- the embodiments of the present invention are not limited to the embodiments of the present invention. For the convenience of description, the following embodiments will be described by taking an eNB as an example.
- the UE When the UE has the requirement to send data, it must first obtain the permission of the eNB, that is, the UE applies to the eNB. Please send a data permission. It should be understood that there are two main ways for the UE to apply for data transmission permission to the eNB. One is that the eNB configures a Scheduling Request (SR) resource for the UE, and the UE requests the data transmission permission from the eNB through the SR resource; The eNB does not configure the SR resource for the UE, but the UE performs the random access procedure first, and then performs the data transmission process.
- SR Scheduling Request
- the eNB After receiving the application data transmission permission of the UE, the eNB performs a resource scheduling decision to determine whether to provide a corresponding service for the UE.
- the smallest unit of eNB resource scheduling is a physical resource block, which is composed of a time domain resource and a frequency domain resource.
- the physical resource block is a time resource of 1 ms in the time domain and a frequency of 12 subcarriers in the frequency domain. Resources.
- the eNB completes data scheduling on the physical resource block. If the eNB decides to provide the service for the UE, the uplink transmission resource is allocated to the UE, and then the uplink access permission (Uplink Grant, referred to as "Uplink Grant" is sent to the UE through the Physical Downlink Control Channel ("PDCCH").
- Uplink Grant Uplink Grant
- the UL grant includes information such as a modulation and coding scheme ("MCS”) and a physical resource block (“PRB").
- MCS modulation and coding scheme
- PRB physical resource block
- the foregoing requesting data transmission permission from the UE to the eNB is only responsible for telling the eNB that the UE has a resource requirement, and how many resources are needed to be notified to the eNB by the subsequent signaling interaction.
- the eNB sends a license according to the application data, and may allocate a small amount of physical resources to the UE, for example, sufficient for the UE to report a power headroom report (PHR) and/or a buffer status report. (Buffer Status Report, referred to as "BSR").
- PHR power headroom report
- BSR Buffer Status Report
- the UE reports the PHR to the eNB according to the physical resource and/or the modulation and coding mode indicated in the UL grant, to inform the eNB of its own power headroom state, or report the eNB to the eNB based on the physical resource and/or modulation and coding mode indicated in the UL grant.
- the BSR is to inform the eNB of the amount of data remaining to be transmitted.
- the eNB allocates a suitable uplink transmission resource to the UE by using the PHR and/or the BSR reported by the UE, and then notifies the UE of the allocated uplink transmission resource by sending the UL grant to the UE. Report data.
- FIG. 1 shows a basic procedure for a UE to report a PHR to an eNB in the current technology.
- the eNB is a base station corresponding to the licensed spectrum cell.
- the UE triggers the PHR. Specifically, for example, because the PHR related timer of the UE times out or the path loss of the UE serving cell exceeds the threshold, the PHR is triggered, and once the UE triggers the PHR, the PHR is always suspended. Hang the state until the corresponding power headroom information is generated.
- the eNB sends a UL grant to the UE through the PDCCH, and the UL grant includes information such as the MCS and the PRB.
- the physical resource indicated by the UL grant is sufficient for the UE to report the power headroom report PHR.
- the physical layer of the UE reads the information in the UL grant, constructs a MAC data unit (Protocol data unit, referred to as “PDU”), and then transmits the MAC PDU to the The physical layer and all the PHRs that have been triggered are deleted.
- PDU MAC data unit
- the physical eNB reports the MAC PDU to the eNB according to the physical resource and the MCS indicated by the UL grant received in the S12, so that the eNB can reasonably allocate the next uplink transmission resource to the UE according to the PHR reported by the UE. .
- the UE needs to report data, and sends a scheduling request SR to the eNB.
- the eNB allocates an uplink transmission resource to the UE according to the PHR received in S14, and specifically, determines the size of the physical resource, the modulation and coding scheme MCS, and the like according to the PHR.
- the eNB sends a UL grant to the UE through the PDCCH, where the UL grant includes indication information indicating the size of the physical resource allocated for the UE in S16 and the modulation and coding manner.
- the UE reports the data to be transmitted to the eNB according to the physical resource indicated by the UL grant received in S17 and the modulation and coding manner.

- LBT Listening Before Listening
- the LBT refers to that the UE needs to perform channel energy detection before transmitting the uplink data, if the detection is performed.
- the channel energy is lower than a certain threshold, the channel is considered to be idle, and the channel can be used to transmit uplink data (also referred to as LBT success); otherwise, the channel is considered to be busy and cannot send uplink data (also referred to as LBT failure).
- the UE cancels the triggered PHR when notifying the physical layer to transmit the MAC PDU. . That is to say, the PHR that has been triggered to be reported has been canceled before the MAC PDU is sent.
- the LAA cell and the licensed spectrum cell are used for carrier aggregation, if the UE chooses to send the MAC PDU through the LAA cell, after receiving the MAC PDU at the physical layer, the LBT process is first performed, and the PHR can be implemented only when the LBT is successful.
- the transmission if the LBT fails, can not report the MAC PDU to the eNB, and at this time, the PHR that has been triggered has been canceled. It should be understood that the transmission of the PHR requires two steps: first, triggering, and secondly, obtaining an uplink transmission resource sufficient to carry the PHR. Therefore, in order to send a new PHR again, it is necessary to wait until the trigger condition of the next PHR is satisfied, and the UL grant indicating the new transmission sent by the eNB is received.
- the existing method for transmitting the PHR reduces the reliability and timeliness of reporting the PHR, thereby affecting the eNB to allocate suitable uplink transmission for the UE. Resources.

- the UE triggers the PHR, and receives the UL grant of the LAA cell, generates the first power headroom information, and notifies the physical layer to the LAA cell.
- the PHR that has been triggered is not cancelled.
- the physical layer contends for the uplink transmission resource before transmitting the first power headroom information, and cancels the PHR that has been triggered when the content is successfully contending for the resource and successfully transmits the first power headroom information. Otherwise, the PHR that has been triggered is retained.

- the LTE system uses the shared channel to transmit data.
- the eNB allocates a UL grant to the UE. Only the UE that receives the UL grant can send the uplink data. If the uplink resource is not received, the UE cannot send the data. .
- For a UE that receives a UL grant sent by an eNB it is necessary to transmit a data packet of a corresponding size according to the amount of data indicated by the eNB.
- one UE may have multiple service transmissions at the same time, correspondingly having multiple logical channels.
- the uplink resources allocated by the eNB to the UE are shared by multiple logical channels, so the uplink data packets sent by the UE usually include data from multiple logical channels.
- the eNB allocates a UL grant, the uplink resource is not accurately allocated to each logical channel.
- the UE obtains the UL grant from the eNB, it needs to determine which logical channel transmits the data by itself. This process is called logical channel priority.
- Level Logical channel prioritization, abbreviated as "LCP").
- the UE When performing LCP processing, the UE needs to consider the priorities of different logical channels, and allocate corresponding uplink transmission resources to different logical channels according to the priority information. Generally, before performing LCP processing, the following types of MACs need to be considered.
