Description
技术领域technical field
本发明涉及移动通信技术领域,具体涉及一种触发信道状态信息上报的方法及设备。The invention relates to the technical field of mobile communication, in particular to a method and device for triggering reporting of channel state information.
背景技术Background technique
目前新空口(NR)系统支持为一个用户设备(UE)配置多个带宽部分(BWP,BandwithPart),高层信令为终端配置一组(如最多4个)下行BWP和一组(如最多4个)上行BWP。对于时分双工(TDD,Time Division Duplex)来说,一个下行BWP和一个上行BWP相关联,组成一个BWP对,并且索引相同,且上下行BWP的中心频率是相同的。对于频分双工(FDD,FrequencyDivision Duplex)来说,上下行BWP没有关联关系,中心频点不相同。终端在一个时刻只能工作在一个激活BWP上,基站可以通过无线资源控制(RRC)信令对BWP进行激活和去激活,也可以在下行控制信息(DCI,Downlink Control Information)中通过BWP指示符,指示终端在哪个激活的BWP进行数据的接收或发送。在通过DCI进行BWP的切换中,BWP指示符可以位于调度下行数据(PDSCH)的DCI format 1_1中,也可以位于调度上行数据(PUSCH)的DCIformat 0_1中。对于FDD来说,调度下行数据PDSCH的DCI format只能切换下行BWP,调度上行数据PUSCH的DCI format 0_1只能切换上行BWP。而对于TDD来说,如果调度下行数据PDSCH的DCI format 1_1中BWP指示符指示的一个新的下行BWP,那么上行BWP也需要切换到具有相同索引的通过BWP指示符指示的新的上行BWP上。同理,如果调度上行数据PUSCH的DCI format 0_1中进行上行BWP切换,则下行BWP也需要切换到具有相同索引的新的下行BWP上。At present, the new air interface (NR) system supports configuring multiple bandwidth parts (BWP, BandwithPart) for a user equipment (UE). ) uplink BWP. For Time Division Duplex (TDD, Time Division Duplex), a downlink BWP is associated with an uplink BWP to form a BWP pair, and the indexes are the same, and the center frequencies of the uplink and downlink BWPs are the same. For Frequency Division Duplex (FDD, Frequency Division Duplex), the uplink and downlink BWPs are not related, and the center frequency points are different. The terminal can only work on one active BWP at a time, and the base station can activate and deactivate the BWP through the radio resource control (RRC) signaling, or through the BWP indicator in the downlink control information (DCI, Downlink Control Information) , indicating which activated BWP the terminal uses to receive or send data. In BWP switching through DCI, the BWP indicator can be located in DCI format 1_1 for scheduling downlink data (PDSCH), or in DCI format 0_1 for scheduling uplink data (PUSCH). For FDD, the DCI format for scheduling the downlink data PDSCH can only switch the downlink BWP, and the DCI format 0_1 for scheduling the uplink data PUSCH can only switch the uplink BWP. For TDD, if a new downlink BWP indicated by the BWP indicator in DCI format 1_1 of the downlink data PDSCH is scheduled, then the uplink BWP also needs to be switched to the new uplink BWP indicated by the BWP indicator with the same index. Similarly, if the uplink BWP switching is performed in the DCI format 0_1 of the uplink data PUSCH, the downlink BWP also needs to be switched to a new downlink BWP with the same index.

目前,信道状态信息(CSI,Channel State Information)的测量和上报只能发生在激活BWP上,不能发生在未激活的BWP上。在调度上行数据(PUSCH)的DCI format 0_1中携带“CSI请求”信息域,可以触发终端在上行BWP上通过PUSCH进行非周期的CSI上报。Currently, the measurement and reporting of Channel State Information (CSI, Channel State Information) can only occur on the active BWP, and cannot occur on the inactive BWP. Carrying the "CSI request" information field in the DCI format 0_1 of scheduling uplink data (PUSCH) can trigger the terminal to perform aperiodic CSI reporting through the PUSCH on the uplink BWP.
