- Typical eMBB services include: ultra-high-definition video, augmented reality (AR), virtual reality (virtual reality, VR), etc.
- the main characteristics of these services are large data transmission volume and high transmission rate.
- Typical URLLC businesses include wireless control in industrial manufacturing or production processes, motion control of unmanned vehicles and drones, and tactile interaction applications such as remote repairs and remote surgery.
- the main feature of these services is that they require ultra-high reliability. With high performance, low latency, less data transmission and bursty.
- Typical mMTC services include: smart grid distribution automation, smart cities, etc.
- the main features are the huge number of networked devices, the small amount of transmitted data, and the data insensitive to transmission delay. These services need to meet low cost and very long standby time. Demand.
- the resources include, but are not limited to: time-domain symbols, frequency-domain resources, time-frequency resources, codeword resources, beam resources, and so on.
- the resource allocation of the communication system is completed by the base station, and the base station is taken as an example for description below. If the base station allocates resources for URLLC service data by reserving resources, system resources are wasted when there is no URLLC service data.
- the short delay characteristic of the URLLC service requires that the data packet be transmitted in a very short time, so the base station needs to reserve a large enough bandwidth for the URLLC service data, which leads to a serious decline in system resource utilization.
- a longer time scheduling unit is usually used for data transmission to improve transmission efficiency.
- a time slot with a 15kHz subcarrier interval corresponds to 14 time domains.
- the corresponding time length is 1 millisecond (millisecond, ms).
- URLLC service data usually uses a shorter time scheduling unit to meet the needs of ultra-short delay. For example, using 2 time domain symbols with 15 kilohertz (kilohertz, kHz) subcarrier spacing, the corresponding time length is 0.14 ms, Or one time slot with a 60kHz subcarrier interval is used, corresponding to 14 time domain symbols, and the corresponding time length is 0.25ms.
- the base station Due to the burstiness of URLLC service data, in order to improve the utilization of system resources, the base station usually does not reserve resources for the downlink data transmission of the URLLC service.
- URLLC service data arrives at the base station, if there is no free time-frequency resource at this time, in order to meet the ultra-short delay requirement of the URLLC service, the base station cannot wait for the completion of this scheduled eMBB service data transmission before scheduling the URLLC service data. .
- the base station can adopt a preemptive way to allocate resources for URLLC service data. As shown in Figure 1, the preemption here means that the base station selects part or all of the time-frequency resources for transmitting URLLC service data from the time-frequency resources that have been allocated for transmitting eMBB service data. Of course, the base station does not send eMBB service data on the time-frequency resources used to transmit URLLC service data.
- time-domain symbols in the embodiments of the present application may also be referred to as symbols for short.
- the symbols may be, for example, a long term evolution (LTE) system or an orthogonal frequency division multiplexing in an NR system.
- OFDM orthogonal frequency division multiplexing
- DFT-s-OFDM discrete Fourier transform-spread-OFDM
- the symbols in the embodiments of the present application refer to time-domain symbols.
- the eMBB service data resource may be preempted by the burst URLLC service data resource. If the terminal device receiving the eMBB service data does not know that its data resource is preempted, it may use the URLLC service data as its own data for demodulation and decoding. , Resulting in decoding failure. What's more serious is that, for the transmission block that fails to decode, the terminal device will store the soft value interfered by URLLC, and perform the soft-value combination decoding with the retransmitted data, resulting in decoding errors during retransmission. To solve this problem, the NR system introduced PI.
- the PI is carried in public downlink control information (downlink control information, DCI), and is characterized by a 14-bit bitmap.
- the transmission period of the DCI carrying PI is configured by high-level parameters, with a slot as a unit. Assuming that the transmission period of the DCI carrying PI is T INT time slots, the time-frequency range indicated by each 14-bit PI is:
- Time domain recorded as N INT time domain symbols.
- the N INT time domain symbols are the ones before the first time domain symbol of the physical downlink control channel (physical downlink control channel, PDCCH) corresponding to the DCI carrying PI Time domain symbols.
- T INT is the cycle of detecting PI configured by the upper layer, Is the number of symbols per time slot, ⁇ INT is the subcarrier interval index corresponding to the BWP of the terminal device receiving DCI, and ⁇ is the subcarrier interval index corresponding to the activated BWP on the serving cell to which this PI is applied.
- the value of N INT is equal to Subtract the number of UL time domain symbols indicated in the high-level signaling TDD-UL-DL-configuration common or TDD-UL-DL-configuration common.
- the frequency domain range indicated by PI is the entire BWP
- the N INT time domain symbols indicated by PI are 28 time domain symbols.
- the frequency domain range indicated by PI is the entire BWP
- the N INT time domain symbols indicated by PI are 18 time domain symbols.
- the time-frequency resources corresponding to the PI can be divided in two ways, and the time-frequency sub-resources corresponding to each bit in the 14 bits are also different.
- the time-frequency block is divided into 14 parts in time, and no division in frequency, corresponding to ⁇ 14, 1 ⁇ .
- 14-bit PI each bit corresponds to a time-frequency sub-resource.
- the time-frequency block is divided into 7 parts in time and 2 parts in frequency, corresponding to ⁇ 7, 2 ⁇ .
- the 14-bit PI is divided into one group for every 2bit, a total of seven groups.
- a bit of 0 in the bitmap indicates that the user's transmission may be available on the time-frequency resource (it can also be understood as not being preempted by the URLLC data resource); a bit of 1 indicates that there is no transmission of the user on the time-frequency resource.
- rate matching resources some resources that cannot be used to transmit PDSCH are defined, called rate matching resources. This part of the resources can be used for forward or backward compatibility of the NR system. For example, some resources are periodically allocated in the NR resource for use by a certain system or a certain function in the future. If these resources have an intersection with the PDSCH time-frequency resource blocks confirmed according to the DCI, the intersection resources are not used to transmit the PDSCH.
- the resources defined by the NR system that cannot be used to transmit PDSCH are divided into three categories, including: RB symbol-level resources, resource element (resource element, RE)-level resources, and synchronization signal (SS)/physical broadcast channels (physical broadcast channel, PBCH) block (SS/PBCH block, SSB) resource.

