Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method and device for reducing communication interruption, a storage medium, a terminal, and a base station. Background Art

[0002] In the existing New Radio (NR) system, when the user equipment (UE) is configured with carrier aggregation, the network will introduce an interruption when the UE activates / deactivates / dormancy a service cell through signaling or a configured timer. For example, when activating a service cell, the service cells affected by the UE as specified in the existing protocol include the interruption requirements of service cells in the same frequency band (Band) (also called Intra-Band) and the interruption requirements of service cells across frequency bands (Inter-Band). For example, the existing protocol specifies the interruption duration for SCell activation / deactivation for Intra-band CA in the same frequency band of carrier aggregation (CA) and the interruption duration for SCell activation / deactivation for Inter-band CA.

[0003] During the interruption period, the communication between the base station and the UE is interrupted. For example, when the base station sends a signaling to activate the secondary cell (SCell), the base station knows the time slot in which the UE applies the signaling. Starting from this time slot, according to the protocol specifications, the base station knows that the UE cannot receive its own downlink control signaling and will not send signals to itself during the interruption period.

[0004] With the improvement of UE design level, and the possibility that UE uses different RF transceivers to serve different service cells, when the base station activates / deactivates / sleeps service cells, the interruptions caused to different service cells may be different, or some service cells may not need to be interrupted because they are not affected. However, if the existing mechanism is adopted, the base station always believes that activating / deactivating / sleeping service cells will cause consistent interruptions (i.e., the interruption duration specified by the protocol), which will cause additional communication delays and reduced spectrum efficiency for new smart terminals or UEs using multiple RF transceivers.

[0042] As mentioned in the background art, the interruption mechanism in the prior art will cause additional communication delays and reduced spectrum efficiency for new intelligent terminals or UEs using multiple radio frequency transceivers.

[0043] To solve the above problems, an embodiment of the present invention provides a method for reducing communication interruptions, the method comprising: determining uplink signaling, the uplink signaling including attribute information of an applicable interruption for a UE; sending the uplink signaling to a base station, so that the base station determines the interruption type and the interruption duration corresponding to the interruption according to the attribute information, and communicates with the UE.

[0044] Through this solution, the UE can flexibly configure the attribute information of the interruption used by itself (such as interruption duration, interruption type, etc.) to reduce communication interruption and improve spectrum efficiency.

[0045] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] See also Figure 1 , Figure 1 The present invention is a flowchart of a method for reducing communication interruption according to an embodiment of the present invention, wherein the method comprises:

[0047] Step S101, determining uplink signaling, where the uplink signaling includes attribute information of UE applicable interruption;

[0048] Step S102: Send the uplink signaling to a base station, so that the base station determines the interruption type and the interruption duration corresponding to the interruption according to the attribute information, and communicates with the UE.

[0049] in, Figure 1 The method can be executed by the UE side. The attribute information of the interruption includes the interruption type, the interruption duration corresponding to each interruption type, the affected / unaffected serving cell (Serving Cell, which may include a primary cell (PCell) and / or a secondary cell (SCell)) or a frequency band (Band) and other information related to the interruption applicable to the UE.

[0050] Specifically, the UE determines the interruption type applicable to it, the interruption duration corresponding to each interruption type, and other attribute information based on its own communication capabilities and other factors, and sends it to the base station (or the network side) through uplink signaling, so that the base station does not communicate with the UE or the affected service cell within the corresponding interruption duration when the UE enters the corresponding interruption according to the UE's instructions.

[0051] The communication between the base station or the network side and the UE refers to data transmission and / or signaling transmission between the base station and the network side.

[0052] Optionally, the interruption type includes at least one of an interruption caused by activation of a secondary cell (SCell), an interruption caused by deactivation of an SCell, an interruption caused by SCell dormancy, and an interruption caused by switching of a bandwidth part (Bandwidth Part, BWP for short).

