- the embodiment of this application will introduce the energy-saving solution under the cooperation of multiple base stations from the perspective of base station transmission.
- gNB1 and gNB2 are base stations covering neighboring cells, where gNB1 covers area 1 and gNB2 covers area 2.
- the coverage area of a base station is affected by many factors, such as the size of the transmit power, the size of the bandwidth, the level of the modulation method, etc.
- the base station can expand the coverage area of the base station while using the same transmission power.
- the peak rate in the cell is limited at this time.

- gNB2 covers the coverage area 1 of gNB1 through the expanded coverage area 1.
- gNB1 can turn off the transmit function.
- the function of turning off the transmission function of gNB1 and turning on the expanded coverage area of gNB2 can be triggered by gNB1.
- gNB1 detects that the total number of online terminal devices in the cell (area 1) is lower than a certain threshold, or the overall throughput is lower than a certain threshold, it can negotiate with gNB2 to turn off the transmission function of gNB1 and enable gNB2 to expand the coverage area.
- online terminal equipment includes terminal equipment in a connected state and/or terminal equipment in an inactive state.
- the consultation process includes:
- gNB1 initiates a request to turn off transmission, and at the same time requests gNB2 to expand the coverage area.
- the response message indicates whether to allow or disallow turning off gNB1 transmission, and whether to agree or not to expand the gNB2 coverage area.
- Whether gNB2 agrees to expand its coverage area is determined by the coverage area of gNB2, that is, the business conditions of terminals in area 2. When there is no high throughput demand in area 2 and/or the number of online terminal devices is small (the judgment threshold and method can be similar to gNB1 ), gNB2 will agree to expand its coverage area.
- the expansion of the coverage area of gNB2 can be achieved by keeping its own transmit power unchanged (for example, reducing the transmit bandwidth, reducing the modulation method, etc.), or by increasing the transmit power.
- Area 3 covers area 1 after gNB2 expands the coverage area.
- gNB2 activates gNB1 to resume the transmitting function.
- gNB2 After gNB2 monitors that the number of online terminals in area 3 has increased to a certain threshold or the overall throughput has increased to a certain threshold, gNB2 initiates exit from the expanded coverage area mode to activate gNB1 to resume transmission function so that gNB1's coverage area 1 and gNB2 coverage area 2 .
- gNB1 Since the transmit power of terminals located in coverage area 1 is usually limited, their transmitted signals are difficult to be received and demodulated by gNB2. Therefore, the following methods can be adopted for the receiving function of gNB1:
- gNB1 retains the function of receiving and demodulating signals transmitted by terminal equipment in area 1.
- gNB1 retains the function of receiving and demodulating signals transmitted by terminal 1 in area 1.
- the downlink signal of terminal 1 will be sent by gNB2 through the downlink DL, and the uplink signal of terminal 1 will be sent by gNB1.
- Uplink UL1 receives, and gNB1 demodulates the received uplink signal.
- the uplink signal of terminal 2 under gNB2 will be received by gNB2 through UL2.
- Method 2 gNB1 retains the function of receiving signals transmitted by terminal equipment in area 1, and the demodulation function is performed by gNB2.
- gNB1 receives the transmitted signal from the terminal device in area 1 and transparently forwards it to gNB2, and gNB2 demodulates it.
- gNB2 After gNB2 expands the downlink coverage, it can cover area 1, but the transmit power of terminal 1 is relatively small and difficult to be received and demodulated by gNB2. Therefore, through the method described in Figure 13, gNB1 receives the uplink signal of terminal 1 and forwards the received uplink signal to gNB2, which is equivalent to expanding the uplink coverage area of terminal 1.
- the air interface between terminal 1 and gNB1 uses uplink (UL) 1.
- gNB1 can forward the uplink signal of terminal 1 through the air interface or through the interface between base stations.
- the interface between base stations may be an Xn interface.
- the carrier frequency of UL1 that is, the uplink carrier frequency of terminal 1, may be the same as or different from the uplink carrier frequency of gNB2.
