In a wireless communication system, when a base station and a UE (User Equipment) are out of synchronization, the UE needs to perform random access.

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In a wireless communication system, when a base station and a UE (User Equipment) are out of synchronization, the UE needs to perform random access. For example, when the UE sends an SR (Scheduling Request) to the base station because there is Uplink data to be transmitted, if the UE has no available PUCCH (Physical Uplink Control Channel) resource for transmitting the SR, the UE performs random access.
In the related art, when performing Random Access, the UE may select a PRACH (Physical Random Access Channel) opportunity (english: acquisition) that is most advanced in a time domain from PRACH opportunities available to the UE to transmit a Random Access preamble, so that the base station completes Random Access according to the Random Access preamble. The PRACH opportunity available to the UE may be a PRACH opportunity located after the random access initiation time in a time domain among a plurality of PRACH opportunities periodically configured in the time domain by the wireless communication system, or the PRACH opportunity available to the UE may be at least one PRACH opportunity indicated by a base station through DCI (Downlink Control Information) or a higher layer signaling.
For example, if the time when the random access is initiated is time t, PRACH opportunities a, b, and c located after time t in the time domain may be PRACH opportunities available to the UE, and among the PRACH opportunities a, b, and c, the UE may select PRACH opportunity a located most forward in the time domain to transmit the random access preamble. For another example, the PRACH opportunities indicated by the base station include PRACH opportunities d, e, and f, which are available to the UE, and among the PRACH opportunities d, e, and f, the UE may select the PRACH opportunity d that is most advanced in the time domain to transmit the random access preamble.
In practical applications, a PRACH opportunity selected by the UE may overlap with an Uplink resource that the UE needs to use for Uplink transmission in a time domain, for example, the PRACH opportunity selected by the UE and a pusch (physical Uplink Shared channel) resource that the base station allocates to the UE for transmitting Uplink communication data are located in the same time slot. In this case, the UE needs to allocate the available transmission power to the random access preamble and the uplink transmission at the same time, which is easy to occur when the transmission power of the random access preamble is insufficient, which affects the success rate of the random access.
The embodiment of the disclosure provides an uplink transmission method, in the process of random access, when a target uplink resource overlapping with a first PRACH opportunity in a time domain exists, UE (user equipment) can determine a second PRACH opportunity and transmits a random access preamble through the second PRACH opportunity, wherein when the UE transmits the random access preamble through the second PRACH opportunity, the target uplink transmission overlapping with the second PRACH opportunity in the time domain does not exist, so that the situation that the UE allocates available transmission power to the random access preamble and the uplink transmission at the same time can be avoided, the transmission power of the random access preamble can be ensured, and the success rate of the random access can be improved.
Next, the embodiment of the present disclosure will describe an implementation environment related to the uplink transmission method: as shown in fig. 1, the implementation environment may include a base station 10 and a UE 20, the base station 10 and the UE 20 may be connected through a communication network, and the UE 20 is any UE in a cell served by the base station 10. The Communication network may be a 5G (Fifth Generation Mobile Communication Technology) Communication network, an LTE (Long Term Evolution) Communication network, or another Communication network similar to The LTE Communication network or The 5G Communication network.
Fig. 2 is a flowchart illustrating an uplink transmission method according to an exemplary embodiment, where the uplink transmission method is used in the UE 20 shown in fig. 1, and as shown in fig. 2, the uplink transmission method may include the following steps.
When the random access preamble is transmitted through the second PRACH opportunity, the UE does not have a target uplink transmission that overlaps with the second PRACH opportunity in a time domain, where the target uplink transmission is other types of uplink transmissions except for the random access preamble transmission.
The first PRACH opportunity is a PRACH opportunity that is most ahead in a time domain among at least one PRACH opportunity available to the UE, and the target uplink resource is an uplink resource that the UE needs to use for target uplink transmission.
To sum up, in the uplink transmission method provided in the embodiment of the present disclosure, in the process of random access, when there is a target uplink resource overlapping with the first PRACH opportunity in the time domain, the UE determines a second PRACH opportunity, and transmits a random access preamble through the second PRACH opportunity, where there is no target uplink transmission overlapping with the second PRACH opportunity in the time domain when the UE transmits the random access preamble through the second PRACH opportunity, so that it is avoided that the UE allocates available transmission power to the random access preamble and uplink transmission at the same time, and thus, the transmission power of the random access preamble can be ensured, and the success rate of random access is improved.
Fig. 3 is a flowchart illustrating an uplink transmission method according to an exemplary embodiment, where the uplink transmission method is used in the implementation environment shown in fig. 1, and as shown in fig. 3, the uplink transmission method may include the following steps.
