具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例进行说明之前,对相关内容进行简要说明。
NR系统可支持增强移动带宽(Enhanced Mobile Broadband,eMBB)业务,以满足高速率、高频谱效率以及大带宽的需要。在实际应用中,除了eMBB业务,还存在多种不同的业务类型,例如传感器网络、视频监控以及可穿戴等,这些类型的业务在速率、带宽、功耗和成本等方面与eMBB业务有着不同的需求。支持这些业务的终端设备相比支持eMBB的终端设备的能力是降低的,如支持的带宽减小、处理时间放松以及天线数减少等。因此,需要针对这些业务和相应的低能力终端设备对NR系统进行优化,优化后的的系统称为NR-light系统。在LTE技术中,已经有了类似的系统设计用于支持大连接数、低功耗、低成本的终端,如机器类通信(Machine Type Communication,MTC)和窄带宽物联网(Narrow Band Internet of Thing,NB-IoT)。在NR系统中,希望引入类似的技术用于使用NR技术更好的支持除eMBB业务之外的其他业务类型。支持这类业务的终端设备具有低复杂度、低成本和低能力的特点,称为降低能力终端设备。
降低能力终端设备相比传统的NR终端设备具有低复杂度和低成本的特点,例如减少的接收通道、降低支持的传输带宽等。目前NR终端设备至少需要支持2个接收通道,某些频段上的NR终端设备需要支持4个接收通道;每一个接收通道均包含接收天线,滤波器,功率放大器,模数采样器等元器件,因此,减少NR终端设备需要配备的射频通道数目将可显著降低终端成本。并且,传统NR终端设备需要支持较宽的传输带宽,如对于频率范围FR1,NR终端设备需要支持最大100MHz的带宽,对频率范围FR2,NR终端设备需要支持最大400MHz的带宽。为降低RedCap终端设备的成本以及降低RedCap终端设备的功耗,RedCap终端设备可以支持较小的传输带宽,对于频率范围FR1仅支持20MHz的传输带宽,对于频率范围FR2仅支持100MHz的传输带宽。
另外,降低能力终端设备还可能具有支持较低的峰值速率、支持较宽松的处理时延、以及较大的处理时延等特点。
对于初始接入的终端设备,终端设备在接收到网络设备发送的系统消息之后,发起随机接入过程,与网络设备建立无线资源控制(Radio Resource Control,RRC)连接;在建立RRC连接过程中,网络设备需要识别终端设备的类型为普通的终端设备(非降低能力终端设备)或降低能力终端设备,获取终端设备相关的能力信息。具体的,终端设备可以采用下述任一一种方式指示终端设备的类型:1)在Msg1的发送阶段进行指示,例如通过Msg 1传输所在的初始上行(UpLink,UL)带宽部分(Bandwidth Partment,BWP),通过独立的随机接入(Random Access Channel,RACH)资源,或划分独立的随机接入前导码(preamble)集合。2)在Msg3的发送阶段进行指示,例如承载Msg 3的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的载荷中。3)在Msg4传输之后指示,如Msg5或者作为终端设备的能力上报。4)在2步随机接入MsgA的发送阶段进行指示。
下面对随机接入过程进行简要说明。在NR系统的随机接入过程示意图,如图1所示,采用四步随机接入方式,包括:
第一步,终端设备向网络设备发送包括前导码的随机接入,即终端设备发送消息1(message1,MSG1)。
第二步,网络设备检测到前导码后,向终端设备发送随机接入响应(Random Access Response,RAR)即网络设备发送MSG2。MSG2中携带终端设备发送MSG3可以使用的PUSCH资源,为终端设备分配无线网络临时标识(Radio Network Tempory Identity,RNTI),为终端设备分配时间提前命令(time advance command)。
第三步,终端设备在随机接入响应消息所指示的PUSCH资源发送MSG3,MSG3中携带终端设备特定的临时标识信息。
第四步,网络设备向终端设备发送MSG4,MSG4中包括竞争解决消息,并为终端设备分配上行传输资源。终端设备接收到网络设备发送的MSG4后,会检测终端设备在MSG3发送的终端设备特定的临时标识信息是否包含在基站发送的竞争解决消息中,若包括则表征终端设备随机接入成功,否则认为终端设备随机接入失败;终端设备需要再次从第一步开始发起随机接入过程。
在终端设备的初始接入阶段,如在随机接入过程中,需要通过公共物理上行控制信道(Physical Uplink Control Channel,PUCCH)发送针对Msg4或MsgB的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈信息。由于此时没有终端设备专用的PUCCH资源集合的配置,因此采用预定义方式。预定义的PUCCH资源集合仅用于发送HARQ反馈信息,因此预定义PUCCH资源集合中PUCCH资源仅需承载1~2bit的HARQ反馈信息,即仅由PUCCH格式0和PUCCH格式1构成。网络设备通过系统信息块(System Information Block,SIB1)为所有RRC建立前的终端设备配置一个公共PUCCH资源集合。
终端设备使用通过PUCCH-ConfigCommon中的pucch-ResourceCommon配置的PUCCH资源在初始UL BWP传输HARQ-ACK信息。相关信令如下所示:
PUCCH-ConfigCommon information element
--ASN1START
--TAG-PUCCH-CONFIGCOMMON-START
PUCCH-ConfigCommon::=SEQUENCE{
pucch-ResourceCommon INTEGER(0..15)OPTIONAL,--Cond InitialBWP-Only
pucch-GroupHopping ENUMERATED{neither,enable,disable},
hoppingId INTEGER(0..1023)OPTIONAL,--Need R
p0-nominal INTEGER(-202..24)OPTIONAL,--Need R
...
}
其中,pucch-ResourceCommon指示了表1中的其中一行index,表1中的每一行表示一个公共的PUCCH资源集合。通过表1可以确定对应的PUCCH format、起始符号数、PUCCH Symbol数、频域位置及PUCCH循环移位集合。
表1.指示PUCCH资源配置之前的PUCCH资源集合
Figure PCTCN2021079168-appb-000001
使用pucch-ResourceCommon资源,固定使用跳频方式。PUCCH format 0和PUCCH format 1的参数都可以从上述标1中获取,频域位置和最后一列中的PUCCH循环移位计算过程如下:
对于PUCCH资源,PUCCH发送HARQ-ACK信息的资源索引为γ PUCCH,0≤γ PUCCH≤15。
Figure PCTCN2021079168-appb-000002
其中N CCE是物理下行控制信道(Physical Downlink Control Channel,PDCCH)的资源控制集(Control resource set,CORESET)中的CCE数量,n CCE,0是收到的PDCCH的第一个CCE在CORESET中的索引。△ PRI是format 1_0或format 1_1格式下行控制信息(Downlink Control Information,DCI)中指示的PUCCH资源指示域PUCCH资源指示(resource indicator)的值。

