Description

Technical Field

[0002] Wireless communication technology is pushing the world towards an increasingly interconnected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between user devices and radio access network nodes (including but not limited to base stations). The next-generation network is expected to provide high-speed, low-latency and ultra-reliable communication capabilities and meet the requirements of different industries and users.

[0003] For the new generation of mobile communication technology, user equipment (UE) (e.g., smart phone) can reside on more than one network (e.g., network A and network B). The UE may need to schedule intervals with network A to perform some signaling transmission and reception (Tx / Rx) on network B. There may be some problems / issues associated with scheduling interval coordination.

[0024] The present disclosure describes methods and apparatus for scheduling interval coordination.

[0025] The new generation (NG) mobile communication system is pushing the world towards an increasingly interconnected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between user equipment and radio access network nodes (including but not limited to base stations). The new generation network is expected to provide high-speed, low-latency and ultra-reliable communication capabilities and meet the requirements of different industries and users.

[0026] For the new generation of mobile communication technology, a user equipment (UE) (e.g., a smart phone) may reside on more than one network (e.g., network A and network B). For example, the UE may need to schedule an interval with network A to perform some signaling transmission and reception (Tx / Rx) on network B, for example. There may be some problems associated with scheduling interval coordination. The present disclosure may solve at least one of the problems associated with the existing system and describes various embodiments for scheduling interval coordination, thereby improving the performance of wireless communication.

[0027] In one or more scenarios, a user equipment (UE) may be connected to more than one network simultaneously. In the present disclosure, various embodiments for scheduling interval coordination when the UE is operating in a multi-radio dual connectivity (MR-DC) structure are described as non-limiting examples. In other cases, the various embodiments in the present disclosure may also be applicable when the UE can operate in any dual connectivity structure (e.g., multiple subscriber identity modules (Multi-SIM, multi-SIM) (or multiple universal subscriber identity modules (Multi-USIM, multi-USIM))).

[0028] In some embodiments, under the MR-DC structure, the UE can be connected to two different radio access network nodes at the same time, for example, one network node provides new radio (NR) access, and the other network node provides 4G (or LTE) access.

[0029] In some embodiments, under the MR-DC structure, one of the multiple network nodes serving the UE acts as a master node (MN), which provides primary wireless resources via a master cell group (MCG); and another network node among the multiple network nodes serving the UE acts as a secondary node (SN), which provides additional wireless resources to the UE via a secondary cell group (SCG).

[0030] Figure 1A A wireless communication system 100 is shown that includes more than one radio network node (118 and 119) and one or more user equipments (UEs) (110, 111, and 112).

[0031] The radio network nodes (118 and 119) may include a network base station, which may be a node B (NB) (e.g., eNB or gNB) in the context of mobile telecommunications. Each of the UEs (110, 111, and / or 112) may wirelessly communicate with the radio network nodes (118 and / or 119) via one or more radio channels 115. For example, the first UE 110 may wirelessly communicate with the first network node 118 via a channel including multiple radio channels during a specific time period; during another time period or at the same time, the first UE 110 may wirelessly communicate with the second network node 119 via a channel including multiple radio channels.

[0032] In some embodiments, idle (or inactive) state signaling may be received at periodic intervals or aperiodic intervals. Figure 1BIn the MUSIM (Multi-USIM) scheduling interval request and configuration process in, the UE (191) can send the MUSIM scheduling interval to the network node (192) in the UE assistance information, as described below: in step 161, the UE sends UE assistance information (UE assistance information, UAI) about the MUSIM interval to the network; in step 162, the network sends a reconfiguration message including the MUSIM interval to the UE; and / or in step 163, the UE sends a reconfiguration completion message to the network. In some embodiments, the UE (191) may include a first subscriber identity module (first subscriber identity module, SIM1) access stratum (access stratum, AS); and / or the network node (192) may include SIM1gNB A. In the above example, the scheduling interval granularity is for each UE, and the coordination between the MCG and the SCG is not described.

[0033] The present disclosure describes various embodiments for scheduling interval coordination. For example, some embodiments may describe how to receive idle / inactive state signaling at another network (eg, network B) when a UE is working with one network (eg, network A) in an MR-DC structure.

[0064] The present disclosure describes various exemplary embodiments for scheduling interval coordination, which are used as examples and do not impose any limitations on the present disclosure.

