传输方式的指示方法及装置 Indication method and apparatus for transmission

技术领域 FIELD

[0001] 本发明涉及通信领域,具体而言,涉及一种传输方式的指示方法及装置。 [0001] The present invention relates to communication field, particularly, to a transmission apparatus and a method of indicating.

背景技术 Background technique

[0002] 在无线通信中,如果在发送端(例如,基站,简称为eNB)使用多根天线,可以采取空间复用的方式来提高传输速率,即,在发送端相同的时频资源上的不同天线位置发射不同的数据,在接收端(例如,用户设备,简称为UE)也使用多根天线,可以在单用户的情况下将所有天线的资源都分配给同一用户,这传输形式叫做单用户多输入多输出(Single User-Multiple Input Multiple Output,简称为SU-MIMO),另外,也可以在多用户的情况下将不同天线空间的资源分配给不同用户,这传输形式叫做多用户MIMO(MultipleUserMIMO,简称为MU-MIMO)。 [0002] In wireless communications, if the transmitting side (e.g., base station, simply referred to as eNB) using a plurality of antennas, may take the form of spatial multiplexing to increase the transmission rate, i.e., in the same transmission end time-frequency resources different antenna positions different data are transmitted, at the receiving end (e.g., a user equipment, abbreviated to UE) also uses a plurality of antennas may be assigned resources for all antennas in the case of single-user to the same user, which transmission form is called single user MIMO (Single user-multiple input multiple output, abbreviated as SU-MIMO), is also possible to allocate resources for different antenna space to different users in a multi-user, this form of transmission is called multi-user MIMO ( MultipleUserMIMO, referred to as the MU-MIMO). 传输系统如果要在同时间支持单用户MIMO和多用户MIMO, eNB是有必要用控制信令向UE提供在这两种传输模式下的数据。 If the transmission system at the same time to support single-user MIMO and multi-user MIMO, eNB is necessary to provide a data transmission mode in both control signaling to the UE. UE在这两种传输模式都需要知道eNB对于该UE传输所用的秩(Rank),在单用户模式下,因为所有天线的资源都分配给同一用户,传输所用的层数就等于eNB在该传输所用的秩;而在多用户传输中,对应一个用户传输所用的层数是少于该传输的总层数。 UE in these transport modes needs to know eNB for rank (Rank) of the UE used for transmission, in single-user mode, because the resources of all antennas are assigned to the same user, transfer the number of layers is equal eNB in ​​the transport as used rank; in a multi-user transmission, a user corresponding to the number of layers used for transmission of the transmission is less than the total number of layers. 要做到单用户和多用户传输的动态切换,eNB需要在不同传输模式下通知UE不同的资料。 To achieve dynamic switching of single-user and multi-user transmission, eNB UE needs to inform different data in different transmission modes. [0003] 长期演进(Long-Term Evolution,简称为LTE)的版本号8(Release 8)中定义了以下三种下行物理控制信道:物理下行控制格式指示信道(Physical Control Format IndicatorChannel,简称为PCFICH)、物理混合自动重传请求指示信道(Physical Hybrid AutomaticRetransmission Request Indicator Channel,简称为PHICH)和物理下行控制信道(PhysicalDownlink Control Channel ,简称为PDCCH)。 [0003] long term evolution (Long-Term Evolution, abbreviated as LTE) version No. 8 (Release 8) defines the following three downlink physical control channel: Downlink Physical control format indicator channel (Physical Control Format IndicatorChannel, abbreviated as PCFICH) , a physical hybrid automatic repeat request indicator channel (physical hybrid AutomaticRetransmission request Indicator channel, abbreviated as PHICH) and a physical downlink Control channel (PhysicalDownlink Control channel, abbreviated as PDCCH). 其中,PDCCH用于承载下行控制信息(Downlink Control Information,简称为DCI),包括:上、下行调度信息,以及上行功率控制信息。 Wherein, the PDCCH carries a downlink control information (Downlink Control Information, referred to as the DCI), comprising: a downlink scheduling information and uplink power control information. DCI的格式(DCI format)分为以下几种:DCI formatO、 DCI format 1、 DCIformat 1A、 DCI format 1B、 DCI format 1C、 DCI format 1D、 DCI format 2、 DCI format2A、 DCI format 3和DCI format 3A等;其中,支持多用户MIMO的传输模式5利用了DCI format ID的下行控制信息,而DCI format ID中的Downlink power offset field是用来显示在多用户MIMO对于一个用户的功率要减半(即-101ogl0(2))的信息,这是因为这个模式只支持两个用户的用户MIMO传输,因为有这个比特,传输模式5可以支持单用户和多用户传输的动态切换,但是无论在单用户或多用户传输这个DCI format都只可以对每个UE支持一个层的传输,虽然LTE Release 8在传输模式4支持最多四个层的单用户传输,但是,因为传输模式之间的切换只能是半静态的,所以要在版本号8做到单用户多层传输和多用户传输的动态切换是不可能的。 DCI format (the format DCI) divided into the following: DCI formatO, DCI format 1, DCIformat 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2, DCI format2A, DCI format 3 and the like DCI format 3A ; wherein the multi-user MIMO transmission mode using 5 downlink control information DCI format ID, and the DCI format downlink power offset field ID is used to display for a multi-user MIMO user to half power (i.e., - information 101ogl0 (2)), it is because the user MIMO transmission mode only supports two users, because of this bit, the transmission mode switching unit 5 can support dynamic and multi-user transmission, but both single-user or multi- the user transmission DCI format may support only one transport layer for each of the UE, although the LTE Release 8 supports up to four transmission mode 4 single-user transmission layer, however, since the switching between the transmission mode can be semi-static , so to do the dynamic switching of single-user and multi-user transmission multilayered transmission version 8 is not possible.

[0046] 在单用户的传输方式,MU比特指示为O,表示这个是单用户传输,eNB要通知UE对该UE传输所用的秩,可以用3个比特来代表秩(nmk), S卩,在单用户传输中所用的秩最大为8。 [0046] In single-user transmission scheme, a MU-bit indication is O, represents the single-user transmission, the eNB to notify the UE of the rank UE used for transmission, may be 3 bits to represent the rank (nmk), S Jie, in single-user transmission used in a maximum of 8 rank.

[0047] 在多用户的传输方式,MU比特指示为1,表示这个是多用户传输,eNB要通知UE对该UE传输所用的秩以及是那一层开始对该UE进行传输,可以用l个比特来代表秩(nmk),即,在多用户传输中所用的秩最大为2,可以用2个比特(Layer Index bit)来通知UE是那一层开始对该UE进行传输,这两个比特在rank bit = 0和rank bit = 1有不同 [0047] In a multi-user transmission scheme, a MU indication bit is 1, this indicates a multi-user transmission, the eNB notifies the UE to the UE a rank used for transmission of the layer is started and the UE for transmission, with a l representative of the rank bits (NMK), i.e., in a multi-user transmission used up to the rank 2, 2 bits may be used (layer Index bit) is used to inform the UE that the UE starts transmitting layer, these two bits in rank bit = 0 rank bit = 1 and different
