Description

[0001] USER EQUIPMENT, RADIO NETWORK NODE, AND METHODS PERFORMED THEREINTECHNICAL FIELD Embodiments herein relate to a user equipment (UE), a radio network node, and methodsperformed therein regarding wireless communication. Furthermore, a computer program productand a computer readable storage medium are also provided herein. In particular, embodimentsherein relate to handling communication, such as handling paging, in a wireless communicationnetwork. BACKGROUND In a typical wireless communication network, UEs, also known as wireless communicationdevices, mobile stations, stations (STA) and / or wireless devices, communicate via a Radio AccessNetwork (RAN) with one or more core networks (CN). The RAN covers a geographical area which is divided into service areas or cells, with each service area or cell being served by a radio network node such as an access node e.g. a Wi-Fi access point or a radio base station (RBS), which insome networks may also be called, for example, a NodeB, a gNodeB, or an eNodeB. The servicearea or cell is a geographical area where radio coverage is provided by the radio network node. The radio network node operates on radio frequencies to communicate over an air interface with the UEs within range of the radio network node. The radio network node communicates over adownlink (DL) to the UE and the UE communicates over an uplink (UL) to the radio network node.A Universal Mobile Telecommunications System (UMTS) is a third generation (3G)telecommunication network, which evolved from the second generation (2G) Global System for Mobile Communications (GSM). The UMTS terrestrial radio access network (UTRAN) is essentially a RAN using wideband code division multiple access (WCDMA) and / or High-Speed Packet Access (HSPA) for communication with user equipment. In a forum known as the Third Generation Partnership Project (3GPP), telecommunications suppliers propose and agree upon standards for present and future generation networks and investigate e.g. enhanced data rate and radio capacity. In some RANs, e.g. as in UMTS, several radio network nodes may be connected, e.g., by landlines or microwave, to a controller node, such as a radio network controller (RNC) or a base station controller (BSC), which supervises and coordinates various activities of the plural radio network nodes connected thereto. The RNCs are typically connected to one or more core networks. Specifications for the Evolved Packet System (EPS) have been completed within the 3GPPand newer 3GPP releases, such as New Radio (NR), have been developed and are worked on.The EPS comprises the Evolved Universal Terrestrial Radio Access Network (E-UTRAN), also known as the Long-Term Evolution (LTE) radio access network, and the Evolved Packet Core(EPC), also known as System Architecture Evolution (SAE) core network. E-UTRAN / LTE is a3GPP radio access technology wherein the radio network nodes are directly connected to the EPC core network. As such, the Radio Access Network (RAN) of an EPS has an architecture comprising radio network nodes connected directly to one or more core networks. With 5G technologies such as NR, the use of very many transmit- and receive-antennaelements may be of great interest as it makes it possible to utilize beamforming, such as transmit-side and receive-side beamforming. Transmit-side beamforming means that the transmitter can amplify the transmitted signals in a selected direction or directions, while suppressing the transmitted signals in other directions. Similarly, on the receive-side, a receiver can amplify signals from a selected direction or directions, while suppressing unwanted signals from other directions. NR is connected to the 5G Core Network (5GC) which comprises a number of Network Functions (NF) such as Session Management Function (SMF), Access Management Function (AMF),Authentication Service Function (AUSF), Policy Control Function (PCF), Unified Data Manager(UDM), Network Repository Function (NRF), Network Exposure Function (NEF), just to mention some. In the 5GC, NFs can discover other NFs by using a discovery service provided by the NRF. The 3GPP Release 19 Work Item entitled “Enhancements of network energy savings for NR” includes the following objective related to on-demand system information block (SIB) such as SIB1 transmission, see 3GPP Work Item Description: Enhancements of network energy savings for NR, 3GPP RP-234065, December 2023: 2. Study procedures and signaling method(s) to support on-demand SIB1 for UEs in idle / inactivemode, including: [RAN1 / 2 / 3] •Triggering method by uplink wake-up-signal using an existing signal / channel.• Wake-up-signal configuration provisioning to UE- Note: No modification of SSB will be discussed under this objective• Information exchange between gNBs at least for the configuration of wake-up signal, ifnecessary. •Checkpoint for normative work in RAN#105NW energy consumption: For a cell in NR, typically, a synchronization signal block (SSB) is transmitted periodically, and it may be used to aid a UE to perform an initial cell search, acquire frame / slot timing, performinitial time / frequency synchronization, perform measurements, and / or be regarded as a quasicollocated (QCL) reference for channels / signals, etc. With beamforming, SSBs must be transmitted in multiple beams. The master information block (MIB) is a part of the SSB, and together with system information block one (SIB1) they are called Minimum System Information (Minimum SI).UEs are configured with the above, such as SSB, SIB1, SI, and / or timing / rate information either ina RRC_IDLE / INACTIVE state via broadcast system information or in a RRC_Connected state viadedicated radio resource control (RRC) messages. In IDLE / INACTIVE state, the information suchas ssb-PositionsInBurst and ssb-PeriodicityServing for the serving cell is configured via a SIB1configuration. The MIB includes the system information (SI) transmitted from the network (NW) on the broadcast channel (BCH). Below is the MIB information element (IE) in ASN.1 format: MIB ::= SEQUENCE { systemFrameNumber BIT STRING (SIZE (6)), subCarrierSpacingCommon ENUMERATED {scs15or60, scs30or120}, ssb-SubcarrierOffset INTEGER (0..15), dmrs-TypeA-Position ENUMERATED {pos2, pos3}, pdcch-ConfigSIB1 PDCCH-ConfigSIB1, cellBarred ENUMERATED {barred, notBarred}, intraFreqReselection ENUMERATED {allowed, notAllowed}, spare BIT STRING (SIZE (1)) }The Information Element (IE) for the Physical Downlink Control Channel (PDCCH), i.e., PDCCH-ConfigSIB1, see IE below, within the MIB is used to configure CORESET#0 and search space#0. PDCCH-ConfigSIB1 ::= SEQUENCE { controlResourceSetZero ControlResourceSetZero, searchSpaceZero SearchSpaceZero } If a SIB1 is not transmitted in a cell, the existing specifications state that a UE shall treat acell not providing SIB1 as a barred cell. The UE shall:1> if in RRC_IDLE or in RRC_INACTIVE or in RRC_CONNECTED while timer T311 isrunning: 2> if the UE is unable to acquire the MIB:… 2> else if the UE is unable to acquire the SIB1:3> consider the cell as barred in accordance with TS 38.304

