Description

一种单射频UE射频资源分配方法及装置A single radio frequency UE radio frequency resource allocation method and device

技术领域technical field

本发明涉及移动通信技术领域,尤其涉及一种单射频UE射频资源分配方法及装置。The present invention relates to the technical field of mobile communication, in particular to a method and device for allocating radio frequency resources of a single radio frequency UE.

背景技术Background technique

长期演进(Long Term Evolution,LTE)系统中,为了提升用户的数据传输速率,并减少延迟。在LTE版本10中引入了载波聚合(Carrier Aggregation,CA)技术,即一个用户设备(User Equipment,UE)可以被多个下行和/或上行载波提供服务,以提高UE的数据传输速率。载波聚合技术下的UE可以有两个不同下行载波的服务小区,每个下行载波对应一个上行载波;当然,UE也可以是两个下行载波共享一个上行载波。无论UE具有一个还是多个上行载波,用于上行的物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH)只在面向UE的多个下行小区的主小区(Primary cell,Pcell)的上行载波上存在。因为CA技术中为同一UE服务的两个小区是光纤连接或者是共站的,UE通过Pcell的PUCCH给辅小区(Secondary cell,Scell)发送的信息可以及时的到达Scell,即,Pcell与Scell之间的链接为理想回程线路(backhaul)链接。In a Long Term Evolution (LTE) system, in order to increase the data transmission rate of the user and reduce the delay. In LTE release 10, a carrier aggregation (Carrier Aggregation, CA) technology is introduced, that is, a user equipment (User Equipment, UE) can be served by multiple downlink and/or uplink carriers, so as to improve the data transmission rate of the UE. The UE under the carrier aggregation technology may have two serving cells with different downlink carriers, and each downlink carrier corresponds to an uplink carrier; of course, the UE may also have two downlink carriers sharing one uplink carrier. Whether the UE has one or more uplink carriers, the physical uplink control channel (Physical Uplink Control CHannel, PUCCH) used for uplink is only on the uplink carrier of the primary cell (Pcell) of multiple downlink cells facing the UE exist. Because the two cells serving the same UE in the CA technology are connected by optical fiber or co-sited, the information sent by the UE to the secondary cell (Secondary cell, Scell) through the PUCCH of the Pcell can reach the Scell in time, that is, the connection between the Pcell and the Scell The link between is an ideal backhaul (backhaul) link.

但是现在一些新型的网络场景,UE可以同时被宏小区(Macro cell)和小小区(Small cell)同时服务,即双链接场景,宏小区和小小区之间用非理想回程网络链接。对于同一个UE而言,存在两条链路为一个UE服务。But now in some new network scenarios, the UE can be served by both the macro cell (Macro cell) and the small cell (Small cell) at the same time, that is, the dual link scenario, and the non-ideal backhaul network link is used between the macro cell and the small cell. For the same UE, there are two links serving one UE.

现有的UE可以工作在上述场景中的类型有:The types of existing UEs that can work in the above scenarios include:

A,UE只有一个接收射频链(Radio Frequency,RF)和一个发送RF(即单收单发);A, UE has only one receiving radio frequency chain (Radio Frequency, RF) and one sending RF (that is, single receiving and single sending);

B,UE有一个接收RF和多个发送RF(即单收多发);B, UE has one receiving RF and multiple sending RFs (that is, single receiving and multiple sending);

C,UE有多个接收RF和一个发送RF(即多收单发);C, the UE has multiple receiving RFs and one sending RF (that is, multiple receiving and single sending);

D,UE有多个接收RF和多个发送RF(即多收多发)。D. The UE has multiple receiving RFs and multiple transmitting RFs (that is, multiple receiving and multiple sending).

在双链接场景下,一个UE被两个不同下行载波的小区服务,因为两个小区的频点不相同,所以UE需要在不同的频点间切换,该场景下需要考虑RF重调谐(RF retuning);另外,因为宏小区和小小区之间用非理想backhaul链接,数据传输存在时延,所以该方案下还需要考虑另外一个因素是混合自动重传请求的往返时间间隔定时器(Hybrid AutomaticRepeat Request Round Trip Time,HARQ RTT timer)。In a dual link scenario, a UE is served by two cells with different downlink carriers. Because the frequencies of the two cells are different, the UE needs to switch between different frequencies. In this scenario, RF retuning (RF retuning) needs to be considered. ); In addition, because the non-ideal backhaul link is used between the macro cell and the small cell, there is a delay in data transmission, so another factor that needs to be considered under this scheme is the round-trip interval timer of the Hybrid Automatic Repeat Request (Hybrid Automatic Repeat Request Round Trip Time, HARQ RTT timer).

其中,RF重调谐(retuning)是指:当UE的RF射频链由一个频点移动到另一个频点的情况;当发生RF重调谐的时候由于射频链元器件的限制,UE大约要间隔0.6ms之后才能在新频点上工作,因此当射频链发生RF重调谐的下一毫秒,UE的RF会空一个子帧。即如果下行RF发生重调谐,则UE在发生重调谐的下一毫秒不能接收;如果上行RF发生重调谐,则UE在发生重调谐的下一毫秒不能发送。Among them, RF retuning (retuning) refers to: when the RF radio frequency chain of the UE moves from one frequency point to another frequency point; when RF retuning occurs, due to the limitation of the radio frequency chain components, the UE needs to be separated by about 0.6 It can only work on the new frequency point after ms, so when the RF chain occurs in the next millisecond of RF retuning, the UE's RF will empty a subframe. That is, if the downlink RF retuning occurs, the UE cannot receive in the next millisecond after the retuning occurs; if the uplink RF retuning occurs, the UE cannot transmit in the next millisecond after the retuning occurs.

现有技术中,HARQ RTT timer被配置成8ms,即8ms的时候网络侧就要检查之前宏小区发送给UE的数据是否被成功接收,如果接收到UE侧发送的ACK消息,则确定宏小区数据发送成功;如果是NACK就是不成功;对于TDD而言,HARQ RTT timer被配置成k+4ms,k是根据TDD配比类型获得的一个可以反馈ACK/NACK的最小值。In the prior art, the HARQ RTT timer is configured to be 8ms, that is, at 8ms, the network side will check whether the data sent by the macro cell to the UE has been successfully received. If the ACK message sent by the UE side is received, the macro cell data will be determined. The transmission is successful; if it is NACK, it is unsuccessful; for TDD, the HARQ RTT timer is configured as k+4ms, and k is a minimum value that can be fed back ACK/NACK obtained according to the TDD configuration type.

由于RF retuning和HARQ RTT timer的存在,双链接场景会遇到以下这些问题:Due to the existence of RF retuning and HARQ RTT timer, the dual link scenario will encounter the following problems:

对于双链接场景下的多收单发UE而言,因为上行只有一个RF,上行反馈只能反馈到一个站点上,如果使用现有的CA技术,UE收到Small cell的通过物理下行共享信道物理(Physical Downlink Shared Channel,PDSCH)发送的下行数据之后,在Macro cell的PUCCH上发送HARQ反馈,Macro cell收到HARQ反馈后转发给small cell,以及UE在Macrocell的PUCCH上发送信道状态信息(channel state information,CSI)反馈,Macro cell收到后转发给small cell。由于双链接场景下非理想回程网络的时延典型值是20ms,导致Macro cell转发的HARQ反馈或者CSI反馈不能及时的到达小小区,不能满足HARQ时序的要求(需要4ms获取反馈)或者调度模块要求CSI反馈的时效性。For multi-receiving and single-sending UEs in the dual-link scenario, because there is only one RF in the uplink, the uplink feedback can only be fed back to one site. If the existing CA technology is used, the UE receives the small cell through the physical downlink shared channel. After the downlink data sent by (Physical Downlink Shared Channel, PDSCH), HARQ feedback is sent on the PUCCH of the Macro cell, and the Macro cell forwards the HARQ feedback to the small cell after receiving the HARQ feedback, and the UE sends channel state information (channel state information) on the PUCCH of the Macro cell information, CSI) feedback, the Macro cell forwards it to the small cell after receiving it. Since the typical delay of the non-ideal backhaul network in the dual-link scenario is 20ms, the HARQ feedback or CSI feedback forwarded by the Macro cell cannot reach the small cell in time, and cannot meet the requirements of HARQ timing (feedback needs to be 4ms) or scheduling module requirements Timeliness of CSI feedback.

