Description

Terminal, base station, and sensing method

[0001] The present invention relates to a terminal, a base station, and a sensing method in a wireless communication system.

[0002] NR (New Radio) (also known as "5G"), the successor system to LTE (Long Term Evolution), introduces technologies that meet the requirements of a large-capacity system, high-speed data transmission, low latency, simultaneous connection of a large number of terminals, low cost, and low power consumption.

[0003] 3GPP (registered trademark) is also studying ISAC (Integrated Sensing and Communication), which uses nodes within the 3GPP (registered trademark) system to sense surrounding objects. With ISAC, there is no need to install a SIM card in the object to be sensed, and the object's position and other information are sensed by signal reflection.

[0004] 3GPP TS 38.331 V18.0.0 (2023-12)

[0005] In a terminal, an abnormality (e.g., abnormal heat generation, low battery, etc.) may occur while performing a sensing operation. The sensing operation may be, for example, transmitting a sensing signal or monitoring a sensing signal. However, operations based on conventional technology have a problem in that the terminal cannot respond to the abnormality appropriately (e.g., quickly and flexibly).

[0006] The present invention has been made in consideration of the above points, and aims to provide a technology that enables a terminal performing sensing operations to appropriately deal with an abnormality when the abnormality occurs.

[0007] According to the disclosed technology, a terminal is provided that includes: a control unit for performing a sensing operation; and a transmission unit that, when deactivating sensing is desired, transmits preference information indicating a desire to deactivate sensing to a base station.

[0008] According to the disclosed technology, when an abnormality occurs in a terminal performing a sensing operation, a technology is provided that enables the terminal to appropriately deal with the abnormality.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below is an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0011] In the operation of the wireless communication system according to the embodiment of the present invention, existing technologies are used as appropriate. However, the existing technologies are, for example, the existing LTE or the existing NR, but are not limited to the existing LTE or NR.

[0012] In addition, in the embodiments of the present invention described below, terms such as SS (Synchronization signal), PSS (Primary SS), SSS (Secondary SS), PBCH (Physical broadcast channel), PRACH (Physical random access channel), PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PUCCH (Physical Uplink Control Channel), and PUSCH (Physical Uplink Shared Channel) used in existing LTE or NR may be used. This is for convenience of description, and similar signals, functions, etc. may be called by other names.

[0013] Furthermore, in the embodiment of the present invention, the duplex method may be a time division duplex (TDD) method, a frequency division duplex (FDD) method, or another method (for example, flexible duplex, etc.).

[0014] Furthermore, in the embodiments of the present invention, "configuring" radio parameters etc. may mean that predetermined values ​​are pre-configured, or that radio parameters notified from the base station 10 or the terminal 20 are set.

[0015] (System Configuration) Fig. 1 is a diagram showing a configuration example (1) of a wireless communication system according to an embodiment of the present invention. As shown in Fig. 1, the wireless communication system according to the embodiment of the present invention includes a base station 10 and a terminal 20. Although Fig. 1 shows one base station 10 and one terminal 20, this is an example, and there may be a plurality of each.

[0016] The base station 10 is a communication device that provides one or more cells and performs wireless communication with the terminal 20. The physical resources of a wireless signal are defined in the time domain and the frequency domain, and the time domain may be defined by the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, and the frequency domain may be defined by the number of subcarriers or the number of resource blocks. Furthermore, a transmission time interval (TTI) in the time domain may be a slot, or a subframe.

[0017] The base station 10 transmits a synchronization signal and system information to the terminal 20. The synchronization signal is, for example, NR-PSS and NR-SSS. The system information is transmitted, for example, via NR-PBCH and is also referred to as broadcast information. The synchronization signal and system information may be referred to as SSB (SS / PBCH block). As shown in FIG. 1, the base station 10 transmits control signals or data to the terminal 20 via DL (Downlink) and receives control signals or data from the terminal 20 via UL (Uplink). Both the base station 10 and the terminal 20 are capable of transmitting and receiving signals by performing beamforming. Furthermore, both the base station 10 and the terminal 20 are capable of applying MIMO (Multiple Input Multiple Output) communication to the DL or UL. Furthermore, both the base station 10 and the terminal 20 may communicate via a secondary cell (SCell: Secondary Cell) and a primary cell (PCell: Primary Cell) using CA (Carrier Aggregation). Furthermore, the terminal 20 may perform communication via a primary cell of the base station 10 and a primary secondary cell group cell (PSCell: Primary SCG Cell) of another base station 10 by DC (Dual Connectivity).

