- the interaction process between the UE and the base station is as follows:
- the UE sends a random access preamble to the base station
- the random access preamble (random access preamble) is the actual content sent by the UE in the physical random access channel.
- the base station feeds back a random access response to the UE
- the base station After detecting that a UE sends a random access preamble, the base station sends a random access response to the UE to inform the UE of available uplink resource information.
- the UE sends an RRC connection recovery request and uplink data to the base station;
- the UE can send an RRC connection resumption request (RRC Connection Resume Request) to the base station on the available uplink resources.
- the RRC connection resumption request can carry a resume identity (resume Identity) and a reason for the resume. (resume Cause) and Short Resume MAC-I (short Resume MAC-I).
- the recovery reason provides the recovery reason such as the RRC connection recovery request provided by the upper layer, the recovery identifier is the UE identifier, and is used to facilitate UE context retrieval (retrieval) at the eNB, and the short recovery MAC-I is the authentication token, Used to facilitate UE authentication at the eNB.
- the base station feeds back the RRC connection release request and downlink data to the UE.
- the base station may analyze each field in the RRC connection recovery request, and after determining the purpose of the RRC connection recovery request, send the RRC connection release request and the RRC connection recovery request to the UE. Downlink data, thus realizing small data transmission between the UE and the base station.
- the RRC connection release request may carry a release cause (release Cause), a release identity (release Identity) and a next hop chaining counter (next hop chaining counter, NCC).
- the release reason is used to notify the UE to perform a suspend operation and enter an inactive state.
- the NCC is an optional parameter, and the NCC is a parameter required by the UE when the UE enters the connected state from the inactive state. If the RRC connection release request carries the NCC, the access stratum key used by the subsequent UE and the base station will be updated. NCC is a parameter required to generate a new access stratum key, that is, NCC can be used to generate a new access stratum key. If the RRC connection release request does not carry the NCC, the access stratum key used by the subsequent UE and the base station will not be updated, that is, it will remain unchanged.
- the UE completes the transmission of small data packets before entering the connected state.
- the network will configure a maximum transmission block size (TB size) that the current network allows transmission on the system information block 2 (system information block 2, SIB2), and the amount of data to be transmitted by the UE is less than or equal to
- TB size the maximum transmission block size of the broadcast
- SIB2 system information block 2
- the UE can initiate EDT transmission; otherwise, the UE uses the normal connection establishment process to enter the connected state to transmit data.
- FIG. 3 is an interactive schematic diagram of data transmission based on PUR.
- the PUR-based data transmission method may include the following steps:
- the UE determines that it has a valid PUR
- the UE sends an RRC connection recovery request and uplink data to the base station;
- the UE When the UE determines that it has a valid PUR, it can send an RRC connection resumption request (RRC Connection Resume Request) and uplink data to the base station.
- the RRC connection resumption request can carry a resume Identity, an establishment cause and a short Resume MAC-I (short Resume MAC-I).
- the establishment reason provides the establishment reason for the RRC connection recovery request
- the recovery identifier is the UE identifier, which is used to facilitate UE context retrieval (retrieval) at the eNB
- the short recovery MAC-I is the authentication token, which is used to facilitate the retrieval of the UE context at the eNB.
- UE authentication
- the base station feeds back the RRC connection release request, downlink data and timing advance command to the UE.
- the base station may analyze each field in the RRC connection recovery request, and after determining the purpose of the RRC connection recovery request, send the RRC connection release request, Downlink data and timing advance commands, thus realizing small data transmission between the UE and the base station.
- the RRC connection release request may carry a release cause (release Cause), a release identity (release Identity) and a next hop chaining counter (next hop chaining counter, NCC).
- release Cause a release cause
- release Identity release Identity
- NCC next hop chaining counter
- the PUR transmission process is similar to the LTE UP-EDT, except that the process of sending a preamble to obtain a timing advance (TA) and an uplink grant (UL grant) is omitted.
- TA is generally used for UE uplink transmission, which means that in order to reach the UE uplink packet to the eNB at the desired time, the radio frequency transmission delay caused by the distance is first estimated, and the data packet is sent out in advance of the corresponding time.
- the conditions for judging whether the TA is valid include at least one of the following: the TA timer is in the running state, the reference signal received power (reference signal received power, RSRP) change (increase or decrease) not more than or not less than the set threshold.
- the configuration of the TA timer is sent to the UE through an RRC Connection Release (RRC Connection Release) message.
- RRC Connection Release RRC Connection Release
- the RRC layer in the UE instructs the MAC layer to apply or release the corresponding configuration according to the configuration information of the TA timer.
- the RRC layer in the UE determines whether the pre-configured uplink resource configuration information (pur-Config) is included, if not, the UE keeps the existing configuration unchanged, and the TA timer does not restart; If included, the RRC layer in the UE performs one of the following actions according to the pur-Config configuration:
- the UE stores or replaces the PUR configuration. If the pur-Config contains the PUR time alignment timer (pur-TimeAlignmentTimer), the RRC layer in the UE instructs the lower layer to apply the pur-TimeAlignmentTimer; If pur-Config does not contain pur-TimeAlignmentTimer, the RRC layer instructs the lower layer to release pur-TimeAlignmentTimer;
- the UE releases the PUR configuration and instructs the lower layer to release the pur-TimeAlignmentTimer.