[0053] The interruption caused by the activation of SCell includes the interruption caused by the SCell switching from the dormant state to the activated state and / or the interruption caused by the SCell switching from the deactivated state to the activated state; the interruption caused by the deactivation of SCell includes the interruption caused by the SCell switching from the activated state to the deactivated state and / or the interruption caused by the SCell switching from the dormant state to the deactivated state; the interruption caused by the dormancy of SCell includes the interruption caused by the SCell switching from the activated state to the dormant state and / or the interruption caused by the SCell switching from the deactivated state to the dormant state. These interruption times can be the same or different, and can be set according to the needs of the UE, or according to the service carrier, or according to the frequency band.

[0054] BWP switching refers to the switching of a BWP activated in a serving cell. For example, if the BWP configured in the serving cell includes BWP1 and BWP2, the base station can notify the UE to switch from BWP1 bandwidth to BWP2 through downlink control signaling.

[0055] Among them, the interruption caused by activation / deactivation / sleep of SCell is applicable to SCell, and the interruption caused by BWP switching is applicable to PCell and SCell.

[0056] Optionally, the uplink signaling includes at least one of RRC reconfiguration completion signaling, RRC recovery completion signaling, and UE capability information.

[0057] That is, the UE can indicate the attribute information of the applicable interruption of the UE to the base station through RRC reconfiguration completion signaling in the RRC reconfiguration process; it can also indicate the attribute information of the applicable interruption of the UE to the base station through RRC recovery completion signaling in the RRC recovery process; it can also indicate the attribute information of the applicable interruption of the UE to the base station through UE capability information in the UE capability acquisition process.

[0058] When the UE indicates the attribute information of the UE applicable interruption to the base station through the three types of uplink signaling, if there is any updated content, the last indication to the base station shall prevail.

[0059] In this embodiment, the UE can report its applicable interruption attribute information to the base station according to its own capabilities. When the UE enters a certain type of interruption, the base station will not communicate with the UE or communicate with an unaffected service cell within the corresponding interruption duration according to the UE's instructions, thereby improving spectrum efficiency and system performance.

[0060] In one embodiment, see Figure 1 and Figure 2 , Figure 2 is a schematic diagram of an RRC reconfiguration process, Figure 1 Before sending the uplink signaling to the base station in step S102, the following may also be included: receiving the base station through RRC reconfiguration (ie Figure 2 RRC Reconfiguration) message in the RRC Reconfiguration) message sends the configuration information of the serving cell; Figure 1 The sending of uplink signaling to the base station in step S102 includes: sending an RRC reconfiguration completion (i.e. Figure 2 The RRC reconfiguration complete signaling includes one or more interruption types for the serving cell and an interruption duration corresponding to at least one interruption type.

[0061] That is, during the RRC reconfiguration process, the UE sends the attribute information of the UE applicable interruption through the RRC reconfiguration completion signaling. Specifically, the UE can carry one or more applicable interruption types and the interruption duration corresponding to each interruption type in the RRC reconfiguration completion signaling and send it to the base station.

[0062] Optionally, when the UE indicates attribute information of multiple interruptions in the RRC reconfiguration completion signaling, it may only indicate the interruption duration corresponding to some of the interruption types, and the interruption duration not indicated in the RRC reconfiguration completion signaling may use the interruption duration set in the existing protocol.

[0063] In one embodiment, see Figure 1 and Figure 3 , Figure 3 A schematic diagram of an RRC recovery process. In the RRC recovery process, the UE sends an RRC recovery request (such as Figure 3 RRC Resume Request as shown, Figure 1 Before sending the uplink signaling to the base station in step S102, the process may also include: receiving a recovery message (such as Figure 3 Configuration information of the serving cell sent by the RRCResume) message shown; Figure 1The sending of uplink signaling to the base station in step S102 may include: sending an RRC resume complete signaling to the base station, wherein the RRC resume complete signaling includes one or more interruption types for the serving cell and an interruption duration corresponding to at least one interruption type.

[0064] During the RRC recovery process, the base station can send the configuration of different service cells to the UE through the RRC Resume message, and the UE can send the attribute information of the UE applicable interruption through the RRC recovery completion signaling based on the currently configured service cell. Specifically, the UE can carry one or more applicable interruption types and the interruption duration corresponding to each interruption type in the RRC recovery completion signaling and send it to the base station.

