To use this spectrum, there is no need to apply for a proprietary spectrum authorization from the government.
- some countries or regions have stipulated the regulatory requirements that must be met to use the unlicensed spectrum. For example, in some areas, communication equipment follows the principle of "listen first, speak first", that is, communication equipment needs to perform channel detection before transmitting signals on channels of unlicensed spectrum.
- the communication device can only perform signal transmission; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot perform signal transmission. In order to ensure fairness, in one transmission, the time that the communication device uses the unlicensed spectrum channel for signal transmission cannot exceed the maximum channel occupation time (Maximum Channel Occupation Time, MCOT).

- the base station A indicates the group information to which the PDSCH scheduled by the DCI or the PDCCH carrying the DCI belongs through the downlink control information DCI.
- base station A sends trigger signaling to instruct terminal device B to feed back the ACK/NACK information corresponding to a certain group, terminal device B will belong to all PDSCHs or PDCCHs (Physical Downlink Control CHannel) corresponding to the group.

Description
本申请涉及通信技术领域,尤其涉及一种信息接收的方法、发送的方法、装置和设备。
当终端设备接收到一个下行控制信息(Downlink control information,DCI)格式1_1时,该DCI触发终端设备发送type-3 HARQ-ACK codebook(type-3 Hybrid Automatic Repeat request-Acknowledgement codebook,类型3混合自动重传请求-肯定确认码本),codebook(码本)中包括所有HARQ(Hybrid Automatic Repeat request,混合自动重传请求)进程的反馈信息;或者,该触发终端设备发送enhanced type-2 HARQ-ACK codebook(enhanced type-2 Hybrid Automatic Repeat request-Acknowledgement codebook,增强类型2混合自动重传请求-肯定确认码本),该codebook中包括2个PDSCH groups(Physical Downlink Shared Channel groups,物理下行共享信道组)中所有PDSCH(Physical Downlink Shared Channel,物理下行共享信道)对应的ACK(Acknowledgement,肯定确认)/NACK(Negative Acknowledgement,否定确认)信息,表示基站期待终端把所有调度的PDSCH对应的ACK/NACK信息发送给基站。
但当该DCI中的PDSCH-to-HARQ_feedback timing indicator(物理下行共享信道至混合自动重传请求反馈定时指示器)信息域的指示结果为无效值时,表示基站未指示有效的传输反馈信息的时域资源。这种指示结果本身是不合理的调度指示,即要求终端设备发送反馈信息,但却不指示反馈信息的传输资源。因此,存在着系统效率低,终端设备功耗浪费的技术问题。

