Description

Methods executed by user equipment and user equipment

Technical field

The present invention relates to the field of wireless communication technology, and in particular to a method executed by user equipment and user equipment.

Background technique

In recent years, multi-USIM card devices have become increasingly popular. For example, a user installs two USIM cards on a mobile phone that supports multiple USIM cards. One USIM card is used to subscribe to private services, and the other USIM card is used to subscribe to office services. Existing devices that support multiple USIM cards are implemented by manufacturers and have not yet been standardized by 3GPP. As a result, different manufacturers adopt different implementation methods, and the behavior of user equipment UE is also different. In the existing implementation, if these USIM cards are registered with the network respectively (either to the same network or to two or more networks), the UE needs to receive paging from these networks. Based on the UE's transceiver capabilities, it may One situation that exists is that when the UE receives paging from the current network, another network also initiates paging for it, or when the UE is communicating with a network, another network initiates paging for it. If the UE switches between different networks, one possible result is that the UE can no longer receive data from the current network when the UE switches to another network. This will harm network performance, for example, the network sends a paging to the UE but the UE does not receive the paging because it switches to another network, or the UE switches to another network and cannot receive the schedule of the current network. Some manufacturers have proposed 3GPP standardization research on the behavior of UEs with multiple USIM cards accessing networks and related networks. The benefit is that network performance can be improved based on predictable UE behavior.

Based on the above reasons, in December 2019, at the 3rd Generation Partnership Project (3GPP) RAN#86 plenary meeting, vivo proposed a work project for version 17 multi-SIM card equipment (see non-patent literature : RP-193263: New WID: Support of Multi-SIM devices in Rel-17), and approved. One of the goals of this work item is to define a mechanism for a UE to notify Network A when it leaves Network A, where Network A is NR, network B is LTE or NR, and the UE is single-receiver and single-transmit (Single-Rx/Single-Tx) or the UE is dual-receiver and single-transmit (Dual-Rx/Single-Tx).

In December 2021, at the 3GPP RAN#94 meeting, it was agreed to further enhance the multi-USIM card UE with dual reception and dual transmission capabilities (dual Rx/Tx), so that the UE can be in the RRC connection state in two networks at the same time (see non- Patent document: RP-213584 New WI on DualTx Rx MUSIM enhancements).

In this disclosure, network, base station (or base station node) and RAN can be used interchangeably. The network can be a long-term evolution LTE network, an enhanced long-term evolution eLTE network, an NR network, or other networks defined in subsequent evolution versions of 3GPP. network.

In this disclosure, user equipment UE may refer to a device that physically supports multiple USIM cards (two or more USIM cards), and the USIM may be a physical SIM or eSIM (USIM can be a physical SIM or eSIM). The device is equipped with two or more USIM cards, and each USIM card is associated with a network. The multiple USIM cards can be from the same operator or different operators. From a network perspective, different USIM cards can correspond to different UEs, and each USIM card corresponds to one UE. Unless otherwise specified, this disclosure does not make this distinction. Those skilled in the art can easily determine according to the context whether the UE refers to a UE that supports multiple USIM cards or a UE corresponding to each USIM card in a device that supports multiple USIM cards. User equipment configured with multiple USIM cards can receive and/or send data from multiple networks through time division multiplexing and other methods using single receive and single transmit or dual receive and single transmit. A UE with two Tx and two Rx (dual transmit and dual receive) can send data to two networks at the same time, and can also receive data from two networks at the same time.

In the embodiment of this disclosure, the UE is configured with two USIM cards as an example. Those skilled in the art can easily extend it to the case of multiple USIM cards.

The process of the user equipment UE configured with multiple USIM cards requesting the network to configure the MUSIM interval is as follows: For the case where the first network (denoted as network A) is in the RRC connected state and the second network (denoted as network B) is in the RRC idle state or RRC The inactive UE sends a UE assistance information message to Network A for MUSIM purposes to request one or more MUSIM intervals. Based on the UE assistance information message, Network A configures one or more MUSIM intervals for the UE.

