Description

[Technical Field]

[0001] The present disclosure relates to a terminal and a communication method. [Background technology]

[0002] Long Term Evolution (LTE) has been specified for Universal Mobile Telecommunication System (UMTS) networks to achieve higher data rates and lower latency. Furthermore, successor systems to LTE are also being considered to achieve even greater bandwidth and speed than LTE. Examples of successor systems to LTE include LTE-Advanced (LTE-A), Future Radio Access (FRA), 5th generation mobile communication system (5G), 5G plus (5G+), Radio Access Technology (New-RAT), and New Radio (NR).

[0003] In 3GPP Rel. 17, methods called Ultra-Reliable and Low Latency Communications (URLLC) and Industrial Internet of Things (IIoT) were studied, and several technologies were approved (see, for example, Non-Patent Document 1). For example, in Rel. 17, based on the work in Rel. 16 (RAN1), technologies related to intra-UE multiplexing of traffic with different priorities and intra-UE prioritization were approved (specified).

[0004] For example, multiplexing operations between HARQ-ACK / SR / CSI and PUSCH for traffic with different priorities, including the case of UCI for PUCCH and UCI for PUSCH, have been identified.

[0005] Also, based on the solution considered in Rel. 16, PHY prioritization for overlapping dynamic grant PUSCH (DG PUSCH) and configured grant PUSCH (CG PUSCH) is specified. The DG PUSCH and CG PUSCH may have different PHY priorities in the BWP of the serving cell, and the serving cell may have related cancellation behavior for PUSCHs with lower physical priorities.

[0006] Note that RAN is an abbreviation for Radio Access Network. PUCCH is an abbreviation for Physical Uplink Control Channel. PUSCH is an abbreviation for Physical Uplink Shared Channel. UCI is an abbreviation for Uplink Control Information. HARQ-ACK is an abbreviation for Hybrid Automatic Repeat request - Acknowledgement. SR is an abbreviation for Scheduling Request. CSI is an abbreviation for Channel State Information. BWP is an abbreviation for Band Width Part. [Prior art documents] [Non-patent literature]

[0015] Hereinafter, an embodiment according to one aspect of the present disclosure will be described with reference to the drawings.

[0016] <Overall schematic configuration of wireless communication system> Fig. 1 is a diagram showing an overall schematic configuration of a wireless communication system 10 according to an embodiment. As shown in Fig. 1, the wireless communication system 10 includes a base station 100, a terminal 200, and a wireless access network 20. The wireless communication system 10 may be a wireless communication system conforming to a standard called 5G, Beyond 5G, 5G Evolution, or 6G.

[0017] The base station 100 may be called an NG-RAN Node, an ng-eNB, an eNodeB (eNB), or a gNodeB (gNB). The terminal 200 may be called User Equipment (UE). The base station 100 may also be considered as a device included in the radio access network 20 to which the terminal 200 is connected.

[0018] The radio access network 20 may include a Next Generation-Radio Access Network (hereinafter, referred to as NG-RAN). The NG-RAN includes multiple NG-RAN nodes, specifically, gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). The NG-RAN and 5GC may be simply referred to as a "network."

[0019] Base station 100 performs wireless communication with terminal 200. For example, the performed wireless communication complies with NR. At least one of base station 100 and terminal 200 may support Massive MIMO (Multiple-Input Multiple-Output), which generates a more directional beam (BM) by controlling radio signals transmitted from multiple antenna elements. Furthermore, at least one of base station 100 and terminal 200 may support Carrier Aggregation (CA), which aggregates and uses multiple component carriers (CC). Furthermore, at least one of base station 100 and terminal 200 may support Dual Connectivity (DC), which performs communication between terminal 200 and each of multiple base stations 100.

[0020] The wireless communication system 10 may support multiple frequency bands. For example, the wireless communication system 10 supports Frequency Range (FR) 1 and FR 2. The frequency bands of each FR are, for example, as follows: FR1: 410MHz~7.125GHz FR2: 24.25GHz~52.6GHz

[0021] FR1 may use a Sub-Carrier Spacing (SCS) of 15 kHz, 30 kHz, or 60 kHz, and may use a bandwidth (BW) of 5 MHz to 100 MHz. FR2 is, for example, a higher frequency than FR1. FR2 may use an SCS of 60 kHz or 120 kHz, and may use a bandwidth (BW) of 50 MHz to 400 MHz. FR2 may also include an SCS of 240 kHz.

