Description

Technical Field

[0001] The present invention relates to a method and a communication device for a wireless communication system, and in particular to a method and a communication device for processing communication with a serving cell. Background Art

[0002] In order to improve the Universal Mobile Telecommunications System (UMTS), the 3rd Generation Partnership Project (3GPP) has developed a Long Term Evolution (LTE) system with better performance, which supports the 3rd Generation Partnership Project's eighth release (3GPP Rel-8) standard and / or the 3rd Generation Partnership Project's ninth release (3GPP Rel-9) standard to meet the increasing needs of users.

[0003] LTE-Advanced (LTE-A) is an evolution of LTE. The goal of LTE-Advanced is to provide fast power state transition, enhance the edge performance of evolved Node-B (eNB), and increase peak data rate and throughput. It includes advanced technologies such as carrier aggregation and uplink (UL) multiple-input multiple-output (UL MIMO).

[0004] The next generation radio access network (NG-RAN) is developed to enhance the advanced long-term evolution system, which supports the 3rd Generation Partnership Project Release 15 (3GPP Rel-15) to the 3rd Generation Partnership Project Release 19 (3GPP Rel-19) standards. The next generation radio access network includes one or more next generation Node-B (gNB) and has wider operating frequency bands, different numerologies in different frequency ranges, massive multi-input multi-output (MIMO) systems, advanced channel coding and other features.

[0005] As the demand for the use of communication devices increases, the number of signals (such as data, information and / or packets) transmitted between the communication device and the network end in the service cell also increases. The network end can set the communication device to perform operations of different transmission directions within a time interval (such as a time slot or a symbol) to meet the use demand of the communication device, which causes the communication device to switch the transmission direction multiple times within the time interval. However, the communication device cannot perform more than one direction switch within the time interval, resulting in the communication device being unable to perform operations with the network end. Therefore, how to handle the communication between the communication device and the network end in the service cell that includes operations of different transmission directions is a problem that needs to be solved urgently. Summary of the invention

[0006] One of the objectives of the present invention is to provide a method and a communication device thereof for processing communication with a serving cell to solve the above-mentioned problem.

The invention relates to a method for transmitting the plurality of operations of a network to a plurality of regions; receiving at least one indicator for a plurality of operations in a time slot from the network end; and determining whether to execute at least one operation of the plurality of operations in the time slot; wherein the plurality of operations overlap with at least one special symbol of the special symbol set; wherein the plurality of operations include at least one downlink reception and at least one uplink transmission.

[0008] The present invention also discloses a communication device for processing a communication with a serving cell, comprising at least one storage device and at least one processing circuit coupled to the at least one storage device. The at least one storage device is configured to store instructions, and the at least one processing circuit is configured to execute the following instructions stored in the at least one storage device: receiving a first configuration from a network end, wherein the first configuration indicates at least one of a downlink (DL) symbol set, a flexible symbol set, and an uplink (UL) symbol set within a time period; receiving a second configuration for the serving cell from the network end, wherein the second configuration indicates a special symbol set in at least one of the downlink symbol set and the flexible symbol set, and the special symbol set includes at least one of different frequency regions (frequency zones) of the serving cell. The invention relates to a method for transmitting the plurality of operations of a network to a plurality of regions; receiving at least one indicator for a plurality of operations in a time slot from the network end; and determining whether to execute at least one operation of the plurality of operations in the time slot; wherein the plurality of operations overlap with at least one special symbol of the special symbol set; wherein the plurality of operations include at least one downlink reception and at least one uplink transmission.

[0009] The present invention also discloses a method for a network end to process a communication with a communication device, comprising: transmitting a first configuration to the communication device, wherein the first configuration indicates at least one of a downlink (DL) symbol set, a flexible symbol set, and an uplink (UL) symbol set within a time period; transmitting a second configuration for the service cell to the communication device, wherein the second configuration indicates a special symbol set in at least one of the downlink symbol set and the flexible symbol set, and the special symbol set includes symbols in different frequency regions of the service cell. The invention relates to a method for transmitting a plurality of operations in a time slot to the communication device; wherein the plurality of operations overlap with at least one special symbol of the special symbol set; and wherein the plurality of operations include at least one downlink reception and at least one uplink transmission.

