Description

Transmission method, terminal equipment and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission method, a terminal device, and a network side device.

Background

With the development of communication technology, future mobile communication systems, such as a fifth-Generation (5G) mobile communication system, need to adapt to more diversified scenarios and service requirements. The main scenes of the New Radio (NR) include enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mtc) (which may also be referred to as large-scale internet of things), Ultra-Reliable and Low-Latency Communication (URLLC), and these scenes provide requirements for the system such as high reliability, Low Latency, large bandwidth, wide coverage, and the like.

Currently, the random access procedure may include a 4-step random access procedure and a 2-step random access procedure. In 4-step random access (i.e., RACH), the UE first sends msg1 to the network, where the msg1 may include a Preamble; after detecting the Preamble, the network side may send msg2, where the msg2 may include a Random Access Response (RAR) message corresponding to the Preamble; after receiving the msg2, the UE sends msg3 according to the indication of the RAR; after receiving msg3, the network side sends msg4, and the msg4 contains a Contention Resolution identification (namely a Contention Resolution ID); and the UE receives the msg4, namely completing 4-step random access. In the 2-step RACH, the UE sends msgA to the network side, the network side sends msgB to the UE after receiving the msgA, and the UE completes 2-step random access after receiving the msgB.

However, in the prior art, there is no solution for how to transmit the Random Access message when there is an overlap between a time-frequency resource of a Physical Uplink Shared Channel (PUSCH) for transmitting the Random Access message and a time-frequency resource of a Physical Random Access Channel (RO).

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented, for example, in a sequence other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B and/or C, means that 7 cases are included that include a alone, B alone, C alone, and both a and B, B and C, a and C, and A, B and C.

For ease of understanding, some of the matters involved in the embodiments of the present invention are described below:

PRACH opportunities (PRACH opportunities, RO):

in NR, a network side may configure a PRACH Transmission opportunity (i.e., PRACH Transmission opportunity) or a PRACH opportunity (i.e., PRACH mission opportunity) where multiple Frequency Division Multiplexing (FDM) exists at a Time point (Time Instance, which is a Time period required for transmitting one PRACH resource, and may also be referred to as a Time domain position for transmitting the PRACH). The number of ROs that can be FDM on one Time Instance may be: {1,2,4,8}.

The random access preamble can be transmitted only on the time domain resource configured by the parameter PRACHConfigurationIndex, and the random access preamble can be transmitted only on the frequency domain resource configured by the parameter PRACH-FDM, specifically, the PRACH frequency domain resource n_RAE {0, 1., M-1}, where M equals the higher layer parameter prach-FDM. During Initial access, the PRACH frequency domain resources start ascending numbering from an RO resource with the lowest frequency in an Initial activated Uplink Bandwidth Part (i.e., Active Uplink Bandwidth Part), otherwise, the PRACH frequency domain resources start ascending numbering from an RO resource with the lowest frequency in the activated Uplink Bandwidth Part (i.e., Active Uplink Bandwidth Part).

In NR, there is an association between an RO and an actually transmitted synchronization Signal Block (SSB or SS Block for short) or a Physical Broadcast Channel Block (PBCH Block). One RO may be associated with multiple SSBs, and the number of SSBs associated with one RO may be: {1/8,1/4,1/2,1,2,4,8, 16}. For a non-contention random access procedure, the RO and a Channel State Information Reference Signal (CSI-RS) may also have an association relationship.

The number of FDM ROs on a Time Instance is 8, and the number of SSBs actually transmitted is 4, for example, the corresponding SSBs are SSB #0, SSB #1, SSB #2, and SSB #3, and each SSB is associated with 2 ROs. If the UE transmits the PRACH on the RO corresponding to the SSB0, the UE selects one RO from RO #0 and RO #1 for PRACH transmission.

