[0030] The technical matters, structural features, objectives and effects of the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. Specifically, the terms in the embodiments of the present disclosure are only used for the purpose of describing specific embodiments, rather than limiting the present disclosure.

[0031] In the 3rd Generation Partnership Project (3GPP) new radio (NR), which is the fifth generation (5G) radio access technology (RAT) based on orthogonal frequency division multiplexing (OFDM), the radio resources for downlink and uplink are defined on a two-dimensional time-frequency resource plane. The downlink is the transmission direction from the base station (BS, or so-called gNB in ​​3GPP NR) to the user equipment (UE), and the uplink is the transmission direction from the UE to the base station. On the resource plane, the smallest resource unit called "resource element" (RE) is defined, which corresponds to one subcarrier in the frequency domain and one OFDM symbol in the time domain. In the frequency domain, twelve consecutive subcarriers constitute a resource block (RB), which is the minimum resource allocation granularity in the frequency domain. In the time domain, one OFDM symbol is the minimum resource allocation granularity. Seven consecutive OFDM symbols constitute a time slot.

[0032] Starting from 3GPP NR release 17, an OFDM symbol can be configured through radio resource control (RRC) layer signaling for the UE to use as one of {downlink symbol, uplink symbol, flexible symbol}, where: From the UE's perspective, downlink symbols can be used only for downlink reception. The UE cannot use downlink symbols for uplink transmission. From the UE's perspective, uplink symbols can be used only for uplink transmission. The UE cannot use uplink symbols for downlink reception. From the UE's perspective, flexible symbols can be used for downlink reception or uplink transmission, depending on further dynamic allocation in real-time base station scheduling. However, in time division duplex (TDD) spectrum, the UE does not perform both downlink reception and uplink transmission in the same OFDM symbol. In other words, in TDD spectrum, NR UEs do not need to support full-duplex mode (as opposed to half-duplex).

[0033] As is traditional in TDD spectrum, when a UE switches its radio frequency (RF) unit from downlink reception to uplink transmission, there is some guard time around the switching instance. In contrast, when the RF switches from uplink to downlink, no guard time is required.

[0034] As of NR Release 17, there are two levels of TDD uplink / downlink (UL / DL) configurations: Cell-specific TDD UL / DL configuration via RRC information element (IE) “tdd-UL-DL-ConfigurationCommon”: It defines the UE-common periodicity pattern for TDD uplink / downlink allocation of OFDM symbols in the time domain, where each periodicity pattern contains a certain number (L D ) of continuous downlink symbols, followed by a certain number (LF) of continuous flexible symbols, and then a certain number (L U ) for consecutive uplink symbols. For TDD UE, "tdd-UL-DL-ConfigurationCommon" must be supported. UE-specific TDD UL / DL configuration via RRC Information Element (IE) "tdd-UL-DL-ConfigurationDedicated": It redefines each flexible symbol in "tdd-UL-DL-ConfigurationCommon" as one of {downlink symbol, uplink symbol, flexible symbol}, but cannot change downlink symbols or uplink symbols in "tdd-UL-DL-ConfigurationCommon" to flexible symbols or symbols in the opposite direction. Supporting "tdd-UL-DL-ConfigurationDedicated" is an optional UE capability.

[0035] When it comes to NR version-18, a duplex enhancement is proposed in 3GPP to support full-duplex operation on the base station side in the TDD carrier while maintaining half-duplex operation on the user equipment side. For example, in a TDD carrier, a base station can simultaneously send a downlink signal to one UE and receive an uplink signal from another UE, but no single UE will perform downlink reception and uplink transmission at the same time. Here, "simultaneously" means "in the same OFDM symbol". In addition, since the base station needs to provide services for legacy UEs that may not support "tdd-UL-DL-ConfigurationDedicated" and the number of flexible symbols configured for legacy UEs may be limited, the number of flexible symbols in "tdd-UL-DL-ConfigurationCommon" may be limited in real-world deployments. Therefore, it is not enough to rely on traditional flexible symbols to provide full-duplex operation on the base station side.

[0036] In 3GPP, it is proposed to reallocate some resources in one or more downlink symbols for uplink use, and / or to reallocate some resources in one or more uplink symbols for downlink use. This resource reallocation is proposed to be achieved through "duplex subbands", which are defined as a group of consecutive resource blocks (RBs) in the frequency domain, which are scheduled by the base station to ensure that the same duplex direction (i.e., the transmission direction configured for the resources within the duplex subband) is selected between the downlink and the uplink. Each duplex subband is associated with a subband bandwidth in the frequency domain and a time span in the time domain.

