It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0042] In order to better understand the embodiments of the present application, the random access process related to the present application is described.

[0043] The random access process may be a contention-based random access process or a non-contention-based random access process. The random access process may be a four-step random access process (also referred to as a Type-1 random access process) or a two-step random access process (also referred to as a Type-2 random access process).

[0044] In the four-step random access process (4-step RACH), the UE first sends message 1 (message 1, MSG.1) to the network, including a preamble; after the network detects the preamble, it will send message 2 (message 2, MSG.2) or a random access response (RAR) message, including the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send message 3 (message 3, MSG.3); after receiving MSG.2, the UE confirms that at least one of the numbers of the preamble carried in MSG.2 is consistent with the number of the preamble sent by itself, and then sends MSG.3 containing contention resolution information according to the resources indicated by RAR; after receiving MSG.3, the network will send message 4 (message 4, MSG.4) containing contention resolution information; after receiving MSG.4, the UE confirms that the resolution information is consistent with that sent by itself in MSG.3, that is, the four-step random access is completed.

[0045] The network includes uplink grant (UL grant) information in the RAR to indicate the scheduling information of the MSG.3 physical uplink shared channel (PUSCH), and includes information such as the random access preamble ID (RAPID), the temporary cell radio network temporary identity (TC-RNTI), and the timing advance (TA). If the network does not receive the MSG.3 PUSCH, it can schedule the retransmission of the MSG.3 PUSCH in the TC-RNTI-scrambled physical downlink control channel (PDCCH).

[0046] For the contention random access process, different UEs randomly select preambles for transmission, so different UEs may select the same preamble to send on the same time-frequency radio resources (RACH opportunity (RACH Occasion, RO) resources), which can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR, and at this time different UEs will transmit MSG.3PUSCH according to the scheduling information in the RAR UL grant. The network decodes the PUSCH (including contention resolution information) sent by the UE on the MSG.3PUSCH scheduling resources, so the network includes the contention resolution information received in MSG.3 in MSG.4. If the contention resolution information in MSG.4 received by the UE matches the contention resolution information sent by the UE in MSG.3PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0047] If the contention resolution is unsuccessful, the UE reselects RACH resources, sends a physical random access channel (PRACH), and makes the next random access attempt.

[0048] In the two-step random access process (2-step RACH), the first step is that the UE sends message A (message A, MsgA) in the two-step random access to the network side. After receiving MsgA, the network side sends message B (message B, MsgB) in the two-step random access to the UE. If the UE does not receive MsgB within a certain period of time, the UE will accumulate the counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the UE will switch from the 2-step random access process to the 4-step random access process.

[0049] MsgA includes MsgA preamble and MsgA PUSCH. The preamble is sent on the RO for 2-stepRACH, and the PUSCH is sent on the MsgA PUSCH resources associated with the MsgA preamble and RO. MsgA PUSCH resources are a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources, and are associated with the PRACH resources in the PRACH slot.

[0050] In order to facilitate a better understanding of the embodiments of the present application, the duplex mode enhancement related to the present application is explained.

[0051] In 5G mobile communication systems, full duplex is enhanced to meet the needs of various scenarios and business requirements. The main scenarios of 5G include enhanced mobile ultra-wideband (eMBB), ultra-reliable and low latency communication (URLLC), and massive machine type of communication (mMTC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

[0052] In NR, configuring full-duplex operation can significantly improve the delay and coverage performance of the Time Division Duplex (TDD) system. For example, subband non-overlapping full-duplex (subband non-overlapping Fullduplex), because the uplink subband and the downlink subband are non-overlapping, the self-interference is small, which can reduce transmission delay and enhance coverage.

[0053] For a downlink timeslot (DL slot), the network configures the downlink (DL) bandwidth part (Band Width Part, BWP) for the UE (by TDD uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) or TDD uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated)), such as Figure 2 For an uplink (UL) time slot, the network configures the UE with a UL BWP (configured by TDD-UL-DL-ConfigurationCommon or TDD-UL-DL-ConfigurationDedicated), such as Figure 3 Time slot 4 in.

[0054] For a downlink timeslot (DL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, such as Figure 2 As shown, there are the following examples (cases):

[0055] Case 1: Configure DL BWP, such as slot 1;

[0056] Case 2: Configure DL BWP and uplink sub-band (UL sub-band), such as slot 2.

[0057] For an uplink timeslot (UL slot) (configured by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), in a full duplex scenario, such as Figure 3 As shown, there are the following examples (cases):

[0058] Case 3: Configure UL BWP, such as slot 4;

[0059] Case 4: Configure UL BWP and downlink sub-band (DL sub band), such as slot5.

