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 typically operate in half-duplex (HD) mode. The TDD frame structure can be divided into DL (downlink) slots, S (special) slots, and UL (uplink) slots, of which S slots can be used for UL, DL, or GP (guard period). In current 5G commercial networks, to improve network throughput, many DL slots are generally allocated and relatively few UL slots are allocated, resulting in limited uplink transmission speeds and long uplink transmission delays.

[0003] FD (Full-Duplex) communication allows simultaneous transmission and reception, i.e., uplink and downlink data transmission. 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 INVENTION

[0011] The terms used in the embodiments of the present invention are merely for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention and in the claims, the singular forms "a," "the," and "the" are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in the present invention means to include any and all possible combinations of one or more of the associated listed items.

[0012] In 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 these terms are not limited to these terms. These terms are used only to distinguish between the same type of information. For example, first information may be referred to as second information, and similarly, second information may be referred to as first information, without departing from the scope of the present invention. Depending on the context, the word "if..." may be interpreted as "with...," "when...," or "in response to a determination."

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

[0014] In a TDD communication system, time domain resources are used to distinguish between the downlink and the 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, conventional 5G NR systems only consider allocation of time-frequency domain resources for physical channels in TDD HD mode, and do 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 the 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, ensuring that FD UEs can access the NR system smoothly and efficiently, and ensuring 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 the target time-frequency resource associated with 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 using Sub-Band Full Duplex (SBFD) method. Specifically, some SBFD time-frequency resources are set in the time-frequency resources in the current TDD mode, so that the SBFD time-frequency resources can transmit data in a direction different from that of 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 or dynamic manner. In the semi-static configuration, the base station may transmit the configuration information to the UE via system signaling (e.g., broadcast signaling or RRC signaling). In the dynamic configuration, the base station may transmit the configuration information via downlink control information (DCI). A UE that supports SBFD (referred to as SBFD UE) can identify the configuration of SBFD time-frequency resources from the received system signaling or DCI. A UE that does not support SBFD (referred to as Legacy UE) does not expect the base station to configure SBFD resources for itself. Even if the base station configures them, the Legacy UE directly ignores the configuration and performs network access and communication according to the legacy communication mode. For more information about SBFD, please refer to 3GPP TSG-RAN WG1 meeting documents R1-2203157 and R1-2203204.

[0022] In step 101, a UE supporting SBFD receives configuration information sent from a base station. Based on the configuration information, it can determine the configuration unit (e.g., slot or minislot) of the SBFD time-frequency resource, the slot to which it is configured, the configuration period, the application range (e.g., UL slot, DL slot, S slot, or a combination thereof), and other time-frequency resource-related configurations. The "target slot" refers to the UL slot, DL slot, or S slot to which the SBFD time-frequency resource is configured. Taking the UL slot as an example, the SBFD time-frequency resource may be configured for all or some of the UL symbols of the UL slot. In 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) and is the resource used for actual transmission. Within each BWP, the physical resource blocks are numbered according to a predefined indexing 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. The target slot may be understood as a currently focused slot or any slot for which an SBFD time-frequency resource is configured. The target time-frequency resource associated with the target slot is a time-frequency resource consistent with 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 (RACH), 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, etc. (These resources are not listed here.) Depending on the actual situation, some resources in the target time-frequency resource may be located in a different slot 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 associated with the target slot.

[0025] In the examples 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 refers to the overlap / non-overlap in the frequency domain, and does not take into account 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 occurs with the SBFD time-frequency resource. In addition, in the embodiments of the present invention, with regard to the overlap between the uplink time-frequency resource and the downlink time-frequency resource, the overlap may be 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 that they do not overlap in either the time 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 resources and the time-frequency resources set according to the conventional communication mechanism.

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

[0028] Above, a data transmission method according to an embodiment of the present invention has been described with reference to Figure 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 on the uplink channel. The random access procedure is a necessary process to establish a radio link between the UE and the network. Unless the random access procedure is completed, data exchange operations between the UE and the base station cannot be performed normally. The random access procedure allows the UE to achieve two basic functions: 1) to obtain uplink synchronization with the base station; if the uplink synchronization is lost, the UE can only transmit data on the PRACH; and 2) to request uplink resources (UL_GRANT).