And (3) unauthorized frequency band:

in future communication systems, an Unlicensed Band (i.e., Unlicensed Band) may be used as a supplement to a Licensed Band (i.e., Licensed Band) to help an operator expand the capacity of a service. In order to maintain compliance with NR deployment and maximize NR-based unlicensed access as much as possible, unlicensed bands may operate in the 5GHz, 37GHz, and 60GHz bands. The large bandwidth of the unlicensed band (80MHz or 100MHz) can reduce the implementation complexity of the base station and the UE. Since the unlicensed frequency band is shared by multiple technologies (RATs), such as WiFi, radar, Long Term Evolution licensed Assisted Access (LTE-LAA), etc., the unlicensed frequency band generally needs to conform to some rules (i.e. regulations) when being used, so as to ensure that all devices can fairly use the resource, for example, rules such as Listen Before Talk (LBT), Maximum Channel Occupancy Time (MCOT), etc. When a transmission node needs to send information, LBT needs to be performed first, power Detection (ED) is performed on surrounding nodes, and when the detected power is lower than a threshold, a channel is considered to be empty (i.e., Idle), and the transmission node can send the information. Otherwise, the channel is considered to be busy, and the transmitting node cannot transmit. The transmission node may be a base station, a UE, a WiFi AP, etc. After a transmitting node starts transmitting, its occupied channel time (i.e., COT) cannot exceed the MCOT.

In addition, according to the Occupied Channel Bandwidth (OCB) rule (i.e., Regulation), in the unlicensed band, the transmission node occupies at least 70% (60GHz) or 80% (5GHz) of the Bandwidth of the entire frequency band at each transmission.

Listen before talk:

the types of LBT commonly used (i.e., Category) can be classified as type 1 (i.e., Category1), type 2 (i.e., Category2), and type 4 (i.e., Category 4). Category1 LBT is no LBT, i.e. no LBT or Immediate Transmission (Immediate Transmission) by the sending node. The Category2 LBT is a one-shot LBT, that is, the node performs LBT once before transmission, and transmits if the channel is empty, and does not transmit if the channel is busy. Category4 LBT is a Back-off (Back-off) based channel sensing mechanism, which performs Back-off when a transmitting node senses that a channel is busy, and continues sensing until sensing that the channel is empty.

The embodiment of the invention provides a transmission method. Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal Device 11 and a network-side Device 12, where the terminal Device 11 may be a user-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that a specific type of the terminal Device 11 is not limited in the embodiment of the present invention. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, gNB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, or the network side device 12 may be an Access Point (AP); the base station may also be a network node composed of a Central Unit (CU) together with a plurality of TRPs whose management is and is controlled. It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.

The embodiment of the invention provides a transmission method which is applied to terminal equipment. Referring to fig. 2, fig. 2 is a flowchart of a transmission method according to an embodiment of the present invention, and as shown in fig. 2, the transmission method includes the following steps:

step 201, under the condition that the time frequency resource of a target physical uplink shared channel opportunity (PO) and the time frequency resource of a target physical random access channel opportunity (RO) are overlapped, performing rate matching or punching on a Physical Uplink Shared Channel (PUSCH) of a random access message corresponding to the target PO according to the time frequency resource of the target RO.

In this embodiment, the target PO (i.e., PUSCH occupancy) may be any PO for transmitting a random access message, and the target RO (i.e., PRACH occupancy) may also be any RO for transmitting a random access message.

It should be noted that the Random Access message in the embodiment of the present invention may be carried in at least one of a Physical Random Access CHannel (PRACH) and a Physical Uplink Shared CHannel (PUSCH), that is: the random access message is carried in PRACH; or, the random access message is carried on the PUSCH; or, the random access message is carried on the PRACH and the PUSCH.

In the process of 2-step random access, the random access message sent by the terminal device is carried on the PRACH and the PUSCH. Wherein, under the condition that the random access message is carried on the PRACH and the PUSCH, a part of the content of the random access message, for example, the Preamble code, may be transmitted through the PRACH; another part of the content of the random access message, for example, the terminal device identity or the cell radio network temporary identity (i.e., TC-RNTI), etc., may be transmitted through the PUSCH.

