Description

The present invention relates to the field of wireless communication, and specifically relates to a method and an apparatus for wireless communication using a new frame structure.

Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, message transmission and broadcasting services. These wireless communication networks may be multiple access networks that share available network resources and support multiple users. Examples of such multiple access networks include code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, and single carrier FDMA (SC-). FDMA) network included.

図１はＬＴＥ ＴＤＤシステムの無線フレーム構造を示す図であり、ここで、特別サブフレームは下りパイロットタイムスロット（ＤｗＰＴＳ）を含み、下りから上りへの切替の保護時間（ＧP）及び上りパイロットタイムスロット（ＵｐＰＴＳ）に用いられる。 In the fifth generation (5G) mobile communication system under consideration, the high frequency band (carrier frequency is 6 GHz-100 GHz) is an important placement scene. For high frequency bands, Time Division Duplex (TDD), which employs the same frequency bands for uplink and downlink, is a more appropriate duplex mode. Currently, the long-term evolution (LTE) TDD system has seven TDD configurations, with each subframe (subframe) having a continuous time of 1 ms and D indicating the downlink subframe, as shown in Table 1. U indicates an upstream subframe and S indicates a special subframe.

FIG. 1 shows the radio frame structure of an LTE TDD system, where the special subframe includes a downlink pilot time slot (DwPTS), a downlink-to-uplink protection time (GP), and an uplink pilot time slot. (UpPTS).

Since the 5G system is mainly arranged in the high frequency band, the coverage range by the cells of the 5G system is significantly smaller than that of the 4G and 3G systems. The smaller the cell range, the smaller the number of users in each cell, and the data traffic in such cells can be faster with changes in service. In order to adapt to fast changes in cell data traffic, the 5G system may adopt a configuration scheme similar to the LTE TDD system, i.e., by switching among the seven TDD configurations, for uplink / downlink data traffic. Changes can be applied. However, current LTE TDD system configurations may not meet the demands of fast-moving changes in the data traffic of 5G systems.

Also, unlike conventional mobile communication systems such as LTE systems, which are mainly mobile broadband (MBB), 5G systems support services with a wide variety of needs, and they are enhanced mobile broadband (MBB). eMBB), including at least reliable low-latency communication (URLLC) and large-scale (low-cost) machine-type communication (mMTC). 5G systems can support different services because these services have different requirements for key indicators such as rate, delay, transmission reliability and power consumption / energy efficiency (waveform), which in turn have large differences. You need enough flexibility to be able to.

Also, since the frequency bandwidth of a 5G system is wide and the bandwidth of one carrier wave can reach 100 MHz or more, when the 5G system uses the same uplink / downlink ratio configuration for the entire carrier wave as in LTE TDD. , Can cause great constraints and waste. Conversely, as in the TDD configuration of FIG. 1a, the same when adjacent TDD carriers within the same TDD carrier wave or on the frequency domain in the same geographic area or adjacent geographic areas use different uplink / downlink ratios. The uplink and downlink subframes indicated by the subframe numbers cause strong uplink / downlink interference over the entire carrier bandwidth, reducing system capacity and thus rendering carriers in some areas unusable. ..

Therefore, 5G systems efficiently support various uplink / downlink ratios between adjacent carriers within the same carrier and in the frequency domain, flexibly adapting to fast changes in cell data traffic, and related interference issues. Need to be resolved or reduced.

The embodiments of the present invention can flexibly adapt changes in uplink / downlink data traffic of a wireless communication system, support radio indicators required by a wide variety of different services, and solve or reduce corresponding interference problems. Provide methods and devices for wireless communication capable.

In all figures, the same reference numerals indicate similar or corresponding features or functions.

The above and other features and advantages of the present invention will be clarified with reference to the above figure.

FIG. 2 is a diagram showing a resource configuration according to one embodiment of the present invention. In the frame structure shown in FIG. 2, radio resources are classified as a plurality of resource units in terms of time and frequency, and are shown by the time length and the frequency bandwidth occupied by each resource unit (hereinafter, referred to as time span and frequency span). For convenience of explanation, the plurality of resource units shown in the example have a total length in time as one frame length, for example, 10 ms, but are not limited to, and the total length in frequency is one carrier wave of the cell. The frequency bandwidth is, for example, 100 MHz, but the frequency bandwidth is not limited to this.