Specifically, the non-limiting examples address various issues, including: which node (UE or network) determines the scheduling interval granularity (e.g., per UE interval, per FR interval, per CG interval, per CC interval), what is the interaction between MN and SN for each scheduling interval granularity and what is the network configuration for the scheduling interval of each granularity; and / or how UE indicates relevant capabilities.

[0065] Embodiments for determining scheduling interval granularity

[0066] Various embodiments in the present disclosure describe which node determines the scheduling interval granularity (e.g., per UE interval, per FR interval, per CG interval, per CC interval), whether it is the UE or the network.

[0067] In one embodiment, the UE may determine the scheduling interval granularity and indicate the scheduling interval granularity to the network.

[0068] When the scheduling interval granularity is a per-UE interval, the UE may indicate the per-UE granularity.In some embodiments, for MR-DC, the interval is reserved for both MCG and SCG, and also reserved for both FR1 and FR2.

[0069] When the scheduling interval granularity is per FR interval, the UE needs to indicate the FR range, i.e., FR1 or FR2. In some embodiments, for MR-DC, the interval is reserved for FR1 or FR2, which means that the interval is reserved only on serving cells on the corresponding FR.

[0070] When the scheduling interval granularity is per CG interval, the UE can indicate a specific CG, i.e., SCG or MCG. In some embodiments, for MR-DC, the interval is reserved for MCG or SCG, which means that the interval is reserved only on the serving cell on the corresponding CG.

[0071] When the scheduling interval granularity is per CC interval, the UE may indicate the CC index.

[0072] In some embodiments, as an example of a combination of more than two types of the above interval granularities, the UE may indicate that the scheduling interval granularity is per CG per FR interval.

[0073] In some implementations, the UE may indicate the granularity to the network in the assistance information.

[0074] In some embodiments, for the SCG case (interval is reserved only at the SCG), the UE may send the UAI directly to the SN via SRB3, e.g. Figure 6 In step 601a: the UE sends the UAI with the interval request directly to the SN via SRB3.

[0075] For example, the UE may indicate the scheduling interval type in the UAI as follows:

[0076] SchedulingGapAssistanceInfo (scheduling gap assistance information): = SEQUENCE (sequence)

[0077] {

[0078] schedulinggapPref (Scheduling Gap Preference) SchedulingGapPreferenceList (Scheduling Gap Preference List)

[0079] schedulinggapGranylarity (scheduling gap granularity)ENUMERATED (enumeration) {perUE,perFR1,per FR2,MCG,SCG,per CC} ({per UE,per FR1,per FR2,MCG,SCG,per CC})OPTIONAL (optional),

[0080] ccIndex(CC index)CCIndex(CC index)OPTIONAL(optional)

[0081] }

[0082] SchedulingGapPreferenceList::=SEQUENCE(SIZE(1..3)) OFSchedulingGapPrefInfo(sequence of scheduling gap preference information(size(1..3)))

[0083] SchedulingGapPrefInfo (scheduling gap preference information)::=SEQUENCE{

[0084] SchedulingStarting-SFN-AndSubframe SchedulingStarting-SFN-AndSubframe (Scheduling Starting-SFN (System frame number, system frame number)-and subframe Scheduling Starting-SFN-and Subframe)

[0085] OPTIONAL,

[0086] SchedulingGapLength (scheduling interval length) ENUMERATED {ms3, ms4, ms6, ms10, ms20},

[0087] SchedulingGapRepetitionAndOffset (scheduling gap repetition and offset) CHOICE (select) {

[0088] ms20 INTEGER(integer)(0..19),

[0089] ms40 INTEGER(0..39),...}OPTIONAL(optional)}

[0090] For another example, the UE may indicate the interval granularity of each interval. For example, the UE indicates the scheduling interval granularity of each interval in the UAI as shown below:

[0091]

[0092]

[0093] In another embodiment, the network may determine the scheduling interval granularity (e.g., per UE interval, per FR interval, per CG interval, per CC interval). In some implementations, the network determines the scheduling interval granularity based on UE assistance information. The assistance information may include at least one of the following types of information.

[0094] One type of information may be frequency domain related information, which includes at least one of the following items: frequency band information, affected center frequency and bandwidth, frequency range information (eg, FR1 or FR2).

