Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Application No. 63 / 554,955, filed February 17, 2024, the contents of which are incorporated herein by reference.

[0002] The present invention relates to a method and a communication device for use in a wireless communication system, and more particularly to a method and a communication device for processing downlink (DL) signal reception. [Background technology]

[0003] The Long-Term Evolution (LTE) system, which supports the 3rd Generation Partnership Project (3GPP) Rel-8 and / or 3GPP Rel-9 standards, was developed by 3GPP as the successor to the universal mobile telecommunication system (UMTS) to further improve upon UMTS performance and meet the growing needs of users.

[0004] The LTE-Advanced (LTE-A) system, as its name suggests, is an evolution of the LTE system. The LTE-A system aims to achieve fast switching between power states, improve performance at the coverage edge of evolved Node-B (eNB), increase peak data rates and throughput, and includes advanced technologies such as carrier aggregation (CA) and uplink (UL) multiple-input multiple-output (UL-MIMO).

[0005] Next-generation radio access networks (NG-RANs) supporting 3GPP® Rel-15 to 3GPP® Rel-19 standards are being developed to further enhance the LTE-A system. NG-RANs include one or more next-generation node Bs (gNBs) and have characteristics such as wider operating bands, different numerologies for different frequency ranges, massive MIMO, and advanced channel coding.

[0006] Subband non-overlapping full duplexing (SBFD) is a duplexing mode that divides a time division duplexing (TDD) carrier into subbands and enables simultaneous transmission and reception in the same time period. Together with cross-subband scheduling, networks and communication devices achieve improved UL throughput and reduced latency. However, networks and communication devices experience reduced downlink (DL) throughput from SBFD, which can lead to unsuccessful DL signal reception. Therefore, how to handle DL signal reception has become an important issue to be resolved. Summary of the Invention

[0007] Therefore, the present disclosure provides a method and a communication device for processing downlink (DL) signal reception to solve the above-mentioned problems.

[0008] A method for a communications device for processing DL signal reception includes receiving a first configuration from a network to indicate subband non-overlapping full duplex (SBFD) resources, the first configuration indicating a time period for the SBFD resources and indicating at least one DL subband and an UL subband for the SBFD resources; receiving a second configuration from the network to indicate periodic DL signal reception, the second configuration indicating first frequency domain resources for the periodic DL signal reception; and performing at least one communication operation with the network according to the first configuration and the second configuration.

[0009] A communications device for processing DL signal reception comprises at least one storage device and at least one processing circuit coupled to the at least one storage device, wherein the at least one storage device is configured to store instructions, and the at least one processing circuit is configured to execute the instructions to cause the device to perform the following steps: receiving a first configuration from a network to indicate subband non-overlapping full duplex (SBFD) resources, the first configuration indicating a time period for the SBFD resources and indicating at least one DL subband and an UL subband for the SBFD resources; receiving a second configuration from the network to indicate periodic DL signal reception, the second configuration indicating first frequency domain resources for the periodic DL signal reception; and performing at least one communication operation with the network in accordance with the first configuration and the second configuration.

[0010] A method for a network to configure DL signal reception includes the steps of: transmitting a first configuration to a communication device to indicate subband non-overlapping full duplex (SBFD) resources, the first configuration indicating a time duration for the SBFD resources and indicating at least one DL subband and an UL subband for the SBFD resources; transmitting a second configuration to the communication device to indicate periodic DL signal reception, the second configuration indicating first frequency domain resources for the periodic DL signal reception; and performing at least one communication operation with the communication device according to the first configuration and the second configuration.

[0013] FIG. 1 is a schematic diagram of a wireless communication system 10 according to an example of the present disclosure. The wireless communication system 10, simply stated, includes a network 12 and multiple communication devices 14. The wireless communication system 10 may support a time division duplex (TDD) mode, a frequency division duplex (FDD) mode, a TDD-FDD cooperative operation mode, a non-terrestrial network (NTN) mode, or a licensed assisted access (LAA) mode. That is, the network 12 and the communication devices 14 may communicate with each other via an FDD carrier, a TDD carrier, a licensed carrier (licensed serving cell), and / or an unlicensed carrier (unlicensed serving cell). The wireless communication system 10 may also support carrier aggregation (CA). That is, the network 12 and the communication devices 14 may communicate with each other via multiple serving cells (e.g., multiple serving carriers), including a primary cell (e.g., a primary component carrier) and one or more secondary cells (e.g., secondary component carriers).

[0014] In FIG. 1 , the network 12 and the communication device 14 are used merely to illustrate the configuration of the wireless communication system 10. In practice, the network 12 may be a Universal Terrestrial Radio Access Network (UTRAN) including at least one Node B (NB) in a Universal Mobile Telecommunications System (UMTS). In one example, the network 12 may be an Evolved UTRAN (E-UTRAN) including at least one Evolved NB (eNB) and / or at least one relay node in a Long Term Evolution (LTE) system, an LTE-Advanced (LTE-A) system, an evolution of the LTE-A system, etc. In one example, the network 12 may be a Next Generation Radio Access Network (NG-RAN) including at least one Next Generation Node B (gNB) and / or at least one Fifth Generation (5G) Base Station (BS). In one example, the gNB or 5G BS of the network 12 may include a NTN gateway and an NTN payload. In one example, the gNB or 5G BS of the network 12 may be a Transmit Receiving Point (TRP). In one example, network 12 may be any BS that conforms to a particular communication standard for communicating with communication devices 14 .

[0015] New Radio (NR) is a standard defined for 5G systems (or 5G networks) to provide a unified air interface with superior performance. gNBs are deployed to realize 5G systems that support advanced features such as enhanced Mobile Broadband (eMBB), ultra-reliable and low-latency LAN (URLLC), and massive multi-moderate concurrent connections (mMTC). eMBB provides broadband services with greater bandwidth and low / medium latency. URLLC provides applications (e.g., end-to-end communications) with higher reliability and low latency characteristics. Example applications include the industrial internet, smart grids, infrastructure protection, remote surgery, and intelligent transportation systems (ITS). mMTC can support the Internet of Things (IoT) in 5G systems, which include a large number of connected devices and / or sensors.

[0016] Furthermore, the network 12 may also include at least one of a UTRAN / E-UTRAN / NG-RAN and a core network, where the core network may include network entities such as a mobility management entity (MME), a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), a self-organizing network (SON) server and / or a radio network controller (RNC), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), an authentication server function (AUSF), etc. In one example, after the network 12 receives information transmitted by the communication device 14, the information may be processed only by the UTRAN / E-UTRAN / NG-RAN, and a decision corresponding to the information is made in the UTRAN / E-UTRAN / NG-RAN. In one example, the UTRAN / E-UTRAN / NG-RAN may forward the information to the core network, and a decision corresponding to the information is made in the core network after the core network processes the information. In one example, the information may be processed by both the UTRAN / E-UTRAN / NG-RAN and the core network, and a decision is made after coordination and / or cooperation is performed by the UTRAN / E-UTRAN / NG-RAN and the core network.