[0060] For sub-band full duplex (SBFD) operation, one SBFD sub-band consists of one resource block (RB) or a set of consecutive RBs with the same transmission direction.

[0061] The time unit (e.g., slot or symbol) in which the gNB uses SBFD operation may be referred to as a SBFD time unit (e.g., slot or symbol).

[0062] An exemplary duplex mode is: the network side is full-duplex, and at the same time, uplink transmission and downlink transmission can be carried out simultaneously at different frequency domain positions. In order to avoid interference between uplink and downlink, a certain guard band (Guard Band) can be reserved between the frequency domain positions (corresponding to the duplex sub-band) corresponding to different transmission directions; the terminal side is half-duplex, that is, consistent with TDD, at the same time, only uplink transmission or downlink transmission can be carried out, and both cannot be carried out at the same time. It can be understood that in this duplex mode, the uplink transmission and downlink transmission on the network side at the same time can only be for different terminals.

[0063] Another exemplary duplex mode is: both the terminal side and the network side are full duplex, such as Figure 4 As shown, both the terminal side and the network side work in duplex mode. Specifically, for the terminal side and the network side, at the same time, uplink transmission (uplink, UL) and downlink transmission (downlink, DL) can be performed simultaneously at different frequency domain positions.

[0064] For full-duplex at the UE side, a larger guard band (GB) (larger than the GB of the base station frequency division (FD)) may be required to suppress self-interference, such as Figure 5 shown.

[0065] For a communication device, simultaneous UL reception and DL transmission will cause self-interference. In order to ensure transmission in the interfered direction, the communication device needs to have the ability to eliminate self-interference, such as reserving a guard band between the receiving band and the transmitting band, but this will reduce the UE throughput.

[0066] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0067] At present, duplex enhancement in the 5G stage mainly considers connected UEs, and the network side supports full-duplex and the UE side supports half-duplex.

[0068] In an embodiment of the present application, the duplex mode can be configured in an idle state (Idle) or a deactivated state (Inactive), or dynamically configured in a random access phase, or configured in a connected state. Specifically, the duplex configuration can be determined based on the configuration of a random access uplink resource or a set of random access uplink resources, and random access uplink transmission can be performed in the duplex mode, thereby improving the resource utilization of random access and reducing the delay of random access uplink transmission.

[0069] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0070] Figure 6 is a schematic flow chart of a method 200 for determining a duplex configuration according to an embodiment of the present application, such as Figure 6 As shown, the duplex configuration determination method 200 may include at least part of the following contents:

[0071] S210, the network side device sends random access configuration information to the terminal; wherein the random access configuration information is used to configure at least one of the following: random access uplink resources, a set of random access uplink resources; wherein the random access configuration information is associated with a duplex configuration;

[0072] S220, the terminal receives the random access configuration information from the network side device;

[0073] S230: The terminal determines a duplex configuration according to the random access configuration information.

[0074] It should be understood that Figure 6 The steps or operations of the duplex configuration determination method 200 are shown, but these steps or operations are only examples. The embodiment of the present application may also perform other operations or Figure 6 Variations of the various operations in .

[0075] In an embodiment of the present application, under the duplex configuration determined based on the random access configuration information, the terminal may support full-duplex or half-duplex, and the network side device may support full-duplex or half-duplex. For example, the network side device supports full-duplex, and the terminal supports full-duplex or half-duplex. For another example, the network side device supports half-duplex, and the terminal supports half-duplex.

[0076] In an embodiment of the present application, the terminal can determine the duplex configuration based on the configuration of the random access uplink resource or the set of random access uplink resources. The duplex configuration is more flexible, and the duplex configuration is associated with the random access uplink resource. Random access uplink transmission can be performed in duplex mode, thereby improving the resource utilization of random access and reducing the delay of random access uplink transmission.

[0077] The duplex configuration described in the embodiment of the present application may also be referred to as at least one of the following: enhanced duplex configuration, enhanced duplex mode, cross duplex (XDD), enhanced full duplex, enhanced full duplex mode. The embodiment of the present application is not limited to this.

[0078] The duplex configuration described in the embodiment of the present application may refer to: determining the uplink subband from the downlink time unit, or determining the downlink subband on the uplink time unit. Thus, duplex transmission of downlink and uplink can be realized on the downlink time unit, or duplex transmission of downlink and uplink can be realized on the uplink time unit.

[0079] In some embodiments, the random access uplink resources configured by the random access configuration information include but are not limited to at least one of the following: uplink data shared channel resources in random access, and PRACH resources in random access.

