[0026] This disclosure will now be described in detail below with reference to the accompanying drawings, which form part of this disclosure and illustrate specific examples of embodiments by way of illustration. However, it should be noted that this disclosure may be embodied in a variety of different forms, and therefore, the subject matter covered or claimed is intended to be construed as not being limited to any of the embodiments set forth below.

[0027] Throughout the specification and claims, terms may have subtle meanings implied or implied in the context, rather than explicitly stated meanings. Similarly, the phrases “in one embodiment” or “in some embodiments” as used herein do not necessarily refer to the same embodiment, and the phrases “in another embodiment” or “in other embodiments” as used herein do not necessarily refer to different embodiments. For example, the claimed subject matter is intended to encompass, in whole or in part, exemplary embodiments or combinations of embodiments.

[0028] Generally, terms can be understood, at least in part, from their usage in the context. For example, terms such as “and,” “or,” and “and / or” as used herein can include a variety of meanings, which can depend at least in part on the context in which these terms are used. Typically, “or,” when used in an associative list such as A, B, or C, is intended to indicate A, B, and C in the sense of inclusion, and A, B, or C in the sense of exclusivity. Furthermore, the terms “one or more” or “at least one” as used herein, at least in part on the context, can be used to describe any feature, structure, or characteristic in a singular sense, or can be used to describe a combination of features, structures, and characteristics in a plural sense. Similarly, terms such as “a,” “an,” or “the” can also be understood to convey singular or plural usage, at least in part on the context. Moreover, the terms “based on” or “determined by” can be understood not necessarily to convey a set of exclusive factors, but rather to allow for the existence of additional factors that are not necessarily explicitly described, again at least in part on the context.

[0029] This disclosure describes methods and apparatus for configuring time-frequency resources in half-duplex and / or full-duplex telecommunications systems.

[0030] Next-generation (NG) mobile communication systems are propelling the world towards an increasingly interconnected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between user equipment and radio access network nodes (including but not limited to radio base stations). NG networks promise to provide high-speed, low-latency, and ultra-reliable communication capabilities, meeting the requirements of various industries and users.

[0031] With the rapid development of cellular mobile communication systems, half-duplex and / or full-duplex technologies may be crucial features for further improving the efficiency and performance of next-generation mobile communication technologies. Half-duplex or full-duplex technologies can utilize time-frequency resources to achieve either half-duplex or full-duplex operation. However, there are challenges / problems associated with implementing half-duplex and / or full-duplex technologies. One such challenge / problem may involve the allocation of time-frequency resources under half-duplex and / or full-duplex technologies.

[0032] In some implementations, full-duplex technology can achieve full-duplex operation using different frequency resources at the same time (i.e., the same time slot) in the time domain. In other implementations, half-duplex mode can be used, i.e., transmitting or receiving only at specific times, to avoid increasing the complexity of the implementation. For example, in a time division duplex (TDD) system, TDD spectrum resources can be divided into downlink (DL) and uplink (UL) in the time domain to transmit uplink data and downlink data. Therefore, for a conventional TDD system, only uplink or downlink can be executed in each cycle. To further improve the efficiency of TDD systems, TDD systems can support full-duplex operation, enabling the TDD system to support both uplink and downlink simultaneously in each cycle of the time domain.

[0033] In some implementations, full-duplex technology may lead to increased complexity and / or cost, particularly for user equipment (UE), due to its ability to support uplink and downlink extensions in each cycle in the time domain.

[0034] In some implementations, compromise solutions can be adopted to mitigate increased complexity and / or cost to some extent. For example, but not limited to, in a TDD system, the base station can support full-duplex, meaning it supports both uplink and downlink simultaneously within a time period; while the UE can support half-duplex but not full-duplex, meaning the UE may not support both uplink and downlink simultaneously in the time domain, but can support them at different times. Utilizing half-duplex technology, these implementations can maintain low UE cost and / or low complexity; and / or such compromise solutions can also improve the efficiency of the TDD system.

[0035] To support this full-duplex or half-duplex technology, this patent application proposes a novel time-frequency resource and slot / frame structure configuration method that helps to reduce interference between the uplink and downlink, and also maximizes resource efficiency.

