[0032] [0032] In the following, modalities of the present invention will be described.
[0033] [0033] Figure 1 is a conceptual diagram of a radio communication system in accordance with the present modality. In Figure 1, a radio communication system consists of terminal devices 1A to 1C, and a base station device 3. From this point on, terminal devices 1A to 1C are each also called terminal device 1 .
[0034] [0034] The terminal device 1 is also called a user terminal, a mobile station device, a communication terminal, a mobile device, a terminal, a user equipment (UE - "User Equipment") and a mobile station (MS - "Mobile Station"). The base station handset 3 is also called a radio base station handset, a base station, a radio base station, a fixed station, a Node B, or NodeB (NB), an evolved Node B, or NodeB (eNB), a transceiver base station (BTS), a base station (BS), an NR Node B, or NR NodeB (NR NB), an NNB, a transmit and receive point (TRP) or a new generation B node, or gNB.
[0035] [0035] In Figure 1, in a radio communication between terminal 1 and the base station device 3, orthogonal frequency division multiplexing (OFDM - "Orthogonal Frequency Division Multiplexing") can be used consisting of a cyclic prefix (CP - "Cyclic Prefix"), single-carrier frequency division multiplexing (SC-FDM - "Single-Carrier Frequency Division Multiplexing"), discrete Fourier transform propagation OFDM (DFT-S-OFDM - "Discrete Fourier Transform Spread ") or multiplexing by multi-port code division (MC-CDM).
[0036] [0036] In addition, in Figure 1, in the radio communication between the terminal device 1 and the base station device 3, the UFMC (universal filtered multiport), F-OFDM (filtered OFDM), Windowed OFDM (OFDM) techniques can be used window) or FBMC (multiport with filter bank).
[0037] [0037] It should be noted that the present modality will be described using the OFDM symbol with the assumption that a transmission scheme is OFDM, including the use of any other transmission scheme in one aspect of the present invention.
[0038] [0038] In addition, in Figure 1, in the radio communication between the terminal device 1 and the base station device 3, the CP cannot be used, or the transmission scheme described above with the addition of zeros can be used instead of the CP. In addition, the CP or the addition of zeros can be added either forward or backward.
[0039] [0039] In Figure 1, in a radio communication between terminal 1 and the base station device 3, orthogonal frequency division multiplexing (OFDM - "Orthogonal Frequency Division Multiplexing") can be used consisting of a cyclic prefix (CP - "Cyclic Prefix"), single-carrier frequency division multiplexing (SC-FDM - "Single-Carrier Frequency Division Multiplexing"), discrete Fourier transform propagation OFDM (DFT-S-OFDM - "Discrete Fourier Transform Spread ") or multiplexing by multi-port code division (MC-CDM).
[0040] [0040] In Figure 1, the following physical channels are used for radio communication between terminal device 1 and the base station device 3. - Physical broadcast channel (PBCH - "Physical Broadcast Channel") - Physical control channel ( PCCH) - Shared physical channel (PSCH)
[0041] [0041] The PBCH is used to broadcast a block of essential information or master information block (MIB - "Master Information Block"), a block of essential information (EIB - "Essential")
[0042] [0042] The PCCH is used to transmit uplink control information (UCI - "Uplink Control Information") in a case of uplink radio communication (radio communication from terminal device 1 to base station device 3). Here, uplink control information can consist of channel state information (CSI) used to indicate a downlink channel state. Uplink control information can consist of a scheduling request (SR - "Scheduling Request") used to request a resource for UL-SCH ("Uplink Shared Channel"). Uplink control information may consist of a hybrid automatic repeat request confirmation (HARQ-ACK - "Hybrid Automatic Repeat request ACKnowledgment"). The HARQ-ACK can indicate a HARQ-ACK for downlink data (transport block, media access control protocol data unit (MAC PDU) or a downlink shared channel (DL-SCH - "Downlink- Shared Channel ")).
[0043] [0043] In addition, the PCCH is used to transmit downlink control (DCI) information in a downlink radio communication case (radio communication from the base station device 3 to the terminal device 1). Here, one or more DCIs (which may be called DCI formats) are defined for the transmission of downlink control information. In other words, a field for downlink control information is defined as DCI and is mapped to bits of information.
[0044] [0044] For example, the DCI can be defined to consist of information indicating whether a signal included in a scheduled PSCH corresponds to a downlink radio or an uplink radio.
[0045] [0045] For example, the DCI can be defined to consist of information indicating a downlink transmission period included in the scheduled PSCH.
[0046] [0046] For example, DCI can be defined to consist of information indicating an uplink transmission period included in the scheduled PSCH.
[0047] [0047] For example, the DCI can be defined to consist of information indicating a timing for transmission of the HARQ-ACK that concerns a scheduled PSCH (for example, the number of symbols from the last symbol included in the PSCH to the symbol transmission of HARQ-ACK).
[0048] [0048] For example, the DCI can be defined to consist of information indicating a downlink transmission period, a gap, and an uplink transmission period included in a scheduled PSCH.
[0049] [0049] For example, DCI can be defined to be used in scheduling a downlink radio PSCH in a cell (transmission of a downlink transport block).
[0050] [0050] For example, DCI can be defined to be used in scheduling an uplink radio communication PSCH in a cell (transmission of an uplink transport block).
[0051] [0051] Here, the DCI consists of information related to the scheduling of the PSCH in a case in which the PSCH consists of uplink or downlink. Here, the DCI for the downlink is also called downlink grant, or downlink assignment. Here, the DCI for the uplink is also called an uplink grant, or uplink assignment.
[0052] [0052] PSCH is used to transmit uplink data (uplink shared channel (UL-SCH - "Uplink Shared CHannel")) or downlink data (downlink shared channel (DL-SCH - "Downlink Shared) CHannel ")) from the media access control (MAC -" Medium Access Control "). In a downlink case, the PSCH is also used to transmit system information (SI - "System Information"), a random access response (RAR - "Random Access Response") and the like. In an uplink case, the PSCH can be used to transmit HARQ-ACK and / or CSI together with the uplink data. PSCH can be used to transmit only CSI or only HARQ-ACK and CSI. In other words, the PSCH can be used to transmit only the UCI.
