Claim of US Patent No. 11,032,834

8. A device for information transmission, comprising: a processor, a memory and a transceiver, the memory is configured to store program instructions, when the program instruction stored in the memory are executed by the processor, the processor is configured to:acquire a first signal and second signal, the first signal being a reference signal and the second signal being a control signal; and
control the transceiver to transmit the first signal via a first symbol, with a first subcarrier spacing, of a first time-frequency region and transmit the second signal via a second symbol, with a second subcarrier spacing, of the first time-frequency region, wherein
the first subcarrier spacing is different from the second subcarrier spacing, and a size of the first time-frequency region is a size of a subframe;
the processor is further configured to acquire a ninth signal, the ninth signal being a control signal; and
the processor is further configured to:
control the transceiver to transmit the ninth signal via the first symbol, with the first subcarrier spacing, of the first time-frequency region, wherein the ninth signal and the first signal are arranged alternately on the frequency domain;
wherein the processor is further configured to acquire a third signal and a fourth signal, the third signal being a reference signal and the fourth signal being a data signal or a control signal; and
the processor is further configured to:
control the transceiver to transmit the first signal via the first symbol, with the first subcarrier spacing, of the first time-frequency region over a first cell,
control the transceiver to transmit the second signal via the second symbol, with the second subcarrier spacing, of the first time-frequency region over the first cell,
control the transceiver to transmit the third signal via a third symbol, with the first subcarrier spacing, of a second time-frequency region over a second cell, and
control the transceiver to transmit the fourth signal via a fourth symbol, with a third subcarrier spacing, of the second time-frequency domain over the second cell,
wherein the second subcarrier spacing is different from the third subcarrier spacing, and the first cell is different from the second cell;
the first time-frequency region and the second time-frequency region have a same time domain, have a same frequency domain, or have adjacent frequency domains; and a size of the second time-frequency region is the size of the subframe.
