In the multiplexing process, the terminal cancels the uplink transmission using radio resources that overlap with the radio resources for the transmission of the multiplexed result.

Description

Technical Field

[0001] The present disclosure relates to a terminal and a wireless communication method corresponding to multiplexing of uplink traffic.

Background Art

[0002] The 3rd Generation Partnership Project (3GPP) is standardizing the 5th generation mobile communication system (also called 5G, New Radio (NR) or Next Generation (NG)), and is also proceeding with the standardization of the next generation called Beyond 5G, 5G Evolution or 6G.

[0003] In Release 16 of 3GPP, format 2_4 of downlink control information (DCI) was introduced, and it is possible to cancel UL transmissions with low priority in order to ensure (preempt) UL transmissions with high priority.

[0004] Also, in Release 17 of 3GPP, multiplexing within a terminal (User Equipment, UE) of UL traffic having different priorities has been agreed (for example, Non-Patent Document 1).

Summary of the Invention

[0006] However, regarding the multiplexing of UL traffic having different priorities described above, the following problems are considered to exist.

[0007] Specifically, even if the multiplexing of UL traffic having different priorities is enabled and the conditions for multiplexing are satisfied, when the UL channel (for example, PUCCH (Physical Uplink Control Channel), uplink control channel) overlaps with the radio resources indicated by a UL transmission cancellation indication (UL CI), a dynamic slot format indication (SFI), a semi-static downlink (DL) symbol, or a synchronization signal block (SSB (SS / PBCH Block)), the UE cannot determine how to execute the multiplexing process.

[0008] Therefore, the following disclosure has been made in view of such a situation, and an object is to provide a terminal and a wireless communication method capable of more reliably realizing the multiplexing of UL traffic having different priorities even when overlapping with radio resources by other indications such as UL CI.

[0009] One aspect of the present disclosure is a terminal (UE200) including a control unit (control unit 270) that executes a multiplexing process for first traffic having a first priority and second traffic having a second priority different from the first priority, and a transmission unit (wireless signal transceiver unit 210) that transmits a multiplexing result obtained by multiplexing the first traffic and the second traffic, wherein the control unit cancels an uplink transmission using radio resources overlapping with the transmission of the multiplexing result in the multiplexing process.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments will be described with reference to the drawings. Note that the same or similar reference numerals are assigned to the same functions and configurations, and the description thereof will be omitted as appropriate.

[0012] (1) Overall schematic configuration of the wireless communication system FIG. 1 is an overall schematic configuration diagram of a wireless communication system 10 according to this embodiment. The wireless communication system 10 is a wireless communication system compliant with 5G New Radio (NR), and includes a Next Generation-Radio Access Network 20 (hereinafter, NG-RAN 20) and a user terminal 200 (User Equipment 200, hereinafter, UE 200).

[0013] NG-RAN 20 includes a radio base station 100 (hereinafter, gNB 100). Note that the specific configuration of the wireless communication system 10 including the number of gNBs and UEs is not limited to the example shown in FIG. 1.

[0014] Actually, NG-RAN 20 includes a plurality of NG-RAN Nodes, specifically, gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). Note that NG-RAN 20 and 5GC may be simply expressed as "network".

[0015] gNB 100 is a radio base station compliant with NR and performs wireless communication with UE 200 according to NR. gNB 100 and UE 200 can support Massive MIMO that generates a more directive beam by controlling wireless signals transmitted from a plurality of antenna elements, Carrier Aggregation (CA) that bundles and uses a plurality of Component Carriers (CCs), and Dual Connectivity (DC) that enables simultaneous communication between the UE and each of a plurality of NG-RAN Nodes.

[0016] The wireless communication system 10 supports FR1 and FR2. The frequency bands of each FR are as follows.

[0017] · FR1: 410 MHz to 7.125 GHz · FR2: 24.25 GHz to 52.6 GHz In FR1, a Sub-Carrier Spacing (SCS) of 15, 30, or 60 kHz is used, and a bandwidth (BW) of 5 - 100 MHz may be used. FR2 is at a higher frequency than FR1, an SCS of 60 or 120 kHz (240 kHz may be included) is used, and a bandwidth (BW) of 50 - 400 MHz may be used.

[0018] Furthermore, the wireless communication system 10 may also support frequency bands higher than the frequency band of FR2. Specifically, the wireless communication system 10 may support frequency bands exceeding 52.6 GHz and up to 114.25 GHz.

[0019] Also, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform - Spread (DFT-S-OFDM) with a larger Sub-Carrier Spacing (SCS) may be applied. Furthermore, DFT-S-OFDM may be applied not only to the uplink (UL) but also to the downlink (DL).

[0020] FIG. 2 shows a configuration example of a radio frame, sub-frame, and slot used in the wireless communication system 10.

[0021] As shown in FIG. 2, one slot is composed of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). Note that the number of symbols constituting one slot does not necessarily have to be 14 symbols (for example, 28, 56 symbols). Also, the number of slots per sub-frame may vary depending on the SCS. Furthermore, the SCS may be wider than 240 kHz (for example, as shown in FIG. 3, 480 kHz, 960 kHz) Note that the time direction (t) shown in FIG. 2 may also be referred to as a time domain, a symbol period, a symbol time, etc. Also, the frequency direction may also be referred to as a frequency domain, a resource block, a subcarrier, a BWP (Bandwidth part), etc.

[0022] Also, 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 a channel coding rate, etc., which are necessary for each user (UE) to demodulate data.

[0023] In particular, in this embodiment, DCI format 2_4 may be used to ensure (preempt) high-priority uplink (UL) transmission and cancel low-priority UL transmission. DCI format 2_4 may be used to notify a group of UEs of physical resource blocks (PRBs) and OFDM symbols that cancel corresponding UL transmissions from UE200. That is, DCI format 2_4 may be interpreted as a format that notifies PRBs and OFDM symbols for which UL transmission has been canceled. Note that "cancel" may also be interpreted as "cancel", "stop", or "abort", etc.