NR系统目前只支持在激活BWP的CSI的测量上报,因此,在切换到新的BWP之后,才可以进行CSI的测量上报。如果是周期性的CSI上报,必须等到周期的测量上报时间;而如果是非周期性的CSI上报,终端需要先收到一个携带“CSI请求”的DCI,才能进行CSI的测量和上报。因此,在切换到新的BWP的起始一段时间内,终端是无法进行快速的CSI测量和上报的。另一方面,由于目前NR仅支持在激活BWP上的测量上报,如果基站只希望获得某个BWP的CSI信息,必须先通过DCI将终端切换到目标BWP上,当CSI测量上报完成后,再将终端通过DCI切换回到原先的BWP。Currently, the NR system only supports CSI measurement reporting when the BWP is activated. Therefore, CSI measurement reporting can only be performed after switching to a new BWP. If it is periodic CSI reporting, it must wait until the periodic measurement reporting time; and if it is aperiodic CSI reporting, the terminal needs to receive a DCI carrying a "CSI request" before performing CSI measurement and reporting. Therefore, during the initial period of switching to the new BWP, the terminal cannot perform fast CSI measurement and reporting. On the other hand, since NR currently only supports measurement reporting on the active BWP, if the base station only wants to obtain the CSI information of a certain BWP, it must first switch the terminal to the target BWP through DCI. The terminal switches back to the original BWP through DCI.
按照目前的BWP切换流程和触发非周期的CSI上报流程,假设终端当前工作在DLBWP#1,基站希望获得DL BWP#2的信道状态信息,并且在获取完信道状态信息后切换回到DLBWP#1,则针对TDD和FDD,目前触发CSI上报的流程如下:According to the current BWP switching process and triggering aperiodic CSI reporting process, assuming that the terminal is currently working in DLBWP#1, the base station hopes to obtain the channel state information of DL BWP#2, and switch back to DLBWP#1 after obtaining the channel state information , for TDD and FDD, the current process of triggering CSI reporting is as follows:
TDD:TDD:
1)基站在DL BWP#1上传输调度PDSCH的DCI format 1_1,指示终端由DL BWP#1切换到DL BWP#2,由于TDD情况下,DL BWP和UL BWP存在绑定关系,终端在切换DL BWP的同时,也会将UL BWP切换到UL BWP#2。1) The base station transmits the DCI format 1_1 for scheduling PDSCH on DL BWP#1, and instructs the terminal to switch from DL BWP#1 to DL BWP#2. Since there is a binding relationship between DL BWP and UL BWP in the case of TDD, the terminal is switching DL At the same time of BWP, UL BWP will also be switched to UL BWP#2.
2)基站在DL BWP#2上传输调度PUSCH的DCI format 0_1,触发终端的CSI请求,终端在DL BWP#2上进行CSI测量,并在UL BWP#2上进行上报。2) The base station transmits the DCI format 0_1 for scheduling PUSCH on DL BWP#2, triggers the CSI request of the terminal, and the terminal performs CSI measurement on DL BWP#2, and reports on UL BWP#2.
3)基站在DL BWP#2上传输调度PUSCH的DCI format 0_1或调度PDSCH的DCIformat 1_1,指示终端从UL BWP#2和DL BWP#2切换回UL BWP#1和DL BWP#1。3) The base station transmits DCI format 0_1 for scheduling PUSCH or DCI format 1_1 for scheduling PDSCH on DL BWP#2, and instructs the terminal to switch back from UL BWP#2 and DL BWP#2 to UL BWP#1 and DL BWP#1.
FDD:FDD:
1)基站在DL BWP#1上传输调度PDSCH的DCI format 1_1,指示终端DL BWP#1切换到DL BWP#2。1) The base station transmits DCI format 1_1 for scheduling PDSCH on DL BWP#1, and instructs the terminal to switch from DL BWP#1 to DL BWP#2.
2)基站在DL BWP#2上传输调度PUSCH的DCI format 0_1,触发终端的CSI请求,终端在DL BWP#2上进行CSI测量,并在某个UL BWP上进行上报。2) The base station transmits the DCI format 0_1 for scheduling PUSCH on DL BWP#2, triggers the CSI request of the terminal, and the terminal performs CSI measurement on DL BWP#2, and reports it on a certain UL BWP.
3)基站在DL BWP#2上传输调度PDSCH的DCI format 1_1,指示终端从DL BWP#2切换回到DL BWP#1。3) The base station transmits the DCI format 1_1 of scheduling PDSCH on DL BWP#2, and instructs the terminal to switch from DL BWP#2 back to DL BWP#1.