[0018] The terminal 20 is a communication device equipped with a wireless communication function, such as a smartphone, a mobile phone, a tablet, a wearable terminal, or an M2M (Machine-to-Machine) communication module. As shown in FIG. 1, the terminal 20 receives control signals or data from the base station 10 via DL and transmits control signals or data to the base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. The terminal 20 also receives various reference signals transmitted from the base station 10 and measures propagation path quality based on the reception results of the reference signals. The terminal 20 may also be referred to as a UE, and the base station 10 may also be referred to as a gNB.

[0019] Fig. 2 is a diagram illustrating an example (2) of a wireless communication system according to an embodiment of the present invention. Fig. 2 shows an example of the configuration of a wireless communication system in which DC (Dual Connectivity) is implemented. As shown in Fig. 2, a base station 10A serving as a Master Node (MN) and a base station 10B serving as a Secondary Node (SN) are provided. The base station 10A and the base station 10B are each connected to a core network. The terminal 20 can communicate with both the base station 10A and the base station 10B.

[0020] The cell group provided by the base station 10A, which is an MN, is called an MCG (Master Cell Group), and the cell group provided by the base station 10B, which is an SN, is called an SCG (Secondary Cell Group). In addition, in DC, the MCG is composed of one PCell and one or more SCells, and the SCG is composed of one PSCell (Primary SCG Cell) and one or more SCells.

[0021] The processing operations in this embodiment may be executed in the system configuration shown in FIG. 1, in the system configuration shown in FIG. 2, or in any other system configuration.

[0022] (ISAC (Integrated Sensing And Communication)) As mentioned above, 3GPP (registered trademark) is studying ISAC, which uses nodes within the 3GPP (registered trademark) system to sense surrounding objects. Figure 3 shows an example of ISAC implementation on the 3GPP (registered trademark) system.

[0023] In ISAC, there is no need to install a SIM card in the object to be sensed; the object's location and other information are sensed by signal reflection. Both the base station 10 and the terminal 20 can function as both a transmitting node and a receiving node. Specific use cases include intruder detection in smart homes, drone flight position tracking, and object detection on public roads.

[0024] In addition, the preceding SA ISAC study in 3GPP (registered trademark) defines the following requirements (TR 22.837): "Subject to regulation and operator policy, the 5G network shall be able to activate, configure, and deactivate 5G wireless sensing based on parameters such as location and network conditions (e.g., network load)." In other words, the 5G NW can activate / configure / deactivate sensing depending on the situation. Although there has been no specific discussion of sensing deactivation, activation / configure / deactivation may be performed at a granularity such as per terminal 10 / base station 20 or per radio resource.

[0025] (Regarding Sensing Architecture) This embodiment deals with the case where the transmitter or receiver is the terminal 10. Examples of sensing patterns in the case where the transmitter or receiver is the terminal 10 are shown in Figs. 4 and 5. Figs. 4 and 5 show examples in which the sensing target is an object 30 (drone, etc.).

[0026] In the example shown in Fig. 4, the terminal 20 receives a sensing signal reflected from the object 30. In the example shown in Fig. 5, the terminal 20 transmits a sensing signal.

[0027] In addition, in this embodiment, many operations for deactivation of sensing are performed, so an example of an operation for deactivation of sensing will be described here.

[0028] When the base station 10 functioning as a transmitter is deactivated, the base station 10 stops transmitting the sensing signal and releases the wireless resource for transmitting the sensing signal.When the base station 10 functioning as a receiver is deactivated, the base station 10 stops monitoring the sensing signal and releases the wireless resource for sensing.

