A method and apparatus for determining a physical random access channel transmission resource, and a terminal provided by the embodiments of this application will be described below in detail through some embodiments and application scenarios thereof in combination with the drawings.
In some implementations, a resource for PRACH repetition may overlap with a downlink subband or certain downlink symbol in an evolved duplex mode or enhanced flexible TDD mode. Therefore, in the embodiments of this application, the validity of a PRACH transmission resource is determined and/or whether to transmit on the PRACH transmission resource is determined based on at least one of a configuration of a duplex mode and a configuration of a flexible TDD mode, thus making the resource for PRACH transmission more flexible, because the resource ultimately used for PRACH transmission is determined by the validity and/or determining whether to transmit. In addition, it can also avoid conflicts caused by the situation that the terminal simultaneously performs downlink transmission and PRACH transmission on overlapping resources.
In addition, in the embodiments of this application, the PRACH transmission resource may be determined based on at least one of the configuration of the duplex mode and the configuration of the flexible TDD mode. Therefore, since the PRACH transmission resource is determined based on at least one of the configuration of the duplex mode and the configuration of the flexible TDD mode, a more flexible PRACH transmission resource may be determined, for example, a resource that does not overlap with a downlink subband or certain downlink symbol is determined as the PRACH transmission resource.

Step 201: A terminal performs a target operation of a PRACH transmission resource based on a target configuration,
The PRACH transmission resource may be a resource used for PRACH repetition, that is, the PRACH transmission resource includes a PRACH repetition resource. In addition, the PRACH transmission resource is one or more PRACH transmission resources.
The configuration of the duplex mode may be a configuration used for configuring a resource for the duplex mode, for example, a time domain resource configuration of the duplex mode or a frequency domain resource configuration of the duplex mode.
The configuration of the flexible TDD mode is a configuration used for configuring a resource for the flexible TDD mode, for example, a time domain resource configuration of the flexible TDD mode or a frequency domain resource configuration of the flexible TDD mode. Flexible TDD may refer to the existence of a flexible resource that can be used for both uplink transmission and downlink transmission.
The determining the validity of the PRACH transmission resource may be to determine whether the PRACH transmission resource is valid. A valid PRACH transmission resource can be used for PRACH transmission, and an invalid PRACH transmission resource cannot be used for PRACH transmission.
The determining the PRACH transmission resource may be to determine a resource for PRACH transmission.
In one implementation, the target operation is to determine the validity of the PRACH transmission resource. In this case, the PRACH transmission resource may be a PRACH transmission resource determined based on the target configuration, or the PRACH transmission resource may be a PRACH transmission resource configured by adopting a protocol defined manner, such as pre-configured.
In one implementation, the target operation is to determine whether to transmit on the PRACH transmission resource. In this case, the PRACH transmission resource may be a PRACH transmission resource determined based on the target configuration, or the PRACH transmission resource may be a PRACH transmission resource configured by adopting a protocol defined manner, such as pre-configured.
In one implementation, the target operation is to determine the validity of the PRACH transmission resource and determine whether to transmit on the PRACH transmission resource. In this case, the PRACH transmission resource may be a PRACH transmission resource determined based on the target configuration, or the PRACH transmission resource may be a PRACH transmission resource configured by adopting a protocol defined manner, such as pre-configured.
In one implementation, the target operation is to determine the PRACH transmission resource and determine the validity of the PRACH transmission resource.
In one implementation, the target operation is to determine the PRACH transmission resource and determine whether to transmit on the PRACH transmission resource.
It is to be noted that in the embodiments of this application, the PRACH resource may be a PRACH resource for a four-step random access channel (RACH), or a PRACH resource for a two-step RACH.
In the embodiments of this application, through the above steps, at least one of the validity of the PRACH transmission resource, whether to transmit on the PRACH transmission resource, and the PRACH transmission resource may be determined based on the target configuration, thus improving the configuration flexibility of the resource for PRACH transmission.
In an optional implementation, the method further includes:
PRACH transmission is performed based on the target operation.
For example, the PRACH is transmitted on the PRACH transmission resource determined to be valid, or the PRACH is transmitted on the PRACH transmission resource determined to perform PRACH transmission, or the PRACH is transmitted on the determined PRACH transmission resource.
In this implementation, flexible PRACH transmission can be supported to improve the transmission performance of the terminal.
As an optional implementation, the configuration of the flexible TDD mode includes a configuration of an enhanced flexible TDD mode.
As an optional implementation, the configuration of the duplex mode includes a configuration of an evolved duplex mode.