第二跳PRB索引为

其中N CS为初始循环移位索引集合中索引的数量。初始循环移位索引为PUCCH mod(N CS)。

Figure PCTCN2021079168-appb-000008
其中N CS为初始循环移位索引集合中索引的数量,初始循环移位索引为(γ PUCCH-8)mod N CS
相关技术中,终端设备在初始接入过程中,需要通过物理广播信道(Physical Broadcast Channel,PBCH)承载的主信息块(Master Information Block,MIB)信息中获得type0 PDCCH的控制资源集CORESET#0和搜索空间search space#0信息,用于指示type0 PDCCH的在频域上的RB和时域上的符号。CORESET#0信息指示下表中的其中一个index,根据index,得到CORESET#0的RB个数和符号数,以及相比SSB的RB偏移(offset)。对于频率范围FR1,在子载波间隔为15kHz情况下,CORESET#0的带宽可以配置为24、48、96个RB,对应5MHz、10MHz、20MHz的带宽。在30kHz子载波间隔下,CORESET#0配置的最大RB数为48,因此也不会超过20MHz的带宽。终端设备通过type0 PDCCH接收承载SIB的物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)的调度信息,从而接收SIB1信息。对于频率范围FR1来说,RedCap终端设备在初始接入阶段可以支持20MHz带宽,大于或等于CORESET#0的带宽,因此可以成功接收type0 PDCCH。同理,对于频率范围FR2来说,RedCap终端设备在初始接入阶段可以支持100MHz带宽,也大于或等于CORESET#0的带宽。
终端设备可以通过type0 PDCCH接收承载SIB1的物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)的调度信息,从而接收SIB1信息。从SIB1信息中,UE可以获得初始下行BWP(initial DL bandwidth part)和初始上行BWP(initial UL bandwidth part)配置信息。在终端设备的随机接入过程中的信道的发送和接收过程中,可以在初始下行BWP和初始上行BWP上进行。在现有技术中,初始上行BWP配置的带宽允许超过CORESET#0的带宽。如果该小区支持降低能力终端设备的接入,并且沿用现有的初始上行BWP的配置,可能其带宽配置会超过降低能力终端设备的带宽能力,造成降低能力终端设备在初始接入阶段无法正确接收和发送信道。
对于网络设备配置的公共PUCCH资源,其存在于配置的初始上行BWP内。由于降低能力终端设备的带宽可能小于初始上行BWP的带宽,降低能力终端设备支持的带宽内可能不能够包含现有的配置的上行信道的资源,如公共PUCCH资源,造成降低能力终端设备在初始接入阶段无法使用网络配置的公共PUCCH资源。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(wideband code division multiple access,WCDMA)系统、通用分组无线业务(general packet radio service,GPRS)、LTE系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、先进的长期演进(advanced long term evolution,LTE-A)系统、NR系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系 统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、无线局域网(wireless local area networks,WLAN)、无线保真(wireless fidelity,WiFi)、下一代通信系统或其他通信系统等。