- the priority order of the PDUs is as follows:
- BSR MAC control element but does not include padding BSR
- PHR MAC control element including extended PHR and Dual Connectivity PHR
- the LCP priority of the PHR (corresponding to "3) PHR MAC control element" above) is adjusted, for example, when the UL grant of the serving cell is received next time, for example. Improve the PHR in the above five priorities, thus ensuring the transmission reliability of the PHR. If the previous PHR transmission succeeds, the PHR is triggered again within a certain time threshold, and the UL grant of the serving cell is received at the same time, which can lower the priority of the PHR.
- the S170 generates the second power headroom information, including:
- the MAC PDU including the second power headroom information is generated by increasing the priority of the PHR in the priority order 1) to 5) of generating the MAC PDU described above.
- the UE triggers the PHR; in S32, the UE receives the first UL grant delivered by the LAA cell; in S33, the first MAC PDU including the PHR is generated by the MAC entity, and Retaining the PHR that has been triggered; in S34, performing an LBT process, if the LBT process succeeds, that is, competing for resources, sending a first MAC PDU to the LAA cell, and canceling the PHR that has been triggered (not shown in FIG. 4), if If the LBT process fails, the first MAC PDU is not sent, and the PHR that has been triggered is retained.
- S35 it is determined that the LBT process in S34 fails, that is, no resources are contending for the first power headroom information, and the first power headroom information cannot be sent to the LAA cell.
- the PHR that has been triggered is not cancelled, that is, the trigger state of the LBT is reserved;
- the UE receives the second UL grant of the licensed spectrum cell;
- the LCP priority of the PHR is increased, and the transmission resource is preferentially allocated to the PHR;
- a second MAC PDU including a PHR is generated by using a MAC entity, Notifying the physical layer to send the second MAC PDU and retaining the PHR that has been triggered; in S39, transmitting the second MAC PDU to the authorized spectrum cell through the physical layer.
- the PHR that has been triggered may be cancelled.
- the UE transmits data by authorizing the spectrum cell without competing resources. Therefore, when the MAC entity generates a MAC PDU including the PHR, The MAC PDU is sent by the physical layer, and the MAC PDU can be sent successfully. Therefore, in this scenario, when the MAC PDU is generated, when the PHR that has been triggered is canceled, the embodiment of the present invention does not limit this.
- the PHR transmission fails during the current transmission, and after the next time the UL grant of the serving cell is received, the transmission reliability of the PHR can be improved by adjusting the LCP priority of the PHR.
- the primary cell PCell adds a secondary cell SCell to the UE through RRC signaling, for example, an LAA cell
- the Pcell sends an Activation Message (Activation MAC Control Element) to the UE, and the UE receives After the activation message, the LAA cell can be used, wherein after the UE receives the activation message, a PHR is triggered (corresponding to the "4" mentioned in the trigger condition for triggering the PHR described above to activate any one of the allocations.
- the PHR in order to reduce the possibility that the UE transmits the PHR through the LAA cell, when the LAA cell is activated for the UE, the PHR is not triggered.
- the S110 triggers the power headroom report PHR, including:
- the PHR is triggered according to a preset trigger condition, and the preset trigger condition does not include activating an unlicensed spectrum cell with an uplink.
- the primary cell (authorized spectrum cell) configures a secondary cell LAA cell for the UE according to the service situation and the cell condition. Specifically, the primary cell adds one LAA cell to the UE through RRC signaling.
- the RRC signaling includes configuration information of the LAA cell.
- the spectrum cell is authorized to send an Activation MAC Control Element to the UE.
- the UE uses the LAA cell but does not trigger the PHR.
- the primary cell of the UE does not trigger the PHR when the LAA cell is activated, and may reduce the probability of the UE transmitting the PHR through the LAA cell to a certain extent, thereby increasing the probability that the UE transmits the PHR through the authorized spectrum cell. In turn, the transmission reliability of the PHR can be improved.
- the PHR generated by the UE through the MAC entity includes the power headroom PH value of all serving cells (uplink activated cells) of the UE, where the PH value refers to the maximum carrier transmit power of the UE and the carrier power limit is not considered.
- the transmit power calculated without considering the upper limit of the carrier power can be understood as the carrier transmit power calculated by the UE according to the MCS allocated by the eNB and the resource block size.
- the carrier transmit power may be the transmit power of the PUCCH data, or the transmit power of the PUSCH data, or the transmit power of the data transmitted simultaneously on the PUCCH and the PUSCH.
- the PH may be a negative value, that is, the UE does not consider the carrier power upper limit and the calculated transmit power is greater than the actual maximum carrier transmit power. In this case, the UE data will be difficult to transmit successfully, which in turn affects data scheduling.
- the PH of a cell refers to the power headroom of the cell at the time of data transmission of the PUSCH or the PUCCH, where the data transmission time generally refers to the fourth frame after the frame where the UE receives the UL grant, as shown in FIG. 6. Show.
- the PH value is calculated in advance before the data transmission time, and the specific advance depends on the capability of the UE.
- the UE receives the UL grant from the eNB in subframe 1, and performs new data transmission in subframe 5.
- the MAC entity of the UE constructs a MAC PDU including a PHR MAC Control Element.
- the PH value reported in the PHR MAC Control Element is the power headroom of the UE at the subframe 5.
- the UE For any cell, if the UE sends PUSCH data, it will report a true type 1 PH value. Otherwise, a virtual type 1 PH value is reported. It should be understood that the type 1 PH of a cell refers to the power margin of the cell at the time of data transmission of the PUSCH or PUCCH. If the UE is configured to transmit the PUSCH and the PUCCH at the same time, the UE reports the type 2 PH of the primary cell in addition to the type 1 PH of the serving cell. If there is a PUCCH data transmission, the UE reports a true type 2 PH. If there is no PUCCH data transmission, the UE reports a virtual type 2 PH. It should be understood that the type 2 PH of the primary cell refers to the primary cell in the PUCCH and the PUSCH. The power headroom of the data transmission time.
- the LBT process of the LAA cell fails, data cannot be transmitted. Even if the UE has data to transmit in the LAA cell, when the LBT is actually performed during the transmission process, the resource may fail to be competed, and the data cannot be transmitted in practice. Therefore, according to the roots of the prior art It is unreasonable to determine the PH value of the LAA cell according to the data transmission requirement of the UE, which may cause the PH value to be inconsistent with the actual process, which may cause the next uplink transmission resource allocated by the eNB to be too small.

