Description

[Technical field]

[0001] The present invention relates to the field of communications, and in particular to a data transmission method, apparatus and electronic device. [Background technology]

[0002] Conventional Time-Division Duplex (TDD) communication systems usually operate in HD (Half-Duplex) mode. The TDD frame structure can be divided into DL (DownLink) slots, S (Special) slots and UL (UpLink) slots, among which S slots can be used for UL, DL or GP (Guard Period). In the current 5G commercial network, in order to improve the network throughput, many DL slots are generally set and relatively few UL slots are set, which limits the uplink transmission speed and increases the uplink transmission delay.

[0003] FD (Full-Duplex) communication allows simultaneous transmission and reception, i.e., uplink and downlink data transmission can be performed simultaneously. From the perspective of standardization, the 3GPP (registered trademark) protocol group has already designated FD communication as a research item and has officially begun standardization work. Operators and terminal manufacturers are also researching various key technologies for FD communication. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The terms used in the embodiments of the present invention are merely for describing specific embodiments and are not intended to limit the present invention.

It should also be understood that the term "and / or" used in the present invention means to include any or all possible combinations of one or more associated listed items.

[0012] In the embodiments of the present invention, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that the information is not limited to these terms. These terms are used only to distinguish between the same types of information. For example, the first information may be called the second information, and similarly, the second information may be called the first information, without departing from the scope of the present invention. Depending on the context, the word "when" used may be interpreted as "with," "when," or "in response to the determination."

[0013] Hereinafter, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

[0014] In a TDD communication system, time domain resources are used to distinguish between downlink and uplink, and therefore the time allocated to the uplink is limited, resulting in reduced cell coverage, increased transmission delay, and insufficient uplink capacity, which are problems present in current TDD communication systems. In addition, the conventional 5G NR system only considers the allocation of time-frequency domain resources for physical channels in TDD HD mode, and does not consider how to transmit uplink physical channels in time-frequency domain resources in TDD FD mode, or how user equipment (UE) performs uplink random access in TDD FD mode.

[0015] Therefore, the present invention mainly focuses on a method for a UE to perform uplink random access in TDD FD mode, and provides a random access method and transmission criteria for a UE in TDD FD mode, so as to ensure that an FD UE can access the NR system smoothly and efficiently, and also ensure that the access and data transmission of existing terminals are not affected.

[0016] In one embodiment of the present invention, a novel data transmission method is provided for a UE supporting subband full duplex SBFD mode. As shown in Figure 1, the method includes the following steps 101 to 103.

[0017] In step 101, an SBFD time-frequency resource corresponding to a target slot and a target time-frequency resource related to the target slot are determined based on configuration information sent from a base station.

[0018] In step 102, a data transmission operation corresponding to the target time-frequency resource is determined based on an overlap result between the SBFD time-frequency resource corresponding to the target slot and a target time-frequency resource related to the target slot.

[0019] In step 103, the determined data transmission operation is performed in the target slot.

[0020] In the technical solution of the present invention, full-duplex communication is realized by the manner of Sub-Band Full Duplex (SBFD). Specifically, in the time-frequency resources in the current TDD mode, some SBFD time-frequency resources are set so that the SBFD time-frequency resources can transmit data in a different direction from other time-frequency resources (uplink time-frequency resources or downlink time-frequency resources) at the same time.

[0021] The configuration of SBFD time-frequency resources is flexible and is generally performed by a base station in a semi-static manner or a dynamic manner. If configured in a semi-static manner, the base station may transmit the configuration information to the UE through system signaling (e.g., broadcast signaling or RRC signaling); if configured in a dynamic manner, the base station may transmit the configuration information to the UE through downlink control information (DCI). A UE that supports SBFD (abbreviated as SBFD UE) can identify the configuration of SBFD time-frequency resources from the received system signaling or DCI, and a UE that does not support SBFD (abbreviated as Legacy UE) does not expect the base station to configure SBFD resources for itself, and even if the base station configures them, the Legacy UE directly ignores the configuration and performs network access and communication according to the traditional communication mode. For more information on SBFD, please refer to R1-2203157 and R1-2203204 in the 3GPP (registered trademark) TSG-RAN WG1 conference materials.

[0022] In step 101, the UE supporting SBFD obtains configuration information sent from the base station. Based on the configuration information, the SBFD time-frequency resource configuration unit (e.g., slot or minislot), which slot is configured, configuration period, application range (e.g., UL slot, DL slot, S slot, or a combination thereof), and other time-frequency resource related configurations can be determined. The "target slot" is the UL slot, DL slot, or S slot in which the SBFD time-frequency resource is configured. Taking the UL slot as an example, the SBFD time-frequency resource may be configured to all UL symbols or some UL symbols of the UL slot. From the frequency domain, for each UL symbol, the SBFD time-frequency resource may occupy at least one physical resource block PRB in the symbol. The physical resource block may be defined within a partial bandwidth BWP (partial bandwidth), which is a resource used for actual transmission, and within each BWP, the physical resource block is numbered according to a predefined index rule. The DL slot and S slot are similar to the UL slot.

[0023] The UE can determine a target slot based on the configuration information, and the target slot may be understood as a currently focused slot, and may be any slot with a SBFD time-frequency resource configured. The target time-frequency resource associated with the target slot is a time-frequency resource that conforms to a conventional 5G communication mechanism, and may include an uplink time-frequency resource for transmitting uplink data, a downlink time-frequency resource for transmitting downlink data, or both an uplink time-frequency resource and a downlink time-frequency resource. For example, the target time-frequency resource may be an RO time-frequency resource corresponding to a random access channel opportunity RO (RACH Occasion), an SSB time-frequency resource corresponding to a synchronization signal block SSB, or both an RO time-frequency resource and an SSB time-frequency resource, and the like, which are not listed here. According to actual circumstances, some resources in the target time-frequency resource may be located in another slot different from the target slot, for example, in a two-step random access procedure, the MsgA RO time-frequency resource and the MsgA PUSCH time-frequency resource are located in different slots. The association between the SBFD time-frequency resource, the target time-frequency resource, and the target slot can be determined by configuration information transmitted from the base station.

[0024] In step 102, the UE determines a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource corresponding to the target slot and the target time-frequency resource related to the target slot.

[0025] In the embodiment of the present invention, the overlap / non-overlap between the SBFD time-frequency resource and the target time-frequency resource (uplink / downlink time-frequency resource) mainly means the overlap / non-overlap in the frequency domain, and does not consider the overlap situation in the time domain. Because the SBFD mode introduces subband duplex technology in the TDD communication system, only the target time-frequency resource and the SBFD time-frequency resource are distinguished in the frequency domain, and no collision with the SBFD time-frequency resource occurs. In addition, in the embodiment of the present invention, regarding the overlap between the uplink time-frequency resource and the downlink time-frequency resource, the overlap may be the overlap in the time domain, the frequency domain, or the time-frequency domain, and the non-overlap between the uplink time-frequency resource and the downlink time-frequency resource means the non-overlap in either the time domain or the frequency domain.

[0026] In this step, a data transmission mechanism suitable for the SBFD mode is determined by considering the collision situation between the SBFD time-frequency resource and the time-frequency resource set according to the traditional communication mechanism.

[0027] Although the 3GPP protocol group has proposed a related draft for the SBFD mode, the draft merely increases the use of SBFD time-frequency resources based on the conventional 5G communication system, and does not change the policies for resource scheduling and channel transmission, etc., except for the part related to the setting of SBFD time-frequency resources. That is, the conventional draft for the SBFD mode does not consider the problem that the use of SBFD time-frequency resources may conflict with existing policies. However, the data transmission method of this example considers the overlap situation between the time-frequency resources actually used by the uplink / downlink channels and signals and the set SBFD time-frequency resources, and provides a clear data transmission policy for the full-duplex communication system based on the SBFD mode, thereby realizing full-duplex communication based on SBFD between the UE and the base station.

[0028] Above, a data transmission method according to an embodiment of the present invention has been described with reference to Fig. 1. Below, each step of the data transmission method will be further described based on a specific example of uplink / downlink channel transmission.

[0029] The UE needs to perform a random access procedure to transmit uplink channels. The random access procedure is a necessary process to establish a radio link between the UE and the network. If the random access procedure is not completed, the data exchange operation between the UE and the base station cannot be performed normally. The UE can achieve two basic functions through the random access procedure: 1) obtain uplink synchronization with the base station, and when the uplink synchronization is lost, the UE can only transmit data on the PRACH; and 2) apply for uplink resources (UL_GRANT).

