Pilot frequency transmission method for uplink shared channel, and related device

A method for transmitting pilots of an uplink shared channel, the method comprising:

• determining, by a base station, transmit power at which a UE transmits data carried in the uplink shared channel;
• and
• determining, by the base station, transmit power at which the UE transmits the pilots of the uplink shared channel according to the transmit power at which the UE transmits the data carried in the uplink shared channel, and a pilot power boosting factor, wherein the pilot power boosting factor represents how many times transmit power of a pilot in a resource element of the uplink shared channel is over transmit power of data in a resource element of the uplink shared channel, the pilot power boosting factor is more than or equal to 1, and the pilots are transmitted in a symbol occupied by the pilots with a comb-like pattern,
• wherein the pilot power boosting factor is:
• configured by a network side to the UE via higher-layer signaling;
• or
• predefined between the network side and the UE in a protocol;
• or
• determined according to a frequency mapping interval or a frequency mapping density at which the pilots are transmitted with the comb-like pattern, or the number of UEs for which multiplex pilots are in the same symbol with the comb-like pattern.

A UE, comprising a memory and at least one processor, wherein the memory is configured to store readable program codes, and the at least one processor is configured to execute the readable program codes to:

• determine transmit power of data carried in an uplink shared channel;
• determine transmit power of pilots of the uplink shared channel according to the transmit power of the data carried in the uplink shared channel, and a pilot power boosting factor, wherein the pilot power boosting factor represents how many times transmit power of a pilot in a resource element of the uplink shared channel is over transmit power of data in a resource element of the uplink shared channel, the pilot power boosting factor is more than or equal to 1, and the pilots are transmitted in a symbol occupied by the pilots with a comb-like pattern;
• and
• transmit the pilots of the uplink shared channel at the transmit power of the pilots;
• wherein the pilot power boosting factor is configured by a network side to the UE via higher-layer signaling, or predefined between the network side and the UE in a protocol, or determined according to a frequency mapping interval or a frequency mapping density at which the pilots are transmitted with the comb-like pattern, or the number of UEs for which multiplex pilots are in the same symbol with the comb-like pattern.
