以及，还可以实现RRC层或者PHY层根据所述MAC指示的提供请求，向MAC层提供所述信号质量测量结果信息，从而达到MAC需要信号质量测量结果信息时，及时得到，以提高选择波束的时效性。
可选的，RRC层或者PHY层提供所述信号质量测量结果信息中，如果是由RRC层提供，则RRC层可以自行决定向MAC层提供所述信号质量测量结果信息。若是PHY层提供，则所述PHY层向所述MAC层提供所述信号质量测量结果信息，或者所述PHY层根据所述RRC层的指示向所述MAC层提供所述信号质量测量结果信息。其中，所述PHY层向所述MAC层提供所述信号质量测量结果信息可以是PHY层自行决定向MAC层提供。
例如：RRC层指示PHY层在进行随机接入资源选择前提供信号质量测量结果信息，则PHY层在进行随机接入资源选择前向MAC层提供信号质量测量结果信息。或者RRC层指示PHY层周期性提供信号质量测量结果信息，则PHY层周期性向MAC层提供信号质量测量结果信息。
由于PHY层可以根据RRC层的指示向MAC层提供信号质量测量结果 信息，从而简化PHY层实体。
另一种实施方式中，上述根据所述至少两个波束的信号质量测量结果信息，选择至少一个波束，包括：
RRC层或者PHY层根据所述至少两个波束的信号质量测量结果信息，选择至少一个波束，并指示给所述MAC层。
该实施方式中，可以实现在RRC层或者PHY层选择出上述至少一个波束，这样可以减少协议层之间的交互，以简化发起随机接入过程的流程。
作为一种可选的实施方式中，若所述获取的配置信息包括信号质量测量门限值，则所选择的所述至少一个波束的测量结果等于或者超过所述信号质量测量门限值，以及满足预设测量条件。具体可以是在所述至少两个波束中选择测量结果等于或者超过所述信号质量测量门限值，且满足预设测量条件的至少一个波束；或者
若所述获取的配置信息未包括信号质量测量门限值，则所述至少一个波束满足预设测量条件，具体可以是在所述至少两个波束中选择满足预设测量条件的至少一个波束。
该实施方式中，可以实现根据上述预设测量条件，以及上述信号质量测量门限值来选择上述至少一个波束，从而保证选择出的波束的信号测量信号是较好或者最好的，从而提高随机接入的成功率。
当然，在一些实施方式中，可以仅根据上述信号质量测量门限值选择至少一个波束，而可以不考虑上述预设测量条件，从而可以达到选择信号质量较好或者最好的波束，以提高随机接入的成功率。
其中，上述预设测量条件可以是预先配置的，具体可以是，协议中预先定义的，或者网络侧预先配置的。其中，所述预设测量条件可以包括如下一项或者多项：
检测到对应的参考信号、测量结果为有效测量结果和处于下行同步状态；
其中，每个波束各自对应的一个参考信号。
由于每个波束各个对应一个参考信号，例如：SSB或者CSI-RS，这样通过上述预设测量条件，可以实现选择出的波束是能够检测到对应的参考信号的，以保证选择出的波束对应的参考信号是可以检测到的，这样在使用该波 束发起随机接入过程的成功率比较高。
另外，本实施例中，测量结果是存在时效性的，即在有效时间内为可用的测量结果，因为，用户终端可以进行多次测量，每个测量的测量结果只在特定时间内是有效，例如：第n测量的测量结果，在第n+1测量之前是有效，或者在第n+1测量之后的特定时间内是有效。
这样通过上述预设测量条件，可以保证选择出的波束的测量结果是有效的，从而可以更加准确地选择出适合的波束。
另外，上述处于下行同步状态可以是，波束与网络侧是下行同步的，这样保证选择出的波束是下行同步，从而提高随机接入的成功率。
需要说明的是，由于上述预设条件可以包括上述三项中的一个或者多项，则选择出的波束可以满足上述多项，例如：选择出的波束是，检测到该波束对应参考信号，且是处于下行同步状态的波束。这样可以更进一步提供随机接入的成功率。
可选的，所述获取的配置信息还包括测量结果类型和测量结果对应的参考信号类型中的至少一项，则上述测量结果包括：
所述测量结果类型的测量结果；或者
所述参考信号类型的测量结果；或者
所述参考信号类型的测量结果中的所述测量结果类型的测量结果。
其中，上述参考信号类型的测量结果中的所述测量结果类型的测量结果可以理解为，测量结果是上述参考信号类型的测量结果，以及是上述测量结果类型的测量结果。例如：上述参考信号类型包括SSB，上述测量结果类型为RSRP，则该测量结果为SSB的RSRP。
该实施方式中，可以实现与上述信号质量测量门限值比较的测量结果是特定类型、特定参考信号的测量结果，这样可以提高选择波束的精确度。
另外，需要说明的是，上述测量结果类型和上述信号质量门限值的类型可以根据协议约定或网路配置，且两者是相同的，如信号质量门限值的类型为RSRQ，则用于比较的测量结果类型也为RSRQ。另外，上述测量结果对应的参考信号类型和上述信号质量门限值对应的参考信号类型可以根据协议约定或网路配置，且两者可以相同，如信号质量门限值的类型为SSB，则用 于比较的测量结果的类型也为SSB。
本实施例中，除通过获取不同类型的测量结果提高随机接入的成功率之外，还可以获取特定时间测量结果，以提高测量结果的准确性。例如：所述测量结果包括：
