Description

Technical Field

[0001] The present disclosure relates to a terminal utilizing a satellite positioning system. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) has standardized the fifth generation mobile communication system (also referred to as 5G, New Radio (NR) or Next Generation (NG)), and has also standardized the next generation mobile communication system referred to as Beyond 5G, 5G Evolution or 6G.

[0003] In 3GPP version 18, the performance improvement of IoT (Internet of Things)-NTN (Non-Terrestrial Network) was discussed (Non-Patent Document 1). IoT is a technology that connects devices such as sensors to a network and sends and receives information obtained by the device through the network. In addition, the device can also be mounted on a UE (User Equipment) and connected to the network via the UE. NTN is a technology that uses aircraft such as satellites installed in the sky as an intermediary in the communication between the base station and the UE, so that communication can be carried out even in areas where radio waves are difficult to reach.

[0006] Non-patent document 1: "Revised WID on IoT NTN enhancements", RP-221806, 3GPP TSGRAN Meeting #96, 3GPP, June 6-9, 2022 Summary of the invention

[0007] However, in the communication between the base station and the UE, there are cases where a satellite positioning system such as GNSS (Global Navigation Satellite System) is used. For example, the calculation of the TA (Timing Advance) value in the UL (Uplink) transmission of the UE requires the location information of the UE. Therefore, when the UE moves, it is necessary to receive a wireless signal from the satellite positioning system and update the location information of the UE. In addition, the location information of the UE is shared by the UE and the base station.

[0008] In particular, in IoT-NTN, in addition to using relatively low-speed communication standards such as LTE-M (Machine), NB (Narrow Band)-IoT, and eMTC (enhanced Machine Type Communication), there is a tendency for the time involved in the UE's UL transmission to be longer because aircraft installed in the sky will also be used as intermediaries.

[0009] However, in the connection state of the radio resource control layer which is a prerequisite for UL transmission, there is a problem of how to receive a radio signal from a satellite positioning system and update the location information of the UE.

[0010] Therefore, the present invention is made in view of such a situation, and its object is to provide a terminal that can receive a wireless signal from a satellite positioning system and update the location information of the UE in a connected state of a radio resource control layer.

[0011] One disclosed method is a terminal, wherein the terminal comprises: a sending unit 210, which performs UL transmission in a connected state of a wireless resource control layer; a receiving unit 210, which receives the wireless signal in a measurement gap set for receiving the wireless signal from a satellite positioning system; and a control unit 270, which obtains the terminal's location information from the wireless signal.

[0025] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the same or similar reference numerals are given to the same functions and structures, and their descriptions will be appropriately omitted.

[0026] [Implementation Method]

[0027] (1) Structure of wireless communication system

[0028] like Figure 1 As shown in FIG. 1 , the wireless communication system 10 includes a next generation radio access network 20 (Next Generation-Radio Access Network, hereinafter referred to as NG-RAN 20) including a base station 100 and a terminal 200 (hereinafter referred to as UE 200). NG-RAN 20 may be simply referred to as a “network”. In addition, the specific structure of the wireless communication system 10, such as the number of base stations 100 and UE 200, is not limited to Figure 1 Example shown.

[0029] The wireless communication system 10 of the embodiment includes an aircraft 150 that mediates communication between a base station 100 and a UE 200 , and a satellite positioning system S that transmits a wireless signal for acquiring position information of the UE 200 .

[0030] The wireless communication system 10 is a wireless communication system that complies with a method called 5G. On the other hand, the wireless communication system 10 may also be a wireless communication system that complies with a method called Beyond 5G, 5G Evolution, or 6G.

[0031] The wireless communication system 10 of the embodiment may also correspond to communication standards such as LTE-M, NB-IoT, and eMTC.

[0032] The base station 100 is a wireless base station that transmits and receives wireless signals to and from the UE 200. The base station 100 of the embodiment transmits and receives wireless signals to and from the UE 200 via the aircraft 150 described later. In addition, the base station 100 of the embodiment is, for example, a gNB, but may also be an eNB.

[0033] The base station 100 of the embodiment may also update the location information of the UE 200 based on the auxiliary information described later. In addition, the base station 100 may transmit the updated location information of the UE 200 to the UE 200 .

[0034] The aircraft 150 is, for example, a satellite, but may also be a high altitude platform station (HAPS) mounted on an airship, a balloon, etc. The aircraft 150 serves as a relay station in the communication between the base station 100 and the UE 200 .

[0035] The satellite positioning system S is, for example, a GNSS, but may also be a satellite positioning system constituting a GNSS such as a GPS (Global Positioning System). The satellite positioning system S is composed of a plurality of satellites that transmit wireless signals to the ground. The number of satellites constituting the satellite positioning system S is, for example, 4. On the ground, the distance to each satellite is calculated based on the time taken to receive the wireless signal transmitted from each satellite. Thus, the location where the wireless signal from the satellite is received can be determined. In this way, the satellite positioning system S transmits a wireless signal for determining the receiving location on the ground.

[0036] UE200 is a wireless communication terminal that transmits and receives wireless signals with the base station 100. The UE200 of the embodiment transmits and receives wireless signals with the base station 100 via the aircraft 150. In addition, the UE200 of the embodiment can obtain the location information of the UE200 based on the wireless signal sent from the satellite positioning system S. In addition, the UE200 of the embodiment can also be assumed to be mounted on a mobile body such as a UAV (Unmanned Aerial Vehicle) and move.

