`INVENTION TITLE: System & Method of Signaling System Information
`
`DESCRIPTION OF' THE INVENTION
`
`1. Describe the disad,,antagcs of the prior art without mentioning your invention {Including any related publicly available
`documentation, such as journal articles or 11atents).
`
`In the recent years several broadband wireless technologies }.ave been developed to meet the growing number of broadband
`
`subscribers and to provide more and better applications and services. The second generation wireless communication system has
`
`been developed to provide voice services while ensuring the mobility of users. Third generation wireless communication system
`
`suppmts not only the voice service but also data service. In recent years, the fourth wireless communication system has been
`
`developed to provide l:ri.gl,-speed data service. However. currently, the fourth generaticm wireless communication system suffers fmm
`
`lack of resources to meet the growing demand for high speed data services. So fifth generation wireless communication system is
`
`being developed to meet the growing demand for h.igh speed data services, support ulira-relrabiiity and low latency applications and
`
`support massive machine type communication.
`
`In the fourth generation wireless communication system, enhanced node B (eJ\i"B) or base station in cell bmadcast system
`
`infonnation. System informaiion is s:trnctured into master information block (MIB) and a set of system infomtation blocks (SIBs).
`
`MIB coIBists of System Frnme Number (SFN), Downlink Sy&tem bandwidth and Physical Hybrid ARQ Feedback Indicator Channel
`(PHICH) configuration. JvflB is transmi1ted every 40ms. It is repeated every lOms wherein the first transmission occms in subframe
`#0 when SFM mod 4 equals zero. MIB is transmitted on physical broadcast channel. System Infonnation Block Type 1 carries cell
`indemnity, tracking area code, cell barring information, value tag (common for aH scheduling units), and scheduling inforn1ati.on of
`
`other SIBs. SIB 1 is transmitted every 80ms in subframe #5 when SFN mod 8 equals zero. SIB 1 is repeated in subfram.e#5 when
`
`SFN mod 2 equals zero. SIB l is transmitted on Physical downlink shared channel. Other SIBs (SIB 2 to SIB 19) are transmitted in
`
`System Information (Sl) message wherein scheduling info of these Sills are indicated in SIB 1. Sills having same periodicity can be
`
`transmitted in one SI message, SJ message is broadcasted on Physical downlink shared channel. Various SIBs, their usage and
`
`typical size is indicated in Table 1 below.

`
`UE acquires the system information at cell selection, cell reselection, after handover completion, after entering E-UTRA from
`
`another RAT, upon re-entering service area, upon receiving a notification (paging), and upon exceeding the maximum validity
`
`duration (3 hr). In RRC idle state, UE needs lo a<:quire MIB, SIB 1, SIB 2 to SIB 5, SIB 6 to SIB 8 (depending on RAT suppo1ted),
`
`SIB 17 (if LTE-WLAN IWK is supported), and SIB 18 to SIB 19 (if D2D is supported). In RRC connected state, UE needs to
`
`acquire MIB, SIB !., SIB 2, SIB 8 (depending on RAT supported), SIB 17 (ifLTE-\\<1~AN !WK is supported}, and SIB 18 to SIB 19
`
`(if D2D is supported). System information acquired and stored is considered invalid of value tag in received SIB 1 is different from
`
`the one in stored SI.
`
`System information can be changed and is notified as follows: Change is notified through paging message (in RRC __ IDLE or
`
`RRC_CONNF:CTED) with cause &-ysternlnfoModification to let UE know that some SI is changing in tlie next modification period.
`
`Modification period boundaries are in terms of SFN such that SFN mod modificationPeriod = 0. Change of SI only occurs at specific
`
`rndio frames, Notificatioll of changes in modification period N will be reflected in N+L SIBl also carries value tag to indicate
`change in SI. UE finds the change in SI by looking at value tag in SlBl at the end modificationPeriod (if missed checking page) or
`
`receiving paging with systeminfoModification.
`
`One of the issues in current method of transmitting system information using the MlB/SIBs is that MlB/SIBs are periodically
`
`bmadcasted irrespective ofwheiher a UE is 1here in cell or not; whether any UE in cell needs that information. In case of small ceil
`
`deployment, broadcasting all these Sills periodically is unnecessary and leads to significant wastage of resources. So an enhanced
`
`method of signaling system infomiation is needed.

`demand. First category comprises of essential system infonnation. Essential system infonnation is periodica.lly broaclcasted by
`the ce:U. UE acqui res essential system information from broadca$1ed iufomiatio11. lu order t() receive the other sy~icm
`information, UE sends random access preamble (PRACH). On receiving the random access preamble, BS transmits a random
`access responf.e and includes OL grant for transmitting the system infomiation (Sl) request message. RAR may also include
`tiuung advance and/or back off iudicator and or preamble identifier (identifies tile PRACH preamble). UE validates tltat RAR

`
`i_n one embodiment eNB may provide the requested system information for one or more ceIJs. ENB may indicate the cells for
`
`'Which system information provided in SI responSe is applicable. As a result the UE does not need to request for system
`
`informa1ion vvhcn the UE changes cell. After the cell change, if the UE docs not have system information for the new cell then
`
`UE request for system infonnation.
`
`In one embodiment of proposed invention system infornmtion (other than essential system infornmtion) can also be broadcasted
`
`by the BS. BS may indicate in broadcasted essential system infonnation whether other system information is broadcasicd or noL
`
`If not broadcasted then DE can request using the method (Figure 1) explained earlier. If broad casted then UE read broadcasted
`
`sysicm infonnati.on to acquire the required system infom1atimL In case of heterogeneous network comprises of macro cell and
`
`smaH ccHs, macro ceU may indicate that system information is broadcasted vvbe1eas small cells may indkate that system
`
`ir,fonnation is not broadcasted.
`
`In another embodiment of proposed invention BS can indicate supported Sl(s) in essential system infonnation.
`
`In one embodiment a default configuration for system infonnation can be defined which the UE uses until it obtains them from
`
`the cell.

