Method and apparatus for coordination between synchronization signal block measurement and sub-band full duplex operation

Abstract

Various solutions for coordinating Synchronization Signal Block (SSB) measurements with Subband Full-Duplex (SBFD) operation are described. An apparatus can receive a first configuration and a second configuration from a network node. The first configuration includes timing information for the SBFD uplink (UL) subband. The second configuration includes timing information for multiple SSB timings. Based on the first and second configurations, the apparatus can determine that the SSB timings overlap with symbols or time slots of the SBFD UL subband in time. Subsequently, the apparatus can either prioritize SSB measurements on the SSB timings rather than UL transmissions on the symbols or time slots of the SBFD UL subband, or prioritize UL transmissions on the symbols or time slots of the SBFD UL subband rather than SSB measurements on the SSB timings.

[0002] This disclosure is part of a non-provisional application claiming priority to U.S. Patent Application No. 63 / 553,658, filed February 15, 2024, and U.S. Patent Application No. 63 / 670,200, filed July 12, 2024, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure generally relates to mobile communications, and more specifically, to the coordination between synchronization signal block (SSB) measurement and sub-band full-duplex (SBFD) operation. Background Technology

[0004] Unless otherwise stated herein, the methods described in this section are not prior art to the claims and are not recognized as prior art solely because they are included in this section.

[0005] Time division duplexing (TDD) is a channel access technology widely used in mobile communication systems, such as fourth-generation (4G) Long Term Evolution (LTE) and fifth-generation (5G) New Radio (NR) systems. This technology is based on half-duplex channel access, where within a time slot, the entire component carrier (CC) bandwidth is used for either downlink (DL) or uplink (UL), but not both simultaneously. Among the various TDD modes supported by 5G NR (defining different DL / UL ratios), a fixed downlink-dominant TDD mode (e.g., DDDSU) is generally preferred in most deployments. In downlink-dominant TDD modes, the limited time duration allocated to UL leads to reduced UL coverage and increased latency. As an enhancement, in the 3rd Generation Partnership Project (3GPP)... rd In Generation Partnership Project (3GPP) Release 18, the simultaneous existence of DL and UL transmissions on the user equipment (UE) side or base station (BS) side within the conventional TDD frequency band was introduced, or more specifically, Subband Full-Duplex (SBFD) operation was introduced.

[0006] In typical mobile communication systems, various time slot types may exist, including downlink-only slots (DL-only slots, also known as DL slots), uplink-only slots (UL-only slots, also known as UL slots), flexible slots, and special slots. Flexible slots are those initially not configured with a specific transmission direction but can later be reconfigured as DL or UL slots. Special slots are those where some symbols are configured as flexible symbols, while others are configured as DL or UL symbols. SBFD typically introduces simultaneous UL transmissions within portions / partitions of the channel bandwidth (CBW) in DL slots under TDD mode. These symbols / slots where UL transmissions coexist with DL reception can also be called SBFD symbols / slots. However, supporting SBFD operation may present some challenges under the current 5G NR TDD framework. For example, there are situations where the timing of the Synchronization Signal Block (SSB) overlaps with SBFD symbols / slots. In such cases, some UEs (e.g., half-duplex UEs) may not be able to simultaneously perform UL transmissions and SSB measurements. Furthermore, for SBFD operations, UL transmission may negatively impact SSB measurements due to cross-link interference (CLI).

[0007] Therefore, appropriate solutions are needed to address these issues. Summary of the Invention

[0026] Detailed embodiments and implementations of the claimed subject matter are disclosed herein. However, it should be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matter, which may be implemented in various forms. This disclosure may take many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided to make the description of this disclosure exhaustive and complete, and to fully communicate the scope of this disclosure to those skilled in the art. In the following description, well-known features and technical details may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0027] Overview

[0028] According to embodiments of this disclosure, various techniques, methods, approaches, and / or solutions related to SSB measurement and SBFD operational coordination are involved. Several possible solutions can be implemented separately or in combination according to this disclosure. That is, although these possible solutions are described separately below, two or more of them can be implemented in different combinations.

