本申请实施例涉及到的终端还可以称为终端设备，是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端可以是用户设备(user equipment，UE)，UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请实施例中，实现终端的功能的装置可以是终端，也可以是能够支持终端实现该功能的装置。本申请实施例中，以实现终端的功能的装置是终端，以终端是UE为例，描述本申请实施例提供的技术方案。

在无线通信系统中，gNB和UE可以利用空口资源进行无线通信。在一种可能的无线通信系统中，例如5G系统中，空口资源包括频率资源。频率资源可以位于设置的频率范围，频率范围还可以称为频带(band)或频段。在本申请实施例中，频率资源还可以称为频域资源。在频域，频率资源的中心点可以称为中心频点，频率资源的宽度可以称为带宽(bandwidth，BW)。示例性地，图1所示为频率资源的位置示意 图。如图1中所示，频率资源可以为频带内的部分或全部资源，频率资源的带宽为W，中心频点的频率为F。其中，频率资源的边界点的频率分别为F-W/2和F+W/2，还可以描述为，频率资源中最高频点的频率为F+W/2，频率资源中最低频点的频率为F-W/2。在无线通信系统中，用于进行下行通信的频率资源和用于进行上行通信的频率资源可以相同，也可以不相同，本申请不做限制。

示例性地，上述gNB为UE分配频率资源的一种可能的设计可能应用于但不限于以下三个场景：
场景一：大带宽场景
在通信系统中，随着UE业务量的增加和UE数量的增加，系统业务量显著增加，因此，现有通信系统中提出了系统带宽为大带宽的设计，用于提供较多的系统资源，从而可以提供较高的数据传输速率。在系统带宽为大带宽的通信系统中，考虑到UE的成本以及UE的业务量，UE支持的带宽可能小于系统带宽。其中，UE支持的带宽 越大，UE的处理能力越强，UE的数据传输速率可能越高，UE的设计成本可能越高。UE支持的带宽还可以称为UE的带宽能力。示例性地，在5G系统中，系统带宽最大可能为400MHz，UE的带宽能力可能为20MHz、50MHz或100MHz等。在无线通信系统中，不同UE的带宽能力可以相同也可以不同，本申请实施例不做限制。
在系统带宽为大带宽的通信系统中，由于UE的带宽能力小于系统带宽，gNB可以从系统频率资源中为UE配置带宽资源，该带宽资源的带宽小于等于UE的带宽能力。当UE和gNB进行通信时，gNB可以将为UE配置的带宽资源中的部分或全部资源分配给UE，用于进行gNB和UE间的通信。
场景二：多参数场景
在无线通信系统中，例如5G系统中，为了支持更多的业务类型和/或通信场景，提出了支持多种参数的设计。对于不同的业务类型和/或通信场景，可以独立设置numerology。
在一种可能的配置中，gNB可以在系统频率资源中配置多个带宽资源，为该多个带宽资源中的每个带宽资源独立配置numerology，用于在系统频率资源中支持多种业务类型和/或通信场景。其中，不同带宽资源的numerology可以相同，也可以不相同，本申请不做限制。
当UE和gNB进行通信时，gNB可以基于该通信对应的业务类型和/或通信场景确定用于进行通信的numerology A，从而可以基于numerology A为UE配置相应的带宽资源。其中，该相应的带宽资源的numerology被配置为numerology A。当UE和gNB进行通信时，gNB可以将为UE配置的带宽资源中的部分或全部资源分配给UE，用于进行gNB和UE间的通信。
场景三：带宽回退