[0017] The communication device 14 may be a user equipment (UE), a very small aperture terminal (VSAT), a low-cost device (e.g., a machine-type communication (MTC) device), a device-to-device (D2D) communication device, a narrowband Internet of Things (IoT) (NB-IoT), a mobile phone, a laptop, a tablet computer, an e-book, a portable computer system, or a combination thereof. Furthermore, the network 12 and the communication device 14 may be considered as a transmitter or a receiver according to the direction (i.e., the transmission direction), e.g., in the case of an uplink (UL), the communication device 14 is the transmitter and the network 12 is the receiver, and in the case of a downlink (DL), the network 12 is the transmitter and the communication device 14 is the receiver.

[0018] 2 is a schematic diagram of a communication device 20 according to an example of the present disclosure. The communication device 20 may be the communication device 14 or the network 12 shown in FIG. 1 , but is not limited thereto herein. The communication device 20 may include at least one processing circuit 200, such as a microprocessor or an application-specific integrated circuit (ASIC), at least one storage device 210, and at least one communication interface device 220. The at least one storage device 210 may be any data storage device capable of storing program code 214 that is accessed and executed by the at least one processing circuit 200. Examples of the at least one storage device 210 include, but are not limited to, a subscriber identity module (SIM), a read-only memory (ROM), a flash memory, a random access memory (RAM), a compact disc read-only memory (CD-ROM), a digital versatile disc ROM (DVD-ROM), a Blu-ray disc ROM (BD-ROM), a magnetic tape, a hard disk, an optical data storage device, a non-volatile storage device, a non-transitory computer-readable medium (e.g., a tangible medium), etc. The at least one communication interface device 220 is preferably at least one transceiver, and is used to transmit and receive signals (eg, data, messages and / or packets) according to the processing results of the at least one processing circuit 200.

[0019] 3 is a flowchart of a process 30 according to an example of the present disclosure. The process 30 may be utilized in a communication device (e.g., communication device 14 of FIG. 1 or communication device 20 of FIG. 2) to handle DL signal reception. The process 30 may be compiled into program code 214 and includes the following steps: Step 300: Start. Step 302: Receive a first configuration from the network to indicate subband non-overlapping full duplex (SBFD) resources, the first configuration indicating a first time period for the SBFD resources and indicating at least one DL subband and UL subband for the SBFD resources. Step 304: Receive a second configuration from the network to indicate periodic DL signal reception, the second configuration indicating a first frequency domain resource for the periodic DL signal reception. Step 306: Perform at least one communication operation with the network according to the first configuration and the second configuration. Step 308: End.

[0020] According to process 30, the communication device receives a first configuration from the network to indicate SBFD resources. The first configuration indicates a first time period for the SBFD resources and indicates at least one DL subband and UL subband for the SBFD resources. The communication device receives a second configuration from the network to indicate periodic DL signal reception. The second configuration indicates first frequency domain resources for the periodic DL signal reception. The communication device then performs at least one communication operation with the network according to the first configuration and the second configuration. In one example, the communication device may perform (e.g., monitor) periodic DL signal reception during the first time period and the first frequency domain resources.

[0021] The implementation of the process 30 is not limited to the above description. The following examples may be applied to implement the process 30.

[0022] In one example, the communication device receives a third configuration from the network to indicate the at least one pattern. In one example, the third configuration comprises (e.g., is) an upper layer configuration. In one example, each of the at least one period of the at least one pattern may be, but is not limited to, 0.5, 0.625, 1, 1.25, 2, 2.5, 5, or 10 milliseconds (ms).

[0023] In one example, the communication device receives a fourth configuration to indicate a bandwidth portion (BWP) configuration. In one example, the BWP configuration indicates a BWP for the communication device. In one example, the communication device performs at least one communication operation with a network according to the first configuration, the second configuration, and the fourth configuration.

[0024] In one example, the communications device receives a fifth configuration from the network, where the fifth configuration comprises at least one of a first slot parameter, at least one monitoring bitmap, a repetition count, a duration, and at least one control resource set (CORESET) identity (ID).

[0025] In one example, the first slot parameter indicates the number of slots for monitoring (e.g., physical downlink control channel (PDCCH) monitoring) configured as a periodicity or offset. In one example, the first slot parameter may be 1, 2, 4, 5, 8, 10, 20, 40, 80, 160, 320, 640, 1280, or 2560 slots, but is not limited thereto herein. In one example, the first slot parameter is greater than the second slot parameter. In one example, the first slot parameter is less than the second slot parameter. In one example, the second slot parameter indicates a periodicity for configuring a slot type (e.g., UL slot, DL slot, flexible slot, and / or SBFD slot).

[0026] In one example, each monitoring bitmap of the at least one monitoring bitmap includes a first plurality of bits. In one example, the first plurality of bits represent (e.g., correspond to) a portion of a slot within a periodicity indicated by a first slot parameter. For example, a first bit of the monitoring bitmap corresponds to a first slot within the slots, a second bit of the monitoring bitmap corresponds to a second slot within the slots, and so on. In one example, a bit length of the monitoring bitmap is no greater than the first slot parameter. In one example, the bit length of the monitoring bitmap is related to a second slot parameter (e.g., the number of slots within the periodicity indicated by the second slot parameter).

[0027] In one example, the communications device determines whether to perform monitoring (e.g., PDCCH monitoring) in a slot according to a monitoring bitmap. In one example, the communications device disables monitoring (e.g., PDCCH monitoring) in a slot in response to a bit in the monitoring bitmap corresponding to the slot being a first value (e.g., “0”). In one example, the communications device disables monitoring (e.g., PDCCH monitoring) in a slot in response to a bit in the monitoring bitmap corresponding to the slot being a second value (e.g., “1”). In one example, the communications device disables monitoring (e.g., PDCCH monitoring) in a slot in response to a bit in the monitoring bitmap corresponding to the slot being a second value (e.g., “1”) and the slot does not overlap with SBFD resources.

[0028] In one example, the at least one monitoring bitmap comprises a first monitoring bitmap and a second monitoring bitmap. In one example, the communication device performs monitoring (e.g., PDCCH monitoring) in even time periods within the periodicity indicated by the first slot parameter in accordance with the first monitoring bitmap. In one example, the communication device performs monitoring (e.g., PDCCH monitoring) in odd time periods within the periodicity indicated by the first slot parameter in accordance with the second monitoring bitmap. That is, in the case of multiple monitoring bitmaps, slots in different time periods within the periodicity indicated by the first slot parameter may be configured in accordance with different monitoring bitmaps. In one example, a first plurality of slots in the even time periods are configured in accordance with a first pattern. In one example, a second plurality of slots in the odd time periods are configured in accordance with a second pattern. In one example, the at least one pattern comprises a first pattern and a second pattern.

[0029] In one example, the repetition count indicates the number of repetitions of the monitoring bitmap within the periodicity indicated by the first slot parameter. In one example, the communication device performs monitoring (e.g., PDCCH monitoring) within the slot according to the monitoring bitmap and the repetition count. In one example, the product of the repetition count and the bit length is not greater than the first slot parameter. In one example, the repetition count is an integer. In one example, the communication device determines the repetition count according to the bit length and the first slot parameter.

