Problems solved by technology

[0004] In this way, the following problems will arise: some terminals with a relatively small amount of data to be transmitted in the empty packet use more RBs under a certain MCS level, resulting in a mismatch between the TBsize and the amount of data to be transmitted. Padding, which increases the encoding rate and retransmission rate, reduces the reliability of transmission

Embodiment 1

[0021] figure 1 A schematic diagram of the implementation flow of the data processing method in Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes the following steps:

[0022] Step 101: Acquire the amount of data to be transmitted of the data to be transmitted;

[0023] When the base station side schedules a single space division terminal, the data packets to be transmitted from the core network include the data to be transmitted, and the data packets to be transmitted pass through the Packet Data Convergence Protocol (PDCP) layer and the radio link control layer protocol. After processing by the Radio Link Control (RLC) layer, the media access control sublayer protocol (Media Access Control, MAC) layer reports the amount of data to be transmitted. The MAC layer determines the amount of data to be transmitted according to the resource allocation strategy of space division multiplexing The MCS and RB corresponding to the data.

[0024]...

Embodiment 2

[0057] In this embodiment, the data processing method provided by the embodiment of the present invention is described by taking the data to be transmitted as the downlink data to be transmitted as an example.

[0058] When the base station side schedules a single space division terminal, the data packets to be transmitted from the core network are processed by the PDCP layer and the RLC layer and then reported to the MAC layer for an amount of data to be transmitted, which is determined by the MAC layer according to the space division resource allocation strategy. MCS and RB. After the MCS and RB are determined, the MCS is adjusted by using the data processing method provided in the embodiment of the present invention, such as figure 2 shown, including:

[0059] Step 201: Determine the transmission type of the terminal according to the number of streams, new transmission / retransmission, and transmission mode;

[0060] The number of streams, new transmission / retransmission ...

Embodiment 3

[0081] Based on the foregoing embodiments, the embodiments of the present invention provide a data processing apparatus, such as image 3 As shown, the data processing apparatus 30 includes: an acquisition module 31, a first determination module 32 and an adjustment module 33, wherein,

[0082] an acquisition module 31, configured to acquire the amount of data to be transmitted of the data to be transmitted;

[0083] a first determining module 32, configured to determine the transmission type of the data to be transmitted;

[0084] The adjustment module 33 is configured to adjust the modulation and coding strategy MCS of the to-be-transmitted data according to the transmission type and the to-be-transmitted data amount to obtain an adjusted MCS.

[0085] In one embodiment, the adjustment module 33 is further configured to downgrade the MCS of the data to be transmitted to obtain a first MCS; compare the size of the first transmission block corresponding to the first MCS with ...

Description

technical field [0001] The embodiments of the present invention relate to, but are not limited to, the field of communications technologies, and in particular, relate to a data processing method, a device, and a computer-readable storage medium. Background technique [0002] With the continuous development of the fourth generation (4G) mobile communication system, Massive MIMO (Massive MIMO) technology will become an important technology for improving network capacity. In the Frequency Division Duplexing (FDD) system, the departure angle (DOA) of the uplink and downlink channels is reciprocal, and the Massive MIMO technology divides the cell into multiple prefabricated beam coverages according to the DOA range, and According to a certain strategy, an activated beam is selected for the terminal, and the base station sends data to the terminal through the activated beam. Terminals with disjoint activation beams can space-division multiplex the same time-frequency resources to...
