METHODS, APPARATUSES, AND COMPUTER READABLE MEDIA FOR CONFIGURING BANDWIDTH PARTS

TECHNICAL FIELD

Various embodiments relate to methods, apparatuses, and computer readable media for configuring bandwidth parts.

BACKGROUND

In a telecommunication system such as a long-term evolution (LTE or 4G) system and a new radio (NR or 5G) system, a user equipment (UE) or mobile station in a connected mode such as a radio resource control (RRC) connected (RRC_CONNECTED) state may transmit a multicast or broadcast services (MBS) interest indication such as a multimedia broadcast multicast services (MBMS) interest indication as specified in 3rd generation partnership project (3GPP) technique specifications (TS) to inform network about an interest of the UE in at least one MBS service, so that the network may configure suitable bandwidth parts to the UE for receiving the at least one MBS service.

DETAILED DESCRIPTION

Besides an MBS service reception in a connected state, another delivery mode (also referred to as broadcast delivery for all RRC states or delivery mode 2 herein) may also be supported for a UE, where the UE in a state such as an idle state (for example, a RRC idle state or RRC_IDLE state) and an inactive state (for example, a RRC inactive state or RRC_INACTIVE state) may also receive at least one MBS service. For example, for a broadcast reception, the same group-common physical downlink control channel (PDCCH) and the corresponding scheduled group-common physical downlink shared channel (PDSCH) may be received by both UEs in idle/inactive state and UEs in connected state when a UE-specific active bandwidth part (BWP) of a UE in the connected state includes common frequency resources (CFR) . A common frequency resource is a portion of cell bandwidth where the group-common PDCCH and the group-common PDSCH are transmitted.

In one or more example embodiments, an early BWP configuration may be enabled by transmitting an early indication from UE to network before a completion of an establishment or resumption of a RRC connection between the UE and the network. The network may be informed by the early indication that the UE is receiving at least one MBS service provided through at least one configured CFR or is interested in receiving at least one MBS service provided through at least one configured CFR. Then, the network may configure the UE with at least one suitable BWP based on such early indication before the completion of the establishment or resumption of the RRC connection.

FIG. 1 illustrates an example procedure of an early configuration of at least one BWP for a UE based on an early indication in an example embodiment.

As illustrated in FIG. 1, the UE 101 may transmit indication information 103 to the NW 102 before a completion of an establishment or resumption of a RRC connection between a UE 101 and a network (NW) 102, for example during or before establishing or resuming the RRC connection between the UE 101 and the network 102 when the UE 101 is still in an idle or inactive state.

For example, the indication information 103 may be associated with an ongoing reception of at least one MBS service provided through at least one configured CFR or an interest of receiving at least one MBS service provided through at least one configured CFR. In some examples, the indication information 103 may also include information for example associated with the at least one CFR, the at least one interested MBS service, and/or the like

In various example embodiments, the indication information 103 may be coded and transmitted in any suitable manner before the completion of an establishment or resumption of a RRC connection between the UE 101 and the NW 102.

In an example embodiment, the indication information 103 may be included or coded in at least one uplink RRC message for requesting to establish or resume the RRC connection between the UE 101 and the NW 102, such as a RRC setup request (RRCSetupRequest) or a RRC resume request (RRCResumeRequest) as specified in 3GPP TS 38.331.

For example, one or more bits in the RRC setup request and/or RRC resume request may be used as at least a part of the indication information 103, for example to indicate whether the UE 101 is performing at least one CFR reception or whether the UE 101 is interested in performing at least one CFR reception. For example, a last bit in the RRC setup request as specified in 3GPP TS 38.331 may be used as at least a part of the indication information 103.