[0022] The wireless communication system 10 in this embodiment may support a frequency band higher than the FR2 frequency band. For example, the wireless communication system 10 in this embodiment may support a frequency band exceeding 52.6 GHz up to 114.25 GHz. Such a high frequency band may be called "FR2x."

[0023] Alternatively, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) having a larger SCS than the above-mentioned example may be applied. Furthermore, DFT-S-OFDM may be applied to both the uplink and the downlink, or to either one of them.

[0024] FIG. 2 is a diagram showing an example of the configuration of a radio frame, subframe, and slot used in the radio communication system 10. As shown in FIG. 2, one slot is made up of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). Note that the number of symbols making up one slot does not necessarily have to be 14 symbols. For example, the number of symbols making up one slot may be 28 or 56 symbols. Also, the number of slots per subframe may differ depending on the SCS. Furthermore, the SCS may be wider than 240 kHz.

[0025] 2 may be called a time domain, a symbol period, a symbol time, etc. Furthermore, the frequency direction may be called a frequency domain, a resource block, a subcarrier, a BWP (Bandwidth part), etc.

[0026] In the wireless communication system 10, a plurality of downlink control information (DCI) may be used. DCI may be interpreted as control information transmitted in the downlink that includes scheduling information, data modulation, and information on the channel coding rate necessary for each user equipment (UE) to demodulate data.

[0027] <Agreement content> In 3GPP Rel.17, several technologies were agreed upon regarding intra-UE multiplexing of traffic with different priorities.

[0028] For example, it was agreed to support multiplexing to PUCCH, such as HARQ-ACK with different priorities. Also, it was agreed to support multiplexing to PUSCH, such as HARQ-ACK with different priorities.

[0029] Note that traffic may be read as a channel, data channel, control channel, path, data, or control data, etc. HARQ-ACK is an example of information regarding a confirmation response (e.g., acknowledgement) for data received by the terminal.

[0030] In 3GPP Rel.16, DCI format 2_4 was introduced to ensure high-priority uplink (UL) transmission and cancel low-priority UL transmission (see, for example, Section 7.3.1.3.5 of TS38.212 v16.7.0 and Section 11.2A of TS38.213 v16.7.0).

[0031] DCI format 2_4 may be used to notify a group of terminals of the physical resource blocks (PRBs) and OFDM symbols for which corresponding UL transmissions from the terminals are to be canceled. That is, DCI format 2_4 may be interpreted as a format for notifying the PRBs and OFDM symbols for which UL transmissions are to be canceled. Note that "cancel" may be interpreted as "cancel," "stop," "abort," "drop," or "delete."

[0032] The terminal can cancel UL transmission such as PUSCH or Sounding Reference Signal (SRS) based on UL Cancellation Indication (hereinafter, sometimes referred to as UL CI) indicated by DCI format 2_4. Note that PUCCH may also be canceled by UL CI.

[0033] 3 is a diagram showing an example of an UL CI scheme. UE#1 for eMBB (enhanced Mobile Broadband) receives an UL grant, for example, in the resource indicated by arrow A1. UE#1 that has received the UL grant schedules an UL transmission, for example, in the resource indicated by arrow A2.

[0034] UE#2 for URLLC receives an UL grant, for example, in the resource indicated by arrow A3. Having received the UL grant, UE#2 schedules an UL transmission, for example, in the resource indicated by arrow A4.

[0035] UE#1 is notified of the UL CI based on DCI format 2_4, for example, in the resource indicated by arrow A5. When UE#1 is notified of the UL CI, UE#1 cancels the UL transmission, for example, in the resource indicated by arrow A6 (resource indicated by the UL CI) among the resources indicated by arrow A2 for which UL transmission has been scheduled.

[0036] The above scheme ensures UL transmission for UE#2 for URLLC. For example, UL transmission of the resource indicated by arrow A4 is ensured. In other words, high-priority UL transmission is ensured.

[0037] <Analysis> As mentioned above, in Rel. 17, several technologies were agreed upon regarding intra-terminal multiplexing of traffic (channels) with different priorities.

