Description

Technical Field

[0001] This disclosure relates to discontinuous reception configurations. Background Technology

[0002] In cellular communication systems, a User Equipment (UE) can be configured to keep its radio receiver active in a discontinuous manner according to a configured mode, thereby conserving energy by keeping the radio receiver off for a portion of the time. This mode, known as Discontinuous Receiver (DRX) configuration, defines an on-duration period—the time during which the receiver remains on—and a period defining the frequency at which the on-duration period occurs. Outside the on-duration period, the receiver is off, and the network aware of the DRX configuration will not transmit to the UE during the receiver-off period. In addition to the on-duration period and the period, the DRX configuration may include other parameters. Summary of the Invention

[0033] This paper discloses a method that enables a UE to change its DRX configuration without Radio Resource Control (RRC) signaling from the network, thereby allowing for more flexible and faster DRX configuration control. Specifically, the UE changes its DRX configuration based at least on a Bit Rate Control (RRC) indication from the network, allowing the network, which has already sent the RRC indication, to determine that the UE has changed its DRX configuration and subsequently send information to the UE using the new DRX configuration. Therefore, the UE can modify its DRX configuration without obtaining an explicit discontinuous reception DRX reconfiguration command from the network. This provides beneficial technical effects because DRX configuration adaptation occurs faster and with a lighter signaling burden on the network.

[0034] Figure 1 An example system according to at least some embodiments is illustrated. The system includes base stations 130 and 135 communicating with a UE (such as UE 110). A radio link connects base station 130 to UE 110. The radio link may be bidirectional, including an uplink UL and a downlink DL, whereby the UL is used to transmit information from UE 110 to base station 130, and the DL is used to transmit information from base station 130 to UE 110. A cellular communication system may include hundreds or thousands of base stations; for clarity, Figure 1 Only two base stations are shown in the diagram. Base stations can be distributed, as they comprise centralized units (CUs) and one or more distributed units (DUs). A base station is an example of a base station node.

[0035] Base station 130 is also communicatively coupled to core network node 140, which may include, for example, an evolved packet core (EPC) node, such as a Mobility Management Entity (MME) and Home Subscriber Server (HSS); or a 5G core network node, such as an Access and Mobility Management Function (AMF), a 5G Unified Data Repository (UDR), and a Call Session Management Function (SMF). Core network node 140 may be coupled to other core network nodes and network 150, for example, this network may include the Internet or a corporate network. The system can communicate with other networks via network 150. For clarity, in Figure 1 Examples of other core network nodes not shown include gateways and subscriber information repositories. Core network nodes can be virtualized because they can run as software modules on a computing substrate, allowing more than one virtualized network node to run on the same physical computing substrate. The network can be configured to operate according to a suitable cellular standard, such as fourth-generation 4G (also known as Long Term Evolution LTE), fifth-generation 5G (also known as New Radio NR), or the sixth-generation 6G standard defined by the 3GPP (3rd Generation Partnership Project). For interoperability, UEs attached to the network are configured to support the same standards as the network.

[0036] exist Figure 1In the example, base station 130 controls cells 130A and 130B, where UE 110 is... Figure 1 In the case shown, it is attached to cell 130A, and Figure 1 In the example, base station 135 controls cells 135A and 135B. The number of cells and / or beams can exceed [number missing]. Figure 1 The number shown. It is also possible for a base station to have a single cell or beam. Although illustrated as a sector, cells of the same base station can be omnidirectional and operate on, for example, different frequencies. Mobility events can include handovers from one beam to another within the same cell, or handovers from one cell to another. To support mobility procedures, UEs (including UE 110) are configured to perform mobility measurements to measure the signal strength of adjacent beams and / or cells, and report the results of these measurements to the network, which can then make decisions about mobility events, such as beam changes or cell handovers.