- SS synchronization signal
- PBCH physical broadcast channel

- a rate matching pattern can include:
- the pair of reserved resources includes an RB-level bitmap and a symbol-level bitmap with a length of 2 slots. Among them, if the bit value of the RB-level bitmap and the symbol-level bitmap is 1, it means that the corresponding resource cannot be used to transmit the PDSCH.
- a period and pattern (periodicity and pattern) can be configured, and each bit in the periodicality and pattern corresponds to a symbol-level bitmap. Among them, if the bit value in the periodicity and pattern is 1, it means that there is a reserved resource pair for this unit.
- the RB-level bitmap is 00110...11
- the symbol-level bitmap is 10...11 01...10
- a time unit containing 12 OFDM symbols or 14 OFDM symbols is called a subframe in the LTE system, and corresponds to 2 slots; in the NR system, it corresponds to 1 slot.
- the slots in the following embodiments of the present application are described by taking the slots of the NR system as an example.

- the code length in the frequency domain is 2 and the code length in the time domain is 4.
- N antenna ports will perform CDM transmission on N REs. Each antenna port corresponds to one CDM N orthogonal code. After the corresponding CSI-RS signal is multiplied by the orthogonal code, N signals are obtained and transmitted on N REs. In other words, the signal transmitted on each RE is a signal superposition of the CSI-RS signals of N antenna ports after orthogonal code processing. At the receiving end, the signals on the N REs must be completely received to process the N CSI-RSs corresponding to the N antenna ports.

Description
本申请涉及无线通信技术领域,尤其涉及测量方法、装置及***。
第五代(the fifth generation,5G)移动通信***中的新无线(new radio,NR)***中,定义了一些不能用来发送物理下行共享信道(physical downlink shared channel,PDSCH)的资源,称为速率匹配资源。这部分资源可以用来进行NR***的前向和后向兼容,例如在NR资源中周期的划出部分资源给未来的某个***或某个功能使用。此外,国际电信联盟(international telecommunication union,ITU)为NR***以及未来的移动通信***定义了三大类应用场景,包括:增强移动宽带(enhanced mobile broadband,eMBB)、高可靠低时延通信(ultra-reliable and low latency communications,URLLC)以及海量机器类通信(massive machine type communications,mMTC)。其中,URLLC业务的主要特点是要求超高可靠性、低延时,传输数据量较少以及具有突发性。
由于速率匹配资源是为了前向和后向兼容,URLLC业务要求超高可靠性、低延时,因此他们的优先级可能比较高,进而若速率匹配资源或者承载URLLC业务数据的PDSCH资源与测量资源重叠,则测量资源受到干扰的影响会比较大。在本申请中,测量资源例如可以是非零功率(non-zero power,NZP)信道状态信息(channel state information,CSI)-参考信号(reference signal,RS)资源或者CSI-干扰测量(interference measurement,IM)资源。
比如,若一个终端设备的NZP CSI-RS资源与承载其他终端设备的URLLC业务数据的PDSCH资源重叠,则该NZP CSI-RS资源上的NZP CSI-RS和该PDSCH资源上的URLLC业务数据会互相干扰。若一个终端设备的CSI-IM资源与承载其他终端设备的URLLC业务数据的PDSCH资源重叠,则在CSI-IM资源上进行干扰测量会受到该PDSCH资源上URLLC业务数据的干扰,从而影响终端设备的干扰测量的准确性。在本申请中,两个资源重叠可以为部分重叠或完全重叠。
