Below the transmission method to the TSN in the embodiment of the present invention carries out detailed, concrete description as an example of up multi-carrier HSUPA example.Wherein, MAC PDU data block is MAC-i PDU, and MAC PDU sub-block is MAC-is PDU, keeps the length and location in TSN territory in MAC-is PDU constant, and will exceed the bit of original length after the TSN expansion, namely the TSN extended bit is combined into whole byte TSN extension field and is carried at MAC-i PDU.
As shown in Figure 5, the transmission method flow chart for a kind of TSN in the embodiment of the present invention three comprises the following steps:
Particularly, in MAC-i PDU, the length of LCH ID is 4bits, the length of L position is 11bits, the length of F position is 1bit, the length of SS position is 2bits, and the length of TSN is 6bits, and the length of MAC-is SDU is whole byte, therefore, MAC-is PDU is whole byte, and MAC-i Header is also whole byte, when a plurality of MAC-is PDU are multiplexed in a MAC-i PDU, MAC-i PDU is also whole byte, the structure of this byte-aligned is conducive to reduce expense in realization, for example, and the processing expenditure when carrying out the bit displacement.Therefore, the TSN extended bit also needs to be combined into the TSN extension field of whole byte, to be carried at the MAC-i PDU of whole byte.
Wherein, UE determines that the mode of the length of TSN extended bit comprises following two kinds:
A. adopt the length of fixing TSN extended bit
Can determine whether TSN expands by predefine mode or high-level signaling, and when TSN expands, use fixedly extension length as the length of described TSN extended bit.Wherein, the predefine mode can be and multi-carrier HSUPA binding, i.e. binding TSN expansion in multi-carrier HSUPA, and use fixedly extension length as the length of TSN extended bit; When being configured by high-level signaling, whether high level can only indicate TSN can expand, and then UE and network are all known and all can be known TSN is fixedly expanded to the N bit.
B. configure the length of TSN extended bit by high-level signaling
The length of the TSN that UE uses in multi-carrier HSUPA configures by high-level signaling, and high-level signaling can configure the length of one or more TSN extended bits.Wherein, high-level signaling can be the RRC message of RNC notice UE, and/or the NBAP message of RNC notice NodeB, and the length that high-level signaling can configure TSN is N, M bit, as N=6bits, M=9bits.Because the desired number of retransmissions of the traffic performance of different UEs is different, the factors such as the carrier number that network can be supported according to UE, traffic performance be the length that different UE configures different TSN extended bits neatly.
UE determines that the mode of the length of TSN extension field comprises following two kinds:
A. by calculating the length of TSN extension field
UE is according to the length of each TSN extended bit, and the number that comprises TSN in MAC-i PDU calculates the byte number of TSN extension field.Particularly, suppose TSN is fixedly expanded to the M bit, can by the number of LCH corresponding to the data in the judgement of the LCH ID in MAC-i Header MAC-i PDU, suppose to include Num in MAC-i PDU
LCHThe data of individual LCH (being the number of MAC-isPDU or TSN), in existing protocol, the length of TSN is 6bits, the length number of each TSN extended bit is (M-6) bits, can be from the higher bit position intercepting of the TSN after expansion, and also can be from low bit intercepting.
UE is combined into whole byte with a plurality of TSN extended bits, the bit that exceeds original length after soon TSN expansion cascades up and is combined into whole byte, UE with all TSN extended bit cascades after shared byte number round on immediate integer, for example calculate the byte number of TSN extension field by following formula:
For example, if TSN fixedly expands to the M=8 bit, include Num in a MAC-i PDU
LCH=4, Oct
ext=1 byte, the extended bit of TSN can form 1 byte; If the M=9 bit, Num
LCH=5, Oct
ext=2 bytes, the extended bit total length of all TSN reaches 15bits, can form 2 bytes.
B. configure the byte number of TSN extension field by high-level signaling
High-level signaling directly configures all TSN extended bits needed total bytes that combines, the byte number of TSN extension field), wherein, high-level signaling can be the RRC message of RNC notice UE, and/or the NBAP message of RNC notice NodeB.For example, high-level signaling configuration TSN extension field is the N byte, fills out in this N byte after all TSN extended bit cascades, and Padding can be filled in remaining space.
UE is combined into whole byte with the TSN extended bit, refers to that UE carries out cascade, i.e. TSN with each TSN extended bit in the TSN extension field
k+1The N bits of expansion is TSN and then
kThe N bits of expansion can also can hang down bit from beginning during cascade from the higher bit position of byte, the order of the TSN extended bit cascade MAC-is PDU corresponding with each LCH is at the sequence consensus of MAC-i PDU cascade, and perhaps order fully on the contrary.
Wherein, the carrying mode of TSN extension field in MAC-i PDU comprises following several:
1, carry the TSN extension field in MAC-i Header;
This mode can be further divided into again:
1a) the TSN extension field is attached to all MAC-i Header front, as shown in Figure 6.

Wherein, mode 1a, 1b and 1c all can adopt the mode of high-level signaling to configure TSN extension field byte number, and mode 1c can also adopt the mode of calculating to configure TSN extension field byte number.
2, carry the TSN extension field in MAC-i PDU load;
This mode can be further divided into again:
2a) the TSN extension field is included in certain MAC-is PDU
kIn, as shown in Figure 9; Perhaps be attached to MAC-is PDU