[0030] Common random access procedures are divided into four-step random access and two-step random access. Hereinafter, channel transmission in SBFD mode will be described based on four-step random access and two-step random access. In the following description, the design of the data transmission mechanism in SBFD mode is mainly considered due to the conflict between the uplink / downlink time-frequency resources related to random access and the SBFD time-frequency resources, and the specific random access procedure will not be described in detail.

[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 the random access channel opportunity RO. The technical solution of the present invention establishes a policy for transmitting the RO channel in SBFD mode.

[0032] First, a case will be described in which 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 or more ROs may be set in one target slot, and a data transmission mechanism based on the SBFD mode will be described using any one of the ROs as the target RO.

[0033] Specifically, the determining step performed in step 102 includes the following steps: 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 the SBFD time-frequency resource and the target time-frequency resource. As shown in Figure 2, the RO time-frequency resource where the RO is located and the SBFD time-frequency resource are completely overlapped, that is, the RO time-frequency resource is located within the SBFD time-frequency resource. At this time, if the SBFD time-frequency resource is configured on the UL symbol or the F symbol, the RO is valid, and the UE can transmit a random access signal through the SBFD time-frequency resource (the part corresponding to the RO time-frequency resource). If the SBFD time-frequency resource is configured on the DL symbol, the RO is invalid, and the UE is prohibited from transmitting a random access signal through 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 the data transmission operation corresponding to the target time-frequency resource is to prohibit transmitting a random access signal carried by the target RO if the symbols corresponding to the SBFD time-frequency resource are uplink UL symbols or flexible-F symbols, or to transmit a part of the random access signal corresponding to the overlapping resources in the random access signal in the overlapping resources that overlap with the RO time-frequency resource in the SBFD time-frequency resource; or determining that the data transmission operation corresponding to the target time-frequency resource is to prohibit transmitting the random access signal if the symbols corresponding to the SBFD time-frequency resource are downlink DL symbols.

[0036] Figure 3 is a schematic diagram showing the overlap between the SBFD time-frequency resource and the target time-frequency resource. As shown in Figure 3, the RO time-frequency resource and the SBFD time-frequency resource are partially overlapping. In this case, if the SBFD time-frequency resource is configured on the UL symbol or the F symbol, two transmission methods are possible: (1) determining the RO as invalid and prohibiting the UE from transmitting a random access signal through the RO; and (2) determining the RO as valid and allowing the UE to transmit a portion of the random access signal through the overlapping resource of the SBFD time-frequency resource that overlaps with the RO time-frequency resource, where the portion of the random access signal is the portion of the random access signal that can be transmitted through the overlapping resource. If the SBFD time-frequency resource is configured on the DL symbol, the RO is invalid and prohibits the UE from transmitting a random access signal through the RO.

[0037] The above description is about the case where only the RO channel overlaps with the SBFD time-frequency resource. However, there may be other downlink channels / signals other than the RO channel that overlap with the SBFD time-frequency resource, which may affect the transmission of the RO channel. Below, we will describe the case where both the RO channel and other channels overlap with the SBFD time-frequency resource.

[0038] The following description will be given taking as an example a case where the downlink channel / signal is a synchronization signal block SSB.

[0039] 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), which contain cell key information. Therefore, accurate reception of the SSB by the UE is the basis for normal communication. The UE first needs to receive the SSB, then receive SIB1, and initiate random access based on the SBFD time-frequency resource configuration information extracted from SIB1. However, in describing the data transmission method according to the embodiment of the present invention, the influence of the SSB reception time does not need to be considered because the SSB reception is periodic and there are multiple sets of SSBs within one period. Therefore, the technical solution of the present invention focuses on scheduling / transmission of different channels / signals including SSBs after the UE analyzes the SBFD time-frequency resource configuration information.

