Problems solved by technology

[0021] After the above analysis, it can be found that there is a problem in the prior art: according to the existing buffer division method, for the high-end UE (type 4, 5), the TDD terminal also divides the buffer equally according to 8 processes, resulting in , the number of processes corresponding to the partial frame structure ratio configuration (9, 10, 12, 15 processes) can not be stored in the case of an error exceeding 8, and the buffer size of each process in equal parts is larger than that of each process The actual amount of data that needs to be stored after a decoding error causes a waste of buffer memory

Embodiment Construction

[0077] The embodiment of the present invention proposes: obtaining the product of the maximum number of streams used for PDSCH transmission received by the UE and the maximum number of HARQ processes supported by the downlink; obtaining the smaller value of the product and a preset threshold; according to the smaller value, etc. According to the total capacity of the terminal buffer, obtain the capacity of the buffer allocated for each process in the terminal.

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. ...

Abstract

The embodiment of the invention discloses a method and a device for partitioning a terminal buffer. The method comprises the following steps of: acquiring product of the maximum flow number which is used by physical downlink shared channel (PDSCH) transmission and received by user equipment (UE) and the maximum hybrid automatic retransmission request (HARQ) process number supported by downlink; acquiring a smaller value of the product and a preset threshold value; and equally partitioning the total capacity of the terminal buffer according to the smaller value, and acquiring the capacity of buffer partitioned for each process in the terminal. Through the method and the device, the condition of high process number of time division duplex (TDD) is effectively supported, the phenomenon that storage cannot be performed after the high process number of the TDD has error is avoided and waste of the buffer is avoided, and the method and the device have universal applicability.

Description

technical field [0001] The invention relates to the communication field, in particular to a terminal buffer division method and device. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, for a TDD (Time Division Duplex, time division duplex) terminal and an FDD (Frequency Division Duplex, frequency division duplex) terminal, the buffer size of the terminal design is the same, but in practical applications The number of processes stored in the cache may vary. In the existing relationship between the number of processes corresponding to FDD and TDD, in FDD mode, the maximum number of processes supported by the downlink is 8; in TDD mode, the maximum number of processes supported by the downlink is related to the configuration of the frame structure ratio of TDD, and the specific correspondence The relationship is shown in Table 1: [0003] Table 1. The relationship between the maximum number of processes supported by the downlink and ...