[0038] However, there is room for further study on the applicability of UL CIs for PUSCHs including both low priority (LP) and high priority (HP) channels. In other words, there is room for further study on the applicability of UL CIs for PUSCHs in which LP channels and HP channels are multiplexed. For example, when LP channels and HP channels are multiplexed in the resource (PUSCH) indicated by arrow A2 in Fig. 3, there is room for further study on the applicability of UL CIs.

[0039] Note that the term "channel" may be interpreted as "signal." Also, the term "channel" may be uplink control information such as UCI, or uplink data such as an Uplink Shared Channel (UL-SCH). For example, both the LP channel and the HP channel may be UCI. The LP channel may be UCI, and the HP channel may be UL-SCH. The LP channel may be UL-SCH, and the HP channel may be UCI. Both the LP channel and the HP channel may be UCI. Also, the UCI may include control information such as HARQ-ACK, SR, and CSI. Also, the term "PUSCH" may be interpreted as an uplink channel or UL transmission.

[0040] <Proposal 1> The UL CI does not need to be applied to a PUSCH that includes channels of different priorities. For example, the UL CI does not need to be applied to a PUSCH that includes both an LP channel and an HP channel. In other words, the terminal does not need to cancel a PUSCH in which the LP channel and the HP channel are multiplexed intra-UE. Specifically, when the terminal (UE#1) multiplexes the LP channel and the HP channel in the resource indicated by arrow A2 in FIG. 3, it does not need to cancel UL transmission in the resource indicated by arrow A6. This operation allows the PUSCH in which the HP channel is multiplexed to be transmitted without being canceled.

[0041] On the other hand, the terminal may cancel a PUSCH including only one priority channel based on the notification of the UL CI in DCI format 2_4. For example, the terminal may cancel a PUSCH including only an LP channel based on the notification of the UL CI in DCI format 2_4. Also, the terminal may cancel a PUSCH including only an HP channel based on the notification of the UL CI in DCI format 2_4.

[0042] Note that the terminal does not need to cancel a PUSCH that includes both the LP channel and the HP channel, regardless of whether or not the UL CI in DCI format 2_4 is notified. In other words, when the PUSCH includes both the LP channel and the HP channel, the terminal does not need to cancel the PUSCH even if the UL CI is notified. This operation forces the PUSCH multiplexed with the HP channel to be transmitted.

[0043] Furthermore, the base station may schedule so that channels of different priorities are not included in one PUSCH (so that the terminal does not intra-terminally multiplex channels of different priorities in one PUSCH). This operation eliminates the need for the terminal to expect notification from the base station regarding cancellation of a PUSCH (UL CI) that includes both the LP channel and the HP channel.

[0044] <Proposal 2> The UL CI may be applied to a PUSCH including channels of different priorities. For example, the UL CI may be applied to a PUSCH including both an LP channel and an HP channel. In other words, the terminal may cancel a PUSCH in which the LP channel and the HP channel are multiplexed within the terminal. Specifically, when the LP channel and the HP channel are multiplexed in the resource indicated by the arrow A2 shown in FIG. 3, the terminal (UE#1) may cancel UL transmission in the resource indicated by the arrow A6.

[0045] The terminal may cancel a PUSCH including both the LP channel and the HP channel, for example, based on notification of a UL CI in DCI format 2_4. That is, the terminal may cancel a PUSCH including both the LP channel and the HP channel based on an instruction from the base station. This operation cancels the transmission of the PUSCH multiplexed with the LP channel. Furthermore, because the transmission of the PUSCH multiplexed with the LP channel is canceled, channels of other terminals that overlap with the PUSCH (for example, URLLC resource signals indicated by arrow A4 in FIG. 3) are properly received by the base station.

[0046] Furthermore, the terminal may cancel a PUSCH that includes a channel of only one priority based on the notification of the UL CI in DCI format 2_4. For example, the terminal may cancel a PUSCH that includes only an LP channel based on the notification of the UL CI in DCI format 2_4. Furthermore, the terminal may cancel a PUSCH that includes only an HP channel based on the notification of the UL CI in DCI format 2_4.

[0047] The terminal may cancel a PUSCH that includes both an LP channel and an HP channel, regardless of whether or not an UL CI is reported in DCI format 2_4. That is, when the PUSCH includes both an LP channel and an HP channel, the terminal may cancel the PUSCH even if an UL CI is not reported. This operation forcibly cancels the transmission of the PUSCH multiplexed with the LP channel.