[0024] DCI format 2_4 may be represented in the following format.

[0025] ·Cancellation indication 1, Cancellation indication 2, …, Cancellation indication N UE 200 can cancel UL transmissions, specifically PUSCH (Physical Uplink Shared Channel, uplink data channel) or transmissions such as Sounding Reference Signal (SRS), based on the UL Cancellation Indication (which may also be referred to as UL CI) indicated by DCI format 2_4. Note that the PUCCH (Physical Uplink Control Channel, uplink control channel) may also be cancelled by the UL CI.

[0026] Also, in the radio communication system 10, Intra-UE multiplexing of UL traffic with different priorities may be supported in UE 200. Specifically, UE 200 can multiplex low-priority (LP) traffic and high-priority (HP) traffic, and transmit the result of the multiplexed traffic (multiplexing result) via the UL.

[0027] Traffic may be read as a channel, data channel, control channel, path, data or control data, etc. Also, LP may be expressed as the first priority and HP as the second priority (or vice versa). The multiplexing result may be read as an outcome, result, consequence or output, etc. Note that specific operation examples of Intra-UE multiplexing will be described later.

[0028] (2) Functional block configuration of the radio communication system Next, the functional block configuration of the radio communication system 10 will be described. Specifically, the functional block configuration of UE 200 will be described.

[0029] FIG. 3 is a functional block configuration diagram of UE 200. As shown in FIG. 3, UE 200 includes a radio signal transceiver unit 210, an amplifier unit 220, a modulation / demodulation unit 230, a control signal / reference signal processing unit 240, an encoding / decoding unit 250, a data transceiver unit 260, and a control unit 270. Note that gNB 100 (radio base station) may also have a similar functional block configuration.

[0030] The radio signal transceiver unit 210 transmits and receives radio signals according to NR. The radio signal transceiver unit 210 supports Massive MIMO, CA that bundles multiple CCs for use, and DC that enables simultaneous communication between the UE and two NG-RAN Nodes respectively.

[0031] In particular, in this embodiment, the radio signal transceiver unit 210 can transmit UL traffic with different priorities via a predetermined UL channel. Specifically, the radio signal transceiver unit 210 can transmit a multiplexing result in which low-priority (LP) traffic (first traffic) and high-priority (HP) traffic (second traffic) are multiplexed. In this embodiment, the radio signal transceiver unit 210 constitutes a transmission unit.

[0032] The amplifier unit 220 is composed of a PA (Power Amplifier) / LNA (Low Noise Amplifier), etc. The amplifier unit 220 amplifies the signal output from the modulation / demodulation unit 230 to a predetermined power level. Also, the amplifier unit 220 amplifies the RF signal output from the radio signal transceiver unit 210.

[0033] The modulation / demodulation unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication destination (such as gNB 100). In the modulation / demodulation unit 230, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform - Spread (DFT-S-OFDM) may be applied. Also, DFT-S-OFDM may be used not only for the uplink (UL) but also for the downlink (DL).

[0034] The control signal / reference signal processing unit 240 performs processing related to various control signals transmitted and received by the UE 200, and processing related to various reference signals transmitted and received by the UE 200.

[0035] Specifically, the control signal / reference signal processing unit 240 receives various control signals transmitted from the gNB 100 via a predetermined control channel, for example, control signals of the radio resource control layer (RRC). Also, the control signal / reference signal processing unit 240 transmits various control signals to the gNB 100 via a predetermined control channel.

[0036] The control signal / reference signal processing unit 240 performs processing using reference signals (RS) such as Demodulation Reference Signal (DMRS) and Phase Tracking Reference Signal (PTRS).

[0037] DMRS is a reference signal (pilot signal) known between the base station and the terminal specific to each terminal for estimating the fading channel used for data demodulation. PTRS is a reference signal specific to each terminal for the purpose of estimating phase noise, which is a problem in high frequency bands.

[0038] Note that, in addition to DMRS and PTRS, the reference signal may include Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and Positioning Reference Signal (PRS) for position information, etc.

[0039] Also, the channels include a control channel and a data channel. The control channel may include Physical Downlink Control Channel (PDCCH), Physical Uplink Control Channel (PUCCH), Random Access Channel (RACH, including Downlink Control Information (DCI) with Random Access Radio Network Temporary Identifier (RA-RNTI)), and Physical Broadcast Channel (PBCH), etc.

[0040] Also, the data channel includes Physical Downlink Shared Channel (PDSCH), and Physical Uplink Shared Channel (PUSCH), etc. Data may mean the data transmitted via the data channel.

[0041] PUCCH may be interpreted as a UL physical channel used for transmitting Uplink Control Information (UCI). UCI can be transmitted either by PUCCH or PUSCH depending on the situation. Note that DCI may always be transmitted by PDCCH and may not be transmitted via PDSCH.

[0042] The UCI may include at least any one of ACK / NACK of Hybrid Automatic Repeat Request (HARQ), a scheduling request (SR) from the UE200, and Channel State Information (CSI).

[0043] Also, the timing and radio resources for transmitting the PUCCH may be controlled by DCI in the same manner as the data channel.

[0044] The encoding / decoding unit 250 performs data segmentation / concatenation, channel coding / decoding, etc. for each predetermined communication destination (gNB100 or another gNB).

[0045] Specifically, the encoding / decoding unit 250 divides the data output from the data transmission / reception unit 260 into a predetermined size and performs channel coding on the divided data. Also, the encoding / decoding unit 250 decodes the data output from the modulation / demodulation unit 230 and concatenates the decoded data.

