[0002] In order to meet the increased demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or quasi-5G communication systems. Therefore, 5G or quasi-5G communication systems are also referred to as "super 4G networks" or "post-LTE systems."

[0003] 5G communication systems are implemented in higher frequency (millimeter wave, mmWave) bands, such as the 60GHz band, to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technology are discussed in 5G communication systems.

[0004] In addition, in the 5G communication system, development of system network improvements is underway based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, collaborative communications, coordinated multi-point (CoMP), receiving-end interference cancellation, etc.

[0005] In the 5G system, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as advanced coding modulation (ACM), filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA), and smart metasurface (RIS, Reconfigurable Intelligent Surface) as advanced access technologies have been developed.

[0048] Figure 1 An example wireless network 100 is shown in accordance with various embodiments of the present disclosure. Figure 1 The embodiment of the wireless network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.

[0049] Wireless network 100 includes gNodeB (gNB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data network.

[0050] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, other well-known terms such as "mobile station", "subscriber station", "remote terminal", "wireless terminal" or "user device" can be used instead of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to a remote wireless device that wirelessly accesses a gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or a generally determined fixed device (such as a desktop computer or vending machine).

[0051] gNB 102 provides wireless broadband access to network 130 for a first plurality of user equipment (UE) within coverage area 120 of gNB 102. The first plurality of UEs include: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); UE 116, which may be a mobile device (M), such as a cellular phone, a wireless laptop, a wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within coverage area 125 of gNB 103. The second plurality of UEs include UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 may be capable of communicating with each other and with UEs 111-116 using 5G, long term evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.

[0052] The dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0053] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and structure for a system with a 2D antenna array.

[0054] although Figure 1 One example of a wireless network 100 is shown, but Figure 1 Various changes may be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Also, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0055] Figure 2a and Figure 2b Example wireless transmit and receive paths according to the present disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102) and receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system with a 2D antenna array as described in embodiments of the present disclosure.

[0056] The transmit path 200 includes a channel coding and modulation block 205, a serial to parallel (S to P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel to serial (P to S) block 220, an add cyclic prefix block 225, and an upconverter (UC) 230. The receive path 250 includes a downconverter (DC) 255, a remove cyclic prefix block 260, a serial to parallel (S to P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel to serial (P to S) block 275, and a channel decoding and demodulation block 280.

[0057] In the transmit path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulation symbols. The serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in the gNB 102 and the UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. The parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from the N-point IFFT block 215 to generate a serial time-domain signal. The add cyclic prefix block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the add cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before conversion to RF frequency.

[0058] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through a wireless channel, and an operation opposite to that at gNB 102 is performed at UE 116. Downconverter 255 downconverts the received signal to a baseband frequency, and remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0059] Each of gNBs 101-103 may implement a transmit path 200 similar to that for transmitting in the downlink to UEs 111-116 and may implement a receive path 250 similar to that for receiving in the uplink from UEs 111-116. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting in the uplink to gNBs 101-103 and may implement a receive path 250 for receiving in the downlink from gNBs 101-103.

[0060] Figure 2a and Figure 2b Each of the components in can be implemented using hardware only, or a combination of hardware and software / firmware. As a specific example, Figure 2a and Figure 2bAt least some of the components in can be implemented with software, while other components can be implemented by configurable hardware or a mixture of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as a configurable software algorithm, in which the value of the number of points N can be modified according to the implementation.

[0061] In addition, although described as using FFT and IFFT, this is illustrative only and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer as a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0062] although Figure 2a and Figure 2b An example of a wireless transmit and receive path is shown, but the Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components in can be combined, further subdivided or omitted, and additional components can be added according to specific needs. Figure 2a and Figure 2b It is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

[0063] Figure 3a An example UE 116 according to the present disclosure is shown. Figure 3a The embodiment of UE 116 shown in FIG. 1 is for illustration only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a variety of configurations, and Figure 3a The scope of the present disclosure is not limited to any particular implementation of the UE.

[0064] UE 116 includes antenna 305, radio frequency (RF) transceiver 310, transmit (TX) processing circuit 315, microphone 320, and receive (RX) processing circuit 325. UE 116 also includes speaker 330, processor / controller 340, input / output (I / O) interface 345, input device(s) 350, display 355, and memory 360. Memory 360 includes operating system (OS) 361 and one or more applications 362.

[0065] The RF transceiver 310 receives incoming RF signals from the antenna 305 transmitted by the gNB of the wireless network 100. The RF transceiver 310 downconverts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuit 325, where the RX processing circuit 325 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 325 sends the processed baseband signal to the speaker 330 (such as for voice data) or to the processor / controller 340 (such as for web browsing data) for further processing.

[0066] The TX processing circuit 315 receives analog or digital voice data from the microphone 320, or receives other outgoing baseband data (such as network data, email, or interactive video game data) from the processor / controller 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 305.