[0030] In one example, the duration indicates a third plurality of slots that the search space (SS) lasts (e.g., by periodicity or offset) within the periodicity indicated by the first slot parameter. In one example, the third plurality of slots do not overlap with the SBFD resources. In one example, the third plurality of slots are contiguous slots except for the slots that overlap with the SBFD resources. In one example, the duration number is an integer. In one example, the communication device performs monitoring (e.g., PDCCH monitoring) within the periodicity indicated by the first slot parameter according to the duration in response to the SBFD resources not overlapping with the periodicity indicated by the first slot parameter. In one example, the communication device performs monitoring (e.g., PDCCH monitoring) within the periodicity indicated by the first slot parameter in response to the SBFD resources overlapping with the periodicity indicated by the first slot parameter in accordance with the monitoring bitmap.

[0031] In one example, the duration indicates the number of repetitions of the monitoring bitmap within the periodicity indicated by the first slot parameter. In one example, the communication device performs monitoring within the slot (e.g., PDCCH monitoring) according to the monitoring bitmap and the duration. In one example, the product of the duration and the bit length is not greater than the first slot parameter.

[0032] In one example, each of the at least one CORESET IDs corresponds to a CORESET. In one example, the communication device performs monitoring (e.g., PDCCH monitoring) via a CORESET indicated by one of the at least one CORESET ID. In one example, the at least one CORESET ID is associated with an SS set.

[0033] In one example, the second configuration further indicates second frequency domain resources for periodic DL signal reception. In one example, the communications device receives a periodic DL signal for periodic DL signal reception from the network over the second frequency domain resources in response to the periodic DL signal being within a first time period of the SBFD resources. In one example, in response to the periodic DL signal not being within the first time period of the SBFD resources, the communications device disables receiving a periodic DL signal for periodic DL signal reception from the network over the second frequency domain resources. In one example, in response to the periodic DL signal not being within the first time period of the SBFD resources, the communications device receives a periodic DL signal for periodic DL signal reception from the network over the first frequency domain resources.

[0034] In one example, the second configuration comprises at least one of a first resource bitmap and an adaptation parameter. In one example, the communication device determines first frequency domain resources for a second time period according to the first resource bitmap. In one example, the second time period does not overlap with any SBFD resources. In one example, the SBFD resources comprise at least one DL subband and an UL subband. In one example, the communication device determines first frequency domain resources for the first time period according to at least one of the first resource bitmap and the adaptation parameter. In one example, the first time period overlaps (e.g., completely) with the SBFD resources.

[0035] In one example, the first resource bitmap indicates first frequency domain resources during a second time period. In one example, the first resource bitmap comprises a second plurality of bits. In one example, the second plurality of bits correspond to multiple frequency portions of the BWP, respectively. For example, a first bit of the first resource bitmap corresponds to the lowest frequency portion of the BWP, a second bit of the first resource bitmap corresponds to the second lowest frequency portion of the BWP, and so on. In one example, a bit of the first resource bitmap having a third value (e.g., "0") indicates that the frequency portion of the BWP corresponding to the bit does not overlap with the first frequency domain resources. In one example, a bit of the first resource bitmap having a fourth value (e.g., "1") indicates that the frequency portion of the BWP corresponding to the bit overlaps with the first frequency domain resources. In one example, the communication device disables monitoring (e.g., PDCCH monitoring) on ​​the frequency portion of the BWP in response to the bit of the first resource bitmap corresponding to the frequency portion being the third value. In one example, the communications device performs monitoring (eg, PDCCH monitoring) on ​​a frequency portion of the BWP in response to a bit of the first resource bitmap corresponding to the frequency portion being a fourth value.

[0036] In one example, the adaptation parameters comprise at least one of a second resource bitmap, an offset, a direction indicator, and an adaptation indicator. In one example, the second resource bitmap indicates second frequency domain resources for a first time period. Note that the terms “first resource bitmap” and “first frequency domain resources” in the previous paragraph can be replaced with the terms “second resource bitmap” and “second frequency domain resources,” respectively, and therefore, examples of second resource bitmaps can refer to the previous paragraph and will not be mentioned herein. In one example, the communication device obtains the second resource bitmap from the second configuration. In one example, the communication device generates the second resource bitmap by shifting (e.g., cyclically) bits in the first resource bitmap according to at least one of the offset, the direction indicator, and the adaptation indicator, for example, in response to the second configuration not comprising the second resource bitmap. In one example, the communication device determines second frequency domain resources for a first time period according to the second resource bitmap.

[0037] In one example, the offset indicates a bit offset of the first resource bitmap. In one example, the offset further indicates a shift direction for the bit offset. In one example, the communications device shifts the second plurality of bits in the first resource bitmap in a first direction (e.g., from left to right) (e.g., circularly) in response to the offset being a positive value. In one example, the communications device shifts the second plurality of bits in the first resource bitmap in a second direction (e.g., from right to left) (e.g., circularly) in response to the offset being a negative value.

[0038] In one example, the direction indicator indicates a shift direction of the bit offset. In one example, the direction indicator comprises one bit. In one example, the communications device shifts the second plurality of bits in the first resource bitmap in a third direction (e.g., from right to left) (e.g., cyclically) in response to the direction indicator being a fifth value (e.g., “0”). In one example, the communications device shifts the second plurality of bits in the first resource bitmap in a fourth direction (e.g., from left to right) (e.g., cyclically) in response to the direction indicator being a sixth value (e.g., “1”).

[0039] In one example, the adaptation indicator comprises a third plurality of bits. In one example, a first bit of the adaptation indicator indicates a shift direction for the bit offset. In one example, at least one remaining bit of the adaptation indicator indicates a bit offset. In one example, the communications device shifts the second plurality of bits in the first resource bitmap in a fifth direction (e.g., from right to left) (e.g., cyclically) in response to the adaptation indicator being a seventh value (e.g., “0”). In one example, the communications device shifts the second plurality of bits in the first resource bitmap in a sixth direction (e.g., from left to right) (e.g., cyclically) in response to the adaptation indicator being an eighth value (e.g., “1”).

[0040] In one example, each bit of the first resource bitmap represents (e.g., corresponds to) a first plurality of resource blocks (RBs) (e.g., six RBs of the CORESET). In one example, the RB index of the first RB of the first bit of the first resource bitmap is the smallest RB index in the BWP. In one example, the smallest RB index is a multiple of a ninth value (e.g., 6). For example, the first bit of the first resource bitmap indicates RBs "6x" through "6x+5," the second bit of the first resource bitmap indicates RBs "6(x+1)" through "6(x+1)+5," and so on. In one example, x is an integer. In one example, a bit of the first resource bitmap having a tenth value (e.g., "0") indicates that the frequency portion of the BWP corresponding to the bit does not overlap with the first frequency domain resource. In one example, a bit of the first resource bitmap having an eleventh value (e.g., "1") indicates that the frequency portion of the BWP corresponding to the bit overlaps with the first frequency domain resource. Please note that the terms "first resource bitmap" and "first frequency domain resource" in this paragraph can be replaced with the terms "second resource bitmap" and "second frequency domain resource", respectively.

[0041] In one example, the communications device determines that at least one first RB of the first plurality of RBs is valid with respect to bits of the first resource bitmap in response to the at least one first RB overlapping (e.g., completely) with at least one DL subband and the at least one second RB of the first plurality of RBs overlapping (e.g., completely or partially) with a UL subband. In one example, the communications device determines that the at least one second RB is invalid with respect to bits of the first resource bitmap. Note that the term "first resource bitmap" in this paragraph can be replaced with the term "second resource bitmap."