[0037] (2) Terminal structure

[0038] like Figure 2 As shown, UE 200 includes a radio signal transceiver unit 210 , an amplifier unit 220 , a modulation and demodulation unit 230 , a control signal and reference signal processing unit 240 , an encoding and decoding unit 250 , a data transceiver unit 260 , and a control unit 270 .

[0039] The wireless signal transceiver 210 transmits and receives wireless signals to and from the base station 100. The wireless signal transceiver 210 may constitute a transmitter that transmits wireless signals and a receiver that receives wireless signals.

[0040] The wireless signal transceiver 210 of the embodiment transmits and receives wireless signals between the base station 100 via the aircraft 150. In addition, the wireless signal transceiver 210 of the embodiment receives wireless signals from the satellite positioning system S.

[0041] The wireless signal transceiver 210 of the embodiment transmits the location information of the UE 200 described later to the base station 100. In addition, the wireless signal transceiver 210 of the embodiment transmits the auxiliary information described later to the base station 100.

[0042] The amplifier unit 220 is composed of a PA (Power Amplifier) / LNA (Low Noise Amplifier) ​​etc. The amplifier unit 220 amplifies the wireless signal output from the modulation and demodulation unit 230 to a predetermined power level. The amplifier unit 220 amplifies the wireless signal output from the wireless signal transmission and reception unit 210 .

[0043] The modem unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication destination (base station 100 or other base stations). In the modem unit 230, cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) / discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) can be applied. In addition, DFT-S-OFDM can be used not only for UL but also for DL.

[0044] The control signal / reference signal processing unit 240 performs processing related to various control signals / reference signals and other radio signals transmitted and received by the UE 200 .

[0045] The control signal and reference signal processing unit 240 of the embodiment acquires position information and auxiliary information. Hereinafter, the position information will be described first, and then the auxiliary information will be described.

[0046] (Location Information)

[0047] The control signal and reference signal processing unit 240 obtains the location information of UE200 based on the wireless signal from the satellite positioning system S. Specifically, based on the transmission time information contained in the wireless signal from the satellite positioning system S and the reception time information of the wireless signal, the distance to each satellite constituting the satellite positioning system S is calculated, and the location information of UE200 is obtained based on the distance.

[0048] like Figure 3 As shown, in the location information of UE200, a validity period (validity duration, corresponding to the validity period of GNSS in the figure) can also be set. The validity period of the location information of UE200 can be set by UE200 or by the base station 100. The wireless signal transceiver unit 210 performs UL transmission during the validity period (corresponding to the transmission part in the figure). The control signal / reference signal processing unit 240 can also re-acquire the location information of UE200 based on the validity period. The validity period can be, for example, 10s, 20s, 30s, 40s, 50s, 60s, 5min, 10min, 15min, 20min, 25min, 30min, 60min, 90min, 120min, infinity.

[0049] For example, the location information of UE 200 is requested in order to calculate the TA value in communication with base station 100. Therefore, the location information of UE 200 is acquired before starting UL transmission to base station 100. In addition, the location information of UE 200 is shared between UE 200 and base station 100.

[0050] On the other hand, the location information of UE200 may also be updated in UL transmission to base station 100. This is because it is preferable to update the location information of UE200 in UL transmission when UE200 moves, etc. However, UE200 cannot perform UL transmission and obtain location information based on wireless signals from satellite positioning system S at the same time.

[0051] In the case of updating the location information of UE200 in UL transmission, such as Figure 3As shown, the measurement gap (hereinafter referred to as MG, corresponding to the GNSS measurement gap in the figure) for receiving the wireless signal from the satellite positioning system S is set by various control signals sent from the base station 100. In addition, MG can also be called TDW (Time Domain Window).

[0052] MG can be set / activated / indicated by RRC (Radio Resource Control) / MAC (Medium Access Control) CE (Control Element) / DCI (Downlink Control Information) which are various control signals sent from base station 100. In addition, MG can be set by RRC and activated by MAC CE, or can be set by RRC and indicated by DCI. In addition, indication can also be replaced by trigger.

[0053] In addition, UL transmission is based on the connection state of the radio resource control layer (corresponding to the RRC_CONNECTED mode in the figure), so the MG is also set in the connection state of the radio resource control layer. By setting the MG, it is possible to receive a wireless signal from the satellite positioning system S in the connection state of the radio resource control layer. As shown below, the MG includes parameters such as period, offset, and period. In addition, "period" and "periodicity" can also be replaced with each other.

[0054] MG can also Figure 4 As shown in the figure, the MG period can be set as a periodic / semi-persistent time resource. In this case, the period of the MG can also be set according to the validity period of the location information of UE200, the auxiliary information described later, the transmission conditions, etc. The period of the MG is the same as the validity period of the location information of UE200, for example, it can be 10s, 20s, 30s, 40s, 50s, 60s, 5min, 10min, 15min, 20min, 25min, 30min, 60min, 90min, 120min, infinity. On the other hand, the MG can also be set as shown in the figure. Figure 5 As shown, it is indicated aperiodicy.