[0020] ;Timer T311 is a timer for cell selection procedure and the UE transitions to RRC_IDLE or in RRC_INACTIVE upon expiry. The purpose of an on-demand SIB1 transmission is to assist saving power on signaling andcontributing to the network energy saving (NES) gains of the work item. A cell implementing theon-demand SIB1 transmission is termed herein as a NES cell. A NES cell may not provide SIB1transmissions in idle mode and a UE cannot proceed to camp on the NES cell, initiate randomaccess procedure to transition to connected mode at the NES cell or start a cell (re-)selection procedure, unless the SIB1 is provided as requested. The feature can be significantly facilitated if the NES cell is related to some other coverage cell, which takes care of a part of the required signalling, i.e., acts as an anchor cell. That is, the NES cell provides periodic SSB transmission and, hence, a UE can receive this SSB and decode the associated MIB. The UE can request for the on-demand SIB1 from the NES cell where the configuration should be informed by either the NES cell or the anchor cell. The 3GPP RAN1_116 meeting has an agreement on WUS design for on-demand SIB1, see R1-2401663, FL summary 3 for on-demand SIB1 in idle / inactive mode, Moderator (MediaTek). Agreement -For study of UL WUS design, consider at least Physical Random Access Channel (PRACH)as a starting point -For further studying (FFS): Whether there is a dedicated PRACH resource for SIB1request -Other option(s) not precludedPRACH or Random Access Channel (RACH) resources are configured via higher layers,e.g., system information, and typical RACH resources may occur periodically as shown in Fig.1.After sending a RACH request, the UE monitors for a RACH response in a search space, e.g., ara-searchSpace that is configured by higher layers, and if the UE does not receive a responsewithin a pre-determined amount of time, the UE tries to send the RACH request again. Fig.1shows an illustration of uplink resources for random access, e.g., one RACH occasion (RO) insubframe #4 of each radio frame. The information element (IE) RACH-ConfigCommon is used to specify the cell specificrandom-access parameters.-- ASN1START-- TAG-RACH-CONFIGCOMMON-STARTRACH-ConfigCommon ::= SEQUENCE { rach-ConfigGeneric RACH-ConfigGeneric, totalNumberOfRA-Preambles INTEGER (1..63)OPTIONAL, -- Need Sssb-perRACH-OccasionAndCB-PreamblesPerSSB CHOICE { oneEighth ENUMERATED {n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64}, oneFourth ENUMERATED {n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64}, oneHalf ENUMERATED {n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64}, one ENUMERATED {n4,n8,n12,n16,n20,n24,n28,n32,n36,n40,n44,n48,n52,n56,n60,n64}, two ENUMERATED {n4,n8,n12,n16,n20,n24,n28,n32}, four INTEGER (1..16), eight INTEGER (1..8), sixteen INTEGER (1..4) }OPTIONAL, -- Need MgroupBconfigured SEQUENCE { ra-Msg3SizeGroupA ENUMERATED {b56, b144, b208, b256, b282, b480, b640, b800, b1000, b72, spare6, spare5,spare4, spare3, spare2, spare1}, messagePowerOffsetGroupB ENUMERATED { minusinfinity, dB0, dB5, dB8, dB10, dB12, dB15, dB18}, numberOfRA-PreamblesGroupA INTEGER (1..64) }OPTIONAL, -- Need Rra-ContentionResolutionTimer ENUMERATED { sf8, sf16, sf24, sf32, sf40, sf48, sf56, sf64}, rsrp-ThresholdSSB RSRP-RangeOPTIONAL, -- Need Rrsrp-ThresholdSSB-SUL RSRP-RangeOPTIONAL, -- Cond SULprach-RootSequenceIndex CHOICE { l839 INTEGER (0..837), l139 INTEGER (0..137) }, msg1-SubcarrierSpacing SubcarrierSpacingOPTIONAL, -- Cond L139restrictedSetConfig ENUMERATED {unrestrictedSet, restrictedSetTypeA, restrictedSetTypeB}, msg3-transformPrecoder ENUMERATED {enabled}OPTIONAL, -- Need R..., [[ ra-PrioritizationForAccessIdentity-r16 SEQUENCE { ra-Prioritization-r16 RA-Prioritization, ra-PrioritizationForAI-r16 BIT STRING (SIZE (2)) }OPTIONAL, -- Cond InitialBWP-Onlyprach-RootSequenceIndex-r16 CHOICE { l571 INTEGER (0..569), l1151 INTEGER (0..1149) }OPTIONAL -- Need R]], [[ ra-PrioritizationForSlicing-r17 RA-PrioritizationForSlicing-r17OPTIONAL, -- Cond InitialBWP-OnlyfeatureCombinationPreamblesList-r17 SEQUENCE (SIZE(1..maxFeatureCombPreamblesPerRACHResource-r17)) OFFeatureCombinationPreambles-r17 OPTIONAL -- Cond AdditionalRACH]] }-- TAG-RACH-CONFIGCOMMON-STOP-- ASN1STOP

SUMMARY As part of developing embodiments herein one or more issues have been identified. A UEmay send a preamble for WUS to a coverage cell or to a NES cell to request on-demand SIB1. The coverage cell or the NES cell may respond in terms of sending the SIB1. Network (NW) classifies RACH corresponding beam via SSB-RACH occasion (RO) mapping indicated by ssb-perRACH-OccasionAndCB-PreamblesPerSSB. As a part of Minimum System Information, the SIB1 isconventionally provided to all UEs along with the MIB in all transmitted SSB beams. Therefore, broadcast SIB1 is beam swept to cover UEs in the entire cell coverage area. Extending the conventional SIB1 transmission approach to distribute on-demand SIB1 that is requested by aspecific UE, results in a waste of NW resources and energy and may increase the responselatency of the on-demand SIB1. An object of embodiments herein is to support communication in a wireless communicationnetwork in an energy efficient manner.According to an aspect, the object is achieved, according to some embodiments herein, byproviding a method performed by a radio network node for handling communication in a wirelesscommunication network. The radio network node receives an indication indicating a request forsystem information from a UE. The radio network node selects a subset of SSB beams out of a setof SSB beams, based to the received indication, wherein the selected subset of SSB beamscorresponds to the received indication and transmits the requested system information in thesubset of SSB beams. According to another aspect the object is achieved, according to some embodiments herein, by providing a method performed by a UE for handling communication in awireless communication network. The UE transmits to a radio network node an indication indicatinga request for system information, and further indicating a subset of SSB beams out of a set of SSBbeams to provide the requested system information to the UE. The UE then receives from the radionetwork node the requested system information in the subset of SSB beams It is furthermore provided herein a computer program product comprising instructions, which, when executed on at least one processor, cause the at least one processor to carry out themethods herein, as performed by the UE or the radio network node, respectively. It is additionallyprovided herein a computer-readable storage medium, having stored thereon a computer program product comprising instructions which, when executed on at least one processor, cause the at leastone processor to carry out the methods herein, as performed by the UE or the radio network node,respectively. Furthermore, according to another aspect the object is achieved, according to someembodiments herein, by providing a UE and a radio network node configured to perform themethods herein, respectively.Thus, according to an aspect the object is achieved, according to some embodimentsherein, by providing a radio network node for handling communication in a wireless communicationnetwork. The radio network node is configured to receive from a UE, an indication indicating a request for system information. The radio network node is further configured to select a subset ofSSB beams out of a set of SSB beams, in response to the received indication wherein the selectedsubset of SSB beams corresponds to the received indication and is configured to transmit therequested system information in the subset of SSB beams. According to another aspect the object is achieved, according to some embodiments herein, by providing a UE for handling communication in a wireless communication network. The UE is configured to transmit to a radio network node an indication indicating a request for systeminformation, and further indicating a subset of SSB beams out of a set of SSB beams to provide therequested system information to the UE. The UE then receives the requested system informationfrom the radio network node (12) in the subset of SSB beams.It is proposed herein to provide a solution for a cell providing on-demand systeminformation, such as SIB1, requested by a UE in a subset of SSB beams, rather than in all beams,to save energy. The radio network node selects one or more SSB beams corresponding to, forexample, a received PRACH preamble and / or RO by using a configured SSB-RO mapping. Thus,a certain SSB is mapped to a certain RO used for the PRACH preamble, and / or the PRACHpreamble. The radio network node transmits the SI, for example, on-demand SIB1, only in the oneor multiple beams SSB beams out of the (full) set of SSB beams.The selected SSB beams may include, in addition to the SSB beams explicitly mapped to the received preamble, additional SSB beams with a spatial neighbor relationship to the explicitlymapped SSB beams, or to the UE location estimated via, e.g., angle of arrival (AoA) estimation inthe preamble receiver. In one aspect, the one or more beams in which SI will be provided may be specified withinthe response / acknowledgement, e.g. Random Access Response (RAR), to the on-demand SIB1request (WUS). Furthermore, the radio network node may in such response indicate timing information related to SIB1 provision, such as starting time and / or for how long the SIB1 will be provided. According to embodiments herein, the radio network node transmits SI such as on-demand SBI1 only in a subset of beams and thereby reduces energy consumption at the radio network node. It also reduces network resources usage, such as usage of physical resource blocks, for SIdistribution, and thereby increases resource availability for data transmission which improves theuser experience. Finally, it reduces the latency of system information provision since the deliverytime is shortened for UEs covered in “later” SSB beams. Thus, embodiments herein providecommunication in the wireless communication network in an energy efficient manner.

