Abstract

The present invention discloses an information processing method, user equipment and a base station. The method applied in the user equipment may include: the first user equipment receives first scheduling information sent by the base station; wherein, the first scheduling information indicates that the first Scheduling information for a user equipment to perform at least N uplink data transmissions using unlicensed spectrum; the N uplink data transmissions are uplink transmissions of different redundancy versions of the same data content; the N is an integer not less than 2; according to the The above first scheduling information, determine the different redundancy versions corresponding to the data content of each uplink data transmission; before performing uplink data transmission, detect whether the unlicensed spectrum is idle and form the detection result; based on the indicated performing the uplink data transmission according to the interception result that the unlicensed spectrum is idle.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information processing method, user equipment and a base station. Background technique [0002] In a long term evolution (Long Term Evolution, LTE) communication system, user equipment will use unlicensed spectrum to send uplink data according to the downlink control information sent by the base station. When the uplink data is sent using the unlicensed spectrum, if the uplink data sent by the user equipment using the unlicensed spectrum A is decoded incorrectly, the uplink data needs to be retransmitted using the unlicensed spectrum A. However, the unlicensed spectrum A may be used by user equipment A at time A, but user equipment A's retransmission time B is used by user equipment B. [0003] This will lead to such a problem. At the retransmission time B, the base station does not receive the data sent by user equipment A, and may think that it failed to send the downlink ...