In the case where the above random access message is carried on at least one of the PRACH and the PUSCH, accordingly, the transmission opportunity of the random access message includes at least one of the PRACH occupancy (i.e., RO) and the PUSCH occupancy (i.e., PO). Namely: if the random access message is borne on the PRACH, the transmission opportunity of the random access message comprises the PRACH Occasion; or, if the random access message is carried on the PUSCH, the transmission opportunity of the random access message includes PUSCH occupancy; or, if the random access message is carried on the PRACH and the PUSCH, the transmission opportunity of the random access message includes PRACH occupancy and PUSCH occupancy.

In the embodiment of the present invention, before sending the PUSCH of the random access message (e.g., MsgA), the terminal device may acquire PUSCH occupancy for the terminal device to transmit the PUSCH. The PUSCH transmission opportunity may be preconfigured by the network device and may include one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols.

Optionally, the PUSCH occupancy may be associated with the PRACH occupancy, specifically, one PUSCH occupancy may be associated with one PRACH occupancy, one PUSCH occupancy may be associated with multiple PRACH occussions, multiple PUSCH occussions may be associated with one PRACH occupancy, or multiple PUSCH occussions are associated with multiple PRACH occussions, without limitation.

Optionally, the overlapping of the time-frequency resource of the target PO and the time-frequency resource of the target RO may include overlapping of a part of the time-frequency resource of the target PO and a part of or all of the time-frequency resources of the target RO. It should be noted that the target RO may include one or at least two ROs, that is, the target PO may overlap with one or at least two ROs.

For example, referring to fig. 3a or fig. 3b, there is an overlap between the time-frequency resource of PO1 and the time-frequency resource of RO2, and an overlap between the time-frequency resource of PO2 and the time-frequency resource of RO 3. For another example, referring to fig. 3c, there is an overlap of the time-frequency resource of PO1 with the time-frequency resource of RO3 and the time-frequency resource of RO 4.

Optionally, the time-frequency resource of the PO configured by the network side for random access message transmission partially overlaps with the time-frequency resource of the at least one RO.

It should be noted that, the overlapping of the time-frequency resource of the target PO and the time-frequency resource of the target RO may include overlapping of the time-domain resource of the target PO and the time-domain resource of the target RO in a time domain, overlapping of the time-domain resource of the target PO and the time-domain resource of the target RO in a frequency domain, or overlapping of the time-domain resource of the target PO and the time-domain resource of the target RO in both the time domain and the frequency domain.

In this step 201, under the condition that the time frequency resources of the target PO and the time frequency resources of the target RO are overlapped, rate matching may be performed on the PUSCH of the random access message corresponding to the target PO according to the time frequency resources of the target RO, for example, the PUSCH of the random access message corresponding to the target PO may be mapped to the time frequency resources where the target PO and the target RO are not overlapped in a rate matching manner, and the time frequency overlapping the time frequency resources of the target RO is not resource mapped; the PUSCH of the random access message corresponding to the target PO may also be punctured according to the time frequency resource of the target RO, for example, the PUSCH of the random access message corresponding to the target PO may be mapped to all time frequency resources of the target PO, and the PUSCH may be punctured on the time frequency resource where the target PO and the target RO overlap.

Optionally, if the time-frequency resource of the target PO and the time-frequency resource of the target RO overlap in the time domain, the PUSCH may be punctured in the time-domain resource where the target PO and the target RO overlap; if the time-frequency resource of the target PO and the time-frequency resource of the target RO overlap in the time domain and the frequency domain, the PUSCH may be punctured in the time-frequency resource and the frequency-frequency resource where the target PO and the target RO overlap.

