Frame structure configuration

Abstract

The present disclosure relates to a device, a method, an apparatus, and a computer-readable storage medium for providing cell search. The method includes determining a cell search pattern, the pattern indicating that the cell search is performed in parallel on carriers associated with at least one of a second frequency range (FR2) in New Radio (NR) and a first frequency range (FR1) in Long Term Evolution (LTE) or NR, or that the cell search is performed on carriers associated with at least one of LTE or FR1 being searched before carriers in FR2, and performing the cell search based on the determined pattern. The approach proposed in the present disclosure can allow time for a user equipment (UE) to perform a cell search taking into account the maximum number of configured carriers without unnecessarily extending the allowed search time, thereby avoiding unnecessary long UE delays.

Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the field of telecommunications, and more particularly, to devices, methods, apparatuses, and computer-readable storage media for enhancing frame structure configuration.

Background Art

[0002] In a communication system, two main multiplexing modes, namely Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD), are used for uplink (UL) transmission and downlink (DL) transmission. In FDD, paired bands are used for simultaneous DL and UL transmission, with a guard band in between. In TDD, unpaired bands are used, and the resources are divided in the time domain into different symbols or slots for DL transmission and UL transmission respectively. When allocating a time slot for UL in TDD, coverage and capacity decrease, and latency also increases.

[0003] From such a background, in 5G New Radio (NR), an evolution of multiplexing that enables simultaneous DL and UL transmission with different Physical Resource Blocks (PRBs) within the unpaired band of a cell has been proposed.

Furthermore, communication between terminal equipment and network equipment in a communication network may be carried out in accordance with any appropriate generation of communication protocol, including but not limited to first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, and fifth-generation (5G) New Radio (NR) communication protocols, and / or other protocols currently known or to be developed in the future. Embodiments of this disclosure can be applied to a variety of communication systems. Given the rapid development of communications, there will of course be future communication technologies and systems to which this disclosure can be embodied. The scope of this disclosure should not be considered to be limited to the aforementioned systems only.

[0024] As used herein, the term “network equipment” refers to a node in a communications network from which terminal equipment accesses the network and receives services. Depending on the terminology and technology applied, network equipment may refer to base stations (BS) or access points (APs), such as Node B (NodeB, or NB), Evolutionary Node B (eNodeB, or eNB), Next Generation Node B (NR NB), Remote Radio Unit (RRU), Radio Header (RH), Remote Radio Head (RRH), Integrated Access Backhaul (IAB) node, and low-power nodes such as relays, femto, and pico. Network equipment may also be defined as part of a gNB, for example, in a CU / DU split, in which case the network equipment is defined as either a gNB-CU or a gNB-DU.

[0025] The term "terminal equipment" refers to any terminal equipment capable of wireless communication. Examples, though not limited to, include communication equipment, user equipment (UE), subscriber station (SS), mobile subscriber station, mobile station (MS), or access terminal (AT). Terminal devices include, but are not limited to, mobile phones, cellular phones, smartphones, voice over IP (VoIP) phones, wireless local loop phones, tablets, wearable devices, personal digital assistants (PDAs), portable computers, desktop computers, image capture devices such as digital cameras, game consoles, music storage and playback devices, in-vehicle wireless terminal devices, wireless endpoints, mobile stations, laptop embedded devices (LEEs), laptop-mounted devices (LMEs), USB dongles, smart devices, wireless home equipment (CPEs), Internet of Things (IoT) devices, wearables such as watches, head-mounted displays (HMDs), vehicles, drones, medical devices and applications (e.g., remote surgery), industrial devices and applications (e.g., robots and / or other wireless devices operating in the context of industrial and / or automated processing chains), consumer electronics devices, and devices operating on commercial and / or industrial wireless networks. Terminal devices may also correspond to mobile terminal (MT) units of integrated access backhaul (IAB) nodes (relay nodes).

[0026] The functions described in this embodiment may be performed in fixed network nodes and / or wireless network nodes in various exemplary embodiments, but in other exemplary embodiments, the functions may be implemented in user equipment (such as a mobile phone, or tablet computer, or laptop computer, or desktop computer, or mobile IoT device, or fixed IoT device).

Examples of such functions include bootstrap server functions and / or home subscriber servers, which can be implemented in user equipment by providing user equipment with software configured to run on the user equipment in terms of these functions / nodes.

[0027] To enable simultaneous DL and UL transmission in unpaired broadband PRBs of NR cells, a combination of TDD and FDD has been proposed, sometimes called the subband non-overlapping full-duplex (SBFD) scheme. In SBFD, at least a portion of the resources set up for DL ​​transmission in the time domain may be allocated to UL transmission dynamically or semi-statistically. In other words, the SBFD frame takes the form of UL-DL PRB splitting.

