Description

BACKGROUND

[0002] Currently, New Radio (NR) supports two duplex modes: frequency division duplex (FDD) for paired bands and time division duplex (TDD) for unpaired bands. In TDD, time domain resources are divided between downlink (DL) and uplink (UL). Allocating a limited duration for uplink in TDD will result in reduced coverage, increased latency, and reduced capacity.

Sub-band non-overlapping full duplex (SBFD) has been proposed as a scheme to enhance duplex operation. In SBFD, DL transmission and UL reception are allowed simultaneously on different physical resource blocks (PRBs) within an unpaired wideband NR cell.

[0029] As used herein, the terms “symbol combination” and “temporal location of CSI-RS resource in a time slot” are used interchangeably.

[0030] As mentioned above, SBFD technology has been proposed as a solution to enhance full-duplex operation. Furthermore, to further improve resource scheduling flexibility, in some cases, SBFD time slots may include both SBFD symbols and non-SBFD symbols, leading to greater complexity in resource scheduling. Therefore, it is necessary to discuss how to reduce implementation complexity while ensuring compatibility with traditional TDD DL / UL configurations.

[0031] In wireless communication systems, CSI RS communication is crucial for both terminal and network devices. Generally, resources used for transmitting CSI RS are scheduled by the network device. In some embodiments, for an SBFD-aware UE, frequency resource allocation for CSI RS can span downlink subbands. Furthermore, in one implementation, two consecutive CSI-RS resources connected together can be allocated for CSI RS transmission. In another implementation, one CSI-RS resource can be allocated for CSI RS transmission. Additionally, CSI-RS resources can be non-contiguous CSI-RS resource allocations, or contiguous CSI-RS resource allocations with non-contiguous CSI-RS resources derived by excluding frequency resources outside of the DL subband(s).

[0032] In NR, CSI-RS is used for several different purposes, one of which is to track the frequency and time of the received DL signal.

[0033] In some embodiments, for configuration with high-level parameters trs-Info of NZP-CSI-RS-ResourceSet Terminal devices should assume NZP-CSI-RS-ResourceSet The antenna ports with the same port index in the configured NZP CSI-RS resources are identical.

[0034] In some embodiments, for frequency range 1, the terminal device may be configured with one or more NZP CSI-RS sets, wherein NZP-CSI-RS-ResourceSet It consists of four periodic NZP CSI-RS resources in two consecutive time slots, with each time slot containing two periodic NZP CSI-RS resources. If there are no two consecutive time slots... tdd-UL- DL-ConfigurationCommon or tdd-UL-DL-ConfigDedicated If the indication is DL timeslot, then the terminal device can be configured with one or more NZP CSI-RS sets, where NZP-CSI-RS-ResourceSet It consists of two periodic NZP CSI-RS resources in one time slot.

[0035] In the case of CSI RS used to track RS, each CSI-RS resource can be defined by some high-level parameters with certain limitations. NZP-CSI-RS-Resource Configuration. One limitation is that the time domain locations of two CSI-RS resources should be in one time slot, or the time domain locations of four CSI-RS resources should be in two consecutive time slots (and be identical in the two consecutive time slots).

[0036] The temporal location of the two CSI-RS resources is determined by higher-level parameters. CSI-RS-resourceMapping The definition is given by one of {4, 8}, {5, 9}, {6, 10} for frequency range 1 (FR1) and frequency range 2 (FR2), and {0, 4}, {1, 5}, {2, 6}, {3, 7}, {7, 11}, {8, 12}, or {9, 13} for FR2. Another limitation is given by... CSI-RS-ResourceMapping High-level configuration parameters freqBand The bandwidth of the given CSI-RS resources is 52 and The minimum value in the resource block, or equal to Resource block.

[0037] An example of a static TDD frame structure in a cell bandwidth is shown below, for example, DDDSU, where D, S, and U refer to the DL slot, special slot, and UL slot, respectively. The special slot may contain DL, UL, and gap symbols.

