Description

Terminal device, base station device, and wireless communication system

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

[0002] In today's networks, traffic from mobile devices (smartphones and feature phones) accounts for the majority of network resources. Furthermore, the traffic used by mobile devices is expected to continue to expand. In addition to traffic used by mobile devices, IoT (Internet of Things) services (e.g., transportation systems, smart meters, and monitoring systems for devices) are also being developed. Therefore, networks are being required to support services with diverse requirements. In order to accommodate such diverse services, the communication standards for fifth-generation mobile communications (5G or NR (New Radio)) (for example, Non-Patent Documents 1 to 14) include, in addition to the standard technologies of 4G (fourth-generation mobile communications), eMBB (Enhanced Mobile Broadband), Massive MTC (Machine Type Communications), and URLLC (Ultra-Reliable and Low Latency Communications). The standards are being formulated assuming support for many use cases.

[0003] In addition, in the working group of the 3rd Generation Partnership Project (3GPP (registered trademark)), an international standardization project, extension technologies for the above communication standards are currently being continuously studied and standardized.

[0004] For example, a 3GPP working group is considering the introduction of the SBFD (Subband Full Duplex) technology (Non-Patent Document 15), which aims to improve uplink latency and expand coverage by configuring uplink resources on downlink symbols and / or flexible symbols.

[0005] 3GPP TS 37.324 V17.0.03GPP TS 37.340 V17.7.03GPP TS 38.201 V17.0.03GPP TS 38.202 V17.5.03GPP TS 38.211 V17.6.03GPP TS 38.212 V17.7.03GPP TS 38.213 V17.8.03GPP TS 38.214 V17.8.03GPP TS 38.215 V17.4.03GPP TS 38.300 V17.7.03GPP TS 38.321 V17.7.03GPP TS 38.322 V17.3.03GPP TS 38.323 V17.5.03GPP TS 38.331 V17.7.03GPP TR 38.858 V18.0.0

[0006] SBFD, for example, configures uplink resources on downlink symbols. The uplink resources may be uplink subbands (UL subbands). The introduction of SBFD may cause a problem in which uplink channels and / or uplink signals are not located in the uplink subbands. This may occur because the positions of uplink channels and / or uplink signals are derived based on the number of resource blocks (RBs) in the uplink Bandwidth Part (BWP), but the number of RBs in the uplink subbands and the uplink BWP differ.

[0007] The disclosed technology has been made in view of the above, and aims to enable control so that uplink channels and / or uplink signals are located in uplink subbands.

[0008] In one aspect, a terminal device is provided that includes: a receiving unit that receives first information related to a UL subband configuration and second information related to uplink channel resources; a control unit that controls the uplink channel resources to be located on the UL subband according to the first information and the second information; and a transmitting unit that transmits the uplink channel using the resources.

[0009] It is possible to provide a terminal device, a base station device, a wireless communication system, etc., which can control an uplink channel and / or an uplink signal to be located in an uplink subband.

[0013] Hereinafter, embodiments of a base station, a terminal, and a wireless communication system disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the disclosed technology is not limited to the following embodiments. First Embodiment

[0014] FIG. 1 is a diagram illustrating an example of a wireless communication system according to a first embodiment. The wireless communication system 1 may include a base station device 100A, a base station device 100B, a terminal device 200A, a terminal device 200B, and a terminal device 200C. When the terminal device 200A, the terminal device 200B, and the terminal device 200C are not distinguished from each other, they are simply referred to as the terminal device 200. The base station device 100A forms a cell C10. The cell C10 may be referred to as the coverage of the base station device 100A. The base station device 100B forms a cell C11. The cell C11 may be referred to as the coverage of the base station device 100B. When the base station device 100A and the base station device 100B are not distinguished from each other, they are simply referred to as the base station device 100. The terminal device 200 is located within the coverage of one of the base station devices 100 .

[0015] The base station device 100 may be, for example, a small radio base station such as a macro radio base station or a pico radio base station (including a micro radio base station, a femto radio base station, etc.), or may be a radio base station of various scales, and may be referred to as a radio communication device, a communication device, a transmitting device, etc. The terminal device 200 may be, for example, a radio terminal such as a mobile phone, a smartphone, a PDA (Personal Digital Assistant), a personal computer, a vehicle, or any of various devices or equipment (sensor devices, etc.) having a radio communication function, and may be referred to as a radio communication device, a communication device, a receiving device, a mobile station, etc.

[0016] The base station device 100 is connected to a network device (not shown) (a higher-level device or another base station) via a wired connection. Note that the base station device 100 may be connected to the network device wirelessly instead of via a wired connection.

[0017] The base station device 100 may have a wireless communication function with the terminal device 200 and a digital signal processing and control function separated into separate devices. In this case, the device having the wireless communication function may be called an RRH (Remote Radio Head), and the device having the digital signal processing and control function may be called a BBU (Base Band Unit). The RRHs may be installed extending from the BBU, and they may be connected by a wired connection such as optical fiber. Alternatively, they may be connected wirelessly. Instead of the aforementioned RRH and BBU, the base station device 100 may be separated into, for example, a Central Unit (CU), a Distributed Unit (DU), and a Radio Unit (RU). The DU may include, for example, a MAC (Media Access Control) layer function. The DU may also include, for example, a function of an RLC (Radio Link Control) layer. The RU includes at least an RF wireless circuit. The DU and RU may also be integrated into one unit.

[0018] On the other hand, the terminal device 200 communicates with the base station device 100 via wireless communication.

[0019] Note that the base station device 100 performs processing for establishing a Radio Resource Control (RRC) connection when an RRC connection has not been established with the terminal device 200. Note that the processing for establishing an RRC connection may include a random access procedure.

[0020] Next, the base station device 100 will be described. Fig. 2 is a diagram showing an example of a functional configuration diagram of the base station device 100 in this embodiment. The base station device 100 has a wireless communication unit 110, a control unit 120, a storage unit 130, and a communication unit 140.

