[0052] 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 Communication device 14 or Figure 2 A communication device 20) is provided to handle communication with the serving cell.

[0053] The process 30 can be compiled into the program code 214 and includes the following steps:

[0054] Step 300: Start.

[0055] 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.

[0056] 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.

[0057] Step 306: Receive an indicator for a first uplink transmission in a bandwidth part (BWP) of the serving cell from the network, wherein the first uplink transmission corresponds to a first priority index.

[0058] Step 308: Perform the first uplink transmission according to a first resource configuration in response to an overlap of the first uplink transmission with an uplink symbol of the uplink symbol set.

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). Then, 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 an indicator for a first uplink transmission in a bandwidth portion of the serving cell from the network. The first uplink transmission corresponds to a first priority indicator. According to the first resource configuration, the communication device (e.g., with the network) performs a first uplink transmission in response to the first uplink transmission overlapping (e.g., completely) with an uplink symbol (or at least one uplink symbol) of the uplink symbol set. The communication device determines whether to perform a first uplink transmission (e.g., with a network) in response to the first uplink transmission overlapping (e.g., completely) with a special symbol (or at least one special symbol) of the special symbol set in time. That is, the special symbol includes an uplink resource (e.g., at least one uplink sub-band), and the first uplink transmission can be performed in the uplink resource of the special symbol.

In one embodiment, a communication device (e.g., with a network end) performs the first uplink transmission in a non-special symbol (e.g., an uplink symbol of an uplink symbol set) or a special symbol. Furthermore, the first uplink transmission is performed in a non-special symbol in response to an indicator being indicated by a signal other than a downlink control information (e.g., a radio resource control signal). The first uplink transmission is performed in a special symbol in response to an indicator being indicated by a downlink control information.

[0067] In one embodiment, based on the location of the transmission resource for the first uplink transmission and at least one location of the at least one downlink sub-band, the communication device determines whether to perform the first uplink transmission (e.g., with the network) in response to the first uplink transmission overlapping with a special symbol of the special symbol set in time.

That is, (e.g., if the first uplink transmission includes the fourth uplink control information set), the communication device can determine the uplink resources for the first uplink transmission according to the first configuration.

[0079] In one embodiment, in a special symbol of the special symbol set (same as or different from the special symbol of process 30), the communication device (e.g., with the network end) performs a first downlink reception in response to the first downlink reception not overlapping with at least one uplink sub-band.

[0080] In one embodiment, the communication device is set with time information. In one embodiment, the time information indicates whether at least one resource can be used for the first uplink transmission. In one embodiment, a resource of the at least one resource includes (for example) a radio frame, a time slot, a special symbol or a time slot including at least one special symbol. In one embodiment, the time information includes (for example) a bitmap. In one embodiment, at least one bit in the bitmap corresponds to at least one resource. In one embodiment, a bit with a third value in the bitmap indicates that the first uplink transmission can be performed in the corresponding resource. In one embodiment, a bit with a fourth value in the bitmap indicates that the first uplink transmission cannot be performed in the corresponding resource.

[0081] In one embodiment, based on the identification of the communication device, the indicator of the time slot containing the special symbol, and at least one of the at least one parameter, the communication device determines whether to perform a first uplink transmission (e.g., with a network end) in response to the first uplink transmission overlapping with a special symbol of the special symbol set in time. In one embodiment, a parameter of the at least one parameter is set by at least one of a communication device characteristic (specific), a bandwidth portion characteristic, and a higher layer signal (e.g., a radio resource control signal). In one embodiment, in the special symbol, the communication device (e.g., with a network end) performs a first uplink transmission in response to the equation (Equation 1) being satisfied. The equation (Equation 1) can be expressed as follows:

[0082] mod(ID CD +N,P)=K (Formula 1)

[0083] Where ID CD is the identification of the communication device, N is an index of the time slot containing the special symbol, and P and K are parameters set by at least one of the characteristics of the communication device, the characteristics of the bandwidth portion, and a higher layer signal (e.g., a radio resource control signal). In one embodiment, in the special symbol, the communication device prohibits (e.g., with the network end) from performing the first uplink transmission in response to the fact that the procedure (Formula 1) is not satisfied. In other words, whether to send the uplink transmission in the special symbol is determined based on the time domain information.