[0046] The data transmission / reception unit 260 performs transmission and reception of Protocol Data Unit (PDU) and Service Data Unit (SDU). Specifically, the data transmission / reception unit 260 performs assembly / disassembly of PDU / SDU in a plurality of layers (such as the Medium Access Control layer (MAC), the Radio Link Control layer (RLC), and the Packet Data Convergence Protocol layer (PDCP)). Also, the data transmission / reception unit 260 performs error correction and retransmission control of data based on Hybrid Automatic Repeat Request (HARQ).

[0047] The control unit 270 controls each functional block constituting the UE200. In particular, in this embodiment, the control unit 270 can perform multiplexing processing of UL traffic having different priorities.

[0048] Specifically, the control unit 270 can perform multiplexing processing on traffic (first traffic) with a low priority (first priority) and traffic (second traffic) with a high priority that is higher than the low priority (which may be expressed as a second priority different from the first priority). Note that multiplexing may be read as terms such as multiplexing, combining, or superimposing. Also, as described above, traffic may be read as a channel, data channel, control channel, path, data, or control data, etc.

[0049] The control unit 270 multiplexes a plurality of low-priority (LP) traffic (first traffic) and multiplexes a plurality of high-priority (HP) traffic (second traffic), and may further multiplex a multiplexing result (first multiplexing result) in which a plurality of LP traffic is multiplexed and a multiplexing result (second multiplexing result) in which a plurality of HP traffic is multiplexed.

[0050] Also, the control unit 270 may generate a multiplexing result by multiplexing one or more LP traffic and one or more HP traffic.

[0051] Alternatively, the control unit 270 may generate a multiplexing result by multiplexing a plurality of LP traffic, and generate a multiplexing result by multiplexing the multiplexing result and one or more HP traffic. Conversely, the control unit 270 may generate a multiplexing result by multiplexing a plurality of HP traffic, and generate a multiplexing result by multiplexing the multiplexing result and one or more LP traffic.

[0052] Note that the multiplexing method of LP traffic and HP traffic is not limited to these methods. For example, the control unit 270 may execute a plurality of processes of multiplexing one or more LP traffic and one or more HP traffic, and execute a hierarchical multiplexing process of further multiplexing the plurality of multiplexing results. Also, the hierarchy of the multiplexing process may be more.

[0053] Further, in the multiplexing process, the control unit 270 may cancel the uplink transmission that uses radio resources overlapping with the transmission of the multiplexing result. Specifically, the control unit 270 can execute control regarding cancellation of uplink transmission (UL transmission) based on UL CI.

[0054] More specifically, the control unit 270 may cancel the PUSCH that overlaps with the transmission of the multiplexing result. Further, the uplink transmission may include reference signals such as SRS. Furthermore, the PUCCH may also be a target for cancellation.

[0055] The control unit 270 may cancel the UL transmission at any layer of the multiplexing process described above. For example, the control unit 270 may cancel the UL transmission before multiplexing a plurality of LP traffics and / or a plurality of HP traffics.

[0056] Further, after multiplexing the LP traffic and / or the HP traffic, and before multiplexing the multiplexing result (first multiplexing result) of a plurality of LP traffics and the multiplexing result (second multiplexing result) of a plurality of HP traffics, the control unit 270 may cancel the UL transmission.

[0057] Alternatively, the control unit 270 may cancel the UL transmission after multiplexing the multiplexing result (first multiplexing result) of a plurality of LP traffics and the multiplexing result (second multiplexing result) of a plurality of HP traffics.

[0058] Further, the control unit 270 may cancel the UL transmission after multiplexing one or more LP traffics and one or more HP traffics.

[0059] (3) Operation of the wireless communication system Next, the operation of the wireless communication system 10 will be described. Specifically, the operation regarding the Intra-UE multiplexing of UL traffic with different priorities within the UE200, and the cancellation of UL transmission by the UL Cancellation Indication (UL CI) indicated by the DCI format 2_4 will be described.

[0060] (3.1) Premises Regarding Intra-UE multiplexing, the following processing order may be defined.

[0061] · The processing order of Intra-UE multiplexing for traffic (channels) with the same priority, and the priorities of traffic (channels) with different priorities may be as follows.

[0062] · Multiplexing of LP channels In this case, if there is an overlap of radio resources between the LP channel and the HP channel, the LP channel may be cancelled.

[0063] · Multiplexing of HP channels In this case, if there is an overlap of radio resources between the LP channel and the HP channel, the LP channel may be cancelled. Note that the radio resources may include time resources and frequency resources. Also, the LP channel and the HP channel may be interpreted as synonymous with the LP traffic and the HP traffic as described above, but hereinafter, the terms LP channel and HP channel will mainly be used.

[0064] · The relationship between the processing order of Intra-UE multiplexing and the UL CI or the Dynamic Slot Format Indication (SFI) may be as follows.

[0065] · Intra-UE multiplexing is executed first ·Cancellation of UL transmission by UL CI or Dynamic SFI Note that the processing order of Intra-UE multiplexing and its relationship with semi-static downlink (DL) symbols or synchronization signal blocks (SSB (SS / PBCH Block)) may be the same as or different from that of UL CI, etc. A semi-static downlink (DL) symbol may be interpreted as a symbol whose usage (e.g., UL / DL separation, always available or not) can be changed by configuration.

[0066] Figure 4 shows an example of the UL CI Scheme. As described above, in the wireless communication system 10, DCI format 2_4 may be used to ensure high-priority UL transmissions and cancel low-priority UL transmissions.

[0067] As shown in Figure 4, when the UL CI for UE #1 for eMBB (enhanced Mobile Broadband) is notified by DCI format 2_4, UE #1 cancels the UL transmission. Thereby, the UL transmission of UE #2 for URLLC (Ultra-Reliable and Low Latency Communications), that is, the high-priority UL transmission, is ensured.

[0068] Regarding Intra-UE multiplexing, if multiplexing of traffic (channels) with different priorities is not enabled in UE200, UE200 may follow the conventional processing order (i.e., the processing order without multiplexing). Also, UE200 may follow the conventional processing order even when the multiplexing is enabled but the multiplexing conditions are not met.