[0021] The wireless communication unit 110 is composed of a transmitting unit 111 and a receiving unit 112, and performs wireless communication with the terminal device 200. Specifically, the transmitting unit 111 transmits to the terminal device 200 downlink signals such as a random access procedure signal, a downlink physical signal, an RRC layer signal, a downlink data signal, and a downlink control signal.

[0022] Furthermore, the receiving unit 112 can receive uplink signals transmitted from the terminal device 200, such as random access procedure signals, RRC layer signals, uplink data signals, and uplink control signals.

[0023] The control unit 120 controls the base station device 100. Specifically, it can control the establishment of an RRC connection with the terminal device 200, signal processing of signals received by the receiving unit 112, creation of transmission blocks (TBs), mapping of the transmission blocks to radio resources, etc. The control unit 120 also calculates the transmission power of the downlink channel and / or the uplink channel and determines an RNTI (Radio Network Temporary Identifier).

[0024] The storage unit 130 can store, for example, downlink data signals.

[0025] The communication unit 140 connects to and communicates with a network device (e.g., a higher-level device or another base station) via a wired or wireless connection. The data signal received by the communication unit 140 and intended for the terminal device 200 can be stored in the storage unit 130.

[0026] Next, the terminal device 200 will be described. Fig. 3 is a diagram showing an example of a functional configuration diagram of the terminal device 200 in this embodiment. As shown in Fig. 3, the terminal device 200 includes a communication unit 210, a control unit 220, and a storage unit 230. These components are connected to enable unidirectional or bidirectional input and output of signals and data. The communication unit 210 can be described as being divided into a transmission unit 211 and a reception unit 212.

[0027] The transmitter 211 transmits data signals and control signals by wireless communication via an antenna. Note that the antenna may be common for both transmission and reception. The transmitter 211 transmits uplink signals such as random access procedure signals, RRC layer signals, uplink data signals, and uplink control signals.

[0028] The receiving unit 212 receives downlink signals, such as a random access procedure signal, a downlink data signal, and a downlink control signal, transmitted from the base station device 100. The received signals may also include reference signals used for channel estimation and demodulation, for example.

[0029] The control unit 220 controls the terminal device 200. Specifically, the control unit 220 can control the establishment of an RRC connection with the base station device 200, signal processing of signals received by the receiving unit 212, creation of transmission blocks (TBs), mapping of the transmission blocks to radio resources, etc. The control unit 220 can also calculate the transmission power of an uplink signal and / or an uplink channel and determine the RNTI.

[0030] The storage unit 230 can store, for example, an uplink data signal. The storage unit 230 can also store configuration information (or setting information) related to wireless communication transmitted from the base station device 100.

[0031] The wireless communication unit 110 of the base station device 100 and the communication unit 210 of the terminal device 200 may be configured to include an antenna port.

[0037] The higher layer parameters may be any or all of the following: RRC parameters, MAC Media Access Control Element (CE), System Information Block (SIB), and Master Information Block (MIB).

[0038] Here, an example of slots for wireless communication between the base station device 100 and the terminal device 200 will be described.

[0039] FIG. 4 is a diagram showing an example of a slot configuration in this embodiment. The radio frame shown in FIG. 4 may be 10 milliseconds (msec). The radio frame may also be called a frame. The radio frame may also be called a system frame. The radio frame is composed of, for example, 10 subframes.

[0040] In the radio frame shown in FIG. 4, for example, the length of the time axis of the radio frame is determined according to the subcarrier spacing (SCS). For example, the subcarrier spacing is SCS=15×2. μ (kHz). In other words, μ = 0 means that the subcarrier spacing is 15 kHz. Note that hereinafter, μ may be referred to as the value μ or the value μ that determines the subcarrier spacing.

[0041] In addition, with a subcarrier spacing of 15 kHz, one frame may include 10 slots. One slot may include, for example, 14 OFDM symbols. An OFDM symbol may be composed of, for example, multiple physical resource blocks (PRBs). One physical resource block may be composed of, for example, 12 subcarriers.

[0042] The slot is, for example, n using the subcarrier spacing μ.ｓ μ n ｓ μ For example, in one subframe, {0, 1, 2, ..., N ｓｌｏｔ subframe, μ-1} in increasing order. ｓ μ For example, in one frame, {0, 1, 2, ..., N ｓｌｏｔ ｆｒａｍｅ、μ -1} in ascending order. One slot is N ｓｙｍｂ ｓｌｏｔ may contain N OFDM symbols. ｓｙｍｂ ｓｌｏｔ may have different values ​​depending on the length of the cyclic prefix (CP).

[0043] FIG. 5 is a diagram showing an example of the relationship between the value μ, slots, frames, and subframes in this embodiment. Note that a normal CP may be used for all values ​​μ. Also, an extended CP may be used when μ=2. Regarding the length of the CP in the time domain, the normal CP may be shorter than the extended CP. Also, FIG. 7 shows the number N of slots included in one radio frame for the value μ. ｓｌｏｔ ｆｒａｍｅ、μ 1 shows an example of the number of slots included in one subframe for values ​​μ and μ. In the case of normal CP, for example, one slot includes 14 OFDM symbols. In the case of extended CP, for example, one slot includes 12 OFDM symbols. In the first embodiment, normal CP is assumed unless otherwise specified. Note that the technology in the first embodiment can be applied to normal CP and extended CP.

[0044] Note that subcarrier spacing may be referred to as numerology. Different numerologies may mean different subcarrier spacings.

[0045] The time resource may be one or more OFDM symbols, one or more slots, or one or more system frames.

[0046] The frequency resource may be one or more subcarriers. The frequency resource may be one or more PRBs.

[0048] If the long-scale property of a channel on which a symbol is transmitted on one antenna port can be used to predict the channel on which a different symbol is transmitted on the other antenna port, the two antenna ports may be said to be Quasi Co-located (QCL). The long-scale property may include some or all of one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial reception parameters.

[0049] For each numerology and carrier, the resource grid is N ｇｒｉｄ，ｘ ｓｉｚｅ，μ ×N ｓｃ ＲＢ subcarriers and N ｓｙｍｂ subframe, may be defined as μ OFDM symbols. ｓｃ ＲＢ may be 12.