For example, a cause parameter in the RRC setup request and/or RRC resume request, which is for indicating a cause of the establishment or resume request, may be used as at least a part of the indication information 103. For example, as at least a part of the indication information 103, one or more new parameter values may be determined for the cause parameter in the RRC setup request (for example, establishmentCause parameter in RRCSetupRequest as specified in 3GPP TS 38.331) or for the cause parameter in the RRC resume request (for example, resumeCause parameter in the RRCResumeRequest as specified in 3GPP TS 38.331) , to indicate whether the UE 101 is performing at least one CFR reception or whether the UE 101 is interested in performing at least one CFR reception. In some examples, the indication information 103 may not be available for one or more causes such as “emergency access” .

For example, the RRC setup request and/or the RRC resume request may also be extended in size by including one or more additional information elements (IEs) as at least a part of the indication information 103, to indicate whether the UE 101 is performing at least one CFR reception or whether the UE 101 is interested in performing at least one CFR reception.

In some examples, the indication information 103 included or coded in at least one uplink RRC message may also include information associated with at least one CFR through which at least one MBS service is being provided or is to be provided to the UE 101, such as frequencies and temporary mobile group identities (TMGIs) .

In another example embodiment, the UE 101, which for example is in the idle or inactive state and is receiving or is interested in receiving at least one MBS service provided through at least one CFR, may initiate a two-step random access (RA) procedure to establish or resume a RRC connection between the UE 101 and the NW 102, and may transmit the indication information 103 within an uplink medium access control (MAC) control element (CE) for example via an uplink message of the initiated two-step RA procedure (for example, message A of the two-step RA procedure which is also called as MsgA herein) , or the like.

For example, in a case where both two-step RA procedure and four-step RA procedure are available, in the MAC, a channel quality threshold used to determine which of the two-step RA procedure or the four-step procedure is used (for example, msgA-RSRP-Threshold as specified in 3GPP TS 38.331) may be ignored, and a variable indicating a type of the RA procedure to be initiated (for example the variable RA_TYPE as specified in 3GPP TS 38.331) may be configured always as a value corresponding to the two-step RA procedure (for example, “2-stepRA” as specified in 3GPP TS 38.331) , to ensure that the two-step RA procedure will be initiated.

Then, for example, an MBS interest indication (for example, a RRC message in the 5G system similar to the MBMS interest indication as specified for the 4G system in the 3GPP TS 36.331, which is transmitted to network by UE in the connected state) may be included in MsgA of the initiated two-step RA procedure, as at least a part of the indication information 103. For example, the MBS interest indication as at least a part of the indication information 103 may include information associated with one or more (for example, all) MBS services that the UE 101 is interested to receive, where such one or more MBS services may not yet be provided (for example, it is not known which one or more CFRs will be used by the network 102 for such one or more MBS services) . Thus, for example, service continuity later in a connected state may be provided, for example by prioritizing cells on frequencies indicated by the MBS interest indication (as at least a part of the indication information 103) as candidate cells for a handover.

In another example, another channel quality threshold for determining whether to use the two-step RA procedure, which is different from msgA-RSRP-Threshold as specified in the 3GPP TS 38.331 and is denoted as msgA-RSRP-Threshold2 herein, may be configured in the MAC for the UE 101 which is receiving or is interested in performing at least one CFR reception. Then, for example, the UE 101 may initiate the two-step RA procedure based on a measured channel quality and the msgA-RSRP-Threshold2, where the msgA-RSRP-Threshold2 may be used to indicate that the UE 101 is receiving or is interested in performing at least one CFR reception, and may be at least a part of the indication information 103.

In another example, at least one MAC CE, which for example may be included in an uplink message of a two-step RA procedure (for example, MsgA of the two-step RA procedure) or the like, may be configured to indicate that the UE 101 is receiving or is interested in performing at least one CFR reception, and may be at least a part of the indication information 103. For example, a MAC CE with a codepoint/index being for example 44 may be configured as at least a part of the indication information 103 for the early CFR reception indication. In another example, one or more reserved bits in some legacy MAC CEs may be reused as at least a part of the indication information 103, to indicate that the UE 101 is receiving or is interested in performing at least one CFR reception. For example, the MAC CE as at least a part of the indication 103 may be configured with a high multiplexing prioritization.