[0028] Implementing SBFD frames presents several challenges. First, since the location and size of such UL-DL subbands may not be fixed, the UE needs to recognize the time and frequency location of the subbands used for SBFD operation in relation to the gNB. Therefore, signaling of the SBFD frame configuration is necessary.

[0029] Backward compatibility must be ensured with gNBs or UEs that support only normal TDD or FDD operation. gNBs or corresponding cells that support SBFD operation are expected to coexist with other gNBs or cells that support only normal TDD operation, both in terms of same-channel (i.e., cells deployed on the same carrier frequency, such as belonging to the same operator) and adjacent-channel (i.e., cells deployed on adjacent carrier frequencies, such as belonging to different operators). Furthermore, existing 5G UEs that cannot be upgraded to support SBFD-specific features can provide services on SBFD-enabled cells without experiencing performance degradation compared to performance on normal TDD cells, for example.

[0030] To address the above and other potential problems, embodiments of the present disclosure provide solutions for SBFD frame structures and associated configurations. The configuration of UL-DL PRB splitting is flexible, meaning that the location and size of UL-DL resources or subbands may be configured, for example, at the cell level or operator level, or may change over time in individual cells. For this reason, one or more signalings are enabled by the gNB to configure UL-DL PRB splitting, for example, by configuring (activating or deactivating) one or more UL subbands. Furthermore, asymmetric SBFD subframe configurations are also possible by assigning TDD patterns 1 and 2 with different subband configurations. In some exemplary embodiments of the present disclosure, the terms “UL-DL PRB splitting” and “UL subbands” may be used interchangeably.

[0031] Figure 1 shows an exemplary network system 100 in which exemplary embodiments of the present disclosure may be implemented. As shown in Figure 1, the communication network 100 may comprise a first device 110 and a second device 120. The first device 110 may be a terminal device (e.g., a UE). The second device 120 may be a network device (e.g., a gNB) that provides services to the terminal device, e.g., the first device 110 located in a cell 102. Hereinafter, the first device 110 may also be referred to as the UE 110, and the second device 120 may also be referred to as the gNB 120.

[0032] The first device 110 and the second device 120 can communicate with each other based on a standard FDD, standard TDD, or SBFD scheme. In the context of this disclosure, the SBFD scheme may be referred to as cross-division duplex (xDD), flexible duplex (FDU), etc. The link from the first device 110 to the second device 120 is called UL, and the link from the second device 120 to the first device 110 is called DL.

[0033] In TDD, the second device 120 can instruct the first device 110 to configure the TDD-UL-DL pattern. In particular, the second device 10 can configure or instruct a unit time resource (e.g., a symbol or slot) as "DL", "UL", or "flexible" via the RRC configuration. There is a common pattern that is broadcast as part of the system information of TDD-UL-DL-ConfigCommon and received accordingly by all UEs in cell 102.

[0034] Figures 2A and 2B show exemplary configurations of TDD patterns suitable for embodiments of the present disclosure. As shown in Figure 2A, TDD-UL-DL-Pattern 200 is configured via TDD-UL-DL-ConfigCommon, which may be either Pattern 1 or Pattern 2. As shown in Figure 2B, TDD-UL-DL-Pattern 202 is configured via TDD-UL-DL-ConfigCommon, and may consist of two concatenated patterns, i.e., both Pattern 1 and Pattern 2, repeated in the time domain. The PRB of the symbol has the same string, "D" for DL, "F" for flexible, or "U" for UL. The configured pattern includes the DL phase first, the UL phase last, and what remains in between is designated "flexible". This flexible symbol is intended to be used flexibly for either UL or DL ​​and may follow one of the following gNB decisions. UL transmission or DL ​​reception is dynamically scheduled to the UE using scheduling downlink control information (DCI), such as DCI format 0_x for UL and DCI format 1_x for DL ​​(where x represents 0, 1, or 2). The TDD-UL-DL-ConfigDedicated wireless resource control (RRC) provides additional UE-specific configuration signaling that further designates some or all of the flexible symbols of TDD-UL-DL-ConfigCommon as DL or UL, semi-statically. Send DCI format 2_0 (i.e., SFI), and further specify the “flexible” symbol remaining after the common RRC setting and dedicated RRC setting as DL or UL.