[0050] FR1 (Frequency Range 1) may have a carrier frequency of 6 GHz or less, and FR2 may have a carrier frequency of 6 GHz or more.

[0051] TDD (Time Division Duplex) may also be called Unpaired Spectrum.

[0052] The Random Access Preamble Sequence supports four or more different lengths, which may include at least 139, 571, 839, and 1151.

[0053] A random access preamble sequence of length 839 may be applied to the 1.25 kHz and / or 5 kHz SCS. A random access preamble sequence of length 139 may be applied to the 15 kHz, 30 kHz, 60 kHz, 120 kHz, 480 kHz, and 960 kHz SCS. A random access preamble sequence of length 571 may be applied to the 30 kHz, 120 kHz, and / or 480 kHz SCS. A random access preamble sequence of length 1151 may be applied to the 15 kHz and / or 120 kHz SCS.

[0054] A plurality of PRACH preamble formats may be defined using one or more PRACH OFDM symbols, with different cyclic prefixes (CPs) and guard times. The PRACH preamble configuration may be provided to the terminal device 200 in system information.

[0055] The PUCCH (Physical Uplink Control Channel) may carry UCI (Uplink Control Information) from the terminal device 200 to the base station device 100. The PUCCH may have five formats depending on the number of PUCCH symbols (period) and the UCI payload size.

[0056] PUCCH format 0 may be a short PUCCH consisting of one or two symbols. PUCCH format 0 may have the capacity to multiplex up to six terminal devices 200 with a 1-bit payload in the same PRB. UCI transmitted in PUCCH format 0 may be 2 bits or less.

[0057] PUCCH format 1 (PUCCH Format 1) may be a Long PUCCH consisting of four or more symbols and 14 or less symbols. PUCCH format 1 may have the capacity to multiplex up to 84 terminal devices 200 in the same PRB without frequency hopping. PUCCH format 1 may have the capacity to multiplex up to 36 terminal devices 200 in the same PRB with frequency hopping. The UCI transmitted in PUCCH format 1 may be 2 bits or less.

[0058] PUCCH format 2 may be a short PUCCH consisting of one or two symbols. PUCCH format 2 does not require multiplexing between terminal devices 200 in the same PRB. UCI transmitted in PUCCH format 2 may be more than two bits (or three or more bits).

[0059] PUCCH format 3 may be a long PUCCH consisting of four or more symbols and 14 or less symbols. PUCCH format 3 does not require multiplexing between terminal devices 200 in the same PRB. UCI transmitted in PUCCH format 3 may be more than two bits (or three or more bits).

[0060] PUCCH format 4 may be a long PUCCH consisting of four or more symbols and 14 or less symbols. PUCCH format 4 may have the capacity to multiplex up to four terminal devices 200 in the same PRB. UCI transmitted in PUCCH format 4 may be more than two bits (or three or more bits).

[0061] A Short PUCCH format with up to 2 UCI bits may be based on sequence selection. In a Short PUCCH format with more than 2 UCI bits, UCI and DMRS may be frequency multiplexed. In a Long PUCCH format, UCI and DMRS may be time multiplexed. Frequency hopping may be supported in the Long PUCCH format and the Short PUCCH format with a length of 2 symbols. The Long PUCCH format may be repeatedly transmitted across multiple slots.

[0062] In TDD, the base station apparatus 100 may determine a slot format. In TDD, the base station apparatus 100 may transmit slot format configuration information to the terminal apparatus 200. The terminal apparatus 200 may determine a slot format based on the slot format configuration information. The base station apparatus 100 may know the slot format of the terminal apparatus 200 in a cell included in the base station apparatus 100. The slot format configuration information may be one or more higher layer parameters or one or more physical layer signals.

[0063] When slot format configuration information tdd-UL-DL-ConfigurationCommon is provided to the terminal device 200, the terminal device 200 sets a slot format for each slot in a plurality of slots according to the instruction of the slot format configuration information. Setting the slot format may be determining the slot format. The slot format configuration information tdd-UL-DL-ConfigurationCommon may be an upper layer parameter.

[0064] The slot format configuration information tdd-UL-DL-ConfigurationCommon is the reference SCS μ ｒｅｆ (reference SCS Configuration) and pattern 1 are provided. ｒｅｆ may be an integer equal to or greater than 0. Pattern 1 includes a parameter dl-UL-TransmissionPeriodicity that sets the slot configuration period P milliseconds (msec), the number of downlink slots d ｓｌｏｔｓ The parameter nrofDownlinkSlots, which sets the number of downlink symbols d ｓｙｍ The parameter nrofDownlinkSymbols that sets the number of uplink slots u ｓｌｏｔｓ The parameter nrofUplinkSlots, which sets the number of uplink symbols u ｓｙｍ A parameter nrofUplinkSymbols may be provided that sets the milliseconds.

[0065] The slot configuration period P milliseconds is ｒｅｆ In this case, S = P x 2 μｒｅｆ For example, if P is 2.5 and μ ｒｅｆ If d is 1, 5 slots (i.e., S=5) may be included in 2.5 milliseconds. In the S slots, the first d ｓｌｏｔｓ This slot may be only a downlink slot. ｓｌｏｔｓ These slots may be uplink slots only. ｓｌｏｔｓThis slot may be an earlier slot in the S slots. ｓｌｏｔｓ This slot may be a later slot in time sequence, i.e., the first d ｓｌｏｔｓ The slots are the last u ｓｌｏｔｓ The first d slot may be a slot that is earlier in time sequence than the first d slot. ｓｌｏｔｓ d after slots ｓｙｍ These symbols may be downlink symbols. ｓｌｏｔｓ u before slots ｓｙｍ The symbols may be uplink symbols. ｓｙｍ The symbols may be flexible symbols, where f ｓｙｍ = (S-d ｓｌｏｔｓ -u ｓｌｏｔｓ ) x N Ｓｙｍｂ ｓｌｏｔ -d ｓｙｍ -u ｓｙｍ That is, in the S slots, d ｓｌｏｔｓ , d ｓｙｍ , f ｓｙｍ , u ｓｙｍ , u ｓｌｏｔｓ The order may be:

[0066] The downlink slot may include a downlink symbol, the uplink slot may include an uplink symbol, and the first symbol of every 20 / P period may be the first symbol of an even frame.