[0010] According to the above, the present invention provides a method and a communication device for processing communication with a serving cell. According to the present invention, the number of switching points within a time interval is reduced. The communication device does not need to switch the transmission direction multiple times within the time interval. Therefore, the problem of processing communication between the communication device and the network end can be solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Figure 1 1 is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention, which is briefly composed of a network 12 and a plurality of communication devices 14. The wireless communication system 10 can support a time-division duplexing (TDD) mode, a frequency-division duplexing (FDD) mode, a combined operation mode of time-division duplexing and frequency-division duplexing, a non-terrestrial network (NTN) mode or a licensed-assisted access (LAA) mode. That is, the network 12 and the communication device 14 can communicate with each other through a frequency-division duplexing carrier, a time-division duplexing carrier, a licensed carrier (licensed serving cell) and / or an unlicensed carrier (or unlicensed serving cell). In addition, the wireless communication system 10 can support carrier aggregation. That is, the network 12 and the communication device 14 can communicate with each other through a plurality of serving cells (e.g., a plurality of serving carriers) including a primary cell (e.g., a primary component carrier) and one or more secondary cells (e.g., a secondary component carrier).

[0046] exist Figure 1In the figure, the network 12 and the communication device 14 are used to illustrate the architecture of the wireless communication system 10. In the Universal Mobile Telecommunications System (UMTS), the network 12 may be a Universal Terrestrial Radio Access Network (UTRAN), which includes at least one Node-B (NB). In one embodiment, in a Long Term Evolution (LTE) system, an LTE-advanced (LTE-A) system, and an evolved version of the LTE-A system, the network 12 may be an evolved universal terrestrial radio access network (E-UTRAN), which includes at least one evolved NB (eNB) and / or at least one relay node. In one embodiment, the network 12 may be a next generation radio access network (NG-RAN), which includes at least one next generation Node-B (gNB) and / or at least one fifth generation (5G) base station (BS). In one embodiment, the next generation base station or fifth generation base station of the network 12 may include a non-terrestrial gateway (NTN Gateway) and a non-terrestrial payload (NTN payload). In one embodiment, the network 12 may be any base station that complies with a specific communication standard to communicate with the communication device 14.

[0047] New Radio (NR) is a standard defined for the fifth generation system (or fifth generation network) to provide a unified air interface with better performance. The next generation base stations are deployed to implement the fifth generation system, which supports advanced features such as enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), and massive machine type communications (mMTC). Enhanced mobile broadband provides broadband services with greater bandwidth and low / medium latency. Ultra reliable low latency communications provides higher reliability and low latency for applications (such as end-to-end communications). Examples of applications include industrial Internet, smart grid, infrastructure protection, remote surgery, and intelligent transportation system (ITS). Massive machine type communications can support the fifth generation system's Internet of Things (IoT), which includes billions of connected devices and / or sensors.

[0048] In addition, the network end 12 may also include at least one of a Universal Terrestrial Universal Radio Access Network / Evolved Universal Terrestrial Universal Radio Access Network / Next Generation Radio Access Network and a core network, wherein the core network includes 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 Networks (SON) server, a Radio Network Controller (RNC), an Access and Mobility Management Function (AMF), a Session Management Function (SMF), a User Plane Function (UPF) and / or an Authentication Server Function (AUSF). In one embodiment, after the network end 12 receives the information transmitted by the communication device 14, the information may be processed only by the UTRAN / EUTRAN / NGRAN, and a decision corresponding to the information may be made in the UTRAN / EUTRAN / NGRAN. In one embodiment, the UTRAN / EUTRAN / NGRAN may forward the information to the core network, and after the core network processes the information, a decision corresponding to the information may be made in the core network. In one embodiment, the information may be processed by the UTRAN / EUTRAN / NGRAN and the core network, and a decision may be made after the UTRAN / EUTRAN / NGRAN and the core network perform coordination and / or cooperation.

[0049] 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 narrow-band internet of things (NB-IoT), a mobile phone, a laptop, a tablet, an e-book, a portable computer system, or a combination of the above devices. In addition, according to the transmission direction, the network end 12 and the communication device 14 may be respectively regarded as a transmitting end or a receiving end. For example, for an uplink (UL), the communication device 14 is a transmitting end and the network end 12 is a receiving end; for a downlink (DL), the network end 12 is a transmitting end and the communication device 14 is a receiving end.

The at least one communication interface device 220 may include at least one radio transceiver, which is used to transmit and receive signals (e.g., data, information, and / or packets) according to the processing result of the at least one processing circuit 200.

[0051] Figure 3 FIG. 3 is a flow chart of a process 30 according to an embodiment of the present invention. The process 30 is used for a communication device (eg Figure 1 The communication device 14 or Figure 2 A communication device 20) is provided to handle communication with the serving cell.

[0052] The process 30 can be compiled into the program code 214 and includes the following steps:

[0053] Step 300: Start.

[0054] Step 302: Receive a first configuration from a network, wherein the first configuration indicates at least one of a downlink (DL) symbol set, a flexible symbol set, and an uplink (UL) symbol set within a time period.

[0055] Step 304: Receive a second configuration for the serving cell from the network, wherein the second configuration indicates a special symbol set in at least one of the downlink symbol set and the flexible symbol set, and the special symbol set includes at least one downlink sub-band and at least one uplink sub-band in different frequency regions of the serving cell.