[0069] On the other hand, when the multiplexing is enabled, the multiplexing conditions are met, and the UL channel overlaps with the radio resources indicated by UL CI, Dynamic SFI, semi-static DL symbols, or SSB in UE200, UE200 may operate according to any of the following operation examples.

[0070] (3.2) Operation Example The following describes the general operation and some operation examples regarding the Intra-UE multiplexing of UE200, the transmission of multiplexing results, and the cancellation of UL transmission when the radio resources indicated by UL CI, etc., overlap.

[0071] (3.2.1) General Operation The multiplexing process (order of multiplexing) between the LP channel and the HP channel may be any of the following.

[0072] ·Possibility 1: Execute the multiplexing process between channels with the same priority, and then execute the multiplexing process between the multiplexing outcome of the LP channel and the multiplexing outcome of the HP channel.

[0073] ·Possibility 2: Mix all the LP channels and HP channels and execute the multiplexing process (similar to the current procedure for multiplexing multiple UL PUCCHs with the same priority).

[0074] ·Possibility 3: Execute the multiplexing process between LP channels, and then execute the multiplexing process between the multiplexing outcome of the LP channel and the HP channel.

[0075] ·Possibility 4: Execute the multiplexing process between HP channels, and then execute the multiplexing process between the multiplexing outcome of the HP channel and the LP channel.

[0076] Figure 5 shows a sequence example regarding Intra-UE multiplexing and UL transmission cancellation between UE200 and the network (NG-RAN20).

[0077] As shown in Fig. 5, the UE 200 can transmit UE capability (which may also be referred to as UE Capability Information) indicating the capabilities of the UE 200 to the network (NG-RAN 20). Note that the UE 200 may transmit the UE Capability Information in response to receiving an enquiry about the capabilities of the UE 200 (UE Capability Enquiry) from the network.

[0078] The UE capability may include the capabilities related to the Intra-UE multiplexing described above. The capabilities related to Intra-UE multiplexing may indicate which of the multiplexing processes (order of multiplexing) of Possibility 1 to 4 described above it corresponds to.

[0079] Based on the received UE Capability Information, the network may transmit a message of a higher layer (e.g., RRC) or DCI to the UE 200. The RRC message may include uplinkCancellationPriority indicating the priority regarding the cancellation of UL transmission.

[0080] The uplinkCancellationPriority is defined in 3GPP TS38.331. Note that the DCI (e.g., DCI format 2_4) may include a display similar to the uplinkCancellationPriority.

[0081] The uplinkCancellationPriority can configure the cancellation operation of UL transmissions when both the UL CI and the in-UE priority indicator are set for a specific UE. If the uplinkCancellationPriority field exists, the UL CI may only apply to UL transmissions indicated or set as low priority. On the other hand, if the uplinkCancellationPriority field does not exist, the UL CI may apply to UL transmissions regardless of the priority.

[0082] (3.2.2) Operation Example 1 In this operation example, the UE 200 applies Possibility 1 regarding the Intra-UE multiplexing described above. FIG. 6 shows an example of Intra-UE multiplexing and UL transmission cancellation according to Operation Example 1. As shown in FIG. 6, the UE 200 may multiplex a plurality of channels having the same priority.

[0083] Specifically, the UE 200 multiplexes a plurality of LP channels to generate a multiplexing result (LP outcome). Also, the UE 200 multiplexes a plurality of HP channels to generate a multiplexing result (HP outcome). Furthermore, the UE 200 multiplexes the LP outcome and the HP outcome to generate a multiplexing result (HP+LP).

[0084] Note that the contents of the LP channels and the HP channels may include HARQ-ACK, scheduling requests (SR), Channel State Information (CSI), etc. (the same applies hereinafter). Note that the contents of the LP channels and the HP channels are not limited to these, and other contents may be included.

[0085] In the case of this operation example, the UE 200 may cancel UL transmissions when overlapping with radio resources indicated by the UL CI, etc., according to any of the following options.

[0086] ·(Option 1): Before multiplexing the LP channel and the HP channel, the UE 200 cancels the dedicated channel (dedicated channel, LP channel and / or HP channel) that overlaps with the radio resources indicated by the UL CI.

[0087] ·(Option 2): After multiplexing the LP channel and the HP channel but before multiplexing the LP outcome and the HP outcome, the UE 200 cancels the dedicated channel that overlaps with the radio resources indicated by the UL CI.

[0088] ·(Option 3): After multiplexing the LP outcome and the HP outcome, the UE 200 cancels the dedicated channel that overlaps with the radio resources indicated by the UL CI.

[0089] Note that the dedicated channel (the channel to be cancelled including only the LP channel or the HP channel, or both the LP channel and the HP channel) may be set by parameters of the upper layer (such as RRC), or may be predefined in the 3GPP specifications. Alternatively, the dedicated channel may be specified by DCI. Also, for the specification of the dedicated channel, uplinkCancellationPriority may be used in the case of RRC, or new parameters may be provided.

[0090] Also, the above Options 1 to 3 regarding the cancellation of the dedicated channel may be applied in combination according to the cancellation target and / or the 3GPP specifications.

[0091] (3.2.3) Operation Example 2 In this operation example, UE200 applies Possibility 2 regarding Intra-UE multiplexing described above. FIG. 7 shows an example of Intra-UE multiplexing and UL transmission cancellation according to Operation Example 2. As shown in FIG. 7, UE200 may generate a multiplexing result (HP+LP) by multiplexing one or more LP channels and one or more HP channels.

[0092] In the case of this operation example, UE200 may cancel UL transmission when it overlaps with radio resources indicated by UL CI or the like according to any of the following options.

[0093] ·(Option 1): Before multiplexing the LP channel and the HP channel, UE200 cancels a dedicated channel (dedicated channel, LP channel and / or HP channel) that overlaps with the radio resources indicated by the UL CI.