[0080] Optionally, the random access uplink resources configured by the random access configuration information include but are not limited to at least one of the following: MsgA PUSCH resources, MsgA PRACH resources, Msg.3PUSCH resources, Msg.3PRACH resources, Msg.1PUSCH resources, Msg.1PRACH resources.

[0081] Exemplarily, the uplink data sharing channel resources in random access may include but are not limited to at least one of the following: time-frequency resources of the uplink data sharing channel in random access, a DMRS sequence of the uplink data sharing channel in random access, and a DMRS port of the uplink data sharing channel in random access.

[0082] For example, the MsgA PUSCH resources may include but are not limited to at least one of the following: time-frequency resources of the MsgA PUSCH, a DMRS sequence of the MsgA PUSCH, and a DMRS port of the MsgA PUSCH.

[0083] For example, the Msg.3PUSCH resources may include but are not limited to at least one of the following: time-frequency resources of Msg.3PUSCH, DMRS sequence of Msg.3PUSCH, and DMRS port of Msg.3PUSCH.

[0084] For example, the Msg.1PUSCH resources may include but are not limited to at least one of the following: time-frequency resources of Msg.1PUSCH, DMRS sequence of Msg.1PUSCH, and DMRS port of Msg.1PUSCH.

[0085] The association relationship described in the embodiment of the present application may also be referred to as a mapping relationship, which may be an equal relationship between two signals or channel resources in a certain sense.

[0086] The MsgA PUSCH resource or MsgA PRACH resource described in the embodiment of the present application may also be referred to as MsgA resource or MsgA.

[0087] The MsgA PUSCH resource group or the MsgA PRACH resource group described in the embodiments of the present application may also be referred to as an MsgA resource group or an MsgA group.

[0088] In an embodiment of the present application, the random access uplink resource configured by the random access configuration information may include: a random access uplink resource directly configured by the random access configuration information, or a random access uplink resource in a set of random access uplink resources configured by the random access configuration information.

[0089] In the embodiment of the present application, the random access uplink resource configured by the random access configuration information can be used in an idle state (Idle) or a deactivated state (Inactive). That is, the present embodiment can support duplex configuration in an idle state (Idle) or a deactivated state (Inactive), thereby improving the resource utilization efficiency in an idle state (Idle) or a deactivated state (Inactive).

[0090] In some embodiments, the random access configuration information can be configured in an idle state (Idle) or a deactivated state (Inactive), or the random access configuration information can be dynamically configured in a random access phase. In other words, the embodiment of the present application can obtain the duplex configuration in an idle state (Idle) or a deactivated state (Inactive) or in a random access phase, and the duplex configuration is more flexible without introducing additional duplex configuration signaling.

[0091] In some embodiments, the random access configuration information can also be configured in a connected state. In other words, the embodiments of the present application can obtain duplex configuration in a connected state, which is more flexible and does not require the introduction of additional duplex configuration signaling.

[0092] In some embodiments, the above S230 may specifically include:

[0093] The terminal determines, according to the random access uplink resource on at least one downlink time unit, an uplink subband on the at least one downlink time unit;

[0094] The random access uplink resources on the at least one downlink time unit include at least one of the following: part or all of the random access uplink resources configured by the random access configuration information, and part or all of the random access uplink resources in the set of random access uplink resources configured by the random access configuration information.

[0095] This embodiment clarifies that the uplink subband on at least one downlink time unit can be determined based on the random access uplink resources on at least one downlink time unit. After the uplink subband on at least one downlink time unit is determined, the duplex configuration on the at least one downlink time unit can be known.

[0096] In some embodiments, the downlink time unit may include but is not limited to at least one of the following: orthogonal frequency-division multiplexing (OFDM) symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.

[0097] For example, taking the random access uplink resource as MsgA PUSCH resource and the downlink time unit as a downlink time slot (DLslot) as an example, the terminal can determine the uplink subband (uplink subband) in the downlink time slot through the MsgA PUSCH resource in the downlink time slot.

[0098] For another specific example, taking the random access uplink resource as MsgA PUSCH resource or MsgA PRACH resource and the downlink time unit as a downlink time slot (DL slot), the terminal can determine the uplink subband (uplink subband) in the downlink time slot through the MsgA PUSCH resource or MsgAPRACH resource in the downlink time slot.

[0099] In some embodiments, the terminal determines part or all of the physical resource blocks (PRBs) occupied by the random access uplink resources on the at least one downlink time unit as uplink subbands, wherein the random access uplink resources on the at least one downlink time unit are valid.