当UE和gNB进行通信时，gNB可以基于UE的业务量为UE配置带宽资源，用于节省UE的功耗。示例性地，如果UE没有业务，UE可以只在较小的带宽资源中接收控制信息，可以降低UE的射频处理的任务量和基带处理的任务量，从而可以减少UE的功耗。如果UE的业务量较少，gNB可以为UE配置带宽较小的带宽资源，可以降低UE的射频处理的任务量和基带处理的任务量，从而可以减少UE的功耗。如果UE的业务量较多，gNB可以为UE配置带宽较大的带宽资源，从而可以提供更高的数据传输速率。当UE和gNB进行通信时，gNB可以将为UE配置的带宽资源中的部分或全部资源分配给UE，用于进行gNB和UE间的通信。
gNB和UE进行通信时，可以传输参考信号(reference signal，RS)，用于进行信道状态估计，gNB和UE可以基于估计的信道状态匹配地进行数据传输，从而可以提高数据传输速率。其中，信道状态估计还可以简称为信道估计，信道估计还可以描述为信道测量。在本申请实施例中，RS主要用于进行信道估计或信道测量，其还可以称为导频或者其它名称，本申请不做限制。
示例性地，当gNB和UE进行下行数据传输时，gNB向UE发送信道状态信息参考信号(channel state information reference signal，CSI-RS)。UE根据接收到的CSI-RS进行信道估计，UE将估计到的信道状态信息发送给gNB。gNB可以根据该信道状态信息对应的信道状态匹配地为UE发送下行数据，从而可以提高下行数据传输速率。 在本申请实施例中，CSI-RS为gNB向UE发送的参考信号，用于进行下行信道估计或下行信道测量，其还可以称为下行参考信号或者其它名称，本申请不做限制。进一步地，用于进行下行信道估计的参考信号还可以包括小区特定参考信号(cell-specific reference signal，CRS)和下行解调参考信号(demodulation reference signal，DMRS)中至少一个。
再示例性地，当gNB和UE进行上行数据传输时，UE向gNB发送探测参考信号(sounding reference signal，SRS)。gNB根据接收到的SRS进行信道估计，并根据估计到的信道状态确定传输参数，gNB可以将该传输参数发送至UE。UE接收gNB发送的传输参数，根据该传输参数向gNB发送上行数据。通过该设计，可以使UE根据信道状态匹配地为gNB发送上行数据，从而可以提高上行数据传输速率。在本申请实施例中，SRS为UE向gNB发送的参考信号，用于进行上行信道估计或上行信道测量，其还可以称为上行参考信号或者其它名称，本申请不做限制。进一步地，用于进行上行信道估计的参考信号还可以包括上行DMRS。
在后续本申请实施例中，以参考信号是CSI-RS为例对本申请实施例提供的技术方案进行描述。
在无线通信系统中，gNB可以在系统频率资源中为多个UE配置各UE的带宽资源，用于gNB和该多个UE进行数据传输。示例性地，以2个UE为例，该2个UE分别为第一UE和第二UE，gNB可以在系统频率资源中为第一UE和第二UE配置带宽资源。图3所示为gNB为第一UE和第二UE配置的带宽资源的示例图。如图3所示，gNB为第一UE配置的带宽资源为第一带宽资源，为第二UE配置的带宽资源为第二带宽资源，第一带宽资源和第二带宽资源在频域部分重叠。
gNB可以在第一带宽资源中为第一UE发送第一CSI-RS，用于进行第一带宽资源的信道估计，gNB可以根据该信道估计结果和/或第一UE的数据量在第一带宽资源中为第一UE分配资源，gNB和第一UE可以在该分配的资源进行数据传输。其中，UE的数据量还可以称为UE的业务量。示例性地，在时隙n，gNB在第一带宽资源中为第一UE分配的资源为R1_n；在时隙n+1，gNB在第一带宽资源中为第一UE分配的资源为R1_n1。
gNB可以在第二带宽资源中为第二UE发送第二CSI-RS，用于进行第二带宽资源的信道估计，gNB可以根据该信道估计结果和/或第二UE的数据量在第二带宽资源中为第二UE分配资源，gNB和第二UE在该分配的资源进行数据传输。示例性地，在时隙n，gNB在第二带宽资源中为第二UE分配的资源为R2_n；在时隙n+1，gNB在第二带宽资源中为第二UE分配的资源为R2_n1。
