Embodiment 1
[0048] In order to solve the technical problems existing in the prior art, this embodiment provides a method for group operation of logical channels under the LTE standard, such as figure 1 As shown, the method includes:
[0049] S101: Allocate data space for the logical channels in the first array in sequence, so that the logical channels in the first array complete the group operation;
[0050] S102: Allocate data space for the logical channels in the second array in sequence, so that the logical channels in the second array complete the group operation;
[0051] In the above steps S101 to S102, the size of the data space is the sum of the sizes of all data on the logical channel corresponding to the data space.
[0052] In this embodiment, the logical channels are divided into two groups according to the set conditions, and then group operations are performed on the logical channels included in each group, so that only one group operation is performed on the same logical c...
Embodiment 2
[0084] This embodiment and Embodiment 1 belong to the same inventive concept. This embodiment provides an apparatus for allocating resources of logical channels under the LTE standard, such as figure 2 As shown, the device includes:
[0085] The first group operation unit 201 is configured to sequentially allocate data space for the logical channels in the first array, so that the logical channels in the first array complete group operations;
[0086] Specifically, the first group of operating units 201 further includes:
[0087] The first reading module is used to read the logical channels from the first array in the order of the priority of the logical channels from high to low; reading the logical channels in the order of the priority of the logical channels from high to low can be Logical channels with higher priority are processed first.
[0088] The first allocation module is configured to allocate data space for the logical channel; at this time, the size of the dat...
Embodiment 3
[0118] This embodiment describes the present invention in detail through an actual scene.
[0119] Before performing the logic channel priority processing process, the B value needs to be updated first. The process of updating B value is as follows: image 3 As shown, the B value of each logical channel is set to 0 when the logical channel is initially established, and an increase operation is performed on each transmission time interval (TransmissionTimeInterval, TTI), including:
[0120] S301: Determine whether the B values of all logical channels have been updated, if so, end the process, otherwise continue to the next step;
[0121] S302: Read the next logical channel that needs to update the B value, and set the number of the logical channel to j;
[0122] S303: B j Increase PBR j size of PBR j is the priority bit rate of the j-th logical channel, B j Amount to increase on each TTI. PBR j Provisioning from the network to the user equipment;
[0123] S304: Judgm...
