Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, the present invention is made below in conjunction with accompanying drawing into
One step it is described in detail, it is clear that the described embodiment only a part of embodiment of the present invention, rather than whole implementation
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belongs to the scope of protection of the invention.
As described in Figure 2, the system of reporting buffer status report of the embodiment of the present invention includes：
Terminal 10, for generating configured information according to the logic channel group for having buffer data size；According to the configured information
The order of instruction will be currently able to the buffer data size of at least one logic channel group that reports, be placed in buffer status report media
In Access Control control unit BSR MAC CE, and the configured information is placed in BSR MAC CE；To network side equipment
Reporting buffer status report.
Network side equipment 20, the buffer status report reported for receiving terminal；According to the finger of the buffer status report
Show information, determine to carry the corresponding logic channel group of buffer data size in the BSR MAC CE of the buffer status report, its
Described in configured information be that the terminal generates according to the logic channel group for having buffer data size information.
The embodiment of the present application terminal generates configured information according to the logic channel group for having buffer data size, according to the instruction
The order of information instruction will be currently able to the buffer data size of at least one logic channel group that reports, be placed in BSR MAC CE
In, and the configured information is placed in BSR MAC CE.Due to that can indicate to delay in BSR MAC CE by configured information
Logic channel group corresponding to deposit data amount, so as to meet 5G NR demands, the efficiency that caching reports is further increased, and
And save resource.
Optionally, terminal and network side can report the quantity and logic of the logic channel group of buffer data size as needed
Channel group configured information, determine the length of the BSR MAC CE.So as to which Length Indication can not be carried in MAC subheaders, when
Right BSR MAC CE length is not fixed.
That is, it is necessary to report the quantity difference of the logic channel group of buffer data size, BSR MAC CE length is not
Together, but in MAC subheaders Length Indication domain L is not needed to be used for the length for indicating elongated BSR MAC CE.
In the present invention logic channel group buffer data size report Buffer Size with 8bit and 6bit as an example,
Buffer Size can be only one kind in 8bit or 6bit in specific implementation, it is impossible to occur simultaneously.With 8bit Buffer
Exemplified by Size, the logic channel group number for reporting buffer data size if desired is K, then BSR MAC CE length is K+1.
The BSR MAC CE types of the embodiment of the present invention are divided into two kinds, every kind of to have different forms：Complete BSR MAC CE
With truncation BSR MAC CE.It is introduced separately below.
The first：Complete BSR MAC CE.
Terminal described in this mode will be currently able to the buffer data size of all logic channel groups that reports, according to the finger
Show that the order of information instruction is placed in BSR MAC CE.
In force, configured information can be used as by the use of bitmap (bit map).
If the configured information is bitmap, the corresponding logic channel group of each bit in the bitmap, and compare
Numerical value on special position indicates whether to report the buffer data size of counterlogic channel group, and logic channel group maximum number is 8, then may be used
To be used as logic channel group configured information by the use of 1byte bitmap.
Represent to report assuming that be directed to particular logical channel group, 1,0 represents not report, currently have buffer data size and need into
All logic channel groups for reporting of row caching are logic channel group 0, logic channel group 1 and logic channel group 5, then bitmap is
11000100。
The order of terminal logically channel group 0, logic channel group 1 and logic channel group 5 is by corresponding buffer data size
It is placed in BSR MAC CE.
Accordingly, if the bitmap that network side equipment receives is 11000100, it is known that in BSR MAC CE and carries
The buffer data size of logic channel group 0, logic channel group 1 and logic channel group 5.
If it is exactly to be currently able to all logics for reporting to believe to also have a kind of optimal way for complete BSR MAC CE
Road group is exactly the logic channel group of maximum number, i.e., all 8 logic channel groups will carry out caching and report, it indicates that information can
To be not present in using implicit in BSR MAC CE.
Than as shown in Figure 3A, one shares 8 logic channel groups, all logic channel groups for being currently able to report are this 8,
Then the buffer data size of this 8 logic channel groups is all placed in BSR MAC CE；
Accordingly, if not having configured information in the BSR MAC CE that network side equipment receives, BSR MAC CE are known that
In include the buffer data sizes of all logic channel groups.
Certainly, such case above carry configured information similarly can be with.
BSR MAC CE Length Indication can be carried in corresponding MAC CE subheaders for complete BSR MAC CE
Domain.
On the other hand, because the numerical value on logic channel group configured information bit indicates whether to report counterlogic channel
The buffer data size of group, the bit number that the buffer data size of each logic channel group takes is fixed, then network side equipment can
To determine that BSR MAC CE include the buffer data size of how many individual logic channel groups according to logic channel group configured information, so
Network side equipment can determine BSR MAC CE length, without individually carrying a Length Indication domain, so MAC
Length Indication domain can not be carried in head.
