Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of transmission and processing method, system and equipment of channel quality indication masking instruction.
Background technology
In Long Term Evolution (LTE) system, (Radio Resource Control RRC) can have continuous reception and discontinuous reception (Discontinuous Receiption, DRX) two states to terminal (UE) under the connection status in the Radio Resource control.DRX refers to discontinuous reception descending scheduling of terminal and downlink data, and when not needing to receive downlink transfer, terminal can be in dormancy (sleep) state, to reach purpose of power saving.
DRX carries out the periodicity configuration, and each DRX cycle is introduced into an of short duration continuous accepting state when beginning, and is called and monitors the period (on duration), and its duration is determined by On Duration Timer.The definition of On Duration Timer is: continuous severally can carry Physical Downlink Control Channel (Physical Downlink Control Channel, subframe PDCCH) from what the DRX cycle starting point began to count.UE need monitor PDCCH during this period, to check the resource allocation that whether has at this UE.If terminal receives descending scheduling and downlink data during on duration, to start other timers and carry out follow-up scheduling process, if but terminal does not receive descending scheduling and downlink data during on duration, will enter dormancy (sleep) state, up to next DRX cycle, On Duration Timer could receive downlink transfer when starting again.The periodicity configuration of DRX as shown in Figure 1.
If UE receives descending scheduling and downlink transfer during on duration, also may start following timer, UE further monitors PDCCH with indication:
The non-Active Timer of DRX (DRX Inactivity Timer): start when receiving the PDCCH that dispatches new data, UE monitors PDCCH always between the starting period; End condition is this timer expiry or the medium access control (MAC) of receiving forced termination layer signaling.
Mix automatic request retransmission timer two-way time (HARQ Round Trip Time Timer, HARQRTT Timer): at downlink transfer.Start when receiving the PDCCH of dispatching downlink data, regular length is a retransmission time interval, unless covered by other timers during this period, otherwise need not monitor PDCCH;
DRX retransmission timer (DRX Retransmission Timer): at downlink transfer.The overtime back of HARQ RTTTimer starts, and UE monitors PDCCH always between the starting period; End condition is this timer expiry or receives the retransfer scheduling of expectation.
Competition solves timer (Contention Resolution Timer): a timer in the random access procedure.The uplink by the accidental access response scheduling that sends random access procedure from UE begins to start, and UE monitors PDCCH always between the starting period; End condition is this timer expiry or successfully receives competition solution message.
Activationary time (active time) is relevant DRX operation, and the subframe that need monitor PDCCH at UE all belongs to active time.Referring to Fig. 2, be that a UE receives the example that DRX inactivitytimer prolongation active time is opened in scheduling.The subframe that UE receives on duration is received the PDCCH scheduling, thereby at this moment UE can open DRX inactivity timer prolongation active time.DRXRetransmission Timer and Contention Resolution Timer may prolong the activetime of UE equally.
(channel quality indicator CQI), is the parameter that is used for characterizing channel quality in the channel quality indication.Can understand quality of channel by the CQI base station, UE is reasonably dispatched.CQI can dispose in the cycle in LTE, also can dynamic dispatching.Adopt RRC signaling configuration cycle CQI, adopt PDCCH signaling dynamic dispatching CQI.
In the version of LTE R8, when UE has disposed the CQI in cycle, and UE disposed the DRX operation and the time will require UE to send CQI at activationary time, as shown in Figure 3.
In the R9 version, introduced CQI and sent shielding (CQI-mask) signaling, when disposed then UE transmission cycle CQI during on duration only of CQI-mask signaling for UE.As shown in Figure 4, because on duration is fairly regular, the base station can be given other UE cycle CQI resource-sharing easily.
In LTE and the wireless communication system in the past, have only (or a pair of) carrier wave usually in each sub-district, the UE synchronization can only (on the carrier wave) carry out data transmit-receive in a sub-district.The maximum bandwidth of carrier wave is 20MHz in the LTE system, as shown in Figure 5.
Long-term evolution upgrading (LTE Advanced, LTE-A) in the system, the peak rate of system improves a lot than LTE, require to reach descending 1Gbps, up 500Mbps, the transmission bandwidth of 20MHz can't satisfy this demand.For higher transmission rate is provided, the LTE-A system has adopted carrier aggregation technology, i.e. UE a plurality of member carriers of polymerization and on these carrier waves, carry out transfer of data simultaneously simultaneously, thus improve message transmission rate.For the UE that guarantees LTE can work under the carrier wave of each polymerization, each carrier wave maximum is no more than 20MHz.
The CA technology as shown in Figure 6 in the LTE-A system.In LTE-A system shown in Figure 6, the polymerisable carrier wave number of UE is 4, and network side can carry out transfer of data with UE simultaneously on 4 carrier waves.
In realizing process of the present invention, the inventor finds to exist in the prior art following technical problem:
Introduce the CA technology in the LTE-A system after, UE is operated under the situation of multicarrier, and how carry out CQI-mask this moment does not also have concrete implementation.
