Capability coordination between wireless devices

Abstract

For multi-subscriber identity module (multi-SIM) wireless devices, a wireless device can connect to multiple networks simultaneously. This can require coordination of wireless device capabilities (capability coordination). A wireless device that is roaming can connect to multiple networks using different slices, which can also require capability coordination. Video, image, and audio for professional applications (VIAPA) devices can require a wireless device to receive data services from one network (e.g., a non-public network (NPN)) and simultaneously receive paging and data services from another network (e.g., a public land mobile network (PLMN)), which can also require wireless device capability coordination.

[0018] Certain features are described using examples of Fifth Generation (5G) wireless protocols. However, the applicability of the disclosed technology is not limited to 5G wireless systems.

[0019] The following uses headings below for clarity of expression and is not intended to limit the applicability of the subject matter in the various disclosed embodiments.

[0020] For multi-SIM (multi-SIM) wireless devices, a wireless device can connect to multiple networks simultaneously. This can require coordination of wireless device capabilities (capability coordination). As used herein, a “wireless device” can be any type of wireless device, including a user equipment, a mobile station, a smartphone, a tablet device, a laptop device, or any other wireless device. The above terms can be used interchangeably. Multi-SIM can include multiple SIMs / USIMs (Universal Mobile Telecommunications System Subscriber SIMs), soft SIMs, embedded SIMs, or virtual SIMs. A virtual SIM card has a subscription downloaded from a network.

[0021] A wireless device that is roaming can connect to multiple networks using different slices, which can also require capability coordination.

[0022] Video, Imaging and Audio for Professional Application (VIAPA) devices can require a wireless device to receive data services from one network (e.g., a non-public network (NPN)) and simultaneously receive paging and data services from another network (e.g., a public land mobile network (PLMN)), which can also require wireless device capability coordination.

[0023] In some standards, radio access capability signaling (RACS) defines radio access capabilities as pre-defined or network-defined wireless device capabilities via an identifier.

[0024] In some cases, a multi-SIM wireless device can simultaneously connect to multiple networks:

[0025] 1) When a first SIM (SIM1) is in a connected state with a first network, a paging message is received via a second SIM (SIM2). This case can be accommodated via time-division multiplexing (TDM). For example, by reserving a scheduling gap for SIM2, so that there is no simultaneous connection to both networks that requires coordination. For wireless devices with dual receivers, this solution will impact the performance of SIM1 by reserving a scheduling gap with the paging cycle. Another solution for dual receiver wireless devices is to reserve part of the radio frequency / physical layer (RF / PHY) resources for receiving paging messages.

[0026] 2) Short dual connectivity state or dual control plan connectivity state. For example, if SIM1 is in a connected state and SIM2 must perform a mobility update, such as a periodic registration, moving to a new registration area, or responding to a page. For these cases, the wireless device can require capability coordination during the short dual connectivity state.

[0027] 3) Long dual connectivity state or dual user plan connectivity state. For example, a wireless device can have a voice call on SIM1 and another data service on SIM2. For this case, the wireless device can require capability coordination.

[0028] As an enhancement on slices, some systems can need to enable a roaming wireless device to access network slices from more than one visited public lane mobile network (VPLMN) simultaneously. In this way, the wireless device can be connected to two networks at the same time, which has similar challenges as multi-SIM wireless devices and can require wireless device capability coordination.

[0029] VIAPA (Video, Image, and Audio for Professional Applications) can require a wireless device to receive data services from one network (e.g., NPN) and simultaneously receive paging and data services from another network (e.g., PLMN). Similar issues to multi-SIM regarding UE capability coordination will then be discussed.

[0030] In the following description, solutions for multi-SIM wireless devices are described, but can also be applied to the roaming wireless device and VIAPA cases described above.

[0031] Capability coordination for receiving paging messages

[0032] For dual-receiver wireless devices, to use SIM2 to receive paging messages while SIM1 is connected to a network, the wireless device can split part of the RF / PHY resources to detect paging on SIM2. There are two options:

[0033] Option A: The wireless device always reserves part of the RF / PHY resources for receiving paging messages. For this option, the wireless device reports the maximum capability of the wireless device (excluding the reserved part) during registration in multi-SIM mode. The wireless device can report its maximum capability during registration in single-SIM mode.

