Description
Technical field
The present invention relates to the transmission diversity technique field of multiple antennas, more particularly to a kind of up diversity capability reporting that sends
Method and terminal.
Background technology
Multi-antenna technology using more antennas in transmitting terminal and/or receiving terminal by realizing higher power system capacity, more
Wide MPS process and better services quality.Transmitting terminal and/more antennas of receiving terminal can both be used for realizing transmission or
Diversity is received, may also be used for realizing spatial reuse.Wherein, it is that one kind contains in transmitting terminal transmission at least two to send diversity technique
There is the anti-fading technology of the wireless communication field of the signal of identical information.The signal of these carrying identical informations derives from least two
Individual separate signal source.Send structure and statistical property and its shared nothing of the diversity technique according to its transmission signal sample value
The difference of line resource, the mutual of space, frequency, this three big fundamental type of time or these three types can be divided into
With reference to.So-called space diversity refers to, using the difference of different launch sites (space) position, signal reaches after channel is undergone to be connect
Irrelevance during receiving end in statistical property, realize anti-fading function.So-called frequency diversity refers to, using positioned at different frequencies
Uncorrelated characteristic of the signal of section after fading channel statistically, i.e. difference on different frequency range fading statistical characteristics, come real
The function of existing anti-fading (frequency selectivity).Information to be sent can be modulated to the incoherent carrier wave of frequency respectively when realizing
On launched.So-called time diversity refers to, using a randomly fading signal, when the time interval of sample point is sufficiently large
(being more than transmission channel coherence time), the decline between sampling point are statistically orthogonal, that is, utilize time fading rise statistics
Difference in characteristic realizes anti-time selective fading.
Send whether diversity technique needs to be divided into open loop transmission to the parameter that transmitting terminal feedback diversity needs according to receiving terminal
Diversity mode and closed-loop diversity transmitting module.Open loop is sent under diversity mode, and receiving terminal is not any extra to transmitting terminal feedback
Launch related information, transmitting terminal can voluntarily use corresponding coding techniques (such as simple Space-Time coding) to complete to send
Diversity.Under closed-loop diversity transmitting mode, it is related to sending diversity that receiving terminal needs to use feedback channel to feed back to transmitting terminal one
Parameter (such as send diversity needed for precoding vector, indicated by precoding configured information), transmitting terminal makes after the receipt
Completed to send diversity with the feedback information.
In 3GPP Release 10, High Speed Uplink Packet access (HSUPA, High Speed Uplink
Packet Access) the up open loop of system subscriber terminal sends diversity and has been completed the formulation (TR25.863) of standard, at present
The related content of closed-loop diversity transmitting is being discussed, is introducing precoding control instruction (PCI, Precoding Control
Indication).Industry is reached common understanding in the channel architecture of uplink closed loop transmission diversity at present, as shown in figure 1, in increase by one
Row channel, i.e., auxiliary Dedicated Physical Control Channel (S-DPCCH, Secondary-Dedicated Physical Control
Channel), the auxiliary pilot value received and Dedicated Physical Control Channel can be utilized to network side, network side by uploading auxiliary pilot value
Pilot value in (DPCCH, Dedicated Physical Control Channel) understands the weak situation of channel path；Newly
Increase a down channel, channel (F- is indicated similar to fractional dedicated physical channel (F-DPCH), i.e. fraction precoding
PCICH), for transmit up transmitting diversity precoding values to terminal, more preferably prevent the weak situation in path to reach.Mesh
Before, it is that 3 time slots are sent once for F-DPCH, during for there is compact model transmission, terminal preserves last before interval
The individual PCI received, receives new precoding behind compressed mode transmission interval.
Up open loop sends diversity and is adapted for use with the relatively low scene of some terminal rate travels, higher for rate travel
Scene be less applicable because easily causing Doppler effect, current industry reaches following common recognition：Terminal reports open loop to send out