[0053] [0053] Here, the base station apparatus 3 and the terminal apparatus 1 exchange (transmit and / or receive) signals with each other in their respective higher layers. For example, in a radio resource control (RRC) layer, the base station device 3 and terminal device 1 can transmit and / or receive RRC signaling (also called a radio resource control message (message RRC information), or radio resource control information (RRC information)). In a media access control (MAC) layer, the base station handset 3 and the terminal handset 1 can transmit and / or receive a MAC control element. Here, the system information (broadcasting signals or the like), the RRC signaling and / or the MAC control element are also called the higher layer signaling.
[0054] [0054] PSCH can also be used to transmit system information, RRC signaling and the MAC control element. Here, the RRC signaling transmitted from base station 3 can be a signaling common to multiple terminals 1 in a cell. The RRC signaling transmitted from base station 3 can be signaling dedicated to a particular terminal 1 (also called dedicated signaling). In other words, the terminal-specific (EU-specific) information can be transmitted via signaling dedicated to the given terminal
[0055] [0055] It should be noted that although the same designations of PCCH and PSCH are commonly used for both the downlink and the uplink, different channels can be defined for the downlink and the uplink.
[0056] [0056] For example, a shared downlink channel can be called a physical downlink shared channel (PDSCH - "Physical Downlink Shared CHannel"). A shared uplink channel can be called a physical uplink shared channel (PUSCH - "Physical Uplink Shared CHannel"). A downlink control channel can be called a physical downlink control channel (PDCCH - "Physical Downlink Control Channel"). An uplink control channel can be called a physical uplink control channel (PUCCH - "Physical Uplink Control CHannel").
[0057] [0057] In Figure 1, physical downlink signals mentioned below are used for downlink radio communication. Here, the physical downlink signals are not used to transmit the information emitted from the upper layers, but are used by the physical layer. - Synchronization signal (SS) - Reference signal (RS)
[0058] [0058] The synchronization signal may consist of a primary synchronization signal (PSS - "Primary Synchronization Signal") and / or a secondary synchronization signal (SSS - "Second Synchronization Signal"). A cell ID can be detected using PSS and SSS.
[0059] [0059] The synchronization signal is used so that the terminal device 1 establishes a synchronization in the frequency domain and / or in the time domain in the downlink. Here, the synchronization signal can be used for terminal device 1 to select a precoding or a beam in the precoding or beam formation performed by the base station apparatus 3.
[0060] [0060] A reference signal is used for terminal device 1 to perform channel compensation on a physical channel. Here, the reference signal can be used for terminal device 1 to calculate downlink CSIs. The reference signal can be used for numerology as a radio parameter or spacing between subcarriers, or it is used for fine synchronization that allows to obtain an FFT (fast Fourier transform) synchronization window.
[0061] [0061] According to the present modality, at least one of the following downlink reference signals is used. - Demodulation Reference Signal (DMRS) - Channel State Information Reference Signal (CSI-RS - "Channel State Information Reference Signal") - Phase Tracking Reference Signal (PTRS - " Phase Tracking Reference Signal ")
[0062] [0062] DMRS is used to demodulate a modulated signal. It should be noted that two types of reference signals can be defined as the DMRS: a reference signal to demodulate the PBCH, and a reference signal to demodulate the PSCH, or both reference signals can be called DMRS. CSI-RS is used for measuring channel status (CSI) and / or beam management information. The PTRS is used to track a phase according to the movement of the terminal or similar. The MRS can be used to measure the reception quality of multiple base station devices for transfers between cells. The reference signal can be defined as a reference signal for phase noise compensation.
[0063] [0063] The physical downlink channels and / or the physical downlink signals are collectively called a downlink signal. The physical uplink channels and / or the physical uplink signals are collectively called an uplink signal. The physical downlink channels and / or the physical uplink channels are collectively called a physical channel. The physical downlink signals and / or the physical uplink signals are collectively called a physical signal.
[0064] [0064] BCH, UL-SCH and DL-SCH are transport channels. A channel used in the Medium Access Control (MAC) layer is called a transport channel. A unit of the transport channel used in the MAC layer is also called a transport block (TB - "Transport Block") and / or a protocol data unit (PDU - "Protocol Data Unit") of MAC. A hybrid auto-repeat request (HARQ - "Hybrid
[0065] [0065] The reference signal can also be used to measure radio resources (RRM - "Radio Resource Measurement"). The reference signal can also be used for beam management.
[0066] [0066] The beam management can be a procedure of the base station apparatus 3 and / or of the terminal apparatus 1 to correlate the directionality of an analog and / or digital beam in a transmission apparatus (the base station apparatus 3 on the downlink and the terminal device 1 on the uplink) with the directionality of an analog and / or digital beam on a receiving device (the terminal device 1 on the downlink and the base station device 3 on the uplink) to capture a beam gain.
[0067] [0067] It should be noted that the procedure described below can be included as a procedure for constituting, configuring or establishing a beam pair link. - Beam selection - Beam refinement - Beam recovery
[0068] [0068] For example, beam selection can be a procedure for selecting a beam in communication between the base station device 3 and the terminal device 1. Beam refinement can be a procedure for selecting a beam that has a higher gain or changing a beam to an optimal beam between the base station device 3 and the terminal device 1 according to the movement of the terminal device 1. Beam recovery can be a procedure to reselect the beam in a case where the quality of the communication link decreases due to the blockage caused by a blocking object, a passing human being, or the like, in communications between the base station apparatus 3 and the terminal apparatus 1.