In practical application, according to different devices for initiating random access, random access can be divided into two types, one type is a type for initiating random access by UE, as the name implies, the type of random access is initiated by UE, and the other type is a type for initiating random access by base station, and the type of random access is initiated by base station.
When the type of the random access is a type that the UE initiates the random access, the PRACH opportunity available to the UE may be a PRACH opportunity located after the time of initiating the random access in a time domain among a plurality of PRACH opportunities periodically configured by the wireless communication system. When the type of the random access is a type in which the base station initiates the random access, the PRACH opportunity available to the UE may be at least one PRACH opportunity indicated by the base station through DCI or a higher layer signaling, where the higher layer signaling may be an RRC (Radio Resource Control) signaling or the like.
In random access, the UE may determine at least one PRACH opportunity available to itself, and determine a first PRACH opportunity from the at least one PRACH opportunity available to itself, where the first PRACH opportunity may be a temporally top PRACH opportunity of the at least one PRACH opportunity available to the UE.
The target uplink resource is an uplink resource that the UE needs to use for the target uplink transmission, in other words, the target uplink resource is a resource for carrying a certain target uplink transmission of the UE. The target uplink transmission is other types of uplink transmission except for random access preamble transmission, and in practical application, the target uplink transmission may include uplink control Information transmission, uplink communication data transmission, or uplink signal transmission, where the uplink control Information transmission may include HARQ (Hybrid Automatic Repeat Request), SR transmission, or CSI (Channel State Information) transmission, and the uplink signal transmission may include uplink reference signal transmission, and the like. The target uplink resource may be a PUCCH resource or a PUSCH resource.
In the related art, when there is a target uplink resource overlapping with the first PRACH opportunity in the time domain, the UE needs to allocate available transmission power to the random access preamble and a target uplink transmission carried by the target uplink resource at the same time, which easily causes insufficient transmission power of the random access preamble, and then affects the success rate of random access. Wherein, the overlapping of the first PRACH opportunity and the target uplink resource in the time domain means: an intersection exists between the time domain resource occupied by the first PRACH opportunity and the time domain resource occupied by the target uplink resource.
In order to avoid this situation, in the embodiment of the present disclosure, when there is a target uplink resource overlapping with the first PRACH opportunity in the time domain, the UE may determine a second PRACH opportunity, where when the random access preamble is transmitted through the second PRACH opportunity, the UE does not have a target uplink transmission overlapping with the second PRACH opportunity in the time domain, so that a situation that the UE allocates available transmission power to the random access preamble and the uplink transmission at the same time may be avoided, and then the transmission power of the random access preamble may be ensured, and the success rate of the random access may be improved.
The disclosed embodiments provide three exemplary ways for the UE to determine the second PRACH opportunity:
in the first mode, the UE determines the second PRACH opportunity in at least one available PRACH opportunity, where the second PRACH opportunity determined by the UE is not overlapped with any uplink resource that the UE needs to use for target uplink transmission in a time domain.
Optionally, the UE may determine at least one uplink resource that the UE needs to use for performing the target uplink transmission, and at the same time, the UE may determine at least one PRACH opportunity that the UE may use, and then, the UE may determine at least one candidate PRACH opportunity from the at least one PRACH opportunity, where the candidate PRACH opportunity is not overlapped with any uplink resource that the UE needs to use for performing the target uplink transmission in the time domain, and the UE may determine a PRACH opportunity that is most advanced in the time domain in the at least one candidate PRACH opportunity as the second PRACH opportunity.
For example, the PRACH opportunities available to the UE may include PRACH opportunities a, b, c, and d, where PRACH opportunity a is located in slot 1, PRACH opportunity b is located in slot 2, PRACH opportunity c is located in slot 3, PRACH opportunity b is located in slot 4, a PUSCH resource configured by the base station for the UE to transmit uplink communication data is located in slot 1, and a PUCCH resource required by the UE to transmit HARQ is located in slot 2, the UE may determine PRACH opportunity c and PRACH opportunity d, which are not overlapped with the PUSCH resource and the PUCCH resource in the time domain, as candidate PRACH opportunities, and then the UE may determine PRACH opportunity c, which is most advanced in the time domain, of the PRACH opportunity c and the PRACH opportunity d as a second PRACH opportunity.
In a second manner, the UE may prohibit itself from performing target uplink transmission via the target uplink resource, and determine the first PRACH opportunity as the second PRACH opportunity.
In order to ensure the transmission power of the random access preamble, the UE may prohibit itself from performing target uplink transmission through the target uplink resource, so that when the UE transmits the random access preamble through the first PRACH opportunity, it is not necessary to simultaneously allocate the available transmission power to the random access preamble and the target uplink transmission carried by the target uplink resource, thereby ensuring the transmission power of the random access preamble.
