In this case, the access network device, the core network device, or the network device can also be configured to have all or part of the functions of the terminal.

[0088] In some embodiments, data, information, and the like can be obtained in compliance with the laws and regulations of the country in which the location is situated.

[0089] In some embodiments, data, information, and the like can be obtained after obtaining the consent of the user.

[0090] In addition, each element, each row, or each column in the table of the embodiments of the present disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0091] A carrier component (CC) is divided into a plurality of subbands (SBs) in the frequency domain on downlink (DL) or flexible (F) symbols, the plurality of SBs including one UL subband (UL SB) and at least one (1 or 2) DL subband (DL SB), and the base station can transmit DL signals in the DL SB and simultaneously receive UL signals in the UL SB. Among them, the DL or F symbol is configured by TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated or DCI2-0 as a symbol indicated as DL or F. When a symbol simultaneously contains a DL SB and an UL SB in the frequency domain, the symbol can be referred to as an SBFD symbol. Similarly, when a plurality of symbols contained in a slot include at least one SBFD symbol, the slot can be referred to as an SBFD slot. As shown in the SBFD slot diagram of FIG. 1A, slot #0 is a DL slot containing 14 DL symbols, slots #1-3 are SBFD slots each containing 14 SBFD symbols, and slot #4 is an UL slot containing 14 UL symbols. In addition, there can be a GB (guard band) between the DL SB and the UL SB to reduce interference between the DL signal in the DL SB and the UL signal in the UL SB by frequency domain isolation.

[0092] In an 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 an UL available frequency domain range, and the frequency domain range not available for UL transmission can be referred to as an UL unavailable frequency domain range. According to the above analysis, the UL frequency domain range of a non-SBFD symbol and an 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. The UL available frequency domain range refers to the UL available frequency domain range on the BWP.

[0093] Random access includes CBRA (Contention-Based Random Access) and CFRA (Contention-Free Random Access), where in CBRA, there are multiple UEs using the same preamble (preamble sequence), i.e., 2 UEs PRACH signal collision, which will cause random access failure. In SBFD symbols, UEs can send uplink signals on UL SB. Therefore, compared with configuring RO only in UL or F symbols, configuring RO in SBFD symbols can increase the number of ROs. As shown in the SBFD symbol schematic diagram of RO configuration in FIG. 1B, SBFD-aware UEs (UEs that can identify SBFD symbol configuration) can configure RO in SBFD symbols for random access, which can reduce access latency and also reduce the probability of PRACH signal collision between different UEs in CBRA.

[0094] The interference conditions are quite different on SBFD symbols and non-SBFD symbols. The power parameters of PRACH transmission can be configured differently on SBFD and non-SBFD symbols, so that SBFD-aware UEs have different transmission powers on SBFD and non-SBFD symbols: reduce the PRACH transmission power on SBFD symbols to reduce the UE-UE CLI to other UEs; increase the PRACH transmission power on SBFD symbols to overcome the impact of gNB-gNB CLI on PRACH transmission performance.

[0095] The following describes the current technical solutions related to PRACH with repetition (PRACH repetition transmission):

[0096] The network side configures the RSRP threshold corresponding to 2 / 4 / 8 times repetition, which are rsrp-ThresholdMsg1-RepetitionNum2-r18, rsrp-ThresholdMsg1-RepetitionNum4-r18, and rsrp-ThresholdMsg1-RepetitionNum8-r18.

[0097] If the RSRP threshold of the UE measured reference signal is lower than rsrp-ThresholdMsg1-RepetitionNum8-r18, 8 times repetition is used;

[0098] Otherwise, if the RSRP threshold of the UE measured reference signal is lower than rsrp-ThresholdMsg1-RepetitionNum4-r18, 4 times repetition transmission is used;

[0099] Otherwise, if the UE measures the RSRP threshold of the reference signal is lower than rsrp-ThresholdMsgl-RepetitionNum2-r18, use 2 times repetition transmission;

[0100] Otherwise, do not use repetition transmission.

[0101] Figure 1C is a schematic diagram of a 4 times PRACH repetition transmission, UE transmits PRACH on 4 valid ROs which are consecutive in time domain.

[0102] Currently, the related protocol has certain restrictions on the parameters used for N times repetition transmission: N times repetition uses the same preamble, N times repetition is in the same frequency domain range, and N times repetition uses the same power.

[0103] In the SBFD RA enhancement, there are multiple enhancement schemes:

[0104] The first configuration: configure the first RACH Config for non-SBFD aware UE and SBFD aware UE.

