Description

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for setting a reception mode, a storage medium, and an electronic device.

[ background of the invention ]

Physical Downlink Control Channel (PDCCH) monitoring is usually based on detection of Cyclic Redundancy Check (CRC) Check, and the PDCCH is considered to be detected only after the CRC Check is passed. The PDCCH detection method has the advantages of low missed detection rate, but has the problems of high processing complexity and high power consumption.

In order to solve the above problem, a conventional PDCCH detection method determines in advance whether or not a PDCCH is present based on PDCCH Demodulation Reference Signal (DMRS) detection to reduce power consumption. Although the power consumption is effectively reduced, the missed detection rate is greatly improved, especially in a low signal-to-noise ratio scene.

Therefore, the current PDCCH detection method cannot achieve the receiving effects of low power consumption and low missed detection rate at the same time.

[ detailed description ] embodiments

For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.

It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Fig. 1 is a flowchart of a receiving mode setting method according to an embodiment of the present invention, as shown in fig. 1, the method includes:

step 101, judging whether the current scene is in a first detection state.

And 102, if the current scene is judged to be in the first detection state, setting a receiving mode as a first receiving mode.

In the technical scheme of the receiving mode setting method provided by the embodiment of the invention, whether the current scene is in a first detection state is judged; and if the current scene is judged to be in the first detection state, setting a receiving mode as a first receiving mode. In the embodiment of the invention, when the NR-U equipment executes the PDCCH detection, the scenes are classified according to the scene configuration, and different scenes adopt different receiving modes, thereby achieving the receiving effects of low energy consumption and low missed detection rate.

Fig. 2 is a flowchart of a receiving mode setting method according to another embodiment of the present invention, as shown in fig. 2, the method includes:

step 201, judging whether the current scene is in a first detection state, if so, executing step 202; if not, go to step 203.

In the embodiment of the invention, each step is executed by a New Radio-Unlicensed (NR-U) device. The NR-U device may configure two PDCCH search space set groups at most for supporting more frequent PDCCH monitoring outside of a Channel Occupancy Time (COT). The two PDCCH search space set groups include a search space set Group0# and a search space set Group1 #. Thus, the state of the current scene includes a Group0# PDCCH detection state or a Group1# PDCCH detection state.

The search space set Group0# corresponds to a PDCCH outside the COT, and the PDCCH needs to be monitored based on a mini-slot. The search space set Group1# corresponds to the PDCCH in the COT and needs to monitor the PDCCH on the slot basis.

As shown in fig. 3, the UE starts the PDCCH monitoring of Group0#, and once detecting the PDCCH of Group0#, the next slot delayed by P symbols may start the PDCCH monitoring of Group1 #. At the same time, Group1 monitoring counters are started, and when the counters expire or the COT ends, Group1 switches to Group 0. Where the P value depends on the processing power of the UE.

In this embodiment of the present invention, the first detection state includes a Group1# PDCCH detection state.

Step 202, the receiving mode is set to the first receiving mode.

In the embodiment of the present invention, the first reception mode includes a high-reliability PDCCH reception mode. In order to reduce the PDCCH missed detection rate, the high-reliability PDCCH receiving mode generally needs to demodulate a log-likelihood ratio (LLR) of the PDCCH, and then perform decoding blind detection based on the LLR, and only after CRC check is passed, a valid PDCCH signal is considered to be detected.

In the embodiment of the invention, if the current scene is in a Group1# PDCCH detection state, the probability of PDCCH signals existing in corresponding COT is very high, and ReceiverState is set to HighPerfMode, namely, a receiving mode adopts a high-reliability PDCCH receiving mode.

Step 203, judging whether the current scene is in a second detection state, if not, executing step 204; if yes, go to step 205.

In this embodiment of the present invention, the second detection state includes a Group0# PDCCH detection state.

And step 204, setting the receiving mode to be a third receiving mode.

In an embodiment of the invention, the third reception mode comprises NULL.

In the embodiment of the invention, if the current scene is neither the Group0# PDCCH detection state nor the Group1# PDCCH detection state, the ReceiverState is set to NULL, and the receiver is in an idle state.

Step 205, determining whether the signal-to-noise ratio is greater than a preset threshold, if so, executing step 206; if not, go to step 202.

In the embodiment of the invention, if the current scene is in a Group0# PDCCH detection state, the corresponding COT outer PDCCH detection is further divided into two scenes according to the signal-to-noise ratio. One scenario is that the signal-to-noise ratio is greater than a preset threshold value, and the other scenario is that the signal-to-noise ratio is less than or equal to the preset threshold value.

Step 206, setting the receiving mode to a second receiving mode.

In this embodiment of the present invention, the second reception mode includes a low power consumption PDCCH reception mode. The low power PDCCH reception mode is a mode for saving PDCCH detection power consumption, and usually determines whether a PDCCH signal is present based on PDCCH DMRS energy or related detection. When the PDCCH DMRS energy or the related detection result is greater than a preset threshold, the PDCCH signal is considered to exist, otherwise, the PDCCH signal is considered not to exist.

In the embodiment of the invention, if the signal-to-noise ratio is greater than the preset threshold value th _ SNR, the PDCCH is in a strong signal scene at the moment, the detection is easy to be correct, the receiverState is set to be LowPowerMode, namely, the receiving mode adopts a low-power PDCCH receiving mode; otherwise, the current scene is considered to be in a weak signal scene, the missed detection of the PDCCH is easy to occur, at the moment, the receiverState is set to be LowPowerMode, namely, the receiving mode adopts a high-reliability PDCCH receiving mode, and the missed detection of the PDCCH is avoided.

Fig. 4 is a schematic structural diagram of a receiving mode setting apparatus according to an embodiment of the present invention, as shown in fig. 4, the apparatus includes: a first judging module 31, a receiving mode setting module 32, a second judging module 33 and a third judging module 34.

The first determining module 31 is configured to determine whether the current scene is in a first detection state.

The receiving mode setting module 32 is configured to set the receiving mode to the first receiving mode if the first determining module 31 determines that the current scene is in the first detection state.

In the embodiment of the present invention, the first reception mode includes a high-reliability PDCCH reception mode.

And a second determining module 33, configured to determine whether the current scene is in a second detection state.

The receiving mode setting module 32 is further configured to set the receiving mode to a third receiving mode if the second determining module 33 determines that the current scene is not in the second detection state.

In an embodiment of the invention, the third reception mode comprises NULL.

And a third determining module 34, configured to determine whether the signal-to-noise ratio is greater than a preset threshold.

The receiving mode setting module 32 is further configured to set the receiving mode to the second receiving mode if the third determining module 34 determines that the signal-to-noise ratio is greater than the preset threshold.

In this embodiment of the present invention, the second reception mode includes a low power consumption PDCCH reception mode.

The receiving mode setting module 32 is further configured to set the receiving mode to the first receiving mode if the third determining module 34 determines that the signal-to-noise ratio is smaller than or equal to the preset threshold.