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
还应理解,在本发明实施例中,用户设备(User Equipment,简称为“UE”)也可称之为终端、移动台(Mobile Station,简称为“MS”)、移动终端(Mobile Terminal)等,该用户设备可以经无线接入网(Radio Access Network,简称为“RAN”)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等,例如,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。
为了便于理解和描述本发明实施例提供的上行数据的传输方法和用户设备,下面首先介绍一下本发明实施例的应用场景。
在本发明实施例中,基站可以是GSM中的基站(Base Transceiver Station,简称为“BTS”),也可以是WCDMA中的基站(NodeB,简称为“NB”),还可以是LTE中的演进型基站(Evolutional Node B,简称为“eNB或e-NodeB”),本发明实施例并不限定,但为描述方便,下述实施例将以eNB为例进行说明。
当UE有发送数据的需求时,须先得到eNB的许可,即UE向eNB申
请数据发送许可。应理解,UE向eNB申请数据发送许可主要有两种方式:一种是eNB为UE配置调度请求(Scheduling Request,简称为“SR”)资源,UE通过SR资源向eNB申请数据发送许可;另一种方式eNB不为UE配置SR资源,而是UE先进行随机接入过程,再进行数据发送过程。
eNB收到UE的申请数据发送许可后,进行资源调度决策,决定是否为该UE提供相应的服务。eNB资源调度的最小单元是物理资源块,物理资源块是由时域资源和频域资源共同构成的,物理资源块在时域上为1ms的时间资源,在频域上为12个子载波的频率资源。eNB在物理资源块上完成数据调度。如果eNB决定为该UE提供服务,则为该UE分配上行传输资源,然后通过物理下行控制信道(Physical Downlink Control Channel,简称为“PDCCH”)向UE下发上行接入允许(Uplink Grant,简称为“UL grant”),该UL grant包括调制编码方式(Modulation and coding Scheme,简称为“MCS”)、物理资源块(physical resource block,简称为“PRB”)等信息,该UL grant告诉该UE可以在哪个时间哪个载波上传输数据,以及采用的调制编码方案,以便UE准确地传输数据。
应理解,上述UE向eNB申请数据发送许可只负责告诉eNB该UE有资源需求,而具体需要多少资源可以由之后的信令交互告诉eNB。对应地,eNB根据该申请数据发送许可,可以为该UE先分配一少部分物理资源,例如足够供UE上报功率余量报告(Power headroom report,简称为“PHR”)和/或缓冲区状态报告(Buffer Status Report,简称为“BSR”)。
然后,UE根据UL grant中指示的物理资源和/或调制编码方式向eNB上报PHR,以告诉eNB自己的功率余量状态,或者基于UL grant中指示的物理资源和/或调制编码方式向eNB上报BSR,以告诉eNB自己剩余待传输的数据量。
如果UE有数据发送,eNB就以UE上报的PHR和/或BSR作为参考,为该UE分配合适的上行传输资源,然后通过下发UL grant告知给该UE为其分配的上行传输资源,以便UE上报数据。
图1示出了在当前技术中,UE向eNB上报PHR的基本流程,在该示例中,该eNB为授权频谱小区所对应的基站。在S11中,UE触发PHR。具体地,例如由于UE的PHR相关定时器超时或该UE服务小区的路损变化超过了门限,从而触发了PHR,UE一旦触发PHR,该PHR就会一直处于悬
挂状态,直到生成对应的功率余量信息。在S12中,eNB通过PDCCH向UE发送UL grant,该UL grant包括MCS、PRB等信息,应理解,在该步骤中,该UL grant所指示的物理资源足够UE上报功率余量报告PHR。在S13中,UE的物理层在成功接收到UL grant后,读取UL grant中的信息,构造包括PHR的MAC协议数据单元(Protocol data unit,简称为“PDU”),然后将MAC PDU传输到物理层,并取消所有已经触发的PHR,应理解,读取UL grant中的信息,具体读取UL grant中携带的指示MCS和物理资源的信息。在S14中,通过物理层根据S12中接收到的UL grant所指示的物理资源和MCS,向eNB上报MAC PDU,从而使得eNB可以根据UE上报的PHR来为该UE合理地分配下一次上行传输资源。在S15中,例如UE需要上报数据,向eNB发送调度请求SR。在S16中,eNB根据在S14中接收到PHR为该UE分配上行传输资源,具体地,根据PHR确定物理资源的大小以及调制编码方式MCS等。在S17中,eNB通过PDCCH向UE发送UL grant,该UL grant包括用于指示在S16中为该UE分配的物理资源的大小以及调制编码方式的指示信息。在S18中,该UE根据在S17中接收的UL grant所指示的物理资源以及调制编码方式向eNB上报所需传输的数据。
由上可知,在当前技术中,当UE的MAC实体生成包括PHR的MAC PDU后,就取消了所有已经触发的PHR。
目前,第三代合作伙伴计划(3rd Generation Partnership Project,简称为“3GPP”)引入了授权辅助接入(License Assisted Access,简称为“LAA”)小区,并将LAA小区与授权频谱小区做载波聚合(Carrier Aggregation,简称为“CA”),应理解,LAA小区与授权频谱小区做载波聚合,只有授权频谱小区可以作为主小区PCell,LAA小区只能作为辅助小区(Secondary Cell,简称为“SCell”)。应理解,载波聚合是LTE/LTE-A中的一项技术,UE可以同时与多个服务小区进行数据传输,任意两个小区之间的连接可以认为是理想的,即传输时延可以忽略。在本发明实施例中,多个服务小区包括授权频谱小区和LAA小区。
在LAA小区与授权频谱小区作载波聚合的场景下,UE的服务小区有多个,其中包括LAA小区,则当UE触发了PHR后,后续通过该UE的多个服务小区中的哪个服务小区来上报PHR,取决于多个服务小区中哪个小区最先下发了UL grant,假设是UE的多个服务小区中的LAA小区最先下发了
UL grant,则该UE通过LAA小区向eNB上报PHR。
应理解,UE通过LAA小区发送上行数据之前,需要先进行说前先听(Listen before talk,简称为“LBT”)过程,LBT指的是UE在发送上行数据前需要进行信道能量检测,如果检测到信道能量低于某个门限,则认为信道空闲,可以占用信道发送上行数据(也可称之为LBT成功);否则,认为信道忙碌,无法发送上行数据(也可称之为LBT失败)。
