Description

Processing method, communication device and storage medium

Technical Field

本申请涉及通信技术领域，尤其涉及一种处理方法、通信设备及存储介质。The present application relates to the field of communication technology, and in particular to a processing method, a communication device and a storage medium.

Background Art

现有协议中，PRACH(Physical Random Access CHannel，物理随机接入信道)是通信系统中的一个上行链路物理信道，主要用于终端设备向网络设备发送随机接入请求，以建立无线连接或保证上行同步。In the existing protocol, PRACH (Physical Random Access Channel) is an uplink physical channel in the communication system, which is mainly used for terminal devices to send random access requests to network devices to establish wireless connections or ensure uplink synchronization.

在构思及实现本申请过程中，发明人发现至少存在如下问题：由于PRACH传输是一个周期性传输信道，当没有终端设备业务时，由于网络设备不知道是否有终端设备进行随机接入，因此，需要周期性地在规定的随机接入时机进行前导码检测，从而会带来不必要的信令交互，和/或增加网络能耗。In the process of conceiving and implementing the present application, the inventors discovered that there are at least the following problems: Since PRACH transmission is a periodic transmission channel, when there is no terminal device service, the network device does not know whether there is a terminal device performing random access. Therefore, it is necessary to periodically perform preamble code detection at the specified random access time, which will cause unnecessary signaling interaction and/or increase network energy consumption.

前面的叙述在于提供一般的背景信息，并不一定构成现有技术。The preceding description is intended to provide general background information and does not necessarily constitute prior art.

When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素，和/或，本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义，也可能具有不同含义，其具体含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。It should be noted that, in this article, the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element, and/or, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

应当理解，尽管在本文可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本文范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语"如果"可以被解释成为"在……时"或"当……时"或"响应于确定"。再者，如同在本文中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组，但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。本申请使用的术语“或”、“和/或”、“包括以下至少一个”等可被解释为包括性的，或意味着任一个或任何组合。例如，“包括以下至少一个：A、B、C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A和B和C”，再如，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A和B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。It should be understood that, although the terms first, second, third, etc. may be used to describe various information in this article, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determination". Furthermore, as used in this article, the singular forms "one", "one" and "the" are intended to also include plural forms, unless there is an opposite indication in the context. It should be further understood that the terms "comprising" and "including" indicate that there are the described features, steps, operations, elements, components, projects, kinds, and/or groups, but do not exclude the existence, occurrence or addition of one or more other features, steps, operations, elements, components, projects, kinds, and/or groups. The terms "or", "and/or", "including at least one of the following" etc. used in this application can be interpreted as inclusive, or mean any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”, and for another example, “A, B or C” or “A, B and/or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will only occur when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

应该理解的是，虽然本申请实施例中的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。而且，图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。It should be understood that, although the various steps in the flowchart in the embodiment of the present application are displayed in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and it can be performed in other orders. Moreover, at least a portion of the steps in the figure may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

取决于语境，如在此所使用的词语“如果”、“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

需要说明的是，在本文中，采用了诸如S1、S2等步骤代号，其目的是为了更清楚简要地表述相应内容，不构成顺序上的实质性限制，本领域技术人员在具体实施时，可能会先执行S2后执行S1等，但这些均应在本申请的保护范围之内。It should be noted that in this article, step codes such as S1 and S2 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the order.

第四实施例Fourth embodiment

在本申请上述任一实施例的基础上，本实施例进一步公开了基于无线资源控制信息确定第一随机接入配置，根据下行链路控制信息中的随机接入请求字段，使能或去使能第一随机接入配置中随机接入配置周期或随机接入关联周期内的所有随机接入时机的方法。Based on any of the above embodiments of the present application, this embodiment further discloses a method for determining a first random access configuration based on wireless resource control information, and enabling or disabling all random access opportunities within a random access configuration period or a random access association period in the first random access configuration according to a random access request field in the downlink control information.

