Further, a plurality of systems can be combined (for example, combination of LTE and NR).

[0094] To improve UL coverage and throughput, subband full duplex (SBFD) will be studied in the duplex enhancement project. Specifically, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain on the downlink (DL) or flexible (F) symbols. Multiple SBs, including one uplink (UL) SB and at least one DL SB, can be used by the base station to transmit DL signals in the DL SB and receive UL signals in the UL SB at the same time. The DL symbol or the F symbol is configured by the time division duplex uplink-downlink common configuration (TDD-UL-DL-ConfigCommon) or the time division duplex uplink-downlink dedicated configuration (TDD-UL-DL-ConfigDedicated) or the down control information (DCI) format 2-0 to be a DL or F symbol. A symbol that simultaneously contains a DL SB and a UL SB in the frequency domain can be referred to as an SBFD symbol. Similarly, a time slot that includes at least one SBFD symbol in the multiple symbols included in the time slot can be referred to as an SBFD time slot. As shown in FIG. 1B, time slot #0 is a DL time slot, including 14 DL symbols, and time slots #1-3 are SBFD time slots, each including 14 SBFD symbols. Time slot #4 is a UL time slot and includes 14 UL symbols. Between the DL SB and the UL SB, there can also be a guard band (GB) to reduce interference between the DL signals in the DL SB and the UL signals in the UL SB through frequency domain isolation.

[0095] In a subband full duplex (SBFD) symbol, the GB and the DL SB are not available for UL transmission, and the UL SB is available for UL transmission. In an SBFD symbol, the frequency domain range available for UL transmission can be referred to as the UL available frequency domain range, and the frequency domain range unavailable for UL transmission can be referred to as the UL unavailable frequency domain range. According to the above analysis, the UL frequency domain range of the non-SBFD symbol and the SBFD symbol is different. The UL available frequency domain range is the UL frequency domain range on the CC. In an SBFD symbol, the UL available frequency domain range on the UL BWP refers to the frequency domain range overlapping the UL available frequency domain range on the CC. Unless otherwise specified, the UL available frequency domain range in the following refers to the UL available frequency domain range on the BWP. As shown in FIG. 1C, the DL time slot is divided into a DL subband (SB), a UL SB, and a DL SB. The UL SB can be configured with an RO.

[0096] There can also be a guard band (GB) between the DL subband and the UL subband to reduce the interference between the DL signal in the DL subband and the UL signal in the UL subband by frequency domain isolation.

[0097] In the SBFD symbol, the frequency domain range available for UL transmission can not be continuous, including the following two cases: the GB and the DL subband are not available for UL transmission, and the UL subband is available for UL transmission; the DL subband is not available for UL transmission, and the UL subband and the GB are available for UL transmission.

[0098] The frequency domain range available for UL transmission in the SBFD symbol can be referred to as the UL frequency domain range, and the frequency domain range not available for UL transmission in the SBFD symbol can be referred to as outside the UL frequency domain range. As known from the above, the UL frequency domain range of the non-SBFD symbol and the SBFD symbol is different. The UL frequency domain range is the UL frequency domain range on the CC. In the SBFD symbol, the UL frequency domain range on the UL BWP refers to the frequency domain range overlapping the UL frequency domain range on the CC. Unless otherwise specified, the UL frequency domain range in the following refers to the UL frequency domain range on the BWP.

[0099] In the idle state, the UE measures the received signal strength of the synchronization signal and (Physical Bradcast Channne, PBCH) block (SSB) beam and other information during the initial access to the cell, and selects the optimal SSB beam. In the direction of the optimal SSB beam, the PRACH signal is sent in the valid random access channel occasion (RACH Occasion, RO) to perform random access. The valid RO refers to the RO configured according to the criteria in the protocol. In addition, in other states, the UE can also send the PRACH signal in the valid RO to perform random access. Random access includes CBRA (Contention-Based Random Access) and CFRA (Contention-Free Random Access), wherein in CBRA, there are multiple UE using the same preamble sequence (preamble) case, i.e., the PRACH signals of 2 UEs collide, which will cause random access failure.

[0100] The time domain position of the RO can be determined according to the index prach-ConfigurationIndex and Table 1.

[0101] prach-ConfigurationIndex INTEGER (0..255);

[0102] PRACH configuration index: prach-ConfigurationIndex configured in RRC;

[0103] Preamble format: preamble format B4 is used;

[0104] nf mod x = y: The PRACH configuration period (PRACH configuration period) is 2 frames (x = 2), and the RO is on the odd frame (y = 1) in 2 frames.

[0105] Subframe number: The RO is on subframes 2, 3, 4, 7, 8, and 9 within the odd frame.

[0106] Starting Symbol: The starting symbol of the RO within the PRACH slot is 0.

[0107] Number of PRACH slots within a subframe: The number of PRACH slots within a subframe is 1 (the length of the subframe is 1 ms, and the corresponding SCS is 15 KHz, at this time, the length of the PRACH slot is 1 ms, and the SCS is 15 KHz).

