Description

Technical Field

The present application relates to the field of communications technologies, and in particular, to a control signaling decoding method and an electronic device.

Background

In the high-band unlicensed spectrum, short control signaling (short control signaling) may be employed in accordance with regulations. The short control signaling may also be referred to as contention-free short control signaling (contention extension short control signaling) and may also be referred to as listen-before-talk-free operation (LBT extension operation).

Specifically, in the Rel-15 NR protocol of the 5G New Radio (NR), when the total duration of the short control signaling does not exceed 10 ms within the observation time of 100 ms, the short control signaling can be transmitted without listening Before speaking (LBT). Therefore, the use of short control signaling can ensure that some important control signaling can be sent out as soon as possible or on time, thereby improving the system reliability and causing less interference (smaller duty cycle).

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the 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 application.

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

Fig. 1 is a diagram illustrating a communication system according to an embodiment of the present application. As shown in fig. 1, the base station 110 and the user equipment 120 communicate based on the NR protocol. The user equipment 120 can randomly access a channel of the base station 110.

For a Random Access Channel (RACH) procedure, 4 steps (4-step Random Access) or 2 steps (2-step Random Access) are generally required. Fig. 2 is a timing flowchart of 4-step Random Access, and as shown in fig. 2, for 4-step Random Access, the first step (S301) is that the ue 120 sends a Physical Random Access Channel (PRACH), also called Message 1 (Message 1, msg 1); the second step (S302) is that the base station 110 sends a Random Access Response (RAR), which is also called Message 2 (Message 2, msg 2); the third step (S303) is that the ue 120 sends a Message 3 (Message 3, msg 3), where the Message 3 may carry a higher layer Message of the RRCSetupRequest; the fourth step (S304) is that the base station 110 sends a Message 4 (Message 4, msg 4), and the ue can confirm that the contention access is successful by receiving the Message 4, i.e. the base station confirms that the random access request of the ue (with the ue id) is received, and the Message 4 can carry a high-level Message of RRCSetup. Generally, msg1 may include a Random access preamble (Random access preamble) or a PRACH or Random access preamble transmission (Random access preamble transmission); msg2 may include RAR or Random access feedback reception (Random access response reception); msg3 may include a Physical Uplink Shared Channel (PUSCH) for RAR Uplink scheduling; the Msg4 may include a Physical Downlink Shared Channel (PDSCH) with a UE contention resolution identity. Since each step (e.g., S301 to S304) of the RACH procedure is basically control signaling, it may be considered to use the control signaling configured as short control signaling.

However, the time domain position of the ue 120 sending the message 1 is indefinite, the time domain position of the bs 110 sending the message 2 is indefinite (the ue needs to perform blind detection in the RAR window), the time domain position of the ue 120 sending the message 3 is scheduled by the bs through the message 2, and the time domain position of the bs sending the message 4 is indefinite (the ue needs to perform blind detection). Therefore, if these control signalings (messages 1/2/3/4) are configured directly as short control signalings, the total duration of these control signalings may exceed 10 milliseconds within 100 milliseconds, i.e. the conditions for short control signaling are not met.

In view of the above problems, the present application provides a communication scheme based on a short control signaling window, which defines the short control signaling window, and a base station sends a control signaling that needs to be configured as a short control signaling in the short control signaling window, so that the sending time of the control signaling can be centralized in one window.

Specifically, a set of short control signaling windows is defined within a time interval (e.g., a first time interval), the transmission occasions and the duration of each transmission occasion of the set of short control signaling windows within the time interval are defined, or the period and the duration of the short control signaling windows are directly defined (at which the short control signaling windows have a relatively fixed transmission occasion and duration on each transmission occasion within the time interval). For example, a group of short control signaling windows is defined to have 20 ms each (i.e. 0 th, 20 th, 40 th, 60 th, 80 th ms as a transmission start point) of transmission timing within 100 ms (one value of the first time interval), and have 2 ms duration on each transmission timing, so that the total transmission time is 10 ms within 100 ms, and the short control signaling condition is satisfied. Or, the period of the short control signaling window is directly defined to be 20 milliseconds, the duration is 2 milliseconds, the effect is the same, and the total sending time is 10 milliseconds within 100 milliseconds, so that the short control signaling condition is met.

Since the base station sends the control signaling which needs to be configured as the short control signaling in the short control signaling window, the user equipment needs to know the short control signaling window to correctly receive the short control signaling. Therefore, the present application proposes a new control signaling decoding method in which the user equipment 120 determines a short control signaling window.

In particular, the user equipment 120 determines a set of short control signaling windows within a first time interval (e.g., 100 milliseconds).

For example, in an embodiment, the user equipment 120 determines the transmission occasions and the duration on each transmission occasion of a set of short control signaling windows within a first time interval.

For another example, in an embodiment, the user equipment 120 determines the period and duration of the short control signaling window.