[0038] Example of a static TDD frame structure in a cell bandwidth

[0039] An example of the SBFD frame structure in a cell bandwidth is shown below, for example, a DUD with the conventional frame structure DDDSU.

[0040] Example of SBFD frame structure in a cell bandwidth

[0041] As mentioned above, in the case of FR1, TRS measurement requires two consecutive "D" time slots. Conventional static TDD frames (such as DDDSU shown above) typically have more than two consecutive "D" time slots, which can satisfy the requirement of transmitting CSI-RS for TRS in two consecutive DL time slots and the configuration of CSI-RS for time-frequency tracking of users in the cell at full bandwidth.

[0042] However, in the case of SBFD networks, each time slot can be configured with both UL and DL, and UL can be in the middle of the band, which disrupts the continuity of the DL RB. Simultaneously, the configuration of the CSI-RS for TRS on a specific symbol may conflict with the UL RB. In this situation, if the CSI-RS for TRS is configured on the DL RB of an SBFD time slot, conventional measurements can be performed on that CSI-RS used for tracking resources by either a traditional UE or an SBFD DL UE, but the SBFD UL UE cannot detect the TRS, resulting in degraded communication performance for the SBFD UL UE.

[0043] In addition to TRS transmissions, other regular and public communications may also be affected due to the support for SBFD time slots that include at least one SBFD symbol and at least one non-SBFD symbol.

[0044] In light of the above discussion, it is desirable to propose a more flexible solution for the transmission format indicator for SBFD time slots.

[0045] According to this disclosure, a first device (such as a terminal device) receives configuration information from a second device, wherein the configuration information includes a transmission format indicator. Specifically, the transmission format indicator is applied to a subband or subband group and is applied to multiple sub-resources in the time domain included in an SBFD time slot, wherein the multiple sub-resources are multiple symbols including at least one SBFD symbol and at least one non-SBFD symbol. The first device then performs communication with the second device on the multiple sub-resources, at least in part based on the configuration information.

[0046] A subband or subband group can be understood as a frequency band of the carrier or (multiple) subbands of a frequency band configured for SBFD time slots.

[0047] Traditional solutions only support configuring the transmission format indicator for the total frequency band, which sometimes causes certain routine and common communications (such as measurement TRS) to fail at the SBFD UE. According to this disclosure, the transmission format indicator will be applied to a sub-band or sub-band group, and will be applied to multiple sub-resources in the time domain included in the SBFD timeslot. In this way, scheduling flexibility is improved, and the SBFD UE can well support routine and common communications.

[0048] Example Environment FIG. 1A An example communication environment 100A in which exemplary embodiments of the present disclosure can be implemented is shown. Communication environment 100A includes a first device 110 and a second device 120. The service area provided by the second device 120 is referred to as a cell. Furthermore, the second device 120 can provide one or more cells; for example, cell 102 is provided by the second device 120, such as... FIG. 1A As shown.

[0049] In some example embodiments, the first device 110 may be included in the terminal device / apparatus, and the second device 120 may be included in the network device / apparatus serving the terminal device / apparatus.

[0050] In the following description, for illustrative purposes, some exemplary embodiments are depicted in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some exemplary embodiments, the operations described in connection with the terminal device can be implemented at the network device or other devices, and the operations described in connection with the network device can be implemented at the terminal device or other devices.

[0051] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a network device, the link from the second device 120 to the first device 110 is referred to as a downlink (DL), and the link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmitting (TX) device (or transmitter), and the first device 110 is a receiving (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0052] Communication in the communication environment 110A can be implemented according to any suitable communication protocol(s), including but not limited to cellular communication protocols such as first-generation (1G), second-generation (2G), third-generation (3G), fourth-generation (4G), fifth-generation (5G), and sixth-generation (6G), wireless local area network communication protocols such as IEEE 802.11, and / or any other currently known or future-developed protocols. Furthermore, communication can utilize any suitable wireless communication technology, including but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiple Access (OFDM), Discrete Fourier Transform Extended OFDM (DFT-s-OFDM), and / or any other currently known or future-developed technologies.