For a UE working in dual connectivity mode, that is, a UE with at least dual reception and dual transmission capabilities is in the RRC connected state in the first network (hereinafter referred to as network A) and is configured with dual connectivity. The UE is configured with the primary cell group MCG and the secondary cell group SCG by network A. If the UE is in the RRC idle state or RRC inactive state in network B, how the UE requests network A to configure the MUSIM interval for network B is a problem that needs to be solved. . In addition, after network A configures one or more MUSIM intervals for network B for the UE, but the UE requests network A to deactivate or release the SCG due to the MUSIM purpose (to establish an RRC connection with network B), the network A How to handle the MUSIM interval configured for the UE is also a problem that needs to be solved.

For a UE working in carrier aggregation mode, that is, a UE with at least dual reception and dual transmission capabilities is in the RRC connected state in the first network (hereinafter referred to as network A) and is configured with one or more cell SCells. If the UE is in the network B is in RRC idle state or RRC inactive state. How UE requests network A to configure the MUSIM interval for network B is a problem that needs to be solved.

The following describes the embodiment of the present disclosure in detail in three scenarios.

Scenario 1 MUSIM interval is applicable to UE

In scenario 1, the MUSIM interval affects the scheduling of all serving cells in network A. Within the time limited by the MUSIM interval, the UE follows the operations that should be performed within the scheduling interval on all serving cells. In other words, the MUSIM interval is valid for all serving cells of the UE. So in dual connectivity, what happens to the configured MUSIM interval when the SCG is deactivated? When SCG is activated, what happens to the configured MUSIM interval?

Example 1-1 If the SCG is deactivated, the MUSIM interval becomes invalid; if the SCG is activated, the MUSIM interval takes effect.

In this embodiment, the MUSIM interval is only valid when the SCG is not deactivated. As shown in Figure 1, in step S101, the activation status of the SCG (that is, whether it is deactivated or activated) is determined. According to the judgment result, in step S102, when the SCG is deactivated, the configured MUSIM interval Invalid; in step S103, when the SCG is activated, the configured MUSIM interval takes effect.

Specifically, if the UE is configured with the MUSIM interval and the SCG is active (i.e. SCG CG is activated), for the MUSIM interval, during the MUSIM interval, on the current network (all serving cells or all frequencies of the current network), the MAC entity may perform at least one of the following:

1. Do not perform the transmission of hybrid automatic repeat request HARQ feedback, scheduling request SR and channel state information CSI;

2. Do not report the detection reference signal SRS;

3. Do not transmit on the uplink shared channel UL-SCH (optional, message 3Msg3 or message A MSGA payload of the random access process can be transmitted);

4. Do not monitor the physical downlink control channel PDCCH and do not receive the downlink shared channel DL-SCH (optional, only in the random access response window ra-ResponseWindow or the random access conflict resolution timer ra-ContentionResolutionTimer or the message B response window msgB - Monitor PDCCH only when ResponseWindow is running);

It should be noted that the MUSIM interval taking effect in the embodiment of this disclosure means that during the MUSIM interval, the MAC entity can perform at least one of the following:

2. Do not report the detection reference signal SRS;

4. Do not monitor the physical downlink control channel PDCCH and do not receive the downlink shared channel DL-SCH (this operation can be replaced by: only respond in the random access response window ra-ResponseWindow or the random access conflict resolution timer ra-ContentionResolutionTimer or message B PDCCH is monitored only when the window msgB-ResponseWindow is running.

Otherwise, the physical downlink control channel PDCCH is not monitored and the downlink shared channel DL-SCH is not received);

It should be noted that the UE can determine the activation status of the SCG based on the activation or deactivation SCG information received from the base station or MCG.