[0034] Option B: Only for the paging gap, part of the RF / PHY resources is reserved for receiving paging messages. The wireless device will send to the network of SIM1 the location of the time gap for checking paging of SIM2. For example, when a SIM2 paging message occurs, the wireless device can be using all PHY / RF resources for SIM1 for high quality of service procedures. To accommodate the required gap for SIM2 for the paging message, the wireless device will inform SIM1 of the reduced wireless device capability and the SIM2 paging gap. Network A connected to SIM1 will take into account the reduced capability when allocating resources.

[0035] For dual-receiver wireless devices, the wireless device can reserve part of the RF / PHY resources for paging detection. The reserved part can be permanently reserved, or can be reserved only for the required paging gap.

[0036] For both options, there are two sets of wireless device capabilities (also referred to herein as “capability sets”):

[0037] 1) Full set of wireless device capabilities, capable of being used in single SIM mode for option A or option B, or in multi-SIM mode for option B for duration outside of paging gap. The full set of capabilities indicates the maximum capability of the wireless device. For example, this can include wireless device parameters, band parameters, band combination parameters, per band parameters under band combination, or carrier component (CC) parameters.

[0038] 2) Reduced set of wireless device capabilities, capable of being used in multi-SIM mode for option A, or in multi-SIM mode for option B in paging gap. The reduced set of capabilities is one or more of the following parameters: band combination parameters, per band parameters under band combination, or CC parameters.

[0039] Full capability set and reduced capability set

[0040] In some example embodiments, the wireless device sends or reports multiple sets of wireless device capabilities to the network. For example, the wireless device can send the full set of wireless device capabilities and the reduced set of device capabilities (the reduced set of device capabilities is equal to the full set of device capabilities minus the RF / PHY resources reserved for paging detection). Multiple reduced sets of capabilities can be sent. Figure 1 A schematic comparison of the full set of capabilities and the reduced set of capabilities is depicted.

[0041] The wireless device should indicate the correct wireless device capabilities to the network per specific time. For option A, considering that the wireless device will not frequently change its mode of operation, it can indicate the wireless device capabilities during registration based on the wireless device mode of operation (single SIM or multi-SIM), and when the wireless device capabilities change, the UE can trigger the registration procedure. For option B, when the wireless device operates in multi-SIM mode, the wireless device can indicate the two sets of capabilities to the network using the following methods.

[0042] Solution 1: The wireless device can report both sets of capabilities during the registration procedure. The sets of capabilities can be via capability information or capability identifier (ID) as radio access capability signaling (RACS). A delta configuration indicating the change between the sets of capabilities for the reduced set of capabilities can be adopted. The core network (CN) can indicate both sets of capabilities to the base station (e.g., next generation node B (gNB)), and the base station can further determine which capability to adopt based on the current timing.

[0043] Figure 2 An example of the procedure of solution 1 above is depicted. At 210, the wireless device indicates multi-SIM and / or dual radio in a non-access stratum (NAS) message (e.g., registration or radio resource control (RRC) message, such as Msg5). At 220, the CN indicates to the base station that wireless device capabilities are requested, the CN can also indicate the multi-SIM and / or dual radio status to the radio access network (RAN). At 330, the base station sends a wireless device capability request message to the access stratum (AS), and multiple capability sets can be required. At 240, the wireless device sends multiple capability sets (e.g., wireless device capability set 1 / 2) as defined above in a wireless device capability information message, including a full capability set and a reduced wireless device capability set for paging detection. Note: considering the message size, the network can ask for the capability one by one, the wireless device can indicate its support of reduced capability in the first wireless device capability information, or the RACS can include a wireless device capability ID in the registration and indicate which one is the reduced wireless device capability. At 250, the wireless device completes the registration procedure on SIM1. At 260, the wireless device completes the registration at SIM2 using a similar procedure as the procedure with SIM1. At 255, the wireless device establishes a data radio bearer (DRB) on SIM1 and starts data transmission. At 270, the UE detects a page on SIM2 and sends assistance information for paging detection, including one or more of time domain information of periodic paging detection gap, paging detection frequency, SCS / bandwidth of paging detection frequency band. At 280, the SIM1 base station takes both the paging assistance information and the reduced wireless device capability into account for radio resource management (RRM).