针对上述问题,现有技术中提出了以下两种解决方法,具体为:In view of the above problems, the following two solutions have been proposed in the prior art, specifically:

一、UE收到Small cell通过PDSCH发送的下行数据之后,在Macro cell的PUCCH上发送HARQ反馈,Macro cell收到后转发给small cell,以及UE在Macro cell的PUCCH上发送CSI反馈,Macro cell收到后转发给small cell。1. After receiving the downlink data sent by the Small cell through the PDSCH, the UE sends HARQ feedback on the PUCCH of the Macro cell, and the Macro cell forwards it to the small cell after receiving it, and the UE sends CSI feedback on the PUCCH of the Macro cell, and the Macro cell receives After arriving, it is forwarded to the small cell.

为了实现上述数据发送方案,同时还需要修改HARQ进程的时序关系,把4ms修改成40ms等。由于增加了HARQ定时的时长,也同时需要增加HARQ时序的数量,比如到40个。HARQ时序增加导致数据包的传输时延也增加。比如重传3次,以前需要3*8=24ms,现在需要3*80=240ms。In order to realize the above data transmission solution, it is also necessary to modify the timing relationship of the HARQ process, such as changing 4 ms to 40 ms. Since the duration of the HARQ timing is increased, the number of HARQ timing sequences also needs to be increased, for example, to 40. The increase of the HARQ timing leads to an increase of the transmission delay of the data packet. For example, retransmitting 3 times previously required 3*8=24ms, but now requires 3*80=240ms.

二、如图1所示,UE的下行子帧在Macro cell上接收的时间是:子帧n+0,n+1,n+2;下行子帧在两个cell之间转换的时间是子帧n+3;下行子帧在Small cell上接收的时间是子帧n+4,n+5,n+6。2. As shown in Figure 1, the UE’s downlink subframes are received on the Macro cell at the following times: subframes n+0, n+1, n+2; the time for downlink subframes to switch between two cells is subframes Frame n+3; the downlink subframes are received on the Small cell at subframes n+4, n+5, and n+6.

UE的上行子帧在small cell上发送的时间是:子帧n+0,n+1,n+2;上行子帧在两个cell之间转换的时间是子帧n+3;上行子帧在Small cell上发送的时间是子帧n+4,n+5,n+6。The time when the UE's uplink subframe is sent on the small cell is: subframe n+0, n+1, n+2; the time for the uplink subframe to switch between two cells is subframe n+3; the uplink subframe The sending times on the Small cell are subframes n+4, n+5, and n+6.

通过上述方法实现双链接,UE的下行在Macro cell调度时,Pico cell不能调度,从而导致UE的下行吞吐量下降。Through the above method to achieve dual link, when the downlink of the UE is scheduled by the Macro cell, the Pico cell cannot be scheduled, resulting in a decrease in the downlink throughput of the UE.

上述两种现有双链接实现方式,存在的问题是:The problems existing in the above two existing double link implementation methods are:

LTE技术不能适用于在一个上行载波的场景下多基站为UE提供服务,不能有效地实现UE给多基站反馈HARQ反馈或者CSI反馈的同时,不让下行吞吐量下降,也不让时延降低超过设定阈值。LTE technology cannot be applied to the scenario where multiple base stations provide services for the UE in an uplink carrier scenario, and it cannot effectively realize that the UE feeds back HARQ feedback or CSI feedback to multiple base stations without reducing the downlink throughput or delay by more than Set the threshold.

下面结合说明书附图对本发明实施例作进一步详细描述。The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

实施例一:Embodiment one:

如图2所示,本发明实施例提供一种宏基站200,所述宏基站与小基站为一只有一个上行射频链RF的用户设备UE的服务基站,并且该宏基站和小基站工作在不同频率,则该宏基站包括:As shown in FIG. 2, an embodiment of the present invention provides a macro base station 200. The macro base station and the small base station are serving base stations for a user equipment UE with only one uplink radio frequency chain RF, and the macro base station and the small base station work in different frequency, the macro base station includes:

确定单元201,用于确定所述UE上下行资源的比例配置类型;A determining unit 201, configured to determine the proportion configuration type of the uplink and downlink resources of the UE;

当前版本8的LTE TDD系统包括7种不同的TDD上下行资源的比例配置,具体的配置情况如表1所示,表1中D表示下行子帧,S表示特殊子帧,U表示上行子帧。The current version 8 LTE TDD system includes 7 different proportion configurations of TDD uplink and downlink resources. The specific configurations are shown in Table 1. In Table 1, D represents a downlink subframe, S represents a special subframe, and U represents an uplink subframe .

表1Table 1

在实际的应用环境中UE可以选择上述7种类型中的任意一种配置进行资源分配,因为本发明实施例所提供的方案需要建立在上述帧结构的基础上,将无线帧中的上行子帧合理的分配个宏基站和小基站。所以宏基站在确定UE使用哪种类型的配置之后才能确定各上行子帧之间的间隔时间,从而能够根据各子帧之间的时间关系将不同的上行子帧分配给宏基站和小基站使用。In the actual application environment, the UE can choose any one of the above seven types of configurations for resource allocation, because the solution provided by the embodiment of the present invention needs to be based on the above frame structure, and the uplink subframe in the radio frame Reasonably allocate a macro base station and a small base station. Therefore, the macro base station can determine the interval between uplink subframes after determining which type of configuration the UE uses, so that different uplink subframes can be allocated to the macro base station and the small base station according to the time relationship between the subframes. .

时隙间隔确定单元202,用于根据确定的比例配置类型确定无线帧中任意两个相邻上行子帧集之间的特殊子帧和下行子帧的个数,根据所述特殊子帧和下行子帧的个数确定所述任意两个相邻上行子帧集之间的间隔时间;其中,所述上行子帧集由一个上行子帧或多个连续的上行子帧组成;The time slot interval determination unit 202 is configured to determine the number of special subframes and downlink subframes between any two adjacent uplink subframe sets in the radio frame according to the determined ratio configuration type, and according to the number of special subframes and downlink subframes The number of subframes determines the interval between any two adjacent uplink subframe sets; wherein, the uplink subframe set consists of one uplink subframe or multiple consecutive uplink subframes;

如表1所述提供的比例配置中,如果UE选择比例配置类型0,则在本发明实施例的所述时隙间隔确定单元将子帧2、3和4作为一个上行子帧集,子帧7、8和9作为另一个子帧集,宏基站为了指示自身以及小基站在不同的子帧集中传输数据,则需要确定两个子帧集之间的时间间隔,从而能够根据这个时间间隔确定接收或者是发送数据的子帧位置。所以在比例配置类型0中,子帧集就包括由子帧2、3和4组成的第一个上行子帧集;由子帧7、8和9组成的第二个上行子帧集,因为宏基站和小基站确定各自要使用的子帧集后,则使用两个上行子帧集之间的特殊子帧和/或下行子帧(即所述间隔时间)进行宏基站和小基站之间的切换。In the proportion configuration provided as described in Table 1, if the UE selects the proportion configuration type 0, the time slot interval determination unit in the embodiment of the present invention uses subframes 2, 3 and 4 as an uplink subframe set, and the subframe 7, 8, and 9 are another subframe set. In order to instruct itself and the small base station to transmit data in different subframe sets, the macro base station needs to determine the time interval between the two subframe sets, so that the reception can be determined according to this time interval. Or the subframe position where the data is sent. Therefore, in proportion configuration type 0, the subframe set includes the first uplink subframe set composed of subframes 2, 3 and 4; the second uplink subframe set composed of subframes 7, 8 and 9, because the macro base station After the small base station and the small base station determine the subframe sets to be used respectively, use the special subframe and/or downlink subframe (that is, the interval time) between the two uplink subframe sets to perform handover between the macro base station and the small base station .

上述是以类型0为例进行的说明,其他类型和类型0的实现方式相同;例如:类型3中,上行子帧集是子帧2、3和4组成的。如果宏基站使用当前无线帧的子帧2、3和4组成的上行子帧集,则小基站对应的使用下一个无线帧的子帧2、3和4组成的上行子帧集。The above description is based on type 0 as an example, other types are implemented in the same way as type 0; for example: in type 3, the uplink subframe set is composed of subframes 2, 3 and 4. If the macro base station uses the uplink subframe set composed of subframes 2, 3 and 4 of the current radio frame, the small base station correspondingly uses the uplink subframe set composed of subframes 2, 3 and 4 of the next radio frame.