[0037] Base stations (BSs), such as base stations 130 and 135, are configured to send various information to the UE. In addition to user data, such as the content of voice and video calls, application data, and transmitted user files, the base station also sends various configuration data to control the functionality of the UE within its cell. A specific example of configuration information sent by the base station to the UE is a UL (Upper Limit) transmission grant, which allows the UE to use the system's radio resources to transmit the amount of data indicated in the grant. Furthermore, the base station provides DRX (Digital Ratio) configuration to the UE, for example, using RRC (Rate Control Code) signaling. For instance, the base station can configure the UE with two DRX configurations and a rule that allows the UE to change from one DRX configuration to the other in response to a bit rate control indication provided by the base station. The UE can be configured to change back to or to the default DRX configuration after the expiration of the validity period following the change to the other DRX configuration.

[0038] An example of a bit rate control indication is the Recommended Bit Rate (RBR), which can be transmitted from the network to the UE in the Media Access Control (MAC) control element (CE). The RBR procedure is used to provide the UE's MAC entity with information about the bit rate recommended by the base station. This bit rate is the physical layer RBR. The base station can send an RBR MAC CE to the UE's MAC entity to indicate the UE's RBR for a specific logical channel and a specific direction (i.e., uplink or downlink). Once the UE's MAC entity receives the RBR MAC CE, it indicates the recommended bit rate for the logical channel and direction indicated by the base station to the UE's upper layers. Typically, bit rate control indications are used by the network to guide the UE to transmit at a rate suitable for the network under current conditions. Bit rate control indications (e.g., RBRs) help allocate appropriate bandwidth for different types of services to ensure that high-priority services such as voice and video calls receive sufficient resources to maintain quality.

[0039] The UE's MAC entity can request the base station to provide a bit rate control indication, such as RBR, for a specific logical channel and direction. If the upper layer requests the MAC entity to query the base station for a bit rate control indication for a logical channel and direction (i.e., uplink or downlink), the MAC entity can responsively trigger a bit rate control indication query for that logical channel and direction if such a query has not yet been triggered.

[0040] For the 3GPP RBR mechanism, the following applies: If the UE's MAC entity has allocated UL resources for the new transmission, the MAC entity can instruct the UE's multiplexing and reassembly process to generate an RBR MAC CE query for the logical channel and direction. If the logical channel and direction used for this RBR query... bitRateQueryProhibitTimer It is configured but not yet running, and if the MAC entity has allocated UL resources for the new transmission and the allocated UL resources can accommodate the RBR MAC EC query and its subheadings. Once the RBR MAC CE query is sent, the UE will initiate the logical channel and direction for that RBR query. bitRateQueryProhibitTimer .

[0041] In the 3GPP system, the RBR MAC CE is identified by a MAC subheader with a Logical Channel Identifier (LCID), used for bit rate recommendation messages from the base station to the UE and bit rate recommendation query messages from the UE to the base station. It has a fixed size and consists of two octets: a six-bit LCID, a one-bit UL / DL indicator, a six-bit bit rate field, a one-bit bit rate multiplier, and reserved bits. The UL / DL indicator indicates whether the recommended bit rate or recommended bit rate query is applicable to the uplink or downlink. For the bit rate field, for bit rate recommendation, this value indicates the recommended bit rate. For bit rate recommendation query, this value can indicate the desired bit rate. A mapping from the bit rate field value to the bit rate value is configured. For the bit rate multiplier, for UEs supporting recommended bit rate multipliers, when configuring the logical channel indicated by the LCID field... bitRateMultiplier When a field is set to 1, the expected value of the indicated bit rate is multiplied by the value in the bit rate field. bitRateMultiplier The corresponding bit rate.

