Description

Information processing method, device and readable storage medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 11, 2023, with application number 202311012531.8 and application name “An information processing method, device and readable storage medium”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to an information processing method, device, and readable storage medium. Background Art

[0003] Related technologies have proposed the research direction of non-overlapping sub-band full duplex (SBFD). This involves dividing frequency domain resources into multiple, non-overlapping sub-bands, with uplink and downlink frequency domain resources located in different sub-bands. To address the switching issue, base stations can avoid sending downlink signals or scheduling / configuring terminals to transmit uplink signals on symbols switching between traditional symbols (such as downlink symbols D, uplink symbols U, and flexible symbols F) and symbols containing uplink or downlink sub-bands (or simply SBFD symbols). However, this approach increases the scheduling complexity of the base station.

[0157] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0158] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0159] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0160] Embodiments of the present disclosure provide an information processing method and apparatus to reduce the complexity of network device scheduling.

[0161] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0162] Referring to FIG1 , FIG1 is a flowchart of an information processing method provided by an embodiment of the present disclosure, which is applied to a terminal and includes the following steps:

[0163] Step 101: Determine a first symbol set.

[0164] In which, the first symbol set is used for switching between SBFD symbols and traditional symbols, reserving switching time for terminals and / or network devices, that is, the first symbol set is used for switching SBFD symbols to traditional symbols, or the first symbol set is used for switching traditional symbols to SBFD symbols, and the traditional symbols include one or more of uplink symbols U, downlink symbols D and flexible symbols F.

[0165] In the embodiment of the present disclosure, the terminal may determine the first symbol set in multiple ways.

[0166] Method 1: Determine the first symbol set according to the protocol provisions.

[0167] The agreement stipulates that:

[0168] K symbols preceding a group of consecutive SBFD symbols are used as the first symbol set; or K symbols following a group of consecutive SBFD symbols are used as the first symbol set, where K is an integer greater than or equal to 0. The K value may be a predefined value, for example, the K value may be defined based on factors such as SCS (Subcarrier Spacing), FR1 (Frequency Range 1), FR2 (Frequency Range 2), and / or a switching position.

[0169] For example, the first symbol set may be the K symbols before a group of consecutive SBFD symbols, for example, symbols nK, n-K+1,…, n-1, where n is the position of the first SBFD symbol in a group of consecutive SBFD symbols; or, the first symbol set may be: the K symbols after a group of consecutive SBFD symbols are the first symbol set, for example, symbols n+1, n+2,…, n+K, where n is the position of the last SBFD symbol in a group of SBFD symbols.

[0170] In an embodiment of the present disclosure, the K symbols of the first symbol set include:

[0171] Symbols configured as downlink symbols D and / or uplink symbols U. For example, symbols configured as downlink symbols D and / or uplink symbols U by the cell-level common configuration tdd-UL-DL-ConfigurationCommon; and / or symbols configured as downlink symbols D and / or uplink symbols U by the terminal-level configuration tdd-UL-DL-ConfigurationDedicated.

[0172] In a second method, the terminal determines the first symbol set according to the instructions of the network device (such as the base station) and the protocol provisions. This method may include any of the following methods:

[0173] 2.1. In this method, a terminal receives first information sent by a network device, where the first information indicates the number K of symbols in the first symbol set, and obtains the position of the first symbol set specified by the protocol, where the position of the first symbol set includes either before a group of consecutive SBFD symbols or after a group of consecutive SBFD symbols. The terminal then determines, based on the number K of symbols and the position of the first symbol set, that the K symbols before a group of consecutive SBFD symbols constitute the first symbol set, or that the K symbols after a group of consecutive SBFD symbols constitute the first symbol set, where K is an integer greater than or equal to 0.

[0174] The network device may send the first information via Radio Resource Control (RRC) signaling.

[0175] 2.2. In this method, the terminal receives third information sent by the network device and obtains the position of the first symbol set specified by the protocol. The position of the first symbol set includes either before a group of consecutive SBFD symbols or after a group of consecutive SBFD symbols. The third information is used to determine a first parameter, which is used to determine the number K of symbols in the first symbol set. Subsequently, based on the number K and the position of the first symbol set, the terminal may use the K symbols before a group of consecutive SBFD symbols as the first symbol set, or the K symbols after a group of consecutive SBFD symbols as the first symbol set. K is an integer greater than or equal to 0.