[0040] In one example of the present invention, the target time-frequency resource mentioned in step 102 includes an RO time-frequency resource where a target RO is located and an SSB time-frequency resource where an SSB is located, where the target RO is any 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.

[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 In some cases, the method includes determining 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 when a condition that the time interval between the SSB and the target RO is greater than an uplink-downlink conversion time is met, and to prohibit transmitting the random access signal in the RO time-frequency resource and receive the data carried by the SSB only in the SSB time-frequency resource when the condition is not met.

[0042] For UEs that support the SBFD mode, the UE can be further divided into two types: half-duplex UEs, i.e., capable of transmitting or receiving on the SBFD time-frequency resources, but only capable of transmitting or receiving at the same time, called HD UEs, and full-duplex UEs, i.e., capable of simultaneously transmitting and receiving on the SBFD time-frequency resources at the same time, called FD UEs. If a UE turns on half-duplex mode, it can be a half-duplex UE, and if it turns on full-duplex mode, it can be a full-duplex UE.

[0043] Figure 4 is a schematic diagram showing the overlap between SBFD time-frequency resources and target time-frequency resources. As shown in Figure 4, the target time-frequency resources include RO time-frequency resources and SSB time-frequency resources, where the RO time-frequency resources and the SBFD time-frequency resources are in a completely overlapping state, i.e., the RO time-frequency resources are located within the SBFD time-frequency resources. In this case, the overlapping situation between the SBFD time-frequency resources and the target time-frequency resources also includes the overlap between the RO time-frequency resources and the SSB time-frequency resources. At this time, regardless of whether the SSB time-frequency resources and the SBFD time-frequency resources overlap (referring to partial overlap), as long as the SSB time-frequency resources and the RO time-frequency resources do not overlap, for FD UEs, the SSB and RO channels can transmit and receive normally and are not affected. For HD UEs, the time interval between the SSB and RO channels must satisfy the uplink / downlink conversion time TRX; otherwise, the RO channel is considered invalid and is prohibited from transmitting a RACH preamble on the RO channel, and only data carried by the SSB can be received. The time interval may be the interval from the end of SSB reception to the start of RO transmission, or the interval from the start of SSB transmission to the end of RO reception, and a method for determining the time interval, which will be described later, is similar. The uplink-downlink conversion time is the 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 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 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 partially overlap. In this case, two transmission methods are possible: (1) the RO channel is deemed invalid, the UE is prohibited from transmitting a RACH preamble on the RO channel, and the data carried by the SSB is successfully received; and (2) the RO channel is deemed valid, and a portion of the RACH preamble is transmitted on the RO channel, and the data carried by the SSB is successfully received. In method 2, specifically, the portion 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 portion of the RACH preamble.

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

[0047] The above description is based on the case where the RO channel and SSB overlap with the SSB time-frequency resource. Hereinafter, the above data transmission method will be described using 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, where the target RO is any 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 example 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 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 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 to transmit a random access signal carried by the target RO in the RO time-frequency resource. determining, in this case, 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 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, when the condition is not met, to transmit the random access signal only on the RO time-frequency resource and prohibit receiving 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 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 do not overlap, that 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, if the UE is in a half-duplex TDD mode, determining, in a certain case, that the 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 resources in the PDSCH time-frequency resource when a condition that the 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 example of the present invention, the determining step performed in the above step 102 includes 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 when 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, when a condition that a time interval between a PDSCH and the target RO is greater than an uplink-downlink conversion time, to transmit a random access signal carried by the target RO on the RO time-frequency resources and to receive some data related to the remaining resources of 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, when the condition is not met, to transmit the random access signal carried by the target RO only on the RO time-frequency resources and to prohibit 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 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, 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, if the UE is in a full-duplex TDD mode; 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 of the data carried by the target PDSCH on the remaining resources 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 satisfied; or to transmit a random access signal carried by the target RO on the RO time-frequency resource, and prohibit receiving the data carried by the target PDSCH on the PDSCH time-frequency resource, when the condition is not satisfied.

