Embodiment Construction

[0038] The present invention provides an uplink control information transmission method, and its implementation is as follows figure 2 As shown, when the UE is configured to use PUCCH format 3 to transmit ACK / NACK information and does not receive the PDCCH indicating the PUCCH format 3 channel resources corresponding to the ACK / NACK, or when the UE is configured with more than 1 carrier And it is configured to use PUCCH format 1b with channelselection to transmit ACK / NACK information, including the following operations:

[0039] Step 100: The aforementioned UE generates ACK / NACK information;

[0040] Step 110: The foregoing UE generates periodic CSI;

[0041] Step 120: The UE transmits the periodic CSI and the ACK / NACK information in the same uplink subframe on the channel resource corresponding to the periodic CSI.

[0042] Among them, for the scenario where the UE is configured to use PUCCH format 3 to transmit ACK / NACK information, and does not receive the PDCCH indicating the PUC...

Abstract

The invention discloses an uplink control information transmission method and device. A UE side method comprises the steps that when UE is configured to use a PUCCH format 3 for transmitting ACK / NACK information and does not receive a PDCCH used for indicating a PUCCH format 3 channel resource corresponding to ACK / NACK, or when more than one carrier is configured on the UE and the UE is configured to use a PUCCH format 1b with channel selection for transmitting the ACK / NACK information, the UE generates the ACK / NACK information; period channel state information (CSI) is generated; the period CSI and the ACK / NACK information are transmitted on a channel resource corresponding to the period CSI through the same uplink subframe. The uplink control information transmission method and device prevent the period CSI from being discarded and improve the accuracy of downlink scheduling of a base station.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting uplink control information. Background technique [0002] In the LTE-A (Long Term Evolution-Advanced) system, the peak rate of the system is significantly higher than that of the LTE (Long Term Evolution) system, requiring a downlink 1Gbps and an uplink 500Mbps. Therefore, the LTE-A system needs to expand the available bandwidth of the terminal, that is, to aggregate multiple continuous or discontinuous carriers under the same eNB (base station), and simultaneously serve the UE (User Equipment, user equipment, or terminal equipment). Provide the required rate, such as figure 1 Shown. These aggregated carriers are also called component carriers (CC, Component Carrier). Each cell can be a component carrier, and cells (component carriers) under different eNBs cannot be aggregated. In order to ensure that the UE in the LTE system can ...