参考图1可以看出,如果基站想获取某个BWP的信道状态信息,同时需要在获取信道状态信息之后切换回到当前的BWP,那么需要3个PDCCH才能够完成。终端需要接收3个PDCCH才能完成其他非激活BWP的CSI的测量上报工作,导致时延较大,同时由于终端在BWP切换过程中不能进行数据收发,因此降低了频谱利用效率。如果基站需要频繁的获取其他非激活BWP的信道状态信息,则网络侧的PDCCH信令开销也比较大。Referring to FIG. 1, it can be seen that if the base station wants to obtain channel state information of a certain BWP, and needs to switch back to the current BWP after obtaining the channel state information, then three PDCCHs are required to complete. The terminal needs to receive 3 PDCCHs to complete the CSI measurement and reporting work of other inactive BWPs, resulting in a large delay. At the same time, because the terminal cannot transmit and receive data during the BWP switching process, the spectrum utilization efficiency is reduced. If the base station needs to frequently acquire channel state information of other inactive BWPs, the PDCCH signaling overhead on the network side is relatively large.
为解决以上问题中的至少一个,本发明至少一个实施例提供了一种触发信道状态信息上报的方法,利用PDCCH触发终端在其他BWP进行信道状态测量上报,减小以上流程中需要3个PDCCH的交互过程导致的时延,降低整体流程的时延和控制信令开销。In order to solve at least one of the above problems, at least one embodiment of the present invention provides a method for triggering channel state information reporting, using the PDCCH to trigger the terminal to perform channel state measurement reporting in other BWPs, reducing the need for three PDCCHs in the above process. The delay caused by the interactive process reduces the overall process delay and control signaling overhead.

需要说明的是,本发明实施例的网络设备可以由图2中的基站(接入网节点),还可以由核心网节点,或者是由接入网节点与核心网节点共同实现。It should be noted that the network device in the embodiment of the present invention may be implemented by the base station (access network node) in FIG. 2 , or by a core network node, or jointly implemented by an access network node and a core network node.
请参照图3,本发明实施例提供的一种触发信道状态信息上报的方法,应用于基站侧,包括:Please refer to Figure 3, a method for triggering channel state information reporting provided by an embodiment of the present invention is applied to the base station side, including:
步骤31,向终端发送用于调度物理上行共享信道(PUSCH)的下行控制信息,所述下行控制信息包括有第一信息域和第二信息域。Step 31: Send downlink control information for scheduling a physical uplink shared channel (PUSCH) to the terminal, where the downlink control information includes a first information field and a second information field.
其中,所述第一信息域用于指示所述第一下行BWP,第一下行BWP为激活下行BWP或所述终端进行信道状态信息(CSI)测量的下行BWP或所述终端进行CSI上报所关联的下行BWP;所述第二信息域用于指示第一上行BWP,所述第一上行BWP是激活上行BWP或所述终端传输PUSCH进行CSI上报的上行BWP。Wherein, the first information field is used to indicate the first downlink BWP, and the first downlink BWP is the downlink BWP that activates the downlink BWP or the terminal performs channel state information (CSI) measurement or the terminal performs CSI reporting The associated downlink BWP; the second information field is used to indicate the first uplink BWP, and the first uplink BWP is the uplink BWP activated or the terminal transmits the PUSCH to report the CSI.
这里,上述下行控制信息(DCI)可以携带一个PDCCH中,从以上步骤可以看出,本发明实施例在DCI中新增了第一、第二信息域,从而通过一个PDCCH(一个DCI)分别指示了第一下行BWP和第一上行BWP。Here, the above-mentioned downlink control information (DCI) can be carried in one PDCCH. It can be seen from the above steps that the embodiment of the present invention adds a first and a second information field to the DCI, so that a PDCCH (one DCI) respectively indicates The first downlink BWP and the first uplink BWP are selected.
其中,所述第一下行BWP可以是激活下行BWP,这样终端在收到上述DCI之后,需要将所述终端当前的激活第二下行BWP切换为所述第一下行BWP,然后在第一下行BWP上进行CSI测量。当然,如果所述激活第二下行BWP与所述第一下行BWP是同一BWP,则不需要进行上述BWP的切换。Wherein, the first downlink BWP may be an activated downlink BWP, so that after receiving the DCI, the terminal needs to switch the current activated second downlink BWP of the terminal to the first downlink BWP, and then CSI measurement is performed on the downlink BWP. Of course, if the activated second downlink BWP is the same BWP as the first downlink BWP, the above BWP switching does not need to be performed.
所述第一下行BWP还可以是所述终端进行信道状态信息(CSI)测量的下行BWP,这样终端收到上述DCI之后,可以在第一下行BWP上进行CSI测量。当然,如果终端激活下行BWP和所述第一下行BWP不是同一BWP,则在CSI测量前还需要将所述终端当前的激活下行BWP切换为所述第一下行BWP。The first downlink BWP may also be a downlink BWP on which the terminal performs channel state information (CSI) measurement, so that the terminal may perform CSI measurement on the first downlink BWP after receiving the DCI. Of course, if the active downlink BWP of the terminal is not the same BWP as the first downlink BWP, the current active downlink BWP of the terminal needs to be switched to the first downlink BWP before CSI measurement.