可选地，基于无线资源控制信息确定第一随机接入配置包括：基于线资源控制信息中的随机接入配置索引(prach-ConfigurationIndex)字段及协议38.211中的Table 6.3.3.2-2、Table 6.3.3.2-3以及Table 6.3.3.2-4，获取随机接入时机的时域和频域位置。Optionally, determining the first random access configuration based on the wireless resource control information includes: obtaining the time domain and frequency domain positions of the random access timing based on the random access configuration index (prach-ConfigurationIndex) field in the wireless resource control information and Table 6.3.3.2-2, Table 6.3.3.2-3 and Table 6.3.3.2-4 in protocol 38.211.

可选地，随机接入配置周期由无线资源控制信息中的随机接入配置索引(prach-ConfigurationIndex)字段确定。Optionally, the random access configuration period is determined by a random access configuration index (prach-ConfigurationIndex) field in the radio resource control information.

可选地，对于FR1和FDD，采用协议38.211中的Table 6.3.3.2-2确定随机接入配置周期。设无线资源控制信息中的prach-ConfigurationIndex取值为9，则根据协议可知终端设备在n_SFN mod4＝1的系统帧(x＝4,y＝0。即n_SFN mod4＝1,5,9,...的系统帧)的子帧4上传输格式0的前导码。因此，根据无线资源控制信息中的随机接入配置索引字段确定的随机接入配置周期为40ms。Optionally, for FR1 and FDD, Table 6.3.3.2-2 in protocol 38.211 is used to determine the random access configuration period. Assuming that the prach-ConfigurationIndex in the radio resource control information is 9, it can be known from the protocol that the terminal device transmits the preamble of format 0 in subframe 4 of the system frame of n _SFN mod4＝1 (x＝4, y＝0. That is, the system frame of n _SFN mod4＝1,5,9,...). Therefore, the random access configuration period determined by the random access configuration index field in the radio resource control information is 40ms.

可选地，根据下行链路控制信息中的随机接入请求字段，使能或去使能第一随机接入配置中随机接入配置周期内的所有随机接入时机。可选地，下行链路控制信息位于由下行链路控制信息指示使能的随机接入配置周期内。比如，设第一随机接入配置确定的一个随机接入配置周期内的随机接入时机共有32个。设该随机接入配置周期内包含的下行链路控制信息中的随机接入请求字段取值为1，则该随机接入配置周期内的32个随机接入时机均被使能。Optionally, according to the random access request field in the downlink control information, all random access opportunities in the random access configuration period in the first random access configuration are enabled or disabled. Optionally, the downlink control information is located in the random access configuration period indicated to be enabled by the downlink control information. For example, suppose there are 32 random access opportunities in a random access configuration period determined by the first random access configuration. Suppose the value of the random access request field in the downlink control information contained in the random access configuration period is 1, then all 32 random access opportunities in the random access configuration period are enabled.

可选地，根据下行链路控制信息中的随机接入请求字段，使能或去使能第一随机接入配置中随机接入关联周期内的所有随机接入时机。可选地，下行链路控制信息位于由下行链路控制信息指示使能的随机接入关联周期对应的第一个随机接入配置周期中。比如，设第一随机接入配置确定的一个随机接入关联周期内的随机接入时机共有32个。设随机接入关联周期对应的下行链路控制信息中随机接入请求字段取值为1，则该随机接入关联周期内的32个随机接入时机被使能。Optionally, according to the random access request field in the downlink control information, all random access opportunities in the random access association period in the first random access configuration are enabled or disabled. Optionally, the downlink control information is located in the first random access configuration period corresponding to the random access association period enabled by the downlink control information. For example, suppose there are 32 random access opportunities in a random access association period determined by the first random access configuration. Suppose the value of the random access request field in the downlink control information corresponding to the random access association period is 1, then 32 random access opportunities in the random access association period are enabled.

可选地，一个随机接入时机可以关联一个或多个SSB。Optionally, a random access opportunity may be associated with one or more SSBs.