[0069] [0069] Beam management can consist of beam selection and beam refinement. It should be noted that the beam recovery can consist of the following procedures: - the detection of a beam failure - the discovery of a new beam - the transmission of a beam recovery request - the monitoring of a response to a request beam recovery
[0070] [0070] For example, CSI-RS or a sync signal (eg SSS) can be used in a sync signal block, or an assumption of almost the same location (QCL - "Quasi Co- Location ") for terminal device 1 for selecting a transmission beam for base station device 3.
[0071] [0071] In a case where the long-term ownership of a channel in which a symbol on one antenna port is carried can be estimated from a channel in which a symbol from another antenna port is carried, the two antenna ports are considered to have almost the same location (QCL). The long-term property of the channel consists of at least one of a delay spread, Doppler spread, Doppler shift, an average gain or an average delay. For example, in the case where an antenna port 1 and an antenna port 2 are in the state of almost the same location (QCL) in relation to the average delay, this means that the reception delay of the antenna port 2 can be estimated from the reception delay of the antenna port 1.
[0072] [0072] QCL can also be expanded for beam management. In this way, the spatially expanded QCL can be defined again. For example, the long-term property of a channel under the assumption of spatial QCL can be an angle of arrival (AoA - "Angle of Arrival") or a Zenith angle of arrival (ZoA - "Zenith angle of Arrival"), or similar ) and / or an angle spread (for example, an angle spread (ASA) or a Zenith angle spread (ZSA - "Zenith angle Spread of Arrival")), a angle of departure (AoD - "Angle of Departure" or ZoD, or the like) and either an angle angle spread of the angle of departure (for example, an angle spread of the angle (ASD - "Angle Spread of Departure"), or a Zenith departure angle spreading (ZSS - "Zenith angle Spread of Departure")), or spatial correlation on a radio link or a channel.
[0073] [0073] According to this method, an operation of the base station apparatus 3 and the terminal apparatus 1 equivalent to the beam management can be defined as a beam management based on the assumption of spatial QCL and radio resources (time and / or frequency).
[0074] [0074] The subframe will now be described. The subframe in the present modality can also be called a resource unit, a radio frame, a period of time, or an interval of time.
[0075] [0075] Figure 2 is a diagram illustrating a schematic configuration of a downlink gap according to a first embodiment of the present invention. Each radio frame is 10 ms long. In addition, each radio frame consists of 10 subframes and X intervals. In other words, the length of a subframe is 1 ms. For each interval, the time period is defined based on spacing between subcarriers. For example, in the case where a spacing between subcarriers of an OFDM symbol is 15 kHz and normal cyclic prefixes (NCPs) are used, X = 7 or X = 14, and X = 7 and X = 14 correspond to 0, 5 ms and 1 ms, respectively. In the case where the spacing between subcarriers is 60 kHz, X = 7 or X = 14, and X = 7 or X = 14 correspond to 0.125 ms and 0.25 ms, respectively. Figure 2 illustrates a case of X = 7 as an example. It should be noted that a case of X = 14 can be configured in a similar way by expanding the case where X = 7. The uplink interval can be defined in a similar way, and the downlink interval and the link interval ascending can be defined separately.
[0076] [0076] The signal or physical channel transmitted in each of the intervals can be represented by a grid of resources. The resource grid is defined by several subcarriers and multiple OFDM symbols. The number of subcarriers that make up a range depends on each bandwidth of a cell's downward and upward links. Each element within the resource grid is called a resource element. The resource element can be identified using a subcarrier number and an OFDM symbol number.
[0077] [0077] A resource block is used to express the mapping of a specific physical downlink channel (such as PDSCH) or a specific physical uplink channel (such as PUSCH) to resource elements. For the resource block, a virtual resource block and a physical resource block are defined. A given physical uplink channel is first mapped to a block of virtual resources. After that, the virtual resource block is mapped to a physical resource block. In a case in which the number X of OFDM symbols included in a range is 7 and NCPs are used, a block of physical resources is defined by seven consecutive OFDM symbols in the time domain and by 12 consecutive subcarriers in the frequency domain. Thus, a physical resource block consists of (7 × 12) resource elements. In the case of extended CPs (ECPs), a block of physical resources is defined, for example, by 6 consecutive OFDM symbols in the time domain and by 12 consecutive subcarriers in the frequency domain. Thus, a physical resource block consists of (6 × 12) resource elements. In this case, a block of physical resources corresponds to an interval in the time domain and corresponds to 180 kHz in the frequency domain in the case where the spacing between subcarriers is 15 kHz (720 kHz in the case of 60 kHz). The blocks of physical resources are numbered from 0 (zero) in the frequency domain.
[0078] [0078] The subframe, the interval and a mini-interval will now be described. Figure 3 is a diagram illustrating the relationship between the subframe, the interval and the mini-interval in the time domain. As shown in Figure 3, three types of time units are defined. The subframe is 1 ms regardless of the spacing between subcarriers. The number of OFDM symbols in the range is 7 or 14, and the length of the range depends on the spacing between subcarriers. Here, in the case of spacing between 15 kHz subcarriers, 14 OFDM symbols are included in a subframe. Thus, assuming that the spacing between subcarriers is Δf (kHz), the interval length can be defined as 0.5 / (Δf / 15) ms when the number of OFDM symbols that constitute an interval is 7. Here, Δf can be defined by the spacing between subcarriers (kHz). When the number of OFDM symbols that make up an interval is 7, the interval length can be set to 1 / (∆f / 15) ms. Here, Δf can be defined by the spacing between subcarriers (kHz). The interval length can be defined as X / 14 / (Δf / 15) ms, where X is the number of OFDM symbols included in an interval.