[0176] For example, the third information may include information about the first parameter, and the terminal determines the first parameter based on the third information. Assuming that the first parameter is α, for example, the number of symbols K in the first symbol set is Where T is the symbol length, Indicates rounding up. For another example, the number of symbols K in the first symbol set is Among them, T is the symbol length, N TA,offsetDetermined by n-TimingAdvanceOffset or according to the protocol, Indicates rounding up.

[0177] The method for obtaining K is the same as that in Method 1, and the contents of the K symbols of the first symbol set are the same as those in Method 1. The network device may send the third information through RRC signaling.

[0178] In a third approach, the terminal determines the first symbol set according to an instruction from a network device (such as a base station).

[0179] In this manner, the terminal may receive second information sent by the network device and determine the first symbol set based on the second information, wherein the second information is used to indicate the position of each symbol included in the first symbol set. The network device may send the second information via RRC signaling.

[0180] In some embodiments, the second information may further indicate information of the SBFD symbol, so that the terminal can accurately determine the first symbol set, wherein the contents of the K symbols of the first symbol set are the same as those in the first method.

[0181] In some embodiments of the present disclosure, the terminal may further receive fourth information sent by a network device, where the fourth information indicates information about SBFD symbols. The terminal may then determine the group of consecutive SBFD symbols based on the fourth information, thereby facilitating the terminal determining the positions of the K symbols. The network device may send the fourth information via RRC signaling or other means.

[0182] Step 102: Determine the validity of a sending opportunity and / or a receiving opportunity according to the first symbol set.

[0183] Here, determining the validity of the sending timing and / or receiving timing can also be understood as determining whether the sending timing and / or receiving timing is valid, for example, whether data can be sent at the sending timing and received at the receiving timing.

[0184] In the embodiment of the present disclosure, the terminal may determine the validity in one or more of the following ways:

[0185] If at least one symbol corresponding to the sending opportunity and / or receiving opportunity overlaps with at least one symbol of the first symbol set, discarding or delaying the sending opportunity and / or receiving opportunity;

[0186] If at least one symbol corresponding to a transmission opportunity and / or a reception opportunity overlaps with at least one symbol of the first symbol set, performing rate matching on a portion of the transmission opportunity and / or the reception opportunity that does not overlap with the first symbol set;

[0187] If the transmission opportunity partially or completely overlaps with the H symbols following the first symbol set (i.e., the first H symbols of a group of consecutive SBFD symbols), discarding or delaying the transmission opportunity;

[0188] If at least one symbol corresponding to the transmission opportunity overlaps with H symbols following the first symbol set (i.e., the first H symbols of a group of consecutive SBFD symbols), rate matching is performed on a target symbol, where the target symbol is a symbol that does not overlap with the transmission opportunity, the first symbol set, and the H symbols;

[0189] The receiving opportunity is valid on the M symbols after the first symbol set (that is, the first M symbols of a group of consecutive SBFD symbols);

[0190] Wherein, H and M are specified by the protocol or notified to the terminal by the network device, and H and M are integers greater than or equal to 0.

[0191] In some embodiments, the terminal may further determine that N symbols following the set of consecutive SBFD symbols are valid for transmission; where N is specified by the protocol or notified to the terminal by the network device, and N is an integer greater than or equal to 0. The terminal may transmit an uplink on these N symbols, and the uplink may be dynamically configured and / or configured by a higher layer.

[0192] In the embodiment of the present disclosure, H, K, M, N, etc. can take values ​​of 0, 1, 2, 3 or 4, etc.

[0193] In the embodiment of the present disclosure, since the terminal can determine the validity of the sending timing and / or receiving timing based on the determined first symbol set, even if the network device configures or schedules uplink transmission or downlink reception for the terminal on the determined first symbol set, the terminal may not send uplink or receive downlink, thereby solving the problem of switching between symbols and reducing the complexity of network device scheduling.

[0194] 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:

[0195] Step 201: Determine a first symbol set, and / or send indication information to a terminal, wherein the indication information is used to determine the first symbol set.

[0196] The first symbol set is used for switching between SBFD symbols and traditional symbols, and the traditional symbols include one or more of uplink symbols U, downlink symbols D and flexible symbols F.

[0197] Specifically, the network device may determine the first symbol set according to a protocol provision, where the protocol provision includes:

[0198] K symbols preceding a group of consecutive SBFD symbols are used as the first symbol set; or K symbols following a group of consecutive SBFD symbols are used as the first symbol set, where K is an integer greater than or equal to 0. The value of K may be a predefined value, or may be defined based on factors such as SCS, FR1, FR2, and / or a switching position.