[0067] The processor / controller 340 can include one or more processors or other processing devices and execute an OS 361 stored in the memory 360 to control the overall operation of the UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 310, the RX processing circuit 325, and the TX processing circuit 315 according to well-known principles. In some embodiments, the processor / controller 340 includes at least one microprocessor or microcontroller.

[0068] The processor / controller 340 is also capable of executing other processes and programs resident in the memory 360, such as operations for channel quality measurement and reporting for a system with a 2D antenna array as described in the embodiments of the present disclosure. The processor / controller 340 is capable of moving data into or out of the memory 360 as needed for the executed process. In some embodiments, the processor / controller 340 is configured to execute applications 362 based on the OS 361 or in response to signals received from the gNB or operator. The processor / controller 340 is also coupled to the I / O interface 345, where the I / O interface 345 provides the UE 116 with the ability to connect to other devices such as laptops and handheld computers. The I / O interface 345 is the communication path between these accessories and the processor / controller 340.

[0069] Processor / controller 340 is also coupled to input device(s) 350 and display 355. An operator of UE 116 can input data into UE 116 using input device(s) 350. Display 355 can be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). Memory 360 is coupled to processor / controller 340. A portion of memory 360 can include random access memory (RAM), while another portion of memory 360 can include flash memory or other read-only memory (ROM).

[0070] although Figure 3a An example of UE 116 is shown, but it is possible to Figure 3a Make various changes. For example, Figure 3a The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, processor / controller 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although Figure 3a The UE 116 is shown configured as a mobile phone or smart phone, but the UE can be configured to operate as other types of mobile or stationary devices.

[0071] Figure 3b An example gNB 102 according to the present disclosure is shown. Figure 3b The embodiment of the gNB 102 shown in FIG. is for illustration only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a variety of configurations, and Figure 3b The scope of the present disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structure as gNB 102.

[0072] like Figure 3b As shown in FIG. 1 , gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0073] The RF transceivers 372a-372n receive incoming RF signals from the antennas 370a-370n, such as signals transmitted by a UE or other gNB. The RF transceivers 372a-372n downconvert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 376 sends the processed baseband signals to the controller / processor 378 for further processing.

[0074] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceivers 372a-372n receive the outgoing processed baseband or IF signals from the TX processing circuit 374 and up-convert the baseband or IF signals to RF signals that are transmitted via the antennas 370a-370n.

[0075] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceivers 372a-372n, the RX processing circuitry 376, and the TX processing circuitry 374 in accordance with well-known principles. The controller / processor 378 can also support additional functionality, such as more advanced wireless communication functionality. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process, such as performed through a Blind Interference Sensing (BIS) algorithm, and decode a received signal with an interference signal subtracted. The controller / processor 378 can support any of a variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0076] The controller / processor 378 can also execute programs and other processes resident in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communications between entities such as web RTC. The controller / processor 378 can move data into or out of the memory 380 as needed by the executing process.

[0077] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The backhaul or network interface 382 can support communication via any suitable (multiple) wired or wireless connections. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0078] The memory 380 is coupled to the controller / processor 378. A portion of the memory 380 can include RAM, while another portion of the memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions such as a BIS algorithm are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0079] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using the RF transceivers 372a-372n, the TX processing circuitry 374, and / or the RX processing circuitry 376) support aggregated communications with FDD cells and TDD cells.

[0080] although Figure 3b An example of a gNB 102 is shown, but the Figure 3b For example, gNB 102 can include any number of Figure 3a . As a specific example, an access point can include a number of backhaul or network interfaces 382, ​​and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, while shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0081] Exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0082] The communication system includes a time division duplex (TDD) and a frequency division duplex (FDD) system. In a TDD system, a base station can configure the uplink and downlink attributes in different time resources on a carrier (the carrier can also be replaced by a service cell) through semi-static signaling and dynamic signaling, for example, uplink transmission time slots / symbols (such as OFDM symbols), downlink transmission time slots / symbols, and flexible time slots / symbols. In an FDD system, a base station can respectively configure different time resources of an uplink carrier in a pair of uplink and downlink carriers as uplink transmission time slots / symbols or flexible time slots / symbols, and different time resources of a downlink carrier as downlink transmission time slots / symbols or flexible time slots / symbols.

[0083] Exemplarily, semi-static signaling may be higher-layer signaling (also known as radio resource control (RRC) signaling). Dynamic signaling may be group-common downlink control information (DCI), which does not schedule physical downlink shared channels (PDSCH) and physical uplink shared channels (PUSCH). Dynamic signaling may also be DCI that schedules physical downlink shared channels (PDSCH) and physical uplink shared channels (PUSCH).