[0036] Figure 1A wireless communication system 100 is illustrated, comprising a wireless network node 118 and one or more user equipment (UE) 110s. The wireless network node may include a network base station, which may be a Node B (NB, e.g., gNB) in a mobile telecommunications environment. Each UE may wirelessly communicate with the wireless network node via one or more radio channels 115 for downlink / uplink communication. For example, a first UE 110 may wirelessly communicate with the wireless network node 118 via a channel including multiple radio channels during a specific time period. The network base station 118 may send higher-layer signaling to the UE 110. This higher-layer signaling may include configuration information for communication between the UE and the base station. In one embodiment, the higher-layer signaling may include a Radio Resource Control (RRC) message.

[0040] Reference Figure 3The communication interface 302 may include radio frequency (RF) transmit (Tx) and receive (Rx) circuitry 316 that processes the transmission and reception of signals via one or more antennas 314. The communication interface 302 may include one or more transceivers.

[0042] This disclosure describes various embodiments for configuring time-frequency resources in half-duplex and / or full-duplex telecommunications systems, which may be partially or wholly described above.

Various embodiments of this disclosure can achieve efficient time-frequency resource configuration in half-duplex and / or full-duplex telecommunications systems, which can reduce the implementation complexity of gNBs and / or UEs, increase resource utilization efficiency, and / or improve latency performance of URLLC traffic.

[0043] Reference Figure 4AThis disclosure describes various embodiments of a method 400 for wireless communication. The method may include some or all of the following steps: step 410, where a user equipment (UE) receives first signaling for configuring a first time slot structure, the first time slot structure comprising a set of OFDM symbols with an orthogonal frequency division multiplexing (OFDM) symbol attribute of a first symbol attribute; step 420, where the UE receives second signaling for configuring a second time slot structure, the second time slot structure comprising changing the symbol attribute of the set of OFDM symbols to a second symbol attribute; and / or step 430, where the UE determines a partial bandwidth based on the second time slot structure, wherein the partial bandwidth comprises at least one symbol from the set of OFDM symbols, the partial bandwidth having the same attribute as the second symbol attribute.

[0044] In various embodiments of this disclosure, the term "change" of a symbol's symbolic attribute in this context may refer to configuring a new symbolic attribute for the symbol compared to its old symbolic attribute, or reversing the old symbolic attribute of the symbol by the new symbolic attribute, or replacing the old symbolic attribute of the symbol with a new symbolic attribute, wherein the new symbolic attribute is different from the old symbolic attribute.

[0045] Reference Figure 4B This disclosure describes various embodiments of a method 450 for wireless communication. The method may include some or all of the following steps: step 460, whereby a base station sends first signaling for configuring a first timeslot structure for a user equipment (UE), the first timeslot structure comprising a set of OFDM symbols with an orthogonal frequency division multiplexing (OFDM) symbol attribute of a first symbol attribute; step 470, whereby the base station sends second signaling for configuring a second timeslot structure for the UE, the second timeslot structure comprising changing the symbol attribute of the set of OFDM symbols to a second symbol attribute; and / or step 480, whereby the base station configures a partial bandwidth based on the second timeslot structure, wherein the partial bandwidth comprises at least one symbol from the set of OFDM symbols, the partial bandwidth having the same attribute as the second symbol attribute.

[0046] In some implementations, the first signaling includes public signaling for at least one UE in the cell; and / or the second signaling includes UE-specific signaling for the UE.

[0047] In some implementations, the first symbolic attribute includes one of an uplink attribute, a downlink attribute, or a flexible attribute; the second symbolic attribute includes one of an uplink attribute or a downlink attribute; and / or the first symbolic attribute and the second symbolic attribute are different.

[0048] In some implementations, the first symbolic attribute is a flexible attribute; the second symbolic attribute is a downlink attribute; and / or the portion of the bandwidth includes the downlink portion of the bandwidth configured for the UE.

[0049] In some implementations, in response to the second set of symbols in the set of OFDM symbols, a common uplink channel is configured to be transmitted: the downlink portion of the bandwidth includes the set of OFDM symbols excluding the second set of symbols.

[0050] In some implementations, in response to the second set of symbols in the set of OFDM symbols, a common uplink channel is configured to be transmitted: the downlink portion of the bandwidth includes the second set of symbols and is configured not to overlap with the common uplink channel in the frequency domain.