[0035] In some exemplary embodiments, the second device 120 can instruct the first device 110 to configure a UL-DL split or subband configuration. This makes it possible to convert some of the resources originally allocated as DL or flexible to UL. In the context of this disclosure, a UL-DL split refers to a set of UL resources or subbands (e.g., RE, PRB) that are converted from at least a set of DL and flexible symbols to include a set of resource elements that can be used for UL transmission. In the SBFD scheme, an SBFD UL subband is created on DL (and possibly flexible) symbols within the full carrier or BWP bandwidth. In this way, it is supported to dynamically adjust the subband configuration to, for example, traffic demand.

[0036] In the following, embodiments may be described in conjunction with the TDD method, but it should be understood that the SBFD frame configuration and UL-DL split provided in this disclosure are also applicable to the FDD method. Therefore, this disclosure is not limited in this respect.

[0037] Furthermore, please understand that the number of network devices and terminal devices shown in Figure 1 are given for illustrative purposes only and do not imply any limitations. The communication network 100 may include any appropriate number of network devices and terminal devices.

[0038] Depending on the communication technology, the communication network 100 may be a code division multiple access (CDMA) network, a time division multiple access (TDMA) network, a frequency division multiple access (FDMA) network, an orthogonal frequency division multiple access (OFDMA) network, a single carrier frequency division multiple access (SC-FDMA) network, or other. The communications discussed in network 100 may conform to any appropriate standard, including but not limited to New Radio Access (NR), Long-Term Evolution (LTE), LTE Evolution, LTE Advanced (LTE-A), Broadband Code Division Multiple Access (WCDMA®), Code Division Multiple Access (CDMA), cdma2000, and the Mobile Communications Global System (GSM). Furthermore, communications may be performed according to any generation of communication protocols currently known or to be developed in the future. Examples of communication protocols include, but are not limited to, first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, and fifth-generation (5G) communication protocols. The technologies described herein can be used not only with the above-mentioned wireless networks and technologies but also with other wireless networks and technologies. For clarity, one aspect of the technology will be described below as LTE, and the term LTE will be used in much of the following description.

[0039] The principles and embodiments of this disclosure will be described in detail below with reference to Figures 3 to 8. Figure 3 is a signaling chart showing an exemplary process 300 for frequency-time resource configuration in some exemplary embodiments of this disclosure. Process 300 may include a first device 110 and a second device 120, as shown in Figure 1. For illustrative purposes, process 300 will be described with reference to Figure 1.

[0040] As an example, process 300 may be implemented in a scenario in which a first device 110 and a second device 120 communicate in FDD or TDD mode. In process 300, the second device 120 transmits first configuration information 305 that specifies a set of resources for TDD or FDD communication between the first device 110 and the second device 120. The set of resources may include a first subset of resources for uplink transmission.

[0041] For example, the first configuration information may be a TDD-UL-DL pattern indicated via TDD-UL-DL-ConfigCommon. TDD-UL-DL-ConfigCommon may be included in the RRC System Information Broadcast (SIB). In the case of TDD, the set of resources may be symbols or slots for DL ​​and UL transmissions allocated in the TDD-UL-DL pattern, and the first subset of resources may be UL symbols or slots.

[0042] In some cases, in addition to TDD-UL-DL-ConfigCommon, the second device 120 may also send TDD-UL-DL-ConfigDedicated, for example, DDDDU, to maintain backward compatibility.

[0043] The second device 120 transmits second configuration information 310 indicating at least one second subset of resources for uplink transmission. In this case, the at least one second subset of resources is configured as a UL-DL split and includes at least one resource other than the first subset of resources. The second configuration information may be included, for example, in an SIB, RRC message, etc.

[0044] In the context of this disclosure, a first subset of resources may refer to at least one UL slot or symbol in one or more TDD-UL-DL patterns. A second subset of resources may refer to one or more subbands allocated for UL transmission in at least one DL (or flexible) slot or symbol in one or more TDD-UL-DL patterns. For example, a total of four subbands may be set up, e.g., SBFD_UL_subband1, ..., SBFD_UL_subband4, where SBFD_UL_subband1 is allocated to TDD pattern 1, and SBFD_UL_subband1 and SBFD_UL_subband3 are allocated to TDD pattern 2, i.e., the same subband can be allocated to one or more TDD patterns, and not all subbands need to be allocated to one or more TDD patterns.

[0045] In exemplary embodiments, a first subset of resources may not overlap with at least one second subset of resources. Alternatively, in some other embodiments, at least a portion of the first subset of resources may overlap with at least one second subset of resources. Therefore, the scope of this disclosure is not limited in this respect.

[0046] Here, with reference to Figures 4A to 4C, the SBFD resource configuration according to the embodiments of the present disclosure will be described. It should be understood that the time-domain and frequency-domain resource units are given for illustrative purposes only and without suggesting a classification approach of the first type of classification model. In the examples shown in Figures 4A to 4E, the time resource unit may be a symbol or a slot, and the frequency resource unit may be a subcarrier, but any other resource unit or resolution may also be suitable for implementing the SBFD resource configuration.

