Description

Data transmission recovery method, terminal and system in LTE network

technical field

The present invention relates to the field of communication technologies, and in particular to a data transmission recovery method, terminal and system in an LTE network.

Background technique

In the Long Term Evolution (LTE for short) network, after the user equipment (UE), that is, the terminal, accesses the network system, if it wants to initiate data transmission, it needs to send a scheduling request (SR) to the base station first, and the terminal can use the uplink control The channel transmission scheduling request requests the base station to allocate uplink shared channel resources. After receiving the scheduling request, the base station allocates uplink shared channel resources to the terminal for uplink data transmission when there is uplink data to be sent.

Before allocating resources to the terminal for uplink data transmission, the base station will send a radio allocation message (RRC) to the terminal. The radio allocation message carries the scheduling request resource configuration information and the measurement gap (GAP) resource configuration information, which is used to determine the scheduling request. The sending location of the resource and the location of the measurement gap resource.

The scheduling request resource configuration information mainly includes the scheduling request configuration index I _SR , the scheduling request sending cycle and the subframe position are determined by the configuration index I _SR , and the specific calculation formula is as follows:

(10×SFN+subframe-N _OFFSET,SR ) modSR _Periodicity =0

Among them, SFN is the system frame number sent by the scheduling request, subframe is the subframe number sent by the scheduling request, N _{OFFSET, SR} is the subframe offset of the scheduling request, and SR _Periodicity is the sending period of the scheduling request, which can be determined by the configuration index I in Table 1 below _SR got.

Table 1

Measurement gap resources are resources defined in the LTE network to support inter-frequency/inter-standard synchronization and measurement. Once the terminal enters the measurement gap resource time, it will not allow any uplink and downlink channel transmission. There are two periodic modes for measurement gap resources, the periods are 40ms and 80ms respectively, and the measurement gap resource configuration information sent by the base station determines which mode to use. The measurement gap resource duration is fixed at 6ms regardless of the periodic mode. The measurement gap resource configuration information mainly includes the measurement gap resource period, the measurement gap resource subframe offset gapoffset, etc. The starting position of the measurement gap resource is based on the measurement gap resource period and the measurement gap resource subframe offset in the measurement gap resource configuration information. The gapoffset is calculated, and the specific calculation formula is as follows:

SFN mod T = FLOOR(gapoffset/10);

subframe = gapoffset mod 10;

Wherein, T is one tenth of the period of the measurement gap resource, SFN is the starting system frame number of the measurement gap resource, and subframe is the starting subframe number of the measurement gap resource. The SFN and subframe jointly determine the starting position of the measurement gap resource.

There will inevitably be conflicts between the scheduling request resources sent by the base station to the terminal and the measurement gap resources. For example, when the measurement gap resource period is 80ms, the measurement gap resource subframe offset gapoffset=0, and the scheduling request configuration index I _SR =78, the system frame number SFN mod 8 =0 of the measurement gap resource is calculated according to the above formula, the starting subframe of the measurement gap resource is subframe 0, and since the duration of the measurement gap resource is fixed at 6ms regardless of the periodic mode, Then the measurement gap resource occupies 6 subframes of subframe 0 to subframe 5 in total.

By comparing Table 1, the sending period of the scheduling request is also 80ms, and then according to the calculation formula, the system frame number SFN mod 8 = 0 for the scheduling request, and the subframe offset of the scheduling request N _{OFFSET, SR} = I _SR -75 = 3 , then the subframe for sending the scheduling request is the third subframe, that is, subframe 3.

It can be seen from the above that the system frame number of the scheduling request is exactly the same as the system frame number of the measurement gap resource (both are 0), and the sending subframe of the scheduling request is subframe 3, which falls in the subframe 0~subframe occupied by the measurement gap resource. Within the range of frame 5, the sending position of the scheduling request resource coincides with the position of the measurement gap resource.

Once the terminal enters the measurement gap resource time, it will not allow any uplink and downlink channel transmission, and because the sending position of the scheduling request resource coincides with the position of the measurement gap resource, the terminal cannot use the uplink control channel to send the scheduling request, and it cannot use the uplink sharing The channel performs any data transmission, and thus cannot receive data at the carrier frequency where the serving cell is located, resulting in interruption of data transmission.