Second：The BSR MAC CE of truncation.
Terminal described in this mode will be currently able to the buffer data size of part logic channel group that reports, according to the finger
Show that the order of information instruction is placed in BSR MAC CE.
In force, configured information can be used as by the use of bitmap.
If the configured information is bitmap, the corresponding logic channel group of each bit in the bitmap, and compare
Numerical value on special position indicates whether to report the numerical value on the buffer data size or bit of counterlogic channel group to represent corresponding and patrolled
Collect whether channel group has buffer data size.
If the numerical value on bit indicates whether to report the buffer data size of counterlogic channel group, logic channel group quantity
It is up to 8, logic channel group instruction can be carried out with 1byte bitmap, 1 represents to report, and 0 represents not report, current energy
All logic channel groups enough reported are logic channel group 0, logic channel group 1 and logic channel group 5, and terminal presses logic channel
The BSR MAC CE sizes that group order and Current resource can accommodate, report the caching of logic channel group 0 and logic channel group 1
Data volume, then bitmap is 11000000.
Logically corresponding buffer data size is placed in BSR MAC to terminal by the order of channel group 0 and logic channel group 1
In CE.
Accordingly, if the bitmap that network side equipment receives is 1100000, it is known that in BSR MAC CE and carries
The buffer data size of logic channel group 0 and logic channel group 1.
If the numerical value on bit represents whether counterlogic channel group has buffer data size, logic channel group quantity maximum
For 8, logic channel group instruction can be carried out with 1byte bitmap, 1 indicates buffer data size, and 0 represents without caching number
According to amount, the logic channel group that terminal has buffer data size is logic channel group 0, logic channel group 1, logic channel group 2 and logic
Channel group 3, but it is logic channel group 0 and logic channel group 1 to be currently able to report the logic channel group of buffer data size amount.This example
Middle bitmap is 11110000, but truncates the buffer data size for there was only logic channel group 0 and logic channel group 1 in BSR MAC CE
Report.
Logically corresponding buffer data size is placed in BSR MAC to terminal by the order of channel group 0 and logic channel group 1
In CE.
Accordingly, if the bitmap that network side equipment receives is 11110000, logic channel group 0, logic letter are known that
Road group 1, logic channel group 2 and logic channel group 3 have buffer data size, find have two to patrol subsequently when parsing BSR MAC CE
The buffer data size of channel group is collected, is known that the caching number for including logic channel group 0 and logic channel group 1 in BSR MAC CE
According to amount, and it can also know that terminal also has logic channel group 2 and the buffer data size of logic channel group 3 not to report.
BSR MAC CE Length Indication can be carried in corresponding MAC CE subheaders for the BSR MAC CE of truncation
Domain.
On the other hand, BSR MAC CE are truncated to report as padding BSR.Network side equipment is according to MAC PDU length
The MAC PDU length of degree and other loads composition, determines MAC corresponding to the BSR MAC CE and BSR MAC CE
The MAC PDU (being referred to as MAC sub-PDU) of head composition length, wherein other loads include MAC SDU and/or removed
Other MAC CE outside BSR MAC CE.
If other loads include MAC SDU, the MAC PDU of other loads composition include MAC SDU and its corresponding
MAC subheaders；
If other loads include other MAC CE in addition to BSR MAC CE, MAC of other loads composition
PDU includes other MAC CE and its corresponding MAC subheaders in addition to BSR MAC CE；
If other loads include MAC SDU and other MAC CE in addition to BSR MAC CE, other load groups
Into MAC PDU include MAC SDU and its corresponding MAC subheaders, and including other MAC in addition to BSR MAC CE
CE and its corresponding MAC subheaders.
For example, each MAC PDU can include 1 MAC SDU and its corresponding MAC subheaders, each MAC PDU can be with
Including other MAC CE of 1 in addition to BSR MAC CE and its corresponding MAC subheaders.
If the numerical value on bit indicates whether to report the buffer data size of counterlogic channel group, BSR MAC CE length
Degree can also obtain BSR MAC CE length by logic channel group number corresponding to the configured information.
Based on this, network side equipment can determine BSR MAC CE length, can be not required to carry length in MAC subheaders
Instructions field.
If specifically, the MAC PDU length that network side equipment forms according to MAC PDU length and other loads, really
Determine the length of the MAC PDU of MAC subheaders composition corresponding to the BSR MAC CE and BSR MAC CE, then network side is set
After the standby MAC PDU length that other loads composition is subtracted by MAC PDU length, it may be determined that padding length.