[0048] <Proposal 3> The terminal may determine the application of UL CI based on parameters of higher layer signaling such as Radio Resource Control (RRC) signaling. In other words, the terminal may determine (switch) the cancellation operation of UL transmission based on parameters of higher layer signaling. This operation allows the terminal's cancellation operation of UL transmission to be flexibly changed.

[0049] Proposal 3 may include the following three options:

[0050] <Option 1> The terminal may determine the application of UL CI to UL transmission based on existing parameters. The existing parameters may be, for example, existing RRC parameters. The existing RRC parameters may be, for example, uplinkCancellationPriority-r16 of CI-ConfigurationPerServingCell (see, for example, Chapter 6.3.2 of TS38.331 v16.7.0, UplinkCancellation information element).

[0051] Fig. 4 is a diagram illustrating an example of Option 1 of Proposal 3. As shown in Fig. 4, application of UL CI may be determined based on the field content of uplinkCancellationPriority-r16.

[0052] For example, as shown in Fig. 4, when information indicating "enabled" is present in the field of uplinkCancellationPriority-r16, the UL CI may be applied only to UL transmissions indicated (set) as a low priority level. In other words, when the parameter field of the received uplinkCancellationPriority-r16 contains information indicating "enabled" and the terminal receives a UL CI, the terminal may cancel UL transmissions including only LP channels.

[0053] On the other hand, as shown in FIG. 4, when the uplinkCancellationPriority-r16 field is "absent" (e.g., no information is present in the field), the UL CI may be applied to UL transmission regardless of the priority level of the channel included in the PUSCH. In other words, when the received uplinkCancellationPriority-r16 parameter field is "absent" and the UE receives a UL CI, the UE may cancel the UL transmission regardless of the priority of the channel. For example, the UE cancels a UL transmission that includes only an LP channel. The UE cancels a UL transmission that includes only an HP channel. The UE cancels a UL transmission that includes both an LP channel and an HP channel.

[0054] <Option 2> The terminal may determine the application of the UL CI to UL transmission based on the new parameter. The new parameter may be, for example, a new RRC parameter. The new RRC parameter may be, for example, uplinkCancellationPriority-r17 of CI-ConfigurationPerServingCell.

[0055] Fig. 5 is a diagram illustrating an example of Option 2 of Proposal 3. As shown in Fig. 5, application of UL CI may be determined based on the field content of uplinkCancellationPriority-r17.

[0056] For example, as shown in Fig. 5, when information indicating "LP" is present in the field of uplinkCancellationPriority-r17, the UL CI may be applied only to UL transmissions indicated (set) as a low priority level. In other words, when the parameter field of the received uplinkCancellationPriority-r17 contains information indicating "LP" and the terminal receives a UL CI, the terminal may cancel UL transmissions including only LP channels.

[0057] For example, as shown in Fig. 5, when information indicating "HP" is present in the field of uplinkCancellationPriority-r17, the UL CI may be applied only to UL transmissions indicated as having a level equal to or lower than the high priority level. In other words, when the parameter field of the received uplinkCancellationPriority-r17 contains information indicating "HP" and the terminal receives a UL CI, the terminal may cancel UL transmissions including channels equal to or lower than the HP channel. In other words, the terminal may cancel UL transmissions including only LP channels and may also cancel UL transmissions including only HP channels.

[0058] For example, as shown in FIG. 5, when the uplinkCancellationPriority-r17 field is "absent," the UL CI may be applied to UL transmission regardless of the priority level of the channel included in the PUSCH. In other words, when the received uplinkCancellationPriority-r17 parameter field is "absent" and the terminal receives a UL CI, the terminal may cancel the UL transmission regardless of the priority of the channel. For example, the terminal cancels a UL transmission that includes only an LP channel. The terminal cancels a UL transmission that includes only an HP channel. The terminal cancels a UL transmission that includes both an LP channel and an HP channel.

[0059] <Option 3> The terminal may determine the application of UL CI to UL transmission based on the existing parameter and the new parameter, where the existing parameter may be, for example, uplinkCancellationPriority-r16 of CI-ConfigurationPerServingCell, and the new parameter may be, for example, uplinkCancellationPriority-r17 of CI-ConfigurationPerServingCell.

