[0003] In the 5th Generation mobile communication technology (5G) New Radio (NR), research is underway on non-overlapping subband full-duplex (SBFD) technology to improve uplink coverage in Time Division Duplex (TDD) systems. To reduce random access latency for terminals supporting SBFD, consideration is being given to supporting random access within SBFD symbols. Therefore, determining the random access opportunity (RO) resources for Physical Random Access Channel (PRACH) transmissions for SBFD-capable terminals is a pressing technical challenge.

[0111] 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.

[0112] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0113] 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.

[0114] It is worth noting that the technologies involved in the embodiments of the present disclosure include the following:

[0115] 1. Duplex mode

[0116] 5G NR supports TDD and frequency division duplex (FDD), which refer to two duplex communication modes in mobile communication technology. TDD stands for time division duplex, and FDD stands for frequency division duplex. TDD transmits and receives at different times on the same frequency channel (i.e., carrier), distinguishing uplink and downlink transmission resources by time. FDD transmits and receives simultaneously on different frequency channels, distinguishing uplink and downlink transmission resources by frequency.

[0117] 5G NR also supports full-duplex with non-overlapping subbands, that is, the base station can simultaneously transmit and receive through different subbands within a TDD carrier, and the subbands used for transmission and reception do not overlap. An SBFD symbol is a symbol that contains both a subband for uplink transmission and a subband for downlink transmission. Currently, only SBFD symbols can be configured in downlink symbols or flexible symbols configured in the TDD uplink and downlink common configuration (TDD-UL-DL-ConfigCommon). For sub-band full-duplex systems, the sub-band configurations currently considered for support (SBFD sub-band configuration #1, SBFD sub-band configuration #2) include the following two cases:

[0118] SBFD subband configuration #1 uses the {DUD} mode, that is, an SBFD timeslot contains an uplink subband at the center of the carrier bandwidth and two downlink subbands on both sides of the carrier bandwidth;

[0119] SBFD subband configuration #2 uses the {DU} mode, that is, one SBFD timeslot contains an uplink subband on one side of the carrier bandwidth and a downlink subband on the other side of the carrier bandwidth.

[0120] Terminals in the SBFD system are half-duplex terminals and can be either SBFD-supporting or non-SBFD-supporting terminals. SBFD-supporting terminals are terminals that are aware of the SBFD subband configuration, or are aware of the access base station's ability to perform SBFD operations, or are later-version terminals. For terminals that support SBFD, new terminal behaviors can be defined. Terminals that do not support SBFD are early terminals, or legacy terminals, or are unaware of the SBFD subband configuration, or are unaware of the access base station's ability to perform SBFD operations. SBFD-supporting terminals (i.e., SBFD-supporting terminals) will be referred to as SBFD terminals.

[0121] 2. PRACH transmission

[0122] In a TDD system of the related art, a valid RO in a PRACH resource can only appear in a flexible symbol F or an uplink symbol U, and all ROs in a downlink symbol are invalid ROs.

[0123] Specifically, methods for determining effective RO in related technologies include:

[0124] All ROs on an FDD carrier or a supplementary uplink (SUL) carrier are valid ROs.

[0125] For TDD carriers, whether a RO is valid is determined as follows:

[0126] If the UE is not configured with TDD-UL-DL-ConfigurationCommon, then in a PRACH slot, a RO is considered valid if it does not precede a synchronization signal block (SSB) and is at least N symbols after the last SSB symbol, where N is an integer whose value depends on the subcarrier spacing of the PRACH sequence. If the UE is configured with channelAccessMode="semiStatic", in addition to the conditions described above, the RO must not overlap with a group of consecutive symbols before the start of the next channel occupation time when the UE is not transmitting.

[0127] If the UE is configured with TDD-UL-DL-ConfigurationCommon, the RO in the uplink symbol is valid RO, or in a PRACH timeslot, when the RO is not before the SSB and is at least N symbols after the last downlink symbol and at least N symbols after the last SSB symbol, it is valid RO, where N is an integer whose value depends on the subcarrier spacing of the PRACH sequence; if the UE is configured with channelAccessMode="semiStatic", in addition to the conditions described above, the RO must not overlap with a group of consecutive symbols before the start of the next channel occupation time when the UE is not transmitting.

[0128] In the embodiment of the present disclosure, the time unit may be a symbol, a time slot, etc.

[0129] The present disclosure provides a transmission processing method and apparatus. The method and apparatus are based on the same patent application concept. Since the method and apparatus solve similar problems, the implementation of the apparatus and method can refer to each other, and the repetitive parts will not be repeated.