[0051] In some implementations, the common uplink channel includes at least one of the following: physical random access channel (PRACH), cell common physical uplink control channel (PUCCH) resources, uplink (UL) initial portion bandwidth, reference signal, demodulation reference signal (DMRS), or sounding reference signal (SRS).

[0052] In some implementations, in response to the first set of OFDM symbols, a second set of symbols is configured as part of the initial uplink bandwidth, and the initial uplink bandwidth overlaps with the downlink bandwidth in the frequency domain: the downlink bandwidth includes the first set of OFDM symbols other than the second set of symbols, and / or the second set of symbols is considered as uplink symbols.

[0053] In some implementations, the first symbolic attribute is flexible; the second symbolic attribute is uplink; and / or the portion of bandwidth includes the uplink portion of bandwidth configured for the UE.

[0054] In some implementations, in response to a second set of OFDM symbols in the set, the set of OFDM symbols is configured to transmit a common downlink channel: the uplink portion of the bandwidth includes the set of OFDM symbols excluding the second set of symbols.

[0055] In some implementations, in response to a second set of OFDM symbols, the second set of symbols is configured to transmit a common downlink channel: the uplink portion of the bandwidth includes the second set of symbols and is configured not to overlap with the common uplink channel in the frequency domain.

[0056] In some implementations, the common downlink signaling includes at least one of the following: a synchronization signal block (SSB), a control resource set (CORESET) #0, a downlink initial portion bandwidth, a CORESET for the common channel, a system information block (SIB), a reference signal, a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), a positioning reference signal, or a synchronization tracking reference signal.

[0057] In some implementations, in response to a second set of OFDM symbols being configured as part of the downlink initial portion bandwidth, and the downlink initial portion bandwidth overlapping with the uplink portion bandwidth in the frequency domain: the uplink portion bandwidth includes the OFDM symbols other than the second set of symbols, and / or the second set of symbols is considered as downlink symbols.

[0058] In various embodiments, such as Figure 5A , Figure 5B and Figure 5C As shown, the time slot structure of a wireless communication system (e.g., a TDD system) may include one or more OFDM symbols. This time slot structure may include three sets of OFDM symbols: one set of OFDM symbols 515, another set of OFDM symbols 525, and another set of OFDM symbols 535. In some embodiments, each OFDM symbol may be configured with uplink, downlink, or flexible symbol attributes. For example, but not limited to, a time slot may contain 14 OFDM symbols, and each OFDM symbol may be configured with one of three attributes: uplink, downlink, and / or flexible symbol. Flexible symbols can be dynamically modified to be uplink or downlink symbols via signaling. Some signals, such as SSBs, may be allowed to be transmitted in flexible symbols.

[0059] In various embodiments, full-duplex technology can be supported (e.g., including full-duplex on the base station side and half-duplex on the UE side). A time slot structure with resource configuration or frame structure configuration can support both older UEs (e.g., legacy UEs that only support older configurations) and newer UEs (e.g., newer UEs that support both new and older configurations).

[0060] In some implementations, both traditional UEs and new UEs may coexist in a cell or carrier, and three groups (or three types) of UEs in the same cell may be configured with different time slot structures.

[0061] Reference Figure 5A It can configure a time slot structure of 500 for all UEs (legacy UEs and new UEs) in the cell. (Refer to...) Figure 5B This allows configuring a time slot structure 510 for a new UE (or the first new UE (UE1)) in the cell. (Refer to...) Figure 5C It can configure time slot structure 520 for another new UE (or a second new UE (UE2)) in the cell.

[0062] In some implementations, the base station configures the time slot structure for all UEs (traditional UEs and new UEs) via common signaling, enabling all UEs to obtain the time slot structure from the common signaling. For example, as... Figure 5AAs shown, one set of OFDM symbols 515 is configured as DL OFDM symbols with downlink attributes, another set of OFDM symbols 525 is configured as flexible OFDM symbols with flexible attributes, and another set of OFDM symbols 535 is configured as UL OFDM symbols with uplink attributes.