[0042] The DRX configuration includes an on duration and a period, and optionally additional parameters as described above. During the on duration, the UE monitors control channels, such as the Physical Downlink Control Channel (PDCCH); otherwise (i.e., during the off duration, the remaining portion of the DRX period defined by the period), the UE does not monitor control channels. If no scheduling from the network to the UE occurs during the active period, the UE can prevent its radio receiver from activating at the end of the on duration and wait until the end of the DRX period to wake up again and monitor control channels. Conversely, if the UE is scheduled and receives signals from the network during the on duration, it will keep its receiver active for a configurable period controlled by an inactivity timer that is (re)started each time the UE is scheduled, and will switch its receiver to inactive mode in response to the expiration of the inactivity timer. This mechanism avoids premature inactivity, i.e., while there is still data to be sent / received, and avoids associated delays. Other timers have been specified in 3GPP to keep the UE active, such as the Retransmission Timer (RTT) to support Hybrid Automatic Repeat Request (HARQ). Specifically, the retransmission timers for DL ​​and UL are started after a transport block is erroneously received / decoded, and their expiration indicates to the UE that it can wake up its main radio to receive the upcoming retransmission.

[0043] Two types of DRX cycles are defined to adjust the DRX configuration based on the different service modes of the UE: long DRX and short DRX. The former can be mandatory and is suitable for most scenarios, while the latter can be optional and is mainly defined for Voice over IP (VoIP) services due to their known short inter-packet arrival times. When using short DRX, this cycle is applied first and repeated a certain number of times before reverting to the long DRX cycle.

[0044] In 3GPP technology, DRX configuration includes the following parameters. drx-onDurationTimer The on-duration period at the start of the DRX cycle is defined. drx-SlotOffset Define startup drx-onDurationTimer The previous delay, drx- InactivityTimer Defines the duration following the control channel timing, in which the control channel indicates a new UL or DL ​​transmission for the MAC entity. drx-RetransmissionTimerDL Each DLHARQ procedure (excluding broadcast procedures) defines the maximum duration until a DL retransmission is received. drx-RetransmissionTimerUL (Each UL HARQ procedure) defines the maximum duration until the authorization for UL retransmission is received. drx- LongCycleStartOffset A long DRX period was defined, the period was set, and... drx-StartOffset The subframes in which long-period and short-period DRX periods begin are defined. drx-ShortCycle (Optional) Defines a short DRX period. drx- ShortCycleTimer (Optional) Defines the duration for which the UE should follow the short DRX cycle. drx-HARQ-RTT-TimerDL (Each DL HARQ procedure, excluding broadcast procedures) defines the minimum duration before the DL allocation for HARQ retransmission is anticipated by the MAC entity. drx-HARQ-RTT-TimerUL (Each UL HARQ procedure) defines the minimum duration before the UL HARQ retransmission authorization is expected by the MAC entity. ps-Wakeup (Optional) Defines the activation of associated functions when a DCP is detected but not detected. drx-onDurationTimer Configuration, ps-TransmitOtherPeriodicCSI (Optional) Defines the method for handling situations where the downlink control information DCP is configured for power saving but the associated drx-onDurationTimer is not started, under the condition that... drx-onDurationTimer The duration of the indication is configured to report periodic Channel State Indication (CSI) on the Physical Uplink Control Channel (PUCCH) during the specified period, which is not the Layer 1 Reference Signal Received Power (L1-RSRP). ps-TransmitPeriodicL1-RSRP (Optional) Defines the method for configuring DCP but associated with drx- onDurationTimer When not started, under the influence of drx-onDurationTimer The configuration for sending periodic CSI (i.e., L1-RSRP) on the PUCCH during the indicated duration.

[0045] DRX can be configured for each UE, and the network-side RRC entity can rely on optimization techniques to select a DRX configuration suitable for the UE's service activity at a given time. This means that when significant changes in service activity are detected, the network can adjust the UE's DRX configuration accordingly to achieve useful energy savings while avoiding latency that could compromise service quality. However, RRC signaling is a cumbersome signaling mechanism that involves latency.

[0046] It is foreseeable that, for example in Extended Reality (XR), application data rates will be actively adjusted in many use cases because adaptive data rates are an inherent characteristic of application services in XR, such as those based on the codecs used in XR. This bitrate control can be performed using a bitrate control instruction sent to the UE's MAC entity. Changes in bitrate can have the following effects: first, the network can decide to re-establish a session with the UE using a different Quality of Service (QoS) profile; second, the DRX configuration in the UE can be modified to account for different bitrates. For example, if the bitrate increases, it is possible that enabling duration segments will need to be performed more frequently to avoid exceeding data latency requirements.