Optionally, in a case that the time-frequency resources of the target PO and the time-frequency resources of the at least two ROs overlap, the target RO may include one or more of the at least two ROs. For example, referring to fig. 3c, the time frequency resource of PO1, the time frequency resource of RO3, and the time frequency resource of RO4 are overlapped, and the PUSCH of the random access message corresponding to PO1 may be rate-matched or punctured according to the time frequency resource of RO3, the PUSCH of the random access message corresponding to PO1 may be rate-matched or punctured according to the time frequency resource of RO4, or the PUSCH of the random access message corresponding to PO1 may be rate-matched or punctured according to the time frequency resource of RO3 and the time frequency resource of RO 4.

Optionally, the frequency domain resource of the target PO and the frequency domain resource of the target RO may both be located in a licensed frequency band or an unlicensed frequency band. The random access message may be msgA of a 2-step random access message.

In practical applications, when the frequency domain resources of the ROs and the frequency domain resources of the POs used for random access message transmission are both located in the unlicensed frequency band, the terminal device may perform LBT on the channel before each RO or PO starts, and if the channel sensing result is that the channel is idle, the UE may send a random access message, for example, msgA of the 2-step random access procedure. For example, referring to fig. 3a, if it is sensed that the channel is idle before the RO1, the UE may transmit msgA at the RO1 and PO1, and since there is an overlap between the time-frequency resource of the PO1 and the time-frequency resource of the RO2, the UE may perform rate matching or puncturing on the msgA PUSCH according to the time-frequency resource of the RO 2.

Step 202, a target PUSCH is sent on the target PO, wherein the target PUSCH is a PUSCH subjected to rate matching or puncturing.

In this embodiment, after performing rate matching or puncturing on the PUSCH of the random access message corresponding to the target PO according to the time-frequency resource of the target RO, the PUSCH after rate matching or puncturing may be sent on the target PO, which provides a way to transmit the random access message when there is overlap between the time-domain resource of the PO used for random access message transmission and the time-domain resource of the RO, and may further reduce the influence on the information transmission performance due to resource overlap. In addition, since the PUSCH after rate matching or puncturing is transmitted on the target PO, the influence on the target RO can be reduced, and thus the reduction of the RO due to resource overlapping can be reduced.

Optionally, the time-frequency resource of the target PUSCH and the time-frequency resource of the target RO are not overlapped.

Optionally, the frequency domain resources of the target PO are distributed in the uplink transmission bandwidth in a discontinuous manner.

In this embodiment, the frequency domain resources of each PO configured by the network side for random access message transmission may be distributed in the uplink transmission bandwidth in a discontinuous manner. The uplink transmission bandwidth may be located in a licensed frequency band or an unlicensed frequency band. Specifically, the uplink transmission Bandwidth may be a currently activated uplink Bandwidth Part (i.e., active UL Bandwidth Part), or an initial uplink Bandwidth Part (i.e., initial UL BWP), or a frequency domain resource configured by the network side for transmitting the random access message.

Optionally, in a case where the random access process is initiated in the unlicensed frequency band, the uplink transmission bandwidth may be an unlicensed frequency band bandwidth, that is, frequency domain resources of each PO for transmitting the random access message may be distributed in the licensed frequency band bandwidth in a discontinuous manner.

In this embodiment, the frequency domain resources of the target PO are distributed in the uplink transmission bandwidth in a discontinuous manner, and it can be ensured that the transmission of the random access message satisfies the OCB rule under the condition that the random access message is configured to be transmitted on continuous time frequency resources.

Optionally, the frequency domain resources of the target PO are distributed in the uplink transmission bandwidth in an interleaving manner.

In this embodiment, the frequency domain resources of at least two POs with the same time domain resource may be distributed in the uplink transmission bandwidth in an interleaving manner. For example, referring to fig. 3c, the time domain resources of PO1 and PO2 are the same, and PO1 and PO2 are distributed in an interleaved manner over the unlicensed band bandwidth in the frequency domain.

Optionally, at least two ROs used for the random access message transmission are consecutive in a time domain, where the at least two ROs include the target RO.

