Example Embodiment

[0054] As mentioned above, the current method for transmitting uplink signals will generate a large number of invalid redundant uplink signal transmissions, and bring unnecessary energy consumption and signaling overhead.

[0055] In order to solve the above problem, the user equipment in this embodiment of the present invention acquires a preferred beam combination set including the preferred beam combination, and then only transmits uplink signals on the preferred beam combination, and the quality of signal transmission on the preferred beam combination is higher than that of the preferred beam combination. The preset quality threshold does not require full-coverage uplink signal transmission for all beam combinations, so invalid and redundant uplink signal transmission and unnecessary energy consumption signaling overhead can be avoided, and the efficiency of uplink signal transmission can be improved.

[0056] In order to make the above objects, features and advantages of t...

Abstract

The invention provides a method, user equipment and base station for transmitting upstream signals. The method comprises the following steps: acquiring an optimized beam combination set which belongs to the set formed by all beam combinations between the user equipment and the base station and comprises optimized beam combinations having the signal transmission quality higher than a preset quality threshold; and transmitting upstream signals on the optimized beam combinations. By adopting the scheme, invalid redundant upstream signal transmission and unnecessary energy consumption signaling cost can be avoided, and the upstream signal transmission efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method for uplink signal transmission, user equipment and a base station. Background technique [0002] In the discussion on 3GPP Rel-14, it is proposed that a user equipment (User Equipment, UE) triggers the uplink mobility control mechanism of the communication system by sending an uplink signal. In this mechanism, the UE periodically sends uplink signals to the base station side, and each base station side device comprehensively judges the mobility control problem of the UE based on the quality of the received uplink signal, and then the base station side feeds back the uplink mobility control results obtained through comprehensive judgment to the The UE, based on the result fed back from the base station side, the UE chooses to perform operations such as continuing to camp, reselecting, or switching cells. The above-mentioned mechanism can utilize the UE...