[0047] When uplink congestion occurs, a bit rate control instruction can be sent from the network to enable applications in the UE to reduce their data rate. When applications in the UE achieve the new lower bit rate, the network can then provide service for the reduced UL traffic in a shorter time.

[0048] As described herein, a UE can be configured to autonomously determine and modify the active DRX configuration in the UE based on a bit rate control indication it receives from the network. Specifically, the UE can store DRX configurations and rule sets to activate them based on the bit rate control indication, such as RBR MAC CE. These DRX configurations provide different settings, including, for example, on-duration duration and period, thereby avoiding the need for RRC reconfiguration to modify the DRX configuration in the event of congestion. Alternatively, the UE can be provided with one or more rules to update the active DRX configuration (i.e., update an appropriate subset of the parameters of the active DRX configuration, such as an appropriate subset including the length of the on-duration duration) without switching to a single, complete DRX configuration. The active DRX configuration is one of several DRX configurations configured by the network, which the UE and the network use to determine the UE state, such as when the UE is active or inactive. When the UE is inactive, it can be in sleep mode and its receiver can be turned off, and when the receiver is off, the network should not schedule data transmission for the UE.

[0049] Figure 2 The diagram illustrates DRX reconfiguration according to at least some embodiments. Time progresses from left to right along the horizontal axis. Initially, during a time period 210, there are two complete on-duration segments while the UE keeps its radio receiver active and listens for messages from the network. The network provides a bit rate control indication, labeled RBR in the diagram, to halve the recommended bit rate associated with the active logical channel. The UE responds to this by modifying its DRX configuration so that, after the change, there is only one complete on-duration segment during a time period of the same length 210. In this update to the DRX configuration, the on-duration length may remain unchanged.

[0050] exist Figure 2 In the example, the UE is configured to wait a pre-configured length of time, marked "t_DRX" in the diagram, after receiving a bit rate control indication from the network and before performing a modification to the active DRX configuration. This is beneficial because there may be data waiting to be transmitted in the buffer, and immediately modifying the DRX configuration in response to the bit rate control indication would risk delaying the buffered data, as the new DRX configuration in this example provides less opportunity to transmit to the UE. Furthermore, this delay allows for possible delays on the application side to adapt its codec to the recently indicated bit rate. Therefore, the buffer can be at least partially cleared during the pre-configured length of time before the DRX modification is performed, since the application has already reduced its data generation rate.

[0051] In general, the UE is configured to determine whether to modify the active DRX configuration based at least in part on a bit rate control indication, without obtaining an explicit discontinuous receive DRX reconfiguration command from the network. In other words, the network does not explicitly instruct the UE to modify the DRX configuration, such as via RRC; instead, the UE uses the bit rate control indication as an implicit instruction to modify the DRX configuration in addition to modifying the bit rate. For example, the bit rate control indication may be delivered in a MAC CE. Specifically, the bit rate control indication may be an RBR MAC CE, but it may also take another form. The bit rate control indication typically informs the UE of the bit rate it should strive for, for example, in a specific logical channel. The UE may be provided with one or more rules that enable the UE to select a new DRX configuration or implement a modification of the active DRX configuration based on the bit rate control indication from the network. In some embodiments, the rule takes both the bit rate control indication and the current active DRX configuration as input and produces a new DRX configuration as output. For example, the network may use RRC signaling to configure multiple rules and multiple alternative DRX configurations in the UE. In addition to rules, configurations can be used to determine whether to modify the active DRX configuration based on bitrate control indications. For example, such configurations can include parameters used in the rule's determination, such as a recommended bitrate range for a particular DRX configuration. In some embodiments, the rule includes the configuration.