[0084] In one embodiment, the communication device does not expect to perform a first uplink transmission with a first priority indicator of a second value in a special symbol in response to the indicator being indicated by the downlink control information.

In one embodiment, a hybrid automatic repeat request confirmation included in the first priority indicator is discarded (dropped) in response to the first uplink transmission overlapping with the special symbol or at least one downlink sub-band. In one embodiment, when the network end triggers a hybrid automatic repeat request confirmation feedback (e.g., type 3 hybrid automatic repeat request confirmation feedback) or sets a hybrid automatic repeat request confirmation deferring, the communication device transmits the discarded hybrid automatic repeat request confirmation in a first time slot after the special symbol. In one embodiment, the first time slot is selected by the network end through the downlink control information. In one embodiment, the time slot (e.g., the first time slot) includes multiple symbols (e.g., multiple consecutive symbols).

[0085] In one embodiment, the first downlink reception has a lower priority or the same priority as the first uplink transmission having a first priority indicator, wherein the first priority indicator is a second value. In one embodiment, the first downlink reception includes a reference signal (e.g., a channel state information reference signal or a positioning reference signal (PRS)). In one embodiment, the first downlink reception corresponds to a first search space (SS) set. The first search space set includes at least one of a common search space (CSS) set (e.g., a Type 3 physical downlink control channel common search space set (Type3-PDCCH CSS set)) and a user end specific search space (UEspecific SS, USS) set. In one embodiment, the first downlink reception includes a physical downlink shared channel scheduled by downlink control information from the first search space set.

[0086] In one embodiment, a first downlink reception including a physical downlink shared channel has a higher priority than a second downlink reception in response to a first uplink transmission having a first priority indicator of a first value including a hybrid automatic repeat request acknowledgment corresponding to the physical downlink shared channel. In one embodiment, a first downlink reception including a physical downlink shared channel has a lower priority than a second downlink reception in response to a first uplink transmission having a first priority indicator of a second value including a hybrid automatic repeat request acknowledgment corresponding to the physical downlink shared channel.

[0087] 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 first resource configuration and a starting physical resource block. In one embodiment, on the uplink resource, in a special symbol, the communication device (e.g., with a network end) performs a first uplink transmission (or a second / third uplink transmission). The first uplink transmission corresponds to a first priority indicator, and the first priority indicator is a first value or a second value. In one embodiment, the first number of physical resource blocks of the uplink resource is the same as the second number of physical resource blocks used for the first uplink transmission, and the first uplink transmission overlaps with the uplink symbols of the uplink symbol set. In one embodiment, the starting physical resource block is determined based on at least one of an offset, an indicator, a first resource configuration, a downlink control information, and a higher layer signal (e.g., a radio resource control signal). 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 a dedicated offset for the first uplink transmission set by a higher layer signal. In one embodiment, the resource configuration is set for the first uplink transmission. In one embodiment, the starting physical resource block is indicated for the first uplink transmission.

In one embodiment, the starting physical resource block is dedicated to at least one special symbol. In one embodiment, the first uplink transmission is a physical uplink control channel or a physical uplink shared channel.

[0088] In one embodiment, a communication device (e.g., with a network end) performs a first uplink transmission in a special symbol by using a portion of resources used for a first uplink transmission in at least one uplink sub-band in response to the resources overlapping with at least one downlink sub-band in the special symbol. The first uplink transmission corresponds to a first priority indicator, and the first priority indicator is a first value or a second value. That is, the first uplink transmission is not performed by using the remaining portion of resources used for the first uplink transmission in at least one downlink sub-band. In one embodiment, if the first physical resource block of the resources used for the first uplink transmission overlaps with at least one downlink sub-band, the communication device determines that the first physical resource block used to perform the first 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 used for the first uplink transmission overlaps with at least one downlink sub-band, the communication device determines that the last physical resource block used to perform the first uplink transmission is the last physical resource block of the at least one uplink sub-band.