[0067] When the slot format configuration information tdd-UL-DL-ConfigurationCommon provides pattern 1 and pattern 2, the terminal device 200 may set a slot format for each slot on a first number of slots indicated by pattern 1, and may set a slot format for each slot on a second number of slots indicated by pattern 2.

[0070] In a downlink slot and / or a downlink symbol, the terminal device 200 may receive a downlink channel and / or a downlink signal. For example, the terminal device 200 may receive a PDSCH, a PDCCH, a PBCH, a CSI-RS, or an SSB in a downlink slot and / or a downlink symbol. In an uplink slot and / or an uplink symbol, the terminal device 200 may receive an uplink channel and / or an uplink signal. For example, the terminal device 200 may transmit a PUSCH, a PUCCH, a PRACH, or an SRS in an uplink slot and / or an uplink symbol. In a flexible slot and / or a flexible symbol, the terminal device 200 may receive a downlink channel or a downlink signal scheduled in a DCI format. In a flexible slot and / or a flexible symbol, the terminal device 200 may transmit an uplink channel or an uplink signal scheduled in a DCI format. The terminal device 200 may transmit the PRACH in a flexible slot and / or a flexible symbol.

[0071] If the terminal device 200 is not configured to monitor the PDCCH of DCI format 2_0 in a set of slot symbols indicated as flexible by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, or if tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not provided to the terminal device 200, the terminal device 200 may receive a PDSCH or CSI-RS in the set of slot symbols if the terminal device 200 receives a corresponding instruction in the DCI format.

[0072] If the terminal device 200 is not configured to monitor the PDCCH of DCI format 2_0 in a set of symbols of a slot indicated as flexible by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, or if tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not provided to the terminal device 200, the terminal device 200 may transmit a PUSCH, a PUCCH, a PRACH, or an SRS in the set of symbols of a slot if the terminal device 200 receives a corresponding instruction by a DCI format, or an RAR UL grant, a fallbackRAR UL grant, or a successRAR.

[0073] A terminal device 200 configured to operate in a bandwidth part (BWP) of a serving cell may have a set of up to four BWPs configured by the upper layer of the serving cell. The set of BWPs may include an uplink BWP (UL BWP) and a downlink BWP (DL BWP). The DL BWP may be used by the terminal device 200 for reception in the downlink bandwidth. The DL BWP may be configured based on the upper layer parameter BWP-Downlink, or may be configured based on the upper layer parameter initialDownlinkBWP using a parameter set configured by the upper layer parameter BWP-DownlinkCommon and the upper layer parameter BWP-DownlinkDedicated. The UL BWP may be used for transmission in the uplink bandwidth by the terminal device 200. The UL BWP may be configured based on the upper layer parameter BWP-Uplink, or may be configured based on the upper layer parameter initialUplinkBWP using a set of parameters configured by the upper layer parameter BWP-UplinkCommon and the upper layer parameter BWP-UplinkDedicated.

[0074] If the higher layer parameter initialDownlinkBWP is not provided to the terminal device 200, the initial DL BWP may be set according to the position and number of consecutive PRBs starting from the PRB with the lowest index among the PRBs of the CORESET for the Type0-PDCCH CSS set and ending with the PRB with the highest index. If the higher layer parameter initialDownlinkBWP is not provided to the terminal device 200, the bandwidth of the initial DL BWP may be the same as the bandwidth of the CORESET in which the Type0-PDCCH CSS set is configured. When the higher layer parameter initialDownlinkBWP is not provided to the terminal device 200, the SCS of the Initial DL BWP and the Cyclic Prefix for PDCCH reception may be the same as the SCS and Cyclic Prefix of the CORESET in which the Type0-PDCCH CSS set is configured. When the higher layer parameter initialDownlinkBWP is provided to the terminal device 200, the Initial DL BWP may be provided by the higher layer parameter initialDownlinkBWP. In the case of operation in a primary cell or a secondary cell, the terminal device 200 may be provided with the Initial UL BWP by the InitialUplinkBWP. When a supplementary UL carrier is configured in the terminal device 200, the terminal device 200 may be provided with an initial UL BWP on the supplementary UL carrier by the initial uplink BWP.

[0075] The terminal device 200 may transmit an uplink channel and / or an uplink signal in a UL BWP. The terminal device 200 may receive a downlink channel and / or a downlink signal in a DL BWP.

[0076] In SBFD (Subband Full Duplex), transmission and reception may be performed simultaneously at the same time (Same Time Instance) in a base station device. For example, a base station device 100 that supports SBFD can simultaneously transmit a PDSCH and receive a PUSCH in the same slot. When SBFD is configured in a certain terminal device 200, the terminal device 200 does not need to simultaneously transmit an uplink and receive a downlink. For example, a terminal device 200 configured with SBFD does not simultaneously transmit a PUSCH and a PDSCH in the same time.

[0077] When SBFD is configured in the terminal device 200, it may be configured in one or more component carriers (CCs).

[0078] SBFD may allocate some or all of the configurable frequency resources on a downlink symbol to the uplink. SBFD may allocate some or all of the configurable frequency resources on a flexible symbol to the uplink. The downlink symbol, or the frequency resources allocated to the uplink, including some or all of the configurable frequency resources on the flexible symbol, may be referred to as an UL subband. The UL subband may be an uplink subband. The UL subband may be an uplink subband. The terminal device 200 may transmit an uplink channel or an uplink signal on the UL subband. For example, the terminal device 200 may transmit a PUCCH on the UL subband. For example, the terminal device 200 may transmit a PUSCH on the UL subband. For example, the terminal device 200 may transmit the PRACH on the UL subband. For example, the terminal device 200 may transmit the SRS on the UL subband.

[0079] The SBFD symbol may be a symbol in which a UL subband is configured, or may be a slot including a symbol in which a UL subband is configured.