- the TA timer in PUR transmission is maintained by the MAC layer. If the MAC layer receives the pur-TimeAlignmentTimer configured by the upper layer, it starts or restarts the timer; if the MAC layer receives the upper layer's instruction to release the pur-TimeAlignmentTimer, it stops the timer. In addition, in addition to starting or restarting the TA timer according to the instructions of the upper layer, the MAC also needs to command the MAC knowable element (timing advance command mac control element, TAC MAC CE) according to the received timing advance command or the physical downlink control channel (physical downlink control channel). , PDCCH) indicates the time adjustment amount, start or restart the TA timer.
- TAC MAC CE timing advance command mac control element
- PDCCH indicates the time adjustment amount, start or restart the TA timer.

下面首先介绍一下提出本申请技术方案的背景:
现阶段,针对人们对速率、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,第三代合作伙伴计划(3rd generation partnership project,3GPP)国际标准组织开始研发第五代(5th-generation,5G)移动通信技术。5G移动通信技术的主要应用场景为:增强移动超宽带(enhanced mobile broadband,eMBB)、低时延高可靠通信(ultra-reliable and low latency communications,URLLC)、大规模机器类通信(massive machine type of communication,mMTC)。
在实际应用中,无线资源控制(Radio Resource Control,RRC)主要用于在有限带宽的条件下,为网络内无线用户终端提供业务质量保障,其能够在网络话务量分布不均匀、信道特性因信道衰弱和干扰而起伏变化等情况下,灵活分配和动态调整无线传输部分和网络的可用资源,最大程度地提高无线频谱利用率,防止网络拥塞和保持尽可能小的信令负荷。
下面针对本申请实施例涉及的5G RRC状态进行解释说明:
在5G NG系统中,RRC支持三种状态,RRC空闲态(RRC_IDLE)、RRC非激活态(RRC_INACTIVE)、RRC连接态(RRC_CONNECTED)。其中,RRC_INACTIVE是为了在5G的网络环境中,降低空口信令、快速恢复网络侧与终端设备之间的无线连接,以快速恢复数据业务而引入的新状态,其与RRC_IDLE、RRC_CONNECTED不同。
具体的,对于RRC_IDLE状态,移动性为基于用户设备(user equipment,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。基站侧不存在用户设备接入层(UE access stratum,UE AS)的上下文,网络侧与终端设备之间不存在RRC的连接。
对于RRC_CONNECTED状态,网络侧与UE之间存在RRC连接,基站和UE中均存在UE AS上下文,网络侧获知的UE位置是小区级别的。此时,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。
对于RRC_INACTIVE状态,移动性是基于UE的小区选择或重选,存在CN-NR之间的连接,UE AS的上下文存在某个基站上,寻呼由无线接入网(wireless access network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络侧获知的UE位置是基于RAN的寻呼区域级别的。
也即,在RRC_INACTIVE状态下,无线承载和全部无线资源都会被释放,但RRC和NAS上下文仍部分保留在终端、基站和核心网中,此时,终端状态几乎与RRC_IDLE状态的相同,因此更省电,同时,还可快速从RRC_INACTIVE状态恢复到RRC_CONNECTED状态,减少信令数量,非常适合小数据包发送的百万级大规模物联网业务和时延敏感的URLLC业务。因而,网络通常将数据传输不频繁的UE保持在RRC_INACTIVE态。