[0108] Number of time-domain PRACH occasions within a PRACH slot: In the time domain, one PRACH slot contains 1 RO.

[0109] PRACH duration: The length of one RO symbol: 12 symbols.

[0110] The frequency domain where the RO is located is determined according to the following parameters:

[0111] msg1-FDM ENUMERATED {one, two, four, eight};

[0112] msg1-FrequencyStart INTEGER (0..maxNrofPhysicalResourceBlocks-1);

[0113] msg1-FDM: In the frequency domain, the number of FDM ROs in one PRACH slot.

[0114] msg1-FrequencyStart: the starting RB of the first RO in frequency domain of FDM, which is the offset of the first RB relative to the UL BWP;

[0115] Number of RBs occupied by one RO: determined according to the sequence length of PRACH signal and SCS.

[0116] The sequence length of PRACH signal can be determined according to prach-ConfigurationIndex to determine Preamble format, and the sequence length of PRACH signal is determined according to the sequence length of Preamble format agreed by the protocol.

[0117] The SCS of PRACH signal can be determined according to the number of slots of RO included in a subframe indicated by prach-ConfigurationIndex.

[0118] Table 1

[0119] In SBFD symbols, the UE can send uplink signals in UL SB, so the RO can be configured in SBFD symbols, compared with configuring RO only in UL or F symbols, the number of ROs can be increased. SBFD-aware UE (UE that can identify SBFD symbol configuration) can configure RO in SBFD symbols for random access, reduce access delay, and also reduce the collision probability of PRACH signals of different UEs in CBRA.

[0120] In consideration of the available frequency domain range of UL in SBFD symbols and non-SBFD symbols, in order to enable the use of RO in SBFD symbols in RACH resource configuration, it is necessary to ensure that the RO in SBFD symbols is within the UL sub-band. The non-SBFD symbol can be any symbol other than the SBFD symbol. For example, the non-SBFD symbol can include an UL symbol and / or a DL symbol. The UL symbol can be dedicated to UL transmission. The DL symbol can be dedicated to DL transmission. FIG. 1D shows the configuration of RO in one PRACH configuration period. For example, the ROs are in subframes #2, 3, 4, 7, 8, and 9. In the time domain, one PRACH slot contains one RO, and the symbol range of the first RO in one subframe is OFDM symbol OS#0-11. In the frequency domain, one PRACH slot contains two ROs. For SBFD-aware UEs, there are eight additional ROs and four original ROs. For non-SBFD-aware UEs, there are four original ROs. The eight additional ROs are RO#0-3 and RO#6-9, respectively. The four original ROs are RO#4-5 and RO#10-11, respectively.

[0121] When enabling SBFD-aware UEs to use ROs in SBFD symbols, the following methods can be used:

[0122] The first configuration can be used to configure the first RACH resource. The first RACH resource can be used by non-SBFD-aware UEs and SBFD-aware UEs. The SBFD-aware UEs can use one or more of the first type of RO, the second type of RO, and the third type of RO in the first RACH resource. RACH Config#1 is used to configure the first RACH resource. As shown in FIG. 1E, the first RACH resource includes RO#1, RO#2, RO#3, and RO#4. It can be seen that the first RACH resource can be configured with ROs in the SBFD time unit of the F time unit and the DL time unit. As shown in FIG. 1E, the ROs available to non-SBFD-aware UEs include RO#3 and RO#4. The ROs available to SBFD-aware UEs include RO#1, RO#2, RO#3, and RO#4.

[0123] The second configuration can be used to configure the second RACH resource and the third RACH resource. The second RACH resource and the third RACH resource can be used by non-SBFD aware UE and SBFD aware UE respectively. The SBFD aware UE can use one or more of the first type RO, the second type RO, and the third type RO in the third RACH resource. Optionally, the SBFD aware UE can use one or more of the first type RO and the second type RO in the second RACH resource. The RACH Config#2 is used to configure the second RACH resource. As shown in FIG. 1F, the second RACH resource includes RO#4 and RO#5. It can be seen that the second RACH resource can configure ROs in the SBFD time unit of the F time unit. The RACH Config#3 is used to configure the third RACH resource. As shown in FIG. 1F, the third RACH resource includes RO#1, RO#2, and RO#3. As shown in FIG. 1F, the RO#4 and the RO#5 can be used by the SBFD aware UE and the non-SBFD aware UE. The RO#1, the RO#2, and the RO#3 can be used by the SBFD aware UE.

[0124] The third configuration can be used to configure the first RACH resource. The first RACH resource can be used by the non-SBFD aware UE and the SBFD aware UE. The third RACH resource can be used by the SBFD aware UE.

[0125] The SBFD aware UE supports the first capability and the second capability. The SBFD aware UE can use one or more of the first type RO, the second type RO, and the third type RO in the first RACH resource. The SBFD aware UE can use one or more of the first type RO, the second type RO, and the third type RO in the third RACH resource.

[0126] The fourth configuration can be used to configure the second RACH resource. The second RACH resource can be used by the non-SBFD aware UE.