[0030] A general random access procedure can be divided into four-step random access and two-step random access. Hereinafter, the channel transmission in SBFD mode will be described based on four-step random access and two-step random access. In the following description, the specific random access procedure will not be described in detail, considering the design of the data transmission mechanism in SBFD mode, mainly due to the collision between the uplink / downlink time-frequency resource related to random access and the SBFD time-frequency resource.

[0031] Four-step random access transmission method in SBFD mode In step 1 of the four-step random access procedure, the UE sends a message (MSG1) to the base station, which is a random access signal (i.e., a preamble) transmitted by a random access channel opportunity RO. The technical solution of the present invention formulates a policy corresponding to the transmission of the RO channel in SBFD mode.

[0032] First, a case will be described where only the RO channel overlaps with the SBFD time-frequency resource, in which case the target time-frequency resource mentioned in step 102 above may be the time-frequency resource occupied by the RO channel (hereinafter referred to as the RO time-frequency resource). One target slot may have one or more ROs configured, and a data transmission mechanism based on the SBFD mode will be described with any one of the ROs as the target RO.

[0033] Specifically, the determining step performed in step 102 includes: if the overlap result is that the RO time-frequency resource is located within the SBFD time-frequency resource, determining that the data transmission operation corresponding to the target time-frequency resource is to transmit a random access signal carried by the target RO in the RO time-frequency resource if the symbol corresponding to the SBFD time-frequency resource is an uplink UL symbol or a flexible-F symbol; and determining that the data transmission operation corresponding to the target time-frequency resource is to prohibit transmitting the random access signal if the symbol corresponding to the SBFD time-frequency resource is a downlink DL symbol.

[0034] Figure 2 is a schematic diagram showing the overlap between SBFD time-frequency resource and target time-frequency resource. As shown in Figure 2, the RO time-frequency resource where RO is located and the SBFD time-frequency resource are in a completely overlapping state, that is, the RO time-frequency resource is located in the SBFD time-frequency resource. At this time, if the SBFD time-frequency resource is set on the UL symbol or the F symbol, the RO is valid, and the UE can transmit a random access signal by the SBFD time-frequency resource (the part corresponding to the RO time-frequency resource). If the SBFD time-frequency resource is set on the DL symbol, the RO is invalid, and the UE is prohibited from transmitting a random access signal by the RO.

[0035] In one example of the present invention, the determining step performed in step 102 includes the steps of: if the overlap result is that the RO time-frequency resource and the SBFD time-frequency resource partially overlap, determining that a data transmission operation corresponding to the target time-frequency resource is to prohibit transmitting a random access signal carried by the target RO if a symbol corresponding to the SBFD time-frequency resource is an uplink UL symbol or a flexible-F symbol, or to transmit a part of a random access signal corresponding to the overlapping resource in the random access signal in an overlapping resource that overlaps with the RO time-frequency resource in the SBFD time-frequency resource, or to determine that a data transmission operation corresponding to the target time-frequency resource is to prohibit transmitting the random access signal if a symbol corresponding to the SBFD time-frequency resource is a downlink DL symbol.

[0036] Figure 3 is a schematic diagram showing the overlap between SBFD time-frequency resources and target time-frequency resources. As shown in Figure 3, the RO time-frequency resources and the SBFD time-frequency resources are in a partially overlapping state. At this time, if the SBFD time-frequency resources are set on the UL symbol or the F symbol, two transmission methods are possible: a method 1 for regarding the RO as invalid and prohibiting the UE from transmitting a random access signal by the RO; and a method 2 for regarding the RO as valid and allowing the UE to transmit a part of a random access signal by the overlapping resource that overlaps with the RO time-frequency resource in the SBFD time-frequency resources, where the part of the random access signal is a part of the random access signal that can be transmitted by the overlapping resource. If the SBFD time-frequency resources are set on the DL symbol, the RO is invalid, and at this time, the UE is prohibited from transmitting a random access signal by the RO.

[0037] The above describes the case where only the RO channel overlaps with the SBFD time-frequency resource. However, other downlink channels / signals may exist other than the RO channel that overlap with the SBFD time-frequency resource, which may affect the transmission of the RO channel. The following describes the case where the RO channel and other channels overlap with the SBFD time-frequency resource.

[0038] In the following, an example will be described in which the downlink channel / signal is a synchronization signal block SSB.

[0039] Since the SSB is used for synchronization between the base station and the UE and transmits the MIB (Master Information Block) and SIB1 (Scheduling Information Block) containing the key information of the cell, the UE's accurate reception of the SSB is the basis for realizing normal communication. The UE needs to receive the SSB first, then receive the SIB1, and initiate random access based on the configuration information of the SBFD time-frequency resource extracted from the SIB1. However, in the description of the data transmission method according to the embodiment of the present invention, it is not necessary to consider the influence of the reception time of the SSB, because the reception of the SSB is periodic and there are a set of multiple SSBs in one period, and the technical solution of the present invention focuses on the scheduling / transmission of different channels / signals including the SSB after the UE analyzes the configuration information of the SBFD time-frequency resource.

[0040] In one example of the present invention, the target time-frequency resource mentioned in step 102 includes an RO time-frequency resource in which a target RO is located and an SSB time-frequency resource in which an SSB is located, the target RO is any RO among at least one RO configured for the target slot, and the RO time-frequency resource is located within the SBFD time-frequency resource.

[0041] In one example of the present invention, the determining step in step 102, if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the RO time-frequency resource do not overlap, determines that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the SSB in the SSB time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource if the UE is in a full-duplex TDD mode, or determines that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the SSB in the SSB time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource if the UE is in a half-duplex TDD mode. In a certain case, the step includes determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the SSB on the SSB time-frequency resource and transmit a random access signal carried by the target RO on the RO time-frequency resource when a condition that a time interval between the SSB and the target RO is greater than an uplink-downlink conversion time is met, and when the condition is not met, prohibit transmitting the random access signal on the RO time-frequency resource and receive the data carried by the SSB only on the SSB time-frequency resource.

[0042] For a UE that supports the SBFD mode, the UE can be further divided into two types: half-duplex UE, i.e., it can transmit or receive in the SBFD time-frequency resource, but can only transmit or receive at the same time, called HD UE, and full-duplex UE, i.e., it can simultaneously transmit and receive at the same time in the SBFD time-frequency resource, called FD UE. If a UE turns on the half-duplex mode, it can be a half-duplex UE, and if it turns on the full-duplex mode, it can be a full-duplex UE.

[0043] Figure 4 is a schematic diagram showing the overlap between SBFD time-frequency resource and target time-frequency resource. As shown in Figure 4, the target time-frequency resource includes RO time-frequency resource and SSB time-frequency resource, where RO time-frequency resource and SBFD time-frequency resource are in a completely overlapping state, that is, RO time-frequency resource is located in SBFD time-frequency resource. In this case, the overlapping situation between SBFD time-frequency resource and target time-frequency resource further includes the overlap between RO time-frequency resource and SSB time-frequency resource. At this time, regardless of whether SSB time-frequency resource and SBFD time-frequency resource overlap (referring to partial overlap) or not, if SSB time-frequency resource and RO time-frequency resource do not overlap, for FD UE, SSB and RO channel can transmit and receive normally, and neither is affected; for HD UE, the time interval between SSB and RO channel needs to meet the uplink downlink conversion time TRX, otherwise, the RO channel is considered invalid, and the RO channel is prohibited from transmitting RACH preamble, and only the data carried by SSB is received. The time interval may be the interval from the end of reception of the SSB to the start of transmission of the RO, or may be the interval from the start of transmission of the SSB to the end of reception of the RO, and a method of determining the time interval, which will be described later, is similar. The uplink-downlink conversion time is a time required for switching between uplink data transmission and downlink data reception, which is common in the art.

[0044] In one example of the present invention, the determining step in step 102 includes the steps of: if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the RO time-frequency resource partially overlap, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the SSB only on the SSB time-frequency resource and prohibit transmitting a random access signal carried by the target RO on the RO time-frequency resource, or to receive data carried by the SSB on the SSB time-frequency resource and transmit a part of the random access signal related to the remaining resources in the random access signal on the remaining resources in the RO time-frequency resource, where the remaining resources are time-frequency resources that do not overlap with the SSB time-frequency resource in the RO time-frequency resource.