或者,比如,若一个终端设备的NZP CSI-RS资源与速率匹配资源重叠,则该NZP CSI-RS资源上的NZP CSI-RS和速率匹配资源上的用于前向或后向兼容的信号会互相干扰;若一个终端设备的CSI-IM资源与速率匹配资源重叠,则在CSI-IM资源上进行干扰测量会受到速率匹配资源上用于前向或后向兼容的信号的干扰,从而影响终端设备的干扰测量的准确性。
为解决上述问题,可以在基站调度时保证NZP CSI-RS资源/CSI-IM资源和速率匹配资源/承载URLLC业务数据的PDSCH资源不重叠。然而,NZP CSI-RS资源和CSI-IM资源可能是周期或者半持续(semi-persistent,SP)的,URLLC业务数据的调度是相对随机的,速率匹配资源需要基于前向和后向兼容的应用场景进行灵活配置。因此要保证NZP CSI-RS资源/CSI-IM资源和速率匹配资源/承载URLLC业务数据的PDSCH资源不重叠,可能会增大调度复杂度,降低调度灵活性。
发明内容
本申请实施例提供测量方法、装置及***,可以避免测量资源上其他信号干扰,提升测量性能。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,提供了一种测量方法,执行该方法的通信装置可以为终端设备也可以为应用于终端设备中的模块,例如芯片。下面以执行主体为终端设备为例进行描述。终端设备接收来自网络设备的第一信息和第二信息,并根据第一信息确定第一资源,根据第二信息确定第二资源。进一步的,终端设备根据第一资源和第二资源确定第三资源,该第三资源包括第一资源中除第一重叠资源之外的部分或全部资源,第一重叠资源为第一资源和第二资源的重叠资源。最后,终端设备在第三资源上进行测量。基于本申请实施例提供的测量方法,可以在第一资源中除第一重叠资源之外的部分或全部资源上进行测量。也就是说,在第一资源和第二资源的重叠资源上,或者在第一资源和第二资源的重叠资源以及重叠资源的相关资源上,不进行测量,因此可以避免因为测量资源上其他信号的干扰,造成的测量性能下降的问题。
在一种可能的设计中,第二信息为速率匹配资源的配置信息,第二资源为速率匹配资源;或者,第二信息为抢占指示PI,该第二资源为该PI所指示的抢占资源。
在一种可能的设计中,第三资源为第一资源中与第四资源不重叠的资源,第四资源包括第一资源中第一时域符号上的第一频域范围内的资源,第一时域符号为第一重叠资源对应的时域资源中的一个时域符号,第一频域范围包括第二重叠资源所在的频域范围,第二重叠资源为第一重叠资源中第一时域符号上的重叠资源。
在一种可能的设计中,第四资源还包括第一资源中第二时域符号上的第一频域范围内的资源,该第二时域符号为与第二重叠资源有时域码分多址CDM关系的时域符号。也就是说,考虑到码分复用资源,若N个RE中的每个RE上传输的测量信号是N个天线端口的测量信号经过正交码处理后的信号叠加,则在接收端,必须完整的收到这N个RE上的测量信号,才能处理得到N个天线端口对应的测量信号。因此,若第四资源包括第一资源中第一时域符号上的第一频域范围内的资源,则第四资源还可以包括第一资源中第二时域符号上的第一频域范围内的资源,该第二时域符号为与第二重叠资源有时域码分多址CDM关系的时域符号。由于第二时域符号为与第二重叠资源有时域码分多址CDM关系的时域符号,即第一资源中第二时域符号上的第一频域范围内的资源与第一资源中第一时域符号上的第一频域范围内的资源有时域CDM关系,因此第一资源中第一时域符号上的第一频域范围内的资源和第一资源中第二时域符号上的第一频域范围内的资源上承载的测量信号通过CDM映射到多个天线端口,当第一资源中第一时域符号上的第一频域范围内的资源上承载的测量信号被打孔打掉了,那么第一资源中第二时域符号上的第一频域范围内的资源上承载的测量信号也无法正确解调。基于该方案,由于第四资源还包括第一资源中第二时域符号上的第一频域范围内的资源,因此可以避免接收侧无法正确解调完整的测量信号的问题,从而可以提升测量性能。
在一种可能的设计中,当该测量为宽带测量时,第一频域范围为第一资源对应的频域范围;或者,当进行的测量为子带测量时,第一频域范围为第二重叠资源所在的子 带对应的频域范围。
在一种可能的设计中,第一资源的时域资源不晚于信道状态信息CSI报告对应的CSI参考资源的时域位置,当第二资源为PI所指示的抢占资源时,该CSI参考资源的时域位置为下行时隙n-N-K,
μ
DL和μ
UL分别是下行子载波间隔SCS的索引和上行SCS的索引,N是根据第一信息中的参数确定的,N和K均为非负整数,n'为发送该CSI报告的时隙索引。也就是说,考虑到当第二资源为PI所指示的抢占资源时,PI所指示的抢占资源可以通过承载PI的DCI获知,而一个CSI报告对应一个CSI参考资源,这个CSI报告使用的测量资源不晚于这个CSI参考资源。这样可能造成在时域位置不晚于现有的CSI参考资源的时域位置的资源上,本来应该开始进行测量,但是需要等PI解析完毕,获知第一资源和第二资源的重叠资源的情况下,才开始真正的测量,从而导致基于不晚于现有的CSI参考资源的时域位置的资源获得的CSI报告来不及在相应的上行时隙n'上发送的问题。基于此,本申请实施例中,定义CSI参考资源的时域位置为下行时隙n-N-K,相对于现有的CSI参考资源的时域位置下行时隙n-N,提前了K个时隙,因此可以使得基于不晚于现有的CSI参考资源的时域位置的资源获得的CSI报告能够及时在相应的上行时隙n'上发送。
在一种可能的设计中,终端设备接收来自网络设备的第三信息,该第三信息指示K的取值;或者,终端设备根据物理下行控制信道的处理时间和/或该PI的时域周期,确定K的取值。也就是说,本申请实施例中,K的取值可以是由终端设备根据相关参数和预定的规则确定的,也可以是由网络设备确定后发送给终端设备的。
第二方面,提供了一种测量方法,执行该方法的通信装置可以为网络设备也可以为应用于网络设备中的模块,例如芯片。下面以执行主体为网络设备为例进行描述。网络设备发送第一信息和第二信息,该第一信息指示第一资源,该第二信息指示第二资源。网络设备根据第一资源和第二资源确定第三资源,该第三资源包括第一资源中除第一重叠资源之外的部分或全部资源,其中,该第一重叠资源为第一资源和第二资源的重叠资源。最后,网络设备在第三资源上发送测量信号,或者,网络设备确定不在第三资源发送信号。由于该方法是与第一方面提供的测量方法相对应的网络侧的方法,因此也能实现第一方面提供的测量方法所能实现的有益效果。
在一种可能的设计中,第二信息为速率匹配资源的配置信息,第二资源为速率匹配资源;或者,第二信息为抢占指示PI,该第二资源为该PI所指示的抢占资源。
