The network element can be virtual or physical. The core network may, for example, include at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

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

[0142] 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, allow 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 as 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 slot that includes at least one SBFD symbol in the multiple symbols included in the slot can be referred to as an SBFD slot. As shown in FIG. 1B, slot #0 is a DL slot, including 14 DL symbols, and slots #1-3 are SBFD slots, each including 14 SBFD symbols. Slot #4 is a UL 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.

[0143] 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.

[0144] There can also be a guard band (GB) between the DL sub-band and the UL sub-band to reduce the interference between the DL signal in the DL sub-band and the UL signal in the UL sub-band by frequency domain isolation. As shown in FIG. 1C, a DL slot is divided into a DL sub-band (SB), an UL SB, and a DL SB. The UL SB can be configured with an RO.

[0145] In a SBFD symbol, the frequency domain range available for UL transmission can not be continuous, including the following two cases: the GB and the DL sub-band are not available for UL transmission, and the UL sub-band is available for UL transmission; the DL sub-band is not available for UL transmission, and the UL sub-band and the GB are available for UL transmission.

[0146] The frequency domain range available for UL transmission in a SBFD symbol can be referred to as the UL frequency domain range, and the frequency domain range not available for UL transmission in a SBFD symbol can be referred to as outside the UL frequency domain range. As known from the above, the UL frequency domain range of a non-SBFD symbol and the UL frequency domain range of a SBFD symbol are different. The UL frequency domain range is the UL frequency domain range on a CC. In a SBFD symbol, the UL frequency domain range on a BWP refers to the frequency domain range overlapping the UL frequency domain range on the CC. Unless otherwise specified, the UL frequency domain range hereinafter refers to the UL frequency domain range on a BWP.

[0147] 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, a 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 a PRACH signal in the valid RO to perform random access. Random access includes CBRA (Contention-Based Random Access) and CFRA (Contention-Free Random Access), where there are multiple UE using the same preamble sequence (preamble) in CBRA, i.e., the PRACH signals of 2 UEs collide, which will cause random access failure.

[0148] As shown in FIG. 1C, the DL frequency band is divided into DL sub-band (SB), UL SB and DL SB. The UL SB can be configured with RO. That is, the RO can be configured on the SBFD symbol to increase the number of ROs within one subframe or one radio frame. The SBFD-aware UE (UE that can identify the SBFD symbol configuration) can configure the RO on the SBFD symbol to reduce the access delay and also reduce the PRACH signal collision probability of different UEs in CBRA.

[0149] The parameter prach-ConfigurationIndex is configured in RRC, and the time domain configuration of the RO is determined in combination with the PRACH Configuration Index column in Table 1. An example can be as shown in FIG. 1D, in which there is no RO on the SBFD symbol.

[0150] In some embodiments, the time domain location of the RO can be determined according to the index prach-ConfigurationIndex and as shown in Table 1.

[0151] prach-ConfigurationIndex INTEGER(0..255);

[0152] PRACH configuration index: prach-ConfigurationIndex configured in RRC;

[0153] Preamble format: preamble format B4 is used;

[0154] nf mod x=y: the configuration period of the RO (PRACH configuration period) is 2 frames (x=2), and the RO is on the odd frame (y=1) in the 2 frames.

[0155] Subframe number: the RO is on subframes 2, 3, 4, 7, 8, 9 in the odd frame.

[0156] Starting Symbol: the starting symbol of the RO in the PRACH slot is 0.

[0157] Number of PRACH slots within a subframe: the number of PRACH slots in one 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).

[0158] Number of time-domain PRACH occasions within a PRACH slot: 1 RO in time domain within a PRACH slot.

[0159] PRACH duration: 12 symbols.

[0160] The frequency domain where the RO is located is determined according to the following parameters:

[0161] msg1-FDM ENUMERATED {one, two, four, eight};

[0162] msg1-FrequencyStart INTEGER (0..maxNrofPhysicalResourceBlocks-1);

[0163] msg1-FDM: The number of FDMed ROs in a PRACH slot in frequency domain.

[0164] msg1-FrequencyStart: The starting RB of the first RO in the FDMed ROs in frequency domain, which is the frequency offset relative to the first RB of the UL BWP.

[0165] The number of RBs occupied by one RO is determined according to the sequence length of the PRACH signal and the SCS.

[0166] The sequence length of the PRACH signal can be determined according to the Preamble format determined by prach-ConfigurationIndex, and the sequence length of the Preamble format according to the protocol.

[0167] The SCS of the PRACH signal can be determined according to the number of PRACH slots within a subframe indicated by prach-ConfigurationIndex.

[0168] Table 1

[0169] In SBFD symbols, a UE can transmit uplink signals on UL SB, thus the network device can configure ROs in SBFD symbols, which can increase the number of ROs compared to configuring ROs in UL or F symbols only. A SBFD-aware UE (a UE that can identify SBFD symbol configuration) can configure ROs in SBFD symbols for random access, which can reduce access latency and also reduce the probability of PRACH signal collision among different UEs in CBRA.

[0170] When configuring RACH resources for SBFD-aware UEs, the following problems exist:

[0171] In the table of frequency range 1 (FR1) and frequency range 2 (FR2) of time division duplex (TDD), the number of time domain location configuration of ROs is limited, and the ROs are generally configured in UL slots, which cannot effectively configure ROs in SBFD time units and / or DL time units. In view of this, FIG. 2A is an interaction schematic diagram of a RO determination method according to an example embodiment. As shown in FIG. 2A, the embodiments of the present disclosure relate to a RO determination method for a communication system 100, and the method comprises:

[0172] S2101: The network device sends a RACH resource configuration to a UE.