- the uplink carrier frequency of terminal 1 is the same as the uplink carrier frequency of gNB2, and gNB1 can be transparent to terminal 1.
- gNB1 and gNB2 complete the negotiation of gNB1 turning off the transmission function and gNB2 expanding the coverage area, gNB1 will be used as the uplink relay base station of gNB2.
- Terminal 1 accesses the gNB2 base station through gNB1, and finally maintains uplink and downlink connections with gNB2.
- the uplink carrier frequency of terminal 1 is different from that of gNB2.
- gNB1 can transparently forward the uplink signal of terminal 1 to gNB2.
- gNB2 is required to have the ability to receive and demodulate the UL1 frequency.
- gNB1 needs to convert the frequency of the received uplink signal to the uplink frequency of gNB2.
- gNB1 When the reception of gNB1 is combined with the transmission of gNB2 to provide uplink and downlink services for terminal 1, the relationship between gNB1 and gNB2 can be as follows:
- gNB1 serves as the anchor base station of terminal 1.
- gNB1 configures gNB2 as the downlink carrier base station of terminal 1. All downlink signals of terminal 1 are transmitted or forwarded by gNB2, and all uplink signals are received by gNB1.
- the anchor base station is responsible for signaling connection control between the terminal and the base station.
- terminal 1 when terminal 1 moves to an area other than area 1 in area 3 after gNB2 expands the coverage area, the anchor base station of terminal 1 will be triggered to switch from gNB1 to gNB2.
- Terminal 1 needs to initiate uplink random access on gNB2, and gNB2 will subsequently provide uplink services and downlink services.
- gNB2 serves as the anchor base station of terminal 1, and gNB2 configures gNB1 as the uplink carrier base station of terminal 1. All downlink signals of terminal 1 are transmitted by gNB2, and all uplink signals are received by gNB1.
- gNB2 will provide uplink and downlink services in the future, when gNB2 does not support the carrier frequency of UL1, gNB2 needs to reconfigure the uplink carrier of terminal 1 to switch from gNB1 to gNB2.
- gNB1 provides uplink services for terminal 1 and switches to gNB2 providing uplink services for terminal 1.
- the methods for switching the uplink service of terminal 1 from gNB1 to gNB2 include:
- gNB1 When the anchor base station is gNB1, gNB1 knows its transmit power situation through the power headroom (PHR) reported by terminal 1. When the transmit power of terminal 1 is not enough to support the uplink service, for example, the uplink signal received by gNB1 If the SINR is too low, gNB1 will instruct terminal 1 to initiate random access on gNB2, and gNB2 will perform uplink and downlink service transmission.
- PHR power headroom
- gNB1 When the anchor base station is gNB2, gNB1 can know its transmit power through the PHR reported by terminal 1. When the transmit power of terminal 1 is not enough to support the uplink service, for example, the SINR of the uplink signal received by gNB1 is too low, etc., gNB1 will Instruct gNB2 to reconfigure the uplink carrier of terminal 1, and then gNB2 will transmit the uplink and downlink services.
- gNB1 (the anchor base station is gNB1) or gNB2 (the anchor base station is gNB2) configures terminal 1 to measure the downlink signal strength of gNB2. When the downlink signal strength is higher than a certain threshold, terminal 1 initiates random access on gNB2 (anchor base station When the base station is gNB1) or gNB2 reconfigures the uplink carrier of terminal 1 (when the anchor base station is gNB2), and gNB2 performs uplink and downlink service transmission.
- gNB2 and gNB3 achieve coverage of gNB1's coverage area 1 through expanded coverage areas, namely expanded coverage area 2 and expanded coverage area 3.
- Terminals in coverage area 1 may be in the expanded coverage area of gNB2.
- Coverage area 2 may also be in gNB3's expanded coverage area 3.
- gNB1 needs to determine whether the terminal is located in the expanded coverage area of gNB2 or the expanded coverage area of gNB3.