In the frame structure shown in FIG. 2, radio resources are allocated in units of time-frequency resource units, and the time span and frequency span occupied by each resource unit are not always the same, and may or may be configured in the same manner. May be configured in, thereby providing a flexible resource configuration. By flexibly configuring the time span and frequency span of each resource unit, it is possible to support different needs of different upstream / downstream ratios and different services. For example, as shown in the first column, third row and fifth row of FIG. 2, by providing an uplink / downlink resource unit with a larger time span, the performance of a sudden service can be improved. In particular, it is advantageous for a large sudden service transmission scene.

Each resource unit is referred to as a resource unit for uplink transmission (hereinafter referred to as an uplink resource unit as shown by the up arrow in the figure) and a resource unit for downlink transmission (hereinafter referred to as a downlink as indicated by the down arrow in the figure). It can be configured as a resource unit (referred to as a resource unit) or a resource unit for protection (hereinafter referred to as a protection resource unit as shown by a gray frame in the figure).

Protected resource units are used to isolate two resource units that may interfere with each other in the frequency domain. As shown in FIG. 2, when two overlapping resource units in the time domain may interfere with each other, one protection resource unit can be arranged between the two resource units. In addition, here, overlapping includes partially overlapping and completely overlapping. The two resource units before and after overlapping in the time domain are the two resource units before and after in the frequency.

In one embodiment, when the transmission direction changes between the resource units before and after overlapping in the time domain, for example, when one is an uplink resource unit and the other is a downlink resource unit, these two resources. Protected resource units can be placed between the units.

In another embodiment, when the transmission directions of the two resource units before and after overlapping in the time domain are the same, for example, when both are downlink resource units or both are uplink resource units, the related parameters of these two resource units are used. It is possible to determine whether or not a protected resource unit needs to be placed between the two resource units based on. Generally, if the related parameters of these two resource units are different, a protected resource unit can be placed between them. For example, the related parameters of one resource unit are time span, frequency span, subcarrier spacing, number of subcarriers, cyclic prefix (CP) length, presence / absence of downlink measurement reference signal (RS), and configuration information of downlink measurement RS. , Whether to support transmission of uplink detection signal (SRS), SRS configuration information, whether to support transmission of physical uplink control channel (PUCCH), PUCCH configuration information, physical downlink control channel (PDCCH) or Includes at least one of the PDCCH / EPDCCH configuration information, whether to support transmission of the augmented physical downlink control channel (EPDCCH). For example, when the subcarrier spacing of the two resource units is different, the protection resource unit can be arranged between the two resource units. For example, if one resource unit contains one or more 15 kHz subcarriers, while another resource unit contains one or more 7.5 kHz subcarriers, the subcarrier spacing is different and therefore the subcarriers. There is a problem that they are not orthogonal, which causes a large interference between the two resource units, and a protection resource unit can be provided between them.

In other embodiments, when deciding whether to place a protected resource unit, such a factor as to whether or not the two resource units before and after overlapping in the time domain satisfy the protection condition of mutual interference in the frequency domain. Is also possible, for example, in the case of whether or not the external radiation of the resource unit is larger than a certain threshold value, and if the external radiation is larger than the threshold value, the protection resource unit is inserted.

In other embodiments, when deciding whether or not to arrange the protection resource unit, it is possible to consider other factors other than the above two embodiments. For example, if the transmission direction between the two resource units before and after overlapping in the time domain is changed and the protection condition for mutual interference is not satisfied in the frequency domain, the protection resource unit is arranged between the two resource units. Can be done. For example, if the related parameters of the two resource units before and after overlapping in the time domain are different and the protection conditions for mutual interference are not satisfied in the frequency domain, the protection resource unit can be arranged between them.

In one embodiment, when arranging a protected resource unit between two resource units before and after overlapping in the time domain, the protected resource unit covers the overlapping portion in time of the two resource units to be protected. Arranged to do.

