技术领域 FIELD

[0001] 本申请涉及通信技术领域,特别是涉及一种TD-SCDMA小区的载波间功率分配方法,以及,一种TD-SCDMA小区的载波间功率分配系统。 [0001] The present application relates to communication technologies, particularly to a TD-SCDMA cell inter-carrier power allocation method, and a TD-SCDMA cell inter-carrier power distribution system.

背景技术 Background technique

[0002] TD-SCDMA的功率池技术,是指以N载波总功率为功率池,进行载波间功率共享。 [0002] TD-SCDMA cell technology power, N refers to the total power of the carrier power of cell, the inter-carrier power sharing. 目前,TD-SCDMA的每个小区包含N个载波,公传信道配置在主载波的TSO时隙,使用功率池技术后,允许主载波TSO时隙和DwPCH(下行导频信道)时隙使用N载波的总功率进行发射,可以增大小区公传信道的覆盖范围。 At present, TD-SCDMA cells each comprising N carriers, well-pass channel arranged in the primary carrier time slots TSO, the use of power pooling, allowing time slots TSO and DwPCH primary carrier (downlink pilot channel) using N time slots the total transmit power of the carrier can be increased well-cell signaling channel coverage.

[0003] 业务时隙的功率池启动取决于对单载波的功率需求,小容量大覆盖是建网初期的主要特征,这种特征主要表现为用户数量较少,各载波间的用户分布不十分均匀;覆盖尚未进行成熟的优化,尚有部分区域覆盖不足。 [0003] service time slot of the power pool to start depends on single-carrier power requirements, small-capacity coverage is the main feature of the initial network construction, this feature mainly for the small number of users, carriers that are distributed among the users is not very uniformity; optimized covering not yet mature, there are some areas insufficient coverage. 通常情况下,由于用户分布在小区的不同位置,真正需要基站满功率发射的情况并不多见,各载波的功率同时达到极限的情况更少。 Typically, since the user of cells distributed over different locations, where the real needs of the base station transmitted at full power are rare, while the power of each carrier reaches less limiting case. 如果某个载波由于用户所处位置等原因造成覆盖不足时,可以借用其他载波的功率以满足此用户业务质量的需求。 If a carrier due to user location, etc., causing insufficient coverage, other carriers can borrow power to meet the needs of the user service quality. 此时,便可在小区内启动功率池功能。 At this time, the starting power can function in the cell pool. 载波间的功率分配主要依靠各载波的期望功率来进行分配:当总功率能满足各载波总需求时,各载波按需分配;当总功率不能满足各载波总需求时,在保证其他载波功率在满足使用的前提下根据各载波的需求按比例分配,达到最大限度利用功率资源的目的。 Power distribution among major carriers rely on each carrier's expected power to be allocated: When the total power can meet the total needs of carriers, each carrier on demand; when the total power can not meet the total needs of carriers, other carriers to ensure power the proportion allocated based on the premise meet the needs of each carrier, to achieve maximum utilization of the power resource.

[0004] 辅载波TSO支持配置码道后,关于主载波与辅载波间TSO功率如何分配,现有技术中的实现方案包括如下几种: [0004] After the secondary carrier support TSO code channel configuration, on the primary carrier and the secondary carrier between TSO how to allocate power, prior art implementations include the following:

[0005] (I)TSO采用业务时隙功率池的实现方案。 [0005] (I) TSO implementation using a power cell traffic slots.

[0006] (2)在配置时保证各载波TSO功率和不超过整个小区的功率(无天线故障),在天线故障时辅载波TSO不分配功率。 [0006] (2) to ensure that each carrier power and power TSO (no antenna failure) does not exceed the whole cell configuration, TSO secondary carrier when the antenna is not allocated power failure.

[0007] (3)在配置时保证各载波TSO功率和不超过整个小区的功率(无天线故障),在天线故障时按目前的有效天线数占总天线数的比例对公传信道功率进行等比例下降。 [0007] (3) to ensure that each carrier TSO power and power (no antenna failure) does not exceed the entire cell in the configuration, according to the current number of active antennas ratio of the number of antennas of well-pass channel power for the total time of antenna failure decline in the proportion.