[0055] MG can also be set by different control signals according to the type of time domain (i.e., periodic / semi-persistent / aperiodic: periodic / semi-persistent / aperiodic). For example, periodic MG can be set by RRC, semi-persistent MG can be set by RRC and activated by MAC CE, and aperiodic can be set by RRC MG and indicated by DCI.

[0056] The MG offset may also be set or indicated. For example, the offset may be applied as specified in Section 5.5.2.9 of 3GPP TS38.331. That is, a predetermined time offset may be applied to the MG at a predetermined timing according to the setting or indication of the MG offset, and the start timing of the UL transmission of the UE 200 may also be made consistent with the start timing of the MG. For example, since UL transmission is not performed in the MG, Figure 6 As shown, it is also possible to offset to the boundary of the segment. Thus, there is no need to worry about UL transmission being interrupted in the middle of the segment. In this case, although the valid periods of the location information of the MG and the UE 200 overlap, the MG takes priority and UL transmission is not performed during the period of overlap with the MG. In addition, the number of offset subframes / time slots / code elements can also be set by the base station 100.

[0057] The duration of MG may also be set according to UE capability information such as UE capability (UE Capability).

[0058] The cycle / offset / period of the above-mentioned MG can also be set by different control signals. For example, the cycle and period can be set by RRC, and the offset can be indicated by DCI. In addition, multiple MGs with different cycles / offsets / periods can be set by RRC, and the cycle / offset / period of any MG can be activated / indicated by MAC CE / DCI.

[0059] The setting or instruction of the MG may also be requested by the UE 200. That is, the base station 100 may set or instruct the MG according to the request of the UE 200.

[0060] The request for setting or indicating the MG by the UE 200 may be performed in a periodic, semi-persistent, or aperiodic manner.

[0061] The request of UE 200 to set or instruct the MG may be made through control signals such as RRC / MAC CE / UCI (Uplink Control Information), or may be made through different control signals according to periodic / semi-persistent / aperiodic.

[0062] The request of UE 200 to MG for setting or instruction may be as follows.

[0063] Opt1 (1-bit request: 1-bit request)

[0064] The request for MG configuration or indication may also be associated with the cycle / offset / period of the MG. Prior to this, the base station 100 may provide the UE 200 with a configuration parameter of a MG.

[0065] Opt2 (Request with indication of which MG configuration: request with indication of which MG configuration)

[0066] The base station 100 provides the UE 200 with the configuration parameters of the plurality of MGs, and the UE 200 may request the configuration or indication of one of the MGs (the UE 200 indicates, for example, the index of the MG).

[0067] Opt3 (Request with concrete parameters)

[0068] The request for setting or indicating the MG may also request specific values ​​of the MG's period / offset / duration / time domain type (i.e., periodic / semi-persistent / aperiodic). For example, regarding the period, the same value as the valid period of the GNSS may be a candidate value. For example, regarding the period, the request may also be based on the UE capability.

[0069] Furthermore, in the setting or instruction of the MG, different parameters (eg, cycle / offset / duration) may be requested by different control signals.

[0070] The request of UE 200 to set or instruct MG may be triggered by the following conditions.

[0071] Alt 1 sets a periodic timer that is triggered by the expiration of the timer.

[0072] Alt 2 is triggered when RLF (Radio Link Failure) occurs

[0073] Alt 3 is triggered when the location information of UE 200 or the auxiliary information described below changes by more than a threshold.

[0074] In addition, in the case of Alt 2, UE 200 may report the validity period of the updated location information of UE 200 to base station 100 at the same time as making a request for setting or indicating the MG.

[0075] The processing of the UL transmission segment in the case where the MG overlaps with one or more segments of the UL transmission of UE200 is described. As described in the case of offsetting the MG, the MG takes precedence over the valid period of the location information of UE200. That is, the MG takes precedence over the UL transmission performed during the valid period of the location information of UE200. As a result, when the UL transmission is scheduled in the MG, the UL transmission is not performed. The following describes the processing of the UL transmission segment that is not performed due to overlap with the MG.

[0076] like Figure 7 As shown, in the case where the MG overlaps with the segment transmitted by UL, the MG overlaps with the entire segment, and the segment overlapping with the MG is discarded as a whole. In this case, UE200 does not expect that only part of the segment overlaps and is discarded. That is, UE200 expects that the setting of MG is a setting that takes into account the start timing of UL transmission and the transmission period. In addition, being discarded can mean that UL transmission is not performed in MG, UL transmission is not performed even after MG, and it can also mean that transmission is performed after MG.

[0077] In this case, the duration of MG may be set from the end of a certain segment to the end of another segment (see Figure 7 In addition, the MG period can also be set from between two segments to between two other segments (refer to Figure 7 In addition, the duration of MG can also be set from between two segments to the end of the other segment (see Figure 7 ).

[0078] like Figure 8 As shown, in the case where the MG overlaps a portion of the segment transmitted by the UL, a portion of the segment overlapping with the MG is discarded or postponed. In the case of being discarded, the UE 200 counts the portion of the segment overlapping with the MG (or the corresponding time slot) as the number of transmissions. In the case of postponement, the UE 200 does not count the portion of the segment overlapping with the MG (or the corresponding time slot) as the number of transmissions. In addition, postponement means that the signal that was not transmitted in the MG is transmitted after the MG.

