Radio frequency interface transmitting device and method, radio frequency interface receiving device and method, and chip, base station, and terminal

A transmitting method for an RF interface, comprising:

• serially interleaving data of a plurality of data channels based on a current interleaving pattern to form interleaved data of one or more periods, wherein the data of each of the data channels comprises a plurality of unit data blocks, the interleaving pattern indicates a respective number of unit data blocks of each of the data channels comprised in the interleaved data of one period and an arrangement order of the unit data blocks of the plurality of data channels within one period, and the data of the plurality of data channels is serially interleaved based on the same interleaving pattern in the one or more periods, wherein the plurality of data channels correspond to a plurality of services, respectively;
• determining a delay adjustment amount of each of the data channels corresponding to the current interleaving pattern, wherein in a case where a position of a unit data block of one data channel among the plurality of data channels in the current interleaving pattern is shifted by m unit data blocks along a first direction relative to a position of the unit data block of the one data channel in a previous interleaving pattern, a historical delay adjustment amount of the one data channel corresponding to the previous interleaving pattern is shifted by m unit data blocks along a direction opposite to the first direction and then determined as the delay adjustment amount of the one data channel corresponding to the current interleaving pattern, wherein m is an integer greater than or equal to 1;
• forming a service frame based on the interleaved data, wherein the interleaved data is filled into a payload area of the service frame as payload data;
• forming a management frame, wherein the management frame comprises information of the delay adjustment amount of each of the data channels corresponding to the current interleaving pattern;
• and
• sending the service frame or the management frame.

A receiving method for an RF interface, comprising:

• deframing input data according to a service frame structure or a management frame structure to obtain a service frame or a management frame;
• in a case where the service frame is obtained by deframing the input data, deinterleaving payload data of the service frame based on an interleaving pattern to obtain data of a plurality of data channels, wherein the payload data comprises interleaved data of one or more periods, the data of each of the data channels comprises a plurality of unit data blocks, the interleaving pattern indicates a respective number of unit data blocks of each of the data channels comprised in the interleaved data of one period and an arrangement order of the unit data blocks of the plurality of data channels within one period, and the data of the plurality of data channels is serially interleaved based on the same interleaving pattern in the one or more periods, wherein the plurality of data channels correspond to a plurality of services, respectively;
• in a case where the management frame is obtained by deframing the input data, obtaining the interleaving pattern and a delay adjustment amount of each of the data channels corresponding to the interleaving pattern based on the management frame;
• and
• according to respective delay adjustment amounts of the plurality of data channels, delaying the data of each of the data channels by a time corresponding to a respective delay adjustment amount and then outputting the data of the data channel.