[0037] In order to implement downlink reception scheduling and uplink transmission authorization in 5G-NR, the base station needs to notify the UE of the frequency domain resources for UE reception or transmission through scheduling / authorization signaling. In 3GPP NR, both downlink frequency domain resource allocation (FDRA) and uplink FDRA have three types: Type 0 FDRA only: In type 0 FDRA, the resource block allocation information in the FDRA includes a bitmap indicating the resource block groups (RBGs) allocated to the scheduled UE, and each bit in the bitmap represents an RBG containing P consecutive resource blocks (RBs), where P is in the form of 2 k (1≤k≤4) and can be derived based on the radio resource control (RRC) layer configuration and the frequency bandwidth of the corresponding bandwidth part (BWP). The number of bits in the bitmap is determined as in and They are the size and starting position of BWP respectively, both in RB. Type 1 FDRA only: In Type 1 FDRA, the resource block allocation information in the FDRA indicates to the scheduled UE that the resource block allocation is in a size of A set of contiguous allocated resource blocks within an active BWP. RB allocations can start from any single RB and contain any number of RBs subject to BWP boundaries. 3GPP NR has designed a specific resource indication value (RIV) coding scheme to indicate the number of resource blocks allocated in a BWP. Any number of consecutive RBs selected from any RB position within RBs, the bit length of this indication is equal to The corresponding RIV coding is defined as follows: The downlink type 1 resource allocation field consists of a resource indicator value (RIV) corresponding to the starting virtual resource block (RB 起始) and the length L of the consecutively allocated resource blocks RBs The resource indicator value is defined as follows: if but otherwise in Dynamic switching between type 0 FDRA and type 1 FDRA: The bit size of the FDRA field of the signaling is Among them, the first most significant bit (most-significant-bit, MSB) is used to indicate whether the remaining field bits are used to indicate type 0 FDRA or type 1 FDRA. Each of the above FDRA schemes is applicable to one BWP on one frequency carrier.

[0038] When a duplex subband for uplink is configured for a UE within an OFDM downlink symbol, if the base station does not authorize the UE to perform any uplink transmission in the duplex subband on the OFDM symbol, the base station scheduling preferably retains the ability to schedule downlink reception in the OFDM symbol. In other words, if the OFDM symbol is not used for uplink transmission by the UE, it can still be used for downlink reception by the UE.

[0039] Some embodiments of the present disclosure provide a device for resource allocation and a wireless communication method, such as a solution for indicating frequency domain resource allocation in a symbol with a duplex subband, wherein the transmission direction of the frequency domain resource allocation is opposite to the transmission direction of the duplex subband. For example, some embodiments of the present disclosure are particularly applicable to 3GPP NR systems. In addition, for example, some embodiments of the present disclosure provide a new signaling method for scheduling downlink reception for a UE on an OFDM downlink symbol of a duplex subband for which an uplink is configured for the UE.

[0040] Figure 1It is shown that in some embodiments, a user equipment (UE) 10 and a base station 20 (e.g., gNB) communicating in a communication network system 30 (e.g., NR system) according to an embodiment of the present disclosure are provided. The communication network system 30 includes the UE 10 and the base station 20. The UE 10 may include a memory 12, a transceiver 13, and a processor 11 coupled to the memory 12 and the transceiver 13. The base station 20 may include a memory 22, a transceiver 23, and a processor 21 coupled to the memory 22 and the transceiver 23. The processor 11 or 21 may be used to implement the proposed functions, processes, and / or methods described in this specification. The layers of the radio interface protocol may be implemented in the processor 11 or 21. The memory 12 or 22 is operably coupled to the processor 11 or 21 and stores various information for operating the processor 11 or the processor 21. The transceiver 13 or 23 is operably coupled to the processor 11 or 21, and the transceiver 13 or 23 sends and / or receives radio signals.

[0041] The processor 11 or 21 may include an application specific integrated circuit (ASIC), other chipsets, logic circuits and / or data processing devices. The memory 12 or 22 may include a read-only memory (ROM), a random access memory (RAM), flash memory, a memory card, a storage medium and / or other storage devices. The transceiver 13 or 23 may include a baseband circuit for processing radio frequency signals. When the embodiment is implemented in software, the techniques described herein may be implemented with modules (e.g., processes, functions, etc.) that perform the functions described herein. The modules may be stored in the memory 12 or 22 and executed by the processor 11 or 21. The memory 12 or 22 may be implemented within the processor 11 or 21, or implemented outside the processors 11 and 21, in which case the memory 12 or 22 may be communicatively coupled to the processor 11 or 21 via various means known in the art.

