- TRP Transmission Reception Point
- NR provides an uplink scheduling request (Scheduling Request, SR) mechanism.
- Scheduling Request SR
- the UE tells the network side whether it needs uplink resources for uplink shared channel (Uplink-Shared Channel, UL-SCH) transmission through the SR, but does not tell the network side how much uplink data needs to be sent (this is reported through the buffer status report BSR of).
- uplink resources for uplink shared channel (Uplink-Shared Channel, UL-SCH) transmission through the SR, but does not tell the network side how much uplink data needs to be sent (this is reported through the buffer status report BSR of).
- UL-SCH Uplink-Shared Channel
- the usual practice is to allocate at least enough resources for the UE to send the BSR.
- the above UL-SCH has a corresponding relationship with a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).
- the network side does not know when the UE needs to send uplink data, that is, when the UE will send the SR. Therefore, the network side needs to detect whether there is an SR report on the allocated SR resources.

- Random access SR transmission obtain uplink resources through a random access process.
- 5G systems allow network terminals to configure multiple sets of dedicated SR resources, select SR resources among them according to different services, and configure the mapping relationship between each logical channel and dedicated SR resources.
- the terminal Once the terminal has a regular BSR trigger, the terminal first determines the logical channel that triggers the regular BSR, and then selects and determines the available dedicated SR resource according to the mapping relationship between the logical channel and the dedicated SR resource, and sends the SR using the resource. If the logical channel that triggers the regular BSR is not configured with dedicated SR resources, it will trigger the terminal to initiate a random access SR. Once the random access SR is triggered, all suspended SRs need to be cancelled.
- any set of dedicated SRs of the terminal reaches the maximum number of transmissions, a random access SR will also be triggered.
- the terminal After the dedicated SR fails, the terminal also needs to perform a series of processes, including notifying the RRC layer to release PUCCH resources corresponding to all serving cells, notifying the RRC layer to release SRS resources corresponding to all serving cells, and clearing the uplink/downlink semi-persistent scheduling resources.
- MAC entities can be configured with 0, 1 or more SR configurations.

- Each SR configuration corresponds to one or more logical channels.
- Each logical channel can correspond to 0 or 1 SR. These are configured by RRC signaling.
- the SR that is triggered and not sent is considered a pending SR, that is, an SR in a suspended state.
- the UE sends the SR because there is no uplink PUSCH resource, so the UE can only send the SR on the PUCCH.
- the network side may allocate a dedicated SR resource for each UE to send SR.
- the SR resource is periodic, and appears every n time slots or symbols.
- the UE triggers an SR and sends the SR on the next nearest SR transmission opportunity. Then the UE receives the UL authorization and sends it on the PUSCH (UL-SCH) indicated by the UL authorization
- the data sent generally refers to the data packet containing the BSR.
- the UE After the UE receives the downlink DL data, the UE needs to perform HARQ feedback in the UL.

- the channel is a logical channel that triggers SR
- the first logical channel is a logical channel for acquiring data transmitted by the uplink shared channel resource.

It is generally believed that the shorter the maxPUSCH-Duration, the shorter the delay required for the logical channel.
- Step 2 The terminal device receives the configuration information of the logical channel sent by the network side device.

- the logical channel corresponding to the current SR configuration is logical channel 1
- the parameter maxPUSCH-Duration of logical channel 1 is 0.25 time slots
- the current overlaps with it, or the logical channel configuration of the UL-SCH transmission data obtained by collision maxPUSCH-Duration is 0.5 time slots. Since 0.25 time slots are less than 0.5 time slots, it is considered that the SR configuration can be sent in preference to the UL-SCH, and the physical layer sends the SR.