在一种可能的设计中,第三资源为第一资源中与第四资源不重叠的资源,第四资源包括第一资源中第一时域符号上的第一频域范围内的资源,第一时域符号为第一重叠资源对应的时域资源中的一个时域符号,第一频域范围包括第二重叠资源所在的频域范围,第二重叠资源为第一重叠资源中第一时域符号上的重叠资源。
在一种可能的设计中,第四资源还包括第一资源中第二时域符号上的第一频域范围内的资源,该第二时域符号为与第二重叠资源有时域码分多址CDM关系的时域符号。
在一种可能的设计中,当该测量为宽带测量时,第一频域范围为第一资源对应的频域范围;或者,当进行的测量为子带测量时,第一频域范围为第二重叠资源所在的子带对应的频域范围。
在一种可能的设计中,第一资源的时域资源不晚于信道状态信息CSI报告对应的 CSI参考资源的时域位置,当第二资源为PI所指示的抢占资源时,该CSI参考资源的时域位置为下行时隙n-N-K,
μ
DL和μ
UL分别是下行子载波间隔SCS的索引和上行SCS的索引,N是根据第一信息中的参数确定的,N和K均为非负整数,n'为发送该CSI报告的时隙索引。
在一种可能的设计中,网络设备向终端设备发送第三信息,该第三信息指示K的取值。
第三方面,提供了一种通信装置用于实现上述各种方法。所述通信装置包括实现上述方法相应的模块、单元、或手段(means),该模块、单元、或means可以通过硬件实现,软件实现,或者通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块或单元。

为了方便理解本申请实施例的技术方案,首先给出本申请相关技术或名词的简要介绍如下。
第一,NR***的三大应用场景
典型的eMBB业务有:超高清视频、增强现实(augmented reality,AR)、虚拟现实(virtual reality,VR)等,这些业务的主要特点是传输数据量大、传输速率很高。典型的URLLC业务有:工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用,这些业务的主要特点是要求超高可靠性、低延时,传输数据量较少以及具有突发性。典型的mMTC业务有:智能电网配电自动化、智慧城市等,主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感,这些业务需要满足低成本和非常长的待机时间的需求。
第二,URLLC业务与eMBB业务共存
由于URLLC业务数据的产生具有突发性和随机性,可能在很长一段时间内都不会产生数据包,也可能在很短时间内产生多个数据包。因此,URLLC业务数据的特性会影响通信***的资源分配方式。这里的资源包括但不限于:时域符号、频域资源、时频资源、码字资源以及波束资源等。通常,通信***的资源分配由基站来完成,下面以基站为例进行说明。如果基站采用预留资源的方式为URLLC业务数据分配资源,则在无URLLC业务数据时***资源是浪费的。而且URLLC业务的短时延特性要求数据包在极短的时间内传输完成,所以基站需要预留足够大的带宽给URLLC业务数据,从而导致***资源利用率严重下降。
由于eMBB业务数据的数据量比较大,而且传输速率比较高,因此通常采用较长的时间调度单元进行数据传输以提高传输效率,例如,采用15kHz子载波间隔的一个时隙,对应14个时域符号,对应的时间长度为1毫秒(millisecond,ms)。URLLC业务数据通常采用较短的时间调度单元,以满足超短时延的需求,例如,采用15千赫兹(kilohertz,kHz)子载波间隔的2个时域符号,对应的时间长度为0.14ms,或者采用60kHz子载波间隔的一个时隙,对应14个时域符号,对应的时间长度为0.25ms。
由于URLLC业务数据的突发性,为了提高***资源利用率,基站通常不会为 URLLC业务的下行数据传输预留资源。当URLLC业务数据到达基站时,如果此时没有空闲的时频资源,基站为了满足URLLC业务的超短时延需求,无法等待将本次调度的eMBB业务数据传输完成之后再对URLLC业务数据进行调度。基站可以采用抢占的方式,为URLLC业务数据分配资源。如图1所示,这里的抢占是指基站在已经分配的、用于传输eMBB业务数据的时频资源上选择部分或全部的时频资源用于传输URLLC业务数据。当然,基站在用于传输URLLC业务数据的时频资源上不发送eMBB业务的数据。
需要说明的是,本申请实施例中的时域符号也可以简称为符号(symbol),该符号例如可以为长期演进(long term evolution,LTE)***或者NR***中的正交频分复用(orthogonal frequency division multiplexing,OFDM)符号、离散傅里叶变换扩频OFDM(discrete fourier transform-spread-OFDM,DFT-s-OFDM)符号或者未来移动通信***中的其他符号等。如果没有特别说明,本申请实施例中的符号均指时域符号。
第三,抢占指示(pre-emption indication,PI)
eMBB业务数据资源有可能被突发的URLLC业务数据资源抢占,如果接收eMBB业务数据的终端设备不知道自己的数据资源被抢占,就可能将URLLC业务数据当成自己的数据来进行解调和译码,从而导致译码失败。更严重的是,对于译码失败的传输块,终端设备会将受到URLLC干扰的软值存储下来,和重传的数据进行软值合并译码,从而导致重传时的译码错误。为解决该问题,NR***引入了PI。该PI承载在公共下行控制信息(downlink control information,DCI)中,用14比特(bit)的位图(bitmap)的方式进行表征。其中,bitmap指示一个或多个频域部分(N>=1)和/或一个或多个时域部分(M>=1),{M,N}可以取值为{14,1}或{7,2}。也就是说,首先将时频资源进行分块,这个分块是基站和终端设备都已知的,然后基站会发送bitmap形式的PI,通知终端设备各块资源是否被URLLC业务数据抢占。
目前,承载PI的DCI的发送周期由高层参数配置,以时隙(slot)为单位。假设承载PI的DCI的发送周期为T
INT个时隙,则每个14比特PI指示的时频范围是:
频域:整个激活带宽部分(bandwidth part,BWP)的所有资源块(resource block,RB),记做B
INT个RB。
时域:记做N
INT个时域符号。该N
INT个时域符号为承载PI的DCI对应的物理下行控制信道(physical downlink control channel,PDCCH)的第一个时域符号之前的
