The invention discloses a CQI reporting method, a CQI reporting device, a CQI indicating method, a CQI reporting device and a storage medium, which are used for reporting the CQI of a current DRX cycle in real time aiming at the current DRX cycle and improving the utilization efficiency of wireless resources. The CQI reporting method comprises the following steps: for any DRX cycle, receiving a PDCCH (physical downlink control channel) in downlink resources sent by a network side, wherein the PDCCH carries indication information whether to report a Channel Quality Indication (CQI) or not before a PDSCH (physical downlink shared channel) in an activation period On Duration of the DRX cycle; detecting a PDCCH in a downlink resource; and determining whether to report CQI before the PDSCH in the On Duration of the DRX cycle according to the indication information.

Description

CQI reporting method, CQI reporting device, CQI indicating method, CQI reporting device and CQI reporting device storage medium
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a CQI reporting method, a CQI reporting apparatus, and a CQI reporting apparatus indicating method, and a storage medium.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
A CQI (Channel Quality Indicator) is a measurement standard of communication Quality of a radio Channel. The channel quality of PDSCH is represented by 0 to 15. 0 indicates the worst channel quality and 15 indicates the best channel quality. CQI is the highest MCS (Modulation and Coding Scheme) used in the case where the proposed RI (rank indication) and PMI (Precoding Matrix Indicator) are used and the BLER (block error rate) of PDSCH (Physical Downlink Shared Channel) transmission is 10% at the highest.
When a UE (User Equipment) configures a C-DRX (Connected Discontinuous Reception) operation, the UE intelligence sends a periodic CQI during an active period (On Duration). When a base station (eNodeB) configures periodic CQI reporting using RRC (Radio Resource Control), the UE may be further restricted from transmitting CQI within the time of On Duration. In the discontinuous reception time, the time is divided into continuous DRX cycles in the time domain, as shown in fig. 1, which is a schematic diagram of the time domain configuration of the DRX cycles. The DRX cycle consists of "On Duration" and "Opportunity for DRX": in the time of "On Duration", the UE monitors and receives the PDCCH (active period); during the "Opportunity for DRX" time, the UE does not receive data of the downlink channel to save power consumption (sleep period).
Based On this, the selection of the MCS of the PDSCH located before the uplink subframe for reporting the CQI within the On Duration time in the current DRX cycle can only be based On the CQI reported by the On Duration in the previous DRX cycle. Since the wireless channel conditions are changing constantly, when the channel quality is good, if QPSK (Quadrature Phase Shift keying) is used for downlink transmission instead of the higher-order Modulation scheme (16 QAM)/64 QAM), the utilization rate of the spectrum is lowered, and the throughput is reduced. In case of poor channel quality, if high order modulation (16QAM/64QAM) is used instead of QPSK modulation, excessive retransmission is caused. In either case, the radio resources cannot be effectively used. Therefore, the determination of the MCS of the PDSCH within the "On Duration" time of the current DRX cycle is inaccurate based On the CQI reported in the last DRX cycle "On Duration".