[0095] Another type of information may indicate physical downlink shared channel (PDSCH) configuration information on the relevant frequency band, such as multiple input multiple output (MIMO) layers and / or modulation orders.

[0096] Another type of information may include at least one of the following: allowed / affected band combination information, feature set combination information, and feature set entry information, etc. In this way, the network can determine which feature set entry of which BC can be adopted, and further determine which type of interval can be adopted.

[0097] In some embodiments, for the case where the UE determines the granularity in the previous embodiments, the network can also change the granularity, for example, changing the per CG interval or per FR interval to a per UE interval, or changing the per CC interval to a per CG interval or a per UE interval.

[0098] In some implementations, the UE indicates auxiliary information for determining the scheduling interval granularity as follows:

[0099] SchedulingGapAssistanceInfo:=

[0100] {

[0101] BandInfo (band information) EARFCN (Enhanced Absolute Radio Frequency Channel Number, enhanced absolute radio frequency channel number) or ARFCN (absolute radio frequency channel number, absolute radio frequency channel number) Optional (optional)

[0102] AffectedBandwidth (affected bandwidth) bandwidth (bandwidth) Optional (optional)

[0103] schedulinggapPref SchedulingGapPreferenceList

[0104] }

[0105] SchedulingGapPreferenceList::=SEQUENCE(SIZE(1..3))OFSchedulingGapPrefInfo

[0106] SchedulingGapPrefInfo::=SEQUENCE{

[0107] SchedulingStarting-SFN-AndSubframe SchedulingStarting-SFN-AndSubframeOPTIONAL (optional),

[0108] SchedulingGapLength ENUMERATED{ms3,ms4,ms6,ms10,ms20},

[0109] SchedulingGapRepetitionAndOffset CHOICE{

[0110] ms20 INTEGER(0..19),

[0111] ms40 INTEGER(0..39),...}OPTIONAL(optional)}

[0112] As a combination solution, the UE may also indicate the SG granularity information and the scheduling interval auxiliary information; and / or the network may accept the SG granularity indicated by the UE or the network may determine the SG based on the scheduling interval auxiliary information.

[0113] Embodiments of interaction between MN and SN

[0114] Various embodiments describe the interaction between MNs and SNs in a network for each scheduling interval granularity and network configuration.

[0115] When the interval granularity is indicated by the UE or determined by the network, the MN indicates the interval information and / or the interval granularity to the SN, and the SN may accept or reject the interval reservation. The network may configure the scheduling interval information and / or the interval granularity to the UE.

[0116] Figure 7 The interaction between the MN and the SN is shown: step 701, the UE (780) sends a UAI with an interval request to the MN (792) in the network A (790); step 702, the MN sends CG configuration information to the SN 794 in the network A; step 703, the SN sends the CG configuration to the MN; step 704, the MN sends a reconfiguration message to the UE; and / or step 705, the UE sends a reconfiguration complete message to the MN. Alternatively, when the UE or MN determines that the interval granularity is per CG group (e.g., SCG), in step 704a, the SN sends a reconfiguration message to the UE; and / or step 705a, the UE sends a reconfiguration complete message to the SN.

[0117] In some implementations, when the scheduling interval granularity is determined as per UE interval, the MN determines the interval information, and / or indicates the interval information and / or interval granularity (per UE) to the SN. The network configures the scheduling interval information and / or interval granularity to the UE.

[0118] In some embodiments, when the scheduling interval granularity is determined as per FR interval, and when the SCG includes a serving cell on the corresponding FR, the MN indicates the interval information and / or the interval granularity to the SN. The network configures the scheduling interval information and / or the interval granularity to the UE.

[0119] In some embodiments, when the scheduling interval granularity is determined as a per-CG interval, and when the per-CG interval is an MCG interval, no coordination is required; when the per-CG interval is an SCG interval, the MN indicates the interval information and / or the interval granularity to the SN. Then, the SN determines the scheduling interval information, and / or may send the SCG scheduling interval to the MN, and have the MN send the SCG scheduling interval to the UE. Alternatively and optionally, the SN may send the scheduling interval information directly to the UE via SRB3.

[0120] In some embodiments, when the scheduling interval granularity is determined as a per-CC interval, and when the SCG includes a serving cell on the corresponding CC, the MN indicates the interval information and / or the interval granularity and / or the relevant CC index to the SN. Then, the SN determines the scheduling interval information, and / or may send the SCG scheduling interval to the MN and have the MN send the SCG scheduling interval to the UE. Alternatively and optionally, the SN may send the scheduling interval information directly to the UE via SRB3.