[0127] Optionally, the SBFD aware UE can use one or more of the first type RO and / or the second type RO in the second RACH resource.

[0128] The first type RO, the second type RO, and the third type RO are defined as follows:

[0129] The first type RO includes the ROs of non-SBFD symbols, and the first type RO does not include the ROs of SBFD symbols.

[0130] The second type of RO includes the ROs of the first type of SBFD symbol and the second type of SBFD symbol.

[0131] The third type of RO includes the ROs of the second type of SBFD symbol.

[0132] In some embodiments, the first type of SBFD symbol can include: the ROs of SBFD symbols on flexible (F) time units and / or SBFD symbols configured on any time units in the absence of TDD-UL-DL-ConfigCommon configuration. For example, SBFD symbols configured on any time slots or subframes in the absence of TDD-UL-DL-ConfigCommon configuration. At this time, such time slots or subframes are neither UL time units nor DL time units.

[0133] The second type of SBFD symbol includes SBFD symbols configured on downlink (DL) time units.

[0134] FIG. 1E shows a schematic diagram of a first configuration. The SBFD aware UE can use all ROs in the first configuration, and the non SBFD aware UE can use the ROs configured on F time units and uplink (UL) in the first configuration.

[0135] FIG. 1F shows a schematic diagram of a second configuration. The SBFD aware UE can use all ROs in the second configuration, and the non SBFD aware UE can use the ROs configured on F time units and uplink (UL) in the RACH Config#2.

[0136] In the presence of the following problems: the UE can support at least one of the first configuration, the second configuration and the third configuration, the network can configure at least one of the first configuration, the second configuration and the third configuration, and the RACH configuration configured by the network side is different from the RACH configuration supported by the UE, it is necessary to determine the RO resources that can be used by the UE.

[0137] FIG. 2A is an interaction schematic diagram of a RO determination method according to an exemplary embodiment. As shown in FIG. 2A, the embodiment of the present disclosure relates to a RO determination method for the communication system 100, and the method comprises:

[0138] S2101: The network device sends a RACH resource configuration to the UE.

[0139] In some embodiments, the network device can be an access network device, which can include but is not limited to eNB and / or gNB, etc.

[0140] In some embodiments, RACH resource configuration is used to configure RO. In some embodiments, RACH resource configuration is in SIB.

[0141] In some embodiments, the network device sends a Radio Resource Control (RRC) message, a Media Access Control (MAC) layer message, or a physical layer message to the UE. The RRC message, MAC layer message, or physical layer message may include the aforementioned RACH resource configuration.

[0142] In some embodiments, RACH resource configuration can be used by the UE to determine the resource locations of one or more Resource Entities (ROs). Exemplarily, the RACH resource configuration may include, but is not limited to, at least one of the following:

[0143] The PRACH configuration index can be used to indicate the preamble format, configuration period, and subframe number.

[0144] Number of PRACH slots within a subframe; one or more of the lengths of the ROs; Msg1-FDM, used to indicate the number of ROs in frequency division multiplexing. Msg1-FDM can be an enumerated parameter, with values ​​of 1, 2, 4, or 8.

[0145] The above are just examples of RACH resource configuration; RACH resource configuration is not limited to the examples above.

[0146] The network device sends the RACH resource configuration, and the UE receives the RACH resource configuration accordingly.

[0147] In some embodiments, the network device sends RACH resources to various types of UEs. For example, the network device sends RACH resource configurations to non-SBFD aware UEs and / or SBFD aware UEs.

[0148] In some embodiments, the RACH resource configuration is used for at least one of a non-SBFD aware UE and an SBFD aware UE.

[0149] RACH resource configuration includes at least one of the following:

[0150] The time-domain configuration information of RACH resources is used to determine the time-domain location of RO;

[0151] Frequency domain configuration information of the RACH resource, used to determine the frequency domain location of the RO.

[0152] In some embodiments, the ROs can be classified into SBFD time unit ROs and non-SBFD time unit ROs according to whether the ROs are configured on SBFD time units. The SBFD time unit can include, but is not limited to, an SBFD symbol, an SBFD mini-slot, or an SBFD slot. The SBFD mini-slot contains a smaller number of symbols than the SBFD slot.

[0153] In some embodiments, the ROs include at least one of the following:

[0154] The first type of RO is located in a time unit that is a non-sub-band duplex (SBFD) time unit.

[0155] The second type of RO is located in a time unit that is at least partially an SBFD time unit within a flexible (F) time unit, and the time unit in which the second type of RO is located is not an SBFD time unit within a downlink (DL) time unit.

[0156] The third type of RO is located in a time unit that is at least partially an SBFD time unit within a DL time unit.

[0157] In some embodiments, the time unit in which the first type of RO is located can be an UL time unit or a non-SBFD time unit of a flexible time unit.

[0158] In some embodiments, the time unit in which the second type of RO is located is entirely an SBFD time unit of an F time unit, and / or the time unit in which the second type of RO is located is partially an SBFD time unit of an F time unit and partially located on an UL time unit.