In another example embodiment, the indication information 103 may also include at least one preamble which is predetermined or allocated for at least one configured CFR and/or at least one MBS service.

For example, different preambles may be predetermined or allocated for different services or different CFRs or the like. For example, different preambles may be predetermined or allocated for different combinations of MBS services or CFRs, or may correspond to different group radio network temporary identities (G-RNTIs) . For example, such one or more preambles for indicating CFR receptions may be provided to the UE 101 via a system information broadcast, for example via a parameter RACH-ConfigCommon in BWP-UplinkCommon of UplinkConfigCommon carried in ServingCellConfigCommonSIB of SIB1 (system information block 1) as specified in the 3GPP TS 38.331.

Then, for example, the UE 101, which for example is in the idle or inactive state and is receiving or is interested in receiving one or more MBS services provided through one or more CFRs, may use a preamble corresponding to the one or more MBS services or the one or more CFRs when trying to establish or resume a RRC connection with the NW 102. For example, the UE 101 may use at least one preamble associated with one or more MBS services and/or CFRs when initiating a RA procedure, for example a two-step RA procedure described in the above examples or a four-step RA procedure. For example, the UE 101 may initiate a two-step RA procedure by ignoring the msgA-RSRP-Threshold and configuring the RA_TYPE as “2-stepRA” , and may include a preamble associated with at least one MBS services and an MBS interest indication in the MsgA.

Based on the used preamble, the NW 102 may determine whether the UE 101 is receiving or is interested in receiving one or more MBS services. Further, for example, based on a correspondence between the preamble and the CFRs or MBS services, the NW 102 may also determine information associated with the one or more MBS services or CFRs involved in the CFR receptions of the UE 101.

It is appreciated that implementations of the indication information 103 are not limited to the above examples, and any other suitable manners may be used by the UE 101 to code and transmit an early indication such as the indication information 103 to the NW 102, to notify the NW 102, before the completion of an establishment or resumption of a RRC connection between the UE 101 and the NW 102, that the UE 101 is receiving or is interested in receiving at least one MBS service provided through at least one CFR. Further, depending on the implementations of the indication information 103, besides explicit or implicit information for indicating that the UE 101 is receiving or is interested in receiving at least one MBS service provided through at least one CFR, the indication 103 may also include information associated with one or more MBS services or one or more CFRs, in any suitable manners or formats.

Then, as illustrated in FIG. 1, when the NW 102 receives the indication information 103 before the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, the NW 102 may configure the UE 101 with at least one BWP in an operation 104. For example, the at least one configured BWP may include (for example, fully) at least one configured CFR through which the UE 101 is receiving or is to receive at least one expected MBS service.

FIG. 2 illustrates an example of BWP configuration, where a CFR 201 is supported, a BWP 202 fully includes the CFR 201, a BWP 203 includes a part of the CFR 201, and BWPs 204 and 205 do not include the CFR 201. Then, in the operation 104, based on the received indication information 103, the NW 102 may configure the UE 101 with the BWP 202 which fully includes the CFR 201.

FIG. 3 illustrates another example of BWP configuration, where a CFR 301 and a CFR 302 are supported, a BWP 303 fully includes both the CFR 301 and the CFR 302, a BWP 304 also fully includes both the CFR 301 and the CFR 302, a BWP 305 does not include any of the CFR 301 and CFR 302, a BWP 306 fully includes the CFR 302 but does not include the CFR 301, and a BWP 307 fully includes the CFR 301 and partly includes the CFR 302.

Then, in the operation 104, if the received indication information 103 indicates that the UE 101 is receiving or is interested in receiving MBS services provided through both

CFRs

301 and 302, the NW 102 may configure the UE 101 with the BWP 303 and/or the BWP 304. For example, if the received indication information 103 indicates that the UE 101 is receiving or is interested in receiving MBS services provided through the CFR 301, the NW 102 may configure the UE 101 with the BWP 303 and/or the BWP 304 which fully include both the CFR 301 and the CFR 302, or may configure the UE 101 with one or more of the BWP 303, the BWP 304, and the BWP 307, which fully include the CFR 301.