[0089] In one embodiment, the communication device determines the uplink resource for the first uplink transmission in the special symbol according to the second resource configuration. In one embodiment, the communication device determines the uplink resource for the first uplink transmission in the special symbol according to the second resource configuration and the third resource configuration. In one embodiment, after determining the uplink resource for the first uplink transmission in the special symbol according to the second resource configuration, the communication device (for example, with the network end) performs the first uplink transmission through the uplink resource. In one embodiment, the second resource configuration is associated with a fourth priority indicator, and the fourth priority indicator is a first value. In one embodiment, the third resource configuration is associated with a fifth priority indicator, and the fifth priority indicator is a second value. In one embodiment, the second resource configuration includes a first list of multiple first uplink resources for the special symbol. In one embodiment, the multiple first uplink resources include (for example) multiple first physical uplink control channel resources. In one embodiment, the third resource configuration includes a second list of multiple second uplink resources for the special symbol. In one embodiment, the plurality of second uplink resources include (for example, are) a plurality of second physical uplink control channel resources. In one embodiment, each of the plurality of first uplink resources and the plurality of second uplink resources is configured with at least one of a resource identifier and a payload size.

[0090] In one embodiment, according to the first load size of the first uplink transmission, the communication device determines the uplink resource used for the first uplink transmission in a special symbol. In one embodiment, after determining the uplink resource used for the first uplink transmission in a special symbol according to the first load size of the first uplink transmission, the communication device (for example, with the network end) performs the first uplink transmission through the uplink resource. In one embodiment, the uplink resource is selected from a plurality of third uplink resources. In one embodiment, at least one uplink resource of the plurality of third uplink resources is associated with the second load size. In one embodiment, the first uplink transmission includes more than one uplink control information type. In one embodiment, according to the first load size of the first uplink transmission and a plurality of maximum load sizes of the plurality of third uplink resources, the communication device determines the uplink resource used for the first uplink transmission in a special symbol. In one embodiment, a plurality of maximum load sizes are used for a third list indication of a plurality of third uplink resources.

[0091] In one embodiment, the communication device performs (and / or determines whether to perform) the first uplink transmission according to the factors in the aforementioned embodiments. For example, according to the first priority indicator of the first physical uplink control channel in the first uplink transmission and the trigger type of the indicator, the communication device determines whether to perform the first uplink transmission (for example, with the network end), but is not limited thereto.

[0092] In one embodiment, the communication device receives an indicator (different from the indicator of process 30) for a fourth uplink transmission in the bandwidth portion of the serving cell from the network. In one embodiment, according to the first resource configuration, the communication device (e.g., with the network) performs a fourth uplink transmission in response to the fourth uplink transmission overlapping (e.g., completely) with an uplink symbol (or at least one uplink symbol) of an uplink symbol set. In one embodiment, the communication device determines (e.g., with the network) whether to perform the fourth uplink transmission in response to the fourth uplink transmission overlapping (e.g., completely) with a special symbol (or at least one special symbol) of a special symbol set in time. The embodiments related to the fourth uplink transmission can refer to the aforementioned embodiments related to the first uplink transmission, which are not repeated here.

[0093] In one embodiment, the communication device performs (and / or determines whether to perform) multiple uplink transmissions according to different factors in the aforementioned multiple embodiments. For example, the communication device determines whether to perform the first uplink transmission (e.g., with the network end) according to the first priority indicator of the first physical uplink control channel in the first uplink transmission, and determines whether to perform the fourth uplink transmission (e.g., with the network end) according to at least one of the identification of the communication device, the indicator of the time slot containing the special symbol, and the at least one parameter, but is not limited thereto.

[0094] In one embodiment, the first value has a higher priority than the second value. In one embodiment, the first value is "1", but not limited thereto. In one embodiment, the second value is "0", but not limited thereto.

[0095] Figure 4 FIG. 4 is a schematic diagram of a communication 40 between a communication device and a network end according to an embodiment of the present invention. The communication device receives an uplink downlink configuration (UL-DL configuration) and a special resource configuration (not shown) from the network end. Figure 4 ). 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 42 or frame 44). 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, downlink time slot, flexible time slot, and special time slot are represented as "U", "D", "F", and "S", respectively. According to the uplink-downlink configuration, the communication device determines the type of time slots 0-9 in the frame. The determined frame may be represented as frame 42. Then, according to the special resource configuration, the communication device re-determines time slots 2-5 as special time slots. The re-determined frame may be represented as frame 44.