[0130] As shown in FIG1 , a transmission processing method provided by an embodiment of the present disclosure includes:

[0131] Step 101: A terminal receives first configuration information sent by a network-side device, where the first configuration information is used to configure a first physical random access channel (PRACH) resource supporting a full-duplex SBFD terminal with non-overlapping subbands.

[0132] Step 102: The terminal determines a first random access opportunity (RO) corresponding to the first PRACH resource.

[0133] Step 103: The terminal determines whether the first RO is a valid RO according to the type of the time unit where the first RO is located;

[0134] The types of the time units include SBFD time units and non-SBFD time units. Alternatively, the types of the time units are SBFD time units and non-SBFD time units in the downlink symbols configured by TDD-uplink (UL)-downlink (DL)-common configuration (ConfigCommon), and SBFD time units in the downlink symbols configured by non-TDD-UL-DL-ConfigCommon. In this embodiment, only the types of the time units as SBFD time units and non-SBFD time units are used for explanation, but it should be clear that the case where the type of the time unit is an SBFD time unit can be limited to the SBFD time unit in the downlink symbols configured by TDD-UL-DL-ConfigCommon, and the case where the type of the time unit is a non-SBFD time unit can be limited to the SBFD time unit in the downlink symbols configured by non-TDD-UL-DL-ConfigCommon.

[0135] In this way, according to the above steps 101-103, the terminal can receive the first configuration information sent by the network side. Since the first configuration information is used to configure the first PRACH resource of the terminal supporting SBFD, after determining the first RO corresponding to the first PRACH resource, it can be determined whether the first RO is a valid RO based on whether the time unit in which the first RO is located is an SBFD time unit or a non-SBFD time unit, so as to ensure that subsequent PRACH transmission is valid.

[0136] It should be noted that, in this embodiment, the first configuration information is configuration information for terminals supporting SBFD. The network-side device will send the first configuration information to terminals supporting SBFD, or only terminals supporting SBFD can receive the first configuration information.

[0137] In one embodiment, a network-side device sends specific signaling that carries the first configuration information or information indicating the first configuration information. Accordingly, the terminal receives the specific signaling and the first configuration information. The specific signaling can be understood as signaling for configuring the first PRACH resource.

[0138] In addition, in this embodiment, a mapping relationship between the first PRACH resource and the first RO is predefined or configured. After the terminal learns the first PRACH resource by receiving the first configuration information, it can determine the first RO corresponding to the first PRACH resource according to the mapping relationship.

[0139] Furthermore, in some embodiments, the terminal determines whether the first RO is a valid RO according to the type of the time unit in which the first RO is located, including:

[0140] When the time unit where the first RO is located is a non-SBFD time unit, the terminal performs at least one of the following:

[0141] 1) determining the first RO as an invalid RO;

[0142] 2) determining whether the first RO is an invalid RO or a valid RO based on a temporal position relationship between the first RO and the second RO;

[0143] 3) determining whether the first RO is an invalid RO or a valid RO based on the number of the first ROs and the number of the second ROs;

[0144] 4) determining whether the first RO is an invalid RO or a valid RO based on a preset method;

[0145] The second RO is a valid RO corresponding to a second PRACH resource, and the second PRACH resource is configured by second configuration information.

[0146] In this way, for the first RO in the non-SBFD time unit, one or more of the above-mentioned methods may be used to determine whether the first RO is an invalid RO or a valid RO.

[0147] In this embodiment, for the first RO in the non-SBFD time unit, which of the above items is used to determine whether the first RO is an invalid RO or a valid RO can be determined based on at least one of the configuration of the network side device and the terminal capability.

[0148] Determining the first RO as an invalid RO may mean that the first ROs of all non-SBFD time units are invalid ROs, that is, all first ROs configured in non-SBFD time units are invalid ROs. Assuming that the time unit is a time slot, a terminal supporting SBFD determines a first PRACH resource based on the first configuration information. When the time slot where the RO corresponding to the first PRACH resource is located contains a symbol type of non-SBFD symbol, all ROs are considered invalid ROs. As shown in Figure 2, in the uplink time slots configured by TDD-UL-DL-ConfigCommon (all non-SBFD symbols), the ROs contained in the first PRACH resource are all invalid ROs, and the first ROs in time slots (slot) 3, slot 4, slot 8, and slot 9 are invalid ROs.

[0149] Of course, specific conditions may also be set to define the first RO that meets the specific conditions in a non-SBFD time unit as an invalid RO. The specific conditions may be a set time domain range or frequency domain range.

[0150] For the first RO of the non-SBFD time unit, it can also be determined as an invalid RO or a valid RO based on its time domain position relationship with the second RO; it can also be determined as an invalid RO or a valid RO based on its number and the number of second ROs; it can also be determined as an invalid RO or a valid RO based on a preset method.