[0159] In some embodiments, the time unit in which the third type of RO is located can be partially an SBFD time unit of a DL time unit, or the time unit in which the third type of RO is located is entirely an SBFD time unit of a DL time unit.

[0160] In some embodiments, the flexible time units comprise at least one of the following: flexible time units configured by TDD-UL-DL-ConfigCommon; time units not configured by TDD-UL-DL-ConfigCommon; time units not configured by time division multiplexing-uplink-downlink dedicated, DD-UL-DL-ConfigDedicated. In some embodiments, in case that the network device does not send TDD-UL-DL-ConfigCommon and / or DD-UL-DL-ConfigDedicated information element (IE), the time units available to the UE are not configured by TDD-UL-DL-ConfigCommon IE and / or DD-UL-DL-ConfigDedicated IE.

[0161] As shown in FIG. 2B and FIG. 2C, RO#1 is a first type of RO; RO#2 and RO#3 are a second type of RO; RO#4, RO#5 and RO#6 are a third type of RO.

[0162] In some embodiments, the RACH resource configuration can be any information for configuring RACH resources. Exemplarily, the RACH resource configuration provided by the network device can comprise one or more of the following. For example, the RACH resource configuration can comprise at least one of the following: a first configuration for configuring a first RACH resource; a second configuration for configuring a second RACH resource and a third RACH resource; a third configuration for configuring the first RACH resource and the third RACH resource; a fourth configuration for configuring the second RACH resource.

[0163] In some embodiments, the first RACH resource comprises at least one of the first type of RO, the second type of RO and the third type of RO.

[0164] In some embodiments, the second RACH resource comprises at least one of the first type of RO and the second type of RO.

[0165] In some embodiments, the third RACH resource comprises at least one of the second type of RO and the third type of RO, or the third RACH resource comprises at least one of the first type of RO, the second type of RO and the third type of RO.

[0166] Comparing the three RACH resource configurations, it can be seen that the type of RO associated with the second RACH resource is less than the type of RO associated with the first RACH resource. The RO associated with the third RACH resource has two types, one of which is the same as the first RACH resource, and the other is different from the first RACH resource.

[0167] In some embodiments, the second RACH resource can be a subset of the first RACH resource. For example, the second RACH resource can include part and / or all of the ROs in the first RACH resource. For example, the second RACH resource can include part or all of the specific ROs in the first RACH resource. The specific ROs can include the first type of RO and / or the second type of RO.

[0168] In some embodiments, the capability of the UE includes at least one of the first capability and the second capability. For example, the definition of the first capability and the second capability can include multiple options, for example, the following three options:

[0169] Option 1: The first capability includes the capability of identifying the first RACH resource and the second RACH resource, and the second capability includes the capability of identifying the second RACH resource and the third RACH resource.

[0170] Option 2: The first capability includes the capability of identifying the first RACH resource, the second RACH resource and the third RACH resource, and the second capability includes the capability of identifying the second RACH resource and the third RACH resource.

[0171] Option 3: The first capability includes the capability of identifying the first RACH resource and the second RACH resource, and the second capability includes the capability of identifying the first RACH resource, the second RACH resource and the third RACH resource.

[0172] Of course, there is also a possibility that the UE has only one capability, and the UE's capability supports the identification of the first RACH resource, the second RACH resource and the third RACH resource. The UE can identify the corresponding type of RACH resource, and can identify that a certain time-frequency domain resource is configured as a RACH resource, or will not identify the corresponding RACH resource as an abnormal configuration, etc.

[0173] Since the RACH resource configuration includes at least four types, the RACH resource currently sent by the network device to the UE can be one or more of the first configuration, the second configuration, the third configuration and the fourth configuration.

[0174] In some embodiments, the network device sends the RACH resource configuration, and the UE receives the corresponding RACH resource configuration.

[0175] By configuring the ROs in the SBFD time units, the RO capacity can be increased, the competition degree of the RO initiated random access between UEs can be reduced, and by configuring the ROs on the SBFD time units of the DL time units and / or the F time units, the UE can also initiate random access on these ROs, without waiting for the RO on the UL time unit to initiate random access, thereby reducing the delay of random access.

[0176] S2102: The network device and the UE determine ROs that the UE can use according to the capability of the UE and the RACH resource configuration.

[0177] In some embodiments, the determining of the ROs that the UE can use according to the RACH resource configuration and the capability of the UE includes at least one of the following:

[0178] The RACH resource configuration information includes the first configuration and the UE supports the first capability, and the determining of the UE to be able to use the first type of RO, the second type of RO and the third type of RO included in the first configuration includes the following:

[0179] The RACH resource configuration information includes the first configuration and the UE supports the second capability, and the determining of the UE to be able to use the first type of RO and the second type of RO included in the first configuration includes the following:

[0180] The RACH resource configuration information includes the first configuration and the UE supports the second capability, and the determining of the UE to be able to use the third type of RO included in the first configuration includes the following:

[0181] The RACH resource configuration information includes the first configuration and the UE supports the second capability, and the determining of the UE to be able to use the second type of RO and the third type of RO included in the first configuration includes the following:

[0182] The RACH resource configuration information includes the first configuration and the UE supports the second capability, and the determining of the UE to be able to use the first type of RO, the second type of RO and the third type of RO included in the first configuration includes the following:

[0183] The RACH resource configuration information includes the first configuration and the UE supports the first capability and the second capability, and the determining of the UE to be able to use the first type of RO, the second type of RO and the third type of RO included in the first configuration includes the following.