[0100] Exemplarily, the random access uplink resource on at least one downlink time unit is valid, which can be understood as: satisfying the mapping relationship between PRACH and the random access uplink resource on at least one downlink time unit.

[0101] For example, taking the random access uplink resource as MsgA PUSCH resource and the downlink time unit as a downlink time slot (DLslot) as an example, in all downlink time slots where MsgA PUSCH resources appear, the PRB occupied by the MsgA PUSCH resources is considered to be configured as an uplink subband (uplink subband), and the MsgA PUSCH resources are considered to be valid.

[0102] For another specific example, taking the random access uplink resource as MsgA PUSCH resource or MsgA PRACH resource, and the downlink time unit as a downlink time slot (DL slot) as an example, in all downlink time slots where MsgA PUSCH resources or MsgA PRACH resources appear, the PRB occupied by the MsgA PUSCH resource or MsgA PRACH resource is considered to be configured as an uplink subband (uplink subband), and the MsgA PUSCH resource or the MsgA PRACH resource is considered to be valid.

[0103] For example, taking the random access uplink resource as MsgA PUSCH resource and the downlink time unit as a downlink time slot (DLslot) as an example, Figure 7 As shown, in the downlink time slot n, part of the PRBs (PRBs except the guard interval) occupied by the MsgA PUSCH resource is considered to be configured as an uplink subband, and the MsgA PUSCH resource is considered to be valid.

[0104] In some embodiments, in each downlink time unit in at least one downlink time unit, part or all of the bandwidth occupied by at least one random access uplink resource adjacent to the uplink subband is a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

[0105] For example, taking the random access uplink resource as MsgA PUSCH resource and the downlink time unit as a downlink time slot (DLslot) as an example, Figure 7 As shown, in the downlink time slot n, the entire bandwidth occupied by a MsgA PUSCH resource adjacent to the uplink subband is the guard interval.

[0106] For example, taking the random access uplink resource as MsgA PUSCH resource and the downlink time unit as a downlink time slot (DLslot) as an example, Figure 8 As shown, in the downlink time slot n, part of the bandwidth occupied by a MsgA PUSCH resource adjacent to the uplink subband is the guard interval.

[0107] In some embodiments, the above S230 may specifically include:

[0108] The terminal determines, according to the random access uplink resource on at least one uplink time unit, a downlink subband on the at least one uplink time unit;

[0109] The random access uplink resources on the at least one uplink time unit include at least one of the following: part or all of the random access uplink resources configured by the random access configuration information, and part or all of the random access uplink resources in the set of random access uplink resources configured by the random access configuration information.

[0110] This embodiment clarifies that the downlink subband on at least one uplink time unit can be determined based on the random access uplink resources on at least one uplink time unit. After the downlink subband on the at least one uplink time unit is determined, the duplex configuration on the at least one uplink time unit can be known.

[0111] In some embodiments, the uplink time unit may include, but is not limited to, at least one of the following: OFDM symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.

[0112] In some embodiments, the terminal determines part or all of the PRBs other than the PRBs occupied by the random access uplink resources on the at least one uplink time unit as downlink subbands, wherein the random access uplink resources on the at least one uplink time unit are valid.

[0113] In some embodiments, in each uplink time unit of the at least one uplink time unit, part or all of the bandwidth occupied by at least one random access uplink resource adjacent to the downlink subband is a guard interval. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

[0114] Exemplarily, the random access uplink resource on at least one uplink time unit is valid, which can be understood as: satisfying the mapping relationship between PRACH and the random access uplink resource on at least one uplink time unit.

[0115] In some embodiments, the at least one random access uplink resource satisfies at least one of the following:

[0116] Satisfies the mapping relationship between PRACH and random access uplink resources and is not used to perform random access uplink transmission;

[0117] The mapping relationship between PRACH and random access uplink resources is satisfied, and when a preset condition is satisfied, the random access uplink transmission is not performed;

[0118] The mapping relationship from PRACH to random access uplink resources is not satisfied.

[0119] Specifically, this embodiment clarifies the conditions that at least one random access uplink resource where the guard interval is located satisfies, which is conducive to better utilization of the random access uplink resources.

[0120] It should be noted that the random access uplink resources that satisfy the mapping relationship from PRACH to random access uplink resources can be considered valid; and the random access uplink resources that do not satisfy the mapping relationship from PRACH to random access uplink resources can be considered not valid.

[0121] For example, the random access uplink resource is a MsgA PUSCH resource, and the mapping relationship between the PRACH and the random access uplink resource may be: a mapping relationship between the PRACH and the MsgA PUSCH resource.

[0122] For another example, the random access uplink resource is a MsgA PRACH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and MsgA PRACH resources.