[0056] Step 306: Receive at least one indicator for a plurality of operations in a time slot from the network.

[0057] Step 308: Determine whether to execute at least one of the plurality of operations in the time slot.

[0058] Step 310: End.

[0059] According to process 30, the communication device receives a first configuration (e.g., TDD-UL-DL-ConfigCommon) from the network. The first configuration indicates at least one of a downlink symbol set, a flexible symbol set, and an uplink symbol set within a time interval (e.g., at least one symbol or a radio frame). The communication device receives a second configuration for a serving cell from the network. The second configuration indicates a special symbol set in at least one of the downlink symbol set and the flexible symbol set, and the special symbol set includes at least one downlink sub-band and at least one uplink sub-band in different frequency regions of the serving cell. The communication device receives at least one indicator for multiple operations in a time slot from the network. Then, (e.g., based on at least one of the first configuration, the second configuration, and the at least one indicator), the communication device determines whether to execute at least one of the multiple operations in the time slot. That is, the communication device does not execute (e.g., discards) part of the operations of the multiple operations to avoid multiple switching of transmission directions in a time slot. Therefore, the communication between the communication device and the network can be performed normally.

[0060] There are many ways to implement process 30, which are not limited to the above. The following embodiments can be used for process 30.

[0061] In one embodiment, multiple operations overlap with at least one special symbol of the special symbol set. In one embodiment, the multiple operations include at least one downlink reception and at least one uplink transmission. In one embodiment, the time slot includes multiple symbols. In one embodiment, the multiple symbols are set by at least one of the first configuration and the second configuration. In one embodiment, the communication device transmits information to the network. In one embodiment, the information indicates whether the communication device supports more than one switch point in a time slot. In one embodiment, the switch point indicates a direction switch (e.g., transmission-to-reception (TX-RX) switch or reception-to-transmission (RX-TX) switch).

[0062] In one embodiment, the transmission power (power) of the uplink transmission for at least one uplink transmission is determined (e.g., by a communication device) based on first power information set by a network. In one embodiment, the uplink transmission of at least one uplink transmission is set with first power information and second power information. In one embodiment, the first power information corresponds to a special symbol of a special symbol set, and the second power information corresponds to an uplink symbol of an uplink symbol set.

In one embodiment, an uplink transmission of at least one uplink transmission is set with first spatial relation information and second spatial relation information. In one embodiment, the first spatial relation information corresponds to a special symbol of a special symbol set, and the second spatial relation information corresponds to an uplink symbol of an uplink symbol set. In one embodiment, the first spatial relation information includes a first spatial relation information identification (identity module, ID). In one embodiment, the second spatial relation information includes a second spatial relation information identification. In one embodiment, the first spatial relation information includes a first reference signal (reference signal, RS) (e.g., a synchronization signal block (SSB) index, a channel state information reference signal (CSI-RS) index, or a sounding reference signal (SRS)). In one embodiment, the second spatial relation information includes a second reference signal (e.g., a synchronization signal block index, a channel state information reference signal, or a sounding reference signal).

[0064] In one embodiment, the number of physical resource blocks (PRBs) for uplink transmission of at least one uplink transmission is determined by (e.g., a communication device) according to a first coding rate. In one embodiment, the uplink transmission of at least one uplink transmission is set with a first coding rate and a second coding rate. In one embodiment, the first coding rate corresponds to a special symbol of a special symbol set, and the second coding rate corresponds to an uplink symbol of an uplink symbol set. In one embodiment, the communication device is set with a power offset. In one embodiment, according to the power offset, in the special symbol of the special symbol set, the communication device performs the uplink transmission of at least one uplink transmission.

[0065] In one embodiment, the communication device determines an uplink resource (e.g., in at least one uplink sub-band) based on at least one of a resource configuration and a starting physical resource block. In one embodiment, on the uplink resource, in a special symbol of a special symbol set, the communication device (e.g., with a network end) performs an uplink transmission of at least one uplink transmission. In one embodiment, a first number of physical resource blocks of the uplink resource is the same as a second number of physical resource blocks of the uplink transmission for the at least one uplink transmission, and the uplink transmission does not overlap with the at least one special symbol. In one embodiment, the starting physical resource block is determined based on at least one of an offset, a resource configuration, a downlink control information (DL control information, DCI) and a higher-layer signal (e.g., a radio resource control (RRC) signal), and the offset indicates a frequency domain resource set. In one embodiment, the offset indicates a frequency domain resource set (e.g., the number of at least one physical resource blocks). In one embodiment, the offset is selected from a candidate offset set set by a higher-layer signal. In one embodiment, the offset is an exclusive offset for an uplink transmission of at least one uplink transmission set by a higher layer signal. In one embodiment, the resource configuration is set for an uplink transmission of at least one uplink transmission. In one embodiment, the starting physical resource block is indicated for an uplink transmission of at least one uplink transmission.