Padding parts do not need Length Indication, when reporting truncation BSR MAC CE with padding parts, equally
Length Indication domain can not needed.
Optionally, the capacity of the buffer data size of the single logic channel in the embodiment of the present application BSR MAC CE is (i.e.
Buffer size) it is divided into two kinds of 8bit (referring specifically to Fig. 3 B) and 6bit (referring specifically to Fig. 3 C).
Under 6bit buffer size, because BSR MAC CE forms are in units of byte, except buffer size
Outside, remaining bit is then reserved bit.
The embodiment of the present application provides two kinds of BSR MAC CE form, and a kind of optional mode is in BSR MAC CE couple
The information for indicating BSR MAC CE types is carried in the MAC subheaders answered.
Specifically, terminal is by for indicating that the information of BSR MAC CE types is placed in MAC corresponding to the BSR MAC CE
In subheader；
Accordingly, the information that is used to indicate BSR MAC CE type of the network side equipment in MAC subheaders, it is determined that
Corresponding BSR MAC CE type.
The embodiments of the invention provide the side that the information for being used to indicate BSR MAC CE types is included in a variety of MAC subheaders
Formula, it is introduced separately below.
Mode one, LCID domains and CE Type combination instruction BSR MAC CE types：The content corresponding to LCID domain representations is
BSR MAC CE, the particular type of the BSR MAC CE is further indicated with another domain CE Type.
Specifically, terminal passes through MAC corresponding to 1 LCID value instruction in MAC subheaders corresponding to the BSR MAC CE
CE is BSR MAC CE, and further indicates complete BSR MAC CE with CE Type or truncate BSR MAC CE；
Accordingly, the network side equipment passes through the LCID domains determination pair in MAC subheaders corresponding to the BSR MAC CE
After the MAC CE answered are BSR MAC CE, according to CE Type specifically determine BSR MAC CE types for complete BSR MAC CE or
Truncate BSR MAC CE.
Here mode one is to indicate that MAC CE are BSR MAC CE with 1 LCID value, and specific LCID values use several bits all
Can be with, for example can represent that MAC CE are BSR MAC CE with 1, it can also represent that MAC CE are BSR MAC CE with 11；
Further indicate that BSR MAC CE type is complete or truncated with CE Type, for example can have been represented with 1
Into 0 represents to truncate；It can also represent complete with 11,10 represent to truncate.
In force, it can be indicated with whole CE Type, one or more of CE Type bit can also be used to indicate.
As shown in Figure 4 A, CE Type take 2bit in figure, can also use Fig. 4 B, such CE according to embodiments of the present invention
Type only takes up 1bit, and another bit is reserved bit.
Mode one really by LCID indicates whether it is BSR, and represents to be complete or truncation by CE Type.
For example LCID=x, expression are BSR, CE Type=1 represent complete BSR, and 0 represents to truncate BSR, then one it is complete
LCID=x in MAC subheaders corresponding to BSR MAC CE, CE Type values are 1；MAC corresponding to the BSR MAC CE of one truncation
LCID values=x in subheader, CE Type values are 0.
It should be noted that Length Indication domain L is redundancy in Fig. 4 A and Fig. 4 B, for uniform format, can also wrap
Domain containing Length Indication.Due to being not essential comprising Length Indication domain, it is represented by dotted lines in figure, that is, represents that the domain can not deposit
.
Mode two, LCID domains indicate different BSR MAC CE types：Specially inhomogeneity is represented with different LCID values
The BSR MAC CE of type.
Specifically, two LCID values in terminal MAC subheaders corresponding to the BSR MAC CE are respectively used to indicate BSR
MAC CE are complete BSR MAC CE or truncate BSR MAC CE；
Accordingly, the LCID values in network side equipment MAC subheaders according to corresponding to the BSR MAC CE determine
BSR MAC CE forms.
Here mode two is to indicate that MAC CE are complete BSR MAC CE or truncate BSR MAC CE with two LCID values,
Specific LCID values using several bits can, for example can represent that MAC CE are complete BSR MAC CE, 0 expression MAC CE with 1
To truncate BSR MAC CE；It can also represent that MAC CE are complete BSR MAC CE with 11,10 represent MAC CE to truncate BSR
MAC CE。
For example LCID=x represents that complete BSR MAC CE, LCID=y represent to truncate BSR MAC CE.Other bit can make
To reserve bit, as shown in Figure 4 C.
Mode two is really to represent that BSR MAC CE are complete BSR MAC CE or truncation BSR MAC by LCID value
CE。
For example LCID1 represents complete BSR MAC CE, LCID2 expressions truncate BSR MAC CE, then a complete BSR
LCID values in MAC subheaders corresponding to MAC CE are LCID1；In MAC subheaders corresponding to the BSR MAC CE of one truncation
LCID values are LCID0.