[0123] For another example, the random access uplink resource is an MsgA PUSCH resource or an MsgA PRACH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and an MsgA PUSCH resource or an MsgA PRACH resource.

[0124] For another example, the random access uplink resource is a Msg.3PUSCH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and Msg.3PUSCH resource.

[0125] For another example, the random access uplink resource is a Msg.3PRACH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and Msg.3PRACH resource.

[0126] For another example, the random access uplink resource is a Msg.3PUSCH resource or a Msg.3PRACH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and a Msg.3PUSCH resource or a Msg.3PRACH resource.

[0127] For another example, the random access uplink resource is a Msg.1PUSCH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and Msg.1PUSCH resource.

[0128] For another example, the random access uplink resource is a Msg.1PRACH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and Msg.1PRACH resource.

[0129] For another example, the random access uplink resource is a Msg.1PUSCH resource or a Msg.1PRACH resource, and the mapping relationship between PRACH and the random access uplink resource may be: a mapping relationship between PRACH and a Msg.1PUSCH resource or a Msg.1PRACH resource.

[0130] In some embodiments, the preset condition includes but is not limited to at least one of the following:

[0131] The time domain or frequency domain interval between the random access uplink resource and the reference signal is less than or not greater than the first threshold;

[0132] There is a reference signal transmission in the remaining bandwidth outside the uplink subband;

[0133] There is transmission of a downlink common channel or a downlink common signal in the remaining bandwidth outside the uplink sub-band;

[0134] There is reception of a reference signal in the remaining bandwidth outside the uplink subband;

[0135] The remaining bandwidth outside the uplink sub-band is used for receiving a downlink common channel or a downlink common signal.

[0136] For example, when a preset condition is met, it is not used to perform random access uplink transmission, thereby avoiding interference of random access uplink transmission on the transmission of reference signals or downlink common channels or downlink common signals.

[0137] For example, taking the random access uplink resource as MsgA PUSCH resource and the downlink time unit as a downlink time slot (DLslot) as an example, Figure 7 or Figure 8 As shown, the remaining bandwidth outside the uplink sub-band may include the bandwidth occupied by the guard interval and the downlink sub-band.

[0138] Optionally, the first threshold may be agreed upon by a protocol, or the first threshold may be configured by a network-side device.

[0139] In some embodiments, the preset condition is pre-configured by a network side instruction, or the preset condition is agreed upon by a protocol.

[0140] In some embodiments, the random access configuration information is also used to configure a guard interval on the at least one downlink time unit or the at least one uplink time unit. Specifically, the setting of the guard interval can suppress the self-interference generated by simultaneous reception and transmission.

[0141] The reference signal described in the embodiment of the present application includes but is not limited to at least one of the following:

[0142] Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS), MsgA, MsgA PUSCH, PRACH, Tracking reference signal (TRS) (TRS is a reference signal used for time-frequency resource estimation), Sounding Reference Signal (SRS).

[0143] The SSB described in the embodiment of the present application may also be called a resource block, which includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), and other system messages.

[0144] In an embodiment of the present application, in support of enhanced duplex mode, random access uplink resources may be allowed on an uplink subband of an additionally configured downlink time unit, so a new type of random access uplink resource may appear.

[0145] In some embodiments, the random access uplink resource configured by the random access configuration information includes at least one of the following types:

[0146] Random access uplink resources existing in uplink time units;

[0147] Random access uplink resources existing in time units with flexible symbols;

[0148] A random access uplink resource present in an uplink subband of a downlink time unit;

[0149] A random access uplink resource existing in an uplink subband of a downlink time unit, and no reference signal resource exists in the downlink time unit;

[0150] A random access uplink resource existing in an uplink subband of a downlink time unit, and a reference signal resource existing in the downlink time unit;

[0151] Random access uplink resources that are not in the uplink subband of the downlink time unit.

[0152] For example, taking the random access uplink resource as a MsgA PUSCH resource or a MsgA PRACH resource, the time unit as a time slot, and the reference signal as an SSB as an example, the random access uplink resource configured by the random access configuration information includes at least one of the following types:

[0153] MsgA PUSCH resources or MsgA PRACH resources present in the uplink timeslot;

[0154] MsgA PUSCH resources or MsgA PRACH resources present in a slot with flexible symbols;

[0155] MsgA PUSCH resources or MsgA PRACH resources present in the uplink subband of the downlink timeslot;

[0156] MsgA PUSCH resources or MsgA PRACH resources existing in the uplink subband of the downlink timeslot, and no SSB resources exist in the downlink timeslot;

[0157] MsgA PUSCH resources or MsgA PRACH resources existing in the uplink subband of the downlink timeslot, and SSB resources existing in the downlink timeslot;

[0158] MsgA PUSCH resources or MsgA PRACH resources that are not in the uplink subband of the downlink timeslot.