[0079] [0079] The mini-interval (which can be called a subinterval) is a unit of time that consists of OFDM symbols whose number is less than the number of OFDM symbols included in the interval. Figure 3 illustrates, by way of example, a case in which the mini-interval consists of two OFDM symbols. The OFDM symbols in the mini range can correspond to the timing of the OFDM symbols that make up the range. It should be noted that the minimum scheduling unit can be an interval or a mini-interval. Figure 4 is a diagram illustrating examples of the range or subframe. Here, an example is illustrated as a case in which the interval length is 0.5 ms in a 15 kHz spacing between subcarriers. In Figure 4, D represents the downlink and U represents the downlink. As shown in Figure 4, for a certain period of time (for example, the minimum period of time to be allocated to a UE in the system), the subframe can consist of one or more of: - a downlink part (duration) - a gap, or - an uplink part (duration).
[0080] [0080] The sub-frame (a) of Figure 4 illustrates an example in which, for a certain period of time (also called, for example, a minimum unit of time resource that can be allocated to a UE, a unit of time , or similar, and also a group of multiple minimum time resource units can be called a time unit), all time resources are used for downlink transmission, and a subframe (b) of Figure 4 illustrates that the initial time feature is used for uplink scheduling, for example, through the PCCH and that an uplink signal is transmitted after a gap for a PCCH processing delay, a time to switch from a downlink for an uplink, and the transmission of an uplink signal through a gap for generating a transmission signal. The subframe (c) of the Figure
[0081] [0081] The downlink part and the uplink part described above can consist of multiple OFDM symbols, as is the case with LTE.
[0082] [0082] Figure 5 is a diagram illustrating an example of beam formation. Multiple antenna elements are connected to a transceiver unit (TXRU) 10. The phase is controlled using a phase shifter 11 for each antenna element and a transmission is carried out from an antenna element 12, thus allowing a beam for a transmission signal is directed in any direction. Typically, the TXRU can be defined as an antenna port, and only the antenna port can be defined for terminal device 1. Controlling the phase shifter 11 allows you to configure directionality in any direction. In this way, the base station device 3 can communicate with the terminal device 1 using a high gain beam.
[0083] [0083] Figure 6 is a diagram illustrating an example of a sync signal block, a sync signal burst and a set of sync signal bursts. Figure 6 illustrates an example in which a set of burst bursts consists of a burst burst, a burst burst consists of three burst blocks, and each burst block consists of a OFDM symbol.
[0084] [0084] The set of sync signal bursts consists of at least one burst of sync signal, and a burst of sync signal consists of at least one sync signal block. The synchronization signal block consists of a unit of time that consists of one or more consecutive OFDM symbols. It should be noted that the time unit included in the sync signal block may be shorter than the length of the OFDM symbol.
[0085] [0085] The set of bursts of synchronization signal can be transmitted periodically. For example, a periodicity used for initial access and a periodicity configured for a connected terminal device (connected state or RRC_Connected state) can be defined. The periodicity configured for the connected terminal device (connected state or RRC_Connected state) can be configured in the RRC layer. The periodicity configured for the connected terminal (connected state or RRC_Connected state) can be a periodicity of a radio resource in the time domain during which the transmission is potentially performed and, in practice, whether the transmission should be performed during the periodicity can be determined by the base station handset 3. The frequency used for initial access can be predefined in the specifications or the like.
[0086] [0086] The subcarrier spacing for the PSS and / or SSS used for initial access is predefined in the specifications, and a set of burst bursts configured for a connected terminal device can be determined based on a frame number (SFN - "System Frame Number"). In addition, an initial position of the set of burst bursts (limit) can be determined based on SFN and periodicity.
[0087] [0087] It can be assumed that the same beam is applied to bursts of sync signal or blocks of sync signal that have the same relative time within each of the multiple sets of bursts of sync signal. It can be assumed that antenna ports for burst bursts or burst signal blocks that have the same relative time within each of the multiple sets of burst bursts have almost the same location (QCL) relative to the average delay, Doppler shift and spatial correlation.
[0088] [0088] Among the multiple sets of burst bursts, the relative time position in which the burst burst is mapped can be fixed.
[0089] [0089] The burst of burst may consist of at least one burst of burst in the burst of burst. It can be assumed that an antenna port for a sync signal block at a certain relative time within a burst of sync signal has almost the same location (QCL) as an antenna port for a sync signal block at the same time. same relative time within another burst of synchronization signal in relation to average delay, Doppler shift and spatial correlation.
[0090] [0090] In the case where multiple bursts of sync are included in a set of bursts of sync signal, the relative time intervals between the multiple bursts of sync signal in the set of bursts of sync signal can be fixed. For example, in a case where a set of burst bursts has a periodicity of 15 ms and three bursts of burst signal are included in the burst set, burst bursts can be mapped at 5 ms intervals. .
[0091] [0091] The synchronization signal block may consist of at least one of the PSS, the SSS or the PBCH. PSS, SSS and PBCH can be multiplexed in the time domain (TDM) or multiplexed in the frequency domain (FDM). At least one of the PSS, SSS or PBCH can be included in the synchronization signal block.
[0092] [0092] Figure 7 is a diagram illustrating examples of a PSS, SSS and PBCH multiplexing method in the synchronization signal block. Figure 7 (a) is a diagram illustrating an example in which a PSS, an SSS and a PBCH are multiplexed over time in a synchronization signal block. Figure 7 (b) illustrates a case in which a PSS, an SSS and a PBCH are multiplexed over time in a synchronization signal block and a broadband width is used for a PBCH (for example, the number of subcarriers of PBCH or resource elements is greater than the number of PSSs and / or SSSs). Figure 7 (c) is a diagram illustrating an example in which a PBCH, a PSS, an SSS and a PBCH are multiplexed over time in a synchronization signal block. Here, the first PBCH and the last PBCH in the sync signal block can be the same. The temporal order of the PSS, SSS and PBCHs can be PSS, SSS, PBCH and PBCH. Figure 7 (d) is a diagram illustrating an example in which the same signal sequence is transmitted twice in the order of a PSS, a
[0093] [0093] The number of sync signal blocks can be defined, for example, as the number of sync signal blocks within the sync signal burst, or within the set of sync signal bursts, or within the periodicity of the sync signal blocks. The number of sync signal blocks can indicate the number of beam groups for selecting cells within the sync signal burst, within the set of sync signal bursts or within the periodicity of the sync signal blocks. Here, the beam group can be defined as the number of sync signal blocks included in the sync signal burst or set of sync signal bursts, or the periodicity of the sync signal blocks, or it can be the number different bundles.