[0029] In 5G NR, the frequency resources of the DL (Deep Stream) time slot are used solely for DL ​​(Deep Stream) transmission, while the frequency resources of the UL (Ultra Stream) time slot are used solely for UL (Ultra Stream) transmission. Within the SBFD (Single-Slot Difference) time slot, the frequency resources of that time slot are used for both DL and UL transmission. More specifically, within the SBFD time slot, the DL and UL subbands are separated by a fixed number of resource blocks (RBs), which are called guard bands (GBs) and are not used for any DL / UL data transmission. Figure 1 Two example scenarios, 110 and 120, are shown to configure SBFD time slots under the current 5G NR TDD framework. Scenario 110 describes a TDD mode including one DL time slot (denoted by D), one or more SBFD time slots (denoted by X), and one UL time slot (denoted by U), where the SBFD time slot is configured as a DUD frame structure, the CBW is divided into three subbands, and the UL signal is transmitted in the middle subband. Scenario 120 describes another TDD mode including one DL time slot (denoted by D), one or more SBFD time slots (denoted by X), and one UL time slot (denoted by U), where the SBFD time slot is configured as a DU frame structure, the CBW is divided into two subbands, and the UL signal is transmitted in the bottom subband.

[0030] However, as mentioned earlier, there may be some issues in supporting SBFD operation and SSB measurement. Figure 2 Two example scenarios, 210 and 220, demonstrate the coexistence of SSB and SBFD configurations under the current 5G NR TDD framework. Scenario 210 describes the SBFD configuration indication "DXXXU" TDD mode, with the SSB configuration indicating four SSB candidates on two time slots for operation in a sub-3GHz bandwidth (BW) with a sub-carrier spacing (SCS) of 15 kHz and an SSB-periodicity of 20 ms. Each SSB burst occurs in one of three "X" time slots. The timing and frequency position of the SSB candidate occurrence can be referred to as the SSB timing. Scenario 220 describes the SBFD configuration indication "DXXXU" TDD mode, with the SSB configuration indicating four SSB candidates on two time slots for operation in a 3GHz to 6GHz bandwidth with an SCS of 30 kHz and an SSB-periodicity of 20 ms. Each SSB burst occurs in one of six "X" time slots. Figure 3Two example scenarios, 310 and 320, demonstrate the coexistence of SSB and SBFD configurations under the current 5G NR TDD framework. Scenario 310 describes an SBFD configuration indicating "DXXXU" TDD mode, with an SSB configuration indicating eight SSB candidates across four time slots for operation in sub-3GHz bandwidth with an SCS of 15kHz and ssb-periodicity = 20ms, where each SSB burst occurs in three out of three "X" time slots. Scenario 320 describes an SBFD configuration indicating "DXXXU" TDD mode, with an SSB configuration indicating eight SSB candidates across four time slots for operation in 3GHz to 6GHz bandwidth with an SCS of 30kHz and ssb-periodicity = 20ms, where each SSB burst occurs in three out of six "X" time slots.

[0031] In view of the above, this disclosure proposes several schemes related to SSB measurement and SBFD operation coordination. According to some schemes proposed in this disclosure, when the SSB timing overlaps with the SBFD symbol / slot in time, the UE may prioritize SSB measurement on the SSB timing rather than performing UL transmission on the SBFD symbol / slot (e.g., configured UL transmission and / or dynamically scheduled UL transmission). Furthermore, according to some schemes proposed in this disclosure, when the SSB timing overlaps with the SBFD symbol / slot in time, the UE may allow UL transmission on the SBFD symbol / slot (e.g., configured UL transmission and / or dynamically scheduled UL transmission). For example, the UE may prioritize UL transmission on the SBFD symbol / slot rather than performing SSB measurement on the SSB timing. Further, according to some schemes proposed in this disclosure, when the SSB timing overlaps with the SBFD symbol / slot in time, the UE may allow the occurrence of SSB on the SBFD symbol / slot to cover the symbol / slot allocation of the SBFD symbol / slot. For example, the UE may convert the SBFD symbol / slot to a DL-only symbol / slot. Therefore, by applying the scheme proposed in this disclosure, SBFD operation and SSB measurement can be properly coordinated to ensure the normal operation of the UE.

