Description

上行满功率传输方法及设备

NR(New Radio,新空口)Rel-15中,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)支持基于码本和非码本的传输,这对PUSCH的功率控制实现提出了更高的要求。基于码本的传输指用户端(User Equipment,UE)根据网络侧的指示选择预编码码本;基于非码本的传输指UE可以根据信道状态信息(Channel State Information,CSI)动态确定预编码码本。
对于基于码本的PUSCH传输,当网络侧配置的用于基于码本传输的探测参考信号(Sounding Reference Signal,SRS)的天线端口数大于1时,PUSCH功率将首先按照非0的PUSCH天线端口和UE的单个SRS资源支持的最大SRS天线端口之比进行缩放,然后在非0的PUSCH天线端口间均分。

图1是本公开的一个实施例中一种上行满功率传输方法的流程图。图1的方法应用于终端设备及网络设备,可包括:
S101,终端设备按照以功率缩放系数进行缩放后的上行传输功率进行上行传输;功率缩放系数由功率控制因子确定。
S102,网络设备接收终端设备发送的上行数据,该上行数据是终端设备按照以功率缩放系数进行缩放后的上行传输功率进行上行传输的。
本实施例中,功率控制因子包括以下至少一项:终端设备的上行满功率传输能力、终端设备上报的支持的传输预编码矩阵指示TPMI、网络设备下发的TPMI、终端设备上报的工作模式、网络设备按照该工作模式配置的探测参考信号SRS资源集中的各SRS资源的天线端口数。
终端设备的上行满功率传输能力包括以下三种UE能力:
第一UE能力:终端设备的各射频支路均支持满功率传输;
第二UE能力:终端设备的各射频支路均不支持满功率传输;
第三UE能力:终端设备的部分射频支路支持满功率传输。
其中,满功率传输指按照终端设备的最大发射功率传输。
当终端设备支持第二UE能力或第三UE能力时,终端设备支持以下两种工作模式:
工作模式一、网络设备配置的SRS资源集中的各SRS资源的天线端口数相同(即用于基于码本传输的SRS资源集合的配置与Rel-15相同);在工作模式一下,终端设备通过网络设备下发的TPMI实现满功率发送。
工作模式二、网络设备配置的SRS资源集中的各SRS资源的天线端口数不同(即用于基于码本传输的SRS资源集合是配置与Rel-15不同);在工作模式二下,终端设备通过网络设备配置的SRS资源的天线端口数指示实现满功率发送。
在本公开实施例中,能够按照以功率缩放系数进行缩放后的上行传输功率进行上行传输,且能够综合考虑多种功率控制因子(包括终端设备的上行满功率传输能力、终端设备上报的支持的传输预编码矩阵指示TPMI、网络设备下发的TPMI、终端设备上报的工作模式、网络设备按照工作模式配置的探测参考信号SRS资源集中的各SRS资源的天线端口数中的至少一项)对上行传输功率进行缩放,从而使上行传输功率得到提升,增强上行覆盖,实现终端设备的上行满功率传输。
上述实施例中,根据功率控制因子的不同,所确定的功率缩放系数的值随之不同。以下详细说明如何根据功率缩放系数来确定功率缩放系数。
实施例一
假设通过上行功率控制计算得到的缩放前的上行功率为P,上行传输的功率缩放系数为α,非0(或非零)上行传输天线端口数为β。其中,非0(或非零)上行传输天线端口指天线端口对应的预编码码本中的行值均非0。
当终端设备支持第一UE能力(如终端设备的各射频支路均支持满功率传输)时,可确定功率缩放系数为1,即α=1。
确定功率缩放系数α=1后,终端设备首先按照功率缩放系数α对上行功率P进行缩放,然后在非0的上行传输天线端口间均分,得到各上行传输天线端口的上行传输功率(即实际传输功率)P′为:
P′=P*α/β
实施例二
假设通过上行功率控制计算得到的缩放前的上行功率为P,上行传输的功率缩放系数为α,非0(或非零)上行传输天线端口数为β。其中,非0(或非零)上行传输天线端口指天线端口对应的预编码码本中的行值均非0,以下可简称非0天线端口数。
当终端设备支持第二UE能力(如终端设备的各射频支路均不支持满功率传输)时,根据UE所支持的工作模式,功率缩放系数α的值有所不同。
具体的,当UE支持工作模式一(如终端设备上报了工作模式一,网络设备根据终端设备上报的工作模式所配置的SRS资源集中的各SRS资源的天线端口数相同)时,可确定功率缩放系数α为非0天线端口数与终端设备上报的单个SRS资源所支持的最大天线端口数之比。
当UE支持工作模式二(如终端设备上报了工作模式一,网络设备根据终端设备上报的工作模式所配置的SRS资源集中的各SRS资源的天线端口数不同)时,可确定功率缩放系数α为非0天线端口数与网络设备配置的SRS资源所支持的最大天线端口数之比。
按照本实施例的方法确定功率缩放系数α后,终端设备首先按照功率缩放系数α对上行功率P进行缩放,然后在非0的上行传输天线端口间均分,得到各上行传输天线端口的上行传输功率(即实际传输功率)P′为:
P′=P*α/β
实施例三
假设通过上行功率控制计算得到的缩放前的上行功率为P,上行传输的功率缩放系数为α,非0(或非零)上行传输天线端口数为β。其中,非0(或非零)上行传输天线端口指天线端口对应的预编码码本中的行值均非0,以下可简称非0天线端口数。
当终端设备支持第三UE能力(如终端设备的部分射频支路支持满功率传输)时,根据UE所支持的工作模式,功率缩放系数α的值有所不同。