[0094] [0094] In the case where different beams are used for the synchronization signal blocks transmitted using any two antenna ports, the two antenna ports can be defined as not being of almost the same location (QCL) for parameters space, the antenna ports being used for the transmission of sync signal blocks within the sync signal burst, or within the periodicity of sync signal blocks. The beam can also be defined as a transmit or receive filter configuration.
[0095] [0095] Spatial parameters may consist of at least one or more of the following: - Spatial correlation. - Reception angle (arrival angle (AoA) and / or Zenith arrival angle (ZoA)) - Reception angle spread (arrival angle spread (ASA) and / or arrival angle spread)
[0096] [0096] Sync signal blocks may indicate the number of beams within the beam group or sync signal burst or within the set of sync signal bursts or within the periodicity of sync signal blocks. For example, in Figure 7 (a), Figure 7 (b), Figure 7 (c), Figure 7 (d) and Figure 7 (f), in a case where a beam is applied to the sync signal block, the number of beams within the burst of burst, or within the set of burst of burst, or within the periodicity of burst blocks corresponds to the number of burst blocks transmitted in the burst of burst. In Figure 7 (e), the sync signal blocks are transmitted twice using the same beam, and thus the number of beams can be the number of sync signal blocks / 2.
[0097] [0097] The number of sync signal blocks within the sync signal burst predefined in the specifications can indicate the maximum value of the number of potential sync signal blocks within the sync signal burst. A sync signal burst time period predefined in the specifications can be defined with an integer multiple of an interval length or a subframe length, or it can be defined based on an interval length or a subframe length, such as half or a third of the gap length or the length of the subframe. The time period of the burst burst can be defined based on the length of the OFDM symbol or the minimum time (Ts) instead of the length of the interval or the length of the subframe.
[0098] [0098] A method to indicate the number of sync signal blocks in the burst of sync signal will be described below. The number of synchronization signal blocks can be indicated for terminal device 1 using an identity to generate PSS and / or SSS.
[0099] [0099] PSS and SSS are generated by an M sequence or a Gold sequence (which can be a PN sequence). In this case, an initial value of a shift register can be determined based on at least the number of sync signal blocks in the sync signal burst. The initial value of the shift register can also be based on the cell ID or a value based on the cell ID.
[00100] [00100] In the case where the PSS and / or SSS also include a coverage code (for example, a cyclic shift or a Hadamard sequence), a parameter to determine the amount of cyclic shift or a row index of the Hadamard sequence can be determined based on at least the number of sync signal blocks within the sync burst. The parameter for determining the amount of cyclic shift or row index of the Hadamard sequence can be further based on the cell ID or the value based on the cell ID.
[00101] [00101] The number of sync signal blocks within the sync signal burst can be included in the MIB transmitted in the PBCH or in the system information.
[00102] [00102] The terminal device 1 measures the quality of reception (for example, RSRP, RSRQ, RS-SINR, and the like, obtained by measuring RRM) in a cell, based on the number of synchronization signal blocks in the burst of synchronization signal. In this case, the measured values can be an average of the sync signal blocks in the sync signal burst.
[00103] [00103] The measurement for cell selection can be an average value for X (X can be 1, X can be an integer greater than or equal to 2) sync signal blocks in the sync signal burst. In this case, the number of sync blocks in the sync burst does not need to be indicated.
[00104] [00104] In this way, the bits can be reduced by indicating only the number of multiple sync signal blocks instead of indicating the sync signal block configuration.
[00105] [00105] The MIB transmitted in the PBCH may consist of time indexes of sync signal blocks within the sync signal burst, within the set of sync signal bursts, or within the periodicity of the sync signal blocks. The separate RRC signaling can be used to notify the timing indexes of sync signal blocks within the sync signal burst, within the set of sync signal bursts, or within the periodicity of the sync signal blocks.
[00106] [00106] Time indices can be notified by using the ID of a third signal (for example, a tertiary synchronization signal (TSS) or a channel status information reference signal (CSI-RS - "Channel Cell-specific State Information Reference Signal "). Here, the cell-specific CSI-RS can be signaled with the MIB included in the PBCH or the SIB included in the PDSCH (for example, it can be one or more of the parameters consisting of the periodicity of CSI-RS, resources (consists of time, frequency and code) and the number of antenna ports. It should be noted that the TSS to be transmitted can be multiplexed in time or multiplexed in frequency with PSS, SSS and PBCH in the sync signal block TSS can also be defined as a signal in the sync signal block CSI-RS can also be transmitted in the sync signal block.
[00107] [00107] The MIB transmitted in the PBCH can indicate a method of mapping sync signal blocks within the sync signal burst, within the set of sync signal bursts, or within the periodicity of sync signal blocks (local (located / contiguous) or discrete (distributed / non-contiguous)). The mapping method can also be indicated with a bit. Information about the mapping method can be notified by separate RRC signaling.
[00108] [00108] Figure 8 illustrates examples of a method for mapping synchronization signal blocks. Figure 8 (a) illustrates an example in which synchronization signal blocks are locally mapped in a time domain from a periodicity limit. Figure 8 (b) illustrates an example in which the synchronization signal blocks are discretely mapped within the periodicity in the time domain. Here, the periodicity can be configured as the periodicity of burst bursts or the periodicity of sets of burst bursts, or the periodicity of burst blocks, or the periodicity of burst signals.