本申请实施例提供的随机接入资源确定方法的一种可选处理流程,如图3所示,可以包括以下步骤:
步骤S201,降低能力终端设备基于第一公共物理上行控制信道资源的频域位置和频率偏移,确定第二公共物理上行控制信道资源。
在一些实施例中,所述第二公共PUCCH资源为所述降低能力终端设备对应的带宽内用于发送HARQ反馈信息的资源,所述第一公共PUCCH资源为初始UL BWP对应的用于发送HARQ反馈信息的资源,所述第一公共PUCCH资源由网络设备配置。
在一些实施例中,所述频率偏移包括第一频率偏移和第二频率偏移。
在一些实施例中,所述频率偏移可以由网络设备配置,所述频率偏移也可以根据预定义的规则确定。若所述频率偏移由网络设备配置,则所述降低能力终端设备可以通过接收网络设备发送的系统消息或RRC信令确定频率偏移,即所述系统消息或所述RRC信令中携带所述频率偏移;如网络设备通过PUCCH-ConfigCommon或pucch-ResourceCommon信息向终端设备指示频率偏移。若所述频率偏移由网络设备配置,所述网络设备也可以根据预定义的规则确定频率偏移,再通过系统消息或RRC信令将所确定的频率偏移发送至降低能力终端设备。若网络设备未通过系统消息或RRC信令向降低能力终端设备发送所述频率偏移,则降低能力终端设备也可以根据预定义的规则确定频率偏移。
在一些实施例中,所述预定义的规则可以包括:根据所述初始UL BWP与所述降低能力终端设备对应的带宽的关系确定频率偏移。若所述频率偏移包括的第一频率偏移表示为RBoffset1,所述频率偏移包括的第二频率偏移表示为RBoffset2,初始UL BWP与降低能力终端设备对应的带宽的关系示意图,如图4所示,所述初始UL BWP表示为BW1,所述降低能力终端设备对应的带宽表示为BW2,BW1的中心频率与BW2的中心频率之差表示为CFoffset,则RBoffset1=(BW1-BW2)/2–CFoffset,RBoffset2=(BW1-BW2)/2+CFoffset。即所述第一频率偏移等于所述初始UL BWP与所述降低能力终端设备对应的带宽之差的一半,与所述初始UL BWP与所述降低能力终端设备对应的带宽的中心频率之差的差;所述第二频率偏移等于所述初始上行带宽部分与所述降低能力终端设备对应的带宽之差的一半,与所述UL BWP与所述降低能力终端设备对应的带宽的中心频率之差的和。
在一些实施例中,第一PUCCH资源与第二PUCCH资源的关系示意图,如图5所示,所述第二公共PUCCH资源的第一频域位置为位于所述初始UL BWP的第三频域位置的所述第一公共PUCCH资源增加第一频率偏移;所述第二公共PUCCH资源的第二频域位置为位于所述初始UL BWP的第四频域位置的所述第一公共PUCCH资源减小第二频率偏移;所述第三频域位置的频率小于所述第四频域位置的频率。这里,所述第三频域位置和所述第四频域位置用于传统的终端设备(如非降低能力终端设备)发送混合自动重传请求反馈信息的资源。

开始递减。对于PUCCH的第一跳所在的PRB索引,如图6所示,根据γ PUCCH的值确定在初始UL BWP的第三频率位置或第四频率位置。对于PUCCH的第二跳所在的PRB索引,如图7所示,PUCCH的第二跳与PUCCH的第一跳处于UL BWP的带宽的不同的频率端,若PUCCH的第一跳位于第三频率位置,则PUCCH的第二跳位于第四频率位置。根据图6和图7可知,当初始UL BWP大于降低能力终端设备对应的带宽的情况下,第一公共PUCCH资源的频域资源可能不在降低能力终端设备对应的带宽范围内;在一些场景下,如初始UL BWP的中心频率与降低能力终端设备对应的带宽的中心频率对齐或相差较小的情况下,可能会导致降低能力终端设备没有用于传输HARQ反馈信息的公共PUCCH资源可用。
本申请实施例提供的信道资源确定方法中,如图8所示,所述第二公共PUCCH资源的第一频域位置为位于所述初始UL BWP的第三频域位置的所述第一公共PUCCH资源增加第一频率偏移;所述第二公共PUCCH资源的第二频域位置为位于所述初始UL BWP的第四频域位置的所述第一公共PUCCH资源减小第二频率偏移。即用于降低能力终端设备发送HARQ反馈信息的第二公共PUCCH资源以第一公共PUCCH资源为基础,向初始UL BWP的中心频率偏移,使得第二公共PUCCH资源的频域资源位于降低能力终端设备对应的带宽范围内。