如图3所示，在时隙n，gNB为第一UE分配的资源R1_n中可能包括第一带宽资源和第二带宽资源的重叠部分中的资源。如果gNB在时隙n向第二UE发送第二CSI-RS，用于传输第二CSI-RS的资源也可能包括第一带宽资源和第二带宽资源的重叠部分中的资源。此时，第一UE的数据和第二CSI-RS可能冲突，从而可能影响第一UE的数据传输和/或第二CSI-RS的传输。
基于上述分析可以看出，在数据传输时，gNB在系统频率资源中为多个UE配置各UE的带宽资源时，可能造成不同UE的数据间的冲突，从而影响各UE的数据的传 输性能。为了解决该冲突，本申请实施例提供了资源配置方法、装置和系统。进一步地，本申请实施例提供的资源配置方法、装置和系统还可以解决其它类型的数据冲突，本申请不做限制。示例性地，其它类型的冲突可以为以下三种冲突中任一个：
第一种冲突：后向兼容场景中的冲突。在NR的资源中可能传输现有的其它系统的数据，或者在现有的其它系统的资源中可能传输NR的数据，此时NR的数据可能和现有的其它系统的数据间存在冲突。示例性地，现有的其它系统可能为长期演进(long term evolution，LTE)系统、码分多址接入(code division multiple access，CDMA)系统或全球移动通信系统(global system for mobile communications，GSM)。
第二种冲突：前向兼容场景中的冲突。在NR的资源中可能传输未来系统的数据，或者在未来系统的资源中可能传输NR的数据，此时NR的数据可能和未来系统的数据间存在冲突。其中，未来系统还可以称为未来网络、未来演进版本或者其它名称，本申请不做限制。
第三种冲突：多点协作传输中的冲突。在多点协作场景中，一个或者多个基站可以在多个小区和同一个UE进行数据传输，此时，在不同小区传输的数据间可能存在冲突。

401，gNB和UE在资源单元中确定预留资源元素(resource element，RE)，该预留RE包括于预留资源中。其中，该资源单元中频域包括X个资源块(resource block，RB)且时域包括Y个符号，其中，X和Y为正整数。
gNB和UE可以通过预配置的方式确定X和Y中至少一个。
gNB还可以为UE发送资源单元大小配置信令，用于指示X、Y、或X和Y。UE接收资源单元大小配置信令，相应地确定X和Y中至少一个。其中，资源单元大小配置信令用于指示X、Y、或X和Y，其还可以称为别的名称，本申请不做限制。如果资源单元大小配置信令用于指示X，UE根据接收到的资源单元大小配置信令确定X；如果资源单元大小配置信令用于指示Y，UE根据接收到的资源单元大小配置信令确定Y；如果资源单元大小配置信令用于指示X和Y，UE根据接收到的资源单元大小配置信令确定X和Y。
在本申请实施例中，信令可以是高层信令或者物理层信令。高层信令可以为无线资源控制(radio resource control，RRC)信令、广播消息、系统消息或媒体接入控制(medium access control，MAC)控制元素(control element，CE)。物理层信令可以为物理控制信道携带的信令或者物理数据信道携带的信令，其中，物理控制信道携带的信令可以为物理下行控制信道携带的信令、增强物理下行控制信道(enhanced physical downlink control channel,EPDCCH)携带的信令、窄带物理下行控制信道(narrowband physical downlink control channel,NPDCCH)携带的信令或机器类通信物理下行控制信道(machine type communication(MTC)physical downlink control channel，MPDCCH)携带的信令。物理下行控制信道携带的信令还可以称为下行控制信息(downlink control information，DCI)。物理控制信道携带的信令还可以为物理副链路控制信道(physical sidelink control channel)携带的信令，物理副链路控制信道携带的信令还可以称为副链路控制信息(sidelink control information，SCI)。