[0063] In some implementations, new signaling (e.g., but not limited to RRC signaling, MAC CE signaling, or DCI signaling) may be introduced and / or used to configure the time slot structure for one or more new UEs in a cell or carrier. Apart from some special signal / channel transmission and reception (such as synchronization signals), the new UE can perform UE-level data transmission and reception according to the time slot structure configured by the new signaling.

[0064] like Figure 5A As shown, the time slot structure 500 is configured as a new UE1 via the cell public signaling, and as... Figure 5B As shown, the base station can also configure a timeslot structure 510 for the new UE 1 using new signaling. The new UE 1 can consider determining the uplink or downlink common signal / channel transmission of the cell based on the timeslot structure configured with common signaling. The new UE 1 can consider determining data transmission and reception (e.g., at least UE-specific data) based on the timeslot structure configured with new signaling.

[0065] like Figure 5B As shown, when a new signaling configuration timeslot structure is implemented, the downlink symbols of the timeslots configured by the common signaling remain unchanged. The uplink symbols of the timeslots configured by the common signaling remain unchanged. The flexible symbols of the timeslots configured by the common signaling are reversed / changed by the new signaling timeslot structure. In this way, the flexible symbols of the timeslots configured by the common signaling can be configured to transmit common downlink signals / channels (such as SSB, CORESET#0, etc.). Therefore, the new UE1 can receive SSB, CORESET#0 (including various common downlink signals / channels) from the flexible symbols in the timeslots configured by the common signaling.

[0066] Optionally, in some implementations, the DL portion bandwidth 531 can be configured for the new UE1 based on the DL symbols in the time slot structure configured by the new signaling. The data transmission of the new UE1 can then be carried out based on the DL portion bandwidth.

[0067] Optionally, in some implementations, the UL portion bandwidth 532 can be configured for the new UE1 based on the UL symbols in the time slot structure configured by the new signaling. The data transmission of the new UE1 can then be carried out based on the UL portion bandwidth.

[0068] Optionally, in some implementations, the new UE1 can receive common downlink signals / channels in DL symbols configured in the common signaling. That is, common downlink signals / channels can only be received in DL symbols configured according to the common signaling.

[0069] In some implementations, the new UE2 may be in the same cell or carrier as the new UE1. Figure 5A The time slot structure configured in the public signaling configuration can also be valid for the new UE2. The base station also uses the new signaling to configure the time slot structure 530 for the new UE2, such as... Figure 5C As shown. The flexible symbols of the time slot structure configured by the common signaling are configured as UL symbols by this new signaling. In this way, two time slot structures (e.g., 500 and 530) are configured for the new UE2, and the transmission and reception of the new UE2 can be based on the time slot structure configured by the new signaling, except for the reception of cell common signals / channels (such as SSB, CORESET#0, etc.).

[0070] In some implementations, the base station can configure the SSB or CORESET#0 to be transmitted in the flexible symbol for all UEs in a cell or carrier based on the time slot structure configured by the common signaling. The flexible symbol for the new UE2 is the UL symbol in the time slot structure configured by the new signaling. The new UE2 can also receive the cell common signal / channel from the UL symbol.

[0071] Optionally, in some implementations, for another example CORESET#0, the new UE2 can receive SSB from the UL symbol. Specifically, the base station and the UE may agree to allow the transmission of SSB and CORESET#0 in the UL symbol, and allow the new UE2 to receive SSB and CORESET#0. Alternatively, the base station and the UE may agree to allow the transmission of SSB in the UL symbol (but not the transmission of CORESET#0), and allow the new UE2 to receive SSB.

[0072] Optionally, in some implementations, the following operation can also be considered for the new UE2: The new UE2 can receive common downlink signals / channels only from the DL symbols configured by common signaling. In this way, combined with the above methods, the new UE2 can avoid receiving common downlink signals / channels from UL symbols.

[0073] Optionally, in some implementations, for the new UE2, based on the UL symbols in the time slot structure configured by the new signaling, the UL portion bandwidth 541 can be configured for uplink data transmission such as dynamically scheduled data, semi-statically transmitted data, and common uplink signals (or channels) can be transmitted in the UL portion bandwidth. In this case, the frequency domain resources of the UL portion bandwidth can be configured to avoid overlap (including partial overlap) with the resources of the cell's common signals / channels. Optionally, in some implementations, the frequency domain resources configured for the UL portion bandwidth may not include the resources of the cell's common signals / channels (e.g., the frequency division between the UL portion bandwidth and the cell's common signals / channels).