[0047] In an exemplary embodiment, the second setting information is: A first instruction for one start frequency resource and start time resource of at least one second subset of resources, The second set of resources includes the second instruction for the end frequency resource and the end time resource, It can include...

[0048] Therefore, the second configuration information may be in the form of two tuples [symbol, PRB] indicating the start and end positions of each UL subband, respectively. Figure 4A shows a schematic diagram of an exemplary configuration 400 of the UL subbands in some exemplary embodiments of the present disclosure. As indicated by the first configuration instruction, slots 401 to 404 are allocated for DL ​​transmission and slot 405 is allocated for UL transmission. The second configuration instruction may indicate UL-DL splits 406 and 407 corresponding to subbands 1 and 2 for UL transmission, which are indicated by RE / rectangle symbols.

[0049] The positions and sizes of UL-DL splits 406 and 407 can be determined based on the start and end points of the corresponding subbands in both the time domain and the frequency domain, i.e., the two opposing vertices of the RE / rectangle symbol. Thus, the start and end positions of UL subband 1 can be indicated by [first time index, first frequency index] and [second time index, second frequency index], respectively. The start and end positions of UL subband 2 can be indicated similarly.

[0050] In some exemplary embodiments, the second configuration information may include a start frequency resource and a start time resource from at least one second subset of resources, a first number of frequency resources within the second subset, and a second number of time resources within the second subset. Figure 4B shows a schematic diagram of an exemplary configuration 410 of the UL subband in some exemplary embodiments of the present disclosure. Similar to configuration 400, as indicated by the first configuration information, slots 401 to 404 are allocated for DL ​​transmission and slot 405 is allocated for UL transmission. The second configuration instruction indicates UL-DL splits 406 and 407 corresponding to subbands 1 and 2 for UL transmission, which are indicated by RE / rectangle symbols.

[0051] The respective positions and sizes of UL-DL splits 406 and 407 can be determined based on the starting positions of the corresponding subbands in both the time and frequency domains, as well as the bandwidth and duration of the subbands. Thus, the starting position of UL subband 1 may be indicated by [first time index, first frequency index]. The bandwidth may be indicated by the number of frequency resources (e.g., PRBs) in the frequency domain, and the duration may be indicated by the number of time resources (e.g., symbols, slots, etc.) in the time domain.

[0052] In some exemplary embodiments, at least one second subset of resources may include a first target subset of resources and a second target subset of resources. In these embodiments, the second configuration information is: The start frequency resource and start time resource of the first target subset of the resource, and the third instruction of the first bandwidth of the first uplink subband corresponding to the first target subset of the resource. The start frequency resource and start time resource of the second target subset of the resource, and the fourth instruction of the second bandwidth of the second uplink subband corresponding to the second target subset of the resource, It may include.

[0053] In the above case, the start time resource of the second target subset of the resource may be the first symbol following the end time resource of the first target subset of the resource in the time domain. Figure 4C shows a schematic diagram of an exemplary configuration 420 of the UL subband in some exemplary embodiments of the present disclosure. Similar to configurations 400 and 410, slots 401 to 404 are allocated for DL ​​transmission and slot 405 is allocated for UL transmission, as indicated by the first configuration information. The second configuration instruction indicates UL-DL splits 406 and 407 corresponding to subbands 1 and 2 for UL transmission.

[0054] As shown in Figure 4C, each of subbands 1 and 2 is represented by a starting PRB, a starting symbol, and a bandwidth. The starting PRB and starting symbol can be represented as [first time index, first frequency index]. The starting PRB and bandwidth allow for the allocation of the frequency domain to each subband. For the allocation of the time domain, the last symbol of the last subband (i.e., subband 2) is fixed in the time domain, and a specific symbol can be designated, for example, the last DL symbol of an S slot, or the last symbol of an S slot. Therefore, the last symbol of another subband (i.e., subband 1) becomes the starting symbol of the next subband (i.e., subband 2). In this way, the time domain allocation for each subband can be derived based on the set starting symbols of each subband.

[0055] In an exemplary embodiment, the second setting information is: A first resource index (RIV) value indicating the number of starting frequency resources and frequency resources in at least one of the second subsets of the resources, The second RIV indicates the start time and duration of the time resource within the second subset of resources, It may include.