The enhanced flexible TDD mode may be a flexible TDD mode that is enhanced on the basis of a flexible TDD mode defined by certain protocols (e.g., Rel-17). The enhanced flexible TDD mode refers to a more flexible configuration of uplink and downlink resources, i.e., a more flexible TDD mode. For example, in the enhanced flexible TDD mode, a plurality of segments of uplink transmissions are supported within one slot. For example, as shown in
In addition, the configuration of the enhanced flexible TDD mode may also be referred to as a configuration supporting the enhanced flexible TDD mode.
The evolved duplex mode may be a duplex mode that is evolved on the basis of a duplex mode defined by certain protocols (e.g., Rel-17). A configuration of the evolved duplex mode is more flexible. In the present embodiment, the evolved duplex mode may also be referred to as a flexible division duplex (XDD) or non-overlapping subband full duplex mode, or may also be referred to as a cross division duplex. In the configuration of the evolved duplex mode, different subbands have different configurations at certain moments, or different subbands have different configurations at the same moment. For example, as shown in
In the embodiments of this application, one carrier may be divided into one or more BWPs, and one BWP may be divided into one or more subbands.
The configuration of the evolved duplex mode may also be referred to as a configuration supporting the evolved duplex mode.
In this implementation, since the configuration of the flexible TDD mode includes the configuration of the enhanced flexible TDD mode, and/or the configuration of the duplex mode includes the configuration of the evolved duplex mode, more flexible PRACH transmission can be supported.
It is to be noted that in the embodiments of this application, the configuration of the flexible TDD mode is not limited to include the configuration of the enhanced flexible TDD mode, and may also include a configuration of a non-enhanced flexible TDD mode; and the configuration of the duplex mode is not limited to include the configuration of the evolved duplex mode, and may also include a configuration of a non-evolved duplex mode.
As an optional implementation, the determining the validity of the PRACH transmission resource includes:
In this implementation, the validity of the PRACH transmission resource in the case of CBRA may be determined, so as to avoid conflicts in the PRACH transmission resource in the case of CBRA; and the validity of the PRACH transmission resource in the case of CFRA may be determined, so as to avoid conflicts in the PRACH transmission resource in the case of CFRA.
Optionally, the configuration of the duplex mode includes a configuration of a cell specific duplex mode, a configuration of a UE specific full duplex mode, a configuration of a cell specific full duplex mode, or a configuration of a semi-static full duplex mode; and
The configuration of the cell specific duplex mode may include a configuration of a duplex mode defined by certain protocols, and the cell specific full duplex mode may be a configuration of an evolved cell specific full duplex mode.
The configuration of the flexible TDD mode may be a configuration of a cell specific flexible TDD mode, or a configuration of a UE specific flexible TDD mode.
The determining the validity of the PRACH transmission resource in the case of CBRA may be to determine that the PRACH transmission resource overlapping with a downlink (DL) subband or DL symbol is valid, or determine that the PRACH transmission resource overlapping with the DL subband or DL symbol is invalid, where the DL subband and DL symbol are resources of at least one of the configuration of the duplex mode and the configuration of the flexible TDD mode.
In this implementation, since the validity of the PRACH transmission resource in the case of CBRA is determined, the valid PRACH transmission resource can be determined, thus improving the utilization rate of the resource and avoiding the waste of synchronization signal block (SSB) resources caused by the mapping of SSB to some practically unusable PRACH transmission resources.
For example, in some embodiments, the validity of the PRACH repetition resource may be based solely on the configuration of the cell specific duplex mode (including the configuration of the duplex mode defined by certain protocols and/or the configuration of the evolved full duplex mode and/or the configuration of the enhanced flexible TDD mode), thus improving the utilization rate of the resource and preventing SSB from mapping to some practically unusable PRACH resources.
Optionally, the terminal indicates through the PRACH that the terminal supports at least one of:
Indicating that the terminal supports at least one of the capabilities when sending the PRACH may be to indicate at least one of the capabilities through the resource for sending the PRACH or a preamble of the PRACH.
The resource for sending the PRACH may be a specific PRACH resource, such as a PRACH resource including a physical random access channel transmission occasion (PRACH transmission occasion, RO).
Indicating that the terminal supports at least one of the capabilities when sending the PRACH may be to indicate that the terminal supports at least one of the capabilities when sending the PRACH in the case of CBRA.
In this implementation, by indicating at least one of the capabilities when sending the PRACH, that is, when the terminal transmits the PRACH through the PRACH resource, the network side can determine at least one of the capability of the terminal in supporting the evolved full duplex mode and the capability in supporting the enhanced flexible TDD mode.