[0199] Specifically, the indication information may include first information, second information, third information, etc.

[0200] For example, the network device may send first information to the terminal, where the first information is used to indicate the number K of symbols in the first symbol set.

[0201] Alternatively, the network device may send second information to the terminal, where the second information is used to indicate the position of each symbol included in the first symbol set. In some embodiments, the second information is further used to indicate information of an SBFD symbol.

[0202] Alternatively, the network device may send third information to the terminal, where the third information is used to determine a first parameter, and the first parameter is used to determine the number K of symbols in the first symbol set; wherein K is an integer greater than or equal to 0.

[0203] In some embodiments, the network device may further send fourth information to the terminal, where the fourth information is used to indicate information of the SBFD symbol.

[0204] The contents of the K symbols of the first symbol set may refer to the description of the aforementioned embodiment.

[0205] Step 202: Determine the validity of a sending opportunity and / or a receiving opportunity according to the first symbol set.

[0206] In the embodiment of the present disclosure, the network device may determine the validity in one or more of the following ways:

[0207] If at least one symbol corresponding to the sending opportunity and / or receiving opportunity overlaps with at least one symbol of the first symbol set, discarding or delaying the sending opportunity and / or receiving opportunity;

[0208] If at least one symbol corresponding to a transmitting opportunity and / or a receiving opportunity overlaps with at least one symbol of the first symbol set, performing rate matching on a portion of the transmitting opportunity and / or the receiving opportunity that does not overlap with the first symbol set;

[0209] If the receiving opportunity partially or completely overlaps with H symbols following the first symbol set (i.e., the first H symbols of a group of consecutive SBFD symbols), discarding or delaying the receiving opportunity;

[0210] If at least one symbol corresponding to the receiving opportunity overlaps with H symbols following the first symbol set (i.e., the first H symbols of a group of consecutive SBFD symbols), rate matching is performed on a target symbol, where the target symbol is a symbol that does not overlap with the transmitting opportunity, the first symbol set, and the H symbols;

[0211] The transmission opportunity is valid on the M symbols after the first symbol set (that is, the first M symbols of a group of consecutive SBFD symbols);

[0212] In some embodiments, the network device may further determine that a reception opportunity is valid N symbols following the group of consecutive SBFD symbols, where N is specified by the protocol or notified to the terminal by the network device, and N is an integer greater than or equal to 0. The network device may receive an uplink transmission sent by the terminal during these N symbols. The uplink transmission may be dynamically configured by the network device and / or configured to the terminal by the network device via a higher layer.

[0213] Wherein, H and M are specified by the protocol or notified to the terminal by the network device, and H and M are integers greater than or equal to 0. H, K, M, N, etc. can take values ​​of 0, 1, 2, 3 or 4, etc.

[0214] In the embodiment of the present disclosure, since the terminal can determine the validity of the sending timing and / or receiving timing based on the determined first symbol set, even if the network device configures or schedules uplink transmission or downlink reception for the terminal on the determined first symbol set, the terminal may not send uplink or receive downlink, thereby solving the problem of switching between symbols and reducing the complexity of network device scheduling.

[0215] The following describes the specific implementation process of the embodiments of the present disclosure in combination with different embodiments. In particular, the network device is described by taking a terminal as an example.

[0216] In one embodiment of the present disclosure, the terminal switches from uplink symbols U to SBFD symbols.

[0217] In this embodiment, the protocol may specify that the K symbols preceding a group of consecutive SBFD symbols are defined as a first symbol set, for example, symbols nK, n-K+1, ..., n-1, where n is the position of the first SBFD symbol in the group of consecutive SBFD symbols. For example, the protocol specifies that the K symbols corresponding to T_switch in Figure 3 are defined as the first symbol set. The terminal and the base station determine the first symbol set according to the protocol.

[0218] Alternatively, the base station indicates through RRC signaling that the number of symbols in the first symbol set is K. The protocol specifies that the K symbols preceding a group of consecutive SBFD symbols are the first symbol set. For example, the K symbols corresponding to T_switch in FIG3 are the first symbol set. The terminal determines the first symbol set based on the value of K and the positions of the K symbols specified in the protocol.