[0056] In the embodiments described above, the frequency-time square corresponding to the UL-DL split is shown in a similar manner to how physical uplink shared channel (PUSCH) resource allocation is provided. The RIV jointly provides the starting PRB and number of PRBs within the active bandwidth section (BWP) or the common RB (CRB) grid. Furthermore, the corresponding start and length indicator values ​​(SLIV) jointly provide the start position and duration within the TDD-UL-DL pattern.

[0057] In some exemplary embodiments, the first device 110 can determine a third subset 315 of resources, including first and second subsets of resources, based on first and second configuration information. Based on the received information, the UE can determine the respective UL direction, DL direction, or UL-DL split for each resource in the time and frequency grid, as described later in relation to Figure 6A.

[0058] Therefore, the first device 110 can transmit data to the second device 120 using a third subset of resources.

[0059] Semi-statistical signaling for SBFD configuration has been described above. Dynamic signaling for SBFD configuration will be described in detail below, and can be used in conjunction with semi-statistical signaling. In this case, the second configuration information may indicate the allocation of at least one second subset of resources in at least the frequency domain. The second device 120 may further send a configuration message 325 to the first device 110 to instruct the activation or deactivation of at least one second subset of resources in the time domain. The configuration message may be sent by signaling of a lower layer, such as DCI or a media access control (MAC) control element (CE).

[0060] In some exemplary embodiments, such configuration messages may be used to activate or deactivate each of the individual subbands corresponding to at least one second subset of the resources.

[0061] In the above embodiment, after receiving a configuration message, the first device 110 can determine whether the configuration message includes a first instruction to activate at least a first portion of at least one second subset of the resources, or a second instruction to deactivate at least a second portion of at least one second subset of the resources (330).

[0062] If the configuration message includes a first instruction, the first device 110 may determine a third subset of resources allocated for uplink transmission based on the first instruction. In this case, the third subset of resources may include the first subset of resources and at least the first part of at least one second subset of resources. Thus, the first device 110 can send data transmissions to the second device 120 using the third subset of resources (335).

[0063] Otherwise, if the configuration message includes a second instruction, the first device 110 may determine, based on the second instruction, a fourth subset of resources allocated for uplink transmission. In this case, the fourth subset of resources may include the first subset of resources and the remaining portion of at least one second subset of resources, excluding at least the second portion. Thus, the first device 110 can transmit to the second device 120 (340).

[0064] In the case of frequency domain allocation, the second configuration information may include the start frequency resource and bandwidth of the uplink subband corresponding to one of at least one second subset of the resource. Alternatively, the second configuration information may include the start frequency resource and end frequency resource of the uplink subband corresponding to a second subset of the resource. In the case of time domain allocation, the first configuration information may indicate the TDD-UL-DL pattern of the first device 110. Furthermore, the configuration message may include an indication of at least one slot of the TDD-UL-DL pattern to which the uplink subband is to be applied.

[0065] In some exemplary embodiments, the display may be a bitmap for indicating the D and / or S slots of the TDD-UL-DL pattern to which the set or active UL subbands are applied. If multiple UL subbands are applied, the active subbands must be indicated, as will be discussed later. In this case, the UL resources are assumed to start with the first symbol of each indicated slot, or the starting symbol of the first indicated slot is set, and the other indicated slots are assumed to convert all DL symbols and / or flexible symbols as SBFD symbols.

[0066] In some exemplary embodiments, the bitmap has a number of bits corresponding to the number of D slots and S slots in the TDD-UL-DL pattern. For example, in the TDD-UL-DL pattern "DDDSU", the bitmap to indicate that the active subbands are applicable to the second and third D slots and S slots may be 0111.

[0067] Figure 5A shows a schematic diagram of an exemplary configuration 500 of the UL subband in some exemplary embodiments of the present disclosure. As shown in Figure 5A, slots 501 to 504 are allocated for DL ​​transmission and slot 505 is allocated for UL transmission, as indicated by the first configuration information. The second configuration instruction indicates the allocation of the frequency domains for the UL-DL split 506 to 508.

[0068] Taking UL-DL split 506 as an example, the second configuration information may indicate the starting position and bandwidth of the corresponding subband 1. For example, the starting PRB may be indicated by the first time index. Furthermore, the bandwidth may be indicated by the number of frequency resources (e.g., PRBs) in the frequency domain. Additionally or alternatively, in some embodiments, the second configuration information may further indicate the starting symbol of the first slot in UL-DL splits 506-508 (i.e., UL-DL split 506), with the rest of UL-DL splits 506-508 being assumed to have complete slot assignments.

[0069] Alternatively, to reduce the number of bits required for the bitmap, a table could be identified or configured for each TDD pattern, showing only the relevant possibilities for using the UL subband active in the time domain. In this way, the gNB can dynamically and flexibly change the SBFD setting in the time domain.