In this implementation, by indicating at least one of the capabilities when sending the PRACH, the network-side device can be informed of the capabilities of the terminal, so as to better communicate with the terminal based on the capabilities of the terminal, thus improving the communication performance of the terminal.
For example, in some embodiments, in a case that the capability of the terminal in supporting the evolved full duplex mode and/or the capability in supporting the enhanced flexible TDD mode is indicated through an additional PRACH resource, the additional PRACH resource may also include a resource for indicating PRACH repetition. In this case, the validity of the resource for sending PRACH repetition may be determined based on the configuration of the cell specific or semi-static evolved full duplex mode and/or the configuration of the enhanced flexible TDD.
It is to be noted that in the embodiments of this application, a specific preamble, or a specific initial BWP, or a specific subband may also be used for indicating that the terminal supports at least one of the capabilities.
Optionally, the configuration of the duplex mode includes the configuration of the cell specific full duplex mode or the configuration of the semi-static full duplex mode, and the determining the validity of the PRACH transmission resource includes:
The configuration of the flexible TDD mode may be a configuration of a dynamic or semi-static flexible TDD mode. In addition, the configuration of the flexible TDD mode may be the configuration of the cell specific flexible TDD mode, or the configuration of the UE specific flexible TDD mode.
The determining the validity of the PRACH transmission resource in the case of CFRA may be to determine that the PRACH transmission resource overlapping with a DL subband or DL symbol is valid, or determine that the PRACH transmission resource overlapping with the DL subband or DL symbol is invalid, where the DL subband and DL symbol are resources of at least one of the configuration of the duplex mode and the configuration of the flexible TDD mode.
In this implementation, since the validity of the PRACH transmission resource in the case of CFRA is determined, the valid PRACH transmission resource can be determined, thus improving the utilization rate of the resource and avoiding the waste of the SSB resources caused by the mapping of SSB to some practically unusable PRACH transmission resources.
For example, in some embodiments, the validity of the RO may be determined based on the configuration of the cell specific or semi-static evolved full duplex mode and/or the configuration of the enhanced flexible TDD.
In the embodiments of this application, for CFRA, the network side may determine whether the terminal has the capability to support the evolved full duplex mode and/or support the enhanced flexible TDD mode through the terminal's capability report in a radio resource control (RRC) connected state.
As an optional implementation, the determining whether to transmit on the PRACH transmission resource includes:
In a case that it is determined to transmit on the PRACH transmission resource, the terminal transmits the PRACH on the PRACH transmission resource. In a case that it is determined not to transmit on the PRACH transmission resource, the terminal abandons transmitting the PRACH on the PRACH transmission resource.
In this implementation, since whether to transmit on the PRACH transmission resource in the case of contention based random access CBRA can be determined, errors in PRACH transmission can be avoided, thus improving the transmission performance of the PRACH.
Optionally, the configuration of the duplex mode includes at least one of a configuration of a UE specific full duplex mode and a configuration of a dynamic full duplex mode, and the determining whether to transmit on the PRACH transmission resource in the case of contention based random access CBRA includes:
The configuration of the UE specific full duplex mode may be a configuration of a UE specific evolved full duplex mode.
In this implementation, whether to actually transmit on the PRACH transmission resource in the case of CBRA can be accurately determined based on at least one of the configuration of the UE specific full duplex mode and the configuration of the flexible TDD mode.
The configuration of the dynamic full duplex mode may be a configuration of a full duplex mode indicated by downlink control information (DCI) or media access control control element (MAC CE). In addition, the configuration of the flexible TDD mode may also be a configuration of a dynamic flexible TDD mode, such as a configuration of a flexible TDD mode dynamically indicated by DCI or MAC CE.
In this implementation, whether to actually transmit on the PRACH transmission resource in the case of CBRA can be accurately determined based on at least one of the configuration of the dynamic full duplex mode and the configuration of the flexible TDD mode.
Optionally, in a case that DCI or MAC CE indicates at least one of the configuration of the full duplex mode and the configuration of the flexible TDD mode, the terminal abandons sending the PRACH on a first PRACH transmission resource, or the terminal sends the PRACH on the first PRACH transmission resource.
The first PRACH transmission resource overlaps with a downlink subband resource, or the first PRACH transmission resource overlaps with a downlink time domain resource.
The downlink time domain resource may be a downlink symbol.
The terminal may determine based on a network-side configuration: to abandon sending the PRACH on the first PRACH transmission resource, or to send the PRACH on the first PRACH transmission resource; or
The DCI may be group-common DCI or UE specific DCI.