[0053] As shown in Figure 6, the RO time-frequency resource is located within the SBFD time-frequency resource, and the overlapping result between the SBFD time-frequency resource and the target time-frequency resource has several different example situations, 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. These are merely examples and are not limiting.

[0054] Regarding the first situation, as shown in FIG. 6 for RO#1 and PDSCH1, in this case, if the UE is in full-duplex TDD mode, the PDSCH1 and RO#1 channels can transmit and receive normally, and neither is affected. That is, the UE can transmit the random access signal carried by the RO#1 channel normally, and the base station can transmit the downlink data carried by the PDSCH1 normally. If the UE is in half-duplex TTD mode, if the time interval between the RO#1 and PDSCH1 channels satisfies the uplink-downlink conversion time TRX, i.e., if the time interval is greater than the uplink-downlink conversion time TRX, the PDSCH1 and RO#1 channels can transmit and receive normally. Otherwise, the RACH preamble is transmitted only on the RO channel, and the reception of the data carried by the PDSCH is prohibited. As long as the UE is in half-duplex TTD mode, both the UE and the base station need to consider whether the time interval between the uplink and downlink time-frequency resources satisfies the uplink-downlink switching time requirement, and this also applies to other embodiments described below.

[0055] The base station also needs to consider whether the UE's operating mode 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 UE's capabilities, and after receiving the message, the UE reports its capabilities to the base station, so that the base station can know whether the UE is a UE with SBFD capabilities, and can also know whether the UE is an FD UE or an HD UE.

[0056] For the second situation, as shown in Figure 6 for RO#2 and PDSCH2, there are two transmission means: means 1 for canceling the reception of PDSCH2 and transmitting only a RACH preamble on the RO#2 channel; and means 2 for transmitting a RACH preamble on the RO#2 channel while receiving the non-overlapping portion of PDSCH2. In means 2, receiving the non-overlapping portion of PDSCH2 specifically refers to receiving a portion of data related to the remaining resources of the data carried by PDSCH2 using the remaining resources that do not overlap with the RO time-frequency resources in the PDSCH time-frequency resources corresponding to PDSCH2. Here, when receiving the portion of data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If it is an FD UE, the data will be received normally. If it is an HD UE, it is necessary to consider whether the time interval between the PDSCH and RO satisfies the 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] For the third situation, as shown in Figure 6 for RO#2 and PDSCH3, there are two transmission means: Means 1 cancels reception of PDSCH3 and transmits only a RACH preamble on the RO#2 channel; and Means 2 transmits a RACH preamble on the RO#2 channel while receiving the non-overlapping portion of PDSCH3. In Means 2, receiving the non-overlapping portion of PDSCH3 specifically refers to receiving some data related to the remaining resources of the data carried by PDSCH3 using the remaining resources that do not overlap with the SBFD time-frequency resources and RO time-frequency resources in the PDSCH time-frequency resources corresponding to PDSCH3. Here, when receiving the partial data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If it is an FD UE, it will receive the data normally. If it is an HD UE, it is necessary to consider whether the time interval between the PDSCH and RO satisfies the 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 to the new downlink time-frequency resource, so 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. This rate matching adopts a conventional technology, and its description is omitted in this invention.

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

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

[0060] Hereinafter, the above data transmission method will be described taking as an example a case where the RO channel and the 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, where 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, 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 when the UE is in a full-duplex TDD mode; In some cases, determining that the 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 the 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 example of the present invention, the determining step performed in step 102 includes: 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, if so, 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 the time interval between the target PDCCH and the target RO is greater than an uplink-downlink conversion time is met; and, if the condition is not met, to transmit the random access signal only on the RO time-frequency resource and prohibit receiving data carried by the target PDCCH on the PDCCH time-frequency resource.

[0064] In one example of the present invention, the determining step performed in step 102 includes determining, 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, that if 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 if the UE is in a half-duplex TDD mode, determining, 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, 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 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. determining, if so, 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 the remaining resources that do not overlap with the SBFD time-frequency resource in the PDCCH time-frequency resource when a condition that the time interval between the target PDCCH 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, if 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 PDCCH in the PDCCH time-frequency resource.