In this embodiment, at least two ROs for transmitting the random access message may be configured by a network side, and the at least two ROs are consecutive in a time domain. The target RO may be any of the at least two ROs. For example, referring to fig. 3a or 3b, the configured 5 ROs (i.e., RO1 through RO5) are consecutive in the time domain.

Optionally, the RO for the random access message transmission and the at least one PO for the random access message transmission are consecutive in a time domain.

In this embodiment, the network side may configure that the RO for the random access message transmission and the at least one PO for the random access message transmission are consecutive in a time domain. For example, referring to fig. 3a or fig. 3b, RO1 and PO1 are contiguous in the time domain,RO2and PO2 are contiguous in the time domain. For another example, referring to fig. 3c, RO1 is temporally contiguous with PO1 and PO2, respectively, and RO2 is also temporally contiguous with PO1 and PO2, respectively.

Optionally, a first RO is associated with at least one first PO, the first RO is an RO used for the random access message transmission, the first PO is a PO used for the random access message transmission, and the first PO is consecutive to the first RO in a time domain.

In this embodiment, the network side may configure association of ROs and POs that are consecutive in a time domain, so that the PRACH and the PUSCH of the random access message may be transmitted through the associated ROs and POs, respectively.

For example, referring to fig. 3a, RO1 is associated with PO1, if the terminal device senses that the channel is free before RO1, the terminal device may send PRACH and PUSCH of the random access message at RO1 and PO1, respectively.

Optionally, in practical applications, the terminal device may receive, from the network-side device, configuration information for a random access procedure (e.g., a 2-step random access procedure), where the configuration information may be used to indicate time-frequency resources of at least two ROs and time-frequency resources of at least two POs. Optionally, the time-frequency resources of the at least two ROs may be continuous in a time domain. Alternatively, an RO of the at least two ROs may be temporally continuous with at least one PO of the at least two POs. Optionally, the time-frequency resources of the POs of the at least two POs may overlap with the time-frequency resources of at least one RO of the at least two ROs. Alternatively, an RO of the at least two ROs may be associated with at least one PO thereof that is consecutive in time. Optionally, the frequency domain resources of the POs of the at least two POs are distributed in the uplink transmission bandwidth in a discontinuous manner.

Optionally, the performing, according to the time-frequency resource of the target RO, rate matching or puncturing on the PUSCH of the random access message corresponding to the target PO may include:

and under the condition that the target RO is the effective RO, performing rate matching or punching on the PUSCH of the random access message corresponding to the target PO according to the time-frequency resource of the target RO.

In this embodiment, when the target RO is an effective RO, for example, when the target RO has an associated PO, the PUSCH of the random access message corresponding to the target PO may be rate-matched or punctured according to the time-frequency resource of the target RO, otherwise, the PUSCH of the random access message corresponding to the target PO may not be rate-matched or punctured, which not only can ensure data transmission, but also can reduce the degradation of information transmission performance caused by the overlapping of the time-frequency resource of the RO and the time-frequency resource of the PO.

Optionally, the method may further include:

and sending the PUSCH of the random access message corresponding to the target PO on the target PO under the condition that the target RO is invalid.

In this embodiment, when the target RO is an invalid RO, for example, when the target RO does not have an associated PO, the PUSCH of the random access message corresponding to the target PO may be directly sent on the target PO, and it is not necessary to perform rate matching or puncturing on the PUSCH of the random access message corresponding to the target PO, which may not only improve data transmission efficiency, but also improve data transmission integrity.

Optionally, the condition for determining that the target RO is a valid RO includes: the target RO has an associated PO;

and/or

The condition for deciding that the target RO is an invalid RO includes: the target RO has no associated PO.

In this embodiment, under the condition that a target RO has an associated PO, rate matching or puncturing may be performed on a PUSCH of a random access message corresponding to the target PO according to a time-frequency resource of the target RO; and under the condition that the target RO has no associated PO, directly sending the PUSCH of the random access message corresponding to the target PO on the target PO.

