信息获取方法及通信装置Information acquisition method and communication device

本申请要求于2022年12月28日提交中国专利局、申请号为202211695507.4、申请名称为“信息获取方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims priority to the Chinese patent application filed with the China Patent Office on December 28, 2022, with application number 202211695507.4 and application name “Information Acquisition Method and Communication Device”, all contents of which are incorporated by reference in this application.

技术领域Technical Field

本申请涉及通信技术领域，尤其涉及一种信息获取方法及通信装置。The present application relates to the field of communication technology, and in particular to an information acquisition method and a communication device.

背景技术Background technique

通常终端设备在小区进行数据传输之前，需要获取定时提前(Timing advance，TA)信息，以实现终端设备与基站之间的上行同步。通常终端设备是通过随机接入过程实现TA信息的获取，例如，在小区切换场景中，终端设备接收到基站发送的切换命令时，切换到目标小区，终端设备在目标小区发起随机接入过程，并通过随机接入过程获取到TA信息，实现与基站的上行同步。显然这种在接收到切换命令后，再进行TA信息的获取会增加后续接入目标小区的时延开销。Usually, before a terminal device transmits data in a cell, it needs to obtain timing advance (TA) information to achieve uplink synchronization between the terminal device and the base station. Usually, the terminal device obtains TA information through a random access process. For example, in a cell switching scenario, when the terminal device receives a switching command sent by the base station, it switches to the target cell. The terminal device initiates a random access process in the target cell and obtains TA information through the random access process to achieve uplink synchronization with the base station. Obviously, the acquisition of TA information after receiving the switching command will increase the latency overhead of subsequent access to the target cell.

3、TA3. TA

在终端设备进行上行传输时，来自同一小区的不同用户设备(User Equipment，UE)的上行传输之间互不干扰。为了保证上行传输的正交性，避免小区内(intra-cell)干扰，基站要求来自同一子帧但不同频域资源的不同UE的信号到达基站的时间基本上是对齐的。基站只要在循环前缀(Cyclic Prefix，CP)范围内接收到UE所发送的上行数据，就能够正确地解码上行数据，因此，上行同步要求来自同一子帧的不同UE的信号到达基站的时间都落在CP之内。为了保证接收侧(基站侧)的时间同步，提出了定时提前(Timing Advance，TA)的机制。对于UE 侧，TA本质上是接收到下行子帧的起始时间与传输上行子帧的时间之间的一个负偏移(negative offset)。基站通过适当地控制每个UE的偏移，可以控制来自不同UE的上行信号到达基站的时间。对于离基站较远的UE，由于有较大的传输延迟，就要比离基站较近的UE提前发送上行数据。When the terminal device performs uplink transmission, the uplink transmissions from different user equipment (UE) in the same cell do not interfere with each other. In order to ensure the orthogonality of uplink transmission and avoid intra-cell interference, the base station requires that the time when the signals from different UEs in the same subframe but different frequency domain resources arrive at the base station is basically aligned. As long as the base station receives the uplink data sent by the UE within the cyclic prefix (CP) range, it can correctly decode the uplink data. Therefore, uplink synchronization requires that the time when the signals from different UEs in the same subframe arrive at the base station falls within the CP. In order to ensure time synchronization on the receiving side (base station side), a timing advance (TA) mechanism is proposed. For UE On the UE side, TA is essentially a negative offset between the start time of receiving the downlink subframe and the time of transmitting the uplink subframe. The base station can control the time when the uplink signal from different UEs arrives at the base station by properly controlling the offset of each UE. For UEs farther away from the base station, due to the larger transmission delay, uplink data must be sent earlier than UEs closer to the base station.

101，网络设备向终端设备发送m个候选小区分别对应的预配置信息，该预配置信息用于获取对应候选小区的TA信息，m为大于或者等于1的整数。相应的，终端设备接收m个候选小区分别对应的预配置信息。101, the network device sends pre-configuration information corresponding to m candidate cells to the terminal device. The pre-configuration information is used To obtain the TA information of the corresponding candidate cell, m is an integer greater than or equal to 1. Accordingly, the terminal device receives the pre-configuration information corresponding to the m candidate cells respectively.