示例性地，X和Y都等于1。再示例性地，X等于1时Y大于1，Y等于1时X大于1。X等于1时Y大于1，Y等于1时X大于1还可以描述为：X和Y不同时等于1。再示例性地，X和Y都大于1。
402，gNB和UE在预留资源之外的全部或者部分资源中进行数据传输。
示例性地，gNB和UE在预留资源之外的全部或者部分RE中进行数据传输。在本申请实施例中，数据传输包括接收数据和发送数据中至少一个。
在无线通信系统中，例如在基于OFDM的通信系统中，空口资源可以包括频率资源和时域资源。其中，频率资源和时域资源可以组合起来称为时频资源。
频率资源的单位可以为子载波、RB或者资源块组(resource block group，RBG)。其中，一个RBG中可以包括至少一个RB。RB可以为物理资源块(physical resource block，PRB)，也可以为虚拟资源块(virtual resource block，VRB)。
在频域，可用于进行数据传输的资源中包括若干个资源格，一个资源格对应于一个子载波，一个PRB中包括X1个资源格，X1为大于1的整数。示例性地，X1为12。可用于进行数据传输的资源可以为系统频率资源中的部分或全部资源，也可以为带宽资源中的部分或全部资源，本申请不做限制。可用于进行数据传输的资源的带宽可以被称为X2个PRB，X2为大于等于1的整数。对于可用于进行数据传输的资源中的PRB，可以基于频率增加的方向从X3至X3+X2-1为各PRB依次进行编号，得到各PRB的编号值。其中，X3为整数，示例性地，X3等于0。在本申请实施例中，术语“编号值”也可以称作“标识”或“索引”。
可用于进行数据传输的资源中，一个PRB对应一个VRB。VRB可以包括集中式VRB或者分布式VRB。集中式VRB和PRB直接映射，即索引为n VRB的VRB对应的PRB的索引为n PRB，其中n PRB＝n VRB。分布式VRB和PRB通过一定的规则进行映射，该规则可以为本领域技术人员常用的映射方法。示例性地，该映射方法可以为LTE系统3GPP标准协议中的映射方法。
时域资源的单位可以为符号、时隙、微时隙、子帧、帧或其它本领域中常用的时间单元。其中，不同子载波间隔对应的时间单元的长度可以不同。以符号为例，如果第一子载波间隔为Δf，第二子载波间隔为k×Δf，则k个第二子载波间隔对应的符号长度之和可以等于1个第一子载波间隔对应的符号长度。其中，k为大于等于2的整数。
在时频资源中，频域的一个子载波和时域的一个符号可以对应于一个RE。
随着无线通信技术的发展，为了提高数据传输的可靠性和/或提高数据传输速率，引入了多天线技术。在多天线系统中，gNB和UE可以通过多个天线端口进行数据传输，该多个天线端口中的每一个天线端口可以看做一个空间层，每个空间层对应一份空口资源。因此，在多天线系统中，gNB和UE可以在多个空间层传输数据，在多个空间层传输相同的数据时可以提高数据传输的可靠性，在多个空间层传输不同的数据时可以提高数据传输的速率。由于各个天线端口是独立进行数据传输的，因此在设置参考信号时，可以为各天线端口设置其对应的参考信号。