[0121] In some embodiments, in the scheduling interval, the network may suspend uplink (UL) transmission and downlink (DL) transmission when the measurement interval is completed. Alternatively and optionally, as an enhancement, only DL may be affected, and / or the UE may send UL signaling (e.g., for the case of a scheduling interval with reduced capability).

[0122] In some embodiments, for coordination between the MN and the SN for a per-UE interval or a per-FR interval, the MN may send a schedulingGapConfigure to the SN in an inter-node message as follows:

[0123] schedulingGapConfigure:=SEQUENCE

[0124] {

[0125]

[0126] In some implementations, the MN sends the configuration to the UE in a reconfiguration message.

[0127] In some embodiments, when the interval granularity is determined to be an SCG interval, the MN may send scheduling interval assistance information to the SN, the SN determines the scheduling interval information, and / or may send the SCG scheduling interval to the MN and have the MN send the SCG scheduling interval to the UE. Alternatively and optionally, the SN directly sends the scheduling interval information to the UE via SRB3.

[0128] In some implementations, for coordination between the MN and the SN for the SCG interval, the MN may send a schedulingGapConfigure to the SN in an inter-node message as follows:

[0129]

[0130] In some implementations, when the SN sends schedulingGapConfigure to the MN, the MN may send schedulingGapConfigure to the UE in a reconfiguration message.

[0131] In some embodiments, for coordination between the MN and the SN for per CC interval, and when the interval granularity is determined as per CC interval, and when the SCG includes serving cells on the corresponding CC, the MN indicates the interval information and / or interval granularity and / or related CC index to the SN.

[0132] For example, the MN may send a schedulingGapConfigure to the SN in an inter-node message as follows:

[0133]

[0134] In some implementations, the SN may immediately determine the schedulingGapConfigure to the MN or to the UE via SRB3 as follows:

[0135]

[0136] In some implementations, when the SN sends schedulingGapConfigure to the MN, the MN may send schedulingGapConfigure to the UE in a reconfiguration message.

[0137] In various examples / implementations / embodiments of the present disclosure, the interval granularity may be configured for all intervals, or alternatively, the interval granularity may be configured for each interval.

[0138] Embodiments of UE indicating related capabilities

[0139] Various embodiments describe how the UE indicates relevant capabilities to the network. In some embodiments, the UE indicates the supported scheduling interval types (e.g., per UE interval, per FR interval, per CG interval, per CC interval) to the network in the UE capabilities. This capability can be used in MR-DC cases or CA (Carrier Aggregation) cases.

[0140] In some embodiments, the network configures the UE to report a preferred scheduling interval granularity (e.g., per UE interval, per FR interval, per CG interval, per CC interval).

[0141] In some embodiments, the network may also indicate a dedicated granularity to the UE in other configurations. For a non-limiting example, the network may indicate per UE / per FR / per CG, which means that the network only supports UE reporting these 3 types of granularity, i.e., per CC interval is not supported. For another non-limiting example, the network may indicate the supported scheduling interval types with a bitmap.

[0142] In some implementations, when the network only instructs the UE to report the interval granularity (without indicating a dedicated granularity), it means that the network supports all interval granularities and lets the UE determine the granularity.

[0143] The various examples / implementations / embodiments described in the present disclosure are applicable not only to MR-DC situations, but also to CA situations. Similarly, the various examples / implementations / embodiments described in the present disclosure are not limited to MUSIM UEs, and may be applicable to UEs that are simultaneously camped / connected to more than one network.

[0144] The various examples / implementations / embodiments described in the present disclosure may also be extended to any other intervals (eg, measurement intervals).

[0145] The present disclosure describes various embodiments for indicating temporary capability limitations for dual-RX / dual-TX UEs. In some embodiments, there are enhancements to the MUSIM process to operate in the RRC_CONNECTED state in both network (NW) A and NW B (e.g., RAN (Radio Access Network) 2, RAN3, and / or RAN4) simultaneously. When the UE needs to transmit or receive for MUSIM purposes (e.g., start / stop connection with NWB), a specified mechanism can be used to indicate temporary UE capability limitations and preferences for lifting the limitations with NW A (e.g., capability update, release of cells, (de)activation of configured resources). For radio access technology (RAT) concurrency, network A is NR SA (Standalone, independent networking) or NR DC (Dual Connectivity) (with CA); and / or network B can be LTE or NR. For applicable UE architectures, it can be a Dual-RX / Dual-TX UE.