[0045] As shown in Figure 5, the RO time-frequency resource is located within the SBFD time-frequency resource, and the SSB time-frequency resource and the RO time-frequency resource are partially overlapped, in this case, two transmission methods are possible: method 1, which regards the RO channel as invalid, prohibits the UE from sending a RACH preamble on the RO channel, and normally receives the data carried by the SSB; and method 2, which regards the RO channel as valid, transmits a part of the RACH preamble on the RO channel, and normally receives the data carried by the SSB. In method 2, specifically, the part of the RO time-frequency resource that does not overlap with the SSB time-frequency resource, i.e., the remaining resource, is used to transmit data related to the remaining part of the RACH preamble.

[0046] Since the reception of SSB is the basis of normal communication, the reception priority of SSB is higher than other downlink channels / signals, and when SSB and RO collide, the reception of SSB is guaranteed first. The base station does not need to consider the collision between SSB and SBFD time-frequency resources or RO channel, and can transmit SSB normally.

[0047] The above describes the case where the RO channel and the SSB overlap with the SSB time-frequency resource. Hereinafter, the above data transmission method will be described by taking the case where the RO channel and the physical downlink shared channel PDSCH coexist as an example.

[0048] In one embodiment of the present invention, the target time-frequency resource referred to in step 101 includes an RO time-frequency resource where a target random access channel opportunity RO is located and a PDSCH time-frequency resource where a target physical downlink shared channel PDSCH is located, the target RO is one of at least one RO configured for the target slot, and the RO time-frequency resource is located within the SBFD time-frequency resource.

[0049] In one embodiment of the present invention, the determining step performed in the above step 102 includes the steps of: if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDSCH time-frequency resource and the RO time-frequency resource do not overlap, when the UE is in a full-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDSCH in the PDSCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource; and if the UE is in a half-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDSCH in the PDSCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource. determining, when a condition that a time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met, that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDSCH on the PDSCH time-frequency resource and transmit a random access signal carried by the target RO on the RO time-frequency resource, and when the condition is not met, to transmit the random access signal only on the RO time-frequency resource and prohibit receiving the data carried by the target PDSCH on the PDSCH time-frequency resource.

[0050] In one example of the present invention, the determining step performed in the above step 102 includes the steps of: determining that if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap and the PDSCH time-frequency resource and the RO time-frequency resource do not overlap, when the UE is in a full-duplex TDD mode, a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDSCH in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDSCH time-frequency resource, and to transmit a random access signal carried by the target RO in the RO time-frequency resource; and determining that if the UE is in a half-duplex TDD mode, a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDSCH in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDSCH time-frequency resource, and to transmit a random access signal in the RO time-frequency resource in the RO time-frequency resource. determining, in a certain case, that a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDSCH in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDSCH time-frequency resource when a condition that a time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met, and transmit a random access signal carried by the target RO in the RO time-frequency resource; and when the condition is not met, transmit the random access signal only in the RO time-frequency resource, and prohibit receiving the data carried by the target PDSCH in the PDSCH time-frequency resource.

[0051] In one embodiment of the present invention, the determining step performed in the above step 102 includes the steps of: determining that if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap and the PDSCH time-frequency resource and the RO time-frequency resource partially overlap, when the UE is in a full-duplex TDD mode, a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDSCH in the PDSCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource; and determining that if the UE is in a half-duplex TDD mode, a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDSCH in the PDSCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource. determining that when a condition that a time interval between a PDSCH and the target RO is greater than an uplink-downlink conversion time is met, transmitting a random access signal carried by the target RO on the RO time-frequency resources and receiving some data related to the remaining resources in the data carried by the target PDSCH on the remaining resources that do not overlap with the RO time-frequency resources in the PDSCH time-frequency resources; or determining that when the condition is not met, transmitting the random access signal carried by the target RO only on the RO time-frequency resources and prohibiting receiving the data carried by the target PDSCH on the PDSCH time-frequency resources.

[0052] In one example of the present invention, the determining step performed in the above step 102 includes the steps of: determining, if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDSCH time-frequency resource and the RO time-frequency resource partially overlap, when the UE is in a full-duplex TDD mode, that the data transmission operation corresponding to the target time-frequency resource is to receive data related to the remaining resources in the data carried by the target PDSCH in the remaining resources that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource in the PDSCH time-frequency resource, and to transmit a random access signal carried by the target RO in the RO time-frequency resource; and determining, if the UE is in a half-duplex TDD mode, that the data transmission operation corresponding to the target time-frequency resource is to receive data related to the remaining resources in the data carried by the target PDSCH in the remaining resources that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource in the PDSCH time-frequency resource, and to transmit a random access signal carried by the target RO in the RO time-frequency resource. determining that a data transmission operation corresponding to a target time-frequency resource is to transmit a random access signal carried by the target RO on the RO time-frequency resource and receive some data related to the remaining resources in the data carried by the target PDSCH on the remaining resources in the PDSCH time-frequency resource that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource when a condition that a time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met; or to prohibit transmitting a random access signal carried by the target RO on the RO time-frequency resource and receiving the data carried by the target PDSCH on the PDSCH time-frequency resource when the condition is not met.

[0053] As shown in Figure 6, the RO time-frequency resource is located in the SBFD time-frequency resource, and the overlap result between the SBFD time-frequency resource and the target time-frequency resource has the following several different situation examples, among which: the first situation is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDSCH time-frequency resource and the RO time-frequency resource do not overlap; the second situation is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDSCH time-frequency resource and the RO time-frequency resource partially overlap; the third situation is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDSCH time-frequency resource and the RO time-frequency resource partially overlap; and the fourth situation is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDSCH time-frequency resource and the RO time-frequency resource do not overlap. This is merely an example and is not limiting.

[0054] For the first situation, as shown in FIG. 6, RO#1 and PDSCH1, in this case, if the UE is in full-duplex TDD mode, the PDSCH1 and RO#1 channels can be normally transmitted and received, and neither is affected. That is, the UE can normally transmit the random access signal carried by the RO#1 channel, and the base station can normally transmit the downlink data carried by the PDSCH1. If the UE is in half-duplex TTD mode, when the time interval between the RO#1 and PDSCH1 channels meets the uplink-downlink conversion time TRX, that is, the time interval is greater than the uplink-downlink conversion time TRX, the PDSCH1 and RO#1 channels can be normally transmitted and received, otherwise, only the RO channel transmits the RACH preamble, and the data carried by the PDSCH is prohibited from being received. As long as the UE is in half-duplex TTD mode, whether the UE or the base station needs to consider whether the time interval between the uplink-downlink time-frequency resources meets the condition of the uplink-downlink switching time, the same applies to other embodiments related to the following.

[0055] The base station also needs to consider whether the working mode of the UE is half-duplex or full-duplex. In the process of the UE accessing the network, the base station sends a message to the UE to inquire about the capability of the UE, and after receiving the message, the UE reports its capability to the base station, so that the base station can know whether the UE is a UE with SBFD capability, and can also know whether the UE is an FD UE or HD UE.

[0056] For the second situation, as shown in FIG. 6, there are two transmission means, namely, means 1 for canceling the reception of PDSCH2 and only transmitting RACH preamble on RO#2 channel, and means 2 for transmitting RACH preamble on RO#2 channel and receiving non-overlapping part of PDSCH2. In means 2, the reception of non-overlapping part of PDSCH2 specifically refers to receiving some data related to the remaining resources in the data carried by PDSCH2 by the remaining resources that do not overlap with RO time-frequency resources in the PDSCH time-frequency resources corresponding to PDSCH2. Here, when receiving the part of data, it is also necessary to consider whether the UE is HD UE or FD UE. If it is FD UE, it is normally received, and if it is HD UE, it is necessary to consider whether the time interval between PDSCH and RO satisfies uplink downlink conversion time TRX. In addition, since the downlink time-frequency resource for downlink channel transmission has changed, the base station needs to perform rate-matching on the coding data to adapt it to the new downlink time-frequency resource. Therefore, at this time, the part of the data received by the UE is actually the data obtained after the base station performs rate matching on the original data carried by the PDSCH.