[0080] The base station device 100 may provide UL subband configuration information to the terminal device 200. The UL subband configuration information may include some or all of the starting PRB index of the UL subband, the bandwidth of the UL subband, the symbol index in which the UL subband is configured, and the slot index in which the UL subband is configured.

[0081] The period of the SBFD symbol configuration in the time domain may be the same as the period P included in the slot format configuration information. When pattern 2 is provided to the terminal device 200, the period of the SBFD symbol configuration in the time domain may be the period P included in the slot format configuration information and the period P ２ Within the period of the SBFD symbol configuration in the time domain, the base station apparatus 100 may provide information on the time resources in which the SBFD symbols are configured to the terminal apparatus 200 using the higher layer parameter SBFDTimeResourceIndication. The base station apparatus 100 may provide information on the time resources in which the SBFD symbols are configured to the terminal apparatus 200 using DCI. The terminal apparatus 200 may configure the SBFD symbols based on the information on the time resources in which the SBFD symbols are configured.

[0082] 6 is a diagram showing an example of a method for configuring a UL subband in this embodiment. The period 801 may be a period indicated by the upper layer parameter dl-UL-TransmissionPeriodicity. For example, the period 801 is P milliseconds. For example, the period 801 is P+P ２ For example, the period 801 is P ２The period 801 may be milliseconds. The period 801 may include a downlink slot 802, a downlink slot 803, a downlink slot 804, a flexible slot 805, and an uplink slot 806. The base station device 100 may provide a start timing 810 and an end timing 811 of the UL subband 800 in the time domain to the terminal device 200. The start timing 810 may be the first symbol included in the slot 803. The start timing 810 may be any symbol included in the downlink slot 803. The end timing 811 may be the last symbol included in the flexible slot 805. The end timing 811 may be any symbol included in the flexible slot 805. The symbols included in downlink slot 803 overlapping with UL subband 800, the symbols included in downlink slot 804 overlapping with UL subband 800, and the symbols included in flexible slot 805 overlapping with UL subband 800 may be SBFD symbols.

[0083] Bandwidth 808 is the bandwidth of UL subband 800. The sum of bandwidth 807, bandwidth 808, and bandwidth 809 may be the bandwidth of DL BWP. In the SBFD symbol, the bandwidth corresponding to bandwidth 807 may be the DL subband. In the SBFD symbol, the bandwidth corresponding to bandwidth 809 may be the DL subband. The DL subband may include a guard band.

[0084] The positions of frequency resources of uplink channels and / or uplink signals may be determined based on the UL BWP. For example, the positions of frequency resources of uplink channels and / or uplink signals may be determined based on the starting PRB of the UL BWP. Alternatively, the positions of frequency resources of uplink channels and / or uplink signals may be determined based on the last PRB of the UL BWP. However, because the positions of frequency resources of uplink channels and / or uplink signals transmitted on the UL subband are determined based on the UL BWP, the frequency resources of uplink channels and / or uplink signals may not be located in the UL subband of the SBFD symbol. If the frequency resources of uplink channels and / or uplink signals are not located in the UL subband of the SBFD symbol, the terminal device 200 may not be able to transmit the uplink channels and / or uplink signals in the SBFD symbol.

[0085] When a frequency resource of an uplink channel and / or an uplink signal is not located in the UL subband on the SBFD symbol, the base station apparatus 100 may provide an offset to the terminal apparatus 200 so that the frequency resource of the uplink channel and / or the uplink signal can be configured on the UL subband. In this first embodiment, the offset may be referred to as an SBFD offset. When the terminal apparatus 200 receives the SBFD offset, the terminal apparatus 200 may apply the SBFD offset to resources corresponding to the uplink channel and / or the uplink signal based on resources of the UL BWP. When the terminal apparatus 200 receives the SBFD offset, the terminal apparatus 200 may apply the SBFD offset to resources corresponding to the uplink channel and / or the uplink signal based on a starting PRB index of the UL BWP. When the terminal device 200 receives the SBFD Offset, the terminal device 200 may apply the SBFD Offset to resources corresponding to uplink channels and / or uplink signals based on the last PRB index of the UL BWP. When the terminal device 200 receives the SBFD Offset, the terminal device 200 may apply the SBFD Offset to resources corresponding to uplink channels and / or uplink signals based on Point A. When the terminal device 200 receives the SBFD Offset, the terminal device 200 may apply the SBFD Offset to resources corresponding to uplink channels and / or uplink signals based on another Offset.

[0086] If the terminal device 200 does not have a dedicated PUCCH resource configuration provided by the PUCCH-ResourceSet included in the higher layer parameter PUCCH-Config, a PUCCH resource set corresponding to an index indicated by the higher layer parameter pucch-ResourceCommon may be provided from a PUCCH resource set table. One PUCCH resource set may include 16 PUCCH resources. The PUCCH resource set may correspond to a PUCCH format, a first symbol, a duration, a PRB offset, and a cyclic shift index set for PUCCH transmission. The terminal device 200 may transmit the PUCCH using frequency hopping. If the terminal device 200 does not have a dedicated PUCCH resource configuration provided by a PUCCH-ResourceSet included in the higher layer parameter PUCCH-Config, an orthogonal cover code (OCC) with index 0 may be applied to PUCCH format 1. If the terminal device 200 does not have a dedicated PUCCH resource configuration provided by a PUCCH-ResourceSet included in the higher layer parameter PUCCH-Config, the terminal device 200 may transmit the PUCCH using the same spatial domain transmission filter as the PUSCH transmission scheduled by the RAR UL grant.

[0087] 7 is a diagram showing an example of a PUCCH resource set table when the terminal device 200 does not have a dedicated PUCCH resource configuration in this embodiment. The indexes included in the table may be PUCCH resource set indexes. The PUCCH resource set indexes may be indicated by the higher layer parameter pucch-ResourceCommon. For example, if the higher layer parameter pucch-ResourceCommon indicates PUCCH resource set index 0, the PUCCH resources included in the PUCCH resource set with index 0 may have a PUCCH format of 0, a starting symbol index of 12, a PUCCH symbol length of 2 symbols, a PRB offset of 0, and an Initial Cyclic Shift set of 0 and 3.