[0070] For example, Table 1 shows the mapping between a 2-bit bitmap and the TDD-UL-DL pattern "DDDSU". It should be understood that this approach is also applicable when multiple TDD-UL-DL patterns are constructed.

[0071] [Table 1]

[0072] Alternatively, in other configuration examples of UL subbands, at least two non-overlapping UL subbands may be configured for SBFD frames, and these subbands may have the same bandwidth and time-domain allocation, e.g., nominal time-domain allocation. One of the UL subbands is separated from the other by a frequency-domain offset. In this case, the second configuration information may indicate the start time resource and start frequency resource of one of the UL subbands (e.g., in the form [first time index, first frequency index]) and the frequency offset. Thus, the position of the other subband can be determined based on the frequency offset.

[0073] Figure 5B shows a schematic diagram of another exemplary configuration 510 of the UL subband in some exemplary embodiments of the present disclosure. As shown in Figure 5B, slots 511 to 514 are allocated for DL ​​transmission, and slot 515 is allocated for UL transmission as indicated by the first configuration information. Two non-overlapping UL subbands 1 and 2, having the same bandwidth and nominal time-domain allocation, are configured for SBFD frames. UL subband 2 is separated from UL subband 1 by a frequency offset, which may be an offset for frequency hopping.

[0074] Furthermore, in some exemplary embodiments, only one of the UL subbands 1 and 2 can be used for each time instance (e.g., slot, symbol, etc.). This is beneficial for UL transmission and DL reception filtering on the UE side. The second device 120 can dynamically indicate which subband is active for UL, and the reference point for frequency domain allocation follows the activated subband.

[0075] Additionally, or alternatively, when frequency hopping is enabled, the two subbands 1 and 2 can be used alternately in the time domain. The start of the frequency hop is on the active subband, which is indicated independently. Furthermore, if two or more UL subbands are configured, the indication of which two of these subbands to use for frequency hopping should also be indicated dynamically or semi-statically.

[0076] In exemplary embodiments, the TDD-UL-DL-Pattern RRC setting element can be extended to include one or more UL subbands applied to the corresponding TDD-UL-DL-Pattern. This allows for the implementation of "asymmetric" SBFD subframe configurations by assigning TDD Pattern 1 and TDD Pattern 2 with different subband configurations, such as DXXXU-DDDXU. Figure 6A is a schematic diagram showing examples of UL subband assignments to TDD-UL-DL patterns in some exemplary embodiments of the present disclosure.

[0077] As shown in Figure 6A, TDD pattern 1 "DDDSU" corresponding to slots 601 to 605 is concatenated to TDD pattern 2 "DDSUU" corresponding to slots 606 to 610. At least one set of UL subbands 1 and 3 may overlap with DL, UL, or flexible symbols in the time domain. DL symbols / slots that overlap with at least one set of UL subbands can be considered SBFD symbols / slots. These can be considered SBFD UL-DL patterns consisting of RRC or upper layers that can be used for the purpose of determining the effectiveness of initial access (e.g., random access channels) and certain semi-static signals, such as the physical downlink control channel (PDCCH) and channel state information reference signal (CSI-RS).

[0078] To enable dynamic adaptation of the SBFD subband configuration, multiple UL subbands may be configured via upper-layer indicators (e.g., RRC signaling), while lower-layer indicators (e.g., MAC CE or a new DCI format) may be used to dynamically activate or deactivate one or more UL subbands. For example, DCI or MAC CE may provide bitmaps, e.g., 10011, to activate or deactivate each of the individual subbands.

[0079] It should be noted that not all UL subbands need to be assigned to the TDD-UL-DL pattern provided by the RRC / SIB, as lower-layer signaling (such as MAC and DCI) may also be used by the UE to determine which UL subbands are enabled or active at some point.

[0080] Figure 6B shows a schematic diagram of an exemplary configuration 610 for dynamic activation or deactivation of a UL subband in some exemplary embodiments of the present disclosure. As shown in Figure 6B, the first device 110 receives configuration messages via lower-layer signaling, such as MAC, DCI, etc., to change the configuration of the UL subband. In the example in Figure 6B, MAC or DCI includes the bitmap "011".

[0081] Therefore, the first device 110 applies the received UL subband settings after a predetermined time has elapsed since receiving the setting message. Consequently, in slots 621-625, subbands 2 and 3 are deactivated and subband 1 is activated, while in slots 626-630, the states of subbands 1-3 are toggled, meaning subbands 2 and 3 are activated and subband 1 is deactivated.