When or after configuring BWP for the UE 101 in the operation 104, for example, the NW 102 may also configure one or more related layer 1 (L1) parameters, such as control resource sets, search spaces and monitoring occasions for the UE 101, so that the one or more related L1 parameters may match the parameters required for a continuous reception of the at least one MBS service by the UE 101.

Then, as illustrated in FIG. 1, the NW 102 may further transmit, to the UE 101, configuration information 105 which is determined in the operation 104 and may be associated with at least one BWP including at least one configured CFR for the at least one MBS service.

The UE 101 may configure the at least one BWP based on the received configuration information 105 in an operation 106. For example, in the operation 106, the UE 101 in the idle or inactive state may determine the at least one BWP indicated in the configuration information 105 as at least one active BWP, which may include at least one CFR through which the UE 101 may receive at least one expected MBS service.

As illustrated in FIG. 1, by providing an early indication (for example, the indication information 103) to the NW 102 before a completion of an establishment or resumption of a RRC connection between the UE 101 and the NW 102, the NW 102 may be aware of whether the UE 101 in an idle or inactive state is receiving or is interested in receiving at least one MBS service on at least one configured CFR, and may configure at least one suitable BWP for the UE 101 early before the completion of an establishment or resumption of a RRC connection between the UE 101 and the NW 102. Thus, for example, the reception of the at least one MBS service of the UE 101 in the idle or inactive state will not be interrupted. Also, for example, the NW 102 may configure at least one suitable BWP quickly when the UE 101 is not receiving an MBS service on a CFR.

FIG. 4 illustrates another example procedure of an early configuration of at least one BWP for a UE based on an early indication in an example embodiment.

As illustrated in FIG. 4, after the RRC connection between the UE 101 and the NW 102 is established or resumed, the UE 101 may also transmit an MBS interest indication 401 (for example, a RRC message in the 5G system similar to the MBMS interest indication as specified for the 4G system in the 3GPP TS 36.331) to the NW 102, for example to provide the NW 102 with complete information about at least one MBS service which the UE 101 is receiving or is interested to receive.

In some examples, the transmission of the MBS interest indication 401 may be optional. For example, the transmission of the MBS interest indication 401 may be omitted if the indication information 103 is implemented by including an MBS interest indication in MsgA of an initiated two-step RA procedure and the MBS interest indication in the MsgA has already included information about the at least one MBS service which the UE 101 is interested to receive.

Further, in some examples which are also illustrated in FIG. 4, after the RRC connection between the UE 101 and the NW 102 is established or resumed, the NW 102 may perform an operation 402 to configure one or more other BWPs for the UE 101 and may transmit configuration information 403 associated with the one or more other BWPs to the UE 101.

For example, the one or more other BWPs may correspond to the one or more BWPs configured in the operation 104. For example, the one or more other BWPs configured in the operation 402 may be at least partly different from the one or more BWPs configured in the operation 104, but may include (for example, fully include) the at least one CFR for the at least one MBS service previously indicated by the indication information 103. For example, the one or more other BWPs configured in the operation 402 may also include (for example, fully include) one or more other CFRs for one or more other MBS services for the UE 101.

Then, in an operation 404, the UE 101 may configure the one or more other BWPs based on the received configuration information 403, for example in addition to the at least one BWP configured in the operation 106 or to replace the at least one BWP configured in the operation 106.

FIG. 5 illustrates another example procedure of an early configuration of at least one BWP for a UE based on an early indication in an example embodiment.

As illustrated in FIG. 5, the NW 102 may further configure whether the indication information 103 is enabled for the UE 101, and may transmit, to the UE 101, information 501 for indicating whether the indication information 103 is enabled for the UE 101. The information 501 may be transmitted by the NW 102 to the UE 101 in any suitable manner and at any suitable occasion which is not limited to a period when the UE 101 is in an idle or inactive state.

