此外,由于相关技术中网络侧设备在向终端设备发送NZP-CSI-RS资源之前,也会通过高层信令向终端设备发送该NZP-CSI-RS资源对应的配置信息(上述对应于NZP-CSI-RS资源的第二目标配置信息),因此,在本公开实施例中,将NZP-CSI-RS资源作为PRS资源时,相比于相关技术,仅增加了发送第一目标配置信息的高层信令,可以有效减少PRS配置过程中的高层信令开销。In addition, in the related art, before the network-side device sends the NZP-CSI-RS resource to the terminal device, it also sends the configuration information corresponding to the NZP-CSI-RS resource to the terminal device through high-level signaling (the above corresponds to NZP-CSI -The second target configuration information of the RS resource), therefore, in the embodiment of the present disclosure, when the NZP-CSI-RS resource is used as the PRS resource, compared to the related art, only the high-level information for sending the first target configuration information is added.

Therefore, the network-side device can configure positioning performance indicators for the terminal device through high-level signaling for specific application scenarios, and then determine a target PRS resource mapping pattern that matches the positioning performance indicator according to the positioning performance indicator, so that the target PRS can be determined according to the target PRS The resource mapping pattern sends one or more PRS resource sets to the terminal device, thereby satisfying the positioning requirements of the terminal device.

当定位时延指标较高时,即要求定位计算过程的时延要小,选择占用OFDM符号较少的第二PRS资源映射图样作为发送PRS资源集的目标PRS资源映射图样;当定位时延指标较低时,选择占用OFDM符号较多的第二PRS资源映射图样作为发送PRS资源集的目标PRS资源映射图样。When the positioning delay index is high, that is, the delay in the positioning calculation process is required to be small, and the second PRS resource mapping pattern that occupies less OFDM symbols is selected as the target PRS resource mapping pattern of the sending PRS resource set; when the positioning delay index is When it is lower, the second PRS resource mapping pattern that occupies more OFDM symbols is selected as the target PRS resource mapping pattern for sending the PRS resource set.
图6为本公开实施例提供的第二PRS资源映射图样的示意图。FIG. 6 is a schematic diagram of a second PRS resource mapping pattern provided by an embodiment of the present disclosure.
如图6所示,当定位时延指标较高时,选择符合定位时延指标的:占用3个OFDM符号的第二PRS资源映射图样作为发送PRS资源集的目标PRS资源映射图样,以减少时延。As shown in FIG. 6, when the positioning delay index is high, the one that meets the positioning delay index is selected: the second PRS resource mapping pattern occupying 3 OFDM symbols is used as the target PRS resource mapping pattern to send the PRS resource set to reduce the time Delay.
图7为本公开实施例提供的第二PRS资源映射图样的另一示意图。FIG. 7 is another schematic diagram of a second PRS resource mapping pattern according to an embodiment of the present disclosure.
如图7所示,当定位时延指标非常高时,选择符合定位时延指标的:占用1个OFDM符号的第二PRS资源映射图样作为发送PRS资源集的目标PRS资源映射图样,以减少时延。As shown in FIG. 7, when the positioning delay index is very high, the one that meets the positioning delay index is selected: the second PRS resource mapping pattern occupying 1 OFDM symbol is used as the target PRS resource mapping pattern to send the PRS resource set to reduce the time Delay.
本公开实施例中,在一个时隙内,目标PRS资源映射图样为对角线型或反对角线型。In the embodiment of the present disclosure, within one slot, the target PRS resource mapping pattern is diagonal or anti-diagonal.

其中,N不小于预设值,该预设值可以由终端设备上报网络侧设备或由网络侧设备配置。Among them, N is not less than a preset value, and the preset value may be reported by the terminal device to the network-side device or configured by the network-side device.
相比于LTE中,PRS资源映射图样需要在固定的OFDM符号上避开公共参考信号(Common Reference Signal,CRS)来说,在NR***中不存在CRS,因此,本公开实施例中的PRS资源映射图样不需要考虑避开CRS的问题。Compared with LTE, the PRS resource mapping pattern needs to avoid common reference signals (Common Reference Signals, CRS) on fixed OFDM symbols. There is no CRS in the NR system. Therefore, the PRS resources in the embodiments of the present disclosure The mapping pattern does not need to consider the problem of avoiding CRS.
此外,在LTE中PRS资源映射图样是在子帧上分布的,而子帧包含2个时隙,使得完整的PRS资源映射图样对应于相邻两个时隙内的PRS资源。在NR***中,不存在子帧的概念,因此,本公开实施例中的PRS资源映射图样仅对应于一个时隙内的PRS资源。In addition, in LTE, the PRS resource mapping pattern is distributed on a subframe, and the subframe includes 2 time slots, so that the complete PRS resource mapping pattern corresponds to PRS resources in two adjacent time slots. In the NR system, the concept of a subframe does not exist. Therefore, the PRS resource mapping pattern in the embodiment of the present disclosure only corresponds to the PRS resources in one time slot.
需要说明的是,本公开实施例所涉及的定位参考信号配置方法除了可以应用于NR***之外,还可以应用于其他未明确如何配置定位参考信号的通信***,这里不做具体限定。It should be noted that, in addition to the NR system, the positioning reference signal configuration method according to the embodiment of the present disclosure can also be applied to other communication systems for which it is not clear how to configure the positioning reference signal, which is not specifically limited herein.