[0146] For non-limiting example, Figure 8 An overall process for UE capability limitation indication and release is shown. The UE may include a SIM1 access stratum (AS) 882 and a SIM2 AS 884, which are configured to connect to SIM1 e / gNB A (network A) 892 and SIM2 e / gNB B (network B) 894, respectively. The process may include some or all of the following steps. In step 800, the UE may be in a connected state with network A and in an idle / inactive state with network B. In step 801, the UE needs to establish a connection with network B. In step 802, the UE (e.g., SIM1 AS) sends a UE capability limitation indication to network A. In step 803, network A sends a reconfiguration to the UE. In step 804, the UE sends a reconfiguration complete to network A. In step 805, the temporary capability limitation is released, for example, when the UE releases the connection with network B. In step 806, the UE sends a UE capability limitation release indication to network A. Optionally, in step 807, network A sends a reconfiguration to the UE. Optionally, in step 808, the UE sends a reconfiguration completion to network B.

[0147] In some embodiments, when the UE is in a connected state with a network and the UE needs to establish a connection with network B, the UE may indicate UE capability limitation to network A and wait for a response from network A (e.g., reconfiguration), and then after the UE releases the connection from network B, the UE may indicate to network B that the UE capability limitation is lifted.

[0148] In some embodiments, the UE may report temporary capability restrictions in the UAI, including but not limited to: allowed / prohibited band combinations (BCs) or feature sets or maximum MIMO layers, maximum number of CCs (such as energy saving / overheating), or secondary cell (Scell) / SCG release. Temporary capability restrictions may include capability updates, cell releases, and (de)activation of configured resources, etc. The UE may indicate such restrictions with band combination information.

[0149] In some implementations, in the current UE capability structure, a list of band combinations may be reported. For each BC, there may be a FeaturesetCombination. For each FeaturesetCombination, there may be one or more Featureset combinations.

[0150] For a non-limiting example, for BC1, there are 3 feature set combination entries; and BC1->FeaturesetCombination ID x

[0151]

[0152] In some implementations, to report temporary capability limitations, the UE may indicate at least one of the following BC lists.

[0153] Allowed BC List: BCs with corresponding feature set capabilities can be used without any restrictions.

[0154] List of affected BCs: There may be some restrictions on these BCs.

[0155] List of banned BCs: These BCs can be banned.

[0156] For the affected BC list, the UE may also indicate the affected feature set combination entries.

[0157] In some implementations, the feature set combination entry may include at least one of the following list of feature set combination entries.

[0158] List of allowed feature set combination entries: Feature set combination entries with corresponding feature set capabilities can be used without any restrictions.

[0159] List of affected feature set combination entries: There may be some restrictions on these feature set combination entries.

[0160] List of prohibited signature set combination entries: These signature set combination entries can be prohibited.

[0161] In some embodiments, for BC1, the UE may only support feature set combination entry 1 and feature set combination entry 3, and then the UE may indicate the prohibited feature set combination entry 2 to the prohibited feature set entry list for BC 1, or indicate feature set combination entry 1 and feature set combination entry 3 to the network. The UE may also indicate some other key restrictions (e.g., maximum MIMO layer, maximum modulation order) on these affected BC lists or on each BC included in the affected BC lists.

[0162] For a non-limiting example, in the above feature set combination entry 1 and feature set combination entry 3 which are allowed to be used but are affected by temporary UE capability limitations, the UE may also indicate maximum MIMO layers = 4 and maximum number of CCs = 2.

[0163] In some embodiments, the temporary capability restriction may include information of allowed / affected / prohibited BCs, a list of allowed / affected / prohibited feature set combination entries, and dedicated capability parameter restrictions (e.g., maximum MIMO layers, maximum modulation order). Dedicated capability parameter restrictions may be set for all BCs, or for each BC, or for each feature set combination entry of each BC.

[0164] In some implementations, similar to the above, the UE may also implicitly instruct the Scell / SCG to deactivate / release.

[0165] In some implementations, the network may determine Scell / SCG deactivation / release based on the above temporary capability limitation information.