[0057] As for the third situation, as shown in FIG. 6, there are two transmission means, namely, means 1 for canceling the reception of PDSCH3 and only transmitting RACH preamble on RO#2 channel, and means 2 for transmitting RACH preamble on RO#2 channel and receiving non-overlapping part of PDSCH3. In means 2, the reception of non-overlapping part of PDSCH3 specifically refers to receiving some data related to the remaining resources in the data carried by PDSCH3 by the remaining resources that do not overlap with SBFD time-frequency resources and RO time-frequency resources in the PDSCH time-frequency resources corresponding to PDSCH3. Here, when receiving the part of data, it is necessary to consider whether the UE is HD UE or FD UE, and if it is FD UE, it is normally received, and if it is HD UE, it is necessary to consider whether the time interval between PDSCH and RO satisfies uplink downlink conversion time TRX. In addition, because the downlink time-frequency resource for downlink channel transmission has changed, the base station needs to perform rate-matching on the data of the coding side to adapt to the new downlink time-frequency resource, so that the part of the data received by the UE is actually the data obtained after the base station performs rate matching on the original data carried by the PDSCH. The rate matching adopts a conventional technology, and is not described in the present invention.

[0058] For the fourth situation, as shown in FIG. 6, RO#1 and PDSCH3, in this case, FD UE can normally receive PDSCH3 and transmit RACH preamble on RO#1 channel, but when base station transmits PDSCH3, it needs to consider the overlap between PDSCH3 time-frequency resource and SBFD time-frequency resource, and transmits downlink data in the part that does not overlap with SBFD time-frequency resource of PDSCH3 after performing rate matching. HD UE normally transmits RACH preamble on RO#1 channel, and also needs to consider uplink-downlink conversion time TRX, and only receives downlink data carried by PDSCH3 when the uplink-downlink conversion time condition is met.

[0059] The above describes the case where the RO channel and the PDSCH both overlap with the SBFD time-frequency resource, and the PDSCH can be a repetition of the PDSCH, that is, the data transmission mechanism described above also applies to the repetition of the PDSCH.

[0060] The above data transmission method will be described below by taking as an example a case where the RO channel and a physical downlink control channel (PDCCH) overlap with the SBFD time-frequency resource.

[0061] In one embodiment of the present invention, the target time-frequency resource referred to in step 101 includes an RO time-frequency resource where a target random access channel opportunity RO is located and a PDCCH time-frequency resource where a target physical downlink control channel PDCCH is located, the target RO is one of at least one RO configured for the target slot, and the RO time-frequency resource is located within the SBFD time-frequency resource.

[0062] In one example of the present invention, the determining step performed in step 102 includes the steps of: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the PDCCH time-frequency resource and the RO time-frequency resource do not overlap, when the UE is in a full-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource; and if the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource. determining, in a certain case, that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH on the PDCCH time-frequency resource and transmit a random access signal carried by the target RO on the RO time-frequency resource when a condition that a time interval between the target PDCCH and the target RO is greater than an uplink-downlink conversion time is met, and to transmit the random access signal only on the RO time-frequency resource and prohibit receiving the data carried by the target PDCCH on the PDCCH time-frequency resource when the condition is not met.

[0063] In one embodiment of the present invention, the determining step performed in step 102 includes the steps of: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDCCH time-frequency resource and the RO time-frequency resource do not overlap, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource if the UE is in a full-duplex TDD mode; and if the UE is in a half-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource. determining that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH on the PDCCH time-frequency resource and transmit a random access signal carried by the target RO on the RO time-frequency resource when a condition that a time interval between the target PDCCH and the target RO is greater than an uplink-downlink conversion time is met, and to transmit the random access signal only on the RO time-frequency resource and prohibit receiving the data carried by the target PDCCH on the PDCCH time-frequency resource when the condition is not met.

[0064] In one embodiment of the present invention, the determining step performed in step 102 includes the steps of: determining that if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource partially overlap and the PDCCH time-frequency resource and the RO time-frequency resource do not overlap, when the UE is in a full-duplex TDD mode, a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDCCH in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDCCH time-frequency resource, and to transmit a random access signal carried by the target RO in the RO time-frequency resource; and determining that if the UE is in a half-duplex TDD mode, a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDCCH in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDCCH time-frequency resource, and to transmit a random access signal in the RO time-frequency resource in the half-duplex TDD mode. determining, when a condition that a time interval between the target PDCCH and the target RO is greater than an uplink-downlink conversion time is met, a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDCCH in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource, when the condition is not met, to transmit the random access signal only in the RO time-frequency resource and prohibit receiving the data carried by the target PDCCH in the PDCCH time-frequency resource.

[0065] In one embodiment of the present invention, the determining step performed in step 102 includes the steps of: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDCCH time-frequency resource and the RO time-frequency resource partially overlap, but the reception start point of the PDCCH is earlier than the transmission start point of the target RO, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource if the UE is in a full-duplex TDD mode; and determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and transmit a random access signal carried by the target RO in the RO time-frequency resource if the UE is in a half-duplex TDD mode. determining that the data transmission operation to be performed is to transmit a random access signal carried by the target RO on the RO time-frequency resource and receive some data related to the remaining resources in the data carried by the target PDCCH on the remaining resources that do not overlap with the RO time-frequency resource in the PDCCH time-frequency resource when a condition that a time interval between the target PDCCH and the target RO is greater than an uplink-downlink conversion time is met, or to transmit the random access signal carried by the target RO only on the RO time-frequency resource and prohibit receiving the data carried by the target PDCCH on the PDCCH time-frequency resource when the condition is not met.

[0066] In one embodiment of the present invention, the determining step performed in step 102 includes the steps of: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDCCH time-frequency resource and the RO time-frequency resource partially overlap, but a reception start point of the PDCCH is later than a transmission start point of the target RO, then, if the UE is in a full-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and to transmit a random access signal carried by the target RO in the RO time-frequency resource; and, if the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and to transmit a random access signal carried by the target RO in the RO time-frequency resource. determining that, when a condition that a time interval between the target PDCCH and the target RO is greater than an uplink-downlink conversion time is met, to transmit a random access signal carried by the target RO on the RO time-frequency resource and to receive some data related to the remaining resources in the data carried by the target PDCCH on the remaining resources in the PDCCH time-frequency resource that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource; or, when the condition is not met, to transmit the random access signal carried by the target RO only on the RO time-frequency resource and to prohibit receiving the data carried by the target PDCCH on the PDCCH time-frequency resource.

[0067] In one example of the present invention, the determining step performed in step 102 includes the step of determining that if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the PDCCH time-frequency resource and the RO time-frequency resource partially overlap, when there is no random access signal to be transmitted, the data transmission operation corresponding to the target time-frequency resource is to ignore the target RO, and to receive data carried by the target PDCCH in the PDCCH time-frequency resource, or to prohibit receiving data carried by the target PDCCH.

[0068] As shown in Figure 7, RO time-frequency resource is located in SBFD time-frequency resource, and the overlap result between SBFD time-frequency resource and target time-frequency resource has the following several different situation examples, among which: the first situation is that PDCCH time-frequency resource and SBFD time-frequency resource do not overlap, and PDCCH time-frequency resource and the RO time-frequency resource do not overlap; the second situation is that PDCCH time-frequency resource and SBFD time-frequency resource do not overlap, and PDCCH time-frequency resource and RO time-frequency resource partially overlap, but the reception start point of the PDCCH is earlier than the transmission start point of the target RO; the third situation is that PDCCH time-frequency resource and SBFD time-frequency resource do not overlap, and PDCCH time-frequency resource and RO time-frequency resource partially overlap, but the reception start point of the PDCCH is later than the transmission start point of the target RO. Of course, there may be other situations, which are merely examples and are not limited to these.

[0069] Regarding the first situation, as shown in FIG. 7, for RO#1 and PDCCH1, in this case, if the UE is in full-duplex TDD mode, the PDCCH1 and RO#1 channels can be normally transmitted and received, and neither is affected; if the UE is in half-duplex TTD mode, when the time interval between the RO#1 and PDCCH1 channels meets the uplink-downlink conversion time TRX, that is, the time interval is greater than the uplink-downlink conversion time TRX, the PDCCH1 and RO#1 channels can be normally transmitted and received; otherwise, only the RO#1 channel transmits a RACH preamble, and the reception of data carried by PDCCH1 is prohibited.