[00109] [00109] In Figure 8 (a), the synchronization signal blocks can be temporally defined locally. For example, in the case where the number of potential sync signal blocks is L, terminal device 1 can assume L contiguous sync signal blocks. The terminal apparatus 1 can receive an indicated number of sync signal blocks included in the L potential sync signal blocks or sync signal blocks at indicated locations. In Figure 8 (b), the terminal device 1 can assume the discretely mapped timing blocks that are included in the potential L timing blocks. The terminal apparatus 1 can assume an indicated number of sync signal blocks included in the potential sync signal blocks or sync signal blocks at indicated locations. A burst of sync signal consists of multiple blocks of sync signal that can be locally or discretely mapped. Terminal device 1 can perform measurements assuming contiguous sync signal blocks, or it can eliminate resources for the sync signal blocks of the PDSCH resource elements.
[00110] [00110] The value of L can be defined in the specifications. The value of L can be defined in the specifications based on the frequency range. It should be noted that "local" can mean that the sync signal blocks included in sync signal block mapping candidates in the sync signal burst set or the sync signal burst are locally mapped. "Local" can mean that the sync signal blocks are mapped to intervals located in the set of sync bursts or in the sync signal burst. "Local" may mean that a burst of sync signal or a set of multiple sync signal blocks is locally mapped into the set of burst burst signals.
[00111] [00111] In Figure 8 (b), the time position of the sync signal block or the sync signal burst assumed by the terminal device 1 can be adjusted based on the L number of potential sync signal blocks or signal bursts. synchronization. For example, assume that the number of OFDM symbols within a periodicity is NSC, the number of symbols included in the sync signal block or sync signal burst is S (in the case of the sync signal burst, S can the number of OFDM symbols included in the time domain in which the burst bursts are mapped), and the total number of time positions in which the burst blocks or burst bursts can be mapped is Nss, where Nss is represented by the equation below. Equation 1
[00112] [00112] Of the candidate Nss, the temporal position of the l-th potential (l = 0 for L-1 or l = 1 for L) block of synchronization signal or burst of synchronization signal can be defined as in the equation below. The equation below is for an example in which the sync signal blocks are mapped at equal intervals. Certainly, the equation can be similarly defined for bursts of synchronization signal. Equation 2
[00113] [00113] n (l) indicates the temporal position of the l-th synchronization signal block. It should be noted that l is an index for each time resource for a corresponding sync signal block, but it can be represented as an index of an OFDM symbol or an index of an interval. An equation can be used in which the time position is defined to be aligned with a limit of an interval (for example, the beginning of the interval or the end of the interval), for the value determined by Equation 2. For example, the temporal position can be defined as the beginning of the interval closest to the position represented by Equation 2.
[00114] [00114] Terminal device 1 can receive a specified number of actual sync signal blocks included in the L sync signal blocks or actual sync signal blocks in the time position.
[00115] [00115] The time position can be defined by replacing L in Equation 2 with the indicated number of synchronization signal blocks.
[00116] [00116] Figure 9 illustrates examples in which sync signal blocks are mapped to local intervals or discrete intervals, such as a configuration of local or discrete sync signal blocks. Figure 9 (a) illustrates an example in which a PSS, an SSS and a PBCH are temporally mapped in the event that local mapping is indicated. As shown in Figure 9 (a), a synchronization signal block is mapped to each of the contiguous intervals. Here, the start of the sync signal block is mapped to the third OFDM symbol in the range. The OFDM symbol to which the first sync signal block is mapped can be defined in the specifications.
[00117] [00117] Figure 9 (b) illustrates an example of mapping to discrete intervals. Here, it should be assumed that the number of intervals included in the frequency of the sync signal blocks is Nslot, the number of symbols included in the sync signal block is S and the total number of time positions in which sync signal blocks can be mapped is N SS, NSS being represented by the equation below. Equation 3
[00118] [00118] Of the candidate Nss, an interval within the periodicity consists of the potential l-th (l = 0 for L-1 or l = 1 for L) block of synchronization signal can be defined as in the equation below. Equation 4
[00119] [00119] In this way, the timing positions of sync signal blocks can be determined by means of one or more information indicating whether the sync signal blocks are local or discrete, the frequency of the sync signal blocks, the number of sync signal blocks included in the sync signal block frequency and a maximum number within a predefined sync signal block frequency. In a case of discrete mapping, the time interval between sync signal blocks or the periodicity of sync signal bursts can be predefined as described above or notified in the PBCH or with the SIB or a separate RRC signal.
[00120] [00120] The periodicity of the sync signal blocks can be a set of sync signal bursts or a sync signal burst. It should be noted that the periodicity of the sync signal blocks and the number of sync signal blocks included in the periodicity of the sync signal blocks can be configured by RRC signaling. These types of information can be indicated with the MIB included in the PBCH. In the event that the periodicity of the synchronization signal blocks is not configured, a predefined periodicity (for example, a standard periodicity of 20 milliseconds) can be used. Terminal device 1 can assume the maximum number within the predefined timing of the sync signal blocks in a case where the number of sync signal blocks included in the timing of the sync signal blocks is not configured. It should be noted that the function not configured by the RRC signaling may consist of a case in which a message indicating that the function is not configured or a case in which a message indicating that the function is configured is not included in the RRC signaling. A bitmap can be used to notify the time position. For example, bit 1 can indicate a time position at which a sync signal block has been transmitted, and bit 0 can indicate a time position at which no sync signal block has been transmitted.
[00121] [00121] The terminal device 1 can assume that bits for logical synchronization signal blocks are set using a bitmap of length L and correspond to discrete or local physical time positions. For example, terminal apparatus 1 can assume physical time positions, based on the bits for the sync signal blocks represented using the L-bit bitmap and the information described above from local or discrete mapping.