[0065] Optionally, when the UE indicates attribute information of multiple interruptions in the RRC recovery completion signaling, it may only indicate the interruption duration corresponding to some of the interruption types, and the interruption duration not indicated in the RRC recovery completion signaling may use the interruption duration set in the existing protocol.

[0066] Optional, for Figure 2 and Figure 3 The RRC reconfiguration completion signaling or the RRC recovery completion signaling further indicates a serving cell or a frequency band (Band) that is / is not affected by the interruption.

[0067] Among them, one frequency band may correspond to one or more service cells, and the service cells affected / not affected by the interruption may be indicated by indicating the Band affected / not affected by the interruption.

[0068] The UE may indicate the interruption duration of one interruption type and the affected service cells or frequency bands in the same uplink signaling or in different uplink signaling. The UE may indicate only the interruption duration of one interruption type, or only the service cells or frequency bands affected by the interruption. If some service cells use the interruption duration set by the protocol, the UE may not indicate the interruption information applicable to these service cells in the uplink signaling, and may only indicate the interruption information of service cells that are different from the interruption duration set by the protocol.

[0069] In a specific embodiment, please continue to see Figure 2 and Figure 3, the UE accesses the network in NR and carries out communication services. Due to the needs of the service and the capability of the UE, the base station configures carrier aggregation for the UE. At this time, the UE is configured with four service cells, including the primary cell PCell, SCell1, SCell2 and SCell3. Among them, PCell and SCell1 belong to the same band, and SCell2 and SCell3 belong to another band. Figure 2 In the process, the base station can send the configuration information of the secondary cells (SCell1, SCell2, SCell3) to the UE through the RRC reconfiguration message. The configuration information may include the frequency, bandwidth, subcarrier spacing adopted, bandwidth part BWP (Bandwidth Part) parameters contained in each cell, etc.

[0070] After receiving the configuration of the secondary cell sent by the base station, the UE applies the configuration information. For the UE, two RF transceivers are used to serve the serving cells in two bands respectively. For example, RF transceiver 1 is used to serve PCell and SCell1, and RF transceiver 2 is used to serve SCell2 and SCell3.

[0071] Therefore, the UE can indicate the interruption duration of different types of interruptions to the base station through the RRC reconfiguration completion signaling. For example, for the interruption type of activating SCell1, the affected one is PCell, and the corresponding interruption duration. At this time, the interruption type that can be indicated by the RRC reconfiguration completion signaling includes the interruption of activating SCell1, the corresponding interruption duration is M time slots (Slot), the affected service cell is PCell / the unaffected service cells are SCell2 and SCell3. In addition, the UE can indicate the service cell affected by the interruption type by indicating the affected Band, such as when activating SCell1, only indicating that the affected Band is the Band to which SCell1 belongs.

[0072] Figure 3 The attribute information of indicating the UE applicable interruption through the RRC recovery completion instruction can refer to the above specific embodiment, which will not be described in detail here.

[0073] It should be noted that if the protocol or other pre-configured signaling indicates the interruption type that the UE can report indicated by the RRC reconfiguration completion signaling / RRC recovery completion signaling, then the RRC reconfiguration completion signaling / RRC recovery completion signaling does not need to indicate the interruption type. The UE only needs to indicate the affected service cell or Band through the RRC reconfiguration completion signaling / RRC recovery completion signaling, and / or the interruption duration corresponding to the interruption type reported by the UE.

[0074] In this embodiment, if the UE has accessed the NR network and the base station has configured a service cell (including PCell and SCell) for the UE, the UE can indicate to the base station the attribute information of its applicable interruption based on the configured service cell, and the indicated signaling can be the RRC reconfiguration completion signaling or the RRC recovery completion signaling.