在5G规范的第二个版本(Rel-16)之前,处于RRC_INACTIVE状态的UE不支持数据传输,当短信上行(message original,MO)数据或短信下行(mobile terminate,MT)数据到达时,UE需要恢复到RRC_CONNECTED状态,当待数据传输完成后再释放到RRC_INACTIVE状态。其中,MO数据是用户上发给服务提供商(service provider,SP) 的信息,MT数据意是SP端下发给用户的信息,SP是增值业务提供商,负责根据用户的要求开发和提供适合终端用户使用的服务。
上述传输机制,对于数据量小且传输频率低的UE,会存在不必要的功耗和信令开销。因此,在5G规范的第三个版本(Rel-17)中立项开展对RRC_INACTIVE状态下小数据传输(small data transmission,SDT)的研究,项目目标主要有两个方向:基于随机接入过程(两步/四步)的上行小数据传输以及基于预配置资源(如配置授权(configure grant,CG)类型1(type1))的上行小数据传输。
在Rel-17的某个会议上,关于基于CG的SDT得到以下结论:当UE处于连接态时,网络可以通过RRC释放(RRCRelease)消息将UE释放到非激活态的同时,通过RRCRelease消息为UE配置用于非激活态数据传输的CG资源;当UE处于非激活态时,网络可以通过RRCRelease消息为UE重配置或释放CG资源。
然而,基于现有进展,目前仍没有统一的标准来明确网络如何通过RRCRelease消息重配置或释放CG资源。针对上述技术问题,本申请实施例提供了一种资源处理方法,终端设备在接收到第一RRC释放消息时,且该第一RRC释放消息用于指示进入RRC非激活态,这时可以根据第一RRC释放消息是否包含配置信息来对CG资源配置信息进行处理,例如,配置或重配置或释放CG资源配置信息等。该技术方案明确了网络如何通过RRC释放消息为终端设备重配置或释放CG资源的方案,在保证数据传输稳定性的前提下,减少了不必要的功耗和信令开销。
下述在介绍本申请的技术方案之前,首先结合长期演进技术(long term evolution,LTE)中的某些现有技术对本申请的技术构思进行解释说明:
LTE中的上行小数据传输(LTE UP EDT)
在LTE中,已经引入了EDT,即小数据传输,在该过程中,UE可能始终保持在空闲(idle)状态或者挂起(suspend)状态或者非激活(inactive)状态,完成上行和/或下行小数据包的传输。
示例性的,图2为基于上行的小数据传输的交互示意图。如图2所示,在UE有上行传输的需求时,UE和基站首先执行随机接入过程,即UE发送随机接入前导码开始尝试接入网络,到与网络建立起基本的信令连接之前的过程。具体的,UE和基站的交互过程如下:
1、UE向基站发送随机接入前导码;
其中,该随机接入前导码(random access preamble)是UE在物理随机接入信道中发送的实际内容。
2、基站向UE反馈随机接入响应;
基站在检测到有UE发送随机接入前导码之后,便向UE发送随机接入响应,以告知UE可以使用的上行资源信息。
3、UE向基站发送RRC连接恢复请求和上行数据;
UE在接收到随机接入响应后,便可以在能够使用的上行资源上,向基站发送RRC连接恢复请求(RRC Connection Resume Request),该RRC连接恢复请求可以携带恢复标识(resume Identity)、恢复原因(resume Cause)和短恢复MAC-I(short Resume MAC-I)。可选的,恢复原因提供如由更上层提供的RRC连接恢复请求的恢复原因,恢复标识是UE标识,用于促进eNB处的UE上下文检索(retrieval),短恢复MAC-I是认证令牌,用于促进eNB处的UE认证。
4、基站向UE反馈RRC连接释放请求和下行数据。
可选的,基站在接收到RRC连接恢复请求和上行数据后,可以对RRC连接恢复请求中的各字段进行分析,并在确定出RRC连接恢复请求的目的之后,向UE发送RRC连接释放请求和下行数据,从而实现了UE与基站之间的小数据传输。
可选的,RRC连接释放请求可以携带释放原因(release Cause)、释放标识(release Identity)和下一跳链计数器(next hop chaining counter,NCC)。其中,释放原因用于通知UE执行挂起操作并进入不活跃态。NCC是可选参数,NCC是UE后续从不活跃态进入连接态时所需要的参数。如果RRC连接释放请求中携带NCC,则后续UE和基站所使用的接入层密钥将会发生更新。NCC是生成新的接入层密钥所需要的参数,即NCC可用于生成新的接入层密钥。如果RRC连接释放请求中不携带NCC,则后续UE和基站所使用的接入层密钥将不发生更新,即始终保持不变。