Action 302. The UE 10 transmits the indication indicating the request for systeminformation. The indication may be a PRACH preamble transmitted from the UE 10. The indicationmay further indicate one or more beams to provide system information to the UE 10.Action 303. The radio network node 12 selects the subset of SSB beams out of the set ofSSB beams, which subset of SSB beams corresponds to the received indication. The PRACHpreamble, or a RO of the transmitted PRACH preamble, indicates, or corresponds to, one or more SSB beams. Action 304. The radio network node 12 transmits the requested system information in the subset of SSB beams. It is further herein disclosed a system comprising a UE and a radio network node configured to perform the methods herein.

This configuration may be provided to the UE 10 by an assisting second radio network node (not the first radio network node 12 that transmits SIB1 on-demand). Moreover, the configuration may be provided by the second NW node to the UE 10 before the UE 10 can send the indication to the first radio network node. It is with this configuration that the UE knows how to send the indication. The configuration may comprise RACH configuration comprisingparameters indicating the mapping information, how many SSB beams are assigned to each RO,the time / frequency resource of those ROs, and / or how many preambles are available for eachSSB. The UE 10 may obtain UL WUS configuration by following methods: The UE 10 may receivethe configuration from a coverage cell, or the UE may receive the configuration from an NES cell.The configuration may indicate a PRACH resource for performing on-demand SIB1 (WUS) request either via a single message (MSG1 / preamble-based) request, or the PRACH resource is used foran initial access step out of a multi-step SIB1 request (MSG3-based). Mapping information mayrelate the indication to the corresponding SSB beam subset. The mapping information maydescribe the mapping between SSB and RACH Occasion, and / or the mapping between SSB and sent preamble or preambles. For example, the mapping information may comprise a parameter "ssb-perRACH-OccasionAndCB-PreamblesPerSSB" that describes the mapping between SSB andRACH Occasion, and / or the mapping between SSB and sent preamble or preambles.Action 402. The UE 10 transmits to the radio network node 12 the indication indicating therequest for system information, such as a PRACH preamble from a UE. The indication furtherindicates the subset of SSB beams out of the set of SSB beams to provide system information tothe UE 10. The indication may comprise the PRACH preamble, and / or the RACH occasioncorresponding to a received SSB transmission without an SIB1. Another example, the UE 10 mayin MSG3 (if a MSG3-based on-demand SIB1 request is used) the indication specifying in whichbeams the UE 10 wants to have SIB1 provided. The UE 10 may send a preamble for WUS to theradio network node 12. For example, the UE 10 may send a preamble to a coverage cell based on the RACH configuration of coverage cell, or the UE 10 may send preamble to a NES cell based onthe RACH configuration of NES cell. The preamble may be special / reserved by the radio networknode 12 for WUS.Action 403. The UE 10 may receive from the radio network node 12, the selectionindication indicating the selected, at the radio network node 12, subset of SSB beams.Action 404. The UE 10 may receive the requested system information from the radio network node 12 in the subset of SSB beams. The UE 10 may receive the requested systeminformation in the indicated and / or selected one or more beams. The requested system informationmay comprise an SIB1.The method actions performed by the radio network node 12 for handling communication in the wireless communication network 1 according to embodiments herein will now be described with reference to a flowchart depicted in Fig.5. Optional actions are marked as dashed boxes. Action 501. The radio network node 12 may transmit the configuration to the UE 10. Thismay be performed by another radio network node. The configuration may comprise RACHconfiguration comprising parameters indicating the mapping information, how many SSB beamsare assigned to each RO, the time / frequency resource of those ROs, and / or how many preamblesare available for each SSB. Mapping information may relate the indication to the correspondingSSB beam subset. The mapping information may describe the mapping between SSB and RACH Occasion, and / or the mapping between SSB and sent preamble or preambles. For example, the mapping information may comprise a parameter "ssb-perRACH-OccasionAndCB- PreamblesPerSSB" that describes the mapping between SSB and RACH Occasion, and the mapping between SSB and sent preamble or preambles. Action 502. The radio network node 12 receives, from the UE 10, the indication indicatingthe request for system information. The indication may request provision of SIB1. The indicationmay further indicate one or more beams to provide the system information to the UE 10. Forexample, the UE 10 may in MSG3 (if a MSG3-based on-demand SIB1 request is used) specify inwhich beams the UE 10 would like to have SIB1 provided. Thus, the indication or anotherindication, received in a MSG3, may further indicate one or more beams to provide the requestedsystem information to the UE. The indication may comprise a PRACH preamble from the UE 10and / or a RACH occasion used for the request. Action 503. The radio network node 12 selects the subset of SSB beams out of the set ofSSB beams, wherein the subset of SSB beams corresponds to the received indication. The radionetwork node 12 may select the subset of SSB beams based on a direction towards the UE 10and / or a location of the UE 10. The radio network node 12 may estimate the direction of the UE 10.For example, the radio network node 12 may estimate the direction through received RO, PRACHresource, and the SSB-RO mapping; through the preamble that has been assigned to a specificSSB; through location and / or direction estimation of the preamble transmission using a multi-antenna receiver; and / or through location and / or direction estimation of the MSG3 (if MSG3-basedon-demand SIB1 request is used) transmission using a multi-antenna receiver. The radio network node 12 may estimate the UE location and may send on-demand SIB1 via coverage cell or NEScell. The radio network node 12 may estimate the direction towards the UE 10 and / or location ofthe UE 10, and the subset may be selected based on the direction and / or location of the UE 10.The indication may comprise a PRACH preamble from the UE 10 and / or a RACH occasion usedfor the request and the subset of SSB beams is selected by using a mapping between SSBs and aPRACH preambles and / or RACH Occasions. That is, the received PRACH preamble or the ROused for the request corresponds to one or more SSBs. The radio network node 12 may select the subset of SSB beams by further selecting one or more additional SSB beams with a spatial neighbor relationship to a SSB mapped to the received indication. The indication or another indication, received in a MSG3 message, may further indicate the one or more SSB beams to provide the requested system information to the UE 10. Action 504. The radio network node 12 may transmit, to the UE 10, the selection indicationindicating the selected subset of SSB beams.Action 505. The radio network node 12 transmits the requested system information in thesubset of SSB beams. The radio network node 12 may thus transmit the system information bytransmitting on-demand SIB1 in a set of one or more SSB beams. In some examples, the set ofone or more beams may be given by mapping information such as a mapping function which maytake the estimated location of the UE as input and provide the set of beams as output. The radio network node 12 may transmit on-demand SIB1 in a set of one or more beams. The examples ofthe mapping information or the mapping function are given as follows:a. The set of one or more beams is given by a beam which the UE is covered by.b. The set of one or more beams is given by multiple beams, one of which covers theUE. c. The set of one or more beams is given by one beam which the UE is covered byand multiple beams (not all beams), one of which covers the UE. d. The set of one or more beams is given by beam or beams where NW predicts orexpects a UE / UEs should / could