[0042] In one example, when a monitoring occasion (MO) associated with a CORESET is within a first time period, the communication device determines a first frequency domain resource and / or a second frequency domain resource according to at least one of a first resource bitmap, a position of a UL subband, and a position of a guard band. In one example, the communication device selects a first bit and a second bit from the first resource bitmap and generates a second resource bitmap by shifting (e.g., cyclically) the bits in the first resource bitmap according to bit indexes of the first bit and the second bit. In one example, the first bit is a first bit having a twelfth value (e.g., “1”) in the first resource bitmap, and the second bit is a first bit in the first resource bitmap where all RBs overlap (e.g., completely) with at least one DL subband. In one example, the first bit is a last bit having a thirteenth value (e.g., “1”) in the first resource bitmap, and the second bit is a last bit in the first resource bitmap where all RBs overlap (e.g., completely) with at least one DL subband.

[0043] In one example, the communication device does not expect DL control information to be carried on a portion of the second frequency domain resources. In one example, the communication device disables performing monitoring (e.g., PDCCH monitoring or SS set monitoring) on ​​a portion of the second frequency domain resources. In one example, the portion of the second frequency domain resources does not overlap (e.g., completely) with at least one DL subband.

[0044] In one example, a communication device is configured with a CORESET in a BWP. In one example, the communication device divides the CORESET into a plurality of resource element groups (REGs). In one example, the communication device groups a plurality of REGs into a plurality of REG bundles. In one example, each of the plurality of REG bundles comprises at least one first REG (e.g., two or six REGs). In one example, the plurality of REG bundles do not overlap in the frequency domain. In one example, the communication device groups a plurality of REG bundles into a plurality of control channel elements (CCEs). In one example, each of the plurality of CCEs comprises at least one second REG (e.g., six REGs). In one example, the plurality of CCEs do not overlap with each other in the frequency domain.

[0045] In one example, the communications device determines that a first RB of a first frequency domain resource is valid in response to the first RB overlapping (e.g., completely) with at least one DL subband. In one example, the communications device determines that a second RB of the first frequency domain resource is invalid in response to the second RB overlapping (e.g., completely or partially) with a UL subband. Note that the term "first frequency domain resource" in this paragraph can be replaced with the term "second frequency domain resource."

[0046] In one example, the communications device numbers the plurality of REGs (e.g., in ascending order and / or in a time-prioritized manner) in response to the plurality of REGs (i.e., the CORESET) overlapping (e.g., completely) with the second time period. In one example, the communications device numbers a portion of the plurality of REGs (e.g., the CORESET) in response to the plurality of REGs overlapping (e.g., completely) with the first time period (e.g., completely). In one example, the portion of the plurality of REGs does not include any invalid RBs. That is, the communications device does not number REGs that constitute invalid RBs. In one example, the number of numbered REGs is a multiple of a fourteenth value (e.g., 6). In one example, the communications device disables monitoring (e.g., PDCCH monitoring) on ​​the portion of the numbered REGs in response to the number of numbered REGs not being a multiple of a fourteenth value.

[0047] In one example, the maximum RB index of CORESET in the UL subband is a multiple of a fifteenth value (e.g., 2, 3, or 6). In one example, the minimum RB index of CORESET in the UL subband is a multiple of a fifteenth value (e.g., 2, 3, or 6).

[0048] In one example, the communication device partitions the first frequency domain resource (and / or the second frequency domain resource) according to a size having a second plurality of RBs to generate a plurality of partitions. In one example, the plurality of partitions comprise (e.g., are) a plurality of REGs, a plurality of REG bundles, or a plurality of CCEs, but are not limited thereto herein. In one example, the network sets the size having the second plurality of RBs to the communication device according to a size parameter. In one example, the communication device indicates the size parameter to the network.

[0049] In one example, the communication device performs multiple channel estimations for multiple partitions, respectively. In one example, the communication device determines that at least one third RB in one partition of the multiple partitions that overlaps (e.g., completely) with at least one DL subband is valid. In one example, the communication device determines that at least one fourth RB in the one partition that overlaps (e.g., completely or partially) with a UL subband is invalid in response to the partition simultaneously overlapping at least one DL subband and a UL subband. In one example, the communication device performs channel estimation for a partition with at least one third RB that overlaps (e.g., only) with at least one DL subband.

[0050] In one example, the communications device performs at least two channel estimates for a partition in response to the partition comprising a plurality of non-contiguous RBs. In one example, the plurality of non-contiguous RBs correspond to a plurality of non-contiguous RB indices, respectively. In one example, the communications device performs at least two channel estimates for one partition of the plurality of partitions in response to the partition comprising a plurality of non-contiguous RBs and the communications device being configured with partition parameters. In one example, the network configures the communications device with the partition parameters. In one example, the communications device performs multiple channel estimates for each of a plurality of partitions in response to the communications device not being configured with partition parameters.

[0051] In one example, the multiple partition indices correspond to multiple partitions and are consecutive values. In one example, each RB of the multiple partitions does not overlap (e.g., completely or partially) with an UL subband. In one example, each RB of the multiple partitions overlaps (e.g., completely) with at least one DL subband.

[0052] In one example, the communication device determines that one partition of the plurality of partitions is valid in response to the one partition overlapping (e.g., completely) with at least one DL subband. In one example, the communication device determines that one partition of the plurality of partitions is invalid in response to the one partition simultaneously overlapping (e.g., completely) with at least one DL subband and a UL subband. In one example, the communication device determines that one partition of the plurality of partitions is invalid in response to the partition overlapping (e.g., completely or partially) with a UL subband. In one example, the communication device number (or renumber) at least one valid partition with at least one updated partition index. In one example, the plurality of partitions comprises at least one valid partition. In one example, each RB of the at least one valid partition does not overlap (e.g., completely or partially) with a UL subband. In one example, each RB of the at least one valid partition overlaps (e.g., completely) with at least one DL subband. In one example, the communication device performs at least one channel estimation for the at least one valid partition.

[0053] In one example, the periodic DL signal for periodic DL signal reception comprises (e.g., is associated with) a first plurality of candidate DL signals. In one example, the first plurality of candidate DL signals are associated with different SSs. In one example, the SSs are configured with the same link ID. In one example, the communication device disables receiving (e.g., monitoring) at least one first candidate DL signal from the first plurality of candidate DL signals from the network in response to the at least one first candidate DL signal overlapping (e.g., fully or partially) with an UL subband. In one example, the communication device receives (e.g., monitors) at least one second candidate DL signal from the first plurality of candidate DL signals from the network in response to the at least one second candidate DL signal overlapping (e.g., fully) with at least one DL subband. In one example, the communications device disables combining the at least one first candidate DL signal with the at least one second candidate DL signal to decode the periodic DL signal in response to one of the at least one first candidate DL signal and the at least one second candidate DL signal overlapping (e.g., fully or partially) with an UL subband.

[0054] In one example, a periodic DL signal for periodic DL signal reception is associated with two candidate DL signals. In one example, the two candidate DL signals are each associated with two SSs. In one example, the two SSs are configured with the same link ID. In one example, in response to the two candidate DL signals not overlapping (e.g., completely or partially) with the UL subband, the communication device combines the two candidate DL signals to decode the periodic DL signal and counts three candidate DL signals for the periodic DL signal. In one example, in response to one of the two candidate DL signals not overlapping (e.g., completely or partially) with the UL subband, the communication device disables combining the two candidate DL signals to decode the periodic DL signal and counts one candidate DL signal for the periodic DL signal. In one example, in response to the two candidate DL signals overlapping (e.g., completely or partially) with the UL subband, the communication device counts zero candidate DL signals for the periodic DL signal.