[0084] Compared with the FDD system, the time delay of uplink or downlink transmission in the TDD system is relatively large because the uplink and downlink transmission are time-division multiplexed. For example, according to an uplink and downlink configuration, in a 10ms (millisecond) cycle, only 1ms of the time slot is for uplink transmission, and the other time slots are all downlink transmission or flexible transmission. The maximum delay of uplink transmission is 9ms.

[0085] The present disclosure aims to propose a solution to reduce the transmission delay in a TDD system and to make full use of resources while ensuring data transmission performance.

[0086] In order to reduce transmission delay, the present disclosure proposes to configure part of the frequency domain resources in a carrier for uplink transmission and the other part of the frequency domain resources for downlink transmission.

[0087] In a TDD system, a base station may configure a time unit (for example, a time unit includes one or more time slots, or one or more symbols, but is not limited thereto) as an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol. In the following description, "time unit", "time slot" and "symbol" may be used interchangeably. For ease of description, the following description uses a time slot / symbol as an exemplary time unit. However, it should be understood that the time unit in the present disclosure may also be measured using other time units other than time slots and symbols, such as sub-time slots.

[0088] The UE determines the uplink and downlink transmission direction of each symbol / time slot of a carrier / service cell according to the configuration of the base station. For example, the UE can receive the cell common signaling tdd-UL-DL-ConfigurationCommon to determine whether a time unit is an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol. For example, the following signaling is used for configuration.

[0089]

[0090] The above signaling defines the number of full downlink time slots nrofDownlinkSlots and the number of downlink symbols after the full downlink time slots nrofDownlinkSymbols, as well as the number of full uplink time slots nrofUplinkSlots and the number of uplink symbols before the full uplink time slots nrofUplinkSymbols within the configured period dl-UL-TransmissionPeriodicity. The remaining time slots and symbols are flexible time slots and flexible symbols.

[0091] The UE may also receive UE-specific signaling tdd-UL-DL-ConfigurationDedicated to determine whether a time unit is an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol.

[0092] For example, the following signaling is used for configuration.

[0093]

[0094]

[0095] The above signaling defines the number of downlink symbols nrofDownlinkSymbols and the number of uplink symbols nrofUplinkSymbols in the time slot specified by the time slot index slotIndex, and the remaining symbols in the time slot are flexible symbols. The signaling can also define whether the specified time slot is a downlink time slot of all downlink symbols or an uplink time slot of all uplink symbols through the field allDownlink or allUplink.

[0096] Usually, the same symbol of a carrier / service cell only supports transmission in one direction, i.e., uplink or downlink transmission, so the base station only needs to configure the uplink and downlink transmission directions in the time dimension. The uplink and downlink transmission directions configured by the base station can be periodic, for example, by configuring periodic time slot configuration (Slot Configuration) through high-level signaling, or by configuring the time slot format (Slot Format) within a period of time through dynamic signaling, or by configuring the scheduled resources for uplink transmission or downlink reception through scheduling information (such as DCI scheduling information). The uplink and downlink attributes of each frequency domain resource in each time slot / symbol are determined by the time slot configuration / format: for uplink transmission, for downlink transmission, or for flexible transmission. Flexible time slots / symbols may be used for both uplink and downlink transmission, but can only be used for transmission in one direction at a time.

[0097] In an FDD system, for an uplink carrier / service cell, the base station can configure uplink or flexible transmission symbols / time slots, and for a downlink carrier / service cell, the base station can configure downlink or flexible transmission symbols / time slots. The first-category cell common UL (UpLink, uplink) / DL (DownLink, downlink) information may include information on uplink and downlink attributes in the time dimension. The first-category cell common UL / DL information is associated with the uplink and downlink attributes of the period and the time unit within the period (for example, which time slots / symbols within the period are uplink, downlink or flexible time slots / symbols, respectively), and the uplink and downlink attributes apply to all frequency domain resources within each time slot / symbol of this cell. For example, all frequency domain resources within the bandwidth of this carrier / service cell have the same uplink and downlink attributes within a time slot / symbol.