The embodiment of the invention provides a transmission method which is applied to network side equipment. Referring to fig. 4, fig. 4 is a flowchart of a transmission method according to an embodiment of the present invention, and as shown in fig. 4, the transmission method includes the following steps:

step 401, receiving a target PUSCH on a target physical uplink shared channel opportunity (PO);

In this embodiment, the target PO may be any PO for transmitting a random access message, and the target RO may also be any RO for transmitting a random access message.

The target PUSCH may be a PUSCH obtained by performing rate matching or punching on a PUSCH of a random access message corresponding to the target PO according to the time-frequency resource of the target RO, that is, a PUSCH obtained by performing rate matching or punching on a PUSCH of a random access message corresponding to the target PO according to the time-frequency resource of the target RO.

Optionally, in a case that the time-frequency resources of the target PO and the time-frequency resources of the at least two ROs overlap, the target RO may include one or more of the at least two ROs. For example, referring to fig. 3c, the time-frequency resource of PO1, the time-frequency resource of RO3, and the time-frequency resource of RO4 are overlapped, the target PUSCH may be a PUSCH of the random access message corresponding to PO1, which is rate-matched or punctured according to the time-frequency resource of RO3, may be a PUSCH of the random access message corresponding to PO1, which is rate-matched or punctured according to the time-frequency resource of RO4, or may be a PUSCH of the random access message corresponding to PO1, which is rate-matched or punctured according to the time-frequency resource of RO3 and the time-frequency resource of RO 4.

In this embodiment, by receiving the PUSCH after rate matching or puncturing on the target PO, a manner is provided for transmitting the random access message when the time domain resource of the PO and the time domain resource of the RO used for transmitting the random access message overlap with each other, so that the influence on the information transmission performance due to the resource overlap can be reduced.

In this embodiment, the network side device may configure the frequency domain resources of each PO for random access message transmission to be distributed in the uplink transmission bandwidth in a discontinuous manner. The uplink transmission bandwidth may be located in a licensed frequency band or an unlicensed frequency band. Specifically, the uplink transmission Bandwidth may be a currently activated uplink Bandwidth Part (i.e., active UL Bandwidth Part), or an initial uplink Bandwidth Part (i.e., initial UL BWP), or a frequency domain resource configured by the network side for transmitting the random access message.

Optionally, in a case where the random access process is initiated in the unlicensed frequency band, the uplink transmission bandwidth may be an unlicensed frequency band bandwidth, that is, frequency domain resources of each PO for transmitting the random access message may be distributed in the unlicensed frequency band bandwidth in a discontinuous manner.

In this embodiment, the network side device may configure the frequency domain resources of at least two POs with the same time domain resource to be distributed in the uplink transmission bandwidth in an interleaving manner. For example, referring to fig. 3c, the time domain resources of PO1 and PO2 are the same, and PO1 and PO2 are distributed in an interleaved manner over the unlicensed band bandwidth in the frequency domain.

In this embodiment, the network side device may configure at least two ROs used for the random access message transmission, and the at least two ROs are consecutive in a time domain. The target RO may be any of the at least two ROs. For example, referring to fig. 3a or 3b, the configured 5 ROs (i.e., RO1 through RO5) are consecutive in the time domain.

In this embodiment, the network side device may configure that the RO for the random access message transmission and the at least one PO for the random access message transmission are consecutive in a time domain. For example, referring to fig. 3a or fig. 3b, RO1 and PO1 are contiguous in the time domain,RO2and PO2 are contiguous in the time domain. For another example, referring to fig. 3c, RO1 is temporally contiguous with PO1 and PO2, respectively, and RO2 is also temporally contiguous with PO1 and PO2, respectively.

In this embodiment, the network side device may configure association of ROs and POs that are consecutive in a time domain, so that the PRACH and the PUSCH of the random access message may be transmitted through the associated ROs and POs, respectively.