[0055] In one example, the second configuration further indicates a number of candidate DL signals for periodic DL signal reception. In one example, the communication device determines whether a second plurality of candidate DL signals for periodic DL signal reception overlaps with an UL subband. In one example, the communication device selects at least one third candidate DL signal from the second plurality of candidate DL signals that does not overlap (e.g., fully or partially) with an UL subband. In one example, the at least one third candidate DL signal is configured for an aggregation level (AL). In one example, the communication device determines at least one third candidate DL signal to be enabled for performing monitoring (e.g., PDCCH monitoring). In one example, the number of the at least one third candidate DL signal is not greater than the number of candidate DL signals for periodic DL signal reception. In one example, the communication device disables selecting any candidate DL signal from the second plurality of candidate DL signals in response to the second plurality of candidate DL signals overlapping with an UL subband.

[0056] In one example, at least one RB of a valid candidate DL signal (e.g., one candidate DL signal among the at least one third candidate DL signal) overlaps with at least one DL subband. In one example, the code rate of the valid candidate DL signal is not greater than the preconfigured code rate. In one example, the preconfigured code rate is preconfigured by the network.

[0057] In one example, the second configuration further indicates the number of candidate DL signals for periodic DL signal reception. In one example, the periodic DL signals for periodic DL signal reception are associated with a DCI format (e.g., DCI format 2_0). In one example, in response to the number of candidate DL signals being one, the communication device searches for a first candidate DL signal that does not overlap (e.g., fully or partially) with a UL subband for the DCI format. In one example, in response to the number of candidate DL signals being two, the communication device searches for a first candidate DL signal and a second candidate DL signal that do not overlap (e.g., fully or partially) with a UL subband for the DCI format. In one example, each RB associated with the first candidate DL signal and the second candidate DL signal overlaps (e.g., fully) with at least one DL subband.

[0058] In one example, the communications device receives a sixth configuration from the network to indicate a preconfigured code rate. In one example, in response to the code rate of the first frequency domain resource (and / or the second frequency domain resource) overlapping with the at least one DL subband being not greater than the preconfigured code rate, the communications device receives periodic DL signals for periodic DL signal reception from the network. In one example, in response to the code rate of the first frequency domain resource (and / or the second frequency domain resource) overlapping with the at least one DL subband being greater than the preconfigured code rate, the communications device disables receiving periodic DL signals for periodic DL signal reception from the network. In one example, the preconfigured code rate is an AL-specific code rate or an SS set-specific code rate.

[0059] In one example, the communications device disables combining of two candidate DL signals for periodic DL signal reception in response to at least one code rate for at least one of the two candidate DL signals being greater than a preconfigured code rate, where the two candidate DL signals correspond to two different SS sets having the same link ID.

[0060] In one example, the second configuration further indicates a plurality of ALs for periodic DL signal reception. In one example, the communications device receives periodic DL signals for periodic DL signal reception from the network in response to a code rate of the first frequency domain resource (and / or the second frequency domain resource) overlapping with the at least one DL subband being not greater than a minimum AL of the plurality of ALs. In one example, the communications device disables receiving periodic DL signals for periodic DL signal reception from the network in response to a code rate of the first frequency domain resource (and / or the second frequency domain resource) overlapping with the at least one DL subband being greater than a minimum AL of the plurality of ALs.

In one example, the communications device receives a periodic DL signal for periodic DL signal reception from the network in response to the first frequency domain resource (and / or the second frequency domain resource) not overlapping (e.g., fully or partially) with a UL subband. In one example, the communications device disables receiving a periodic DL signal for periodic DL signal reception from the network in response to the first frequency domain resource (and / or the second frequency domain resource) simultaneously overlapping with a UL subband and at least one DL subband and in response to a code rate of the first frequency domain resource (and / or the second frequency domain resource) overlapping with at least one DL subband that is greater than a preconfigured code rate. In one example, the communications device receives a periodic DL signal from a network for periodic DL signal reception in response to a first frequency domain resource (and / or a second frequency domain resource) simultaneously overlapping a UL subband and at least one DL subband, and a code rate of the first frequency domain resource (and / or the second frequency domain resource) overlapping at least one DL subband not greater than a preconfigured code rate.

[0062] In one example, the communications device disables monitoring for periodic DL signal reception (e.g., PDCCH monitoring) on ​​at least one CCE of the first frequency domain resource (and / or the second frequency domain resource) in response to the first frequency domain resource (and / or the second frequency domain resource) simultaneously overlapping with an UL subband and at least one DL subband and overlapping with at least one DL subband with a code rate of the at least one CCE greater than a preconfigured code rate. In one example, the communications device disables monitoring for periodic DL signal reception (e.g., PDCCH monitoring) on ​​at least one CCE of the first frequency domain resource (and / or the second frequency domain resource) in response to the first frequency domain resource (and / or the second frequency domain resource) simultaneously overlapping with an UL subband and at least one DL subband and overlapping with at least one DL subband with a code rate of the at least one CCE not greater than a preconfigured code rate.

[0063] In one example, the communication device counts zero candidate DL signals for periodic DL signal reception after disabling receiving periodic DL signals. In one example, the communication device counts one candidate DL signal for periodic DL signal reception after receiving periodic DL signals. In one example, the communication device counts zero CCEs of the first frequency domain resource (and / or the second frequency domain resource) for monitoring after disabling performing monitoring for periodic DL signal reception in at least one CCE. In one example, the communication device counts at least one CCE of the first frequency domain resource (and / or the second frequency domain resource) for monitoring after performing monitoring for periodic DL signal reception in at least one CCE. In one example, the communication device counts the total number of CCEs of the first frequency domain resource (and / or the second frequency domain resource) for monitoring after performing monitoring for periodic DL signal reception in at least one CCE.

[0064] In one example, the communications device disables monitoring for periodic DL signal reception (e.g., PDCCH monitoring) in an SS set associated with the CORESET in response to the SS set or the CORESET overlapping (e.g., fully or partially) with an UL subband. In one example, the communications device counts zero candidate DL signals for the SS set after disabling monitoring for periodic DL signal reception in the SS set. In one example, the communications device counts zero CCEs for the SS set after disabling monitoring for periodic DL signal reception in the SS set. In one example, the SS set comprises (e.g., has), but is not limited to, a Type 0-PDCCH Common SS (CSS) set, a Type 0A-PDCCH CSS set, a Type 0B-PDCCH CSS set, a Type 1-PDCCH CSS set, a Type 1A-PDCCH CSS set, a Type 2-PDCCH CSS set, a Type 2A-PDCCH CSS, or a Type 3-PDCCH CSS set.

[0069] 5, the communication device performs monitoring in slots SL1, SL4, SL6, and SL9 because the first and fourth bits of the monitoring bitmap M_BM are "1" and the number of repetitions is 2.