[0173] In some embodiments, the network device can be an access network device, which can include, but is not limited to, an eNB and / or a gNB, etc.

[0174] In some embodiments, the RACH resource configuration is used to configure ROs. In some embodiments, the RACH resource configuration is in a SIB.

[0175] 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, the MAC layer message, or the physical layer message can include the above-mentioned RACH resource configuration.

[0176] In some embodiments, the RACH resource configuration includes at least first information. The first information is used to configure at least one first RO.

[0177] In some embodiments, the first RO can be an RO explicitly indicated by the first information in the RACH resource configuration.

[0178] In some embodiments, the RACH resource configuration can be used by a UE to determine resource location of one or more ROs. Exemplarily, the RACH resource configuration can include, but is not limited to, at least one of the following:

[0179] a PRACH configuration index, used to indicate a preamble format, a configuration period, a subframe number;

[0180] a number of PRACH slots within a subframe, a length of an RO, a Msg1-FDM, used to indicate a number of FDMed ROs, which can be an enumerated parameter, and the Msg1-FDM can take values of 1, 2, 4, or 8, etc.

[0181] The above are only examples of RACH resource configuration, and the RACH resource configuration is not limited to the above examples.

[0182] A network device sends a RACH resource configuration, and correspondingly, a UE receives the RACH resource configuration.

[0183] In some embodiments, a network device sends RACH resources to various types of UEs. For example, the network device sends a RACH resource configuration to a non-SBFD aware UE and / or a SBFD aware UE.

[0184] In some embodiments, the RACH resource configuration is used for at least one of a non-SBFD aware UE and a SBFD aware UE.

[0185] The RACH resource configuration includes at least one of the following:

[0186] time domain configuration information of the RACH resource, used to determine a time domain location of an RO;

[0187] frequency domain configuration information of the RACH resource, used to determine a frequency domain location of an RO.

[0188] In some embodiments, according to whether an RO is configured on an SBFD time unit, the ROs can be divided into SBFD time unit ROs and non-SBFD time unit ROs. The SBFD time unit can include, but is not limited to, an SBFD symbol, an SBFD mini-slot, or an SBFD slot. The number of symbols contained in an SBFD mini-slot is less than the number of symbols contained in an SBFD slot.

[0189] In some embodiments, an RO includes at least one of the following:

[0190] The first type of RO is located in a time unit which is a non-subband duplex (SBFD) time unit;

[0191] The second type of RO is located in a time unit which is at least partially a SBFD time unit within a flexible (F) time unit, and the time unit is not a SBFD time unit within a downlink (DL) time unit;

[0192] The third type of RO is located in a time unit which is at least partially a SBFD time unit within a DL time unit.

[0193] In some embodiments, the time unit where the first type of RO is located can be an UL time unit or a non-SBFD time unit of a flexible time unit.

[0194] In some embodiments, the time unit where the second type of RO is located is completely a SBFD time unit of an F time unit, and / or the time unit where the second type of RO is located is partially a SBFD time unit of an F time unit and partially located on an UL time unit.

[0195] In some embodiments, the time unit where the third type of RO is located can be partially a SBFD time unit of a DL time unit, or the time unit where the third type of RO is located is completely a SBFD time unit of a DL time unit.

[0196] In some embodiments, the flexible time unit includes at least one of: a flexible time unit configured by a TDD-UL-DL-ConfigCommon; a time unit not configured by the TDD-UL-DL-ConfigCommon; a time unit not configured by a time division duplexing-uplink-downlink dedicated (TDD-UL-DL-ConfigDedicated). In some embodiments, in a case that the network device does not send a TDD-UL-DL-ConfigCommon and / or a TDD-UL-DL-ConfigDedicated information element (IE), the time unit available to the UE is not configured by the TDD-UL-DL-ConfigCommon IE and / or the TDD-UL-DL-ConfigDedicated IE.

[0197] As shown in FIG. 2B and FIG. 2C, RO#1 is the first type of RO; RO#2 and RO#3 are the second type of RO; and RO#4, RO#5 and RO#6 are the third type of RO.

[0198] In some embodiments, the number of the first ROs can be one or more. The first ROs can be any of the first ROs, the second ROs and / or the third ROs.

[0199] S2102: The UE and the network device determine the time domain position of the at least one second RO.

[0200] In some embodiments, the second ROs are different from the first ROs. For example, the second ROs are different from the first ROs in that the frequency domain positions of the first ROs are different from the frequency domain positions of the second ROs, and / or the time domain positions of the first ROs are different from the time domain positions of the second ROs.

[0201] In some embodiments, the time domain position of the second ROs is determined according to the time domain position of the first ROs. In this way, the bit overhead of the RACH configuration can be reduced.

[0202] In some embodiments, the time domain position of the second ROs is irrelevant to the time domain position of the first ROs.

[0203] In some embodiments, the time domain position of the second ROs is determined according to at least one offset value and the time domain position of the first ROs.

[0204] If the time domain position of the second ROs is determined based on the offset value, the time domain position of the second ROs is relevant to the time domain position of the first ROs.

[0205] In some embodiments, the RACH resource configuration or the protocol has a set of offset values, which includes one or more offset values.

