[0056] Figure 1 Shown is a simplified structural diagram of a communication system according to an embodiment of the present application;

[0057] Figure 2 FIG. 4 is a schematic diagram of a four-step random access timing sequence according to an embodiment of the present application. DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0059] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0060] Figure 1 FIG. 1 is a schematic diagram of a communication system according to an embodiment of the present application. Figure 1 As shown, the base station 110 communicates with the user equipment 120 based on the NR protocol. The user equipment 120 can randomly access the channel of the base station 110.

[0061] For the Random Access Channel (RACH) process, generally 4 steps (4-step random access) or 2 steps (2-step random access) are required. Figure 2 The following is a timing flow chart of the 4-step random access. Figure 2As shown, for the 4-step random access, the first step (S301) is that the user equipment 120 sends a physical random access channel (Physical Random Access Channel, PRACH), also known as message 1 (Message 1, Msg1); the second step (S302) is that the base station 110 sends a random access response (Random Access Response, RAR), also known as message 2 (Message 2, Msg2); the third step (S303) is that the user equipment 120 sends a message 3 (Message 3, Msg3), and message 3 can carry a high-level message of RRCSetupRequest; the fourth step (S304) is that the base station 110 sends a message 4 (Message 4, Msg4), and the user equipment can confirm that the contention access is successful by receiving message 4, that is, the base station confirms that the random access request of the user equipment (with the user equipment identification code) is accepted, and message 4 can carry a high-level message of RRCSetup. Generally, Msg1 may include a random access preamble or PRACH or random access preamble transmission; Msg2 may include RAR or random access response reception; Msg3 may include a physical uplink shared channel (PUSCH) scheduled by RAR uplink; Msg4 may include a physical downlink shared channel (PDSCH) with a UE contention resolution identifier. Since each step of the RACH process (e.g., S301-S304) is basically control signaling, it may be considered to configure these control signaling as short control signaling.

[0062] However, the time domain position of the user equipment 120 sending message 1 is uncertain, the time domain position of the base station 110 sending message 2 is also uncertain (the user equipment needs blind detection in the RAR window), the time domain position of the user equipment 120 sending message 3 is scheduled by the base station through message 2, and the time domain position of the base station sending message 4 is also uncertain (the user equipment needs blind detection). Therefore, if these control signalings (messages 1 / 2 / 3 / 4) are directly configured as short control signalings, the total duration of these control signalings may exceed 10 milliseconds within 100 milliseconds, that is, the condition of short control signaling is not met.

[0063] In response to the above problems, the present application proposes a communication solution based on a short control signaling window, which defines a short control signaling window. The base station sends control signaling that needs to be configured as short control signaling within the short control signaling window. In this way, the sending time of the control signaling can be concentrated in one window.

[0064] Specifically, a group of short control signaling windows is defined within a time interval (for example, the first time interval), and the sending opportunities and duration of each sending opportunity of the group of short control signaling windows within the time interval are defined, or the period and duration of the short control signaling window are directly defined (under the period and duration, the short control signaling window has a relatively fixed sending opportunity and duration of each sending opportunity within the time interval). For example, a group of short control signaling windows is defined to have a sending opportunity of 20 milliseconds each (i.e., the sending starting point is the 0th, 20th, 40th, 60th, and 80th milliseconds) within 100 milliseconds (a value of the first time interval), and the duration of each sending opportunity is 2 milliseconds, so that the total sending time within 100 milliseconds is 10 milliseconds, which meets the short control signaling condition. Alternatively, the period of the short control signaling window is directly defined as 20 milliseconds and the duration is 2 milliseconds, and the effect is the same, and the total sending time within 100 milliseconds is 10 milliseconds, which meets the short control signaling condition.

[0065] Since the base station sends control signaling that needs to be configured as short control signaling within 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 the short control signaling window.

[0066] Specifically, the user equipment 120 determines a group of short control signaling windows within a first time interval (eg, 100 milliseconds).

[0067] For example, in one embodiment, the user equipment 120 determines a set of transmission opportunities of the short control signaling window within the first time interval and the duration of each transmission opportunity.

[0068] For another example, in one embodiment, the user equipment 120 determines the period and duration of the short control signaling window.

[0069] Furthermore, the first time interval is a duration associated with the definition of short control signaling, for example, 100 milliseconds. Therefore, directly defining the period and duration of the short control signaling window may cause the short control signaling window to appear inconsistently in different 100 milliseconds when the short control signaling window has no multiple relationship with 100 milliseconds. Therefore, the period and duration of the short control signaling window may be limited to be valid only within a first time interval.