结合上述图1可知,当前技术中,在UE向eNB上报PHR的过程中,UE通过MAC实体构造包括PHR的MAC PDU完成后,在通知物理层传输该MAC PDU时,就取消了已经触发的PHR。也就是说,在发送MAC PDU之前,已经取消了已经触发上报的PHR。而在LAA小区与授权频谱小区作载波聚合的场景下,如果UE选择通过LAA小区发送MAC PDU,在物理层收到MAC PDU后,首先进行LBT过程,只有在LBT成功的情况下才可以实现PHR的发送,如果LBT失败了,就不能向eNB上报MAC PDU了,而此时,已经取消了已经触发的PHR。应理解,PHR的发送需要有两个步骤:首先是触发,其次获得足够承载PHR的上行传输资源。因此,要想再次发送新的PHR,首先要等到下次的PHR的触发条件满足,并且接收到eNB下发的指示新传的UL grant,才可以实现。可知,在UE的服务小区为LAA小区与授权频谱小区载波聚合的场景下,现有的发送PHR的方法,降低了上报PHR的可靠性和及时性,从而影响了eNB为UE分配合适的上行传输资源。
针对上述技术问题,本发明实施例提出一种上行数据的传输方法和用户设备,能够有效实现PHR(或者BSR)的及时上报。
图2示出了根据本发明实施例提供的一种上行数据的传输方法100,具体地,该方法100由用户设备UE执行,该方法100包括:
S110,触发功率余量报告PHR;
应理解,当UE触发PHR后,PHR会一直处于挂起的状态,也可以理解为PHR处于被发送的状态,直到该已经触发的PHR被取消为止。换句话说,一旦触发了PHR,这时如果UE获取到UL grant,UE就可以向eNB发送功率余量信息。如果没有触发PHR,即使UE获取了UL grant,UE也不会向eNB发送功率余量信息。
具体地,UE根据预设的触发条件触发PHR,具体地,该触发条件可以
为以下条件中的任何一种或多种:
1)禁止PHR定时器超时,并且至少一个激活服务小区在初传数据时路损变化超过预设门限;
2)周期PHR定时器超时;
3)上层配置或重配置PHR功能
4)激活任意一个配有上行的SCell;
5)禁止定时器超时,并且至少一个激活服务小区在初传数据时所做的功率回退超过一定门限。
应理解,上面罗列触发条件仅为示例而非限定。
S120,接收第一服务小区的第一上行调度授权UL grant,该第一服务小区为非授权频谱小区;
具体地,该UL grant包括调制编码方式(Modulation and coding Scheme,简称为“MCS”)、物理资源块(physical resource block,简称为“PRB”)等信息,该UL grant用于告知UE可以在哪个物理资源块上传输数据,以及采用的调制编码方案,以便UE准确地传输上行数据。
可选地,该第一UL grant可以由第一服务小区向该UE发送,也可以由另一个服务小区向该UE发送,例如该另一个服务小区为该UE的主小区,该第一服务小区为该UE的辅小区。
具体地,该UL grant通过物理下行控制信道(Physical Downlink Control Channel,简称为“PDCCH”)向UE下发。
应理解,在本发明实施例中,非授权频谱小区指的使用的频谱资源为非授权频谱的小区。具体地,非授权频谱小区具体地为授权辅助接入(License Assisted Access,简称为“LAA”),这时该LAA小区与授权频谱小区作载波聚合CA,且该LAA小区为辅小区。该非授权频谱小区也可以为能够独立作为UE的服务小区的小区,本发明实施例对此不作限定。
S130,根据该已经触发的PHR以及该第一UL grant,生成第一功率余量信息,并保留该已经触发的PHR;
具体地,由MAC实体(即MAC层)生成该第一功率余量信息,该第一功率余量信息中携带了UE的已经激活上行的所有服务小区的功率余量PH值。
应理解,保留该已经触发的PHR指的是,该PHR还处于挂起状态,或
者处于待发送状态。
需要说明的是,在本发明实施例中,在生成第一功率余量信息后,并不像现有流程中一样取消已经触发的PHR,而是继续保留已经触发的PHR。
S140,根据该第一UL grant,向该第一服务小区发送该第一功率余量信息。
具体地,根据该第一UL grant所指示的调制编码方式MCS和物理资源等信息,向该第一服务小区发送该第一功率余量信息。
应理解,在本发明实施例中,向该第一服务小区发送该第一功率余量信息,可以是向该第一服务小区直接发送该第一功率余量信息;也可以是向该第一服务小区发送包括该第一功率余量信息的数据包或者报文,具体地,例如,首先MAC层根据该第一功率余量信息构造PHR MAC CE,然后将该PHR MAC CE组装到MAC PDU中,然后通过物理层向第一服务小区发送该MAC PDU,本发明实施例对发送第一功率余量信息的具体手段不作限定。
可选地,在本发明实施例中,S140根据该第一UL grant,向该第一服务小区发送该第一功率余量信息,包括:
S140A,通过MAC实体生成第一MAC协议数据单元(Protocol Data Unit,简称为“PDU”),该第一MAC PDU包括该第一功率余量信息;
具体地,MAC实体根据第一UL grant所指示的MCS和物理资源信息,生成该第一MAC PDU。
S140B,根据该第一UL grant,向该第一服务小区发送该第一MAC PDU。
应理解,该第一MAC PDU中除了第一功率余量信息,还可以包括其他相关信息,确定MAC PDU的过程为现有技术,这里不再详述。
还应理解,在S140中向该第一服务小区发送该第一功率余量信息,具体指的是,向该第一服务小区对应的eNB发送该第一功率余量信息,或者可以表述为通过该第一服务小区向该第一服务小区对应的eNB发送该第一功率余量信息。
可选地,在本发明实施例中,当确定成功发送该第一功率余量信息后,可以取消已经触发的PHR。
由上可知,本发明实施例提供的传输方法,在生成要上报的功率余量信息之后,并不像现有技术中一样马上取消已经触发的PHR,而是保留已经触发的PHR(也可称之为悬挂已经触发的PHR),然后向eNB发送生成的功率
余量信息,确定发送成功后,可以取消已经触发的PHR。因此,本发明实施例提供的方法,相对于现有技术,一定程度上能够保证PHR的及时传输,能够有效提高PHR的传输可靠性。
还应理解,在UE的服务小区包括授权频谱小区和LAA小区的情形下,相当于是授权频谱小区和LAA小区作载波聚合CA,其中,只有授权频谱小区可以作为UE的主小区(Primary Cell,简称为“PCell”),假设UE的服务小区中的一个授权频谱小区作为该UE的PCell,则其余服务小区为该UE的辅小区(Secondary Cell,简称为“SCell”),应理解,LAA小区只能作为该UE的SCell。还应理解,PCell可以通过无线资源控制(Radio Resource Control,简称为“RRC”)信令为该UE添加一个SCell,例如添加一个LAA小区作为该UE的SCell,该RRC信令包括LAA小区的配置信息,UE通过接收PCell下发的激活消息(Activation MAC Control Element),就可以使用该作为SCell的LAA小区了。
应理解,当UE在LAA小区中发送上行数据之前,需要竞争上行传输资源,具体地,通过说前先听LBT过程竞争资源,只有在成功竞争到资源后才,才发送数据,否则,数据无法发送。
