The 5G NR also introduces a variety of traffic types, and due to the diversification of 5G networks and functions, more MAC control units will be introduced. Each service has a corresponding logical channel number assignment, and the MAC control unit also needs to occupy the logical channel number. The current number of LCIDs cannot meet the requirement of 5G NR.
In summary, the current number of LCIDs cannot meet the requirement of 5G NR.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1A, the system for MAC control element transmission according to the embodiment of the present invention includes: a transmitting device 10 and a receiving device 20.
A sending device 10, configured to determine, according to a MAC control unit, a MAC subheader including an LCID and differentiation indication information, where the LCID and the differentiation indication information are used together to uniquely identify one MAC control unit, and MAC control units with the same characteristics multiplex the same LCID; the same characteristics are that the carried messages are of the same type and/or cannot appear at the same time; and sending the MAC PDU comprising the MAC subheader and the corresponding MAC control unit.
And the receiving device 20 is configured to receive the MAC PDU including the MAC subheader and the corresponding MAC control element from the sending device, and determine the corresponding MAC control element according to the LCID and the distinguishing indication information.
The sending equipment determines the MAC subheader containing the LCID and the distinguishing indication information according to the MAC control unit, and sends the MAC PDU containing the MAC subheader and the corresponding MAC control unit, wherein the LCID and the distinguishing indication information are used for uniquely identifying one MAC control unit. Because the embodiment of the invention uniquely identifies one MAC control unit together with the LCID and the distinguishing indication information, different MAC control units can use the same LCID, thereby identifying more MAC control units on the premise of not introducing more LCIDs and meeting the requirement of 5G NR.
the MAC control units with the same characteristics multiplex the same LCID.
wherein, the same characteristic is that the carried message types are the same, for example, different MAC control elements indicate the buffer status report information in different ways (or the indicated contents are all power headroom information, or are all used for carrier activation/deactivation, etc.), and then the MAC control elements are considered to be of the same type;
Cannot occur simultaneously as MAC CEs in one MAC PDU, such as a MAC CE for indicating MBMS information and various MAC CEs for unicast, cannot be multiplexed at one time.
In the embodiment of the invention, the MAC sub-head of the MAC CE does not need to be consistent with the MAC sub-head format of the MAC SDU, because the sending end and the receiving end can distinguish whether the MAC CE or the MAC SDU is the MAC CE or the MAC SDU through the LCID. Thus, the MAC subheader of MAC SDU and MAC subheader of MAC ce (control unit) can be separately and independently designed.
Optionally, the distinguishing indication information according to the embodiment of the present invention includes first information for distinguishing different MAC control elements in the same length type and/or second information for indicating whether there is a length indication field.
Wherein the first information is located in a message type subdivision domain of the MAC subheader;
The second information is located in an extended indication field of the MAC subheader indicating whether a length indication field exists.
In an implementation, the length type of the MAC subheader may be divided into a fixed length and a variable length.
the fixed length means that the length of the MAC CE is invariable, and the specific length and format are specified by a protocol;
the variable length means that the length of the MAC CE is variable, and may be different according to the specific contents accommodated in the MAC CE.
If only the MAC subheader of a fixed length is included in the application scenario, the embodiment of the present invention may introduce an MAC CE indication field I (i.e., a message type subdivision field), for example, the field I in fig. 1B is 2 bits, and the field bit length may be 1 to 3 bits, depending on the number of MAC CE types multiplexing the same LCID. The LCID domain in the figure is 5 bits, and can be expanded according to the actual situation, such as 6 bits.
if there are fixed-length and variable-length MAC subheaders in the application scenario, an E-field (an extended indication field indicating whether a length indication field exists) and/or an I-field may be mapped. As shown in fig. 1C.
-domain E: indicating whether an L domain exists subsequently, if so, the MAC CE is the MAC CE with the variable length in the same type of MAC CEs, and if not, the MAC CE is the MAC CE with the fixed length in the same type of MAC CEs;
-an I domain: if there are more than one fixed length or variable length MAC CE in the same type of MAC CE, it can further indicate which type of MAC CE is in the I field. The length of I can be 1-2 bits, depending on the fixed length or variable length MAC CE.