[0070] For the second situation, as shown in FIG. 7, there are three transmission means: a means 1 for canceling reception of PDCCH2 and transmitting only RACH preamble on RO#2 channel; a means 2 for transmitting RACH preamble on RO#2 channel and receiving non-overlapping part of PDCCH2; and a means 3 for receiving PDCCH2 normally and ignoring RO#2 or not receiving PDCCH2 when there is no RACH preamble to be transmitted. In the means 2, the reception of non-overlapping part of PDCCH2 specifically refers to receiving some data related to the remaining resources in the data carried by PDCCH2 by the remaining resources that do not overlap with RO time-frequency resources in the PDCCH time-frequency resources corresponding to PDCCH2. Here, when receiving the part of data, it is necessary to consider whether the UE is HD UE or FD UE. If it is FD UE, it is necessary to receive normally, and if it is HD UE, it is necessary to consider whether the time interval between PDCCH and RO satisfies uplink downlink conversion time TRX. In addition, since the downlink time-frequency resource for downlink channel transmission is changed, the base station needs to perform rate-matching on the coding data to adapt it to the new downlink time-frequency resource. Therefore, at this time, the part of the data received by the UE is actually the data obtained after the base station performs rate matching on the original data carried by the PDCCH.

[0071] For the third situation, as shown in FIG. 7, there are three transmission means: a means 1 for canceling reception of PDCCH3 and transmitting only RACH preamble on RO#2 channel; a means 2 for transmitting RACH preamble on RO#2 channel and receiving non-overlapping part of PDCCH3; and a means 3 for receiving PDCCH3 normally and ignoring RO#2 or not receiving PDCCH3 when there is no RACH preamble to be transmitted. In the means 2, the reception of non-overlapping part of PDCCH3 specifically refers to receiving some data related to the remaining resources in the data carried by PDCCH3 by the remaining resources that do not overlap with the RO time-frequency resources in the PDCCH time-frequency resources corresponding to PDCCH3. Here, when receiving the part of data, it is necessary to consider whether the UE is HD UE or FD UE. If it is FD UE, it is necessary to receive normally, and if it is HD UE, it is necessary to consider whether the time interval between PDCCH and RO satisfies uplink downlink conversion time TRX. In addition, since the downlink time-frequency resource for downlink channel transmission is changed, the base station needs to perform rate-matching on the coding data to adapt it to the new downlink time-frequency resource. Therefore, at this time, the part of the data received by the UE is actually the data obtained after the base station performs rate matching on the original data carried by the PDCCH.

[0072] In the above three example situations, the partial overlap between the SBFD time-frequency resource and the PDCCH time-frequency resource is not taken into consideration. If the SBFD time-frequency resource and the PDCCH time-frequency resource partially overlap, in addition to removing the overlap between the PDCCH and RO, it is also necessary to remove the overlap with the SBFD time-frequency resource.

[0073] The above describes the transmission mechanism of random access signals in the four-step random access procedure in SBFD mode, taking the RO channel, SSB, PDSCH, and PDCCH as examples.

[0074] In one embodiment of the present invention, the RO belongs to a dedicated RO group configured for SBFD mode, and / or the random access signal is a dedicated random access signal configured for SBFD mode or a normal random access signal defined by a protocol.

[0075] According to the 5G NR communication mechanism, there is a matching relationship between RO and SSB. For legacy UEs (Legacy UEs), the matching relationship between SSB and RO does not change depending on the SBFD setting because the SBFD setting cannot be identified. However, for UEs (SBFD UEs) that support SBFD mode, the matching relationship between SSB and RO changes depending on the SBFD setting. As can be seen from Figure 8, the SBFD time-frequency resource is located in the DL slot and is set to UL / Flexible. The upper half of Figure 8 corresponds to legacy UEs, and the lower half corresponds to SBFD UEs. Since a legacy UE does not recognize the SBFD setting in SIB1, the matching relationship between the SSB and RO of the legacy UE is that SSB#1 corresponds to RO#2 in slot#2, and SSB#2 corresponds to RO#3 in slot#2. Since an SBFD UE recognizes the SBFD setting in SIB1, the matching relationship between the SSB and RO of the SBFD UE is that SSB#1 corresponds to RO#1 in slot#1 and RO#3 in slot#2, and SSB#2 corresponds to RO#2 in slot#2. Therefore, the matching relationship between the SSB and RO between legacy UEs and SBFD UEs differs depending on the SBFD setting. In this case, if the UE selects RO#2 or RO#3 to transmit a RACH preamble, the base station does not know which UE, a legacy UE or an SBFD UE, sent the preamble, and therefore cannot determine the SSB corresponding to the RO, because the legacy UE and the SBFD UE use the same preamble set.

[0076] For this reason, the technical solution of the present invention proposes to configure a dedicated RACH preamble for the SBFD mode to identify the SBFD UE, and the configuration of the SBFD-dedicated RACH preamble carried by broadcast signaling (e.g., SIB1) is as follows: Since the SBFD UE selects and transmits the SBFD-dedicated RACH preamble based on the configuration, when the base station receives the preamble, it knows that it is the SBFD UE that needs to access, and determines the downlink beam for transmitting a random access response RAR based on the matching relationship between the SSB and RO configured for the SBFD UE. RACH-ConfigCommonForSBFD { SBFD-TotalNumberOfRA-Preambles SBFD-SSB-PerRACH-OccasionAndCB-PreamblesPerSSB}

[0077] Alternatively, distinction is made by RO, and SBFD UE uses an RO in an RO group configured for SBFD mode, while Legacy UE uses a normally configured RO, and the RO in the RO group dedicated to SSB and SBFD and the normally configured RO are respectively matched, as specifically shown in Figure 9. SBFD UE uses only RO#1 and RO#2 in Slot#1, while Legacy UE uses RO#1 and RO#2 in Slot#2, so that the matching relationship between SSB and RO is not erroneously identified by configuring SBFD.

[0078] The SBFD time-frequency resource configuration is sent to the UE by broadcast signaling. If the broadcast signaling does not include the SBFD time-frequency resource configuration, the SBFD resource for uplink random access may be dynamically configured in response to the random access triggered by the PDCCH order. The information indication content included in the DCI is shown in the table below, and mainly indicates the SBFD time-frequency resource and the PRACH resource in the SBFD time-frequency resource, as shown in Figure 10. [Table 1]

[0079] Two-step random access transmission method in SBFD mode The two-step random access procedure is a simplification of the four-step random access procedure. In step 1 of the four-step random access procedure, a random access signal is transmitted by the RO channel, but in step 1 of the two-step random access procedure, in addition to the MsgA RO channel, the MsgA PUSCH channel is also used to transmit uplink data, and the MsgA PUSCH channel is associated with the MsgA RO channel.

[0080] In the following, the data transmission mechanism in SBFD mode will be described in relation to the uplink / downlink time-frequency resources used in the two-step random access procedure.

[0081] In one embodiment of the present invention, the target time-frequency resource in step 101 includes an MsgA RO time-frequency resource in which a target MsgA random access channel opportunity RO for transmitting a random access message MsgA is located, and an MsgA PUSCH time-frequency resource in which a target MsgA physical uplink shared channel PUSCH related to the target MsgA RO is located. The target MsgA RO and the target MsgA PUSCH are as follows: the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, and the target MsgA RO related to the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, or the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, and the target MsgA RO related to the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, and the MsgA PUSCH and the MsgA RO correspond to different slots; or the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, and the target MsgA RO related to the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, and the MsgA PUSCH and the MsgA RO correspond to different slots. The target MsgA RO associated with the PUSCH is set to a slot allocated with SBFD time-frequency resources.

[0082] Configuring SBFD for broadcast signaling will affect the resource configuration of two-step random access, and there are currently three main situations: The first situation is that only the MsgA RO of two-step random access is configured in the SBFD resource, and the MsgA PUSCH is configured in the traditional UL slot, and the MsgA RO and the MsgA PUSCH are associated; this situation only applies to UEs that support SBFD mode, and is specifically shown in Figure 11.

[0083] There are two methods for allocating resources between MsgA RO and MsgA PUSCH. One is a method in which MsgA RO resources and MsgA PUSCH resources are allocated only to SBFD UEs. The other is a method in which MsgA RO resources are allocated only to SBFD users, but MsgA PUSCH resources can be shared by SBFD UEs and legacy UEs, and in order to distinguish between SBFD UEs and legacy UEs, an SBFD-specific RACH preamble is configured to identify SBFD UEs, or SBFD UEs can use only RO in SBFD resources.

[0084] The second situation is that a two-step random access MsgA RO is also configured on the SBFD resource, and a MsgA PUSCH channel is also configured, and the MsgA RO and the MsgA PUSCH are associated with each other. This situation only applies to SBFD UEs, and is specifically shown in FIG. 12.