相关申请的交叉引用
本申请主张在2018年12月6日在中国提交的中国专利申请No.201811486761.7的优先权、以及在2019年1月17日在中国提交的中国专利申请No.201910043921.9的优先权,上述两个申请的全部内容通过引用包含于此。
本公开涉及通信应用的技术领域,尤其涉及一种传输方法及终端。
在相关技术中,上行调度请求(Scheduling Request,SR)或者混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈,如果和物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输发生碰撞,或者,两个PUSCH传输发生碰撞,例如在时间上重叠,此时,用户设备(User Equipment,UE)会选择优先发送PUSCH,或将HARQ反馈或CSI复用到PUSCH信道上,停止PUCCH(Physical Uplink Control Channel,PUCCH)信道发送,进而在下一个可用的SR资源上发送触发的SR,或丢弃HARQ反馈信息。但是这样会造成一些紧急业务的SR被延迟发送或HARQ反馈时延增加的问题。例如,当SR是为紧急业务配置时,比如是为低时延高可靠URLLC业务配置的SR,这样会造成SR的发送延迟,进而影响网络侧调度缓存状态报告(Buffer Status Report,BSR),从而影响对时延要求较高业务的时延。
又例如,URLLC业务配置为配置授权类型1的传输方式,增强移动宽带eMBB业务会配置为动态授权方式进行传输。而URLLC对时延要求更高,eMBB业务对时延较低。但相关技术中的做法是,当配置授权与动态授权资源相碰撞或重叠时,UE会优先发送动态授权,这样会对延时要求较高的业务造成更大的延迟。
根据上述描述可知,在资源重叠的情况下,相关技术中的传输方案会影 响时延要求较高业务的发送时延,进而对业务的性能产生影响。

参见图1,图1是本公开实施例可应用的一种网络系统的结构图,如图1所示,包括终端11和网络侧设备12,其中,终端11可以是用户终端(User Equipment,UE)或者其他终端设备,例如:可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定终端11的具体类型。网络侧设备12可以是基站,例如宏站、LTE eNB、5G NR NB等;网络侧设备也可以是小站,如低功率节点(Low Power Node,LPN)、pico、femto等小站,或者网络侧设备可以接入点(Access Point,AP);基站也可以是中央单元(Central Unit,CU)与其管理是和控制的多个传输接收点(Transmission Reception Point,TRP)共同组成的网络节点。需要说明的是,在本公开实施例中并不限定网络侧设备的具体类型。
为使本领域技术人员能够更好地理解本公开实施例的技术方案,先对SR和HARQ反馈进行如下说明。
1)调度请求。
如果用户设备没有上行数据要传输,网络侧并不需要为该UE分配上行资源,否则会造成资源的浪费。因此,UE需要告诉网络侧自己是否有上行数据需要传输,以便网络侧决定是否给UE分配上行资源。为此NR提供了一个上行调度请求(Scheduling Request,SR)的机制。
UE通过SR告诉网络侧是否需要上行资源以便用于上行共享信道(Uplink-Shared Channel,UL-SCH)传输,但并不会告诉网络侧有多少上行数据需要发送(这是通过缓存状态报告BSR上报的)。网络侧收到SR后,给UE分配多少上行资源取决于网络侧的实现,通常的做法是至少分配足够UE发送BSR的资源。其中,上述UL-SCH是与物理上行共享信道(Physical Uplink Shared Channel,PUSCH)存在对应关系的。
网络侧不知道UE什么时候需要发送上行数据,即不知道UE什么时候会发送SR。因此,网络侧需要在已经分配的SR资源上检测是否有SR上报。
SR传输有两种形式:
专用SR传输:使用网络配置的物理上行控制信道(Physical Uplink Control Channel,PUCCH)专用资源。
随机接入SR传输:通过随机接入过程获取上行资源。
考虑到不同业务具有不同的时延要求,5G系统中允许网络终端配置多套专用SR资源,根据不同业务选择其中的SR资源,还可以配置每个逻辑信道和专用SR资源的映射关系。终端一旦有常规BSR触发,则终端首先确定触发常规BSR的逻辑信道,然后根据该逻辑信道和专用SR资源的映射关系选择确定可用的专用SR资源,并利用该资源发送SR。如果触发常规BSR的逻辑信道没有配置专用SR资源,将会触发终端发起随机接入SR。一旦随机接入SR触发,需要取消所有挂起的SR。
此外,终端任何一套专用SR达到最大传输次数后,也会触发随机接入SR。并且专用SR失败后,终端还需要进行一系列处理,包括通知RRC层释放所有服务小区对应的PUCCH资源、通知RRC层释放所有服务小区对应的SRS资源,清空上/下行半持续调度的资源。
媒体接入控制(Media Access Control,MAC)实体可以被配置0个,1个或多个SR配置。一个SR配置包括多个带宽部分BWP和小区上的一系列 PUCCH资源。对于一个逻辑信道,每个BWP上最多只能配置一个PUCCH资源。
每一个SR配置对应1个或多个逻辑信道。每个逻辑信道可以对应0个或1个SR。这些由RRC信令配置。
其中,这里认为触发的且没有被发送的SR为pending(等待)SR,也即处于挂起状态的SR。
UE是因为没有上行PUSCH资源才发送SR的,所以UE只能在PUCCH上发送SR。网络侧可以为每个UE分配一个专用的SR资源用于发送SR。该SR资源是周期性的,每n个时隙或符号出现一次。
如图2所示,UE在数据到达后,触发了一个SR,并在下一个最近的SR传输机会上发送了SR,接着UE收到了UL授权,并在UL授权指示的PUSCH(UL-SCH)上发送了数据,一般是指包含BSR的数据包。
2)HARQ反馈。
在UE接收到了下行DL数据后,UE需要在UL进行HARQ反馈。对于时延要求较高的业务,其HARQ反馈的时延要求也要高于普通业务,比如URLLC业务的HARQ反馈时延要求,要高于eMBB业务的HARQ反馈时延需求。
如图3所示,本公开实施例提供了一种传输方法,应用于终端,包括:
步骤301:在第一传输资源与第二传输资源重叠时,在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道。
其中,所述第一逻辑信道与所述第一传输资源对应,所述第二逻辑信道与所述第二传输资源对应。
具体的,上述第一逻辑信道是与在第一传输资源上传输的媒体接入控制分组数据单元MAC PDU所对应的逻辑信道,第二逻辑信道是与在第二传输资源上传输的MAC PDU所对应的逻辑信道。
这里,第一传输资源为控制信息的传输资源,所述第二传输资源为上行共享信道资源;或者,所述第一传输资源和所述第二传输资源均为上行共享信道资源。上述资源重叠可以具体是资源在时域上重叠。
上述控制信息包括调度请求SR、混合自动重传请求HARQ反馈信息和 信道状态信息CSI中的至少一项。这里的CSI是基于网络下行控制信息DCI指示的。
其中,在所述第一传输资源为SR的传输资源时,所述第一逻辑信道为所述SR的调度请求配置对应的逻辑信道,或触发SR的逻辑信道。
这里,BSR触发SR,使得SR变为已触发或挂起状态,触发所述BSR的逻辑信道所对应的SR配置是对应所述已触发或挂起SR的SR配置,即触发所述BSR的逻辑信道是触发SR的逻辑信道;
在所述第一传输资源为上行共享信道资源时,所述第一逻辑信道为获取所述上行共享信道资源所传输数据的逻辑信道。
且,上述时延要求较高的逻辑信道是指要求传输时延较低的逻辑信道。
步骤302:指示物理层在确定的逻辑信道对应的传输资源上发送数据。
例如,第一逻辑信道为时延要求较高的逻辑信道,则在第一传输资源上发送数据,即优先发送第一逻辑信道数据,第二逻辑信道为时延要求较高的逻辑信道,则在第二传输资源上发送数据,即优先发送第二逻辑信道数据。