[0094] ·(Option 2): After multiplexing the LP channel and the HP channel, UE200 cancels a dedicated channel that overlaps with the radio resources indicated by the UL CI.

[0095] Note that, similar to Operation Example 1, the dedicated channel (a channel to be cancelled including only the LP channel or the HP channel, or both the LP channel and the HP channel) may be set by parameters of a higher layer (such as RRC), or may be predefined in the 3GPP specifications. Alternatively, the dedicated channel may be specified by DCI. Also, for the specification of the dedicated channel, uplinkCancellationPriority may be used in the case of RRC, or a new parameter may be provided.

[0096] Also, the above-described Options 1 and 2 regarding the cancellation of the dedicated channel may be applied in combination according to the cancellation target and / or the 3GPP specifications.

[0097] (3.2.4) Operation Example 3 In this operation example, UE 200 applies Possibility 3 regarding Intra-UE multiplexing described above. FIG. 8 shows an example of Intra-UE multiplexing and UL transmission cancellation according to Operation Example 3. As shown in FIG. 8, UE 200 may generate a multiplexing result (LP outcome) by multiplexing a plurality of LP channels, and generate a multiplexing result (HP+LP) by multiplexing the multiplexing result and one or more HP channels.

[0098] In the case of this operation example, UE 200 may cancel UL transmission when it overlaps with the radio resources indicated by the UL CI or the like according to any of the following options.

[0099] · (Option 1): UE 200 cancels the LP channels that overlap with the radio resources indicated by the UL CI before multiplexing a plurality of LP channels.

[0100] · (Option 2): UE 200 cancels the dedicated channels (dedicated channel, LP channel and / or HP channel) that overlap with the radio resources indicated by the UL CI before multiplexing the multiplexing result (LP outcome) of the LP channels and a plurality of HP channels.

[0101] · (Option 3): UE 200 cancels the dedicated channels that overlap with the radio resources indicated by the UL CI after multiplexing the LP outcome and a plurality of HP channels.

[0102] Note that, similar to Operation Example 1, the dedicated channel (the channel to be cancelled including only the LP channel or the HP channel, or both the LP channel and the HP channel) may be set by parameters of the upper layer (such as RRC), or may be predefined in the 3GPP specifications. Alternatively, the dedicated channel may be specified by DCI. Also, for the specification of the dedicated channel, in the case of RRC, uplinkCancellationPriority may be used, or a new parameter may be provided.

[0103] Also, the above-described Options 1 to 3 regarding the cancellation of the dedicated channel may be applied in combination according to the cancellation target and / or the 3GPP specifications.

[0104] (3.2.5) Operation Example 4 In this operation example, UE200 applies Possibility 4 regarding the above-described Intra-UE multiplexing. FIG. 9 shows an example of Intra-UE multiplexing and UL transmission cancellation according to Operation Example 4. As shown in FIG. 9, UE200 may generate a multiplexing result (HP outcome) by multiplexing a plurality of HP channels, and generate a multiplexing result (HP+LP) by multiplexing the multiplexing result and one or more LP channels.

[0105] In the case of this operation example, UE200 may cancel UL transmission when it overlaps with the radio resources indicated by the UL CI or the like according to any of the following options.

[0106] ·(Option 1): UE200 cancels the HP channel that overlaps with the radio resources indicated by the UL CI before multiplexing a plurality of HP channels.

[0107] ·(Option 2): Before multiplexing the multiple results (HP outcome) of the HP channel and the multiple LP channels, the UE 200 cancels the dedicated channel (dedicated channel, LP channel, and / or HP channel) that overlaps with the radio resources indicated by the UL CI.

[0108] ·(Option 3): After multiplexing the HP outcome and the multiple LP channels, the UE 200 cancels the dedicated channel that overlaps with the radio resources indicated by the UL CI.

[0109] Similar to Operation Example 1, the dedicated channel (the channel to be cancelled including only the LP channel or HP channel, or both the LP channel and HP channel) may be set by parameters of the upper layer (such as RRC) or may be predefined in the 3GPP specifications. Alternatively, the dedicated channel may be specified by DCI. Also, for the specification of the dedicated channel, in the case of RRC, uplinkCancellationPriority may be used or a new parameter may be provided.

[0110] Also, the above-described Options 1 to 3 regarding the cancellation of the dedicated channel may be applied in combination according to the cancellation target and / or the 3GPP specifications.

[0111] (3.2.6) Change Example Regarding the above-described operation examples, the following changes may be made. For example, the cancellation of UL transmission (dedicated channel) by the UL CI may be replaced by cancellation by Dynamic SFI, quasi-static DL symbols, or SSB. Furthermore, cancellations by the UL CI, Dynamic SFI, quasi-static DL symbols, or SSB may be combined.

[0112] As described above, the UL transmissions (dedicated channels) to be cancelled may include only the LP channel or the HP channel, or both the LP channel and the HP channel, and the UL channels to be cancelled may include PUCCH and / or PUSCH.

[0113] Also, similar to 3GPP Release 16, the UL CI may target only PUSCH or SRS (in this case, there is no impact on the relevant 3GPP specifications). Note that the priority of the cancelled PUSCH may be set by parameters of the upper layer (such as RRC, e.g., uplinkCancellationPriority described above).

[0114] Alternatively, in addition to PUSCH and SRS, the UL CI may be able to cancel PUCCH. Thereby, better spectral efficiency can be achieved. Also in this case, the priorities of the cancelled PUSCH and the cancelled PUSCH may be set by parameters of the upper layer (uplinkCancellationPriority). Further, also in this case, the UL CI may be replaced by cancellation using Dynamic SFI, quasi-static DL symbols, or SSB.