[0151] For example, when the symbol type of the RO corresponding to the first PRACH resource is a non-SBFD symbol, it can be considered that the first RO whose time unit does not include the second RO is an invalid RO resource, and the first RO whose time unit includes the second RO can be further determined as an invalid RO or a valid RO based on the time domain position relationship or number or preset method between the two.

[0152] In some embodiments, the determining whether the first RO is an invalid RO or a valid RO based on the temporal position relationship between the first RO and the second RO includes:

[0153] 2-1) When any time subunit included in the first RO overlaps with any time subunit included in the second RO, the terminal determines that the first RO is an invalid RO; or,

[0154] In a case where any time subunit included in the first RO and any time subunit included in the second RO do not overlap, the terminal determines whether the first RO is an invalid RO or a valid RO based on a preset method.

[0155] Specifically, the temporal positional relationship between the first and second ROs refers to whether their time subunits overlap. Thus, for a first RO in a non-SBFD time unit, if any of its time subunits overlaps with any of the second RO's time subunits, the first RO can be determined to be invalid. If any of its time subunits do not overlap with any of the second RO's time subunits, whether the first RO is invalid or valid can be further determined based on a preset method.

[0156] Here, the overlapping of time sub-units includes: overlapping of time domain resources, or overlapping of time domain and frequency domain resources.

[0157] In this embodiment, a first RO within a time unit includes one or more time subunits. For example, a first RO within a time slot includes one or more symbols. Therefore, a terminal supporting SBFD determines a first PRACH resource based on the first configuration information. When the time slot in which the RO corresponding to the first PRACH resource includes non-SBFD symbols, if any symbol included in the first RO overlaps with any symbol included in the second RO, the RO is considered invalid. Otherwise, whether the RO is valid is determined based on a preset method.

[0158] As shown in Figures 3 and 4, in the uplink time slots configured by TDD-UL-DL-ConfigCommon (all non-SBFD symbols), any symbol contained in the first RO in time slots 3 and 8 does not overlap with the second RO, and is determined to be a valid RO based on a preset method, then it is considered to be a valid RO;

[0159] If the overlap of the time sub-units is only an overlap of time domain resources, since the symbols included in the first RO in time slots 4 and 9 and the symbols included in the second RO overlap in the time domain, it is considered to be an invalid RO, as shown in Figure 3; if the overlap of the time sub-units includes an overlap of time domain and frequency domain resources, since the symbols included in the first RO in time slots 4 and 9 and the symbols included in the second RO overlap in the time domain, there is no overlap in frequency domain resources, and it is determined to be a valid RO based on a preset method, it is considered to be a valid RO, as shown in Figure 4.

[0160] In some embodiments, the determining whether the first RO is an invalid RO or a valid RO based on the temporal position relationship between the first RO and the second RO includes:

[0161] 2-2) When the time unit where the first RO is located overlaps with the time unit where the second RO is located, the terminal determines that the first RO is an invalid RO; or,

[0162] In a case where the time unit where the first RO is located does not overlap with the time unit where the second RO is located, the terminal determines whether the first RO is an invalid RO or a valid RO based on a preset method.

[0163] Specifically, the temporal positional relationship between the first and second ROs refers to whether the time periods of the first and second ROs overlap. Thus, for a first RO in a non-SBFD time unit, if its time unit overlaps with the time unit of the second RO, the first RO can be determined to be invalid. If its time unit does not overlap with the time unit of the second RO, whether the first RO is invalid or valid can be further determined based on a preset method.

[0164] Assuming that the time unit is a time slot, a terminal supporting SBFD determines the first PRACH resource based on the first configuration information. When the time slot containing the first RO corresponding to the first PRACH resource contains a non-SBFD symbol, if the time slot containing the first RO overlaps with the time slot containing the second RO, it is considered an invalid RO; otherwise, whether it is a valid RO is determined based on a preset method. As shown in Figure 5, in the uplink time slots configured by TDD-UL-DL-ConfigCommon (all non-SBFD symbols), the time slot containing the first RO in time slots 3 and 8 does not overlap with the time slot containing the second RO, and is determined to be a valid RO based on the preset method, then the first RO in time slots 3 and 8 is considered to be a valid RO; if the time slot containing the first RO in time slots 4 and 9 overlaps with the time slot containing the second RO, it is considered to be an invalid RO.

