Abstract
The invention discloses a kind of indicating means and device of transmission means, the method comprises: in descending control information format, increase indication information, and wherein, indication information is used to indicate the control information of the transmission means supporting subscriber equipment.Present invention achieves the MIMO multi-user transmission supported based on demodulation pilot frequency.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of indicating means and device of transmission means.
Background technology
In wireless communications, if use many antennas at transmitting terminal (eNB), we can take the mode of spatial reuse to improve transmission rate, namely different data are launched in the different antennae position on the running time-frequency resource that transmitting terminal is identical, also many antennas are used at receiving terminal (UE), the resource of all antennas can all be distributed to same user when single user by us, this transmission form is called SU-MIMO (Single User MIMO), in addition we also can when multi-user by the Resourse Distribute in different antennae space to different user, this transmission form is called MU-MIMO (multiuser MIMO).If transmission system will at the same time between support Single User MIMO and multiuser MIMO, eNB is the data being necessary to be provided in UE with control signal under these two kinds of transmission modes.UE needs to know that eNB transmits order (Rank) used for this UE in these two kinds of transmission modes, in the single-user mode, because the resource of all antennas all distributes to same user, transmit the number of plies used and just equal eNB in this transmission order used, and in multi-user transmission, it is the total number of plies being less than this transmission that a corresponding user transmits the number of plies used.Accomplish the switching at runtime of single user and multi-user transmission, eNB needs to send a notice the different data of UE at different transmission mode.
Long Term Evolution (Long-Term Evolution, referred to as LTE) version number 8 (Release 8) in define following three kinds of downlink physical control channels: physical down control format indicating channel (Physical Control Format Indicator Channel, referred to as PCFICH), physical hybrid automatic repeat request indicator channel (Physical HybridAutomatic Retransmission Request Indicator Channel, referred to as PHICH) and Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH).PDCCH is wherein used for bearing downlink control information (Downlink ControlInformation, referred to as DCI), comprising: uplink and downlink schedule information, and uplink power control information.The form (DCI format) of DCI is divided into following several: DCI format0, DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2, DCI format 2A, DCI format 3 and DCIformat 3A etc., wherein support that the transmission mode 5 of multiuser MIMO make use of the Downlink Control Information of DCIformat 1D, and the Downlink poweroffset field δ in DCI format 1D
power-offsetbe used to be presented at multiuser MIMO will to reduce by half for the power of a user information of (i.e.-10log10 (2)), this is because this pattern only supports user's MIMO transmission of two users, because there is this bit, transmission mode 5 can support the switching at runtime of single user and multi-user transmission, but at single user or this DCI format of multi-user transmission all only to support a transmission of flowing to each UE, although LTERelease 8 supports the single user transmission of maximum two streams in transmission mode 4, but because the switching between transmission mode can only be semi-static, so will accomplish that the switching at runtime of single user multiple stream transmission and multi-user transmission is impossible in version number 8.
In addition, in the version number 10 of LTE, the transmission mode of MIMO has determined uses demodulation pilot frequency (Demodulation Reference Signal, referred to as DMRS) to carry out the pilot tone called as solution, UE will obtain the position of pilot tone, just can do the estimation of channel and interference in pilot tone.Total number of plies of different transmission has different pilot frequency designs, such as in the version number 10 of LTE, tentatively determine to have the pattern (DMRS Pattern) that three kinds different, time total number of plies of transmission or order are 1 to 2, with first pattern (DMRS pattern 1), total number of plies of transmission or order be 3 to 4 time standby second pattern (DMRS pattern 2), total number of plies of transmission or order are time standby the 3rd pattern (DMRS pattern 3) of 5 to 8.In single user transmission, the data of all transport layers are all to same UE, as long as so UE obtains order just can know pilot frequency design, also can know the position of pilot tone.In multi-user transmission, UE will know that one deck of sum of ranks starts to transmit this UE, and UE also will know that the pilot frequency design of transmission just can obtain the pilot frequency locations of interference.In the technology of existing version number 8, not same requirement, so the version number 10 of LTE wants a new signaling to go to support the MIMO multi-user transmission based on DMRS.
For SU-MIMO, i.e. single user transmission means, refers to that a subscriber equipment occupies alone the physical resource distributing to described subscriber equipment in a transmission intercal.For MU-MIMO, i.e. multi-user transmission mode, refers to that the physical resource distributing to described subscriber equipment shared by a subscriber equipment and at least one other subscriber equipment in a transmission intercal.A subscriber equipment and other subscriber equipment share Same Physical resource by space division multiple access or space division multiplexing mode.This physical resource can be running time-frequency resource.