[0115] (4) Operations and Effects According to the above-described embodiments, the following operations and effects can be obtained. Specifically, the UE 200 can perform multiplexing processing of the LP channel and the HP channel with a higher priority than the low priority, and in the multiplexing processing, cancel UL transmissions using radio resources that overlap with the transmission of the multiplexing results (LP outcome, HP outcome, etc.).

[0116] Therefore, even when the transmission of multiple results overlaps with radio resources indicated by UL CI or the like, the UE 200 can achieve efficient multiplexing processing. That is, according to the UE 200, even when radio resources overlap due to other indications such as UL CI, multiplexing of UL traffic (channels) with different priorities can be more reliably achieved.

[0117] In this embodiment, the UE 200 can execute various multiplexing processes of Possibility 1 to 4 described above. Therefore, appropriate multiplexing processing can be realized according to the content, requirement conditions, etc. of the LP channel and / or HP channel.

[0118] In this embodiment, the UE 200 can cancel UL transmission before multiplexing a plurality of LP channels and / or a plurality of HP channels, after multiplexing the LP channel and / or HP channel, before multiplexing the multiplexing result of the multiplexed plurality of LP channels and the multiplexing result of the multiplexed plurality of HP channels, after multiplexing the multiplexing result of the multiplexed plurality of LP channels and the multiplexing result of the multiplexed plurality of HP channels, or after multiplexing one or more LP channels and one or more HP channels.

[0119] Therefore, the UE 200 can execute cancellation of UL transmission in an appropriate multiplexing layer in consideration of the load of the multiplexing process, the influence of the UE 200 due to cancellation of UL transmission, etc., and can contribute to efficient operation such as power consumption savings.

[0120] (5) Other Embodiments As described above, the embodiments have been described, but it is obvious to those skilled in the art that the present invention is not limited to the description of the embodiments, and various modifications and improvements are possible.

[0121] For example, in the above-described embodiment, a radio communication system according to 5G (NR) is assumed, but the radio communication system 10 may be a radio communication system according to a system called Beyond 5G, 5G Evolution, or 6G.

[0122] In addition, the block diagram (FIG. 3) used in the description of the above-described embodiments shows blocks of functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Also, the method for realizing each functional block is not particularly limited.

[0125] In the following description, the term "device" can be read as a circuit, device, unit, etc. The hardware configuration of the device may be configured to include one or more of each device shown in the figure, or may be configured without including some of the devices.

[0126] Each functional block of the device (see Figure 3) is realized by any hardware element of the computer device or a combination of the hardware elements.

[0127] Also, each function in the device is realized by loading a predetermined software (program) onto hardware such as the processor 1001 and the memory 1002, causing the processor 1001 to perform calculations, control communication by the communication device 1004, or control at least one of reading and writing data in the memory 1002 and the storage 1003.

[0129] Also, the processor 1001 reads a program (program code), software module, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and executes various processes according to these. As the program, a program for causing the computer to execute at least a part of the operations described in the above embodiments is used.

The above-described recording medium may be, for example, a database, a server, or other appropriate media including at least one of the memory 1002 and the storage 1003.

[0132] The communication device 1004 is hardware (a transmission / reception device) for performing communication between computers via at least one of a wired network and a wireless network, and is also referred to as, for example, a network device, a network controller, a network card, a communication module, etc.

[0133] The communication device 1004 may be configured to include, for example, a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. in order to implement at least one of Frequency Division Duplex (FDD) and Time Division Duplex (TDD).

[0134] The input device 1005 is an input device that receives external input (for example, a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.). The output device 1006 is an output device that performs output to the outside (for example, a display, a speaker, an LED lamp, etc.). Note that the input device 1005 and the output device 1006 may have an integrated configuration (for example, a touch panel).

[0135] Also, each device such as the processor 1001 and the memory 1002 is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus or may be configured using different buses for each device.

[0136] Furthermore, the device may be configured to include hardware such as a microprocessor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), etc., and some or all of each functional block may be realized by the hardware. For example, the processor 1001 may be implemented using at least one of these hardware.

[0137] Also, the notification of information is not limited to the aspects / embodiments described in the present disclosure, and other methods may be used. For example, the notification of information may be implemented by physical layer signaling (e.g., Downlink Control Information (DCI), Uplink Control Information (UCI)), upper layer signaling (e.g., RRC signaling, Medium Access Control (MAC) signaling, notification information (Master Information Block (MIB), System Information Block (SIB))), other signals, or combinations thereof. Also, RRC signaling may be referred to as an RRC message, and may be, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

[0138] Each aspect / embodiment described in the present disclosure may be applied to at least one of systems using Long Term Evolution (LTE), LTE-Advanced (LTE-A), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), Future Radio Access (FRA), New Radio (NR), W-CDMA (registered trademark), GSM (registered trademark), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), other suitable systems, and next-generation systems extended based thereon.

[0139] The processing procedures, sequences, flowcharts, etc. of each aspect / embodiment described in this disclosure may be reordered as long as there is no contradiction. For example, for the methods described in this disclosure, the elements of various steps are presented using an exemplary order and are not limited to the specific order presented.

[0140] Specific operations assumed to be performed by a base station in this disclosure may, in some cases, be performed by its upper node. In a network consisting of one or more network nodes having a base station, various operations performed for communication with a terminal can clearly be performed by at least one of the base station and other network nodes other than the base station (for example, but not limited to, MME or S-GW, etc.). Although the case where there is one other network node other than the base station is exemplified above, a combination of a plurality of other network nodes (for example, MME and S-GW) may also be possible.

[0141] Information, signals (such as information) can be output from an upper layer (or lower layer) to a lower layer (or upper layer). They may also be input and output via a plurality of network nodes.

[0142] The input and output information may be stored in a specific location (for example, memory) or may be managed using a management table. The input and output information can be overwritten, updated, or appended. The output information may be deleted. The input information may be transmitted to other devices.