其中，网络设备可以是终端设备所在源小区对应的网元，例如，该网元可以是图1a中的源网络设备(比如源基站)或者图1b中的S-DU。The network device may be a network element corresponding to a source cell where the terminal device is located. For example, the network element may be a source network device (such as a source base station) in FIG. 1a or an S-DU in FIG. 1b .

该m个候选小区可以是终端设备可能切换到的小区。在一些实施例中，该m个候选小区可以是网络设备根据终端设备上报的多个邻小区的参考信号的测量结果所确定的m个候选小区。例如，将该多个邻小区的参考信号按照测量值从大到小的顺序排序，将排序在最前的m个参考信号所对应的邻小区确定为m个候选小区。在一些实施例中，该m个候选小区也可以是网络设备所确定的p个候选小区中的部分候选小区，p为大于或者等于1的整数。该p个候选小区可以是网络设备根据终端设备上报的多个邻小区的参考信号的测量结果所确定的。换言之，网络设备配置p个候选小区中的部分候选小区用于提前获取TA信息的预配置信息。The m candidate cells may be cells to which the terminal device may switch. In some embodiments, the m candidate cells may be m candidate cells determined by the network device based on the measurement results of the reference signals of multiple neighboring cells reported by the terminal device. For example, the reference signals of the multiple neighboring cells are sorted in descending order according to the measured values, and the neighboring cells corresponding to the first m reference signals are determined as m candidate cells. In some embodiments, the m candidate cells may also be some of the p candidate cells determined by the network device, where p is an integer greater than or equal to 1. The p candidate cells may be determined by the network device based on the measurement results of the reference signals of multiple neighboring cells reported by the terminal device. In other words, the network device configures some of the p candidate cells for pre-configuration information for obtaining TA information in advance.

本申请实施例中候选小区对应的预配置信息可以用于获取该候选小区的TA信息。示例性的，该预配置信息中可以包括对应候选小区的资源信息，该资源即是所配置的用于获取该候选小区的TA信息的资源。In the embodiment of the present application, the pre-configuration information corresponding to the candidate cell can be used to obtain the TA information of the candidate cell. Exemplarily, the pre-configuration information may include resource information corresponding to the candidate cell, and the resource is the resource configured for obtaining the TA information of the candidate cell.

示例性的，m个候选小区分别对应的预配置信息可以是通过候选小区配置信息发送给终端设备的。该候选小区配置信息用于配置终端设备待切换的候选小区。示例性的，该m个候选小区可以为网络设备所确定的p个候选小区中的部分候选小区，则该候选小区配置信息中可以包括p个候选小区的配置信息，进而该p个候选小区的配置信息中包括该m个候选小区分别对应的配置信息。Exemplarily, the pre-configuration information corresponding to the m candidate cells can be sent to the terminal device through the candidate cell configuration information. The candidate cell configuration information is used to configure the candidate cell to be switched by the terminal device. Exemplarily, the m candidate cells can be part of the p candidate cells determined by the network device, then the candidate cell configuration information can include the configuration information of the p candidate cells, and then the configuration information of the p candidate cells includes the configuration information corresponding to the m candidate cells.

102，终端设备根据m个候选小区分别对应的预配置信息，获取n个候选小区分别对应的TA信息，n为小于或者等于m的整数。102. The terminal device obtains TA information corresponding to n candidate cells respectively according to pre-configuration information corresponding to m candidate cells respectively, where n is an integer less than or equal to m.

在一些实施例中，该m可以等于n，即网络设备发送m个候选小区的预配置信息，终端设备即根据该m个候选小区的预配置信息获取到该m个候选小区的TA信息。该TA信息用于实现终端设备在对应候选小区的上行同步。In some embodiments, m may be equal to n, that is, the network device sends pre-configuration information of m candidate cells, and the terminal device obtains TA information of the m candidate cells according to the pre-configuration information of the m candidate cells. The TA information is used to achieve uplink synchronization of the terminal device in the corresponding candidate cell.