由UE和基站的交互过程可知,对于EDT过程,UE在没有进入连接状态之前就完成了小数据包的传输。这时,在配置上,网络会在系统消息块2(system information block 2,SIB2)上配置一个当前网络允许传输的最大传输块大小(TB size),UE在自己待传输的数据量小于或等于这个广播的最大TB size时,则UE可以发起EDT传输;反之,UE使用正常的连接建立过程,进入连接态传输数据。
预配置上行资源(preconfigured uplink resource,PUR)传输
在LTE的Rel-16中,针对窄带物联网(narrow band internet of things,NB-IoT)和增强型机器类型通信(enhanced machine-type communication,eMTC)场景,引入了在空闲态上,利用PUR进行数据传输的方法。
示例性的,图3为基于PUR进行数据传输的交互示意图。如图3所示,基于PUR的数据传输方法可以包括如下步骤:
1、UE确定具有有效的PUR;
2、UE向基站发送RRC连接恢复请求和上行数据;
UE在确定具有有效的PUR时,便可以向基站发送RRC连接恢复请求(RRC Connection Resume Request)和上行数据,该RRC连接恢复请求可以携带恢复标识(resume Identity)、建立原因(establishment Cause)和短恢复MAC-I(short Resume MAC-I)。可选的,建立原因提供RRC连接恢复请求的建立原因,恢复标识是UE标识,用于促进eNB处的UE上下文检索(retrieval),短恢复MAC-I是认证令牌,用于促进eNB处的UE认证。
3、基站向UE反馈RRC连接释放请求、下行数据和定时提前命令。
可选的,基站在接收到RRC连接恢复请求和上行数据后,可以对RRC连接恢复请求中的各字段进行分析,并在确定出RRC连接恢复请求的目的之后,向UE发送RRC连接释放请求、下行数据和定时提前命令,从而实现了UE与基站之间的小数据传输。
可选的,RRC连接释放请求可以携带释放原因(release Cause)、释放标识(release Identity)和下一跳链计数器(next hop chaining counter,NCC)。关于释放原因、释放标识和NCC的具体作用可以参见上述图2所示实施例中的记载,此处不作赘述。
由上述分析可知,PUR只在当前配置的小区内有效,因而,在UE检测到小区变化,并在新的小区发起随机接入时,UE需要释放原小区配置的PUR。PUR传输流程和LTE UP-EDT类似,只是省去了发送前导码获取定时提前(timing advance,TA)和上行授权(UL grant)的过程。其中,TA一般用于UE上行传输,指为了将UE上行包在希望的时间到达eNB,首先预估由于距离引起的射频传输时延,以提前相应时间发出数据包。
在实际应用中,UE利用PUR执行数据传输的一个重要前提是具有有效的TA,根据协议规定,判断TA是否有效的条件包含以下至少一个:TA定时器处于运行状态、参考信号接收功率(reference signal received power,RSRP)变化(增大或减小)不大于或不小于设定的阈值。
其中,TA定时器的配置作为PUR配置的一部分,通过RRC连接释放(RRC Connection Release)消息下发给UE。UE中的RRC层根据TA定时器的配置信息,指示MAC层应用或释放相应的配置。
具体的,UE中的RRC层在收到RRC Connection Release消息后,判断是否包含预配置上行资源配置信息(pur-Config),若不包含,UE保持现有配置不变,TA定时器不重启;若包含,UE中的RRC层根据pur-Config配置执行以下行为中的一种:
1、若pur-Config设置为安装(setup),UE存储或替代PUR配置,若pur-Config中包含PUR时间校准定时器(pur-TimeAlignmentTimer),则UE中的RRC层指示低层应用pur-TimeAlignmentTimer;若pur-Config中不包含pur-TimeAlignmentTimer,则RRC层指示低层释放pur-TimeAlignmentTimer;
2、若pur-Config设置为释放(release),UE释放PUR配置,并指示低层释放pur-TimeAlignmentTimer。
PUR传输中的TA定时器由MAC层维护,若MAC层在收到高层配置的pur-TimeAlignmentTimer,则启动或重启timer;若MAC层收到高层释放pur-TimeAlignmentTimer的指示,则停止timer。此外,MAC除了根据高层指示启动或重启TA定时器外,还需要根据接收到的定时提前命令MAC可知单元(timing advance command mac control element,TAC MAC CE)或由物理下行控制信道(physical downlink control channel,PDCCH)指示的时间调整量,启动或重启TA定时器。
基于上述内容,本申请的技术构思过程如下:鉴于LTE中,UE和基站可以通过RRC连接请求或RRC释放请求中携带的信息实现小数据的数据传输的配置,因而,在5G NR系统中是否也可以通过在RRC释放消息中配置一些信息,用于指示UE中CG资源的处理方式,从而明确规定网络对终端设备重配置或释放CG资源的方案,以保证数据传输稳定性和减少了不必要的功耗和信令开销。