The communication device disables monitoring in slots SL2, SL4, and SL6 because the second bit of the monitoring bitmap M_BM is "0" and the number of repetitions is 3. The communication device disables monitoring in slot SL3 because slot SL3 is an SBFD slot. The communication device disables monitoring in slots SL7 to SL8 because slots SL7 to SL8 do not correspond to the monitoring bitmap M_BM.

[0072] 7 is a schematic diagram of a monitor 70 according to an example of the present disclosure. The communication device is configured with a periodicity P1 for configuring slot types for slots SL1-SL10. The periodicity P1 is 10 slots.

[0075] 8, the communication device performs monitoring within the first periodicity P2 (for example, slots SL1 to SL5) according to the duration, because there is no SBFD slot in the first periodicity P2. Specifically, the communication device performs monitoring within slots SL1 to SL2 because slots SL1 to SL2 are not SBFD slots. Since the duration is 2 and the communication device is performing monitoring within slots SL1 to SL2, the communication device disables performing monitoring within slots SL3 to SL5.

[0082] FIG. 11 is a schematic diagram of CORESET resource determination 110 according to an example of the present disclosure. In FIG. 11, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., there is no SBFD slot in time period N_P0. Time period P0 simultaneously overlaps with DL subbands and UL subbands, i.e., there is an SBFD slot in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0083] In the example of Figure 11, a communication device receives a configuration including resource bitmaps R_BM1-R_BM2. Each bit of resource bitmaps R_BM1-R_BM2 corresponds to a frequency portion of a BWP. Resource bitmap R_BM1 indicates CORESET resource C0 in time period N_P0 and is {0,0,0,1,1,1,1,0,0}. Resource bitmap R_BM2 indicates CORESET resource C0 in time period P0 and is {0,0,0,0,0,1,1,1,0}.

[0084] In the example of FIG. 11, the communication device receives a configuration including a resource bitmap R_BM1 and an offset. The resource bitmap R_BM1 is {0,0,0,1,1,1,1,0,0}. The offset indicates the bit offset of the resource bitmap R_BM1 and the shift direction of the bit offset, which is "+2." The "2" indicates that the bits of the resource bitmap R_BM1 are shifted by two bits. The "+" indicates that the bits of the resource bitmap R_BM1 are cyclically shifted from left to right. Therefore, the communication device obtains a resource bitmap R_BM2{0,0,0,0,0,1,1,1,0} according to the resource bitmap R_BM1 and the offset.

[0085] FIG. 12 is a schematic diagram of CORESET resource determination 120 according to an example of the present disclosure. In FIG. 12, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., there is no SBFD slot in time period N_P0. Time period P0 simultaneously overlaps with DL subbands and UL subbands, i.e., there is an SBFD slot in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0086] In the example of Figure 12, the communication device receives a configuration including resource bitmaps R_BM1-R_BM2. Each bit of resource bitmaps R_BM1-R_BM2 corresponds to a frequency portion of a BWP. Resource bitmap R_BM1 indicates CORESET resource C0 in time period N_P0 and is {0,0,0,1,1,1,1,0,0}. Resource bitmap R_BM2 indicates CORESET resource C0 in time period P0 and is {0,1,1,1,1,0,0,0,0,0}.

[0087] In the example of FIG. 12, the communication device receives a configuration including a resource bitmap R_BM1 and an offset. The resource bitmap R_BM1 is {0,0,0,1,1,1,1,0,0}. The offset indicates the bit offset of the resource bitmap R_BM1 and the shift direction of the bit offset, and is "-2". "2" indicates that the bits of the resource bitmap R_BM1 are shifted by two bits. "-" indicates that the bits of the resource bitmap R_BM1 are cyclically shifted from right to left. Therefore, the communication device obtains a resource bitmap R_BM2{0,1,1,1,1,0,0,0,0} according to the resource bitmap R_BM1 and the offset.

[0088] FIG. 13 is a schematic diagram of CORESET resource determination 130 according to an example of the present disclosure. In FIG. 13, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., there is no SBFD slot in time period N_P0. Time period P0 overlaps with two DL subbands and a UL subband simultaneously, i.e., there is an SBFD slot in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0089] In the example of FIG. 13, the communication device receives a configuration including a resource bitmap R_BM1, an offset, and a direction indicator. Each bit of the resource bitmap R_BM1 corresponds to a frequency portion of the BWP. The resource bitmap R_BM1 indicates a CORESET resource C0 in time period N_P0 and is {0,0,0,1,1,1,1,0,0}. The offset is "2," which indicates that the bits of the resource bitmap R_BM1 are shifted by two bits. The direction indicator is "0," which indicates that the bits of the resource bitmap R_BM1 are cyclically shifted from right to left. Thus, the communication device obtains a resource bitmap R_BM2 {0,1,1,1,1,0,0,0,0} according to the resource bitmap R_BM1, the offset, and the direction indicator. The resource bitmap R_BM2 indicates a CORESET resource C0 in time period P0.

[0090] In the example of FIG. 13, the communication device receives a configuration including a resource bitmap R_BM1 and an adaptation indicator. The resource bitmap R_BM1 is {0,0,0,1,1,1,1,0,0}. The adaptation indicator is "010." The first bit "0" of the adaptation indicator indicates that the bits of the resource bitmap R_BM1 are cyclically shifted from right to left. The remaining bits "10" of the adaptation indicator indicate that the bits of the resource bitmap R_BM1 are shifted by two bits. Thus, the communication device obtains a resource bitmap R_BM2{0,1,1,1,1,0,0,0,0} according to the resource bitmap R_BM1 and the adaptation indicator.

[0091] FIG. 14 is a schematic diagram of CORESET resource determination 140 according to an example of the present disclosure.

A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., there is no SBFD slot in time period N_P0. Time period P0 simultaneously overlaps with two DL subbands and a UL subband, i.e., there is an SBFD slot in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0092] In FIG. 14, the communication device receives a configuration including a resource bitmap R_BM1 and an offset. Each bit of the resource bitmap R_BM1 corresponds to a frequency portion of the BWP. The resource bitmap R_BM1 indicates a CORESET resource C0 in time period N_P0 and is {0,0,0,1,1,1,1,1,1}. The offset indicates the bit offset and the shift direction of the bit offset in the resource bitmap R_BM1, which is "+2." The "2" indicates that the bits in the resource bitmap R_BM1 are shifted by two bits. The "+" indicates that the bits in the resource bitmap R_BM1 are cyclically shifted from left to right. Therefore, the communication device obtains a resource bitmap R_BM2 {1,1,0,0,0,1,1,1,1,1} according to the resource bitmap R_BM1 and the offset. The resource bitmap R_BM2 indicates a CORESET resource C0 in time period P0.

