Embodiment Construction

[0030] In order to solve the disadvantages of the traditional technical solutions, the present invention further illustrates a wireless data receiving method according to the present invention through the following specific embodiments. The specific embodiments are described in detail below, but are not intended to limit the present invention.

[0031] The core idea of ​​the present invention is: the terminal calculates the link quality at this time through reference signals or other methods, and determines the link quality according to the calculated link quality and control information (code rate, modulation mode, original data packet length, etc.) The code rate at which the received data packet can be decoded correctly, and then further determine the data length Mbit that needs to be received according to the code rate. The terminal selects the part of the received data Mbit from the sent data according to the above calculation, and compares the received data Perform channel es...

Abstract

The invention discloses a method for receiving a wireless data packet, which comprises the following steps: A: a receiving terminal obtains the corresponding code rate V according to the current link quality condition and the original data packet length L; B: the data length M in the same order, which needs to be received is estimated according to the code rate V and the original data packet length L; and C: after receiving the data to be received, which have the length of at least M, the receiving terminal decodes the data so as to obtain the original data packet. The terminal with good linkquality can select data volume according to the acceptable code rate of the terminal to receive and decode under the condition of not influencing the receiving of the terminal with poor link quality and reduce the received redundant data volume, thereby realizing the electric energy saving of the terminal with good link quality.

Description

Technical field [0001] The invention relates to a method for receiving wireless data, in particular to a method for receiving data packets in MBMS (Multimedia Broadcast Multicast) service. Background technique [0002] The transmission medium of wireless communication is the wireless channel. More precisely, the wireless channel is the propagation path between the base station antenna and the user antenna. The antenna induces current to generate electromagnetic oscillation and radiate electromagnetic waves. These electromagnetic waves propagate in free space or air, and are finally induced by the receiving antenna to generate induced current. The propagation path of electromagnetic waves may include direct propagation and indirect propagation. The existence of multiple propagation paths causes changes in the characteristics of wireless signals. [0003] The fading characteristic of the wireless channel depends on the radio wave propagation environment. Different environments have...