个时域符号。其中,T
INT为高层配置的检测PI的周期,
为每时隙的符号数,μ
INT为终端设备接收DCI的BWP对应的子载波间隔索引,μ为应用这个PI的服务小区上的激活BWP对应的子载波间隔索引。此外,若是时分复用(time division duplex,TDD)配置,则N
INT的取值等于
减去高层信令TDD-UL-DL-configuration common或TDD-UL-DL-configuration common中指示的UL时域符号个数。示例性的,如图2所示,PI指示的频域范围为整个BWP,PI指示的N
INT个时域符号为28个时域符号。或者,示例性的,对于TDD配置,如图3所示,PI指示的频域范围为整个BWP,PI指示的N
INT个时域符号为18个时域符号。
目前,根据高层参数配置,PI对应的时频资源有两种划分方式,14bit中每个bit对应的时频子资源也不同。一种可能的方式中,时频块从时间上被分为14份,频率上 不进行划分,对应{14,1}。其中,14bit的PI,每个bit对应一份时频子资源。另一种可能的方式中,时频块从时间上被分为7份,频率上被等分成2份,对应{7,2}。其中,14bit的PI,每2bit分为一组,共七组。比特位图中的比特取0表示该时频资源上可以有该用户的传输(也可以理解为没有被URLLC数据资源抢占);比特取1表示该时频资源上没有该用户的传输。
第四,不能用来发送PDSCH的资源
NR***中,定义了一些不能用来发送PDSCH的资源,称为速率匹配资源。这部分资源可以用来进行NR***的前向或后向兼容,例如在NR资源中周期的划出部分资源给未来的某个***或某个功能使用。如果这些资源和根据DCI确认的PDSCH时频资源块有交集,那么交集的资源不用来传输PDSCH。目前,NR***定义的不能用来发送PDSCH的资源分为三类,包括:RB符号级的资源、资源单元(resource element,RE)级的资源和同步信号(synchronization signal,SS)/物理广播信道(physical broadcast channel,PBCH)块(SS/PBCH block,SSB)资源。其中,本申请下述实施例中主要结合RB symbol级的资源进行描述,在此统一说明,以下不再赘述。
对于RB symbol级的不能用来发送PDSCH的资源,一个终端设备的每个BWP可以配置至多4个BWP级的速率匹配图案(rate matching pattern),每个服务小区可以配置至多4个小区级的速率匹配图案。目前,一个速率匹配图案可以包括:
网络设备配置的一对预留资源,该对预留资源包含一个RB级bitmap,和一个长度为2个slot的symbol级bitmap。其中,RB级bitmap和symbol级bitmap的bit值如果为1,表示对应的资源不能用于发送PDSCH。而对于每对RB级bitmap和symbol级bitmap,可配置一个周期和图案(periodicity and pattern),该periodicity and pattern中的每个bit对应一个symbol级bitmap。其中,若periodicity and pattern中的bit值为1,代表这个单元存在预留资源对。示例性的,假设periodicity and pattern为10,RB级bitmap为00110……11,symbol级bitmap为10……11 01……10,则对应的不能用来发送PDSCH的资源位置可以如图4所示。
需要说明的是,本申请实施例中,包含12个OFDM符号或14个OFDM符号的时间单元在LTE***中称为子帧,对应2个slot;在NR***中对应1个slot。本申请下述实施例中的slot均是以NR***的slot为例进行描述。
第五,CSI-RS
NR***中会配置CSI-RS。目前,CSI-RS分为零功率(zero power,ZP)CSI-RS和NZP CSI-RS。其中,NZP CSI-RS的资源位置上会发送NZP CSI-RS,用来进行CSI测量、层1(layer1,L1)-参考信号接收功率(reference signal received power,RSRP)测量、时频跟踪、移动性测量、无线链路检测等。ZP CSI-RS资源位置上不发送CSI-RS,主要是用来进行PDSCH的速率匹配,PDSCH避开ZP CSI-RS的位置进行映射,避免受到其他终端设备或者其他小区的干扰,也避免干扰其他终端设备或者其他小区的信号。
目前,CSI-RS资源有3种类型,包括:周期,半持续和非周期。其中,周期资源由无线资源控制(radio resource control,RRC)信令配置,配置后周期发送。半持续资源用RRC信令进行配置,用媒体接入控制控制单元(medium access control-control element,MAC-CE)信令进行激活和去激活,激活状态下进行周期发送。非周期资源由RRC信令配置,由物理层的DCI触发。
下面对CSI-RS的资源映射进行相关说明。
对于周期或者半持续的CSI-RS,高层参数会配置以slot为单位的周期和偏置(offset)。其中,周期CSI-RS配置后,或者半持续CSI-RS激活后,终端设备根据周期和offset确定CSI-RS所在的slot。对于非周期的CSI-RS,终端设备可以根据触发DCI确定CSI-RS所在的slot。进而,在某个存在CSI-RS资源的slot内:
在时域上,根据高层配置,时域上可能会有1组或者2组CSI-RS资源,每组包含1个OFDM符号或2个连续的OFDM符号。2组CSI-RS资源之间可以相邻或者间隔若干个OFDM符号。
在频域上,高层信令会配置CSI-RS的频域范围为连续的多个物理资源块(physical resource block,PRB)。每个PRB内或者每间隔1个PRB的PRB内会包含CSI-RS资源。在一个PRB上,CSI-RS资源所在的OFDM符号上,根据高层配置的天线端口(port)数,码分多址(code division multiplexing,CDM)类型等确定CSI-RS资源所在的RE。目前,高层配置的CSI-RS的CDM类型有4种,分别为:noCDM,fd-CDM2,cdm4-FD2-TD2和cdm8-FD2-TD4。其中,noCDM表示CSI-RS没有CDM。fd-CDM2表示CSI-RS在频域的连续两个子载波上进行码分,码长为2。cdm4-FD2-TD2表示CSI-RS在频域的连续两个子载波和时域的连续两个时域符号上进行码分,频域上的码长为2,时域上的码长为2。cdm8-FD2-TD4表示CSI-RS在频域的连续两个子载波和时域的连续四个时域符号上进行码分,频域上的码长为2,时域上的码长为4。