[0093] 15 is a schematic diagram of CORESET resource determination 150 according to an example of the present disclosure. In FIG. 15, the horizontal axis represents the time domain T, and the vertical axis represents RB indexes "6x" to "6(x+9)+5" in the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., no SBFD slots exist in time period N_P0. Time period P0 simultaneously overlaps with DL subbands and UL subbands, i.e., an SBFD slot exists in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0094] In FIG. 15, the communication device receives a configuration including a resource bitmap R_BM1. The resource bitmap R_BM1 indicates CORESET resource C0 in time period N_P0 and is {0,0,0,1,1,1,1,0,0}. Each bit of the resource bitmap R_BM1 corresponds to six RBs. The first bit of the resource bitmap R_BM1 corresponds to RBs "6x" to "6x+5," the second bit of the resource bitmap R_BM1 corresponds to RBs "6(x+1)" to "6(x+1)+5," and so on. The communication device selects the fourth and sixth bits of the resource bitmap R_BM1 to determine a bit offset. Specifically, the fourth bit of the resource bitmap R_BM1 is the first bit that is "1" in the resource bitmap R_BM1. The sixth bit of resource bitmap R_BM1 is the first bit where RBs "6(x+5)" to "6(x+5)+5" overlap with the DL subband. Since 6-4=2, the communication device circularly shifts resource bitmap R_BM1 by two bits from left to right to obtain resource bitmap R_BM2{0,0,0,0,0,1,1,1,1,0}. Resource bitmap R_BM2 indicates CORESET resource C0 in period P0.

[0095] FIG. 16 is a schematic diagram of CORESET resource determination 160 according to an example of the present disclosure. In FIG. 16, the horizontal axis represents the time domain T, and the vertical axis represents RB indexes "6x" to "6(x+9)+5" in the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., there is no SBFD slot in time period N_P0. Time period P0 simultaneously overlaps with DL subbands and UL subbands, i.e., there is an SBFD slot in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0096] In FIG. 16, the communication device receives a configuration including a resource bitmap R_BM1. The resource bitmap R_BM1 indicates CORESET resource C0 in time period N_P0 and is {0,0,0,0,1,1,1,1,0,0}. Each bit of the resource bitmap R_BM1 corresponds to six RBs. The first bit of the resource bitmap R_BM1 corresponds to RBs "6x" through "6x+5," the second bit of the resource bitmap R_BM1 corresponds to RBs "6(x+1)" through "6(x+1)+5," and so on. The communication device selects the eighth and fifth bits of the resource bitmap R_BM1 to determine a bit offset. Specifically, the eighth bit of the resource bitmap R_BM1 is the last bit in the resource bitmap R_BM1 that is "1." The fifth bit of resource bitmap R_BM1 is the first bit where RBs "6(x+4)" to "6(x+4)+5" overlap with the DL subband. Since 8-5=3, the communication device circularly shifts resource bitmap R_BM1 by two bits from right to left to obtain resource bitmap R_BM2{0,1,1,1,1,0,0,0,0,0}. Resource bitmap R_BM2 indicates CORESET resource C0 in time period P0.

[0097] FIG. 17 is a schematic diagram of CORESET resource determination 170 according to an example of the present disclosure. In FIG. 17, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with time periods N_P0 and P0. Time period N_P0 overlaps only with DL subbands, i.e., there is no SBFD slot in time period N_P0. Time period P0 simultaneously overlaps with DL subbands and UL subbands, i.e., there is an SBFD slot in time period P0. DL subbands are shown as mesh blocks, and UL subbands are shown as slash blocks.

[0098] 17, the communication device divides CORESET resource C0 into 12 REGs. In the example of FIG. 17, all REGs of CORESET resource C0 overlap with the DL subband in time period N_P0, so the communication device numbers the 12 REGs as REG0 to REG12 and performs monitoring via REGREG0 to REG12 in time period N_P0. In the example of FIG. 17, some REGs (e.g., the four lowest REGs) of CORESET resource C0 overlap with the UL subband in time period P0, so the communication device ignores the four lowest REGs and numbers the remaining REGs that overlap with the DL subband as REG0 to REG8. Then, because the number of REGREG0 to REG8 is not a multiple of 6, the communication device performs monitoring via six REGs of REGREG0 to REG8 in time period P0.

[0099] FIG. 18 is a schematic diagram of CORESET resource determination 180 according to an example of the present disclosure. In FIG. 18, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with a time period P0. The time period P0 simultaneously overlaps two DL subbands and an UL subband, i.e., an SBFD slot exists within the time period P0. The DL subbands are shown as mesh blocks, and the UL subbands are shown as slash blocks.

[0100] In FIG. 18, the communication device divides CORESET resource C0 into 36 REGs. The communication device ignores some REGs that overlap with the UL subband and numbers the remaining REGs that overlap with the DL subband as REG1 to REG24. Every sixth numbered REG is grouped into a REG bundle. REGs REG1 to REG6 are grouped into REG bundle REG_B1, REGs REG7 to REG12 are grouped into REG bundle REG_B2, and so on. Therefore, for REG bundles REG_B1, REG_B2, and REG_B4, the communication device performs channel estimation for each REG bundle. For REG bundle REG_B3, REGs REG13 to REG18 are discontinuous REGs, so the communication device performs one channel estimation on REGs REG13 to REG16 and the other channel estimation on REGs REG17 to REG18.

[0101] FIG. 19 is a schematic diagram of CORESET resource determination 190 according to an example of the present disclosure. In FIG. 19, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with a time period P0. The time period P0 overlaps two DL subbands and an UL subband simultaneously, i.e., an SBFD slot exists within the time period P0. The DL subbands are shown as mesh blocks, and the UL subbands are shown as slash blocks.

[0102] In FIG. 19, the communication device divides CORESET resource C0 into 36 REGs. The communication device ignores some REGs that overlap with UL subbands and numbers the remaining REGs that overlap with DL subbands as REG1 to REG24. Every third numbered REG is grouped into a REG bundle. REGs REG1 to REG2 are grouped into REG bundle REG_B1, REGs REG3 to REG4 are grouped into REG bundle REG_B2, and so on. Thus, for REG bundles REG_B1 to REG_B12, the communication device performs channel estimation for each REG bundle.

[0103] FIG. 20 is a schematic diagram of CORESET resource determination 200 according to an example of the present disclosure. In FIG. 20, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with a time period P0. The time period P0 simultaneously overlaps two DL subbands and an UL subband, i.e., an SBFD slot exists within the time period P0. The DL subbands are shown as mesh blocks, and the UL subbands are shown as slash blocks.

[0104] In FIG. 20, the communication device divides CORESET resource C0 into 36 REGs and numbers all of the REGs as REG1 to REG36. Every sixth numbered REG is grouped into a REG bundle. REGs REG1 to REG6 are grouped into REG bundle REG_B1, REGs REG7 to REG12 are grouped into REG bundle REG_B2, and so on. Because REG bundles REG_B1, REG_B2, and REG_B6 completely overlap with the DL subband, the communication device determines that REG bundles REG_B1, REG_B2, and REG_B6 are valid. Because REG bundles REG_B3 to REG_B5 completely or partially overlap with the UL subband, the communication device determines that REG bundles REG_B3 to REG_B5 are invalid. Therefore, the communication device renumbers the valid REG bundles REG_B1, REG_B2, and REG_B6 into REG bundles U_REG_B1 to U_REG_B3. For REG bundles U_REG_B1-U_REG_B3, the communication device performs channel estimation for each REG bundle. Note that the terms "REG bundles REG_B1 to REG_B6" and "REG bundles U_REG_B1 to U_REG_B3" in FIG. 20 can be replaced with the terms "CCEs CCE0 to CCE6" and "CCEs U_CCE0 to U_CCE6," respectively.

