Embodiment
The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, below in conjunction with the accompanying drawings
Realization to the embodiment of the present invention is described in detail, appended accompanying drawing purposes of discussion only for reference, is not used for
Limit the embodiment of the present invention.
The embodiment of the present invention is indicated in management information bank (MIB, Management Information Base)
Information needed.Based on this, MIB is illustrated first：
Each MIB is made up of 14 bit informations position and 10 bit IDLE bits, is repeated once every 40ms,
Transmitted on BCCH (BCCH, Broadcast Control Channel).Mib information is under
Line link system bandwidth (occupy-place 3bit, allow UE to know reception bandwidth), physical mixed autonomous retransmission refer to
Show channel (PHICH, Physical Hybrid ARQ Indicator Channel) configuration information (occupy-place 3bit,
UE is set to obtain Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel)),
And (occupy-place 8bit, remaining 2bit of System Frame Number is by Physical Broadcast Channel (PBCH, Physical for System Frame Number
Broadcast Channel) the 40ms cycles collect) composition.In 3GPP R12, agreement 36.331
MIB higher level parameters are MasterInformationBlock, and its value is as shown in table 1 below, does not indicate
The parameter of three kinds of operation modes：
MasterInformationBlock
Table 1 (R12 MasterInformationBlock parameter configurations)
PHICH-Config information element
Table 2 (configuration of R12 PHICH-Config information element field parameters)
Here, phich-Duration is represented by 1bit；Phich-Resource is represented by 2bit.
In the embodiment of the present invention, analyzed by each parameter meaning to phich-Config fields in table 1,
This field can be cancelled, it is vacant go out bit it is otherwise utilized, be such as used to refer to three kinds of operation modes and/or
FDD/TDD patterns.
Fig. 1 is the parameter indicating means based on MIB of the embodiment of the present invention one, in this example based on MIB
Parameter indicating means be applied to base station side, as shown in figure 1, the parameter indicating means bag based on MIB
Include following steps：
Step 101：PHICH configuration fields in MIB are deleted, by the PHICH configuration fields
PHICH persistence parameters are configured to the first default value, and by the PHICH in the PHICH configuration fields
Resource parameters are configured to the second default value.
With reference to table 1, PHICH configuration fields refer to phich-Config fields；In PHICH configuration fields
PHICH persistence parameters refer to phich-Duration；PHICH resource parameter in PHICH configuration fields is
Refer to phich-Resource.
It is NB-IOT systems when UE does not know current system before PBCH is read in the embodiment of the present invention
During system, increase the parameter for indicating NB-IOT bandwidth values in former bandwidth field；When UE is being read
When determining current system before PBCH for NB-IOT systems, it will be used to indicate LTE in the former bandwidth field
Bandwidth field delete, from without broadcast original LTE bandwidth information；Wherein, LTE bandwidth field is deleted
And it is vacant go out bit can be used in broadcast NB-IOT bandwidth information, if NB-IOT only has a kind of bandwidth
Information, then do not broadcast the bandwidth information in MIB.
Specifically, dl-Bandwidth fields have 8bit altogether, and existing LTE system occupies 6 bit.NB-IOT
Middle to there is 1 resource block (RB, Resource Block), i.e. dl-Bandwidth is n1 situation.If
UE does not know that this system is NB-IOT systems before PBCH is read, and n1 can be placed on to last position, i.e. n100
Afterwards, dl-Bandwidth fields should include the field of n1 values.If knowing that this system is before PBCH is read
NB-IOT systems, then can delete this field, be defaulted as 1 RB, because of NB-IOT radio frequency (RF, Radio
Freqency) bandwidth only has 1 RB.
Referring to table 2, phich-Config fields are made up of two parameters, and wherein phich-Duration values are
{ normal, extended }, phich-Resource values are { oneSixth, half, one, two }.
It can analyze, be broadcasted on MIB from 36.211 of version PHY before R12 and R12
Phich-Config fields, phich-Duration field physical significances are provided by table 3 below：
Table 3 (PHICH duration in MBSFN and non-MBSFN subframes)
As seen from Table 3, when phich-Duration values are Normal, PHICH can take the 1 of subframe
Individual OFDM (OFDM, Orthogonal Frequency Division Multiplexing) symbol,
When phich-Duration values be Extended when, PHICH multicast/multicast single-frequency network network (MBSFN,
Multimedia Broadcast multicast service Single Frequency Network) account in the case of subframe
With 2 OFDM symbols, in the case of Non-MBSFN subframes, the subframe 1 and 6 under tdd mode
In only take up 2 OFDM symbols, other situations take 3 OFDM symbols.Would generally configure only makes
PHICH is sent with first OFDM symbol, accordingly even when PCFICH decodings have failed, also not
Influence PHICH decoding.But in some scenarios, such as the less cell of system bandwidth (such as 1.4MHz,
There was only 6 RB altogether), the gain of its frequency diversity cell (such as 20MHz) more larger than system bandwidth
Cell it is low.By using extended PHICH duration, the gain of time diversity can be improved, from
And improve PHICH performance.
From the above analysis, for the less cell of system bandwidth, PHICH duration are configured to
Extended, can improve time diversity gain, so as to improve PHICH performance, then for NB-IOT
For, PHICH duration are configured to extended more particularly suitable, therefore this value is given tacit consent in MIB
For extended, can be indicated without using 1bit, with it is vacant go out this field it is otherwise utilized.
For phich-Resource fields, from below equation (1)：
Wherein, Ng∈ { 1/6,1/2,1,2 } is provided by high level；Scope be from 0 to
And for NB-IOT, downlink bandwidth only has 1 RB, i.e.,So above formula (1)
Formula (2) can be changed into：
By Ng∈ { 1/6,1/2,1,2 } is substituted into after formula (2), finds NgNo matter which value of this 4 values is taken,
All it is：
So, for NB-IOT, the value of this field is nonsensical, therefore considers to delete in MIB
Except this field (if NB-IOT system configurations PHICH duration values, normal is then known equal to 1,
Extended is then known equal to 2, or NB-IOT system default PHICH duration values are some value, then write from memory
Think corresponding value), it is vacant out otherwise utilized, e.g., instruction NB-IOT three kinds of operation modes and/or
FDD/TDD patterns etc..
Step 102：The bit taken using the PHICH configuration fields indicates the information that NB-IOT is supported,
Including a variety of operation modes, FDD/TDD patterns.
In the embodiment of the present invention, a variety of operation modes that the NB-IOT is supported include：Independent Carrier Wave, guarantor
Protecting band, band are interior；The bit taken using the PHICH configuration fields indicates a variety of fortune that NB-IOT is supported
Battalion's pattern, including：
Any 2 bits taken using the PHICH configuration fields, determine four kinds of bit combination modes；
Any three kinds of bit combination modes are selected from four kinds of bit combination modes, are indicated respectively described
Independent Carrier Wave, protection band, band are interior.
Methods described also includes：
1 bit taken using the PHICH configuration fields, determines two kinds of bit combination modes；
Using described two bit combination modes, fdd mode, tdd mode are indicated respectively.
Table 4 below with it is vacant go out field do NB-IOT operation modes indicate and FDD/TDD pattern purposes,
Lower example only enumerates a kind of representation (three kinds of operation modes are represented with 2bit), and FDD/TDD patterns are by 1bit
Indicate, but be not limited to this.