Detailed Description
In order to realize reporting of the CQI of the current DRX cycle in real time aiming at the current DRX cycle and improve the utilization efficiency of wireless resources, the embodiment of the invention provides a CQI reporting method, a CQI reporting device and a storage medium.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
In order to better adapt to the change of wireless channels, the UE needs to report the CQI in a short time before the PDSCH in the On Duration of the current DRX cycle, so as to solve the problem that the UE receives inaccurate MCS of the PDSCH. As shown in fig. 2, which is a schematic diagram of an implementation flow of a CQI reporting method according to an embodiment of the present invention, the method includes the following steps:
s21, receiving PDCCH in downlink resource sent by the network side aiming at any discontinuous reception cycle DRX cycle.
Wherein, the PDCCH carries indication information whether to report CQI in the PDCCH before the PDSCH in the On Duration of the DRX cycle.
S22, detecting the PDCCH in the downlink resource;
s23, according to the indication information carried in the PDCCH, determining whether to report CQI before the PDSCH in the On Duration of the DRX cycle.
Step S21 may be implemented to send the PDCCH carrying the CQI indication information whether to report according to any of the following manners:
in a first embodiment, the PDCCH is transmitted in a downlink resource within a short time before the DRX cycle starts.
In this embodiment, the UE needs to wake up to detect the PDCCH at the Opportunity for DRX of the previous DRX cycle, and according to the indication information carried in the PDCCH, if it is determined that the CQI needs to be reported and it indicates that there is data transmission in the On Duration of the DRX cycle, it is determined to be activated in the On Duration of the DRX cycle, and the CQI is reported before the PDSCH; and if the CQI is determined not to need to be reported, the method indicates that no data is transmitted in the On Duration of the DRX cycle, and the method determines not to be activated in the active period On Duration of the DRX cycle and does not report the CQI before the PDSCH.
If the CQI needs to be reported, the network side may also carry an offset value (offset) between the downlink resource for sending the PDCCH and the uplink resource for reporting the CQI in the PDCCH, and the UE determines the uplink resource for reporting the CQI according to the offset value.
In specific implementation, the uplink resource for reporting the CQI by the UE may be On the latest uplink resource before the On Duration. For example, CQI may be reported in the last uplink subframe within Opportunity for DRX of the last DRX cycle.
In the second embodiment, the PDCCH in the downlink resource at the DRX cycle start position carries the indication information whether to report the CQI.
In this embodiment, if the first subframe at the starting position of the DRX cycle is a downlink subframe, the PDCCH of the downlink subframe may carry indication information indicating whether to report the CQI.
Similar to the first embodiment, in this embodiment, according to the indication information carried in the PDCCH, if it is determined that CQI needs to be reported and it indicates that there is data transmission in the On Duration of the DRX cycle, the UE determines to activate in the On Duration of the DRX cycle and reports CQI before the PDSCH; and if the CQI does not need to be reported, namely no data transmission exists in the On Duration of the DRX cycle, determining that the CQI is not reported in the activation period On Duration of the DRX cycle and before the PDSCH.
Similarly, if the CQI needs to be reported, the network side may also carry, in the PDCCH, an offset value (offset) between the downlink resource for sending the PDCCH and the uplink resource for reporting the CQI. And the UE determines the uplink resource for reporting the CQI according to the offset value. And between the PDCCH and CQI reporting, the terminal does not need to monitor the PDCCH any more and does not receive the PDSCH, and at this time, the PDCCH for scheduling the PUSCH (physical uplink shared channel) can be detected and the PUSCH transmission is carried out.
In the third embodiment, the PDCCH in the downlink resource at the non-starting position of the DRX cycle carries the indication information whether to report the CQI.
In this embodiment, it is described that the resource at the starting position of the DRX cycle is an uplink resource, so that the UE can report the CQI on the uplink resource, and therefore, the PDCCH sent on the downlink resource at the position may carry indication information for not reporting the CQI, and the indication information does not carry an offset value between the PDCCH and CQI reporting, and the UE determines not to report the CQI according to the received indication information, and at this time, the terminal may detect the PDCCH for scheduling PDSCH/PUSCH and perform PDSCH reception and PUSCH transmission.
Correspondingly, the embodiment of the invention also provides a CQI reporting indication method implemented by a network side, which comprises the following steps: aiming at any discontinuous reception cycle DRXcycle, a Physical Downlink Control Channel (PDCCH) sent to UE by using downlink resources carries indication information whether to report CQI, and the PDCCH is in front of a Physical Downlink Shared Channel (PDSCH) in an activation period On Duration of the DRX cycle.
Optionally, the indicating information of whether to report the CQI is carried in a downlink physical control channel PDCCH sent to the UE by using the downlink resource specifically includes:
indicating information whether to report CQI is carried in a PDCCH in a downlink resource before the DRX cycle; or
Indicating information whether to report CQI is carried in a PDCCH (physical Downlink control channel) in a downlink resource at the starting position of the DRX cycle; or
And indicating information for not reporting the CQI is carried in the PDCCH in the downlink resource at the DRXcycle non-starting position.
Optionally, if CQI needs to be reported, the PDCCH also carries an offset value between a downlink resource for sending the PDCCH and an uplink resource for reporting the CQI.
In the CQI reporting and indicating method provided in the embodiments of the present invention, aperiodic CQI reporting is triggered in a short time before PDSCH reception in an On Duration in a current DRX Cycle through PDCCH detection, so that a problem that a PDSCH MCS received by a UE is inaccurate is solved. The PDCCH can be detected in the latest downlink resource before the On Duration starts and in the downlink resource at the On Duration start position, so that the CQI of the current DRX cycle can be reported in real time aiming at the current DRX cycle, and the utilization efficiency of the radio resource is improved.