[0085] The third situation is that only the MsgA PUSCH with two-step random access is configured on the SBFD resource, and the MsgA RO is in the traditional UL slot, and the MsgA RO and the MsgA PUSCH are associated with each other. This situation only applies to SBFD UEs, and is specifically shown in Figure 13.

[0086] There are two methods for resource allocation of MsgA RO and MsgA PUSCH. One is a method in which MsgA RO and MsgA PUSCH are allocated only to SBFD UEs. The other is a method in which MsgA PUSCH is allocated only to SBFD users, but MsgA RO resources can be shared by SBFD UEs and legacy UEs, and SBFD UEs can use a two-step RACH and legacy UEs can use a two-step RACH or a four-step RACH. In order to distinguish between SBFD UEs and legacy UEs, an SBFD-specific RACH preamble may be configured to identify SBFD UEs, or SBFD UEs may use only MsgA PUSCH and corresponding msgA RO in SBFD resources to perform two-step random access.

[0087] In the two-step random access transmission method in SBFD mode, the transmission mechanism of the MsgA RO channel is similar to that of the four-step random access transmission method, and the overlapping description is omitted here, and the following mainly describes the transmission of the MsgA PUSCH. However, due to the relationship between the MsgA PUSCH and the MsgA RO channel, when the MsgA RO channel is disabled, the MsgA PUSCH is also disabled, that is, data is not transmitted using the MsgA PUSCH. However, when the MsgA PUSCH is disabled, if the MsgA RO channel is enabled, the random access signal can be normally transmitted on the MsgA RO channel, and then the UE performs repeated transmission of the MsgA PUSCH. At this time, if the repeated transmission counter times out, the two-step random access can be switched to four-step random access.

[0088] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes an SSB time-frequency resource where a synchronization signal block SSB is located. The step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the MsgA PUSCH time-frequency resource do not overlap, when the UE is in a full duplex TDD mode, the data transmission operation corresponding to the target time-frequency resource is determined as receiving data carried by the SSB in the SSB time-frequency resource and determining the data transmission operation corresponding to the target MsgA PUSCH time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource, or, if the UE is in a half-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to receive the data carried by the SSB on the SSB time-frequency resource and transmit the data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource when a condition that a time interval between the SSB and the target RO is greater than an uplink-downlink conversion time is met, and prohibit transmitting the data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource and receive the data carried by the SSB only on the SSB time-frequency resource when the condition is not met.

[0089] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes an SSB time-frequency resource where a synchronization signal block SSB is located. In the step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource, if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the MsgA PUSCH time-frequency resource partially overlap, the data transmission operation corresponding to the target time-frequency resource prohibits transmitting data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource, or prohibits transmitting data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource. SSB The method includes determining that, in remaining resources that do not overlap with time-frequency resources, the target MsgA is to transmit a portion of data related to the remaining resources in the data carried by the PUSCH.

[0090] As shown in Figure 14, PUSCH time-frequency resource is located in SBFD time-frequency resource, the overlap result between SBFD time-frequency resource and target time-frequency resource can be divided into two situations, where the first situation is that SSB time-frequency resource and SBFD time-frequency resource overlap or do not overlap, and SSB time-frequency resource and PUSCH time-frequency resource do not overlap. For the first situation, if UE is in full-duplex TDD mode, SSB and MsgA PUSCH can be normally transmitted and received, and both are not affected; if UE is in half-duplex TTD mode, when the time interval between SSB and MsgA PUSCH meets uplink downlink conversion time TRX, that is, the time interval is greater than uplink downlink conversion time TRX, SSB and MsgA PUSCH can be normally transmitted and received; otherwise, MsgA PUSCH is invalid, and only SSB time-frequency resource receives data.

[0091] As shown in Figure 14, the second situation of the overlap result between the SBFD time-frequency resource and the target time-frequency resource is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the PUSCH time-frequency resource partially overlap. For the second situation, there are two transmission methods: means 1 in which the MsgA PUSCH is disabled and the UE cannot transmit data on the MsgA PUSCH; and means 2 in which the MsgA PUSCH is enabled and the UE can transmit some data on the MsgA PUSCH. In means 2, transmitting some data on the MsgA PUSCH specifically refers to using the remaining resources that do not overlap with the SSB time-frequency resources in the PUSCH time-frequency resource corresponding to the MsgA PUSCH to receive some data related to the remaining resources in the data carried by the MsgA PUSCH. In addition, since the uplink time-frequency resource for uplink channel transmission has changed, the UE needs to perform rate-matching on the coding data to adapt to the new uplink time-frequency resource. Therefore, at this time, the part of the data transmitted by the UE is actually the data obtained after performing rate matching on the original data carried by the MsgA PUSCH.

[0092] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes a PDCCH time-frequency resource where a target physical downlink control channel PDCCH is located. The step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes the steps of: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDCCH time-frequency resource and the MsgA PUSCH time-frequency resource do not overlap, when the UE is in a full-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the target PDCCH in the PDCCH time-frequency resource and to transmit data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource; and when the UE is in a half-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target MsgA PUSCH in the PDCCH time-frequency resource and to receive data carried by the target PDCCH in the PDCCH time-frequency resource and to transmit data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource. determining, when a condition that a time interval between the target PDCCH and the target MsgA PUSCH is greater than an uplink / downlink conversion time, to receive data carried by the target PDCCH on the PDCCH time-frequency resource and transmit data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource; and, when the condition is not satisfied, to transmit data carried by the target PDCCH only on the MsgA PUSCH time-frequency resource and prohibit receiving data carried by the target PDCCH on the PDCCH time-frequency resource.

[0093] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes a PDCCH time-frequency resource where a target physical downlink control channel PDCCH is located. The step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlapping result between the SBFD time-frequency resource and the target time-frequency resource includes: if the overlapping result is that the PDCCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDCCH time-frequency resource and the MsgA PUSCH time-frequency resource partially overlap but a reception start point of the PDCCH is later than a transmission start point of the target MsgA PUSCH, when the UE is in a full duplex TDD mode, the data transmission operation corresponding to the target time-frequency resource is determined by receiving data carried by the target PDCCH in the PDCCH time-frequency resource and transmitting data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource. and if the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource and receive some data related to the remaining resources in the data carried by the target PDCCH on remaining resources that do not overlap with the MsgA PUSCH time-frequency resource in the PDCCH time-frequency resource when a condition that a time interval between the target PDCCH and the target MsgA PUSCH is greater than an uplink-downlink conversion time is met, or to transmit data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource and prohibit receiving data carried by the target PDCCH on the PDCCH time-frequency resource when the condition is not met.

[0094] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes a PDCCH time-frequency resource on which a target physical downlink control channel PDCCH is located. The step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDCCH time-frequency resource and the MsgA PUSCH time-frequency resource do not overlap, when the UE is in a full duplex TDD mode, determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: receiving some data related to the remaining resources in data carried by the target PDCCH in the remaining resources not overlapping with the SBFD time-frequency resource in the PDCCH time-frequency resource; and when the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources in the data carried by the target PDCCH in remaining resources that do not overlap with the SBFD time-frequency resource in the PDCCH time-frequency resource when a condition that a time interval between the target PDCCH and the target MsgA PUSCH is greater than an uplink-downlink conversion time is met, and transmit the data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource; and when the condition is not met, transmit the data carried by the target MsgA PUSCH only in the MsgA PUSCH time-frequency resource and prohibit receiving the data carried by the target PDCCH in the PDCCH time-frequency resource.

[0095] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes a PDCCH time-frequency resource where a target physical downlink control channel PDCCH is located. The step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDCCH time-frequency resource and the MsgA PUSCH time-frequency resource partially overlap but a reception start point of the PDCCH is later than a transmission start point of the target MsgA PUSCH, when the UE is in a full duplex TDD mode, the data transmission operation corresponding to the target time-frequency resource is determined by receiving data carried by the target PDCCH in the PDCCH time-frequency resource and transmitting data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource. and if the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource and receive some data related to the remaining resources in the data carried by the target PDCCH on the remaining resources that do not overlap with either the SBFD time-frequency resource or the MsgA PUSCH time-frequency resource in the PDCCH time-frequency resource when a condition that a time interval between the target PDCCH and the target MsgA PUSCH is greater than an uplink-downlink conversion time is met; or, if the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource and receive some data related to the remaining resources in the data carried by the target PDCCH on the remaining resources that do not overlap with either the SBFD time-frequency resource or the MsgA PUSCH time-frequency resource in the PDCCH time-frequency resource when the condition is not met.

