[0176] (3) The first indication information is indicated by the NDI field and the MCS field, the NDI field indicates the initial transmission and the MCS field is 11111, 11110, 11101, or 11100;

[0177] (4) The first indication information is indicated by the NDI field and the RV field, the NDI field indicates 0 and the RV field indicates non-all 0;

[0178] (5) The first indication information is indicated by the RV field and the HARQ number field, and the RV field and / or the HARQ number field are not all zeros;

[0179] (6) The first indication information is indicated by the RV field, the HARQ number field, the MCS field, and the FDRA field, and satisfies one or more of the following conditions: the HARQ number field is not all 0s, the RV field is not all 0s, the MCS field is not all 1s, and the FDRA field is not all 1s;

[0180] (7) The first indication information is indicated by the RV field, the MCS field, and the FDRA field, and satisfies one or more of the following conditions: the RV field is not all 0, the MCS field is not all 1, and the FDRA field is not all 1.

[0181] The aforementioned (4)-(7) are particularly applicable to CS-RNTI scrambled DCI.

[0182] For example, for the aforementioned method 2, the first indication information is indicated in one or more of the following ways:

[0183] (1) The first indication information is indicated by an RV field, the RV field is not all zeros, and different states of the RV field are used to indicate information about the first SBFD symbol set. For example, for a CS-RNTI scrambled DCI, the RV field contains two bits, and bit states 01, 10, and 11 respectively indicate that the first DCI is used to cancel or disable SBFD symbols, and the three different states indicate different SBFD symbol sets;

[0184] (2) The first indication information is indicated by the NDI field and the MSC field, the NDI field indicates initial transmission and the MCS field is 11111, 11110, 11101, or 11100, and different states of the MCS field are used to indicate information about the first SBFD symbol set;

[0185] (3) The first indication information is indicated by the RV field and the HARQ number field, the RV field and / or the HARQ number field is not all zero, and is combined with different states of the HARQ number field and different states of the RV field to indicate information of the first SBFD symbol set. For example, for CS-RNTI scrambled DCI, when the HARQ field contains 4 bits and the RV field contains 2 bits, the HARQ field indicates 1111 and the RV field indicates 00, the HARQ field indicates 1111 and the RV field indicates 01, the HARQ field indicates 1111 and the RV field indicates 10, and the HARQ field indicates 1111 and the RV field indicates 11. Each of these four states indicates an SBFD symbol set.

[0186] For example, in the above-mentioned method three, the second indication information indicates the symbol or time slot corresponding to the first SBFD symbol set in the form of a bitmap. For example, on the basis of the existing DCI format, the SBFD symbol set can be indicated in the form of a bitmap by setting one or more existing fields. Alternatively, the second indication information includes the starting position and length of the target symbol or target time slot, wherein the target symbol or the target time slot is a symbol or time slot included in the first SBFD symbol set. For example, the TDRA field can be used to indicate the starting position and length of the target symbol or target time slot.

[0187] Step 102: Determine a first SBFD symbol set based on the first DCI.

[0188] In this embodiment of the present disclosure, the terminal may determine the first SBFD symbol set in any of the following ways:

[0189] Method 1: Determine the first SBFD symbol set according to a protocol agreement.

[0190] The information agreed upon by the protocol includes: taking N consecutive symbols or time slots starting from the n+Mth symbol or time slot as the first SBFD symbol set, where n is the symbol or time slot of the received first DCI, M is an integer greater than or equal to 0, and N is a positive integer.

[0191] In this manner, the terminal or the network device may determine the first SBFD symbol set according to a protocol agreement. After receiving the first DCI, the terminal determines that the network device cancels or disables the first SBFD symbol set. The terminal determines the first SBFD symbol set according to a protocol agreement.

[0192] Method 2: Determine K SBFD symbol sets according to a protocol agreement, and determine one of the K SBFD symbol sets as the first SBFD symbol set according to the first indication information or the second indication information.

[0193] In this manner, the terminal may determine K SBFD symbol sets according to a protocol agreement, and then determine one of the K SBFD symbol sets as the first SBFD symbol set in combination with the first indication information or the second indication information.