可选地，随机接入关联周期为完成一次N_Tx ^SSB个SSB映射到一个随机接入时机一次，所需的随机接入配置周期个数的最小值，且随机接入关联周期的取值满足表1：Optionally, the random access association period is the minimum number of random access configuration periods required to complete mapping of N _Tx ^SSB SSBs to one random access opportunity once, and the value of the random access association period satisfies Table 1:

表1、随机接入配置周期和同步信号块到随机接入时机映射的关联周期之间的映射示例表
Table 1. Example of mapping between random access configuration period and associated period of synchronization signal block to random access opportunity mapping

可选地，N_Tx ^SSB由无线资源控制信息中的同步信号块突发位置(ssb-PositionsInBurst)字段确定。Optionally, N _Tx ^SSB is determined by a synchronization signal block burst position (ssb-PositionsInBurst) field in the radio resource control information.

参照图8，图8为根据第四实施例示出的第一示例示意图，设无线资源控制信息中的ssb-PositionsInBurst字段取值为“11111111”，因此，5ms内真实传输的同步信号块数N_Tx ^SSB＝8个，且传输的同步信号块索引为{0,1,2,3,4,5,6,7}。设无线资源控制信息中ssb-perRACH-OccasionAndCB-PreamblesPerSSB字段取值为1/4，因此，1个SSB与4个连续的随机接入时机相关联。设无线资源控制信息中的msg1-FDM字段取值为4，因此，一个随机接入配置周期中频域的随机接入时机数为4。进一步地，若一个随机接入配置周期中时域的随机接入时机数为4，则可知一个随机接入配置周期中的随机接入时机数为4(频域随机接入时机个数)*4(频域随机接入时机个数)＝16个。根据上述假设可知，完成一次SSB完整映射所需要的随机接入时机数为8(SSB个数)*4(1个SSB关联的随机接入时机个数)＝32个。因此，一个随机接入关联周期包含2个随机接入配置周期。图8为SSB和RO之间关联关系的映射图。Referring to FIG8 , FIG8 is a schematic diagram of a first example according to the fourth embodiment. Assume that the ssb-PositionsInBurst field in the radio resource control information is set to "11111111", therefore, the number of synchronization signal blocks actually transmitted within 5ms is N _Tx ^SSB = 8, and the transmitted synchronization signal block index is {0,1,2,3,4,5,6,7}. Assume that the ssb-perRACH-OccasionAndCB-PreamblesPerSSB field in the radio resource control information is set to 1/4, therefore, 1 SSB is associated with 4 consecutive random access opportunities. Assume that the msg1-FDM field in the radio resource control information is set to 4, therefore, the number of random access opportunities in the frequency domain in a random access configuration period is 4. Further, if the number of random access opportunities in the time domain in a random access configuration period is 4, it can be known that the number of random access opportunities in a random access configuration period is 4 (number of random access opportunities in the frequency domain) * 4 (number of random access opportunities in the frequency domain) = 16. According to the above assumptions, the number of random access opportunities required to complete a complete SSB mapping is 8 (number of SSBs) * 4 (number of random access opportunities associated with 1 SSB) = 32. Therefore, a random access association cycle includes 2 random access configuration cycles. Figure 8 is a mapping diagram of the association relationship between SSB and RO.