In one embodiment, when a protected resource unit is arranged between two resource units before and after overlapping in the time domain, the frequency span of the protected resource unit is determined based on the characteristics of the two protected resource units. Can be done. For example, usually one of these two resource units is the interfering side and the other is the interfering side, and of course, they may interfere with each other, and the downlink transmission is typically the uplink reception. have a finger in the pie. Interference side characteristics (eg parameters such as basic signal waveform and subcarrier width, transmission power, size of resources used continuously in the frequency domain, etc.) and necessary degree or performance requirement to be protected on the interference receiving side (for example, basics to be used) The frequency span of the protection resource unit can be determined based on the signal waveform and parameters, the maximum possible interference characteristics of the service type, etc., such as blocking and desensitization). In other embodiments, the frequency span of the protection resource unit may be predefined.

In one embodiment, the time span and / or frequency span of the protection resource unit may be indicated by signaling. For example, the base station instructs the terminal. In other embodiments, the resource allocation status can imply the frequency span of the protected resource unit, so that the base station explicitly indicates the frequency span and / or time span of the protected resource unit to the terminal. It is not necessary to instruct the terminal only the time frequency information of the uplink resource unit and the downlink resource unit, and the time frequency information of the protection resource unit can be determined. Correspondingly, the base station does not need to clearly instruct the terminal of the type information of the protected resource unit, and the type information indicates that a resource unit is a protected resource unit.

In one embodiment, no information needs to be transmitted in the time-frequency domain of the protected resource unit, i.e., the protected resource unit is placed as a blank resource unit.

In another embodiment, information for reducing out-of-band radiation of the uplink / downlink resource unit may be transmitted in the time-frequency domain of the protection resource unit, for example, the bandwidth of the uplink / downlink resource unit in the protection resource unit. Information opposite to the phase of the external radiation can be transmitted to further reduce the interference of the uplink / downlink resource units.

The resource configuration method in one embodiment has been described above with reference to the frame structure shown in FIG. It should be noted that, based on a method similar to the frame structure shown in FIG. 2, a plurality of specific resource configuration methods are provided, an appropriate resource configuration method is used according to the network status, or resources are used according to the network status. The configuration method can be adjusted dynamically.

In the description of FIG. 2, the resource configuration method in one embodiment is described by taking one carrier wave of the cell as an example. The cell may have a plurality of carriers, for example, but is not limited to three carriers. The resource configuration method shown in FIG. 2 can also be applied to a plurality of carrier waves. For example, in the case of a plurality of carrier aggregations of a cell, the total bandwidth after aggregation is divided by frequency to acquire a plurality of resource units, and the total bandwidth in the frequency direction of FIG. 2 at this time is the total bandwidth after carrier aggregation. May be perceived as the total bandwidth of. Further, for example, the resource configuration of the frame structure shown in FIG. 2 may be provided for each of the plurality of carrier waves of the cell, and the resource configurations provided for each of the plurality of carrier waves may be the same or different. You should understand that it is okay.

In the above, the total bandwidth of the frequency domain of the frame structure shown in FIG. 2 is described as the bandwidth of the target carrier wave, but the frequency domain bandwidth which is the basis of the division is a part of the total bandwidth of the target carrier wave. There may be.

As described above, in the frame structure shown in FIG. 2, each resource unit divided by frequency and time is shown to be continuous in frequency in FIG. 2, but the resource units divided by frequency are continuous in frequency. It should be understood that they may be adjacent rather than adjacent. For example, there may be a certain distance in frequency between the two resource units before and after they overlap at the time of division. Further, for example, between two resource units that overlap in time, one resource unit generates non-negligible radiation in a certain frequency range outside the resource unit, for example, radiation exceeding a threshold value is generated, and the other resource unit. Part or all of is within the range of radiation above the threshold, in which case the two resource units may be received as adjacent.

FIG. 3 is a flowchart of the communication method 300 according to one embodiment of the present invention.

