Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an inactivity timer control method and apparatus for DRX, a storage medium, a terminal, and a base station.
Background
In a wireless communication network, since a terminal device (also referred to as a User Equipment, UE for short) usually uses a battery, in order to prolong the service life of the battery and avoid frequent battery replacement or charging, a Discontinuous Reception (DRX) mechanism is introduced for the purpose of saving energy. When the terminal device is configured with DRX, the terminal device monitors Control information from the network device only under a specific condition or in a specific time period, for example, control information carried on a Physical Downlink Control Channel (PDCCH for short), where the Control information includes Control information for scheduling uplink and Downlink resources and also includes Control information for adjusting the transmission power of the terminal device, for example. Since the terminal device does not need to detect the control information every moment, energy consumption can be reduced.
Under the DRX mechanism, the terminal device periodically starts an on duration timer (duration timer), and during the operation period of the duration timer, the terminal device needs to monitor the downlink control information, and at other times, the terminal does not need to monitor the downlink control information, and the durations of the DRX cycle and the duration timer are both configurable.
A problem that may arise if DRX only introduces a DRX cycle and duration timer is that the network device has only a short time to schedule the terminal device when data arrives just before the duration timer expires, and then only waits for the next duration timer to start. If a service is a large data volume service and the network device needs to schedule several times to transmit, part of the data will be delayed to the next duration timer, resulting in a delay.
For the above reasons, the current DRX mechanism further introduces an inactivity timer (inactivity timer), which is started when the terminal device receives a control message for scheduling a new transmission.
In particular, the DRX mechanism provides that the terminal device needs to listen for downlink control information as long as either of the inactivity timer and the duration timer is running. Therefore, the problem that the base station enters the DRX state due to the fact that the duration timer is overtime when the base station does not schedule the terminal equipment is finished can be avoided.
However, the inactivity timer is only useful for traffic that needs to be scheduled continuously. For example, a scenario where network devices need to be scheduled continuously due to large data arrivals, or a service that generates data continuously for a period of time. For services that do not need continuous scheduling, for example, services that only generate a small data packet, an excessively long inactivity timer may cause the terminal device to fail to enter the DRX state quickly, which may result in unnecessary power consumption.
In summary, the existing DRX mechanism cannot ensure that the UE can achieve power saving according to the optimal mechanism for the setting logic of the non-interactive timer.

Detailed Description
As noted in the background, the existing DRX mechanism setting logic for the inactivity timer cannot ensure that the UE can achieve power saving according to the optimal mechanism.
To solve the above technical problem, an embodiment of the present invention provides an inactivity timer control method for DRX, including: receiving control information; selecting an adapted candidate inactivity timer from a plurality of candidate inactivity timers as an inactivity timer to be controlled according to the control information; starting or restarting the inactivity timer to be controlled.
Those skilled in the art understand that the scheme of the embodiment of the present invention can more reasonably set the inactivity timer in the DRX mechanism, so that the UE can achieve energy saving according to an optimal mechanism. Specifically, a plurality of candidate inactivity timers are configured, and the most appropriate candidate inactivity timer is determined according to the currently received control information, so that the duration of the inactivity timer to be controlled is ensured to quickly enter the DRX state after the UE is scheduled on the basis of allowing the base station to complete the scheduling of the UE, thereby reducing the power consumption of the UE while considering low time delay.
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below.
Fig. 1 is a flowchart of an inactivity timer control method for DRX according to an embodiment of the present invention. The scheme of the embodiment can be applied to the user equipment side, such as executed by the UE.
Specifically, in this embodiment, referring to fig. 1, the inactivity timer control method for DRX may include the steps of:
step S101, receiving control information;
step S102, selecting an adapted candidate inactivity timer from a plurality of candidate inactivity timers as an inactivity timer to be controlled according to the control information;
step S103, starting or restarting the inactivity timer to be controlled.
More specifically, the control information may be information sent by the network side for scheduling the UE to perform data transmission. For example, the Control Information may include Downlink Control Information (DCI) carried on the PDCCH; the content scheduled by the control information may include uplink and downlink resources, and may further include adjusting the transmission power of the UE.
In one or more embodiments, each candidate inactivity timer may be associated with an index value (index), and the control information may include a standard index value of the inactivity timer to be controlled.