[0079] In the case where part of a segment is discarded due to overlap with an MG,

[0080] Discarding can also be set periodic / semi-persistent / aperiodic.

[0081] · Abandonment can be set / activated / indicated via RRC / MAC CE / DCI.

[0082] The number of discarded time slots may be preset or may be set by the base station 100 .

[0083] The period for instructing to discard may be preset to, for example, every 2 segments, every 3 segments, etc., or may be set by the base station 100 .

[0084] The start of discarding may be set in advance, for example, at the time when a discarding instruction is received, or may be set by the base station 100 .

[0085] In the case where part of the segment is delayed due to overlap with MG,

[0086] MG can also be set to periodic / semi-persistent / aperiodic.

[0087] MG can be configured / activated / indicated via RRC / MAC CE / DCI.

[0088] The period (number of time slots) of MG may be set in advance or may be set by the base station 100 .

[0089] The period of MG may be preset, for example, to every 2 segments, every 3 segments, etc., or may be set by the base station 100 .

[0090] The start of MG may be set in advance, for example, at the time when the instruction of MG is received, or may be set by the base station 100 .

[0091] Furthermore, when a portion of the segment is delayed due to overlap with the MG, the duration (number of time slots) of the segment transmitted by UL after the MG may be, for example, as follows: Fig. 9 Furthermore, it is assumed that one segment consists of 10 time slots, and the 9th and 10th time slots are extended.

[0092] Opt 1 The 9th and 10th time slots sent by the UL after the MG are considered as the next segment (segment 2-2 in the figure)

[0093] Opt 2 The 9th to 18th time slots sent by UL after MG are regarded as the next segment (segment 2-2 + segment 3-1 in the figure)

[0094] The above describes the processing of the segmentation of UL transmission that is not performed due to overlap with MG, but such processing can also be applied to the case where the MG is set and the UL transmission is scheduled independently and the MG and UL transmission overlap. On the other hand, in order to apply such processing, the MG can be set first and the UL transmission can be scheduled according to the MG.

[0095] (Auxiliary information)

[0096] The control signal and reference signal processing unit 240 acquires auxiliary information. Specifically, the control signal and reference signal processing unit 240 acquires auxiliary information from a sensor (not shown) mounted on the UE 200 or the like.

[0097] The auxiliary information is information related to the movement of UE200. Specifically, the auxiliary information may include at least one of the moving speed of UE200, the change in the moving speed of UE200, the derivative of the change in the moving speed of UE200, and the moving trajectory of UE200. The obtained auxiliary information (or the auxiliary information sent to the base station 100 as described later) may be predetermined, or may be set or indicated by the base station 100. In addition, in the latter case, the base station 100 may also request the UE200 to send the auxiliary information.

[0098] The auxiliary information may be the value itself obtained by the control signal / reference signal processing unit 240, a predicted value calculated based on the value obtained by the control signal / reference signal processing unit 240, a value corresponding to a predetermined time interval, or a value corresponding to a predetermined timing.

[0099] The timing for acquiring the auxiliary information may also be specified as follows.

[0100] Explicitly reported by UE 200. For example, SFN and / or subframe number are signaled.

[0101] Implicitly determined as the transmission time (reporting time) of UE 200

[0102] Implicitly determined as the reception time of the base station 100

[0103] The predicted value is set to be a predicted value in a period including the time when the auxiliary information is obtained. Fig.10 As shown, when the time of obtaining the auxiliary information is t1, the period serving as a basis for calculating the prediction value may be the period T0 from t1 to t0 in the past, the period T1 from t1 to t2 in the future, or the period T2 spanning the past and the future and including t1.

[0104] In the auxiliary information, the validity period may be set in the same manner as the location information of the UE 200. The validity period of the auxiliary information may be set by the UE 200 or by the base station 100. The control signal / reference signal processing unit 240 may also reacquire the auxiliary information based on the validity period. The validity period may be, for example, 10 s, 20 s, 30 s, 40 s, 50 s, 60 s, 5 min, 10 min, 15 min, 20 min, 25 min, 30 min, 60 min, 90 min, 120 min, or infinity.

[0105] The start timing of the effective period set in the auxiliary information may be started as shown below.

[0106] Explicitly reported by UE 200. For example, SFN and / or subframe number are signaled.

[0107] Implicitly determined as the transmission time (reporting time) of UE 200

[0108] Implicitly determined as N slots / ms / s / min according to the transmission time (reporting time) of UE 200

[0109] Implicitly determined as the reception time of the base station 100

[0110] The length of the effective period set in the auxiliary information may also be set as shown below.

[0111] It may also be explicitly reported by UE 200. It may also be preset. It may also be set by an upper layer parameter.

[0112] The validity period may be the same as that of the location information of the UE 200, or may be different from that of the location information of the UE 200.

[0113] The auxiliary information may also be sent to the base station 100 via a control signal such as RRC / MAC CE / UCI.

[0114] The auxiliary information may be transmitted from the UE 200 to the base station 100 at the following timing.

[0115] Alt 1 after initial access

[0116] Alt 2 sets a periodic timer, and the situation is triggered by the expiration of the timer

[0117] Alt 3 auxiliary information is changed

[0118] Alt 4 is set / activated / indicated by the network's set signaling

[0119] Alt 5 N symbols / slots / ms / s before the expiration of the validity period of the location information of UE 200

[0120] The auxiliary information is information for updating the location information of UE 200. Thus, even when the MG is not set and the location information of UE 200 cannot be reacquired based on the wireless signal received from the satellite positioning system S, the location information of UE 200 can be updated.