[0194] Method three: Determine K SBFD symbol sets according to signaling sent by a network device (such as Radio Resource Control (RRC) signaling), and determine one of the K SBFD symbol sets as the first SBFD symbol set according to the first indication information or the second indication information.

[0195] In this manner, the terminal determines K SBFD symbol sets according to signaling, and then determines one of the K SBFD symbol sets as the first SBFD symbol set in combination with the first indication information or the second indication information.

[0196] In the embodiment of the present disclosure, the network device explicitly cancels or disables the SBFD symbol through the first DCI, thereby realizing a dynamic SBFD function, thereby reducing the complexity of the network device scheduling.

[0197] In the embodiment of the present disclosure, the terminal may further send feedback information via MAC CE, where the feedback information is used to indicate whether the first DCI is received. That is, the terminal may send feedback information via MAC CE regardless of whether the DCI is scrambled by the CS-RNTI or the C-RNTI.

[0198] In this embodiment of the present disclosure, the cancellation or disabling of the first SBFD symbol set may also have a certain validity period. The terminal can then determine the validity period for canceling or disabling the first SBFD symbol set, thereby facilitating the terminal's corresponding operations. The validity period may be a single SBFD configuration period or multiple consecutive SBFD configuration periods.

[0199] For example, the validity period is: the SBFD configuration period in which the first DCI is located, or the Lth SBFD configuration period after the SBFD configuration period in which the first DCI is located. Alternatively, the validity period is: multiple consecutive SBFD configuration periods starting from the SBFD configuration period in which the first DCI is located, or the Pth SBFD configuration period after the SBFD configuration period in which the first DCI is located; where L and P are integers greater than 0, and L and P can be predetermined or configured by the network device through RRC signaling. In this case, the multiple consecutive SBFD configuration periods can continue until the terminal receives the next first DCI.

[0200] In the embodiments of the present disclosure, it may be specified that the terminal does not wish to receive multiple first DCIs within an SBFD configuration period. In other words, the terminal does not support receiving multiple first DCIs within an SBFD configuration period, thereby avoiding frequent DCI reception. Accordingly, the network device will not send multiple first DCIs within an SBFD configuration period.

[0201] Alternatively, the protocol may also stipulate that at most one first DCI is sent within one SBFD configuration week.

[0202] Alternatively, there is no limit on the number of first DCIs sent within an SBFD cycle, but the protocol stipulates that the contents of the first DCIs sent within an SBFD cycle must be the same. Then, the terminal can determine that the contents of multiple first DCIs received within an SBFD configuration cycle are the same according to the protocol.

[0203] Alternatively, it is possible to support sending multiple first DCIs within one SBFD configuration cycle. For example, if a terminal receives a maximum of multiple first DCIs within one SBFD configuration cycle, the contents indicated by the multiple first DCIs may be the same or different. For example, if a terminal receives multiple first DCIs within one SBFD configuration cycle, the terminal determines whether the contents indicated by the first part of the multiple first DCIs are the same or different, and the contents indicated by the second part of the first DCIs are the same. The contents indicated by the second part of the first DCIs are the same as the contents indicated by the last first DCI in the first part of the DCIs.

[0204] Specifically, the protocol constrains that a maximum of T (T is an integer greater than 1) first DCIs be sent within an SBFD configuration week, and the indication content can be the same or different. Alternatively, within an SBFD cycle, there is no limit on the number of first DCIs, and the indication content for the first DCIs from 1 to T can be the same or different. For each first DCI from T+1 onwards within the SBFD cycle, the constraint is that the content indicated is the same as that indicated by the Tth first DCI. Then, the terminal can determine the indication content of the first DCIs from 1 to T according to the protocol provisions, and each first DCI from T+1 onwards can indicate the same content as that indicated by the Tth first DCI, where T is specified by the protocol or indicated by the network device.