[0053] The 100A communication environment supports multiple duplex modes. (See reference below.) FIG. 1B Box 100B shows three example duplex modes (i.e., TDD, FDD, and SBFD).

[0054] FDD can be used in paired frequency bands, while TDD can be used in unpaired frequency bands. In TDD, time-domain resources are divided between DL and UL. Allocating a limited duration for UL in TDD will result in reduced coverage, increased latency, and reduced capacity. SBFD can be considered an evolution of duplex operation in NR. Specifically, SBFD allows simultaneous DL and UL transmissions on different Physical Resource Blocks (PRBs) / subbands within an unpaired broadband NR cell, such as... FIG. 1B As shown.

[0055] In some embodiments, an SBFD time slot may include both SBFD symbols and non-SBFD symbols.

[0056] Furthermore, different duplex modes can be used interactively. Therefore, there may be two resource types for DL ​​and UL transmissions: SBFD resources (such as time slots) containing non-overlapping DL subbands and (multiple) UL subbands, and Non-SBFD resources (such as time slots) where the entire frequency band is used for DL ​​or UL (i.e., full DL / UL time slots).

[0057] For better understanding, please refer to the following: FIG. 1C It shows block 100C of SBFD resources and non-BFD resources.

[0058] For further understanding, please refer to the following: FIG. 1D through FIG. 1I It shows some time slot combinations from 100D to 100I. FIG. 1D through FIG. 1I There are many time slot combinations that have both SBFD symbols and non-SBFD symbols.

[0059] It should be understood that the System Synchronization Block (SSB), System Information Block (SIB), Paging Message, Common Message, TRS, Physical Downlink Control Channel (PDCCH), and Physical DL Shared Channel (PDSCH) are shown as... FIG. 1D through FIG. 1I The example DL transmission marked in the middle uses the Sounding Reference Signal (SRS), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), and Physical Random Access Channel (PRACH) as its components. FIG. 1D through FIG. 1IExamples of UL transmissions marked in the diagram are given for illustrative purposes only. In other words, resources configured for UL can be used to send any and all suitable types of UL transmissions, and resources configured for DL ​​can be used to send any and all suitable types of DL transmissions. This disclosure is not limited thereto.

[0060] In some embodiments, the operating mode having at least the time and frequency positions of the sub-bands for SBFD operation may be known to the SBFD-aware UE. That is, the SBFD time slots should be known to the (SBFD-aware) UE.

[0061] Operation and Example Signaling for Communication As discussed, some routine and common communications may also be affected when both SBFD resources (such as SBFD slots / symbols) and non-SBFD resources (such as non-SBFD slots / symbols) are supported. For example, if the conventional configuration of CSI-RS for tracking for FR1 is applied, i.e., two or four CSI-RS resources in two consecutive slots (which are identical in both consecutive slots), then the SBFD-aware UE may face problems measuring / receiving CSI-RS for TRS.

[0062] According to some example embodiments of this disclosure, a solution for a transport format indicator for SBFD is provided. The example embodiments discussed below enhance scheduling flexibility, and regular and common communications can be well supported by the SBFD UE.

[0063] refer to FIG. 2 This illustrates a signaling flow 200 of communication according to some embodiments of the present disclosure. For purposes of discussion, reference will be made, for example, by using the first device 110 and the second device 120. FIG. 1A through FIG. 1I Discuss signaling flow 200.

[0064] It should be understood that the operation of the first device 110 and the second device 120 should be coordinated. In other words, the second device 120 and the first device 110 should have a common understanding regarding configuration, parameters, etc. Such a common understanding can be achieved through any suitable interaction between the second device 120 and the first device 110 or by both the second device 120 and the first device 110 applying the same rules / policies.