[0098] According to the present disclosure, in order to allocate uplink and downlink transmission resources more efficiently, the granularity of uplink and downlink transmission resources can be further reduced from all frequency domain resources of a symbol / time slot to part of the frequency domain resources within a symbol / time slot through configuration information. For example, different frequency domain resources in a symbol of a carrier / service cell can be configured with different transmission directions. The configuration information includes cell-common UL / DL information and / or UE-specific UL / DL information. The cell-common UL / DL information may include information on uplink and downlink attributes in the time dimension and the frequency domain dimension. For example, the cell-common UL / DL information can be used to configure which frequency domain resources of which time slots / symbols are uplink, downlink or flexible transmission resources; or, the cell-common UL / DL information can be used to configure which frequency domain resources of which time slots / symbols are uplink, downlink or resources that cannot be used for transmission. The base station can also configure user-specific UL / DL information, for example, configuring user-specific UL / DL information for each service cell of the UE, or configuring user-specific UL / DL information for each BWP (Bandwidth Part) of the UE. According to the configured UL / DL information, the UE can determine that within a symbol or time slot, part of the frequency domain resources are uplink transmission resources and part of the frequency domain resources are downlink transmission resources. Figure 4 As shown, in symbols S1 to S5 and S8 to S12, part of the frequency domain resources are configured as uplink transmission resources, and part of the frequency domain resources are configured as downlink transmission resources. Such symbols or time slots can be called subband multiplexing or subband full multiplexing (SBFD, Subband Full Duplex) symbols or time slots. It can also be determined that within a symbol or time slot, all frequency domain resources are uplink transmission resources, and it can also be determined that within a symbol or time slot, all frequency domain resources are downlink transmission resources. For example, Figure 4 As shown, symbols S6 and S7 are configured as uplink transmission resources, and symbols S13 to S16 are configured as downlink transmission resources. The configuration information may be semi-static signaling, for example, high-layer signaling. For ease of description, the sub-band multiplexing time unit is described below by taking the SBFD symbol / time slot as an example. However, it should be understood that the sub-band multiplexing time unit and its naming are not limited thereto.

[0099] The present disclosure proposes a method performed by a user equipment UE in a wireless communication system. According to one embodiment, the method includes: receiving first configuration information and second configuration information from a base station, the first configuration information being associated with the subband multiplexing of at least one time unit, and the second configuration information being associated with the uplink subband and the downlink subband in the corresponding frequency band of the at least one time unit; and based on the first configuration information and the second configuration information, receiving a downlink signal and / or a channel from the base station in the at least one time unit, and / or sending an uplink signal and / or a channel to the base station. By configuring the subband multiplexing of at least one time unit, and sending and receiving signals / channels according to the subband multiplexing configuration, the UE can make full use of frequency domain resources and reduce latency.

[0100] Figure 5 is an exemplary flowchart of a method executed by a user equipment according to an embodiment of the present disclosure.

[0101] In such Figure 5 In the method 500 shown, in step 501, first configuration information related to the subband configuration of at least one time unit is received from a base station; in step 503, second configuration information associated with the uplink subband and the downlink subband of the at least one time unit is received from the base station; and in step 505, at least one of downlink reception and uplink transmission is performed on the at least one time unit (i.e., the subband multiplexing time unit) based on the first configuration information and the second configuration information.

[0102] It should be understood that, although the above shows a situation where the first configuration information and the second configuration information are received in different steps, the first configuration information and the second configuration information may also be received in the same step.

[0103] The following specifically describes a method for configuring a sub-band multiplexing time unit and a method for performing downlink reception and uplink transmission on the sub-band multiplexing time unit.

[0104] Embodiment 1:

[0105] This embodiment describes a method for configuring a sub-band multiplexing time unit.

[0106] According to an example, the UE receives a first cell common signaling (e.g., cell common signaling tdd-UL-DL-ConfigurationCommon) from a base station, and the first cell common signaling is associated with the uplink and downlink configuration of multiple time units, for example, multiple time slots / symbols are configured as uplink time slots / symbols, downlink time slots / symbols, or flexible time slots / symbols. Then the UE receives a second cell common signaling (e.g., cell common signaling SBFD-configurationCommon, the name of this signaling can also be other names, which are not limited here) from the base station, and the second cell common signaling includes information related to the SBFD configuration of at least one time unit in the above multiple time units. For example, the second cell common signaling can configure which time units in the multiple time units are SBFD time slots / symbols, or the second cell common signaling can configure each time unit in the multiple time units as a SBFD time slot / symbol or a non-SBFD time slot / symbol. The SBFD time slot / symbol determined by the cell common signaling SBFD-configurationCommon belongs to the time slot / symbol determined by the cell common signaling tdd-UL-DL-ConfigurationCommon as at least one of the uplink time slot / symbol, downlink time slot / symbol, and flexible time slot / symbol, which is specifically preset by the protocol. For example, the SBFD time slot / symbol determined by the second cell common signaling may belong to the time slot / symbol determined by the first cell common signaling as a downlink time slot / symbol. Or, for example, the SBFD time slot / symbol determined by the second cell common signaling may belong to the time slot / symbol determined by the first cell common signaling as a flexible time slot / symbol. Or, for example, the SBFD time slot / symbol determined by the second cell common signaling may belong to the time slot / symbol determined by the first cell common signaling as a downlink time slot / symbol or a flexible time slot / symbol. The advantage of using this method is that the tdd-UL-DL-ConfigurationCommon signaling can be backward compatible.