This can solve the problems in the prior art and other problems, and / or solve the problem of scheduling the physical downlink shared channel (PDSCH) in the OFDM symbol configured with the blocking band. In some examples, the signaling can be downlink control information (DCI). Specifically, in some examples, the processor 11 is configured with a blocking band in the frequency domain on the OFDM symbol by radio resource control (RRC) signaling. In some examples, the processor 11 is configured to determine by DCI whether a resource block (RB) in the blocking band can be used for physical downlink shared channel (PDSCH) allocation. In some examples, the blocking band can refer to a resource block (RB) in the frequency domain, and can indicate whether these RBs can be used for the scheduled PDSCH resource allocation. In some examples, the blocking band can refer to a downlink (DL) blocking band. For example, to support an uplink (UL) subband in a DL OFDM symbol, a group of contiguous RBs including the UL subband and the guard band may be potentially reserved as unavailable for DL ​​resource allocation. Some embodiments name the group of contiguous RBs a downlink blocking band and address issues and other issues when scheduling PDSCH in an OFDM symbol configured with a downlink blocking band.

[0043] In some embodiments, the processor 21 may configure a blocked frequency band in the frequency domain on an OFDM symbol to the UE 10, and the processor 21 may indicate to the UE 10 through signaling whether a resource block (RB) in the blocked frequency band is available for physical downlink shared channel (PDSCH) allocation.

[0048] In some embodiments, RBs in the blocked frequency band are not available for PDSCH allocation.

In some embodiments, the indication provided by signaling is a single-bit information field. In some embodiments, if the frequency domain start boundary and / or the frequency domain end boundary allocated by signaling are located in a blocked frequency band, the indication provided by signaling indicates that the RBs allocated by signaling and located in a blocked frequency band may be used for PDSCH allocation.

[0063] In some embodiments, RBs in a blocked frequency band may be used for PDSCH allocation. In some embodiments, signaling provides an indication of whether an RB allocated by signaling and located in a blocked frequency band may be used for PDSCH allocation. In some embodiments, the indication provided by signaling is a single-bit information field. In some embodiments, if the frequency domain start boundary and / or the frequency domain end boundary allocated by signaling are located in a blocked frequency band, the indication provided by signaling indicates that the RBs allocated by signaling and located in a blocked frequency band may be used for PDSCH allocation.

In some embodiments, Φ is the set of all RB allocation sizes with even or odd numbers.

[0065] An exemplary technical solution is shown below.

[0066] Figure 8 Uplink (UL) subbands and downlink (DL) blocked bands in a DL symbol are shown for implementing some embodiments presented herein. Figure 8 It is shown that in some embodiments, from the perspective of the base station, if downlink resources and uplink resources exist simultaneously in one OFDM symbol, there is a guard band (or guard frequency band) between adjacent downlink resources and uplink resources, such as Figure 8As shown. In other words, if the OFDM resources within the uplink subband are used as uplink resources, the resources that are not available for downlink in the OFDM symbol include resources within the uplink subband and resources within two guard bands surrounding the uplink subband. From the UE's perspective, the UE may not need to know the uplink subband and guard bands configured for another UE. All the UE needs to know is the resource band that cannot be used as a downlink resource - in some embodiments of the present disclosure, it is called a "blocking band", which is a collection of uplink subbands and surrounding guard bands. As Figure 8 As shown, the uplink subband in the DL symbol is protected by the blocking frequency band, and the bandwidth (BW DL-BLK ) is not less than the bandwidth of the uplink subband (BW UL-SB For example, the bandwidth of the blocking band (BW DL-BLK ) is always no less than the uplink subband bandwidth (BW UL-SB ).

[0067] Fig. 9 DL resource allocation with DL blocked frequency bands unavailable for DL ​​is shown for implementing some embodiments presented herein. Fig. 9 It is shown that in some embodiments, for a UE configured with a blocked frequency band in an OFDM symbol, the downlink scheduling signaling for allocating downlink resources in the symbol to the UE may have the following two alternatives:

[0068] Alternative 1: If Fig. 9 As shown, before the UE decodes the downlink scheduling signaling, the UE knows that the resources in the blocked frequency band are not available for downlink resource allocation. In other words, the scheduled downlink resources need to skip the resources in the blocked frequency band. For example, the downlink resources are allocated in symbols, where the blocked frequency band is always not available for downlink resource allocation.