[0096] In one example of the present invention, the MsgA PUSCH time-frequency resource is located within the SBFD time-frequency resource, and the target time-frequency resource further includes a PDCCH time-frequency resource on which a target physical downlink control channel PDCCH is located, and the step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: determining that if the overlap result is that the PDCCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the PDCCH time-frequency resource and the MsgA PUSCH time-frequency resource partially overlap but a reception start point of the PDCCH is later than a transmission start point of the target MsgA PUSCH, when there is no random access signal to be transmitted, the data transmission operation corresponding to the target time-frequency resource is to ignore the target MsgA PUSCH and receive data carried by the target PDCCH in the PDCCH time-frequency resource.

[0097] As shown in FIG. 15 , the overlap result between the SBFD time-frequency resource and the target time-frequency resource can be divided into two situations, among which the first situation is that the PDCCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the PDCCH time-frequency resource and the PUSCH time-frequency resource do not overlap. Regarding the first situation, such as MsgA PUSCH1 / PUSCH2 and PDCCH1 in FIG. 15, in this case, if the UE is in full-duplex TDD mode, PDCCH1 and MsgA PUSCH1 / PUSCH2 can transmit and receive normally, and neither is affected; if the UE is in half-duplex TTD mode, when the time interval between MsgA PUSCH1 / PUSCH2 and PDCCH1 meets the uplink downlink conversion time TRX, that is, the time interval is greater than the uplink downlink conversion time TRX, PDCCH1 and MsgA PUSCH1 / PUSCH2 can transmit and receive normally; otherwise, data is transmitted only in MsgA PUSCH1 / PUSCH2, and the data carried by PDCCH1 is prohibited from being received.

[0098] As shown in Figure 15, the second situation of the overlap result between the SBFD time-frequency resource and the target time-frequency resource is that the PDCCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, the PDCCH time-frequency resource and the PUSCH time-frequency resource partially overlap, but the reception start point of the PDCCH is later than the transmission start point of the PUSCH. For the second situation, as shown in Figure 15 for PUSCH1 / PUSCH2 and PDCCH2, there are three transmission means: means 1 for canceling the reception of PDCCH2 and only transmitting data in MsgA PUSCH1 / PUSCH2, means 2 for transmitting data in MsgA PUSCH1 / PUSCH2 and receiving the non-overlapping part of PDCCH2, and means 3 for receiving PDCCH2 normally and ignoring MsgA PUSCH1 / PUSCH2 when the UE knows that it will not perform two-step RACH transmission. In the second means, the reception of the non-overlapping part of PDCCH2 specifically refers to receiving some data related to the remaining resources in the data carried by PDCCH2 by using the remaining resources that do not overlap with the PUSCH time-frequency resources in the PDCCH time-frequency resources corresponding to PDCCH2. Here, when receiving the part of the data, it is also necessary to consider whether the UE is HD UE or FD UE, and if it is FD UE, it is normally received, and if it is HD UE, it is necessary to consider whether the time interval between PDCCH2 and MsgA PUSCH1 / PUSCH2 satisfies the uplink downlink conversion time TRX. In addition, since the downlink time-frequency resources for performing downlink channel transmission have changed, the base station side needs to perform rate-matching on the data on the coding side to adapt to the new downlink time-frequency resources, and therefore, at this time, the part of the data received by the UE is actually the data obtained after the base station side performs rate matching on the original data carried by PDCCH2.

[0099] As shown in FIG. 16, the overlap result between the SBFD time-frequency resource and the target time-frequency resource can be divided into three situations, among which the first situation is that the PDSCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the PDSCH time-frequency resource and the PUSCH time-frequency resource do not overlap. Regarding the first situation, as shown in FIG. 16, for MsgA PUSCH1 / PUSCH2 and PDSCH1, in this case, if the UE is in full-duplex TDD mode, PDSCH1 and MsgA PUSCH1 / PUSCH2 can be normally transmitted and received, and neither is affected; if the UE is in half-duplex TTD mode, when the time interval between MsgA PUSCH1 / PUSCH2 and PDSCH1 meets the uplink downlink conversion time TRX, that is, the time interval is greater than the uplink downlink conversion time TRX, PDSCH1 and MsgA PUSCH1 / PUSCH2 can be normally transmitted and received; otherwise, data is only transmitted in MsgA PUSCH1 / PUSCH2, and the reception of data carried by PDSCH1 is prohibited.

[0100] As shown in Figure 16, the second situation of the overlap result between the SBFD time-frequency resource and the target time-frequency resource is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDSCH time-frequency resource and the PUSCH time-frequency resource partially overlap. For the second situation, as shown in Figure 16 for PUSCH1 / PUSCH2 and PDSCH2, there are two transmission means: a means 1 for canceling the reception of PDSCH2 and only transmitting data in MsgA PUSCH1 / PUSCH2, and a means 2 for transmitting data in MsgA PUSCH1 / PUSCH2 and receiving the non-overlapping part of PDSCH2. In the means 2, the reception of the non-overlapping part of PDSCH2 specifically refers to receiving some data related to the remaining resources in the data carried by PDSCH2 by using the remaining resources that do not overlap with the PUSCH time-frequency resources in the PDSCH time-frequency resources corresponding to PDSCH2. Here, when receiving the part of the data, it is also necessary to consider whether the UE is HD UE or FD UE, if it is FD UE, it will receive normally, if it is HD UE, it is necessary to consider whether the time interval between PDSCH2 and MsgA PUSCH1 / PUSCH2 satisfies the uplink downlink conversion time TRX. In addition, since the downlink time-frequency resource for downlink channel transmission has changed, the base station side needs to perform rate-matching on the data on the coding side to adapt to the new downlink time-frequency resource, therefore, at this time, the part of the data received by the UE is actually the data obtained after the base station side performs rate matching on the original data carried by PDSCH2.

[0101] As shown in Figure 16, the third situation of the overlap result between the SBFD time-frequency resource and the target time-frequency resource is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDSCH time-frequency resource and the PUSCH time-frequency resource partially overlap. For the third situation, as shown in Figure 16 for PUSCH1 / PUSCH2 and PDSCH3, there are two transmission means: a means 1 for canceling the reception of PDSCH3 and only transmitting data in MsgA PUSCH1 / PUSCH2, and a means 2 for transmitting data in MsgA PUSCH1 / PUSCH2 and receiving the non-overlapping part of PDSCH3. In the means 2, the reception of the non-overlapping part of PDSCH3 specifically refers to receiving some data related to the remaining resources in the data carried by PDSCH3 by using the remaining resources that do not overlap with the SBFD time-frequency resource in the PDSCH time-frequency resource corresponding to PDSCH3. Here, when receiving the part of the data, it is also necessary to consider whether the UE is HD UE or FD UE, if it is FD UE, it will receive normally, if it is HD UE, it is necessary to consider whether the time interval between PDSCH3 and MsgA PUSCH1 / PUSCH2 satisfies the uplink downlink conversion time TRX. In addition, since the downlink time-frequency resource for downlink channel transmission has changed, the base station side needs to perform rate-matching on the data on the coding side to adapt to the new downlink time-frequency resource, therefore, at this time, the part of the data received by the UE is actually the data obtained after the base station side performs rate matching on the original data carried by PDSCH3.

[0102] The SBFD time-frequency resource configuration is sent to the UE by broadcast signaling. If the broadcast signaling does not include the SBFD time-frequency resource configuration, the SBFD resource for uplink random access may be dynamically configured in response to the random access triggered by the PDCCH order. The information indication content included in the DCI is shown in the table below, and mainly indicates the SBFD time-frequency resource and the two-step PRACH resource in the SBFD time-frequency resource. [Table 2]

[0103] Corresponding to the data transmission method applied to the above-mentioned UE, in one example of the present invention, there is provided a data transmission method applied to a base station supporting a subband full duplex SBFD mode, characterized in that the data transmission method includes the steps of: determining an SBFD time-frequency resource corresponding to a target slot and a target time-frequency resource related to the target slot; determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource; and executing the determined data transmission operation in the target slot.

[0104] In one embodiment of the present invention, the target slot is an uplink UL slot, a downlink DL slot or a special slot, and the SBFD time-frequency resource occupies at least one symbol of the target slot in the time domain and occupies at least one physical resource block for each symbol in the frequency domain.