对于一个UE，用于传输该UE的CSI-RS的资源可以配置在该UE的带宽资源中，传输该UE的CSI-RS时使用的numerology可以为该UE的带宽资源的numerology。 其中，UE的带宽资源的numerology可以用于传输UE的数据信道携带的信息，也可以用于传输UE的控制信道携带的信息，还可以用于传输UE的参考信号。其中，数据信道可以是物理层数据信道，控制信道可以是物理层控制信道。在UE的带宽资源的部分或者全部资源中，可以基于CSI-RS图案(pattern)，确定用于传输CSI-RS的RE。
图5所示为一个2天线端口对应的CSI-RS图案的示例。如图5所示，CSI-RS图案对应的资源粒度中包括12个子载波和14个符号，相应地，该资源粒度中包括168个RE，1个RE对应一个子载波和一个符号。在图5所示的CSI-RS图案中，将12个子载波和14个符号对应的资源粒度中的2个RE设置为用于传输CSI-RS的RE。其中，第一个RE为RE(3,0)，3表示该RE所在的子载波的索引，0表示该RE所在的符号的索引；第二个RE为RE(9,0)，9表示该RE所在的子载波的索引，0表示该RE所在的符号的索引。
在可用于进行数据传输的资源中，当CSI-RS图案用于确定传输CSI-RS的RE时，以该CSI-RS图案对应的资源粒度为单位确定用于传输CSI-RS的RE。示例性地，如果CSI-RS图案为图5所示的CSI-RS图案，在可用于进行数据传输的资源中，在每个12个子载波和14个符号对应的资源中，RE(3,0)和RE(9,0)为用于传输CSI-RS的RE。
在实际应用中，CSI-RS图案对应的资源粒度中可以包括任意正整数个子载波和任意正整数个符号，本申请不做限制。在实际应用中，可以将CSI-RS图案对应的资源粒度中的任意RE配置为用于传输CSI-RS的RE，本申请不做限制。示例性地，1个RB频域包括12个子载波，表1所示为在1个RB和14个符号对应的资源粒度中配置的CSI-RS图案。根据该CSI-RS图案，在1个RB和14个符号对应的资源粒度中，用于传输CSI-RS的RE为RE(k,l)，其中，

通过本申请实施例提供的资源配置方法，可以解决不同UE的数据间的冲突。以图3为例，在时隙n，第一UE的数据和第二UE的CSI-RS可能冲突。为了解决该冲突，可以在第一UE的带宽资源中为第一UE配置预留RE，该预留RE中包括用于传输第二CSI-RS的RE，该预留RE包括于为第一UE配置的预留资源中。在为第一UE配置的预留资源中，gNB和第一UE不进行数据传输，即gNB和第一UE在为第一UE配置的预留资源之外的全部或部分RE中进行数据传输。此时，第一UE的数据和第二UE的CSI-RS不会冲突。其中，第一UE的带宽资源的numerology和第二UE的带宽资源的numerology可以相同，也可以不相同，本申请不做限制。
图6所示为通过本申请实施例提供的资源配置方法解决不同numerology的UE间的冲突的第一个示例图。如图6所示，一个RB中包括12个子载波，第一UE的带宽资源的子载波间隔为15kHz，第二UE的带宽资源的子载波间隔为60kHz，传输第二UE的CSI-RS的子载波间隔为该UE的带宽资源的子载波间隔。其中，4个15kHz的子载波的宽度之和等于1个60kHz的子载波的宽度，4个60kHz的符号长度之和等于1个15kHz的符号长度。根据第二UE的CSI-RS图案，在15kHz对应的4个RB和1个符号组成的一个资源单元中，第二UE可能使用60kHz在一个RE传输CSI-RS。

在本申请实施例提供的方法中，为UE配置的资源单元对应的子载波间隔可以和该UE的带宽资源的子载波间隔相同，也可以和该UE的带宽资源对应的子载波间隔不同，本申请不做限制。其中，资源单元对应的子载波间隔还可以描述为资源单元中包括的RB对应的子载波间隔、资源单元中包括的符号对应的子载波间隔、或者资源单元中包括的RE的子载波间隔。为UE配置的资源单元对应的子载波间隔和该UE的带宽资源对应的子载波间隔相同时，可以减少UE维护的numerology的个数，降低UE实现复杂度。为UE配置的资源单元对应的子载波间隔和UE的带宽资源对应的子载波间隔不同时，可以使基站根据其对预留资源的使用需求灵活配置资源单元的子载波间隔， 可以降低信令开销。示例性地，在图6中，基站可以在第一UE的预留资源中传输第二UE的CSI-RS，为第一UE配置的预留资源对应的子载波间隔可以为第二UE的CSI-RS的子载波间隔。