[0206] In some embodiments, the second ROs can also include any of the first ROs, the second ROs and the third ROs.

[0207] In some embodiments, the offset value includes at least one of the following:

[0208] M first offset values, the M first offset values being determined according to the protocol; M is any positive integer;

[0209] N second offset values, the second offset values being determined according to the third information in the RACH resource configuration, and N is any positive integer.

[0210] In some embodiments, M and N can be equal or not equal.

[0211] For example, the protocol has a first set, which includes the M first offset values.

[0212] For example, the third information is used to configure a second set, which includes the N second offset values.

[0213] In some embodiments, if the RACH resource is configured with a second offset value, the first offset value agreed by the protocol is ignored, and the second offset value is used to determine the time domain position of the second RO. If the RACH resource is not configured with the second offset value, the time domain position of the second RO can be determined according to the first offset value agreed by the protocol.

[0214] In some embodiments, the M first offset values are respectively agreed by the protocol. In this case, if the M first offset values are agreed by the protocol, the protocol gives the M first offset values in an enumeration manner.

[0215] The first offset value offset#A in the M first offset values and the number M of the first offset values are agreed by the protocol, and the other first offset values in the M first offset values are calculated according to the first first offset value. In some embodiments, M can also be indicated by the RACH resource configuration. In other embodiments, M can also be a default value, so that the protocol does not need to be specially agreed, and the RACH resource configuration also does not need to be specially configured.

[0216] In some embodiments, the xth offset value in the M first offset values is offset#A+x-1 or offset#A-(x-1); x is a positive integer less than or equal to M.

[0217] In some embodiments, if the first first offset value in the M first offset values and the number M of the first offset values are agreed by the protocol, the other first offset values can be calculated according to the first first offset value indicated by the protocol. The calculation method can be agreed by the protocol, or negotiated between the UE and the network device. For example, the calculation method is indicated in the RACH resource configuration, or a default method is used. In specific implementation, the first offset value explicitly agreed by the protocol is not necessarily the first first offset value, but can also be the last first offset value, etc.

[0218] In some embodiments, the RACH resource configuration includes a RACH configuration index; the M first offset values are related to at least one of the RACH configuration index, the TDD configuration, and the frequency range used by the UE.

[0219] The size of the first offset value agreed in the protocol is related to at least one of the RACH configuration index, the TDD configuration, and the frequency range used by the UE. In this case, the first offset value is related to the RACH resource, the resource configuration of TDD, and / or the frequency range used by the UE, and is applicable to the current RACH resource, the resource configuration of TDD, and / or the frequency range used by the UE. For example, the RACH resource indicated by the RACH resource index is widely distributed or sparsely distributed, and the first offset value can be relatively large. For another example, the resource configuration of TDD can have a certain range, and the application of the first offset value is at least within the time domain range of the resource configuration of TDD. The frequency range can include FR1 and / or FR2. Different frequency ranges used by the UE are different, and the subcarrier spacing is different, and the time domain length of a single RO can be different. In this case, the time interval between two adjacent ROs can be different, and the first offset value is also different. For example, when the TDD configuration is a first TDD configuration, the first offset value agreed in the protocol can be one of {1, 2, 3, 4}. When the TDD configuration is a second TDD configuration, the first offset value agreed in the protocol can be one of {1, 2, 3, 4, 5, 6, 7, 8, 9}. For example, when the RACH configuration index is a first index, the first offset value agreed in the protocol can be one of {1, 2, 3, 4}. When the RACH configuration index is a second index, the first offset value agreed in the protocol can be one of {1, 2, 3, 4, 5, 6, 7, 8, 9}. For example, when the frequency range in which the RACH resource is located is FR1, the first offset value agreed in the protocol can be one of {1, 2, 3, 4, 5, 6, 7, 8, 9}. When the frequency range in which the RACH resource is located is FR2, the first offset value agreed in the protocol can be one of {1, 2, 3, 4, 5, 6, 7, 8, 9, …, 38, 39}.

[0220] If the second RO is determined according to the second offset value, it is equivalent to that the network device (for example, a base station) determines the second offset value according to the current resource usage and / or the TDD configuration, and the like. In this case, the second offset value can be related to the RACH resource, the resource configuration of TDD, and / or the frequency range used by the UE, and is applicable to the current RACH resource, the resource configuration of TDD, and / or the frequency range used by the UE. Alternatively, the second offset value can not be related to the RACH resource, the resource configuration of TDD, and / or the frequency range used by the UE. In this case, the second offset value can also be related to the remaining resources currently available to the network device, and the like. Of course, the above is only an example, and the specific implementation is not limited to the above example.

[0221] In some embodiments, the RACH resource configuration can further include third information, which can be used by the UE and / or the network device to determine the second offset value.

[0222] In some embodiments, the third information can include but is not limited to at least one of the following:

[0223] the second offset value itself;

[0224] an index of the second offset value;

[0225] a value of one of the second offset values;

[0226] determine a calculation manner of other second offset values based on a known second offset value.

[0227] In some embodiments, the N second offset values are respectively configured by third information. Exemplarily, the third information indicates each of the N second offset values in an enumeration manner.

[0228] In some embodiments, a first second offset value offset#B of the N second offset values and the number N of the second offset values are configured by the third information, and other second offset values are calculated according to the first second offset value. In some embodiments, the number N of the second offset values can also be agreed by a protocol. In some embodiments, N can also be a default value, so that the protocol does not need to be specially agreed, and the third information also does not need to be specially configured.