本公开实施例的传输方法,在第一传输资源与第二传输资源重叠时,在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道;指示物理层在确定的逻辑信道对应的传输资源上发送数据。本公开实施例中在资源重叠时,优先在时延要求较高的逻辑信道对应的传输资源上发送数据,从而解决了相关技术中的资源重叠的传输方案会影响时延要求较高业务的发送时延的问题。
进一步地,在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道,包括:
获取逻辑信道的配置信息,所述逻辑信道包括第一逻辑信道和第二逻辑信道;
根据所述逻辑信道的配置信息,在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道。
上述逻辑信道的配置信息用于指示逻辑信道的传输时延。
上述配置信息包括最大物理上行共享信道PUSCH的持续时间信息、子载波间隔SCS列表信息、调制与编码策略MCS列表信息、优先级信息和配 置授权信息中的至少一项。
其中,逻辑信道要求的时延越短,则将PUSCH的持续时间设置的较短;或设置较大的SCS长度;或允许使用配置授权类型1;或配置较高的优先级。
进一步地,在所述配置信息包括最大物理上行共享信道PUSCH的持续时间信息时;
所述在第一逻辑信道和第二逻辑信道中确定时延要求较低的逻辑信道对应的传输资源,包括:
在第一PUSCH的持续时间小于或者等于第二PUSCH的持续时间时,确定第一逻辑信道为时延要求较高的逻辑信道,否则,确定第二逻辑信道为时延要求较高的逻辑信道;
其中,第一PUSCH的持续时间为第一逻辑信道上配置的最大PUSCH持续时间;第二PUSCH的持续时间为第二逻辑信道上配置的最大PUSCH的持续时间。
下面结合实施例一来进行具体说明。
实施例一:上述第一传输资源为控制信息SR的传输资源,上述第二传输资源为上行共享信道资源。
步骤一:网络侧设备向终端设备发送逻辑信道的配置信息。所述配置信息中包括最大PUSCH的持续时间信息。
举例来讲,对于逻辑信道1,其参数最大PUSCH的持续时间maxPUSCH-Duration为0.5个时隙,表示该逻辑信道能够使用的上行授权的PUSCH持续时间最大为0.5个时隙;对于逻辑信道2,其参数maxPUSCH-Duration为0.25个时隙,表示该逻辑信道能够使用的上行授权的PUSCH持续时间最大为0.25个时隙。一般认为,maxPUSCH-Duration越短,则表示该逻辑信道要求的时延越短。
步骤二:终端设备接收网络侧设备发送的逻辑信道的配置信息。
步骤三:当终端设备至少一个SR处于挂起状态时,MAC实体将针对每个挂起的SR:
参见图4,在当前挂起SR的SR配置的PUCCH资源与UL-SCH重叠时,如果SR配置对应的第一逻辑信道的第一PUSCH的持续时间小于或者等于所 述UL-SCH对应的第二逻辑信道的第二PUSCH的持续时间,则指示物理层在PUCCH资源上发送SR;
例如,当前SR配置所对应的逻辑信道为逻辑信道1,且逻辑信道1配置的参数maxPUSCH-Duration为0.25个时隙,而当前与其重叠,或碰撞的UL-SCH传输数据获取的逻辑信道配置的maxPUSCH-Duration为0.5个时隙。由于0.25个时隙小于0.5个时隙,那么认为该SR配置可以优先于该UL-SCH发送,物理层发送该SR。
进一步地,在所述配置信息包括子载波间隔SCS列表信息时;
所述在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道,包括:
在第一SCS大于或者等于第二SCS时,确定第一逻辑信道为时延要求较高的逻辑信道,否则,确定第二逻辑信道为时延要求较高的逻辑信道;
其中,第一SCS为第一逻辑信道上配置的最大SCS,所述第二SCS为第二逻辑信道上配置的最大SCS。
下面结合实施例二来进行具体说明。
实施例二:上述第一传输资源为控制信息SR的传输资源,上述第二传输资源为上行共享信道资源。