[0165] In some embodiments, the determining whether the first RO is an invalid RO or a valid RO based on the number of the first ROs and the number of the second ROs includes:

[0166] In a case where the total number of the first RO and the third RO is greater than or equal to (or greater than) a first threshold, the terminal determines that the first RO is an invalid RO; or,

[0167] When the total number of the first RO and the third RO is less than (or less than or equal to) the first threshold, the terminal determines that the first RO is a valid RO;

[0168] The third RO is an RO in the second RO that overlaps with the first RO in time domain; or the third RO is an RO in the second RO that is in the same time unit as the first RO.

[0169] That is, for the first RO in a non-SBFD time unit, if the sum of the first and third ROs is greater than or equal to a first threshold, the first RO is determined to be invalid; if the sum of the first and third ROs is less than the first threshold, the first RO is determined to be valid. Here, the first threshold is predefined or configured.

[0170] If the third RO is an RO in the second RO that is in the same time unit as the first RO, then the third RO and the second RO may overlap in time domain or may not overlap in time domain.

[0171] In addition, for counting the first ROs, an independent counting method can be adopted, that is, each first RO is counted, and the number of first ROs is the number of all first ROs. Assuming that the time unit is a time slot, the number of first ROs in a time slot is 6 as shown in Figure 6; or, counting can be performed based on the time domain (different time units are located), that is, first ROs in different time units are counted, and the number of first ROs is the number of first ROs whose time units do not overlap, and multiple first ROs in the same time unit are recorded as 1. Assuming that the time unit is a time slot, the number of first ROs in a time slot is 1 as shown in Figure 6; or, counting can be performed based on the frequency domain (non-overlapping frequency domains), that is, first ROs that do not overlap in frequency domains are counted, and the number of first ROs is the number of first ROs in different frequency domains. Assuming that the time unit is a time slot, the number of first ROs in a time slot is 6 as shown in Figure 6.

[0172] The counting of the third RO can also adopt the method of the first RO described above, which will not be described in detail here.

[0173] Assuming that the time unit is a time slot, a terminal supporting SBFD determines a first PRACH resource based on the first configuration information. When the time slot in which the RO corresponding to the first PRACH resource is located contains a non-SBFD symbol, whether the first RO is a valid RO is determined based on whether the total number of the first RO and the third RO in the frequency domain is greater than or equal to a first threshold M1. As shown in Figure 6, when the predefined or configured M1 value is 8, in the uplink time slots configured by TDD-UL-DL-ConfigCommon (all non-SBFD symbols), there is no third RO in time slot 3. The first RO is determined to be a valid RO based on a preset method, and it is considered that all first ROs in time slot 3 are valid ROs; the total number of the first RO and the third RO in the frequency domain in time slot 4 is 10, which is greater than the predefined or configured M1. Therefore, all first ROs in time slot 4 are invalid ROs.

[0174] A terminal supporting SBFD determines a first PRACH resource based on the first configuration information. When the symbol type contained in the time slot where the first RO corresponding to the first PRACH resource is located is a non-SBFD symbol, whether the first RO is a valid RO is determined based on whether the total number of the first RO and the third RO in the time domain in one time slot is greater than or equal to the first threshold M2. If the predefined or configured M2 value is 2, then in an uplink time slot configured by TDD-UL-DL-ConfigCommon (all non-SBFD symbols),

[0175] If the total number of the first RO and the third RO in a time slot is 4, which is greater than the predefined or configured M2, the first RO of the time slot is an invalid RO, wherein the symbols of the two first ROs in the time slot are different and the symbols of the two third ROs are different;

[0176] If the total number of the first RO and the third RO in a time slot is 2, which is less than the predefined or configured M2, the first RO in the time slot is an invalid RO.

[0177] In one embodiment, whether to use mode 1) or mode 2-1) is determined based on the configuration of the network side device and / or the capability of the terminal; whether to use mode 2-1) or mode 4) is determined based on the configuration of the network side device and / or the capability of the terminal; whether to use mode 1) or mode 2-2) is determined based on the configuration of the network side device and / or the capability of the terminal; whether to use mode 2-2) or mode 4) is determined based on the configuration of the network side device and / or the capability of the terminal; and whether mode 3) and mode 4) are used in combination based on the configuration of the network side device and / or the capability of the terminal.

[0178] It should also be noted that, in this embodiment, the preset manner for determining whether the first RO is an invalid RO or a valid RO is a manner for determining whether the RO corresponding to the second PRACH resource is an invalid RO or a valid RO.

[0179] Specifically, the preset method is:

[0180] If the UE is not configured with TDD-UL-DL-ConfigurationCommon, then in a PRACH slot, the first RO is considered valid if it does not precede an SSB and is at least N symbols after the last SSB symbol, where N is an integer whose value depends on the subcarrier spacing of the PRACH sequence. If channelAccessMode="semiStatic" is configured, in addition to the conditions described above, the first RO must not overlap with a group of consecutive symbols before the start of the next channel occupation time when the UE is not transmitting.