Optionally, in practical applications, the network side device may send, to the terminal device, configuration information for a random access procedure (e.g., a 2-step random access procedure), where the configuration information may be used to indicate time-frequency resources of at least two ROs and time-frequency resources of at least two POs. Optionally, the time-frequency resources of the at least two ROs may be continuous in a time domain. Alternatively, an RO of the at least two ROs may be temporally continuous with at least one PO of the at least two POs. Optionally, the time-frequency resources of the POs of the at least two POs may overlap with the time-frequency resources of at least one RO of the at least two ROs. Alternatively, an RO of the at least two ROs may be associated with at least one PO thereof that is consecutive in time. Optionally, the frequency domain resources of the POs of the at least two POs are distributed in the uplink transmission bandwidth in a discontinuous manner.

The following describes a transmission method provided by an embodiment of the present invention with reference to an example:

example one:

taking an example that a system bandwidth of an unlicensed frequency band is 50 Physical Resource Blocks (PRBs), the transmission method provided in this embodiment may include the following steps:

step a1, the UE may obtain configuration information for performing a 2-step random access procedure from the network side.

The configuration information may be used to indicate the following resource configurations:

5 ROs (i.e., PRACH occupancy) which are consecutive in time are configured in one time Slot (i.e., Slot), such as the ROs 1 through 5 shown in fig. 3a or fig. 3b, and the frequency domain resource bandwidth of each RO may be 12 PRBs, for example, the frequency domain resource of an RO may be located in PRB # 20-31 of the unlicensed frequency band bandwidth;

4 POs (i.e. PUSCH occupancy) are configured in the Slot, such as POs 1 to PO4 shown in fig. 3a or fig. 3b, each PO is respectively time-continuous with one RO and is associated with it, and PRACH and PUSCH of msgA of 2-step RACH can be transmitted on the associated RO and PO, respectively;

the frequency domain resource bandwidth of the PO is 50 PRBs, namely the PO is distributed on the whole unauthorized frequency band;

PO1 and RO2 overlap each other in PRB # 20-31, PO2 and RO3 overlap each other in PRB # 20-31, and so on.

In step a2, the UE may perform LBT on the channel before any occupancy (including RO or PO) in the Slot starts, and if the channel sensing result is that the channel is idle, the UE may send msgA.

Specifically, the step a2 may include:

if the UE senses that the channel is free before the RO1, the UE may send msgA at RO1 and PO 1; under the condition that the time-frequency resource of the PO1 is partially overlapped with the time-frequency resource of the RO2, the UE can map the msgA PUSCH to the time-frequency resource where the PO1 is not overlapped with the RO2 in a rate matching manner;

if the UE detects that the channel is idle before PO2, the UE may send msgA PUSCH at PO 2; under the condition that the time-frequency resource of the PO2 and the time-frequency resource of the RO3 are partially overlapped, the UE can map the msgA PUSCH to the time-frequency resource, of which the PO2 and the RO3 are not overlapped, in a rate matching manner;

if the UE senses that the channel is free before the RO4, the UE may send msgA at RO4 and PO 4; for fig. 3a, although there is a partial overlap between the time-frequency resource of PO4 and the time-frequency resource of RO5, since RO5 is not a valid RO (i.e. RO5 is an invalid RO), the UE can map msgA PUSCH to all the time-frequency resources of PO 4; for fig. 3b, there is a partial overlap between the time frequency resource of PO4 and the time frequency resource of RO5, and RO5 is a valid RO, so the UE can map msgA PUSCH on the time frequency resource where PO4 and RO5 do not overlap in a rate matching manner.

Example two:

taking the system bandwidth of the unlicensed frequency band as 50 PRBs as an example, the transmission method provided in this embodiment may include the following steps:

step b1, the UE may obtain configuration information for performing the 2-step random access procedure from the network side.