[0029] When the terminal 20 functioning as a transmitter is deactivated, the terminal 20 stops transmitting the sensing signal. The terminal 20 may also release the radio resource used for transmitting the sensing signal.

[0030] When the terminal 20 functioning as a receiver is deactivated, the terminal 20 stops monitoring the sensing signal and may also release the wireless resource for sensing.

[0031] (Operation when an abnormality occurs) The operation when an abnormality occurs in the terminal 20 during a sensing operation will be described. Here, as a specific example, it is assumed that the terminal 20 during a sensing operation becomes abnormally hot or experiences a low battery (low battery capacity).

[0032] A terminal 20 that falls into such a situation may request deactivation of sensing from the NW (specifically, the base station 10) in order to stop transmitting sensing signals or to stop monitoring sensing signals.

[0033] In this situation, based on the current 3GPP (registered trademark) specifications, the terminal 20 is considered to operate as follows.

[0034] [In the Case of Abnormal Heat Generation] Step 0: The terminal 20 detects abnormal heat generation.

[0035] Step 1: The terminal 20 waits for the NW to perform RRC Reconfiguration.

[0036] Step 2: When the NW performs RRC Reconfiguration, the terminal 20 reports the abnormal heat to the NW by using UE Assistance information.

[0037] Step 3: The NW determines that sensing in the terminal 20 is deactivated.

[0038] However, since the NW may determine that it is possible to deal with abnormal heat generation by various methods other than sensing deactivation (eg, SCell release), sensing may not necessarily be deactivated even in this case.

[0039] [In the Case of Low Battery] Since the UE Assistance information does not include an IE for notifying low battery, the terminal 20 cannot perform an operation that leads to deactivation of sensing.

[0040] (Regarding the Problems) As described above, in the operation based on the conventional technology, the terminal 20 cannot stop the sensing operation at its own discretion. Therefore, the terminal 20 cannot appropriately (quickly and flexibly) deal with an abnormality (e.g., abnormal heat generation, low battery, etc.) that occurs during the sensing operation.

[0041] Hereinafter, embodiments 1 to 3 will be described as embodiments for solving the above problems. Furthermore, since embodiment 1 is divided into embodiment 1A and embodiment 1B, each will be described separately. In the following description, it is assumed that, similar to the configuration shown in FIG. 4, when the terminal 20 receives a sensing signal, the base station 10 transmits the sensing signal. Furthermore, it is assumed, similar to the configuration shown in FIG. 5, when the terminal 20 transmits a sensing signal, the base station 10 receives the sensing signal. In other words, it is assumed that a sensing operation is being performed between the base station 10 and the terminal 20.

[0042] (Embodiment 1A) First, embodiment 1A will be described. In embodiment 1A, the sensing operation of the terminal 20 may be an operation of receiving a sensing signal or an operation of transmitting a sensing signal.

[0043] In embodiment 1A, the terminal 20 can report a preference to deactivate sensing to the base station 10. The terminal 20 may report the preference using a new IE in the IE:UEAssistanceInformation.

[0044] Furthermore, the preference may be reported on a UE-by-UE basis, or on a radio resource-by-radio resource basis where sensing is being performed.

[0045] An example of UEAssistanceInformation used when reporting preference on a UE-by-UE basis is shown in Fig. 6. In the example shown in Fig. 6, sensing-DeactivationPreference is a new IE, and when the base station 10 receives a message from the terminal 20 in which sensingDeactivationPreferred (a preference for deactivation) is set in this IE, the base station 10 can determine that the terminal 20 desires deactivation of the sensing operation.

[0046] <Processing Flow> An example of the processing procedure of the terminal 20 / base station 10 will be described along the procedure of the flowchart shown in Fig. 7. In S101, the terminal 20 / base station 10 performs RRC reconfiguration.

[0047] If the terminal 20 desires sensing deactivation (Yes in S102), the process proceeds to S103, and if the terminal 20 does not desire sensing deactivation (No in S102), the process proceeds to S104. The terminal 20 desires sensing deactivation when, for example, an abnormality occurs in the terminal 20 (for example, abnormal heat generation, low battery).