appear. e. The set of one or more beams is given by additional SSB beam coverage areas,e.g., those spatially neighboring the SSB beams directly mapped to the received RO. f. The set of one or more beams where the on-demand SIB1 is transmitted is a subsetof beams where UE presence likelihood exceeds a threshold. g. On-demand SIB1 transmission is omitted in a subset of beams where UE presencelikelihood is below a threshold. h. The set of one or more beams where the on-demand SIB1 is provided comprisesthe beam(s) which potentially were specified by the UE as part of the MSG3 (if a MSG3-based on-demand SIB1 request is used). The radio network node 12 may transmit on-demand SIB1 in specific beam or beams,and / or in all beams based on whether a criterion is fulfilled. The radio network node 12 may transmit on-demand SIB1 in specific beam / beams all the time. The radio network node 12 may transmit on-demand SIB1 in specific beam / beams and in all beams in some kind of order. Theradio network node 12 may transmit on-demand SIB1 in specific beam, beams and / or in all beamsbased on whether a criterion is fulfilled. The condition may be related to an active time, a counter, and / or an algorithm. For example, an active time may be attached, which controls the on / off switching of the specific beam / beams’ mode or all beams mode, wherein the active time is part of the criterion. A counter may be attached, which controls the on / off switching of the specific beam / beams’ mode or all beams mode, wherein the counter is part of the criterion. The switch between SIB1 transmission in specific beam / beams and all beams may be based on an algorithm,e.g., trigger by a threshold or energy saving strategy, etc being a part of the criterion. Thealgorithm may be based on network energy strategy. E.g., if the network is in energy saving mode being part of the criterion, the radio network node 12 may activate SIB1 transmission in specific beam / beams. Otherwise, the radio network node 12 may transmit SIB1 in all beams. The switch between SIB1 transmission in specific beam / beams and all beams may be based on whether SIB1 is provided only to the requesting UE 10 or made available to all UEs in the cell. The radio networknode 12 may transmit within a response message, e.g., Radom Access Responses (RAR), to theindication such as a WUS and / or on-demand-SIB1 request, specify or provide indications, alsoreferred to as selection indication or indications, (indicating one or more of preconfiguredconfigurations) of one or more of: -Which selected beams the SIB1 will be / is provided.- And per one or more selected beams, further:^ Time / frequency information related to SIB1 provision within specified beam(s), such as:- starting time;- for how long, or during what time SIB1 will be provided; and / or- Search-space / CORESET where SIB1 will be transmitted.If the UE 10 is requested to send the WUS for on-demand SIB1 through a RACH resource,the UE 10 can acquire a RACH configuration, the RACH configuration containing parametersindicating how many SSB beams are assigned to each RO, and the time and / or frequencyresource of those ROs. The UE 10 may also receive indication, or retrieve indication from a RACHconfiguration, indicating how many preambles are available for each SSB from ssb-perRACH-OccasionAndCB-PreamblesPerSSB. The UE 10 may send a preamble in a RO corresponding to a specific SSB. The UE 10 mayalso pick up a preamble, which is assigned to that SSB and send it in a RO if the RO is mapped tomultiple SSBs. An example is given in Fig.6. Fig. 6 shows an illustration of SSB to RO mappingand a corresponding preamble. The UE 10 transmits an UL WUS to / in a RO 0. RO 0 is mapped toSSB 0. In another embodiment, a RO used for a request is mapped to multiple SSBs. In this case,a part of preambles is assigned to these SSBs, and the UE 10 sends a preamble based on the SSB index, as shown in Fig.7. Fig.7 shows an illustration of SSB to RO mapping and preamblesassignment. The UE 10 transmits an UL WUS to a RO 0. RO 0 is mapped to SSB 0 and SSB1In another embodiment, a subset of the preambles that has been assigned to specific SSBs need to be picked for UL WUS of on-demand SIB1, as shown in Fig.8. Fig.8 shows an illustrationof SSB to RO mapping, preambles assignment and UL WUS. Thus, when the UE sends UL WUSwith on-demand SIB1 request, the UE may select a preamble that is associated to a specific SSB, as shown in Fig.8. Fig.8 shows a Network node, Cell A, with four SSB beams. In the time- frequency grid, there are two RO configured. The first RO is associated with SSB beam 0 / 1 and the second RO is associated with SSB beam 2 / 3. Within the first RO, a first set of preambles are associated with SSB beam 0 (SSB0) and a second set of preambles with SSB beam 1 (SSB1). Similarly, the second RO is also split into two groups of preambles. In yet another embodiment, there is no preamble assigned to SSBs although a RO is mapped to multiple SSBs. In this case, the on-demand SIB1 is sent through all those SSB beams that are mapped to this RO. Once the radio network node 12 receives the preamble, it classifies the beam which the UE 10 is located in. Then radio network node 12 may then transmit the on-demand SIB1 through thatbeam or multiple beams, one of which covers the UE 10. In one embodiment, the UE 10 sends thepreamble to a cell and the on demand-SIB1 is provided by the same cell, as shown in Fig.9. Fig.9 shows an example of beamformed on-demand SIB1 where the same cell receives UL WUS and provides the on-demand SIB1. In another embodiment, the UE 10 sends the preamble to a coverage cell and the on demand-SIB1 is provided by a NES cell. There is information exchange between the coverage cell and NES cell to infer the location of the UE and the NES cell provides on-demand SIB1 throughthe beam / beams that cover the coordinate, i.e., the location, of the UE, as shown in Fig. 10. Fig.10 shows an example of beamformed on-demand SIB1 where the coverage cell receives UL WUS, and a NES cell provides on-demand SIB1. Fig.10 A: on-demand SIB1 is provided in one beam, and Fig.10 B: on-demand SIB1 is provided in multiple beams. When the radio network node 12, e.g., a NES cell radio network node or a coverage cell radio network node, has received the preamble, the radio network node 12 uses the received preamble properties, such as RO or other resource parameters, e.g., time, frequency, rootsequence, cyclic shift etc., to determine which SSB beams are mapped to the preamble. The usedmapping is the same as configured for the UE 10. The radio network node 12 then transmits SIB1 in one or more spatial configurations corresponding to one or more SSB beams mapped to the received preamble. In one class of embodiments, the radio network node 12 transmits the SIB1 in additionalSSB beam directions, where the additional beams may be spatially neighboring or otherwise spatially close to the SSB beams derived from the preamble mapping. In addition to the received preamble-to-SSB mapping, the radio network node 12 may useadditional metrics beyond the SSB-RO mapping to determine the location or direction of therequesting UE 10. For example, the radio network node 12 may estimate the direction of the UE 10based on multi-antenna receiver beamforming during preamble reception and potentially includingmore than one message in the UL direction. For example, if a MSG3-based on-demand SIB1request is used and also additionally including an UL RRC message in the steps after thepreamble transmission in UL and preamble response in the DL by the NW. Such location and / or direction estimate may be used to more accurately estimate the relevant SSB beams where the SIB1 should be transmitted, and the radio network node 12 may transmit the SIB1 only in a subsetof multiple mapped SSB beams. The direction and / or location estimate may be used to estimatethe likelihood of the UE 10 being in a given SSB beam, and the SIB1 may be transmitted in that beam only if the likelihood exceeds a threshold. Fig.11 shows an example of on-demand SIB1 provision switching between specific beamand all beams. The radio network node 12 may switch states when providing on-demand SIB1between specific beam and all beams provision. The switching may be triggered by differentfactors and / or conditions, such as the time of day, event duration, energy saving strategy, on-offtimer, etc., as shown in Fig.11.