在一些实施例中，该m可以大于n，即网络设备发送m个候选小区的预配置信息，终端设备仅获取m个候选小区中的部分候选小区的TA信息。示例性的，网络设备可发送指示信息，该指示信息用于指示获取该m个候选小区中n个候选小区的TA信息。可选的，该指示信息还可以用于指示该n个候选小区的标识。其中，该指示信息可以携带于媒体接入控制元素(medium access control control element，MAC CE)或下行控制信息(Downlink Control Information，DCI)中。 In some embodiments, m may be greater than n, that is, the network device sends pre-configuration information of m candidate cells, and the terminal device only obtains TA information of some of the m candidate cells. Exemplarily, the network device may send indication information, and the indication information is used to indicate the acquisition of TA information of n candidate cells among the m candidate cells. Optionally, the indication information can also be used to indicate the identifiers of the n candidate cells. The indication information can be carried in a medium access control element (MAC CE) or downlink control information (DCI).

其中，上述候选小区对应的预配置信息中包括该候选小区的资源信息，该资源即是用于获取该候选小区的TA信息。换言之，候选小区对应的预配置信息中配置了用于获取该候选小区的TA信息的资源。终端设备即可在预配置信息中所配置的资源上向对应候选小区请求TA信息，并接收候选小区返回的TA信息。Among them, the pre-configuration information corresponding to the candidate cell includes the resource information of the candidate cell, and the resource is used to obtain the TA information of the candidate cell. In other words, the pre-configuration information corresponding to the candidate cell is configured with resources for obtaining the TA information of the candidate cell. The terminal device can request TA information from the corresponding candidate cell on the resources configured in the pre-configuration information, and receive the TA information returned by the candidate cell.

例如，终端设备在候选小区的预配置信息中所配置的资源上发起随机接入过程以获取该候选小区的TA信息。具体可选的，终端设备在候选小区的预配置信息中所配置的资源上向网络设备发送前导码后，网络设备确定TA，然后将TA信息通过随机接入响应消息发送给终端设备。For example, the terminal device initiates a random access process on the resources configured in the pre-configuration information of the candidate cell to obtain the TA information of the candidate cell. Specifically, after the terminal device sends a preamble code to the network device on the resources configured in the pre-configuration information of the candidate cell, the network device determines the TA and then sends the TA information to the terminal device via a random access response message.

在一些实施例中，上述m个候选小区的数量或者上述n个候选小区的数量可以是终端设备支持提前获取TA信息的候选小区的数量。In some embodiments, the number of the m candidate cells or the number of the n candidate cells may be the number of candidate cells that the terminal device supports for obtaining TA information in advance.

情况1，如果上述m个候选小区的数量是终端设备支持提前获取TA信息的候选小区的数量。具体可选的，终端设备向网络设备发送能力信息，该能力信息用于指示终端设备支持提前获取TA信息的候选小区的数量，即终端设备进行能力上报。网络设备根据终端设备上报的能力信息确定需配置预配置信息的候选小区数量，并发送m个候选小区分别对应的预配置信息。其中，上述能力信息可以是与各个邻小区的测量结果一同上报给网络设备，即携带于测量上报消息中；或者也可以使用专用的能力上报信令发送该能力信息。Case 1, if the number of the above m candidate cells is the number of candidate cells that the terminal device supports for obtaining TA information in advance. Specifically and optionally, the terminal device sends capability information to the network device, and the capability information is used to indicate the number of candidate cells that the terminal device supports for obtaining TA information in advance, that is, the terminal device reports the capability. The network device determines the number of candidate cells that need to be configured with pre-configuration information based on the capability information reported by the terminal device, and sends the pre-configuration information corresponding to the m candidate cells respectively. Among them, the above capability information can be reported to the network device together with the measurement results of each neighboring cell, that is, carried in the measurement report message; or the capability information can be sent using dedicated capability reporting signaling.

情况2，如果上述n个候选小区的数量是终端设备支持提前获取TA信息的候选小区的数量。具体可选的，终端设备向网络设备发送能力信息，该能力信息用于指示终端设备支持提前获取TA信息的候选小区的数量，即终端设备进行能力上报。网络设备根据终端设备上报的能力信息确定m个候选小区中需要进行提前TA信息获取的候选小区数量n，并向终端设备发送上述指示信息，关于指示信息的描述具体可参照上述实施例的描述，在此不再赘述。Case 2, if the number of the above n candidate cells is the number of candidate cells that the terminal device supports for obtaining TA information in advance. Specifically and optionally, the terminal device sends capability information to the network device, and the capability information is used to indicate the number of candidate cells that the terminal device supports for obtaining TA information in advance, that is, the terminal device reports the capability. The network device determines the number n of candidate cells that need to obtain TA information in advance among the m candidate cells based on the capability information reported by the terminal device, and sends the above indication information to the terminal device. For the description of the indication information, please refer to the description of the above embodiment, which will not be repeated here.