[0069] Alternative 2: Fig.10 DL resource allocation with DL blocked bands available or unavailable for DL ​​is shown for implementing some embodiments presented herein. Fig.10 It is shown that in some embodiments, before the UE decodes the downlink scheduling signaling, the UE does not know whether the resources in the blocked frequency band are available for downlink resource allocation. Fig.10 As shown, if the uplink subband in the symbol is not used for any UE, the guard band needs to be applied, and thus the resources in the entire blocking band configured for UE-1 can be used for downlink resource allocation scheduled for UE-1. If the uplink subband in the symbol is used for another UE (UE-2), the guard band is maintained, and thus the resources in the blocking band configured for UE-1 cannot be used for downlink resource allocation scheduled for UE-1.

[0070] In alternative 1, if Fig. 9 As shown, the effective downlink resource bandwidth is the total downlink bandwidth Subtract the bandwidth of the blocking band (BW DL-BLK ), which makes it possible to use fewer FDRA field bits in scheduling signaling. Assuming BW DL-BLK equal resource blocks (RBs), then the existing calculation formula for determining the FDRA field size is Replace with More specifically, the new FDRA field size is given by at least one of the following.

[0071] For type 0 only FDRA,

[0072] For Type 1 only FDRA,

[0073] For dynamic switching between the Type 0 FDRA and the Type 1 FDRA,

[0074] In alternative 1, Type 1 FDRAs need to have a new resource indication value (RIV) derivation corresponding to the starting resource block index (RB 起始 ) and the length (L) expressed in terms of the number of consecutively allocated resource blocks RBs ). Please note that L RBs is the number of RBs allocated to the UE, which may include RBs from blocked bands. Assume that the blocked bands are indexed at resource blocks (RBs). Starts at and includes RBs, of which and Equivalent to Fig. 9 BW in 下 and BW DL-BLK . RBs can be continuous RBs. Continuous RBs can be continuous RBs in the frequency domain. The starting RB and the ending RB of the downlink resource allocation are not in the blocked frequency band, that is, RB 起始 and (RB 起始 +L RBs ) are not in ), then the new RIV code is as follows:

[0075] Note: Refers to the equivalent bandwidth after removing the DL blocking frequency band. A 起始 Refers to the equivalent starting RB index after removing the DL blocking frequency band. if but otherwise, A 起始 =RB 起始 . A len Refers to the equivalent number of allocated RBs available for PDSCH after removing the DL blocked frequency band. if and but otherwise, A len =L RBs . RIV derivation: Use the existing RIV derivation, but add Replace with RB 起始 Replace with A 起始 , L RBs Replace with A len . if but otherwise, in,

[0076] Thus, in some examples, the RIV received by the UE may be decoded as follows:

[0077] Step-1: Use conventional RIV decoding to obtain {A 起始 , A len}, where Replace with

[0078] Step-2: From Recovery 起始 , L RBs}, as shown below:

[0079] if but Otherwise, RB 起始 =A 起始 .

[0080] if and but Otherwise, L RBs=A len .

[0081] It should be noted that in some cases, 5G-NR Type-1 downlink resource allocation can be allocated in units of K>1 RB in addition to K=1 RB as assumed in the above description. For these cases, the principles and algorithms described in

[0010] to

[0011] above still apply, but Each parameter in is replaced by 1 / K of its value.

[0082] The above method in alternative solution 1 is intended to reduce the overhead of the FDRA field in scheduling signaling. Then the above method is meaningful and applicable only if it can indeed reduce the FDRA overhead. Therefore, in some embodiments, the above method of alternative solution 1 is based on the following conditions: For type 0 only FDRA, For Type 1 only FDRA, For dynamic switching between type 0 FDRA and type 1 FDRA,

[0083] In alternative solution 2, the downlink scheduling signaling indicates to the scheduled UE whether the resources in the configured blocked frequency band can be used as downlink resources for the resource allocation scheduled by the signaling. Fig.10 As shown, if the scheduling signaling indicates yes, the scheduled downlink resources are allocated as if there is no blocked frequency band. If the scheduling signaling indicates no, the scheduled downlink resources are allocated according to the traditional scheduling scheme, but any allocated downlink resources falling into the blocked frequency band are not available for downlink reception of the scheduled UE. For example, the downlink reception of the UE needs to skip the resources in the blocked frequency band configured for the UE.

[0084] In alternative 2, the above-mentioned binary signaling indication can be implemented by an explicit single-bit information field or an implicit indication. The implicit indication can come from an existing PDSCH-scheduling signaling content / attribute or a combination of multiple existing PDSCH-scheduling signaling content / attributes. For example, the signaling attributes between unicast scheduling and non-unicast scheduling can be used for implicit indication: the configured DL blocking frequency band is effective for unicast scheduling, but not for non-unicast scheduling. Some embodiments of the present disclosure focus on implicit indications through the FDRA field itself. More specifically, because the FDRA field of the PDSCH-scheduling signaling informs two pieces of information: the start / end boundaries of the PDSCH allocation in the frequency domain and the size of the PDSCH allocation in the frequency domain (for example, the number of RBs allocated for PDSCH by signaling), the implicit indication can be contained in the start / end boundaries of the allocation derived from the FDRA information or in the size of the allocation derived from the FDRA information.

