Information processing method and apparatus

An information processing method, applied to a multiple-input multiple-output (MIMO) communications system, wherein a plurality of data demodulation reference signal ports are allocated to a UE, and the method comprises:

• obtaining, in a scheduled time-frequency resource, information about whether the plurality of data demodulation reference signal ports allocated to the UE meet a particular port relationship;
• and
• for at least two data demodulation reference signal ports, of the plurality of data demodulation reference signal ports, that meet the particular port relationship, performing, by the UE, channel estimation, frequency offset estimation, or demodulation by using same parameters, and for data demodulation reference signal ports of the plurality of data demodulation reference signal ports that do not meet the port relationship, separately obtaining, by the UE, parameters and performing, by the UE, channel estimation, frequency offset estimation, or demodulation by using different parameters,
• wherein meeting the particular port relationship indicates that the at least two data demodulation reference signal ports of the plurality of data demodulation reference ports are quasi co-located.

An information processing apparatus, applied to a multiple-input multiple-output (MIMO) communications system, wherein a plurality of data demodulation reference signal ports are allocated to a user equipment (UE) in the MIMO communication system, and the apparatus comprises:

• a processor:
• and
• a memory storing instructions that when executed by the processor, configure the processor to:
• obtain, in a scheduled time-frequency resource, information about whether the plurality of data demodulation reference signal ports allocated to the UE meet a particular port relationship, wherein meeting the particular port relationship means that signals sent by using any ports experience same or similar large-scale properties;
• and
• send an indication of the information about whether the particular port relationship is met, so that for at least two data demodulation reference signal ports, of the plurality of data demodulation reference signal ports, that meet the particular port relationship, the UE performs channel estimation, frequency offset estimation, or demodulation by using same parameters;
• and
• for data demodulation reference signal ports that do not meet the particular port relationship, separately obtain, by the UE, different parameters, and separately performing channel estimation, frequency offset estimation, or demodulation processes by using the different parameters,
• wherein meeting the particular port relationship indicates that the at least two data demodulation reference signal ports of the plurality of data demodulation reference ports are quasi co-located.