In this implementation, whether to transmit on the PRACH transmission resource may be flexibly determined, so as to support more flexible PRACH transmission.
For example, in some embodiments, in a case that the configuration of the evolved full duplex mode and/or the configuration of the enhanced flexible TDD mode dynamically indicated by DCI or MAC CE is used, the terminal may abandon sending the PRACH on the resource indicated as a downlink subband or downlink symbol, or the terminal may continuously send the PRACH on the resource indicated as the downlink subband or downlink symbol, and in this case, the resource indicated as the DL resource is still considered as an uplink resource.
Whether to abandon the PRACH transmission may be further determined based on a network configuration or terminal implementation; or
In the embodiments of this application, some repetitions of the PRACH transmission may be transmitted on a shared RO, and the remaining portion of the PRACH repetitions may be transmitted on an additionally configured RO. That is, the PRACH transmission resource may include a shared RO and an additionally configured RO. In this case, the validity of the PRACH transmission resource and whether to actually transmit the PRACH may have the same rule or different rules to the shared RO and the additionally configured RO. For details, reference may be made to the following implementations.
As an optional implementation, in a case that the PRACH transmission resource includes a shared RO and an additionally configured RO, the determining the validity of the PRACH transmission resource includes:
In the embodiments of this application, the shared RO may be an RO that can send both repeated and non-repeated PRACH, that is, the initial transmission and repetition of PRACH may both be performed on the shared RO, and the additionally configured RO is an RO additionally configured on the basis of the shared RO and may be specifically for PRACH repetition, that is, the additionally configured RO is used for the repetition of the additionally configured RO.
The situation that the RO overlaps with the downlink time domain resource determined by the configuration of the flexible TDD mode may be that the RO partially or fully overlaps with the downlink time domain resource determined by the configuration of the flexible TDD mode.
In this implementation, it can be determined that at least one of the RO is invalid, thus avoiding conflicts between PRACH and downlink transmission. In addition, in this implementation, in a case that the shared RO falls within at least one of the above cases, whether the shared RO is valid or invalid may be determined.
For example, in some embodiments, the additionally configured resource for PRACH repetition is invalid in one or more of the following cases:
As an optional implementation, in a case that the PRACH transmission resource includes a shared RO and an additionally configured RO, the determining the PRACH transmission resource includes:
In this implementation, the shared RO and the additionally configured RO may be configured in the uplink subband and flexible subband, so that the RO can be prevented from conflicting with the downlink resource, so as to improve the transmission reliability of PRACH.
For example, in some embodiments, for the full duplex mode or flexible duplex mode, the PRACH transmission resource semi-statically configured by higher-layer signaling is only within the uplink subband or flexible subband, that is, the PRACH transmission resource cannot be configured in the downlink subband or guardband.
As an optional implementation, in a case that the PRACH transmission resource includes a shared RO and an additionally configured RO, the shared RO is configured to transmit first N PRACHs in a PRACH repetition and the additionally configured RO is configured to transmit remaining PRACHs in the PRACH repetition, the determining whether to transmit on the PRACH transmission resource includes:
The downlink time domain resource may be a downlink symbol.
In this implementation, it can be determined that at least one of the ROs abandons PRACH transmission, thus avoiding conflicts between PRACH and downlink transmission. In addition, in this implementation, in a case that the shared RO falls within at least one of the above cases, whether to transmit or not to transmit PRACH on the shared RO may be determined.
Optionally, the method further includes:
The situation that the terminal determines whether the RO that abandons the PRACH transmission is mapped to the shared RO according to a configuration mode of at least one of the downlink subband, the guardband and the downlink time domain resource may be to determine that the RO that abandons the PRACH transmission is not mapped to the shared RO in a case that at least one of the downlink subband, the guardband and the downlink time domain resource is a configuration of a cell specific evolved full duplex mode, or determine that the RO that abandons the PRACH transmission is not mapped to the shared RO in a case that at least one of the downlink subband, the guardband and the downlink time domain resource is a configuration of an enhanced flexible TDD mode. In other cases, it may be mapped.
The determining whether the RO that abandons the PRACH transmission is mapped to the shared RO according to the access mode of the PRACH may be to determine that it is not mapped in the case of CBRA and it is mapped in the case of CFRA.
In this implementation, since whether the RO that abandons the PRACH transmission is mapped to the shared RO can be determined, it can support the PRACH transmission resource with higher flexibility.