[0088] If the terminal device 200 is not provided with the higher layer parameter pdsch-HARQ-ACK-Codebook, the terminal device 200 may generate HARQ-ACK information of up to 1 bit. If the terminal device 200 provides HARQ-ACK information for detecting DCI format 1_0, DCI format 1_1, or DCI format 1_2 in PUCCH transmission, the terminal device 200 may generate HARQ-ACK information of up to 1 bit. ＰＵＣＣＨ The PUCCH resource may be determined using r ＰＵＣＣＨ r may be a natural number in the range of 0 to 15, inclusive, and may be an integer. ＰＵＣＣＨ may be derived using Equation 1, where N ＣＣＥ n may be the number of CCEs included in the CORESET in which the PDCCH including DCI format 1_0, DCI format 1_1, or DCI format 1_2 is received. ＣＣＥ、０ may be the index of the first CCE in which the PDCCH is received. ＰＲＩ may be a PUCCH Resource Indicator included in DCI format 1_0, DCI format 1_1, or DCI format 1_2. Formula 1

[0089]

[0090] floor (r ＰＵＣＣＨ / 8) is 0, the terminal device 200 sets the PRB index of the PUCCH transmission in the first hop to RB ＢＷＰ ｏｆｆｓｅｔ + floor (r ＰＵＣＣＨ / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 0, the PRB index of the PUCCH transmission in the second hop is N ＢＷＰ ｓｉｚｅ -1-RB ＢＷＰ ｏｆｆｓｅｔ -floor(r ＰＵＣＣＨ / N ＣＳ ) where N ＣＳ may be the total number of initial Cyclic Shift indexes in the set of initial Cyclic Shift indexes. ＰＵＣＣＨ / 8) is 0, the terminal device 200 modulates the initial Cyclic Shift index in the set of initial Cyclic Shift indexes mod(r ＰＵＣＣＨ , N ＣＳ ) may be determined by N ＢＷＰ ｓｉｚｅ may be the size of the uplink BWP (UL BWP).

[0091] Floor(x) may be the largest integer less than or equal to a given real number x. For example, floor(1.2) is 1. For example, floor(2.0) is 2. Mod(A, B) is a remainder function, which may output the remainder when A is divided by B. For example, 3 mod 2 is 1. For example, 4 mod 2 is 0.

[0092] floor (r ＰＵＣＣＨ / 8) is 1, the terminal device 200 sets the PRB index of the PUCCH transmission in the first hop to N ＢＷＰ ｓｉｚｅ -1-RB ＢＷＰ ｏｆｆｓｅｔ-floor((r ＰＵＣＣＨ -8) / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the PRB index of the PUCCH transmission in the second hop is RB ＢＷＰ ｏｆｆｓｅｔ + floor ((r ＰＵＣＣＨ -8) / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the terminal device 200 calculates the initial Cyclic Shift index in the set of initial Cyclic Shift indexes mod(r ＰＵＣＣＨ -8, N ＣＳ ) may be determined.

[0093] FIG. 8 shows an example of a resource grid in which UL subbands are configured in this embodiment. The horizontal axis represents the time axis, and the vertical axis represents the frequency axis. It is assumed that UL subbands are configured from PRB10 to PRB21 in all symbols included in slot 1000 (slot1000). It is assumed that DL subbands are configured from PRB0 to PRB9 and from PRB22 to PRB31 in all symbols included in slot 1000 (slot1000). In other words, all symbols included in slot 1000 may be SBFD symbols. It is also assumed that slot 1000 is determined as a downlink slot by the higher layer parameter tdd-UL-DL-ConfigurationCommon. It is assumed that slot 1001 is determined as an uplink slot by the upper layer parameter tdd-UL-DL-ConfigurationCommon.

[0094] An example will be described in which the terminal device 200 transmits the PUCCH in slot 1001. ＰＵＣＣＨ Assume that is 7. Also, UL BWP size (N ＢＷＰ ｓｉｚｅ) is assumed to be 32 PRBs. The base station apparatus 100 indicates index 0 of the PUCCH resource set to the terminal apparatus 200 using, for example, the higher layer parameter pucch-ResourceCommon. The terminal apparatus 200 selects, for example, a PUCCH resource set with index 0 from the PUCCH resource set table shown in FIG. 7. The terminal apparatus 200 selects, for example, r ＰＵＣＣＨ The PUCCH resource is determined using the above formula. The PRB index of the first hop may be 3. The PRB index of the second hop may be 28. The Initial Cyclic Shift index may be 1. As a result, the PUCCH resource determined by the terminal device 200 may be set as {PUCCH resource start symbol: 12, PUCCH resource length: 2, first hop PRB index: 3, second hop PRB index: 28}. That is, when frequency hopping is performed, the terminal device 200 may transmit the PUCCH on PRB3 included in the 13th symbol and PRB28 included in the 14th symbol in slot 1001. When frequency hopping is not performed, the terminal device 200 may transmit the PUCCH on PRB3 included in the 13th symbol and the 14th symbol in slot 1001.