可理解，在上述情况1和情况2中，终端设备发送的能力信息也可以是用于指示终端设备支持提前获取TA信息，网络设备根据终端设备的能力信息发送m个候选小区的预配置信息或者指示信息。It can be understood that in the above cases 1 and 2, the capability information sent by the terminal device can also be used to indicate that the terminal device supports obtaining TA information in advance, and the network device sends pre-configuration information or indication information of m candidate cells according to the capability information of the terminal device.

本申请实施例中，可提前获取到n个候选小区分别对应的TA信息，从而在后续需要接入该n个候选小区中的目标小区时，不需要再去获取TA信息，从而减少接入小区的时延开销。In the embodiment of the present application, TA information corresponding to each of n candidate cells can be acquired in advance, so that when a target cell among the n candidate cells needs to be accessed later, there is no need to acquire the TA information, thereby reducing the delay overhead of accessing the cell.

如图2b所示，是本申请实施例提供的另一种信息获取方法的流程示意图，如图2b所示，该方法可以包括但不限于以下步骤：As shown in FIG2b, it is a flow chart of another information acquisition method provided in an embodiment of the present application. As shown in FIG2b, The method may include but is not limited to the following steps:

201，第一网络设备确定q个候选小区，q为大于0的整数。201. A first network device determines q candidate cells, where q is an integer greater than 0.

其中，第一网络设备可以是终端设备所在源小区对应的网元，例如，该网元可以是图1a中的源网络设备(比如源基站)或者图1b中的S-DU。Among them, the first network device can be a network element corresponding to the source cell where the terminal device is located. For example, the network element can be the source network device in Figure 1a (such as a source base station) or the S-DU in Figure 1b.

该q个候选小区可以是第一网络设备根据终端设备上报的多个邻小区的参考信号的测量结果所确定的q个候选小区，即q与图2a实施例中的p相同。该q个候选小区也可以是第一网络设备确定的可提前获取TA信息的候选小区，即q个候选小区是第一网络设备确定的所有候选小区中的部分小区，该种场景中，q小于p。例如，从p个候选小区中确定信号质量最优的q个候选小区，即终端设备最可能切换到该q个候选小区。The q candidate cells may be q candidate cells determined by the first network device according to the measurement results of the reference signals of multiple neighboring cells reported by the terminal device, that is, q is the same as p in the embodiment of Figure 2a. The q candidate cells may also be candidate cells whose TA information can be obtained in advance determined by the first network device, that is, the q candidate cells are part of all the candidate cells determined by the first network device, and in this scenario, q is less than p. For example, q candidate cells with the best signal quality are determined from the p candidate cells, that is, the terminal device is most likely to switch to the q candidate cells.

在一些实现方式中，上述测量结果可以是基于层3测量的测量结果，该层3可以是无线资源控制层(Radio Resource Control，RRC)。In some implementations, the measurement results may be measurement results based on layer 3 measurements, where layer 3 may be a radio resource control layer (Radio Resource Control, RRC).

202，第一网络设备向第二网络设备发送请求消息，该请求消息用于请求获取候选小区的预配置信息，该预配置信息用于获取该候选小区的TA信息。202. The first network device sends a request message to the second network device. The request message is used to request to obtain pre-configuration information of a candidate cell. The pre-configuration information is used to obtain TA information of the candidate cell.

203，第二网络设备向第一网络设备发送候选小区的预配置信息。203. The second network device sends pre-configuration information of the candidate cell to the first network device.

其中，第二网络设备可以是候选小区对应的网元，例如，该网元可以是图1a中的目标网络设备(比如目标基站)或者图1b中的T-DU。The second network device may be a network element corresponding to the candidate cell, for example, the network element may be the target network device (such as a target base station) in FIG. 1a or the T-DU in FIG. 1b .