[0060] Fig. 6 is a diagram illustrating an example of Option 3 of Proposal 3. As shown in Fig. 6, the application of UL CI may be determined based on a combination of the content of the uplinkCancellationPriority-r16 field (first field) and the content of the uplinkCancellationPriority-r17 field (second field).

[0061] For example, as shown in Fig. 6, when information indicating "enabled" is present in the first and second fields, the UL CI may be applied only to UL transmissions indicated as a low priority level. In other words, when the parameter field of the received uplinkCancellationPriority-r16 includes information indicating "enabled" and the parameter field of the received uplinkCancellationPriority-r17 includes information indicating "enabled", the terminal may cancel UL transmissions including only LP channels when it receives a UL CI.

[0062] For example, as shown in Fig. 6, when the first field is "absent" and the second field contains information indicating "enabled," the UL CI may be applied only to UL transmissions indicated as having a level equal to or lower than the high priority level. In other words, when the parameter field of the received uplinkCancellationPriority-r16 is "absent" and the parameter field of the received uplinkCancellationPriority-r17 contains information indicating "enabled," the terminal may cancel UL transmissions including channels equal to or lower than the HP channel when receiving a UL CI. That is, the terminal may cancel UL transmissions including only the LP channel, and may also cancel UL transmissions including only the HP channel.

[0063] For example, as shown in Fig. 6, when the first field contains information indicating "enabled" and the second field contains "absent," the UL CI may be applied only to UL transmissions indicated as a low priority level. In other words, when the parameter field of the received uplinkCancellationPriority-r16 contains information indicating "enabled," the parameter field of the received uplinkCancellationPriority-r17 contains "absent," and the UE receives a UL CI, the UE may cancel UL transmissions including only LP channels.

[0064] For example, as shown in FIG. 6, if the first and second fields are "absent," the UL CI may be applied to UL transmission regardless of the priority level of the channel included in the PUSCH. In other words, if the parameter field of the received uplinkCancellationPriority-r16 is "absent" and the parameter field of the received uplinkCancellationPriority-r17 is "absent," the UE may cancel UL transmission regardless of the priority of the channel when receiving the UL CI. For example, the UE cancels UL transmission including only the LP channel. The UE cancels UL transmission including only the HP channel. The UE cancels UL transmission including both the LP channel and the HP channel.

[0065] <Terminal Capabilities> The terminal may transmit a terminal capability indicating the terminal's capabilities to a network such as the NG-RAN 20. The terminal may transmit the terminal capability in response to receiving a UE Capability Enquiry from the network.

[0066] The UE capability indicating the capability of the terminal may include the following information indicating the capability of the terminal: Note that the information indicating the capability of the terminal may correspond to information defining the capability of the terminal.

[0067] Information defining whether the terminal supports UL CI applicable to UL channels multiplexed with LP and HP channels based on intra-terminal multiplexing

[0068] The information may include information about which proposal and option applies. For example, the information may include information indicating that proposal 2 or proposal 3 applies.

[0069] Furthermore, if the terminal does not transmit the above terminal capabilities, it may apply Proposal 1. For example, the terminal may not expect notification from the base station regarding cancellation of the PUSCH (UL CI) including both the LP channel and the HP channel.

[0070] <Variations> Although Proposal 3 states that the terminal may determine the UL transmission cancellation operation based on parameters of higher layer signaling such as RRC signaling, this is not limiting. For example, the terminal may determine the UL transmission cancellation operation based on system information such as a Master Information Block (MIB) or a System Information Block (SIB), or lower layer signaling such as DCI. That is, the terminal may determine the UL transmission cancellation operation based on notification of information from a network such as NG-RAN 20.

[0071] The terminal may determine whether to operate in Proposal 1 or Proposal 2 based on the notification of information. That is, the terminal may determine whether to apply cancellation operation of UL transmission including channels with different priorities (channels multiplexed within the terminal) based on the notification of information. Note that "apply" may be read as "enable."

[0072] The channel priorities are not limited to two, the LP channel and the HP channel. In Proposals 1 to 3, the channel priorities may be 3 or higher.

[0073] <Base station configuration> 7 is a block diagram showing an example of the configuration of base station 100 according to the embodiment. Base station 100 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. Base station 100 communicates with terminal 200 (see FIG. 8) by radio.