[0121] The location information of UE200 may also be updated by the base station 100. In this case, the wireless signal transceiver 210 sends the location information and auxiliary information of UE200 to the base station 100. The base station 100 updates the location information of UE200 according to the auxiliary information, and sends the updated location information of UE200 to UE200. Thus, the updated location information of UE200 can be shared between UE200 and the base station 100.

[0122] The location information of UE 200 may be updated multiple times. In this case, a valid period may be set for each updated location information of UE 200. When the valid period is not long enough, it is preferable to perform multiple updates.

[0123] The updated location information of UE200 may be sent via control signals such as RRC / MAC CE / DCI.

[0124] In the case shown below, the UE 200 may expect to receive updated location information of the UE 200 .

[0125] Alt1 N symbols / slots / ms / m before the validity period of the location information of UE 200 expires

[0126] Alt2 After UE200 sends N symbols / slots / ms / m of update request

[0127] Alt3 After UE200 sends N symbols / slots / ms / m of auxiliary information

[0128] Alt 4 sets a timer that will expire before

[0129] On the other hand, the update of the location information of UE200 may also be performed by the control signal / reference signal processing unit 240. In this case, the wireless signal transceiver unit 210 may send the updated location information or auxiliary information of UE200 to the base station 100. Thus, the updated location information of UE200 can be shared between UE200 and the base station 100. In addition, the capability information of UE200 such as UECapability may also be defined so that the location information of UE200 can be derived from at least one of the following information.

[0130] Validity period of the location information of UE 200

[0131] Time required to obtain the location information of UE 200

[0132] UE200 speed parameters

[0133] UE200's movement trajectory

[0134] The encoding / decoding unit 250 performs data segmentation / concatenation, channel encoding / decoding, and the like for each predetermined communication destination (the base station 100 or another base station).

[0135] Specifically, the encoding / decoding unit 250 divides the data output from the data transceiver unit 260 into predetermined sizes and performs channel coding on the divided data. In addition, the encoding / decoding unit 250 decodes the data output from the modulation / demodulation unit 230 and concatenates the decoded data.

[0136] The data transceiver 260 transmits and receives data such as a protocol data unit (PDU) and a service data unit (SDU) with the base station 100. The data transceiver 260 may also constitute a transmitting unit for transmitting data and a receiving unit for receiving data.

[0137] Specifically, the data transceiver 260 performs PDU / SDU assembly / disassembly in multiple layers (media access control layer, radio link control layer, packet data convergence protocol layer, etc.) In addition, the data transceiver 260 performs data error correction and retransmission control based on HARQ (Hybrid Automatic Repeat Request).

[0138] The control unit 270 controls each functional block constituting the UE 200. That is, it can be said that the function of the control unit in the claims is realized by each functional block constituting the UE 200, such as the control signal / reference signal processing unit 240 of the embodiment.

[0139] (3) Operation of wireless communication system

[0140] The operation of the wireless communication system 10 will be described. Specifically, the operation of reacquiring the location information of the UE 200 and the operation of updating the location information of the UE 200 based on the assistance information will be described.

[0141] (3.1)Topic

[0142] (3.1.1) Topic 1

[0143] In the connection state of the radio resource control layer which is a prerequisite for UL transmission, there is a problem of how to receive a radio signal from a satellite positioning system and update the location information of the UE.

[0144] (3.1.2) Topic 2

[0145] When the UE is in the connection state of the radio resource control layer, which is a prerequisite for UL transmission, it is necessary to receive a radio signal from the satellite positioning system and update the UE's location information. In this case, it is necessary to temporarily interrupt the UL transmission. There is a problem of how to handle the segmentation of the interrupted UL transmission.

[0146] (3.1.3) Topic 3

[0147] There is a problem that the power consumption of the UE increases due to receiving a wireless signal from a satellite positioning system and updating the location information of the UE.

[0148] (3.2) Action example

[0149] (3.2.1) Action Example 1

[0150] The control signal and reference signal processing unit 240 sets the MG in the connection state of the radio resource control layer. In the MG, the radio signal transceiver unit 210 receives a radio signal from the satellite positioning system S. The control signal and reference signal processing unit 240 updates the location information of the UE 200 based on the radio signal.

[0151] The valid period can be set for the location information of UE200. During the valid period, the wireless signal transceiver unit 210 can perform UL transmission. On the other hand, even if the wireless signal transceiver unit 210 is the valid period of the location information of UE200, it cannot perform UL transmission during the period in which the MG is set. The MG can also be set with an offset in consideration of the scheduling of UL transmission. The MG can also be set based on a request from UE200.

[0152] (3.2.2) Action Example 2

[0153] Here, in the above-mentioned action example 1, when the scheduling of MG and UL transmission overlaps, the segment of the UL transmission may be discarded. That is, the scheduled UL transmission is not performed even after the MG. On the other hand, the scheduled UL transmission may be performed after the MG without discarding the segment of the UL transmission.