[0105] The second configuration: configure the second RACH Config and the third RACH Config for non-SBFD aware UE and SBFD aware UE respectively.

[0106] The third configuration: configure the first RACH Config for non-SBFD aware UE and SBFD aware UE and the third RACH Config for SBFD aware UE.

[0107] The fourth configuration: configure the second RACH Config for non-SBFD aware UE.

[0108] Under the above multiple configurations, it is necessary to clarify that in the PRACH with repetition, the RO contained in the RO Group, so as to avoid affecting the non-SBFD aware UE and reduce the transmission delay of the SBFD aware UE.

[0109] Therefore, the present disclosure provides a communication method and device, a communication system, a communication device, and a storage medium.

The communication system includes a network device and a terminal. The communication method can include the following four specific interaction modes:

[0130] FIG. 2 is one of the interaction diagrams of the communication method provided by the present disclosure, as shown in FIG. 2, the method comprises the following steps:

[0131] In step 2101, the network device sends configuration information to the first terminal.

[0132] In some embodiments, the configuration information is used to configure available random access channel occasions ROs of the first terminal and / or the second terminal, and the second terminal is a terminal configured with non-identifiable SBFD symbols.

[0133] In some embodiments, the configuration information comprises at least one of the following: first configuration information for configuring first available ROs of the first terminal and second available ROs of the second terminal, the first available ROs comprising at least one of first type ROs, second type ROs, third type ROs, and the second available ROs comprising at least one of the first type ROs and the second type ROs; second configuration information for configuring the second available ROs of the second terminal; and third configuration information for configuring the first available ROs of the first terminal.

[0134] For example, the base station sends first information to the terminal, and the first information comprises RACH resource configuration information, etc. The first information contains RACH resource configuration information, wherein the RACH resource configuration information comprises at least one of the following (1)-(4):

[0135] (1) First configuration: configuring a first RACH Config for non-SBFD aware UE and SBFD aware UE.

[0136] ROs available to SBFD aware UE: one or more of the first type ROs, the second type ROs, and the third type ROs in the first RACH Config.

[0146] The ROs available to the non-SBFD aware UE: the first type of RO in the second RACH Config, one or more of the second type of RO.

[0147] In some embodiments, the first type of RO includes ROs that are not SBFD symbols, and ROs that are not SBFD symbols; the second type of RO includes: SBFD symbols configured on flexible symbols, and does not include SBFD symbols configured on downlink symbols; the third type of RO includes SBFD symbols configured on downlink symbols.

[0148] For example, the first type of RO includes ROs of non-SBFD symbols and excludes ROs of SBFD symbols; the second type of RO includes SBFD symbols of SBFD (legacy F) and excludes ROs of SBFD (legacy DL), where SBFD (legacy F) means that SBFD is configured on F symbols (i.e., Flexible), and SBFD (legacy F) includes at least one of the following: TDD-UL-DL-ConfigCommon is configured as F, and is configured as SBFD symbols, or, no TDD-UL-DL-ConfigCommon configuration, and no TDD-UL-DL-ConfigDedicated configuration, and is configured as SBFD symbols, and SBFD (legacy DL) means that SBFD is configured on DL symbols: TDD-UL-DL-ConfigCommon is configured as DL, and is configured as SBFD symbols; and the third type of RO includes ROs of SBFD (legacy DL).

[0149] At step 2102, the first terminal and the network device respectively determine RO groups.

[0150] In some embodiments, the first terminal determines the RO group for PRACH repetition based on the configuration information.

[0151] In some embodiments, the network device determines the RO group for PRACH repetition based on the configuration information.

[0152] In some embodiments, the first terminal / network device determines the RO group for PRACH repetition based on the configuration information includes any one of the following: determining the RO group for PRACH repetition based on the first configuration information; determining the RO group for PRACH repetition based on the second configuration information and / or the third configuration information; determining the RO group for PRACH repetition based on the first configuration information and / or the third configuration information; and determining the RO group for PRACH repetition based on the second configuration information.

[0153] Specifically, the first terminal / network device determines the RO group for PRACH repetition in the following schemes:

[0154] Scheme one: determining the RO group for PRACH repetition based on the first configuration information includes: determining the RO group for PRACH repetition based on the fourth type of RO in the first configuration information.

[0155] and the third type of RO, respectively, and the fourth type of RO includes the first type of RO and the second type of RO.

