Description
Technical field
The present invention relates to wireless communication technology, random access radio network is determined more particularly, to one kind
Temporary mark (RA-RNTI, Random Access Radio Network Temporary Identity)
Method, user equipment and base station.
Background technology
It is different in traditional communication system such as Long Term Evolution (LTE, Long-Term Evolution) system
RACH is to use different random access radio network temporary mark (RA-RNTI, Random
Access Radio Network Temporary Identity) distinguished.User equipment (UE, User
Equipment) use and send Physical Random Access Channel (PRACH, the Physical of random access guiding
Random Access Channel) corresponding RA-RNTI, carried out in follow-up accidental access response window
The reception of accidental access response (RAR, Random Access Response).During this,
The RA-RNTI that UE is used is to calculate to obtain by equation below：
RA-RNTI=1+t_id+10*f_id
Wherein, t_id is to send first subframe numbers (0≤t_id where the PRACH of random access guiding
＜ 10), f_id be the subframe send random access guiding PRACH on frequency domain index (0≤
F_id ＜ 6).For FDD, each subframe only one of which PRACH resources, therefore f_id is solid
It is set to 0.It can be seen that, traditional RA-RNTI computational methods are with subframe numbers and frequency shift (FS) serial number parameter
Calculated, could support up the identification of the PRACH in the range of a 10ms frame.
Present inventor has found during realizing that the application implements technical scheme, although traditional
RA-RNTI computational methods, which can distinguish RAR responses completely, may fall in same RAR windows
All possible PRACH, but fixation is all possible to distinguish using preceding 70 RA-RNTI values
Uses of the PRACH to RA-RNTI values is wasted a little.Because may only be lacked in systems in practice
Measure PRACH deployment.
In addition, the computational methods of this RA-RNTI values are not suitable for influenceing the factor of PRACH distributions yet
More system.Exemplified by being communicated with machinery compartment (Machine to Machine, hereinafter referred to as M2M).

Internet of Things) the sub- problem of systematic research, target is that one is built in 200KHz frequency band
Similar system, low handle up is provided for low cost terminals with Long Term Evolution (LTE, Long-Term Evolution)
The wireless communication services of amount.It is descending still to use OFDM (OFDMA, Orthogonal
Frequency Division Multiple Access) technology, it is up using still using single-carrier frequency division multiple access
(SC-FDMA, Single-Carrier Frequency Division Multiple Access) technology, and weight as far as possible
With or simplify functional module specified in existing LTE system.Subcarrier width is except continuing to use LTE system
Outside 15KHz subcarrier width, up increase 3.75KHz subcarrier width is up to further enhance
Big covering support.
Currently, related technical standard is just studied in 3GPP International Organization for standardization.3GPP
Proposed in RAN2 the 92nd meeting：Random access guiding in NB-IoT systems can be single carrier
Or multicarrier, and NB-IoT systems also need to consider different covering grades to support
A variety of covering scenes.Thus the type of the RACH of NB-IoT systems will be more complicated.Especially
It is the random access guiding of single carrier, its length may be long, may meet or exceed one
The length of 10ms frames.Moreover, in order to support enhanced covering scene, with accidental access response (RAR,
Random Access Response) need progress that transmission is repeated several times.So, in NB IoT systems
Accidental access response window may be long, or even can exceed 10ms frame length.
In NB-IoT systems, with increasing for Consideration, such as the different numbers of repetition of a variety of coverings,
PRACH types (list carrier wave and multi-subcarrier) etc., using traditional RA-RNTI computational methods
Substantial amounts of RA-RNTI values may be needed.With number of repetition 4, exemplified by type class number 2, tradition side
Method needs 560 different RA-RNTI values.This design is in UE numbers very big NB-IoT systems
Seem especially inapplicable.

By the example in several applications, the present invention will be described again below.
Example one
Fig. 5 is the signaling process that mode of this example based on mapping determines RA-RNTI values.As illustrated,
Including：
Step one, base station is also sent in addition to broadcasting PRACH distributed intelligences by broadcasting the message
The configured information of RA-RNTI determination modes, and determine the information of sortord；
For example, the configured information can be represented with 1bit, when the value of the bit is ' 1 ', RA-RNTI is represented
Value is determined by the way of based on mapping；When the value of the bit is ' 0 ', represent RA-RNTI values by biography
The calculation of system determines that this example assumes that the value of the bit is ' 1 '.To different type or form

Step 4, UE uses the RA-RNTI value determination modes based on mapping, is distributed according to PRACH
Middle PRACH and the mapping relations of RA-RNTI values, it is determined that sending PRACH pairs of random access guiding
The RA-RNTI values answered, are received for follow-up RAR.
Example two
This example is a specific example for carrying out RA-RNTI mappings.Wherein Fig. 6 A are one simple
According to different type according to time sequencing carry out PRACH sequences schematic diagram；Fig. 6 B are one simple
In the way of one-to-one mapping, the schematic diagram of corresponding RA-RNTI values is obtained according to PRACH sequence number.
As shown in Figure 6A, within the PARCH shown time cycle (totally 10 subframes), including 3
The PARCH of type：10 short PRACH (length is less than a subframe), 1 long PRACH
(length is more than a subframe) and the relatively wide PRACH of a frequency domain (using many height frequency ripples).This
In example, PARCH type priority level highest, and the order of this 3 types is：Carried using 1 son
The short PARCH of ripple, using the long PARCH of 1 subcarrier, uses the PARCH of multiple carrier waves.Class
Type identical PARCH, this example sorts according still further to the order of starting subframe from small to large, therefore, in figure
12 PARCH sequence after sequence number as illustrated, including PRACH1~PRACH10, PRACH11
And PRACH12.As shown in Figure 6B, by the PRACH of different sequence numbers successively with RA-RNTI value models
RA-RNTI values in enclosing carry out one-to-one mapping, and each PRACH corresponds to one of same sequence number
The sequence number of RA-RNTI values in RA-RNTI values, RA-RNTI spans can be according to RA-RNTI
The mode of value from small to large sorts and determined, can also be sorted by RA-RNTI values in the way of from big to small
And determine, or directly determined according to defined good sequence number.Because UE and base station are all according to identical
Mode maps, thus UE and base station can be distributed according to PRACH information, RA-RNTI value models
Enclose and determine that information of sortord etc. finds correct RA-RNTI values.
Although it should be noted that this example be using PARCH type as limit priority pair
The information of PARCH sequences, but be not limited thereto.Can also be by other information such as PARCH starting
The priority of subframe, initial frequency etc. is set to limit priority.Fig. 7 is to indicate sequence base there is provided one kind
In PRACH information priority signaling format.As illustrated, a byte can indicate 4
Individual Sort Priority parameter, wherein each priority accounts for 2 bits, indicates respectively 4 kinds of parameters from front to back：
PRACH types, PARCH starting subframe, PARCH initial frequency and PARCH covering etc.
Level (can be represented with number of repetition).And the value of 2 bit can take 00,01,10 and 11, table
The priority shown is from high to low.As illustrated, the signalling value of the priority of this example is：0001XXXX
(X is expressed as 0 or 1), represents first to press PARCH byte orderings, to same type, then by PARCH
Starting subframe sequence because in the absence of PARCH types and starting subframe all same multiple PARCH,
Therefore UE is not relevant for rear 4 bit value.The order of shown priority can also be fixed up, and
Arranged in advance by standard agreement.In addition, for the information of same priority, sort method
It is flexible and changeable.For example, on the time both can from morning to night (be specifically as follows starting subframe from it is small to
Greatly), (starting subframe can also be specifically as follows from big to small) from evening to morning；Both can be from frequency
