Description

A kind of PUCCH method and apparatus in the carrier aggregation of enhancing

Technical field

The present invention relates to the ascending power control method in the dual link communication in mobile communication technology field and device, particularly relate to the uplink power control scheme in the scene of the CA (Carrier Aggregation, carrier aggregation) enhancing (Enhancement) in Long Term Evolution (LTE Long Term Evolusion) system.

Background technology

Traditional 3GPP (3rd Generation Partner Project, third generation partner program) the LTE system R (Release that formulates, version) in 10, CA is introduced into as one of key technology, its core concept is that subscriber equipment (UE-User Equipment) can work over a number of carriers simultaneously, and CA can improve the peak rate of single UE.In LTE CA, UE is configured a Pcell (Primary Cell, main Serving cell), one or more Scell (Secondary Cell, auxiliary serving cell).For FDD (Frequency Duplex Division, FDD) LTE, a Serving cell includes at least one descending carrier in { descending carrier, a up-link carrier }.For TDD (Time Duplex Division, time division duplex) LTE, a Serving cell includes a carrier wave.In LTE R10, support that the UE of CA is at best able to be configured 5 Serving cells, and UE can only send PUCCH information on Pcell.In 3GPP R10, CA supports that sending downlink signaling across carrier dispatching, i.e. base station at first carrier dispatches the transmission of wireless signals on the second carrier wave.Base station utilizes the target carrier that CIF (Carrier Indicator Field, the carrier wave instructions field) instruction in DCI (Downlink Control Information, Downlink Control Information) is to be dispatched.CIF is by 3 the bit instructions being positioned at DCI head.

At 3GPP RAN (Radio Access Network, wireless access network) the 66th plenary session (Plenary) passed through a new research topic (RP-142286), is i.e. abbreviated as eCA in the present invention more than CA enhancing-this problem of 5 carrier waves.In eCA, the maximum Serving cell number supported rises to 32.

In tradition CA, subscriber equipment (UE-User Equipment) can only send PUCCH (Physical Uplink Control Channel on Pcell, Physical Uplink Control Channel), a key technology of eCA is that UE can send PUCCH on multiple Serving cells.

Summary of the invention

In view of UCI (Uplink Control Information (for most 32 Serving cells) in eCA, ascending control information) shared by Radio Resource may bigger-in the present invention, UCI is { SR (Scheduling Request, dispatch request), HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) _ ACK (response), CSI (Channel Status Information, channel condition information) } general designation., inventor is likely in eCA by one or more in the research following transmitting scene of discovery to be occurred:

UCI is sent on the PUCCH of-transmitting scene one .UE multiple Serving cells in given subframe

Send SR or HARQ_ACK (i.e. ACK/NACK) on-transmitting scene two .UE at least first service community PUSCH in given subframe, the PUCCH of at least second service community in described given subframe sends CSI

UCI is sent on the PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) of-transmitting scene three .UE multiple Serving cells in given subframe.

The LTE CA that above-mentioned three kinds of transmitting scenes are all traditional does not supports.Inventor is by further study show that: at uplink transmission power by limited time, and how to perform power clip operation for the UCI of transmission on multiple Serving cells is a problem needing to solve.In dual link (Dual Connectivity) communicates, each base station is completely independent scheduling, thus has evaded the problems referred to above.

The effect played in wireless transmissions in view of different types of UCI is different, and the transmit power needed for first meeting the UCI bigger on being wirelessly transferred impact can minimize limited the brought impact of transmit power.

According to above-mentioned analysis, the invention discloses a kind of method in UE, wherein, comprise the steps:

-step A. sends first group of wireless signal in the first subframe on first group of Serving cell.Sending second group of wireless signal on second group of Serving cell in the first subframe, wherein the maximum general power that sends is more than the first ideal general power；Or keeping zero transmit power on second group of Serving cell in the first subframe, wherein the maximum general power that sends is not more than the first preferable general power.
