Embodiment 1

[0082] The physical uplink shared channel is divided into the following two levels according to the order of priority of the physical uplink shared channel from high to low, and the physical uplink shared channels of the two levels are in order of priority from high to low:

[0083] Dynamically scheduled physical uplink shared channel;

[0084] Non-dynamically scheduled physical uplink shared channel.

[0085] Implementation method one

[0086] For the user equipment, in one subframe, there is at most one uplink scheduling grant signaling to trigger the aperiodic CSI report.

[0087] (1) If there is a dynamically scheduled PUSCH, select the dynamically scheduled PUSCH to carry UCI.

[0088] For the user equipment, in one subframe, when there are multiple dynamically scheduled PUSCHs, one of the PUSCHs is selected to carry UCI according to a predefined rule.

[0089] The predefined rule includes preferentially selecting the PUSCH scheduled by the uplink scheduling grant sign...

Embodiment 2

[0108] The physical uplink shared channel is divided into the following two levels according to the order of priority of the physical uplink shared channel from high to low, and the physical uplink shared channels of the two levels are in order of priority from high to low:

[0109] The physical uplink shared channel scheduled by the uplink scheduling grant signaling that triggers the aperiodic channel state information report;

[0110] Other physical uplink shared channels that do not meet the above-mentioned first-level conditions, such physical uplink shared channels include physical uplink shared channels scheduled by uplink scheduling authorization signaling that does not trigger aperiodic channel state information reporting, and non-dynamic scheduling physical uplink shared channel.

[0111] Implementation method one

[0112] For the user equipment, in one subframe, there is at most one uplink scheduling grant signaling to trigger the aperiodic CSI report.

[0113] (1)...

Embodiment 3

[0128] The physical uplink shared channels are divided into the following three levels according to the order of priority of the physical uplink shared channels from high to low, and the physical uplink shared channels of the three levels are in order of priority from high to low:

[0129] The physical uplink shared channel scheduled by the uplink scheduling grant signaling that triggers the aperiodic channel state information (CSI) report;

[0130] The physical uplink shared channel scheduled by the uplink scheduling grant signaling that does not trigger the aperiodic channel state information (CSI) report;

[0131] Non-dynamically scheduled physical uplink shared channel.

[0132] Implementation method one

[0133] For the user equipment, in one subframe, there is at most one uplink scheduling grant signaling to trigger the aperiodic CSI report.

[0134] (1) If there is an aperiodic CSI report, select the PUSCH scheduled by the uplink scheduling grant signaling that trigge...

Abstract

The invention discloses a method and user equipment for selecting a physical uplink sharing channel. The method comprises that: the user equipment selects a physical uplink sharing channel with the highest priority for bearing uplink control information from a plurality of physical uplink sharing channels sent on a subframe according to the priorities of the physical uplink sharing channels. The method effectively solves the problem that how to select a PUSCH for bearing the UCI from a plurality of PUSCH by the user equipment in the LET-A system, so when the user equipment sends a plurality of PUSCH on a subframe and the UCI is needed to be borne on the PUSCH for transmission, the user equipment can uniquely determine the PUSCH for bearing the UCI, the UCI transmission performance is ensured, and the influence on uplink data is reduced as much as possible.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for selecting a physical uplink shared channel and user equipment. Background technique [0002] In the 3rd Generation Partnership Project Long Term Evolution system (The 3rd Generation Partnership Project Long Term Evolution, referred to as 3GPP LTE), the user equipment (User Equipment, referred to as UE) sends the uplink control information (Uplink Control Information (UCI for short) includes: Acknowledgment / Negative Acknowledgment (ACK / NACK) for Physical Downlink Shared Channel (PDSCH for short), Channel State Information (Channel State Information) for downlink channel , referred to as CSI) and so on. [0003] Wherein, the UE obtains channel state information CSI of the downlink channel according to a downlink reference signal (reference signal), and then reports the obtained CSI to the base station. Based on the CSI fed back by the UE, the base statio...