[0154] (3.2.3) Action Example 3

[0155] The control signal / reference signal processing unit 240 obtains the location information of UE200 based on the wireless signal received by the wireless signal transceiver unit 210 from the satellite positioning system S. The wireless signal transceiver unit 210 sends the location information of UE200 to the base station 100. The control signal / reference signal processing unit 240 obtains auxiliary information, which is information related to the movement of UE200. The wireless signal transceiver unit 210 sends the auxiliary information to the base station 100. The base station 100 updates the location information of UE200 based on the auxiliary information, and sends the updated location information of UE200 to UE200.

[0156] The auxiliary information may include at least one of the moving speed of UE 200, the change in the moving speed of UE 200, the derivative of the change in the moving speed of UE 200, and the moving trajectory of UE 200. In addition, the auxiliary information may be the value itself obtained by the control signal / reference signal processing unit 240, or a predicted value calculated based on the value obtained by the control signal / reference signal processing unit 240. In addition, the auxiliary information may be newly obtained based on the validity period of the auxiliary information.

[0157] (3.2.4) Action Example 4

[0158] Here, in the above-mentioned operation example 3, the wireless signal transceiver unit 210 may not send the auxiliary information to the base station 100. In this case, the control signal / reference signal processing unit 240 updates the location information of the UE 200 based on the auxiliary information. In addition, the updated location information of the UE 200 may also be sent to the base station 100 through the wireless signal transceiver unit 210.

[0159] (4) Action and Effect

[0160] The UE 200 of the above-described embodiment can set the MG for receiving a wireless signal from the satellite positioning system in the connection state of the radio resource control layer, which is a prerequisite for UL transmission. Thus, the location information of the UE 200 can be updated in the connection state of the radio resource control layer.

[0161] In addition, if Fig.11As shown, in 3GPP version 17, it is stipulated that a transmission gap is set between segments of UL transmission. On the other hand, when the time involved in the UL transmission of the UE becomes longer, such as in IoT-NTN, the period of the transmission gap is not sufficient. Therefore, in the UE200 of the embodiment, the MG is newly set. As a result, even when the time involved in the UL transmission of the UE becomes longer, the wireless signal can be received from the satellite positioning system S in the MG, so that the location information of the UE200 can be updated.

[0162] Furthermore, the UE 200 of the above-described embodiment can set the MG in an offset manner, thereby allowing for consideration of scheduling of UL transmission.

[0163] Furthermore, the UE 200 of the above-described embodiment can request the base station 100 to set or instruct the MG. Thus, the UE 200 side can set or instruct the MG.

[0164] In addition, when the segments transmitted by the MG and UL overlap, the UE 200 of the above-mentioned embodiment assumes that the segments are overlapped as a whole and does not transmit the segments. In addition, when the segments transmitted by the MG and UL overlap, the UE 200 of the above-mentioned embodiment does not transmit the overlapping portion of the segments or postpones the transmission of the overlapping portion of the segments. In this way, the processing of the segments transmitted by the UL that overlap with the MG can be flexibly handled.

[0165] The UE 200 of the above-described embodiment can update the location information of the UE 200 based on the auxiliary information which is information related to the movement of the UE 200. Thus, since a wireless signal is not received from the satellite positioning system S to update the location information of the UE 200, the power consumption of the UE 200 can be suppressed.

[0166] In addition, the auxiliary information of the above-mentioned embodiment can include at least one of the moving speed of UE 200, the change amount of the moving speed of UE 200, the derivative of the change amount of the moving speed of UE 200, and the moving trajectory of UE 200. Thus, the location information of UE 200 can be updated with high accuracy.

[0167] In addition, the auxiliary information in the above-mentioned embodiment may be a predicted value in a period including the acquisition time. Thus, for example, when the movement of the UE 200 can be expressed as a function, the location information of the UE 200 can be updated with high accuracy.

[0168] Furthermore, the auxiliary information of the above-mentioned embodiment may be newly acquired based on the validity period of the auxiliary information. Thus, the location information of the UE 200 is frequently updated, thereby improving the accuracy of UL transmission.

[0169] Furthermore, the UE 200 according to the above-described embodiment can update the location information of the UE 200 even when the auxiliary information is not transmitted to the base station 100. Thus, the power consumption associated with the transmission of the auxiliary information can be suppressed.

[0170] Furthermore, the UE 200 of the above-described embodiment can transmit the updated location information of the UE 200 to the base station 100. Therefore, even without transmitting the auxiliary information to the base station 100, the updated location information of the UE 200 can be shared with the base station 100.

[0174] In the above disclosure, it is assumed that when a part of the segments transmitted by MG and UL overlap, a part of the segments is postponed, but the present invention is not limited to this. For example, when all the segments transmitted by MG and UL overlap, all the segments may be postponed.

[0175] The above-mentioned operation examples may be combined and applied in a complex manner unless there is any contradiction. For example, even when the MG is set by combining operation examples 1 or 2 with operation examples 3 or 4, the location information of the UE 200 may be updated based on the auxiliary information.

[0190] The input device 1005 is an input device that receives input from the outside (e.g., 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 (e.g., a display, a speaker, an LED light, etc.). In addition, the input device 1005 and the output device 1006 may also be integrally formed (e.g., a touch panel).

[0191] In addition, each device such as the processor 1001 and the memory 1002 is connected via a bus 1007 for communicating information. The bus 1007 may be configured by a single bus or may be configured by different buses between devices.