[0082] In some exemplary embodiments, a new MAC CE or DCI format may be used to activate or deactivate each of the individual subbands. For example, DCI or MAC CE provides a bitmap, e.g., 0110, where each bit maps to the corresponding one of four (pre-configured) UL subbands. Optionally, "1" and "0" can be used to indicate which UL subbands are considered enabled and disabled, respectively. Another option is that a value of "1" is used to toggle the activation / deactivation state of the corresponding subband, in other words, to switch the subband state from enabled to disabled, or from disabled to enabled.

[0083] It should be understood that other options are possible for implementing the embodiments, including a mixture of upper-layer and lower-layer signaling. For example, a table with multiple possible enabled or disabled states, e.g., 0101, 0111, 0000, 1010, may be provided through RRC signaling, and a 2-bit indication in DCI or MAC CE may point to one of four entries in the table. Thus, the disclosure is not limited in this respect.

[0084] In some exemplary embodiments, an approach similar to that used to dynamically signal SFI using DCI format 2_0 in dynamic TDD may be reused for SBFD operation. In this case, the frequency domain allocation of the DU split is set via higher-layer signaling (e.g., RRC, MAC, etc.). The time granularity for instructing SBFD operation can be OFDM symbol level. One or more tables of slot formats are configured in the first device 110, showing multiple options for UL-DL resource partitioning with a time resolution of one OFDM symbol. For example, a table similar to Table 11.1.1-1 of TS 38.213 in this embodiment may be used for this purpose, where the "F" symbol is replaced with the "SBFD" symbol.

[0085] Instead of using a new table, a subset of unused indices 66–254 from Table 11.1.1-1 of TS 38.213 can be used for signaling SBFD symbols. For example, indices 60–115 can be used to signal the same slot format as indices 0–55, but the "F" symbol can be replaced with the "SBFD" symbol. In some embodiments, the gNB can transmit one DCI 2_0 per cell. UEs that do not support SBFD operation interpret the "F" symbol as a flexible symbol according to Table 11.1.1-1 of TS 38.213, while SBFD-enabled UEs interpret the "F" symbol as an SBFD symbol with a frequency domain UL-DL split configured in the upper layer. Furthermore, in some cases, SBFD-enabled UEs can further configure, through upper-layer signaling, whether the "F" symbol is interpreted as a flexible symbol or an SBFD symbol according to Table 11.1.1-1 of TS 38.213.

[0086] Alternatively, in some other embodiments, the gNB can configure non-SBFD-supporting and SBFD-enabled UEs via two separate DCI 2_0. In this case, the SFI signals separately to the non-SBFD-supporting and SBFD-enabled UEs. The index either points to two different tables, namely Table 11.1.1-1 of TS 38.213 for non-SBFD-supporting UEs and a new table for SBFD-enabled UEs, or points to the same extended table 11.1.1-1 of TS 38.213.

[0087] Table 2 shows examples of slot formats available for SBFD operation. For example, one entry can be defined as D, X2, X2, X2, U, U, X3, X3, X3, X3, X3, U, U, U, where "Xn" represents the UL-DL split SBFD symbol in the frequency domain set by SBFD_UL_subband_n.

[0088] [Table 2]

[0089] It should be understood that some of the steps in process 200 are optional or omittable, and the order of the steps is given for illustrative purposes only. Therefore, embodiments of this disclosure are not limited in this respect.

[0090] Exemplary embodiments of this disclosure provide solutions for SBFD frame structures and associated configurations. The configuration of UL-DL splits and UL subbands is flexible; that is, the location and size of UL-DL PRB splits may be configured, for example, at the cell level or operator level, or may change over time in individual cells. For this purpose, one or more signalings are activated by gNB to set, activate, or deactivate UL-DL PRB splits. Furthermore, asymmetric SBFD subframe configurations are also possible by assigning TDD patterns 1 and 2 with different subband configurations.

[0091] Figure 7 shows a flowchart of an exemplary method 700 in some exemplary embodiments of the present disclosure. Method 700 can be implemented in a terminal device, for example, the first device 110 described with reference to Figure 1. For illustrative purposes, Method 700 will be described with reference to Figure 1.

[0092] In 710, the first device 110 receives first configuration information from the second device 120, which indicates a set of resources for time-division or frequency-division duplexing between the first device 110 and the second device 120. The set of resources may include a first subset of resources for uplink transmission.

[0093] In 720, the first device 110 receives second configuration information from the second device 120 indicating at least one second subset of resources for uplink transmission. The at least one second subset of resources may include at least one resource other than the first subset of resources.

[0094] In some exemplary embodiments, a first subset of resources may not overlap with at least one second subset of resources. Additionally, or alternatively, at least a portion of the first subset of resources may overlap with at least one second subset of resources.

