Problems solved by technology

If the soft cache is allocated to the NR system according to the minimum transmission block size and the minimum HARQ RTT, the terminal soft cache cannot meet the requirements of the NR system. If the soft cache is allocated to the NR system according to the maximum transmission block size and the maximum HARQ RTT, the utilization of the terminal soft cache Therefore, the terminal soft cache of NR system can be segmented in a dynamic or semi-static way
However, for the 5G mobile communication system, the terminal can support the dual connection scenarios of LTE and NR, but the prior art does not provide a soft cache management method under the dual connection coexistence of LTE connection and NR connection

Abstract

The invention discloses a soft cache processing method, a terminal and a network device under dual connectivity. The method comprises: acquiring a first reference factor corresponding to a first network standard and a second reference factor corresponding to a second network standard under dual connectivity; The first reference factor and the second reference factor segment corresponding soft buffers for the first network standard and the second network standard, and obtain soft buffer splitting information; and send the soft buffer splitting information to the network device. According to the obtained first reference factor corresponding to the first network standard and the second reference factor corresponding to the second network standard, the terminal of the present invention splits the corresponding soft cache for the first network standard and the second network standard, thereby ensuring The optimized segmentation of the respective soft caches under the dual connection and different network standards can improve the utilization rate of the soft cache under the premise of ensuring data transmission performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a soft buffer processing method under dual connection, a terminal and a network device. Background technique [0002] In the fourth generation (4 th Generation, 4G) mobile communication system, or called long-term evolution (Long TimeEvolution, LTE) system, a transmission time interval (Transmission Time Interval) of scheduling data in a Hybrid Automatic Repeat Request (HARQ) process, TTI) is fixed, the subcarrier spacing is fixed, and the round-trip delay (Round-Trip Time, RTT) of HARQ is fixed, the maximum bandwidth of a component carrier (ComponentCarrier, CC) is 20MHz, and the size of the transport block (Transport Block, TB) is also relatively fixed. In the LTE system, the soft buffers between different HARQ processes are divided in equal proportions and fixed, and one HARQ soft buffer is shared between different component carriers. Among them, the soft ca...
