Description

一种导频序列的生成方法、用户设备、基站 A method for generating a pilot sequence, the user equipment, the base station

技术领域 FIELD

[0001] 本发明涉及无线通信技术领域,具体涉及一种导频序列的生成方法、装置。 [0001] The present invention relates to wireless communication technologies, and particularly relates to a pilot sequence generation method, apparatus.

[0002] 背景技术 [0002] BACKGROUND OF THE INVENTION

[0003] 3GPP LTE系统下行传输会采用用户设备(UE)专用导频信号(UESpecificReference Signal)进行波束复形(Beamforming)模式的数据信道解调。 [0003] 3GPP LTE downlink transmission system uses the user equipment (UE) a dedicated pilot signal (UESpecificReference Signal) beam-shaped multiplexed data channel (Beamforming) mode demodulation. LTE增强(LTE-Advance)系统的下行数据信道均采用UE专用导频信号进行解调。 LTE-Advanced (LTE-Advance) system, downlink data channels are used UE-specific pilot signal is demodulated.

[0004] 终端通过导频信号进行数据解调的具体过程包括:接收导频信号,根据该导频信号进行传输信道响应估计,再根据估计出来的信道响应,检测出发射端的数据信号。 [0004] The specific process of the terminal performs data demodulation by the pilot signal comprises: receiving a pilot signal, transmission channel response estimate based on the pilot signal, then in accordance with the estimated channel response, detecting a data signal the transmitting end.

[0005] 其中,根据该导频信号进行传输信道响应估计包括,接收端已知发送端发送的导频信号携带的导频序列,在本地生成接收端的导频序列,接收端接收经过空间传输后的导频信号,根据接收的导频信号和已知的发送导频序列,获知导频信号的空间传输信道的信道响应,由于数据信号和导频信号经历相同的空间传输信道,因此,也就得到数据信号的传输信道响应。 After spatial transmission after [0005] wherein, based on the pilot signal transmission channel response estimation comprises receiving end the known pilot sequence guide sender sends the pilot signal carrying generates receiving side pilot sequence in the local receiver to receive pilot signal, according to the frequency sequence of the received pilot signal and the known transmitted pilot learns channel pilot spatial transmission channel signal response, since the data signal and the pilot signal undergoes the same spatial transmission channel, and therefore, it to obtain a data signal transmission channel response.

[0006] 在蜂窝通信系统,不同小区采用不同的导频序列,以实现导频信号间干扰随机化,减少小区间干扰的影响。 [0006] In cellular communication systems, different cells use different pilot sequences to achieve pilot signal interference randomization, reduce the influence of inter-cell interference. 导频序列通常由伪随机(PN)序列生成,相同的移位寄存器结构下,不同的移位寄存器初始化序列对应生成不同的PN序列。 Pilot sequence are typically generated by a pseudo-random (PN) sequence, under the same shift register structure, different initialization sequence corresponding to the shift register to generate different PN sequence.

[0007] LTE以及LTE-Advance都需要增强下行吞吐量,多UE空间复用是一种有效的性能增强方式,LTE增强下行吞吐量采用增加下行多UE beamforming的方式,而LTE-Advance增强下行吞吐量采用在LTE多UE空间复用传输模式基础上进行增强设计。 [0007] LTE and LTE-Advance require enhanced downlink certain UE multi-spatial multiplexing is an effective way to enhance performance, LTE downlink enhance certain UE multi Beamforming way to increase the downlink, the LTE-Advance downlink throughput enhancement on the basis of the amount of use of LTE UE multiple spatial multiplexing transmission mode on the enhanced design. 多UE空间复用传输模式具体指,不同UE的数据通过空间复用在相同的时频资源上传输。 Multiple spatial multiplexing transmission mode UE specifically refers to the data of the UE through different spatial multiplexing transmission on the same time-frequency resource. 但是,多UE空间复用传输模式下,由于空间信道不能保证完全正交,复用在一起的UE数据之间会存在相互干扰。 However, the multi-UE spatial multiplexing transmission mode, the channel can not be guaranteed due to space completely orthogonal, multiplexing will interfere with each other between a UE data together.