参照图13，图13为根据第六实施例示出的第一示例示意图，如图13所示，基于无线资源控制信息确定第一随机接入配置，根据第一随机接入配置及下行链路控制信息中的随机接入配置索引字段确定第二随机接入配置，根据第二随机接入配置确定随机接入时机。对于FR1和FDD，采用协议38.211中的Table 6.3.3.2-2确定随机接入配置周期。设PUSCH的子载波间隔为15KHz。若无线资源控制信息中的prach-ConfigurationIndex取值为16，则根据协议可知终端设备在n_SFNmod1＝0的系统帧(x＝1,y＝0。即n_SFNmod1＝0,1,2,...的系统帧)的子帧1上传输格式0的前导码。因此，基于上述无线资源控制信息中的随机接入配置索引字段确定的随机接入配置周期为10ms。若当前服务小区的终端设备数量减少和/或终端设备的业务频度降低，则网络设备可以在发送给终端设备的DCI中的prach-ConfigurationIndex字段配置为9。若DCI中的prach-ConfigurationIndex字段取值为9，则根据协议可知终端设备在n_SFNmod4＝1的系统帧(x＝4,y＝1。即n_SFNmod4＝1,5,9,...的系统帧)的子帧4上传输格式0的前导码。因此，根据下行链路控制信息中的随机接入配置索引字段确定随机接入配置周期为40ms。进而，终端设备的随机接入配置周期由10ms变为40ms。若当前服务小区的终端设备数量进一步减少和/或终端设备的业务频度进一步降低，则网络设备可以在发送给终端设备的DCI中的prach-ConfigurationIndex字段配置为4。若DCI中的prach-ConfigurationIndex字段取值为4，则根据协议可知终端设备在n_SFNmod8＝1的系统帧(x＝8,y＝1。即n_SFNmod8＝1,9,...的系统帧)的子帧1上传输格式0的前导码。因此，根据下行链路控制信息中的随机接入配置索引字段确定随机接入配置周期为80ms。进而，终端设备的随机接入配置周期由40ms变为80ms。因此，根据当前服务小区的终端设备的数量和/或终端设备的业务频度，图13展示了，终端设备的随机接入配置周期由10ms-->40ms-->80ms。Referring to Figure 13, Figure 13 is a schematic diagram of a first example according to the sixth embodiment. As shown in Figure 13, a first random access configuration is determined based on the radio resource control information, a second random access configuration is determined based on the first random access configuration and the random access configuration index field in the downlink control information, and a random access timing is determined based on the second random access configuration. For FR1 and FDD, the random access configuration period is determined using Table 6.3.3.2-2 in protocol 38.211. Assume that the subcarrier spacing of PUSCH is 15KHz. If the value of prach-ConfigurationIndex in the radio resource control information is 16, it can be known from the protocol that the terminal device transmits a preamble of format 0 on subframe 1 of a system frame of n _SFN mod1＝0 (x＝1, y＝0. That is, a system frame of n _SFN mod1＝0,1,2,...). Therefore, the random access configuration period determined based on the random access configuration index field in the above radio resource control information is 10ms. If the number of terminal devices in the current service cell decreases and/or the service frequency of the terminal devices decreases, the network device can configure the prach-ConfigurationIndex field in the DCI sent to the terminal device to 9. If the value of the prach-ConfigurationIndex field in the DCI is 9, it can be known according to the protocol that the terminal device transmits the preamble of format 0 on subframe 4 of the system frame of n _SFN mod4＝1 (x＝4, y＝1. That is, the system frame of n _SFN mod4＝1,5,9,...). Therefore, the random access configuration period is determined to be 40ms according to the random access configuration index field in the downlink control information. Furthermore, the random access configuration period of the terminal device changes from 10ms to 40ms. If the number of terminal devices in the current service cell further decreases and/or the service frequency of the terminal device further decreases, the network device can configure the prach-ConfigurationIndex field in the DCI sent to the terminal device to 4. If the prach-ConfigurationIndex field in the DCI takes a value of 4, then according to the protocol, the terminal device transmits a format 0 preamble in subframe 1 of a system frame of n _SFN mod8=1 (x=8, y=1. That is, a system frame of n _SFN mod8=1,9,...). Therefore, the random access configuration period is determined to be 80ms according to the random access configuration index field in the downlink control information. Furthermore, the random access configuration period of the terminal device changes from 40ms to 80ms. Therefore, according to the number of terminal devices in the current service cell and/or the service frequency of the terminal device, Figure 13 shows that the random access configuration period of the terminal device changes from 10ms-->40ms-->80ms.

通过本实施例技术方案，具体通过下行链路控制信息中的新增的随机接入配置索引字段实时调整当前随机接入配置周期，使随机接入配置周期的持续时长更符合服务小区的终端设备的数量和/或终端设备的业务频度的需求，且提高了配置随机接入配置周期的灵活性。Through the technical solution of this embodiment, the current random access configuration period is adjusted in real time through the newly added random access configuration index field in the downlink control information, so that the duration of the random access configuration period is more in line with the number of terminal devices in the service cell and/or the service frequency requirements of the terminal devices, and the flexibility of configuring the random access configuration period is improved.

During the active time of the cell DRX, the terminal device determines the first random access configuration according to the random access configuration index field in the radio resource control information, and determines the random access timing according to the first random access configuration.
