为了使得本申请更加的清楚，首先对本申请涉及到的部分概念做简单介绍。
1、系统信息(system information，SI)
在新空口(New Radio,NR)中，SI可以包含一个主系统信息块(master information block，MIB)和若干系统信息块(system information block，SIB)，例如，SIB1、SIB2、SIB3等。
MIB可以包含小区禁止状态信息和进一步接收系统信息所要的小区的基本物理层信息。例如，MIB在广播信道(broadcast channel，BCH)上周期性广播。其中MIB中可以包含下列两个字段，具体内容可以参考3GPP TS 38.331:"NR；Radio Resource Control(RRC)；Protocol specification"：
(1)小区禁止状态(cellBarred)字段，其取值为“barred”意味着小区被禁止。
例如，cellBarred ENUMERATED{barred,notBarred}。
(2)同频重选(intraFreqReselection)字段，当小区或最高等级小区(highest ranked cell)被禁止或被UE禁止，用于控制同频小区的选择/重选。例如，当同频重选字段取值为允许，当该小区被禁止或被UE视为禁止，UE允许选择或重选与该小区同频的小区。
例如，intraFreqReselection ENUMERATED{allowed,notAllowed}。
SIB1可以包含其他系统信息块的调度信息，并包含初始访问所需的信息。例如，SIB1在下行共享信道(downlink shared channel，DL-SCH)上周期性广播或在DL-SCH 上以专有信令的方式发送给连接态UE。
2、NR中小区驻留判断
在NR中，在空闲态UE、非活动态UE或T311正在运行的连接态UE接收到第一小区的SIB1之后，UE需判断是否在第一小区上驻留。若不满足驻留条件，UE不能在该小区驻留，其中驻留条件可以包括以下至少一项：
①UE是否支持第一小区对应的频带band。
②UE是否支持第一小区对应的频带band的发射要求。
③UE支持的信道带宽是否满足部分带宽(bandwidth part，BWP)相关的条件。
其中，针对驻留条件③，可以包括以下：
UE支持的信道带宽大于等于第一小区的初始下行BWP的带宽，且，小于等于第一小区的载波带宽；且，
UE支持的信道带宽大于等于第一小区的初始上行BWP的带宽，且，小于等于第一小区的载波带宽。
3、BWP
BWP也可以称为带宽部分。
一个小区的总小区带宽的一个子集被称为一个BWP。NR R15中，网络设备可以给终端设备配置多个BWP，但终端设备只能工作在一个BWP上，即active BWP或initial BWP(初始BWP)。
以上，为本申请实施例所涉及到的部分概念的简单介绍。
本申请中，第一信息对应的第一条件可以理解为第一信息相关的第一条件。
本申请中，第二信息对应的第二条件可以理解为第二信息相关的第二条件。
本申请中，频率可以理解/替换为频点。
本申请中，获取可以理解/替换为确定或接收。
本申请中，不选择或重选可以理解/替换为不选择或不重选。
需要说明的是，本文以BWP进行说明，但并不限定其名称一定为BWP，也可以是其他名称。例如，BWP可以理解为小区带宽的子集，或，频率范围。例如，BWP可以理解为小区带宽的一部分，小区频率的一部分。或小区带宽包含BWP。例如，BWP也可以等于小区带宽。
本申请中，不允许可以理解/替换为禁止。例如，不允许同频重选可以理解为禁止同频重选。
本申请中，小区被视为禁止可以理解/替换为小区被确定被禁止；或，UE确定小区被禁止。
本申请中，频段可以理解/替换为band，或，frequency band。
本申请中，视为可以理解/替换为确定、确定为。