[0205] After receiving the first DCI, the terminal may perform one or more of the following steps:

[0206] If the canceled or disabled first SBFD symbol set includes a first target symbol, the first target symbol is a symbol configured as a downlink symbol D or a flexible symbol F in the cell-level common configuration, and after determining that the first SBFD symbol set is canceled or disabled, the position corresponding to the first target symbol is the downlink symbol D. In this case, if the transmission direction scheduled or configured in all downlink symbols is uplink, the terminal may discard or delay uplink transmission;

[0207] If the canceled or disabled first SBFD symbol set includes a second target symbol, the second target symbol is a symbol configured as a flexible symbol F (for example, configured through TDD-UL-DL-ConfigCommon), and after determining that the first SBFD symbol set is canceled or disabled, the position corresponding to the second symbol is an uplink symbol U. At this time, if the transmission direction scheduled or configured in all uplink symbols is downlink, the downlink transmission is discarded or delayed;

[0208] If the canceled or disabled first SBFD symbol set includes a third target symbol, the third target symbol is a symbol configured (for example, through TDD-UL-DL-ConfigCommon) as a flexible symbol F, after determining that the first SBFD symbol set is canceled or disabled, the position corresponding to the third target symbol is the F symbol, and conflict processing is performed according to the processing method for the F symbol;

[0209] If the canceled or disabled first SBFD symbol set includes a fourth target symbol, the fourth target symbol is a symbol configured (for example, through TDD-UL-DL-ConfigCommon configuration) as a flexible symbol F, and after determining that the first SBFD symbol set is canceled or disabled, the transmission direction on the frequency domain resources corresponding to the uplink subband in the fourth target symbol is downlink; if the transmission direction scheduled or configured on the frequency domain resources corresponding to the uplink subband in the fourth target symbol is uplink, the terminal may discard or delay the uplink transmission.

[0210] 2 is a flowchart of an information processing method provided by an embodiment of the present disclosure, which is applied to a network device and includes the following steps:

[0211] Step 201: Send a first DCI to a terminal, where the first DCI is used to indicate cancellation or disabling of a first SBFD symbol set.

[0212] The specific implementation form of the first DCI may refer to the description of the aforementioned method embodiment.

[0213] In the embodiment of the present disclosure, the network device determines the first SBFD symbol by any of the following methods:

[0214] Determining the first SBFD symbol set according to a protocol agreement, wherein the protocol agreement information includes: using N consecutive symbols or time slots starting from the n+Mth symbol or time slot as the first SBFD symbol set, where n is a symbol or time slot for sending the first DCI, M is an integer greater than or equal to 0, and N is a positive integer;

[0215] Determine K SBFD symbol sets according to a protocol agreement, where the first SBFD symbol set is one of the K SBFD symbol sets indicated by the first indication information or the second indication information;

[0216] K SBFD symbol sets are configured for the terminal through signaling (such as RRC signaling), and the first SBFD symbol set is one of the K SBFD symbol sets indicated by the first indication information or the second indication information.

[0217] In the embodiment of the present disclosure, the specific indication methods of the first indication information and the second indication information can refer to the description of the above embodiments.

[0218] In the embodiment of the present disclosure, the network device can explicitly cancel or disable SBFD through the first DCI, that is, implement a dynamic SBFD function, thereby reducing the complexity of network device scheduling.

[0219] In some embodiments, the network device may further send third information to the terminal, where the third information is used to indicate SBFD symbol configuration information. The first SBFD symbol set includes all or part of the SBFD symbols within an SBFD symbol configuration period, and the SBFD symbol configuration period and all SBFD symbols within the SBFD symbol configuration period are indicated by the SBFD symbol configuration information.

[0220] In some embodiments, the network device may further determine a valid time for canceling or disabling the first SBFD symbol set; wherein the valid time is a single SBFD configuration period, or the valid time is a plurality of consecutive SBFD configuration periods.

[0221] For example, the valid time is: the SBFD configuration period in which the first DCI is located, or the Lth SBFD configuration period after the SBFD configuration period in which the first DCI is located. Alternatively, the valid time is: multiple consecutive SBFD configuration periods starting from the SBFD configuration period in which the first DCI is located or the Pth SBFD configuration period after the SBFD configuration period in which the first DCI is located; wherein L and P are integers greater than 0, and L and P can be predetermined or configured by the network device through RRC signaling. In this way, multiple consecutive SBFD configuration periods can continue until the next first DCI is sent.