[0159] In some embodiments, the uplink time unit may include, but is not limited to, at least one of the following: OFDM symbol, time slot, subframe, frame, microsecond, millisecond, second, minute, hour, day, week, month.

[0160] In some embodiments, the set of random access uplink resources configured by the random access configuration information satisfies at least one of the following:

[0161] Including different types of random access uplink resources;

[0162] including random access uplink resources of the same type;

[0163] Mapped to the same PRACH resource;

[0164] Mapped to different PRACH resources.

[0165] In this embodiment, the type of random access uplink resources in the set of random access uplink resources configured by the random access configuration information and the PRACH resources to which the set of random access uplink resources is mapped are clarified, so that the set of random access uplink resources can be configured more flexibly.

[0166] In some embodiments, the set of random access uplink resources configured by the random access configuration information is used to perform random access uplink repeated transmission. Optionally, the set of random access uplink resources configured by the random access configuration information is used for repeated transmission during random access initial transmission, or the set of random access uplink resources configured by the random access configuration information is used for repeated transmission during random access retransmission.

[0167] For example, taking the random access uplink resource as MsgA PUSCH resource as an example, the set of MsgA PUSCH resources configured by the random access configuration information is used for repeated transmission of MsgA or MsgA PUSCH in the random access initial transmission process, or the set of MsgA PUSCH resources configured by the random access configuration information is used for repeated transmission of MsgA or MsgAPUSCH in the random access retransmission process.

[0168] For example, taking the random access uplink resource as MsgA PRACH resource as an example, the set of MsgA PRACH resources configured by the random access configuration information is used for repeated transmission of MsgA or MsgA PRACH in the random access initial transmission process, or the set of MsgA PRACH resources configured by the random access configuration information is used for repeated transmission of MsgA or MsgAPRACH in the random access retransmission process.

[0169] For example, taking the random access uplink resource as an MsgA PUSCH resource or an MsgA PRACH resource as an example, the set of MsgA PUSCH resources or MsgA PRACH resources configured by the random access configuration information is used for repeated transmission of MsgA or MsgA PUSCH or MsgA PRACH in the random access initial transmission process, or the set of MsgA PRACH resources configured by the random access configuration information is used for repeated transmission of MsgA or MsgA PUSCH or MsgA PRACH in the random access retransmission process.

[0170] It should be noted that repeated transmission of MsgA or MsgA PUSCH refers to repeated transmission performed during each initial transmission or retransmission of MsgA or MsgA PUSCH.

[0171] In some embodiments, the random access configuration information is a common configuration information, wherein the common configuration information is used to configure the random access uplink resource on the uplink subband and the random access uplink resource on the non-uplink subband, or the common configuration information is used to configure the set of random access uplink resources on the uplink subband and the set of random access uplink resources on the non-uplink subband. For example, the random access uplink resource on the non-uplink subband may be a random access uplink resource on an uplink time unit. For another example, the random access uplink resource on the non-uplink subband may be a random access uplink resource on a time unit containing flexible symbols.

[0172] For example, taking the random access uplink resource as MsgA PUSCH resource or MsgA PRACH resource as an example, the random access configuration information is a common MsgA resource configuration. Specifically, the same MsgA resource configuration (i.e., the common MsgA resource configuration) is used to configure two possible types of MsgA PUSCH resources or MsgA PRACH resources, namely: MsgA PUSCH resources or MsgA PRACH resources on UL subband and MsgA PUSCH resources or MsgAPRACH resources on non-UL subband.

[0173] In some embodiments, the random access configuration information is two independent configuration information, wherein the two independent configuration information are used to configure the random access uplink resource on the uplink subband and the random access uplink resource on the non-uplink subband, or the two independent configuration information are used to configure the set of random access uplink resources on the uplink subband and the set of random access uplink resources on the non-uplink subband. For example, the random access uplink resource on the non-uplink subband may be a random access uplink resource on an uplink time unit. For another example, the random access uplink resource on the non-uplink subband may be a random access uplink resource on a time unit containing flexible symbols.

[0174] For example, taking the random access uplink resource as MsgA PUSCH resource or MsgA PRACH resource as an example, the random access configuration information is two independent MsgA resource configurations. Specifically, the MsgA PUSCH resource or MsgA PRACH resource on the UL subband is configured with one MsgA resource configuration; and the MsgA PUSCH resource or MsgA PRACH resource on the non-UL subband is configured with another MsgA resource configuration.

