Description

CDRX parameter configuration method and device

technical field

The present invention relates to the technical field of wireless communication, in particular to a method and device for configuring CDRX parameters.

Background technique

The purpose of introducing the DRX (Discontinuous Reception, discontinuous reception) function in the connection state of the LTE (Long Term Evolution, long-term evolution) and NR (New Radio, new air interface) system is to meet the UE (User Equipment, terminal) service QoS (Quality of Service, quality of service), save terminal power consumption and improve terminal experience. For some non-real-time services that are relatively sudden, such as FTP (File Transfer Protocol) services and WWW (World Wide Web, World Wide Web) services, the UE can enter the sleep state after receiving the data without monitoring data, thereby reducing terminal power consumption.

The DRX function divides the RRC_CONNECTED (radio resource control_connection) state of the UE into two different states: OnDuration and Opportunity for DRX. As shown in Figure 1, when the UE is in the active state, the UE needs to continuously monitor and Blind detection of PDCCH (Physical Downlink Control Channel, physical downlink control channel), and can report CQI (Channel Quality Indicator, channel quality indicator) / RI (Rank Indicator, rank indicator) / PMI (Precoding Matrix Indicator, precoding matrix indicator) information and Send SRS (Sounding Reference Signal, Sounding Reference Signal). When the UE is in the silent state, the UE does not need to monitor the PDCCH, nor does the UE need to report CQI/RI/PMI information and send SRS. Wherein, DRX Cycle is a DRX cycle.

DRX features involve multiple DRX timers, including onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, drxShortCycleTimer and HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request) RTT (Round Trip Time, round-trip delay) Timer, long DRX cycle , short DRX cycle and DRX start offset. Through various timers and parameter configurations, the operation mechanism and cooperation relationship of various timers, when the UE has data to send or receive, it can be in the active state to monitor the PDCCH channel. When there is no data to send or receive, the UE can In the silent state, there is no need to monitor and blindly detect the PDCCH, so as to achieve the purpose of terminal power saving.

Related technologies also stipulate that periodic SRS, semi-persistent SRS, and CSI (Channel State Information, channel state information) information cannot be sent during the silent period, and aperiodic SRS should be sent no matter what the situation is.

Among them, the SRS is used for uplink channel information acquisition, downlink channel information acquisition satisfying channel reciprocity, and uplink beam management. In the LTE system, SRS resources can only be configured on the last symbol of each subframe; in the NR system, there are more resource positions available for SRS, which can be flexibly configured through high-layer signaling. For different uses of the SRS, the base station can configure different SRS resource sets for the terminal, and indicate the use of the SRS resource sets through high-layer signaling.

In order to obtain downlink channel information through SRS measurement using channel reciprocity, the number of antennas that UE transmits at the same time may be less than the number of antennas received. The NR system designs the SRS antenna switching transmission method for this situation. The transceiver capabilities of the terminal are as follows: T=R, or 1T2R, or 1T4R, or 2T4R, where T represents the number of antennas for transmission, R represents the number of antennas for reception, and the base station must configure at least one for the terminal for downlink CSI The obtained SRS resource set.

In the related technology, as shown in FIG. 2 , the configuration of the DRX onduration timer and drx-LongCycleStartOffset should meet the requirement of including all SRS resource sending positions, so as to ensure that a complete SRS resource can be received once in each DRX cycle. For example, the SRS period is 20ms. For 1T4R SRS signal rotation, the worst configuration is that the SRS is configured on 4 special subframes. If it is necessary to receive or send all the SRSs, it takes 20ms. This requires the DRX onduration timer to be configured at least 20ms, which will seriously increase the power consumption of the terminal.

Or the configuration of DRX onduration timer and drx-LongCycleStartOffset does not consider the SRS resource location at all, and adopts a fixed value configuration.

When the network is transmitting downlink service data, according to the channel reciprocity, the SRS sent by the terminal can be used to calculate the downlink beamforming coefficient, which is used to send PDSCH (Physical Downlink Shared Channel, physical downlink shared channel); or according to the PMI reported by the terminal Send downlink PDSCH.

In related technologies, the configuration of onduration timer and drx-LongCycleStartOffset either includes a complete SRS resource, or the configuration of RX onduration timer and drx-LongCycleStartOffset does not consider the location of the SRS resource at all, and adopts a fixed value configuration. The former solution will cause the onduration timer configuration time to be too long and affect the power consumption of the terminal, and the latter solution will cause incomplete SRS information and affect network performance.