[0044] Solution 2: The wireless device reports the full capability set during the registration procedure and then reports the reduced capability through assistance information. It can send some parameters to limit the maximum value of some wireless device capability parameters, such as the maximum number of component carriers (CC).

[0045] Figure 3An example of the procedure of solution 2 is depicted. At 310, 320, 330, 340, 350, and 360, the wireless device completes the registration procedure on SIM1 and SIM2. At 355, the wireless device establishes DRB on SIM1 and starts data transmission. At 370, the wireless device detects a page on SIM2 and sends assistance information for page detection including time domain information on periodic page detection gap and reduced wireless device capability related information (reduced value or maximum limit). At 380, the SIM1 base station takes the page assistance information into account for RRM.

[0046] The reduced capability set can be sent by capability information or by assistance information. In solution 1, the wireless device reports two wireless device capability sets during the registration procedure, which can be as RACS or wireless device capability ID. Incremental configuration for reduced capability can be adopted. In solution, the wireless device reports the full capability set during the registration procedure and then reports the reduced capability by assistance information.

[0047] Both solution 1 and solution 2 can be used for page detection. Solution 2 is dynamic and can depend on how many capability parameters are affected. The wireless device can resend the assistance information once the wireless device returns from idle state to connected state. Solution 1 would be a semi-static solution, where the wireless device can report the reduced capability for page detection during the registration procedure, which will also be stored in the CN.

[0048] The determination of whether to use solution 1 or solution 2 can depend on how many capability parameters are affected. For wireless device capability, baseband and RF capability is mainly included in band combination. If the wireless device needs to detect a page on a certain band, this will affect the capability of the band combination that does not include the page detection band. For the band combination that includes the page detection band, the affected capability should be determined. Figure 4 Six band combination capability items are shown: BC capability items 1-6. Figure 4 An example is shown, where the full capability set includes band combinations (BC) BC1 (B+A) and BC2 (B+C), then if the wireless device on SIM2 uses band A, in the reduced capability set, for BC1 (B+A), detecting a page on band A will affect band combination capability items 1-6, while for BC2 (B+C), it will only affect band combination capability items 1-4.

[0049] Impacted band combination capabilities

[0050] The impacted capability items are different for BCs with and without the paging detection band. If the impacted capabilities are different, the network A can be indicated the paging detection band of SIM2 as the paging assistance information and the network can further determine which BC capabilities are impacted.

[0051] Capabilities employed by solution 1

[0052] In the solution 1 example, the wireless device can include reduced capabilities where the whole band is impacted by the paging detection in the multi-SIM mode. Once the wireless device reports the dedicated paging detection band of SIM2, i.e. the BC capabilities (e.g., BC capability items 5A / 6A and 5D / 6D in Table 1) that are not impacted by the paging detection, the network can employ the capabilities in the full capability set for the BCs that do not include the paging detection band. Figure 5 For solution 1, it is assumed that all bands are impacted by the paging detection band in the multi-SIM mode, the wireless device can include reduced capabilities and the network can determine the final capabilities by considering all the full capability set / reduced capability set / paging detection band.

[0053] For solution 2, in the assistance information, the UE can include the maximum values of the impacted capabilities, e.g., BC capability items 1-6, then for the BCs with the paging detection band, all the maximum values should be considered, but for the BCs without the paging detection band, it can only include the maximum values of BC capability items 1-4. If the impacted capabilities are different for the BCs with and without the paging detection band, the network 1 is indicated the paging detection band of SIM2. Then, the network 1 can further determine which BC capabilities are impacted. The paging detection band information is also beneficial for the network 1's radio resource management. In addition to the BC capabilities, there are also UE level capabilities and band capabilities, for the band capabilities, the same logic as the BC capabilities can be employed.

