Uplink Signal Sending Method and User Equipment

An uplink signal transmitting method applied to a carrier aggregation system, comprising:

• after configuring more than two timing advances, a user equipment (UE), according to predefined rules, transmitting at least one of uplink channels and uplink signals in which symbols are to be overlapped in a time domain on different carriers;
• wherein, said predefined rules comprise triggering rules and transmitting rules, and said at least one of said uplink channels and uplink signals being processed according to said transmitting rules only when at least one of the triggering rules is met;
• wherein
• when one of the triggering rules is the difference of timing advance values of different uplink carriers configured by said eNB for said UE exceeding a first preset threshold value, transmitting at least one of uplink channels and uplink signals in which symbols are to be overlapped in a time domain on different carriers after rate-matching processing on at least one of the uplink channels and uplink signals;
• when one of the trigger rules is said UE finding out that the difference of the actual transmitting time of said configured different uplink carriers exceeding a second preset threshold value, transmitting at least one of uplink channels and uplink signals in which symbols are to be overlapped in a time domain on different carriers after discarding at least one of said uplink channels and uplink signals;
• wherein, said transmitting rules comprise:
• when said uplink channels and/or uplink data in which symbols are to be overlapped in a time domain on different carriers are same or different, the UE, transmitting said same or different uplink channels and/or uplink data after rate-matching processing on same or different uplink channels and/or uplink data;
• transmitting after discarding same or different uplink channels and/or uplink data, or simultaneously transmitting same or different uplink channels and/or uplink data;
• wherein,
• when said uplink channels in which symbols are to be overlapped in a time domain on different carriers are PUSCHs, the UE, according to priorities of sub-frame index of said uplink channels, transmitting said uplink channels;
• when said uplink channels in which symbols are to be overlapped in a time domain on different carriers are PUSCH and PUCCH, the UE, according to priorities of said uplink channels;
• transmitting said uplink channels;
• when said uplink channels and/or uplink data are PUCCH, PUCCH and/or SRS, the UE, transmitting said uplink channels and/or uplink data after discarding said uplink channels and/or uplink data, or simultaneously transmitting said uplink channels and/or uplink data.

A user equipment applied to a carrier aggregation system, comprising:

• a receiving module, configured to receive more than two timing advances configured by an evolved NodeB;
• a transmitting module, configured to transmit after performing rate matching for the uplink channels and/or uplink signals in which symbols are overlapped in the time domain on different carriers, or to transmit the uplink channels and/or uplink signals after discarding, or to simultaneously transmit said uplink channels and/or uplink signals according to predetermined rules sent from the NodeB;
• wherein,
• said predefines rules comprise transmitting rules, said transmitting module is further configured to:
• said transmitting rules comprising:
• when said uplink channels in which symbols are to be overlapped in a time domain on different carriers are same, the UE, according to priorities of said uplink channels, transmitting said uplink channels after rate-matching processing on the uplink channels;
• transmitting after discarding said uplink channels, or simultaneously transmitting said uplink channels;
• wherein, the priorities of said uplink channels comprise:
• the priorities determined by sub-frame index of said uplink channels;
• wherein, the priority in the latter sub-frame is higher than that of in the former sub-frame;
• or
• the priority in a former sub-frame is higher than that of in a latter sub-frame.