步骤一:网络侧设备向终端设备发送逻辑信道的配置信息。所述配置信息中包括SCS列表信息。
举例来讲,对于逻辑信道1,其参数能够使用的SCS列表allowedSCS-List中的子载波间隔为120KHz和60KHz,表示该逻辑信道能够使用的上行授权的子载波间隔为120KHz和60KHz;对于逻辑信道2,其参数allowedSCS-List中的子载波间隔为240KHz,表示该逻辑信道能够使用的上行授权的子载波间隔为240KHz。一般认为,allowedSCS-List中SCS数值越大,则表示该逻辑信道要求的时延越短。
步骤二:所述终端设备接收网络侧设备发送的配置信息。
步骤三:当所述终端设备至少一个SR处于挂起状态时,MAC实体将针对每个挂起的SR:
参见图4,在当前挂起SR的SR配置的PUCCH资源与UL-SCH重叠时, 如果SR配置对应的第一逻辑信道的第一子载波间隔大于或者等于所述UL-SCH对应的第二逻辑信道的第二子载波间隔,则指示物理层在PUCCH资源上发送SR;
例如,当前SR配置所对应的逻辑信道为逻辑信道1,且逻辑信道1配置的参数allowedSCS-List中最大子载波间隔为120KHz,而当前与其重叠,或碰撞的UL-SCH传输数据获取的逻辑信道配置的allowedSCS-List中最大子载波间隔为60KHz。由于120大于60,那么认为该SR配置可以优先于该UL-SCH发送,物理层发送该SR。
进一步地,在所述配置信息包括配置授权信息时;
所述在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道,包括:
在第一配置授权信息为允许使用配置授权类型1,第二配置授权信息为不允许使用配置授权类型1的情况下,确定第一逻辑信道为时延要求较高的逻辑信道;
在第一配置授权信息为不允许使用配置授权类型1,第二配置授权信息为允许使用配置授权类型1的情况下,确定第二逻辑信道为时延要求较高的逻辑信道;
其中,第一配置授权信息为第一逻辑信道的配置授权信息,第二配置授权信息为第二逻辑信道的配置授权信息。
下面结合实施例三来进行具体说明。
实施例三:上述第一传输资源为控制信息SR的传输资源,上述第二传输资源为上行共享信道资源。
步骤一:网络侧设备向终端设备发送逻辑信道的配置信息。所述配置信息中包括配置授权信息。
举例来讲,对于逻辑信道1,其参数configuredGrantType1Allowed为true,表示该逻辑信道能够使用配置授权类型1;对于逻辑信道2,其参数configuredGrantType1Allowed为false,表示该逻辑信道不能够使用配置授权类型1。一般认为,使用配置授权类型1能减少数据传输时延。
步骤二:终端设备接收网络侧设备发送的配置信息。
步骤三:当所述终端设备至少一个SR处于挂起状态时,MAC实体将针对每个挂起的SR:
参见图4,在当前挂起SR的SR配置的PUCCH资源与UL-SCH重叠时,如果SR配置对应的第一逻辑信道允许使用配置授权类型1,而所述UL-SCH对应的第二逻辑信道不允许使用配置授权类型1,那么将指示物理层在PUCCH资源上发送SR;
例如,当前SR配置所对应的逻辑信道为逻辑信道1,且逻辑信道1配置的参数configuredGrantType1Allowed为true,而当前与其重叠,或碰撞的UL-SCH传输数据获取的逻辑信道配置的configuredGrantType1Allowed为false,那么认为该SR配置可以优先于该UL-SCH发送,物理层发送该SR。
进一步地,在所述配置信息包括优先级信息时;
所述在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道,包括:
在第一优先级高于或者等于第二优先级时,确定第一逻辑信道为时延要求较高的逻辑信道,否则,确定第二逻辑信道为时延要求较高的逻辑信道;
其中,第一优先级为第一逻辑信道上配置的优先级,第二优先级为第二逻辑信道上配置的优先级。
本公开实施例中,逻辑信道要求的时延越短,则逻辑信道配置的优先级越高。