[0096] Since time slots 0 to 1 of the frame 44 are downlink time slots, in the time slots 0 to 1 of the frame 44, the communication device does not perform a high priority (HP) uplink transmission HP_UL (e.g., a first uplink transmission including a first physical uplink control channel with a first priority indicator, wherein the first priority indicator is a first value) and a low priority (LP) downlink transmission LP_UL (e.g., a first uplink transmission including a first physical uplink control channel with a first priority indicator, wherein the first priority indicator is a second value) with the network. In the time slots 2 to 5 of the frame 44, the communication device may perform a high priority uplink transmission HP_UL with the network, and prohibits performing a low priority uplink transmission LP_UL with the network in response to the low priority uplink transmission LP_UL having a low priority. Since time slots 6-9 of frame 44 are uplink time slots, the communication device can perform high priority uplink transmission HP_UL and / or low priority uplink transmission LP_UL with the network in time slots 6-9 of frame 44. That is, uplink transmission can be performed in time slots 2-9 of frame 44.

[0097] It should be noted that even if the communication device is configured to multiplex uplink control information corresponding to the high priority uplink transmission HP_UL and the low priority uplink transmission LP_UL, the high priority uplink transmission HP_UL and the low priority uplink transmission LP_UL are not multiplexed in the time slots 2 to 5 of the frame 44. Figure 4 For the sake of simplicity, the high priority uplink transmission HP_UL and the low priority uplink transmission LP_UL in time slots 1, 3, 5, 7, and 9 of the frame 44 are not shown.

[0098] Figure 5 FIG. 5 is a schematic diagram of a communication 50 between a communication device and a network end according to an embodiment of the present invention. Each of the frames 52 and 54 includes time slots 0 to 9. The frames 52 and 54 can be referred to as Figure 4The frames 42 and 44 are not described in detail here. In the time slot 1 of the frame 54, the communication device performs a downlink reception DL0 including a physical downlink shared channel with the network, and in the time slot 4 of the frame 54, it is expected to perform a low priority downlink transmission LP_UL including a low priority uplink control information corresponding to the physical downlink shared channel with the network. In the time slot 4 of the frame 54, the communication device prohibits performing a low priority downlink transmission LP_UL with the network (for example, in response to the low priority downlink transmission LP_UL being discarded), and in the time slot 5 of the frame 54, the transmission of the low priority downlink transmission LP_UL is deferred. In time slot 5 of frame 54, the communication device prohibits performing low priority downlink transmission LP_UL with the network in response to the low priority downlink transmission LP_UL overlapping with the high priority uplink transmission HP_UL0 in time slot 5 of frame 54, and multiplexing the low priority uplink control information in the low priority downlink transmission LP_UL and at least one high priority uplink control information in the high priority uplink transmission HP_UL0 into the high priority uplink transmission HP_UL1. In time slot 5 of frame 54, the communication device and the network perform the high priority uplink transmission HP_UL1 with the multiplexed uplink control information.

[0099] Figure 6 FIG. 6 is a schematic diagram of a communication 60 between a communication device and a network end according to an embodiment of the present invention. Each of the frames 62 and 64 includes time slots 0 to 9. The frames 62 and 64 can be referred to as Figure 4 Frames 42 and 44 are not described in detail here. Since time slots 0 to 1 of frame 64 are downlink time slots, in time slots 0 to 1 of frame 64, the communication device does not perform high priority uplink transmission HP_UL and low priority uplink transmission LP_UL with the network. In time slots 2 to 3 of frame 64, the communication device can perform high priority uplink transmission HP_UL with the network, and prohibits performing low priority uplink transmission LP_UL with the network, in response to time slots 2 to 3 of frame 64 being set as downlink time slots according to the uplink-downlink configuration. In time slots 4 to 5 of frame 64, the communication device can perform high priority uplink transmission HP_UL and / or low priority uplink transmission LP_UL with the network, in response to time slots 2 to 3 of frame 64 being set as flexible time slots according to the uplink-downlink configuration, and the flexible time slots are indicated as uplink time slots by the downlink control information. Since time slots 6-9 of frame 64 are uplink time slots, the communication device can perform high priority uplink transmission HP_UL and / or low priority uplink transmission LP_UL with the network in time slots 6-9 of frame 64. That is, uplink transmission can be performed in time slots 4-9 of frame 64.