[0229] In some embodiments, a first second offset value offset#B of the N second offset values is agreed by a protocol, and the number N of the second offset values is configured by the third information, and other second offset values are calculated according to the first second offset value.

[0230] In some embodiments, a first second offset value offset#B of the N second offset values is configured by the third information, and the number N of the second offset values is agreed by a protocol, and other second offset values are calculated according to the first second offset value.

[0231] In a specific implementation, the first offset value explicitly indicated by the third information is not necessarily the first first offset value, but can also be the last second offset value, etc.

[0232] In some embodiments, the yth offset value of the N second offset values is offset#B+y-1 or offset#B-(y-1); y is a positive integer less than or equal to N.

[0233] In some embodiments, determining the time domain position of the second RO according to the at least one offset value and the time domain position of the first RO includes but is not limited to at least one of the following:

[0234] determine a first time unit; the first RO is configured on the first time unit;

[0235] determine the time domain position of the second RO according to the at least one offset value and the first time unit.

[0236] In some embodiments, the first time unit can be determined before determining the second RO. The first time unit can be a time slot, a symbol, or a subframe. For example, the first time unit can be any time unit configured with the first RO. For another example, the first time unit can be any time unit configured with the first type of RO. The first time unit can be any time unit configured with the second type of RO. The first time unit can be any time unit configured with the third type of RO. In some embodiments, the first time unit can be a time unit containing a SBFD time unit and configured with the first RO on the SBFD time unit. In some embodiments, the first time unit can be a time unit containing a non-SBFD time unit and configured with the first RO on the non-SBFD time unit.

[0237] For example, the first time unit includes at least one of: any time unit configured with the first RO; a time unit configured with the first type of RO in the first RO; a time unit configured with the second type of RO in the first RO; a time unit configured with the third type of RO in the first RO; a time unit configured with the first type of RO and the second type of RO in the first RO.

[0238] For example, the first time unit includes at least one of: a subset of any time unit configured with the first RO; a subset of a time unit configured with the first type of RO in the first RO; a subset of a time unit configured with the second type of RO in the first RO; a subset of a time unit configured with the third type of RO in the first RO; a subset of a time unit configured with the first type of RO and the second type of RO in the first RO. The subset can be indicated by a protocol agreement, a high layer configuration, or a dynamic indication. For example, the subset can be indicated by a bitmap. The high layer configuration can be a configuration using a message above a physical layer. For example, the high layer configuration can include a RRC message configuration and / or a MAC layer message configuration. The dynamic indication can include, but is not limited to, a downlink control information.

[0239] In some embodiments, the time domain location of the second RO is determined according to at least one offset value and the first time unit, including:

[0240] According to a first time unit and Z offset values, Z second time units containing the second RO are determined; Z is the number of offset values, and Z is a positive integer.

[0241] The first time unit is a time unit in which the first RO is located, and the second time unit is a time unit in which the second RO is located. For example, the first time unit and the second time unit are a time slot, a subframe, or a radio frame. Preferably, the time unit in which the second RO is located can include an SBFD time unit, and at least part of the time domain position of the second RO is located on the SBFD time unit. In this way, by arranging the second RO on the SBFD time unit, the number of ROs can be increased, and the capacity of the RACH resource can be increased.

[0242] In some embodiments, after determining the Z second time units containing the second RO, the UE determines the time unit in which the second RO is located, and the time unit in which the second RO is located is at least partially an SBFD time unit. For example, part of the time domain position of one second RO is located on the SBFD time unit, or all of the time domain position of one second RO is located on the SBFD time unit.

[0243] In some embodiments, when the Z offset values are the first offset values, Z is equal to M.

[0244] In some embodiments, when the Z offset values are the second offset values, Z is equal to N.

[0245] In some embodiments, the time domain position of the second RO is determined according to the second information, the second information is used to determine at least one bit map, and the second information is included in the RACH resource configuration

[0246] In some embodiments, the second information includes but is not limited to at least one of the following: a bit map; an index of a bit map.

[0247] In the embodiments of the present disclosure, a bit map is introduced to indicate the time domain position of the second RO, which has the advantages of explicit indication and simple implementation.

[0248] In some embodiments, the bit map associated with the second information includes but is not limited to at least one of the following:

[0249] A first bit map, the number of bits included in the first bit map can be equal to the number of fourth time units in the third time unit, and one bit in the first bit map is used to indicate whether one fourth time unit in the third time unit is a time unit in which the second RO is configured;

[0250] A second bit map, the number of bits included in the second bit map can be less than the number of fourth time units in the third time unit, and one bit in the second bit map can indicate whether one or more fourth units in the third time unit contain the second RO;

[0251] a third bitmap and a fourth bitmap; the third bitmap and the fourth bitmap are used to determine whether a fourth unit in the third time unit contains the second RO.

[0252] Exemplarily, the fourth time unit can be a sub-time unit of the third time unit. For example, the third time unit can be a frame, and the fourth time unit can be a subframe. For example, the third time unit can be a frame, and the fourth time unit can be a slot. For example, the third time unit can be a frame, and the fourth time unit can be a slot, and the SCS of the slot is 60 KHz. For example, the third time unit can be a slot, and the fourth time unit can be a symbol.

[0253] In some embodiments, the third time unit includes one or more fourth time units. That is, the fourth time unit is a sub-time unit of the third time unit. For example, the third time unit is a subframe, and the fourth time unit can be a slot, a mini-slot, or a symbol, etc. For another example, the third time unit is a slot, and the fourth time unit is a symbol.