The radio network node 12 may estimate the UE location and send on-demand SIB1 viaa. coverage cellb. NES cell4. The UE 10 may in MSG3 (if a MSG3-based on-demand SIB1 request is used) specify inwhich beams it would like to have SIB1 provided. 5. The radio network node 12 may send on-demand SIB1 in a set of one or more beams. Theset of beams is given by a mapping function that takes the estimated location of the UE 10as input and provides the set of beams as output. The examples of mapping functions are given as follows: i. The beam which the UE 10 is covered by.j. Multiple beams, one of which covers the UE 10.k. Between one beam which the UE 10 is covered by and multiple beams (not allbeams), one of which covers the UE 10.l. Beam or beams where the radio network node 12 may predict or expect a UE / UEsshould and / or could appear.m.

On-demand SIB1 transmission is omitted in a subset of beams where UE presencelikelihood is below a threshold. p. On-demand SIB1 is provided in the beam(s) which potentially were specified by theUE as part of the MSG3 (if a MSG3-based on-demand SIB1 request is used)6. The radio network node 12 may send on-demand SIB1 in specific beam / beams all the time.7. The radio network node 12 may send on-demand SIB1 in specific beam / beams and in allbeams in some kind of orders. a. An active time is attached, which controls the on / off switching of the specificbeam / beams’ mode or all beams mode. b. A counter is attached, which controls the on / off switching of the specificbeam / beams’ mode or all beams mode.8. The switch between SIB1 transmission in specific beam / beams and all beams may bebased on an algorithm, e.g., trigger by a threshold or energy saving strategy, etc.9. The algorithm may also be based on NW energy strategy. E.g., if the NW is in energysaving mode, the radio network node 12 may activate SIB1 transmission in specific beam / beams. Otherwise, the radio network node 12 transmits SIB1 in all beams.10. The switch between SIB1 transmission in specific beam / beams and all beams may bebased on whether SIB1 is provided only to the requesting UE or made available to all UEs in the cell.11. The radio network node 12 may within the response message, e.g., RAR, to the WUS / on-demand-SIB1 request specify or provide selection indications (indicating one or more of preconfigured configurations) of one or more of: a. Which beams the SIB1 will be / is provided.b. And per one or more beams, further:i.