[0156] For example, the RO Groups for PRACH repetition are determined on the fourth type of RO and the third type of RO of the first RACH Config respectively; wherein the fourth type of RO includes the first type of RO and the second type of RO.

[0157] For example, as shown in FIG. 6A, one RO Group is composed of 4 ROs. The terminal determines the RO Groups for PRACH repetition based on the third type of RO: 4 ROs in slots #1 and #2 form one RO Group for SSB#0; 4 ROs in slots #3 and #6 form one RO Group for SSB#1; 4 ROs in slots #7 and #8 form one RO Group for SSB#0; the RO Groups for PRACH repetition are determined based on the fourth type of RO: 4 ROs in slots #4 and #9 form one RO Group for SSB#0.

[0158] For example, the first configuration is Single RACH Config, including the first RACH Config. The RO Groups are determined based on the first configuration, including: the RO Groups for PRACH repetition are determined on the seventh type of RO, the eighth type of RO, and the ninth type of RO respectively, wherein the seventh type of RO, the eighth type of RO, and the ninth type of RO include at least one of the first type of RO, the second type of RO, and the third type of RO of the first RACH Config or do not include any RO; the intersection of each other between the seventh type of RO, the eighth type of RO, and the ninth type of RO is an empty set.

[0159] For example, the RO Groups for PRACH repetition are determined based on the second configuration information and / or the third configuration information, including at least one of the following:

[0160] The RO Groups are determined based on the fourth type of RO in the second configuration information, the fourth type of RO including the first type of RO and the second type of RO; the RO Groups are determined based on the fifth type of RO in the third configuration information and the first type of RO respectively, the fifth type of RO including the second type of RO and the third type of RO; the RO Groups are determined based on the sixth type of RO in the third configuration information, the sixth type of RO including the first type of RO, the second type of RO, and the third type of RO;

[0161] The RO Groups are determined based on the fifth type of RO in the third configuration information; the RO Groups are determined based on the third type of RO in the third configuration information.

[0162] 2.1, determine RO groups based on the fourth type of RO in the second configuration information, the fourth type of RO including the first type of RO and the second type of RO; determine RO groups based on the fifth type of RO and the first type of RO in the third configuration information, the fifth type of RO including the second type of RO and the third type of RO.

[0163] For example, the fourth type of RO of the second RACH Config determines the RO Group for PRACH repetition, as shown in the schematic diagram of scheme 2.1 in FIG. 6B, the fourth type of RO determines the RO Group for PRACH repetition: 4 ROs in slots #4 and #9 form an RO Group for SSB #0.

[0164] For example, the fifth type of RO and the first type of RO of the third RACH Config respectively determine the RO Group for PRACH repetition, the fifth type of RO determines the RO Group for PRACH repetition, as shown in the schematic diagram of FIG. 6A, 4 ROs in slots #1 and #2 form an RO Group for SSB #0; 4 ROs in slots #3 and #6 form an RO Group for SSB #1; 4 ROs in slots #7 and #8 form an RO Group for SSB #0; the first type of RO determines the RO Group for PRACH repetition: 4 ROs in slots #4 and #9 form an RO Group for SSB #0.

[0165] In the above embodiment, the ROs on SBFD (DL / F) and non-SBFD in the third RACH Config are separately determined to form RO groups.

[0166] 2.2, determine RO groups based on the fourth type of RO in the second configuration information, the fourth type of RO including the first type of RO and the second type of RO; determine RO groups based on the sixth type of RO in the third configuration information, the sixth type of RO including the first type of RO, the second type of RO and the third type of RO.

[0167] For example, the fourth type of RO of the second RACH Config determines the RO Group for PRACH repetition; the sixth type of RO of the third RACH Config determines the RO Group for PRACH repetition. Wherein, the sixth type of RO includes the first type of RO, the second type of RO and the third type of RO; at this time, one RO Group can contain ROs on SBFD symbols and ROs on non-SBFD symbols.

[0168] Optionally, scheme 2.2 is adopted if and only if the frequency domain range of ROs on SBFD symbols and non-SBFD symbols are the same.

[0169] For example, the fourth type of RO in the second RACH Config determines the RO Group for PRACH repetition, as shown in FIG. 6B, and the sixth type of RO in the third RACH Config determines the RO Group for PRACH repetition, as shown in FIG. 6C: four ROs in slots #1 and #2 form an RO Group for SSB #0; four ROs in slots #3 and #4 form an RO Group for SSB #1; four ROs in slots #6 and #7 form an RO Group for SSB #0; and four ROs in slots #8 and #9 form an RO Group for SSB #1.