类似的,所述第一下行BWP还可以是所述终端进行CSI上报所关联的下行BWP,这里,CSI上报所关联的下行BWP是指CSI上报的信息是该下行BWP上测量得到的。Similarly, the first downlink BWP may also be the downlink BWP associated with the terminal's CSI report. Here, the downlink BWP associated with the CSI report means that the information reported by the CSI is measured on the downlink BWP.
所述第一上行BWP可以是激活上行BWP,这样终端在收到上述DCI之后,需要将所述终端当前的激活第二上行BWP切换为所述第一上行BWP,然后在第一上行BWP上进行CSI上报。当然,如果所述激活第二上行BWP与所述第一上行BWP是同一BWP,则不需要进行上述BWP的切换。类似的,所述第一上行BWP还可以所述终端传输PUSCH进行CSI上报的上行BWP。The first uplink BWP may be an activated uplink BWP. In this way, after receiving the above DCI, the terminal needs to switch the current activated second uplink BWP of the terminal to the first uplink BWP, and then proceed on the first uplink BWP. CSI reporting. Of course, if the activated second uplink BWP is the same BWP as the first uplink BWP, the above BWP switching does not need to be performed.

示例1:Example 1:
以TDD为例,终端当前的激活BWP分别为下行BWP#1和上行BWP#1。基站发送一个调度PUSCH的PDCCH,其中DCI format中的第一信息域指示终端需要进行CSI测量的下行BWP是下行BWP#2,第二信息域指示的CSI上报所在的上行BWP是上行BWP#1,第三信息域指示了某个CSI触发状态。Taking TDD as an example, the current activated BWPs of the terminal are downlink BWP#1 and uplink BWP#1 respectively. The base station sends a PDCCH that schedules the PUSCH, where the first information field in the DCI format indicates that the downlink BWP that the terminal needs to perform CSI measurement is the downlink BWP#2, and the uplink BWP where the CSI report indicated by the second information field is the uplink BWP#1, The third information field indicates a certain CSI triggering state.
如图5所示,终端在接收到该PDCCH之后,首先将下行BWP切换到下行BWP#2,上行BWP切换到上行BWP#2,然后在下行BWP#2上接收CSI的测量信号,之后,再分别切换回到下行BWP#1和上行BWP#1,在上行BWP#1的PUSCH上进行CSI的上报。As shown in Figure 5, after receiving the PDCCH, the terminal first switches the downlink BWP to downlink BWP#2, switches the uplink BWP to uplink BWP#2, and then receives the CSI measurement signal on the downlink BWP#2, and then Switch back to downlink BWP#1 and uplink BWP#1 respectively, and report CSI on the PUSCH of uplink BWP#1.

The base station sends a PDCCH that schedules the PUSCH, where the first information field in the DCI format indicates that the downlink BWP that the terminal needs to perform CSI measurement is the downlink BWP#2, and the uplink BWP where the CSI report indicated by the second information field is the uplink BWP#2, The third information field indicates a certain CSI triggering state.

The base station sends a PDCCH that schedules the PUSCH, where the first information field in the DCI format indicates that the downlink BWP that the terminal needs to perform CSI measurement is the downlink BWP#2, and the uplink BWP where the CSI report indicated by the second information field is the uplink BWP#2, The third information field indicates a certain CSI triggering state.
如图7所示,终端在接收到该PDCCH之后,首先将下行BWP切换到下行BWP#2,上行BWP切换到上行BWP#2,然后在下行BWP#2上接收CSI的测量信号,之后,终端的下行激活BWP切换回到下行BWP#1,上行激活BWP一直为上行BWP#2,并在上行BWP#2的PUSCH上进行CSI上报。As shown in Figure 7, after receiving the PDCCH, the terminal first switches the downlink BWP to downlink BWP#2, switches the uplink BWP to uplink BWP#2, and then receives the CSI measurement signal on the downlink BWP#2, after that, the terminal The downlink active BWP switches back to downlink BWP#1, and the uplink active BWP is always uplink BWP#2, and the CSI is reported on the PUSCH of the uplink BWP#2.
与传统的流程相比,只需要一个PDCCH信令触发即可,降低了网络侧开销,终端检测的开销以及整个流程的时延。Compared with the traditional process, only one PDCCH signaling trigger is required, which reduces the overhead of the network side, the overhead of terminal detection and the delay of the whole process.