[0048] In S103, the terminal 20 includes sensing deactivation preference information in the UE assistance information, and the process proceeds to S105.

[0049] In S104, if the terminal 20 determines that UAI (UE assistance information) transmission is necessary for reasons other than sensing deactivation (Yes in S104), it proceeds to S105, and if it determines that it is not necessary (No in S104), it proceeds to S106.

[0050] In S105, the terminal 20 transmits the UE assistance information to the base station 10. In S106, the terminal 20 ends the process without transmitting the UE assistance information.

[0051] In S105, the base station 10 receives the UE assistance information from the terminal 20. In S107, the base station 10 determines whether to perform sensing deactivation based on the information included in the UE assistance information.

[0052] For example, if the UE assistance information includes a preference indicating that the terminal 20 desires sensing deactivation, the base station 10 performs sensing deactivation at the base station 10 and transmits a signal (e.g., RRC signaling, MAC CE, DCI) instructing sensing deactivation to the terminal 20. The terminal 20 that receives the signal instructing sensing deactivation deactivates its sensing operation. As a result, the terminal 20 that transmits a sensing signal stops transmitting the sensing signal. Furthermore, the terminal 20 that receives the sensing signal stops monitoring the sensing signal.

[0053] (Embodiment 1B) Next, embodiment 1B will be described. In embodiment 1B as well, the sensing operation of the terminal 20 may be an operation of receiving a sensing signal or an operation of transmitting a sensing signal.

[0054] In embodiment 1B, the terminal 20 can report a preference to activate or deactivate sensing to the base station 10. The terminal 20 may report the preference using a new IE in the IE:UEAssistanceInformation.

[0055] Furthermore, the preference may be reported on a UE-by-UE basis, or on a radio resource-by-radio resource basis where sensing is being performed.

[0056] 8 shows an example of UEAssistanceInformation used when reporting preference on a UE-by-UE basis. In the example shown in Fig. 8, sensing-DeactivationPreference is a new IE. In embodiment 1B, the terminal 20 can select sensingActivationPreferred (preference for activation) or sensingDeactivationPreferred (preference for deactivation) as information to be included in sensing-DeactivationPreference.

[0057] The processing flow in embodiment 1B is basically the same as the flow in Fig. 7 described in embodiment 1A. However, in embodiment 1B, in S102 of Fig. 7, the terminal 20 has three options: {want sensing deactivation, want sensing activation, or want neither}. If sensing deactivation or sensing activation is desired, the process proceeds to S103, and if neither is desired, the process proceeds to S104. In S107, the base station 10 can determine whether to perform sensing deactivation or sensing activation.

[0058] For example, a terminal 20 performing a sensing operation transmits UE assistance information to the base station 10 including a preference indicating that the terminal desires sensing deactivation due to an abnormality, and the terminal 20 has sensing deactivated by the base station 10.

[0059] Subsequently, since the abnormality is resolved, the terminal 20 wishes to resume sensing and transmits UE assistance information including a preference indicating that sensing activation is desired to the base station 10, and sensing is activated by the base station 10.

[0060] Effect of First Embodiment According to the first embodiment, the terminal 20 can request the base station 10 to deactivate sensing at its own discretion. As a result, the terminal 20 can deal more quickly and flexibly with an abnormality (e.g., abnormal heat generation, low battery) that occurs during a sensing operation.

[0061] Second Embodiment Next, a second embodiment will be described. In the second embodiment, the sensing operation of the terminal 20 is an operation of receiving a sensing signal. That is, in the second embodiment, a case where the terminal 20 operates as a receiver will be described.

[0062] In the second embodiment, the terminal 20 can stop monitoring the sensing signal before reporting to the base station 10. The terminal 20 autonomously stopping monitoring the sensing signal may be expressed as the terminal 20 autonomously deactivating sensing. Such an operation may also be called UE-initiated sensing deactivation.

[0063] After the terminal 20 stops monitoring the sensing signal, the terminal 20 may request the base station 10 to perform sensing deactivation. After the terminal 20 stops monitoring the sensing signal, the terminal 20 may report to the base station 10 that it has performed sensing deactivation. This report may indicate a request to the base station 10 to perform sensing deactivation.