可选地，为UE配置的资源单元对应的子载波间隔为当前频段支持的最小子载波间隔。示例性地，对于6GHz以下频段，支持的最小子载波间隔为15kHz；对于6GHz以上频段，支持的最小子载波间隔为60kHz。
可选地，gNB还可以为UE发送信令，通过该信令指示为该UE配置的资源单元对应的子载波间隔。其中，该信令还可以称为资源单元子载波间隔配置信令。
可选地，为UE配置的资源单元对应的子载波间隔可以与传输系统消息使用的子载波间隔相同。
如果gNB通过系统消息为UE指示X和Y中至少一个，则为UE配置的资源单元对应的子载波间隔和传输该系统消息使用的子载波间隔相同。其中，X为资源单元中频域包括RB数，Y为资源单元中时域包括的符号数。
在第一种预留RE确定方法中，根据预留RE图案，当y1大于1时，不同符号中的预留RE对应的子载波可以相同。图10所示为预留RE图案的第一种可能的示例。
如图10(a)所示，资源单元在频域包括2个RB且时域包括14个符号，1个RB中包括子载波0至子载波11共12个子载波。在资源单元中，可以在符号0至符号7中配置预留RE。在符号0至符号7中，各符号中的预留RE对应的子载波相同，均为RB 0的子载波6至RB 1的子载波7。

在第一种预留RE确定方法中，当y1大于1时，不同符号中的预留RE对应的子载波也可以不同。该方法还可以描述为：当y1大于1时，在该y1个符号中，至少2个符号中的预留RE对应的子载波不同。图11所示为预留RE图案的第二种可能的示例，如图11所示，资源单元在频域包括2个RB且时域包括3个符号，其中，1个RB中包括子载波0至子载波11共12个子载波。
可选地，在该y1个符号中，符号y2中的预留RE对应的子载波与符号y3中的预留RE对应的子载波个数不同，y2为大于等于0且小于等于y1-1的整数，y3为大于等于0且小于等于y1-1的整数。如图11(a)所示，在资源单元中，可以在符号0和符号2中配置预留RE。在符号0中，预留RE对应的子载波为：RB 0的子载波3至子载波5、RB 0的子载波10至子载波11、RB 1的子载波0、RB 1的子载波5至子载波 7。在符号2中，预留RE对应的子载波为：RB 0的子载波4和子载波11、和RB 1的子载波6。

其中Δ offset＝2。
在第一种预留RE确定方法中，对于一个UE，可以为该UE配置一个预留RE图案，UE根据该预留RE图案在资源单元中确定预留RE。对于N个UE，可以配置各UE对应的预留RE图案，该N个UE中任意2个UE的预留RE图案可以相同也可以不相同，其中，N为大于等于2的整数。对于该N个UE，也可以配置该N个UE的公共预留RE图案，即该N个UE的预留RE图案相同。示例性地，该N个UE可以为小区中的所有UE或者部分UE。
在第一种预留RE确定方法中，gNB还可以为UE发送参考信号指示和参考信号配置指示。用于指示gNB为UE配置的预留RE。其中，参考信号可以是CSI-RS、解调参考信号(demodulation reference signal，DMRS)或其它参考信号。UE接收参考信号指示和参考信号配置指示，根据参考信号配置指示，从参考信号指示对应的参考信号图案中确定预留RE图案。其中，从参考信号指示对应的参考信号图案中确定预留RE图案还可以描述为：从参考信号指示所指示的参考信号的可用的参考信号图案中确定预留RE图案。示例性地，如果参考信号指示所指示的参考信号为CSI-RS，参考信号指示对应的参考信号图案为CSI-RS图案。