Further, the first time interval is a duration associated with the definition of the short control signaling, e.g., 100 milliseconds. Therefore, the period and duration of the short control signaling window are directly defined, and when the short control signaling window has no multiple relation with 100 milliseconds, the occurrence timings of the short control signaling window in different 100 milliseconds may be inconsistent, so that the period and duration of the short control signaling window can be limited to be valid only in one first time interval.

Specifically, in one embodiment, the user equipment 120 determines whether the period and duration of the short control signaling window is valid only for a first time interval.

Further, when only the sending occasions of the short control signaling window are configured and the duration time on each sending occasion is defined to be the same, the ue 120 only needs to know the sending occasions (number) in the first time interval (for example, in 100 ms), and can derive the duration time on each sending occasion (for example, 100 ms divided by the number of sending occasions). This effectively simplifies the configuration overhead of the base station 110.

Thus, in an embodiment, the user equipment 120 determines the transmission occasions of the set of short control signaling windows within the first time interval; and calculating the duration of the short control signaling window on the sending opportunity according to the number of the sending opportunities.

Further, since the SSB in the unlicensed spectrum is the primary channel and signal for initial access and measurement/synchronization, the short control signaling needs to include the SSB, that is, the short control signaling window needs to include the SSB. Therefore, to simplify the configuration overhead, in an embodiment of the present application, the time domain position of the short control signaling window is associated with the time domain position of the SSB, so that the user equipment 120 can derive the time domain position of the short control signaling window according to the time domain position (e.g., the period) of the SSB.

Thus, in an embodiment, the user equipment 120 determines the period of the short control signaling window according to the period of the SSB. It may be in the following manner:

the period of the short control signaling window is equal to the period of the SSB;

the period of the short control signaling window is equal to 1/X times of the SSB period, wherein X is an integer greater than zero, so that the short control signaling window has more sending occasions than SSB, but the duration on each sending occasion is shorter;

the short control signaling window has a period equal to X times the SSB period, where X is an integer greater than zero, such that the short control signaling window is fewer than the transmission occasions of the SSB, but longer in duration on each transmission occasion.

Further, in an embodiment, the base station transmits the periodic reference signal or the periodic channel within a short control signaling window. The user equipment 120 determines the period of the periodic reference signal or the periodic channel according to the short control signaling window.

In addition, when the period of the periodic reference signal or the periodic channel is not evenly divisible by the first time interval (e.g., 100 ms), the transmission timings of the periodic reference signal or the periodic channel in different first time intervals may be different, and thus may not be within the short control signaling window because the transmission timings of the short control signaling window in the first time interval are the same. One approach is to limit the period of the periodic reference signal or periodic channel to be divided by the first time interval. Another method is for the user equipment 120 to determine that the period in which the periodic reference signal or the periodic channel is configured is within a time interval, such as 100 ms, 50 ms, etc.

Specifically, the periodic Reference Signal may include a Channel State Information Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), and a Positioning Reference Signal (PRS). The periodic Channel may include a configured Physical Uplink Share Channel (PUSCH), a configured Physical Downlink Share Channel (PDSCH), and/or a PDCCH. The Configured PUSCH is a semi-statically Configured PUSCH and does not require dynamic scheduling, and may be referred to as a configuration-granted PUSCH (Configured grant PUSCH) or a configuration-granted uplink transmission, or may be referred to as a higher-layer Configured PUSCH or a higher-layer Configured uplink transmission. The Configured PDSCH is a Semi-statically Configured PDSCH and does not require dynamic Scheduling, and may be referred to as Semi-persistent Scheduled PDSCH (SPS) or Semi-persistent scheduled downlink reception, or may be referred to as higher-layer Configured PDSCH or higher-layer Configured downlink reception.

Further, for the four-step random access shown in fig. 2, in an embodiment, the ue 120 sends the message 1 within the short control signaling window, does not perform LBT, or the message 1 within the short control signaling window belongs to the short control signaling. The user equipment 120 sends message 3 within the short control signaling window without LBT, or message 3 within the short control signaling window belongs to the short control signaling.

Further, in the unlicensed spectrum, since the base station 110 may not always obtain the transmission opportunity, in the four-step random access shown in fig. 2, the length of the RAR window (Physical Downlink Control Channel (PDCCH) for the user equipment 120 to blindly detect the RAR) needs to be extended to increase the transmission opportunity of the base station 110. However, this also increases power consumption caused by the user equipment 120 blindly detecting the PDCCH of the RAR, and therefore, the user equipment 120 needs to be limited to blindly detecting the PDCCH of the RAR only in the short control signaling window, so that the base station 110 can send the PDCCH of the RAR without LBT.

Specifically, in an embodiment, the ue 120 only blindly detects the PDCCH of the RAR within the short control signaling window.

Further, in the four-step random access shown in fig. 2, message 3 is scheduled by message 2. In case of network congestion, it is difficult for the user equipment 120 to get a transmission opportunity (LBT failure) on the time domain resource scheduled by message 2, and thus cannot transmit message 3.