Optionally, if the length type of the MAC control element is a fixed length, the distinguishing indication information includes the first information; or
if the length type of the MAC control element is a fixed length or a variable length, the distinguishing indication information includes the first information and/or the second information.
the MAC subheader of the embodiment of the present invention includes, but is not limited to, part or all of the following:
MAC subheader for BSR (buffer status report);
a MAC subheader for PHR (power headroom report);
a MAC subheader for activation and/or deactivation indication for member carriers in CA (Carrier Aggregation);
A MAC subheader for a DRX (discontinuous reception) command;
A MAC subheader for physical layer signaling;
MAC subheader for data volume indication.
different MAC subheaders and distinguishing indication information comprise different information, and the following methods are listed as follows:
The first method comprises the following steps: the MAC subheader is a MAC subheader for a BSR or a MAC subheader for a component carrier activation and/or deactivation or a MAC subheader for a DRX command:
the MAC control units having the same characteristic include fixed-length MAC control units, and the distinguishing indication information includes the first information; or
and the second method comprises the following steps: the MAC subheader is a MAC subheader for BSR:
The MAC control units having the same characteristic include a fixed-length MAC control unit and a variable-length MAC control unit, and the discrimination indication information includes the first information.
And the third is that: the MAC subheader is a MAC subheader for BSR or a MAC subheader for PHR:
the MAC control units with the same characteristics comprise fixed-length MAC control units and variable-length MAC control units, and the distinguishing indication information comprises the first information and the second information;
And fourthly: the MAC subheader is a MAC subheader for physical layer signaling or a MAC subheader for data volume indication:
the MAC control units having the same characteristic include a fixed-length MAC control unit and a variable-length MAC control unit, and the discrimination indication information includes the second information.
the embodiments of the present invention will be described in detail below with reference to several examples.
Example 1: MAC subheader for buffer status report BSR.
In LTE, there are five buffer status report BSRs, namely, a long BSR, a short BSR, a Truncated BSR (Sidelink BSR), and a Truncated BSR (Truncated Sidelink BSR). The first three are fixed lengths and the last two are variable lengths.
to address the foregoing manner, the embodiment of the present invention provides the following 4 MAC subheader structures:
example 1-1: the all BSRs multiplex one logical channel number LCID 0.
At this time, the length of the I field (i.e., the message type subdivision field) is 3 bits, the format of the MAC subheader is shown in fig. 2, in the figure, the MAC subheader is 1byte, and no bit is reserved because of the 3-bit I field and the 5-bit LCID field. If the LCID extension length is greater than 5 bits, the MAC subheader length needs 2 bytes. The L-field in the figure only appears when indicated as Sidelink BSR or truncatedsidenk BSR.
Wherein different values in the I-field represent different MAC CE types, one is for example table 1. The LCID numbers of all BSR types corresponding to the MAC subheaders are the same value.
TABLE 1 all BSR types multiplex a logical channel number
examples 1 to 2: the long BSR, the short BSR and the truncated BSR are classified into a class, and a logic channel number LCID1 is multiplexed; the Sidelink BSR, the Truncated Sidelink BSR are of a type, multiplexing the logical channel number LCID 2.
at this time, the length of the I field is 2 bits, the format of the MAC subheader is shown in fig. 3 and 4, in the figure, the MAC subheader is 1byte, and since the 2-bit I field and the 5-bit LCID field are adopted, there is 1bit reserved bit. If the LCID extension length is 6 bits, no bit is reserved, and if the LCID extension length is more than 6 bits, the MAC subheader length needs 2 bytes.
Where different values in the I-field represent different MAC CE types, one is for example the following table.
TABLE 2 the BSR types are divided into two categories, each multiplexing a logical channel number
Examples 1 to 3: the long BSR, the short BSR and the truncated BSR are classified into one category; truncated Sidelink BSR, Sidelink BSR are a class. If the two BSRs do not occur simultaneously, a logical channel number LCID3 is multiplexed, but the I fields are identified independently. The format is as shown in fig. 3 and 4. The identification of each field in the MAC subheader of the MAC CE is consistent with table 3, but since two types of MAC CEs do not occur simultaneously, the same logical channel number may be multiplexed, and may also be written as LCID 1-LCID 2.