[0064] The terminal 20 may request / report deactivation using a new IE in the IE: UEAssistanceInformation.

[0065] Furthermore, the request / report of deactivation may be made on a UE basis or on a radio resource basis where sensing is being performed.

[0066] Fig. 9 shows an example of UEAssistanceInformation used when requesting / reporting deactivation on a UE-by-UE basis. In the example shown in Fig. 9, sensing-DeactivationReport is a new IE, and when the base station 10 receives a message from the terminal 20 in which true (information indicating a request for deactivation) is set in this IE, the base station 10 can determine that the terminal 20 requests the base station 10 to deactivate sensing.

[0067] <Processing Flow> An example of the processing procedure of the terminal 20 / base station 10 will be described according to the procedure of the flowchart shown in Fig. 10. In S201, the terminal 20 that is monitoring the sensing signal stops monitoring the sensing signal because it detects an abnormality (e.g., abnormal heat generation, low battery), for example.

[0068] In S202, the terminal 20 / base station 10 executes RRC reconfiguration. In S203, the terminal 20 transmits UE assistance information including a sensing deactivation report to the base station 10.

[0069] In S204, the base station 10 performs sensing deactivation for the terminal 20. For example, the base station 10 stops transmitting a sensing signal and releases its radio resources. The base station 10 may also transmit a signal (e.g., RRC signaling, MAC CE, DCI) to the terminal 20 indicating that sensing deactivation has been performed.

[0070] According to the second embodiment, the terminal 20 can stop monitoring the sensing signal at its own discretion. As a result, the terminal 20 can deal with an abnormality (e.g., abnormal heat generation, low battery) that occurs during the sensing operation more quickly and flexibly.

[0071] Third Embodiment Next, a third embodiment will be described. In the third embodiment, the sensing operation of the terminal 20 is an operation of transmitting a sensing signal. That is, in the third embodiment, a case where the terminal 20 operates as a transmitter will be described.

[0072] In the third embodiment, the terminal 20 can stop transmitting the sensing signal before reporting to the base station 10. The terminal 20 autonomously stopping the transmission of the sensing signal may be expressed as the terminal 20 autonomously deactivating sensing. Such an operation may also be called UE-initiated sensing deactivation.

[0073] After the terminal 20 stops transmitting the sensing signal, the terminal 20 may request the base station 10 to perform sensing deactivation. After the terminal 20 stops transmitting the sensing signal, the terminal 20 may report to the base station 10 that it has performed sensing deactivation. This report may indicate a request to the base station 10 to perform sensing deactivation.

[0074] The terminal 20 may request / report deactivation using a new IE in the IE: UEAssistanceInformation.

[0075] Furthermore, the request / report of deactivation may be made on a UE basis, or may be made on a radio resource basis where sensing operation is being performed.

[0076] An example of UEAssistanceInformation used when requesting / reporting deactivation on a UE-by-UE basis is shown in Fig. 11. In the example shown in Fig. 11, sensing-DeactivationReport is a new IE, and when the base station 10 receives a message from the terminal 20 in which true (information indicating a request for deactivation) is set in this IE, the base station 10 can determine that the terminal 20 requests the base station 10 to deactivate sensing.

[0077] <Processing Flow> An example of the processing procedure of the terminal 20 / base station 10 will be described along the steps of the flowchart shown in Fig. 12. In S301, the terminal 20 that is transmitting a sensing signal stops transmitting the sensing signal because it detects an abnormality (e.g., abnormal heat generation, low battery).

[0078] In S302, the terminal 20 / base station 10 executes RRC reconfiguration. In S303, the terminal 20 transmits UE assistance information including a sensing deactivation report to the base station 10.

[0079] In S304, the base station 10 performs sensing deactivation for the terminal 20. For example, the base station 10 stops monitoring the sensing signal and releases the radio resources. In addition, the base station 10 may transmit a signal (e.g., RRC signaling, MAC CE, DCI) indicating that sensing deactivation has been performed to the terminal 20.