[0074] The transmitter 101 transmits a downlink (DL) signal to the terminal 200. For example, the transmitter 101 transmits the DL signal under the control of the controller 103.

[0075] The DL signal may include, for example, a downlink data signal and control information (e.g., Downlink Control Information (DCI)). The DL signal may also include information indicating scheduling related to signal transmission of terminal 200 (e.g., an UL grant). The DL signal may also include control information of higher layers (e.g., RRC control information). The DL signal may also include a reference signal.

[0076] Channels used for transmitting DL signals include, for example, data channels and control channels. For example, the data channels may include a PDSCH (Physical Downlink Shared Channel), and the control channels may include a PDCCH (Physical Downlink Control Channel). For example, base station 100 transmits control information to terminal 200 using the PDCCH and transmits downlink data signals using the PDSCH.

[0077] The reference signal included in the DL signal may include at least one of a demodulation reference signal (Demodulation Reference Signal (DMRS)), a Phase Tracking Reference Signal (PTRS), a Channel State Information-Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), and a Positioning Reference Signal (PRS) for position information. For example, reference signals such as DMRS and PTRS are used for demodulating downlink data signals and are transmitted using the PDSCH.

[0078] The receiving unit 102 receives an uplink (UL) signal transmitted from the terminal 200. For example, the receiving unit 102 receives the UL signal under the control of the control unit 103.

[0079] The control unit 103 controls the communication operations of the base station 100, including the transmission processing of the transmission unit 101 and the reception processing of the reception unit .

[0080] For example, the control unit 103 acquires information such as data and control information from the upper layer and outputs it to the transmitting unit 101. The control unit 103 also outputs the data, control information, etc. received from the receiving unit 102 to the upper layer.

[0081] For example, control unit 103 allocates resources (or channels) used for transmitting and receiving DL signals and / or resources used for transmitting and receiving UL signals based on signals (e.g., data and control information, etc.) received from terminal 200 and / or data and control information, etc. acquired from a higher layer. Information related to the allocated resources may be included in control information transmitted to terminal 200.

[0082] Control section 103 configures PUCCH resources as an example of allocation of resources used for transmitting and receiving UL signals. Information relating to PUCCH configuration such as a PUCCH cell timing pattern (PUCCH configuration information) may be reported to terminal 200 by RRC.

[0083] The control unit 103 may schedule a terminal that has not transmitted the above-mentioned terminal capability so that channels of different priorities are not included in one PUSCH (so that the terminal does not intra-terminally multiplex channels of different priorities into one PUSCH).The control unit 103 may schedule a terminal that has transmitted the above-mentioned terminal capability so that channels of different priorities are included in one PUSCH.

[0084] <Device configuration> 8 is a block diagram showing an example of the configuration of terminal 200 according to the embodiment. Terminal 200 includes, for example, receiving unit 201, transmitting unit 202, and control unit 203. Terminal 200 communicates with base station 100, for example, wirelessly.

[0085] The receiving unit 201 receives a DL signal transmitted from the base station 100. For example, the receiving unit 201 receives the DL signal under the control of the control unit 203.

[0086] The transmitter 202 transmits the UL signal to the base station 100. For example, the transmitter 202 transmits the UL signal under the control of the controller 203.

[0087] The UL signal may include, for example, an uplink data signal and control information (e.g., UCI). For example, information related to the processing capability of terminal 200 (e.g., UE capability) may be included. The UL signal may also include a reference signal.

[0088] Channels used for transmitting UL signals include, for example, data channels and control channels. For example, the data channels include a PUSCH (Physical Uplink Shared Channel), and the control channels include a PUCCH (Physical Uplink Control Channel). For example, terminal 200 receives control information from base station 100 using the PUCCH and transmits uplink data signals using the PUSCH.

[0089] The reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, the reference signals such as DMRS and PTRS are used for demodulating the uplink data signal and are transmitted using an uplink channel (for example, PUSCH).

[0090] The control unit 203 controls the communication operations of the terminal 200 , including the reception processing in the reception unit 201 and the transmission processing in the transmission unit 202 .

[0091] For example, the control unit 203 acquires information such as data and control information from a higher layer and outputs it to the transmitting unit 202. Also, the control unit 203 outputs, for example, data and control information received from the receiving unit 201 to the higher layer.