Accordingly, the step S102 may include the steps of: and matching the index values respectively associated with the plurality of candidate inactivity timers according to the standard index value, and determining the candidate inactivity timers with the matched index values as the inactivity timers to be controlled.
For example, the base station may configure a plurality of candidate inactivity timers and index values of the candidate inactivity timers, different candidate inactivity timers having different durations. Further, the base station may indicate the candidate inactivity timer, the index value, and the corresponding relationship between the candidate inactivity timer and the index value to the UE in advance through Radio Resource Control (RRC) signaling or the like.
When the UE needs to be scheduled this time, the base station may determine the inactivity timer to be controlled according to the service attribute of the data that needs to be transmitted in the scheduling this time, and indicate the index value of the inactivity timer to be controlled to the UE through the control information.
In response to receiving the control information, the UE may determine an inactivity timer to be controlled specified by the base station according to the index value, and restart or start the inactivity timer to be controlled.
In particular implementations, the index value may be indicated in an explicit indication. For example, the index value may be explicitly carried in the control information.
In specific implementation, the index value may also be indicated in an implicit indication manner, for example, the index value is indirectly indicated based on the time-frequency position where the control information is located, so as to reduce signaling overhead without adjusting the structure of the existing control information.
In a specific implementation, the to-be-controlled inactivity timer may be determined according to a service type of a data packet that needs to be transmitted in the current scheduling.
For example, for large packet traffic and continuous data traffic, a candidate inactivity timer with a longer duration may be selected from the plurality of candidate inactivity timers as the inactivity timer to be controlled. Wherein, the big data packet service means: a larger data volume may be reached instantaneously, one-time transmission may not be completed, and the service to which the data packet of the UE belongs needs to be called in several times; the continuous data service is as follows: and the service to which the data in the continuous arrival state belongs, such as a voice call service and the like.
For another example, for small packet traffic, a candidate inactivity timer with a shorter duration may be selected from the plurality of candidate inactivity timers as the inactivity timer to be controlled. Wherein, the small data packet service means: the data volume is small, and the service to which the data belongs can be transmitted in a single time in a short time.
Thus, the base station may directly instruct the UE to start a specific inactivity timer to ensure that the UE does not enter the DRX state before scheduling of the UE is completed.
In one or more embodiments, the candidate inactivity timer may be associated with a business attribute. Therefore, different candidate inactivity timers are configured according to the service attributes, and the most appropriate candidate inactivity timer is determined as the inactivity timer to be controlled according to the service attributes of the data to be transmitted scheduled by the current control information, so that the UE power consumption is reduced as much as possible while the data is ensured to be transmitted in time.
In a specific implementation, the Service attribute may be determined according to a Quality of Service (QoS) characteristic of a Service to which data to be transmitted belongs. Wherein the data to be transmitted is data carried by resources scheduled by the control information.
In particular implementations, the candidate inactivity timers may be in a one-to-one correspondence with traffic attributes.
In a specific implementation, multiple service attributes may be associated with the same candidate inactivity timer.
In a specific implementation, the association relationship between the candidate inactivity timer and the service attribute may be determined by the base station and indicate the UE in advance through RRC signaling or the like.
Accordingly, referring to fig. 2, the step S102 may include the steps of:
step S1021, determining the service attribute of the data to be transmitted according to the control information;
step S1022, selecting an adapted candidate inactivity timer from the plurality of candidate inactivity timers according to the service attribute as the inactivity timer to be controlled.
In one or more embodiments, the plurality of candidate inactivity timers may include a first set of candidate inactivity timers that may correspond to upstream traffic and a second set of candidate inactivity timers that may correspond to downstream traffic, the first set of candidate inactivity timers may include at least one candidate inactivity timer, and the second set of candidate inactivity timers may include at least one candidate inactivity timer.
Specifically, the base station may configure a plurality of candidate inactivity timers dedicated to uplink traffic and a plurality of candidate inactivity timers dedicated to downlink traffic, respectively, and for each set of candidate inactivity timers, the base station may further indicate in the form of an index value.