For example, the information 501 may include at least one indication (for example, at least one bit flag or at least one enumeration value) for indicating which one manner or which manners are enabled for the UE 101 to code and/or transmit the indication information 103.

For example, if a manner of coding at least a part of the indication information 103 in one or more bits in a RRC message for establishing or resuming the RRC connection is enabled by the information 501, for example if the UE 101 receives the information 501, the UE 101 may use one or more bits in the RRC message for establishing or resuming the RRC connection as at least a part of the indication information 103. If the manner of coding at least a part of the indication information 103 in one or more bits in the RRC message for establishing or resuming the RRC connection is disabled by the information 501, for example if the UE 101 does not receive the information 501, the one or more bits in the RRC message for establishing or resuming the RRC connection may be used for other purposes, for example rather than being used as at least a part of the indication information 103.

For example, if a manner of coding at least a part of the indication information 103 in one or more bits in a RRC message for establishing or resuming the RRC connection is disabled by the information 501, the UE 101 may use another manner to code and transmit the indication information 103, for example by using a preamble corresponding to a set of CFRs or a set of MBS services in a RA procedure (for example, a two-step RA procedure) for establishing or resuming the RRC connection with the NW 102.

For example, if the indication information 103 is enabled by the information 501, the UE 101 may code and transmit the indication information 103 in an idle or inactive state, in at least one manner including, but not limited to: using one or more bits in a RRC control message for requesting to establish or resume a RRC connection; using at least one parameter for indicating a cause of the establishment or resumption in the RRC control message for requesting to establish or resume a RRC connection; using at least one additional IE in an extended RRC control message for requesting to establish or resume a RRC connection; using an MBS interest indication in MsgA of a two-step RA procedure; using a MAC CE in MsgA of a two-step RA procedure; using at least one predetermined preamble; and so on.

For example, if the indication information 103 is disabled by the information 501, the UE 101 may disable the transmission of the indication information 103. Then, for example, the NW 102 may configure the UE 101 with any BWP, for example without requiring the configured BWP to include fully the at least one CFR through which the UE 101 is receiving or is interested in receiving at least one MBS service.

Further, in some example embodiments, MBS services may be associated with two or more service priorities. For example, a first service priority may be associated with one or more MBS services, such as those MBS services which are not yet started, those MBS services which are started but not critical for a UE if a short interruption happens after establishing or resuming the RRC connection, and so on. For example, the first service priority may be lower than a priority of a unicast. A second service priority may be associated with one or more other MBS services, such as those MBS services which have started and for which a UE does not want an interruption. For example, the second service priority may be higher than a priority of a unicast.

For example, if the NW 102 determines, for example based on the indication information 103 from the UE 101, that the UE 101 is receiving or is interested in receiving at least one first MBS service with the first service priority, then the operation 104 of the NW 102, together with consequent transmission of the configuration information 105 from the NW 102 to the UE 101 as well as the operation 106 performed by the UE 101, may be stopped or omitted, and the NW 102 may configure at least one suitable first BWP for the UE 101 before or after the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102 (for example, when the UE 101 is in the connected state) .

For example, if the NW 102 determines that the UE 101 is receiving at least one second MBS service with the second service priority, for example in addition to or in lieu of receiving or being interested in receiving the at least one first MBS service with the first service priority, then in the operation 104, the NW 102 may configure at least one second BWP including (for example, fully including) at least one CFR through which the UE 101 is receiving the at least one MBS service before the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, even if the at least one configured BWP may be not optimal for the UE 101.

In an example embodiment, the information associated with the service priorities of one or more MBS services may be provided by an MBS interest indication from the UE 101 to the NW 102, which for example may be the MBS interest indication in the MsgA and as at least a part of the indication information 103, and/or the MBS interest indication 401 transmitted from the UE 101 to the NW 102 after the RRC connection is established or resumed.

In another example embodiment, the NW 102 may configure a first preamble for one or more MBS services with the first service priority, and configure a second preamble for one or more MBS services with the second service priority.

