Embodiment Construction

[0021] In the following detailed description, reference is made to the accompanying drawings which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. It is to be readily understood that aspects of the disclosure may be arranged, substituted, combined and designed in various configurations, all of which are expressly contemplated and constitute a part of this disclosure.

[0022] As mentioned above, UCI multiplexing in PUSCH has been adopted in NR (eg, Release 15). figure 1 An exemplary scenario of UCI multiplexing in PUSCH in NR is schematically shown. exist figure 1 In , the axis pointing to the right represents the time axis, and the label of the transmission time interval (TTI) is indicated on it, the block filled with left slash represents the downlink (DL) allocation from the base station (gNB), and the block filled with the right Blocks filled with slashes represent UL grants from the base sta...

Abstract

Provided are user equipment, base station and wireless communication methods related to multiplexing of UCI in PUSCH in NR. A user equipment comprises: circuitry operative to process UCI bits to be transmitted according to the comparison of the number M of UCI bits generated based on DL assignment (s) before an UL grant from a base station and the number N of UCI bits generated based on DL assignment (s) after the UL grant with the number P of UCI bits indicated in the UL grant and / or the maximum number Q of bits determined based on at least a configured coding rate, wherein each of M, N, P, Qis an integer equal to or larger than 0; and a transmitter operative to transmit the processed UCI bits in PUSCH at a TTI indicated in the UL grant to the base station.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to the multiplexing of Uplink Control Information (UCI) in Physical Uplink Shared Channel (PUSCH) in NR (New Radio access technology, new radio access technology) Relevant user equipment (userequipment, UE), base station (gNB) and wireless communication method. Background technique [0002] As is well known in the art, the UCI is reported by the UE to the base station (base station, BS), and may be a Hybrid Automatic Repeat request-Acknowledgment (HARQ-ACK) or such as a Channel Quality Indicator (Channel Quality Indicator, CQI), rank indicator (Rank Indication, RI) or channel state information (Channel State Information, CSI) of precoding matrix indicator (Precoding Matrix Indicator, PMI). Also, UCI may be sent in a physical uplink control channel (Physical Uplink ControlChannel, PUCCH) or PUSCH. When sent in PUSCH, UCI will occupy some data channel resource elem...