[0170] In the above embodiment, the ROs on SBFD (DL / F) and non-SBFD jointly determine the RO Group in the third RACH Config.

[0171] 2.3, based on the fourth type of RO in the second configuration information, determine the RO Group, the fourth type of RO including the first type of RO and the second type of RO; based on the fifth type of RO in the third configuration information, determine the RO Group, the fifth type of RO including the second type of RO and the third type of RO.

[0172] For example, the fourth type of RO in the second RACH Config determines the RO Group for PRACH repetition; and the fifth type of RO in the third RACH Config determines the RO Group for PRACH repetition.

[0173] For example, the fourth type of RO in the second RACH Config determines the RO Group for PRACH repetition, as shown in FIG. 6B, and the fifth type of RO in the third RACH Config determines the RO Group for PRACH repetition, as shown in FIG. 6A.

[0174] For example, the fifth type of RO determines the RO Group for PRACH repetition: four ROs in slots #1 and #2 form an RO Group for SSB #0; four ROs in slots #3 and #6 form an RO Group for SSB #1; and four ROs in slots #7 and #8 form an RO Group for SSB #0.

[0175] In the above embodiments, in the third RACH Config, the ROs on SBFD (DL / F) determine the RO Group, and the ROs on non-SBFD are not available.

[0176] 2.4, based on the fourth type of RO in the second configuration information, determine the RO Group, the fourth type of RO includes the first type of RO and the second type of RO; based on the third type of RO in the third configuration information, determine the RO Group.

[0177] For example, the fourth type of RO of the second RACH Config determines the RO Group for PRACH repetition; the third type of RO of the third RACH Config determines the RO Group for PRACH repetition.

[0178] For example, the fourth type of RO of the second RACH Config determines the RO Group for PRACH repetition, which can refer to the schematic diagram as shown in FIG. 6B; the third type of RO of the third RACH Config determines the RO Group for PRACH repetition, which can refer to the schematic diagram as shown in FIG. 6A.

[0179] For example, the third type of RO determines the RO Group for PRACH repetition: 4 ROs in slots #1 and #2 form an RO Group for SSB #0; 4 ROs in slots #3 and #6 form an RO Group for SSB #1; 4 ROs in slots #7 and #8 form an RO Group for SSB #0.

[0180] In the above embodiments, in the third RACH Config, the ROs on SBFD (DL) determine the RO Group, the ROs on SBFD (F) are not available, and the ROs on non-SBFD are not available.

[0181] For example, the second configuration is the Separate RACH Config, including the second RACH Config and the third RACH Config. The determining the RO Group based on the second configuration includes: determining the RO Group for PRACH repetition on the tenth type of RO, the eleventh type of RO, the twelfth type of RO, the thirteenth type of RO, and the fourteenth type of RO, respectively; the tenth type of RO, the eleventh type of RO, the twelfth type of RO, the thirteenth type of RO, and the fourteenth type of RO include at least one of the first type of RO of the second RACH Config, the second type of RO of the second RACH Config, the first type of RO of the third RACH Config, the second type of RO of the third RACH Config, and the third type of RO of the third RACH Config, or do not include any RO; the intersection of the tenth type of RO, the eleventh type of RO, the twelfth type of RO, the thirteenth type of RO, and the fourteenth type of RO is an empty set.

[0182] For example, the third configuration is the Single RACH Config, including the first RACH Config: using the first configuration information and / or the third configuration information to determine the RO Group for PRACH repetition.

[0184] For example, the third configuration is the Single RACH Config and the Separate RACH Config at the same time, including the first RACH Config and the third RACH Config: using the first configuration information and the second configuration information to determine the RO Group for PRACH repetition in the first RACH Config and the third RACH Config, respectively.

[0185] In some embodiments, based on the first configuration information and / or the third configuration information, determining the RO group for PRACH repetition comprises at least one of: determining the RO group based on the fourth type of RO in the first configuration information; jointly determining the RO group based on the third type of RO in the first configuration information and the fifth type of RO in the third configuration information; determining the RO group based on the first type of RO in the third configuration information; jointly determining the RO group based on the third type of RO in the first configuration information and the sixth type of RO in the third configuration information; jointly determining the RO group based on the third type of RO in the first configuration information and the fifth type of RO in the third configuration information; jointly determining the RO group based on the third type of RO in the first configuration information and the third type of RO in the third configuration information.