[0032] Figure 4An example scenario 400 of a communication environment is illustrated, in which various solutions and schemes of this disclosure can be implemented. Scenario 400 involves a UE 410 (e.g., a UE supporting SBFD) communicating wirelessly with a network 420 (e.g., a wireless network comprising a non-terrestrial network (NTN) and a terrestrial network (TN)) via a terrestrial network node 422 (e.g., an evolved Node-B (eNB), a next-generation Node-B (gNB), a transmission / reception point (TRP), or a gateway) and / or a non-terrestrial network node 424 (e.g., a satellite). For example, the terrestrial network node 422 and the non-terrestrial network node 424 may form an NTN serving cell for wireless communication with the UE 410. In this communication environment, the UE 410, network 420, terrestrial network node 422, and / or non-terrestrial network node 424 can implement various schemes related to SSB measurement and SBFD operational coordination as described below. It is worth noting that although the various proposed solutions may be described separately or individually below, in practice, some or all of the proposed solutions may be used or implemented in combination. Of course, each proposed solution may also be used or implemented individually.

[0033] Under the first scheme of this disclosure, when the Synchronization Signal Block (SSB) timing overlaps with a Subband Full-Duplex (SBFD) symbol / slot in time, the User Equipment (UE) may prioritize SSB measurement on the SSB timing rather than performing UL transmission on the SBFD symbol / slot. Specifically, the UE may perform SSB measurement on such SSB timing and may not allow UL transmission on SBFD symbols / slots that overlap with the SSB timing. Figure 5 Two example scenarios 510 and 520, illustrating the coordination of SSB measurement and SBFD operation under a first scheme according to an embodiment of this disclosure, are presented. Figure 5 As shown, the SBFD time slots that overlap with the SSB timing are used for SSB measurements, not UL transmissions.

[0034] In some implementations, the UE may not allow UL transmission on SBFD symbols / slots that overlap with the SSB timing in time and / or frequency domain.

[0035] In some implementations, the UE may treat any UL resource allocation that overlaps with the SSB timing in time and / or frequency domain (i.e., allocation of SBFD symbols / slots for UL) as invalid allocations. For example, the UE may discard any UL resource allocation that overlaps with the SSB timing. For example, the UE may postpone any UL resource allocation that overlaps with the SSB timing.

[0036] Under the second scheme of this disclosure, when the SBFD symbol / slot overlaps with the SSB timing, the UE may allow (or prioritize) UL transmission on the SBFD symbol / slot. Specifically, the UE may perform UL transmission on the SBFD symbol / slot and may skip SSB measurement on the SSB timing that overlaps with the SBFD symbol / slot. Figure 6 Two example scenarios 610 and 620, illustrating the coordination of SSB measurement and SBFD operation under a second scheme according to an embodiment of this disclosure, are presented. Figure 6 As shown, SSB timings that overlap with SBFD time slots in time are skipped to allow UL transmissions on SBFD time slots.

[0037] In some implementations, the UE may treat SSB timings that overlap with UL resources as invalid measurements.

[0038] In some implementations, the UE may only measure SSBs that do not overlap with UL resources on SBFD symbols / slots during the SSB timing / burst.

[0039] In some implementations, the UE may always skip SSB measurements on SSB timings that overlap with UL resources on SBFD symbols / slots. Alternatively, in some implementations, the UE may skip SSB measurements on SSB timings that overlap with UL resources under specific conditions, including: (i) the UE skips SSB measurements only when it is scheduled to perform a UL transmission on an SSB symbol / slot; (ii) the UE skips SSB measurements based on the UL transmission type, for example, skipping SSB measurements for UL transmissions scheduled by downlink control information (DCI), and not skipping SSB measurements for configured / periodic / semi-persistent UL transmissions; (iii) allowing SSB measurements if the UE is not scheduled to perform a UL transmission on an SSB symbol / slot; (iv) skipping SSB measurements if the signal-to-interference noise ratio (SINR) of the measured non-overlapping SSB result is higher than a predefined / configured threshold; or (v) skipping SSB measurements if the UE is not at the cell edge and / or in a low-mobility and / or stationary state.

[0040] In some implementations, the network can indicate to the UE which SSBs should be measured or skipped via higher-layer signaling or layer-1 (L1) signaling. For example, the network can indicate an index of measurable or skippable SSBs, which may or may not overlap with UL transmissions.

