Embodiment two
Embodiment two provides the mode and TBS table of TBS value relevant with particular service in determining table.The present embodiment
It can be based on previous embodiment, it can also be independently of previous embodiment.
It is discussed in detail so that particular service is voice service as an example below.
As previously mentioned, fixed sum data is close in high-rise data package size, i.e. MAC PDU value really for TBS value in TBS table
Cut phase is closed, and therefore, herein for various voice services, most directly, when we can first calculate data transmission, data are corresponding
MAC PDU value, by least one of these values as the value in TBS table.For example the TBS table can be and aim at voice
In the new TBS table of service design (such as a kind of value of table 2 of embodiment) or the TBS table can be in existing TBS
It include the TBS value of voice service on the basis of table, it can by the TBS value of voice service, be added to existing TBS table
In lattice, a more complete TBS table is formed.
In order to calculate voice service data MAC PDU value, need simply to introduce the protocol model of communication system.
The protocol stack model of communication system can be as shown in figure 5, be respectively real-time transport protocol (real-time from top to bottom
Transport protocol, RTP) layer, user datagram (user datagram protocol, UDP) layer, (internet
Protocol, IP) it is layer, Packet Data Convergence Protocol (packet data convergence protocol, PDCP) layer, wireless
Link control (radio link control, RLC) layer, media access control (media access control, MAC) layer and
Physics (physical, PHY) layer.
Optionally, for NR system, between IP layers and PDCP layers, business datum can also be added and adapt to agreement
(service data adaption protocol, SDAP) layer forms 8 layer models.For example, that communication equipment access is LTE
Core net, then without the SDAP layers, the transmission of data, which may not need, considers the packet header SDAP size.The NR's of communication equipment access
Core net then may include the SDAP layers, and the transmission of data at this time may need to consider the packet header SDAP size.
Based on this, for voice service, in high level, that is, it is transmitted to before physics (PHY) layer, MAC PDU can pass through
Formula (9) determines.
MAC PDU=real-time transport protocol (real-time transport protocol, RTP) load (payload)
Size+robustness header compression (robust header compression, RoHC) packet header (header) size+layer 2 (layer2,
L2) header size, formula (9).
Wherein RoHC header size indicates (silence insertion for speech frame and silent insertion
Descriptor, SID) frame value is different, such as distinguishing can be 2 bytes (16 bit), 3 bytes (24 bit), 6 bytes (48
Bit) or other values.L2header size may include the size of MAC/RLC/PDCP header, or also may include
Other additional information bits, other additional information bits can serve to indicate that or handle small variation, such as short caching shape
State reports (short buffer status report, short BSR), power headroom reporting (PHR) (power headroom
Report, PHR) etc..
About voice service, EVS can specifically include the mode for corresponding to different coding mode and code rate individually below: primary

TBS value 1320 is closer to, then can be adjusted to the two values, the TBS for being added to existing table 5.1.3.2-2 for 1324
Value, for original table 5.1.3.2-2, then deletes original TBS value 1328.
Wherein, the calculation for adjusting TBS value can be the average value for taking two considered values, or be also possible to it
Its operation, the application are not construed as limiting this.If calculating resulting number is non-integer, it is further contemplated that round up, or
Person is rounded downwards, to obtain integer value.