[0105] FIG. 21 is a schematic diagram of candidate DL signal reception 210 according to an example of the present disclosure. In FIG. 21, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. A communication device is configured with a BWP BWP0 for performing communication operations, and further configured with a time period P0. The time period P0 overlaps simultaneously with DL subbands and UL subbands, i.e., there is an SBFD slot in time period P0. The DL subbands are shown as mesh blocks, and the UL subbands are shown as slash blocks. A CORESET resource C0 comprises two candidate DL signals C_DL_SG1-C_DL_SG2 for periodic DL signals. The candidate DL signals C_DL_SG1-C_DL_SG2 are associated with different SSs having the same link ID.

[0106] In the example of FIG. 21 , the communication device receives candidate DL signal C_DL_SG1 from the network because candidate DL signal C_DL_SG1 overlaps with the DL subband. In the example of FIG. 21 , the communication device disables receiving candidate DL signal C_DL_SG2 from the network because candidate DL signal C_DL_SG2 partially overlaps with the UL subband. In the example of FIG. 21 , the communication device disables receiving candidate DL signal C_DL_SG2 from the network because the code rate of candidate DL signal C_DL_SG2 is greater than the preconfigured code rate. In the example of FIG. 21 , the communication device receives candidate DL signal C_DL_SG2 from the network because the code rate of candidate DL signal C_DL_SG2 is not greater than the preconfigured code rate.

[0107] 22 is a flowchart of a process 220 according to an example of the present disclosure. The process 220 may be utilized in a communication device (e.g., the communication device 14 of FIG. 1 or the communication device 20 of FIG. 2) to count the number of candidate DL signals for a periodic DL signal. The process 220 may be compiled into the program code 214 and includes the following steps: Step 2200: Start. Step 2202: Determine to receive a first candidate DL signal and a second candidate DL signal for the periodic DL signal from the network, where the first candidate DL signal and the second candidate DL signal are associated with different SSs having the same link ID. Step 2204: Does the first candidate DL signal overlap (e.g., completely or partially) with the UL subband? Does the second candidate DL signal overlap (e.g., completely or partially) with the UL subband? If both are "yes," execute step 2206. If one is "yes" and the other is "no," execute step 2208. If both are "no," execute step 2210. Step 2206: Count zero candidate DL signals for the periodic DL signal, and perform step 2212. Step 2208: Disable combining the first candidate DL signal with the second candidate DL signal to decode the periodic DL signal, and count one candidate DL signal for the periodic DL signal, and perform step 2212. Step 2210: Combine the first candidate DL signal and the second candidate DL signal to decode the periodic DL signal, and count three candidate DL signals for the periodic DL signal. Step 2212: End.

[0108] 23 is a flowchart of a process 230 according to an example of the present disclosure. The process 230 may be utilized in a communication device (e.g., the communication device 14 of FIG. 1 or the communication device 20 of FIG. 2) to determine the validity of a candidate DL signal relative to a periodic DL signal. The process 230 may be compiled into the program code 214 and includes the following steps: Step 2300: Start. Step 2302: Decide to perform monitoring of periodic DL signals in the AL and CORESET with some candidate DL signals. Step 2304: Configure a number parameter, which is the number of candidate DL signals. Step 2306: Select a candidate DL signal having an index from the candidate DL signals, where the index is the smallest index among the indexes of the candidate DL signals. Step 2308: Is the candidate DL signal with index valid? If yes, perform step 2310. If no, perform step 2314. Step 2310: Is the index equal to the number parameter minus one? If yes, perform step 2318. If no, perform step 2312. Step 2312: The index is increased by 1, and step 2308 is executed. Step 2314: Is the index equal to the number of CCEs in the CORESET divided by AL? If yes, perform step 2318. If no, perform step 2316. Step 2316: The index and number parameters are increased by 1, and step 2308 is executed. Step 2318: End.

[0109] FIG. 24 is a schematic diagram of candidate DL signal reception 240 according to an example of the present disclosure. In FIG. 24, the horizontal axis represents the time domain T, and the vertical axis represents the frequency domain F. The communication device is configured with a BWP BWP0 for performing communication operations and further configured with a time period P0. The time period P0 overlaps simultaneously with DL subbands and UL subbands, i.e., an SBFD slot exists in time period P0. The DL subbands are shown as mesh blocks, and the UL subbands are shown as slash blocks. CORESET resource C0 comprises four candidate DL signals C_DL_SG1 to C_DL_SG4 for periodic DL signals. The communication device is configured to receive DCI format 2_0 from the network and to receive one candidate DL signal for the periodic DL signal according to DCI format 2_0.

[0110] In the example of Figure 24, the communication device disables receiving candidate DL signals C_DL_SG1 to C_DL_SG2 from the network because they completely or partially overlap with the UL subband. The communication device receives candidate DL signal C_DL_SG3 from the network because the candidate DL signal C_DL_SG3 does not overlap with the UL subband. The communication device disables receiving candidate DL signal C_DL_SG4 from the network because it has received one candidate DL signal (i.e., candidate DL signal C_DL_SG3) from the network.

[0111] In the example of Figure 24, the communication device disables receiving candidate DL signal C_DL_SG1 from the network because candidate DL signal C_DL_SG1 completely overlaps the UL subband. The communication device receives candidate DL signal C_DL_SG2 from the network because the code rate of candidate DL signal C_DL_SG2 is not greater than the preconfigured code rate. The communication device disables receiving candidate DL signals C_DL_SG3 to C_DL_SG4 from the network because it has received one candidate DL signal (i.e., candidate DL signal C_DL_SG2) from the network.

[0112] In the example of Figure 24, the communication device disables receiving candidate DL signal C_DL_SG1 from the network because candidate DL signal C_DL_SG1 completely overlaps with the UL subband.

[0113] 25 is a flowchart of a process 250 according to an example of the present disclosure. The process 250 may be utilized in a communication device (e.g., the network 12 of FIG. 1 or the communication device 20 of FIG. 2) to configure DL signal reception. The process 250 may be compiled into the program code 214 and includes the following steps: Step 2500: Start. Step 2502: Send a first configuration to the communication device to indicate SBFD resources, where the first configuration indicates a first time period for the SBFD resources and indicates at least one DL subband and UL subband for the SBFD resources. Step 2504: Send a second configuration to the communication device to indicate periodic DL signal reception, the second configuration indicating a first frequency domain resource for periodic DL signal reception. Step 2506: Perform at least one communication operation with the communication device according to the first configuration and the second configuration. Step 2508: End.

[0114] According to process 250, the network transmits a first configuration to the communication device to indicate SBFD resources. The first configuration indicates a first time period for the SBFD resources and indicates at least one DL subband and UL subband for the SBFD resources. The network transmits a second configuration to the communication device to indicate periodic DL signal reception. The second configuration indicates first frequency domain resources for periodic DL signal reception. The network then performs at least one communication operation with the communication device according to the first configuration and the second configuration. In one example, the communication device may perform (e.g., monitor) periodic DL signal reception in the first time period and the first frequency domain resources.

[0115] The implementation of the process 250 is not limited to the above description. The following examples may be applied to implement the process 250.

[0116] In one example, the network transmits a third configuration to the communication device to indicate the at least one pattern. In one example, the network transmits a fourth configuration to the communication device to indicate the BWP configuration. In one example, the network performs at least one communication operation with the communication device according to the first configuration, the second configuration, and the third configuration.