[0184] In some embodiments, no matter which one of the options 1 to 3 is used in the definition of the first capability, the UE supporting the first capability is able to identify the first RACH resource and the second RACH resource, and thus, in the case that the UE supports the first capability, the UE can use one or more of the first type of ROs, the second type of ROs and the third type of ROs of the first RACH resource corresponding to the first configuration. At this time, the UE can use any one of the ROs for random access, which has the characteristics of wide range of ROs available, large number of ROs available, large random capacity and fast random response rate.

[0185] In some embodiments, no matter which one of the options 1 to 3 is used in the definition of the second capability, in the case that the UE supports the second capability, the UE is able to identify at least the second RACH resource and the third RACH resource. In some scenarios, in the case that the UE supports the second capability, the UE has an extended identification capability in addition to a basic identification capability, and the basic identification capability is to identify the second RACH resource and the third RACH resource. The extended identification capability is to identify the third capability. In this case, the UE is able to use the ROs contained in the second RACH resource and / or the third RACH resource. In a specific scenario, the UE is also able to use the ROs in the first RACH resource.

[0186] Therefore, in some embodiments, in the case that the definition of the second capability uses the option 3, the UE supporting the second capability is able to identify the first RACH resource, and thus can use the first RACH resource. Exemplarily, the UE can use one of the indications of the first type of ROs, the second type of ROs and the third type of ROs in the first RACH resource.

[0187] In some embodiments, the determining of the ROs available to the UE according to the RACH resource configuration and the capability of the UE comprises at least one of:

[0188] The RACH resource configuration information comprises the second configuration and the UE supports the first capability, and the determining of the ROs available to the UE comprises the first type of ROs and the second type of ROs included in the second RACH resource;

[0189] The RACH resource configuration information comprises the second configuration and the UE supports the first capability, and the determining of the ROs available to the UE comprises the second type of ROs and the third type of ROs included in the third RACH resource;

[0190] The RACH resource configuration information comprises the second configuration and the UE supports the first capability, and the determining of the ROs available to the UE comprises the first type of ROs, the second type of ROs and the third type of ROs included in the third RACH resource;

[0191] In some embodiments, if the definition of the first capability and the second capability adopts Option 3, in the case that the UE supports the first capability, the UE can use any one of the first type of RO included in the first RACH resource, the second type of RO included in the second RACH resource, and the third type of RO included in the third RACH resource. In the case that the UE supports the second capability, the UE can use any one of the second type of RO included in the second RACH resource and the third type of RO included in the third RACH resource.

[0192] In some embodiments, if the definition of the first capability and the second capability adopts Option 3, in the case that the UE supports the first capability, the UE can use any one of the first type of RO included in the first RACH resource, the second type of RO included in the second RACH resource, and the third type of RO included in the third RACH resource. In the case that the UE supports the second capability, the UE can use any one of the second type of RO included in the second RACH resource and the third type of RO included in the third RACH resource.

[0193] In some embodiments, if the definition of the first capability and the second capability adopts Option 3, in the case that the UE supports the first capability, the UE can use any one of the first type of RO included in the first RACH resource, the second type of RO included in the second RACH resource, and the third type of RO included in the third RACH resource. In the case that the UE supports the second capability, the UE can use any one of the second type of RO included in the second RACH resource and the third type of RO included in the third RACH resource.

[0194] In some embodiments, if the definition of the first capability and the second capability adopts Option 3, in the case that the UE supports the first capability, the UE can use any one of the first type of RO included in the first RACH resource, the second type of RO included in the second RACH resource, and the third type of RO included in the third RACH resource.

In some embodiments, the UE supports the first capability and the second capability, and the final enabled capability is the capability reported by the UE to the network device or the capability indicated by the network device to the UE.

[0308] Option 1-2: In the case of the second configuration configured on the network side, the UE can use at least one of the first type of RO and the second type of RO in RACH Config#2 and / or at least one of the first type of RO, the second type of RO and the third type of RO in RACH Config#3. RACH Config#2 represents the second RACH resource. RACH Config#3 represents the third RACH resource.

[0309] Exemplarily, the RACH resource that the UE can use can be as follows:

[0310] Option 1-2-1: The UE can use the first type of RO and the second type of RO in RACH Config#2;

[0311] Option 1-2-2: The UE can use the second type of RO and the third type of RO in RACH Config#3;

[0315] When the UE supports the first capability and the second capability, the UE can use at least one of Option 1-2-4 to Option 1-2-5.

[0316] When the UE supports the first capability, the UE can use at least one of Option 1-2-1 to Option 1-2-5.