[0175] In some embodiments, the association relationship between the random access uplink resource configured by the random access configuration information and the PRACH satisfies at least one of the following:

[0176] At least two different random access uplink resources are independently associated with the PRACH;

[0177] At least two different types of random access uplink resources are independently associated with the PRACH;

[0178] At least two different random access uplink resources are associated with the PRACH;

[0179] At least two different types of random access uplink resources are associated with the PRACH;

[0180] Different random access uplink resources are independently associated with different PRACHs;

[0181] Different types of random access uplink resources are independently associated with different types of PRACH;

[0182] Different random access uplink resources are associated with different PRACHs;

[0183] Different types of random access uplink resources are associated with different types of PRACH;

[0184] The random access uplink resource is not associated with the PRACH that overlaps with it in the time domain.

[0185] Exemplarily, taking the random access uplink resource as an MsgA PUSCH resource as an example, at least two different random access uplink resources are independently associated with PRACH, for example, as follows: MsgA PUSCH resource 1 is associated with PRACH 0, MsgA PUSCH resource 2 is associated with PRACH 1, MsgA PUSCH resource 3 is associated with PRACH 0, and MsgA PUSCH resource 4 is associated with PRACH 1. In this example, a PRACH (such as MsgA PRACH) may be associated with at least two MsgA PUSCH resources as soon as possible, for example, some MsgA PUSCH resources are on the uplink subband (UL subband), and some MsgA PUSCH resources are in the normal uplink bandwidth (ULband), so that a group of MsgA PUSCH resources that are more compact in time and associated with the same PRACH can be selected, which is conducive to completing multiple MsgA PUSCH transmission / repetition with low latency.

[0186] Exemplarily, taking the random access uplink resource as an MsgA PUSCH resource as an example, at least two different types of random access uplink resources are independently associated with PRACH (such as MsgA PRACH), for example, as follows: the MsgA PUSCH resource configured on the uplink subband of the downlink slot and the uplink MsgA PUSCH resource on the uplink slot or the flexible slot are independently associated with the MsgA PRACH resource.

[0187] Exemplarily, taking the random access uplink resource as MsgA PUSCH resource as an example, at least two different types of random access uplink resources are independently associated with PRACH, for example, as follows: MsgAPUSCH resources existing in the time slot with flexible symbols are associated with PRACH 0, MsgA PUSCH resources existing in the uplink subband of the downlink time slot are associated with PRACH 1, and MsgA PUSCH resources not in the uplink subband of the downlink time slot are associated with PRACH 3; for another example, MsgA PUSCH resources existing in the time slot with flexible symbols are associated with odd-numbered PRACHs, and MsgAPUSCH resources existing in the uplink subband of the downlink time slot are associated with even-numbered PRACHs. In this example, a PRACH (such as MsgA PRACH) may be associated with at least two different types of MsgA PUSCH resources as soon as possible, for example, some MsgA PUSCH resources are on the uplink subband (UL subband), and some MsgA PUSCH resources are in the normal uplink bandwidth (UL band). In this way, a group of MsgA PUSCH resources that are more compact in time and associated with the same PRACH (such as MsgA PRACH) can be selected, which is conducive to completing multiple MsgAPUSCH transmissions / repetitions with low latency.

[0188] Exemplarily, taking the random access uplink resource as MsgA PUSCH resource as an example, at least two different random access uplink resources are associated with PRACH (such as MsgA PRACH) together, for example, as follows: relative to MsgA PRACH resources, MsgA PUSCH resources are configured, some MsgA PUSCHs are on the uplink subband of the downlink slot, and some MsgA PUSCH resources are in the normal uplink slot or flexible slot, and the PRACH (such as MsgA PRACH) and MsgA PUSCH association are performed in a certain order, without distinguishing what kind of slot the MsgA PUSCH is on. The association complexity of MsgA PRACH to MsgA PUSCH resources can be reduced, and there is no need to distinguish different types of MsgA PUSCH resources.

[0189] Exemplarily, taking the random access uplink resource as MsgA PUSCH resource as an example, different random access uplink resources are independently associated with different PRACHs (such as MsgA PRACH). In this case, mapping is performed only between MsgA PUSCH resources and MsgA PRACH in the same MsgA.

[0190] Exemplarily, taking the random access uplink resource as MsgA PUSCH resource as an example, different types of random access uplink resources are independently associated with different types of PRACH (such as MsgA PRACH). In this case, mapping is performed only between MsgA PUSCH resources and MsgA PRACH in the same type of MsgA.