[0070] Specifically, in one embodiment, the user equipment 120 determines whether the period and duration of the short control signaling window are valid only within a first time interval.

[0071] Further, when only the sending opportunity of the short control signaling window is configured, and the duration of each sending opportunity is defined to be the same, the user equipment 120 only needs to know the sending opportunities (number) within the first time interval (such as within 100 milliseconds) to derive the duration of each sending opportunity (such as 100 milliseconds divided by the number of sending opportunities). In this way, the configuration overhead of the base station 110 can be effectively simplified.

[0072] Therefore, in one embodiment, the user equipment 120 determines the sending opportunities of the group of short control signaling windows within the first time interval; and calculates the duration of the short control signaling windows at the sending opportunities according to the number of the sending opportunities.

[0073] Furthermore, since the SSB in the unlicensed spectrum is the main channel and signal for initial access and measurement / synchronization, the short control signaling usually needs to include the SSB, that is, the short control signaling window needs to include the SSB. Therefore, in order 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 through the time domain position (such as period) of the SSB.

[0074] Therefore, in one embodiment, the user equipment 120 determines the period of the short control signaling window according to the period of the SSB. This can be done in the following ways:

[0075] The period of the short control signaling window is equal to the period of the SSB;

[0076] The period of the short control signaling window is equal to 1 / X times the SSB period, where X is an integer greater than zero. In this way, the short control signaling window has more transmission opportunities than the SSB, but the duration of each transmission opportunity is shorter.

[0077] The period of the short control signaling window is equal to X times the SSB period, where X is an integer greater than zero, so that the short control signaling window has fewer transmission opportunities than the SSB, but the duration of each transmission opportunity is longer.

[0078] Further, in one embodiment, the base station sends a periodic reference signal or a periodic channel in the 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.

[0079] In addition, when the period of the periodic reference signal or the periodic channel cannot be divided by the first time interval (for example, 100 milliseconds), the transmission timing of the periodic reference signal or the periodic channel in different first time intervals will be different, so it may not be within the short control signaling window, because the transmission timing of the short control signaling window in the first time interval is the same. One method is to limit the period of the periodic reference signal or the periodic channel to be divided by the first time interval. Another method is for the user equipment 120 to determine that the period configured for the periodic reference signal or the periodic channel is within a time interval, such as 100 milliseconds, 50 milliseconds, etc.

[0080] 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. Configured PUSCH is a semi-statically configured PUSCH that does not require dynamic scheduling. It can also be called a configured grant PUSCH or a configured granted uplink transmission, and can also be called a high-level configured PUSCH or a high-level configured uplink transmission. Configured PDSCH is a semi-statically configured PDSCH that does not require dynamic scheduling. It can also be called a semi-persistently scheduled PDSCH (Semi-Persitent Scheduling, SPS) or a semi-persistently scheduled downlink reception, and can also be called a high-level configured PDSCH or a high-level configured downlink reception.

[0081] Furthermore, for Figure 2 In the four-step random access shown, in one embodiment, the user equipment 120 sends message 1 in the short control signaling window without performing LBT, or the message 1 in the short control signaling window belongs to short control signaling. The user equipment 120 sends message 3 in the short control signaling window without performing LBT, or the message 3 in the short control signaling window belongs to short control signaling.

[0082] Furthermore, in the unlicensed spectrum, since the base station 110 may not always be able to obtain a transmission opportunity, Figure 2In the four-step random access shown, the length of the RAR window (for the user equipment 120 to blindly detect the physical downlink control channel (PDCCH) of the RAR) needs to be extended to increase the transmission opportunities of the base station 110. However, this will also increase the power consumption caused by the user equipment 120 blindly detecting the PDCCH of the RAR. Therefore, it is necessary to limit the user equipment 120 to blindly detect the PDCCH of the RAR only within the short control signaling window, so that the base station 110 can send the PDCCH of the RAR without LBT.

[0083] Specifically, in one embodiment, the user equipment 120 blindly detects the PDCCH of the RAR only within the short control signaling window.

[0084] Furthermore, in Figure 2 In the four-step random access shown, message 3 is scheduled by message 2. In the case of network congestion, it is difficult for the user equipment 120 to obtain a transmission opportunity (LBT failure) on the time domain resource scheduled by message 2, and thus message 3 cannot be sent.