The invalidation of the MUSIM interval in the embodiment of the present disclosure means that the MUSIM interval does not affect the data transmission (or scheduling) process of the UE. The UE does not perform the operations performed when the above-mentioned MUSIM interval takes effect. During the MUSIM interval, the UE operates according to the unconfigured MUSIM interval. method for data transmission.

Scenario 2 MUSIM interval applies to cell group MCG or SCG

In scenario 2, the MUSIM interval is configured based on the cell group, and the MUSIM interval only affects the cell group in which it is located. Within the time limited by the MUSIM interval, the UE follows the operations that should be performed within the scheduling interval on all serving cells in the cell group where the MUSIM interval is located. In other words, the MUSIM interval is valid for all serving cells in the cell group where the MUSIM interval is located. Since the MUSIM interval only applies to MCG or SCG, how the UE requests the MUSIM interval and how the base station configures the MUSIM interval, and whether the MUSIM interval configured on the MCG after the SCG is activated or deactivated is valid is an issue that needs to be discussed.

Implementation 2-1 MUSIM interval request based on base station configuration

As shown in Figure 2, in step S201, the UE receives an RRC message from the base station. The RRC message may be an RRC reconfiguration message, and the message carries information indicating how the UE requests the MUSIM interval.

In step S202, after the UE requires a MUSIM interval and generates a MUSIM interval request message, it decides to send a MUSIM interval request message to the MCG or SCG according to the indication information in the RRC message.

The following is an example of a specific manner in which the RRC message carries information indicating how the UE requests the MUSIM interval:

Example 1: The RRC message carries an indication identifier (recorded as the first indication identifier), and the UE determines whether to send a MUSIM interval request message to the MCG or to the SCG according to the value of the indication identifier. For example, when the value of the indication identifier is a value corresponding to instructing the UE to send a MUSIM interval request message to the MCG, then after the UE needs a MUSIM interval and generates a MUSIM interval request message, it sends or transmits it through the MCG (i.e., requests to the MCG MUSIM interval); when the value of the indication identifier is the value corresponding to instructing the UE to send the MUSIM interval request message to the SCG, then after the UE needs the MUSIM interval and generates the MUSIM interval request message, it sends or transmits it through the SCG (that is, to the SCG). SCG request MUSIM interval). Optionally, the indication mark can also be set to a value that does not restrict the UE from sending the MUSIM interval request message to MCG or SCG. In this case, the UE can decide independently whether to send the MUSIM interval request message to MCG or to SCG. M USIM interval request message.

Example 2: The RRC message carries an indication identifier (recorded as the second indication identifier). The indication identifier is used to instruct the UE to send a MUSIM interval request message to the SCG. When the indication identifier appears or when the indication identifier The value of is the value corresponding to instructing the UE to send a MUSIM interval request message to the SCG. Then, after the UE needs a MUSIM interval and generates a MUSIM interval request message, it sends or transmits it through the SCG. Preferably, when the indication identifier does not appear or when the value of the identifier is a value that prohibits the UE from sending a MUSIM interval request message to the SCG, the UE, after requiring a MUSIM interval and generating a MUSIM interval request message, sends or transmission. Alternatively, when the indicator does not appear, the UE can independently decide whether to send a MUSIM interval request message to the MCG or to send a MUSIM interval request message to the SCG. SCG in this example can also be replaced with MCG and MCG with SCG. The resulting new example is also within the scope of the present disclosure.

Example 3: Indicate in the RRC message which cell group the UE can request periodic MUSIM intervals and/or aperiodic MUSIM intervals, or indicate whether the IE can request periodic MUSIM intervals and/or aperiodic MUSIMs from MCG or SCG. interval. In other words, the request for MUSIM interval in Example 1 and Example 2 may be replaced by requesting periodic MUSIM interval and/or aperiodic MUSIM interval.