基于上述提出的技术方案和技术构思过程,下面通过具体实施例对本申请的技术方案进行详细说明。需要说明的是,本申请的技术方案可以包括以下内容中的部分或全部,下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图4为本申请实施例提供的资源处理方法实施例一的交互示意图。该方法以终端设备和网络设备之间的信息交互进行解释说明。如图4所示,该资源处理方法可以包括如下步骤:
S401、网络设备向终端设备发送第一RRC释放消息,该第一RRC释放消息用于指示进入RRC非激活态。
在实际应用中,对于某些业务,例如,一些社交媒体类的应用,有时候,终端设备发送的数据包的间隔时间会比较长,在这种情况下,为了降低终端设备耗能,也为了降低用户信令面的时延,网络设备可以向终端设备发送第一RRC释放消息,以指示终端设备进入RRC非激活态。
可选的,在本申请的实施例中,该终端设备可以是处于RRC连接态(RRC_CONNECTED态)的终端设备,也可以是处于RRC非激活态(/RRC_INACTIVE态)的终端设备,本申请实施例并不对终端设备实际所处的RRC状态进行限定。该第一RRC释放消息是携带挂起配置信息的RRCRelease消息,例如,RRCRelease with suspendConfig消息。
S402、终端设备根据接收到的第一RRC释放消息是否包含配置信息,对CG资源配置信息进行处理。
示例性的,终端设备在接收到网络设备(网络侧)发送的第一RRC释放消息(RRCRelease with suspendConfig消息)后,在进入RRC非激活态之前,可以根据第一RRC释放消息是否包含配置信息,确定CG资源配置信息的处理方案。
可选的,在本申请的实施例中,该CG资源配置信息可以是终端设备中原先存储的CG资源配置信息,也可以是第一RRC释放消息包含配置信息时,该配置信息指示的配置 或重配置CG资源配置信息。本申请实施例并不对该步骤中的CG资源配置信息的具体含义进行限定,其可以根据实际场景确定,此处不作赘述。
在实际应用中,终端设备在接收到第一RRC释放消息后,为了准确的对CG资源配置信息进行处理,还可以需要结合终端设备中是否存在用于非激活态数据传输的目标CG资源进行判断。因而,在本申请的实施例中,上述S402可以通过如下步骤实现:
A1、确定终端设备中是否存在用于非激活态数据传输的目标CG资源。
A2、根据第一RRC释放消息是否包含配置信息和终端设备中是否存在用于非激活态数据传输的目标CG资源,对CG资源配置信息进行处理。
具体的,终端设备可以通过查询本身拥有的资源信息,确定出终端设备内部是否存储有用于非激活态数据传输的目标CG资源,进而再结合接收到第一RRC释放消息是否具有针对CG资源的处理指示,来明确出CG资源的处理方案。
本申请实施例提供的资源处理方法,终端设备在接收到用于指示进入RRC非激活态的第一RRC释放消息时,可以根据第一RRC释放消息是否包含配置信息来对CG资源配置信息进行处理,例如,配置或重配置或释放CG资源配置信息等。该技术方案明确了网络如何通过RRC释放消息为终端设备重配置或释放CG资源的方案,在保证数据传输稳定性的前提下,减少了不必要的功耗和信令开销。
示例性的,在上述实施例的基础上,图5为本申请实施例提供的资源处理方法实施例二的流程示意图。该资源处理方法的执行主体为终端设备。如图5所示,作为一种示例,若上述配置信息包括:用于配置或重配置CG资源的第一配置信息;相应的,上述S402中的A2(根据第一RRC释放消息是否包含配置信息和终端设备中是否存在用于非激活态数据传输的目标CG资源,对CG资源配置信息进行处理)具体可以通过如下步骤实现:
S501、判断第一RRC释放消息中是否包含第一配置信息;若是,则执行S502;若否,则执行S505。
示例性的,在本申请的实施例中,网络设备可以通过在第一RRC释放消息中是否包含配置信息或者包含不同的配置信息指示终端设备执行不同的操作过程。
例如,网络设备和终端设备约定了:第一配置信息用于配置或重配置CG资源。即,通过第一配置信息显示指示配置或重配置CG资源及其配置信息,而隐式指示释放CG资源和CG资源的配置信息。因而,终端设备在接收到第一RRC释放消息后,首先需要判断该第一RRC释放消息中包含该第一配置信息,进而执行不同的操作。
可选的,若第一RRCRelease消息中包含第一配置信息,则UE存储或替换CG资源及其配置信息;若第一RRCRelease消息中不包含第一配置信息,则UE释放当前存储的CG资源及其配置信息。
S502、确定终端设备中是否存在用于非激活态数据传输的目标CG资源;若是,则执行S503;若否,则执行S504。
可选的,终端设备在确定第一RRC释放消息包含第一配置信息时,可能执行存储CG资源及其配置信息的操作,也可能执行替换CG资源及其配置信息的操作,这时需要结合终端设备中是否存在用于非激活态数据传输的目标CG资源具体确定。
S503、利用第一配置信息配置或重配置的CG资源和CG资源的配置信息替换所述目标CG资源和所述目标CG资源的配置信息。