[0107] According to an example, a UE receives a first UE-specific signaling (e.g., tdd-UL-DL-ConfigurationDedicated-r19, the name of the signaling may also be called other names, which are not limited here) from a base station, and the first UE-specific signaling is associated with the uplink, downlink, or SBFD configuration of multiple time units. Because there is no backward compatibility issue for UE-specific signaling, using one signaling to configure each of the multiple time units to be an uplink time slot / symbol, a downlink time slot / symbol, or a SBFD time slot / symbol can save signaling overhead. The following describes a specific implementation method of using one UE-specific signaling to configure one time unit to be an uplink time slot / symbol, a downlink time slot / symbol, or a SBFD time slot / symbol.

[0108] In the first UE-specific signaling, configuration information for configuring each of the multiple time units as an uplink time slot / symbol, a downlink time slot / symbol, or a SBFD time slot / symbol is included. For example, the subband multiplexing time unit may be after the downlink time unit and immediately following the downlink time unit. In other words, the starting position of the subband multiplexing time unit is the time unit next to the downlink time unit. In this case, the configuration information may include information associated with the length of the subband multiplexing time unit. Optionally, the subband multiplexing time unit may be after the downlink time unit and not necessarily immediately following the downlink time unit. In this case, the configuration information may include information associated with the starting position (e.g., starting symbol) of the subband multiplexing time unit and the length of the subband multiplexing time unit (e.g., index).

[0109] Example 1 of the first UE-specific signaling is as follows:

[0110]

[0111] In this example, the nrofDownlinkSymbols field indicates the number of consecutive downlink symbols after the start of the time slot identified by slotIndex. If this field is empty, it can be considered that there are no downlink symbols after the start of the time slot. The nrofUplinkSymbols field indicates the number of consecutive uplink symbols before the end of the time slot identified by slotIndex. If this field is empty, it can be considered that there are no uplink symbols before the end of the time slot. The SBFDstartSymbolAndLength field indicates the index of the start symbol of the SBDF symbol and the length of the SBDF symbol. The SBFD symbol is determined by the index of the start symbol of the SBDF symbol and the length of the SBDF symbol. For example, according to this example, the following can be obtained: Figure 6 The frequency resource configuration shown includes a downlink symbol 601 , a SBFD symbol 602 , and an uplink symbol 603 .

[0112] Example 2 of the first UE-specific signaling is as follows:

[0113] In this example, the nrofDownlinkSymbols field indicates the number of consecutive downlink symbols after the start of the timeslot identified by slotIndex. If this field is missing, it is assumed that there are no downlink symbols after the start of the timeslot. The nrofUplinkSymbols field indicates the number of consecutive uplink symbols before the end of the timeslot identified by slotIndex. If this field is missing, it is assumed that there are no uplink symbols before the end of the timeslot. The nrofSBFDSymbols field indicates the number of consecutive SBFD symbols after the end of the downlink symbol in the timeslot.

[0114] In this example, the SBFD symbol is after the end of the downlink symbol and immediately follows the downlink symbol, so the configuration information does not need to configure the index of the starting symbol of the SBFD symbol, but determines the SBFD symbol by only setting the number of consecutive SBFD symbols after the end of the downlink symbol. For example, according to this example, the following can be obtained: Figure 7 The frequency resource configuration shown includes downlink symbols 701 , SBFD symbols 702 , and uplink symbols 703 .

[0115] Example 3 of the first UE-specific signaling is as follows:

[0116]

[0117] Example 4 of the first UE-specific signaling is as follows:

[0118]

[0119]

[0120] The above-mentioned Examples 3 and 4 are similar to Examples 2 and 1 respectively, except that Examples 3 and 4 explicitly show a time slot configuration in which all time slots are SBFD symbols, while Examples 2 and 1 implicitly show a time slot configuration in which all time slots are SBFD symbols.

[0121] In the method using the first UE-specific signaling, since the first UE-specific signaling is UE-specific signaling, there is no backward compatibility problem and configuration signaling is saved.

[0122] Optionally, configuration can also be performed through two UE-specific signalings. In this case, the UE receives a second UE-specific signaling (e.g., tdd-UL-DL-ConfigurationDedicated) related to the uplink and downlink configuration of multiple time units from the base station. For example, the second UE-specific signaling configures each of the multiple time units as an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol. Then, the UE receives a third UE-specific signaling (e.g., SBFD-configurationDedicated, the name of this signaling can also be other names, which are not limited here) from the base station. The third UE-specific signaling includes information related to the SBFD configuration of at least one time unit in the above-mentioned multiple time units. For example, the third UE-specific signaling can configure which time units in the multiple time units are SBFD time slots / symbols, or the third UE-specific signaling can configure whether each time unit in the multiple time units is a SBFD time slot / symbol or a non-SBFD time slot / symbol.

[0123] The third UE-specific signaling configures whether a time unit is an SBFD time slot / symbol as follows. In this example, the SBFDstartSymbolAndLength field indicates the index of the start symbol of the SBDF symbol and the length of the SBDF symbol. The SBFD symbol is determined by the index of the start symbol of the SBDF symbol and the length of the SBDF symbol.

