Description
Technical field
The present invention relates to the communications field, and in particular to a kind of method and system of control uplink closed loop transmitting diversity.
Background technology
High Speed Uplink Packet access (HSUPA) is the introduced Enhanced Technologies of 3GPP versions (Release, R) 6,
It is intended to improve the transmission rate of up-link, is the enhancing and extension to WCDMA (WCDMA) up-link performance.
HSUPA by introduce fast uplink mix retransmit (HARQ), the uplink scheduling based on node B (Node B) and with version before
Simpler multi-code transmission improves up-link transmission performance, reaches the peak-peak transmission rate of up-link
5.76 million (Mbps) per second.
Multi-antenna technology realizes power system capacity higher, more using many antennas by transmitting terminal and/or receiving terminal
Wide MPS process and better services quality.Many antennas of transmitting terminal and/or receiving terminal both can be used to realize sending
Or reception diversity may also be used for realizing spatial reuse.Wherein, transmitting diversity technology is that one kind contains at least 2 in transmitting terminal transmission
There is the anti-fading technology of the wireless communication field of the signal of identical information.These signals for carrying identical information derive from least 2
Individual separate signal source.The structure of transmitting diversity technical basis its transmission signal sample values and statistical property and its shared nothing
The difference of line resource, can be divided into be combineding with each other for space, frequency, the big fundamental type of time 3, or this 3 type.
Whether transmitting diversity technical basis receiving terminal needs the parameter needed to transmitting terminal feedback diversity to be divided into open loop is launched
Diversity mode and Closed-Loop Transmit Diversity pattern.Under Open-Loop Transmit Diversity pattern, receiving terminal is not any extra to transmitting terminal feedback
The information related to transmitting, transmitting terminal can voluntarily use corresponding coding techniques (such as simple Space-Time is encoded) to complete hair
Penetrate diversity.Under Closed-Loop Transmit Diversity pattern, receiving terminal needs to use feedback channel to feed back to transmitting terminal one and transmitting diversity phase
The parameter (such as the precoding vector needed for transmitting diversity is indicated by precoding configured information) of pass, transmitting terminal is after the receipt
Transmitting diversity is completed using the feedback information.
Reached common understanding in 3gpp meetings at present：Letter is accessed when user equipment (UE) is configured with high-speed link packet
Road, the activation of uplink closed loop transmitting diversity is controlled using high-speed shared control channel command and is deactivated, but if user