[0065] In one example of the present invention, the determining step performed in step 102 includes: determining, 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, 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, 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 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 the data transmission operation to be performed is to transmit a random access signal carried by the target RO on the RO time-frequency resources and receive some data related to the remaining resources of the data carried by the target PDCCH on the remaining resources that do not overlap with the RO time-frequency resources in the PDCCH time-frequency resources, 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 resources and prohibit receiving the data carried by the target PDCCH on the PDCCH time-frequency resources, when the condition is not met.

[0066] In one example of the present invention, the determining step performed in step 102 includes 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 partially overlap, but a reception start point of the PDCCH is later than a transmission start point of the target RO, 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 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 when 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 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 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, to transmit a random access signal carried by the target RO on the RO time-frequency resources 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 resources that do not overlap with either the SBFD time-frequency resources or the RO time-frequency resources; or, when the condition is not met, to transmit the random access signal carried by the target RO only on the RO time-frequency resources and to prohibit receiving the data carried by the target PDCCH on the PDCCH time-frequency resources.

[0067] In one example of the present invention, the determining step performed in step 102 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 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 receive data carried by the target PDCCH in the PDCCH time-frequency resource, or prohibit receiving data carried by the target PDCCH.

[0068] As shown in Figure 7, the RO time-frequency resource is located within the SBFD time-frequency resource, and the overlapping result between the SBFD time-frequency resource and the target time-frequency resource has the following different example situations: the first situation 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; the second situation 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; and the third situation 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 later than the transmission start point of the target RO. Of course, there can be other situations, and these 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 transmit and receive normally, and neither will be 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 transmit and receive normally. 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 Figure 7 for RO#2 and PDCCH2, there are three transmission methods: means 1 for canceling reception of PDCCH2 and only transmitting a RACH preamble on the RO#2 channel; means 2 for transmitting a RACH preamble on the RO#2 channel while receiving the non-overlapping portion of PDCCH2; and means 3 for receiving PDCCH2 normally and ignoring RO#2 or not receiving PDCCH2 when there is no RACH preamble to be transmitted. In means 2, receiving the non-overlapping portion of PDCCH2 specifically refers to receiving some data related to the remaining resources of the data carried by PDCCH2 using the remaining resources that do not overlap with the RO time-frequency resources in the PDCCH time-frequency resources corresponding to PDCCH2. Here, when receiving the some data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If it is an FD UE, it will receive the data normally. If it is an HD UE, it is necessary to consider whether the time interval between the PDCCH and RO satisfies the 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 PDCCH.

[0071] For the third situation, as shown in FIG. 7 for RO#2 and PDCCH3, there are three transmission methods: (1) canceling reception of PDCCH3 and transmitting only a RACH preamble on the RO#2 channel; (2) transmitting a RACH preamble on the RO#2 channel while receiving the non-overlapping portion of PDCCH3; and (3) normally receiving PDCCH3 and ignoring RO#2 or not receiving PDCCH3 when there is no RACH preamble to be transmitted. In method 2, receiving the non-overlapping portion of PDCCH3 specifically refers to receiving a portion of data related to the remaining resources of the data carried by PDCCH3 using 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 portion of data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If the UE is an FD UE, normal reception is performed. If the UE is an HD UE, it is necessary to consider whether the time interval between the PDCCH and RO satisfies the 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 PDCCH.

[0072] The above three example situations do not take into account the partial overlap between the SBFD time-frequency resource and the PDCCH time-frequency resource. 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 specified by a protocol.

[0075] According to the 5G NR communication mechanism, there is a matching relationship between RO and SSB. For legacy UE (Legacy UE), the matching relationship between SSB and RO does not change depending on the SBFD setting because it cannot identify the SBFD setting. However, for UE that supports SBFD mode (SBFD UE), 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 within 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 legacy UEs do not recognize the SBFD setting in SIB1, the matching relationship between SSB and RO for legacy UEs is that SSB#1 corresponds to RO#2 in slot#2, and SSB#2 corresponds to RO#3 in slot#2. Since SBFD UEs recognize the SBFD setting in SIB1, the matching relationship between SSB and RO for SBFD UEs 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 SSB and RO for 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 legacy UE and SBFD UE use the same preamble set.