For the above case, in one embodiment, message 2 schedules message 3 within the short control signaling window, so that the user equipment sends message 3 without LBT. However, the sending occasions of the short control signaling window in the Time interval (100 ms) are sparse (for example, 20 ms is one sending occasion), the message 2 is to schedule the message 3 in the next short control signaling window, the Scheduling offset (Scheduling offset) may be larger (for example, 20 ms level), in the high frequency band, the subcarrier interval of the data may be 480kHz or 960kHz, the corresponding Scheduling translation amount is many slots (slots), 20 ms corresponds to 640 slots in 480kHz subcarrier interval, and corresponds to 1280 slots in 960kHz subcarrier interval, and such a large number of slots may be difficult to accommodate in a Time Domain Resource Allocation (TDRA) table.

Therefore, in an embodiment, if the time domain position of the message 3 exceeds the last time slot of the short control signaling window in which the message 2 is located, the ue 120 determines that the time domain position of the message 3 is the time slot x, and the time slot x is the time slot of the next short control signaling window of the short control signaling window in which the message 2 is located.

Specifically, in an embodiment, the ue 120 determines that the time slot x is the scheduling offset of the next short control signaling window minus the interval y, where the interval y is the interval from the message 2 time slot to the last time slot of the short control signaling window where the message 2 is located.

In another embodiment, if there is no uplink resource after the RAR PDCCH detected in the current short control signaling window, the ue does not detect the RAR PDCCH. This may reduce user equipment power consumption.

Further, in an embodiment, the ue 120 sends Sounding Reference Signal (SRS), physical Uplink Control Channel (PUCCH) or configured PUSCH in the short Control signaling window, without LBT, or the SRS, PUCCH or configured PUSCH in the short Control signaling window belongs to the short Control signaling. SRS, PUCCH and configured PUSCH are periodic channels/signals, so once configured within the short control signaling window, the user equipment may know that these channels/signals belong to short control signaling.

Further, in an embodiment, the user equipment 120 is scheduled to transmit PUSCH within a short control signaling window (unlike a configured PUSCH, which is dynamically scheduled), LBT is not required, or the scheduled PUSCH within the short control signaling window belongs to short control signaling. This allows for as efficient a use of resources within the short control signaling window as possible.

Further, in one embodiment, when a channel or signal has a symbol outside the short control signaling window, the ue 120 needs LBT before transmitting the channel or signal.

Further, in an embodiment, the user equipment 120 may also be made aware that the SSB is the short control signaling based on the short control signaling window. The base station 110 configures a short control signaling window. The user equipment 120 receives the SSB within a short control signaling window. By configuring the short control signaling window, the base station 110 can tell the user equipment 120 that the SSB need only be measured within the short control signaling window.

It is to be understood that some or all of the steps or operations in the above-described embodiments are merely examples, and other operations or variations of various operations may be performed by the embodiments of the present application. Further, the various steps may be performed in a different order presented in the above embodiments, and not all of the operations in the above embodiments may be performed.

Further, in the 90's of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical blocks. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by an accessing party. A digital device is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate specialized integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development, but the original code before compiling is also written in a specific Programming Language, which is called Hardware Description Language (HDL), and the HDL is not only one kind but many kinds, such as abll (Advanced boot Expression Language), AHDL (alternate hard Description Language), traffic, CUPL (computer universal Programming Language), HDCal (Java hard Description Language), lava, lola, HDL, PALASM, software, rhydl (Hardware Description Language), and vhul-Language (vhyg-Language), which is currently used in the field. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in purely computer readable program code means, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

Specifically, the apparatuses proposed in the embodiments of the present application may be wholly or partially integrated into one physical entity or may be physically separated when actually implemented. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling by the processing element in software, and part of the modules can be realized in the form of hardware. For example, the detection module may be a separate processing element, or may be integrated into a chip of the electronic device. Other modules are implemented similarly. In addition, all or part of the modules can be integrated together or can be independently realized. In implementation, each step of the above method or each module above may be implemented by an integrated logic circuit of hardware in a processor element or an instruction in the form of software.

For example, the above modules may be one or more integrated circuits determined to implement the above methods, such as: one or more Application Specific Integrated Circuits (ASICs), or one or more Digital Signal Processors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs), etc. For another example, these modules may be integrated together and implemented in the form of a System-On-a-Chip (SOC).

An embodiment of the present application further proposes an electronic device (e.g. user equipment 120) comprising a memory for storing computer program instructions and a processor for executing the program instructions, wherein, when the computer program instructions are executed by the processor, the electronic device is triggered to perform the method steps as described in the embodiments of the present application.

Further, the processor may have the functionality to operate one or more software programs, which may be stored in the storage medium.

Specifically, in one embodiment of the present application, the memory of the electronic device may be a read-only memory (ROM), other types of static memory devices that can store static information and instructions, a Random Access Memory (RAM), or other types of dynamic memory devices that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compact disc, laser disc, optical disc, digital versatile disc, blu-ray disc, etc.), a magnetic disc storage medium, or other magnetic storage devices, or any computer-readable medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.