In one embodiment, the starting physical resource block is exclusive to at least one special symbol. In one embodiment, the uplink transmission of at least one uplink transmission is a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0066] In one embodiment, a communication device (e.g., with a network end) performs an uplink transmission of at least one uplink transmission in a special symbol of a special symbol set, using a portion of resources in at least one uplink sub-band in response to the resources overlapping with at least one downlink sub-band in the special symbol. That is, the uplink transmission of at least one uplink transmission is not performed through the remaining portion of resources in at least one downlink sub-band. In one embodiment, if the first physical resource block of the resources for the uplink transmission of at least one uplink transmission overlaps with at least one downlink sub-band, the communication device determines that the first physical resource block of the uplink transmission used to perform the at least one uplink transmission is the first physical resource block of the at least one uplink sub-band. In one embodiment, if the last physical resource block of the resources for the uplink transmission of at least one uplink transmission overlaps with at least one downlink sub-band, the communication device determines that the last physical resource block of the uplink transmission used to perform the at least one uplink transmission is the last physical resource block of the at least one uplink sub-band.

In one embodiment, the first indicator indicates at least one direction used for a time slot (e.g., a special symbol set in the time slot), and the at least one direction includes at least one of "downlink", "uplink" and "flexible". In one embodiment, the first indicator provides the direction of each special symbol of the special symbol set in the time slot. In one embodiment, the first indicator is included in at least one of a downlink control message, a medium access control (MAC) control element (CE) and a radio resource control signal.

In one embodiment, at least one direction used for the time slot is at least one fixed direction (e.g., uplink and / or downlink).

[0068] In one embodiment, in a first portion of a timeslot, a communication device (e.g., with a network) performs a first operation of a plurality of operations in response to the first operation being an uplink transmission and the first indicator indicating "uplink" for the first portion of the timeslot. In one embodiment, in a second portion of the timeslot, a communication device (e.g., with a network) performs a second operation of a plurality of operations in response to the second operation being a downlink reception and the first indicator indicating "downlink" for the second portion of the timeslot. That is, when the direction for the operation is the same as the direction indicated by the first indicator for a portion of the timeslot, the communication device performs the operations of the plurality of operations in a portion of the timeslot.

[0069] In one embodiment, in a third portion of the time slot, the communication device disables (e.g., with the network) performing a third operation of the plurality of operations in response to the third operation being an uplink transmission and the first indicator indicating "downlink" for at least one first symbol of the third portion of the time slot. In one embodiment, in a fourth portion of the time slot, the communication device disables (e.g., with the network) performing a fourth operation of the plurality of operations in response to the fourth operation being a downlink reception and the first indicator indicating "uplink" for at least one second symbol of the fourth portion of the time slot. That is, the communication device disables performing the operations of the plurality of operations in a portion of the time slot when the direction for the operation is different from the direction for the portion of the time slot indicated by the first indicator.

That is, when the operation is triggered by a signal other than the downlink control information (e.g., a higher layer signal) and the first indicator indicates "flexibility" for a part of the time slot, the communication device prohibits the execution of the operations of the plurality of operations in the part of the time slot.

[0071] In one embodiment, in a sixth portion of the time slot, the communication device (e.g., with the network) performs a sixth operation of a plurality of operations in response to the sixth operation being an uplink transmission and the first direction of the sixth portion of the time slot being not "downlink". In one embodiment, the first direction is a fixed (or default) direction, or is determined by a higher layer configuration. In one embodiment, the fixed (or default) direction is determined according to a (default) capability for the communication device. In one embodiment, the higher layer configuration may be the first configuration or a UE specific UL-DL configuration, but is not limited thereto. In one embodiment, in a seventh portion of the time slot, the communication device (e.g., with the network) performs a seventh operation of a plurality of operations in response to the seventh operation being a downlink reception and the second direction of the seventh portion of the time slot being not "uplink". In one embodiment, the second direction is a fixed (or default) direction, or is determined by a higher layer configuration. That is, when the direction for the operation does not conflict with the direction for a portion of the time slot, the communication device performs the operations of the plurality of operations in a portion of the time slot.

[0072] In one embodiment, the communication device prohibits (e.g., with the network) from performing an eighth operation of the plurality of operations in response to the eighth operation being indicated (or triggered) by a higher-level configuration. In one embodiment, the communication device does not receive (e.g., is configured to receive but misses, is not expected to receive, is prohibited from receiving, or is not configured to receive by the network) a second indicator from the network. In one embodiment, the second indicator indicates at least one direction used for the time slot, and the at least one direction includes at least one of "downlink", "uplink" and "flexibility". In one embodiment, the higher-level configuration includes (e.g., is) a time-division duplex uplink-downlink configuration (e.g., a first configuration or a user-end-specific uplink-downlink configuration). In one embodiment, the second indicator is the same as the first indicator. In one embodiment, the second indicator is different from the first indicator.

