Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to the methods, devices and systems of a kind of transmission SRS (SoundingReference Symbols, channel detection reference symbol).
Background technology
SRS is LTE (Long Term Evolution, Long Term Evolution) a kind of uplink detection reference symbol of system's introducing, the base station is by receiving the SRS that UE sends, can estimate UE (User Equipment, subscriber equipment) uplink signal-channel quality, and UE is carried out rational management according to the uplink signal-channel quality of UE.At TDD (Time Division Duplex, time division duplex) system, the base station can also utilize channel reciprocity to carry out rational descending scheduling.
Have only periodic SRS to send in the LTE R9 version, promptly network side is by the resource and the moment of RRC message arrangement UE transmission SRS, and UE sends SRS in the moment of configuration, and network side does not need scheduling.At present, the LTE R10 stage has been introduced aperiodic SRS, and aperiodic SRS needs network side to dispatch, and UE carries out the transmission of each aperiodic of SRS according to the situation of network side scheduling.
In the LTE system, UE can have continuous reception and DRX (Discontinuous Reception, discontinuous reception) two states under RRC (Radio Resource Control, Radio Resource control) connection status.Wherein, 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.
Particularly, the configuration of the periodicity of DRX, as shown in Figure 1.When each DRX cycle begins, be introduced into an of short duration continuous accepting state, be called on duraion (activationary time in cycle), its duration is determined by On Duration Timer.On Duration Timer can be defined as the continuous several subframes that can carry PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) that begin to count from the DRX cycle starting point.Whether during this period, UE need monitor PDCCH, distribute to check to have at its other resources.If terminal receives descending scheduling and downlink data during on duraion, will start other timers and carry out follow-up scheduling process; If terminal does not receive descending scheduling and downlink data during on duraion, will enter resting state, up to next DRX cycle, OnDuration Timer could receive downlink transfer when starting again.
UE if receive descending scheduling and downlink transfer, can start following timer during on duration, indication UE further monitors PDCCH:
DRX Inactivity Timer (the non-Active Timer of DRX): start when receiving the PDCCH that dispatches new data, between the starting period, UE monitors PDCCH always; End condition is this timer expiry or the MAC layer signaling of receiving forced termination.
HARQ RTT Timer (HARQ Round Trip Time Timer, hybrid heavily referring to automatically asked the round-trip delay timer): at downlink transfer, start when receiving the PDCCH of dispatching downlink data, regular length is a retransmission time interval, during this period, unless covered by other timers, otherwise, need not monitor PDCCH.
DRX Retransmission Timer (DRX retransmission timer): at downlink transfer, the overtime back of HARQ RTTTimer starts, and between the starting period, UE monitors PDCCH always; End condition is this timer expiry or receives the retransfer scheduling of expectation.
Contention Resolution Timer (competition solves 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 between the starting period, UE monitors PDCCH always; End condition is this timer expiry or successfully receives competition solution message.
By above-mentioned configuring condition as can be known, the active time (activationary time) of UE correspondence is relevant with the DRX operation, and the subframe that UE need monitor PDCCH all belongs to active time.As shown in Figure 2, open the example that DRX inactivity timer prolongs active time for UE receives scheduling, the subframe that UE receives on duraion is received the PDCCH scheduling, and UE can open DRX inactivity timer, thereby prolongs activetime.In addition, DRX Retransmission Timer and Contention Resolution Timer may prolong the active time of UE equally.
The inventor is in realizing process of the present invention, and there are the following problems at least to find prior art:
In the prior art, the base station can adopt RRC message that the SRS of UE configuration cycle property is sent.When UE was configured the DRX reception, UE was as long as just need carry out the transmission of SRS at active time, and when being in non active time (non-activationary time), the SRS of UE does not send.As shown in Figure 3, the subframe that UE receives on duration is received the PDCCH scheduling, prolongs active time thereby UE opens DRX inactivitytimer.When UE is in the active time that prolongs owing to DRX inactivity timer, there is cycle SRS resource, need to send SRS.
Hence one can see that, and the active time of UE is determined comprehensively that by scheduling and various timer very irregular, when UE was in non active time state and does not send SRS, the base station was difficult to give other UE uses with the SRS resource-sharing that UE is between non-active period.
Summary of the invention