[0317] When the UE supports the second capability, the UE can use at least one of Option 1-2-4 and Option 1-2-5.

[0318] Option 1-3: In the case that the network side configuration is the third configuration, the UE can use at least one of the first type of RO, the second type of RO, the third type of RO in RACH Config#1 and / or at least one of the first type of RO, the second type of RO, the third type of RO in RACH Config#3. RACH Config#1 represents the first RACH resource. RACH Config#3 represents the third RACH resource.

[0319] Exemplarily, the RACH resource that the UE can use is as follows:

[0320] Option 1-3-1: The UE can use the first type of RO and the second type of RO in RACH Config#1;

[0321] Option 1-3-2: The UE can use the third type of RO in RACH Config#1;

[0330] The UE can support at least one of the options 1-3-1 to 1-3-10 when the UE supports the first capability or the second capability.

[0331] The UE can support at least one of the options 1-3-9 and 1-3-10 when the UE supports the first capability and the second capability.

[0332] Option 1-4: In the case that the network side configuration is the fourth configuration, the UE can use at least one of the first type of RO and the second type of RO in RACH Config#2. RACH Config#2 represents the second RACH resource.

[0333] Exemplarily, the RACH resource that the UE can use can include:

[0334] Option 1-4-1: The UE can use the first type of RO and the second type of RO in RACH Config#2.

[0335] The UE can support the option 1-4-1 when the UE supports the first capability and / or the second capability.

[0336] In the options 1-1 to 1-4, after determining the RO that the UE can use, the UE can determine the actually used RO according to the requirement, the actually used RO of the UE is part or all of the RO that can be used.

[0337] In some embodiments, the second RACH resource can be a resource subset of the first RACH resource. Exemplarily, the second RACH resource can include part and / or all of the RO in the first RACH resource. For example, the second RACH resource can include part or all of the specific RO in the first RACH resource. The specific RO can include the first type of RO and / or the second type of RO.

[0338] In some embodiments, the UE does not support the first capability and the second capability, in which case the UE can only identify the second RACH resource, the UE can use the first type RO and / or the second type RO of the second RACH resource. In case the RACH resource configuration includes the first configuration or the third configuration, the UE can use the first type RO and / or the second type RO of the first RACH resource; in case the RACH resource configuration includes the second configuration or the fourth configuration, the UE can use the first type RO and / or the second type RO of the second RACH resource.

[0339] In Option 1, the first type RO includes ROs of non-SBFD symbols, and the first type RO does not include ROs of SBFD symbols. The second type RO includes ROs of the first type SBFD symbols, and the second type RO does not include ROs of the second type SBFD symbols. The third type RO includes ROs of the second type SBFD symbols. The non-SBFD symbol is one of non-SBFD time units.

[0340] In some embodiments, the first type SBFD symbol can include ROs of SBFD symbols on flexible (F) time units, and / or configured as SBFD symbols without TDD-UL-DL-ConfigCommon configuration. The second type SBFD symbol includes SBFD symbols configured on downlink (DL) time units.

[0341] The UE can determine valid ROs in the first type RO, the second type RO, and / or the third type RO. The UE will initiate random access on the valid ROs.

[0342] In some embodiments, the protocol agrees / higher layer configures one valid RO in the second type RO and / or the third type RO can occupy both SBFD symbols and non-SBFD symbols. Exemplarily, the higher layer configuration can be RACH resource configuration using RRC message or MAC layer message.

[0343] In some embodiments, the capability of the UE can also be divided into a third capability and a fourth capability according to whether the UE supports sending a random access request according to a specific type RO. The specific type RO can be a RO occupying both SBFD time units and non-SBFD time units.

[0344] In some embodiments, the UE has the third capability, which means the UE supports sending a random access request on the specific type of RO. In some embodiments, the UE has the fourth capability, which means the UE does not support sending a random access request on the specific type of RO. For example, the UE has the third capability, which means the UE supports transmitting a PRACH signal on an RO that spans both SBFD symbols and non-SBFD symbols. The PRACH signal is one type of random access request. In some embodiments, the UE has the fourth capability, which means the UE does not support transmitting a PRACH signal on an RO that spans both SBFD symbols and non-SBFD symbols.

[0345] In some embodiments, the UE has a default capability, which can be the third capability or the fourth capability. In some embodiments, the UE supports both the third capability and the fourth capability, and the enabled capability is the capability reported by the UE to the network device or the capability indicated by the network device to the UE.

[0346] In some embodiments, the UE does not report the default capability to the network device. For example, the third capability or the fourth capability is the default capability. Base station side: the base station determines the used RACH resource by the following method.

[0347] In some embodiments, the UE supports the third capability, and the UE can use the specific type of RO to send a random access request when the protocol agreement / high layer configuration indicates that one of the valid ROs in the second type of RO and the third type of RO can occupy both SBFD symbols and non-SBFD symbols.

[0348] In some embodiments, the UE supports the third capability, and the UE cannot use the specific type of RO to send a random access request when the protocol agreement / high layer configuration indicates that one of the valid ROs in the second type of RO and the third type of RO cannot occupy both SBFD symbols and non-SBFD symbols.