在现有技术中，对于一个小区，不满足驻留条件，UE不能在该小区驻留，UE会将该小区视为禁止，且会将同频重选视为禁止。综上可知，驻留条件①和驻留条件②都是特定于频段band或频率的条件，若由于驻留条件①和驻留条件②不满足，UE确定不能在该小区上驻留，那么说明UE也不能在与该小区同频的小区上驻留，那么禁止同频重选是合理的，其也避免了UE在同频小区上进行无意义的尝试。但是，驻留 条件③并不是特定于频段band或频率的条件，若由于驻留条件③不满足，UE确定不能在该小区上驻留，并不代表该频点上的其他小区也不能驻留，所以直接禁止同频重选是不合理的，其导致UE可能会错过该小区同频的小区，会影响UE的接入小区的性能。例如，假设UE支持的信道带宽:100,80,40,20MHz，同一频点下的小区1和小区2的载波带宽和初始BWP(以初始下行BWP为例说明)的信息不同，具体如下：
小区1：载波带宽(Carrier bandwidth)为90MHz，初始下行BWP的带宽为90MHz。UE支持的100M信道带宽大于小区的载波带宽，UE支持的80,40,20M信道带宽小于小区的初始下行BWP的带宽，所以，UE不能在这个小区上驻留。
小区2：载波带宽为90MHz，初始下行BWP的带宽为40MHz。UE支持的80M和40M的信道带宽小于小区的载波带宽，且大于小区的初始下行BWP的带宽，UE能在这个小区上驻留。
所以，若由于不满足驻留条件③，UE不能在小区1上驻留，若直接禁止同频重选，将会导致UE错过同频上的小区2(小区2是可以驻留的)。
为了解决上述问题，本申请实施例提供的一种用于小区选择或重选的方法，该方法包括：用户设备UE获取第一小区对应的不特定于频段band或频率的第一信息。UE不满足第一信息对应的用于确定UE是否能够接入第一小区的第一条件，UE选择或重选与第一小区同频的小区。这样，UE可以接入第一小区同频的小区，提升UE接入小区的性能。例如，可以加快小区选择/重选的过程。例如，可以加速初始接入的过程。例如，可以节省UE功耗。
以下实施例中的方法均可以在具有上述硬件结构的设备(如图1中的终端设备130、终端设备140和终端设备150)中实现。
图3为本申请实施例提供的一种用于小区选择或重选的方法的流程示意图。如图3所示，该方法可以包括：
S301、用户设备UE获取第一小区对应的第一信息。
例如，第一信息不特定于频段band或频率。
例如，UE可以包括以下任一种或任几种：空闲态UE(idle UE)、非活动态UE(inACTVIE UE)、T311正在运行的连接态UE。
该“第一信息不特定于频段band或频率”，可以理解为第一信息不是限定/不受限于频段band或频率的信息，或，理解为第一信息不是频段或频率粒度的信息。
例如，第一信息不是限定/不受限于频段band或频率的信息可以理解为：第一信息不是频段band或频率相关的信息。
例如，第一信息不是频段或频率粒度的信息可以理解为：同一频段或频率下的不同小区对应的第一信息不一定相同或不一定完全相同或可能不同。
示例性的，该第一信息可以用于指示以下任一项或多项：第一小区对应的初始下行BWP的信息，第一小区对应的初始上行BWP的信息，第一小区对应的载波带宽。
初始下行BWP的信息可以包括以下任一项或多项：初始下行BWP的带宽、初始下行BWP的位置、初始下行BWP对应的第一子载波间隔(subcarrier spacing，SCS)。初始下行BWP的信息还可以包括其他内容，本申请不限定。

示例性的，初始下行BWP的频域位置可以包括以下任一项或多项：初始下行BWP的中心频点，初始下行BWP开始频点(例如，初始下行BWP的下边界/左边界)，初始下行BWP的终止/结束频点(例如，初始下行BWP的上边界/右边界)。
初始上行BWP的信息可以包括以下任一项或多项：初始上行BWP的带宽、初始上行BWP的位置、初始上行BWP对应的第二子载波间隔(subcarrier spacing，SCS)。初始上行BWP的信息还可以包括其他内容，本申请不限定。
示例性的，初始上行BWP的位置可以包括初始上行BWP的频域位置。
示例性的，初始上行BWP的频域位置可以包括以下任一项或多项：初始上行BWP的中心频点，初始上行BWP开始频点(例如，初始上行BWP的下边界/左边界)，初始上行BWP的终止/结束频点(例如，初始上行BWP的上边界/右边界)。