[00122] [00122] In the example described above, although the sync signal blocks are locally and discretely mapped, local and discrete mappings can be done using, as a unit, a sync signal burst or multiple signal blocks synchronization. In another possible method, for example, four sync signal blocks are mapped locally as a unit, and the unit is mapped discretely. The bitmap can be formed by using, as a unit, a burst of sync signal or multiple blocks of sync signal.
[00123] [00123] No downlink shared physical channel symbol is mapped to resource elements used for (corresponding to) temporal positions of the synchronization signal blocks configured as described above.
[00124] [00124] The PBCH encoding will be described below. Here, in the description, it is assumed that the periodicity of the sync signal blocks (the periodicity of the sync signals, the periodicity of the sync signal bursts or the periodicity of the sets of sync signal bursts) is 20 milliseconds and that the PBCH transmission time interval (TTI) is 80 milliseconds.
[00125] [00125] MIB code bits transmitted in the PBCH are shuffled by the Gold sequence. Here, the M sequence (or the M sequence constituting the Gold sequence) can be initialized every 80 milliseconds by the cell ID. For example, in the case where a system frame number (SFN) is assumed to be nf, the M sequence can be initialized using the cell ID detected in the PSS or SSS in each frame that satisfies the nf mod ratio 8 = 0.
[00126] [00126] The MIB code bits transmitted in the PBCH are shuffled by the Gold sequence. Here, the M sequence (or the M sequence constituting the Gold sequence) can be initialized every 80 milliseconds using the cell ID and timing indices of the sync signal blocks.
[00127] [00127] A sync signal block ID (SS block identifier) can be defined using the time index or the ID of each sync signal block, based on the cell ID detected in the PSS, in the SSS, TSS or PBCH, and the M sequence can be initialized by the sync signal block ID.
[00128] [00128] Figure 10 illustrates examples of a relationship between time indices and intervals related to the timing positions of the sync signal blocks in the case where the sync signal is transmitted locally. Figure 10 (a) illustrates an example in which a sync signal block is mapped at one interval and four sync signal blocks are mapped at four intervals. Thus, in the case where a sync signal block is mapped in an interval, the index is determined for each interval or for each sync signal block in the interval, for the time index. Figure 10 (b) illustrates an example in which multiple sync signal blocks can be mapped at one interval and eight sync signal blocks are mapped at four intervals. In the example in Figure 10 (b), two sync signal blocks are mapped at an interval and indexed from the beginning in the sequence. In this way, the time index can indicate the ID of each block of synchronization signal and can be defined as an indication of the index of a beam.
[00129] [00129] The time position of the sync signal block (sync signal) can be an interval index, the time position of the interval or a time position within the interval or the time index of the sync signal block.
[00130] [00130] An example will be described below in which the base station device 3 sets up the TTS described previously on the terminal device 1. On initial access, the terminal device 1 receives synchronization signal blocks with a predefined periodicity (for example, a standard period of 20 milliseconds). After terminal device 1 "encapsulates" in or connects to base station device 3, base station device 3 can indicate the periodicity of sync signal blocks (or burst bursts or sets of burst bursts). synchronization signal) effectively transmitted over the network.
[00131] [00131] At that time, the base station device 3 can configure whether the TSS is included in the synchronization signal blocks. For example, in a transfer, in a case where terminal device 1 performs RRM measurements related to another cell (for example, received reference signal power (RSRP) and received reference signal quality (RSRQ), synchronization signal reference reception (SS-RSRP), and CSI-RSRP (CSI-
[00132] [00132] It should be noted that the reception of the synchronization signal blocks from other cells using the TSS can be configured through the RRC signaling, or it can be indicated to the terminal device 1 through a broadcast signal.
[00133] [00133] In the case where the TSS is multiplexed by time multiplexing, any of the following orders (order of the number of OFDM symbol) can be used for multiplexing in the synchronization signal blocks. - PSS, SSS, PBCH, TSS - PSS, PBCH, SSS, TSS - SSS, PSS, PBCH, TSS - SSS, PBCH, PSS, TSS - PBCH, PSS, SSS, TSS - PBCH, SSS, PSS, TSS - TSS , PSS, SSS, PBCH - TSS, PSS, PBCH, SSS - TSS, SSS, PSS, PBCH - TSS, SSS, PBCH, PSS - TSS, PBCH, PSS, SSS - TSS, PBCH, SSS, PSS
[00134] [00134] It should be noted that, in a case where the PBCH is provided in multiple symbols, the PBCH can be assigned to the contiguous symbols, or it can be assigned to the temporally distant positions within the sync signal block. For example, PBCH can be allocated in the order of PBCH, PSS, SSS and PBCH.
[00135] [00135] Figure 11 illustrates examples in which the TSS is multiplexed.
[00136] [00136] Here, terminal device 1 can perform initial access only with the PSS, SSS and PBCH, and measure the reception quality in the server cell that corresponds to the frequency corresponding to a measurement object using the PSS, SSS and TSS in the synchronization signal block with the TSS configured at the time of transfer.
[00137] [00137] TSS and CSI-RS can be configured by RRC signaling. At this time, in a case where TSS is configured, terminal device 1 receives PSS, SSS and TSS in the synchronization signal block. In the event that TSS is not configured, terminal device 1 receives PSS, SSS and TSS in the synchronization signal block.
[00138] [00138] Terminal device 1 performs measurements, based on PSS, SSS and TSS in the case where TSS is configured, and performs measurements based on PSS and SSS in case TSS is not configured.
[00139] [00139] Here, measurements can consist of the received power measurement per beam (for example, L1-RSRP) and can consist of RRM measurements for the cell level.
[00140] [00140] In a case where TSS is configured, the sync signal block ID (SS block identifier) can be defined based on PSS, SSS and TSS, and, in the case where the third signal sync signal is not configured, the sync signal block identity (SS block identifier) can be set based on the PSS and SSS.
[00141] [00141] In a case where TSS is configured for terminal device 1, no PDSCH symbol is mapped to the resource elements used in PSS, SSS and TSS, and in the case where TSS is not configured, Downlink shared physical channel symbols are not mapped to the resource elements used in PSS and SSS.