[0041] In some implementations, SSB timings / bursts can be configured to follow existing SSB configurations. For example, within an X millisecond measurement window, the UE can be configured with Y SSB timings / bursts, each containing Z SSBs.

[0042] In some implementations, if any SSB in any SSB timing / burst overlaps with UL resources of an SBFD symbol / slot, the UE can extend the configured measurement window to compensate for the overlapping / skipped SSBs. That is, the UE maintains the total number of configured SSBs unchanged regardless of whether some SSBs overlap with UL resources.

[0043] In some implementations, if any SSB in any SSB timing / burst overlaps with UL resources of an SBFD symbol / slot (and the UE actually performs UL transmission within that symbol / slot), the UE can maintain the configured measurement window and not compensate for the overlapping / skipped SSBs. That is, the number of SSBs the UE uses for measurement within an SSB timing / burst is less than the configured number.

[0044] Under the third scheme of this disclosure, the occurrence of an SSB within an SBFD symbol / slot can cover the slot division of that SBFD symbol / slot. Specifically, when the SSB timing overlaps with the UL resources of an SBFD symbol / slot in the time domain or frequency domain, the occurrence of an SSB within an SBFD symbol / slot can cover the slot division.

[0045] In some implementations, when the UL resources of SSB and SBFD symbols / slots overlap in the time domain, only the segmentation of symbols that overlap with the SSB timing in the time domain is covered. Alternatively, when the UL resources of SSB and SBFD symbols / slots overlap in the time domain, the segmentation of all symbols in the SBFD slot may be covered. In some implementations, when the UL resources of SSB and SBFD slots overlap in the frequency domain, the segmentation of all symbols in the SBFD slot is covered.

[0046] In some implementations, if a symbol / slot contains both DL and UL resources, it is segmented; otherwise, the slot is a non-segmented slot.

[0047] In some implementations, coverage may mean that the UE ignores slot segmentation. For example, the UE may treat the slot as a DL-only slot (e.g., converting an SBFD slot containing SSB timings into a DL-only slot, i.e., a slot containing only DL resources), and the network may schedule DL data / measurements on the coverage resources of the SBFD symbols / slots.

[0048] Figure 7 An example scenario 700 is shown, illustrating the coordination of SSB measurement and SBFD operation under a third scheme according to an embodiment of this disclosure. For example... Figure 7As shown, within a semi-radio frame containing an SSB opportunity, the UE treats all SBFD time slots (up to the "reference time slot," i.e., the time slot containing the last SSB opportunity) as full DL time slots (i.e., DL time slots only). The UE can determine the "reference time slot" using existing SSB configuration parameters (provided by higher-layer signaling). For example, the UE can determine the radio frame containing the SSB opportunity, the semi-radio frame containing the SSB opportunity, the index of transmitted SSB opportunities, etc., from higher-layer signaling.

[0049] In some implementations, the user equipment (UE) may be considered to be able to perform DL operations (e.g., physical downlink control channel (PDCCH) monitoring, physical downlink shared channel (PDSCH) reception, channel state information-reference signal (CSI-RS) reception, synchronization signal block (SSB) reception, etc.) only on these time slots (i.e., all SBFD time slots up to the "reference time slot").

[0050] In some implementations, the UE may not expect to perform UL operations on these time slots. For example, the UE may consider any semi-static and / or dynamic UL configurations or resource allocations on these time slots to be invalid.

[0051] In some implementations, within a half-frame containing SSB timings, if any SBFD slots occur after a “reference slot,” the UE may not treat these SBFD slots as full DL slots. That is, the UE may expect to perform UL operations (e.g., physical uplink control channel (PUCCH) transmission, physical uplink shared channel (PUSCH) transmission, sounding reference signal (SRS) transmission, physical random access channel (PRACH) transmission, etc.) on these slots.

[0052] In some implementations, the UE may determine a “reference slot” for all possible SSB configurations within a half-frame containing an SSB, including: (i) SSB configurations with a carrier frequency below 3 GHz; (ii) SSB configurations with a carrier frequency between 3 GHz and 6 GHz; and (iii) SSB configurations with a carrier frequency above 6 GHz.

