Embodiment 1
[0051] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, figure 1 It is a hardware structure block diagram of a mobile terminal of a data sending method in an embodiment of the present invention. Such as figure 1 As shown, the mobile terminal 10 may include one or more (only one is shown in the figure) processor 102 (the processor 102 may include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), for A memory 104 for storing data, and a transmission device 106 for communication functions. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, the mobile terminal 10 may also include a ratio figure 1more or ...
Embodiment 2
[0099] Figure 9 A schematic diagram of the RLC header, the MAC header and the MAC CE behind the transport block provided for the embodiment of the present invention, as shown in Figure 9 As shown, the header information of the protocol data unit RLC PDU of the second user entity, the MAC subheader and the MAC CE of the third user plane entity are all located behind the transport block. The data is put into the physical layer, and the RLC header and the MAC sub-header are calculated in parallel when the data is sent to the physical layer, which can speed up the scheduling process and reduce the scheduling transmission delay. details as follows:
[0100] There is third length indication information L in each third user plane entity MAC subheader, and the third length indication information is used to indicate the characters between the third length indication information and the corresponding second user plane entity service data unit SDU Section number.
[0101] If the sub...
Embodiment 3
[0117] Figure 10 An illustration of no FI indication in the RLC header provided for the embodiment of the present invention Figure 1 ,Such as Figure 10 As shown, this preferred embodiment 3 is similar to the above preferred embodiment 1, except that there is no FI indication in the header information of the second user plane entity protocol data unit. details as follows:
[0118] There is third length indication information L in each third user plane entity MAC subheader, and the third length indication information is used to indicate the bytes between the third length indication information and the corresponding second user plane entity protocol data unit PDU number.
[0119] If the subheader of the third user plane entity corresponds to the control unit of the third user plane entity, the third length indication information in the third user plane entity subheader is used to indicate that the third length indication information is related to the next third user plane e...