[0065] In the following description, although some operations are presented from the perspective of the first device 110, it should be understood that the corresponding operations should be performed by the second device 120. Similarly, although some operations are presented from the perspective of the second device 120, it should be understood that the corresponding operations should be performed by the first device 110. For the sake of brevity, some identical or similar content has been omitted here.

[0066] Additionally, in the following description, examples of message types (such as "RRC message" or "DCI") are for illustrative purposes only and do not imply any limitation. In other example embodiments, any suitable message type may be used for interaction between the first device 110 and the second device 120.

[0067] exist FIG. 2 In the example, the first device 110 is a terminal device, and the second device 120 is a network device.

[0068] In operation, the first device 110 receives configuration information 220 from the second device 120, wherein the configuration information includes a transmission format indicator. Specifically, the transmission format indicator will be applied to a subband or subband group, and will be applied to multiple sub-resources in the time domain included in the SBFD time slot, wherein the multiple sub-resources are multiple symbols that make up at least one SBFD symbol and at least one non-SBFD symbol.

[0069] Then, the first device 110 performs communication 230 with the second device 120 on SBFD time slots (i.e., multiple sub-resources) based at least in part on configuration information.

[0070] In summary, unlike conventional schemes where the transmission format indicator is configured for the total frequency band, according to this disclosure, the transmission format indicator will be applied to sub-bands or sub-band groups, and will be applied to multiple sub-resources in the time domain included in the SBFD time slots. In this way, scheduling flexibility is improved, and regular and common communications can be well supported by the SBFD UE.

[0071] Further details regarding the transfer format indicator will be discussed below.

[0072] In some example embodiments, the transport format indicator is a sub-band slot format indicator (SFI) for SBFD slots.

[0073] In some example embodiments, the transport format indicator may indicate that the first portion of a plurality of sub-resources is used for UL transport. Alternatively, in some example embodiments, the transport format indicator may indicate that the last portion of a plurality of sub-resources is used for DL ​​transport.

[0074] In this way, the UL symbol provides a longer UL duration for UL coverage and data transmission, while the DL symbol at the end of the time slot can be used for rapid scheduling of subsequent time slots, especially for subsequent UL transmissions in subsequent time slots, so as to reduce the delay of UL scheduling.

[0075] Alternatively, in some example embodiments, the transport format indicator may indicate that the last portion of a plurality of sub-resources is used for UL transport. Alternatively, in some example embodiments, the transport format indicator may indicate that the first portion of a plurality of sub-resources is used for DL ​​transport.

[0076] Table 1 below shows some examples of transmission formats, where D, F, and U refer to DL symbol, flexible symbol, and UL symbol, respectively.

[0077] Table 1 Examples of transmission formats

[0078] For better understanding, please refer to the following: FIG. 3 It shows an example time slot combination 300.

[0079] exist FIG. 3 In this context, there are some time slots consisting of both SBFD symbols and non-SBFD symbols (such as time slot #0). As for time slot #0, it can be configured with format #4 (i.e., {DDDDDDDFUUUUUU}), where format #4 will only be applied to the subband containing UL transmissions (hereinafter also referred to as the SBFD subband).

[0080] As an example embodiment, using the aforementioned transmission format indicator, the first device 110 can first perform UL transmission and then operate in DL reception mode. For example, it can first perform one or more UL symbols and then perform one or more DL symbols. Furthermore, 0 / 1 / 2N symbols (i.e., F symbols) can exist between UL and DL symbols to handle the switching from UL to DL.

[0081] In some example embodiments, if the SBFD timeslot is the first of a plurality of timeslots, the format indicator may indicate that the last portion of the plurality of sub-resources is used for UL transmission. In some example embodiments, if the SBFD timeslot is the last of a plurality of timeslots, the format indicator indicates that the first portion of the plurality of sub-resources is used for UL transmission.

