Description
技术领域technical field
本发明涉及无线通信技术领域，尤其涉及一种进行SSTD测量的方法、装置及用户设备。The present invention relates to the field of wireless communication technologies, and in particular, to a method, apparatus and user equipment for performing SSTD measurement.
背景技术Background technique
随着无线通信技术的发展，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)引入了NR(New Radio，新空口)技术。在3GPP R15中，为了配置EN-DC(EUTRAN-NR Dual Connectivity，EUTRAN-NR双连接)，LTE(Long Term Evolution，长期演进)基站需要知道NR小区的定时(timing)信息。在有些网络部署场景，LTE基站可以配置UE对NR小区进行SSTD(SFN andSubframe Timing Difference，系统帧号和子帧定时偏差)测量，UE将待测量的NR小区与当前PCell(LTE小区)之间的时间差值上报给MeNB。另外，为了配置NR-NR DC(NR-NR Dual Connectivity，NR-NR双连接)，NR基站可以配置UE对NR小区进行SSTD测量。With the development of wireless communication technology, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced NR (New Radio, new air interface) technology. In 3GPP R15, in order to configure EN-DC (EUTRAN-NR Dual Connectivity, EUTRAN-NR dual connectivity), the LTE (Long Term Evolution, Long Term Evolution) base station needs to know the timing information of the NR cell. In some network deployment scenarios, the LTE base station can configure the UE to measure the SSTD (SFN and Subframe Timing Difference, system frame number and subframe timing difference) on the NR cell. The UE measures the time between the NR cell to be measured and the current PCell (LTE cell). The difference is reported to the MeNB. In addition, in order to configure NR-NR DC (NR-NR Dual Connectivity, NR-NR dual connectivity), the NR base station may configure the UE to perform SSTD measurement on the NR cell.
现有技术中，主基站(可以是LTE基站，也可以是NR基站)在配置SSTD测量(指对NR小区的SSTD测量，下同)时，基站可能为UE配置了测量间隙，也可能没有配置测量间隙。即使配置了测量间隙，由于主基站还不知道目标小区的定时，所以已配置的测量间隙可能并不合适于对目标小区的SSTD测量。也就是说，在这些情况下UE可能无法成功获取目标小区与PCell的时间差，导致UE可能无法获取NR小区的SSTD信息。In the prior art, when the primary base station (which may be an LTE base station or an NR base station) configures SSTD measurement (referring to SSTD measurement on an NR cell, the same below), the base station may or may not configure a measurement gap for the UE. Measure the gap. Even if the measurement gap is configured, since the primary base station does not yet know the timing of the target cell, the configured measurement gap may not be suitable for SSTD measurement on the target cell. That is to say, in these cases, the UE may fail to obtain the time difference between the target cell and the PCell, so that the UE may fail to obtain the SSTD information of the NR cell.

本发明实施例提供的进行SSTD测量的方法，当UE进行对NR小区的SSTD测量需要测量间隙时，根据当前配置测量间隙的情况，选择利用当前所配置的测量间隙进行SSTD测量、在非连续接收的睡眠时间进行SSTD测量、利用自发的测量间隙进行SSTD测量或者利用向基站请求后获得的测量间隙进行SSTD测量，从而能够保证UE获取NR小区的SSTD信息。In the method for performing SSTD measurement provided by the embodiment of the present invention, when a measurement gap is required for the UE to perform SSTD measurement on an NR cell, according to the situation of the currently configured measurement gap, it is selected to use the currently configured measurement gap to perform SSTD measurement, and to use the currently configured measurement gap to perform SSTD measurement during discontinuous reception. The SSTD measurement is performed during the sleep time of the NR cell, the SSTD measurement is performed using the spontaneous measurement gap, or the SSTD measurement is performed using the measurement gap obtained after requesting the base station, so as to ensure that the UE obtains the SSTD information of the NR cell.
下面对本发明进行SSTD测量的方法进行详细说明。The method for performing SSTD measurement in the present invention will be described in detail below.
当UE进行对NR小区的SSTD测量时，在某些情况下需要测量间隙，包括但不限于：When the UE performs SSTD measurement on an NR cell, a measurement gap is required in some cases, including but not limited to:
服务小区为LTE小区；The serving cell is an LTE cell;
目标小区与NR服务小区异频；The target cell and the NR serving cell are inter-frequency;
目标小区与NR服务小区同频，但是numerology(参数配置)不同。The target cell is on the same frequency as the NR serving cell, but the numerology (parameter configuration) is different.
