为便于理解本申请实施例的技术方案,以下对本申请实施例相关的技术方案进行说明。In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此第三代合作伙伴计划(3
rd Generation Partnership Project,3GPP)国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(enhanced Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications,URLLC)、大规模机器类通信(massive Machine-Type Communications,mMTC)。
As people speed, latency, high-speed mobility, energy efficiency and the future of life in the pursuit of the business of diversity, complexity, for the third Generation Partnership Project (3 rd Generation Partnership Project, 3GPP ) ISO began the development of 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).
一方面,eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,例如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。On the one hand, eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.
在NR早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下,可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资,提出了LTE和NR之间紧耦合(tight interworking)的工作模式。In the early deployment of NR, complete NR coverage is difficult to obtain, so the typical network coverage is wide-area LTE coverage and NR island coverage mode. Moreover, a large amount of LTE is deployed below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, and the high frequency band has limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investment in LTE, a tight interworking mode between LTE and NR is proposed.
为了能够尽快实现5G网络部署和商业应用,3GPP首先完成第一个5G版本,即EN-DC(LTE-NR Dual Connectivity)。在EN-DC中,LTE基站(eNB)作为主节点(Master Node,MN),NR基站(gNB或en-gNB)作为辅节点(Secondary Node,SN),连接EPC核心网。在R15后期,将支持其他DC模式,即NE-DC,5GC-EN-DC,NR DC。在NE-DC中,NR基站作为MN,eLTE基站作为SN,连接5GC核心网。在5GC-EN-DC中,eLTE基站作为MN,NR基站作为SN,连接5GC核心网。在NR DC中,NR基站作为MN,NR基站作为SN,连接5GC核心网。In order to achieve 5G network deployment and commercial applications as soon as possible, 3GPP first completed the first 5G version, EN-DC (LTE-NR Dual Connectivity). In EN-DC, an LTE base station (eNB) serves as a master node (Master Node, MN), and an NR base station (gNB or en-gNB) serves as a secondary node (Secondary Node, SN) to connect to the EPC core network. In the later stage of R15, other DC modes will be supported, namely NE-DC, 5GC-EN-DC, and NR DC. In NE-DC, the NR base station serves as the MN, and the eLTE base station serves as the SN to connect to the 5GC core network. In 5GC-EN-DC, eLTE base station serves as MN, NR base station serves as SN, and connects to the 5GC core network. In NR DC, the NR base station serves as the MN, and the NR base station serves as the SN to connect to the 5GC core network.

Typically, the MC architecture may be an MR-MC architecture.
5G为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC激活(RRC_ACTIVE)状态。其中,In order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, 5G defines a new radio resource control (Radio Resource Control, RRC) state, that is, the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. in,
1)RRC_IDLE状态(简称为空闲(idle)态):移动性为基于UE的小区选择重选,寻呼由核心 网(Core Network,CN)发起,寻呼区域由CN配置。基站侧不存在UE上下文,不存在RRC连接。1) RRC_IDLE state (abbreviated as idle state): Mobility is UE-based cell selection and reselection, paging is initiated by the Core Network (CN), and the paging area is configured by the CN. There is no UE context and no RRC connection on the base station side.
2)RRC_CONNECTED状态(简称为连接(connected)态):存在RRC连接,基站侧和UE侧存在UE上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。2) RRC_CONNECTED state (referred to as connected state for short): There is an RRC connection, and UE context exists on the base station side and the UE side. The network side knows that the location of the UE is of a specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.
3)RRC_INACTIVE状态(简称为非激活(inactive)态):移动性为基于UE的小区选择重选,存在CN-NR之间的连接,UE上下文存在某个基站上,寻呼由RAN触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。3) RRC_INACTIVE state (referred to as inactive state for short): Mobility is UE-based cell selection and reselection, there is a connection between CN-NR, UE context is stored on a certain base station, and paging is triggered by RAN, based on The paging area of the RAN is managed by the RAN, and the network side knows that the location of the UE is based on the paging area level of the RAN.