最新的有效测量结果、向网络侧上报测量报告时测量的测量结果、触发随机接入时测量的测量结果、进行随机接入资源选择时测量的测量结果或者进行下行同步时测量的测量结果。
其中，上述最新的有效测量结果可以是有效时间最新的测量结果，具体可以是离发起随机接入的时间最近的有效测量结果，这样可以保证选择波束的测量结果是最新的，以提高选择波束的准确性。
另外，上述向网络侧上报测量报告时测量的测量结果可以保证向网络侧上报的测量结果与选择波束的测量结果是相同的，从而保证网络侧和用户终端测量结果的同步。
其中，非竞争随机接入的过程中触发随机接入可以是用户终端的PHY层接收到网络侧发送的物理下行控制信道(Physical Downlink Control Channel，PDCCH)指示(即Msg0)触发随机接入过程，而随机接入资源选择可以是，用户终端的PHY层通知MAC层发起随机接入过程，用户终端根据Msg0指示的随机接入资源，进行随机接入资源选择。
而在竞争随机接入的过程触发随机接入可以是用户终端的某协议层(如RRC层)指示MAC层触发随机接入过程，而随机接入资源选择可以是，MAC层触发随机接入过程后，MAC层进行随机接入资源选择。
这样通过上述触发随机接入时测量的测量结果、进行随机接入资源选择时测量的测量结果或者进行下行同步时测量的测量结果，可以保证测量结果的及时性，以提高选择波束的准确性。
可选的，若在所述MAC层选择所述至少一个波束，则所述信号质量测量门限值由所述RRC层或者PHY层向MAC层提供。
另外，该实施方式中，PHY层向MAC层可以将信号质量测量结果信息和信号质量测量门限值配置一起给MAC层。其中，该信号质量测量结果信息包括测量结果，以及还可以包括测量结果类型和测量结果对应的参考信号 类型中的至少一项。信号质量测量门限值配置可以包括信号质量测量门限值，以及还可以包括信号质量测量门限值对应的测量结果类型，以及对应的测量结果对应的参考信号类型。
步骤304、MAC层根据所述至少一个波束的随机接入资源配置信息，确定所述至少一个波束的随机接入资源，并在所述确定的随机接入资源上使用对应的波束发起随机接入。
需要说明的是，本实施例中，并不限定在MAC层确定发起随机接入的随机接入资源，也可以是其他协议层确定，并发起，对此本公开实施例不作限定。
作为一种可选的实施方式，每个波束的随机接入资源配置信息包括时间资源配置信息；所述确定的随机接入资源包括：时间最近的随机接入资源。例如：在所述确定的随机接入资源上使用对应的波束发起随机接入，包括：从所述至少一个波束的随机接入资源中选择时间最近的随机接入资源，并在所述选择的随机接入资源上使用对应的波束发起随机接入。
其中，上述时间最近可以理解为，在选择上述至少一个波束的随机接入资源后，在这些随机接入资源中时间离当前时间最近的随机接入资源，或者可以理解为至少一个波束的随机接入资源中时间离确定随机接入资源的时间最近的随机接入资源。当然，上述时间最近的随机接入资源为可用的随机接入资源。
由于每个随机接入资源都有时间资源配置信息，这样可以确定各随机接入资源的时间，从而在步骤303选择出多个波束时，可以选择一个时间最近，以及可用的随机接入资源发起随机接入，以提高接入效率。
作为一种可选的实施方式，若发起随机接入的随机接入资源由MAC层选择，且所述至少一个波束的随机接入资源配置信息由RRC层或者PHY层向MAC层提供。
例如：可以是用户终端在接收到步骤301中的配置信息后，RRC层或者PHY层在MAC层进行随机接入资源选择，向MAC层提供至少一个波束的随机接入资源配置信息。另外，在MAC选择上述至少一个波束的实施方式中，RRC层或者PHY层可以向MAC提供所有波束的随机接入资源配置信息。 而在RRC层或者PHY层选择上述至少一个波束的实施方式中，RRC层或者PHY层可以是在MAC层进行随机接入资源选择前进行选择，并向MAC层提供这至少一个波束的随机接入资源配置信息，当然，在该情况提供所有波束的随机接入资源配置信息也是可以的。
可选的，所述RRC层或者PHY层向所述MAC层提供所述至少一个波束的随机接入资源配置信息；或者
所述RRC层或者PHY层根据所述MAC的指示，向所述MAC层提供所述至少一个波束的随机接入资源配置信息。
其中，上述提供可以是上述RRC层或者PHY层在进行随机接入资源选择前向所述MAC层提供所述至少一个波束的随机接入资源配置信息；或者可以是所述RRC层或者PHY层周期性向所述MAC层提供所述至少一个波束的随机接入资源配置信息。
其中，这里提供随机接入资源配置信息的实施方式可以参见上述描述的提供信号质量测量结果信息的实施方式，此处作不赘述，且可以达到相同有益效果。例如：所述PHY层可以向所述MAC层提供所述至少一个波束的随机接入资源配置信息，或者所述PHY层可以根据所述RRC层的指示向所述MAC层提供所述至少一个波束的随机接入资源配置信息。
本实施例中，在图2所示的实施例的基础上增加了多种可选的实施方式，且可以进一步提高随机接入的成功率。