[0219] Alternatively, the base station indicates third information through RRC signaling, and the third information is used to determine a parameter α, and the parameter α is used to determine the number of symbols K of the first symbol set. The protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set. The terminal determines the first symbol set according to the parameter α and the protocol. For example, the number of symbols K of the first symbol set is Where T is the symbol length. For another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offset Determined by n-TimingAdvanceOffset or according to the table in the protocol.

[0220] Alternatively, the base station indicates the position of each symbol included in the first symbol set through RRC signaling. For example, the base station may further configure the first symbol set in the symbol configured as D, U, or F through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. For example:

[0221] TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated configure slot n+5 to D. The base station further indicates the symbols in slot n+5 in Figure 3 as {TTXXXXX XXXXXXX} through RRC signaling, where {TT} represents the first symbol set and X represents SBFD symbols. The terminal determines the first symbol set based on the base station RRC signaling instructions. In Figure 3, the transition time configured by the base station does not include the TA-offset time.

[0222] If the sending / receiving opportunity partially or completely overlaps with the first symbol set, the terminal discards the sending / receiving opportunity, delays the sending / receiving opportunity, or performs rate matching on the part where the sending / receiving opportunity does not overlap with the first symbol set.

[0223] Taking into account that the transmission on the uplink subband has a timing advance, in order to avoid the transmission on the uplink subband arriving at the base station in advance and compressing the base station switching time, it can be considered that the first H symbols of the SBFD symbol are not used for uplink transmission, such as the H symbols corresponding to TA-offset in the frame format diagram of Figure 3. Alternatively, when the first symbol set configured by the base station is long enough, even if the transmission on the uplink subband has a timing advance, the base station still has sufficient switching time. At this time, it can be considered to use the last M symbols in the first symbol set (that is, the M symbols before a group of consecutive SBFD symbols) for downlink transmission, such as the M symbols indicated by 41 in Figure 4, thereby improving resource utilization. In Figure 4, the switching time configured by the base station includes the time of TA-offset.

[0224] In some embodiments, considering that transmissions on the uplink subband have a timing advance, it may be considered that the terminal may transmit uplink signals N symbols after a group of consecutive SBFD symbols. For example, in the frame formats of Figures 3 and 4 , because of the timing advance (indicated by 32 in Figure 3 and 43 in Figure 4 ), this portion of transmission arrives at the base station aligned with the downlink timing and may not compress the switching time from SBFD to U. Allowing uplink transmissions N symbols after a group of consecutive SBFD symbols can effectively utilize resources.

[0225] In some embodiments, on the terminal side, the terminal can determine whether it can transmit uplink on the resources indicated by 31 in Figure 3 and the resources indicated by 42 in Figure 4 based on its own switching time requirements and / or the switching time requirements of the base station. The switching time requirements of the base station may be specified by the protocol or notified by the base station.

[0226] In one embodiment of the present disclosure, the terminal switches from the downlink symbol D to the SBFD symbol.

[0227] A protocol may define the K symbols preceding a group of consecutive SBFD symbols as a first symbol set, for example, nK, n-K+1, ..., n-1, where n is the position of the first SBFD symbol in the group of consecutive SBFD symbols. For example, a protocol defines the K symbols corresponding to T_Switch in FIG. 5 as the first symbol set. The terminal and the base station determine the first symbol set according to the protocol.

[0228] Alternatively, the base station indicates through RRC that the number of symbols in the first symbol set is K. The protocol specifies that the K symbols preceding a group of consecutive SBFD symbols are the first symbol set. For example, the K symbols corresponding to T_switch in FIG5 are the first symbol set. The terminal determines the first symbol set based on the value of K and the positions of the K symbols specified in the protocol.

[0229] Alternatively, the base station indicates third information through RRC signaling, and the third information is used to determine a parameter α, and the parameter α is used to determine the number of symbols K of the first symbol set. The protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set. The terminal determines the first symbol set according to the parameter α and the protocol. For example, the number of symbols K of the first symbol set is Where T is the symbol length. For another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offset Determined by n-TimingAdvanceOffset or according to the table in the protocol.

[0230] Alternatively, the base station indicates the position of each symbol included in the first symbol set through RRC signaling. For example, the base station may further configure the first symbol set in the symbol configured as D, U, or F through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. For example:

[0231] TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated configure slot n+5 to D. The base station further indicates the symbols in slot n+5 in Figure 5 as {TTXXXXX XXXXXXX} through RRC signaling, where {TT} represents the first symbol set and X represents SBFD symbols. The terminal determines the first symbol set based on the base station RRC signaling instructions. In Figure 5, the transition time configured by the base station does not include the TA-offset time.