[0076] For this reason, the technical solution of the present invention proposes configuring a dedicated RACH preamble for the SBFD mode to identify SBFD UEs, 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 the SBFD UE needs to access, and determines a 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-ConfigCommonFor SBFD{ SBFD-TotalNumberOfRA-Preambles SBFD-SSB-PerRACH-OccasionAndCB-PreamblesPerSSB}

[0077] Alternatively, distinction is made by RO, with SBFD UEs using ROs in an RO group configured for SBFD mode, and Legacy UEs using ROs configured normally, and matching is performed between ROs in an RO group dedicated to SSB and SBFD and ROs configured normally, as specifically shown in Figure 9. SBFD UEs use only RO#1 and RO#2 in Slot#1, and Legacy UEs use RO#1 and RO#2 in Slot#2, thereby preventing misidentification of the matching relationship between SSB and ROs by configuring SBFD.

[0078] The SBFD time-frequency resource configuration is transmitted 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 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 simplified version of the four-step random access procedure. In step 1 of the four-step random access procedure, a random access signal is transmitted over the RO channel, but in step 1 of the two-step random access procedure, in addition to the MsgA RO channel, an 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 example of the present invention, the target time-frequency resource in step 101 includes an MsgA RO time-frequency resource where a target MsgA random access channel opportunity RO for transmitting a random access message MsgA is located, and an MsgA PUSCH time-frequency resource where a target MsgA physical uplink shared channel PUSCH associated with the target MsgA RO is located, wherein the target MsgA RO and the target MsgA PUSCH are configured such that the target MsgA PUSCH is set to a slot to which an SBFD time-frequency resource is allocated, and the target MsgA RO associated with 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 associated with 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 The target MsgA RO associated with the PUSCH is set to the slot allocated with the SBFD time-frequency resource.

[0082] Configuring SBFD for broadcast signaling affects the resource configuration for two-step random access, and there are currently three main scenarios: The first scenario is when only the MsgA RO for two-step random access is configured for the SBFD resource, and the MsgA PUSCH is configured in the conventional UL slot, and the MsgA RO and the MsgA PUSCH are associated. This scenario only applies to UEs that support SBFD mode, and is specifically shown in Figure 11.

[0083] There are two methods for allocating MsgA RO and MsgA PUSCH resources. 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 the MsgA RO for two-step random access is also configured on the SBFD resource, and the MsgA PUSCH channel is also configured, and the MsgA RO and the MsgA PUSCH are associated. This situation only applies to SBFD UEs, and is specifically shown in Figure 12.

[0085] The third situation is that only the two-step random access MsgA PUSCH is configured on the SBFD resource, and the MsgA RO is in the conventional 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 allocating resources for 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, while legacy UEs can use a two-step RACH or a four-step RACH. In addition, to distinguish between SBFD UEs and legacy UEs, an SBFD-specific RACH preamble can be configured to identify SBFD UEs, or SBFD UEs can use only MsgA PUSCH and the corresponding msgA RO in the SBFD resources, thereby performing 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. Therefore, the overlapping description will be 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 transmitted normally on the MsgA RO channel, and the UE then 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 the 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 by receiving data carried by the SSB in the SSB time-frequency resource and transmitting the data carried by the target MsgA PUSCH in the MsgA PUSCH 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 the 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, prohibiting the transmission of the data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource and receiving the data carried by the SSB only on the SSB time-frequency resource.

[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, a portion of data associated with the remaining resources in the data carried by the target MsgA PUSCH is to be transmitted.