[0082] As an example embodiment, in the case of multiple time slots, the above-described transmission format indicator can be provided together with other conventional time slot formats. For example, there is a continuous UL symbol duration, including several symbols (e.g., 6 symbols in time slot #0), then several time slots (e.g., time slots #1, #2, #3), and then several symbols (6 symbols in time slot #4), which provides a continuous UL duration for more than one time slot. In this case, time slot #0 can be configured with format #0, and time slot #4 can be configured with format #2. The additional time slots #1, #2, and #3 can be configured as ULSBFD time slots.

[0083] In this specific embodiment, the last time slot is configured with format #2, which provides more opportunities for DL ​​transmission in the last few symbols of the PDCCH, and the first device can obtain continuous UL scheduling.

[0084] In some example embodiments, the SBFD slot can be periodic or aperiodic (i.e., part of a periodic or aperiodic resource). For better understanding, refer now to FIG. 4A It shows an example time slot combination 400A. FIG. 4A In this context, there exist some periodic or aperiodic special configuration time slots with both SBFD and non-SBFD symbols. For example, time slots #1 and #2 are not normal periodic time slots. Furthermore, time slots #1 and #2 have both SBFD and non-SBFD symbols. In this case, time slot #1 can be configured with format #1, and time slot #2 can be configured with format #4. These two time slots can be periodic (or aperiodic).

[0085] In some example embodiments, the configuration information may also indicate the NZP CSI RS configuration for TRS, so that UL transmission and TRS transmission can be performed by the UE within a single time slot. Furthermore, the requirements for two consecutive "D" time slots for FR1 TRS and consecutive "U" time slots for UL coverage enhancement can be met.

[0086] In summary, by utilizing the CSI-RS configuration for TRS and the aforementioned transmission format indicators, the SBFD UE can support a more flexible configuration of the CSI-RS for TRS (typically a reference signal), which has two separate symbol positions in addition to the UL symbols (or symbols with SBFD UL subbands) in two consecutive time slots. Simultaneously, the SBFD UE can perform UL services while simultaneously listening to TRS within a single SBFD time slot.

[0087] Still referencing FIG. 2 In some example embodiments, when performing communication with the second device, the first device 110 sends a 232 UL transmission to the second device 120 based on the transmission format indicator and the NZP CSI RS configuration for tracking RS. Additionally, the first device 110 receives a 234 NZPCSI RS for tracking RS from the second device 120 based on the NZP CSI RS configuration for tracking RS. Some details are discussed below.

[0088] In some example embodiments, in addition to the transport format indicator, the configuration information also includes NZP CSIRS configuration for TRS for two consecutive time slots, including an SBFD time slot and another time slot (which may be an SBFD time slot or a non-SBFD time slot).

[0089] In some example embodiments, the NZP CSI RS configuration and transport format indicator for TRS are included in the same message or at least two different messages.

[0090] As an example embodiment, the first device 110 may first receive configuration information including a transmission format indicator (e.g., via RRC signaling), and then receive configuration information including NZP CSI RS configuration for TRS (e.g., via another RRC signaling or DCI).

[0091] Alternatively, in another example embodiment, the first device 110 may (e.g., via an RRC signaling) receive configuration information including both a transport format indicator and an NZP CSI RS configuration for TRS.

[0092] In some example embodiments, the two consecutive time slots are periodic or aperiodic time slots.

[0093] In some example embodiments, the NZP CSI RS configuration for TRS may indicate the same combination of symbols corresponding to two consecutive time slots, wherein the combination of symbols indicates the resources (i.e., time-domain locations) used to transmit NZP CSI RS for TRS.

[0094] Alternatively, in some example embodiments, the NZP CSI RS configuration for TRS may indicate two different symbol combinations corresponding to the SBFD time slot and another time slot, respectively, wherein the symbol combination indicates the resources (i.e., time-domain locations) used to transmit the NZP CSI RS for tracking RS.

