[0159] First, some concepts related to embodiments of the present disclosure are described.

[0160] 1. Symbol:

[0161] The abbreviation of time domain symbol, which can also be referred to as an orthogonal frequency division multiplexing (OFDM) symbol. It should be noted that the time domain symbol can also be named in combination with other multiple access manners, and the embodiments of the present disclosure do not make any limitation. For different subcarrier spacings, the time domain symbol length can be different.

[0162] In some embodiments, the symbols in one slot can include three types: downlink symbols (which can be denoted as DL symbols), uplink symbols (which can be denoted as UL symbols), and flexible symbols (which can be denoted as F symbols). Among them, the uplink symbols are only used for uplink transmission, and the downlink symbols can only be used for downlink transmission. The flexible symbol does not have a determined transmission direction, and can be used for uplink transmission or downlink transmission according to the indication of the control signaling. In some embodiments, the symbols of one slot can all be downlink symbols, or all be uplink symbols, or all be flexible symbols, or be a mixture of multiple types of symbols.

[0163] In some embodiments, the DL symbols and the F symbols can be further configured as SBFD symbols.

[0164] In some embodiments, in the embodiments of the present disclosure, the "slot" can be understood as a slot containing 14 OFDM symbols, or can be understood as a sub-slot (sub slot) containing 7 OFDM symbols, or can be understood as a mini-slot (mini slot) containing 2, 4 OFDM symbols. Of course, the "slot" described in the embodiments of the present disclosure can also include other numbers of OFDM symbols, and the embodiments of the present disclosure do not make any specific limitation.

[0165] 2、Subband:

[0166] The subband is a part of the frequency band in a carrier, that is, one or more continuous physical resource blocks (PRBs) in the frequency domain. In the embodiments of the present disclosure, the subband can also be understood as a frequency domain resource.

[0167] 3、SBFD:

[0168] In the SBFD scheme, one carrier is divided into multiple non-overlapping subbands, and the transmission directions of different subbands can be different, that is, a carrier includes a first subband and a second subband which are non-overlapping, and the transmission directions of the first subband and the second subband can be different.

[0169] It should be noted that the first sub-band and the second sub-band refer to two types of sub-bands with different transmission directions, and do not mean that only two sub-bands are included in one carrier. In an example, one carrier includes sub-band #1 and sub-band #2, where the transmission directions of the sub-band #1 and the sub-band #2 are different. Alternatively, one carrier includes sub-band #1, sub-band #2 and sub-band #3, where the transmission directions of the sub-band #1 and the sub-band #3 are the same, and the transmission directions of the sub-band #1 and the sub-band #2 are different.

[0170] 4. SBFD time unit:

[0171] The frequency resources on the SBFD time unit include sub-bands with 2 or more different transmission directions. In some embodiments, the SBFD time unit can include an SBFD slot, an SBFD symbol, etc. FIG. 2A is a schematic diagram of an SBFD slot provided according to an embodiment of the present disclosure. In FIG. 2A, the horizontal axis represents the time domain, and the vertical axis represents the frequency domain. As shown in FIG. 2A, taking the SBFD time unit as an SBFD slot for example, the time slot #1, the time slot #2 and the time slot #3 are all SBFD slots, and each time slot includes 14 SBFD symbols.

[0172] In some embodiments, the SBFD time unit is a time unit including at least one SBFD symbol.

[0173] In some embodiments, the SBFD time unit is a time unit in which all symbols are SBFD symbols.

[0174] In some embodiments, there can also be a guard band (GB) between the DL sub-band and the UL sub-band. Through the guard band, the DL sub-band and the UL sub-band are isolated in the frequency domain to reduce the interference between the DL signal in the DL sub-band and the UL signal in the UL sub-band.

[0175] In some embodiments, in the SBFD time unit, the DL sub-band is not available for UL transmission, the UL sub-band can be used for uplink transmission, and the GB can be used for uplink transmission; or the DL sub-band is not available for UL transmission, the UL sub-band can be used for uplink transmission, and the GB cannot be used for uplink transmission.

[0176] 6. Non-SBFD time unit:

[0177] The transmission directions on all frequency resources on the non-SBFD time unit are consistent. In an example, continuing to refer to FIG. 2A, the time slot #0 is a DL time slot, and the time slot #4 is a UL time slot. The DL time slot includes 14 DL symbols, and the UL time slot includes 14 UL symbols.