`mapping be1w~n one 01 more system information pammeters and seivice. So on rece iving the SI request with UE iype. BS can
`
`know the system information parameters needed by UE.
`
`ln anotl1e.r embodiment of the proposed invention the UE can acquire the system infomiation as shown in Figure 6. System
`ix1formation is categorized i.nto two categories: Firsi category comprises of one or mor.-.: System infonu;ition which is
`broackasted periodically by the cell. Second category comprises of one or more system information which is prodded to UE on
`demand. First caiegcry comprises <if essential system info rmation. E:ssential system information is periodic.illy broadcasted by
`the cell. UE acquires essential system infomiation from broadcasted infonnation. 1n order to receive the other system
`iufor1m1tion, OE se11d~ random access prt:ambl.e (PRACH). O n receiving !he random access preamble, BS transmits a random
`
`access response and includes UL grant for transmitting ihe system information (SI) request message. RAR may also iricl.ude
`
`timing advance an.dior back off indicator and or preamble identifier (ident ifies the PRACH prcan:ible). UE validates thai RAR
`correspouds to PRJ-1..CH transmitted by it. If t1,e validation is successful, UE transmits SI request message i.n the UL grant. UE
`
`may noi indicate which &ys1cm infomiation is needed by lJE. The carrier on which UE sends Sr request supports only one
`seivice. UE only indicates that il needs system infomrutio1t BS provides system informal.ion for the service supported on
`
`carder. Tbere can be pre-defined mapping between cani.cr and service. A ltc rn,1tcly, service supported can be indicated in
`
`essential ~-ystem i.n.fonnation.

`
`1n tlris method of the proposed invention the l lE c,m acquire the system infonnation as shown in Figure 7. System i11fomiation
`is categorized into three categories: First category comprises of one <)r more System :information which is broadcastcd
`
`periodically by the cell. Second category coruprlses of one or more cornruon ,-ystem information which is provided to UE on
`
`dcn:iand in random access response. Third category cornpri..ses of one or more system in:fornmtion which i.s provided to UE on
`demand iu Sl-response. first category comprises of essential syslem information. Essen1fal system information is periodically
`
`broaclcasted by the cell. UE acquires essential system information from broadcasted i nfomm1ion. In order to receive the other
`common system information., UB sends nmdom access preamble (!>RACH). PRACH preamble for obtaining system informalion
`
`in RAR can be different from the PRACH for other purposes. PRACH preHm,'Jle for obtaining system information can be
`predefined or signaled by neiwork in essential. sy&ie:m. i11f.ormation. O.n receivi.ng th.e random access preamble, BS tnmsm.Hs a
`random access response and includes lJL grant for transmitting the system iufom1ation request message. RA.R inciudes the
`common system infomialion. RAR may also include timing advance and/or bacik off indicator ,md or preamble idenli:fier
`
`(identifies the PRACH preamble). UE validates that RAR corresponds to PRACH tn10smitted by it. lf the validation is
`successful, UE l:ra.nsmits SI rcquesl message in the UL grnnt to request one or more syslcm in:formali.on according to iis need. ST
`request message indicates system information or set of &)'Stem information or service or UE type. ·uE may tri!Dsmit irs UE ID
`(ic. S-TMSl, C-RNTT, RA-R.NJ.l, etc) along \~ith SI request message. In response io SI rcquesi, ErfB transmits ST-response
`
`wherein the SI-response includes the requested system information. Scheduling control information indicating the SI-response
`can be masked with UE"s ID (e.g. C-RNTI, RA-RNTT) or a pcc-ddincd ID (e.g. SI-R1'71). Pre-defined ID can be different fo.r
`
`different system in.formation or system ittforrnatic,n set or servlce or UE type. UE ca1, indicate the needed system i.nfonnation in

`Sl-Request using the options ex-plained in description of method 1.
`
`In one embodiment. eNB may provide the requested system informaticm for one or more cells. ENB may indicate the ceUs for
`which system i.J1formation provided in SI response is applicable. As a result the UE does not need to request for system
`
`information when the UE changes cell. After the cell change, if the UE does not have system information for the new cell U1en
`
`UE request for system information.
`
`In another embodiment of proposed invention system information (other than essential system information) can also be
`
`broadcastcd by the BS. BS may indicate in broadcasted essential system information whether other system infom1ation is
`broadcasted or not. If not broadcasted then UE can request using the method (figure 7) e:s.1Jlained earlier. lf broadca,1ed then
`lJE read broadcastcd system in:fonnation to acquhc the required system i.nfonnation. T.n case of heterogeneous networ.k
`
`comprises o.f macro cell and small cells, macro cell may indicate tlmt system in.fo.rmation is brcadcastcd whe.reas small cells
`may indicate that system information is not broadcasted.
`
`In another embodi.Iuent of proposed invention BS can indicate supported SI (s) in essential ~ystem infonnation.