[0052] As described above, modifying the UE's active DRX configuration can include changing from the active DRX configuration to a second DRX configuration received from the network in the UE. The second DRX configuration can be received in the UE before the bit rate control indication is received in the UE. Alternatively, modifying the UE's active DRX configuration can include changing one or more parameters of the active DRX configuration while keeping other parameters of the active DRX configuration unchanged. For example, the modification can include only modifying the on-duration and / or period. For example, the drx-onDurationTimer of the active DRX configuration can be modified by multiplying it by a multiplier. As another example, the drx-InactivityTimer of the active DRX configuration can be adjusted by multiplying by a multiplier or by applying a non-zero offset value to modify the parameter accordingly.

[0053] In some embodiments, the UE is configured to revert to the default DRX configuration in response to the expiration of a validity period following a modification of the active DRX configuration that the UE has performed at least partially based on a bit rate control indication. This can be useful, for example, when a higher bit rate burst is generated in an application, and the DRX configuration reverts to the default value after the burst subsides without requiring any signaling.

[0054] In at least some embodiments, the network is configured to provide instructions to the UE that configure the UE to enable or disable determining whether to modify the UE's active DRX configuration, at least in part, based on a bit rate control indication. In other words, the network can use a bit rate control indication to implicitly control the enabling or disabling of DRX configurations. This provides the benefit of reducing the risk of disagreements between the UE and the network regarding which DRX configuration is active in the UE when applications with predictable bit rates are used.

[0055] In at least some embodiments, the UE is configured to determine whether to modify the active DRX configuration based on both a bitrate control indication and an acknowledgment message received in the device after the bitrate control indication is received. In other words, in these embodiments, the UE does not change the DRX configuration solely in response to the bitrate control indication, but rather in response to receiving an acknowledgment message after the bitrate control message. The UE can be configured to wait for an acknowledgment message for a period of time after receiving the bitrate control indication; this period can be referred to as an observation period. For example, if during the observation period the network concludes that the actual experienced data rate matches the rate indicated in the bitrate control indication, or is within X% of the value in the bitrate control indication, the network can send an acknowledgment message. If the observation period expires without an acknowledgment message arriving, the UE will not implement the DRX configuration modification determined based on the bitrate control message.

[0056] On the base station side, the base station is configured to determine whether the UE will modify its DRX configuration in response to a bit rate control indication sent by the base station. The base station will know one or more rules that the UE will use when determining whether to modify the active DRX configuration based on the bit rate control indication, because the base station or another base station will provide this rule to the UE. Alternatively, for example, the rule can be static and determined during the standardization process. Therefore, the base station can adapt to the UE's implicitly changed DRX configuration and send messages to the UE using the new DRX configuration.

[0057] For example, a base station can be configured to determine the mobility state of the UE and, based on the determined mobility state, disable or enable implicitly triggered modifications to the active DRX configuration in the UE. Specifically, the base station can be configured to enable the UE's autonomous DRX configuration modification when the UE's mobility state is low, i.e., when the UE's movement speed is below a threshold speed, and the base station can be configured to disable the UE's autonomous DRX configuration modification when the UE moves at a speed exceeding the threshold speed. When the UE's autonomous DRX configuration modification is disabled, the UE will only change its active DRX configuration when explicitly commanded by the network (e.g., using RRC signaling).

[0058] As an example of rules that can be stored in the UE, autonomous and deterministic rules for triggering DRX reconfiguration may include the following. In response to the bit rate value indicated in the bit rate control indication falling within the bit rate range defined in the rule, the UE may be triggered to select the DRX configuration corresponding to the bit rate range without signaling exchange with the network to switch to a different DRX configuration. These actions may be based on parameters configured by the network, so that the network knows and can predict the behavior of the UE. For example, if the bit rate is halved, the period of the DRX cycle can be doubled. In another example, if the bit rate is halved, the on duration can be halved while the DRX cycle can remain unchanged. A variation of this example is that a plurality of complete DRX configuration sets are stored in the UE, and the rule based on the indicated bit rate in the bit rate control indication specifies a mapping from the indicated bit rate set to the DRX configuration set, so that the DRX configuration can be selected based on the rule and the bit rate indicated in the bit rate control indication.