[0008] 现有技术中有两种干扰消除办法,一种干扰消除方法是UE可以先根据干扰UE的专用导频信号获得干扰UE的传输信道响应,进行干扰UE数据的解调,获得发射给干扰UE的数据,根据发射给干扰UE的数据恢复出UE接收的数据信号中的干扰UE数据信号分量,并将该干扰UE数据信号分量从接收信号中减去,从而进行干扰消除;另一种干扰消除方法是UE可以根据本UE的传输信道响应和干扰本UE传输信道响应生成信道矩阵,进行多用户数据符号联合检测,从而进行干扰消除。 [0008] In the prior art there are two approaches to eliminate interference A method of interference cancellation is first UE may be obtained according to the UE dedicated pilot interference pilot signal transmission channel interfering UE response, interfering UE demodulates the data to obtain the transmit UE interference data, according to the data transmitted to the interfering UE to recover the data signal received by the UE UE interference signal component data, and the UE interfering signal component data is subtracted from the received signal so as to perform interference cancellation; other UE interference cancellation method according to the transmission channel response of this interference present and the UE UE generates a transmission channel response channel matrix, multi-user joint detection of data symbols, to perform interference cancellation.

[0009] LTE系统中现有的UE专用导频序列的初始化序列中包含数据信道所属UE的UEID,则不同UE的专用导频序列不同。 UEID initialization sequence [0009] LTE system existing UE-specific pilot sequence comprises a data channel belongs to a UE, the UE is different dedicated pilot sequences differ. 在多UE空间复用传输模式下,如果采用LTE的专用导频序列,无法获知干扰UE的信道,不能进行干扰消除,降低了系统的性能。 In the multi-UE spatial multiplexing transmission mode, if a dedicated pilot sequence LTE, UE can not know the channel interference, the interference can not be eliminated, reducing the performance of the system.

[0052] 具体实施方式 [0052] DETAILED DESCRIPTION

[0053] 为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部份实施例,而不是全部的实施例。 [0053] To make the objectives, technical solutions, and advantages of the present invention will become apparent in conjunction with the accompanying drawings below of the present invention will be further described in detail, obviously, the described embodiments are merely part of embodiments of the invention, rather than all embodiment. 基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。 Based on the embodiments of the present invention, all other embodiments of ordinary skill in the art without any creative effort shall fall within the scope of the present invention.

[0054] 多UE空间复用模式下,不同UE的导频信号可以采用时分、频分或码分的正交方式发射,接收端区分不同UE的导频信号。 [0054] Spatial multiplexing multi-mode UE, UE different pilot signals may be time division, frequency division, or code division quadrature transmitter, the receiver to distinguish the pilot signals of different UE. 单流beamforming传输模式的数据信道采用UE专用导频信号进行解调,基站导频序列的初始化序列生成式中除了包含小区标识(cell ID)之外还包含数据信道所属UE的用户标识(UEID)。 Single stream beamforming transmission mode data channel using UE-specific pilot signal user identification initialization sequence formula demodulation, the base station pilot sequences in addition to containing the cell identification (cell ID) than further comprising a data channel belongs to a UE (UEID) .

[0055] 其中,专用导频序列的初始化序列初始化公式可以为: [0055] wherein, the initialization sequence initialization formula dedicated pilot sequence may be:

[0056] [0056]

Cinit =(k/2」+ l).(2iC+1).216+«贿【 Cinit = (k / 2 "+ l). (2iC + 1) .216+« [bribery

[0057] 上述公式中,Cinit为初始化序列;ns为时隙序号;NIDee11为Cell ID ;nENTI为UE ID。 [0057] In the above formula, Cinit initialization sequence; NS is the slot number; NIDee11 for the Cell ID; nENTI is a UE ID.