[0095] In summary, in some example embodiments, the time-domain location (i.e., symbol combination) of two CSI-RS resources in a time slot or the time-domain location of four CSI-RS resources in two consecutive time slots may be the same or different in the two consecutive time slots.

[0096] Furthermore, in some example embodiments, the temporal location (i.e., symbol combination) can be determined by higher-level parameters. CSI-RS- resourceMapping To define.

[0097] For better understanding, please refer to the following: FIG. 4A .exist FIG. 4A In this context, TRS can be received on different sets of symbols (i.e., different combinations of symbols) in consecutive time slots.

[0099] Alternatively, the first device 110 can measure the TRS in time slots #0 and #1 aperiodically. In some example embodiments, the aperiodic TRS measurement can be triggered by the second device 120. Specifically, the second device 120 can instruct the first device 110 to measure the TRS, and instruct the TRS to be placed in symbols {2, 6} in time slot #0 and in symbols {7, 11} in time slot #1.

[0100] Now for reference FIG. 4B It shows an example time slot combination 400B. FIG. 4B In this context, TRS can be received on the same set of symbols (i.e., the same combination of symbols) in two consecutive time slots.

[0101] In some example embodiments, the first device 110 periodically measures the TRS in time slot #0 and time slot #1, wherein the TRS is placed in the symbols {2, 6} in time slot #0 and time slot #1.

[0102] Alternatively, in some example embodiments, the first device 110 may non-periodically measure the TRS in time slots #0 and #1, wherein the TRS is placed in symbols {2, 6} in time slots #0 and #1. In some example embodiments, the non-periodic TRS measurement may be triggered by a second device 120. Specifically, the second device 120 may instruct the first device 110 to measure the TRS and instruct that the TRS is placed in symbols {2, 6} in time slots #0 and #1.

[0103] In some example embodiments, in the case of FR1, the symbol combination is one of the following: {0, 4}, {1, 5}, {2, 6}, {3, 7}, {4, 8}, {5, 9}, {6, 10}, {7, 11}, {8, 12}, or {9, 13}.

[0104] In some example embodiments, in the case of FR2, the symbol combination is one of the following: {0, 4}, {1, 5}, {2, 6}, {3, 7}, {4, 8}, {5, 9}, {6, 10}, {7, 11}, {8, 12}, or {9, 13}.

[0105] Optionally, in some example embodiments, the configuration information may indicate SBFD-related information to the first device 110. As an example embodiment, the configuration information may indicate at least one of the following: frequency band; Multiple time slots / symbols, wherein the frequency band is divided into multiple sub-bands, and at least one of the sub-bands is used for DL ​​transmission, and at least one of the sub-bands is used for UL transmission, i.e. SBFD time slots / symbols, and the positions of the multiple time slots / symbols in the radio frame; Multiple time slots / symbols, where the entire frequency band is used for DL ​​or UL transmission, i.e., non-SBFD time slots / symbols, and the location of multiple time slots / symbols within a radio frame; or Common TDD frame structure configurations, such as DDDSU (Mode 1).

[0106] An example of configuration information indicating SBFD-related information is shown below.

[0107]

[0108] It should be understood that, depending on the specific scenario, the configuration information may include other parameters. This disclosure is not limited thereto.

[0109] Furthermore, in some example embodiments, SBFD support can be implemented as a configurable / optional feature. Still refer to FIG. 2 The first device 110 can enable the 210 SBFD mode by itself or by the second device 120.

[0110] Based on the above process, by introducing a transmission format indicator that can be applied to subbands (or subband groups), scheduling flexibility is enhanced, and regular and common communications can be well supported by the SBFD UE. In particular, the newly introduced transmission format indicator enables a more flexible SBFD structure, which is especially beneficial for CSI-RS used for TRS in the case of FR1.
