Abstract
Provided are a method and apparatus for obtaining information and sending information, terminal, base station and storage medium. The method for obtaining information includes: performing, by a terminal, a blind detection on transmission indication information according to a case where a size of an antenna port field in the transmission indication information has a maximum value; or performing, by the terminal, the blind detection on the transmission indication information according to a larger size between a size of the antenna port field corresponding to the mapping type one and a size of the antenna port field corresponding to the mapping type two.

A method for obtaining information, comprising:
- performing, by a terminal, a blind detection on a bandwidth part resource in one of following two manners to obtain transmission indication information sent by a base station:
- in a manner one:
- performing, by the terminal, the blind detection on the transmission indication information according to a case where a size of an antenna port field in the transmission indication information has a maximum value;
- or
- in a manner two:
- inquiring, by the terminal, a demodulation reference signal (DMRS) configuration parameter corresponding to a mapping type one and a DMRS configuration parameter corresponding to a mapping type two respectively;
- in a case where a parameter related to an antenna port field in the DMRS configuration parameter corresponding to the mapping type one is the same as a parameter related to an antenna port field in the DMRS configuration parameter corresponding to the mapping type two, performing, by the terminal, the blind detection on the transmission indication information according to a size of the antenna port field corresponding to one of the mapping type one or the mapping type two;
- in a case where the parameter related to the antenna port field in the DMRS configuration parameter corresponding to the mapping type one is different from the parameter related to the antenna port field in the DMRS configuration parameter corresponding to the mapping type two, performing, by the terminal, the blind detection on the transmission indication information according to a larger size between a size of the antenna port field corresponding to the mapping type one and a size of the antenna port field corresponding to the mapping type two.
A terminal, comprising a processor, a memory, a communication device, and a communication bus;
- wherein
- the communication bus is configured to implement a connection communication between the processor and the memory and a connection communication between the processor and the communication device;
- and
- the processor is configured to execute at least one program stored in the memory to implement:
- performing a blind detection on a bandwidth part resource in one of following two manners to obtain transmission indication information sent by a base station:
- in a manner one:
- performing the blind detection on the transmission indication information according to a case where a size of an antenna port field in the transmission indication information has a maximum value;
- or
- in a manner two:
- inquiring a demodulation reference signal (DMRS) configuration parameter corresponding to a mapping type one and a DMRS configuration parameter corresponding to a mapping type two respectively;
- in a case where a parameter related to an antenna port field in the DMRS configuration parameter corresponding to the mapping type one is the same as a parameter related to an antenna port field in the DMRS configuration parameter corresponding to the mapping type two, performing the blind detection on the transmission indication information according to a size of the antenna port field corresponding to one of the mapping type one or the mapping type two;
- in a case where the parameter related to the antenna port field in the DMRS configuration parameter corresponding to the mapping type one is different from the parameter related to the antenna port field in the DMRS configuration parameter corresponding to the mapping type two, performing the blind detection on the transmission indication information according to a larger size between a size of the antenna port field corresponding to the mapping type one and a size of the antenna port field corresponding to the mapping type two.