[0058] 因为UE ID是网络侧为单个小区内每个用户分配的一个特有的用户标识。 [0058] Because the UE ID is unique to a network side in a single-cell user identification allocated to each user. 多空间复用传输模式下,需要根据干扰UE的导频序列,获得干扰UE的信道,但是由于导频序列的初始化序列中包含数据信道所属UE的UE ID,则不同UE的专用导频序列不同。 Multi spatial multiplexing transmission mode, pilot sequence according to the guide interfering UE, obtain the channel interference of the UE, but because of the initialization sequence of the pilot sequence comprises UE ID data channel belongs to a UE, the dedicated pilot different UE pilot different sequences . 在多UE空间复用传输模式下,如果采用LTE的专用导频序列,无法获知干扰UE的信道,进而不能进行干扰消除,降低了系统的性能。 In the multi-UE spatial multiplexing transmission mode, if a dedicated pilot sequence LTE, UE can not know the channel interference, interference cancellation can not be further reduced system performance.

[0059] 本发明实施例要解决的主要技术问题是提供一种导频序列的生成方法支持在多UE空间复用传输模式下进行UE间干扰消除,提高了系统性能。 [0059] The main technical problem to be solved by embodiments of the present invention to provide a method for generating a pilot sequence guide support between the UE interference canceller in the multi-UE spatial multiplexing transmission mode, system performance is improved.

[0060] 下面通过具体的实施例,分别进行详细的说明。 [0060] By the following specific examples are carried out separately described in detail.

[0061] 请参阅图1,为本发明实施例中一种导频序列的生成方法第一实施例,可以包括: [0061] Referring to FIG. 1, an embodiment of one pilot sequence generating method of the first embodiment, the present invention may comprise:

[0062] 101、生成用户设备UE专用导频序列的初始化序列,该初始化序列的生成式中仅包含UE共知参数; [0062] 101, the user equipment UE generates specific pilot sequences the initialization sequence, the initialization sequence of the formula contains only parameter known to UE;

[0063] 该UE的共知参数可以包括cell ID,则在在多点协作CoMP传输模式下该,该cellID为UE驻扎小区的cell ID ;UE的共知参数还可以包括小区组标识(cell group ID),则在多点协作CoMP传输模式下,该cell group ID为CoMP小区组的cell group ID。 [0063] The UE is commonly known parameters may include a cell ID, then the in coordinated multi-point CoMP transmission mode, the cellID the UE camped cell of cell ID; UE co-known parameters may further include a cell group identity (cell group ID), then in CoMP coordinated multi-point transmission mode, the cell group ID for the cell group ID CoMP cell group.

[0064] 公式(2)为UE专用导频序列的初始化序列的生成式,具体可以为: [0064] Equation (2) is a formula of the initialization sequence UE dedicated pilot sequences may specifically be:

[0066] 根据公式⑵可知,UE共知参数可以包括但不限于Cinit、ns、NIDee11,其中Cinit为初始化序列,ns为时隙序号,N1:11为Cell ID或Cell group ID。 [0066] According to the formula ⑵ understood, UE commonly known parameters may include but are not limited to Cinit, ns, NIDee11, wherein CINIT initialization sequence, ns is a slot number, N1: 11 is the Cell ID or Cell group ID.

[0067] 其中cell group ID为多个小区共同的一个小区组标识,小区组具体的可以为多点协作CoMP传输方式的多个小区组成的小区组。 [0067] wherein the cell group ID to a plurality of common cell identity of a cell group, the cell may be a particular set of the plurality of coordinated multi-cell CoMP transmission mode of the group consisting of a cell. 在CoMP传输方式下,属于同一个基站或不同基站下的多个小区同时协作处理一个用户数据的接收与发送,该多个小区组成一个CoMP小区组,在小区组中,有一个小区是UE初始接入的驻扎小区,在CoMP小区组内,每小区组有独立的cell ID,一个CoMP小区组,也会有一个cell group ID,CoMP小区组内的多个小区发送给UE的导频序列的初始化序列生成式中包含UE驻扎小区的cell ID或进行多点协作小区组的cell group ID。 In the CoMP transmission mode, or a plurality of base stations belonging to the same cell under different base stations collaborate simultaneously receive and transmit data to a user, the plurality of cells to form a CoMP cell group in the cell group, a cell is a UE initially access camped cell, in the CoMP cell groups, each cell group has a separate cell ID, a CoMP cell group, there will be a cell group ID, a plurality of cells in the CoMP cell group is sent to the UE pilot sequence formula initialization sequence comprises a cell ID UE camping in a cell or cell group ID for the multi-cell cooperative group.