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

[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: (1) the MsgA PUSCH is disabled and the UE cannot transmit data on the MsgA PUSCH; and (2) the MsgA PUSCH is enabled and the UE can transmit some data on the MsgA PUSCH. In (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 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 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 overlapping result between the SBFD time-frequency resource and the target time-frequency resource comprises: 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 does 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 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 the data carried by the target PDCCH on the PDCCH time-frequency resource and transmit the data carried by the target MsgA PUSCH on the MsgA PUSCH time-frequency resource; and, when the condition is not satisfied, to transmit the data carried by the target PDCCH only on the MsgA PUSCH time-frequency resource and prohibit receiving the 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 on which a target physical downlink control channel (PDCCH) is located. In 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, 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 to receive data carried by the target PDCCH in the PDCCH time-frequency resource and 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 MsgA PUSCH time-frequency resource and receive some data related to the remaining resources of the data carried by the target PDCCH in the remaining resources that do not overlap with the MsgA PUSCH time-frequency resource, when a condition that the time interval between the target PDCCH and the target MsgA PUSCH is greater than an uplink-downlink conversion time is met; or to transmit the data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource and prohibit receiving the data carried by the target PDCCH in 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 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 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 by receiving, in the remaining resources not overlapping with the SBFD time-frequency resource in the PDCCH time-frequency resource, some data related to the remaining resources in the data carried by the target PDCCH, and transmitting the target MsgA PUSCH time-frequency resource in the MsgA PUSCH time-frequency resource. determining, when the UE is in a half-duplex TDD mode, that a data transmission operation corresponding to the target time-frequency resource is to receive some data related to the remaining resources of data carried by the target PDCCH in the remaining resources that do not overlap with the SBFD time-frequency resources in the PDCCH time-frequency resources when a condition that the 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 resources when the condition is not met; and transmitting the data carried by the target PDCCH only in the MsgA PUSCH time-frequency resources and prohibiting reception of the data carried by the target PDCCH in the PDCCH time-frequency resources.

[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 on which a target physical downlink control channel (PDCCH) is located. In 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, if the overlapping 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 to be 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 transmit data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource and 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 either the SBFD time-frequency resource or the MsgA PUSCH 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, when the condition is not met, to transmit the data carried by the target MsgA PUSCH in the MsgA PUSCH time-frequency resource and prohibit receiving the data carried by the target PDCCH in the PDCCH time-frequency resource.

[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. 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: determining, when the overlapping result is that the PDCCH time-frequency resource and the SBFD time-frequency resource overlap or do not overlap, and that 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, that 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 if there is no random access signal to be transmitted.

[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 will be affected. If the UE is in half-duplex TTD mode, and the time interval between MsgA PUSCH1 / PUSCH2 and PDCCH1 satisfies the uplink-downlink conversion time TRX, that is, the time interval is greater than the uplink-downlink conversion time TRX, then PDCCH1 and MsgA PUSCH1 / PUSCH2 can transmit and receive normally. Otherwise, data is transmitted only on MsgA PUSCH1 / PUSCH2, and the reception of data carried by PDCCH1 is prohibited.

[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, and 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 cancels reception of PDCCH2 and transmits only data in MsgA PUSCH1 / PUSCH2; means 2 transmits data in MsgA PUSCH1 / PUSCH2 and receives the non-overlapping part of PDCCH2; and means 3 normally receives PDCCH2 and ignores MsgA PUSCH1 / PUSCH2 when the UE knows that two-step RACH transmission will not be performed. In the second means, receiving the non-overlapping portion of PDCCH2 specifically refers to receiving a portion of data related to the remaining resources of 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 portion of data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If it is an FD UE, the reception is normal. If it is an 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, because the downlink time-frequency resources for 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. Therefore, at this time, the portion of data received by the UE is actually data obtained after the base station side has performed 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 transmit and receive normally, and neither will be affected. If the UE is in half-duplex TTD mode, and the time interval between MsgA PUSCH1 / PUSCH2 and PDSCH1 satisfies 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 transmit and receive normally. Otherwise, data is transmitted only through 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: means 1 cancels reception of PDSCH2 and transmits only data in MsgA PUSCH1 / PUSCH2, and means 2 transmits data in MsgA PUSCH1 / PUSCH2 and receives the non-overlapping part of PDSCH2. In means 2, receiving the non-overlapping part of PDSCH2 specifically refers to using the remaining resources that do not overlap with the PUSCH time-frequency resource in the PDSCH time-frequency resource corresponding to PDSCH2 to receive some data related to the remaining resources in the data carried by PDSCH2. Here, when receiving the partial data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If it is an FD UE, the data will be received normally. If it is an 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 partial data received by the UE is actually data obtained after the base station side has performed 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 PUSCH1 / PUSCH2 and PDSCH3 in Figure 16, there are two transmission means: means 1 cancels reception of PDSCH3 and transmits only data in MsgA PUSCH1 / PUSCH2, and means 2 transmits data in MsgA PUSCH1 / PUSCH2 and receives the non-overlapping part of PDSCH3. In means 2, receiving the non-overlapping part of PDSCH3 specifically refers to using the remaining resources that do not overlap with the SBFD time-frequency resource in the PDSCH time-frequency resource corresponding to PDSCH3 to receive some data related to the remaining resources in the data carried by PDSCH3. Here, when receiving the partial data, it is also necessary to consider whether the UE is an HD UE or an FD UE. If it is an FD UE, the data will be received normally. If it is an 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 partial data received by the UE is actually data obtained after the base station side has performed rate-matching on the original data carried by PDSCH3.