[0085] Fig.11 An indication of whether a DL blocked subband is in effect for implementing some embodiments presented herein is shown. For example, Fig.11 Various implicit indication methods are shown, where the PDSCH resource allocation implicitly indicates whether the configured blocking band is in effect (ie, whether the allocated PDSCH RBs overlapping the blocking band are unavailable for PDSCH). Fig.11 In some embodiments, for implicit indication of the start / end boundaries based on the allocation, such as Fig.11 As shown, since it does not make much sense to make the start boundary or the end boundary or the start and end boundaries of the PDSCH allocation fall within the DL blocking frequency band when the DL blocking frequency band is in effect, considering that the same allocation effect can be achieved through different allocations, these types of RB allocations for PDSCH (the start or end or even both boundaries are located within the blocking frequency band) can be used to implicitly indicate that the DL blocking frequency band is not in effect (i.e., the allocated RBs falling within the DL blocking frequency band can be used for PDSCH). On the contrary, if the frequency domain start boundary and the end boundary of the RB allocation for PDSCH are both outside the DL blocking frequency band, such an allocation implicitly indicates that the DL blocking frequency band is in effect (i.e., the allocated RBs falling within the DL blocking frequency band cannot be used for PDSCH).

[0086] For the frequency domain size based on the allocation (denoted as L RBs ), such as Fig.11 As shown, implicit indication can be based on L RBs A binary output function (e.g., a Boolean function) as an input parameter. Quite a few functions serve this purpose, for example: whether L RBs (or L RBs / K, where K is mentioned in some of the above embodiments) is an even number or an odd number. More generally, LRBs ∈Φ may indicate that the DL blocking band is effective for the scheduled PDSCH, and It may be indicated that the DL blocked subbands are not effective for the scheduled PDSCH, where Φ is a predefined or even configured set of values ​​for the PDSCH allocation size in the frequency domain.

[0087] The implicit indication based on the allocation size and the implicit indication based on the start / end boundary of the allocation can be combined. For example, if any of the following two conditions are met, the DL blocking frequency band configured for the UE is not effective for the PDSCH allocation scheduled by signaling for the same UE; otherwise, the DL blocking frequency band is effective for the PDSCH allocation.

[0088] Condition-1: The start boundary or the end boundary or even the start and end boundaries of the PDSCH allocation in the frequency domain fall into the DL blocking frequency band.

[0089] Condition-2: The start and end boundaries of the PDSCH allocation in the frequency domain fall outside the DL blocking frequency band, and the PDSCH allocation size (L RBs )satisfy or in is the complement of Φ.

[0090] In implementation, the above-described method and its variants may be implemented as computer software instructions or firmware instructions. Such instructions may be stored in an article having one or more machine-readable storage devices connected to one or more computers or integrated circuits or digital processors (such as digital signal processors and microprocessors). In the communication system of the 3GPP new air interface, the FDRA field determination in the base station and the user equipment and the related signal processing may be implemented in the form of software instructions or firmware instructions for execution by the processor in the transmitter and receiver or the transmitting and receiving controller. In operation, the instructions are executed by one or more processors to enable the transmitter and receiver or the transmitting and receiving controller to perform the described functions and operations. Based on what is described herein, other changes and enhancements may also be made.

[0091] In summary, in some embodiments of the present disclosure, in order to support the UL subband in the DL OFDM symbol, a group of continuous RBs including the UL subband and the guard band can be potentially reserved as unavailable for DL ​​resource allocation. Some embodiments of the present disclosure name this group of continuous RBs as a blocking band, and can solve the problem of scheduling PDSCH in an OFDM symbol configured with a downlink blocking band. For example, if the specification stipulates that resources in the blocking band are not available for PDSCH resource allocation, the FDRA field in the PDSCH scheduling signaling can be improved to use a smaller number of bits to save signaling overhead. For example, a new RIV derivation is also innovated. For example, if it is possible to instantly indicate whether resources in the blocking band are available for scheduled PDSCH resource allocation, both explicit indication and implicit indication are provided.

[0092] The commercial benefits of some embodiments are as follows. 1. Solve the problems in the prior art and other problems. 2. Solve the problem when scheduling the physical downlink shared channel (PDSCH) in an OFDM symbol configured with a blocking frequency band. 3. Provide good communication performance. 4.