[0191] Exemplarily, taking the random access uplink resource as MsgA PUSCH resource as an example, different random access uplink resources are associated with different PRACHs (such as MsgA PRACH). In this case, the MsgA PUSCH resource in a certain MsgA can be mapped with the MsgA PRACH resource in another MsgA.

[0192] Exemplarily, taking the random access uplink resource as MsgA PUSCH resource as an example, different types of random access uplink resources are associated with different types of PRACH (such as MsgA PRACH). In this case, the MsgA PUSCH resources in a certain type of MsgA can be mapped with the MsgA PRACH resources in another type of MsgA.

[0193] Exemplarily, taking the random access uplink resource as an MsgA PUSCH resource as an example, the random access uplink resource is not associated with the PRACH that overlaps with it in the time domain, for example, as follows: If the MsgA PUSCH resource overlaps with a PRACH (such as MsgAPRACH) in the time domain, the MsgA PUSCH resource is not associated with the PRACH. For example, if a PRACH (such as MsgA PRACH) appears on the same OFDM symbol as an MsgA PUSCH resource on a subband, the MsgA PUSCH resource can be considered invalid. This can reduce interference to the PRACH (such as MsgA PRACH).

[0194] Therefore, in an embodiment of the present application, the terminal can determine the duplex configuration based on the configuration of the random access uplink resource or a set of random access uplink resources, without the need for separate signaling to perform the duplex configuration. The duplex configuration is associated with the random access uplink resource, and random access uplink transmission can be performed in the duplex mode, thereby improving the resource utilization of random access and reducing the delay of random access uplink transmission.

[0195] In an embodiment of the present application, flexible duplex configuration, random access uplink resource determination and PRACH to random access uplink resource mapping can be supported in idle state (Idle) / deactivated state (Inactive), thereby reducing the delay of random access uplink transmission, and dynamically determining random access uplink resources based on random access configuration information, which can improve resource utilization to a greater extent.

[0196] The duplex configuration determination method provided in the embodiment of the present application may be executed by a duplex configuration determination device, or a processing unit in the duplex configuration determination device for executing the duplex configuration determination method. In the embodiment of the present application, the duplex configuration determination device executing the duplex configuration determination method is taken as an example to illustrate the duplex configuration determination device provided in the embodiment of the present application.

[0197] Fig. 9 FIG. 4 is a schematic block diagram of a device 300 for determining a duplex configuration according to an embodiment of the present application. Fig. 9 As shown, the duplex configuration determination device 300 includes:

[0206] In some embodiments, the at least one random access uplink resource satisfies at least one of the following:

[0226] including random access uplink resources of the same type;

[0227] Mapped to the same PRACH resource;

[0228] Mapped to different PRACH resources.

[0229] In some embodiments, the set of random access uplink resources configured by the random access configuration information is used to perform random access uplink repeated transmission.

[0230] In some embodiments, the association relationship between the random access uplink resource configured by the random access configuration information and the PRACH satisfies at least one of the following:

[0231] At least two different random access uplink resources are independently associated with the PRACH;

[0232] At least two different types of random access uplink resources are independently associated with the PRACH;

[0233] At least two different random access uplink resources are associated with the PRACH;

[0234] At least two different types of random access uplink resources are associated with the PRACH;

[0235] Different random access uplink resources are independently associated with different PRACHs;

[0237] Different random access uplink resources are associated with different PRACHs;

[0238] Different types of random access uplink resources are associated with different types of PRACH;

[0239] The random access uplink resource is not associated with the PRACH that overlaps with it in the time domain.

[0240] In some embodiments, the random access configuration information is a common configuration information, wherein the common configuration information is used to configure the random access uplink resources on the uplink subband and the random access uplink resources on the non-uplink subband, or the common configuration information is used to configure the set of random access uplink resources on the uplink subband and the set of random access uplink resources on the non-uplink subband; or,

[0241] The random access configuration information is two independent configuration information, wherein the two independent configuration information are respectively used to configure the random access uplink resources on the uplink subband and the random access uplink resources on the non-uplink subband, or the two independent configuration information are respectively used to configure the set of random access uplink resources on the uplink subband and the set of random access uplink resources on the non-uplink subband.

[0242] In some embodiments, the random access uplink resource configured by the random access configuration information includes at least one of the following:

[0243] Uplink data shared channel resources in random access, PRACH resources in random access.

[0244] In some embodiments, the transceiver unit 310 may be a communication interface or a transceiver, or an input / output interface of a communication chip or a system on chip. The processing unit 320 may be embedded in or independent of a processor of the terminal in the form of hardware.
