UE can be reduced.

Further, in addition to suspending one or more of the plurality of uplink grant configurations, the UE may initialize one or more of the plurality of uplink grant configurations. The uplink grant configuration suspended by the UE and the uplink grant configuration initialized or reinitialized by the UE may be the same or different. The initialization can avoid misalignment between the UE and the base station.

A manner in which the UE suspends one or more of the plurality of uplink grant configurations in S102 is described below.

In the mode 1, the UE can suspend all uplink grant configuration and recover part of the uplink grant configuration before uplink data transmission, so as to perform data transmission according to resources corresponding to the recovered uplink grant configuration. In this application, resuming refers to setting the state of the suspended uplink grant configuration to be available.

Specifically, if the uplink grant configuration is carried in the RRC release message, the UE may suspend all uplink grant configurations in response to the RRC release message. It should be understood that all uplink grant configurations may also be replaced with any (any) uplink grant configuration. And then the UE can determine a first resource for data transmission and recover the uplink grant configuration corresponding to the first resource. The first resource may be one of first uplink resources, and the first resource may be used for the UE to transmit first data in a CG-SDT procedure. Optionally, the first resource may also be multiple resources in the first uplink resource, and the first resource may be used for the UE to send uplink data in the CG-SDT process.

In the method 2, before uplink data needs to be sent, the ue may determine a first resource from resources included in the first uplink resource, and suspend uplink grant configurations other than the uplink grant configuration corresponding to the first resource in the plurality of uplink grant configurations.

Specifically, after receiving the configuration information of the first uplink resource, the UE may initialize all uplink grant configurations included in the configuration information. When small data transmission is needed, the UE may determine the first resource from the resources included in the first uplink resource, and suspend other uplink grant configurations except the uplink grant configuration corresponding to the first resource, so as to avoid grouping the resources corresponding to the suspended uplink grant configurations, thereby saving power consumption. The UE may also transmit first data over the first resource.

It should be understood that the first resource in the above manner 1 and manner 2 may include one or more resources available for uplink transmission. The first data transmitted by the first resource may be data corresponding to a first radio bearer, where the first radio bearer may be a radio bearer used for small data transmission, or the first data may be data in small data transmission. The first data may be newly transmitted or retransmitted data. The new transmission refers to data transmitted for the first time or the first time, and the retransmission refers to data which has been transmitted before but is retransmitted due to unsuccessful transmission.

Optionally, the first resource in the above mode 1 and mode 2 may also be used for sending an RRC message and/or UE assistance information. RRC messages, e.g., RRC resume request messages, UE assistance information, e.g., BSR and/or RAI.

In the above mode 1 and mode 2, the UE may select the SSB according to the RSRP and recover the first resource corresponding to the selected SSB, where the process of selecting the SSB by the UE may refer to the process of selecting the SSB by the UE in the flow illustrated in fig. 2, which is not limited in this application. For example, the UE may select the SSB from among at least one SSB having an RSRP not less than an RSRP threshold, and use resources associated with the SSB for data transmission.

Further, if the UE determines that RSRPs of all SSBs of the first resource association are less than the RSRP threshold, the UE may initiate a random access procedure. Optionally, the uplink data may be transmitted through an uplink grant obtained in the random access process. For example, when determining that RSRPs of all SSBs associated with the first resource are smaller than the RSRP threshold, the UE sends a random access request to the base station, that is, the UE initiates a random access procedure. Optionally, the random access request may carry data that the UE needs to send. If the UE has small data to send and the size of the data is larger than the size of the grant allocated in the Random Access Response (RAR) message 2, the UE may segment the data and may carry the first segmented data packet in the random access request. Illustratively, the random access request may be message 3 (Msg 3) in a 4-step random access procedure.

In the above mode 1 and mode 2, after the UE determines the first resource, if the RSRP changes, which results in that the Timing Advance (TA) of the UE is invalid, the UE suspends the previously determined first resource. The reason why the TA is invalid may be that the UE determines that a TA timer expires, where the TA timer is used to determine that the current TA is valid, and the TA timer is a configured value, and if the UE does not receive a TA command from the network before the TA timer expires, the TA timer will run until the TA timer expires. The TA command is used for TA update and restarting the timer, that is, if the UE receives the TA command, the TA is updated; and if the UE receives the TA command before the TA timer is overtime, the UE restarts the TA timer. Alternatively, the reason for TA inactivity may be that the UE determines that the change (or amount, magnitude of change) in TA exceeds a threshold, where the change in TA corresponds to a change in RSRP of the serving cell. Wherein the increase in RSRP of the serving cell RSRP does not exceed (or reach) threshold 1 since the last TA verification, which threshold 1 may be an RSRP-inclusive thresh, and the decrease in RSRP of the serving cell RSRP does not exceed (or reach) threshold 2 since the last TA verification, which threshold 2 may be an RSRP-decreased threshold (e.g., RSRP-decreasthresh), which is not a change in TA that does not exceed the threshold.

In one possible implementation, if the UE determines that the TA is invalid, the UE initiates a random access procedure and reacquires the TA. After the TA is regained, the UE may still use the former CG configuration for small data transmission.

In this application, the base station may further indicate to the UE, or define or implement the decision by the UE through a pre-configured manner or by a protocol, and define that the first resource is only used for the new transmission, or is used for both the new transmission and the retransmission.

The UE may transmit first data through the first resource and receive feedback information for the first data from the base station.

If the first resource can only be used for new transmission, the UE may suspend and/or reconfigure the uplink grant configuration corresponding to the first resource in response to the feedback information, which may be used to determine whether the base station successfully receives the first data. Optionally, in this application, the base station may receive the first data from the UE through the first resource, and initialize the uplink authorization information corresponding to the first resource after sending the feedback information of the first data.

If the subsequent transmission needs to be sent, the UE may be required to re-determine the resource for transmitting the data by means of the above manner 1 or manner 2, where the re-determined resource may be the first resource or another resource other than the first resource. Alternatively, the base station may dynamically schedule resources for subsequent transmission or transmission of newly transmitted data, for example, as shown in step 3 in fig. 2. Subsequent transmissions herein include, but are not limited to, retransmission data for the first data. Wherein, if the subsequent transmission needs to be sent, the UE may send the assistance information to the base station to indicate that the subsequent transmission exists, otherwise, if the base station does not receive the assistance information, it is determined that the UE does not have the subsequent transmission.

If the first resource can be used for both new transmission and retransmission, after the first data is sent, if the UE needs to send subsequent transmission or retransmission data of the first data, the UE can still send data through the first resource without reselecting the resource.

Optionally, if the base station decides to release the UE to the inactive state, the base station may send an RRC release message including the suspension configuration to the UE, and the UE may suspend and/or initialize all (or any) uplink grant configurations according to the RRC release message. Optionally, the RRC release message may also reconfigure the CG configuration for the next SDT transmission, for example, see the reconfigured CG configuration. The UE may remain in the RRC inactive state at this time.

In addition, if the base station decides to release the UE to the idle state, the base station may send an RRC release message not including the suspend configuration to the UE, and the UE may release to the RRC idle state after receiving the RRC release message.