[0080] According to the third embodiment, the terminal 20 can stop transmitting a sensing signal at its own discretion. As a result, the terminal 20 can deal with an abnormality (e.g., abnormal heat generation, low battery) that occurs during sensing more quickly and flexibly.

[0081] (Embodiment 4 (Variation)) In embodiments 2 and 3, the sensing operation is distinguished between the transmission of a sensing signal and the monitoring of a sensing signal, but this is just an example. The sensing deactivation report may be made without distinguishing between the transmission of a sensing signal and the monitoring of a sensing signal. Furthermore, the sensing operation may be an operation different from either the transmission of a sensing signal or the monitoring of a sensing signal.

[0082] An embodiment in which the sensing operation does not distinguish between sending a sensing signal and monitoring a sensing signal will be described as a fourth embodiment.

[0083] In the fourth embodiment, the terminal 20 can stop the sensing operation before reporting to the base station 10. The terminal 20 autonomously stopping the sensing operation may be expressed as the terminal 20 autonomously deactivating sensing. Such an operation may also be called UE-initiated sensing deactivation.

[0084] After the terminal 20 stops the sensing operation, the terminal 20 may request the base station 10 to perform sensing deactivation. After the terminal 20 stops the sensing operation, the terminal 20 may report to the base station 10 that it has performed sensing deactivation. This report may indicate a request to the base station 10 to perform sensing deactivation.

[0085] The terminal 20 may request / report deactivation using a new IE in the IE: UEAssistanceInformation. The deactivation request / report may be made on a UE-by-UE basis or on a radio resource-by-radio resource basis where sensing is being performed. Specific examples of the IE are the same as those shown in FIG. 9 and the like.

[0086] The processing flow is basically the same as that shown in Figures 10 and 12. However, in S201 / S301, the terminal 20 performing the sensing operation stops the sensing operation because it detects an abnormality (e.g., abnormal heat generation, low battery). The subsequent processing is the same as that in the second and third embodiments described with reference to Figures 10 and 12.

[0087] According to the fourth embodiment, the terminal 20 can stop the sensing operation at its own discretion. As a result, the terminal 20 can deal with an abnormality (e.g., abnormal heat generation, low battery) that occurs during the sensing operation more quickly and flexibly.

[0088] (Device Configuration) Next, a description will be given of an example of the functional configuration of the base station 10 and the terminal 20 that execute the processes and operations described above. Note that the base station 10 is an example of the NW described above.

[0089] <Base Station 10> Fig. 13 is a diagram showing an example of the functional configuration of the base station 10. As shown in Fig. 13, the base station 10 has a transmitting unit 110, a receiving unit 120, a setting unit 130, and a control unit 140. The functional configuration shown in Fig. 13 is merely an example. As long as the operations related to the embodiment of the present invention can be performed, the names of the functional divisions and functional units may be any. Furthermore, the transmitting unit 110 and the receiving unit 120 may be collectively referred to as a communication unit.

[0090] The transmitter 110 has a function of generating a signal to be transmitted to the terminal 20 and transmitting the signal wirelessly. The receiver 120 has a function of receiving various signals transmitted from the terminal 20 and acquiring, for example, information of a higher layer from the received signal. The transmitter 110 also has a function of transmitting, to the terminal 20, NR-PSS, NR-SSS, NR-PBCH, DL / UL control signals, DCI via PDCCH, data via PDSCH, and the like.

[0091] The setting unit 130 stores preset setting information and various setting information to be transmitted to the terminal 20 in a storage device provided in the setting unit 130, and reads out the information from the storage device as needed.

[0092] The control unit 140 controls the base station 10. The control unit 140 also executes or controls sensing operations. The functional unit in the control unit 140 related to signal transmission may be included in the transmitting unit 110, and the functional unit in the control unit 140 related to signal reception may be included in the receiving unit 120. The transmitting unit 110 may also be called a transmitter, and the receiving unit 120 may also be called a receiver.