In the embodiment of the present disclosure, the UE needs the MUSIM interval and generates the MUSIM interval request message means: if the UE is configured to provide MUSIM auxiliary information without leaving the RRC connection state, the UE has a preference on the MUSIM interval and the UE is configured After providing MUSIM assistance information without leaving the RRC connected state, a UE assistance information message containing the information element musim-GapPreferenceList used to indicate the configured MUSIM interval of the UE preference has not been transmitted, or the current musim-GapPreferenceList is different from the most recently transmitted UE assistance The musim-GapPreferenceList contained in the information message and the prohibition timer T for MUSIM auxiliary information reporting without leaving the RRC connection state for MUSIM purposes is not running, then the process of transmitting the UE auxiliary information message is initiated to provide the current musim-GapPreferenceList.

In addition, the MUSIM gap request message in the embodiment of the present disclosure refers to the UE assistance information message UEAssistanceInformation message including the current musim-GapPreferenceList. However, if the MUSIM interval request message is a request to release one or more MUSIM intervals, the UE assistance information message may not include musim-GapPreferenceList.

In the embodiment of the present disclosure, for the embodiment where the UE independently decides how to send the MUSIM interval request message, the UE may decide to send it through MCG (or SRB1) or SCG (or SRB3) according to the frequency information of network B (such as FR1 or FR2). The MUSIM request message.

In this disclosed embodiment, sending or transmitting through MCG means submitting it to the lower-layer entity corresponding to MCG (such as MCG RLC entity or MCG MAC entity), and sending or transmitting through SCG means submitting it to the lower-layer entity corresponding to SCG (such as SCG RLC entity). or SCG MAC entity).

In the embodiment of the present disclosure, the UE assistance information message (that is, the UEAssistanceInformation message) is used to indicate the UE assistance information to the network.

Embodiment 2-2 Predefined MUSIM interval request method

Allow MUSIM Interval Request messages to be transmitted on SRB3. Since whether the SCG is configured with SRB3 is optional, the UE can decide whether to send a MUSIM interval request message to the SCG based on whether SRB3 is configured.

As shown in Figure 3, it can be stipulated that in step S301, it is judged whether the base station has configured SRB3 for the UE through the RRC message. According to the judgment result, in step S302, when the base station configures SRB3 for the UE through the RRC message, the UE needs to After the MUSIM interval and generates the MUSIM interval request message, it is sent through SRB3; or when the base station configures SRB3 for the UE through the RRC message, the UE needs the MUSIM interval and generates the MUSIM interval request message, and then sends it through SRB3, but whether it is transmitted through SRB3 It is up to the UE to decide independently. For example, the UE decides to send the MUSIM interval request message to the corresponding cell group based on requesting the MCG or the SCG to configure the MUSIM interval for it. It can be specified that, for a MUSIM interval request message requesting the release of the MUSIM interval configured on the SCG, if SRB3 is configured, the MUSIM interval request message is sent through SRB3, otherwise it is sent through MCG.

In step S303, if SRB3 is not configured, the MUSIM interval request message can only be sent through the MCG. The MUSIM interval request message can carry indication information (the third indication identifier) to instruct the UE to request to configure the requested MUSIM interval in MCG or SCG related information. Specifically, if the UE requests the network to configure the requested MUSIM interval on the MCG or SCG, an indication identifier can be carried in the MUSIM interval request message for Information indicating whether the UE requests to configure the requested MUSIM interval on MCG or SCG. It can be stipulated that the indication mark is used to indicate requesting the MUSIM interval of the SCG or to instruct the network to configure the requested MUSIM interval in the SCG; in this case, if the indication mark appears, it means that the UE requests to configure the MUSIM interval. On the SCG, otherwise, it indicates a request to configure the MUSIM interval on the MCG or indicates that the UE has no preference. At this time, the base station can independently decide whether to configure the MUSIM interval on the SCG or the MCG. It may also be specified that the indication mark is used to indicate requesting the MUSIM interval of the MCG or to instruct the network to configure the requested MUSIM interval in the MCG; in this case, if the indication mark appears, it means that the UE requests the MUSIM interval of the MCG. Interval or request to configure the requested MUSIM interval on the MCG. Otherwise, it indicates a request for the MUSIM interval of the SCG or a request to configure the requested MUSIM interval on the SCG or indicates that the UE has no preference. At this time, the base station can decide independently whether to configure the MUSIM interval on the SCG. Or on the MCG. It can also be stipulated that according to the value of the indication identifier, it indicates whether to request the MCG MUSIM interval or the SCG MUSIM interval. If the value of the indication identifier is the first value, it means that the UE requests the MCG MUSIM interval. If the value of the indication identifier is The value is the second value, indicating that the UE requests the SCG MUSIM interval. Optionally, if the value of the indication flag is the third value or the indication flag does not appear, it indicates that the MUSIM interval requested by the UE can be configured in the MCG or SCG, the UE has no preference for this.

