Description

A kind of indication of uplink mode, determine method and system
Technical field
The present invention relates to senior Long Term Evolution (LTE-Advanced abbreviates LTE-A as) system, relate in particular to uplink mode indicating means in this system, determine method and system thereof.
Background technology
At third generation partner program (The 3rd Generation Partnership Project, abbreviate 3GPP as) Long Term Evolution (Long Term Evolution, abbreviate LTE as) in the system, the base station adopts the mode of centralized dispatching to control user terminal (User Equipment, abbreviate UE as) the transmission of Physical Uplink Shared Channel (Physical Uplink Shared Channel abbreviates PUSCH as).
The base station sends to object UE by Physical Downlink Control Channel (Physical Downlink Control Channel abbreviates PDCCH as) with the uplink scheduling information (uplink scheduling information) of PUSCH.Physical Downlink Control Channel bearing downlink control information (Downlink Control Information, abbreviate DCI as), comprising following/uplink scheduling information (downlink or uplink scheduling information), uplink transmission power control command etc.According to different Downlink Control Information, LTE system definition multiple descending control information format (DCI format).The uplink scheduling information of PUSCH is carried in the descending control information format 0 (DCI format 0).If UE detects the PDCCH with DCI format0 form,, on the channel resource that is distributed, adopt indicated modulation coding mode and corresponding transmission power to send PUSCH then according to the uplink scheduling information that wherein comprises.
Wherein, comprise following information among the DCI format 0: the flag bit that is used to distinguish DCI format 0 and DCI format1A; The frequency hopping flag bit; Resource block assignments and frequency-hopping resource distribute; Modulation coding mode (Modulation and Coding Scheme abbreviates MCS as) and redundancy versions (Redundancy Version abbreviates RV as); New data indication (New data indicator); The emissive power control command (TPC command for scheduled PUSCH) that is used for the PUSCH that dispatched; The cyclic shift of demodulated reference signal (Cyclic shift for DM RS); Up indication (UL index) exists only in time division duplex (Time Division Duplex abbreviates TDD as) system, and being used for uplink-downlink configuration (Uplink-downlinkconfiguration) is 0 o'clock; Descending distribution indication (Downlink Assignment Index abbreviates DAI as) exists only in tdd systems, and being used for uplink-downlink configuration is 1～6 o'clock; Channel quality indication request (CQI request).
In the LTE system, the PUSCH frequency division multiplexing up-link bandwidth of a plurality of UE in the sub-district, promptly the PUSCH of different UEs is quadrature on frequency domain.And the base station is designated as the radio channel resource of the PUSCH of object UE distribution in DCI format 0.
In the LTE system, PUSCH adopts the single antenna port transmission.In the LTE system, the modulation coding mode of PUSCH and redundancy versions be joint instructions in DCI format 0, and wherein, the joint instructions bit is 5 bits.
The LTE-A system is the evolution system of future generation of LTE system.Introduced carrier aggregation technology (carrier aggregation) in this system, the carrier wave of each polymerization is called one " component carrier " (component carrier).A plurality of component carriers can be continuous, also can be discontinuous, can be positioned at same frequency range (frequency band), also can be positioned at different frequency range.
In the LTE-A system, PUSCH can adopt the single antenna port transmission, also can adopt many antenna port transmission.When many antenna ports transmit, LTE-A supports based on one or two code word (Codeword, abbreviate CW as) spatial reuse, the corresponding transmission block TB of each code word, corresponding modulation coding mode (5 bit) of each transmission block and new data are indicated (1 bit).Subscriber equipment is set to a kind of uplink transmission mode (Uplink transmission mode) by high-level signaling semi-static (semi-statically), on corresponding search volume, monitoring descending control signaling then, obtaining transmission means on the corresponding PUSCH by this descending control signaling.
LTE-A adopts based on code book (codebook, be called code book again) linear predictive coding technology (precoding), that is, transmitting terminal utilizes channel condition information (Channel Status Information, abbreviate CSI as), carry out preliminary treatment (precoding) to transmitting.A kind of approach that transmitting terminal obtains CSI is the feedback by receiving terminal.In order to reduce feedback overhead, the general mode that adopts is to preserve identical code book, i.e. pre-coding matrix collection at receiving terminal with transmitting terminal.Receiving terminal is according to current channel conditions, in code book, select suitable pre-coding matrix, and with its pre-coding matrix index value (Precoding Matrix Index in code book, abbreviate PMI as) feed back to transmitting terminal, transmitting terminal finds corresponding pre-coding matrix according to the pre-coding matrix index value of feedback, carries out precoding to sending signal.In the LTE-A system, the precoding information of PUSCH also should be indicated at the descending control information format that is used for uplink scheduling.
In the LTE-A up link, the base station is according to current channel conditions, selects suitable pre-coding matrix in code book, and with its PMI in code book together with some other uplink scheduling information, be carried in certain descending control information format, send to the UE that is dispatched through PDCCH.UE finds pre-coding matrix according to the PMI in the detected descending control information format, carries out precoding to sending signal.
At present, the code book in the LTE-A system has designed and has finished, and still, the scheme that is used to carry the descending control information format of uplink scheduling information does not also have final determining.Comprise the descending control signaling that is used to indicate the up link precoding information in existing descending control information format, the different values of the control domain of this descending control signaling (also can be described as different conditions) are used to indicate different pre-coding matrixes.When UE sent upstream data, the pre-coding matrix of indicating according to this descending control signaling carried out precoding.But the base station can not be by the information of this descending control signaling to UE indication uplink mode.Correspondingly, UE can not determine whether adopting the transmission means of Open-Loop Spatial Multiplexing according to the indication of base station, thereby makes troubles to uplink scheduling.When adopting Open-Loop Spatial Multiplexing, UE also needs to determine whether to reach how to carry out precoding when uplink, also do not relate in the prior art at present.
