Description

Determination method and device, base station, the terminal of PHICH resource
Technical field
The present invention relates to communication technical field, determination method and device, base in particular to a kind of PHICH resource Stand, terminal.
Background technology
The uplink physical channel of long evolving system (LTE, Long Term Evolution) system connects comprising physical accidental Enter channel (PRACH, Physical Random Access Channel), Physical Shared Channel (PUSCH, Physical Uplink shared channel), Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel).For PUSCH uplink scheduling information (Uplink Scheduling Information), thing is passed through by base station Reason down control channel (PDCCH, Physical Downlink Control Channel) is sent to target UE.Uplink scheduling Information includes：Physical Uplink Shared Channel related resource allocation, modulation and encoding scheme, DMRS cyclic shift (Cyclic The control information such as Shift).
Physical Uplink Shared Channel uses single antenna port transmission in LTE system.One system-frame (frame) includes 10 Subframe (subframe), each subframe include 2 time slots (slot).Fig. 1 is the routine in a time slot according to correlation technique The schematic diagram of cyclic prefix, as shown in figure 1, for conventional cyclic prefix (Normal CP, Normal Cyclic Prefix), Each time slot is made up of 6 data symbols and 1 demodulated reference signal.Fig. 2 is in a time slot according to correlation technique The schematic diagram of extended cyclic prefix, for extended cyclic prefix (Extended CP, Extended Cyclic Prefix), often Individual time slot is made up of 5 data symbols and 1 demodulated reference signal.
By a Sequence composition on frequency domain, the sequence is one of reference signal sequence and followed demodulated reference signal DM RS Ring shifts.In order to be randomized inter-cell interference, the reference signal sequence of demodulated reference signal configures according to base station, it is possible to achieve base (Sequence hopping) is redirected in the sequence of time slot or sequence group redirects (Group hopping), when this mode is also known as The SGH modes that gap redirects.That is, configured according to base station, demodulation reference of the user equipment in a subframe on two time slots Signal is different, is changed according to certain pattern that redirects in a system-frame with time slot.
In time slot nsIn, the cyclic shift amount α of demodulated reference signalλFor：Wherein,In a radio frames, ns=0,1 ..., 19；By higher level parameters Configuration,Configured by uplink scheduling information, referred to as up DMRS cyclic shifts.nPN(ns) generated by pseudo-random generator, It is with time slot nsThe parameter of change, is embodied asPseudo random sequence generator is every Once, primary condition is for individual radio frames initializationInitialization value with it is affiliated Cell ID is relevant, is the proprietary parameter of cell.Wherein,For cell ID, △ssFor the parameter of high level configuration.
Uplink scheduling information is carried on Physical Downlink Control Channel, with certain descending control information format (DCI Format, Downlink Control Information format) target UE is sent to by base station.In LTE system In, descending control information format is divided into following several：DCI format 0,1,1A, 1B, 1C, 1D, 2,2A, 3,3A etc., wherein, DCI format 0 include uplink scheduling information, for indicating Physical Uplink Shared Channel PUSCH scheduling.
LTE-Advanced systems (abbreviation lte-a system) are the evolution systems of future generation of LTE system.In lte-a system, When Physical Uplink Shared Channel is transmitted using multi-antenna port, the DMRS of each layer data is equally prelisted with each layer data Code.And the demodulated reference signal of different layer datas, including single user multi-input multi-output system (SU-MIMO) same user is set The demodulated reference signal of standby multi-layer data, and multiuser mimo system (MU-MIMO) multiple user equipmenies are more The demodulated reference signal of layer data, by using different demodulated reference signal cyclic shifts (CS) and/or orthogonal mask (OCC, Orthogonal Cover Code) it is orthogonalized, to distinguish the different layer datas of user's space multiplexing or distinguish different User.Wherein, orthogonal mask OCC is [+1 ,+1] and [+1, -1], acts on two time slots in a subframe (Subframe) (Slot) demodulated reference signal on.User is matched for the MU of different-bandwidth, OCC can only be used to carry out just different users Friendshipization, therefore, the MU pairings number of users maximum of support are only 2.
At present, in the Standard Edition that 3GPP is formulated, the version of LTE standard is the 8th edition (Release 8) and the 9th edition (Release 9), the version of LTE-A standards is the 10th edition (Release 10), is abbreviated as Rel-8, Rel-9 and Rel- respectively 10, LTE-A standards may also include later release, such as Rel-11/12/13/14.At present in Rel-10 versions, base station can be with By DCI format 0 and DCI format 4 come indicate the cyclic shift of the demodulated reference signal for scheduled PUSCH/ OCC information, as shown in table 1.
Table 1
Table 1 is up associated DC I format cyclic shift region[w(λ)(0) w(λ)(1)] mapping table,For the value of up DMRS cyclic shifts, descending control signaling dynamic instruction is up when corresponding upstream space is multiplexed The cyclic shift value of each layers of DMRS, λ are the index of layer, when using orthogonal mask OCC to demodulated reference signal orthogonalization, base station Need to carry out joint-detection to the demodulated reference signal in a subframe on two time slots, thus require a user equipment one Demodulated reference signal in individual subframe on two time slots must be the same.In this case, it is impossible to use time slot in LTE system The SGH modes redirected.But in order to be randomized inter-cell interference as far as possible, the SGH modes that subframe redirects are proposed in correlation technique. That is, configured according to base station, demodulated reference signal of the user equipment in a subframe on two time slots is the same, one Demodulated reference signal in individual system-frame in each subframe is different, and pattern is redirected in a system-frame according to certain Change with subframe.
