Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] figure 1 It is a schematic flow diagram of the method of the embodiment of the present invention, such as figure 1 As shown, the scheduling method implemented in this embodiment mainly includes:

[0031] Step 101 , when each scheduling time arrives, determine whether there is a private network voice user with limited transmission power among the users who need to be scheduled currently.

[0032] Considering that the voice users affected by the eMTC UE are usually the voice users at the edge, because these users are at the edge, in order to communicate normally, the transmission power used often reaches the maximum power value, that is, they belong to the power-limited users. For this reason, when each scheduling time arrives in t...

Abstract

The present application discloses a scheduling method and device, including: when each scheduling time arrives, determine whether there is a private network voice user with limited transmission power among the users currently needing scheduling; when there is the private network voice user, First use the narrowband NB reserved resources to allocate resources for the private network voice users; then use the remaining system uplink NB resources after the allocation, and allocate resources to other users to be scheduled at this scheduling time according to the preset resource usage principle , wherein the NB reserved resources belong to a part of system uplink NB resources, and the resource usage principle includes that eMTC users cannot use the NB reserved resources. The present invention can solve the problem of eMTC UE's uplink voice interference to private network clusters, and effectively improve the voice quality.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a scheduling method and device. Background technique [0002] In the private network broadband cluster network, enhanced machine type communication (eMTC) features need to be deployed to carry services with IoT characteristics in various private networks. [0003] The maximum bandwidth supported by eMTC user equipment (UE) is 1.4MHz, which corresponds to a maximum bandwidth of 6RB. The maximum uplink / downlink TBS is 1000, the number of antennas is 1, and the maximum uplink transmit power is 20dBm (optional). [0004] Since the baseband and radio frequency bandwidth of eMTC UE is 1.4MHz, 3GPP defines 6 consecutive PRBs that do not overlap as a narrowband (Narrowband, NB for short), and divides the system bandwidth into several NBs. The scheduling of eMTC UEs is limited by NBs and cannot Cross-NB scheduling. [0005] In order to take into account the coverage depth and c...