[0232] If the sending / receiving opportunity partially or completely overlaps with the first symbol set, the terminal discards the sending / receiving opportunity, delays the sending / receiving opportunity, or performs rate matching on the part where the sending / receiving opportunity does not overlap with the first symbol set.

[0233] Taking into account that the transmission on the uplink subband has a timing advance, in order to avoid the compression of the base station switching time caused by the transmission on the uplink subband arriving at the base station in advance, it can be considered that the first H symbols of the SBFD symbol are not used for uplink transmission, such as the H symbols corresponding to TA-offset in the frame format diagram of Figure 5. Alternatively, when the first symbol set configured by the base station is long enough, even if the transmission on the uplink subband has a timing advance, the base station still has sufficient switching time. At this time, it can be considered to use the last M symbols in the first symbol set (or the M symbols before a group of consecutive SBFD symbols) to receive downlink transmission, such as the M symbols corresponding to 61 in Figure 6, thereby improving resource utilization. In Figure 6, the switching time configured by the base station does not include the time of TA-offset.

[0234] In some embodiments, considering that transmissions on the uplink subband have a timing advance, it may be considered that the terminal may transmit uplink signals N symbols after a group of consecutive SBFD symbols, such as in the frame formats of Figures 5 and 6 (indicated by 51 in Figure 5 and 62 in Figure 6). Because of the timing advance, these transmissions will arrive at the base station aligned with the downlink timing and may not compress the switching time from SBFD to U. Allowing uplink transmissions N symbols after a group of consecutive SBFD symbols can effectively utilize resources.

[0235] In some embodiments, on the terminal side, the terminal can determine whether it can transmit uplink on Figure 5 (resources indicated by 52) and Figure 6 (resources indicated by 63) based on its own switching time requirements and / or the switching time requirements of the base station. The switching time requirements of the base station may be specified by the protocol or notified by the base station.

[0236] In one embodiment of the present disclosure, the terminal switches from the SBFD symbol to the D symbol.

[0237] In this embodiment, a protocol may define the K symbols following a group of consecutive SBFD symbols as a first symbol set, for example, symbols n+1, n+2, ..., n+K, where n is the position of the last SBFD symbol in the group. For example, the K symbols corresponding to T_Switch_1 in Figure 5 constitute the first symbol set. The terminal and base station determine the first symbol set according to the protocol.

[0238] Alternatively, the base station indicates through RRC that the number of symbols in the first symbol set is K. The protocol specifies that the K symbols following a group of consecutive SBFD symbols are the first symbol set. For example, the K symbols corresponding to T_switch_1 in Figure 7 are the first symbol set. The terminal determines the first symbol set based on the value of K and the positions of the K symbols specified in the protocol.

[0239] Alternatively, the base station indicates third information through RRC signaling, and the third information is used to determine a parameter α, and the parameter α is used to determine the number of symbols K of the first symbol set. The protocol stipulates that the K symbols before a group of consecutive SBFD symbols are the first symbol set. The terminal determines the first symbol set according to the parameter α and the protocol. For example, the number of symbols K of the first symbol set is Where T is the symbol length. For another example, the number of symbols K in the first symbol set is Where T is the symbol length, N TA,offset Determined by n-TimingAdvanceOffset or according to the table in the protocol.

[0240] Alternatively, the base station indicates the position of each symbol included in the first symbol set through RRC signaling. For example, the base station may further configure the first symbol set in the symbol configured as D, U, or F through tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. For example:

[0241] TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigurationDedicated configure slot n+2 to D. The base station further indicates the symbols in slot n+2 of Figure 7 as {TTXXXXX XXXXXXX} through RRC signaling, where {TT} represents the first symbol set and X represents the SBFD symbol. The terminal determines the first symbol set based on the base station RRC signaling instruction.

[0242] If the sending / receiving opportunity partially or completely overlaps with the first symbol set, the terminal discards the sending / receiving opportunity, delays the sending / receiving opportunity, or performs rate matching on the part where the sending / receiving opportunity does not overlap with the first symbol set.

[0243] It can be seen from the above description that the solution of the embodiment of the present disclosure can solve the problem of switching between SBFD and traditional symbols, thereby reducing the complexity of base station scheduling.