具体的,当UE支持工作模式一(如终端设备上报了工作模式一,网络设备根据终端设备上报的工作模式所配置的SRS资源集中的各SRS资源的天线端口数相同)时,可确定功率缩放系数α为非0天线端口数与终端设备上报的单个SRS资源所支持的最大天线端口数之比。
当UE支持工作模式二(如终端设备上报了工作模式一,网络设备根据终端设备上报的工作模式所配置的SRS资源集中的各SRS资源的天线端口数不同)时,根据终端设备是否上报满功率传输的TPMI、以及网络设备下发的TPMI是否位于终端设备上报的TPMI内,功率缩放系数的值也有所不同,具体可分以下三种情况:
a、若终端设备未上报满功率传输的TPMI,则可确定功率缩放系数α为非0天线端口数与网络设备配置的SRS资源所支持的最大天线端口数之比;
b、若终端设备上报了满功率传输的TPMI、且网络设备下发的TPMI位于终端设备上报的TPMI内,则可确定功率缩放系数为1,即α=1。
例如,终端设备上报的TPMI为
Figure PCTCN2020103592-appb-000002
网络设备下发的TPMI为
Figure PCTCN2020103592-appb-000003
显然,网络设备下发的TPMI位于终端设备上报的TPMI内,此时可确定α=1。
c、若终端设备上报了满功率传输的TPMI、且网络设备下发的TPMI不位于终端设备上报的TPMI内,则可确定功率缩放系数α为非0天线端口数与终端设备上报的单个SRS资源所支持的最大天线端口数之比。
例如,终端设备上报的TPMI为
Figure PCTCN2020103592-appb-000004
网络设备下发的TPMI为
Figure PCTCN2020103592-appb-000005
显然,网络设备下发的TPMI不位于终端设备上报的TPMI内,此时可确定α=非0天线端口数β与终端设备上报的单个SRS资源所支持的最大天线端口数之比。
按照本实施例的方法确定功率缩放系数α后,终端设备首先按照功率缩放系数α对上行功率P进行缩放,然后在非0的上行传输天线端口间均分,得到各上行传输天线端口的上行传输功率(即实际传输功率)P′为:
P′=P*α/β
上述任一实施例中,终端设备的上行满功率传输能力可通过以下方式确定:
(1)终端设备上报上行满功率传输能力;或,
(2)终端设备上报上行满功率传输能力、且接收到网络设备下发的上行满功率传输指示;该上行满功率传输指示用于指示终端设备采用上行满功率传输方式进行上行传输。
在方式(2)中,网络设备接收到终端设备上报的上行满功率传输能力后,向终端设备下发上行满功率传输指示。网络设备可采用以下任一种方式向终端设备下发上行满功率传输指示:
方式一、通过无线资源控制RRC、媒体接入控制层MAC或下行控制指示DCI下发上行满功率传输指示。
方式二、下发满功率传输的TPMI,通过TPMI指示终端设备采用上行满功率传输方式进行上行传输。
方式三、为终端设备配置与预编码码本对应的SRS资源;配置的SRS资源的天线端口数与预编码码本指示的非0天线端口数相同。
终端设备上报上行满功率传输能力之后,网络设备可按照如图2所示的步骤进行上行传输。图2的方法可包括以下步骤:
S201,当终端设备上报的上行满功率传输能力为第二UE能力或第三UE能力时,网络设备向终端设备下发TPMI。
其中,网络设备下发的TPMI用于指示终端设备按照由上行传输参数确定的预编码码本进行上行传输。上行传输参数包括终端设备的上行传输天线端口数、上行传输秩数及网络设备配置的SRS资源集中的各SRS资源的天线端口数。
S202,若终端设备的上行传输秩数等于终端设备的上行传输天线端口数,则终端设备按照网络设备下发的TPMI所指示的预编码码本、且以按照功率缩放系数进行缩放后的上行传输功率进行上行传输。
其中,预编码码本根据终端设备的上行传输天线端口数、上行传输秩数及网络设备配置的SRS资源集中的各SRS资源的天线端口数所确定。
S203,若SRS资源集中的各SRS资源的天线端口数不同、且终端设备的上行传输秩数小于上行传输天线端口数,则终端设备按照以功率缩放系数进行缩放后的上行传输功率进行上行传输,但不采用网络设备下发的TPMI所指示的预编码码本。
可选地,若SRS资源集中的各SRS资源的天线端口数不同、且终端设备的上行传输秩数小于上行传输天线端口数,终端设备可按照与上行传输秩数相同的SRS资源的天线端口数对应的SRS资源的传输方式、且以按照功率缩放系数进行缩放后的上行传输功率进行上行传输。
可见,本实施例中,当终端设备支持第二UE能力或第三UE能力、且支持工作模式二时,如果终端设备的上行传输秩数小于上行传输天线端口数,即基于码本传输的SRS资源集合中包含的SRS资源的天线端口数小于SRS资源所支持的最大天线端口数时,TPMI所指示的预编码码本是无用的。此时,终端设备不采用网络设备下发的TPMI所指示的预编码码本,可选地,可按照与上行传输秩数相同的SRS资源的天线端口数对应的SRS资源的传输方式进行上行传输。
以下详细说明网络设备如何根据上行传输参数为终端设备配置预编码码本。
实施例四
本实施例中,终端设备支持第二UE能力或第三UE能力,如终端设备的各射频支路均不支持满功率传输或部分射频支路支持满功率传输。终端设备支持工作模式一,如网络设备配置的SRS资源集中的各SRS资源的天线端口数相同。基于此,预编码码本根据上行传输天线端口数和上行传输秩数的不同也有所不同。具体的:
(1)当上行传输天线端口数为2、且上行传输秩数为1时,可确定预编码码本为:
TPMI=2对应的码本,即