[0053] Figure 8 This illustrates an example scenario 800 of SSB measurement and SBFD operation coordination under a third proposed scheme, according to an embodiment of this disclosure. Figure 8 As shown, within a half-frame containing an SSB opportunity, the UE treats all SBFD time slots within the "time window" (i.e., the period between the first time slot of the half-frame and the time slot containing the last SSB opportunity) as full DL time slots (i.e., DL-only time slots). The UE can determine the "time window" using existing SSB configuration parameters (provided by higher-layer signaling). For example, the UE can determine the radio frame containing an SSB, the half-frame containing an SSB, the index of transmitted SSBs, etc., from higher-layer signaling.

[0054] In some implementations, the UE may assume that DL operations (e.g., PDCCH monitoring, PDSCH reception, CSI-RS reception, SSB reception, etc.) can only be performed on these time slots (i.e., all SBFD time slots within the "time window").

[0055] In some implementations, the UE may not expect to perform UL operations on these time slots. For example, the UE may consider any semi-static and / or dynamic UL configurations or resource allocations on these time slots to be invalid.

[0056] In some implementations, within a half-frame containing SSB timings, if any SBFD slots occur after a "time window," the UE may not treat these SBFD slots as full DL slots. For example, the UE may expect to perform UL operations (e.g., PUCCH transmission, PUSCH transmission, SRS transmission, PRACH transmission, etc.) on these slots.

[0057] In some implementations, the UE may determine a “time window” for all possible SSB configurations within a half-frame containing an SSB, including: (i) SSB configurations with a carrier frequency below 3 GHz; (ii) SSB configurations with a carrier frequency between 3 GHz and 6 GHz; and (iii) SSB configurations with a carrier frequency above 6 GHz.

[0058] Apart from Figure 7 and Figure 8In addition to the embodiments described above, another implementation under the third proposed scheme of this disclosure considers that within a half-frame containing SSB opportunities, the UE treats any SBFD slots expected to overlap with SSB opportunities as full DL slots (i.e., DL slots only). The UE can determine the slots expected to overlap with SSB opportunities using existing SSB configuration parameters (provided by higher-layer signaling). For example, the UE can determine its carrier frequency, the radio frame containing SSB opportunities, the half-frame containing SSB opportunities, the index of transmitted SSB opportunities, etc., from the higher-layer signaling. Based on the carrier frequency, the UE can determine the total number of expected SSB opportunities within the half-frame containing SSB opportunities. Based on the SSB configuration, the UE can determine all slots in which the total number of expected SSB opportunities will occur within the half-frame containing SSB opportunities. In one example, for a carrier frequency below 3 GHz, a total of four SSB opportunities are expected to occur in the first two slots of the half-frame containing SSB opportunities. In another example, for a carrier frequency between 3 GHz and 6 GHz, a total of eight SSB opportunities are expected to occur in the first four slots of the half-frame containing SSB opportunities.

[0059] In some implementations, a portion of the expected total number of SSB opportunities within a half-frame containing SSB opportunities can be configured as SBFD slots.

[0060] In some implementations, within a semi-radio frame containing an SSB (Secondary Subsequent Bus) opportunity, if any slot where an SSB opportunity is expected is also configured as an SBFD (Single Subsequent Bus) slot, the UE can treat that SBFD slot as a full DL (Low-Level) slot. In one example, the UE can treat any SBFD slot where an SSB opportunity is expected as a full DL slot, even if the SSB opportunity is not actually transmitted on the SBFD slot. In one example, the UE can assume that DL operations (e.g., PDCCH monitoring, PDSCH reception, CSI-RS reception, SSB reception, etc.) can only be performed on these slots. In one example, the UE may not expect to perform UL (Ultra-Level) operations on these slots. The UE can assume that any semi-static and / or dynamic UL configuration or resource allocation on the allocated slots is invalid.

[0061] In some implementations, within a half-frame containing an SSB opportunity, if any SBFD slot does not overlap with any of the expected total number of SSB opportunities, the UE may not treat that SBFD slot as a full DL slot. The UE may expect to perform UL operations (e.g., PUCCH transmission, PUSCH transmission, SRS transmission, PRACH transmission, etc.) on these symbols.