[0068] 102、根据该初始化序列生成UE的专用导频序列。 [0068] 102, the initialization sequence based on the dedicated pilot pilot sequence generated UE.

[0069] 由于cell ID或cell group ID是小区内UE公知的参数,因此通过其进行专用导频序列初始化,UE可以获知小区内该UE的专用导频序列。 [0069] Since the cell ID or cell group ID within the cell of the UE is known parameters, the initialization sequence through its dedicated pilot, the UE may know UE dedicated pilot pilot sequence within a cell. 因为干扰UE的导频序列与该UE具有相同的cell ID或cell group ID,所以根据导频序列初始化序列中的cell ID或cellgroup ID可以获得干扰UE的导频序列。 Because the interfering UE pilot sequences having the same cell ID or cell group ID to the UE, so that the pilot sequence initialization sequence cellgroup ID or cell ID guide UE may obtain an interference pilot sequence.

[0070] 基站可以设定多种类型的专用导频序列,分别用于不同的多天线传输模式的专用导频信号,多天线模式可分为:单UE多天线传输模式和多UE空间复用传输模式; [0070] The base station may set a plurality of types of dedicated pilot sequences, each for a different multi-antenna transmission mode dedicated pilot signals, multi-antenna mode can be divided into: single UE multi-mode and multi-antenna transmission spatial multiplexing UE transmission mode;

[0071] 其中,该初始化序列生成UE的专用导频序列,该初始化序列生成式中包含小区标识或小区组标识,不包含UE标识的专用导频序列,可以用于多UE空间复用模式的UE ; [0071] wherein, the initialization sequence generated UE dedicated pilot sequence, wherein the sequence generator initialization comprises a cell identity or a cell group ID, the UE identity does not include dedicated pilot pilot sequence, can be used for multiple spatial multiplexing mode UE UE;

[0072] 进一步,还包括,生成用于单UE空间复用模式的UE专用导频序列的初始化序列,该UE专用导频序列的初始化序列生成式中包含UE ID。 [0072] Further, further comprising generating a UE-specific initialization sequence by single spatial multiplexing mode UE pilot sequence, the UE-specific pilot initialization sequence comprises a sequence of formula UE ID.

[0073] 如果多天线传输模式相对于该单UE来说是透明的,即该单UE不需要知道其数据信道使用的多天线传输模式,则基站通过高层信令或物理层控制信令携带指示信息通知UE使用的专用导频序列的类型,提高了系统灵活性,也保证了LTE系统的后向兼容性。 [0073] If the multi-antenna transmission mode with respect to the single UE is transparent, i.e. the UE does not need to know which single data channel multi-antenna transmission mode, the base station carries indicated by higher layer signaling or physical layer signaling control UE using the dedicated pilot information notifying pilot type sequence, to improve the flexibility of the system, the LTE system also ensures the backward compatibility.

[0074] 本实施例中,生成UE专用导频序列的初始化序列,该初始化序列的生成式中仅包含UE共知参数,根据该初始化序列生成UE的专用导频序列,因为干扰UE的导频序列与该UE具有相同的cell ID或cell group ID,所以根据导频序列初始化序列中的cell ID或cell group ID可以获得干扰UE的导频序列,进而获得干扰UE的信道,进行干扰消除,提高系统性能。 [0074] In this embodiment, to generate the initialization sequence of pilot sequences UE dedicated pilot, formula of the initialization sequence includes only UE commonly known parameters, pilot sequences based on the initialization sequence to generate a UE dedicated pilot, since the interfering UE pilot sequence with the UE having the same cell ID or cell group ID, so in accordance with cell ID pilot sequence initialization sequence or cell group ID can be obtained interference pilot sequence UE, thereby obtaining channel interfering UE, interference cancellation, improved system performance.
