Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of quadrature overlay code configuration and frequency hopping configuration indicating method and device.
Background technology
Introduced the upstream multi-antenna transmission in LTE-A, terminal can utilize a plurality of radio-frequency channels to send data, reaches higher spectrum efficiency.Performance when transmitting for bonding user multilayer transmission and multi-user, minimizing interlayer and inter-user interference can be introduced OCC (Orthogonal Cover Code, quadrature overlay code) and guarantee the orthogonality between interlayer or user.But OCC can only be used for non-time slot frequency-hopping system, if the sub-district has enabled group frequency hopping or sequence hopping, then can not use OCC.In order to make the user in this class sub-district can use OCC, can come each user's of separate configurations group frequency hopping and sequence hopping by the signaling of PDCCH, guarantee orthogonality thereby make full use of OCC.
MIMO (multiple-input and multiple-output) technology all adopts many antennas to send reception at transmitting terminal and receiving terminal, thereby has improved the transmission performance and the capacity of system greatly.In uplink, can realize the MIMO transmission by two kinds of methods: SU-MIMO (single user's multiple-input and multiple-output) and MU-MIMO (multi-user's multiple-input and multiple-output).SU-MIMO utilizes space multiplexing technique, sends a plurality of data flow of certain user on same running time-frequency resource; And MU-MIMO utilizes the orthogonality between the user, sends a plurality of user's data on identical running time-frequency resource.Under the situation that does not increase bandwidth, the MIMO technology can improve capability of communication system and spectrum efficiency exponentially.
In the SU-MIMO transmission, a plurality of data flow occupy identical running time-frequency resource, need to obtain the corresponding up channel of each data flow (the corresponding uplink port of data flow) by DMRS (demodulated reference signal), could detect the data of each stream respectively.The DMRS of different port occupies identical running time-frequency resource, and the orthogonality by the DMRS sequence guarantees that receiving terminal can estimate the channel of each port respectively.In up MU-MIMO transmission, a plurality of users' DMRS has occupied identical resource, also is that the orthogonality by the DMRS sequence guarantees that receiving terminal can detect each user channel separately.
For the SU-MIMO transmission, if the uplink bandwidth is narrower, the DMRS sequence is very short, and is more if send data flow this moment, and then the orthogonality between the DMRS sequence is difficult to guarantee.Similarly, in the MU-MIMO transmission, if multiplexing user's transmission bandwidth difference, then the length of its DMRS sequence is also different, can't guarantee the orthogonality of DMRS sequence.Can introduce the OCC sequence this moment, and two row DMRS sequences of different port multiply by different OCC weightings, thereby guarantee the orthogonality of the DMRS sequence of different port, as shown in Figure 1.
Because UE does not know own residing transmission mode, so the configuration of the weighted value of OCC can only be indicated to UE by signaling by the base station.Under the SU-MIMO pattern, a part of DMRS port of user adopts the OCC weighting (promptly not carrying out the OCC weighting) of [1 1], and another part DMRS port adopts the OCC weighting of [1-1], and then this two parts port can just can utilize OCC to keep orthogonality.If the multiplexing MU-MIMO that carries out of user and other users transmits, then two users can adopt [1 1] and [1-1] that separately DMRS port is weighted respectively, just can utilize the orthogonality of DMRS between OCC assurance user, even two user configured bandwidth differences.Simultaneously, the also not OCC weighting of enables users as required of base station.So, as long as the OCC weighted value of each DMRS port of each user of reasonable disposition just can keep between each DMRS port of certain user or the orthogonality between the DMRS port of different user, no matter the user is SU-MIMO pattern or MU-MIMO pattern.Can have several method to indicate the configuration of OCC at present:
1) with the configuration of OCC and the CS of DMRS (Cycle Shift, cyclic shift) indication binding, do not need extra indication;
2) configuration and RI (Rank Indicator, order indication), the CS with OCC indicates binding, do not need extra indication;
3) indicate the OCC weighted value (two kinds may weighting) of preceding two ports with 1 bit dominance, latter two port predefine;
Simultaneously, organizing frequency hopping and sequence hopping at present is the cell configuration parameter, and each user can not dispose separately, and OCC then can't be used in the sub-district that has therefore enabled this class frequency hopping.
There is following shortcoming in above-mentioned OCC configuration indicating method:
1) scene of Zhi Chiing is limited, is difficult to support the MU-MIMO of high-order, and dispatches limited;
2) some scheme complexity is higher;
3) user is difficult to judge whether to have enabled the OCC function by indication;
Simultaneously, there is not scheme can support the user independently to organize frequency hopping and sequence hopping configuration at present.