It should be noted that, in the embodiment of the present disclosure, requesting the SCG (or MCG) MUSIM interval refers to requesting the network to configure the requested MUSIM interval on the SCG (or MCG).

In the above-mentioned Embodiment 2-1 and Embodiment 2-2, if the UE requests MUSIM intervals from MCG and SCG respectively, the total number of MUSIM intervals requested on MCG and SCG cannot exceed the number of MUSIM intervals that the UE can request or configure. the maximum value.

If MCG and SCG respectively configure MUSIM intervals for UE, the total number of MUSIM intervals configured by them for UE cannot exceed the total number of MUSIM intervals allowed to be configured. MN and SN can negotiate their respective configurable MUSIM interval types through the Xn interface between them. and/or the number of various types of MUSIM intervals.

Embodiment 2-3 If the SCG is deactivated, the MUSIM interval configured on the MCG becomes invalid. If the SCG is activated, the MUSIM interval configured on the MCG and/or SCG takes effect.

In this embodiment, the MUSIM interval configured on the MCG can only be configured when the SCG has not been removed. Valid when activated. As shown in Figure 4, in step S401, the activation status of the SCG (that is, whether it is deactivated or activated) is judged. According to the judgment result, in step S402, when the SCG is deactivated, the SCG configured on the MCG The MUSIM interval becomes invalid; in step S403, when the SCG is activated, the MUSIM interval configured on the MCG and/or SCG takes effect.

This embodiment may be further limited to be only applicable to the case where MCG and SCG are on the same frequency.

Scenario 3 MUSIM interval applies to specific serving cells

In scenario three, the MUSIM interval is configured based on the cell, and the MUSIM interval only affects the cell in which it is located. Within the time limited by the MUSIM interval, the UE performs the operations that should be performed when the MUSIM interval is valid or invalid in the cell where the MUSIM interval is located. In this scenario, how the UE requests the MUSIM interval and/or how the UE requests activation or deactivation of the cell is a problem that needs to be solved.

Embodiment 3-1 The UE indicates in the MUSIM interval request message which cell or cells the network is requested to configure the MUSIM interval on.

A UE operating in carrier aggregation mode in network A, after requiring a MUSIM interval and generating a MUSIM interval request message, sends the MUSIM interval request message to network A, carrying indication information (denoted as the fourth indication) in the message. Identifier) is used to indicate in which cell or cells the requesting network configures the requested MUSIM interval for the UE or instructs the requesting network in which cell or cells the requested MUSIM interval is configured.

In one implementation, the information carried in the MUSIM interval request message is a bitmap. Each bit in the bitmap corresponds to each cell configured by the network for the UE. For example, the cell identifiers are in order from small to large. From left to right corresponds to each bitmap. The leftmost bit of the bitmap corresponds to SpCell, and the second bit from the left corresponds to the SCell with the smallest cell ID. It can be specified that a value of 1 (or 0) in the bitmap indicates that the UE requests the network to configure the requested MUSIM interval on the cell corresponding to this bit, or a value of 1 (or 0) in the bitmap indicates that the UE requests that the network does not correspond to this bit. Configure the requested MUSIM interval on the cell.