[0074] Optionally, in some implementations, the DL portion bandwidth 542 can be configured for the new UE2 based on the DL symbols in the time slot structure configured by the new signaling. The data transmission of the new UE2 can then be carried out based on the DL portion bandwidth.

[0075] As described in the above embodiments / implementations, the three groups / three types of UEs may belong to the same cell or carrier, and the obtained time slot structure may be different for each group / each type of UE; and / or the behavior of different UEs may be based on the configured time slot structure.

[0076] In various embodiments, for method 400 or 450, the first symbolic attribute is a downlink attribute; the second symbolic attribute is an uplink attribute; and / or the portion of the bandwidth includes the uplink portion of the bandwidth configured for the UE.

[0077] In some implementations, in response to a second set of OFDM symbols in the set, the set of OFDM symbols is configured to transmit a common downlink channel: the uplink portion of the bandwidth includes the set of OFDM symbols excluding the second set of symbols.

[0078] In some implementations, in response to a second set of OFDM symbols, the second set of symbols is configured to transmit a common downlink channel: the uplink portion of the bandwidth includes the second set of symbols and is configured not to overlap with the common uplink channel in the frequency domain.

[0079] In some implementations, the common downlink signaling includes at least one of the following: a synchronization signal block (SSB), a control resource set (CORESET) #0, a downlink initial portion bandwidth, a CORESET for the common channel, a system information block (SIB), a reference signal, a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), a positioning reference signal, and / or a synchronization tracking reference signal.

[0080] In some implementations, in response to a second set of OFDM symbols being configured as part of the downlink initial portion bandwidth, and the downlink initial portion bandwidth overlapping with the uplink portion bandwidth in the frequency domain: the uplink portion bandwidth includes the OFDM symbols other than the second set of symbols, and / or the second set of symbols is considered as downlink symbols.

[0081] In various embodiments, reference is made to Figure 6A The middle part of time slot 625 can be a DL OFDM symbol instead of a flexible symbol, the left part of time slot 615 can be a DL OFDM symbol, and the right part of time slot 635 can be a UL OFDM symbol.

[0082] In some implementations, both old and new UEs may coexist in a single cell or carrier. The base station configures the timeslot structure for all UEs via signaling (e.g., common signaling). This is common signaling, therefore all UEs receive the same timeslot structure. In some implementations, Figure 6A The diagram shows a time slot configuration 600, such as configuring symbol attributes within the time slot (such as DL and / or UL).

[0083] In some implementations, refer to Figure 6B For a new UE (e.g., the first new UE, UE1), the configured time slot structure 610 and Figure 6A The time slot structure 600 is the same as in the previous version, and the new UE1 does not need to consider a new processing method. Optionally, in some implementations, the DL portion bandwidth 631 can be configured for the new UE1 based on the DL symbols in the time slot structure. The data transmission of the new UE1 can be transmitted based on the DL portion bandwidth.

[0084] In some implementations, new signaling (such as RRC signaling, MAC CE signaling, or DCI signaling) can be introduced to configure the time slot structure for a new UE in a cell or carrier. Except for some special processing, the new UE performs transmission or reception according to the time slot structure configured by the new signaling. Configuration is then performed for the new UE (e.g., a second new UE, UE2) based on common signaling. Figure 6A The time slot structure 600 shown, and / or the new UE2 configuration based on the new signaling, is as follows: Figure 6C The time slot structure 620 is shown. In this way, the new UE2 obtains the time slot structure 600 with the common signaling configuration and the time slot structure 620 with the new signaling configuration. For the reception of cell common signals / channels (e.g., SSB, CORESET#0, etc.), the new UE2 can perform data transmission and reception in the time slot structure configured by the new signaling, except in the following possible cases.