[0100] In some exemplary embodiments, the first device 110 may determine a third subset of resources, including first and second subsets of resources, based on first and second configuration information. The first device 110 can then send data transmissions to the second device 120 using the third subset of resources.

[0101] In some exemplary embodiments, the second configuration information may indicate at least one second subset of resources in the frequency domain. The first device 110 may receive a configuration message from the second device 120 indicating at least one second subset of resources in the time domain.

In this case, the first value of a bit in the bitmap may indicate the corresponding slot or symbol to which the uplink subband corresponds to one of at least one second subset of the resource. Additionally, or alternatively, the second value of a bit in the bitmap may indicate the corresponding slot or symbol to which the uplink subband does not apply.

[0105] In some exemplary embodiments, multiple values ​​of a bitmap apply an uplink subband. Multiple downlink slots or symbols in a time-division duplex pattern, or At least one special slot or symbol in a time-division duplex pattern, You may show at least one combination of these. In this case, the mapping between multiple values ​​and multiple combinations may be pre-configured or predetermined in the first device 110 and the second device 120.

[0106] In some exemplary embodiments, the start time resource of the second subset of resources may be the first symbol of the corresponding slot indicated by the bitmap.

[0107] In some exemplary embodiments, the first start time resource of the second subset may be represented by the second device 120. Furthermore, the remaining start time resources of the second subset may be the first symbols of the corresponding slots represented by bitmaps.

[0108] In some exemplary embodiments, the second configuration information may indicate a first target subset and frequency offset of the resource in the time domain. Based on the first target subset and frequency offset of the resource in the time domain, the first device 110 may determine at least one second target subset of the resource. In this case, the first target subset of the resource may correspond to a first uplink subband. Additionally, or alternatively, at least one second target subset of the resource may correspond to at least one second uplink subband.

[0110] In some exemplary embodiments, the first configuration information may indicate a first time-division duplex pattern and a second time-division duplex pattern of the first device 110. Additionally or alternatively, the second configuration message may include at least one first uplink subband assigned to the first time-division duplex pattern and at least one second uplink subband assigned to the second time-division duplex pattern.

[0111] In some exemplary embodiments, the second configuration information may indicate at least one second subset of resources in the frequency domain.

The first device 110 may determine a third subset of resources allocated for uplink transmission based on a slot format indicator. In this case, the third subset of resources may include the first subset of resources and at least one second subset of resources. Thus, the first device can transmit data transmissions to the second device 120 using the third subset of resources.

[0112] In some exemplary embodiments, the first device 110 may receive a configuration message from the second device 120. If the configuration message includes a first instruction that activates at least a first portion of at least one second subset of the resources, the first device 110 may, based on the first instruction, determine a third subset of the resources allocated for uplink transmissions.

The first device 110 can then send a data transmission to the second device 120 using the third subset of resources.

[0113] In some exemplary embodiments, if the configuration message includes a second instruction to deactivate at least a second portion of at least one second subset of the resources, the first device 110 may determine a fourth subset of the resources allocated for uplink transmission based on the second instruction. The fourth subset of resources may include the first subset of resources and the remaining portion of at least one second subset of the resources other than at least a second portion.

[0125] In some exemplary embodiments, the second device 120 can receive data transmissions from the first device 110 in a third subset of resources, which includes first and second subsets of resources.

[0126] In some exemplary embodiments, the second configuration information may indicate at least one second subset of resources in the frequency domain. The second device 120 may send a configuration message to the first device 110 indicating at least one second subset of resources in the time domain.

In this case, the first value of a bit in the bitmap may indicate the corresponding slot or symbol to which the uplink subband corresponds to one of at least one second subset of the resource. Additionally, or alternatively, the second value of a bit in the bitmap may indicate the corresponding slot or symbol to which the uplink subband does not apply.

The first target subset of the resource may correspond to a first uplink subband, and at least one second target subset of the resource may correspond to at least one second uplink subband.

[0134] In some exemplary embodiments, the frequency offset may correspond to frequency hopping associated with the first device 110. The first uplink subband and at least one second uplink subband may be applied alternatively in the time domain.

[0136] In some exemplary embodiments, the second configuration information may represent at least one second subset of resources in the frequency domain. In this case, the second device 120 can transmit a DCI to the first device 110 that includes an SFI corresponding to at least one second subset of resources in the time domain. Thus, the second device 120 can receive data transmissions from the first device 110 in a third subset of resources that includes a first subset of resources and at least one second subset of resources.

[0137] In some exemplary embodiments, the second device 120 may send a setup message to the first device 110 that includes a first instruction to activate at least a first portion of at least one second subset of the resource.