[0092] For example, the control unit 203 controls transmission of information to be fed back to the base station 100. The information to be fed back to the base station 100 may include, for example, HARQ-ACK, Channel State Information (CSI), or a Scheduling Request (SR). The information to be fed back to the base station 100 may be included in UCI. The UCI is transmitted in the resources of the PUCCH.

[0093] Control unit 203 configures PUCCH resources based on configuration information (for example, configuration information such as a PUCCH cell timing pattern and / or DCI notified by RRC) received from base station 100. Control unit 203 determines PUCCH resources to be used for transmitting information to be fed back to base station 100. Under the control of control unit 203, transmission unit 202 transmits the information to be fed back to base station 100 in the PUCCH resources determined by control unit 203.

[0094] Note that the channel used for transmitting the DL signal and the channel used for transmitting the UL signal are not limited to the above-mentioned examples. For example, the channel used for transmitting the DL signal and the channel used for transmitting the UL signal may include a Random Access Channel (RACH) and a Physical Broadcast Channel (PBCH). The RACH may be used to transmit Downlink Control Information (DCI) including a Random Access Radio Network Temporary Identifier (RA-RNTI), for example.

[0095] Here, the control unit 203 may multiplex channels with different priorities, for example, the control unit 203 may multiplex an LP channel and an HP channel.

[0096] Transmitter 202 may transmit multiplexed channels regardless of an instruction to cancel uplink transmission. In other words, transmitter 202 does not need to cancel multiplexed channels regardless of an instruction to cancel uplink transmission. For example, transmitter 202 does not need to cancel PUSCHs including the LP channel and HP channel regardless of the UL CI in DCI format 2_4. This operation allows terminal 200 to appropriately cancel uplink transmission of channels with different priorities multiplexed within the terminal. Furthermore, terminal 200 can transmit multiplexed channels including the HP channel.

[0097] Furthermore, transmitting section 202 may cancel transmission of a channel with one priority level based on an instruction to cancel uplink transmission. For example, transmitting section 202 may cancel a PUSCH including only an LP channel based on an UL CI in DCI format 2_4. Transmitting section 202 may cancel a PUSCH including only an HP channel based on an UL CI in DCI format 2_4. This operation enables terminal 200 to appropriately cancel transmission of a channel with one priority level.

[0098] Furthermore, transmitting section 202 may cancel transmission of multiplexed channels based on an instruction to cancel uplink transmission. For example, transmitting section 202 may cancel PUSCH including the LP channel and the HP channel based on UL CI in DCI format 2_4. This operation allows terminal 200 to appropriately cancel uplink transmission of channels with different priorities multiplexed within the terminal. Furthermore, terminal 200 can cancel transmission of multiplexed channels including the LP channel.

[0099] Furthermore, transmitter 202 may apply an instruction to cancel uplink transmission to multiplexed channels based on signaling parameters. For example, transmitter 202 may apply UL CI in DCI format 2_4 to multiplexed channels based on RRC parameters. This operation enables terminal 200 to appropriately cancel uplink transmission of channels with different priorities multiplexed within the terminal.

[0149] <Reference signal> The reference signal may be abbreviated as RS (Reference Signal) or may be called a pilot depending on the applicable standard.

[0150] <The meaning of "based on"> 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."

[0151] <"First", "Second"> 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.

[0152] <Means> In the configuration of each of the above devices, the "means" may be replaced with "section", "circuit", "device", etc.

[0153] <Open format> In the present disclosure, when terms such as "include", "including" and their variants are used, these terms are intended to be inclusive, similar to the term "comprising". Further, the term "or" used in the present disclosure is intended not to be an exclusive disjunction.

[0157] 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.

[0158] 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.

[0159] 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, etc. instead of a subframe.

[0160] 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 radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. However, the definition of TTI is not limited to this.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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 equal to or greater than 1 ms.

[0165] A resource block (RB) is a resource allocation unit in the time domain and 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 numerology, for example, 12. The number of subcarriers included in an RB may also be determined based on numerology.

[0166] 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.

[0167] 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, or the like.

[0168] 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.

[0169] 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 given BWP and numbered within that BWP.

[0170] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0171] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0172] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, 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. may be changed in various ways.

[0173] <Maximum transmission power> The "maximum transmit power" in this disclosure may mean the maximum value of transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0174] <Article> 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.

[0175] <"Different"> 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." [Industrial Applicability]