[0102] The SBFD time-frequency resource configuration is transmitted 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 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 that supports 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 performing the determined data transmission operation in the target slot.

[0104] In one example 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: if the overlap result is that the SSB time-frequency resource and the SBFD time-frequency resource overlap or do not overlap and that 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 transmit data carried by the SSB only on the SSB time-frequency resource and prohibit performing detection of a random access signal on the RO time-frequency resource, or to transmit the data carried by the SSB on the SSB time-frequency resource and receive a part of a random access signal related to the remaining resources in the random access signal carried by the target RO 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.

[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 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 SSB in the SSB time-frequency resource and 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 the 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 the time interval between the SSB and the target RO is greater than an uplink-downlink conversion time is satisfied; and prohibiting performing detection of a random access signal on the RO time-frequency resource and transmitting the data carried by the SSB only on the SSB time-frequency resource when the condition is not satisfied.

[0108] In one example of the present invention, the target time-frequency resource 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 any 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 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 do not overlap, and if 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 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, when the condition is not met, 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.

[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, determine that if the UE intending to receive data from the base station is in a full-duplex TDD mode, 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 the SBFD time-frequency resource, and 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, 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 the SBFD time-frequency resource, and receive a random access signal carried by the target RO in the RO time-frequency resource. In this case, it is determined 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 when the condition that the time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met, transmit the data obtained after performing the rate matching on 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 on the RO time-frequency resource; and when the condition is not met, 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.

[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 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 the data obtained after performing the rate matching on the remaining resources in the PDSCH time-frequency resource that do not overlap with the RO time-frequency resource, when a condition that the time interval between the target PDSCH and the target RO is greater than an uplink-downlink conversion time is met, and receive the random access signal carried by the target RO on the RO time-frequency resource; or, when the condition is not met, 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.

[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, if the UE intending 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 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 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 if 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 the data obtained after performing the rate matching in the remaining resources that do not overlap with either the SBFD time-frequency resource or the RO time-frequency resource determine that the data transmission operation corresponding to the time-frequency resource is to perform rate matching on the data carried by the target PDSCH when the condition that the 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.

According to the technical solution provided by the present invention, uplink random access transmission can be performed using time-frequency domain resources of TDD SBFD without affecting the current 5G HD system, and uplink access resources can be increased, thereby reducing access delay. In addition, a transmission criterion when DL channel and PRACH overlap is defined to determine the reception and transmission behavior of the base station and UE, reducing blind detection of the base station and UE, effectively increasing uplink transmission opportunities, and improving the reliability of uplink transmission.

[0138] In one example of the present invention, when 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, the second determination module is specifically used to: if the overlapping result is that the RO time-frequency resource is located within the SBFD time-frequency resource, determine that the data transmission operation corresponding to the target time-frequency resource is to transmit a random access signal carried by the target RO on 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 determine 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.