反馈时隙协调单元203,用于根据所述间隔时间从无线帧中的确定上行子帧集作为宏基站对应的第一下行反馈时隙和所述小基站对应的第二下行反馈时隙,其中,所述第一下行反馈时隙与所述第二下行反馈时隙之间间隔一个间隔时间;The feedback time slot coordinating unit 203 is configured to determine the uplink subframe set in the radio frame as the first downlink feedback time slot corresponding to the macro base station and the second downlink feedback time slot corresponding to the small base station according to the interval time, Wherein, there is an interval between the first downlink feedback time slot and the second downlink feedback time slot;

在本发明实施例中,因为UE可以接收到宏基站和小基站的数据,所以在确定无线帧中上行子帧集的位置后,将一个上行射频链对应的无线帧上行资源协调分配给宏基站和小基站。In the embodiment of the present invention, because the UE can receive the data of the macro base station and the small base station, after determining the position of the uplink subframe set in the radio frame, the uplink resources of the radio frame corresponding to an uplink radio frequency chain are coordinated and allocated to the macro base station and small base stations.

宏基站和小基站确定自身对应的上行子帧集之后,就可以确定不同的上行子帧集作为宏基站对应的第一下行反馈时隙和所述小基站对应的第二下行反馈时隙。After the macro base station and the small base station determine their corresponding uplink subframe sets, they can determine different uplink subframe sets as the first downlink feedback time slot corresponding to the macro base station and the second downlink feedback time slot corresponding to the small base station.

第一指令处理单元204,用于根据第一下行反馈时隙和第二下行反馈时隙生成第一控制指令,并将该第一控制指令发送到所述小基站,其中所述第一控制指令用于小基站和宏基站在不同的上行子帧集接收所述UE的上行反馈。The first instruction processing unit 204 is configured to generate a first control instruction according to the first downlink feedback time slot and the second downlink feedback time slot, and send the first control instruction to the small base station, wherein the first control The instruction is used for the small base station and the macro base station to receive the uplink feedback of the UE in different sets of uplink subframes.

在本发明实施例中,因为需要宏基站和小基站协调使用UE唯一的上行射频链,所以宏基站和小基站需要协调好自身所使用的上行,所以通过上述方案宏基站确定好可使用的上行子帧的位置之后,则需要和小基站确定各自都使用哪一部分上行子帧。其中宏基站和小基站确定各自使用的上行子帧的具体实现方式可以是:In the embodiment of the present invention, because the macro base station and the small base station need to coordinate the use of the UE's unique uplink radio frequency chain, the macro base station and the small base station need to coordinate the uplink used by themselves, so the macro base station determines the available uplink through the above scheme After the location of the subframe, it needs to determine with the small base station which part of the uplink subframe each uses. The specific implementation manner in which the macro base station and the small base station determine the uplink subframes used by them may be:

本发明实施例中,因为UE只有一个上行射频链,但是对应了两个服务基站,所以需要两个服务基站协调使用这一个上行射频链。在两个基站协调使用这一个上行射频链的具体实现方式可以是:In the embodiment of the present invention, since the UE has only one uplink radio frequency chain, but corresponds to two serving base stations, the two serving base stations need to coordinate the use of the one uplink radio frequency chain. A specific implementation manner of coordinating the use of this uplink radio frequency chain between two base stations may be:

A,网络侧的Macro eNB和Small eNB协商UE的HARQ RTT timer;具体实现可以是:A. The Macro eNB on the network side and the Small eNB negotiate the HARQ RTT timer of the UE; the specific implementation can be:

Macro eNB向Small eNB发送协商请求,该协商请求用于指示需要与Small eNB共用所述UE的一个上行射频链;The Macro eNB sends a negotiation request to the Small eNB, where the negotiation request is used to indicate that an uplink radio frequency chain of the UE needs to be shared with the Small eNB;

接收Small eNB反馈的针对所述协商请求的响应消息(response),根据所述响应消息确定Small eNB是否同意共用所述上行射频链。receiving a response message (response) fed back by the Small eNB for the negotiation request, and determining whether the Small eNB agrees to share the uplink radio frequency chain according to the response message.

B,Macro eNB统一计算Macro eNB和Small eNB怎么使用UE一个上行射频链路,并将计算结果通知Small eNB;Small eNB接收到通知后就直接根据Macro eNB的指示接收UE的下行反馈。B. Macro eNB uniformly calculates how Macro eNB and Small eNB use an uplink radio frequency link of UE, and notifies Small eNB of the calculation result; after receiving the notification, Small eNB receives UE's downlink feedback directly according to Macro eNB's instructions.

在本发明实施例中,小基站和宏基站只要协调确定怎么共用一个上行射频链,并相互通知各自使用的子帧,则可实现本发明所要求的两个服务小区为只有一个上行射频链的UE服务的技术效果,所以在本发明实施例中,所述宏基站在确定好宏基站和小基站对所述一个上行射频链的使用情况后,宏基站与小基站协调所述上行射频链怎么使用的方式包括多种,以下提供两种最常用的方式:In the embodiment of the present invention, as long as the small base station and the macro base station coordinate to determine how to share an uplink radio frequency chain, and notify each other of the subframes used by each other, the two serving cells required by the present invention can be realized as having only one uplink radio frequency chain. Therefore, in the embodiment of the present invention, after the macro base station determines the use of the one uplink radio frequency chain by the macro base station and the small base station, the macro base station and the small base station coordinate how the uplink radio frequency chain There are many ways to use it, the two most commonly used ways are provided below:

方式一、因为宏基站和小基站都有自己的HARQ RTT timer,所以宏基站在确定自己的HARQ RTT timer之后,可以将自身的HARQ RTT timer发送给小基站,小基站则可根据接收到的宏基站的HARQ RTT timer确定自身的HARQ RTT timer。从而使得两个两个基站能够协调共用UE的一个上行射频链。所以在该实施例中:Method 1: Because both the macro base station and the small base station have their own HARQ RTT timers, after the macro base station determines its own HARQ RTT timer, it can send its own HARQ RTT timer to the small base station, and the small base station can The HARQ RTT timer of the station determines its own HARQ RTT timer. Thus, two base stations can coordinate and share one uplink radio frequency chain of the UE. So in this example:

所述第一指令处理单元204发送的所述第一控制指令中包括所述宏基站的HARQRTT timer,使得所述小基站接收到所述宏基站的HARQ RTT timer后设置自身的HARQ RTTtimer。The first control instruction sent by the first instruction processing unit 204 includes the HARQ RTT timer of the macro base station, so that the small base station sets its own HARQ RTT timer after receiving the HARQ RTT timer of the macro base station.

方式二、因为宏基站会确定自身以及小基站使用所述UE上行射频链的子帧,所以宏基站在确定好怎样使用所述UE上行射频链的具体方式后,可以直接将所述小基站使用所述上行射频链的时刻值直接发送给小基站,使得小基站能够根据所述时刻值设置自身的HARQ RTT timer。Method 2: Because the macro base station will determine that itself and the small base station use the subframe of the UE uplink radio frequency chain, the macro base station can directly use the small base station to use the UE uplink radio frequency chain The time value of the uplink radio frequency chain is directly sent to the small base station, so that the small base station can set its own HARQ RTT timer according to the time value.

另外,因为所述宏基站和小基站可以是:时分双工(Time Division Duplexing,TDD)方式工作也可以是频分双工(Frequency Division Duplexing,FDD)方式工作,当基站以为FDD方式工作时,因为宏基站和小基站所使用的频点不相同,所以UE为了向不同的基站交互需要在不同的频点间切换,所以当所述宏基站和小基站分别以FDD工作方式工作时,若UE发送针对两个基站的上行反馈,则需要RF射频链由一个频点移动到另一个频点(即RFretuning),因为发生RF retuning的时候由于射频链元器件的限制,不能做到立即在新频点上工作,中间需要一定的切换时间。所以在这种情况下,宏基站和小基站计算UE的上行反馈时间时,需要将所述RF retuning的时间去除。所以当所述宏基站和小基站分别以FDD工作方式工作,所述反馈时隙协调单元203确定所述间隔时间为UE RF retuning的时间。In addition, because the macro base station and the small base station can work in a time division duplex (Time Division Duplexing, TDD) mode or in a frequency division duplex (Frequency Division Duplexing, FDD) mode, when the base station works in an FDD mode, Because the frequency points used by the macro base station and the small base station are different, the UE needs to switch between different frequency points in order to interact with different base stations. Therefore, when the macro base station and the small base station work in FDD mode, if the UE Sending uplink feedback for two base stations requires the RF chain to move from one frequency point to another frequency point (that is, RFretuning), because when RF retuning occurs due to the limitations of the RF chain components, it cannot be immediately retuned on the new frequency point. Click to work, and it takes a certain switching time in the middle. Therefore, in this case, when the macro base station and the small base station calculate the uplink feedback time of the UE, the RF retuning time needs to be removed. Therefore, when the macro base station and the small base station respectively work in the FDD mode, the feedback slot coordinating unit 203 determines that the interval time is the time of UE RF retuning.