可选地,在本发明实施例中,S140根据该第一UL grant,向该第一服务小区发送该第一功率余量信息,包括:
S141,通过先听后说LBT过程竞争第一资源,当竞争该第一资源成功后,基于该第一资源向该第一服务小区发送该第一功率余量信息,并取消该已经触发的PHR,该第一资源为该第一UL grant指示的上行传输资源。
应理解,取消已经触发的PHR,指的是PHR不再处于挂起或者待发送的状态,即使这时UE获取了UL grant,也不会执行发送PHR(对应于发送功率余量信息)的动作。
应理解,LBT是指对信道进行能量检测,能量低于一定门限认为信道空闲,高于门限,信道被占用。目前LBT过程主要有以下几种:
1)没有回退的LBT,即信道能量检测低于门限,不进行回退继续能量检测。
2)回退的LBT,即信道能量检测低于门限,随机产生一个值x,当信道检测空闲的次数减为0后,重新开始信道能量检测。
3)在固定窗口内回退的信道能量检测,即信道能量检测低于门限,在
一个时间窗口内做回退的信道能量检测。
4)可变窗口的回退LBT,即信道能量检测低于门限,在一个可变时间窗口内做回退的信道能量检测。
应理解,物理层在发送数据之前也有可能竞争资源失败,即LBT过程失败,这种情况下,不发送第一功率余量信息,并且不取消已经触发的PHR,即继续保留已经触发的PHR。
可选地,在本发明实施例中,该方法100还包括:
S150,当竞争该第一资源失败后,不向该第一服务小区发送该第一功率余量信息,并继续保留该已经触发的PHR。
上文已经提及,UE实现上报PHR,需要满足两个条件,一是触发PHR,二是接收到eNB下发的UL grant。应理解,在S150描述的实施例中,本次传输过程中没有竞争到资源,无法成功发送生成的第一功率余量信息,但是由于保留了已经触发的PHR,使得下次接收到eNB下发的UL grant后,就可再次执行上报PHR,而不必等待下一次的PHR的触发条件满足时重新触发PHR。
可选地,在本发明实施例中,在竞争该第一资源失败的情况下,即在不发送该第一功率余量信息,并继续保留已经触发的PHR的情况下,该方法100还包括:
S160,接收第二服务小区的第二UL grant;
S170,根据该第二UL grant和该已经触发的PHR,生成第二功率余量信息,并继续保留该已经触发的PHR;
S180,根据该第二UL grant,向该第二服务小区发送该第二功率余量信息,其中,该第二服务小区为非授权频谱小区或授权频谱小区。
具体地,如图3所示,在S21中,UE触发PHR;在S22中,UE接收LAA小区下发的第一UL grant;在S23中,通过MAC实体生成包括PHR的第一MAC PDU,并保留已经触发的PHR;在S24中,进行LBT过程,如果LBT过程成功,即竞争到资源,则向LAA小区发送第一MAC PDU,并取消已经触发的PHR(图3中未示出),如果LBT过程失败,则不发送第一MAC PDU,并保留已经触发的PHR;在S25中,确定S24中的LBT过程失败,即没有竞争到资源,无法向LAA小区发送该第一功率余量信息,不取消已经触发的PHR,即保留LBT的触发状态;在26中,UE再次接收到第
二服务小区(图3中以授权频谱小区为例示出)发送的第二UL grant;在S27中,通过MAC实体生成包括PHR的第二MAC PDU,并保留已经触发的PHR;在S28中,通过物理层向第二服务小区发送该第二MAC PDU,该第二服务小区可能是LAA小区,也有可能是授权频谱小区,如果该第二服务小区为LAA小区,则返回到步骤S24,如果该第二服务小区为授权频谱小区,则按照现有的流程,将生成的第二MAC PDU通过物理层发送到该第二服务小区。
应理解,在本发明实施例中,第二服务小区与第一服务小区可以为同一个服务小区,也可以为不同的服务小区,本发明实施例对此不作限定。
上述可知,在本发明实施例中,在UE的服务小区包括LAA小区的场景下,UE触发PHR,并接收到LAA小区的UL grant,生成第一功率余量信息,在通知物理层向LAA小区发送该第一功率余量信息时,并不取消已经触发的PHR。物理层在发送第一功率余量信息之前竞争上行传输资源,在竞争到资源并成功发送第一功率余量信息时,才取消已经触发的PHR,否则继续保留已经触发的PHR。在发送失败,保留已经触发的PHR的情况下,当再次接收到UL grant时,可以再次执行PHR的上报,而无需像传统技术中一样需再次等待PHR的触发条件满足,且接收到UL grant之后才可以上报PHR。
因此,在本发明实施例中,在未确定成功发送PHR的情况下,并不取消已经触发的PHR,即维持保留已经触发的PHR,直到发送成功之后,才取消已经触发的PHR,相对于现有技术能够有效保证PHR的传输可靠性和及时性。
应理解,LTE***中采用共享信道的方式发送数据,对于上行数据,由eNB为UE分配UL grant,只有收到UL grant的UE才能发送上行数据,如果没有收到上行资源,UE就不能发送数据。对于接收到eNB发送的UL grant的UE,必须按照eNB指示的数据量,发送相应尺寸的数据包。通常,一个UE可能同时有多个业务传输,对应地有多个逻辑信道。eNB向UE分配的上行资源是由多个逻辑信道共享的,所以UE发送的上行数据包通常包含了来自多个逻辑信道的数据。但是eNB分配UL grant时,并不会将上行资源精确地分配到各个逻辑信道去,通常,UE从eNB处获得UL grant后,需要自行确定哪个逻辑信道传输多少数据,这个过程称为逻辑信道优先级
(Logical channel prioritization,简称为“LCP”)。
UE在进行LCP处理时,需考虑不同逻辑信道的优先级,根据该优先级信息,为不同的逻辑信道分配对应的上行传输资源,通常,在进行LCP处理前,还需考虑以下几种生成MAC PDU的优先级顺序依次如下:
1)UL-CCCH数据或包括C-RNTI的MAC control element;
2)BSR MAC control element,但是不包括padding BSR;
3)PHR MAC control element(包括extended PHR和Dual Connectivity PHR);
4)逻辑信道数据,但是除了UL-CCCH数据;
5)Padding BSR。
在本发明实施例中,如果前一次PHR发送失败,那么在下一次接收到服务小区的UL grant时,通过调整PHR(对应于上文中的“3)PHR MAC control element”)的LCP优先级,例如提高PHR在上述5种优先级,从而保证PHR的传输可靠性。如果前一次PHR发送成功,那么在一定时间门限内又触发了PHR,同时又收到服务小区的UL grant,可以降低PHR的优先级。
可选地,在本发明实施例中,S170生成第二功率余量信息,包括:
S171,通过提高该已经触发的PHR的优先级,生成该第二功率余量信息。
具体地,通过提高PHR在上文所述的生成MAC PDU的优先级顺序1)至5)中的优先级,生成包括该第二功率余量信息的MAC PDU。