[0062] In some implementations, a time slot is an SBFD time slot if the symbols of a time slot contain both DL and UL resources in the frequency domain; a time slot is a full DL time slot if the symbols of a time slot contain only DL resources in the frequency domain.

Both the communication device 910 and the network device 920 can perform various functions to implement the schemes, techniques, processes, and methods described herein regarding the coordination of SSB measurement and SBFD operations, including the aforementioned scenarios / schemes and processes 1000 and 1100 described below.

It may also include one or more other components unrelated to this disclosure (e.g., internal power supply, display device, and / or user interface device); therefore, for the sake of brevity, these components of the communication device 910 are not listed in the disclosure. Figure 9 It is shown in the text and is not described in the following text.

[0091] Additional Notes

[0092] The topics described herein sometimes demonstrate that different components are contained within or connected to other components. It should be understood that such architectures are merely examples, and many other architectures can actually be implemented to achieve the same functionality. Conceptually, any arrangement of components to achieve the same functionality is effectively “associated” to achieve the desired function. Therefore, any two components combined in this document to achieve a specific function can be considered “associated” with each other to achieve the desired function, regardless of the architecture or intermediate components. Similarly, any two components so associated can also be considered “operably connected” or “operably coupled” to achieve the desired function, and any two components that can be so associated can also be considered “operably coupled” to achieve the desired function. Specific examples of operable coupling include, but are not limited to, physically matable and / or physically interactive components and / or wirelessly interactive and / or logically interactive components.

[0093] Furthermore, regarding the use of almost all plural and / or singular terms in this document, those skilled in the art can appropriately convert plural to singular and / or singular to plural depending on the context and / or application. For clarity, various singular / plural permutations may be explicitly listed herein.

[0094] Furthermore, those skilled in the art will understand that the terms used herein, particularly in claims, such as the body portion of a claim, are generally intended to be “open” terms; for example, “comprising” should be interpreted as “comprising but not limited to,” “having” should be interpreted as “having at least,” and “including” should be interpreted as “including but not limited to,” etc. Those skilled in the art will also understand that if a specific number of claim elements is explicitly expressed in the claim, that intention is explicitly expressed in the claim; if it is not expressed, then that intention does not exist. For example, for ease of understanding, a claim may include the introductory phrases “at least one” and “one or more” to introduce claim elements. However, the use of such phrases should not be interpreted as limiting any particular claim containing that element to containing only one of that element by introducing the claim element with the indefinite article “one” or “one of,” even if the same claim contains the introductory phrases “one or more” or “at least one” and indefinite articles such as “one” or “one of,” for example, “one” and / or “one of” should be interpreted as “at least one” or “one or more”; the same applies to the use of definite articles to introduce claim elements. Furthermore, even when a specific number of elements in a claim is explicitly stated, those skilled in the art will recognize that such a statement should be interpreted as at least the stated number. For example, expressing "two elements" without any other modifiers indicates at least two elements, or two or more elements. Additionally, when using conventions such as "at least one A, B, and C, etc.", this structure is generally intended to convey the meaning understood by those skilled in the art. For example, "a system having at least one A, B, and C" includes, but is not limited to, systems with only A, only B, only C, A and B, A and C, B and C, and systems where A, B, and C are present simultaneously. Similarly, when using conventions such as "at least one A, B, or C, etc.", this structure is generally intended to convey the meaning understood by those skilled in the art. For example, "a system having at least one A, B, or C" includes, but is not limited to, systems with only A, only B, only C, A and B, A and C, B and C, and systems where A, B, and C are present simultaneously. Those skilled in the art will also understand that almost all disjunctive terms and / or phrases appearing in the specification, claims, or drawings, when two or more alternative terms are proposed, should be understood to include one, any, or both terms. For example, the phrase “A or B” should be understood as including the possibility of “A” or “B” or “A and B”.

[0095] As can be seen from the foregoing, various embodiments of this disclosure have been described herein for illustrative purposes, and various modifications can be made without departing from the scope and spirit of this disclosure. Therefore, the various embodiments disclosed herein are not intended to be limiting, and the true scope and spirit are indicated by the claims.