[0085] In some implementations, when a new signaling configuration timeslot structure is established, the downlink symbols in the timeslots configured by the common signaling are modified to uplink symbols, and the uplink symbols in the timeslots configured by the common signaling can remain unchanged (or may not be flipped). In other implementations, for a new UE2, the DL symbols in the timeslots configured by the common signaling can be changed / reversed from the timeslot structure configured by the new signaling. In this way, for the DL symbols in the timeslots configured by the common signaling, for example, the DL symbols can be configured with UL symbols in the new timeslot structure, which can be configured to transmit common downlink signals / channels, such as SSB, CORESET#0, etc. The new UE2 can receive SSB and / or CORESET#0 (e.g., some common downlink signals / channels) to prevent modification to UL symbols.

[0086] Optionally, in some implementations, the UL portion bandwidth 641 can be configured for the new UE2 based on the UL symbols in the time slot structure configured by the new signaling. In this case, the data transmission of the new UE2 can be transmitted based on the UL portion bandwidth.

[0087] Optionally, in some implementations, the new UE2 may receive common downlink signals / channels in DL symbols configured by common signaling. In some implementations, common downlink signals / channels may be received only in DL symbols configured according to common signaling.

[0088] Optionally, in some implementations, the new UE2 can receive common downlink signals / channels, such as SSB, CORESET#0, etc., from the UL symbol, wherein: the base station and the UE may agree to allow the transmission of common downlink signals or channels in the UL symbol, and may allow the new UE2 to receive common downlink signals / channels in that UL symbol. Optionally, in some implementations, the base station and the UE may agree to allow the transmission of SSB (but not CORESET#0) in the UL symbol, and may allow the new UE2 to receive SSB in that UL symbol.

[0089] Optionally, in some implementations, for a new UE2, a UL portion bandwidth can be configured for uplink data transmission based on the UL symbols in the time slot structure configured by the new signaling. Dynamically scheduled data or semi-static transmissions can be transmitted within the UL portion bandwidth. In this case, the resources of the UL portion bandwidth in the frequency domain can be configured to avoid overlap (including partial overlap) with the resources of the cell's common signals / channels in the frequency domain. Optionally, in some implementations, the frequency resources of the UL portion bandwidth may not include the frequency resources of the cell's common signals / channels, for example, through direct frequency division between the UL portion bandwidth and the cell's common signals / channels. Alternatively, in some implementations, the resources on which the UE is scheduled to transmit data within the UL portion bandwidth do not overlap with the cell's common signals / channels in the time domain.

[0090] In various embodiments, for method 400 or 450, the first symbolic attribute is an uplink attribute; the second symbolic attribute is a downlink attribute; and / or the portion of the bandwidth includes the downlink portion of the bandwidth configured for the UE.

[0091] In some implementations, in response to a second set of OFDM symbols in the set, a common uplink channel is configured to be transmitted: the downlink portion of the bandwidth includes the set of OFDM symbols excluding the second set of symbols.

[0092] In some implementations, in response to a second set of OFDM symbols, the second set of symbols is configured to transmit a common uplink channel: the downlink portion of the bandwidth includes the second set of symbols and is configured not to overlap with the common uplink channel in the frequency domain.

[0093] In some implementations, the common uplink signaling includes at least one of the following: physical random access channel (PRACH), cell common physical uplink control channel (PUCCH) resources, uplink (UL) initial portion bandwidth, reference signal, demodulation reference signal (DMRS), and / or sounding reference signal (SRS).

[0094] In some implementations, in response to a second set of OFDM symbols being configured as part of the uplink initial portion bandwidth, and the uplink initial portion bandwidth overlapping with the downlink portion bandwidth in the frequency domain: the downlink portion bandwidth includes the set of OFDM symbols other than the second set of symbols, and / or the second set of symbols is considered as uplink symbols.

[0095] In some implementations, the first time slot structure and the corresponding symbol attributes are used to determine the configuration and transmission of at least one of the following: a common downlink channel or a common uplink channel.

[0096] In various embodiments, reference is made to Figure 7A The middle part of slot 725 can be a UL OFDM symbol instead of a flexible symbol, the left part of slot 715 can be a DL OFDM symbol, and the right part of slot 735 can be a UL OFDM symbol.

[0097] In some implementations, both old and new UEs may coexist in a single cell or carrier. The base station configures the timeslot structure for all UEs via signaling (e.g., common signaling). This is common signaling, therefore all UEs receive the same timeslot structure. In some implementations, Figure 7A The diagram shows a time slot configuration 700, such as configuring symbol attributes (such as DL and / or UL) within the time slot.