[0124]

[0125] Embodiment 2:

[0126] This embodiment describes a method for determining to perform downlink reception and uplink transmission on symbols configured with full sub-band multiplexing.

[0127] According to exemplary method 1, on the SBFD symbol configured by the UE receiving signaling, if there is no conflict of simultaneous reception and transmission (that is, according to the signaling, the UE is to receive on the SBFD symbol or to transmit on the SFBD symbol, and will not receive and transmit on the SBFD symbol at the same time according to the signaling), if the UE is to receive on the SBFD symbol according to the signaling, the UE receives the SBFD symbol as a downlink symbol configured by the high-level signaling, that is, no matter the DCI format 2_0 configures the SBFD symbol as a downlink symbol, an uplink symbol or a flexible symbol, the UE will receive on the SBFD symbol. If the UE is to transmit on the SBFD symbol according to the signaling, the UE transmits the SBFD symbol as an uplink symbol configured by the high-level signaling, that is, no matter the DCI format 2_0 configures the SBFD symbol as a downlink symbol, an uplink symbol or a flexible symbol, the UE will transmit on the SBFD symbol.

[0128] That is, according to this method, when receiving the reception signaling that the UE is to receive in the SBFD symbol and not receiving the transmission signaling that the UE is to send in the SBFD symbol, the UE receives on the downlink subband of the SBFD symbol. Similarly, when receiving the transmission signaling that the UE is to send in the SBFD symbol and not receiving the reception signaling that the UE is to receive in the SBFD symbol, the UE transmits on the uplink subband of the SBFD symbol.

[0129] UE reception includes receiving PDSCH scheduled by DCI and receiving Channel State Information-Reference Signal (CSI-RS) requested by DCI. These two types of reception are dynamically driven. UE reception also includes receiving (or detecting) Physical Downlink Control Channel (PDCCH), CSI-RS configured by high-level signaling, and Semi-persistent Scheduling (SPS) PDSCH, etc. These types of reception are semi-statically configured and semi-persistently configured. UE transmission includes sending PUSCH scheduled by DCI, sending PUCCH driven by DCI, and sending SRS requested by DCI. These types of transmission are dynamically driven. UE transmission also includes sending SRS, CG PUSCH and PUCCH configured by high-level signaling, etc. These types of transmission are semi-statically configured and semi-persistently configured.

[0130] The above-mentioned UE receiving according to the SBFD symbol being a downlink symbol configured by high-level signaling means: when deciding whether to receive on the configured SBFD symbol, the SBFD symbol is received as the downlink symbol configured by the high-level signaling; and when determining the available frequency domain resources when receiving on the SBFD symbol, the downlink resources configured in the SBFD symbol are received as the available frequency domain resources for reception. The above-mentioned UE sending according to the SBFD symbol being an uplink symbol configured by high-level signaling means: when deciding whether to send on the configured SBFD symbol, the SBFD symbol is sent as the uplink symbol configured by the high-level signaling; and when determining the available frequency domain resources when sending on the SBFD symbol, the uplink resources configured in the SBFD symbol are sent as the available frequency domain resources for sending.

[0131] For example, the UE receives semi-static signaling to configure symbol n as a SBFD symbol, the SBFD symbol includes an uplink subband (uplink subband(s)) and a downlink subband (downlink subband(s)), the UE receives high-level signaling to configure the CSI-RS to be received in symbol n, the UE does not receive any signaling sent on symbol n, and DCI format 2_0 configures the SBFD symbol n as a flexible symbol. In this case, the UE receives CSI-RS in symbol n. When receiving CSI-RS, the UE only receives CSI-RS in the downlink subband of the SBFD symbol.

[0132] For example, the UE receives semi-static signaling to configure symbol m as a SBFD symbol, the SBFD symbol includes an uplink subband (uplink subband(s)) and a downlink subband (downlink subband(s)), the UE receives high-level signaling to configure the CG PUSCH to be sent in symbol m, the UE does not receive any signaling on symbol m, and DCI format 2_0 configures the SBFD symbol m as a flexible symbol. In this case, the UE sends CG PUSCH in symbol m. When sending CG PUSCH, the UE only sends CG PUSCH in the uplink subband of the SBFD symbol.

[0133] This method can make full use of frequency domain resources.

[0134] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by the second cell common signaling (e.g., SBFD-configurationCommon) received by the UE, and the SBFD time slot / symbol is a downlink time slot / symbol (or uplink time slot / symbol) determined by the first cell common signaling (e.g., tdd-UL-DL-ConfigurationCommon), downlink data and control signaling can be received (or uplink data and control signaling can be sent) on the SBFD time slot / symbol according to the above method one.

[0135] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by the second cell common signaling (e.g., SBFD-configurationCommon) received by the UE, and the SBFD time slot / symbol is a flexible time slot / symbol determined by the first cell common signaling (e.g., tdd-UL-DL-ConfigurationCommon), downlink data and control signaling can be received or uplink data and control signaling can be sent on the SBFD time slot / symbol according to the above method one.