In one implementation, the MUSIM interval request message carries a cell list, instructing the UE to request cell information for configuring the MUSIM interval or instructing the UE to request cell information for which the MUSIM interval is not configured.

In the above embodiment, further, different MUSIM intervals can be configured on different cells, and the associated cell information can be indicated for each requested MUSIM interval, that is, the requesting network can indicate the requesting network for each requested MUSIM interval. In which cell or cells the MUSIM interval is configured.

In addition, for a UE that is in dual connectivity and carrier aggregation at the same time, Embodiment 3-1 and Embodiment 2-2 can be combined. If SRB3 is not configured or the MUSIM interval request message is sent through MCG, the UE can carry the MUSIM interval request message. An indicator indicating the cell group to indicate whether the requested MUSIM interval is requested to be configured on the MCG or SCG. In this case, the cell indicated by the fourth indication flag carried in the MUSIM request message is a cell in the cell group that is confirmed according to the cell group indication identification.

Embodiment 3-2 UE indicates the cell requesting deactivation in the UE assistance information message

When a UE operating in carrier aggregation mode in Network A requests Network A to deactivate one or more cells for MUSIM purposes (such as the need to establish an RRC connection with Network B), the UE sends a request message (such as UE assistance information) to Network A. message), the message carries the cell information requested for deactivation.

Specifically, in one implementation, the cell information carrying the deactivation request in the message is a bitmap, and each bit in the bitmap corresponds to each cell configured by the base station for the UE. For example, the bits in the bitmap correspond to each bit in the bitmap from left to right in ascending order of cell identifiers. The leftmost bit of the bitmap corresponds to the SCell with the smallest cell identifier (except SpCell), and the second bit from the left corresponds to the SCell with the second smallest cell identifier. . It can be specified that a value of 1 (or 0) in the bitmap indicates that the UE requests activation of the corresponding cell, or a value of 1 (or 0) in the bitmap indicates that the UE requests to deactivate the corresponding cell.

In one implementation, the cell information carried in the message requesting deactivation is a cell list, and the UE includes the cell identity requesting deactivation in the list and/or requests activation of other configured but not included in the list. The cell in the list, or the UE includes the cell identity requested for activation in the list and/or requests the deactivation of other cells that have been configured but are not included in the list.

In this embodiment, the message may also carry cell information requesting to remain activated to instruct the network to deactivate other cells except the cell indicated in the RRC message. Combine the above two After the cell requesting deactivation is replaced by the cell requesting activation in the embodiment, it is applicable to the case where the message carries information about the cell requesting to remain activated.

Embodiment 3-3 UE indicates the cell requesting deactivation in MAC CE

When a UE operating in carrier aggregation mode in network A requests network A to deactivate one or more cells for MUSIM purposes (for example, it needs to establish an RRC connection with network B), the UE sends a media access control (MAC) control to network A. Element (CE), which carries the cell information requested for deactivation in the MAC CE. In one implementation, the MAC CE contains a bitmap, and each bit in the bitmap corresponds to each cell configured by the network for the UE. For example, the bits in the bitmap correspond to each bit in the bitmap from left to right in ascending order of cell identifiers. The leftmost bit of the bitmap corresponds to the SCell with the smallest cell identifier (except SpCell), and the second bit from the left corresponds to the SCell with the second smallest cell identifier. . It can be specified that a value of 1 (or 0) in the bitmap indicates that the UE requests activation of the corresponding cell, or a value of 1 (or 0) in the bitmap indicates that the UE requests to deactivate the corresponding cell.

In one implementation, the MAC CE contains one or more cell identities that the UE requests to deactivate or activate.

In this embodiment, the cell information carrying the deactivation request in the MAC CE can also be replaced with the cell information carrying the activation request in the MAC CE to instruct the network to deactivate other cells except the cell indicated in the MAC CE. After replacing the cell requested for deactivation in the above two embodiments with the cell requested for activation, it is applicable to the case where the MAC CE carries the information of the cell requested for activation.