For example, if the UE 101 is receiving or is interested in receiving at least one MBS service for example with the first service priority, the UE 101 may disable a transmission of the indication information 103, or the UE 101 may initiate a RA procedure with a preamble not corresponding to the MBS services with the second service priority, for example with the first preamble corresponding to the MBS services with the first service priority or another preamble different from both the first preamble and the second preamble.

Then, the NW 102 may disable the operation 104, for example if the NW 102 does not receive the indication information 103 for example before the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, or if the NW 102 determines, based on the indication information 103 received before the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, that the at least one MBS service being received by the UE 101 is not associated with the second service priority for which the UE 101 does not want an interruption, or that the at least one MBS service being received or being interested by the UE 101 is associated with the first service priority, which is not that critical. For example, the NW 102 may configure at least one suitable BWP for the UE 101 before or after the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102 (for example, when the UE 101 switches into the connected state from the idle or inactive state) , which may result in a service interruption for the at least one MBS service of the UE 101.

For example, if the UE 101 is receiving at least one MBS service for example with the second service priority, the UE 101 may initiate a RA procedure with the second preamble corresponding to the MBS services with the second service priority.

Thus, the NW 102 may be informed by the second preamble that the UE 101 is receiving at least one MBS service for which no interruption is expected, and may configure, for example in the operation 104, at least one BWP including (for example, fully including) at least one CFR through which the CFR reception of the UE 101 is being performed.

In yet another example embodiment, as illustrated in FIG. 6, the NW 102 may obtain or receive information 602 associated with types and/or priorities of different MBS services or different groups of MBS services from a core network (CN) 601, for example originated from a policy control function (PCF) of the CN 601. For example, the information 602 may be provided as a part of the MBS quality of service (QoS) profile from the CN 601 to the NW 102. For example, the NW 102 may receive the information 602 at a beginning of an MBS session.

For example, a plurality of MBS services may be categorized into one or more service types, and a plurality of service priorities may be configured for the plurality of MBS services. Then, for example if there are two MBS services with the same type but different service priorities and these two MBS services is being provided or is to be provided on two different CFRs which cannot be received by the UE 101 concurrently, then the NW 102 may configure the UE 101 with at least one suitable BWP, based on the information 602, for example in the operation 104 and/or the operation 402, to ensure the UE 101 is able to receive at least the MBS service with a higher service priority of the two MBS services.

In another example, the MBS services may be categorized according to a plurality of service types corresponding to respective service priorities. For example, the MBS services may be categorized into a first MBS service type corresponding to a first service priority and a second MBS service type corresponding to a second service priority, where the first MBS service type may include those MBS services which are not yet started, those MBS services which are started but not critical for a UE if a short interruption happens after establishing or resuming the RRC connection, and so on, and the second MBS service type may include those MBS services which have started and for which a UE does not want an interruption.

Then, for example, in the

operation

104 or 402, the NW 102 may determine a service priority of at least one MBS service which the UE 101 is receiving or is interested in receiving, based on the information 602. For example, if the at least one MBS service is associated with the first service type, the NW 102 may configure at least one suitable first BWP for the UE 101 before or after the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102 (for example, when the UE 101 is in the connected state) , for example in the operation 402. For example, if the at least one MBS service is associated with the second service type, the NW 102 may configure at least one second BWP including (for example, fully including) at least one CFR through which the UE 101 is receiving the at least one second MBS service before the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, so that the UE 101 in the idle or inactive state may receive the at least one second MBS service, even if the at least one configured BWP is not optimal for the UE 101.

FIG. 7 illustrates another example procedure of an early configuration of at least one BWP for a UE in an example embodiment.