[0073] In one embodiment, the communication device determines multiple priorities for multiple operations in response to more than one switching point in a time slot, or in response to multiple operations with different directions overlapping in a time interval. In one embodiment, the multiple priorities correspond to the multiple operations. In one embodiment, the communication device does not have the ability to perform more than one direction switch in a time slot. In other words, the communication device is not able to switch the transmission direction multiple times in a time slot.

[0074] In one embodiment, the communication device does not receive (e.g., is configured to receive but lost, is not expected to receive, is prohibited to receive, or is not configured to receive) a third indicator from the network. In one embodiment, the third indicator indicates at least one direction used for the time slot, and the at least one direction includes at least one of "downlink", "uplink" and "flexible". In one embodiment, the third indicator is the same as the first indicator. In one embodiment, the third indicator is different from the first indicator. In one embodiment, the tenth operation of the plurality of operations is downlink reception other than semi-persistent scheduling physical DL shared channel (SPS-PDSCH), in response to the eleventh operation of the plurality of operations overlapping with the tenth operation being configure grant physical uplink shared channel (CG-PUSCH).

[0075] In one embodiment, the communication device determines a plurality of priorities based on a plurality of priority indexes. In one embodiment, the plurality of priority indexes correspond to a plurality of operations, respectively. In one embodiment, a priority index having a first value represents a high priority. In one embodiment, a priority index having a second value represents a low priority. That is, the first value has a higher priority than the second value.

In one embodiment, according to the control resource set, in the special symbol, the communication device monitors the physical downlink control channel. In one embodiment, the special symbol is a special symbol of the special symbol set.

[0085] In one embodiment, the communication device (e.g., and the network end) does not perform (e.g., discards) a 30th operation of the plurality of operations in response to the 30th operation overlapping with a 31st operation of the plurality of operations in a time interval. In one embodiment, the 30th operation is a third uplink transmission including a first set grant physical uplink shared channel, and the first set grant physical uplink shared channel is configured with type A repetition. Type A repetition means that the repetitions for the first set grant physical uplink shared channel are transmitted in different time slots / symbols. In one embodiment, the 31st operation is a third downlink reception including a third physical downlink shared channel (e.g., a semi-statically scheduled physical downlink shared channel) and is not triggered by a downlink control message. In one embodiment, the fifth priority of the first set grant physical uplink shared channel is the same as the sixth priority of the fifth physical uplink control channel used to transmit a fifth hybrid automatic repeat request acknowledgment of the third physical downlink shared channel. In one embodiment, the 31st operation does not overlap with at least one uplink sub-band.

[0086] In one embodiment, the communication device (e.g., and the network end) does not perform (e.g., discards) a 32nd operation of the plurality of operations in response to the 32nd operation overlapping with a 33rd operation of the plurality of operations in a time interval. In one embodiment, the 32nd operation is a fourth downlink reception including a fourth physical downlink shared channel (e.g., a semi-statically scheduled physical downlink shared channel) and is not triggered by a downlink control message. In one embodiment, the 33rd operation is a fourth uplink transmission including a second set grant physical uplink shared channel, and the second set grant physical uplink shared channel is configured with type B repetition. Type B repetition means that at least two repetitions for the second set grant physical uplink shared channel are transmitted in the same time slot, and there is no gap between the at least two repetitions. In one embodiment, the seventh priority of the second set grant physical uplink shared channel is the same as the eighth priority of the sixth physical uplink control channel used to transmit a sixth hybrid automatic repeat request confirmation of the fourth physical downlink shared channel.

In one embodiment, the thirty-fourth operation is a fifth uplink transmission including a third set grant physical uplink shared channel, and the third set grant physical uplink shared channel is configured with type B repetition. In one embodiment, the thirty-fifth operation is a fifth downlink reception including a fifth physical downlink shared channel (e.g., a semi-statically scheduled physical downlink shared channel) and is not triggered by a downlink control message. In one embodiment, the ninth priority of the third set grant physical uplink shared channel is the same as the tenth priority of the seventh physical uplink control channel used to transmit a seventh hybrid automatic repeat request acknowledgment of the fifth physical downlink shared channel.

[0088] In one embodiment, two operations in different directions of a plurality of operations (e.g., downlink reception and uplink transmission) are not set (or scheduled) by the network to be in the same time slot, symbol, or time interval. In other words, (e.g., if the two operations in different directions are triggered / scheduled by downlink control information and signals other than downlink control information, respectively), the communication device does not expect the two operations in different directions to be in the same time slot, symbol, or time interval.

