Embodiment 1

[0018] refer to figure 1 , shows a flow chart of steps of a method for grouping data according to Embodiment 1 of the present invention.

[0019] The data package method of the present embodiment comprises the following steps:

[0020] Step S102: determining the RB of the data to be sent is organizing the data to be sent into UL grant resources according to the SDU length vector corresponding to the RB.

[0021] Wherein, the elements in the SDU length vector are respectively used to identify the segment length of each SDU of the RB.

[0022] According to the SDU length vector corresponding to the RB, the data to be sent by the RB is organized into UL grant resources. Except for the last SDU, the actual data length in other SDUs is the same as the SDU segment length, that is, as long as the SDU segment If the length is determined, the actual data length in the corresponding SDU is determined; the actual data length in the last SDU may be less than or equal to the SDU segment ...

Embodiment 2

[0037] refer to figure 2 , shows a flow chart of steps of a method for grouping data according to Embodiment 2 of the present invention.

[0038] The data package method of the present embodiment comprises the following steps:

[0039] Step S202: the scheduler allocates UL grant resources for RBs with Bj>0.

[0040] In this embodiment, the technical solution of the present invention is described in detail by taking the MAC layer scheduler as an example for execution.

[0041] The resource allocation scheme in this embodiment is based on the basic framework of two rounds of scheduling. The first round of scheduling is aimed at the PBR result Bj. For RBs with Bj>0, the ULgrant resources are allocated according to the priority order of the RBs according to the Bj result and the SDU length vector. to each RB. If all channels are satisfied before the ULgrant resources are exhausted, the second round of scheduling can be entered. The second round of scheduling will allocate the...

Embodiment 3

[0072] refer to image 3 , shows a flow chart of steps of a method for grouping data according to Embodiment 3 of the present invention.

[0073] This embodiment is still based on the basic framework of two-round scheduling, and the data grouping method of this embodiment is described from the aspects of two-round scheduling and BUFFER zero copy.

[0074] The data package method of the present embodiment comprises the following steps:

[0075] Step S302: the MAC scheduler performs a first round of scheduling on all RBs with Bj greater than 0.

[0076] This step is executed when the UL grant authorization notification arrives at the UE. For all RBs with Bj greater than 0, UL grant resources are allocated in the order of priority (if the same priority is in order of ID). The ULgrant authorization length Grant obtained by each RB Step1 It is: in the SDU vector, the integer value is rounded up from Bj, and the remaining ULgrant is Ul rem The minimum value in . At the same tim...

Abstract

The invention provides a data set package method and device. The data set package method comprises the steps that the fact that the RB of data to be transmitted organizes the data to be transmitted to uplink authorization resources according to an SDU length vector corresponding to the RB is determined; the data to be transmitted organized to the uplink authorization resources are subjected to MAC SDU set package first, then the difference between the practical head length and the reserved head length of the MAC PDU is determined according to the MAC SDU set package results; or the length of RLC PDU padded in the last MAC SDU is determined, then the data to be transmitted organized to the uplink authorization resources are subjected to MAC SDU set package; according to the difference between the practical head length and the reserved head length of the MAC PDU or the length of the RLC PDU, and MAC PDU set package is carried out in a buffer zone shared by the MAC layer and the physical layer. According to the data set package method and device, address space waste is avoided, and the MAC PDU set package speed and efficiency are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a MAC (Medium Access Control, medium access control) PDU (Packet Data Unit, packet data unit) grouping method and device. Background technique [0002] In the LTE (Long Time Evolution, long-term evolution) system, a variety of terminal data services show their own unique performance requirements, such as the most typical web pages requiring low response time, FTP (File Transfer Protocol, file transfer protocol) services require data The correctness of the audio and video services, as well as the guaranteed rate requirements. The allocation and competition of these different service data for radio resources will be concentrated in the "multi-RB (Radio Bearer, radio bearer) scheduler" of the MAC (Medium Access Control, medium access control) layer in the LTE system. Because the MAC layer can be understood as the interface between the physical layer and the service l...