In a case where the indication information 103 is not provided by the UE 101 to the NW 102 before the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, for example if a transmission of the indication information 103 is disabled for example by the NW 102 (for example by the information 501 in the above example) , or if a reception of the indication information 103 is not supported by the NW 102, or if the UE 101 does not support to provide the indication information 103, then as illustrated in FIG. 7, the NW 102 may configure at least one predetermined BWP for the UE 101 in an operation 701, and transmit information 702 associated with the at least one predetermined BWP to the UE 101. For example, the at least one predetermined BWP may include one or more CFRs, for example all CFRs associated with a cell if UE’s capability allows, so that a MBS service provided through any of these CFRs of the cell may be received by the UE 101. Further, also as illustrated in FIG. 7, the operation 701 may be performed when the NW 102 receives information 703 associated with the establishment or resumption of the RRC connection between the UE 101 and the NW 102. For example, the information 703 may include any suitable uplink signaling or message from the UE 101 to the NW 102, which may include, but not limited to, an uplink message or signaling on a physical random access channel (PRACH) during a four-step RA procedure (also called as message 1 or Msg1 herein) , an uplink message or signaling on a physical uplink shared channel (PUSCH) during a four-step RA procedure (also called as message 3 or Msg3 herein) which may include a RRC message for request to establish or resume the RRC connection without an MBS interest indication, MsgA of a two-step RA procedure without an MBS interest indication, and/or the like.

Further, as illustrated in FIG. 7, if the NW 102 receives the MBS interest indication 401 from the UE 101 after the RRC connection between the UE 101 and the NW 102 is established or resumed, the NW 102 may reconfigure BWP for the UE 101 in the operation 402.

In another example embodiment, for example as illustrated in FIG. 8, if a predetermined time elapsed since the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, for example in case of an expiration of a predetermined time period for receiving the indication information 103 after the completion of the establishment or resumption of the RRC connection between the UE 101 and the NW 102, the NW 102 may be sure that the UE 101 is not receiving a MBS service.

Then, the NW 102 may configure at least one other BWP for the UE 101 in an operation 801, and may transmit configuration information 802 associated with the at least one other BWP configured in the operation 801 to the UE 101. For example, the at least one other BWP configured in the operation 801 may be any one or more suitable BWPs, which may not necessarily include one or more CFRs. For example, the at least one other BWP configured in the operation 801 may be or may include one or more BWPs which do not include the at least one predetermined BWP configured for the UE 101 in the operation 701.

As described above, through the early configuration in one or more example embodiments, the reception of the at least one MBS service of a UE in the idle or inactive state will not be interrupted. Also, for example, the network may configure at least one suitable BWP quickly when the UE is not receiving an MBS service on a CFR.

It is appreciated that this disclosure is not limited to the above examples.

FIG. 9 illustrates an example method 900 for configuring at least one BWP in an embodiment. For example, the example method 900 may be performed by a UE or mobile station, such as the UE 101 in the above examples.

As illustrated in FIG. 9, the example method 900 may include an operation 901 and an operation 902. In the operation 901, the UE may receive configuration information associated with at least one BWP, such as the

configuration information

105 or 702 in the above examples, before a completion of an establishment or resumption of a RRC connection. For example, the at least one BWP may include (for example, fully include) at least one CFR for at least one MBS service. Then, in the operation 902, the UE may configure at least one BWP based on the configuration information received in the operation 901.

Thus, for example, an early configuration of at least one BWP may be enabled for the UE before the completion of the establishment or resumption of the RRC connection, for example when the UE is still in an idle or inactive state.

In some example embodiments, in the example method 900, the UE may further transmit indication information for an ongoing reception of the at least one MBS service provided through the at least one configured CFR or an interest of receiving the at least one MBS service provided through the at least one configured CFR, such as the indication information 103 in the above examples, before the completion of the establishment or resumption of the RRC connection. Thus, an early indication of at least one CFR reception may be provided to network, so that the early configuration of the at least one BWP may be enabled.

In some example embodiments, the indication information may be included in at least one uplink RRC message for the establishment or resumption of the RRC connection, such as at least one of the RRC setup request message or the RRC resume request message as specified in the 3GPP TS 38.331. For example, the indication information may include one or more of: at least one bit in the at least one uplink RRC message; at least one parameter for indicating a cause of the establishment or resumption in the at least one uplink RRC message; at least one IE in the at least one uplink RRC message; or the like.

