Description

A kind of Physical Uplink Shared Channel transmission method, device, terminal and base station

Technical field

The present invention relates to field of communication technology, a kind of Physical Uplink Shared Channel transmission method, device, terminal are particularly related to And base station.

Background technique

In LTE wireless communication system, aperiodic channel status information (A-CSI, Aperiodic Channel State Information it) is passed by Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) Defeated, base station eNodeB passes through Physical Downlink Control Channel (PDCCH, the Physical Downlink of dispatching uplink data Control CHannel) triggering terminal UE carries out A-CSI and reports.The downlink control used in the PDCCH of dispatching uplink data There are an information fields for triggering in information (DCI, Downlink Control Information) format (format) processed A-CSI is reported, and when information field instruction UE needs to report A-CSI, UE carries out A-CSI's on the PUSCH scheduled in the DCI It reports.

Support ascending control information (UCI, Uplink Control Information) and uplink shared in LTE system Channel (UL-SCH, UpLink Shared Channel) (shows as one or more transmission block (TB, Transport Block) transmitted on PUSCH, alternatively referred to as data) corresponding TB multiplexing transmission on PUSCH, or only UCI does not have at one It is transmitted on the PUSCH for having corresponding UL-SCH, i.e., PUSCH only transmits UCI at this time.

UCI includes hybrid automatic repeat-request confirmation message HARQ-ACK, channel state information CSI etc..ENodeB passes through Certain information fields in DCI format used in the PDCCH for dispatching PUSCH (i.e. uplink scheduling authorization UL grant) are set It indicates on PUSCH for special state without the corresponding TB of UL-SCH (i.e. there is only UCI).3GPP agreement TS36.213e40 8.6.2 it defines in section when meeting particular schedule condition, it is believed that the corresponding TB biography of no UL-SCH scheduled PUSCH on Defeated, i.e. there is only UCI on the PUSCH: such as PDCCH using DCI format 0 and modulation with coding strategy (MCS, Modulation Coding Scheme) grade is 29 and triggers the information field of CSI in the DCI and be 1 bit and be arranged to touch Hair A-CSI is reported, and when Physical Resource Block (PRB, Physical Resource Block) number is less than or equal to 4, or is made With DCI format 4 and only enable a TB and the TB that enable correspond to MCS grade be 29 and the transmission number of plies that indicates be 1 and When the information field for triggering CSI in DCI is that 1 bit and being arranged to triggers that aperiodic CSI is reported and PRB number is less than or equal to 4 When, etc..

When the corresponding TB multiplexing transmission on PUSCH of UCI and UL-SCH, UCI and the corresponding TB of UL-SCH use identical Order of modulation；When only UCI is when the corresponding TB of UL-SCH may be not present in PUSCH transmission, to the order of modulation that UCI is fixed, such as Order of modulation Qm=2, i.e., modulated using QPSK.

In NR, UCI may include more bit numbers, it is therefore desirable to support bigger order of modulation with improve its Efficiency of transmission on PUSCH.

It is solid to UCI it is, in LTE system, and when only transmitting UCI TB corresponding not comprising UL-SCH on PUSCH Surely it is modulated using the QPSK that order of modulation is 2.In NR system, A-CSI is uploaded in the PUSCH of the corresponding TB of no UL-SCH The defeated modulation system that higher order can be used determines that the order of modulation of UCI needs first to determine whether the PUSCH includes UL-SCH pairs How the TB answered still determines whether a PUSCH includes that there are no specific by the corresponding TB of UL-SCH at present in NR system Method.

From the foregoing, it will be observed that with the development and change of mobile communication business demand, ITU (International Telecommunication Union, International Telecommunication Union) and the tissues such as 3GPP all begin one's study new wireless communication system (such as 5G NR, 5Generation New RAT).At present in 5G NR, when A-CSI is triggered at one without corresponding UL- When transmitting on the PUSCH of SCH, the modulation order for being applied to have the PUSCH of corresponding UL-SCH is can be used in the order of modulation of A-CSI Number, it can use the high order modulations such as Qm=2 (corresponding QPSK), Qm4 (corresponding 16QAM), Qm=6 (corresponding 64QAM).Determine A- The order of modulation of CSI needs first to determine whether the PUSCH has corresponding UL-SCH still, how to determine that a PUSCH is at present It is no that comprising UL-SCH, there are no specific methods.