- the negotiation process is as follows:
- gNB1 When gNB1 detects that the number of online terminals in area 1 is lower than a certain threshold or the overall throughput in the cell is lower than a certain threshold, gNB1 will negotiate with gNB2 and gNB3 so that gNB1 can turn off the transmission function, and gNB2 and gNB3 Expand the downlink coverage area.
- S22, gNB2 and gNB3 expand the downlink coverage area, and gNB1 configures terminal 1 to measure the downlink signal strength of neighboring cells gNB2 and gNB3 respectively.
- the terminal reports the measured downlink signal strengths of gNB2 and gNB3. Based on this, gNB1 determines the gNB expanded coverage area where terminal 1 is located. As shown in Figure 18, terminal 1 is in the expanded coverage area of gNB3, the uplink signal of terminal 1 is sent to gNB1, and the terminal 1 receives the downlink signal sent by gNB3.
- the content described in scenario one may be applicable to terminal 1, gNB1 and gNB3.
- terminal 1 moves from the expanded coverage area of gNB3 to the expanded coverage area of gNB2, if gNB1 adopts pure reception mode, or reception and demodulation mode, then, if gNB1 is the anchor base station, it will be reconfigured.
- the downlink carrier base station is the downlink carrier of gNB2; when gNB3 is the anchor base station, a handover process will be initiated to switch the anchor base station of terminal 1 from gNB3 to gNB2.
- the size of the sequence numbers of the above-mentioned processes does not mean the order of execution.
- the execution order of each process should be determined by its functions and internal logic, and should not be used in this application.
- the implementation of the examples does not constitute any limitations.

第三目标接入网设备或第四目标接入网设备缩小覆盖区域的方式包括以下至少之一:
提高发射带宽;

降低发射功率。
本申请实施例中,第二接入网设备缩小覆盖区域的方式可基于扩大覆盖区域的方式确定。