In some embodiments a more general term “network node” is used and it can correspond toany type of radio-network node or any network node, which communicates with a UE and / or withanother network node. In some embodiments the non-limiting term wireless device or user equipment (UE) is used and it refers to any type of wireless device communicating with a network node and / or with anotherwireless device in a cellular or mobile communication system. Examples of UE are target device,device to device (D2D) UE, proximity capable UE (aka ProSe UE), IoT capable device, machine type UE or UE capable of machine to machine (M2M) communication, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. Embodiments are applicable to any RAT or multi-RAT systems, where the wireless device receives and / or transmit signals (e.g. data) e.g. NR, Wi-Fi, LTE, LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile communications / enhanced Data rate for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMax), or Ultra Mobile Broadband (UMB), just to mention a few possible implementations. Fig.14 shows an example of a communication system 15100 in accordance with someembodiments. In the example, the communication system 15100 includes a telecommunications network 15102 that includes an access network 15104, such as a radio access network (RAN), and a core network 15106, which includes one or more core network nodes 15108. The access network 15104 includes one or more access network nodes or base stations of various types, access network nodes 15110A and 15110B are depicted (which may be collectively referred to as network nodes 15110 or radio network node 12), or any other similar 3rdGeneration Partnership Project (3GPP) access nodes or non-3GPP access points (APs). Some embodiments of the access network 15104 may include more than one access network technology. The network nodes 15110 of access network 15104 facilitate direct or indirect connection of wireless devices, also referred to as UEs, such as by connecting UEs 15112A, 15112B, 15112C, and 15112D (one or more of which may be generally referred to as UEs 15112 or UE 10) to the core network 15106 over one or more wireless connections. Moreover, a network node is not necessarily limited to an implementation in which a radio portion and a baseband portion are supplied and integrated by a single vendor. Thus, it will beunderstood that network nodes include disaggregated implementations or portions thereof. Forexample, in some embodiments, the telecommunications network 15102 includes one or more Open-RAN (ORAN) network nodes. An ORAN network node is a network node in the telecommunications network 15102 that supports an ORAN specification (e.g., a specification published by the O-RAN Alliance, or any similar organization) and may operate alone or together with other network nodes to implement one or more functionalities of any network node in the telecommunications network 15102, including one or more access network nodes 15110 and / or core network nodes 15108 such as first / second network node. Examples of an ORAN network node include an open radio unit (O-RU), an open distributed unit (O-DU), an open central unit (O-CU), including an O-CU control plane (O-CU-CP) or an O-CU user plane (O-CU-UP), a RAN intelligent controller (near-real time or non-real time) hosting software or software plug-ins, such as a near-real time control application (e.g., xApp) or a non-real time control application (e.g., rApp), or any combination thereof (the adjective “open” designating support of an ORAN specification). An ORAN network node may support a specification by, for example, supporting an interface defined by the ORAN specification, such as an A1, F1, W1, E1, E2, X2, Xn interface, an open fronthaul user plane interface, or an open fronthaul management plane interface. Moreover, an ORAN network node may be a logical node ina physical node. Furthermore, an ORAN network node may be implemented in a virtualizationenvironment (described further below) in which one or more network functions are virtualized. Forexample, the virtualization environment may include an O-Cloud computing platform orchestrated by a Service Management and Orchestration Framework via an O-2 interface defined by the O-RAN Alliance or comparable technologies.The network nodes 15110 facilitate direct or indirect connection of one or more UEs 15112 to the core network 15106 over one or more wireless connections. Example wireless communications over a wireless connection include transmitting and / or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and / or other types of signals suitable for conveying information without the use of wires, cables, or other material conductors. Moreover, in different embodiments, the communication system 15100 may include any number of wired or wireless networks, network nodes, UEs, and / or any other components or systems that may facilitate or participate in the communication of data and / or signals whether via wired or wireless connections. The communication system 15100 may include and / or interface with any type of communication, telecommunication, data, cellular, radio network, and / or other similar type of system. The UEs 15112 may be any of a wide variety of communication devices, including wireless devices arranged, configured, and / or operable to communicate wirelessly with the network nodes 15110 and other communication devices. Similarly, the network nodes 15108, 15110 are arranged, capable, configured, and / or operable to communicate directly or indirectly (e.g., via other devices of telecommunications network 15102) with the UEs 15112 and / or with other network nodes or equipment in the telecommunications network 15102 to enable and / or provide network access, such as wireless network access, and / or to perform other functions, such as administration in the telecommunications network 15102. More specifically, UEs 15112 may send messages, data, and / or other signals to network nodes 15108, 15110 or other elements of the telecommunications network 15102 by transmitting such signals to the relevant device directly without the signals passing through any intervening devices or by transmitting such signals to the relevant device indirectly through an intervening device (or multiple intervening devices) that then transmit the signal to the relevant device. Similarly, network nodes 15108, 15110 may send messages, data, and other signals to UEs 151122, other network nodes 15108, 15110, and other devices in telecommunications network 15102 directly or indirectly. As one specific example, a core network node 108 may transmit a particular message to a UE 15112 by transmitting the message to an access network node 15110 that will then transmit the message to the intended UE 15112.Similarly, a core network node 108 may receive a particular message from a UE 15112 byreceiving the message from an access network node 15110 that itself received the message from the UE 15112. In the depicted example, the core network 15106 connects elements of the access network 15104 (e.g., one or more of the network nodes 15110) to one or more host computing systems, such as host 15116. These connections may be direct or indirect via one or more intermediary networks or devices. In other examples, network nodes may be directly coupled to hosts. The core network 15106 includes one or more core network nodes (e.g., core network node 15108) of various types, one or more of which may be generally referred to as network nodes 15108. Network nodes 15108 are structured with hardware and software components. Features of these components may be substantially similar to those described with respect to the UEs, access network nodes, and / or hosts, such that the descriptions thereof are generally applicable to thecorresponding components of the core network node 15108. Example core network nodes providefunctions of one or more of a Mobile Switching Center (MSC), Mobility Management Entity (MME), Home Subscriber Server (HSS), Access and Mobility Management Function (AMF), Session Management Function (SMF), Authentication Server Function (AUSF), Subscription Identifier De- concealing function (SIDF), Unified Data Management (UDM), Security Edge Protection Proxy (SEPP), Network Exposure Function (NEF), and / or a User Plane Function (UPF). The host 15116 may be under the ownership or control of a service provider other than an operator or provider of the access network 15104 and / or the telecommunications network 15102. The host 15116 may be operated by the service provider or on behalf of the service provider. The host 15116 may host a variety of applications to provide one or more service. Examples of such applications include live and pre-recorded audio / video content, data collection services such as retrieving and compiling data on various ambient conditions detected by a plurality of UEs, analytics functionality, social media, functions for controlling or otherwise interacting with remote devices, functions for an alarm and surveillance center, or any other such function performed by a server. As a whole, the communication system 15100 of Figure 14 enables connectivity between the UEs, network nodes, and hosts. In that sense, the communication system 15100 may beconfigured to operate according to predefined rules or procedures, such as specific standards thatinclude, but are not limited to: Global System for Mobile Communications (GSM); Universal Mobile Telecommunications System (UMTS); Long Term Evolution (LTE), and / or other suitable 2G, 3G, 4G, 5G standards, or any applicable future generation standard (e.g., 6G); wireless local area network (WLAN) standards, such as the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards (Wi-Fi); and / or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (Wi-Max), Bluetooth, Z-Wave, Near Field Communication (NFC) ZigBee, Li-Fi, and / or any low-power wide-area network (LPWAN) standardssuch as LoRa and Sigfox. Moreover, the communication system 15100 may be configured tosupport multiple different standards, protocols, or other rule sets, with individual components supporting all of the relevant rule sets or with different components or sub-systems within the communication system 15100 supporting different standards, protocols, or rule sets. As one example, in certain embodiments, access network 15104 may contain some access network nodes 15110 that support 3GPP radio access technologies (RAT), such as LTE or NR, while other access network nodes 15110 support (or the same access network nodes 15110 additionally support) non-3GPP RATs, such as Wi-Fi or a proprietary RAT. As another example, telecommunications network 15102 may support multiple generations of related communication standards, e.g., 4G and 5G 3GPP communication standards, and, as a result, may include an access network 104 and / or a core network 106 that supports multiple different standard generations or may include multiple access networks 104 and / or multiple core networks 106 with individual networks 104, 106 supporting different standard generations. Telecommunications network 15102 may support network slicing to provide different logical networks to different devices that are connected to the telecommunications network 15102. For example, the telecommunications network 15102 may provide Ultra Reliable Low Latency Communication (URLLC) services to some UEs, while providing Enhanced Mobile Broadband (eMBB) services to other UEs, and / or Massive Machine Type Communication (mMTC) / Massive IoT services to yet further UEs. In some examples, one or more of the UEs 15112 are configured to transmit and / or receive information without direct human interaction. For instance, a UE may be designed to transmit information to the access network 15104 on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the access network 15104. Additionally,a UE may be configured for operating in single- or multi-RAT or multi-standard mode. For example,a UE may operate with any one or combination of Wi-Fi, NR (New Radio) and LTE, i.e. being configured for multi-radio dual connectivity (MR-DC), such as E-UTRAN (Evolved-UMTSTerrestrial Radio Access Network) New Radio – Dual Connectivity (EN-DC).In the example, the hub 15114 communicates with the access network 15104 to facilitate indirect communication between one or more UEs (e.g., UE 15112C and / or 15112D) and network nodes (e.g., network node 15110B). In some examples, the hub 15114 may be a controller, router, content source and analytics, or any of the other communication devices described herein regarding UEs. For example, the hub 15114 may be a broadband router enabling access to the core network 15106 for the UEs. As another example, the hub 15114 may be a controller that sends commands or instructions to one or more actuators in the UEs. Commands or instructions may be received from the UEs, network nodes 15110, or by executable code, script, process, or other instructions in the hub 15114. As another example, the hub 15114 may be a data collector that acts as temporary storage for UE data and, in some embodiments, may perform analysis or other processing of the data. Asanother example, the hub 15114 may be a content source. For example, for a UE that is a VRheadset, display, loudspeaker or other media delivery device, the hub 15114 may retrieve VR assets, video, audio, or other media or data related to sensory information via a network node, which the hub 15114 then provides to the UE either directly, after performing local processing, and / or after adding additional local content. In still another example, the hub 15114 acts as a proxy server or orchestrator for the UEs, in particular if one or more of the UEs are low energy IoT devices. The hub 15114 may have a constant / persistent or intermittent connection to the network node 15110B. The hub 15114 may also allow for a different communication scheme and / or schedule between the hub 15114 and UEs (e.g., UE 15112C and / or 15112D), and between the hub 15114 and the core network 15106. In other examples, the hub 15114 is connected to the core network 15106 and / or one or more UEs via a wired connection. Moreover, the hub 15114 may be configured to connect to an M2M service provider over the access network 15104 and / or to another UE over a direct connection. In some scenarios, UEs may establish a wireless connection with the network nodes 15110 while still connected via the hub 15114 via a wired or wirelessconnection. In some embodiments, the hub 15114 may be a dedicated hub – that is, a hub whoseprimary function is to route communications to / from the UEs from / to the network node 15110B. Inother embodiments, the hub 15114 may be a non-dedicated hub – that is, a device which iscapable of operating to route communications between the UEs and network node 15110B, but which is additionally capable of operating as a communication start and / or end point for certain data channels. Figure 15 shows a wireless device 15300, which may be configured to operate incommunication system 15100 of Figure 14. The wireless device 15300 may be alternativelyreferred to as a UE 15300, like a UE 15112 or the UE 10 within the context of communicationsystem 15100, or as a station (STA) 15300 or as a non-access-point station (non-AP STA) 15300, in accordance with respective embodiments. As used herein, a wireless device refers to a device capable, configured, arranged and / or operable to communicate wirelessly with network nodes and / or other wireless devices.