作为一种示例,若第一RRC释放消息包含第一配置信息且终端设备中存在用于非激活态数据传输的目标CG资源,这时为了保证终端设备能够在RRC非激活态下实现更精确的数据传输,此时可以利用第一配置信息配置或重配置的CG资源和该CG资源的配置信息替换掉终端设备中存储的目标CG资源和目标CG资源的配置信息,从而实现对终端设备内部CG资源及其配置信息的更新。
S504、存储第一配置信息配置或重配置的CG资源和CG资源的配置信息。
作为另一种示例,若第一RRC释放消息包含第一配置信息且终端设备中不存在用于非激活态数据传输的目标CG资源,此时可以根据第一配置信息,存储该第一配置信息配置或重配置的CG资源和CG资源的配置信息,以保证终端设备能够在RRC非激活态执行正常的数据传输。
S505、确定终端设备中是否存在用于非激活态数据传输的目标CG资源;若是,则执行S506;若否,结束。
可选的,在本申请的实施例中,当第一RRCRelease消息中不包含第一配置信息时,此时,网络设备隐式指示终端设备中不需要存储用于非激活态数据传输的目标CG资源及其配置信息,因而,终端设备可以根据其内部当前是否存储有目标CG资源来执行不同的操作。可以理解的是,S505的具体实现方案与S502的具体实现类似,此处不作赘述。
S506、释放目标CG资源和该目标CG资源的配置信息。
具体的,若终端设备接收到的第一RRC释放消息不包含第一配置信息,但终端设备中存在用于非激活态数据传输的目标CG资源,由于网络设备隐式指示终端设备中不需要存储用于非激活态数据传输的目标CG资源及其配置信息,终端设备便可以将当前存储的目标CG资源和目标CG资源的配置信息释放掉,以减少资源占用空间。
本申请实施例提供的资源处理方法,配置信息包括用于配置或重配置CG资源的第一配置信息,此时,若第一RRC释放消息包括第一配置信息且终端设备内部未存储用于非激活态数据传输的CG资源,终端设备根据第一配置信息存储CG资源及配置,第一RRC释放消息包括第一配置信息且终端设备内部存储用于非激活态数据传输的CG资源,则根据第一配置信息替换当前的CG资源及配置,而且在第一RRC释放消息不包括第一配置信息且终端设备内部存储用于非激活态数据传输的CG资源时,释放当前CG资源及配置。该技术方案通过第一配置信息显示指示配置或重配置CG资源,隐式指示释放CG资源,明确了终端设备在RRC非激活状态下的CG资源处理方案,从而为后续数据的正常传输奠定了实现基础。
示例性的,在上述图5所示实施例的基础上,图6为本申请实施例提供的资源处理方法实施例三的流程示意图。如图6所示,作为另一种示例,若上述配置信息还包括:用于指示释放所述终端设备中的目标CG资源的第二配置信息;相应的,在本申请的实施例中,在上述S501(判断第一RRC释放消息中是否包含第一配置信息)之后,若否,则执行S601。
S601、判断第一RRC释放消息中是否包含第二配置信息;若是,执行S602;若否,执行S604。
在本申请的实施例中,网络设备和终端设备还可以约定:通过第一配置信息指示配置或重配置CG资源,通过第二配置信息指示释放CG资源,而隐式指示保留终端设备中的CG资源和CG资源的配置信息。
示例性的,终端设备在确定第一RRC释放消息中不包含该第一配置信息时,可以确定终端设备无需执行替换或存储CG资源及其配置信息的操作,这时再判断该第一RRC释放消息中是否包含第二配置信息来确定是否需要释放掉终端设备内当前存储的CG资源及其配置信息。
S602、确定终端设备中是否存在用于非激活态数据传输的目标CG资源;若是,则执行S603;若否,则结束。
可选的,如果网络设备需要释放CG资源及其配置信息,这时需要首先判断终端设备内部是否存在目标CG资源,进而根据判断结果确定是否需要继续执行。
S603、释放目标CG资源和目标CG资源的配置信息。
作为一种示例,若第一RRC释放消息包含第二配置信息且终端设备中存在用于非激活态数据传输的目标CG资源,这时,可以基于网络设备的指示,将存储的目标CG资源和目标CG资源的配置信息释放掉,以减少存储空间的占用。
S604、确定终端设备中是否存在用于非激活态数据传输的目标CG资源;若是,则执行S605;若否,则结束。
可以理解的是,S602、S604与上述S502、S505的具体确定步骤类似,此处不作说明。
S605、保留目标CG资源和所述目标CG资源的配置信息。
示例性的,终端设备在确定第一RRC释放消息中既不包含第一配置信息,也不包含第二配置信息时,可以确定终端设备既不需要替换CG资源及其配置信息,也不需要存储CG资源及其配置信息,也不需要释放当前存储的CG资源及其配置信息,因而,在终端设备中存在用于非激活态数据传输的目标CG资源时,终端设备可以保持内部中CG资源的原有配置不变,即若第一RRC释放消息中既不包含第一配置信息又不包含第二配置信息,且终端设备内部存有用于非激活态数据传输的目标CG资源,这时,终端设备可以沿用当前CG资源及配置不变。
可以理解的是,本申请实施例并不对上述各步骤的具体执行顺序进行限定,其可以根据实际需要确定,例如,也可以判断终端设备中存在用于非激活态数据传输的目标CG资源,再判断第一RRC释放消息中是否包含第一配置信息或第二配置信息,此处不作赘述。