(2)当上行传输天线端口数为4时,根据上行传输秩数的不同,预编码码本可分以下几种情况:

TPMI=12对应的码本,即

实施例五
本实施例中,终端设备支持第二UE能力或第三UE能力,如终端设备的各射频支路均不支持满功率传输或部分射频支路支持满功率传输。终端设备支持工作模式二,如网络设备配置的SRS资源集中的各SRS资源的天线端口数不同。基于此,预编码码本根据上行传输天线端口数、上行传输秩数及各SRS资源的天线端口数的不同也有所不同。具体的:
(1)上行传输天线端口数为2,网络设备配置的SRS资源集中包含2个SRS资源,其中,一个SRS资源包含1个天线端口,另一个SRS资源包含2个天线端口。这种情况下,若网络设备仅配置了1个SRS资源的天线端口,由于终端设备的上行传输秩数小于上行传输天线端口数,即SRS资源集中的各SRS资源的天线端口数小于SRS资源所支持的最大天线端口数,因此TPMI所指示的预编码码本是无用的。此时,终端设备不采用网络设备下发的TPMI所指示的预编码码本,可选地,可按照与上行传输秩数相同的SRS资源的天线端口数对应的SRS资源的传输方式进行上行传输。
(2)上行传输天线端口数为4,根据SRS资源集中包含的SRS资源数及各SRS资源包含的天线端口数的不同,预编码码本也有所不同。具体的:
a、SRS资源集中包括2个SRS资源,且其中一个SRS资源包含1个天线端口,另一个SRS资源包含4个天线端口,则:
当上行传输秩数为1时,由于上行传输秩数小于上行传输天线端口数,即SRS资源集中的各SRS资源的天线端口数小于SRS资源所支持的最大天线端口数,因此TPMI所指示的预编码码本是无用的。此时,终端设备不采用网络设备下发的TPMI所指示的预编码码本,可选地,可按照与上行传输秩数相同的SRS资源的天线端口数对应的SRS资源的传输方式进行上行传输。
当上行传输秩数为2时,可确定预编码码本为:TPMI=6对应的码本,即

或,全相干码本和部分相干和非相干码本;
当上行传输秩数为3时,可确定预编码码本为:TPMI=1对应的码本,即

或,全相干码本和部分相干和非相干码本。
b、SRS资源集中包括3个SRS资源,且其中一个SRS资源包含1个天线端口,另一个SRS资源包含2个天线端口,再一个SRS资源包含4个天线端口,则:
当上行传输秩数为1或2时,由于上行传输秩数小于上行传输天线端口数,即SRS资源集中的各SRS资源的天线端口数小于SRS资源所支持的最大天线端口数,因此TPMI所指示的预编码码本是无用的。此时,终端设备不采用网络设备下发的TPMI所指示的预编码码本,可选地,可按照与上行传输秩数相同的SRS资源的天线端口数 对应的SRS资源的传输方式进行上行传输。
当上行传输秩数为3时,可确定预编码码本为:TPMI=1对应的码本,即
