Data segmentation method, apparatus, and terminal

A data segmentation method, comprising:

• receiving, by a transmitting node, data segmentation indication information sent by a receiving node, and segmenting, by the transmitting node, first-type data according to the data segmentation indication information and an operation parameter of the transmitting node;
• and
• sending, by the transmitting node, second-type data resulted from the segmentation and an actual segmentation manner to the receiving node,
• wherein the data segmentation indication information comprises at least one of:
• a number of the second-type data, a data size of the second-type data, a resource occupied by the second-type data, channel state information used by the second-type data, and a modulation and coding scheme corresponding to the second-type data;
• and
• wherein the data segmentation indication information is determined by the receiving node based on one or more of channel state information, an interference condition, a load condition, service characteristics, and a capability of the receiving node, and when the data segmentation indication information determined by the receiving node based on one or more of channel state information, an interference condition, a load condition, and service characteristics indicates a value X, and the data segmentation indication information determined by the receiving node based on the capability of the receiving node indicates a value N, the data segmentation indication information actually used indicates min(X, N), where min(X, N) is a function for taking the minimum value of the value X and the value N, and N is a fixed configuration for a specific user.

A communication system, comprising a first data segmentation apparatus and a second data segmentation apparatus, wherein:

• the first data segmentation apparatus comprises:
• a first determining unit configured to determine data segmentation indication information corresponding to first-type data;
• and
• a first transmitting unit configured to send the data segmentation indication information to a transmitting node to suggest a segmentation manner used by the transmitting node to segment the first-type data;
• the second data segmentation apparatus comprises:
• a receiving unit configured to receive data segmentation indication information sent by a receiving node, and segment the first-type data according to the data segmentation indication information and an operation parameter of a transmitting node;
• and
• a second transmitting unit configured to send the second-type data resulted from the segmentation and an actual segmentation manner to the receiving node,
• wherein the data segmentation indication information comprises at least one of:
• a number of the second-type data, a data size of the second-type data, a resource occupied by the second-type data, channel state information used by the second-type data, and a modulation and coding scheme corresponding to the second-type data;
• and
• wherein the first determining unit determines the data segmentation indication information based on one or more of channel state information, an interference condition, a load condition, service characteristics, and a capability of the receiving node, and when the data segmentation indication information determined by the first determining unit based on one or more of channel state information, an interference condition, a load condition, and service characteristics indicates a value X, and the data segmentation indication information determined by the first determining unit based on the capability of the receiving node indicates a value N, the data segmentation indication information actually used indicates min(X, N), where min(X, N) is a function for taking the minimum value of the value X and the value N, and N is a fixed configuration for a specific user.