[0054] Capability coordination for dual connectivity state

[0055] For the paging detection on SIM2, the receive only capability on SIM1 is impacted, but for the dual connectivity state (SMI1 and SIM2), both the receive and transmit capabilities are impacted. There are two possible scenarios: a) dual receive and single transmit, b) dual receive and dual transmit. For the dual receive and single transmit case, the wireless device transmits in time division multiplexing (TDM) mode on the two networks. Therefore, the requirement for the capability coordination is mainly from the receive side, which is similar to the paging detection. For the dual receive and dual transmit case, the wireless device can transmit simultaneously. Therefore, in addition to the receive coordination, the transmit coordination is also needed. For the transmit capability coordination, multiple wireless device capability sets can be needed.

[0056] Multiple wireless device capability sets

[0057] Figure 6 An example of dividing wireless device capabilities into four categories is shown:

[0058] Part 1: Capabilities that are not affected by dual connectivity status or paging detection on other SIM cards;

[0059] Part 2: Capabilities that are only affected when the wireless device needs to receive simultaneously from two SIM cards;

[0060] Part 3: Capabilities that are only affected when the wireless device needs to transmit simultaneously from two cards;

[0061] Part 4: Other capabilities that are affected by both simultaneous reception and simultaneous transmission.

[0062] For a wireless device with SIM1 / SIM2, for a paging occasion (PO) for SIM2, SIM1 can only use reduced part 2 / 4 of the reduced capabilities when SIM2 is in idle / inactive state. For other parts (part 1 / 3), SIM1 can use the capabilities identified in the full capability set. When SIM2 needs to enter connected state, the wireless device will consider the full reduced capabilities. Dual connectivity status wireless device capability coordination can require multiple wireless device capability sets. For example, a full UE capability set and a reduced UE capability set, where the reduced capabilities are adopted in dual connectivity status mode.

[0063] Similar to the capability coordination for paging detection, the following also applies to dual connectivity status.

[0064] The reduced capability set can be sent through the wireless device capability information or through assistance information. Two solutions include:

[0065] Solution 1: The wireless device reports multiple capability sets during the registration procedure. The multiple capability sets can be sent via the capability information or identified with capability identifiers (such as using RACS). An incremental configuration for the reduced capabilities can be adopted. For example, the incremental configuration can indicate the difference in capabilities.

[0066] Solution 2: The wireless device reports the full capability set during the registration procedure and then reports the reduced capabilities via assistance information.

[0067] For BCs with and without SIM2 connected bands, the affected capability items can be different.

[0068] If the impacted capabilities are different, the connected band information of SIM2 can also be indicated to network 1, then network 1 is able to further determine which BC capabilities are impacted. In addition, the connected band information can also be beneficial to the radio resource management of network 1.

[0069] Procedure for solution 1

[0070] Figure 7 An example procedure 700 based on the above solution 1 is shown.

[0071] At 710, the wireless device indicates the multi-SIM and / or dual radio status in a NAS message. For example, a registration or RRC message, such as Msg5.

[0072] At 720, the core node indicates to the base station (e.g., gNB) to obtain the wireless device capabilities. The CN is also able to indicate the multi-SIM or dual radio status to the RAN.

[0073] At 730, the RAN sends a wireless device capability request message to the RAN. This message can indicate that multiple capability sets are needed.

[0074] At 740, the wireless device sends multiple capability sets. For example, in the capability information, capability set 1 / 2 as described above. Msg.1 is the full capability set, Msg.2 is the reduced capability set for dual connectivity status. Considering the message size, the network can request this capability one by one, the UE can indicate its support of reduced capability in the first UE capability information. Or the RACS can include two wireless device capability identifiers in the registration and indicate which one is the reduced UE capability.

[0075] At 750, the wireless device completes the registration procedure for SIM1.

[0076] At 760, the wireless device uses a similar procedure as SIM1 to complete the registration procedure for SIM2 and enters the inactive / idle state.

[0077] At 755, the wireless device establishes a DRB on SIM1 and starts data transmission using the wireless device capability 1.

[0078] At 770, the wireless device establishes a connection on SIM2 and internally negotiates the capability with SIM1.

[0079] At 780, the wireless device employs the reduced capability set on network 1 of SIM1.

[0080] At 785, the wireless device can wait for a response.

[0081] At 790, the UE establishes a connection with the network and indicates the reduced capability to the network.

[0082] At 792, SIM2 enters the idle / inactive state.

[0083] At 794, the wireless device indicates to network 1 to return to the full set of capabilities.