在CSI-RS资源映射中,N个天线端口会在N个RE上做CDM传输。每个天线端口对应1个CDM N的正交码,其对应的CSI-RS信号乘以该正交码后,得到N个信号,在N个RE上传输。也就是说,每个RE上传输的信号是N个天线端口的CSI-RS信号经过正交码处理后的信号叠加。在接收端,必须完整的收到这N个RE上的信号,才能处理得到N个天线端口对应的N个CSI-RS。
下面图示几个例子。其中,图中横轴为时间轴,包含1个slot内的14个OFDM符号,纵轴为频域轴,包含一个PRB内的12个子载波。
示例1,如图5所示,时域包含1组CSI-RS资源,该组CSI-RS资源包含1个OFDM符号,天线端口数为1,CDM类型为noCDM。
示例2,如图6所示,天线端口数为4,CDM类型为fd-CDM2。
示例3,如图7所示,天线端口数为8,CDM类型为fd-CDM2。
示例4,如图8所示,天线端口数为8,CDM类型为cdm4-FD2-TD2。
示例5,如图9所示,天线端口数为24,CDM类型为cdm8-FD2-TD4。
第六,CSI-IM
NR***中会给终端设备配置CSI-IM资源。对于一个终端设备来说,在CSI-IM资源上没有发送给自己的有用信号,终端设备可以在这些资源上测量干扰。
目前,CSI-IM资源有3种类型,包括:周期,半持续和非周期。其中,周期资源由RRC信令配置,配置后周期发送。半持续资源用RRC信令进行配置,用MAC-CE信令进行激活和去激活,激活状态下进行周期发送。非周期资源由RRC信令配置,由 物理层的DCI触发。
下面对CSI-IM的资源映射进行相关说明。
对于周期或者半持续的CSI-IM,高层参数会配置以slot为单位的周期和offset。其中,周期CSI-IM配置后,或者半持续CSI-IM激活后,终端设备根据周期和offset确定CSI-IM所在的slot。对于非周期的CSI-IM,终端设备可以根据触发DCI确定CSI-IM所在的slot。进而,在某个存在CSI-IM资源的slot内:
在频域上,高层信令会配置CSI-IM的频域范围为连续的多个PRB,每个PRB内包含CSI-IM资源。
在时域上,一个CSI-IM资源在一个slot包含4个RE,可以是某个OFDM符号和4个连续子载波对应的4个RE,也可以是2个连续子载波和2个连续OFDM符号对应的4个RE。UE根据高层信令配置可以确定包含CSI-IM的PRB中这4个RE的位置。
第七,CSI测量和CSI报告
首先,给出CSI报告类型和测量资源类型的关系的描述如下。
根据基站的测量配置,终端设备会根据NZP CSI-RS来进行信道测量和/或干扰测量,用CSI-IM来进行干扰测量,并根据高层指示,生成不同类型的CSI,进行报告。
目前,CSI报告可以有以下几种类型:周期报告、半持续报告和非周期报告。CSI报告可以承载在物理上行控制信道(physical uplink control channel,PUCCH)上,也可以承载在物理上行共享信道(physical uplink shared channel,PUSCH)上。下面给出宽带和子带测量的相关描述如下。
在终端设备进行某些测量和报告时,有宽带和子带两种模式。
在进行子带测量时,标称(nominal)子带大小和BWP带宽有关。每种BWP带宽可以对应2种子带大小(如表一所示),高层配置会指示出其中一个。
表一
BWP(PRBs) | 子带大小(PRBs) |
<24 | N/A |
24–72 | 4,8 |
73–144 | 8,16 |
145–275 | 16,32 |
下面给出CSI参考资源的相关描述如下。
一个服务小区的CSI参考资源定义为:
在频域上,CSI参考资源定义为一组下行PRB,对应于生成CSI相关的带宽。
在时域上,一个在上行slot n'上的CSI报告的CSI参考资源定义为一个下行slot n-N。这里,
μ
DL和μ
UL分别是下行子载波间隔(subcarrier spacing,SCS)的索引和上行SCS的索引。N由CSI报告类型等高层参数确定,N为非负整数。
示例性的,假设N为4个slot,则一个服务小区的CSI参考资源的位置示意图可以如图10所示。
如果一个终端设备没有配置高层参数“信道测量时间限制(time restriction for channel measurements)”,则终端设备根据CSI资源配置中不晚于CSI参考资源的 NZP CSI-RS进行信道测量,来获取在上行slot n'上报告的CSI;如果一个终端设备已经配置高层参数“time restriction for channel measurements”,则终端设备根据CSI资源配置中不晚于CSI参考资源的最近的NZP CSI-RS进行信道测量,来获取在上行slot n'上报告的CSI。
如果一个终端设备没有配置高层参数“time restriction for channel measurements”,则终端设备根据CSI资源配置中不晚于CSI参考资源的CSI-IM和/或NZP CSI-RS进行干扰测量,来获取在上行slot n'上报告的CSI;如果一个终端设备已经配置高层参数“time restriction for channel measurements”,则终端设备根据CSI资源配置中不晚于CSI参考资源的最近的CSI-IM和/或NZP CSI-RS进行信道测量,来获取在上行slot n'上报告的CSI。
第八,PDSCH和NZP CSI-RS
NR***中,如果一个用于调度PDSCH的PDCCH的循环冗余校验(cyclic redundancy check,CRC)是用小区无线网络临时标识(cell radio network temporary identifier,C-RNTI)、调制编码方式(modulation and coding scheme,MCS)-C-RNTI和配置调度无线网络临时标识(configured scheduling radio network temporary identifier,CS-RNTI)加扰的,或者PDSCH是一个半持续调度(semi-persistent scheduling,SPS)的PDSCH,则一种可能的实现方式中,在PDSCH资源和NZP CSI-RS有重叠的情况下:
如果是一个非周期NZP CSI-RS,则PDSCH在重叠资源上不做速率匹配;
如果是一个配置了高层参数CSI-RS-Resource-Mobility的NZP CSI-RS,则PDSCH在重叠资源上不做速率匹配;
其他场景下,PDSCH会对NZP CSI-RS做速率匹配。
另一种可能的实现方式中,在PDSCH资源和ZP CSI-RS有重叠的情况下:
如果是一个非本PDSCH的调度PDCCH触发的非周期ZP CSI-RS,则PDSCH在重叠资源上不做速率匹配;否则,在其他场景下,PDSCH会对ZP CSI-RS做速率匹配。
需要注意的是,上面讨论的NZP CSI-RS和ZP CSI-RS是配置的周期NZP CSI-RS和ZP CSI-RS,或者激活的SP NZP CSI-RS和SP ZP CSI-RS,或者触发了的非周期NZP CSI-RS和非周期ZP CSI-RS,不包含没有激活的SP NZP CSI-RS和SP ZP CSI-RS,或者没有触发的非周期NZP CSI-RS和非周期ZP CSI-RS,在此统一说明,以下不再赘述。
可以理解的是,在本申请实施例中,PDCCH、PDSCH、PUCCH和PUSCH仅仅是下行控制信道、下行数据信道、上行控制信道和上行数据信道的举例。下行控制信道、下行数据信道、上行控制信道和上行数据信道在不同的通信***中可能有不同的名称,本申请实施例对此不作限定。

如图14所示,为本申请实施例提供的一种测量方法,该测量方法包括步骤S1401至S1407。
S1401、网络设备向终端设备发送第一信息。相应的,终端设备接收来自网络设备的第一信息。
可选的,本申请实施例中的第一信息可以是承载在网络设备发送给终端设备的高层信令中。一种可能的实现中,该第一信息可以为CSI测量的配置信息,包括测量报告配置,测量资源配置,测量报告和测量资源的关联配置等,相关描述可参考现有第三代合作伙伴项目(3rd generation partnership project,3GPP)技术标准(technical standard,TS)38.331 V15.7.0和TS38.214 V15.7.0,在此不予赘述。

S1403、网络设备向终端设备发送第二信息。相应的,终端设备接收来自网络设备的第二信息。
一种可能的实现方式中,本申请实施例中的第二信息为速率匹配资源的配置信息。该实现方式中,速率匹配资源的配置信息可以是承载在网络设备发送给终端设备的高层信令中。
另一种可能的实现方式中,本申请实施例中的第二信息为PI。该实现方式中,PI可以是承载在网络设备发送给终端设备的DCI中。
S1404、终端设备根据第二信息确定第二资源。
其中,当第二信息为速率匹配资源的配置信息时,本申请实施例中的第二资源为速率匹配资源;当第二信息为PI时,本申请实施例中的第二资源为PI所指示的抢占资源。
需要说明的是,本申请实施例中,当第二资源为PI所指示的抢占资源时,网络设备还可以向终端设备发送PI的配置信息。相应的,终端设备接收来自网络设备的PI的配置信息,PI的配置信息用于确定PI所在的资源位置。
可选的,本申请实施例中的步骤S1403与步骤S1401之间没有必然的执行先后顺序,可以是先执行步骤S1401,再执行步骤S1403;也可以是先执行步骤S1403,再执行步骤S1401,还可以是同时执行步骤S1401和步骤S1403,本申请实施例对此不作具体限定。
S1405、终端设备根据第一资源和第二资源确定第三资源,第三资源包括第一资源中除第一重叠资源之外的部分或全部资源,第一重叠资源为第一资源和第二资源的重叠资源。
可选的,本申请实施例中,第三资源包括第一资源中除第一重叠资源之外的部分或全部资源,具体可以是指:第三资源为第一资源中与第四资源不重叠的资源,第四资源包括第一资源中第一时域符号上的第一频域范围内的资源,第一时域符号为第一重叠资源对应的时域资源中的一个时域符号,第一频域范围包括第二重叠资源所在的频域范围,所述第二重叠资源为第一重叠资源中第一时域符号上的重叠资源。
示例性的,假设第一重叠资源中第一时域符号上的重叠资源(即第二重叠资源)如图15所示,则第一频域范围包括第二重叠资源中的4个RE所在的频域范围。
一种可能的实现方式中,当终端设备进行的测量为宽带测量时,第一频域范围为第一资源对应的频域范围。
例如,本申请实施例中的宽带测量可以包括宽带的CSI测量或者宽带的非CSI测量。宽带的非CSI测量例如可以包括L1-RSRP测量等。
假设第一资源为CSI-RS测量资源,高层配置的CSI-RS的天线端口数为4,CDM类型为fd-CDM2,对应的天线端口的位置分布如图6所示,则当终端设备进行的测量为宽带测量,高层信令配置的CSI-RS测量资源的频域范围为连续的多个PRB,第一重叠资源中第一时域符号上的重叠资源(即第二重叠资源)如图16所示时,第一频域范围为第一时域符号上的这些连续的多个PRB对应的频域范围。即第一频域范围为高层信令配置的第一资源的频域范围。
另一种可能的实现方式中,当终端设备进行的测量为子带测量时,第一频域范围为第二重叠资源所在的子带对应的频域范围。
例如,本申请实施例中的子带测量可以包括子带的CSI测量。
假设第一资源为CSI-RS测量资源,高层配置的CSI-RS的天线端口数为4,CDM类型为fd-CDM2,对应的天线端口的位置分布如图6所示,则当终端设备进行的测量为子带测量,第二重叠资源如图16所示(即其中一个PRB中的4个RE属于子带2,另外一个PRB中的4个RE属于子带3)时,第一频域范围为子带2对应的频域范围和子带3对应的频域范围。即第一频域范围为第二重叠资源所在的子带所包括的PRB。
需要说明的是,上述3个示例均是以一个第一时域符号上的重叠资源为例进行说明,若第一资源和第二资源在多个第一时域符号上重叠,则第四资源包括第一资源中多个第一时域符号上的第一频域范围内的资源,每个第一时域符号上的第一频域范围的确定方式均可以参考上述示例中第一时域符号上的第一频域范围的确定方式,在此不再赘述。
进一步的,第四资源还可以包括第一资源中第二时域符号上的第一频域范围内的资源,第二时域符号为与第二重叠资源有时域CDM关系的时域符号。