[00142] [00142] In the case of receiving information related to the timing positions of the sync signal blocks within the periodicity of the sync signal blocks, terminal device 1 can assume that the PSS, SSS and SSS are included in the time positions of the sync signal blocks received by the sync signal blocks, and you can apply the operation described above.
[00143] [00143] The measurements will be described below. Terminal device 1 can receive the measurement object and perform measurements, based on information that indicates whether the periodicity of the sync signal blocks included in the measurement object is the same or different from the periodicity of the sync signal blocks in the cell server that corresponds to the frequency corresponding to the measurement object. For example, in a case where the periodicity of the sync signal blocks is set to be equal to the periodicity of the sync signal blocks in the server cell that corresponds to the frequency corresponding to the measurement object, terminal device 1 assumes the configured periodicity to the server cell and performs the measurements in blocks of synchronization signal from a neighboring cell. In a case where the periodicity of sync signal blocks or the maximum number of sync signal blocks or the actual number of sync signal blocks is configured to be different from the periodicity or the maximum or actual number of blocks of the synchronization signal in the server cell that corresponds to the frequency corresponding to the measurement object, the terminal device 1 assumes a standard periodicity or a maximum or a real number of synchronization signal blocks and performs the measurements in the synchronization signal blocks of the neighboring cell.
[00144] [00144] Information related to the time positions within the sync signal can be received, and measurements can be performed based on information that indicates whether the time positions of the sync signal blocks included in the measurement object are the same or different of the temporal positions in the server cell corresponds to the frequency corresponding to the measurement object. For example, in a case where the information related to the time positions in the synchronization signal is configured to be the same as the information in the server cell, the terminal device 1 can assume the positions of the devices in the time configured for the server cell and perform measurements on the neighbor cell sync signal blocks. In the event that the information related to the time positions in the synchronization signal are configured to be the same as the information in the server cell corresponds to the frequency corresponding to the measurement object, the terminal device 1 can assume predefined time positions and carry out the measurements in neighbor cell sync signal blocks. The information indicating whether the time positions of the synchronization signal blocks included in the measurement object are the same or different from the time positions in the server cell corresponds to the frequency corresponding to the measurement object can be information indicating whether the time positions of the signal signal blocks synchronization are included in the measurement object.
[00145] [00145] The measurement object can be defined as an object of the measurements to be performed by the terminal device. For intra-frequency and inter-frequency measurements, the measurement object can be defined as an NR carrier frequency. For measuring access to evolved universal terrestrial radio (EUTRA, also called LTE) between radio access technologies (inter-RAT), the measurement object can be defined as an EUTRA carrier frequency or a set of cells in a EUTRA carrier frequency. For the measurement of access to universal terrestrial radio (UTRA, WCDMA (trade name), also called HSPA) among radio access technologies (inter-RAT), the measurement object can be defined as a set of cells at a frequency UTRA carrier.
[00146] [00146] The measurement configuration consisting of the measurement object may consist of information (timing signal measurement periodicity information) indicating the timing of the timing signal blocks. The measurement object may consist of information indicating whether the periodicity of the synchronization signal blocks with the frequency (and / or the cell) to be measured is assumed to be the same as, or different from, the measurement periodicity information the synchronization block.
[00147] [00147] The measurement configuration (measurement configuration) consisting of the measurement object may consist of multiple measurement periodicity information of synchronization signal blocks, and the measurement object may consist of information indicating which measurement measurement periodicity information synchronization signal block must correspond to the frequency of synchronization signal blocks with the frequency (and / or cell) to be measured.
[00148] [00148] The measurement object may consist of measurement resource information for the synchronization signal blocks available for RSRP and RSRQ measurements for the neighboring cell at a carrier frequency indicated by a carrier frequency included in the measurement object. It should be noted that terminal device 1 can assume that, in all cells included in the cell list included in the measurement object, the measurement capabilities for the sync signal blocks are the same as the measurement capabilities for the blocks synchronization signal in a given server cell (for example, PCell). It should be noted that the measurement resources for the sync signal blocks can consist of one or more of the periodicity, the maximum number of sync signal blocks, and the actual number of sync signal blocks.
[00149] [00149] The measurement object can consist of information related to the measurement resources for the synchronization signal blocks in the neighboring cell at a certain frequency. For example, a bit can be set and implemented as described below.
[00150] [00150] - 0: the neighboring cell does not have the same measurement resources for the synchronization signal blocks as those of the server cell,
[00151] [00151] - 1: the measurement resources for the synchronization signal blocks in all neighboring cells are identical to the measurement resources for the synchronization signal blocks in the server cell.
[00152] [00152] The terminal device 1 performs the measurements, based on the configurations described above, and provides measurement results for the base station device 3.
[00153] [00153] One aspect of the present modality can be operated in carrier aggregation or a double connectivity with radio access technologies (RATs - "Radio Access Technologies"), such as LTE and LTE-A / LTE-A Pro. In this case , the aspect can be used for some or all cells or groups of cells, or carriers or groups of carriers (for example, primary cells (PCells),
[00154] [00154] The device configurations according to the present modality will be described below. Here, an example is illustrated in which CP-OFDM is applied as a downlink radio transmission scheme and CP DFTS-OFDM (SC-FDM) is applied as an uplink radio transmission scheme.
[00155] [00155] Figure 12 is a schematic block diagram that illustrates a configuration of the terminal apparatus 1 according to the present modality. As shown in Figure 12, terminal apparatus 1 is configured to consist of a higher layer processing unit 101, a controller 103, a receiver 105, a transmitter 107 and a transmit and / or receive antenna 109. The higher layer processing 101 is configured to consist of a radio resource control unit 1011, a scheduling information interpretation unit 1013, and a channel state information reporting (CSI) control unit 1015.