[0178] In some embodiments, in the SBFD symbol, the uplink frequency domain range on one CC includes the uplink frequency domain range and the downlink frequency domain range. In the non-SBFD symbol, the frequency domain range of the entire CC is only the uplink frequency domain range or the downlink frequency domain range. It can be seen that the uplink frequency domain range in the SBFD symbol and the uplink frequency domain range in the non-SBFD symbol can be different, and the downlink frequency domain range in the SBFD symbol and the downlink frequency domain range in the non-SBFD symbol can also be different.

[0179] In some embodiments, the non-SBFD time unit is a time unit including at least one non-SBFD symbol.

[0180] In some embodiments, the non-SBFD time unit is a time unit in which all symbols are non-SBFD symbols.

[0181] In some embodiments, the uplink frequency domain range can be understood as a frequency domain range on one CC that can be used for uplink transmission, and the downlink frequency domain range can be understood as a frequency domain range on one CC that can be used for downlink transmission.

[0182] In some embodiments, in the SBFD symbol, the uplink frequency domain range on the uplink bandwidth part (BWP) can refer to a frequency domain range in which the uplink BWP and the uplink frequency domain range on one CC overlap.

[0183] In some embodiments, in the SBFD symbol, the uplink frequency domain range can be understood as a frequency domain range in which the UL subband and the uplink BWP of the UE overlap, and can also be understood as a frequency domain range in which the UL subband, the GB, and the uplink BWP of the UE overlap.

[0184] In order to improve uplink coverage and throughput, sub-band full duplex (SBFD) is studied. In the SBFD scheme, one component carrier (CC, which can be referred to as a carrier) can include multiple sub-bands (SBs), and the SBs can be contiguous and non-overlapping frequency domain resources in the frequency domain. The SBs can include one UL subband and at least one DL subband, so that the UL subband and the DL subband can exist simultaneously in the same CC, i.e., simultaneous transmission and reception can be achieved on one CC.

[0185] 7、RO:

[0186] RO is a short name for a random access channel occasion, which refers to a time-frequency resource occupied by one random access. The RO can include at least one of a frequency domain resource and a time domain resource. The terminal can send a random access signal on the RO to perform random access.

[0187] In some embodiments, the random access can include contention-based random access (CBRA) and contention-free random access (CFRA). In the CBRA, there can be a case where multiple terminals use the same preamble on the same RO, and the random access signals of the multiple terminals collide, resulting in random access failure.

[0188] In some embodiments, in the SBFD symbol, the terminal can send an uplink signal on the UL subband. Therefore, configuring the RO at the SBFD symbol can increase the number of ROs compared to configuring the RO only at the UL symbol or the F symbol. Then, the terminal supporting the SBFD can perform random access on the RO configured in the SBFD symbol, reducing the access delay, and also reducing the probability of collision of random access signals of different UEs in CBRA. In an example, FIG. 2B is a schematic diagram of configuring RO in the SBFD slot according to an embodiment of the present disclosure, where the horizontal axis represents the time domain and the vertical axis represents the frequency domain. As shown in FIG. 2B, in the SBFD symbol, the physical downlink shared channel (PDSCH) can be sent on the DL subband, and the physical random access channel (PRACH) signal can be sent using the RO on the UL subband.

[0189] In some embodiments, the RO can include an additional RO and a legacy RO. In some embodiments, the RACH configuration for implementing the configuration of the additional RO can be referred to as an additional RACH configuration. In some embodiments, the RACH configuration for implementing the configuration of the legacy RO can be referred to as a legacy RACH configuration.

[0190] In some embodiments, at least two sets of RACH resources can be configured to be used for legacy UEs and UEs supporting SBFD, respectively. For example, the legacy RACH configuration can be used for legacy UEs. For example, the additional RACH configuration can be used for UEs supporting SBFD. In some cases, the RO of the legacy RACH configuration and the RO of the additional RACH configuration can overlap in the time-frequency domain. For example, the RO of the legacy RACH configuration and the RO of the additional RACH configuration can overlap on the SBFD symbol at the DL symbol and the SBFD symbol at the flexible symbol.

[0191] Therefore, in the case that the RO of the conventional RACH configuration and the RO of the additional RACH configuration overlap, it is necessary to explicitly avoid the conflict between the ROs of different RACH configurations.

[0192] FIG. 3 is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. The communication method related by the embodiment of the present disclosure can be applied to the communication system 100.

[0356] In the following, the technical solutions of the embodiments of the present disclosure are exemplarily explained through specific embodiments.

[0357] First, the terminal side is explained.

[0358] In some embodiments, the first RO in RACH Config#1 (i.e., the first RACH configuration) and the second RO in RACH Config#2 (i.e., the second RACH configuration) overlap in the time-frequency domain. The SBFD aware UE terminal determines the used RO resource by the following method.