A wireless device 15300 may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, Dedicated Short-Range Communication (DSRC), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), or vehicle-to- everything (V2X). In other examples, wireless device 15300 may not necessarily have a user in the sense of a human user who owns and / or operates the relevant device. Instead, wireless device 15300 may represent a device that is intended for sale to, or operation by, a human user but which may not, or which may not initially, be associated with a specific human user (e.g., a smart sprinkler controller). Alternatively, wireless device 15300 may represent a device that is not intended for sale to, or operation by, an end user but which may be associated with or operated for the benefit of a user (e.g., a smart power meter).

For example, the processing circuitry 15302 may include multiple central processing units (CPUs). In the example, the input / output interface 15306 may be configured to provide an interface or interfaces to an input device, output device, or one or more input and / or output devices. Examples of an output device include a speaker, a sound card, a video card, a display, a monitor, a printer, an actuator, an emitter, a smartcard, another output device, or any combination thereof. An input device may allow a user to capture information into wireless device 15300.

The presence-sensitive display may include a capacitive or resistive touch sensor to sense input from a user. A sensor may be, for instance, an accelerometer, a gyroscope, a tilt sensor, a force sensor, a magnetometer, an optical sensor, a proximity sensor, a biometric sensor, etc., or any combination thereof. An output device may use the same type of interface port as an input device. For example, a Universal Serial Bus (USB) port may be used to provide an input device and an output device. In some embodiments, the power source 15308 is structured as a battery or battery pack. Other types of power sources, such as an external power source (e.g., an electricity outlet), photovoltaic device, or power cell, may be used to supply power to circuitry or to charge an associated battery. The power source 15308 may further include power circuitry for delivering power from the power source 15308 itself, and / or an external power source, to the various parts of wireless device 15300 via input circuitry or an interface such as an electrical power cable.

In one example, the memory 15310 includes one or more programs 15314, such as anoperating system, web browser application, a widget, gadget engine, or other application, and corresponding data 15316. The memory 15310 may store, for use by wireless device 15300, any of a variety of various operating systems or combinations of operating systems. The memory 15310 may be configured to include a number of physical drive units, such as redundant array of independent disks (RAID), flash memory, USB flash drive, external hard disk drive, thumb drive, pen drive, key drive, high-density digital versatile disc (HD-DVD) optical disc drive, internal hard disk drive, Blu-Ray optical disc drive, holographic digital data storage (HDDS) optical disc drive, external mini-dual in-line memory module (DIMM), synchronous dynamic random access memory (SDRAM), external micro-DIMM SDRAM, smartcard memory such as tamper resistant module in the form of a universal integrated circuit card (UICC) including one or more subscriber identity modules (SIMs), such as a USIM and / or ISIM, other memory, or any combination thereof.

An article of manufacture, such as one utilizing a communication system may be tangibly embodied as or in the memory 15310, which may be or comprise a device-readable storage medium. The processing circuitry 15302 may be configured to communicate with an access network or other network via or using the communication interface 15312. The communication interface 15312 may comprise one or more communication subsystems and may include or be communicatively coupled to an antenna 15322. The communication interface 15312 may include one or more transceivers used to communicate, such as by communicating with one or more remote transceivers of another device capable of wireless communication (e.g., another wireless device or a network node in an access network). Each transceiver may include a transmitter 15318 and / or a receiver 15320 appropriate to provide network communications (e.g., optical, electrical, frequency allocations, and so forth). Moreover, the transmitter 15318 and receiver 15320 may be coupled to one or more antennas (e.g., antenna 15322) and may share circuit components, software or firmware, or alternatively be implemented separately.

In particular embodiments, wireless device 15300 may provide an output of data captured via a sensor, through its communication interface 15312, via a wireless connection to a network node, and / or in any appropriate manner. Data captured by sensors of a wireless device 15300 can be communicated through a wireless connection to a network node via another wireless device 15300. In particular embodiments, such output may be periodic (e.g., once every 15 minutes if it reports the sensed temperature), random (e.g., to even out the load from reporting from several sensors), in response to a triggering event (e.g., when moisture is detected an alert is sent), in response to a request (e.g., a user initiated request), or a continuous stream (e.g., a live video feed of a patient). As another example, wireless device 15300 comprises an actuator, a motor, or a switch, related to a communication interface configured to receive wireless input from a network node via a wireless connection. In response to the received wireless input the states of the actuator, the motor, or the switch may change.

In other scenarios, wireless device 15300 may represent a vehicle, such as a car, a bus, a truck, a ship and an airplane, or other equipment that is capable of monitoring and / or reporting on its operational status or other functions associated with its operation. In practice, any number of wireless devices 15300 may be used together with respect to a single use case. For example, a first wireless device 15300 might be or be integrated in a drone and provide the drone’s speed information (obtained through a speed sensor) to a second wireless device 15300 that is a remote controller operating the drone. When a user makes changes from the remote controller, the first wireless device 15300 may adjust the throttle on the drone (e.g. by controlling an actuator) to increase or decrease the drone’s speed. The first and / or the second wireless device 15300 can also include more than one of the functionalities described above. For example, wireless device 15300 might comprise the sensor and the actuator, and handle communication of data for both the speed sensor and the actuators. Figure 16 shows a network node 15400 in accordance with some embodiments. As usedherein, network node refers to equipment capable, configured, arranged and / or operable tocommunicate directly or indirectly with a UE and / or with other network nodes or equipment, in atelecommunications network. In accordance with respective embodiments, network node 15400 may be configured to operate in communication system 15100 of Figure 14, like network nodes15108 or 15110 or the radio network node 12. Examples of network nodes include, but are notlimited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)), O-RAN nodes or components of an O-RAN node (e.g., O-RU, O-DU, O-CU).

Network node 15400 may be a relay node or a relay donor node controlling arelay. Network nodes 15400 may also include one or more (or all) parts of a distributed radio base station such as centralized digital units, distributed units (e.g., in an O-RAN access node) and / or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio.

The network node 15400 may be composed of multiple distinct network entities (e.g., a NodeB entity and a RNC entity, or a BTS entity and a BSC entity, etc.), which may each have or utilize their own respective physical components. In certain scenarios in which the network node 15400 comprises multiple such entities (e.g., BTS and BSC), one or more of the separate entities may be shared among several network nodes. For example, a single RNC may control multiple NodeBs. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, the network node 15400 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate memories 15404 or portions of memory 15404 for different RATs) and some components may be reused (e.g., a same antenna 15410 may be shared by different RATs). The network node 15400 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 15400, for example GSM, WCDMA, LTE, NR, Wi-Fi (e.g., according to an IEEE 802.11 family standard), Zigbee, Z-wave, LoRaWAN, Radio Frequency Identification (RFID) or Bluetooth wireless technologies.