具体地,如图4所示,在S31中,UE触发PHR;在S32中,UE接收LAA小区下发的第一UL grant;在S33中,通过MAC实体生成包括PHR的第一MAC PDU,并保留已经触发的PHR;在S34中,进行LBT过程,如果LBT过程成功,即竞争到资源,则向LAA小区发送第一MAC PDU,并取消已经触发的PHR(图4中未示出),如果LBT过程失败,则不发送第一MAC PDU,并保留已经触发的PHR;在S35中,确定S34中的LBT过程失败,即没有竞争到资源,无法向LAA小区发送该第一功率余量信息,不取消已经触发的PHR,即保留LBT的触发状态;在S36中,UE接收到授权频谱小区的第二UL grant;在S37中,调高PHR的LCP优先级,优先给PHR分配传输资源;在S38中,通过MAC实体生成包括PHR的第二MAC PDU,
通知物理层发送该第二MAC PDU,并保留已经触发的PHR;在S39中,通过物理层向授权频谱小区发送该第二MAC PDU。
应理解,通过S37中的调高PHR的LCP优先级,优先给PHR分配传输资源,能够提高传输PHR的及时性。
可选地,在S38中,生成第二MAC PDU后,就可以取消已经触发的PHR了,应理解,UE通过授权频谱小区传输数据,无需竞争资源,因此,当MAC实体生成包括PHR的MAC PDU,并通过物理层发送该MAC PDU,通常都可以发送成功,因此,在这种场景下,当生成MAC PDU之后,何时取消已经触发的PHR均可,本发明实施例对此不作限定。
因此,在本发明实施例中,当前一次传输过程中PHR发送失败,在下一次接收到服务小区的UL grant后,通过调整PHR的LCP优先级,从而能够提高PHR的传输可靠性。
传统技术中,当主小区PCell通过RRC信令为UE添加一个辅小区SCell,例如为LAA小区,当UE要使用该LAA小区时,Pcell会给UE发送一个激活消息(Activation MAC Control Element),UE接收到该激活消息后,就可以使用LAA小区了,其中,在UE接收到该激活消息后,会触发一个PHR(对应于上文中描述触发PHR的触发条件中提及的“4)激活任意一个配有上行的SCell”)。
在本发明实施例中,为了降低UE通过LAA小区发送PHR的可能性,当为UE激活LAA小区时,并不触发PHR。
可选地,在本发明实施例中,S110触发功率余量报告PHR,包括:
根据预设触发条件,触发该PHR,该预设触发条件不包括激活配有上行的非授权频谱小区。
具体地,如图5所示,在S41中,主小区(授权频谱小区)根据业务情况和小区情况给UE配置一个辅小区LAA小区,具体地,主小区通过RRC信令为UE添加一个LAA小区,RRC信令中包含LAA小区的配置信息。在S42中,授权频谱小区给UE发送激活消息(Activation MAC Control Element);在S43中,UE收到该Activation MAC Control Element后,使用LAA小区,但不触发PHR。
应理解,在S43之后,如果LAA小区通过PDCCH给UE下发UL grant,除非还有其他条件触发了PHR,否则UE就不会向LAA小区上报PHR。
因此,在本发明实施例中,UE的主小区在激活LAA小区时,不触发PHR,在一定程度上可以降低UE通过LAA小区传输PHR的几率,从而可以增加UE通过授权频谱小区传输PHR的几率,进而能够提高PHR的传输可靠性。
应理解,UE通过MAC实体生成的PHR包括UE的所有服务小区(上行激活的小区)的功率余量PH值,其中PH值是指UE的最大载波发射功率与不考虑载波功率上限所计算出的发射功率之差。不考虑载波功率上限所计算出的发射功率可以理解为UE根据eNB所分配的MCS、资源块大小所计算出的载波发射功率。载波发射功率可以是传输PUCCH数据的发射功率,也可以是传输PUSCH数据的发射功率,还可以是在PUCCH和PUSCH上同时传输数据的发射功率。PH可能为负值,即UE不考虑载波功率上限所计算出的发射功率大于本身的实际最大载波发送功率,这种情形下,UE的数据将难以发送成功,继而影响数据调度。
一个小区的PH指的是该小区在PUSCH或PUCCH的数据发送时刻的功率余量,其中,数据发送时刻通常指的是UE接收UL grant的时刻所在帧之后的第四个帧,如图6所示。这个PH值是在数据发送时刻前提前计算好的,具体提前多少取决于UE的能力,如图6所示,UE在子帧1收到来自eNB的UL grant,在子帧5进行新数据传输,在子帧2、3、4,UE的MAC实体进行构造包含PHR MAC Control Element的MAC PDU。其中,PHR MAC Control Element中上报的PH值是UE在子帧5时的功率余量。对于任何一个小区,UE如果有PUSCH数据发送,就会上报一个真实的type 1PH值,否则,上报一个虚拟的type 1PH值。应理解,一个小区的type 1PH指的是,是该小区在PUSCH或PUCCH的数据发送时刻的功率余量。如果UE配置了同时传输PUSCH和PUCCH,那么UE除了上报所有配有上行的服务小区的type 1PH,还要上报主小区的type 2PH。如果有PUCCH数据传输,则UE就上报一个真实的type 2PH,如果没有PUCCH数据传输,则UE就上报一个虚拟的type 2PH,应理解,主小区的type 2PH指的是该主小区在PUCCH和PUSCH的数据发送时刻的功率余量。
但是对于LAA小区,如果LAA小区的LBT过程失败,就无法传输数据。即使UE在LAA小区有数据要传输,但实际传输过程中进行LBT时,可能竞争资源失败,导致实际中无法传输数据。因此,按照现有技术中的根
据UE的数据传输需求来确定LAA小区的PH值是不合理的,可能导致PH值与实际过程不相符,进而可能会造成eNB下一次分配的上行传输资源过小等问题。
针对上述问题,在本发明实施例中,在生成PHR时,将LAA小区的PH值都按虚拟值填充。
可选地,在本发明实施例中,该方法100由用户设备UE执行,该UE的服务小区包括授权频谱小区和非授权频谱小区,该服务小区均为已经激活的配有上行的小区,其中,S140生成第一功率余量信息,包括:
生成该第一功率余量信息,该第一功率余量信息包括该服务小区中各个小区的功率余量值,其中,该非授权频谱小区的功率余量值为虚拟值。
具体地,图7示出了包括了M+N个小区的PH值的PHR的示意图,其中,M个授权频谱小区,N个LAA小区,UE配置了同时传输PUSCH和PUCCH的功能,第一行中的c1至c7为服务小区索引(小区Index),P用于指示是否进行功率回退,V用于指示PH值为真实的还是虚拟的;R表示保留位;第二行至第五行表示主小区的PH上报,其中第二行和第三行表示主小区的type 2PH上报,其中,第二行中的PH(Type 2,主小区)表示的是UE的主小区的type 2PH值,其中Type2是配置同时PUSCH和PUCCH传输的情况下,UE根据PUSCH和PUCCH分配的资源所计算出的PH值。第三行中的Pcmax,c指的是主小区在配置了同时传输PUSCH和PUCCH的情况下的最大载波发射功率。第四行和第五行表示主小区的type 1PH上报。如图5所示,在本发明实施例中,对于LAA小区,对应图5中的第10行至13行,UE无论在没有PUSCH数据情况下,或者有PUSCH数据上报的情况下,该LAA小区的type 1PH值始终以虚拟值填充。对于作为辅助小区的授权频谱小区,还是根据是否有PUSCH传输,确定type 1PH值,如果有PUSCH传输,那么上报一个真实的type 1PH;如果没有PUSCH传输,那么上报一个虚拟的type 1PH。