例如,当前SR配置所对应的逻辑信道为逻辑信道1,且逻辑信道1配置的优先级为第一优先级,而当前与其重叠,或碰撞的UL-SCH传输数据获取的逻辑信道配置的优先级为第二优先级,且第一优先级高于第二优先级,那么认为该SR配置可以优先于该UL-SCH发送,物理层发送该SR。
进一步地,在所述配置信息包括最大物理上行共享信道PUSCH的持续时间信息、子载波间隔SCS列表信息、调制与编码策略MCS列表信息和配置授权信息时;
所述在第一逻辑信道和第二逻辑信道中确定时延要求较高的逻辑信道,包括:
判断所述配置信息是否满足预设条件;
在满足预设条件时,确定第一逻辑信道为时延要求较高的逻辑信道,否则,确定第二逻辑信道为时延要求较高的逻辑信道;
其中,所述预设条件包括以下至少一个:
第一PUSCH的持续时间小于或者等于第二PUSCH的持续时间;
第一SCS大于或者等于第二SCS;
第一配置授权信息为能够使用配置授权类型,第二配置授权信道为不能够使用配置授权类型;

其中,第一PUSCH的持续时间为第一逻辑信道上配置的最大PUSCH持续时间;第二PUSCH的持续时间为第二逻辑信道上配置的最大PUSCH的持续时间;
第一SCS为第一逻辑信道上配置的最大SCS,所述第二SCS为第二逻辑信道上配置的最大SCS;
第一配置授权信息为第一逻辑信道的配置授权信息,第二配置授权信息为第二逻辑信道的配置授权信息;

下面结合实施例四来进行具体说明。
实施例四:上述第一传输资源和第二传输资源均为上行共享信道资源。
步骤一:网络侧设备向终端设备发送逻辑信道的配置信息。所述配置信息中包括所述逻辑信道能够使用的最长的PUSCH持续时间信息,SCS列表信息,MCS表格信息和是否允许使用配置授权信息中的至少一项。
举例来讲,对于逻辑信道1,其参数最大PUSCH的持续时间maxPUSCH-Duration为0.5个时隙,表示该逻辑信道能够使用的上行授权的PUSCH持续时间最大为0.5个时隙;对于逻辑信道2,其参数maxPUSCH-Duration为0.25个时隙,表示该逻辑信道能够使用的上行授权的PUSCH持续时间最大为0.25个时隙。一般认为,maxPUSCH-Duration越短,则表示该逻辑信道要求的时延越短。
举例来讲,对于逻辑信道1,其参数能够使用的SCS列表allowedSCS-List中的子载波间隔为120KHz和60KHz,表示该逻辑信道能够使用的上行授权的子载波间隔为120KHz和60KHz;对于逻辑信道2,其参数allowedSCS-List中的子载波间隔为240KHz,表示该逻辑信道能够使用的上行授权的子载波间隔为240KHz。一般认为,allowedSCS-List中SCS数值越大,则表示该逻辑信道要求的时延越短。
举例来讲,对于逻辑信道1,其参数configuredGrantType1Allowed为true,表示该逻辑信道能够使用配置授权类型1;对于逻辑信道2,其参数configuredGrantType1Allowed为false,表示该逻辑信道不能够使用配置授权类型1。一般认为,使用配置授权类型1能减少数据传输时延。
步骤二:所述终端设备接收网络侧设备发送的配置信息。
步骤三:当所述终端设备执行数据传输时:
参见图5,如果数据传输的UL-SCH信道资源发生碰撞,当配置授权传输的PUSCH持续时间(第一PUSCH的持续时间)与PDCCH调度的PUSCH持续时间(第二PUSCH的持续时间)相重叠时,UE需要判断:
第一PUSCH所对应的第一逻辑信道上配置的最大PUSCH持续时间是否小于或者等于第二PUSCH所对应的第二逻辑信道上配置的最大PUSCH的持续时间;
和/或,第一PUSCH所对应的第一逻辑信道上配置的第一SCS的长度是否大于或者等于第二PUSCH所对应的第二逻辑信道上配置的第二SCS的长度;
和/或,第一PUSCH所对应的第一逻辑信道是否支持配置授权类型1;
和/或,第一PUSCH所对应的第一逻辑信道是否支持64QAM调度:
如果满足是,UE将在第一PUSCH的持续时间内发送数据;
否则,UE将在第二PUSCH的持续时间内发送数据。