本申请实施例提供的无线通信方法,当一接入网设备监测到扩大覆盖范围的小区内的用户数量增加到一定门限或总体吞吐量增加到一定门限后,发起退出扩大覆盖范围模式,激活第一接入网设备的发射功能,恢复第一接入网设备的覆盖区域以及第二接入网设备覆盖区域。
下面,以接入网设备为gNB为例,对本申请实施例提供的无线通信方法进行进一步说明。
基站的发射与接收耗电量跟多种因素有关,比如发射功率的大小、工作带宽的大小、调制方式的高低、是否多载波工作、发射或接收时间长度等。发射功率越低、带宽越小、调制方式越低、单载波工作、发射或接收时间越短都可以降低基站的耗电。本申请实施例将从基站发射的角度出发来介绍多基站协作下的节能方案。
如图13所示,gNB1和gNB2为覆盖邻近小区的基站,其中,gNB1覆盖区域1,gNB2覆盖区域2。基站的覆盖区域受多种因素的影响,比如,发射功率的大小、带宽的大小、调制方式的高低等。基站通过降低发射带宽及调制方式可以在采用同样发射功率的情况下扩大基站的覆盖区域,当然此时小区内的峰值速率是受限的。本申请实施例中,通过扩大单个基站的覆盖区域,实现只采用少数基站就能完成对所有区域的覆盖的方式降低基站功耗。
场景一、如图14所示,gNB2通过扩大覆盖区域后的扩大的覆盖区域1实现对gNB1的覆盖区域1的覆盖
在图14中,gNB1可以关闭发射功能。
gNB1关闭发射功能与gNB2开启扩大覆盖区域的功能需要基于一定的条件判断,采用这种方式虽然能节省基站的耗电,但同时带来了总体吞吐量的下降。因此对于小区内具有高速率业务时,不宜采用这种降低基站功耗的方式。
gNB1关闭发射功能以及开启gNB2的扩大覆盖区域的功能可以由gNB1触发。当gNB1监测到小区内(区域1)的总体在线终端数设备的量低于一定门限,或总体吞吐量低于一定门限时,可以与gNB2协商关闭gNB1的发射功能以及开启gNB2的扩大覆盖区域的功能。其中,在线终端设备包 括处于连接态的终端设备和/或处于非激活态的终端设备。
协商过程,包括:
S11、gNB1发起关闭发射的请求,同时请求gNB2扩大覆盖区域。
S12、gNB2反馈响应消息。
该响应消息指示允许或不允许关闭gNB1发射,以及同意或不同意扩大gNB2覆盖区域。
gNB2是否同意扩大其覆盖区域受gNB2的覆盖区域即区域2内终端的业务情况确定,当区域2内没有高吞吐量需求和/或在线终端设备的数量较少时(判断门限及方法可类似gNB1),gNB2将同意扩大其覆盖区域。
gNB2扩大覆盖区域可以在保持自身发射功率不变的情况下实现(比如:降低发射带宽、降低调制方式等),也可以通过增大发射功率的方式来实现。
S13、gNB1关闭发射功能。
S14、gNB2扩大覆盖区域。
gNB2扩大覆盖区域后的区域3涵盖区域1。
S15、gNB2激活gNB1恢复发射功能。
gNB2监测到区域3内的在线终端的数量增加到一定门限或总体吞吐量增加到一定门限后,gNB2发起退出扩大覆盖区域模式,以激活gNB1恢复发射功能使得gNB1的覆盖区域1以及gNB2覆盖区域2。
位于覆盖区域1内的终端,由于其发射功率通常比较有限,其发射信号难以被gNB2接收并解调,因此,对于gNB1的接收功能可采取下述方式:
方式1、gNB1保留对区域1内终端设备的发射信号的接收及解调功能
如图15所示,gNB1保留对区域1内终端1的发射信号的接收及解调功能,此时,终端1的下行信号将由gNB2通过下行链路DL进行发送,终端1的上行信号将由gNB1通过上行链路UL1进行接收,且gNB1对接收的上行信号进行解调,gNB2下的终端2的上行信号将由gNB2通过UL2进行接收。
方式2、gNB1保留对区域1内终端设备的发射信号的接收功能,解调功能由gNB2执行。
如图16所示,gNB1接收区域1内终端设备的发射信号后采取透明转发方式给gNB2,由gNB2对其进行解调。
gNB2扩大下行覆盖后可以将区域1涵盖进去,但终端1的发射功率相对较小而难以被gNB2接收解调。因此,通过图13所述方式,gNB1接收终端1的上行信号并将接收的上行信号转发给gNB2,这相当于扩大了终端1的上行覆盖区域。
终端1与gNB1的空口采用上行链路(uplink,UL)1,gNB1将终端1上行信号进行转发可以是空口转发,也可以是通过基站间的接口进行转发。基站间的接口可为Xn接口。
UL1的载波频率即终端1的上行载波频率可以跟gNB2的上行载波频率相同或不同。