[0349] The network device (e.g., the base station) can provide one or more of the first configuration, the second configuration, and the third configuration to the UE. The base station can also determine the RACH resource that can be used by the UE according to the RACH resource configuration and the capability of the UE. For example, the base station can determine one or more types of ROs (i.e., one or more) included in the RACH resource that can be used by the UE according to the RACH resource configuration and the capability of the UE.

[0350] The RACH resource that can be used by the UE is determined according to the first configuration, the second configuration, the third configuration, the fourth configuration, and the capability of the UE. The determination method is the same as that on the UE side, which will not be described here.

[0351] UE side: SBFD aware UE UE determines the used RACH resource by the following method. First configuration, which can be used to configure the first RACH resource, the first RACH resource contains at least one of the first type RO, the second type RO, the third type RO. Second configuration, which can be used to configure the second RACH resource and the third RACH resource, the second RACH resource contains at least one of the first type RO and the second type RO, and the third RACH resource contains at least one of the first type RO, the second type RO and the third type RO. Third configuration, which can be used to configure the first RACH resource and the third RACH resource. Fourth configuration, which can be used to configure the second RACH resource.

[0352] Option 1: According to the first configuration, the second configuration, the third configuration, the fourth configuration and the capability of the UE, determine the RACH resource that the UE can use.

[0353] Option 1-1: The first configuration configured by the base station, the RACH resource that the UE can use.

[0360] When the UE supports the first capability, option 1-1-4 can be used, and when the UE supports the second capability, one of options 1-1-1~1-1-4 can be used.

[0361] In Option 1-1, one example is as follows, RACH Config#1 contains RO#1-1, 1-2, 1-3, 1-4 in time slot#1, 2, 3, 4. Among them, RO#1-4 is the first type of RO, RO#1-3 is the second type of RO, RO#1-1, #1-2 is the third type of RO. The non-SBFD aware UE can identify RO#1-3, #1-4 in RACH Config#1.

[0362] When the SBFD aware UE supports the first capability,

[0363] The SBFD aware UE can identify the first type of RO, the second type of RO and the third type of RO in RACH Config#1, and can use Option 1-1-4. Of course, the SBFD aware UE can also use Option 1-1-1, 1-1-2, 1-1-3.

[0364] When the SBFD aware UE supports the second capability, if the SBFD aware UE can identify the first type of RO and the second type of RO in RACH Config#1, Option 1-1-1 can be supported.

[0365] If the SBFD aware UE can identify the first type of RO, the second type of RO and the third type of RO in RACH Config#1, Option 1-1-4 can be used. Of course, the SBFD aware UE can also choose to use Option 1-1-1, 1-1-2, 1-1-3.

[0373] Option 1-2-5: The UE can use the first type of RO and the second type of RO in RACH Config#2 and the first type of RO, the second type of RO and the third type of RO in RACH Config#3.

[0374] When the UE supports the first capability and / or the second capability, at least one of options 1-2-1 to 1-2-5 can be used.

[0375] When the UE supports the first capability, at least one of options 1-2-1 to 1-2-5 can be used, and when the UE supports the second capability, at least one of options 1-2-4 and 1-2-5 can be used.

The non-SBFD aware UE can identify RO#2-1, #2-2 in RACH Config#2. RACH Config#3 contains RO#3-1, 3-2, 3-3 in slots #1, 2, 3. Among them, RO#3-3 is the second type of RO, and RO#3-1, #3-2 is the third type of RO. The non-SBFD aware UE cannot identify the RO in RACH Config#3.

[0378] If the SBFD aware UE can identify the second type of RO and the third type of RO in RACH Config#3, option 1-2-2 can be used.

[0379] If the SBFD aware UE can identify the first type of RO and the second type of RO in RACH Config#2 and the second type of RO and the third type of RO in RACH Config#3, option 1-2-4 can be used. Of course, the SBFD aware UE can also choose to use options 1-2-1 and 1-2-2.

Of course, the SBFD aware UE can also choose to use option 1-2-1, 1-2-2.

[0381] Figure 5B shows the RACH resource configuration provided by the base station for the UE to use the RO when using option 1-2-1 and option 1-2-2 in the case of the second configuration.

[0399] When the UE supports the first capability or the second capability, at least one of the options 1-3-1 to 1-3-10 can be used.

[0400] When the UE supports the first capability and the second capability, at least one of the options 1-3-9 and 1-3-10 can be used.

[0401] In Option 1-3, one example is as follows, RACH Config#1 contains RO#1-1, 1-2, 1-3, 1-4 in time slot#1, 2, 3, 4. Among them, RO#1-4 is the first type RO, RO#1-3 is the second type RO, RO#1-1, #1-2 is the third type RO. The non-SBFD aware UE can identify RO#1-3, #1-4 in RACH Config#1.

[0402] When the SBFD aware UE supports the first capability, the SBFD aware UE can identify the first type RO, the second type RO and the third type RO in RACH Config#1, the UE can use Option 1-3-4. Of course, the SBFD aware UE also supports Option 1-3-1, 1-3-2, 1-3-3.