[0095] An example will be described in which the terminal device 200 transmits the PUCCH in slot 1000. ＰＵＣＣＨ Assume that is 7. Also, UL BWP size (N ＢＷＰ ｓｉｚｅ ) is assumed to be 32 PRBs. The base station apparatus 100 indicates index 0 of the PUCCH resource set to the terminal apparatus 200 using, for example, the higher layer parameter pucch-ResourceCommon. The terminal apparatus 200 selects, for example, a PUCCH resource set with index 0 from the PUCCH resource set table shown in FIG. 7. The terminal apparatus 200 selects, for example, r ＰＵＣＣＨThe PUCCH resource is determined using the PRB index of the first hop. The PRB index of the second hop may be 3. The PRB index of the second hop may be 28. The Initial Cyclic Shift index may be 1. As a result, the PUCCH resource determined by the terminal device 200 is set as, for example, {PUCCH resource start symbol: 12, PUCCH resource length: 2, first hop PRB index: 3, second hop PRB index: 28}. However, in slot 1000, since PRB3 and PRB28 are included in the DL subband, an offset may be applied so that the PUCCH resource is located on the UL subband. Here, the offset applied to the first hop PRB index is set as the RB index. ＵＬｓｕｂ offset, first, and the offset to be applied to the PRB index of the second hop ＵＬｓｕｂ The offset RB applied to the first hop is called offset and second hop. ＵＬｓｕｂ offset, first, and offset RB applied to second hop ＵＬｓｕｂ The offset and second may be different values ​​or may be the same value. ＰＵＣＣＨ / 8) is 0, the terminal device 200 sets the PRB index of the PUCCH transmission in the first hop to RB ＢＷＰ ｏｆｆｓｅｔ +RB ＵＬｓｕｂ offset, first+floor(r ＰＵＣＣＨ / N ＣＳ ) may be determined. ＰＵＣＣＨ / 8) is 0, the terminal device 200 sets the PRB index of the PUCCH transmission in the second hop to N ＢＷＰ ｓｉｚｅ -1-RB ＢＷＰ ｏｆｆｓｅｔ -RB ＵＬｓｕｂ offset, second-floor(r ＰＵＣＣＨ / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the terminal device 200 sets the PRB index of the PUCCH transmission in the first hop to N ＢＷＰ ｓｉｚｅ -1-RB ＢＷＰ ｏｆｆｓｅｔ -RB ＵＬｓｕｂ offset, first-floor((r ＰＵＣＣＨ -8) / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the PRB index of the PUCCH transmission in the second hop is set to RB ＢＷＰ ｏｆｆｓｅｔ +RB ＵＬｓｕｂ offset, second+floor((r ＰＵＣＣＨ -8) / N ＣＳ ) may be determined by N ＢＷＰ ｓｉｚｅ N may be the number of PRBs in the UL BWP. ＢＷＰ ｓｉｚｅ Returning to the example of PUCCH transmission in slot 1000, the terminal device 200 may set an integer between 7 and 18 as the number of PRBs in the DL BWP. ＵＬｓｕｂ offset, first, and add it to the PRB index of the first hop determined in advance to determine a new PRB index. ＵＬｓｕｂ A new PRB index may be determined by subtracting the offset, second, from the PRB index of the predetermined second hop.

[0096] Here, a flow up to when a terminal in which SBFD is set transmits data will be described in embodiment 1. Fig. 9 is a sequence diagram of the wireless communication system 1 in this embodiment.

[0097] The transmitter 111 of the base station device 100 transmits a first signal including first information regarding SBFD configuration and second information regarding the configuration of an uplink channel to the terminal device 200 (step S10). Note that the first information regarding SBFD configuration may also be referred to as first information configuring a UL subband. The first information and the second information may be transmitted by different signals. Note that the first signal is, for example, a signal of a higher layer or a signal of an RRC layer. The second information regarding the configuration of an uplink channel may be, for example, information regarding the configuration of an uplink control channel or information regarding the configuration of a random access channel.

[0098] The control unit 220 of the terminal device 200 performs a first process of setting SBFD in accordance with information related to the setting of SBFD (step S20). When setting SBFD, the control unit 220 of the terminal device 200 adjusts the uplink resources to be located on the uplink subband, for example, by using an offset value. Details of the offset value will be described later.

[0099] The transmitter 211 of the terminal device 200 transmits an uplink signal on the uplink subband set by the first process (step S30).

[0100] 9, a signal indicating the completion may be transmitted after the SBFD configuration is completed. Furthermore, if the uplink signal transmitted in step S30 includes data, the receiving unit 212 of the terminal device 200 may receive a reception confirmation response to the uplink signal. Furthermore, before the transmission in step S30, a downlink signal may be received, and a response signal to the downlink signal (e.g., a PUCCH including information related to HARQ) may be transmitted as the third signal.

[0101] Here, the offset value will be explained.

[0102] A first example of the offset value will be described. In the first example, the base station device 100 notifies the terminal device 200 of the offset value. The base station device 100 notifies the terminal device 200 of the first hop PRB index and / or the second hop PRB index determined by the terminal device 200 of the first offset RB index. ＵＬｓｕｂ Offset, first and RB ＵＬｓｕｂ The first hop PRB index and / or the second hop PRB index may be provided to the terminal device 200. The first offset may be provided via a higher layer parameter. In short, the first signal is transmitted including third information related to the first offset. The first offset is, for example, a value used to adjust the first hop PRB index and / or the second hop PRB index so that they are included in the UL subband. Note that the third information may be included in the first information.

[0103] Next, a second example of the offset value will be described. In the second example, the terminal device 200 determines the offset value from the SBFD setting. The terminal device 200 determines the second offset RB ＵＬｓｕｂ Offset, first and RB ＵＬｓｕｂ The second offset is, for example, a value for adjusting the PRB index of the first hop and / or the PRB index of the second hop so that they are included in the UL subband. For example, the terminal device 200 may determine the second offset using the starting PRB index of the UL subband and the starting PRB index of the UL BWP. For example, the terminal device 200 may determine the second offset RB to be applied to the first hop based on the difference between the starting PRB index of the UL subband and the starting PRB index of the UL BWP. ＵＬｓｕｂ For example, the terminal device 200 may determine a second offset RB to be applied to the first hop based on the difference between the start PRB index of the UL subband and the start PRB index of the DL BWP. ＵＬｓｕｂFor example, the terminal device 200 may determine the second offset RB to be applied to the second hop based on the difference between the last PRB index of the UL subband and the last PRB index of the UL BWP. ＵＬｓｕｂ For example, the terminal device 200 may determine the second offset RB to be applied to the second hop based on the difference between the last PRB index of the UL subband and the last PRB index of the DL BWP. ＵＬｓｕｂ The offset and second can be determined.