当UE进行对NR小区的SSTD测量时，如果需要测量间隙，但是当前没有配置测量间隙，可以采用如下的方式：When the UE performs SSTD measurement on an NR cell, if a measurement gap is required, but no measurement gap is currently configured, the following methods can be used:
(1)如果基站为UE配置了DRX(Discontinuous Reception，非连续接收)，UE在非连续接收的睡眠时间进行SSTD测量。(1) If the base station configures DRX (Discontinuous Reception, discontinuous reception) for the UE, the UE performs SSTD measurement during the sleep time of the discontinuous reception.
(2)UE利用自发的测量间隙进行SSTD测量。(2) The UE uses the spontaneous measurement gap to perform SSTD measurement.
另外，为了实现基站对UE进行控制，基站可以通过RRC(Radio ResourceControl，无线资源控制)信令配置一个参数，指示UE是否可以使用自发测量间隙进行SSTD测量，当UE接收到基站配置的参数指示UE可以使用自发测量间隙进行SSTD测量时，UE利用自发的测量间隙进行SSTD测量。In addition, in order to enable the base station to control the UE, the base station can configure a parameter through RRC (Radio Resource Control, Radio Resource Control) signaling to indicate whether the UE can use the spontaneous measurement gap to perform SSTD measurement. When the UE receives the parameter configured by the base station, it indicates to the UE When the SSTD measurement can be performed using the spontaneous measurement gap, the UE uses the spontaneous measurement gap to perform the SSTD measurement.
(3)如果UE在非连续接收的睡眠时间进行SSTD测量或者UE利用自发的测量间隙进行SSTD测量还是无法获取目标小区的SSB(如接收不到信号)，或者基站没有为UE配置非连续接收，此时无法获取目标小区的同步信号块，UE通过RRC信令向基站请求测量间隙，UE还可以提供建议的一个或多个测量间隙周期和/或测量间隙偏移值，以便基站配置合适的测量间隙。基站收到UE的信请求后，可以给UE配置合适的测量间隙，UE接收到基站配置的合适的测量间隙后，利用该测量间隙进行SSTD测量。(3) If the UE performs SSTD measurement during the sleep time of discontinuous reception or the UE performs SSTD measurement using a spontaneous measurement gap, the SSB of the target cell cannot be obtained (for example, no signal is received), or the base station does not configure discontinuous reception for the UE, At this time, the synchronization signal block of the target cell cannot be obtained. The UE requests a measurement gap from the base station through RRC signaling. The UE can also provide one or more recommended measurement gap periods and/or measurement gap offset values, so that the base station can configure appropriate measurement gaps. gap. After receiving the letter request from the UE, the base station can configure an appropriate measurement gap for the UE. After receiving the appropriate measurement gap configured by the base station, the UE uses the measurement gap to perform SSTD measurement.
当UE进行对NR小区的SSTD测量时，如果需要测量间隙，并且当前已经配置测量间隙，可以采用如下的方式：When the UE performs SSTD measurement on an NR cell, if a measurement gap is required and the measurement gap is currently configured, the following methods can be used:
(1)UE利用当前所配置的测量间隙进行SSTD测量。(1) The UE uses the currently configured measurement gap to perform SSTD measurement.
(2)如果UE利用当前所配置的测量间隙进行SSTD测量无法获取目标小区的SSB(同步信号块)，且基站为UE配置了非连续接收，则UE在非连续接收的睡眠时间进行SSTD测量；或者，UE还可以利用自发的测量间隙进行测量。(2) If the UE uses the currently configured measurement gap to perform SSTD measurement and cannot obtain the SSB (synchronization signal block) of the target cell, and the base station configures discontinuous reception for the UE, the UE performs SSTD measurement during the sleep time of discontinuous reception; Alternatively, the UE may also perform measurement by using a spontaneous measurement gap.
其中，UE利用自发的测量间隙进行测量的具体实现过程可以参照上述没有配置测量间隙时的方式(2)，在此不再赘述。The specific implementation process of the UE using the spontaneous measurement gap to perform measurement may refer to the above-mentioned mode (2) when the measurement gap is not configured, and details are not repeated here.
(3)如果UE在非连续接收的睡眠时间进行SSTD测量或者利用自发的测量间隙进行SSTD测量仍无法获取目标小区的同步信号块，有可能是测量的时间窗口不合适，则UE向基站请求新的测量间隙，具体实现过程可以参照上述没有配置测量间隙时的方式(3)，在此不再赘述。(3) If the UE performs SSTD measurement during the sleep time of discontinuous reception or uses the spontaneous measurement gap to perform SSTD measurement and still cannot obtain the synchronization signal block of the target cell, it may be that the measurement time window is not suitable, and the UE requests the base station for a new For the specific implementation process, refer to the above-mentioned method (3) when no measurement gap is configured, and details are not repeated here.