第一网络设备确定q个候选小区分别对应的网元，即确定q个候选小区分别对应的第二网络设备，可理解，该q个候选小区可以对应同一个第二网络设备，也可以对应多个第二网络设备，本申请不作限定。例如，该q个候选小区包括候选小区1、候选小区2和候选小区3，候选小区1和候选小区2对应一个第二网络设备，候选小区3对应另一个第二网络设备。The first network device determines the network elements corresponding to the q candidate cells, that is, determines the second network devices corresponding to the q candidate cells. It can be understood that the q candidate cells can correspond to the same second network device or multiple second network devices, which is not limited in this application. For example, the q candidate cells include candidate cell 1, candidate cell 2, and candidate cell 3. Candidate cell 1 and candidate cell 2 correspond to one second network device, and candidate cell 3 corresponds to another second network device.

第一网络设备向第二网络设备发送请求消息，以请求获取该第二网络设备所对应候选小区的预配置信息。可理解，如果q个候选小区对应多个第二网络设备，则终端设备需分别向各个第二网络设备发送请求消息。继续以上述q个候选小区包括候选小区1、候选小区2和候选小区3，候选小区1和候选小区2对应一个第二网络设备(为方便描述，记为网络设备a)，候选小区3对应另一个第二网络设备(为方便描述，记为网络设备b)作为举例，第一网络设备向网络设备a发送请求消息，以请求候选小区1和候选小区2的预配置信息，即请求网络设备a分配用于获取候选小区1和候选小区2的TA信息的资源。第一网络设备向网络设备b发送请求消息，以请求候选小区3的预配置信息，即请求网络设备b分配用于获取候选小区3的TA信息的资源。The first network device sends a request message to the second network device to request the pre-configuration information of the candidate cell corresponding to the second network device. It can be understood that if the q candidate cells correspond to multiple second network devices, the terminal device needs to send a request message to each second network device respectively. Continuing with the above q candidate cells including candidate cell 1, candidate cell 2 and candidate cell 3, candidate cell 1 and candidate cell 2 correspond to a second network device (for the convenience of description, denoted as network device a), and candidate cell 3 corresponds to another second network device (for the convenience of description, denoted as network device b) as an example, the first network device sends a request message to network device a to request the pre-configuration information of candidate cell 1 and candidate cell 2, that is, request network device a to allocate resources for obtaining the TA information of candidate cell 1 and candidate cell 2. The first network device sends a request message to network device b to request the pre-configuration information of candidate cell 3, that is, request network device b to allocate resources for obtaining the TA information of candidate cell 3.

相应的，第二网络设备向第一网络设备发送所请求的候选小区的预配置信息。 Correspondingly, the second network device sends the requested pre-configuration information of the candidate cell to the first network device.

在一些实施例中，第一网络设备第二网络设备请求获取预配置信息的候选小区的数量可以是大于或者等于第二网络设备实际返回预配置信息的候选小区数量，例如，第一网络设备向第二网络设备请求候选小区1和候选小区2的预配置信息，但是第二网络设备可能实际仅返回候选小区1的预配置信息。为便于描述，本申请第一网络设备请求q个候选小区的预配置信息，接收到r个候选小区的预配置信息，该q大于或者等于r，r为大于0的整数。In some embodiments, the number of candidate cells for which the first network device and the second network device request to obtain preconfiguration information may be greater than or equal to the number of candidate cells for which the second network device actually returns preconfiguration information. For example, the first network device requests the preconfiguration information of candidate cell 1 and candidate cell 2 from the second network device, but the second network device may actually only return preconfiguration information of candidate cell 1. For ease of description, in the present application, the first network device requests preconfiguration information of q candidate cells and receives preconfiguration information of r candidate cells, where q is greater than or equal to r, and r is an integer greater than 0.

204，第一网络设备向终端设备发送m个候选小区分别对应的预配置信息，m为大于或者等于1的整数。204. The first network device sends pre-configuration information corresponding to m candidate cells to the terminal device, where m is an integer greater than or equal to 1.

在一些实施例中，第一网络设备从第二网络设备接收的是r个候选小区分别对应的预配置信息，第一网络设备向终端设备发送的m个候选小区分别对应的预配置信息，该m可以小于或者等于r。如果m等于r，则说明第一网络设备将所接收的r个候选小区分别对应的预配置信息全部发送给终端设备。如果m小于r，则说明第一网络设备将所接收的r个候选小区分别对应的预配置信息中的部分候选小区的预配置信息发送给终端设备。In some embodiments, the first network device receives pre-configuration information corresponding to r candidate cells from the second network device, and the first network device sends pre-configuration information corresponding to m candidate cells to the terminal device, where m may be less than or equal to r. If m is equal to r, it means that the first network device sends all the received pre-configuration information corresponding to the r candidate cells to the terminal device. If m is less than r, it means that the first network device sends the pre-configuration information of some candidate cells among the received pre-configuration information corresponding to the r candidate cells to the terminal device.