[0104] Next, a third example of the offset value will be described. The third example is an example of determining the PRB index of the PUCCH resource in slot 1000. ＰＵＣＣＨ / 8) is 0, the terminal device 200 sets the PRB index of the PUCCH transmission in the first hop to RB ＢＷＰ ｏｆｆｓｅｔ +n ＵＬｓｕｂ Ｓｔａｒｔ + floor (r ＰＵＣＣＨ / N ＣＳ ) where n ＵＬｓｕｂ Ｓｔａｒｔ may be the starting PRB index of the UL subband. ＰＵＣＣＨ / 8) is 0, the PRB index of the PUCCH transmission in the second hop is N ＵＬｓｕｂ ｓｉｚｅ +n ＵＬｓｕｂ Ｓｔａｒｔ -1-RB ＢＷＰ ｏｆｆｓｅｔ -floor(r ＰＵＣＣＨ / N ＣＳ ) where N ＵＬｓｕｂ ｓｉｚｅ may be the number of PRBs in the bandwidth of the UL subband. ＰＵＣＣＨ / 8) is 0, the terminal device 200 modulates the initial Cyclic Shift index in the set of initial Cyclic Shift indexes mod(r ＰＵＣＣＨ , NＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the terminal device 200 sets the PRB index of the PUCCH transmission in the first hop to N ＵＬｓｕｂ ｓｉｚｅ +n ＵＬｓｕｂ Ｓｔａｒｔ -1-RB ＢＷＰ ｏｆｆｓｅｔ -floor((r ＰＵＣＣＨ -8) / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the PRB index of the PUCCH transmission in the second hop is RB ＢＷＰ ｏｆｆｓｅｔ +n ＵＬｓｕｂ Ｓｔａｒｔ + floor ((r ＰＵＣＣＨ -8) / N ＣＳ ) may be determined by floor(r ＰＵＣＣＨ / 8) is 1, the terminal device 200 calculates the initial Cyclic Shift index in the set of initial Cyclic Shift indexes mod(r ＰＵＣＣＨ -8, N ＣＳ ) may be determined.

[0105] Next, a method of adjusting the UL subband without using an offset value will be described. For example, the base station apparatus 100 sets the size of the UL BWP to be set in the terminal apparatus 200 to be equal to or smaller than the size of the UL subband. Note that information on the sizes of the UL subband and the UL BWP is transmitted, for example, in a first signal. The base station apparatus 100 may set the size of the UL subband to be equal to the size of the UL BWP. When the size of the UL subband is equal to or larger than the size of the UL BWP, the starting PRB index of the first hop and / or second hop may be determined based on the size of the UL BWP. If the size of the UL subband is smaller than the size of the UL BWP, the starting PRB index of the first hop and / or second hop may be determined based on the size of the UL subband.

[0106] Next, an example of control of the terminal device 200 when the terminal device 200 does not have a dedicated PUCCH resource configuration will be described. When the terminal device 200 does not have a dedicated PUCCH resource configuration, the terminal device 200 controls so as not to transmit the PUCCH in symbols in which SBFD symbols are set. Furthermore, when the terminal device 200 does not have a dedicated PUCCH resource configuration, the terminal device 200 controls so as to transmit the PUCCH in symbols in which SBFD symbols are not set. For example, the terminal device 200 does not need to be expected to transmit the PUCCH in slot 1000. For example, the terminal device 200 may be expected to transmit the PUCCH in slot 1001. By doing this, for example, on the UL subband, only assigned uplink signals are transmitted using, for example, downlink control information. Therefore, resources for transmitting the PUCCH are not located on the DL subband. Note that the downlink control information may instruct transmission of the PUCCH in uplink-only slots. This example can be used in combination with the above-mentioned examples using and not using offsets.

[0107] Next, a method for controlling the position of an RO (RACH Occasion) will be described. In this example, the first signal transmitted in step S10 of FIG. 9 is, for example, a higher layer signal such as SIB1, and includes various higher layer parameters. The first process performed in step S20 of FIG. 9 is a process for adjusting the RO so that it is located on the UL subband. The second signal transmitted in step S30 of FIG. 9 is, for example, a random access signal (e.g., MSGA or MSG1). When the RO is configured on a UL symbol other than an SBFD symbol, the frequency domain position of the RO may be determined by the higher layer parameter msg1-FrequencyStart. The higher layer parameter msg1-FrequencyStart may be an offset from the start PRB index of the UL BWP. When the RO is configured on the UL subband included in the SBFD symbol, the frequency domain position of the RO may be determined by the upper layer parameter msg1-FrequencyStart and the upper layer parameter msg1-SBFDFrequenceStart. The upper layer parameter msg1-SBFDFrequenceStart may be an offset from the starting PRB index of the UL BWP. The upper layer parameter msg1-SBFDFrequenceStart may be an offset from the PRB index determined by the upper layer parameter msg1-FrequencyStart.

[0108] Next, in a flexible symbol and / or a flexible slot, when the terminal device 200 has configuration information for uplink transmission in an SBFD symbol and configuration information for uplink signals in symbols that are not SBFD symbols (non-SBFD symbols), the terminal device 200 may apply only the configuration information for uplink transmission in the SBFD symbol. The configuration information for uplink transmission may be information carried in higher layer parameters and / or DCI for transmission of an uplink channel and / or an uplink signal.

[0109] In a flexible symbol and / or flexible slot, when the terminal device 200 has configuration information for uplink transmission in an SBFD symbol and configuration information for uplink signals in symbols that are not SBFD symbols (non-SBFD symbols), the terminal device 200 may apply only the configuration information for uplink transmission in symbols that are not SBFD symbols.

[0110] In a flexible symbol and / or flexible slot, when the terminal device 200 has configuration information for uplink transmission in an SBFD symbol and configuration information for uplink signals in symbols that are not SBFD symbols (non-SBFD symbols), the terminal device 200 may apply the configuration information for uplink transmission in an SBFD symbol and the configuration information for uplink transmission in symbols that are not SBFD symbols.

[0111] Next, in a flexible symbol and / or a flexible slot, when the terminal device 200 has configuration information for downlink transmission in an SBFD symbol and configuration information for downlink signals in symbols other than the SBFD symbol (non-SBFD symbol), the terminal device 200 may apply only the configuration information for downlink transmission in the SBFD symbol. The configuration information for downlink transmission may be information carried in a downlink channel and / or higher layer parameters for transmission of the downlink signal and / or DCI.