[0075] In one embodiment, see Figure 1 and Figure 4 , Figure 4 A schematic diagram of a UE capability acquisition process; Figure 1 The sending of uplink signaling to the base station in step S102 includes: during the process of UE accessing the network, when the base station obtains the capability of the UE through the UE capability acquisition process, indicating the attribute information of the interruption through the UE capability information.

[0076] Some UEs use new design techniques to greatly improve performance. For different interruption types, the interruption duration is significantly shorter than that specified in the existing protocol. Therefore, when the UE is accessing the network, when the base station sends a UE capability query (such as Figure 4 UE Capability Enquiry in the UE Capability Enquiry), the UE can report the UE capability information (such as Figure 4 The UECapability Information in the UECapability Information indicates the attribute information of the UE applicable interruption. For example, it indicates the minimum interruption duration required when activating the SCell.

[0077] Optionally, the UE capability information further indicates one or more frequency bands that are affected / not affected by the interruption.

[0078] When the UE accesses the network, it can report the attribute information of the interruption corresponding to the Band / Band combination it supports to the base station. At this time, the amount of data reported by the UE is relatively large. The base station can select the Band / Band combination to be used after the UE accesses the network according to the needs of its own network deployment, and request the UE to report the attribute information of the interruption corresponding to these Band / Band combinations through UE capability query signaling. At this time, the attribute information indicates one or more Bands affected / not affected by the interruption, and for each Band, it can further indicate the carrier affected / not affected by the interruption.

[0079] For UE capability reporting, other implementation methods that can be used are: usually the base station will indicate the Band list (Frequency Band List Filter) that needs to be reported in the UE capability inquiry (UECapability Enquiry). For the Bands and Band Combinations that need to be reported, the UE can indicate different interruption types and affected / unaffected Bands, corresponding interruption duration and other attribute information. Because the UE has not yet configured the service cells in certain Bands, such as only one activated PCell at present, but the UE can indicate the Bands affected by different interruption types in the UE capability information. For example, for the Band combination supported by the UE (including Band1 and Band2), the UE can indicate the affected / unaffected Bands when activating the service cell in Band1, as well as the interruption duration corresponding to the interruption.

[0080] In one embodiment, the interruption duration is the minimum interruption duration that the UE can support. Figure 1 After sending the uplink signaling to the base station in step S102, the method further includes: receiving an interruption duration configuration signaling returned by the base station according to the uplink signaling, wherein the interruption duration configuration signaling indicates application of the minimum interruption duration or an actually applied interruption duration.

[0081] Optionally, for Figure 4 In the UE capability acquisition process in , after the base station receives the UE capability (that is, the base station receives the UE Capability Information), if the minimum interruption duration indicated by the UE is applied, the minimum interruption delay of the UE can be indicated to the UE through RRC reconfiguration signaling. If the base station needs to apply other interruption durations, such as the duration is greater than the minimum interruption duration, the base station can indicate the actual interruption duration of the application through RRC reconfiguration signaling.

[0082] for Figure 2 and Figure 3 In the indication method in, the base station can use other downlink signaling to indicate the application of the minimum interruption duration or the actual application interruption duration.

[0083] Optionally, the interruption duration is represented by a slot number or an orthogonal frequency division multiplexing (OFDM) symbol number, or an actual time length.

[0084] That is, when the interruption duration is indicated in the uplink signaling, it may indicate how many slots or OFDM symbols it corresponds to.

[0085] See also Figure 5 The embodiment of the present invention further provides a method for reducing communication interruption, the method comprising:

[0086] Step S501, receiving uplink signaling sent by a UE, where the uplink signaling includes attribute information of applicable interruption of the UE;

[0092] Optionally, the RRC reconfiguration completion signaling or the RRC recovery completion signaling further indicates a service cell or frequency band affected by / not affected by the interruption.

[0093] Optionally, the receiving of uplink signaling sent by the UE includes: during the process of the UE accessing the network, when acquiring the UE capability through the UE capability acquisition process, receiving UE capability information sent by the UE, the UE capability information indicating attribute information of the interruption.

[0094] Optionally, the UE capability information further indicates one or more frequency bands affected / not affected by the interruption.