[0008] 然而,上述现有技术存在以下缺点: [0008] However, the above-described prior art has the following disadvantages:

[0009] 对于实现方案(I)而言,此方案需要动态传送各载波的需求功率,涉及产品的许多环节,流程复杂,降低了产品的稳定性。 [0009] For the implementation (I), the need to dynamically transmit this embodiment each carrier power demand, many areas involving the product, process complexity, reduce the stability of the product. 实际上,为了产品的稳定,在现网中一般不开启业务时隙功率池功能。 In fact, in order to stabilize the product, in the current network business is generally not open slot power pool function.

[0010] 对于实现方案(2)而言,在天线故障时不能使用辅载波TSO承载业务或公传信道,降低了无线资源利用率。 [0010] For the implementation (2), the secondary carrier can not be used well TSO bearer service or transmission channel when an antenna failure, reducing the radio resources utilization.

[0011] 对于实现方案(3)而言,在天线故障时会导致小区覆盖范围缩小。 [0011] For implementation (3), it will lead to failure when the antenna coverage shrinks.

[0012] 因此,目前本领域技术人员迫切需要解决的一个技术问题为,创造性地提出一种TD-SCDMA小区载波间的功率分配机制,用以保证产品的稳定性,提高无线资源的利用率,并在天线故障时能够优先为主载波公传信道分配功率,尽量保证小区的覆盖范围,同时避免过功率的发生。 [0012] Accordingly, a technical problem to those skilled in the current urgent to creatively proposed power distribution mechanism between a TD-SCDMA cell carrier to ensure the stability of the product, to improve the utilization of radio resources, and when an antenna failure based carrier capable of preferentially allocated power is well downstream channels, try to ensure coverage of a cell, while avoiding the occurrence of excessive power.

具体实施方式 Detailed ways

[0110] 为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本申请作进一步详细的说明。 [0110] The above object of the present application, features and advantages can be more fully understood in conjunction with the accompanying drawings and the following specific embodiments of the present application will be further described in detail.

[0111] 一般而言,N频点TD-SCDMA小区包括I个主载波和N-1个辅载波,公传信道一般只配置在主载波TSO上,辅载波TSO —般不配置码道,此时主载波TSO可以使用整个小区的功率资源进行发射。 [0111] In general, N TD-SCDMA cell frequency point I comprising a primary carrier and the N-1 secondary carrier, generally well-pass channel arranged in the TSO on the primary carrier, the secondary carrier TSO - like code channel is not configured, this when TSO primary carrier power resource can be used to transmit the entire cell.

[0112]目前网络配置只有主载波TSO配置公传信道,辅载波的TSO禁止使用,这样在载波数配置较多时(目前外场配置基本都是6载波或者9载波),辅载波TSO资源浪费比较严重,如果为9载波配置,主载波公共信道占用3个载波的功率资源,剩余6个载波的TSO就等价于一个载波的所有资源,禁止使用会造成资源严重浪费。 [0112] The current network configuration only primary carrier TSO disposed well downstream channels, the auxiliary carrier TSO prohibited, so that when the number of carriers arranged large (current field configuration basically 6 carriers or 9 carriers), secondary carrier TSO waste of resources more serious If the carrier 9 is arranged, the primary carrier power of a common channel resource occupied by three carriers, the remaining six carriers TSO is equivalent to all the resources of a carrier, prohibit the use can cause serious waste of resources.

[0113] 如果辅载波TSO配置码道(如FPACH (快速物理接入信道)/PDSCH (物理下行共享信道)/DPCH(专用物理信道)等),即会存在主辅载波间TSO功率如何分配的问题,要求各个载波发送功率之和不能超过整个小区的功率资源,否则会出现过功率的情况,如果过功率持续时间较长有可能烧毁RRU(射频拉远模块)硬件。 [0113] If the secondary carrier TSO configuration code channel (e.g., the FPACH (Fast Physical Access Channel) / PDSCH (Physical Downlink Shared Channel) / DPCH (Dedicated Physical Channel), etc.), i.e., there will be between the primary and secondary carrier TSO power how to distribute questions to ask each carrier transmission power can not exceed the power resources of the entire district, there would be the case had the power, if power over a longer duration may be burned RRU (remote radio module) hardware. 载波间功率分配算法,需要保证各个载波发送功率之和不超过整个小区的功率资源。 Inter-carrier power allocation algorithm, the transmission power of each carrier need to ensure that does not exceed the power resources of the entire cell.