Examples 1 to 4: all BSRs multiplex a logical channel number LCID0, the fixed length and variable length BSRs are distinguished by the length indication field, the BSR types are further distinguished by the I field, and the format is shown in figure 5.
One example is shown in table 3:
table 3 all BSR types multiplex a logical channel number, and the E field (i.e. the extended indicator field indicating whether the length indicator field exists) distinguishes the fixed and variable length MAC CEs
Example 2: and reporting the MAC subheader of the PHR aiming at the power headroom.
In LTE, there are three types of PHR MAC CEs: PHR, Extended Power Headroom Report, Dual Connectivity Power Headroom Report. Wherein the PHR MAC CE is a fixed length, and both the extended PHR MAC CE and the dual connectivity PHR MAC CE are variable lengths.
all types of PHR MAC CEs multiplex one logical channel number LCID 3.
at this time, the length of the I domain is 1bit, the format of the MAC sub-header is shown in FIG. 6, and in FIG. 6, the MAC sub-header is 1-2 bytes, the length of the LCID domain is 5 bits, the length of the E domain is 1bit, the length of the I domain is 1bit, the length of the R domain is 1bit, and the length of the L domain is 1 byte. If the length of the LCID is extended to 6 bits, no R domain exists (namely reserved bits), and if the LCID is larger than 6 bits, the length of the MAC subheader needs 2-3 bytes. Table 4 shows an example of values of each domain in the MAC subheader corresponding to each PHR type.
Table 4 all PHR types multiplex a logical channel number
Example 3: MAC subheaders activated for component carriers.
The MAC CE that activates/deactivates the component carrier in the CA is an Activation/Deactivation MAC CE (Activation/Deactivation MAC Control Elements), and two types are currently configured for different numbers of component carriers: 1byte activates/deactivates MAC CE, suitable for the situation of maximum 8 member carriers; the 4 bytes activate/deactivate the MAC CE, which is suitable for the case of maximum 32 component carriers. In NR, the number of carriers that can be subject to carrier aggregation (i.e., CA) will be higher, e.g., 64, 128.
All activated/deactivated MAC CEs multiplex one logical channel number LCID 4. The activation/deactivation of the MAC CE is of a fixed length, and an I field is adopted to indicate a specific MAC CE type. The format of the MAC subheader is shown in fig. 7, where the MAC subheader in fig. 7 is 1byte, and there is 1bit reserved bit due to the 2bit I field and the 5bit LCID field. If the LCID extension length is 6 bits, no bit is reserved, and if the LCID extension length is more than 6 bits, the MAC subheader length needs 2 bytes.
Where different values in the I-field represent different MAC CE types, one is for example the following table. Of which 8 byte activated/deactivated MAC CE and 16 byte activated/deactivated MAC CE are not present in LTE and may be present in NR, which is only an example here.
TABLE 5 all BSR types multiplex a logical channel number
Example 4: MAC CE for DRX command.
There are currently two classes of MAC CEs for DRX commands: DRX command MAC CE and long DRX command MAC CE. DRX commands the MAC CE to have only a MAC subheader.
the MAC CE of the DRX command multiplexes one logical channel number LCID 5. The format as shown in FIG. 8 can be adopted, wherein the length of the I field is 1-2 bits. The I field may be 1bit if it is determined that there are only two types of DRX command MAC CEs, and 2bit if a new DRX command MAC CE needs to be introduced.
Example 5: downlink MAC CE for physical layer signaling and data volume indication.
referring to LTE, there are two types of downlink MAC CEs for physical layer signaling and data volume indication: a Recommended bit rate MAC CE (Recommended bit rate MAC Control Element) which is a fixed length, and an Activation/Deactivation CSI-RS resource MAC CE (Activation/Deactivation of CSI-RS resources MAC Control Element; CSI-RS, channel state information reference signal) which is a variable length.
The recommended bit rate MAC CE and the activation/deactivation CSI-RS resource MAC CE multiplex one logical channel number LCID 6. The MAC subheader format may be as shown in fig. 9. And if E-0 indicates that there is no L domain, namely the MAC CE length is fixed, the CSI-RS resource MAC CE is activated/deactivated, and if E-1 indicates that there is an L domain, namely the MAC CE length is variable.
if there is more physical layer signaling and data volume in NR indicating the introduction of downlink MAC CE, the I-domain indication can be further increased.