[0084] Multiple reduced capability sets

[0085] In the above example, only one reduced capability set is used, but as mentioned above, there are two types of dual connectivity state:

[0086] Type 1: short-lived dual connectivity state. For example, SIM1 is in connected state and SIM2 has to do a mobility update (e.g. periodic registration, moving to a new registration area or responding to a page). In this case, the wireless device needs capability coordination during the short-lived dual connectivity state.

[0087] Type 2: long-lived dual connectivity state: for example, the wireless device can have a voice call on SIM1 and can have some other data service on SIM2. In this case, the wireless device can need capability coordination.

[0088] Generally, Type 1 can be considered as a control plane dual connectivity state, while the second type can be considered as a user plane dual connectivity state. Different capabilities can be employed for different dual connectivity state types.

[0089] For short-lived dual connectivity state using SIM2 for control plane only, reduced capability set 1 can be employed, while for dual connectivity state with data transmission, SIM2 can need to occupy more RF / Phy resources, then reduced capability set 2 can be employed. The wireless device needs to indicate to the network which capability set is preferred based on the services of the two SIMs.

[0090] For solution 2, in order to indicate to the network which capability set is preferred, the wireless device can directly indicate the reduced capability. For solution 1, the wireless device can give the preferred capability identifier (if RACS is employed, it will also impact SA and RAN 3 for this solution) or reduced capability set index.

[0091] Solution 1 is semi-static and can be stored in the CN, while solution 2 is dynamic and will be released in idle state. These two solutions can also be combined for different scenarios and needs. For example, when the wireless device enters dual user plane (UP) connectivity, the network can take reduced capability set 2 as baseline, and then the wireless device can further send assistance information to limit the maximum number based on reduced capability set 2.

[0092] Figure 8 Examples of full capability set and multiple reduced capability sets are depicted.

[0093] To better understand the multiple wireless device capability schemes, the typical procedure for solution 1 is described below in Figure 9 In this example, the wireless device reports four reduced capability sets:

[0094] Capability Set 1: Full capability set

[0095] Capability Set 2: Reduced capability set for paging detection

[0096] Capability Set 3: Reduced capability for control plane (CP) dual connectivity state

[0097] Capability Set 4: Reduced capability for UP dual connectivity state.

[0098] Note: Capability Set 2 can be part of Capability Set 3.

[0099] In Figure 9 At 910, the wireless device indicates the multiple SIM and / or dual wireless mode in a NAS message (e.g., registration or RRC message (e.g., Msg5)) to the CN.

[0100] At 920, the CN indicates to the base station (e.g., gNB) to obtain the wireless device capability. The CN can also indicate the multiple SIM or dual wireless state to the RAN.

[0101] At 930, the RAN sends a wireless device capability request message to the RAN. This message can request multiple capability sets.

[0102] At 940, the wireless device sends multiple wireless device capability sets in a wireless device capability information message, such as the wireless device capability sets 1 / 2 / 3 / 4 defined above. Capability Set 1 is the full wireless device capability set, 2 / 3 / 4 are reduced wireless device capability sets for dual connectivity state. The network can request capability sets one by one considering the message size, the wireless device can indicate its support of reduced capability in the first wireless device capability information, or RACS can be used in the registration message to include 4 wireless device capability identifiers and indicate which one is the reduced capability set.

[0103] At 950, the wireless device completes the registration procedure on SIM1.

[0104] At 960, the wireless device uses a similar procedure as SIM1 to complete the registration procedure for SIM2.

[0105] At 970, the wireless device detects a page on SIM2 and sends assistance information for the page detection including time domain information for a periodic page detection gap, a page detection frequency, and / or a preferred set of wireless device capabilities.

[0106] At 980, the SIM1 base station (e.g., gNB) considers the page assistance information and reduced capabilities for RRM.

[0107] At 990, the wireless device establishes a control plane connection with SIM2 and can internally perform a capability negotiation with SIM1.

[0108] At 992, the wireless device indicates to network 1 of SIM1 to employ the reduced set of capabilities. The wireless device can wait for a response.

[0109] At 994, the wireless device establishes a dual control plane connection with network 2 and indicates the reduced set of capabilities.