[0098] In some implementations, new signaling (such as RRC signaling, MAC CE signaling, or DCI signaling) can be introduced to configure the time slot structure for a new UE in a cell or carrier. Aside from some special processing, the new UE performs transmission or reception according to the time slot structure configured by the new signaling. Configuration for a new UE (e.g., a first new UE, UE1) can be based on common signaling. Figure 7A The time slot structure 700 shown can then be configured for the new UE1 based on new signaling, as follows: Figure 7B The time slot structure 710 is shown. In this way, the new UE1 can obtain the time slot structure 700 with the common signaling configuration and the time slot structure 710 with the new signaling configuration. For the transmission of cell common signals / channels (e.g., PRACH, cell common PUCCH, etc.) from DL symbols, the new UE1 can perform data transmission and reception in the time slot structure configured by the new signaling, except in the following possible cases.

[0099] In some implementations, when a new signaling configuration slot structure is used, the uplink symbols in the slots configured by the common signaling can be modified to downlink symbols, and the downlink symbols in the slots configured by the common signaling can remain unchanged (or can be left unflipped).

[0100] In some implementations, for a new UE1, the UL symbol in the time slot configured by common signaling is changed / reversed from the time slot structure configured by new signaling. In this way, the UL symbol in the time slot configured by common signaling, for example, the UL symbol can be configured with the DL symbol in the new time slot structure, which can be configured to transmit common uplink signals / channels, such as PRACH, the cell's common PUCCH, etc. The new UE can transmit PRACH and / or the cell's common PUCCH, for example, some common uplink signals / channels, preventing them from being modified to DL symbols.

[0101] Optionally, in some implementations, the DL portion bandwidth 731 can be configured for the new UE1 based on the DL symbols in the time slot structure configured by the new signaling. In this case, at least the new UE1 can receive data at the UE level based on the DL portion bandwidth.

[0102] Optionally, in some implementations, the new UE1 may transmit the cell's common uplink signals / channels in the UL symbols configured in the common signaling. The common uplink signals / channels may be transmitted only in the UL symbols configured according to the common signaling.

[0103] Optionally, in some implementations, regarding the transmission of common uplink signals / channels (such as PRACH, the cell's common PUCCH, etc.) from the DL symbol by the new UE1, the base station and the UE may agree to allow the transmission of common uplink signals / channels in the DL symbol, and may allow the base station to receive common uplink signals / channels in the DL symbol. The base station and the UE may agree to allow the transmission of PRACH (but not the common PUCCH) in the DL symbol, and may allow the base station to receive the PRACH in the DL symbol.

[0104] Optionally, in some implementations, for a new UE1, the DL portion bandwidth 731 can be configured for downlink data transmission based on the DL symbols in the time slot structure configured by the new signaling. Dynamically scheduled data or semi-static transmission can be transmitted in the DL portion bandwidth. The DL portion bandwidth resources in the frequency domain can be configured to avoid overlap (including partial overlap) with the resources of the cell's common downlink signals / channels in the frequency domain. Preferably, the frequency resources of the DL portion bandwidth may not include the frequency resources of the cell's common signals / channels, for example, through direct frequency division between the DL portion bandwidth and the cell's common signals / channels. Alternatively, in some implementations, the resources in the DL portion bandwidth on which the UE is scheduled to receive data do not overlap with the cell's common signals / channels in the time domain.

[0105] In some implementations, refer to Figure 7C For a new UE (e.g., a second new UE UE2), the configured time slot structure 720 is the same as... Figure 7A The time slot structure 700 is the same, and the new UE2 does not need to consider new processing methods. Optionally, in some implementations, the new UE2 may be configured with a UL portion bandwidth 741 based on the UL symbol in the time slot structure. The data transmission of the new UE2 may be transmitted based on the UL portion bandwidth.

[0106] In various embodiments, common uplink channels / signals can be configured and transmitted based on OFDM symbol attributes, according to the configured first time slot structure. For example, within a time slot, some symbols may be configured as uplink or flexible attributes based on the configured first time slot structure, but these symbols are changed to downlink attributes based on the configured second time slot structure. When it is determined that common uplink channels / signals are to be transmitted in these symbols within the time slot based on the configured common uplink channel / signal period and OFDM symbol location, the UE can still transmit common uplink channels or signals in these symbols even though they are changed to downlink attributes based on the configured second time slot structure.