[0143] The determination may be made by a value represented by 1 bit (0 or 1), by a Boolean value (true or false), or by a numerical comparison (for example, comparison with a predetermined value).

[0144] Each aspect / embodiment described in this disclosure may be used alone, in combination, or switched and used during execution. Also, the notification of predetermined information (for example, the notification of "being X") is not limited to being explicitly performed, and may be performed implicitly (for example, by not performing the notification of the predetermined information).

[0145] Software should be broadly interpreted to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc., whether called software, firmware, middleware, microcode, a hardware description language, or by any other name.

[0146] Also, software, instructions, information, etc. may be transmitted and received via a transmission medium. For example, when software is transmitted from a website, server, or other remote source using at least one of wired technologies (such as coaxial cables, optical fiber cables, twisted pairs, Digital Subscriber Line (DSL), etc.) and wireless technologies (such as infrared rays, microwaves, etc.), at least one of these wired and wireless technologies is included within the definition of the transmission medium.

[0147] The information, signals, etc. described in this disclosure may be represented using any of a variety of different technologies. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc., which may be referred to throughout the above description, may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0148] In addition, terms described in the present disclosure and terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol may be a signal (signaling). Also, a signal may be a message. Also, a component carrier (CC) may be referred to as a carrier frequency, a cell, a frequency carrier, or the like.

[0149] The terms "system" and "network" used in the present disclosure are used interchangeably.

[0150] Also, information, parameters, etc. described in the present disclosure may be represented using absolute values, relative values from a predetermined value, or corresponding other information. For example, a radio resource may be indicated by an index.

[0151] The names used for the above-described parameters are not limiting in any way. Furthermore, mathematical formulas and the like using these parameters may be different from those explicitly disclosed in the present disclosure. Since various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, the various names assigned to these various channels and information elements are not limiting in any way.

[0152] In the present disclosure, terms such as "Base Station (BS)", "radio base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", and "component carrier" may be used interchangeably. The base station may also be referred to by terms such as macro cell, small cell, femto cell, and pico cell.

[0153] A base station can accommodate one or more (e.g., three) cells (also called sectors). When a base station accommodates multiple cells, the entire coverage area of the base station can be divided into multiple smaller areas, and each smaller area can also provide communication services by a base station subsystem (e.g., a small indoor base station (Remote Radio Head: RRH)).

[0154] The term "cell" or "sector" refers to a part or the whole of the coverage area of at least one of the base station and the base station subsystem that provides communication services within this coverage.

[0155] In the present disclosure, terms such as "Mobile Station (MS)", "user terminal", "User Equipment (UE)", and "terminal" may be used interchangeably.

[0156] A mobile station may also be referred to by those skilled in the art as a subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable term.

[0157] At least one of the base station and the mobile station may be referred to as a transmitting device, a receiving device, a communication device, etc. Note that at least one of the base station and the mobile station may be a device mounted on a moving body, the moving body itself, etc. The moving body may be a vehicle (e.g., a car, an airplane, etc.), a moving body that moves unmanned (e.g., a drone, a self-driving car, etc.), or a robot (humanoid or unmanned). Note that at least one of the base station and the mobile station also includes a device that does not necessarily move during communication operation. For example, at least one of the base station and the mobile station may be an Internet of Things (IoT) device such as a sensor.

[0158] Also, the base station in the present disclosure may be read as a mobile station (user terminal, the same hereinafter). For example, each aspect / embodiment of the present disclosure may be applied to a configuration in which communication between the base station and the mobile station is replaced with communication between a plurality of mobile stations (which may be referred to as, for example, Device-to-Device (D2D), Vehicle-to-Everything (V2X), etc.). In this case, the functions of the base station may be configured as functions of the mobile station. Also, terms such as "uplink" and "downlink" may be read as terms corresponding to communication between terminals (e.g., "side"). For example, an uplink channel, a downlink channel, etc. may be read as a side channel.

[0159] Similarly, the mobile station in the present disclosure may be read as a base station. In this case, the functions of the mobile station may be configured as functions of the base station. The wireless frame may be composed of one or more frames in the time domain. Each of the one or more frames in the time domain may be called a subframe. The subframe may further be composed of one or more slots in the time domain. The subframe may have a fixed time length (e.g., 1 ms) that does not depend on numerology.

[0160] Numerology may be communication parameters applied to at least one of transmission and reception of a certain signal or channel. Numerology may indicate, for example, at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, wireless frame configuration, specific filtering processing performed by a transceiver in the frequency domain, specific windowing processing performed by a transceiver in the time domain, etc.

[0161] The slot may be composed of one or more symbols (Orthogonal Frequency Division Multiplexing (OFDM) symbols, Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols, etc.) in the time domain. The slot may be a time unit based on numerology.

[0162] A slot may include a plurality of mini-slots. Each mini-slot may be composed of one or more symbols in the time domain. Also, a mini-slot may be called a sub-slot. A mini-slot may be composed of a smaller number of symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may be called a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be called a PDSCH (or PUSCH) mapping type B.

[0163] A radio frame, a sub-frame, a slot, a mini-slot, and a symbol all represent time units when transmitting a signal. Different names corresponding to each of them may also be used.

[0164] For example, one sub-frame may be called a transmission time interval (TTI), a plurality of consecutive sub-frames may be called a TTI, or one slot or one mini-slot may be called a TTI. That is, at least one of the sub-frame and the TTI may be a sub-frame (1 ms) in the existing LTE, or 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, a mini-slot, etc. instead of a sub-frame.

[0165] Here, the TTI refers to, for example, the minimum time unit of scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as the frequency bandwidth and transmission power that can be used in each user terminal) to each user terminal in TTI units. Note that the definition of the TTI is not limited to this.

[0166] The TTI may be a transmission time unit such as a channel-coded data packet (transport block), a code block, a codeword, etc., or may be a processing unit such as scheduling and link adaptation. When the TTI is given, the time interval (e.g., the number of symbols) in which a transport block, a code block, a codeword, etc. are actually mapped may be shorter than the TTI.