It should be noted that Length Indication domain L is redundancy in Fig. 4 C, for uniform format, length can also be included
Instructions field.Due to being not essential comprising Length Indication domain, it is represented by dotted lines in figure, that is, represents that the domain can be not present.
Several examples are set forth below to illustrate the solution of the present invention.
Embodiment 1：Regular (routine) BSR or periodic (cycle), BSR was reported.
End side：End side reports whole cache informations after regular BSR or periodic BSR is triggered, i.e., only
Complete BSR can be reported.
BSR MAC CE forms such as Fig. 3 A.For example, if terminal has logic channel group 0, logic channel group 2, logic
The buffer data size of channel group 4 and logic channel group 5, then specific BSR MAC CE such as Fig. 5 A (8bit Buffer Size)
Or Fig. 5 B (6bit Buffer Size).
MAC subheaders form corresponding to the BSR MAC CE is one kind in Fig. 4 A, Fig. 4 B or Fig. 4 C.Can be with MAC subheaders

Base station side：Receive the BSR that UE is sent to report, determine there is buffer data size from BSR MAC CE first character section
Logic channel group, and receive subsequent buffer data size report.Subsequent upstream scheduling is carried out to terminal accordingly.
Embodiment 2：Padding (filling) BSR reports complete cache information.
End side：Terminal is organizationally after row packet if surplus resources, also has that data are to be transmitted in terminal buffers,
But when surplus resources are not enough to accommodate a new MAC SDU, padding BSR can be organized to report, i.e., by BSR MAC CE
It is placed in padding and reports.
Given the correct time when surplus resources are large enough to hold on whole BSR, complete BSR MAC CE are reported in padding BSR.BSR
MAC CE and its head form are same as Example 1.
Base station side：After base station receives the padding BSR of terminal transmission, determine that there be upper line number waiting for transmission end side
According to accordingly to terminal progress subsequent upstream scheduling.
Embodiment 3：Truncated (truncation) BSR is reported (to be included in the current truncation BSR MAC CE of bitmap instructions
Logic channel group).
End side：Terminal is organizationally after row packet if surplus resources, also has that data are to be transmitted in terminal buffers,
But when surplus resources are not enough to accommodate a new MAC SDU, terminal can organize padding BSR to report.Work as surplus resources
It is not enough to accommodate and is given the correct time on the BSR of whole logic channel groups, is reported in padding BSR and truncate BSR MAC CE.
Bitmap only indicates the current logic channel group for truncating and being included in BSR MAC CE in the present embodiment.For example,
Such as have that the data of logic channel group 0, logic channel group 1, logic channel group 4 and logic channel group 5 are to be sent in terminal buffers,
But currently only 3byte surplus resources, then BSR MAC CE are as shown in fig. 6 a or 6b.
MAC subheaders form corresponding to truncation BSR MAC CE is one kind in Fig. 4 A, Fig. 4 B or Fig. 4 C.In MAC subheaders
There can be Length Indication domain L, can also there is no Length Indication domain L.
Base station side：After base station receives the truncation BSR MAC CE of terminal transmission, determine that end side also has on waiting for transmission
Row data can be terminal distribution more than the uplink transmission resource truncated needed for buffer data size indicated by BSR MAC CE.
Embodiment 4：Truncated BSR are reported (the logic channel group that bitmap instruction terminals all have caching).
End side：Terminal is organizationally after row packet if surplus resources, also has that data are to be transmitted in terminal buffers,
But when surplus resources are not enough to accommodate a new MAC SDU, terminal can organize padding BSR to report.Work as surplus resources
It is not enough to accommodate and is given the correct time on the BSR of whole logic channel groups, is reported in padding BSR and truncate BSR MAC CE.
Bitmap instruction terminals all have the logic channel group of caching in the present embodiment., such as terminal buffers for example
In have that the data of logic channel group 0, logic channel group 1, logic channel group 4 and logic channel group 5 are to be sent, but it is current only
3byte surplus resources, then BSR MAC CE are as shown in Fig. 7 A or Fig. 7 B.
MAC subheaders form corresponding to truncation BSR MAC CE is one kind in Fig. 4 A, Fig. 4 B or Fig. 4 C.In MAC subheaders
There can be Length Indication domain L, can also there is no Length Indication domain L.
Base station side：After base station receives the truncation BSR MAC CE of terminal transmission, determine that end side also has on waiting for transmission
Row data, and determine that terminal also has logic channel group 4 and the buffer data size of logic channel group 5 not to report, base station can be terminal