应理解,本发明实施例中涉及的PHR上报格式只是其中的一种表示方式,不做表示方式限制,包括最终内容即可。
应理解,本发明实施例中涉及的PH值为虚拟值,该虚拟值指的是PH值是在没有PUSCH传输的情况下,按照协议规定的参考格式计算的PH值。
因此,在本发明实施例中,对于授权频谱小区,在PHR MAC Control
Element中上报的PH值是真实的,对于配有上行的激活LAA小区,在PHR MAC Control Element中上报的PH值是按虚拟值填充,能够一定程度上避免eNB分配的上行传输资源不当。
应理解,本发明实施例中的授权频谱小区也可称之为Normal小区。
图8示出了根据本发明另一实施例提供的一种上行数据的传输方法200,例如,该传输方法200可以由用户设备UE执行,该方法200包括:
S210,该UE触发功率余量报告PHR;
S220,接收第一服务小区的第一上行调度授权UL grant;
具体地,该UL grant包括调制编码方式(Modulation and coding Scheme,简称为“MCS”)、物理资源块(physical resource block,简称为“PRB”)等信息,该UL grant用于告知UE可以在哪个物理资源块上传输数据,以及采用的调制编码方案,以便UE准确地传输上行数据。
可选地,该第一UL grant可以由第一服务小区向该UE发送,也可以由另一个服务小区向该UE发送,例如该另一个服务小区为该UE的主小区,该第一服务小区为该UE的辅小区。
具体地,该UL grant通过物理下行控制信道(Physical Downlink Control Channel,简称为“PDCCH”)向UE下发。
S230,当该第一服务小区为非授权频谱小区时,保留该已经触发的PHR;
具体地,当该第一服务小区为非授权频谱小区时,不生成功率余量信息,并保留已经触发的PHR。
S240,当该第一服务小区为授权频谱小区时,根据该已经触发的PHR以及该第一UL grant,生成第一功率余量信息,并根据该第一UL grant向该第一服务小区发送该第一功率余量信息,并取消该已经触发的PHR。
因此,在本发明实施例中,当接收到授权辅助接入小区的UL grant时,不向该非授权频谱小区发送PHR,只有当接收到授权频谱小区的UL grant时,才向该授权频谱小区发送PHR,能够避免通过非授权频谱小区发送PHR存在的传输可靠性差的问题。
应理解,在本发明实施例中,在S230中,可以根据传统流程来执行,本发明实施例对此不作限定。
应理解,该UE根据预设的触发条件触发PHR,具体地,该触发条件可以为以下条件中的任何一种或多种:
1)禁止PHR定时器超时,并且至少一个激活服务小区在初传数据时路损变化超过预设门限;
2)周期PHR定时器超时;
3)上层配置或重配置PHR功能
4)激活任意一个配有上行的SCell;
5)禁止定时器超时,并且至少一个激活服务小区在初传数据时所做的功率回退超过一定门限。
应理解,上面罗列触发条件仅为示例而非限定。
具体地,如图9所示,在S51中,UE触发PHR。在S52中,相比于授权频谱小区,LAA Cell先给UE下发了第一UL grant。在S53中,通过MAC实体构造不包括PHR的第一MAC PDU,并通知物理层传输该第一MACPDU,并保留已经触发的PHR。在S54中,物理层通过LBT过程发送该MACPDU,具体过程与上文结合图3描述的S24与S25。在S55中,接收来自授权频谱小区的第二UL grant;在S56中,通过MAC实体构造包括PHR的第二MAC PDU,将第二MAC PDU传输到物理层,并取消已经触发的PHR;在S57中,通过授权频谱小区向eNB发送包括PHR的第二MAC PDU。
因此,在本发明实施例中,避免不通过LAA小区上报PHR,只有接收到授权频谱小区下发的UL grant之后,才会生成对应的PHR,通过该授权频谱小区上报PHR,能够有效提高上报PHR的及时性和可靠性。
上文已经提及,UE实现上报PHR,需要满足两个条件,一是触发PHR(换句话说,PHR的触发状态有效),二是接收到eNB下发的UL grant。应理解,在S220描述的实施例中,不向第一服务小区发送PHR,但是由于保留了已经触发的PHR,使得下次接收到eNB下发的UL grant后,就可再次执行上报PHR,而不必等待下一次的PHR的触发条件的满足。
可选地,在本发明实施例中,当该第一服务小区为非授权频谱小区时,不生成功率余量信息。
可选地,在本发明实施例中,在该第一服务小区为非授权频谱小区,不向该第一服务小区发送PHR,并保留已经触发的PHR的情况下,该方法200还包括:
S250,接收第二服务小区的第二UL grant;
S260,当该第二服务小区为授权频谱小区时,根据该已经触发的PHR
以及该第二UL grant,生成第二功率余量信息,并根据该第二UL grant,向该第二服务小区发送该第二功率余量信息,并该已经触发的PHR。
因此,在本发明实施例中,在未确定成功发送PHR的情况下,并不取消已经触发的PHR,即维持保留已经触发的PHR,直到发送成功之后,才取消已经触发的PHR,相对于现有技术能够有效保证PHR的传输可靠性和及时性。
可选地,在本发明实施例中,S260生成第二功率余量信息,包括:
通过提高该已经触发的PHR的优先级,生成该第二功率余量信息。
具体地,通过提高PHR在上文所述的生成MAC PDU的优先级顺序1)至5)中的优先级,生成包括该第二功率余量信息的MAC PDU。
具体地,如上文结合图4的描述,为了简洁,这里不再详述。
因此,在本发明实施例中,当前一次传输过程中PHR发送失败,在下一次接收到服务小区的UL grant后,通过调整PHR的LCP优先级,从而能够提高PHR的传输可靠性。
传统技术中,当主小区PCell通过RRC信令为UE添加一个辅小区SCell,例如为LAA小区,当UE要使用该LAA小区时,Pcell会给UE发送一个激活消息(Activation MAC Control Element),UE接收到该激活消息后,就可以使用LAA小区了,其中,在UE接收到该激活消息后,会触发一个PHR(对应于上文中描述触发PHR的触发条件中提及的“4)激活任意一个配有上行的SCell”)。
在本发明实施例中,为了降低UE通过LAA小区发送PHR的可能性,当为UE激活LAA小区时,并不触发PHR。
可选地,在本发明实施例中,S210触发功率余量报告PHR,包括:
根据预设触发条件,触发该PHR,该预设触发条件不包括激活配有上行的非授权频谱小区。
具体地,如上文结合图5所述,这里不再详述。
因此,在本发明实施例中,UE的主小区在激活LAA小区时,不触发PHR,在一定程度上可以降低UE通过LAA小区传输PHR的几率,从而可以增加UE通过授权频谱小区传输PHR的几率,进而能够提高PHR的传输可靠性。
可选地,在本发明实施例中,该方法由用户设备UE执行,该UE的服