图1为本申请以下具体实施方式可能应用的通信系统的系统架构。该系统架构包括:基站A,终端设备B。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱通常被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存,一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如,在一些地区,通信设备遵循“先听后说”原则,即通信设备在免授权频谱的信道上进行信号发送前,需要先进行信道侦听,只有当信道侦听结果为信道空闲时,该通信设备才能进行信号发送;如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙,该通信设备不能进行信号发送。为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time,MCOT)。随着无线通信技术的发展,LTE(Long Term Evolution,长期演进)系统和NR(new radio,新无线)系统都会考虑 在免授权频谱上布网,以利用免授权频谱来进行数据业务的传输。
Rel-16(Release 16,第16版本)NR-U(NR-based Access to Unlicensed Spectrum,基于NR的非授权频段接入)支持多种HARQ-ACK(Hybrid Automatic Repeat request-Acknowledgement,混合自动重传请求-肯定确认)码本(codebook)生成方式,包括:Type-1 HARQ-ACK codebook(类型1混合自动重传请求-肯定确认码本)、Type-2 HARQ-ACK codebook(类型2混合自动重传请求-肯定确认码本)、Enhanced Type-2 HARQ-ACK codebook、Type-3 HARQ-ACK codebook(类型3混合自动重传请求-肯定确认码本),其中Type-1、Type-2码本是NR Rel-15(Release 15,第15版本)支持的两种反馈信息码本,而Enhanced Type-2和Type-3码本是Rel-16 NR-U新引入的两种反馈信息码本。终端设备B基于基站发送的高层信令确实所使用的codebook,其中,Type-1、Type-2、Enhanced Type-2码本不会同时配置,而Type 3码本可以独立于Type-1、Type-2、Enhanced Type-2配置(即可叠加配置)。
Enhanced Type-2 HARQ-ACK codebook为基于下行信道组的ACK/NACK反馈方式,目前指示最大两个下行信道组。基站A通过下行控制信息DCI指示该DCI调度的PDSCH或承载该DCI的PDCCH所属于的组信息。当基站A发送触发信令,指示终端设备B反馈某个组对应的ACK/NACK信息时,则终端设备B将属于该组的所有PDSCH或PDCCH(Physical Downlink Control CHannel,物理下行控制信道)对应的反馈信息一起反馈给基站A。基站A可以多次触发终端设备B发送某一个组的ACK/NACK信息,即实现ACK/NACK重传。3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)确定在DCI格式1_1中包括:PDSCH group index(物理下行共享信道组索引)信息域,用于指示该DCI对应的下行信道所述的组信息;Number of requested PDSCH group(s)(物理下行共享信道组数目请求)信息域,用于指示该DCI触发进行反馈的信道组信息,该比特指“0”表示触发传输当前DCI对应下行信道所在的信道组的反馈信息,该比特指“1”表示触发传输两个信道组的反馈信息。而DCI格式1_0中不包括触发信道组指示信息。
Type-3 HARQ-ACK codebook包括全部HARQ进程对应的ACK/NACK 反馈的方式。具体的,终端设备B支持最大N个HARQ进程。当基站A触发终端设备B进行全进程反馈时,不论终端设备B实际收到多少个HARQ进程,总是将向基站A反馈N个进程对应的ACK/NACK反馈信息。ACK/NACK信息可以按照HARQ进程编号顺序映射到反馈信息码本(codebook)中。未接收到的HARQ进程对应的ACK/NACK信息设置为占位信息(如NACK)。假设终端设备B最大支持8个HARQ进程,一个HARQ进程每次通过一个PDSCH传输。终端设备B支持的最大传输块TB(transport block)数量为2(即一个PDSCH中最多承载2个TB),每个TB对应独立的ACK/NACK反馈信息。终端设备B接收到HARQ进程3、7、4,当基站A触发终端设备B进行全进程反馈时,终端设备B在PUCCH(Physical Uplink Control Channel,物理上行控制信道)内传输{NACK

HARQi,TBj表示HARQ进程i中TBj对应的ACK/NACK反馈信息。目前确定全进程反馈可以通过DCI格式1_1触发,该DCI中可以同时同于调度至少一个PDSCH传输或者不调度任何PDSCH传输(即只用于触发全进程反馈)。
目前3GPP确定,对于Type-2 HARQ-ACK codebook和Enhanced Type-2 HARQ-ACK codebook其DCI格式1_1中可以PDSCH-to-HARQ_feedback timing indicator信息域的指示结果集合中可以包括一个无效值。若当前DCI格式1_1中的PDSCH-to-HARQ_feedback timing indicator信息域指示的是非无效值,终端设备B根据该指示确定传输ACK/NACK信息的时隙或子时隙。若当前DCI格式1_1中的PDSCH-to-HARQ_feedback timing indicator指示的是无效值,表示暂不反馈该DCI调度的PDSCH或承载该DCI的PDCCH对应的ACK/NACK信息。
综上所述,对于Enhanced Type-2 HARQ-ACK codebook,DCI格式1_1在调度一个下行信道的同时触发传输两个信道组中所有下行信道的反馈信息,或者,对于Type-3 HARQ-ACK codebook,DCI格式1_1触发传输全部HARQ进程的反馈信息,表示基站A期待终端设备B把所有调度的PDSCH对 应的ACK/NACK信息发送给基站A。但若该DCI中的PDSCH-to-HARQ_feedback timing indicator指示的无效值,表示基站A未指示有效的传输反馈信息的时域资源。这种指示结果本身是不合理、矛盾的。因此,存在着系统效率低,终端设备功耗浪费的技术问题。
本申请以下具体实施方式将详细描述如何保证第一DCI中的第一信息域的指示结果为有效值,解决了系统效率低,终端设备功耗浪费的技术问题。