[0110] At 995, the wireless device establishes a UP connection on SIM2 and can internally perform a wireless device capability negotiation with SIM1.

[0111] At 997, the wireless device indicates to network 1 of SIM1 to employ the reduced wireless device capability 4. The wireless device can wait for a response.

[0112] At 999, the wireless device establishes a dual UP connection with network 2 and indicates the reduced capabilities.

[0113] Figure 10 An example of a method 1000 for wireless communication is shown. At 1010, in some embodiments of the disclosed technology, the method includes determining, at a wireless device, one or more sets of user equipment (UE) capabilities associated with the wireless device based on an operating condition. At 1020, the method includes transmitting, from the wireless device to a network node, the one or more sets of UE capabilities in a message.

[0114] Figure 11 Another example of a method 1100 for wireless communication is shown. At 1110, in some embodiments of the disclosed technology, the method includes receiving, at a network node from a wireless device, one or more sets of user equipment (UE) capabilities associated with the wireless device based on an operating condition. At 1120, the method includes receiving, at the network node from the wireless device, assistance information related to a selected set of UE capabilities from the one or more sets of UE capabilities. At 1130, the method includes determining, at the network node, a final adopted set of UE capabilities to be allocated to the wireless device based on the selected set of UE capabilities and the one or more sets of UE capabilities. At 1140, the method includes transmitting, by the network node to the wireless device, the final adopted set of UE capabilities.

[0115] Figure 12 An example of a wireless communication system 1200 is shown in which techniques in accordance with one or more embodiments of the present technology can be applied. The wireless communication system 1200 can include one or more base stations (BSs) 1205a, 1205b, one or more wireless devices 1210a, 1210b, 1210c, 1210d, and a core network 1225. The base stations 1205a, 1205b can provide wireless service to the wireless devices 1210a, 1210b, 1210c, and 1210d in one or more wireless sectors. In some implementations, the base stations 1205a, 1205b include directional antennas to produce two or more directional beams to provide wireless coverage in different sectors. The base stations 1205a, 1205b can communicate directly with each other wirelessly or via wired interfaces, including direct wired interfaces, wired networks, or the Internet.

[0116] The core network 1225 can communicate with the one or more base stations 1205a, 1205b. The core network 1225 provides connectivity with other wireless communication systems and wired communication systems. The core network can include one or more service subscription databases to store information related to subscribed wireless devices 1210a, 1210b, 1210c, and 1210d. The first base station 1205a can provide wireless service based on a first wireless access technology, while the second base station 1205b can provide wireless service based on a second wireless access technology. The base stations 1205a and 1205b can be co-located or can be installed on-site separately depending on the deployment scenario. The wireless devices 1210a, 1210b, 1210c, and 1210d can support multiple different wireless access technologies.

In some embodiments, at least some of the disclosed technologies, modules or functions are implemented using the wireless station 1305. In some embodiments, the wireless station 1305 can be configured to perform the methods described in this document.

[0118] UE capability reporting

[0119] A UE can report single carrier capability outside of a network requested frequency band list. The UE sends a UE capability enquiry message (UECapabilityEnquiry) to the network and the network replies with UE capability information (UECapabilityInformation).

[0120] The UE capability enquiry message includes a frequencyBandListFilter parameter. In the UECapabilitylnformation message, only the BC capabilities (including single CC capabilities) of those bands included in the frequencyBandListFilter are included. This results in the UE being unable to report the single CC capabilities for bands supported by the UE but not included in the frequencyBandListFilter. This raises some issues in general. These issues relate to whether the network is able to switch to a supported band without any BC capabilities (including single CC capabilities). If there is no single CC capability, the network is unable to determine the action on a band included but not included in the frequencyBandListFilter. For handover, if the network attempts to handover to a band supported by the UE but without any BC capabilities, the network has to first acquire the relevant capabilities, which increases the handover delay. Unless the network puts all potential target bands into the frequencyBandListFilter in the preceding UE capability procedure, this will significantly increase the signalling overhead. To address this issue, the UE can report the single CC capabilities for each supported band, which is not affected by the frequencyBandListFilter. For CA / DC capabilities, the band is included in the frequencyBandListFilter.

[0121] Feature overview