[0085] In view of the above situation, in one embodiment, message 2 schedules message 3 in the short control signaling window, so that the user equipment does not need LBT to send message 3. However, the sending opportunities of the short control signaling window in the time interval (100 milliseconds) are sparse (such as a sending opportunity every 20 milliseconds). Message 2 needs to schedule message 3 in the next short control signaling window, and the scheduling offset may be large (such as 20 milliseconds). In the high frequency band, the subcarrier spacing of data may be 480kHz or 960kHz, and the corresponding scheduling shift is a lot of time slots. 20 milliseconds corresponds to 640 time slots under the 480kHz subcarrier spacing and 1280 time slots under the 960kHz subcarrier spacing. Such a large number of time slots may be difficult to accommodate in the Time Domain Resource Allocation (TDRA) table.

[0086] Therefore, in one embodiment, if the time domain position of message 3 exceeds the last time slot of the short control signaling window where message 2 is located, then the user equipment 120 determines that the time domain position of message 3 is time slot x, and time slot x is the time slot of the next short control signaling window of the short control signaling window where message 2 is located.

[0087] Specifically, in one embodiment, the user equipment 120 determines the time slot x as 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.

[0088] In another embodiment, if there is no uplink resource after the RAR PDCCH detected in the current short control signaling window, the user equipment does not detect the RAR PDCCH. This can reduce the power consumption of the user equipment.

[0089] Further, in one embodiment, the user equipment 120 sends a sounding reference signal (SRS), a physical uplink control channel (PUCCH) or a configured PUSCH in a short control signaling window, and LBT is not required, or the SRS, PUCCH or configured PUSCH in the short control signaling window belongs to short control signaling. SRS, PUCCH and configured PUSCH are all periodic channels / signals, so once configured in the short control signaling window, the user equipment can know that these channels / signals belong to short control signaling.

[0090] Further, in one embodiment, the user equipment 120 is scheduled to send a PUSCH in a short control signaling window (different from a configured PUSCH, this PUSCH is dynamically scheduled), and no LBT is required, or the PUSCH scheduled in the short control signaling window belongs to short control signaling. In this way, the resources in the short control signaling window can be used as efficiently as possible.

[0091] Further, in one embodiment, when a channel or a signal has a symbol outside the short control signaling window, the user equipment 120 needs LBT before sending the channel or the signal.

[0092] Further, in one embodiment, the user equipment 120 may also be informed that the SSB is a short control signaling based on the short control signaling window. The base station 110 configures the short control signaling window. The user equipment 120 receives the SSB within the short control signaling window. By configuring the short control signaling window, the base station 110 may tell the user equipment 120 that it only needs to measure the SSB within the short control signaling window.

[0093] It is to be understood that some or all of the steps or operations in the above embodiments are merely examples, and the present application embodiments may also perform other operations or variations of various operations. In addition, the various steps may be performed in different orders presented in the above embodiments, and it is possible that not all of the operations in the above embodiments need to be performed.

[0094] Furthermore, in the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the access party programming the device. Designers can "integrate" a digital device on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0095] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.

[0096] Specifically, the device proposed in the embodiment of the present application can be fully or partially integrated into a physical entity during actual implementation, or it can be physically separated. And these modules can all be implemented in the form of software calling through processing elements; they can also be all implemented in the form of hardware; some modules can also be implemented in the form of software calling through processing elements, and some modules can be implemented in the form of hardware. For example, the detection module can be a separately established processing element, or it can be integrated in a chip of an electronic device. The implementation of other modules is similar. In addition, all or part of these modules can be integrated together, or they can be implemented independently. In the implementation process, each step of the above method or each of the above modules can be completed by an integrated logic circuit of hardware in a processor element or instructions in the form of software.

[0097] 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 (ASIC), or one or more digital signal processors (DSP), or one or more field programmable gate arrays (FPGA), etc. For another example, these modules may be integrated together and implemented in the form of a system-on-a-chip (SOC).

[0098] An embodiment of the present application further proposes an electronic device (e.g., user device 120), which includes 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 execute the method steps described in the embodiment of the present application.

[0103] Specifically, in an embodiment of the present application, the processor and the memory can be combined into a processing device, more commonly, they are independent components, and the processor is used to execute the program code stored in the memory to implement the method described in the embodiment of the present application.