[0136] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by the first UE-specific signaling (e.g., tdd-UL-DL-ConfigurationDedicated-r19) received by the UE, downlink data and control signaling can be received or uplink data and control signaling can be sent on the SBFD time slot / symbol according to the above method 1.

[0137] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by a third UE-specific signaling (e.g., SBFD-configurationDedicated) received by the UE, downlink data and control signaling can be received or uplink data and control signaling can be sent on the SBFD time slot / symbol according to the above method one.

[0138] According to exemplary method two, for the SBFD symbol configured by the UE receiving signaling, the UE determines whether the SBFD symbol is sent or received as a downlink symbol, an uplink symbol or a flexible symbol based on the information related to the uplink and downlink configuration of the SBFD symbol in at least one of the first cell common signaling (tdd-UL-DL-ConfigurationCommon), the second UE-specific signaling (tdd-UL-DL-ConfigurationDedicated), the DCI format 2_0 and the DCI scheduling information.

[0139] The above-mentioned UE receiving according to the SBFD symbol being a downlink symbol means: when deciding whether to receive on the configured SBFD symbol, the SBFD symbol is received as a downlink symbol; and when determining the available frequency domain resources when receiving on the SBFD symbol, the downlink resources configured in the SBFD symbol are received as available frequency domain resources. The above-mentioned UE transmitting according to the SBFD symbol being an uplink symbol means: when deciding whether to transmit on the configured SBFD symbol, the SBFD symbol is transmitted as an uplink symbol; and when determining the available frequency domain resources when transmitting on the SBFD symbol, the uplink resources configured in the SBFD symbol are transmitted as available frequency domain resources. The above-mentioned UE sending or receiving according to the SBFD symbol being a flexible symbol means: when deciding whether to send or receive on the configured SBFD symbol, the SBFD symbol is sent or received as a flexible symbol; and when determining the available frequency domain resources when sending or receiving on the SBFD symbol, the uplink resources configured in the SBFD symbol are sent as available frequency domain resources or the downlink resources configured in the SBFD symbol are received as available frequency domain resources. The advantage of adopting this method is that there will be no conflict between uplink sending and downlink receiving.

[0140] For example, when the configured SBFD symbol is a downlink symbol configured by tdd-UL-DL-ConfigurationCommon signaling, the UE receives the SBFD symbol as a downlink symbol, that is, the UE can receive the CSI-RS configured by high-layer signaling, receive (detect) PDCCH and receive SPS PDSCH in the SBFD symbol.

[0141] For example, when the configured SBFD symbol is an uplink symbol configured by tdd-UL-DL-ConfigurationCommon signaling, the UE sends according to the SBFD symbol as the uplink symbol, that is, the UE can send the SRS configured by the high-level signaling in the SBFD symbol, send the configuration allocation (CG, Configure Grant) PUSCH, and transmit the PUCCH of the HARQ-ACK of the SPS PDSCH.

[0142] The advantage of adopting this method is that there will be no conflict between uplink transmission and downlink reception.

[0143] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by the second cell common signaling (e.g., SBFD-configurationCommon) received by the UE, and the SBFD time slot / symbol is a downlink time slot / symbol (or uplink time slot / symbol) determined by the first cell common signaling (e.g., tdd-UL-DL-ConfigurationCommon), downlink data and control signaling can be received (or uplink data and control signaling can be sent) on the SBFD time slot / symbol according to method two.

[0144] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by the second cell common signaling (e.g., SBFD-configurationCommon) received by the UE, and the SBFD time slot / symbol is a flexible time slot / symbol determined by the first cell common signaling (e.g., tdd-UL-DL-ConfigurationCommon), downlink data and control signaling can be received or uplink data and control signaling can be sent on the SBFD time slot / symbol according to method two.

[0145] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by the first UE-specific signaling (e.g., tdd-UL-DL-ConfigurationDedicated-r19) received by the UE, downlink data and control signaling can be received or uplink data and control signaling can be sent on the SBFD time slot / symbol according to method two.

[0146] For example, when the SBFD time slot / symbol is a SBFD time slot / symbol determined by a third UE-specific signaling (e.g., SBFD-configurationDedicated) received by the UE, downlink data and control signaling can be received or uplink data and control signaling can be sent on the SBFD time slot / symbol according to method two.

[0147] In the embodiments of the present disclosure, the UE receives the PDSCH scheduled by the DCI and receives the Channel State Information-Reference Signal (CSI-RS) requested by the DCI. These two types of reception are dynamically driven.

[0148] UE reception also includes receiving (detecting) the physical downlink control channel (PDCCH), the CSI-RS configured by high-level signaling, and the semi-persistent (SPS) PDSCH, etc. These types of reception are semi-statically configured and semi-persistently configured.