务小区包括授权频谱小区和非授权频谱小区,该服务小区均为已经激活的配有上行的小区,其中,S240生成第一功率余量信息,包括:
生成该第一功率余量信息,该第一功率余量信息包括该服务小区中各个小区的功率余量值,其中,该非授权频谱小区的功率余量值为虚拟值。
具体地,如图7所示,详见上文相关描述,这里不再赘述。
在本发明实施例中,对于授权频谱小区,在PHR MAC Control Element中上报的PH值是真实的,对于配有上行的激活LAA小区,在PHR MAC Control Element中上报的PH值是按虚拟值填充,能够一定程度上避免eNB分配的上行传输资源不当。
因此,在本发明实施例中,避免不通过LAA小区上报PHR,只有接收到授权频谱小区下发的UL grant之后,才会生成对应的PHR,通过该授权频谱小区上报PHR,能够有效提高上报PHR的及时性和可靠性。
应理解,本发明实施例提供的传输方法100和200同样适用于其他MAC Control Element的上报,如缓冲区状态报告(Buffer Status Report,简称为“BSR”)。缓冲区状态报告BSR过程告知eNB,UE共有多少数据存在上行的缓冲区里需要发送,为eNB提供上行调度的信息。BSR上报的数据包括RLC和PDCP缓冲区中的所有PDU和SDU。BSR过程需要RRC配置Periodic BSR-Timer和retx BSR-Timer两个定时器。
图10示出了本发明实施例提供的上行数据的传输方法300的示意性流程图,该传输方法300例如可以由用户设备UE执行,该方法300包括:
S310,该UE触发缓冲区状态报告BSR;
S320,接收第一服务小区的第一上行调度授权UL grant,所述第一服务小区为非授权频谱小区;
可选地,该第一UL grant可以由第一服务小区向该UE发送,也可以由另一个服务小区向该UE发送,例如该另一个服务小区为该UE的主小区,该第一服务小区为该UE的辅小区。
S330,根据该已经触发的BSR和该第一UL grant,生成第一缓冲区状态信息,并保留已经触发的BSR;
S340,根据该第一UL grant,向该第一服务小区发送该第一缓冲区状态信息。
在本发明实施例中,在未成功发送生成的BSR之前并不取消已经触发
的BSR(也可称之为悬挂已经触发的BSR),直到确定物理层成功发送生成的BSR之后,才取消已经触发的BSR,相对于现有技术,一定程度上能够保证BSR的及时传输,能够有效提高BSR的传输可靠性。
在S310中,具体地,BSR触发条件包括如下几种情况:
(1)常规BSR(Regular BSR):存在一个属于某一个逻辑信道组的逻辑信道,它对应的RLC或者PDCP实体里存在要发送的上行数据(例如RLC/PDCP的控制信息以及业务数据等);或者有一个逻辑信道,它的优先级高于任何属于某一逻辑信道组的信道,有数据需要发送。这些情况触发的BSR,称为“常规BSR”。
(2)周期性BSR(Periodic BSR):如果配置了periodicBSR-Timer,当periodicBSR-Timer超时,就会触发周期性BSR。
(3)填充BSR(Padding BSR):如果eNodeB分配的资源容纳传输数据之外仍有剩余,并且剩余的资源足够容纳对应BSR的MAC CE和相应的MAC头,将触发填充BSR。即填充BSR机制允许将剩余的上行资源用于BSR。
可选地,在本发明实施例中,S340根据该第一UL grant,向该第一服务小区发送该第一缓冲区状态信息,包括:
通过先听后说LBT过程竞争第一资源,当竞争该第一资源成功后,基于该第一资源向该第一服务小区发送该第一缓冲区状态信息,并取消已经触发的BSR,该第一资源为该第一UL grant指示的上行传输资源。
可选地,在本发明实施例中,该方法300还包括:
S350,当竞争该第一资源失败后,不向该第一服务小区发送该第一缓冲区状态信息,并继续保留已经触发的BSR。
可选地,在本发明实施例中,在竞争第一资源不成功的情况下,即不发送该第一缓冲区状态信息,并继续保留已经触发的BSR的情况下,该方法300还包括:
S360,接收第二服务小区的第二UL grant;
S370,根据该已经触发的BSR和该第二UL grant,生成第二缓冲区状态信息,并继续保留已经触发的BSR;
S380,根据该第二UL grant,向该第二服务小区发送该第二缓冲区状态信息,其中,该第二服务小区为非授权频谱小区或授权频谱小区。
可选地,在本发明实施例中,S370生成第二缓冲区状态信息,包括:
通过提高BSR的优先级,生成该第二缓冲区状态信息。
具体地,通过提高PHR在上文所述的生成MAC PDU的优先级顺序1)至5)中的优先级,生成包括该第二功率余量信息的MAC PDU。
对BSR的上述处理过程,与上文所述传输方法100中对PHR的描述类似,这里不再赘述。
图11示出了本发明另一实施例提供的上行数据的传输方法400的示意性流程图,该传输方法400例如由用户设备UE执行,该方法400包括:
S410,该UE触发缓冲区状态报告BSR;
S420,接收第一服务小区的第一上行调度授权UL grant;
可选地,该第一UL grant可以由第一服务小区向该UE发送,也可以由另一个服务小区向该UE发送,例如该另一个服务小区为该UE的主小区,该第一服务小区为该UE的辅小区。
S430,当该第一服务小区为非授权频谱小区时,保留已经触发的BSR;
S440,当该第一服务小区为授权频谱小区时,根据该已经触发的BSR和该第一UL grant,生成第一缓冲区状态信息,并基于该第一UL grant所向该第一服务小区发送该生成的第一缓冲区状态信息,并取消已经触发的BSR。
因此,在本发明实施例中,当接收到授权辅助接入小区的UL grant时,不向该非授权频谱小区发送BSR,只有当接收到授权频谱小区的UL grant时,才向该授权频谱小区发送BSR,能够避免通过非授权频谱小区发送BSR存在的传输可靠性差的问题。
可选地,在本发明实施例中,当该第一服务小区为非授权频谱小区时,不生成缓冲区状态信息。
可选地,在本发明实施例中,该第一服务小区为非授权频谱小区的情况下,即不向该第一服务小区发送BSR,并保留已经触发的BSR的情况下,该方法400还包括:
S450,接收第二服务小区的第二UL grant;
S460,当该第二服务小区为授权频谱小区时,根据该已经触发的BSR与该第二UL grant,生成第二缓冲区状态信息,根据该第二UL grant,向该第二服务小区发送该第二缓冲区状态信息,并取消已经触发的BSR。
可选地,在本发明实施例中,S450生成第二缓冲区状态信息,包括:
通过提高BSR的优先级,生成该第二缓冲区状态信息。
对BSR的上述处理过程,与上文所述传输方法200中对PHR的描述类似,这里不再赘述。
上文中结合图1至图11,详细描述了根据本发明实施例的上行数据的传输方法,下面将结合图12至图19,描述根据本发明实施例的用户设备。
图12示出了根据本发明实施例的用户设备500的示意性框图,该用户设备500包括:

因此,在本发明实施例中,避免不通过LAA小区上报PHR,只有接收到授权频谱小区下发的UL grant之后,才会生成对应的PHR,通过该授权频