[0222] In the embodiments of the present disclosure, it may be specified that the terminal does not wish to receive multiple first DCIs within an SBFD configuration period. In other words, the terminal does not support receiving multiple first DCIs within an SBFD configuration period, thereby avoiding frequent DCI reception. Accordingly, the network device will not send multiple first DCIs within an SBFD configuration period.

[0223] Alternatively, the protocol may also stipulate that at most one first DCI is sent within one SBFD configuration cycle. Then, the network device sends one first DCI within one SBFD configuration cycle.

[0224] Alternatively, there is no limit on the number of first DCIs sent within an SBFD cycle, but the protocol stipulates that the first DCIs sent within an SBFD cycle must indicate the same content. Therefore, the network device can send multiple first DCIs within an SBFD configuration cycle, and the first DCIs sent within an SBFD cycle must indicate the same content.

[0225] Alternatively, it is possible to support sending multiple first DCIs within one SBFD configuration cycle. For example, the protocol constrains that a maximum of T DCIs are sent within one SBFD configuration cycle. Then, the network device can send a maximum of multiple first DCIs within one SBFD configuration cycle, and the contents indicated by the multiple first DCIs can be the same or different. For example, the network device sends multiple first DCIs within one SBFD configuration cycle, and the contents indicated by the first part of the multiple first DCIs are the same or different, and the contents indicated by the second part of the first DCIs are the same. The content indicated by the second part of the first DCI is the same as the content indicated by the last first DCI in the first part of the DCI.

[0226] Specifically, the protocol constrains that a maximum of T (T is an integer greater than 1) first DCIs may be sent within an SBFD configuration cycle, and the indication content may be the same or different. Alternatively, within an SBFD cycle, there is no limit on the number of first DCIs. The indication content of the first DCIs from 1 to T may be the same or different. For each first DCI from T+1 onwards within the SBFD cycle, the content is constrained to be the same as that of the Tth first DCI. T is specified by the protocol or indicated by the network device.

[0227] In some embodiments, the network device may further receive feedback information sent by the terminal via a MAC CE, where the feedback information is used to indicate whether the first DCI is received.

[0228] In some embodiments, the network device may further perform one or more of the following steps:

[0229] If the canceled or disabled first SBFD symbol set includes a first target symbol, the first target symbol is a symbol configured (for example, through TDD-UL-DL-ConfigCommon) as a downlink symbol D or a flexible symbol F, and after determining that the first SBFD symbol set is canceled or disabled, the position corresponding to the first target symbol is the downlink symbol D; if the transmission direction configured in the symbol is uplink, the network device abandons reception or delays reception;

[0230] If the canceled or disabled first SBFD symbol set includes a second target symbol, the second target symbol is a symbol configured (for example, through TDD-UL-DL-ConfigCommon) as a flexible symbol F, and after determining that the first SBFD symbol set is canceled or disabled, the position corresponding to the second target symbol is an uplink symbol U; if the transmission direction configured in the symbol is downlink, the network device abandons reception or delays reception;

[0231] If the canceled or disabled first SBFD symbol set includes a third target symbol, the third target symbol is a symbol configured (for example, through TDD-UL-DL-ConfigCommon) as a flexible symbol F, after determining that the first SBFD symbol set is canceled or disabled, the position corresponding to the third target symbol is the F symbol, and conflict processing is performed according to the processing method for the F symbol;

[0232] If the canceled or disabled first SBFD symbol set includes a fourth target symbol, the fourth target symbol is a symbol configured (for example, through TDD-UL-DL-ConfigCommon configuration) as a flexible symbol F, and after determining that the first SBFD symbol set is canceled or disabled, the transmission direction on the frequency domain resources corresponding to the uplink subband in the fourth target symbol is downlink; if the transmission direction configured on the frequency domain resources corresponding to the uplink subband in the fourth target symbol is uplink, the network device abandons reception or delays reception.

[0233] In some embodiments, the network device may further receive third information sent by the network device and determine SBFD symbol configuration information based on the third information. The first SBFD symbol set includes all SBFD symbols within an SBFD symbol configuration period, and the SBFD symbol configuration period and all SBFD symbols within the SBFD symbol configuration period are determined based on the SBFD symbol configuration information.