本申请实施例提供的资源处理方法,在配置信息包含用于配置或重配置CG资源的第一配置信息和用于指示释放终端设备中的目标CG资源的第二配置信息时,若终端设备确定第一RRC释放消息包含第二配置信息且终端设备中存在用于非激活态数据传输的目标CG资源,则释放存储的目标CG资源和目标CG资源的配置信息,而若第一RRC释放消息中既不包含第一配置信息又不包含第二配置信息,且终端设备内部存有用于非激活态数据传输的目标CG资源,则保留当前CG资源及配置不变。该技术方案中,通过第一RRC释放消息显示指示配置或重配置或释放CG资源,而隐式指示沿用CG资源的当前配置,同样明确了终端设备在RRC非激活状态下的CG资源处理方案,为后续数据的正常传输提供了实现条件。
进一步的,在上述图5所示实施例的基础上,在上述配置信息包括:用于配置或重配置CG资源的第一配置信息时,该资源处理方法还可以包括如下步骤:
根据第一配置信息是否包括配置指示信息,确定第一配置信息配置或重配置CG资源的资源配置方式。
其中,配置指示信息用于指示第一配置信息配置或重配置CG资源的资源配置方式。
示例性的,在本申请的实施例中,第一配置信息可以包含完整的CG资源配置参数或对于当前CG资源配置信息的调整信息;其中,完整的CG资源配置参数用于在非激活态数据传输时确定CG资源配置信息;当前CG资源配置信息为连接态数据传输时使用的CG资源配置信息或非激活态数据传输时使用的CG资源配置信息。
其中,完整的CG资源配置参数可以包括:一个或多个预配置授权配置(ConfiguredGrantConfg),每个预配置授权配置用于指示周期性出现的CG资源,例如,频域位置,时域位置,周期,天线端口信息,调制编码方案等物理层参数,以及定时器配置、混合自动重传请求(hybrid automatic repeat request,HARQ)配置等。本申请实施例并不对完整的CG资源配置参数包括的预配置授权配置的个数进行限定,也不对每个预配置授权配置指示的具体内容进行限定,其可以根据实际场景确定,此处不作赘述。
可选的,在终端设备通过第一配置信息指示配置或重配置CG资源时,可以通过在第一配置信息中是否携带配置指示信息来确定第一配置信息配置或重配置CG资源的资源配置方式。其中,资源配置方式可以是全量配置,也可以是变量配置,此处不对其进行限定。
在本申请实施例的一种可能设计中,第一配置信息通过配置指示信息指示当前的资源配置方式为全量配置,所以,在该种可能设计中,若第一配置信息包括配置指示信息,则终端设备确定第一配置信息配置或重配置CG资源的资源配置方式为全量配置(fullConfig),即可以对终端设备中原有存储的CG资源及其配置信息删除后,再重新配 置CG资源及其配置信息,从而实现终端设备中CG资源及其配置信息的完全更新;相应的,若第一配置信息不包括配置指示信息,则确定第一配置信息配置或重配置CG资源的资源配置方式为变量配置(delta config),这时,终端设备可以根据接收到的第一配置信息,对终端设备内部已有的CG资源及其配置信息进行部分更新。
在本申请实施例的另一种可能设计中,第一配置信息通过配置指示信息指示当前的资源配置方式为变量配置,所以,在该种可能设计中,若第一配置信息包括配置指示信息,则确定资源配置方式为变量配置,即对终端设备内部已有的CG资源及其配置信息进行部分更新,而若第一配置信息不包括配置指示信息,则确定资源配置方式为全量配置,即对终端设备中CG资源及其配置信息进行完全更新。
在本申请实施例的再一种可能设计中,在第一配置信息包括配置指示信息时,可以根据配置指示信息的取值,确定第一配置信息配置或重配置CG资源的资源配置方式。
示例性的,第一指示信息在第一配置信息中可以被赋予不同的取值,例如,fullconfig或deltaconfig,这时,终端设备便可以根据第一指示信息的赋值,确定出资源配置方式。
在本申请的实施例中,网络设备和终端设备约定好一定的规则后,网络设备便可以通过在第一配置信息中是否包含配置指示信息或配置指示信息的具体取值,指示终端设备更新CG资源的方式。
进一步的,在上述各实施例的基础上,图7为本申请实施例提供的资源处理方法实施例四的流程示意图。如图7所示,在本申请的实施例中,在上述S402之后,该资源处理方法还可以包括如下步骤:
S701、进入RRC非激活态。
可选的,在本申请的实施例中,由于第一RRC释放消息用于指示进入RRC非激活态,所以,终端设备在接收到网络设备发送的第一RRC释放消息,对CG资源配置信息进行处理的同时或处理之后,便可以进入RRC非激活态,以便在RRC非激活态下执行数据传输。可以理解的是,终端设备进入RRC非激活态,实际上是由终端设备内部的控制器和处理器统一控制的。
S702、确定在RRC非激活态时的目标数据传输方式。
可选的,处于RRC_INACTIVE态的终端设备可以根据触发条件选择目标数据传输方式。该目标数据传输方式可以是随机接入的小数据传输(Random Access SDT,RA-SDT)或配置授权的小数据传输(configure grant,SDT,CG-SDT)中的任意一种。
示例性的,终端设备进入CG-SDT的触发条件包括:
1、待传输的数据量小于或等于网络配置的数据量阈值;
2、终端设备所选载波及同步信号块(synchronization signal block,SSB)上存在CG资源;
3、检测到的RSRP满足执行CG-SDT的RSRP门限值。
可选的,终端设备进入RA-SDT的触发条件包括:
1、待传输的数据量不大于网络配置的数据量阈值;
2、终端设备所选载波及SSB上不存在CG资源,但存在用于RA-SDT的资源;
3、检测到的RSRP满足执行RA-SDT的RSRP门限值。
可以理解的是,本申请实施例并不限定终端设备选择CG-SDT或RA-SDT的具体触发条件,其可以根据实际情况确定,此处不作赘述。在终端设备既满足选择RA-SDT的触发条件,也满足选择CG-SDT的触发条件时,终端设备可以随机选择,也可以选用默认的数据传输方式,本实施例不对其进行限定。
相应的,在本申请的实施例中,终端设备还可以根据在RRC非激活态时的目标数据传输方式执行不同的操作:
如图7所示,作为一种示例,在目标数据传输方式为随机接入的小数据传输方式时, 该资源处理方法还可以包括S703:
S703、若终端设备中存在用于非激活态数据传输的目标CG资源,则释放目标CG资源和该目标CG资源的配置信息。
在本实施例中,若终端设备选择了利用RA-SDT进行RRC非激活态的数据传输,这时,终端设备内部存储的目标CG资源和该目标CG资源的配置信息便没有用了,为了降低终端设备内部的无用资源占用的空间,终端设备便可以将内部当前存储的目标CG资源和该目标CG资源的配置信息释放掉,以提高终端设备的空间利用率。
作为另一种示例,在目标数据传输方式为配置授权的小数据传输方式时,该资源处理方法还可以包括S704:
S704、根据终端设备中存储的用于非激活态数据传输的目标CG资源执行非激活态数据传输。
在本实施例中,若终端设备选择了利用CG-SDT进行RRC非激活态的数据传输,因而,在终端设备和网络设备之间有数据传输需求时,终端设备便可以利用内部当前存储的目标CG资源进行数据传输。
进一步的,在本申请的实施例中,在S704之后,该资源处理方法还可以包括如下步骤:
S705、接收网络设备发送的RRC消息。
示例性的,终端设备处于RRC非激活态时,其还可以继续接收网络设备发送的RRC消息,进而根据RRC消息的类型,执行不同的操作。
可选的,在RRC消息为用于指示进入RRC非激活态的第二RRC释放消息时,执行S706;在RRC消息为RRC连接恢复消息或第三RRC释放消息或RRC建立消息时,执行S707。其中,第三RRC释放消息用于指示进入RRC空闲态。
S706、根据第二RRC释放消息,确定是否替换或释放目标CG资源及该目标CG资源的配置信息。
作为一种示例,若终端设备在处于RRC非激活态时,接收到指示进入RRC非激活态的第二RRC释放消息时,便可以基于上述图4至图6所示实施例中的方案,确定是否替换或释放目标CG资源及该目标CG资源的配置信息。
关于该步骤的具体实现可以参见上述图4至图6所示实施例中记载的方案,此处不作赘述。
S707、释放目标CG资源及目标CG资源的配置信息。
作为另一种示例,若终端设备在处于RRC非激活态时,接收到的RRC消息为RRC连接恢复消息、指示进入RRC空闲态的第三RRC释放消息、RRC建立消息中的任意一种时,终端设备后续将由当前RRC非激活态进入到对应的状态。
可选的,若终端设备接收到的是RRC连接恢复消息,则终端设备将进入RRC连接态,随便有数据传输需求时会执行连接态的数据传输,通常不利用处于RRC非激活态的目标CG资源,因而,终端设备便可以释放掉终端设备内部当前的目标CG资源及目标CG资源的配置信息。
可选的,若终端设备接收到的是指示进入RRC空闲态的第三RRC释放消息,这时终端设备和网络设备之间会断开连接,并删除掉终端、基站和核心网中原先保留的RRC和AS上下文,因而,终端设备也可以释放掉终端设备内部当前的目标CG资源及目标CG资源的配置信息。
可选的,若终端设备接收到的是RRC建立消息,这时终端设备和网络设备会根据RRC建立消息中的配置信息重新执行RRC建立过程,因而,终端设备中的当前目标CG资源及目标CG资源的配置信息也无实际作用,也需要释放掉当前存储的目标CG资源及目标CG资源的配置信息,以降低终端设备中的资源冗余,提高终端设备中的空间利用率。
可以理解的是,在本申请的实施例中,该第一配置信息包含完整的CG资源配置参数,该完整的CG资源配置参数用于在非激活态数据传输时确定CG资源配置信息。关于完整的CG资源配置参数的具体组成可以参见上述实施例中的记载,此处不作赘述。
在本实施例中,在第一配置信息包含完整的CG资源配置参数时,终端设备才能够在后续根据接收到指示进入非激活态的RRC释放消息确定出执行RRC非激活态数据传输所需的CG资源配置信息,从而确定出所需的目标CG资源。
本申请实施例提供的资源处理方法,终端设备根据接收到的第一RRC释放消息对CG资源配置信息进行处理后,进入RRC非激活态,且确定出在RRC非激活态时的目标数据传输方式,为后续非激活态的数据传输奠定了基础。终端设备根据选择的不同数据传输方式,对终端设备中的CG资源及配置信息执行相应的处理,进一步提高了终端设备内部的空间利用效率。