[0089] In one embodiment, in different embodiments, two operations in the first operation to the thirty-fifth operation may be the same operation. For example, the first operation may be the same as the sixth operation, but is not limited thereto. In one embodiment, one operation in the first operation to the thirty-fifth operation may be the same as the uplink transmission of at least one uplink transmission in the aforementioned embodiment. For example, in the case where the first operation is the same as the uplink transmission of at least one uplink transmission, the communication device (for example, with the network end) performs one operation of multiple operations in a portion of the time slot through a portion of the resources within at least one uplink sub-band in response to the operation being an uplink transmission, the first indicator indicating that "uplink" is used for a portion of the time slot and the resources overlap with at least one downlink sub-band in a special symbol of a special symbol set, but is not limited thereto. In one embodiment, the uplink transmission of at least one uplink transmission in the aforementioned different embodiments may be the same uplink transmission. For example, an uplink transmission of at least one uplink transmission is configured with first spatial relationship information and second spatial relationship information, and through a portion of resources within at least one uplink sub-band, in a special symbol of a special symbol set, the communication device performs an uplink transmission of at least one uplink transmission in response to the resources overlapping with at least one downlink sub-band in the special symbol, but is not limited to this.

The process 40 is used for a communication device (eg Figure 1 The communication device 14 or Figure 2 The communication device 20) is used to determine the priorities of multiple operations (such as the multiple operations of the process 30). The process 40 can be compiled into a program code 214 and includes the following steps:

[0091] Step 400: Start.

[0092] Step 402: De-prioritize the priority of at least one first operation of the plurality of operations in response to the at least one first operation corresponding to a low priority indicator.

[0093] Step 404: When the number of the at least one first operation is greater than 1, is the at least one first operation of the plurality of operations triggered (or scheduled) by the same trigger signal type? If yes, execute step 406. If no, execute step 408.

[0094] Step 406: Lower the priority of at least one second operation of the at least one first operation in response to the at least one second operation including a reference signal, in response to the at least one second operation being the first or last operation in the at least one first operation, or in response to the at least one second operation being triggered (or scheduled) by a downlink control information, wherein the downlink control information ends earlier than other downlink control information of other operations that trigger the at least one first operation, and execute step 410.

[0095] Step 408: Reduce the priority of at least one third operation of the at least one first operation in response to the at least one third operation not being triggered (or scheduled) by a downlink control message.

[0096] Step 410: End.

[0097] The following embodiments may be used for process 40. In one embodiment, the low priority indicator may be a priority indicator having a second value (e.g., a priority indicator "0") of the embodiment of process 30, but is not limited thereto. In one embodiment, the trigger signal type may be a downlink control information signal and a non-downlink control information signal. The non-downlink control information signal may be a signal other than the downlink control information, such as a higher layer signal (e.g., a radio resource control signal), but is not limited thereto. In one embodiment, when the number of at least one first operation is 1, the communication device determines that at least one first operation has the lowest priority among multiple operations. In one embodiment, when multiple priority indicators corresponding to multiple operations have the same value, step 402 may be ignored.

The process 50 is used for a communication device (eg Figure 1 The communication device 14 or Figure 2 The communication device 20) is used to determine the priorities of multiple operations (such as the multiple operations of the process 30). The process 50 can be compiled into a program code 214 and includes the following steps:

[0099] Step 500: Start.

[0100] Step 502: Reduce the priority of at least one first operation of the plurality of operations in response to the at least one first operation being triggered (or scheduled) by at least one non-DLCI signal.

[0101] Step 504: When the number of the at least one first operation is greater than 1, does the at least one priority indicator corresponding to the at least one first operation have the same value? If yes, execute step 506. If no, execute step 508.

[0102] Step 506 : Lowering the priority of at least one second operation of the at least one first operation in response to the at least one second operation including a reference signal or in response to the at least one second operation being triggered later than other operations of the at least one first operation, and executing step 510 .

[0103] Step 508: Lowering the priority of at least one third operation of the at least one first operation in response to the at least one third operation corresponding to a low priority indicator.

[0104] Step 510: End.

[0105] The following embodiments may be used for process 50. In one embodiment, the low priority indicator may be a priority indicator having a second value (e.g., a priority indicator "0") of the embodiment of process 30, but is not limited thereto. In one embodiment, when the number of at least one first operation is 1, the communication device determines that at least one first operation has the lowest priority among multiple operations. In one embodiment, when multiple operations are triggered (or scheduled) by the same trigger signal type, step 502 may be ignored. In one embodiment, the trigger signal type may be a downlink control information signal and a non-downlink control information signal. The non-downlink control information signal may be a signal other than the downlink control information, such as a higher layer signal (e.g., a radio resource control signal), but is not limited thereto.