[0093] <Terminal 20> Fig. 14 is a diagram showing an example of the functional configuration of the terminal 20. As shown in Fig. 14, the terminal 20 has a transmitting unit 210, a receiving unit 220, a setting unit 230, and a control unit 240. The functional configuration shown in Fig. 14 is merely an example. As long as the operations related to the embodiment of the present invention can be performed, the names of the functional divisions and functional units may be any. The transmitting unit 210 and the receiving unit 220 may be collectively referred to as a communication unit.

[0094] The transmitter 210 creates a transmission signal from the transmission data and transmits the transmission signal wirelessly. The receiver 220 receives various signals wirelessly and acquires higher layer signals from the received physical layer signals. The receiver 220 also has the function of receiving NR-PSS, NR-SSS, NR-PBCH, DL / UL / SL control signals, DCI via PDCCH, data via PDSCH, etc. transmitted from the base station 10. Furthermore, for example, the transmitting unit 210 may transmit a PSCCH (Physical Sidelink Control Channel), a PSSCH (Physical Sidelink Shared Channel), a PSDCH (Physical Sidelink Discovery Channel), a PSBCH (Physical Sidelink Broadcast Channel), or the like to another terminal 20 as D2D communication, and the receiving unit 120 may receive the PSCCH, the PSSCH, the PSDCH, the PSBCH, or the like from the other terminal 20.

[0095] The setting unit 230 stores various setting information received from the base station 10 or other terminals by the receiving unit 220 in a storage device provided in the setting unit 230, and reads it from the storage device as needed.

[0152] As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

[0153] As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0154] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

[0155] When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Furthermore, when the term "or" is used in this disclosure, it is not intended to be an exclusive or.

[0156] A radio frame may be composed of one or more frames in the time domain. Each of the one or more frames in the time domain may be called a subframe. A subframe may further be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0157] Numerology may be communication parameters that apply to the transmission and / or reception of a signal or channel, such as subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering operations performed by the transceiver in the frequency domain, specific windowing operations performed by the transceiver in the time domain, etc.

[0158] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may be a time unit based on numerology.

[0159] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (or PUSCH) mapping type B.

[0160] The radio frame, subframe, slot, minislot, and symbol all represent time units for transmitting signals, and may be referred to by other names corresponding to the radio frame, subframe, slot, minislot, and symbol.

[0161] For example, one subframe may be called a transmission time interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, or the like instead of a subframe. Furthermore, one slot may be called a unit time. The unit time may differ for each cell depending on the numerology.

[0162] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate wireless resources (such as frequency bandwidth and transmission power that can be used by each terminal 20) to each terminal 20 in TTI units. Note that the definition of TTI is not limited to this.

[0163] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0164] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0165] A TTI having a time length of 1 ms may be called a regular TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0166] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and greater than or equal to 1 ms.

[0167] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of the numerology, for example, 12. The number of subcarriers included in an RB may be determined based on the numerology.

[0168] The time domain of an RB may include one or more symbols and may have a length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

[0169] Note that one or more RBs may also be called a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0170] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0171] A Bandwidth Part (BWP) (which may also be referred to as a fractional bandwidth) may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0172] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be set for the terminal 20 within one carrier.

[0173] At least one of the configured BWPs may be active, and the terminal 20 may not expect to transmit or receive a predetermined signal / channel outside the active BWP. Note that the terms "cell," "carrier," and the like in this disclosure may be read as "BWP."

[0174] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples, and various changes may be made to the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc.

[0175] In this disclosure, where articles are added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.

[0176] In the present disclosure, the term "A and B are different" may mean "A and B are different from each other." The term may also mean "A and B are each different from C." Terms such as "separate" and "coupled" may also be interpreted in the same way as "different."

[0177] The aspects / embodiments described in this disclosure may be used alone, in combination, or switched depending on the implementation. Notification of predetermined information (e.g., notification that "X is true") is not limited to explicit notification, but may be implicit (e.g., not notifying the predetermined information).

[0178] Although the present disclosure has been described in detail above, it is clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in modified and altered forms without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the description of the present disclosure is intended to be illustrative and does not have any limiting meaning on the present disclosure.
