Abstract

The invention discloses indicating method and device of a transmission mode, wherein the method comprises the following step of increasing indicating information in a descending control information format, wherein the indicating information is used for indicating control information for supporting the transmission mode of user equipment. The invention achieves the support of MIMO multiuser transmission on the basis of demodulation pilot-frequency.

Description

The indicating means of transmission means and device
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 radio communication, if use many antennas at transmitting terminal (eNB), we can take the mode of spatial reuse to improve transmission rate, the different data of the i.e. emission of different antennae position on the identical running time-frequency resource of transmitting terminal, (UE) also uses many antennas at receiving terminal, we can distribute to same user with the resource of all antennas under single user's situation, this transmission form is called SU-MIMO (Single User MIMO), we also can give different user with the resource allocation in different antennae space under multi-user's situation in addition, and this transmission form is called MU-MIMO (multiuser MIMO).Transmission system is if support Single User MIMO and multiuser MIMO at the same time, eNB is necessary to be provided at data under these two kinds of transmission modes with controlling signaling to UE.UE needs to know that in these two kinds of transmission modes eNB is for the used order (Rank) of this UE transmission, under single user mode, because the resource of all antennas is all distributed to same user, transmit the used number of plies and just equal eNB in the used order of this transmission, and in multi-user's transmission, it is the total number of plies that is less than this transmission that corresponding user is transmitted the used number of plies.Accomplish the dynamic switching of single user and multi-user transmission, eNB need be in the different transmission mode different data of UE that sends a notice.
Long Term Evolution (Long-Term Evolution, abbreviate LTE as) version number 8 (Release 8) in defined following three kinds of downlink physical control channels: physical down control format indicating channel (Physical Control Format Indicator Channel, abbreviate PCFICH as), the automatic repeat requests indicating channel of physical mixed (Physical HybridAutomatic Retransmission Request Indicator Channel, abbreviate PHICH as) and Physical Downlink Control Channel (Physical Downlink Control Channel abbreviates PDCCH as).PDCCH wherein is used for bearing downlink control information (Downlink ControlInformation abbreviates DCI as), comprising: uplink and downlink schedule information, and uplink power control information.The form of DCI (DCI format) 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 the transmission mode 5 of multiuser MIMO to utilize the Downlink Control Information of DCIformat 1D, and the Downlink poweroffset field δ among the DCI format 1D Power-offsetBe to be used for being presented at multiuser MIMO for will the reduce by half information of (promptly-10log10 (2)) of a user's power, this is because this pattern is only supported two users' user MIMO transmission, because this bit is arranged, transmission mode 5 can be supported the dynamic switching of single user and multi-user's transmission, but transmit this DCI format all only each UE is supported the transmission of a stream single user or multi-user, though LTERelease 8 supports single user's transmission of maximum two streams in transmission mode 4, but because the switching between the transmission mode can only be semi-static, so to accomplish that the dynamic switching of single user's multithread transmission and multi-user's transmission is impossible in version number 8.
In addition, in the version number 10 of LTE, the transmission mode of MIMO has been determined to separate the pilot tone of calling with demodulation pilot frequency (Demodulation Reference Signal abbreviates DMRS as), UE will obtain the position of pilot tone, just can do the estimation of channel and interference on pilot tone.Total number of plies of different transmission has different pilot frequency designs, for example in the version number 10 of LTE, three kinds of different patterns (DMRS Pattern) have tentatively been decided to have, total number of plies of transmission or order are time 1 to 2, with first pattern (DMRS pattern 1), total number of plies of transmission or order are time second pattern of standby (DMRS pattern 2) of 3 to 4, total number of plies of transmission or order are 5 to 8 time the 3rd pattern of standby (DMRS pattern 3). in single user's transmission, the data of all transport layers all are to same UE, as long as just can know pilot frequency design so UE obtains order, also can know the position of pilot tone. in multi-user's transmission, UE will know that one deck of sum of ranks begins this UE is transmitted, UE will know that also the pilot frequency design of transmission usefulness just can obtain the pilot frequency locations of interference. in the technology of existing version number 8, do not have same requirement, so the version number 10 of LTE wants a new signaling to go to support the MIMO multi-user based on DMRS to transmit.
For SU-MIMO, promptly single user's transmission means is meant that a subscriber equipment occupies the physical resource of distributing to described subscriber equipment alone in a transmission intercal.For MU-MIMO, promptly multi-user's transmission means is meant a subscriber equipment and at least one other subscriber equipment shared physical resource of distributing to described subscriber equipment in a transmission intercal.A subscriber equipment and other subscriber equipment are shared same physical resource by space division multiple access or space division multiplexing mode.This physical resource can be a running time-frequency resource.