在现有技术中,还有一些UE不仅上行射频链只有一个,下行射频连也只有一个,对于一个传统的非CA的UE只能同一个站点链接,两个RF分别工作在上行和下行,在FDD网络下,因为上下行是不同的频点,因此需要上行RF和下行RF同时工作,然而在TDD网络下,当上行RF工作的时候,下行RF是空闲的,当下行RF工作的时候,上行RF是空闲的。为了提高用户设备RF的利用率,在TDD网络下,可以将空闲的RF启用,协调宏基站和小基站使用原来空闲的RF发送数据。为了实现上述目的,宏基站和小基站还需要进一步的确定多个协调操作的参数。所以该基站还包括:In the existing technology, some UEs not only have only one uplink radio frequency chain, but also only one downlink radio frequency chain. For a traditional non-CA UE, it can only be connected to the same site. The two RFs work in the uplink and downlink respectively. Under the FDD network, because the uplink and downlink are different frequency points, the uplink RF and the downlink RF need to work at the same time. However, under the TDD network, when the uplink RF is working, the downlink RF is idle, and when the downlink RF is working, the uplink RF RF is idle. In order to improve the utilization rate of the RF of the user equipment, in the TDD network, the idle RF can be enabled, and the macro base station and the small base station can be coordinated to use the original idle RF to send data. In order to achieve the above purpose, the macro base station and the small base station need to further determine a plurality of coordinated operation parameters. So the base station also includes:

子帧个数确定单元205,用于根据所述比例配置类型确定所述UE的下行子帧集的位置和所述下行子帧集中的子帧个数;A subframe number determining unit 205, configured to determine the position of the downlink subframe set of the UE and the number of subframes in the downlink subframe set according to the proportional configuration type;

第二指令处理单元206,用于当确定每个上行子帧集包括的子帧个数不小于2,根据所述下行子帧集位置和所述下行子帧集中的子帧个数生成第二控制指令,并将所述第二控制指令发送到所述UE和所述小基站,所述第二控制指令用于指示所述小基站在下行子帧发送下行数据;并指示所述UE使用上行RF在所述下行子帧的位置接收所述小基站发送的下行数据,并在所述上行子帧集中的最后一个子帧和特殊子帧切换回上行RF。The second instruction processing unit 206 is configured to generate a second instruction according to the position of the downlink subframe set and the number of subframes in the downlink subframe set when it is determined that the number of subframes included in each uplink subframe set is not less than 2. control instruction, and send the second control instruction to the UE and the small base station, the second control instruction is used to instruct the small base station to send downlink data in the downlink subframe; and instruct the UE to use the uplink The RF receives the downlink data sent by the small base station at the position of the downlink subframe, and switches back to the uplink RF in the last subframe and special subframe in the set of uplink subframes.

在本发明实施例中,对于一个传统的非CA的UE只能同一个站点链接,两个RF分别工作在上行和下行,在FDD网络下,因为上下行是不同的频点,因此需要上行RF和下行RF同时工作,然而在TDD网络下,当上行RF工作的时候,下行RF是空闲的,当下行RF工作的时候,上行RF是空闲的。所以在本实施例中,为了将空闲的RF利用起来,所以可以将上行RF切换成接收下行数据的下行RF,从而就可以使用两个下行RF分别对应接收宏基站和小基站的发送的数据。In the embodiment of the present invention, a traditional non-CA UE can only be connected to one site, and the two RFs work on the uplink and downlink respectively. Under the FDD network, because the uplink and downlink are different frequency points, the uplink RF is required. It works at the same time as the downlink RF, but under the TDD network, when the uplink RF is working, the downlink RF is idle, and when the downlink RF is working, the uplink RF is idle. Therefore, in this embodiment, in order to utilize the idle RF, the uplink RF can be switched to the downlink RF for receiving downlink data, so that two downlink RFs can be used to receive the data sent by the macro base station and the small base station respectively.

但是因为RF在上行和下行之间切换时,不能做到立即在新频点上工作,中间需要一定的切换时间。所以为了保证RF的上下行切换以及上行数据的正常传输,则需要确定上行子帧集包括的子帧个数不小于2。因为所述上行子帧集需要一部分资源用于上行数据的传输,另外一部分资源用于实现所述RF的上下行切换所需的切换时间。However, when RF switches between uplink and downlink, it cannot work on the new frequency point immediately, and a certain switching time is required in the middle. Therefore, in order to ensure RF uplink and downlink switching and normal transmission of uplink data, it is necessary to determine that the number of subframes included in the uplink subframe set is not less than 2. Because the set of uplink subframes requires a part of resources for transmission of uplink data, and another part of resources is used for switching time required for uplink and downlink switching of the RF.

在双链接网络中,由于一个UE可以有两个站同时为其服务,对于只有一个上行和一个下行RF的UE充分利用空闲的RF,当双链接网络的Macro cell和Small cell都是TDD模式,UE可以获得双链接网络在吞吐量上的增益。In a dual-link network, since a UE can have two stations serving it at the same time, for a UE with only one uplink and one downlink RF, make full use of the idle RF. When the Macro cell and Small cell of the dual-link network are both in TDD mode, The UE can obtain the throughput gain of the dual link network.

在本发明实施例中,所述宏基站和小基站之间发送控制指令的方式可以是多种,可选方式可以是:In the embodiment of the present invention, there may be multiple ways of sending control instructions between the macro base station and the small base station, and the optional ways may be:

所述第二指令处理单元206还用于使用广播消息、无线资源控制RRC信令、媒体接入控制层控制单元MACCE或者物理层命令中的一种或者多种方式的组合,将所述第二控制指令发送给所述UE和所述小基站。The second instruction processing unit 206 is further configured to send the second The control instruction is sent to the UE and the small base station.

本发明实施例所提供的方案中,当工作在不同频率的宏基站和小基站同时为UE提供服务时,本发明实施例所提供的基站,能够确定一个或者是连续两个无线帧中的上行子帧集,然后将多个上行子帧集合理的分配给宏基站或者是小基站,从而使得宏基站和小基站能够在不冲突的前提下,给UE提供服务。所以本发明所提供的方案可以使只设置有一个上行射频链的UE(包括单发送多接收以及单发单收的UE)可以享受到双链接网络的增益。In the solution provided by the embodiment of the present invention, when the macro base station and the small base station working on different frequencies provide services for the UE at the same time, the base station provided by the embodiment of the present invention can determine the uplink frequency in one or two consecutive radio frames. Subframe sets, and then reasonably allocate multiple uplink subframe sets to the macro base station or the small base station, so that the macro base station and the small base station can provide services to the UE without conflict. Therefore, the solution provided by the present invention can enable UEs with only one uplink radio frequency chain (including UEs with single transmission and multiple reception and single transmission and single reception) to enjoy the gain of the dual-link network.

上述方案中虽然是以宏基站为主导设备对本发明的方案进行的实施描述,但是在具体的实现过程中,也可以是UE或者是小基站执行实施例所提供模块所实现的方案。In the above solution, although the macro base station is used as the leading device to describe the implementation of the solution of the present invention, in the specific implementation process, the UE or the small base station may also implement the solution implemented by the modules provided in the embodiment.