[0106] Figure 6 FIG. 6 is a schematic diagram of a time slot 60 according to an embodiment of the present invention. Figure 6 In the embodiment, time slot 60 includes downlink sub-bands 600 and 610 and uplink sub-band 620. Three operations (i.e., downlink reception DL0, uplink transmission UL0, and uplink transmission UL1) are set to be performed in time slot 60 and do not overlap each other in time. That is, there are two switching points in time slot 60. One switching point is between uplink transmission UL0 and downlink reception DL0, and the other switching point is between downlink reception DL0 and uplink transmission UL1.

[0107] exist Figure 6In Table 62, information of three operations of cases 1 to 8 is shown. The information in Table 62 includes trigger signals of three operations (e.g., trigger signal types) and data of three operations. In Table 62, "DCI" represents that the operation is triggered by downlink control information. "Non-DCI" represents that the operation is triggered by non-downlink control information signals (e.g., radio resource control signals). "HARQ" represents that the operation includes hybrid automatic repeat request confirmation. "SR" represents that the operation includes scheduling request. "SRS" represents that the operation includes sounding reference signal. "SPS-PDSCH" represents that the operation includes semi-static scheduling physical downlink shared channel. "PDSCH" represents that the operation includes scheduling physical downlink shared channel. "P-CSI-RS" represents that the operation includes periodic channel state information reference signal. "A-CSI-RS" represents that the operation includes aperiodic channel state information reference signal.

[0108] exist Figure 6 In the table 62, it is assumed that the priority indicators corresponding to the three operations have the same value, and the triggering order of the three operations is uplink transmission UL0, downlink reception DL0 and uplink transmission UL1. In situations 1 to 8, the communication device (for example, according to process 40 or 50) determines that one of the three operations has the lowest priority, and discards the operation with the lowest priority to reduce the number of switching points in time slot 60. The oblique line blocks in table 62 are the operations with the lowest priority determined and discarded by the communication device. Then, in time slot 60, the communication device executes the remaining operations (for example, at least one operation of process 30).

[0109] In case 1, the communication device determines that uplink transmission UL1 has the lowest priority in response to uplink transmission UL1 being triggered later than uplink transmission UL0 and downlink reception DL0. In case 2, the communication device determines that downlink reception DL0 has the lowest priority in response to downlink reception DL0 being triggered by a non-downlink control information signal and including a reference signal. In case 3, the communication device determines that uplink transmission UL1 has the lowest priority in response to uplink transmission UL1 being triggered by a non-downlink control information signal and being triggered later than uplink transmission UL0.

[0110] In case 5, the communication device determines that uplink transmission UL1 has the lowest priority in response to uplink transmission UL1 being triggered by a non-downlink control information signal and being triggered later than downlink reception DL0. In case 6, the communication device determines that downlink reception DL0 has the lowest priority in response to downlink reception DL0 being triggered by a non-downlink control information signal. In case 7, the communication device determines that uplink transmission UL1 has the lowest priority in response to uplink transmission UL1 being triggered by a non-downlink control information signal. In case 8, the communication device determines that uplink transmission UL1 has the lowest priority in response to uplink transmission UL1 being triggered later than uplink transmission UL0 and downlink reception DL0.

[0111] Figure 7 FIG. 7 is a schematic diagram of a time slot 70 according to an embodiment of the present invention. Figure 7 In the embodiment, time slot 70 includes downlink sub-bands 700 and 710 and uplink sub-band 720. Three operations (i.e., downlink reception DL0, downlink reception DL1 and uplink transmission UL0) are set to be performed in time slot 70 and do not overlap each other in time. That is, there are two switching points in time slot 70. One switching point is between downlink reception DL0 and uplink transmission UL0, and the other switching point is between uplink transmission UL0 and downlink reception DL1.

The priority indicator "1" has a higher priority than the priority indicator "0". In cases 1 to 6, the communication device (for example, according to process 40 or 50) determines that one of the three operations has the lowest priority, and discards the operation with the lowest priority to reduce the number of switching points in the time slot 70. The slashed blocks in the table 72 are the operations with the lowest priority determined and discarded by the communication device. Then, in the time slot 70, the communication device executes the remaining operations (for example, at least one operation of the process 30).

The downlink control information is used to trigger the three operations respectively. In case 1, the communication device determines that uplink transmission UL0 has the lowest priority in response to the fact that uplink transmission UL0 has a priority indicator "0" and the downlink control information that triggers uplink transmission UL0 ends earlier than the downlink control information that triggers downlink reception DL0. In case 2, the communication device determines that downlink reception DL1 has the lowest priority in response to the fact that downlink reception DL1 has a priority indicator "0" and the downlink control information that triggers downlink reception DL1 ends earlier than the downlink control information that triggers downlink reception DL0. In case 3, the communication device determines that downlink reception DL1 has the lowest priority in response to the fact that downlink reception DL1 has a priority indicator "0" and the downlink control information that triggers downlink reception DL1 ends earlier than the downlink control information that triggers uplink transmission UL0.