假设第一资源为CSI-RS测量资源,高层配置的CSI-RS的天线端口数为8,CDM类型为cdm4-FD2-TD2,对应的天线端口的位置分布如图8所示,第二重叠资源如图17所示,则第四资源不仅包括第二重叠资源中的4个RE,还包括第二重叠资源的相关资源,如第二时域符号上的4个RE。因为第二时域符号上的这4个RE与第一时域 符号上的这4个RE有时域CDM关系,这8个RE上承载的CSI-RS通过CDM映射到8个天线端口,当第一时域符号上的这4个RE上承载的CSI-RS被打孔打掉了,那么第二时域符号上的这4个RE上承载的CSI-RS也无法正确解调。
需要说明的是,上述示例以第一频域范围为第二重叠资源所在的频域范围为例进行说明。当然,第一频域范围也可以是第一资源对应的频域范围,或者,第一频域范围也可以是第二重叠资源所在的子带对应的频域范围,在此不再赘述。
S1406、网络设备确定第一资源和第二资源。
其中,第一资源的相关描述可参考上述步骤S1402,第二资源的相关描述可参考上述步骤S1404,在此不再赘述。
具体的,网络设备可以根据测量的需求确定第一资源。
具体的,当第二资源为速率匹配资源时,网络设备可以根据前向或后向兼容的需求确定第二资源;当第二资源为抢占资源时,网络设备可以根据对URLLC业务数据的调度确定第二资源。
需要说明的是,本申请实施例中的步骤S1406与步骤S1401或步骤S1403之间没有必然的执行先后顺序,可以是先执行步骤S1406,再执行步骤S1401或步骤S1403;也可以是先执行步骤S1401或步骤S1403,再执行步骤S1406,还可以是同时执行步骤S1406与步骤S1401或步骤S1403,本申请实施例对此不作具体限定。
S1407、网络设备根据第一资源和第二资源确定上述第三资源。
其中,网络设备根据第一资源和第二资源确定第三资源的方式可参考步骤S1405中终端设备根据第一资源和第二资源确定上述第三资源的方式,在此不再赘述。
需要说明的是,若上述步骤S1401或步骤S1403在步骤S1406之后执行,则本申请实施例中的步骤S1407与步骤S1401或步骤S1403之间没有必然的执行先后顺序,可以是先执行步骤S1407,再执行步骤S1401或步骤S1403;也可以是先执行步骤S1401或步骤S1403,再执行步骤S1407,还可以是同时执行步骤S1407与步骤S1401或步骤S1403,本申请实施例对此不作具体限定。
进一步的,一种可能的实现方式一中,本申请实施例提供的测量方法还包括如下步骤S1408:
S1408、网络设备在第三资源上向终端设备发送测量信号。相应的,终端设备在第三资源上接收来自网络设备的测量信号。
当第一资源为CSI-RS资源时,这里的测量信号可以为CSI-RS。当第一资源为CSI-IM资源时,这里的测量信号可以为CSI-IM。
或者,另一种可能的实现方式二中,本申请实施例提供的测量方法还包括如下步骤S1409:
S1409、网络设备确定不在第三资源发送信号。
当第一资源为CSI-IM资源时,则不在第三资源上发送的信号例如可以是本小区的PDSCH等有用信号。
进一步的,本申请实施例提供的测量方法还包括如下步骤S1410:
S1410、终端设备在第三资源上进行测量。
当第一资源为CSI-RS资源时,终端设备可以基于在第三资源上接收到的NZP CSI-RS进行信道测量和/或干扰测量;或者,当第一资源为CSI-IM时,终端设备可以在第三资源上进行干扰测量。
基于本申请实施例提供的测量方法,由于本申请实施例中,终端设备在第一资源中除第一重叠资源之外的部分或全部资源上进行测量。也就是说,在第一资源和第二资源的重叠资源上,或者在第一资源和第二资源的重叠资源以及重叠资源的相关资源上,终端设备不进行测量,因此可以避免因为测量资源上其他信号的干扰,造成的测量性能下降的问题。
其中,上述步骤S1401至S1410中的网络设备的动作可以由图12所示的网络设备120中的处理器1201调用存储器1202中存储的应用程序代码来执行,上述步骤S1401至S1410中的终端设备的动作可以由图12所示的终端设备130中的处理器1301调用存储器1302中存储的应用程序代码来执行。
进一步的,结合上述对于PI的描述可知,当第二资源为PI所指示的抢占资源时,PI所指示的抢占资源可以通过基于承载PI的DCI获知;结合上述对于CSI测量和报告的描述可知,一个CSI报告对应一个CSI参考资源,这个CSI报告使用的测量资源不晚于这个CSI参考资源。如图18所示,发送CSI报告的时间对应的下行slot是slot n,CSI参考资源对应的下行slot为slot n-4。也就是说,发送的CSI报告是基于截止时间1之前的测量资源进行测量得到的。假设图18中第二个PI的处理时间是偏置1,则在截止时间2的位置,终端设备知道了其对应的时域范围内的抢占信息,此时才能进行重叠信息的判断。而终端设备本来可以根据偏置2区域内的测量资源进行CSI测量,但是因为要等PI解析完毕,则要到截止时间2处,才能开始CSI测量,这就可能会造成基于偏置2区域内的测量资源获得的CSI报告来不及在时隙n发送。为解决该问题,本申请实施例中,可以设计第一资源的时域资源不晚于CSI报告对应的CSI参考资源的时域位置,当第二资源为PI所指示的抢占资源时,CSI参考资源的时域位置为下行时隙n-N-K,

UL分别是下行子载波的索引和上行子载波的索引,N是根据第一信息中的参数确定的,如根据第一信息中的测量报告配置中该测量对应的CSI资源个数确定,相关描述可参考现有3GPP TS38.331 V15.7.0和TS38.214 V15.7.0,在此不予赘述。其中,N和K均为非负整数,n'为发送CSI报告的时隙索引(也可以称之为时隙号)。
对于K的取值:
一种可能的实现方式中,由网络设备确定K的取值,进而网络设备向终端设备发送第三信息。相应的,终端设备接收来自网络设备的第三信息,其中,第三信息指示K的取值。可选的,本申请实施例中,网络设备可以根据终端设备对PDCCH的处理时间和/或PI的时域周期确定K的取值,当然,网络设备也可以通过其他方式确定K的取值,本申请实施例对此不作具体限定。
另一种可能的实现方式中,由终端设备确定K的取值,比如,终端设备根据对PDCCH的处理时间和/或PI的时域周期,确定K的取值,本申请实施例对此不作具体限定。
示例性的,如图18所示,假设N=4,K=2,则意味着发送的CSI报告是基于截止时间3之前的测量资源进行测量得到的。假设每个PI的解析时间相同,则在截止时间4即可解析得到图18中的第一个PI,此时可以进行重叠信息的判断,进而可以进行 CSI测量。由于截止时间4早于截止时间1,因此在截止时间4开始对截止时间3之前的测量资源上的信号进行测量,得到的CSI报告能来得及在时隙n发送。