[0105] In one example of the present invention, the target time-frequency resource includes an RO time-frequency resource in which a target random access channel opportunity RO is located and an SSB time-frequency resource in which a synchronization signal block SSB is located, the target RO is any one of at least one RO set for the target slot, and the RO time-frequency resource is located within the SBFD time-frequency resource.

[0106] In one example of the present invention, the step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes the step of determining, if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the RO time-frequency resource partially overlap, that the data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the SSB only in the SSB time-frequency resource and prohibit performing detection of a random access signal in the RO time-frequency resource, or to transmit data carried by the SSB in the SSB time-frequency resource and receive a part of the random access signal related to the remaining resources in the random access signal carried by the target RO in the remaining resources in the RO time-frequency resource, where the remaining resources are time-frequency resources that do not overlap with the SSB time-frequency resource in the RO time-frequency resource,

[0107] In one example of the present invention, the step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the RO time-frequency resource do not overlap, when a UE that intends to receive data from the base station is in a full-duplex TDD mode, the data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the SSB in the SSB time-frequency resource and transmit random access data carried by the target RO in the RO time-frequency resource. or if the UE is in a half-duplex TDD mode, determining that a data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the SSB on the SSB time-frequency resource and receive a random access signal carried by the target RO on the RO time-frequency resource when a condition that a time interval between the SSB and the target RO is greater than an uplink-downlink conversion time is met, and prohibit performing detection of a random access signal on the RO time-frequency resource and transmit the data carried by the SSB only on the SSB time-frequency resource when the condition is not met.

[0108] In one example of the present invention, the target time-frequency resource includes an RO time-frequency resource in which a target random access channel opportunity RO is located and a PDSCH time-frequency resource in which a target physical downlink shared channel PDSCH is located, the target RO is one of at least one RO configured for the target slot, and the RO time-frequency resource is located within the SBFD time-frequency resource.

[0109] In one example of the present invention, the step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource includes: if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap, and the PDSCH time-frequency resource and the RO time-frequency resource do not overlap, when the UE that intends to receive data from the base station is in a full-duplex TDD mode, the data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target PDSCH in the PDSCH time-frequency resource and to receive a random access signal carried by the target RO in the RO time-frequency resource. or if the UE is in a half-duplex TDD mode, determining that the data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target PDSCH on the PDSCH time-frequency resource and receive a random access signal carried by the target RO on the RO time-frequency resource when a condition that a time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met, and to receive the random access signal only on the RO time-frequency resource and prohibit transmitting the data carried by the target PDSCH on the PDSCH time-frequency resource when the condition is not met.

[0110] In one example of the present invention, if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap, and the PDSCH time-frequency resource and the RO time-frequency resource do not overlap, when the UE that intends to receive data from the base station is in a full-duplex TDD mode, determine that the data transmission operation corresponding to the target time-frequency resource is to perform rate matching on the data carried by the target PDSCH, and transmit the data obtained after performing the rate matching in the remaining resources that do not overlap with the SBFD time-frequency resource in the PDSCH time-frequency resource, and receive the random access signal carried by the target RO in the RO time-frequency resource, when the UE is in a half-duplex TDD mode. In this case, determine that the data transmission operation corresponding to the target time-frequency resource is to perform rate matching on the data carried by the target PDSCH, and transmit the data obtained after performing the rate matching in the remaining resources in the PDSCH time-frequency resource that do not overlap with the SBFD time-frequency resource, and receive a random access signal carried by the target RO in the RO time-frequency resource; and when the condition is not met, receive the random access signal only in the RO time-frequency resource, and prohibit transmitting the data carried by the target PDSCH in the PDSCH time-frequency resource.

[0111] In one example of the present invention, the step of determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource comprises: if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource do not overlap and the PDSCH time-frequency resource and the RO time-frequency resource partially overlap, determining that the data transmission operation corresponding to the target time-frequency resource is to transmit data carried by the target PDSCH in the PDSCH time-frequency resource and receive a random access signal carried by the target RO in the RO time-frequency resource if the UE that intends to receive data from the base station is in a full-duplex TDD mode; or to receive a random access signal carried by the target RO in the RO time-frequency resource if the UE is in a half-duplex TDD mode. determining that the data transmission operation corresponding to the target time-frequency resource is to perform rate matching on data carried by the target PDSCH, and transmit data obtained after performing the rate matching in remaining resources in the PDSCH time-frequency resource that do not overlap with the RO time-frequency resource, and receive a random access signal carried by the target RO in the RO time-frequency resource, when a condition that a time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met; or to receive the random access signal only in the RO time-frequency resource, and prohibit transmitting the data carried by the target PDSCH in the PDSCH time-frequency resource, when the condition is not met.

[0112] In one example of the present invention, if the overlap result is that the PDSCH time-frequency resource and the SBFD time-frequency resource partially overlap and the PDSCH time-frequency resource and the RO time-frequency resource partially overlap, when the UE that intends to receive data from the base station is in a full-duplex TDD mode, determine that a data transmission operation corresponding to the target time-frequency resource is to perform rate matching on data carried by the target PDSCH, and transmit data obtained after performing the rate matching in the remaining resources in the PDSCH time-frequency resource that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource, and receive a random access signal carried by the target RO in the RO time-frequency resource; or when the UE is in a half-duplex TDD mode, determine that a data transmission operation corresponding to the target time-frequency resource is to perform rate matching on data carried by the target PDSCH, and transmit data obtained after performing the rate matching in the remaining resources in the PDSCH time-frequency resource that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource, and receive a random access signal carried by the target RO in the RO time-frequency resource. determine that the data transmission operation corresponding to a time-frequency resource is to perform rate matching on the data carried by the target PDSCH when a condition that a time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met, and transmit the data obtained after performing the rate matching in the remaining resources in the PDSCH time-frequency resource that do not overlap with either the RO time-frequency resource or the SBFD time-frequency resource, and receive a random access signal carried by the target RO in the RO time-frequency resource; or, when the condition is not met, receive a random access signal carried by the target RO in the RO time-frequency resource, and prohibit transmitting the data carried by the target PDSCH in the PDSCH time-frequency resource.

[0113] In one example of the present invention, the target time-frequency resource includes an RO time-frequency resource in which a target random access channel opportunity RO is located and a PDCCH time-frequency resource in which a target physical downlink control channel PDCCH is located, the target RO is one of at least one RO configured for the target slot, and the RO time-frequency resource is located within the SBFD time-frequency resource.

[0133] The data transmission method provided by the present invention has been described in detail above with reference to the specific examples. According to the technical solution provided by the present invention, the time-frequency domain resource of TDD SBFD can be used to perform uplink random access transmission without affecting the current 5G HD system, and the uplink access resource can be increased, thereby reducing the access delay, and the transmission criterion when the DL channel and the PRACH overlap is defined to determine the receiving and transmitting operations of the base station and the UE, reducing the blind detection of the base station and the UE, effectively increasing the uplink transmission opportunity, and improving the reliability of the uplink transmission.

[0135] The first determination module 1701 is used to determine an SBFD time-frequency resource corresponding to a target slot and a target time-frequency resource related to the target slot based on configuration information sent from a base station, the second determination module 1702 is used to determine a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource, and the execution module 1703 is used to execute the determined data transmission operation in the target slot.

[0136] In one embodiment of the present invention, the target slot is an uplink UL slot, a downlink DL slot or a special slot, and the SBFD time-frequency resource occupies at least one symbol of the target slot in the time domain and occupies at least one physical resource block for each symbol in the frequency domain.

[0141] In one example of the present invention, when determining a data transmission operation corresponding to the target time-frequency resource based on an overlap result between the SBFD time-frequency resource and the target time-frequency resource, the second determination module is specifically used to determine that if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and the SSB time-frequency resource and the RO time-frequency resource partially overlap, the data transmission operation corresponding to the target time-frequency resource is to receive data carried by the SSB only on the SSB time-frequency resource and prohibit transmitting a random access signal carried by the target RO on the RO time-frequency resource, or to receive data carried by the SSB on the SSB time-frequency resource and transmit a part of the random access signal related to the remaining resources in the random access signal on the remaining resources in the RO time-frequency resource, where the remaining resources are time-frequency resources that do not overlap with the SSB time-frequency resource in the RO time-frequency resource.