[0193] In addition, the notification of information is not limited to the form / implementation method described in the present disclosure, and other methods may also be used. For example, the notification of information may be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information: DCI), uplink control information (Uplink Control Information: UCI), high-level signaling (e.g., RRC signaling, medium access control (Medium Access Control: MAC) signaling, broadcast information (Master Information Block: MIB, System Information Block: SIB)), other signals or a combination thereof. In addition, RRC signaling may also be referred to as an RRC message, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

[0196] In the present disclosure, specific actions performed by a base station are sometimes also performed by its upper node according to the situation. In a network composed of one or more network nodes having a base station, various actions performed to communicate with a terminal can be performed by at least one of the base station and other network nodes other than the base station (for example, MME or S-GW, etc., but not limited to these). In the above, the case where there is one other network node other than the base station is illustrated, but it can also be a combination of multiple other network nodes (for example, MME and S-GW).

The input or output information can be rewritten, updated, or appended. The output information can also be deleted. The input information can also be sent to other devices.

[0199] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value (Boolean: true or false), or by comparison of numerical values ​​(for example, comparison with a predetermined value).

[0200] Each form / implementation described in the present disclosure may be used alone or in combination, and may be switched depending on the execution. In addition, notification of scheduled information is not limited to being performed explicitly (e.g., notification of "yes X"), but may also be performed implicitly (e.g., notification of the scheduled information is not performed).

[0204] In addition, the terms described in the present disclosure and the terms required for understanding the present disclosure may also be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol may also be a signal (signaling). In addition, a signal may also be a message. In addition, a component carrier (CC) may also be referred to as a carrier frequency, a cell, a frequency carrier, etc.

[0205] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0206] In addition, the information, parameters, etc. described in the present disclosure may be represented by absolute values, relative values ​​to predetermined values, or other corresponding information. For example, wireless resources may also be indicated by indexes.

[0207] The names used for the above parameters are non-restrictive names in any respect. Furthermore, the formulas etc. using these parameters may sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements may be identified by any appropriate names, and therefore the various names assigned to these various channels and information elements are non-restrictive names in any respect.

[0208] In the present disclosure, the terms "base station (BS)", "wireless base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", "component carrier" and the like are used interchangeably. Sometimes, the base station is also referred to as macro cell, small cell, femto cell, pico cell and the like.

[0209] A base station can accommodate one or more (e.g., 3) cells (also called sectors). When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, each of which can also provide communication services through a base station subsystem (e.g., a small base station for indoor use (Remote Radio Head: RRH)).

[0210] The terms "cell" or "sector" refer to a part or the entirety of a coverage area of ​​at least one of a base station and a base station subsystem that provide communication services within the coverage area.

[0211] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” may be used interchangeably.

[0212] For mobile stations, those skilled in the art sometimes also use the following terms: 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 appropriate terms.

[0213] At least one of the base station and the mobile station may also be referred to as a transmitting device, a receiving device, a communication device, etc. In addition, at least one of the base station and the mobile station may also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body may be a means of transportation (e.g., a car, an airplane, etc.), a mobile body that moves in an unmanned manner (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0214] In addition, the base station in the present disclosure may also be replaced by a mobile station (user terminal, the same below). For example, various forms / implementations of the present disclosure may also be applied to a structure in which the communication between a base station and a mobile station is replaced by communication between multiple mobile stations (for example, it may also be referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, it may also be configured such that the mobile station has the functions of the base station. In addition, terms such as "uplink" and "downlink" may also be replaced by terms corresponding to communication between terminals (for example, "side"). For example, uplink channels, downlink channels, etc. may also be replaced by side channels.

[0215] Likewise, the mobile station in the present disclosure may be replaced by a base station. In this case, the base station may have the same functions as the mobile station.

[0216] A radio frame may be composed of one or more frames in the time domain. In the time domain, one or more frames may be referred to as subframes.

[0217] A subframe may also be composed of one or more time slots in the time domain. A subframe may be of a fixed time length (eg, 1 ms) that is independent of a numerology.

[0218] A parameter set may be a communication parameter applied to at least one of the transmission and reception of a certain signal or channel. The parameter set may, for example, represent at least one of a subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), the number of symbols per TTI, a wireless frame structure, a specific filtering process performed by a transceiver in the frequency domain, a specific windowing process performed by a transceiver in the time domain, and the like.

[0219] A time slot can be composed of one or more symbols in the time domain (OFDM (Orthogonal Frequency Division Multiplexing: Orthogonal Frequency Division Multiplexing) symbol, SC-FDMA (Single Carrier Frequency Division Multiple Access: Single Carrier Frequency Division Multiple Access) symbol, etc. ) A time slot may be a time unit based on a parameter set.

[0220] A time slot may contain multiple mini-slots. Each mini-slot may be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may be composed of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in units of time greater than a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type B.

[0221] A radio frame, a subframe, a time slot, a mini-time slot, and a symbol all represent time units for transmitting signals. A radio frame, a subframe, a time slot, a mini-time slot, and a symbol may be referred to by other corresponding names.