205，终端设备根据m个候选小区分别对应的预配置信息，获取n个候选小区分别对应的TA信息，m个候选小区包括该n个候选小区，n为小于或者等于m的整数。205. The terminal device obtains TA information corresponding to n candidate cells respectively according to pre-configuration information corresponding to m candidate cells respectively, where the m candidate cells include the n candidate cells, and n is an integer less than or equal to m.

本申请实施例步骤204-步骤205请参照图2a的步骤101-步骤102，在此不再赘述。Please refer to step 101 - step 102 of FIG. 2a for step 204 - step 205 of the embodiment of the present application, and will not be described in detail here.

本申请实施例中，第一网络设备在确定m个候选小区之后，即向各个候选小区对应的第二网络设备请求分配用于提前获取TA信息的资源，从而便于终端设备可在切换之前完成各个候选小区的TA信息获取，实现上行同步，减少后续切换时需获取目标小区TA信息所带来的时延。In an embodiment of the present application, after determining m candidate cells, the first network device requests the second network device corresponding to each candidate cell to allocate resources for obtaining TA information in advance, so that the terminal device can complete the TA information acquisition of each candidate cell before switching, achieve uplink synchronization, and reduce the delay caused by the need to obtain the TA information of the target cell during subsequent switching.

Further, for each neighboring cell, at least one measurement value of the neighboring cell is filtered through layer 3, for example, the at least one measurement value is weighted and summed to obtain the layer 3 filtering result of the neighboring cell.

For example, the layer 3 filtering results of the q candidate cells are the optimal preset number of candidate cells in the at least one neighboring cell. The preset number can be configured by the network device.

303，源网络设备向目标网络设备发送请求消息，该请求消息用于请求获取候选小区的预配置信息，该预配置信息用于获取该候选小区的TA信息。303. The source network device sends a request message to the target network device. The request message is used to request to obtain pre-configuration information of the candidate cell. The pre-configuration information is used to obtain TA information of the candidate cell.

具体可选的，源网络设备可确定q个候选小区分别对应的目标网络设备，q个候选小区可对应同一个目标网络设备，也可对应多个目标网络设备。如果q个候选小区对应多个目标网络设备，则可分别向各个目标网络设备发送请求消息，以请求获取该目标网络设备对应候选小区的预配置信息。Specifically, the source network device may determine the target network devices corresponding to the q candidate cells respectively, and the q candidate cells may correspond to the same target network device or to multiple target network devices. If the q candidate cells correspond to multiple target network devices, a request message may be sent to each target network device respectively to request to obtain the pre-configuration information of the candidate cell corresponding to the target network device.

304，目标网络设备向源网络设备发送候选小区的预配置信息。304. The target network device sends pre-configuration information of the candidate cell to the source network device.

Specifically, the terminal device may measure the synchronization signal corresponding to the beam of each candidate cell to obtain the measurement result.

308，源网络设备向终端设备发送小区切换命令。308. The source network device sends a cell switching command to the terminal device.

源网络设备根据终端设备上报的各个候选小区的测量结果，确定终端设备需要切换到的目标小区，并发送小区切换命令，该切换命令用于指示终端设备切换到目标小区。The source network device determines the target cell to which the terminal device needs to switch based on the measurement results of each candidate cell reported by the terminal device, and sends a cell switching command, which is used to instruct the terminal device to switch to the target cell.

309，终端设备与目标小区进行通信。309, the terminal device communicates with the target cell.

当源网络设备指示终端设备切换到目标小区时，由于终端设备提前获取了目标小区的TA信息，因此终端设备可不用重复获取TA信息，极大提高接入目标小区的效率。When the source network device instructs the terminal device to switch to the target cell, since the terminal device has obtained the TA information of the target cell in advance, the terminal device does not need to repeatedly obtain the TA information, which greatly improves the efficiency of accessing the target cell.