实施例二:Embodiment two:

在本发明实施例所提供的方案中,宏基站根据UE的上下行资源比列配置类型确定好自身和小基站各自使用的上行子帧集之后,则需要将最后的协调结果发送到用户设备UE,使得用户设备根据宏基站确定的协调结果调节上行子帧所对应的基站,所以基于上述方案中提供的宏基站,在本发明实施例还提供一种用户设备,用户设备包括(如图3所示):In the solution provided by the embodiment of the present invention, after the macro base station determines the uplink subframe sets used by itself and the small base station according to the uplink and downlink resource ratio configuration type of the UE, it needs to send the final coordination result to the user equipment UE so that the user equipment adjusts the base station corresponding to the uplink subframe according to the coordination result determined by the macro base station, so based on the macro base station provided in the above solution, an embodiment of the present invention also provides a user equipment, the user equipment includes (as shown in FIG. 3 Show):

接收模块301,接收宏基站发送的所述第一控制指令,并接收宏基站和小基站发送的下行数据;The receiving module 301 is configured to receive the first control instruction sent by the macro base station, and receive downlink data sent by the macro base station and the small base station;

反馈时隙确定单元302,用于根据所述第一控制指令确定对应所述宏基站和所述小基站的第一下行反馈时隙和第二下行反馈时隙;A feedback time slot determining unit 302, configured to determine a first downlink feedback time slot and a second downlink feedback time slot corresponding to the macro base station and the small base station according to the first control instruction;

因为宏基站在确定自身和小基站所对应的上行子帧集之后,用户设备则需要根据宏基站协调好的结果,将不同的上行子帧作为针对不同基站的下行反馈时隙。Because after the macro base station determines the set of uplink subframes corresponding to itself and the small base station, the user equipment needs to use different uplink subframes as downlink feedback time slots for different base stations according to the coordination result of the macro base station.

发送模块303,用于利用所述第一下行反馈时隙和第二下行反馈时隙将所述下行数据的反馈信息分别反馈到所述宏基站和所述小基站。The sending module 303 is configured to use the first downlink feedback time slot and the second downlink feedback time slot to respectively feed back the feedback information of the downlink data to the macro base station and the small base station.

因为用户设备接收了两个基站发送的下行数据,所以用户设备需要在不同的上行子帧集中反馈所述下行数据所对应的反馈信息。Because the user equipment has received the downlink data sent by the two base stations, the user equipment needs to feed back the feedback information corresponding to the downlink data in different uplink subframe sets.

例如:用户设备的上下行资源比例配置为类型0,则用户设备根据第一控制指令可以将第一个上行子帧集(由子帧2、3和4组成)作为针对所述宏基站的第一下行反馈时隙;将第二个上行子帧集(由子帧7、8和9组成)作为针对所述小基站的第二下行反馈时隙。For example, if the uplink and downlink resource ratio of the user equipment is configured as type 0, the user equipment can use the first uplink subframe set (composed of subframes 2, 3 and 4) as the first set of uplink subframes for the macro base station according to the first control instruction. Downlink feedback time slot: the second uplink subframe set (composed of subframes 7, 8 and 9) is used as the second downlink feedback time slot for the small base station.

另外,因为所述宏基站和小基站可以是TDD方式工作也可以是FDD方式工作,当基站以为FDD方式工作时,因为宏基站和小基站所使用的频点不相同,所以UE为了向不同的基站交互需要在不同的频点间切换,所以当所述宏基站和小基站分别以FDD工作方式工作时,若UE发送针对两个基站的上行反馈,则需要RF射频链由一个频点移动到另一个频点(即RFretuning),因为发生RF retuning的时候由于射频链元器件的限制,不能做到立即在新频点上工作,中间会出现一定的切换时间。所以当所述宏基站和小基站分别都以FDD工作方式工作时,则所述发送模块303还用在第一下行反馈时隙和第二下行反馈时隙之间的间隔时间进行RF重调谐RF retuning。In addition, because the macro base station and the small base station can work in TDD mode or FDD mode, when the base station works in FDD mode, because the frequency points used by the macro base station and the small base station are not the same, so in order for the UE to communicate with different Base station interaction needs to switch between different frequency points, so when the macro base station and the small base station work in FDD mode, if the UE sends uplink feedback for the two base stations, the RF radio frequency chain needs to be moved from one frequency point to Another frequency point (ie, RFretuning), because when RF retuning occurs, due to the limitation of RF chain components, it cannot immediately work on the new frequency point, and there will be a certain switching time in the middle. Therefore, when the macro base station and the small base station are both working in the FDD mode, the sending module 303 also uses the interval between the first downlink feedback time slot and the second downlink feedback time slot to perform RF retuning RF retuning.

对于一个传统的非CA的UE只能同一个站点链接,两个RF分别工作在上行和下行,在FDD网络下,因为上下行是不同的频点,因此需要上行RF和下行RF同时工作,然而在TDD网络下,当上行RF工作的时候,下行RF是空闲的,当下行RF工作的时候,上行RF是空闲的。为了提高用户设备RF的利用率,在TDD网络下,可以将空闲的RF启用,在空闲RF启用的情况下,用户设备则可以看做是具有两个下行RF的设备,所以就可以将两个RF分别接收宏基站和小基站发送的下行数据。所以在TDD网络下,当所述用户设备只有一个下行射频链,则:For a traditional non-CA UE, it can only be connected to the same site, and the two RFs work on the uplink and downlink respectively. Under the FDD network, because the uplink and downlink are different frequency points, the uplink RF and the downlink RF need to work at the same time. However, In a TDD network, when the uplink RF is working, the downlink RF is idle, and when the downlink RF is working, the uplink RF is idle. In order to improve the utilization rate of the RF of the user equipment, in the TDD network, the idle RF can be enabled. When the idle RF is enabled, the user equipment can be regarded as a device with two downlink RFs, so the two The RF respectively receives the downlink data sent by the macro base station and the small base station. Therefore, under the TDD network, when the user equipment has only one downlink radio frequency chain, then:

所述接收模块301还用于在接收到所述第二控制指令之后,根据所述第二控制指令使用上行RF在下行子帧的位置接收所述小基站发送的下行数据,并在所述上行子帧集的最后一个子帧或特殊子帧切换回上行RF。The receiving module 301 is further configured to, after receiving the second control instruction, use the uplink RF to receive the downlink data sent by the small base station at the position of the downlink subframe according to the second control instruction, and The last subframe or special subframe of the subframe set switches back to the uplink RF.

本发明实施例所提供的方案中,当工作在不同频率的宏基站和小基站同时为UE提供服务时,用户设备UE为了能够合理的利用自身的射频链资源,将唯一的上行射频链在不同的基站之间切换,从而能够将宏基站和小基站发送的数据的反馈信息对应的反馈给宏基站和小基站。In the solution provided by the embodiment of the present invention, when the macro base station and the small base station operating at different frequencies provide services for the UE at the same time, the user equipment UE uses its own radio frequency chain resources reasonably, and uses the only uplink radio frequency chain in different handover between the base stations, so that the feedback information of the data sent by the macro base station and the small base station can be fed back to the macro base station and the small base station correspondingly.

另外,在TDD网络下,当用户设备只设置有一个上行射频链和一个下行射频链时,为了提高UE的RF利用率,则可以将原本用于上行的RF切换到下行,从而将原来用于分别接收上行和下行的两个RF同时用于接收宏基站和小基站的下行数据,从而达到双链接网络的增益。In addition, in a TDD network, when the user equipment is only provided with one uplink radio frequency chain and one downlink radio frequency chain, in order to improve the RF utilization rate of the UE, the RF originally used for uplink can be switched to downlink, so that the RF originally used for uplink can be switched to downlink. The two RFs that respectively receive the uplink and downlink are used to receive the downlink data of the macro base station and the small base station at the same time, so as to achieve the gain of the dual-link network.