[0222] For example, one subframe may be referred to as a transmission time interval (TTI), multiple consecutive subframes may be referred to as a TTI, and one time slot or one mini time slot may be referred to as a TTI. That is, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. In addition, the unit representing a TTI may be referred to as a time slot, a mini time slot, or the like instead of a subframe.

[0223] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station schedules the allocation of wireless resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) to each user terminal in units of TTI. In addition, the definition of TTI is not limited to this.

[0224] TTI can be a transmission time unit of data packets (transport blocks), code blocks, code words, etc. after channel coding, or a processing unit such as scheduling and link adaptation. In addition, when TTI is given, the time interval (e.g., the number of symbols) to which the transport block, code block, code word, etc. is actually mapped can also be shorter than the TTI.

[0225] In addition, when one time slot or one mini time slot is called TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) may also be the minimum time unit for scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit for scheduling may also be controlled.

[0226] A TTI with a time length of 1 ms is also 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 time slot, etc. A TTI shorter than a normal TTI may also be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini-time slot, a sub-time slot, a time slot, etc.

[0227] In addition, for a long TTI (for example, a normal TTI, a subframe, etc.), it can be understood as a TTI with a time length exceeding 1ms, and for a short TTI (for example, a shortened TTI, etc.), it can be understood as a TTI with a TTI length less than that of a long TTI (long TTI) and greater than 1ms.

[0228] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain. In the frequency domain, it may include one or more consecutive subcarriers. The number of subcarriers included in an RB may be the same regardless of the parameter set, for example, it may be 12. The number of subcarriers included in an RB may also be determined according to the parameter set.

[0229] In addition, the time domain of an RB may include one or more symbols, and may be the length of one slot, one mini slot, one subframe, or one TTI. One TTI, one subframe, etc. may be composed of one or more resource blocks, respectively.

[0230] In addition, one or more RBs may also be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, and the like.

[0231] In addition, a resource block may be composed of one or more resource elements (RE). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0232] A Bandwidth Part (BWP) (also referred to as a partial bandwidth, etc.) represents a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, a common RB can be identified by the index of the RB relative to the common reference point of the carrier. PRBs can be defined in a BWP and numbered within the BWP.

[0233] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0234] At least one of the set BWPs may be active, and it is not assumed that the UE transmits or receives a predetermined signal / channel outside the activated BWP. In addition, "cell", "carrier" and the like in the present disclosure may be replaced with "BWP".

[0235] The above structures of radio frames, subframes, time slots, mini-time slots, and symbols are merely examples. For example, the number of subframes included in a radio frame, the number of time slots per subframe or radio frame, the number of mini-time slots included in a time slot, the number of symbols and RBs included in a time slot or mini-time slot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, and the like may be changed in various ways.

[0236] The terms "connected", "coupled" or all variations of these terms are intended to indicate any direct or indirect connection or combination between two or more elements, and may include the presence of one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be a physical combination or connection, a logical combination or connection, or a combination of these. For example, "access" may be used instead of "connection". In the context of the present disclosure, two elements may be considered to be "connected" or "coupled" to each other using at least one of one or more wires, cables, and printed electrical connections, and as some non-limiting and non-inclusive examples, electromagnetic energy having wavelengths in the wireless frequency domain, microwave region, and light (including both visible and invisible) region may be used to "connect" or "couple" to each other.

[0237] The reference signal may be referred to as Reference Signal (RS) for short, or may be referred to as a pilot signal depending on the applicable standard.

[0238] The phrase "according to" used in the present disclosure does not mean "only according to" unless otherwise expressly stated. In other words, the phrase "according to" means both "only according to" and "at least according to".

[0239] The “unit” in the configuration of each of the above-mentioned devices may be replaced with a “section”, “circuit”, “device” or the like.

[0240] Any reference to an element using the designations "first," "second," etc. used in this disclosure does not necessarily limit the number or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, reference to the first and second elements does not mean that only two elements can be used there, or that the first element must precede the second element in some form.

[0241] When the terms "include", "including" and their variations are used in the present disclosure, these terms are intended to be inclusive like the term "comprising". Furthermore, the term "or" used in the present disclosure does not mean an exclusive or.

[0242] In the present disclosure, when an article is added by translation, such as a, an, and the in English, the present disclosure also includes a case where the noun following the article is in a plural form.

[0243] The terms "determining" and "determining" used in the present disclosure sometimes also include a variety of actions. "Determining" and "determining" may include, for example, considering matters that have been judged, calculated, calculated, processed, derived, investigated, searched (for example, searched in a table, database or other data structure), confirmed (ascertaining) as matters that have been "determined" or "determined", etc. In addition, "determining" and "determining" may include matters that have been received (for example, receiving information), transmitted (for example, transmitting information), input, output, accessed (for example, accessing data in a memory) as matters that have been "determined" or "determined", etc. In addition, "determining" and "determining" may include matters that have been resolved (resolving), selected (selecting), chosen (choosing), established (establishing), compared (comparing), etc. as matters that have been "determined" or "determined". That is, "judgment" and "decision" may include certain actions that are considered to be "judged" or "decided". In addition, "judgment (decision)" may also be replaced by "assuming", "expecting", "considering", etc.

[0244] In the present disclosure, the term "A and B are different" may mean "A and B are different from each other". In addition, the term may mean "A and B are different from C, respectively". The terms "separate" and "combined" may also be interpreted in the same way as "different".