例如，载波带宽为针对初始下行BWP对应的第一SCS的载波带宽，或，针对初始上行BWP对应的第二SCS的载波带宽。本申请中，可选的，载波带宽可以理解为小区带宽。
需要说明的是，该第一信息中指示的信息并不局限于在第一信息中指示，也可以包含在其他信息中，本申请仅以第一信息为例进行描述，本申请并不限定一定包含在同一个信息中。
该第一信息可以为但不限定于基站向UE发送的SI。示例性的，该第一信息可以为SI中的SIB1或承载/包含在SIB1中。
在一种可能的实现中，S302、不满足第一信息对应的第一条件，UE选择或重选与第一小区同频的小区。

在一些实施例中，图4为本申请实施例提供的又一种用于小区选择或重选的方法的流程示意图。如图4所示，本申请实施例提供的一种应用小区选择或重选的方法，该方法还可以包括：
S401、不满足第一条件或由于不满足第一条件，UE确定在第一频率上的N个小区或至少N个小区或至多N个小区或第N个小区不能接入，N为大于等于1的正整数。
小区不能接入可以理解为小区被禁止或被视为禁止；或，小区不能驻留。
例如，N个小区可以为与第一频率上信号强度最强的N个小区。
例如，第N个小区可以理解为：第一频率上排名第N的小区，或第一频率上排名第N高的小区。
例如，第N个小区可以为第一小区。
该N个小区可以是基站配置的，或预配置的，或协议规定的，或UE确定的，在此不做具体限定。
“UE确定在第一频率上的N个小区或至少N个小区或至多N个小区不能接入”或“不满足第一条件或由于不满足第一条件，UE确定在第一频率上的N个小区或至少N个小区或至多N个小区不能接入”可以包括/理解为：N个小区或至少N个小区或至多N个小区中的每个小区均由于不满足第一条件被禁止或被视为禁止；或，N个小区或至少N个小区或至多N个小区中的部分小区(例如，排名最高的小区被禁止)由于不满足第一条件被禁止或被视为禁止。
可选的，不满足第一条件或由于不满足第一条件，UE确定在第一频率上的N个小区或至少N个小区或至多N个小区不能接入可以包括：满足第三条件，由于不满足第一条件，UE确定在第一频率上的N个小区或至少N个小区或至多N个小区或第N个小区不能接入。
S402、UE将第一频率确定/视为低优先级或最低优先级的频率，或者，UE不选择或重选与第一小区同频的小区，或，UE不选择或重选第一频率的小区。
“UE不选择或重选第一频率的小区”相关的解释可以参考“UE不选择或重选与第一小区同频的小区”，将“与第一小区同频的小区”替换为“第一频率的小区”进行理解即可，此处不再赘述。
可选的，S402具体可以包括以下任一项或多项：UE将第一频率确定/视为低优先级或最低优先级(的频率)长达第四时长，UE将第一频率确定/视为低优先级或最 低优先级(的频率)最长长达第四时长，UE不选择或重选与第一小区同频的小区长达第四时长，UE不选择或重选与第一小区同频的小区最长长达第四时长。
第四时长可以是网络设备配置的，或预配置的，或协议定义的，或UE在出厂时设置好的，本申请不限定。例如，第四时长可以是300秒。
示例性的，UE确定第一频率上的N个小区或至少N个小区或至多N个小区不能接入后，UE可以将第一频率视为最低优先级频率，并持续300秒；或者，UE在300秒内不选择或不重选第一频率上的小区。
例如，由于不满足第一条件，排名最高的小区或最佳小区不能驻留/不能介入/不是用于重选的候选小区，UE考虑同频上的排名第二高的小区用于小区重选，然而，如果由于不满足第一条件，该频率上排名第二高的小区也不适合接入，UE可以将该频率视为最低优先级最长300秒，或，UE可以排除与第一小区(或被禁止的小区)同频的小区作为小区选择/重选的候选小区长达300秒。
本申请实施例通过限定UE尝试接入的小区数量，可以避免UE一直在第一频率上尝试接入，提升UE接入小区的效率和性能。
需要说明的是，S401和S402可以作为单独的实施例，不依赖于S301至S306；也可以和S301至S306中任一个或多个相结合。需要说明的是图3所述的实施例可以分别作为单独的实施例，也可以作为一个整体的实施例。
本申请实施例中的各个方案在不矛盾的前提下，均可以进行结合。