In some embodiments, in a case that the first or first several PRACH repetitions are transmitted in the shared RO (that is, both repeated PRACH and non-repeated PRACH sequences can be sent), and the remaining PRACH repetitions are transmitted in separate ROs (that is, the additionally configured RO), and it at least partially overlaps with a downlink subband and/or guardband and/or downlink symbol, there may be one or more of the following rules:
One of the above two situations depends on whether the downlink subband and/or guardband and/or downlink symbol is configured specifically by a cell, for example, the overlapping RO determined by the configuration of the cell specific evolved full duplex mode and/or the configuration of the cell specific enhanced flexible TDD mode is considered not to be mapped to the shared RO;
As an optional implementation, the determining the PRACH transmission resource includes:
The flexible TDD time domain resource may be a flexible TDD slot, or a flexible TDD subframe, or a flexible TDD subslot.
The start sub time domain resource index may be a resource index used for determining a start time domain position of a resource (specifically at least one RO) for PRACH transmission. For example, the start sub time domain resource index may be a start symbol index, so that a start symbol of the resource for PRACH transmission can be determined through the start symbol index; or, in some implementations, it may also be a start subslot index or the like, which is not limited here. Through the plurality of start sub time domain resource indexes, a plurality of resources for PRACH transmission can be determined, that is, the PRACH transmission resources determined based on the plurality of start sub time domain resource indexes are a plurality of resources for PRACH transmission, such as a plurality of sets of ROs. Each set of ROs includes at least one RO.
The determining the PRACH transmission resource based on the plurality of start sub time domain resource indexes may be to determine at least one RO based on each start sub time domain resource index, and the numbers of ROs for PRACH repetition corresponding to the start sub time domain resource indexes may be the same or different. For example, the determining the PRACH transmission resource based on the plurality of start sub time domain resource indexes may be to determine the PRACH transmission resource based on the plurality of start sub time domain resource indexes and one number of ROs for PRACH repetition, that is, the numbers of ROs reached by each start sub time domain resource index are the same; or, the determining the PRACH transmission resource based on the plurality of start sub time domain resource indexes may be to determine the PRACH transmission resource based on the plurality of start sub time domain resource indexes and the plurality of numbers of ROs for PRACH repetition, that is, the numbers of ROs reached by each start sub time domain resource index are different.
The plurality of numbers of ROs for PRACH repetition may be the same or different numbers of ROs for PRACH repetition.
In this implementation, a plurality of PRACH transmission resources can be determined based on the plurality of start sub time domain resource indexes or one start sub time domain resource index and the plurality of numbers of ROs for PRACH repetition, thus improving the transmission performance of the PRACH.
It is to be noted that the plurality of start sub time domain resource indexes may be dynamically configured or pre-configured on the network side, or determined through looking up a table; and the one start sub time domain resource index and the plurality of numbers of ROs for PRACH repetition may be dynamically configured or pre-configured on the network side, or determined through looking up a table.
Optionally, the flexible TDD time domain resource is a flexible TDD slot, and the start sub time domain resource index is a start symbol index,
In this implementation, more ROs can be determined based on start symbol indexes, thus improving the transmission performance of the PRACH.
For example, in some embodiments, for enhanced flexible TDD slots, a resource for PRACH repetition may be determined by adopting the following manner:
For example, as shown in Table 1 and
NtRA,slot represents the number of ROs for PRACH repetition in one PRACH slot, and NdurRA represents the number of PRACH consecutive symbols.
Optionally, in a case that the PRACH transmission resource is determined based on one start sub time domain resource index and a plurality of numbers of ROs for PRACH repetition,
The first RO is one or more ROs determined based on the start sub time domain resource index and the first number of ROs for PRACH repetition.
In this implementation, the second RO can be determined based on the first available symbol after the first RO, so that too excessive start sub time domain resource indexes can be prevented from being introduced, thus reducing the complexity.
For example, in some embodiments, for enhanced flexible TDD slots, a resource for PRACH repetition may be determined by adopting the following manner:
For example, as shown in Table 2 and
In the embodiment of this application, the terminal performs a target operation of a PRACH transmission resource based on a target configuration, where the target configuration includes at least one of: a configuration of a duplex mode and a configuration of a TDD mode; and the target operation includes at least one of: determining the validity of the PRACH transmission resource; determining whether to transmit on the PRACH transmission resource; and determining the PRACH transmission resource. In this way, at least one of the validity of the PRACH transmission resource, whether to transmit on the PRACH transmission resource, and the PRACH transmission resource can be determined based on the target configuration, thus improving the configuration flexibility of the resource for PRACH transmission.