[0100] exist Figure 6For simplicity, the high priority uplink transmission HP_UL and the low priority uplink transmission LP_UL in time slots 1, 3, 5, 7, and 9 of the frame 64 are not shown.

[0101] Figure 7 FIG. 7 is a schematic diagram of a communication 70 between a communication device and a network end according to an embodiment of the present invention. Each of the frames 72 and 74 includes time slots 0 to 9. The frames 72 and 74 can be referred to as Figure 4 Frames 42 and 44 are not described in detail here. The uplink transmission UL0 is a periodic transmission and is scheduled / set by a higher layer signal (such as a radio resource control signal). The communication device expects to send the uplink transmission UL0 in time slots 0, 2, 4, 6 and 8 of frame 74. Since the uplink transmission UL0 cannot be performed in the downlink time slot, in time slot 0 of frame 74, the communication device does not perform the uplink transmission UL0 with the network. In time slots 2 and 4 of frame 74, the communication device is prohibited from performing the uplink transmission UL0 with the network in response to the uplink transmission UL0 not being scheduled / set by the downlink control information. Since time slots 6 to 9 of frame 74 are uplink time slots, in time slots 6 and 8 of frame 74, the communication device and the network perform the uplink transmission UL0. It should be noted that the communication device can multiplex the uplink control information and high priority uplink transmission (not shown) of the uplink transmission UL0 in time slots 2 and / or 4 of frame 72. Figure 7 In response to the uplink transmission UL0 in time slots 2 and / or 4 of frame 72 being scheduled / configured by the downlink control information.

[0102] Figure 8 FIG. 8 is a schematic diagram of a communication 80 between a communication device and a network end according to an embodiment of the present invention. Each of the frames 82 and 84 includes time slots 0 to 9. The frames 82 and 84 can be referred to as Figure 4 Frames 42 and 44 are not described here. In time slot 0 of frame 84, the communication device receives downlink control information DCI0 from the network. Then, according to the downlink control information DCI0, in time slot 1 of frame 84, the communication device and the network perform downlink reception DL0 including a physical downlink shared channel, and according to the downlink control information DCI0, in time slot 4 of frame 84, it is expected that the network will perform uplink transmission UL0 including uplink control information corresponding to the physical downlink shared channel. In time slot 4 of frame 84, the communication device performs uplink transmission UL0 in response to the uplink transmission UL0 being scheduled by the downlink control information DCI0.

[0103] Fig. 9Schematic diagram of special symbols 90 and 92 according to a second embodiment of the present invention. Each of the special symbols 90 and 92 includes downlink sub-bands 900 and 910 and uplink sub-band 920. Uplink transmission UL0 is scheduled to be performed in special symbol 90 and does not overlap with downlink sub-bands 900 and 910. Therefore, in special symbol 90, the communication device can perform uplink transmission UL0 with the network. Uplink transmission UL1 is scheduled to be performed in special symbol 92 and overlaps with downlink sub-band 900. Therefore, in special symbol 92, the communication device is prohibited from performing uplink transmission UL1 with the network. In one embodiment, "special symbols 90 and 92" can be replaced by "special time slots 90 and 92".

[0104] Fig.10 FIG. 1 is a schematic diagram of a communication 100 between a communication device and a network terminal according to an embodiment of the present invention. Fig.10 There are uplink symbols 102 and special symbols 104. Special symbols 104 include downlink sub-bands 1000 and 1010 and uplink sub-band 1020. The communication device receives an offset (not shown) in a downlink control message or a high-layer signal from the network. Fig.10 The offset indicates the number of physical resource blocks by which the uplink transmission UL0 is shifted. In the uplink symbol 102, the communication device may perform the uplink transmission UL0 with the network, and / or in the special symbol 104, the communication device may perform the uplink transmission UL0 with the network by shifting the uplink transmission UL0 according to the offset, so as to avoid the uplink transmission UL0 from overlapping with the downlink sub-band 1010 of the special symbol 104.