[0167] When one slot or one mini-slot is called a TTI, one or more TTIs (i.e., one or more slots or one or more mini-slots) may be the minimum time unit for scheduling. Also, the number of slots (mini-slot numbers) constituting the minimum time unit for the scheduling may be controlled.

[0168] A TTI having a time length of 1 ms may be called a normal TTI (TTI in LTE Rel.8 - 12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a slot, etc. A TTI shorter than the normal TTI may be called a shortened TTI, a short TTI, a partial TTI (partial or fractional TTI), a shortened subframe, a short subframe, a mini-slot, a sub-slot, a slot, etc.

[0169] Note that the long TTI (e.g., the normal TTI, the subframe, etc.) may be read as a TTI having a time length exceeding 1 ms, and the short TTI (e.g., the shortened TTI, etc.) may be read as a TTI having a TTI length less than that of the long TTI and equal to or more than 1 ms.

[0170] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and in the frequency domain, it may include one or a plurality of consecutive subcarriers. The number of subcarriers included in the RB may be the same regardless of the numerology, for example, it may be 12. The number of subcarriers included in the RB may be determined based on the numerology.

[0171] Also, the time domain of the RB may include one or more symbols, and may be the length of 1 slot, 1 mini-slot, 1 sub-frame, or 1 TTI. 1 TTI, 1 sub-frame, etc. may each be composed of one or more resource blocks.

[0172] Note that one or more RBs may be referred to as physical resource blocks (PRBs), sub-carrier groups (SCGs), resource element groups (REGs), PRB pairs, RB pairs, etc.

[0173] Also, a resource block may be composed of one or more resource elements (REs). For example, 1 RE may be a radio resource area of 1 sub-carrier and 1 symbol.

[0174] A bandwidth part (BWP) (which may also be called a partial bandwidth, etc.) may represent a subset of consecutive common resource blocks (common RBs) for a certain numerology in a certain carrier. Here, the common RB may be specified by the index of the RB based on the common reference point of the carrier. The PRB is defined in a certain BWP and may be numbered within the BWP.

[0175] The BWP may include a BWP for UL (UL BWP) and a BWP for DL (DL BWP). For a UE, one or more BWPs may be set within one carrier.

[0176] At least one of the set BWPs may be active, and the UE may not be assumed to transmit and receive a predetermined signal / channel outside the active BWP. Note that "cell", "carrier", etc. in the present disclosure may be read as "BWP".

[0177] The structures such as the above-described radio frames, sub-frames, slots, mini-slots, and symbols are merely illustrative. For example, the number of sub-frames included in a radio frame, the number of slots per sub-frame or radio frame, the number of mini-slots included in a slot, the number of symbols and RBs included in a slot or mini-slot, the number of sub-carriers included in an RB, and the number of symbols, symbol length, Cyclic Prefix (CP) length, etc. within a TTI can be variously changed.

[0178] The terms "connected" and "coupled", or any variations thereof, mean any direct or indirect connection or coupling between two or more elements, and can include the presence of one or more intermediate elements between two elements "connected" or "coupled" to each other. The coupling or connection between elements can be physical, logical, or a combination thereof. For example, "connected" may be read as "accessed". As used in this disclosure, two elements can be considered to be "connected" or "coupled" to each other using at least one of one or more electric wires, cables, and printed electrical connections, and also, by way of some non-limiting and non-exhaustive examples, electromagnetic energy having wavelengths in the radio frequency region, microwave region, and optical (both visible and invisible) region.

[0179] The reference signal can also be abbreviated as Reference Signal (RS) and may be called a Pilot depending on the applicable standard.

[0180] As used in this disclosure, the description "based on" does not mean "based only on" unless otherwise specified. In other words, the description "based on" means both "based only on" and "based at least on".

[0181] In the configurations of the above-described respective devices, the "means" may be replaced with "section", "circuit", "device", etc.

[0182] Any reference to an element using designations such as "first", "second", etc. used in the present disclosure does not generally limit the quantity or order of those elements. These designations may be used in the present disclosure as a convenient way to distinguish between two or more elements. Thus, a reference to a first and a second element does not mean that only two elements may be employed there, or that the first element must precede the second element in any way.

[0183] In the present disclosure, when terms such as "include", "including" and their variants are used, these terms are intended to be inclusive, like the term "comprising". Further, the term "or" used in the present disclosure is intended not to be an exclusive disjunction.

[0184] In the present disclosure, for example, when articles are added by translation, like a, an and the in English, the present disclosure may include that the nouns following these articles are in the plural form.

[0185] As used in this disclosure, the terms "determining" and "deciding" may encompass a wide variety of actions. "Determining" and "deciding" may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up (e.g., searching a table, database, or other data structure), ascertaining, and considering something as having been "determined" or "decided". Also, "determining" and "deciding" may include considering something as having been "determined" or "decided" based on receiving (e.g., receiving information), transmitting (e.g., transmitting information), inputting, outputting, accessing (e.g., accessing data in memory), etc. Further, "determining" and "deciding" may include considering something as having been "determined" or "decided" based on resolving, selecting, choosing, establishing, comparing, etc. That is, "determining" and "deciding" may include considering that some action has been "determined" or "decided". Also, "determining (deciding)" may be read as "assuming", "expecting", "considering", etc.

[0186] In this disclosure, the term "A and B are different" may mean that "A and B are different from each other". Note that the term may also mean that "A and B are each different from C". Terms such as "separated", "coupled", etc. may also be interpreted in the same way as "different".

[0187] As described in detail above, it is obvious to those skilled in the art that the present disclosure is not limited to the embodiments described in the present disclosure. The present disclosure can be implemented in modified and changed forms without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the description of the present disclosure is for illustrative purposes only and has no restrictive meaning for the present disclosure.
