Running time-frequency resource can be represented with frequency domain information and time-domain information.In the embodiment shown in fig. 3, may be used Running time-frequency resource is represented with RBG mark and time domain unit offset amount, each running time-frequency resource occupies one RBG, and a time domain unit is occupied in time domain, such as 1 subframe or 1 TTI.One RBG It may include multiple RB, for example, W RB.By taking Fig. 3 as an example, (RBG1,0) can be used to represent frequency domain For RBG1, time domain is T0 running time-frequency resource；Can be RBG1 with (RBG1,4) expression frequency domain, when Domain is T4 running time-frequency resource.Alternatively, the time domain unit can also represent by time domain unit is the cycle, Such as using 4 TTI as the cycle, for example, available (RBG1,0) table in T0-T3 period 1 It is RBG1 to show frequency domain, and time domain is T0 running time-frequency resource, and can use (RBG1,0) T4-T7's It is RBG1 that frequency domain is represented in second round, and time domain is T4 running time-frequency resource.

The network equipment can be divided further to the set of universal reference signal port, and the generalized reference is believed Number antenna port set is divided into N number of mutually disjoint antenna port set, and this is N number of mutually disjoint Antenna port set alternatively includes identical antenna port number.

The network equipment may further be antenna port set corresponding to each time-frequency resource allocating, for example, will N number of continuous or discrete running time-frequency resource of same frequency resource respectively with N number of mutually disjoint day The set of line end mouth corresponds, or N number of continuous or discrete frequency domain resource point of identical time-domain resource Do not corresponded with N number of mutually disjoint antenna port set.It should be understood, of course, that this is simply a kind of Preferable scheme, in the application of reality, there may be different configuration modes.Such as, it is only necessary to ensure Antenna port set corresponding to frequency domain two running time-frequency resources of adjacent time domain identical is different, the adjacent frequency domain of time domain Antenna port set difference, etc. corresponding to two running time-frequency resources of identical.

It should be understood that each running time-frequency resource corresponds to an antenna port set, the network equipment can be in the time-frequency Antenna port in resource and corresponding antenna port set sends reference signal.It should be understood that the general ginseng Examine between the division of signal antenna port set, and antenna port set after running time-frequency resource and division Corresponding relation, can be prespecified by network equipments configuration, or by standard agreement.With reference to Fig. 3, Illustrated by taking network equipments configuration as an example.

It might as well assume that universal reference signal port set (32 Beam directions) is divided into 4 by the network equipment Group (i.e. 4 mutually disjoint antenna port sets 1), every group of 8 Beam directions, i.e. 8 antennas Port (or claiming RS port).First group：Beam#0/4/8/12/16/20/24/28；Second group：Beam #1/5/9/13/17/21/25/29；3rd group：Beam#2/6/10/14/18/22/26/30；4th group：Beam #3/7/11/15/19/23/27/31.First group of Beam direction can be such as the Beam directions of tape label in Fig. 2 It is shown.It should be understood, of course, that the antenna port of each RBG distribution can also be other numerical value, example Such as, 4 antenna ports, 6 antenna ports, etc..

A kind of configuration running time-frequency resource and the possible configuration mode of antenna port set are as follows：

Citing ground, based on the above-mentioned dividing mode that 32 Beam directions are divided into 4 groups, the network equipment It can be to occupy identical frequency domain resource on frequency domain, continuous 4 time domain units (TTI) are occupied in time domain 4 running time-frequency resources one group of Beam direction is respectively configured.For example, in Fig. 3, frequency domain RBG1, Time domain is in T0-T3 4 running time-frequency resources, and identical frequency domain resource is occupied on frequency domain, is occupied in time domain Continuous 4 time domain units (TTI), and each running time-frequency resource corresponds respectively to one group of antenna port. That is in a time cycle, (in embodiment illustrated in fig. 3, a time cycle includes 4 time domains Unit), 4 running time-frequency resources of same frequency resource respectively with after the set division of universal reference signal port 4 antenna port sets correspond.Specifically, for RBG1, the T0 moment configures One group of Beam direction, T1 moment configure the 4th Beam direction, and the T2 moment configures the 3rd group of Beam Direction, T3 moment configure second group of Beam direction, and the T5 moment configures first group of Beam direction ..., Analogize circulation as the cycle using this 4 TTI to go down, just complete poll on frequency domain and configure each running time-frequency resource pair The antenna port for the transmission universal reference signal answered.

Citing ground, based on the above-mentioned dividing mode that 32 Beam directions are divided into 4 groups, the network equipment Can be that one group of Beam side is respectively configured in N number of running time-frequency resource configuration that frequency domain is adjacent in same time domain unit To so that the adjacent N number of running time-frequency resource of frequency domain and the universal reference signal port collection in same time domain unit N number of antenna port set after division is closed to correspond.For example, in the embodiment shown in fig. 3, time domain The day configured for T0, frequency domain by RBG1, RBG2, RBG3 and RBG4 four running time-frequency resources The set of line end mouth corresponds.Specifically, the T0 moment, first group of Beam direction is configured on RBG1, Configure second group of Beam direction on RBG2, configure the 3rd group of Beam direction on RBG3, on RBG4 Configure the 4th group of Beam direction.Analogize circulation as the cycle using this 4 RBG to go down, just complete time domain Upper poll configures the antenna port that universal reference signal is sent corresponding to each running time-frequency resource.

Fig. 4 gives the pattern of a running time-frequency resource reference signal.Fig. 4 is using a RBG as frequency domain list , exemplified by the running time-frequency resource that a TTI is formed for time domain unit, certain those skilled in the art can A running time-frequency resource can also be formed in units of other time domains or frequency domain to know.Wherein, it is every in Fig. 4 Individual grid can represent a RE or other time/frequency source blocks, here by taking RE as an example.It is white in Fig. 4 Color does not have the RE of digital grid to represent to can be used for sending data, and the RE for having digital grid is represented can be with Such as include universal reference signal for sending reference signal, including white has the RE and ash of digital grid Color has the RE of digital grid, digitized representation antenna port sequence number.The RE of wherein grey grid represents quilt Using for sending reference signal.Fig. 4 example is properly termed as reference signal pattern, can be used for this hair The reference signal money of running time-frequency resource of the bright embodiment including the first running time-frequency resource and the second running time-frequency resource Source configures, including is used to send the RE of reference signal in the running time-frequency resource and joins for being sent in the RE Examine the antenna port of signal.

The present invention is further illustrated with reference to the interaction flow of reference signal transmission of the embodiment of the present invention The scheme of embodiment.