[0254] In the embodiments of the present disclosure, the bitmap can be used to determine the time domain position of the second RO.

[0255] In some embodiments, the bitmap is a first bitmap, and the time domain position of the second RO is determined according to the first bitmap; one bit in the first bitmap is used to indicate whether one fourth time unit in the third time unit has the second RO; and the number of bits in the first bitmap is equal to the number of fourth time units in the third time unit.

[0256] In this case, one bit in the first bitmap corresponds to whether the third time unit has a fourth time unit.

[0257] In some embodiments, the bitmap is a second bitmap, and the second bitmap has K bits; whether the L1th fourth time unit in the third time unit has the second RO is determined according to the L1 mod Kth bit of the second bitmap; K is a positive integer less than J; L1 is a positive integer; and J is the total number of fourth time units in the third time unit.

[0258] In this way, the length of the second bitmap can be shorter, and the bit overhead can be further saved.

[0259] In some embodiments, the bit map includes a third bit map and a fourth bit map, an xth bit of the fourth bit map is used to indicate whether an xth third bit map is valid; when the xth third bit map is valid, whether (x-1)*y+1th to x*yth fourth time units in the third time unit have the second RO is determined according to the xth third bit map; when the xth third bit map is not valid, it is determined that (x-1)*y+1th to x*yth fourth time units in the third time unit do not have the second RO; y is the number of bits contained in the third bit map; x is a positive integer; y is a positive integer.

[0260] Exemplarily, the third bit map and the fourth bit map are used, the length of the third bit map is L, which is less than the number J of the fourth time units in the third time unit, and the length of the fourth bit map is ceil(J / L). The fourth bit map indicates whether each of the ceil(J / L) third bit maps is valid. When an ith third bit map is valid, a J1th bit of the third bit map indicates whether (i-1)*L+J1th fourth time unit in the third time unit contains the second RO. Ceil represents rounding up, and in actual implementation, the rounding up function can also be replaced by rounding down or rounding off of decimal point digits. For example, the third time unit is a frame, and the fourth time unit is a subframe. For example, the third time unit is a frame, and the fourth time unit is a time slot, and the subcarrier spacing (SCS) of the time slot is 60 KHz.

[0261] In some embodiments, a bit of the first bit map having a first value indicates that a corresponding fourth time unit in the third time unit contains the second RO, or a bit of the first bit map having a second value indicates that the corresponding fourth time unit in the third time unit does not contain the second RO. Exemplarily, one of the first value and the second value is “1”, and the other is “0”.

[0262] In some embodiments, a bit of the second bit map having a third value indicates that a corresponding fourth time unit in the third time unit contains the second RO, or a bit of the second bit map having a fourth value indicates that the corresponding fourth time unit in the third time unit does not contain the second RO. Exemplarily, one of the third value and the fourth value is “1”, and the other is “0”.

[0263] In some embodiments, a bit of the third bit map having a fifth value indicates that a corresponding fourth time unit in the third time unit contains the second RO, or a bit of the third bit map having a sixth value indicates that the corresponding fourth time unit in the third time unit does not contain the second RO. Exemplarily, one of the fifth value and the sixth value is “1”, and the other is “0”.

[0264] In some embodiments, the UE uses frequency range FR1, the fourth time unit is a first subframe; or, the UE uses frequency range FR2, the fourth time unit is a first slot; and / or, the third time unit is a frame.

[0265] In some embodiments, the first subframe contains SBFD time units; or, the first subframe is configured with ROs and contains SBFD time units; or, the first subframe is not configured with ROs and contains SBFD time units.

[0266] In some embodiments, the first slot contains SBFD time units; or, the first subframe is configured with ROs and contains SBFD time units; or, the first subframe is not configured with ROs and contains SBFD time units.

[0267] In some embodiments, the first slot has a subcarrier spacing of 60 kHz. In some embodiments, the first slot can also have other subcarrier spacings, such as 30 kHz or 120 kHz, etc. Of course, this is just an example, and the specific implementation is not limited to this example.

[0268] In some embodiments, after determining the time unit containing the second RO, the number of second ROs in the time unit and the symbol in which the second RO is located can be determined according to the related art, which is not specifically limited here.

[0269] For example, the number of second ROs in one second time unit is the same as the number of first ROs in one first time unit. For example, the symbol in which the second RO is located in one second time unit is the same as the symbol in which the first RO is located in one first time unit. For example, the frequency domain position of the second RO in one second time unit is the same as the frequency domain position of the first RO in one first time unit.

[0270] For example, the number of second ROs in one fourth time unit is the same as the number of first ROs in one first time unit. For example, the symbol in which the second RO is located in one fourth time unit is the same as the symbol in which the first RO is located in one first time unit. For example, the frequency domain position of the second RO in one fourth time unit is the same as the frequency domain position of the first RO in one first time unit.

[0271] As shown in FIG. 3, the embodiment of the present disclosure provides a RO determination method, which is performed by a UE. The method can include:

[0272] S3101: receiving a RACH resource configuration.

[0273] In some embodiments, the UE receives a RACH resource configuration sent by the network device. Exemplarily, the RACH resource configuration comprises first information. The first information is used for configuring at least a first RO.

[0274] S3102: Determine a time domain position of the at least one second RO.