[0403] If the SBFD aware UE can identify the second type RO and the third type RO in RACH Config#3, the SBFD aware UE option supports 1-3-5.

[0404] If the SBFD aware UE can identify the first type RO, the second type RO and the third type RO in RACH Config#1, the second type RO and the third type RO in RACH Config#3, it can use Option 1-3-9. Of course, the SBFD aware UE can also choose to use Option 1-3-1 to 1-3-5, 1-3-7.

[0405] When the SBFD aware UE supports the second capability, the SBFD aware UE can identify the first type RO, the second type RO in RACH Config#1, the second type RO and the third type RO in RACH Config#3, it can use Option 1-3-7. Of course, the SBFD aware UE can also choose to use Option 1-3-1, 1-3-5.

[0406] If the SBFD aware UE can identify the first type RO, the second type RO and the third type RO in RACH Config#1, the second type RO and the third type RO in RACH Config#3, it can use Option 1-3-9. Of course, the SBFD aware UE can also choose to use Option 1-3-1 to 1-3-5, 1-3-7.

[0407] Figure 5D shows the ROs that the UE can use when using Option 1-3-4 and Option 1-3-5 when the RACH resource configuration is the fourth configuration.

[0408] In Option 1-3, one example is as follows, RACH Config#1 contains RO#1-1, 1-2, 1-3, 1-4 in time slot #1, 2, 3, 4. Among them, RO#1-4 is the first type RO, RO#1-3 is the second type RO, RO#1-1, #1-2 is the third type RO. The non-SBFD aware UE can identify RO#1-3, #1-4 in RACH Config#1.

The non-SBFD aware UE cannot identify the RO in RACH Config#3.

[0409] When the SBFD aware UE supports the first capability, the SBFD aware UE can identify the first type RO, the second type RO and the third type RO in RACH Config#1, it can use Option 1-3-4. Of course, the SBFD aware UE can also choose to use Option 1-3-1, 1-3-2, 1-3-3.

[0410] If the SBFD aware UE can identify the 1st type RO, 2nd type RO and 3rd type RO in RACH Config#3, Option 1-3-6 can be used.

[0411] If the SBFD aware UE can identify the 1st type RO, 2nd type RO and 3rd type RO in RACH Config#1, the 1st type RO, 2nd type RO and 3rd type RO in RACH Config#3, Option 1-3-10 can be used. Of course, the SBFD aware UE can also choose to use Option 1-3-1 to 1-3-9.

[0412] If the SBFD aware UE supports the 2nd capability, the SBFD aware UE can identify the 1st type RO, 2nd type RO in RACH Config#1, the 1st type RO, 2nd type RO and 3rd type RO in RACH Config#3, Option 1-3-8 can be used. Of course, the SBFD aware UE can also choose to use Option 1-3-1, 1-3-5 to 1-3-7.

[0413] If the SBFD aware UE can identify the 1st type RO, 2nd type RO and 3rd type RO in RACH Config#1, the 1st type RO, 2nd type RO and 3rd type RO in RACH Config#3, Option 1-3-10 can be used. Of course, the SBFD aware UE can also choose to use Option 1-3-1 to 1-3-9.

[0414] Figure 5E shows the ROs available to the UE when using Option 1-3-4 and 1-3-6 in the case of the first configuration.

[0415] Option 1-4: The fourth configuration is configured, and the RACH resources available to the UE.

[0416] The UE can use at least one of the 1st type RO and 2nd type RO in RACH Config#2.

[0417] Option 1-4-1: The UE can use the 1st type RO and 2nd type RO in RACH Config#2.

[0418] When the UE supports the 1st capability and / or the 2nd capability, Option 1-4-1 can be used.

[0419] In the above options, the 1st type RO: the RO containing non-SBFD symbol, the RO not containing SBFD symbol, and

[0420] The second type of RO: the RO containing SBFD (legacy F) and not containing SBFD (legacy DL).

[0421] SBFD (legacy F): TDD-UL-DL-ConfigCommon is configured as F or no TDD-UL-DL-ConfigCommon configuration, and is configured as SBFD symbol.

[0422] SBFD (legacy DL): TDD-UL-DL-ConfigCommon is configured as DL, and is configured as SBFD symbol.

[0423] The third type of RO: the RO containing SBFD (legacy DL).

[0424] The first type of RO, the second type of RO, and the third type of RO used by the UE are valid ROs.

[0425] The protocol agrees or higher layer configures that one of the second type of RO and the third type of RO can contain SBFD symbol and non-SBFD symbol at the same time.

[0426] The UE reports the third capability or the fourth capability, the third capability supports transmitting PRACH signal when one RO contains SBFD symbol and non-SBFD symbol at the same time, and the fourth capability does not support transmitting PRACH signal when one RO contains SBFD symbol and non-SBFD symbol at the same time.

[0427] The default capability of the UE does not need to be reported. The third capability or the fourth capability is the default capability.