实施例三:Embodiment three:

如图4所示,基于上述装置本发明实施例还提供一种单射频UE射频资源分配方法,当宏基站与小基站为一只有一个上行射频链RF的用户设备UE的服务基站,并且该宏基站和小基站工作在不同频率,该方法包括:As shown in FIG. 4 , based on the above-mentioned device, an embodiment of the present invention also provides a method for allocating radio frequency resources of a single-radio UE. The base station and the small base station work at different frequencies, the method includes:

步骤401,所述宏基站确定所述UE上下行资源的比例配置类型;Step 401, the macro base station determines the proportion configuration type of the uplink and downlink resources of the UE;

步骤402,所述宏基站根据确定的比例配置类型确定无线帧中任意两个相邻上行子帧集之间的特殊子帧和下行子帧的个数,根据所述特殊子帧和下行子帧的个数确定所述任意两个相邻上行子帧集之间的间隔时间;其中,所述上行子帧集由一个上行子帧或多个连续的上行子帧组成;Step 402, the macro base station determines the number of special subframes and downlink subframes between any two adjacent uplink subframe sets in the radio frame according to the determined ratio configuration type, and according to the number of special subframes and downlink subframes The number determines the interval time between any two adjacent uplink subframe sets; wherein, the uplink subframe set consists of one uplink subframe or a plurality of consecutive uplink subframes;

步骤403,所述宏基站根据所述间隔时间从无线帧中的确定上行子帧集作为宏基站对应的第一下行反馈时隙和所述小基站对应的第二下行反馈时隙,其中,所述第一下行反馈时隙与所述第二下行反馈时隙之间间隔一个间隔时间;Step 403, the macro base station determines the uplink subframe set from the radio frame according to the interval time as the first downlink feedback time slot corresponding to the macro base station and the second downlink feedback time slot corresponding to the small base station, wherein, There is an interval between the first downlink feedback time slot and the second downlink feedback time slot;

步骤404,所述宏基站根据第一下行反馈时隙和第二下行反馈时隙生成第一控制指令,并将该第一控制指令发送到所述小基站,其中所述第一控制指令用于小基站和宏基站在不同的上行子帧集接收所述UE的上行反馈。Step 404, the macro base station generates a first control instruction according to the first downlink feedback time slot and the second downlink feedback time slot, and sends the first control instruction to the small base station, wherein the first control instruction uses Because the small base station and the macro base station receive the uplink feedback of the UE in different uplink subframe sets.

另外,因为所述宏基站和小基站可以是TDD方式工作也可以是FDD方式工作,当基站为FDD方式工作时,因为宏基站和小基站所使用的频点不相同,所以UE为了向不同的基站交互需要在不同的频点间切换,所以宏基站与小基站所占用的UE上行射频链中的子帧集之间则间隔一个RF retuning所花费的时间。所以该方法还包括:In addition, because the macro base station and the small base station can work in TDD mode or FDD mode, when the base station works in FDD mode, because the frequency points used by the macro base station and the small base station are different, so in order for the UE to communicate with different Base station interaction needs to switch between different frequency points, so there is an interval of one RF retuning time between the subframe sets in the UE uplink radio frequency chain occupied by the macro base station and the small base station. So the method also includes:

当所述宏基站和小基站分别以FDD工作方式工作,所述宏基站确定所述间隔时间为RF重调谐RF retuning的时间。When the macro base station and the small base station respectively work in the FDD working mode, the macro base station determines that the interval time is a time for RF retuning RF retuning.

在现有技术中,还有一些UE不仅上行射频链只有一个,下行射频连也只有一个,对于一个传统的非CA的UE只能同一个站点链接,两个RF分别工作在上行和下行,在FDD网络下,因为上下行是不同的频点,因此需要上行RF和下行RF同时工作,然而在TDD网络下,当上行RF工作的时候,下行RF是空闲的,当下行RF工作的时候,上行RF是空闲的。为了提高用户设备RF的利用率,在TDD网络下,可以将空闲的RF启用,协调宏基站和小基站使用原来空闲的RF发送数据。为了实现上述目的,则该方法包括:In the existing technology, some UEs not only have only one uplink radio frequency chain, but also only one downlink radio frequency chain. For a traditional non-CA UE, it can only be connected to the same site. The two RFs work in the uplink and downlink respectively. Under the FDD network, because the uplink and downlink are different frequency points, the uplink RF and the downlink RF need to work at the same time. However, under the TDD network, when the uplink RF is working, the downlink RF is idle, and when the downlink RF is working, the uplink RF RF is idle. In order to improve the utilization rate of the RF of the user equipment, in the TDD network, the idle RF can be enabled, and the macro base station and the small base station can be coordinated to use the original idle RF to send data. In order to achieve the above purpose, the method includes:

所述宏基站根据所述比例配置类型确定所述UE的下行子帧集的位置和所述下行子帧集中的子帧个数;The macro base station determines the position of the downlink subframe set of the UE and the number of subframes in the downlink subframe set according to the proportional configuration type;

所述宏基站当确定每个上行子帧集包括的子帧个数大于2,则根据所述下行子帧集位置和所述下行子帧集中的子帧个数生成第二控制指令,并将所述第二控制指令发送到所述UE和所述小基站,所述第二控制指令用于指示所述小基站在所述上行子帧集发送下行数据;并指示所述UE使用上行RF在所述上行子帧集的位置接收所述小基站发送的下行数据,并在所述上行子帧集中的最后一个子帧切换回上行RF。When the macro base station determines that the number of subframes included in each uplink subframe set is greater than 2, it generates a second control instruction according to the position of the downlink subframe set and the number of subframes in the downlink subframe set, and sends The second control instruction is sent to the UE and the small base station, the second control instruction is used to instruct the small base station to send downlink data in the uplink subframe set; and instruct the UE to use the uplink RF in the The position of the uplink subframe set receives the downlink data sent by the small base station, and switches back to uplink RF in the last subframe of the uplink subframe set.

在本发明实施例中,所述宏基站和小基站之间发送控制指令的方式可以是多种,可选方式可以是:In the embodiment of the present invention, there may be multiple ways of sending control instructions between the macro base station and the small base station, and the optional ways may be:

所述宏基站使用广播消息、RRC信令、MACCE或者物理层命令中的任一方式或者多种方式的组合,将所述控制指令(该控制指令包括第一控制指令和第二控制指令)发送给所述UE和所述小基站。The macro base station sends the control instruction (the control instruction includes a first control instruction and a second control instruction) using any method or a combination of broadcast messages, RRC signaling, MACCE or physical layer commands to the UE and the small base station.

在本发明实施例中,小基站和宏基站只要协调确定怎么共用一个上行射频链,并相互通知各自使用的子帧,则可实现本发明所要求的两个服务小区为只有一个上行射频链的UE服务的技术效果,所以在本发明实施例中,所述宏基站在确定好宏基站和小基站对所述一个上行射频链的使用情况后,宏基站与小基站协调所述上行射频链怎么使用的方式包括多种,具体方式可以是:In the embodiment of the present invention, as long as the small base station and the macro base station coordinate to determine how to share an uplink radio frequency chain, and notify each other of the subframes used by each other, the two serving cells required by the present invention can be realized as having only one uplink radio frequency chain. Therefore, in the embodiment of the present invention, after the macro base station determines the use of the one uplink radio frequency chain by the macro base station and the small base station, the macro base station and the small base station coordinate how the uplink radio frequency chain There are many ways to use, and the specific ways can be:

所述第一控制指令中包括所述宏基站的HARQ RTT timer,使得所述小基站接收到所述宏基站的HARQ RTT timer后设置自身的HARQ RTT timer。The first control instruction includes the HARQ RTT timer of the macro base station, so that the small base station sets its own HARQ RTT timer after receiving the HARQ RTT timer of the macro base station.

实施例四:Embodiment four:

在本发明实施例所提供的方案中,宏基站根据UE的上下行资源比列配置类型确定好自身和小基站各自使用的上行子帧集之后,则需要将最后的协调结果发送到用户设备UE,使得用户设备UE根据宏基站确定的协调结果调节上行子帧所对应的基站,所以基于实施例三中提供的方法,在本发明实施例还提供一种单射频使用方法,该方法包括(流程如图5所示):In the solution provided by the embodiment of the present invention, after the macro base station determines the uplink subframe sets used by itself and the small base station according to the uplink and downlink resource ratio configuration type of the UE, it needs to send the final coordination result to the user equipment UE so that the user equipment UE adjusts the base station corresponding to the uplink subframe according to the coordination result determined by the macro base station, so based on the method provided in the third embodiment, a method for using a single radio frequency is also provided in the embodiment of the present invention, the method includes (flow process As shown in Figure 5):

步骤501,所述用户设备接收宏基站发送的第一控制指令,并接收宏基站和小基站发送的下行数据;Step 501, the user equipment receives a first control instruction sent by the macro base station, and receives downlink data sent by the macro base station and the small base station;

步骤502,所述用户设备根据所述第一控制指令确定对应所述宏基站和所述小基站的第一下行反馈时隙和第二下行反馈时隙;Step 502, the user equipment determines a first downlink feedback time slot and a second downlink feedback time slot corresponding to the macro base station and the small base station according to the first control instruction;

步骤503,所述用户设备利用所述第一下行反馈时隙和第二下行反馈时隙将所述下行数据的反馈信息分别反馈到所述宏基站和所述小基站。Step 503, the user equipment uses the first downlink feedback time slot and the second downlink feedback time slot to respectively feed back the feedback information of the downlink data to the macro base station and the small base station.

