Embodiment Construction

[0027] As described in the background, in an LTE-A system, a UE can work on multiple aggregated uplink carriers at the same time. Therefore, in one uplink subframe, there may be multiple PUSCH transmissions on multiple uplink carriers at the same time. Compatible with the LTE system, the LTE-A system supports the transmission of UCI on the PUSCH, and it has been determined that the UCI is only transmitted on one PUSCH. When the UE is configured to transmit UCI on the PUSCH, and there are multiple PUSCH transmissions in one uplink subframe at the same time, there is no clear solution for how to determine which PUSCH the UCI is transmitted on. The embodiment of the present invention provides a method for configuring UCI to be transmitted on the PUSCH.

[0028] Such as image 3 As shown, it is a schematic flowchart of a method for configuring UCI information transmission proposed by an embodiment of the present invention. The method specifically includes the following steps:

Abstract

The embodiment of the invention discloses a configuring method and device for UCI (user class identifier) information transmission. By utilizing the technical scheme of the embodiment of the invention, the UCI is transmitted in a PUSCH (physical uplink shared channel) by UE (user equipment) in an LTE-A (long term evolution-advanced) carrier polymerizing system under the condition that the UE has a plurality of PUSCH schedule transmissions in an uplink sub-frame, and the problem of transmitting the UCI only in one PUSCH by UE in the LTE-A system when a plurality of PUSCH transmissions coexist in one uplink sub-frame is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a configuration method and equipment for UCI information transmission. Background technique [0002] For the Long Term Evolution multi-carrier system, in order to support a wider system bandwidth than the LTE (Long Term Evolution, Long Term Evolution) system, such as 100MHz, one possibility is to directly allocate 100M bandwidth spectrum, such as figure 1 One possibility is to aggregate some spectrum allocated to the existing system to form a large bandwidth for the long-term evolution multi-carrier system. At this time, the uplink and downlink carriers in the system can be configured asymmetrically, that is, users may occupy N≥ 1 carrier for downlink transmission, M≥1 carrier for uplink transmission, such as figure 2 shown. [0003] UCI (Uplink Control Information, uplink control information) information includes CQI (ChannelQuality Indicator, channel quality indicator...