[0114] exist Figure 7In one embodiment, it is assumed that two of the three operations have priority indicators “0” and are triggered by different trigger signal types (e.g., downlink control information and non-downlink control information signals). In case 1, the communication device determines that uplink transmission UL0 has the lowest priority in response to the uplink transmission UL0 having the priority indicator “0” and being triggered by a non-downlink control information signal. In case 2, downlink reception DL0 is triggered by downlink control information, and downlink reception DL1 is triggered by a non-downlink control information signal. The communication device determines that downlink reception DL1 has the lowest priority in response to the downlink reception DL1 having the priority indicator “0” and being triggered by a non-downlink control information signal. In case 3, the uplink transmission UL0 is triggered by downlink control information, and the downlink reception DL1 is triggered by a non-downlink control information signal. The communication device determines that downlink reception DL1 has the lowest priority in response to the downlink reception DL1 having the priority indicator “0” and being triggered by a non-downlink control information signal. In case 4, the communication device determines that downlink reception DL0 has the lowest priority in response to downlink reception DL0 having a priority indicator of "0".

The communication device receives an uplink / downlink configuration and a special resource configuration (not shown) from the network end. Figure 8 ). The uplink-downlink configuration and the special resource configuration may be the first configuration and the second configuration of process 30, respectively, which are used to indicate the type (e.g., direction) of time slots 0-9 in a frame (e.g., frame 82 or frame 84). The uplink-downlink configuration indicates that time slots 0-3 are downlink time slots, time slots 4-5 are flexible time slots, and time slots 6-9 are uplink time slots. The special resource configuration indicates that time slots 2-5 are special time slots. The uplink time slot, the downlink time slot, the flexible time slot, and the special time slot are represented as "U", "D", "F", and "S", respectively.

[0116] exist Figure 8, according to the uplink-downlink configuration, the communication device determines the type of time slots 0 to 9 in the frame. The determined frame can be represented as frame 82. Then, according to the special resource configuration, the communication device re-determines time slots 2 to 5 as special time slots. The re-determined frame can be represented as frame 84. Each of time slots 0 to 1 of frame 84 includes a resource DL_R, and the resource DL_R includes a downlink sub-band 800. Each of time slots 2 to 5 of frame 84 includes a resource S_R, and the resource S_R includes downlink sub-bands 810, 820 and an uplink sub-band 830. Each of time slots 6 to 9 of frame 84 includes a resource UL_R, and the resource UL_R includes an uplink sub-band 840. In the resources DL_R, S_R and UL_R, the downlink sub-band is represented by a slash block, and the uplink sub-band is represented by a blank block.

[0117] exist Figure 8 In one embodiment of the present invention, the communication device further receives an indicator (not shown) from the network. Figure 8 ). The indicator may be the first indicator of the embodiment of process 30, and indicates that the direction of time slot 2 of frame 84 is downlink and the direction of time slots 3-5 of frame 84 is uplink. Since time slots 0-1 of frame 84 are downlink time slots, in time slots 0-1 of frame 84, in downlink sub-band 800, the communication device may perform downlink reception. In time slot 2 of frame 84, in downlink sub-bands 810 and / or 820, the communication device may perform downlink reception in response to the indicator indicating that the direction of time slot 2 is downlink. In time slots 3-5 of frame 84, in uplink sub-band 830, the communication device may perform uplink transmission in response to the indicator indicating that the direction of time slots 3-5 is uplink. Since time slots 6-9 of frame 84 are uplink time slots, in time slots 6-9 of frame 84, in uplink sub-band 840, the communication device may perform uplink transmission.

[0118] exist Figure 8 In one embodiment, the communication device does not receive an indicator (not shown) from the network. Figure 8). The indicator may be the second indicator or the third indicator of the embodiment of process 30, and indicates the direction of time slots 2 to 5 of frame 84. Since time slots 0 to 1 of frame 84 are downlink time slots, in time slots 0 to 1 of frame 84, in downlink sub-band 800, the communication device may perform downlink reception. In time slots 2 to 3 of frame 84, in downlink sub-bands 810 and / or 820, the communication device may perform downlink reception in response to time slots 2 to 3 being determined as downlink time slots (i.e., time slots 2 to 3 of frame 82) according to the uplink-downlink configuration. In time slots 4 to 5 of frame 84, in uplink sub-band 830, the communication device may perform uplink transmission in response to time slots 4 to 5 being determined as flexible time slots (i.e., time slots 4 to 5 of frame 82) according to the uplink-downlink configuration. Since time slots 6 to 9 of the frame 84 are uplink time slots, in time slots 6 to 9 of the frame 84 , in the uplink sub-band 840 , the communication device may perform uplink transmission.