[0149] For dynamically driven reception, the UE can receive on the SBFD time slot / symbol. At this time, regardless of whether the SBFD time slot / symbol is an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol determined by the first cell common signaling (e.g., tdd-UL-DL-ConfigurationCommon), the UE receives on the SBFD time slot / symbol. Alternatively, regardless of whether the SBFD time slot / symbol is an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol determined by the second UE-specific signaling (e.g., tdd-UL-DL-ConfigurationDedicated), the UE receives on the SBFD time slot / symbol. Alternatively, regardless of whether the SBFD time slot / symbol is a downlink symbol, an uplink symbol, or a flexible symbol configured by DCI format 2_0, the UE receives on the SBFD time slot / symbol.

[0150] For reception of semi-static configuration and semi-continuous configuration, the UE can receive on the SBFD time slot / symbol only when the SBFD time slot / symbol is a downlink time slot / symbol determined by the first cell common signaling (for example, tdd-UL-DL-ConfigurationCommon), or the SBFD time slot / symbol is a downlink time slot / symbol determined by the second UE-specific signaling (for example, tdd-UL-DL-ConfigurationDedicated), or the SBFD time slot / symbol is a downlink symbol configured by DCI format 2_0, or the SBFD time slot / symbol is a downlink symbol configured by scheduling DCI (or DCI scheduling information).

[0151] In the embodiments of the present disclosure, the UE sends a PUSCH scheduled by DCI, a PUCCH driven by DCI, and an SRS requested by DCI. These transmissions are dynamically driven.

[0152] UE transmission also includes SRS, CG PUSCH and PUCCH configured by high-level signaling. These transmissions are semi-statically configured and semi-continuously configured.

[0153] For dynamically driven transmission, the UE can transmit on the SBFD time slot / symbol. At this time, regardless of whether the SBFD time slot / symbol is an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol determined by the first cell common signaling (e.g., tdd-UL-DL-ConfigurationCommon), the UE transmits on the SBFD time slot / symbol. Alternatively, regardless of whether the SBFD time slot / symbol is an uplink time slot / symbol, a downlink time slot / symbol, or a flexible time slot / symbol determined by the second UE-specific signaling (e.g., tdd-UL-DL-ConfigurationDedicated), the UE transmits on the SBFD time slot / symbol. Regardless of whether the SBFD time slot / symbol is a downlink symbol, an uplink symbol, or a flexible symbol configured by DCI format 2_0, the UE transmits on the SBFD time slot / symbol.

[0154] For the transmission of semi-static configuration and semi-continuous configuration, the UE can transmit on the SBFD time slot / symbol only when the SBFD time slot / symbol is the uplink time slot / symbol determined by the first cell common signaling (for example, tdd-UL-DL-ConfigurationCommon), or the SBFD time slot / symbol is the uplink time slot / symbol determined by the second UE-specific signaling (for example, tdd-UL-DL-ConfigurationDedicated), or the SBFD time slot / symbol is the uplink symbol configured by DCI format 2_0, or the SBFD time slot / symbol is the uplink symbol configured by the scheduling DCI (or DCI scheduling information).

[0155] The above method described in the present disclosure may be executed by a UE including a transceiver and a processor. Figure 8 FIG. 4 shows an exemplary structure of a UE according to the present disclosure. Figure 8 As shown, the UE includes a transceiver 810 and a processor 820 coupled to the transceiver 810.

[0156] The above describes the UE and the method executed by the UE according to the embodiments of the present disclosure. It should be understood that the base station that executes the corresponding steps and the corresponding method executed by the base station are also included in the scope of the present application.

[0157] According to an exemplary embodiment, a method performed by a base station in a wireless communication system may include: sending first configuration information to a user equipment UE, the first configuration information being used to configure at least one time unit among a plurality of time units as a subband multiplexing time unit; and sending second configuration information to the UE, the second configuration information being used to configure an uplink subband and a downlink subband of the subband multiplexing time unit; wherein the UE is configured to perform at least one of downlink reception and uplink transmission on the subband multiplexing time unit based on the first configuration information and the second configuration information.

[0158] According to an exemplary embodiment, sending first configuration information to the UE may include: sending first cell common signaling to the UE, the first cell common signaling including information configuring each of multiple time units as an uplink time unit, a downlink time unit or a flexible time unit; and sending second cell common signaling to the UE, the second cell common signaling including first configuration information configuring at least one time unit among the multiple time units as a subband multiplexing time unit.

[0159] According to an exemplary embodiment, sending first configuration information to the UE may include: sending first UE-specific signaling to the UE, the first UE-specific signaling including first configuration information for configuring each of a plurality of time units as an uplink time unit, a downlink time unit, or a sub-band multiplexing time unit, wherein the first configuration information configures at least one time unit among the plurality of time units as a sub-band multiplexing time unit.