[0181] If the UE is configured with TDD-UL-DL-ConfigurationCommon, the first RO in an uplink symbol is a valid RO, or in a PRACH timeslot, the first RO is a valid RO when it is not before the SSB and is at least N symbols after the last downlink symbol and at least N symbols after the last SSB symbol, where N is an integer whose value depends on the subcarrier spacing of the PRACH sequence; if the UE is configured with channelAccessMode="semiStatic", in addition to the conditions described above, the first RO must not overlap with a group of consecutive symbols before the start time of the next channel occupation time when the UE does not transmit.

[0182] In the above preset manner, the PRACH time slot is the time slot of the first PRACH.

[0183] In addition, in some embodiments, the terminal determines whether the first RO is a valid RO according to the type of the time unit in which the first RO is located, including:

[0184] When the time unit where the first RO is located is an SBFD time unit, the terminal determines that a valid RO satisfies at least one of the following:

[0185] 1') is located in the uplink sub-band;

[0186] 2') does not overlap with the switching time between the SBFD time unit and the non-SBFD time unit;

[0187] 3′) located after the target time unit and having a gap with the target time unit greater than or equal to a third threshold, the target time unit being the last full downlink time unit indicated by the time division multiplexing uplink and downlink configuration information;

[0188] 4') does not overlap with the time unit carrying SSB;

[0189] 5′) located after the time unit of the target SSB, and the interval between the time unit of the target SSB is greater than or equal to a fourth threshold, and the SSB is the SSB closest to the first RO;

[0190] 6') does not precede any time unit carrying an SSB in the PRACH time slot.

[0191] In this way, for the first RO of the SBFD time unit, the first RO can be determined to be a valid RO by satisfying one or more of the above conditions.

[0192] For example, the first RO that satisfies the combination of 1′) and 2′) above (for the case where the switching time is explicitly defined in the protocol) is a valid RO, ie

[0193] If the first RO is entirely located in the uplink subband and the first RO does not overlap with the switching time between the SBFD symbol and the non-SBFD symbol, it is a valid RO, otherwise it is an invalid RO;

[0194] The first RO satisfies the combination of 1') and 3') above and is a valid RO.

[0195] When tdd-UL-DL-ConfigurationCommon is not configured, if the first RO is entirely located in the uplink subband, it is a valid RO, otherwise it is an invalid RO; when tdd-UL-DL-ConfigurationCommon is configured, if all RO resources are located in the uplink subband and the RO resource is at least M symbols after the last full downlink symbol, it is a valid RO, otherwise it is an invalid RO;

[0196] The first RO satisfies the combination of 1'), 3') and 4') above and is a valid RO;

[0197] The first RO satisfies the combination of 1'), 3'), 5') and 6') above and is a valid RO.

[0198] Among them, the time unit carrying SSB is a time unit carrying SSB that cannot perform uplink reception.

[0199] In some embodiments, the method further comprises:

[0200] The terminal sends a PRACH on the valid RO.

[0201] That is, after determining a valid RO of the first RO, the terminal may transmit the PRACH in the valid RO.

[0202] In summary, the method of the embodiment of the present disclosure, for the SBFD terminal, configures the first PRACH resource through the first configuration information, and determines whether it is a valid RO resource based on the time unit type of the first RO, laying the foundation for subsequent PRACH transmission and ensuring the effectiveness of PRACH transmission.

[0203] As shown in FIG7 , the embodiment of the present disclosure further provides a transmission processing method, including:

[0204] Step 701: A network-side device sends first configuration information to a terminal, where the first configuration information is used to configure a first physical random access channel (PRACH) resource supporting a full-duplex (SBFD) terminal with non-overlapping subbands.

[0205] Step 702: The network-side device determines a first random access opportunity (RO) corresponding to the first PRACH resource.

[0206] Step 703: The network-side device determines whether the first RO is a valid RO according to the type of the time unit in which the first RO is located.

[0207] The types of the time unit include SBFD time unit and non-SBFD time unit.

[0208] According to the above steps 701-703, the network-side device sends the first configuration information to the terminal, so that the terminal and the network-side device can determine the first PRACH resource and the first RO corresponding to the first PRACH resource according to the first configuration information. Thereafter, it can be determined whether the first RO is a valid RO based on whether the time unit in which the first RO is located is an SBFD time unit or a non-SBFD time unit, so as to ensure that subsequent PRACH transmission is valid.