For example, when the first group of candidate inactivity timers and the second group of candidate inactivity timers each include three candidate inactivity timers, the first group of candidate inactivity timers and the second group of candidate inactivity timers can be distinguished by 3 index values respectively, which is beneficial to reducing the size of the control message and reducing the signaling overhead compared with the aforementioned scheme that the first group of candidate inactivity timers and the second group of candidate inactivity timers need to be indicated by 6 index values when uplink and downlink traffic are not distinguished.
In a specific implementation, the step S1022 may include the steps of: when the control information is used for scheduling downlink resources, determining that the service attribute of the data to be transmitted is downlink service, and selecting a candidate inactivity timer corresponding to the downlink service from the candidate inactivity timers as the inactivity timer to be controlled; and when the control information is used for scheduling uplink resources, determining that the service attribute of the data to be transmitted is uplink service, and selecting a candidate inactivity timer corresponding to the uplink service from the candidate inactivity timers as the inactivity timer to be controlled.
Still taking the example that the first and second sets of candidate inactivity timers each include three candidate inactivity timers and are respectively distinguished by 3 index values (e.g. 1, 2 and 3), when the received control information is used for scheduling downlink resources, the UE may select a candidate inactivity timer with a matching index value from the second set of candidate inactivity timers to perform a corresponding operation; when the received control information is used for scheduling uplink resources, the UE may select a candidate inactivity timer with a matching index value from the first set of candidate inactivity timers to perform a corresponding operation.
In a specific implementation, the first and second sets of candidate inactivity timers may each include one candidate inactivity timer, that is, uplink and downlink traffic respectively correspond to one candidate inactivity timer.
Accordingly, the UE may directly determine the first set of candidate inactivity timers or the second set of candidate inactivity timers as the to-be-controlled inactivity timer according to the type of resource scheduled by the control information.
Therefore, when the service attributes of the uplink and downlink services are different or are easy to distinguish, for example, the downlink service is mainly transmitted by a large data packet, the uplink service is mainly transmitted by a small discontinuous data packet, and a suitable candidate inactivity timer can be selected as the inactivity timer to be controlled in a targeted manner according to the currently scheduled resource type by configuring the candidate inactivity timers for the uplink and downlink services respectively. Therefore, when the service scheduled at this time is not a large data packet or a continuously incoming data packet, the UE can rapidly enter a sleep state.
In one or more embodiments, the step S1021 may include the steps of: and when the control information is used for scheduling downlink resources, determining the service attribute of the data to be transmitted according to first indication information included in the control information, wherein the first indication information comprises a characteristic parameter suitable for indicating the service attribute of the data to be transmitted.
In particular, the characteristic parameter may be selected from: an index value of a service attribute, a logical channel Identifier (ID), a QoS flow identifier, a QoS parameter set, a QoS parameter identifier, and a QoS parameter set identifier. The QoS parameter may include priority of a service, packet Delay Budget (PDB), packet Error Rate (PER), maximum Data Burst Volume (MDBV), guaranteed Bit Rate (GBR), maximum Bit Rate (MBR), aggregated Maximum Bit Rate (AMBR), jitter (jitter), and the like.
For example, when the service attribute is indicated based on the logical channel ID, it indicates that the base station can configure the inactivity timer of logical channel 1 to be 5ms and the inactivity timer of logical channel 2 to be 10ms through RRC signaling.
For another example, when the service attribute is indicated based on the QoS parameter or the QoS parameter set, the base station may configure, for example, an inactivity timer of 5ms for a service with a PDB of 5ms and 10ms for a service with a PDB of 10ms.
Therefore, when the scheduling is used for downlink data transmission, the base station can indicate the service attribute of the data to be transmitted through the control information, and the UE can select a proper inactive timer to be controlled according to the service attribute, so that the UE can enter a sleep state as early as possible while timely receiving the data to be transmitted, and low time delay and power consumption reduction are both achieved.
In one or more embodiments, the step S1021 may include: and when the control information is used for scheduling uplink resources, determining the service attribute of the service to be transmitted according to uplink data to be transmitted.
Further, when the uplink data to be sent is associated with multiple service attributes, the step S1022 may include the steps of: and determining the candidate inactivity timer with the shortest duration in the candidate inactivity timers respectively adapted to the associated service attributes as the inactivity timer to be controlled. Therefore, the UE can be ensured not to enter the sleep state at least before the service corresponding to the candidate inactivity timer with the shortest duration is transmitted.