In step b2, the UE may perform LBT on the channel before any occupancy (including RO or PO) in the Slot starts, and if the channel sensing result is that the channel is idle, the UE may send msgA.

Specifically, the step b2 may include:

if the UE senses that the channel is free before the RO1, the UE may send msgA at RO1 and PO 1; under the condition that the time frequency resource of PO1 is partially overlapped with the time frequency resource of RO2, the UE can map msgAPUSCH to PO1 and punch msgA PUSCH on the time frequency resource where PO1 is overlapped with RO 2;

if the UE detects that the channel is idle before PO2, the UE may send msgA PUSCH at PO 2; under the condition that the time frequency resource of PO2 is partially overlapped with the time frequency resource of RO3, the UE can map msgAPUSCH to PO2 and punch msgA PUSCH on the time frequency resource where PO2 is overlapped with RO 3;

if the UE senses that the channel is idle before the RO4, the UE may send msgA at RO4 and PO 4; for fig. 3a, although there is a partial overlap between the time-frequency resource of PO4 and the time-frequency resource of RO5, since RO5 is not a valid RO (i.e. RO5 is an invalid RO), the UE can map msgA PUSCH to all the time-frequency resources of PO 4; for fig. 3b, there is partial overlap of the time-frequency resources of PO4 and RO5, and RO5 is a valid RO, so the UE can map msgA PUSCH to PO4 and puncture msgA PUSCH on the time-frequency resources where PO4 and RO5 overlap.

Example three:

step c1, the UE may obtain the configuration information for performing the 2-step random access procedure from the network side.

within one Slot, 6 ROs which are consecutive in the time-frequency domain are configured, such as RO1 to RO6 shown in fig. 3c, wherein the frequency domain resource bandwidth of each RO may be 12 PRBs, for example, the frequency domain resources of RO1 and RO2 are located in PRBs # 13-24 and PRB # 25-36 of the unlicensed band bandwidth, respectively;

within the Slot, 4 POs, such as PO 1-PO 4 shown in fig. 3c, are configured, wherein each PO is temporally consecutive with and associated with one RO, respectively;

at the time of a PO, the frequency domain resources of the PO are distributed on the bandwidth of the unlicensed frequency band in an interleaving (i.e. Interlace) manner, the number of interleaving is 2, as shown in fig. 3c, the time domain resources of the PO1 and the PO2 are the same, and the frequency domain is allocated in the interleaving manner;

RO1 is associated with PO1, RO2 is associated with PO2, wherein PRACH and PUSCH of random access message msgA of 2-step RACH may be transmitted on the associated RO and PO, respectively;

PO1, PO2 and RO3, RO4 overlap in PRB # 13-36, PO3, PO4 and RO5, RO6 overlap in PRB # 13-36.

In step c2, the UE may perform LBT on the channel before any occupancy (including RO or PO) in the Slot starts, and if the channel sensing result is that the channel is idle, the UE may send msgA.

Specifically, the step c2 may include:

if the UE senses that the channel is free before the RO1, the UE may send msgA at RO1 and PO 1; under the condition that the time frequency resource of PO1 and the time frequency resource of RO3/RO4 are partially overlapped, the UE can map the msgA PUSCH to the time frequency resource which is not overlapped by PO1 and RO3/RO4 in a rate matching mode;

if the UE monitors that the channel is idle before PO2, the UE can send msgA PUSCH at PO 2; under the condition that the time frequency resource of the PO2 and the time frequency resource of the RO3/RO4 are partially overlapped, the UE can map the msgA PUSCH to the time frequency resource, of which the PO2 and the RO3/RO4 do not overlap, in a rate matching manner.

In summary, with the transmission method provided by the embodiment of the present invention, in an unlicensed frequency band, if the network side configures 2-step RACH msgA for transmission on continuous resources, it can be ensured that the msgA transmission meets the requirements of the OCB; in addition, if the PRACH and the PUSCH are configured on continuous time domain resources, the channel access opportunity of the unlicensed frequency band may be improved.