[0275] In some embodiments, how the UE specifically determines the time domain position of the RO within the SBFD time unit can refer to the corresponding embodiments of FIG. 2A.

[0276] In the embodiments of the present disclosure, the related descriptions of the first RO, the second RO, the RACH resource configuration and / or the first information can refer to the related descriptions of the corresponding embodiments of FIG. 2A.

[0277] As shown in FIG. 4, the embodiments of the present disclosure provide a RO determination method, which is performed by a network device. The method can comprise:

[0278] S4101: Send a RACH resource configuration.

[0279] In some embodiments, the network device sends a RACH resource configuration to the UE. Exemplarily, the RACH resource configuration comprises first information. In some embodiments, the RACH resource can further comprise second information or third information.

[0280] In some embodiments, the RACH resource configuration is used at least for the UE to determine the first RO based on the first information, and for the UE to determine the second RO.

[0281] Exemplarily, the RACH resource can be used for the UE to determine a time unit or a range of time units in which the second RO can be located. After determining the time unit or the range of time units in which the second RO can be located, the UE and the network device can both specifically determine the time unit containing the second RO according to the second information or the third information or a protocol agreement.

[0282] S4102: Determine a time domain position of the at least one second RO.

[0283] In some embodiments, the optional manner in which the network device determines the time domain position of the second RO can refer to any one of the optional manners of the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0284] In the embodiments of the present disclosure, the related descriptions of the first RO, the second RO, the RACH resource configuration and / or the first information can refer to the related descriptions of the corresponding embodiments of FIG. 2A.

[0285] When configuring the RACH resource for the SBFD aware UE, further indicate the SBFD sub-frames or slots containing the second RO within the radio frame.

[0286] For a fifth time unit containing the first RO in the RACH resource, one or more offset values are applied to determine one or more sixth time units containing the second RO. Exemplarily, the fifth time unit can be an alternative time unit of the aforementioned first time unit. The sixth time unit can be an alternative of the aforementioned second time unit or fourth time unit.

[0287] The number of seventh time units containing the second RO in a radio frame in the RACH resource is determined using a bitmap. Exemplarily, the radio frame is the aforementioned third time unit. In some embodiments, the seventh time unit can be an alternative of the aforementioned fourth time unit in the aforementioned embodiments.

[0288] Terminal side: SBFD aware UE determines the ROs contained in the RACH resource by the following methods.

[0289] Option 1: For a fifth time unit containing the first RO in the RACH resource, one or more offset values are applied to determine one or more sixth time units containing the second RO. Exemplarily, the sixth time unit can be a sub-time unit of the fifth time unit. The fifth time unit can be an alternative of the aforementioned third time unit.

[0290] A fifth time unit is a time unit with index N0, and a sixth time unit is determined according to offset#1 to be a time unit with index (N0±offset#1)mod X or (N0±offset#1).

[0291] The fifth time unit includes at least one of the following: a time unit of the first RO, a time unit of the first RO and / or the second RO in the first RO, a time unit of the third RO in the first RO, a time unit of the first RO, and X, where X is a value agreed by a protocol or configured by a higher layer or dynamically indicated. The higher layer configuration can be a value configured by any message above the physical layer.

[0292] Exemplarily, the value of X can be different for different frequency ranges. For example, X is 10 for FR1, and X is 40 for FR2.

[0293] Exemplarily, the fifth time unit and the sixth time unit are both slots, the fifth time unit and the sixth time unit are both subframes, or the fifth time unit and the sixth time unit are both radio frames.

[0294] Optionally, the same offset value is used for all fifth time units containing the first RO.

[0295] Optionally, one fifth time unit containing the first RO uses N offset values to determine N sixth time units containing the second RO.

[0296] The offset values can be agreed by a protocol. Alternatively, the offset values can be configured by a higher layer or indicated dynamically, and the number of offset values is N.

[0297] In some embodiments, the N offset values are respectively agreed by a protocol. In this case, if the N offset values are agreed by the protocol, the protocol gives the N offset values in an enumerated manner.

[0298] In some embodiments, the first offset value offset#A and the number of offset values N in the N offset values are agreed by a protocol, and the other offset values in the N offset values are calculated according to the first offset value.

[0299] In some embodiments, the xth offset value in the N offset values is offset#A+x-1 or offset#A-(x-1); x is a positive integer less than or equal to N.

[0300] In some embodiments, the N offset values are respectively configured by the third information. For example, the third information indicates each of the N offset values in an enumerated manner.

[0301] In some embodiments, the first offset value offset#B and the number of offset values N in the N offset values are configured by the third information, and the other offset values are calculated according to the first offset value.

[0302] In some embodiments, the first offset value offset#B in the N offset values is agreed by a protocol, the number of offset values N is configured by the third information, and the other offset values are calculated according to the first offset value.

[0303] In some embodiments, the first offset value offset#B in the N offset values is configured by the third information, the number of offset values N is agreed by a protocol, and the other offset values are calculated according to the first offset value.

[0304] In some embodiments, the yth offset value in the N offset values is offset#B+y-1 or offset#B-(y-1); y is a positive integer less than or equal to N.

[0305] Optionally, when the offset values are agreed by a protocol, the offset values can be related to at least one of a TDD configuration, a RACH configuration index, and a frequency range in which the RACH resource is located.