[0059] In some embodiments, at least two thresholds are used to configure a hysteresis mechanism, which may be configured and activated by the network. For the case with two configurations (e.g., default and alternative), two thresholds R1 and R2 (where R2>R1) can be defined. When the bit rate R indicated in the bit rate control indication becomes greater than R2 (R>R2), the UE switches to the alternative DRX configuration, and does not switch back to the default DRX configuration until R<R1. Note that the UE may also be configured to switch to the alternative DRX configuration when R<R2, and switch back to the default DRX configuration when R>R1. Such a hysteresis rule may depend on the number of UL occasions between the default configuration and the alternative configuration.

[0060] Table 1 below lists a list of possible example triggers and subsequent actions, which does not limit the scope of the present disclosure. In at least one embodiment, the trigger includes at least a condition related to the mobility state of the UE. For example, the condition may activate the trigger for autonomous DRX switching / activation in Table 1 in response to low or medium mobility of the UE, while when the mobility of the UE is high, the network still fully controls DRX activation. Low, medium and high mobility can be defined by appropriately configured mobility thresholds, for example in terms of UE speed. In some embodiments, the UE is configured with a plurality of DRX configuration sets and corresponding rule sets based on the indicated bit rate, which are mapped to each DRX configuration in the DRX configurations.

[0061] The following table describes an example of rules that enable determining and modifying the active DRX configuration in the UE based on a bit rate control indication. Table 1

[0073] Figure 4 The diagram illustrates signaling according to at least some embodiments. On the vertical axis, the left side is... Figure 1 Base station 130, on the right is Figure 1 UE 110. Time progresses from top to bottom.

[0074] Prior to phase 410, the UE could indicate to the network its ability to store multiple DRX configurations and, at least partially, to modify its active DRX configuration based on a bit rate control indication without obtaining an explicit DRX reconfiguration command from the network. In phase 410, base station 130 configures UE 110 with a set of at least two DRX configurations. Furthermore, the base station provides the UE with a set of one or more rules for autonomously switching to each DRX configuration based on the corresponding bit rate indicated in the bit rate control indication from the network. In other words, the rules enable the selection of one DRX configuration as the new active DRX configuration based on the bit rate indicated in the bit rate control indication. In other words, the NW configures a set of rules for autonomous switching for each DRX configuration based on the corresponding bit rate control indication. Therefore, the UE can be provided with a list of triggers and their corresponding DRX configurations.

[0075] In phase 420, the UE prepares a bit rate control indication query, and in phase 430, the prepared bit rate control indication query is sent from the UE 110 to the base station 130. In phase 440, the base station responds by sending a bit rate control indication to the UE 110. As mentioned above, this bit rate control indication can be, for example, an RBR MAC CE. In some embodiments or cases, the base station may send a bit rate control indication without receiving a query from the UE 110. Therefore, phases 420 and 430 are optional.

[0076] In phase 455, UE 110 determines whether to modify the UE's active DRX configuration based on the bit rate control indication and the rules(s) configured in the UE. If so, the UE also selects a DRX configuration to switch to from the DRX configurations stored in the UE. In parallel, in phase 450, the base station uses its knowledge of the bit rate control indication and the rules(s) configured in the UE from phase 440 to perform a similar determination as to whether the UE will decide to modify its active DRX configuration.

[0077] In phase 460, the UE performs a modification to the active DRX configuration, discontinuing the use of the earlier active DRX configuration and beginning to use the selected DRX configuration as the new active DRX configuration. Subsequently, in phase 470, base station 130 and UE 110 communicate with each other using the DRX configuration selected in phase 455, based at least in part on the bit rate in the bit rate control indication.

[0078] Overall, dynamic and implicit changes to DRX configuration based on data rate variations allow for rapid adaptation and help avoid buffer buildup before the applied data rate is modified. Furthermore, this rapid adaptation approach can improve UE power efficiency. This dynamic adaptation is based on pre-configured rules that do not require additional explicit signaling in the form of DRX configuration switching commands.