因为用户设备接收了两个基站发送的下行数据,所以用户设备需要在不同的上行子帧集中反馈所述下行数据所对应的反馈信息。Because the user equipment has received the downlink data sent by the two base stations, the user equipment needs to feed back the feedback information corresponding to the downlink data in different uplink subframe sets.

例如:用户设备的上下行资源比例配置为类型0,则用户设备根据第一控制指令可以将第一个上行子帧集(由子帧2、3和4组成)作为针对所述宏基站的第一下行反馈时隙;将第二个上行子帧集(由子帧7、8和9组成)作为针对所述小基站的第二下行反馈时隙。For example, if the uplink and downlink resource ratio of the user equipment is configured as type 0, the user equipment can use the first uplink subframe set (composed of subframes 2, 3 and 4) as the first set of uplink subframes for the macro base station according to the first control instruction. Downlink feedback time slot: the second uplink subframe set (composed of subframes 7, 8 and 9) is used as the second downlink feedback time slot for the small base station.

另外,因为所述宏基站和小基站可以是TDD方式工作也可以是FDD方式工作,当基站以为FDD方式工作时,因为宏基站和小基站所使用的频点不相同,所以UE为了向不同的基站交互需要在不同的频点间切换,所以当所述宏基站和小基站分别以FDD工作方式工作时,若UE发送针对两个基站的上行反馈,则需要RF射频链由一个频点移动到另一个频点(即RFretuning),因为发生RF retuning的时候由于射频链元器件的限制,不能做到立即在新频点上工作,中间会出现一定的切换时间。所以当所述宏基站和小基站分别都以FDD工作方式工作时,则所述当所述宏基站和小基站分别以FDD工作方式工作,该方法还包括:In addition, because the macro base station and the small base station can work in TDD mode or FDD mode, when the base station works in FDD mode, because the frequency points used by the macro base station and the small base station are not the same, so in order for the UE to communicate with different Base station interaction needs to switch between different frequency points, so when the macro base station and the small base station work in FDD mode, if the UE sends uplink feedback for the two base stations, the RF radio frequency chain needs to be moved from one frequency point to Another frequency point (ie, RFretuning), because when RF retuning occurs, due to the limitation of RF chain components, it cannot immediately work on the new frequency point, and there will be a certain switching time in the middle. Therefore, when the macro base station and the small base station respectively work in the FDD working mode, the method further includes:

所述用户设备在第一下行反馈时隙和第二下行反馈时隙之间的间隔时间进行RF重调谐RF retuning。The user equipment performs RF retuning RF retuning at an interval between the first downlink feedback time slot and the second downlink feedback time slot.

对于一个传统的非CA的UE只能同一个站点链接,两个RF分别工作在上行和下行,在FDD网络下,因为上下行是不同的频点,因此需要上行RF和下行RF同时工作,然而在TDD网络下,当上行RF工作的时候,下行RF是空闲的,当下行RF工作的时候,上行RF是空闲的。为了提高用户设备RF的利用率,在TDD网络下,可以将空闲的RF启用,在空闲RF启用的情况下,用户设备则可以看做是具有两个下行RF的设备,所以就可以将两个RF分别接收宏基站和小基站发送的下行数据。所以在TDD网络下,当所述用户设备只有一个下行射频链,该方法还包括:For a traditional non-CA UE, it can only be connected to the same site, and the two RFs work on the uplink and downlink respectively. Under the FDD network, because the uplink and downlink are different frequency points, the uplink RF and the downlink RF need to work at the same time. However, In a TDD network, when the uplink RF is working, the downlink RF is idle, and when the downlink RF is working, the uplink RF is idle. In order to improve the utilization rate of the RF of the user equipment, in the TDD network, the idle RF can be enabled. When the idle RF is enabled, the user equipment can be regarded as a device with two downlink RFs, so the two The RF respectively receives the downlink data sent by the macro base station and the small base station. Therefore, under the TDD network, when the user equipment has only one downlink radio frequency chain, the method further includes:

用户设备接收宏基站发送的所述第二控制指令,并根据所述第二控制指令使用上行RF在所述上行子帧集的位置接收所述小基站发送的下行数据,并在所述上行子帧集中的最后一个子帧切换回上行RF。The user equipment receives the second control instruction sent by the macro base station, and uses the uplink RF to receive the downlink data sent by the small base station at the position of the uplink subframe set according to the second control instruction, and receives the downlink data sent by the small base station in the uplink subframe set The last subframe in the frame set switches back to the uplink RF.

本发明实施例所提供的方法中,当工作在不同频率的宏基站和小基站同时为UE提供服务时,用户设备UE为了能够合理的利用自身的射频链资源,将唯一的上行射频链在不同的基站之间切换,从而能够将宏基站和小基站发送的数据的反馈信息对应的反馈给宏基站和小基站。In the method provided by the embodiment of the present invention, when the macro base station and the small base station working at different frequencies provide services for the UE at the same time, the user equipment UE uses the only uplink radio frequency chain in order to reasonably use its own radio frequency chain resources. handover between the base stations, so that the feedback information of the data sent by the macro base station and the small base station can be fed back to the macro base station and the small base station correspondingly.

另外,在TDD网络下,当用户设备只设置有一个上行射频链和一个下行射频链时,为了提高UE的RF利用率,则可以将原本用于上行的RF切换到下行,从而将原来用于分别接收上行和下行的两个RF同时用于接收宏基站和小基站的下行数据,从而达到双链接网络的增益。In addition, in a TDD network, when the user equipment is only provided with one uplink radio frequency chain and one downlink radio frequency chain, in order to improve the RF utilization rate of the UE, the RF originally used for uplink can be switched to downlink, so that the RF originally used for uplink can be switched to downlink. The two RFs that respectively receive the uplink and downlink are used to receive the downlink data of the macro base station and the small base station at the same time, so as to achieve the gain of the dual-link network.

为了更清楚详细的说明本发明实施例所提供的方法,以下利用表1所提供的LTETDD系统中的上下行配置对本发明实施例所提供的方法做进一步的说明,具体为:In order to describe the method provided by the embodiment of the present invention in more detail, the method provided by the embodiment of the present invention is further described by using the uplink and downlink configuration in the LTE TDD system provided in Table 1, specifically:

第一种情况:Macro eNB和Small eNB分别以TDD工作方式工作;UE有两个下行RF和一个上行RF;Macro eNB和Small eNB工作在不同频率;并且UE采用上下行配置类型1;则本发明实施例所提供的方法的具体实现包括:The first case: Macro eNB and Small eNB work in TDD mode respectively; UE has two downlink RFs and one uplink RF; Macro eNB and Small eNB work at different frequencies; and UE adopts uplink and downlink configuration type 1; then the present invention The specific implementation of the method provided by the embodiment includes:

Macro cell和Small cell分别在各自工作的频点上以TDD配置发送下行数据,UE可以通过两个下行RF正常接收两个基站的数据;然后由于UE只有一个上行的RF射频链,由于下行数据同时到达,UE无法按照传统使用的HARQ RTT timer的时序同时对Macro cell和Small cell进行反馈,所以需要利用本发明实施例所提供的方法确定UE针对上行反馈宏基站和小基站的子帧,具体实现为:The Macro cell and the Small cell send downlink data in TDD configuration on their respective operating frequencies, and the UE can normally receive the data from the two base stations through the two downlink RFs; and since the UE has only one uplink RF radio frequency chain, the downlink data simultaneously Arrival, the UE cannot simultaneously feed back the Macro cell and the Small cell according to the timing of the traditionally used HARQ RTT timer, so it is necessary to use the method provided by the embodiment of the present invention to determine the subframes of the UE for the uplink feedback of the macro base station and the small base station. for:

将UE的上行RF资源根据时间分配给Macro cell或者Small cell,在下行配置类型1中,一个包括10个子帧的无线帧中,有两个上行子帧集,第一子帧集包括子帧2、3;第二子帧集包括子帧7、8。所以在该实例中宏基站和小基站可以协调使用这两个子帧集,所以在实施例中,宏基站确定第一子帧集和第二子帧集合之间的时间间隔之后,就可以根据该时间间隔确定自身和小基站的HARQ RTT timer。则在该实施例中,宏基站和小基站使用一个无线帧的具体实现可以是:Allocate the UE's uplink RF resources to the Macro cell or Small cell according to the time. In the downlink configuration type 1, there are two uplink subframe sets in a radio frame including 10 subframes, and the first subframe set includes subframe 2. , 3; the second subframe set includes subframes 7 and 8. Therefore, in this example, the macro base station and the small base station can coordinate the use of these two subframe sets, so in the embodiment, after the macro base station determines the time interval between the first subframe set and the second subframe set, it can The time interval determines the HARQ RTT timer of itself and the small base station. Then in this embodiment, the specific implementation of using one radio frame between the macro base station and the small base station may be:

如图6所示,对于2;3号子帧(即第一子帧集),UE的上行RF工作在small cell所在的频点,用于反馈Small cell的下行数据的ACK/NACK。对于7;8号子帧(即第二子帧集),UE的上行RF工作在Macro cell所在的频点,用于反馈Macro cell的下行数据的ACK/NACK。As shown in FIG. 6, for subframes 2 and 3 (ie, the first subframe set), the uplink RF of the UE works at the frequency point where the small cell is located, and is used to feed back ACK/NACK of the downlink data of the small cell. For subframes 7 and 8 (that is, the second subframe set), the uplink RF of the UE works at the frequency point where the Macro cell is located, and is used to feed back ACK/NACK of the downlink data of the Macro cell.

当UE在上行子帧结束(下一个子帧是下行子帧),UE的RF需要转换到Macro cell所在的频点,即RF Retuning。When the UE ends an uplink subframe (the next subframe is a downlink subframe), the RF of the UE needs to switch to the frequency point where the Macro cell is located, that is, RF Retuning.

第二种情况:Macro eNB和Small eNB分别以FDD工作方式工作;UE的有两个下行RF和一个上行RF;Macro eNB和Small eNB是工作在不同频率上。The second case: Macro eNB and Small eNB work in FDD mode; UE has two downlink RFs and one uplink RF; Macro eNB and Small eNB work on different frequencies.

如图7所示,因为当Macro eNB和Small eNB分别以FDD工作方式工作时,网络侧Macro eNB和Small eNB协商UE RF Retuning的时间,网络需要下发给UE关于RF Retuning的时间。在该实施例中,因为Macro eNB和Small eNB分别以FDD工作方式工作,所以对应上行射频链来说就不需要考虑下行数据所占用的子帧,只需要确定上行射频链切换到不同基站时,出现的RF Retuning的时间。如图7所示,在第一行表示Macro eNB的下行链路;第二行为Small eNB的下行链路;第三行,是UE上行的分配情况,所以在该实施例中,UE上行链路中一个无线帧的第一子帧集(N,N+1,N+2,N+3)和第二子帧集(N+5,N+6,N+7,N+8)之间的子帧(N+4)用来实现RF Retuning。所以如果第一子帧集UE进行宏基站的下行反馈,则第二子帧集进行小基站的下行反馈。As shown in Figure 7, because when the Macro eNB and the Small eNB work in the FDD mode, the Macro eNB and the Small eNB on the network side negotiate the RF Retuning time of the UE, and the network needs to send the RF Retuning time to the UE. In this embodiment, since the Macro eNB and the Small eNB work in the FDD mode respectively, there is no need to consider the subframes occupied by the downlink data for the uplink radio frequency chain, and only need to determine when the uplink radio frequency chain is switched to different base stations, The time of RF Retuning that appears. As shown in Figure 7, the first row represents the downlink of the Macro eNB; the second row represents the downlink of the Small eNB; Between the first subframe set (N, N+1, N+2, N+3) and the second subframe set (N+5, N+6, N+7, N+8) in a radio frame The subframe (N+4) is used to implement RF Retuning. Therefore, if the UE in the first subframe set performs downlink feedback of the macro base station, then the second subframe set performs downlink feedback of the small base station.

第三种情况:Macro eNB和Small eNB分别以TDD工作方式工作;UE有一个下行RF和一个上行RF;Macro eNB和Small eNB是工作在不同频率上;并且UE采用上下行配置类型1;则本发明实施例所提供的方法的具体实现包括:The third case: Macro eNB and Small eNB work in TDD mode respectively; UE has one downlink RF and one uplink RF; Macro eNB and Small eNB work on different frequencies; and UE adopts uplink and downlink configuration type 1; then this The specific implementation of the method provided by the embodiment of the invention includes:

对于一个传统的非CA的UE只能同一个站点链接,两个RF分别工作在上行和下行,在FDD网络下,因为上下行是不同的频点,因此需要上行RF和下行RF同时工作,然而在TDD网络下,当上行RF工作的时候,下行RF是空闲的,当下行RF工作的时候,上行RF是空闲的。For a traditional non-CA UE, it can only be connected to the same site, and the two RFs work on the uplink and downlink respectively. Under the FDD network, because the uplink and downlink are different frequency points, the uplink RF and the downlink RF need to work at the same time. However, In a TDD network, when the uplink RF is working, the downlink RF is idle, and when the downlink RF is working, the uplink RF is idle.

在双链接网络中,由于一个UE可以有两个站同时为其服务,对于只有一个上行和一个下行RF的UE充分利用空闲的RF,当双链接网络的Macro cell和Small cell都是TDD模式,利用本发明实施例所提供的方法使用UE的上下行射频链可以获得双链接网络在吞吐量上的增益。具体实现可以是:In a dual-link network, since a UE can have two stations serving it at the same time, for a UE with only one uplink and one downlink RF, make full use of the idle RF. When the Macro cell and Small cell of the dual-link network are both in TDD mode, By using the method provided by the embodiment of the present invention, the uplink and downlink radio frequency chains of the UE can be used to obtain the throughput gain of the dual link network. The specific implementation can be:

如图8所示,Macro cell和Small cell分别在各自工作的频点上以TDD配置发送下行数据。As shown in FIG. 8 , the Macro cell and the Small cell send downlink data in TDD configuration on their respective working frequency points.

如果当前子帧是下行子帧,UE的下行RF接收来自Macro cell的数据,UE的上行RF工作这个时候也用于接收数据,接收来自small cell的下行数据。If the current subframe is a downlink subframe, the downlink RF of the UE receives data from the Macro cell, and the uplink RF of the UE is also used to receive data at this time, receiving downlink data from the small cell.

如果当前子帧是上行子帧,UE的下行RF,经过RF retuning工作在Macro所在的上行频点,如图8所示,在0;1子帧UE的下行RF接收Macro cell的下行数据,对于2;3号子帧UE的下行RF变成上行模式,用于反馈下行数据和传输上行业务。If the current subframe is an uplink subframe, the downlink RF of the UE works at the uplink frequency point where the Macro is located after RF retuning. As shown in Figure 8, the downlink RF of the UE receives the downlink data of the Macro cell in the 0; 1 subframe. The downlink RF of the UE in subframes 2 and 3 changes to uplink mode, which is used to feed back downlink data and transmit uplink services.

采用相同的方法,UE的上行RF,在0;1;4;5;6;9号子帧上用于接收Small cell的下行数据,对于2;3;7;8号子帧UE的上行RF用于反馈和传输上行业务。Using the same method, the uplink RF of the UE is used to receive the downlink data of the Small cell on subframes 0; 1; 4; 5; 6; 9, and the uplink RF of the UE in subframes 2; 3; 7; 8 Used for feedback and transmission of uplink services.

另一个问题是硬件上下行转换操作(图中标识为RF retuning),当UE的下行RF在0;1号子帧上工作的时候,在2;3号子帧需要工作在上行方式,由于将RF由下行变成上行可能需要硬件的操作(类似RF retuning),网络侧需要配置转换操作。Another problem is the hardware uplink and downlink conversion operation (identified as RF retuning in the figure). When the UE's downlink RF works on subframe 0; 1, it needs to work in uplink mode in subframe 2; 3. Switching RF from downlink to uplink may require hardware operations (similar to RF retuning), and the network side needs to configure conversion operations.