[0306] For example, when the TDD configuration is a first TDD configuration, the protocol agrees that the offset value is one of {1, 2, 3, 4}, and when the TDD configuration is a second TDD configuration, the protocol agrees that the offset value is one of {1, 2, 3, 4, 5, 6, 7, 8, 9}

[0307] For example, the protocol agreed offset value is one of {1, 2, 3, 4} when the RACH configuration index is the first index, and the protocol agreed offset value is one of {1, 2, 3, 4, 5, 6, 7, 8, 9} when the RACH configuration index is the second index.

[0308] For example, the protocol agreed offset value is one of {1, 2, 3, 4, 5, 6, 7, 8, 9} when the frequency range where the RACH resource is located is FR1, and the protocol agreed offset value is one of {1, 2, 3, 4, 5, 6, 7, 8, 9, …, 38, 39} when the frequency range where the RACH resource is located is FR2.

[0309] Option 2: Use a bitmap to determine the time unit containing the second RO in the radio frame in the RACH resource, for example, the position and / or number of the time unit.

[0310] Option 2-1: Use a first bitmap, the length of the first bitmap is L, which is equal to the number of seventh time units in the radio frame

[0311] Each bit of the first bitmap indicates whether a seventh time unit contains a second RO.

[0312] Option 2-2: Use a second bitmap, the length of the second bitmap is K, which is less than the number of seventh time units in the radio frame

[0313] The value of the L1 mod Kth bit of the second bitmap indicates whether the L1th seventh time unit in the radio frame contains a second RO.

[0314] Option 2-3: Use a third bitmap and a fourth bitmap, the length of the third bitmap is J, which is less than the number of seventh time units in the radio frame, and the length of the fourth bitmap is ceil(L / J).

[0315] The fourth bitmap indicates whether each of the ceil(L / J) third bitmaps is effective

[0316] When the ith third bitmap is effective, the J1th bit of the third bitmap indicates whether the (i-1)*J+J1th seventh time unit in the radio frame contains a second RO.

[0317] Option 2-2 is a special case of option 2-3.

[0318] In option 2-2, the ceil(L / J) third bitmaps are all effective, and the fourth bitmap has each value as 1, which can not be configured

[0319] Optionally, the seventh time unit is a first subframe in FR1, and the seventh time unit is a first slot with SCS = 60 KHz in FR2

[0320] Option 1: the first subframe is a subframe, and the first slot is a slot with SCS = 60 KHz

[0321] Option 2: the first subframe is a SBFD subframe, and the first slot is a SBFD slot with SCS = 60 KHz

[0322] Option 3: the first subframe is a SBFD subframe containing the first RO, and the first slot is a SBFD slot with SCS = 60 KHz containing the first RO

[0323] Option 4: the first subframe is a SBFD subframe not containing the first RO, and the first slot is a SBFD slot with SCS = 60 KHz not containing the first RO.

[0324] In the options 1 to 4, the SBFD subframe and the SBFD slot can use one of the following definitions:

[0325] Definition 2-1: the SBFD subframe is a subframe with at least one SBFD symbol, and the SBFD slot is a slot with at least one SBFD symbol.

[0326] Definition 2-2: the SBFD subframe is a subframe with all SBFD symbols, and the SBFD slot is a slot with all SBFD symbols.

[0327] The RACH resource of the option 1 and the option 2 is the first RACH resource and / or the second RACH resource.

[0328] First configuration: the first RACH resource is configured for the non-SBFD aware UE and the SBFD aware UE.

[0329] 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.

[0330] Second configuration: the second RACH resource and the third RACH resource are configured for the non-SBFD aware UE and the SBFD aware UE respectively

[0331] 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.

[0332] Optionally, the SBFD aware UE can use one or more of the first type RO, the second type RO in the second RACH resource.

[0333] Third configuration: configure the first RACH resource for non-SBFD aware UE and SBFD aware UE, and configure the third RACH resource for SBFD aware UE.

[0334] Fourth configuration: configure the second RACH resource for non-SBFD aware UE

[0335] Optionally, the SBFD aware UE can use the first type of RO in the second RACH resource, one or more types of RO in the second type of RO.

[0336] In some embodiments, the capability of the UE can include the first capability and / or the second capability.

[0337] Exemplarily, the definition of the first capability and the second capability can include multiple options, which can include the following three options exemplarily:

[0338] 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.

[0339] 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.

[0340] 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.

[0341] Wherein, the definition of the first type of RO, the second type of RO and the third type of RO is as follows:

[0342] The first type of RO: the RO containing non-SBFD symbol, and the RO not containing SBFD symbol.

[0343] The second type of RO: the RO containing SBFD (legacy F), and not containing SBFD (legacy DL).

[0344] SBFD (legacy F): TDD-UL-DL-ConfigCommon configured as F or no TDD-UL-DL-ConfigCommon configuration, and configured as SBFD symbol.

[0345] SBFD (legacy DL): TDD-UL-DL-ConfigCommon is configured as DL, and is configured as SBFD symbol. The third type of RO: the RO containing SBFD (legacy DL).

[0346] In some embodiments, the SBFD aware UE can support the first capability and the second capability, so the SBFD aware UE 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; can use one or more of the first type of RO, the second type of RO, and the third type of RO in the third RACH resource.

[0347] Base station side: the base station determines the RO contained in the RACH resource by the following method.

[0348] Option 1: for the fifth time unit containing the first RO in the RACH resource, one or more offset values are applied to determine one or more sixth time units containing the second RO.

