Embodiment Construction

[0129] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0130] The present invention aims at the problem that it is impossible to determine whether the PUSCH contains UL-SCH in the existing technology, resulting in the problem that the PUSCH cannot be transmitted normally, and provides a physical uplink shared channel transmission method, which can be applied to terminals, such as figure 1 shown, including:

[0131] Step 11: Receive the physical downlink control channel PDCCH transmitted using the preset downlink control information DCI format;

[0132] Step 12: Determine whether the physical uplink shared channel PUSCH corresponding to the PDCCH contains data at least according to the indication information in the new data indication NDI indication field and the modulation and coding strategy MCS indication ...

Abstract

The invention provides a physical uplink shared channel transmission method and device, a terminal and a base station, and the method comprises the steps: receiving a physical downlink control channel(PDCCH) transmitted by using a preset downlink control information (DCI) format; and determining whether a physical uplink shared channel (PUSCH) corresponding to the PDCCH contains data or not at least according to indication information in a new data indication (NDI) indication domain and a modulation and coding strategy (MCS) indication domain in a DCI format used by the PDCCH. According to the scheme, multiple indication domain combinations in existing DCI are reused for judgment, and meanwhile it is judged that the PUSCH does not contain UL-. When the SCH corresponds to the TB, the modulation order of the UCI on the PUSCH can be further determined according to the MCS indication domain, and normal transmission of the PUSCH only bearing the UCI is achieved on the basis that the DCI indication overhead is not increased; the problem that in the prior art, whether a PUSCH contains UL-or not cannot be determined is well solved. And the SCH causes that the PUSCH cannot transmit normally.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a physical uplink shared channel transmission method, device, terminal and base station. Background technique [0002] In the LTE wireless communication system, the aperiodic channel state information (A-CSI, Aperiodic Channel State Information) is transmitted through the Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel), and the base station eNodeB uses the Physical Downlink Control Channel (PDCCH) to schedule uplink data , Physical DownlinkControl CHannel) triggers the terminal UE to report the A-CSI. There is an information field in the downlink control information (DCI, Downlink Control Information) format (format) used by the PDCCH for scheduling uplink data to trigger A-CSI reporting. When the information field indicates that the UE needs to report A-CSI, the UE The A-CSI is reported on the PUSCH scheduled by the DCI. [0003] In the LT...