In some example embodiments, in the example method 900, the UE may initiate RA procedure, for example may initiate a two-step RA procedure to establish or resume the RRC connection, for example by ignoring a channel quality threshold for estimating whether to use the two-step RA procedure (such as the msgA-RSRP-Threshold as specified in the 3GPP TS 38.331) , or based on a measured channel quality and another channel quality threshold which is different from the channel quality threshold for estimating whether to use the two-step RA procedure (such as the msgA-RSRP-Threshold as specified in the 3GPP TS 38.331) . Then, for example, the indication information may include an MBS interest indication associated with the at least one MBS service provided through the at least one CFR, and the MBS interest indication may be included in an uplink message of the two-step RA procedure, for example in the MsgA of the two-step RA procedure. In another example, the indication information may be included in an uplink MAC CE.

In some example embodiments, the indication information may also include at least one predetermined preamble associated with at least one of the at least one CFR or the at least one MBS service. For example, in the example method 900, the UE may further receive information associated with the at least one predetermined uplink preamble via at least one system information broadcast such as SIB1.

In some example embodiments, in the example method 900, the UE may further receive information for indication whether the indication is enabled, such as the information 501 in the above examples.

In some example embodiments, the at least one MBS service may be associated with at least one service priority satisfying a predetermined priority condition. For example, the at least one MBS service may be at least one MBS service which has started and for which the UE does not want an interruption. For example, the at least one service priority of the at least one MBS service may be higher than a priority of a unicast service.

In some example embodiments, in the example method 900, the UE may further transmit an MBS interest indication associated with at least one MBS service provided through the at least one CFR, such as the MBS interest indication 401 in the above examples, after the completion of the establishment or resumption of the RRC connection. For example, the MBS interest indication may include information associated with a plurality of service priorities of a plurality of MBS services including the at least one MBS service.

In some example embodiments, in the example method 900, after the competition of the establishment or resumption of the RRC connection, the UE may further receive one or more other configuration information associated with one or more other BWPs, such as the configuration information 403 and/or 802 in the above examples. For example, the one or more other BWPs may include at least one CFR for the at least one MBS service, or the one or more other BWPs may include one or more other CFRs for one or more other MBS services. Further, in the operation method 900, the UE may configure the one or more other BWPs based on the one or more other configuration information.

FIG. 10 illustrates another example method 1000 for configuring at least one BWP in an embodiment. For example, the example method 1000 may be performed by a network node in a network such as the network 102 in the above examples, for example by a base station in the network.

As illustrated in FIG. 10, the example method 100 may include an operation 1001 and an operation 1002. In the operation 1001, the network may configure at least one BWP including at least one CFR for at least one MBS service, before a completion of an establishment or resumption of a RRC connection. Then, in the operation 1002, the network may transmit configuration information associated with the at least one BWP, such as the

configuration information

105 or 702 in the above examples.

Thus, for example, an early configuration of at least one BWP may be enabled for the UE by the network before the completion of the establishment or resumption of the RRC connection, for example when the UE is still in an idle or inactive state.

In some example embodiments, in the example method 1000, the network may further receive indication information for an ongoing reception of the at least one MBS service provided through the at least one configured CFR or an interest of receiving the at least one MBS service provided through the at least one configured CFR, such as the indication information 103 in the above examples, before the completion of the establishment or resumption of the RRC connection. For example, the operation 1001 may be performed based on the received indication information.

In some example embodiments, the indication information may be included in at least one uplink RRC message for the establishment or resumption of the RRC connection, such as at least one of the RRC setup request message or the RRC resume request message as specified in the 3GPP TS. For example, the indication information may include one or more of: at least one bit in the at least one uplink RRC message; at least one parameter for indicating a cause of the establishment or resumption in the at least one uplink RRC message; at least one IE in the at least one uplink RRC message; or the like.