终端设备上报PHR给网络侧,可以辅助网络侧进行更好的上行数据调度和上行功率控制。PHR的类型有:第一类型PHR(type1PHR)、第二类型PHR(type2PHR)、第三类型PHR(type3PHR)。其中,The terminal device reports the PHR to the network side, which can assist the network side to perform better uplink data scheduling and uplink power control. The types of PHR are: the first type PHR (type1PHR), the second type PHR (type2PHR), and the third type PHR (type3PHR). in,
type1 PHR(dB)=PCMAX-PUSCH发射功率。type1 PHR(dB)=PCMAX-PUSCH transmit power.
type2 PHR(dB)=PCMAX-(PUSCH发射功率和PUCCH发射功率)。type2 PHR(dB)=PCMAX-(PUSCH transmit power and PUCCH transmit power).
type3 PHR(dB)=PCMAX–SRS发射功率。type3 PHR (dB) = PCMAX-SRS transmit power.
其中,PCMAX指终端设备的最大发射功率(或者说终端设备支持的最大发射功率)。Among them, PCMAX refers to the maximum transmission power of the terminal equipment (or the maximum transmission power supported by the terminal equipment).
需要说明的是,上述PHR的计算可以基于实际传输计算或者基于参考虚拟传输计算。具体地,PHR的计算基于实际传输计算是指,根据实际传输的PUSCH、或者PUSCH和PUCCH、或者SRS,计算PHR。PHR的计算基于参考虚拟传输计算是指,根据一个参考格式计算PHR,需要说明的是,不同类型的PHR的参考格式有所不同。It should be noted that the calculation of the above-mentioned PHR may be based on actual transmission calculation or based on reference virtual transmission calculation. Specifically, the calculation of the PHR based on actual transmission calculation means that the PHR is calculated according to the actual transmitted PUSCH, or PUSCH and PUCCH, or SRS. The calculation of PHR based on the reference virtual transmission calculation means that the PHR is calculated according to a reference format. It should be noted that the reference format of different types of PHR is different.
在MR-DC场景下,终端设备会上报该终端设备所有激活态小区的PHR,包括MCG侧的激活态小区和SCG侧的激活态小区。例如:例如:图2为上报给NR基站的PHR的格式。C
i(1≤i≤7)对应1个服务小区的索引,C
1至C
7分别对应7个服务小区的索引。C
i的取值用于指示对应的服务小区(Serving Cell)的PHR是否上报。对于每个服务小区(或者说载波)的PHR来说,由2个字节组成,包括如下信息域:P域、V域、PHR域、PCMAX域,其中,P域中的信息用于指示是否应用于了由功率管理造成的功率回退(Power Management-Maximum power Reduction,P-MPR)。V域中的信息用于指示PHR计算是基于一个实际传输还是基于一个参考格式。PHR域中的信息为PHR(也可以简称为PH),其中,该PHR的类型可以是type1PHR或者type2PHR或者type3PHR,不局限于此,PHR的类型还可以增强,例如typex PHR。PCMAX域中的信息为P
CMAX,f,c,PCMAX域是可选地,V域中的信息指示PHR计算是基于实际传输的情况下,需要携带P
CMAX,f,c,V域中的信息指示PHR计算是基于参考格式的情况下,不需要携带P
CMAX,f,c(即P
CMAX,f,c省略不传输)。
In the MR-DC scenario, the terminal device will report the PHR of all active cells of the terminal device, including the active cells on the MCG side and the active cells on the SCG side. For example: Figure 2 shows the format of the PHR reported to the NR base station. C i (1≤i≤7) corresponds to the index of 1 serving cell, and C 1 to C 7 respectively correspond to the indexes of 7 serving cells. The value of C i is used to indicate whether the PHR of the corresponding serving cell (Serving Cell) is reported. For the PHR of each serving cell (or carrier), it consists of 2 bytes, including the following information fields: P field, V field, PHR field, PCMAX field, where the information in the P field is used to indicate whether It is applied to Power Management-Maximum Power Reduction (P-MPR) caused by power management. The information in the V domain is used to indicate whether the PHR calculation is based on an actual transmission or a reference format. The information in the PHR domain is PHR (also referred to as PH for short), where the type of the PHR can be type1PHR, type2PHR, or type3PHR, but is not limited to this. The type of PHR can also be enhanced, such as typex PHR. The information in the PCMAX field is P CMAX,f,c , the PCMAX field is optional, and the information in the V field indicates that the PHR calculation is based on actual transmission, and the information in the P CMAX,f,c ,V field needs to be carried In the case of indicating that the PHR calculation is based on the reference format, it is not necessary to carry P CMAX,f,c (that is, P CMAX,f,c is omitted and not transmitted).
