Methods and apparatuses for transmitting and receiving control signaling, and method for determining information

A method for transmitting control signaling, comprising:

• transmitting a first signal and a first physical dynamical control signaling scheduling the first signal, wherein the first signal includes a first aperiodic downlink measurement reference signal, a first time interval between the first signal and the first physical dynamical control signaling being less than a predetermined threshold X1;
• and
• transmitting a second signal and a second physical dynamical control signaling scheduling the second signal,
• wherein the second signal includes a second aperiodic downlink measurement reference signal, a second time interval between the second signal and the second physical dynamical control signaling being greater than or equal to a predetermined threshold X2, and
• wherein the first signal and the second signal are transmitted at a same time-domain symbol, a QCL parameter of the first signal being based on a QCL parameter of the second signal.

An apparatus for receiving control signaling and for determining information, the apparatus comprising a processor, the processor being configured to:

• receive a first signal and a first physical dynamical control signaling scheduling the first signal, wherein the first signal includes a first aperiodic downlink measurement reference signal, a first time interval between the first signal and the first physical dynamical control signaling being less than a predetermined threshold X1;
• receive a second signal and a second physical dynamical control signaling scheduling the second signal, wherein the second signal includes a second aperiodic downlink measurement reference signal, a second time interval between the second signal and the second physical dynamical control signaling being greater than or equal to a predetermined threshold X2, and
• wherein the first signal and the second signal are received at a same time-domain symbol;
• and
• determining a quasi co-location (QCL) parameter of the first signal based on a QCL parameter of the second signal.