In some embodiments, the processing circuitry 15402 includes one or more of radio frequency (RF) transceiver circuitry 15412 and baseband processing circuitry 15414. In some embodiments, the RF transceiver circuitry 15412 and the baseband processing circuitry 15414 may be on separate chips (or sets of chips), boards, or units, such as radio units and digital units. In alternative embodiments, part or all of RF transceiver circuitry 15412 and baseband processing circuitry 15414 may be on the same chip or set of chips, boards, or units. The memory 15404 may comprise any form of volatile or non-volatile computer-readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory(ROM), mass storage media (for example, a hard disk), removable storage media (for example, aflash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and / or any other volatile or non- volatile, non-transitory device-readable and / or computer-executable memory devices that store information, data, and / or instructions that may be used by the processing circuitry 15402.

Figure 17 is a block diagram illustrating a virtualization environment 15500 in whichfunctions implemented by some embodiments may be virtualized. In the present context, virtualizing means creating virtual versions of apparatuses or devices which may include virtualizing hardware platforms, storage devices and networking resources. As used herein, virtualization can be applied to any device described herein, or components thereof, and relates to an implementation in which at least a portion of the functionality is implemented as one or more virtual components. Some or all of the functions described herein may be implemented as virtual components executed by one or more virtual machines (VMs) implemented in one or more virtual environments 15500 hosted by one or more of hardware nodes, such as a hardware computing device that operates as an access network node, UE, core network node, or host. Further, in embodiments in which a virtual node does not require radio connectivity (e.g., a core network node or host), then the node may be entirely virtualized. In some embodiments, the virtualization environment 15500 includes components defined by the O-RAN Alliance, such as an O-Cloud environment orchestrated by a Service Management and Orchestration Framework via an O-2 interface. Applications 15502 (which may alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) are run in the virtualization environment Q400 to implement some of the features, functions, and / or benefits of some of the embodiments disclosed herein. Hardware 15504 includes processing circuitry, memory that stores software and / or instructions executable by hardware processing circuitry, and / or other hardware devices asdescribed herein, such as a network interface, input / output interface, and so forth. Software maybe executed by the processing circuitry to instantiate one or more virtualization layers 15506 (also referred to as hypervisors or virtual machine monitors (VMMs)), provide VM 15508A and VM 15508B (which may be collectively referred to as VMs 15508), and / or perform any of the functions, features and / or benefits described in relation with some embodiments described herein. Thevirtualization layer 15506 may present a virtual operating platform that appears like networkinghardware to one or more of the VMs 15508. The VMs 15508 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by virtualization layer 15506. Different embodiments of the instance of a virtual appliance 15502 may be implemented on one or more of VMs 15508, and the implementations may be made in different ways. Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment. In the context of NFV, each of the VMs 15508 may be a software implementation of a physical machine that runs programs as if they were executing on a physical, non-virtualized machine. Each of the VMs 15508, and that part of hardware 15504 that executes that VM, be it hardware dedicated to that VM and / or hardware shared by that VM with others of the VMs, forms separate virtual network elements. Still in the context of NFV, a virtual network function is responsible for handling specific network functions that run in one or more of the VMs 15508 on top of the hardware 15504 and corresponds to an application 15502. Hardware 15504 may be implemented in a standalone network node with generic or specific components. Hardware 15504 may implement some functions via virtualization. Alternatively, hardware 15504 may be part of a larger cluster of hardware (e.g. such as in a data center or CPE) where many hardware nodes work together and are managed via management and orchestration 15510, which, among others, oversees lifecycle management of applications 15502. In some embodiments, hardware 15504 is coupled to one or more radio units that each include one or more transmitters and one or more receivers that may be coupled to one or more antennas. Radio units may communicate directly with other hardware nodes via one or more appropriate network interfaces and may be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station. In some embodiments, some signaling can be provided with the use of a control system 15512 which may alternatively be used for communication between hardware nodes and radio units. Although the computing devices described herein (e.g., UEs, network nodes, hosts) may include the illustrated combination of hardware components, other embodiments may comprise computing devices with different combinations of components. It is to be understood that these computing devices may comprise any suitable combination of hardware and / or software needed to perform the tasks, features, functions and methods disclosed herein. Determining, calculating, obtaining or similar operations described herein may be performed by processing circuitry, which may process information by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node, and / or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination. Moreover, while components are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, computing devices may comprise multiple different physical components that make up a single illustrated component, and functionality may be partitioned between separate components. For example, a communication interface may be configured to include any of thecomponents described herein, and / or the functionality of the components may be partitionedbetween the processing circuitry and the communication interface. In another example, non- computationally intensive functions of any of such components may be implemented in software or firmware and computationally intensive functions may be implemented in hardware. In certain embodiments, some or all of the functionality described herein may be provided by processing circuitry executing instructions stored on in memory, which in certain embodiments may be a computer program product in the form of a non-transitory computer-readable storage medium. In alternative embodiments, some or all of the functionality may be provided by the processing circuitry without executing instructions stored on a separate or discrete device-readable storage medium, such as in a hard-wired manner. In any of those particular embodiments, whether executing instructions stored on a non-transitory computer-readable storage medium or not, the processing circuitry can be configured to perform the described functionality. The benefits provided by such functionality are not limited to the processing circuitry alone or to other components of the computing device, but are enjoyed by the computing device as a whole, and / or by end users and a wireless network generally. In some embodiments a more general term “network node” is used and it can correspond to any type of radio network node or any network node, which communicates with a wireless device and / or with another network node. Examples of network nodes are NodeB, Master eNB, Secondary eNB, a network node belonging to Master cell group (MCG) or Secondary Cell Group (SCG), base station (BS), multi-standard radio (MSR) radio node such as MSR BS, eNodeB, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, Remote Radio Unit (RRU), Remote Radio Head (RRH), nodes in distributed antenna system (DAS), core network node e.g. Mobility Switching Centre (MSC), Mobile Management Entity (MME) etc., Operation and Maintenance (O&M), Operation Support System (OSS), Self-Organizing Network (SON), positioning node e.g. Evolved Serving Mobile Location Centre (E-SMLC), Minimizing Drive Test (MDT), etc. In some embodiments, the non-limiting term wireless device or user equipment (UE) is used and it refers to any type of wireless device communicating with a network node and / or withanother UE in a cellular or mobile communication system. Examples of UE are target device,device-to-device (D2D) UE, proximity capable UE (aka ProSe UE), machine type UE or UE capable of machine to machine (M2M) communication, PDA, PAD, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. The embodiments are described for 5G. However the embodiments are applicable to any RAT or multi-RAT systems, where the UE receives and / or transmit signals (e.g. data) e.g. LTE, LTE FDD / TDD, WCDMA / HSPA, GSM / GERAN, Wi Fi, WLAN, CDMA2000 etc. As will be readily understood by those familiar with communications design, functions means or modules may be implemented using digital logic and / or one or more microcontrollers, microprocessors, or other digital hardware. In some embodiments, several or all of the various functions may be implemented together, such as in a single application-specific integrated circuit (ASIC), or in two or more separate devices with appropriate hardware and / or software interfaces between them. Several of the functions may be implemented on a processor shared with other functional components of a wireless device or network node, for example. Alternatively, several of the functional elements of the processing means discussed maybe provided through the use of dedicated hardware, while others are provided with hardware forexecuting software, in association with the appropriate software or firmware. Thus, the term “processor” or “controller” as used herein does not exclusively refer to hardware capable of executing software and may implicitly include, without limitation, digital signal processor (DSP) hardware, read-only memory (ROM) for storing software, random-access memory for storing software and / or program or application data, and non-volatile memory. Other hardware, conventional and / or custom, may also be included.