终端1的上行载波频率跟gNB2的上行载波频率相同,gNB1可以是对终端1透明的。在gNB1与gNB2完成gNB1关闭发射功能且gNB2扩大覆盖区域的协商后,gNB1将作为gNB2的上行中继基站使用。终端1通过gNB1接入gNB2基站,并最终与gNB2保持上下行连接。
终端1的上行载波频率跟gNB2的上行载波频率不同,gNB1可以将终端1的上行信号透明转发给gNB2,此时,要求gNB2具有接收解调UL1频率的能力。
如果gNB2不具备接收解调UL1的载波频率的能力,需要gNB1将接收的上行信号的频率变换为gNB2的上行频率。
当gNB1的接收与gNB2的发射进行组合来为终端1提供上下行服务时,gNB1与gNB2的关系可以有下述两种:
1、gNB1作为终端1的锚点基站,gNB1将gNB2配置为终端1的下行载波基站,终端1的所有的下行信号都由gNB2进行发射或转发,所有上行信号都由gNB1接收。
锚点基站负责终端与基站的信令连接控制。
在这种关系下,当终端1移动gNB2扩大覆盖区域后的区域3中区域1以外的区域时,将触发终端1的锚点基站从gNB1切换到gNB2。终端1需要在gNB2上发起上行随机接入,后续将由gNB2提供上行服务及下行服务。
2、gNB2作为终端1的锚点基站,gNB2将gNB1配置为终端1的上行载波基站,终端1的所有的下行信号都由gNB2进行发射,所有上行信号都由gNB1接收。
在这种方式下,当终端1移动到区域3中区域1以外的区域时,将不会触发终端1的锚点基站 切换。但由于后续将由gNB2提供上行及下行服务,在gNB2不支持UL1的载波频率的情况下,gNB2需要将终端1的上行载波进行重新配置,以从gNB1切换到gNB2。
在终端1从区域1移动到区域3中区域1以外的区域,触发移动性管理,使得由gNB1为终端1提供上行服务切换为gNB2为终端1提供上行服务。终端1的上行服务从gNB1切换到gNB2的方式包括:
切换方式1、基站指示
当锚点基站是gNB1时,gNB1通过终端1上报的功率余量(power headroom,PHR)知道其发射功率情况,当终端1的发射功率不足以支持上行业务时,比如gNB1接收到的上行信号的SINR过低等,gNB1将指示终端1在gNB2上发起随机接入,并由gNB2进行上行及下行的业务传输。
当锚点基站是gNB2时,gNB1可以通过终端1上报的PHR知道其发射功率情况,当终端1的发射功率不足以支持上行业务时,比如gNB1接收到的上行信号的SINR过低等,gNB1将指示gNB2对终端1的上行载波进行重新配置,之后由gNB2进行上行和下行业务的传输。
切换方式2、终端测量
gNB1(锚点基站是gNB1)或gNB2(锚点基站是gNB2)配置终端1测量gNB2的下行信号强度,当下行信号强度高于一定门限时,终端1在gNB2上发起随机接入(锚点基站是gNB1时)或gNB2对终端1的上行载波进行重新配置(锚点基站是gNB2时),并由gNB2进行上行及下行的业务传输。
场景2、多个基站通过扩大覆盖区域来实现对gNB1区域1的覆盖
如图17所示,gNB2和gNB3通过扩大的覆盖区域即扩大的覆盖区域2和扩大的覆盖区域3实现对gNB1的覆盖区域1的覆盖,覆盖区域1内的终端将可能会处于gNB2的扩大的覆盖区域2也可能会处于gNB3扩大的覆盖区域3。相比于场景一中gNB1始终与gNB2的协商、配置及转发等过程,在图17中gNB1需要根据终端是位于gNB2扩大的覆盖区域还是gNB3扩大的覆盖区域来确定。
协商过程如下:
S21、当gNB1监测到区域1内的在线终端的数量低于一定门限或小区内总体吞吐量低于一定门限时,gNB1将与gNB2和gNB3进行协商,以使得gNB1可以关闭发射功能,gNB2和gNB3扩大下行覆盖区域。
S22、gNB2和gNB3扩大下行覆盖区域,gNB1配置终端1分别测量邻区gNB2和gNB3的下行信号强度。
S23、终端上报测量到的gNB2和gNB3下行信号强度。gNB1基于此确定终端1所处的gNB扩大覆盖区域。如图18所示,终端1处于gNB3的扩大的覆盖区域,终端1的上行信号发送至gNB1,且终端1接收gNB3发送的下行信号。这里,场景一中描述的内容可以适用于终端1、gNB1和gNB3。
当终端1从gNB3的扩大的覆盖区域移动到gNB2的扩大的覆盖区域时,如gNB1采用纯接收方式,或者接收和解调的方式,那么,在gNB1为锚点基站的情况下,将重新配置下行载波基站为gNB2的下行载波;在gNB3为锚点基站的情况下,将发起切换过程,将终端1的锚点基站由gNB3切换到gNB2。