In a variation, when the uplink data to be sent is associated with multiple service attributes, the step S1022 may include the steps of: and determining the candidate inactivity timer with the longest duration in the candidate inactivity timers respectively adapted by the associated multiple service attributes as the inactivity timer to be controlled. Therefore, all the data to be transmitted scheduled at this time can be ensured to be transmitted.
In another variation, when the uplink data to be transmitted is associated with a plurality of service attributes, the step S1022 may include the steps of: and determining candidate inactivity timers respectively adapted by the associated multiple service attributes as the inactivity timer to be controlled. Therefore, before the candidate inactivity timer with the longest duration expires, the UE does not enter the sleep state, and all the data to be transmitted scheduled at this time can be ensured to be transmitted.
In one or more embodiments, after performing the step S1022, the inactivity timer control method of this embodiment may further include the steps of: sending feedback information to indicate the inactivity timer to be controlled.
For example, when the control information is used to schedule uplink resources, after performing the step S1022, the UE may actively indicate to the base station the to-be-controlled inactivity timer that is started or restarted by itself.
Specifically, the feedback information may include second indication information, where the second indication information includes a characteristic parameter suitable for indicating a service attribute corresponding to the inactivity timer to be controlled.
For example, in executing step S1022, if the UE starts or restarts only one inactivity timer to be controlled, the UE may indicate, through the feedback information, an index value, a logical channel identifier, a QoS flow identifier, a QoS parameter set, a QoS parameter identifier, and/or a QoS parameter set identifier of a service attribute corresponding to the inactivity timer to be controlled of the base station.
For another example, in executing step S1022, if the UE starts or restarts multiple inactivity timers to be controlled, the UE may indicate, through the feedback information, an index value, a logical channel identifier, a QoS flow identifier, a QoS parameter set, a QoS parameter identifier, and/or a QoS parameter set identifier of a traffic attribute corresponding to the inactivity timer to be controlled with the longest (or the shortest) duration among the inactivity timers to be controlled of the base station.
For another example, in executing step S1022, if the UE starts or restarts multiple inactivity timers to be controlled, the UE may indicate, through the feedback information, index values of service attributes, logical channel identifiers, qoS flow identifiers, qoS parameters, qoS parameter sets, qoS parameter identifiers, and/or QoS parameter set identifiers corresponding to all the started or restarted inactivity timers to be controlled of the base station.
Therefore, the UE may start different inactivity timers to be controlled according to different services.
In a variation, each candidate inactivity timer may be associated with an index value, and the feedback information may include third indication information, where the third indication information may include the index value of the inactivity timer to be controlled.
For example, the base station may configure a plurality of candidate inactivity timers, a service attribute corresponding to each candidate inactivity timer, and an index value of each candidate inactivity timer, and indicate these information to the UE through RRC signaling or the like. In response to receiving the control information, the UE may start a corresponding inactivity timer to be controlled according to the service attribute of the uplink data packet to be sent, and notify the base station of the index value of the started inactivity timer to be controlled.
Specifically, when the step S1022 is executed, if the UE only starts or restarts one inactivity timer to be controlled, the UE may indicate, through the feedback information, the index value corresponding to the inactivity timer to be controlled to the base station.
For another example, in executing the step S1022, if the UE starts or restarts multiple inactivity timers to be controlled, the UE may indicate, through the feedback information, an index value corresponding to the inactivity timer to be controlled with the longest (or the shortest) duration among the inactivity timers to be controlled by the base station.
For another example, when the step S1022 is executed, if the UE starts or restarts multiple inactivity timers to be controlled, the UE may indicate, through the feedback information, all index values corresponding to the started or restarted inactivity timers to be controlled by the base station.
Thus, by adopting the scheme of the embodiment, the inactivity timer in the DRX mechanism can be set more reasonably, so that the UE can realize energy saving according to the optimal mechanism. Specifically, a plurality of candidate inactivity timers are configured, and the most appropriate candidate inactivity timer is determined according to the currently received control information, so that the duration of the inactivity timer to be controlled is ensured to quickly enter the DRX state after the UE is scheduled on the basis of allowing the base station to complete the scheduling of the UE, thereby reducing the power consumption of the UE while considering low time delay.