[0349] Option 2: use a bit map to determine the information of the time unit containing the second RO in the radio frame in the RACH resource. For example, determine the time domain position and / or the number of time units containing the second RO, etc.

[0350] The base station side determines the RO in the same way as the UE, which will not be repeated here.

[0351] The RO determination method provided by the embodiments of the present disclosure can include: the SBFD aware UE determines the RO contained in the RACH resource by the following method.

[0352] Option 1: for the first time slot containing the RO in the RACH resource, one or more offset values are applied to determine one or more second time slots containing the RO.

[0353] In option 1, one example is as follows: the fifth time unit is the time slot of the first type of RO in the first RO. The RACH resource contains one fifth time unit (time slot #4), one fifth time unit containing the first RO uses two offset values, and the two sixth time units corresponding to the fifth time unit containing the first RO are N0-offset, offset is offset#1 or offset#2, and N0 is the time slot where the fifth time unit is located.

[0354] When offset#1 takes the value 2, the sixth time unit is time slot #2.

[0355] When offset#2 takes the value 3, the sixth time unit is time slot #3.

[0356] After determining the sixth time unit, the UE can use the RO within the sixth time unit or use the RO within the fifth time unit and the sixth time unit.

[0357] As shown in FIG. 5A and FIG. 5B, the fifth time unit is the slot of the first type of RO in the first RO, i.e., slot #4. Based on offset #1, it is determined that there is a second RO on slot #2. Based on offset #2, it is determined that there is a second RO on slot #1. In this way, based on one slot and two offset values, the other two slots containing the second RO can be determined. However, according to different options in option 1 used, the ROs that the SBFD Aware UE can use are different. Exemplarily, in FIG. 5A, the ROs that the SBFD Aware UE can use include: RO #2 and RO #3. In FIG. 5B, the ROs that the SBFD Aware UE can use can include: RO #1, RO #2 and RO #3.

[0358] In option 1, another example is as follows: the fifth time unit is the slot of the first type of RO and the second type of RO in the first RO, and the RACH resource contains 2 fifth time units (slot #3, #4), one fifth time unit containing the first RO uses one offset value, and two fifth time units containing the first RO correspond to one sixth time unit respectively:

[0359] When offset #1 takes the value 2, the fifth time unit is slot #4, and the sixth time unit corresponding to the fifth time unit is slot #2.

[0360] When offset #1 takes the value 2, the fifth time unit is slot #3, and the sixth time unit corresponding to the fifth time unit is slot #1.

[0361] After determining the sixth time unit, the UE can use the RO within the sixth time unit or use the RO within the fifth time unit and the sixth time unit.

[0362] As shown in FIG. 5C and FIG. 5D, the fifth time unit includes slot #3 and slot #4, and based on offset #1 with the same value, two sixth time units are obtained respectively, and the two sixth time units are slot #1 and slot #2. Exemplarily, in FIG. 5C, the ROs that the SBFD Aware UE can use include: RO #3 and RO #4. In FIG. 5D, the ROs that the SBFD Aware UE can use can include: RO #1, RO #2, RO #3 and RO #4.

[0363] Option 2: using a bit map to determine the time unit containing the second RO in the radio frame in the RACH resource.

[0364] In option 2, one specific example is as follows: the seventh time unit is the first subframe, the first subframe uses the definition of option 1, that is, the first subframe is a subframe contained in a radio frame, at this time L = 10.

[0365] In option 2, one example is shown in FIG. 5E.

[0366] In option 2-1, the length of the first bit map is L, and the value is 1010101111. The first bit map of the value can be used to indicate that the second RO is contained in the first subframes #0, 2, 4, 6, 7, 8, and 9.

[0367] In option 2-2, the length of the second bit map is K = 2, and the value is 10. The value of the L1 mod K bit of the second bit map indicates whether the L1th seventh time unit in the radio frame contains the second RO.

[0368] It can be understood that the second bit map is repeated 5 times to obtain a bit sequence with a value of 1010101010. The bit sequence can indicate that the first subframes #0, 2, 4, 6, and 8 contain the second RO.

[0369] In option 2-3, the length of the third bit map is J = 2, and the value is 10. The length of the fourth bit map is ceil(L / J) = 5, and the fourth bit map indicates whether the i th third bit map is effective.

[0370] When the value of the fourth bit map is 10011, it indicates that the 0th, 3rd, and 4th third bit maps are effective, and the 1st and 2nd third bit maps are not effective. A bit sequence with a length of 10 bits and a value of 1000001010 can be obtained. The bit sequence indicates that the first subframes #0, 6, and 8 contain the second RO.

[0371] It can be understood that option 2-2 is a special case of option 2-3. At this time, the value of the fourth bit map is all 1, indicating that the ceil(L / J) third bit maps are all effective.

[0372] In some embodiments, the bit map determines the time unit in which the second RO is contained in the RACH resource in the radio frame.

[0373] In option 2, another specific example is as follows: the seventh time unit is the first subframe, the first subframe uses the definition of option 1, that is, the first subframe is a subframe contained in a radio frame, at this time L = 10.

[0374] In option 2-2, the length of the second bit map is K = 5, and the value is 10111. The value of the L1 mod K bit of the second bit map indicates whether the L1th seventh time unit in the radio frame contains the second RO.

[0375] It can be understood that the second bitmap is repeated twice to obtain a bit sequence with a value of 1011110111. The bit sequence can represent that the second RO is contained in the first subframes #0, 2, 3, 4, 5, 7, 8, and 9.
