Description
Technical field
The present invention relates to the scheduling scheme in wireless communication system, particularly relate to based on Long Term Evolution
(LTE-Long Term Evolution) for multi-user's superposition (Superposition)
The method and apparatus of control signaling.
Background technology
Traditional 3GPP (3rd Generation Partner Project, third generation affiliate
Project) in cellular system, the downstream wireless signals of multi-user is by { TDM (Time Division
Multiplexing, time division multiplex), FDM (Frequency Division Multiplexing,
Frequency division multiplexing), CDM (Code Division Multiplexing, code division multiplexing) in one
Plant or various ways realizes.3GPP R (Release, version) 13 introduces one newly
Research topic (RP-150496)-descending multi-user superposition, i.e. utilize the difference of transmit power
Distinguish the downstream wireless signals of two users.Said two user generally includes a nearly user (i.e.
Distance base station is near) and remote user (i.e. remote apart from base station), base station is for nearly user
The transmit power that one signal distribution is relatively low, is that the secondary signal for remote user is distributed higher simultaneously
Transmit power.Remote user directly demodulates secondary signal (will the first signal work as noise processed), and
First nearly user demodulates secondary signal (possesses lower path in view of nearly user user farther out to damage
Consumption, successfully decoded probability is the highest), then from receiving the impact removing secondary signal signal
Obtain residual signal, residual signal decoding is obtained the first signal, here it is SIC (Successive
Interference Cancellation, successive interference cancellation) algorithm.In order to perform SIC, closely
User needs to obtain the first signal and the schedule information-of secondary signal and remote user has only to obtain the
The schedule information of binary signal.
It should be noted that the specific implementation of above-mentioned SIC algorithm is by UE (User
Equipment, subscriber equipment) manufacturer determines voluntarily.And as the replacement of a kind of SIC or benefit
Filling scheme, nearly UE (or remote UE) can use IRC (Interference Rejection
Combining, AF panel merges) algorithm carries out whitening operation to the wireless signal of superposition, with
Improve receptivity.IRC algorithm does not require that UE correct decoding disturbs wireless signal, it is only necessary to estimate
The channel parameter of interference wireless signal.
In traditional LTE dynamic dispatching, user is according at PDCCH (Physical Downlink
Control Channel, Physical Downlink Control Channel) or EPDCCH (Enhanced PDCCH,
Strengthen PDCCH) in transmission DCI (Downlink Control Information, descending
Control information) (Physical Downlink Shared Channel, under physics to obtain PDSCH
Row control channel) schedule information.For a kind of DCI payload size (Payload Size),
UE performs BD (Blind Decoding, blind decoding) to determine corresponding PDCCH or EPDCCH.
Therefore, BD the number that UE at most performs along with required for UE the DCI payload size number of monitoring and increase
Adding, in order to reduce the increase of the UE complexity that BD time too much number causes, base station is believed by high level
Make and configure TM (Transmission Mode, transmission mode) for UE, for each TM, UE
Only need to detect two kinds of DCI payload size.
For multi-user's superposition, one intuitively idea be that base station is (for nearly user) first
Increasing extra bit in the scheduling DCI of signal, described extra bit is for carrying and the second letter
Number relevant information.