In step S310, the base station determines the resource configuration information, and the resource configuration information indicates, for example, the resource configuration or frame structure shown in FIG. 2 above. Specifically, the resource configuration information is used to determine a plurality of resource units divided by the frequency and time of a specific carrier wave and the type information of each resource unit. For example, the type information of each resource unit indicates that the resource unit is one of an uplink resource unit, a downlink resource unit, and a protection resource unit.

In one embodiment, the resource configuration information clearly indicates the size, location and type of a plurality of resource units, separated by frequency and time. In other embodiments, the resource configuration information clearly indicates the size, location, and type of uplink and downlink resource units within a plurality of resource units separated by frequency and time. The terminal can determine the size and position of the protection resource unit based on the size and position of the uplink resource unit and the downlink resource unit. In this case, the resource configuration information implies the size, location and type of the protected resource unit.

In one embodiment, the base station can select one resource configuration from a variety of predefined resource configurations. In another embodiment, the base station can dynamically generate the above resource configuration information. In other embodiments, the base station can dynamically adjust the configuration of at least some resource units on top of a predefined resource configuration.

In step S320, the base station transmits the finalized resource configuration information. In one embodiment, the resource configuration information may be transmitted by system information (SI). In other embodiments, the resource configuration information may be transmitted by higher layer signaling. In another embodiment, the resource configuration information may be transmitted by downlink control information (DCI).

In step S330, after receiving the resource configuration information, the terminal can determine the resource configuration of the cell, for example, the resource configuration shown in FIG. 2, based on the configuration information.

In step S340, communication can be realized between the terminal and the base station at a frequency of a specific carrier wave based on the resource configuration shown.

In one embodiment, in step S320, the base station repeatedly transmits the resource configuration information to be used, based on the resource configuration used by the resource configuration information (eg, the type of each resource unit and / or related parameters). The frame length is periodically repeated, for example, in units of the frame length, and the frame length is, for example, 10 ms, but is not limited thereto. For example, the resource configuration information is periodically transmitted by system information or upper layer signaling.

In another embodiment, in step S310, the base station updates the resource configuration information according to the network condition (for example, the performance requirement of the current service), and in step S320, transmits the updated resource configuration information. .. For example, DCI transmits the updated resource configuration information. For example, in a common search space (CSS), a DCI containing the configuration information is transmitted. In one embodiment, the base station does not need to wait for the end of one frame and then transmit the updated resource configuration information, but transmits the updated resource configuration information at any time within the frame. It may be possible to quickly adapt to changing communication performance requirements.

FIG. 4 is a flowchart of the communication method 400 according to one embodiment of the present invention.

In step S410, the base station determines the resource configuration information and is similar to the operation in step S310.

In step S420, the base station repeatedly transmits the resource configuration information to be used. It repeats periodically based on the resource configuration used by the resource configuration information (for example, the type of each resource unit and / or related parameters), for example, it repeats periodically in units of frame length. For example, the resource configuration information is periodically transmitted by system information or upper layer signaling.

In step S430, after receiving the resource configuration information, the terminal can determine the resource configuration on the specific carrier wave based on the configuration information.

In step S440, the terminal and the base station can realize communication on a specific carrier wave based on the periodically repeated resource configuration.

In step S450, the base station dynamically adjusts a part or the whole of the resource configuration (for example, the type and / or related parameters of the part or the whole resource unit) to acquire the updated resource configuration. Moreover, the base station can determine the expiration date of the updated resource configuration. For example, a base station determines the expiration date of an updated resource configuration as temporarily valid, for example, maintains one or more transmission time intervals, and then automatically recovers to the previous cyclically repeating resource configuration. To do. For example, a base station can determine that an updated resource configuration remains in effect until it receives the next updated resource configuration. In this case, the periodic resource configuration transmitted in step S410 should be the currently valid resource configuration.