[0107] Similarly, in some implementations, common downlink channels / signals can be configured and transmitted based on OFDM symbol attributes, according to the configured first time slot structure. For example, within a time slot, some symbols may be configured as downlink or flexible attributes based on the configured first time slot structure, but these symbols are changed to uplink attributes based on the configured second time slot structure. When it is determined that common downlink channels / signals are to be transmitted in these symbols within the time slot based on the configured common downlink channel / signal period and OFDM symbol position, the UE can still transmit common downlink channels / signals in these symbols even though they are changed to uplink attributes based on the configured second time slot structure.

[0108] In reference Figure 5A-7C In various embodiments, all UEs can be in the same cell. New UEs can be configured with different time slot structures; for example, the attributes of the same OFDM symbols within a time slot are different from the perspective of different UEs. For all UEs, the common channels or signals of the cell can be transmitted and received based on the time slot structure configured by common signaling. UE-level data reception and transmission are based on the time slot structure configured by UE-specific signaling. The UL portion bandwidth (or DL ​​portion bandwidth) can be configured based on the time slot structure configured by UE-specific signaling. The symbols used by the UL portion bandwidth (or DL ​​portion bandwidth) can be determined based on the symbol attributes corresponding to the time slot structure configured by UE-specific signaling. The optimally configured UL portion bandwidth may not overlap with the cell's common downlink signals / channels in the frequency domain. The optimally configured DL portion bandwidth may not overlap with the cell's common uplink signals / channels in the frequency domain. When the configured UL portion bandwidth overlaps with the cell's common downlink signals / channels in the frequency domain, the symbols used by the UL portion bandwidth skip the symbols of the cell's common downlink signals / channels. If the configured DL portion bandwidth overlaps with the cell's common uplink signal / channel in the frequency domain, then the symbols used by the DL portion bandwidth will skip the symbols of the cell's common uplink signal / channel.

[0109] In some implementations, when the configured UL portion bandwidth and the configured DL portion bandwidth both contain the same symbol, the UE expects the UL portion bandwidth and the DL portion bandwidth to not overlap in the frequency domain.

[0110] In some implementations, when the configured UL portion bandwidth and the configured DL portion bandwidth both contain the same symbol, the UE and the base station agree to use the same symbol for UL transmission or downlink transmission.

[0111] In some implementations, when the UL portion bandwidth and DL portion bandwidth are configured to contain the same symbol, the UE does not expect to perform both UL transmission and DL reception simultaneously in the same symbol.

[0112] In some implementations, the initial portion of the UL or DL ​​bandwidth can be configured based on the time slot structure configured by the public signaling. The symbols used for the initial portion of the UL or DL ​​bandwidth can be determined based on symbol attributes corresponding to the time slot structure configured by the public signaling.

[0113] In some implementations, when the initial UL portion bandwidth is configured to overlap with the UL portion bandwidth in the frequency domain, and when the symbol is a UL symbol in the initial UL portion bandwidth and the symbol is a non-UL symbol in the UL portion bandwidth, the UE expects the symbol to be regarded as a UL symbol in the overlapping region in the frequency domain.

[0114] In some implementations, when the initial portion of the DL bandwidth is configured to overlap with the DL portion bandwidth in the frequency domain, and when the symbol is a DL symbol in the initial portion of the DL bandwidth and the symbol is a non-DL symbol in the DL portion bandwidth, the UE expects the symbol to be regarded as a DL symbol in the overlapping region in the frequency domain.

[0115] In some implementations, the cell’s common uplink signals / channels may include, but are not limited to, the following signals / channels: PRACH, the cell’s common PUCCH resources, UL initial portion bandwidth, and reference signals (e.g., DMRS and / or SRS).

[0116] In some implementations, the common downlink signals / channels of a cell may include, but are not limited to: SSB, CORESET#0, initial portion of the DL bandwidth and CORESET for other common channels, various types of system information blocks, and reference signals (e.g., DMRS, CSI-RS for various purposes, positioning reference signals, synchronization tracking reference signals, etc.).