In step S460, the base station transmits the updated resource configuration, and selects and transmits an instruction that the updated resource configuration is temporarily valid. For example, DCI transmits the updated resource configuration information. Correspondingly, after receiving the updated resource configuration, the terminal determines that the updated resource configuration is valid at the temporary expiration date, and then the base cyclically repeating resource. It ensures that the updated resource configuration remains valid until it recovers to the configuration or receives the next updated resource configuration. For example, when based on a cyclically repeating resource configuration, the terminal manipulates according to dynamically changing resource configuration information after a specific point in time and recovers to the underlying cyclically repeating resource configuration. It does not have to be. The specific time point is, for example, a preset time point, a time point specified by the base station, or a time point corresponding to an instruction from the base station, and the instruction from the base station is, for example, the following updated resource configuration. Indicates that the updated resource configuration remains valid until it receives.

In step S470, the terminal and the base station communicate on the target carrier wave based on the updated resource configuration, and optionally, after the validity period of the updated resource configuration, the recovered resource. Realize communication based on the configuration.

FIG. 5 is a flowchart of a communication method according to an embodiment of the present invention.

In step S510, the base station allocates resources to terminals and generates resource scheduling information. The resource scheduling information indicates a resource unit for terminals in a plurality of resource units having the above resource configuration to receive or transmit data.

Here, for example, the flexible resource configuration method shown in FIG. 2 is used, and the confirmation feedback mechanism is further improved.

In one embodiment, the base station allocates or schedules resource unit A for downlink data transmission to the terminal and receives the corresponding ACK / NACK after the N1 transmission interval (TTI) after the resource unit. Schedule to do so. This means that after the N1 transmission interval (TTI), one uplink resource unit B needs to be scheduled to confirm the feedback. The range of values of N1 may differ for different types of terminals (eg, eMBB, URLLC and mMTC). In one embodiment, the time position of the uplink resource unit B can be determined based on the time position and time offset of the downlink resource unit A, where the time offset is the unit time span and N1. Equal to the product. In one embodiment, the unit time span is equal to the time span of the downlink resource unit A. In other embodiments, the unit time span is implicitly determined based on the time span of the downlink resource unit A. For example, the unit time span can be calculated based on the time span of the downlink resource unit A based on a predefined calculation method. In other embodiments, the unit time span can be determined by signaling from the base station.

In another embodiment, the base station allocates or schedules a resource unit C for uplink data transmission to the terminal and receives the corresponding ACK / NACK after the N2 transmission interval (TTI) after the resource unit. Schedule as. This means that after N2 transmission intervals (TTIs), one downlink resource unit D needs to be scheduled to confirm feedback. The range of values of N2 may differ for different types of terminals (eg, eMBB, URLLC and mMTC). In one embodiment, the time position of the resource unit D is determined based on the time position and the time offset of the resource unit C, where the time offset is equal to the product of the unit time span and N2. In one embodiment, the unit time span is equal to the time span of the uplink resource unit C. In other embodiments, the unit time span can be implicitly determined based on the time span of the uplink resource unit C. In other embodiments, the unit time span can be determined by signaling from the base station.

In one embodiment, the transmission interval (TTI) value may be the scheduled time span of the resource unit for data transmission. The time span of the resource unit for data transmission, which is scheduled, does not change.

In other embodiments, the base station may determine that ACK feedback is not required. For example, a value of N1 or N2 can be set as a particular value, for example 0, to indicate that no ACK feedback is needed.

In step S510, the base station schedules a resource unit for transmitting or receiving confirmation feedback corresponding to the data, in addition to scheduling a resource unit for receiving or transmitting data for the terminal. The base station may explicitly indicate the resource unit for feedback in the resource allocation message, or may indicate the above N1 or N2 in the resource allocation message so as to imply the resource unit for the feedback. Good.

In step S520, the base station transmits the generated resource scheduling information. For example, the resource scheduling information may be transmitted by DCI.

In step S530, the terminal uses the resource scheduling information to determine the transmission resource to be allocated to the terminal.

In step S540 or step S540', the terminal receives the downlink data or transmits the uplink data by using the resource unit to be allocated shown in the resource scheduling information.

In step S550 or step S550', the terminal transmits confirmation information for downlink data or confirms information for uplink data in the resource for transmitting confirmation information shown in the resource scheduling information. Receive.