For example, in the above example, the PRACH opportunity a may be a first PRACH opportunity, that is, the first PRACH opportunity is located in slot 1, and a PUSCH resource configured by the base station for the UE to transmit uplink communication data is also located in slot 1, in which case, the UE may prohibit transmission of the uplink communication data through the PUSCH resource, and determine the PRACH opportunity a as a second PRACH opportunity.
Optionally, the UE may compare the transmission priority of the target uplink transmission with the transmission priority of the random access preamble, and it should be noted that the target uplink transmission may refer to a target uplink transmission that is used by the target uplink resource for carrying. When the transmission priority of the random access preamble is higher than the transmission priority of the target uplink transmission, the UE needs to preferentially ensure normal transmission of the random access preamble, and in this case, the UE may select the second manner to determine the second PRACH opportunity, that is, the UE may prohibit itself from performing the target uplink transmission through the target uplink resource, and determine the first PRACH opportunity as the second PRACH opportunity.
In the third mode, the UE prohibits the UE from transmitting the random access preamble code through the first PRACH opportunity and starts new random access, and the UE determines the second PRACH opportunity when the new random access is carried out.
In order to avoid that the UE allocates the available transmission power to the random access preamble and the target uplink transmission used for the bearer of the target uplink resource at the same time, which results in insufficient transmission power of the random access preamble, the UE may prohibit itself from transmitting the random access preamble through the first PRACH opportunity, and may initiate a new random access at the same time, and when performing the new random access, the UE may determine the second PRACH opportunity. It should be noted that, in the new random access process, the manner of determining the second PRACH opportunity by the UE is the same as the technical process of step 302 in this embodiment, and details of the embodiment of the present disclosure are not repeated herein.
For example, in the above example, the PRACH opportunity a may be a first PRACH opportunity, that is, the first PRACH opportunity is located in time slot 1, and a PUSCH resource configured by the base station for the UE and used for transmitting uplink communication data is also located in time slot 1, in this case, the UE may prohibit transmission of a random access preamble through the PRACH opportunity a, and at the same time, the UE may transmit uplink communication data through the PUSCH resource, and then the UE may initiate new random access, and when new random access is performed, the UE may determine the second PRACH opportunity.
Optionally, the UE may compare the transmission priority of the target uplink transmission with the transmission priority of the random access preamble, and it should be noted that the target uplink transmission may refer to a target uplink transmission that is used by the target uplink resource for carrying. When the transmission priority of the random access preamble is lower than the transmission priority of the target uplink transmission, the UE needs to preferentially perform the target uplink transmission, and in this case, the UE may select the third method to determine the second PRACH opportunity, that is, the UE may prohibit itself from transmitting the random access preamble through the first PRACH opportunity and initiate a new random access, and when performing the new random access, the UE determines the second PRACH opportunity.
It should be noted that, in practical applications, there is a high possibility that the available transmit power of the UE is greater than the preset power threshold, and in this case, because the available transmit power of the UE is relatively high, even if the UE needs to allocate the available transmit power to the random access preamble and the target uplink transmission used by the target uplink resource for the bearer at the same time, the UE can ensure the transmit power of the random access preamble. At this time, the UE may not determine the second PRACH opportunity, but directly transmit the random access preamble through the first PRACH opportunity, and simultaneously perform target uplink transmission through the target uplink resource.
Optionally, under the condition that the UE directly transmits the random access preamble through the first PRACH opportunity and performs target uplink transmission through the target uplink resource, the UE may allocate transmission power for the target uplink transmission carried by the random access preamble and the target uplink resource according to a certain policy. For example, in one possible implementation manner, the UE may compare the transmission priority of the target uplink transmission with the transmission priority of the random access preamble, and it should be noted that the target uplink transmission refers to the target uplink transmission that may be used by the target uplink resource for the bearer. The UE may then allocate transmit power for the random access preamble and the target uplink transmission based on the comparison. Optionally, when the comparison result is that the transmission priority of the target uplink transmission is smaller than the transmission priority of the random access preamble, the UE may preferentially allocate the transmission power to the random access preamble, and after sufficient transmission power is allocated to the random access preamble, the UE may allocate the remaining available transmission power to the target uplink transmission, and when the comparison result is that the transmission priority of the target uplink transmission is greater than the transmission priority of the random access preamble, the UE may preferentially allocate the transmission power to the target uplink transmission, and after sufficient transmission power is allocated to the target uplink transmission, the UE may allocate the remaining available transmission power to the random access preamble.
After allocating transmission power for target uplink transmission carried by the random access preamble and the target uplink resource, the UE may transmit the random access preamble through the first PRACH opportunity based on the allocated transmission power, and perform the target uplink transmission through the target uplink resource.
Certainly, in practical application, there may be a case that the available transmission power of the UE is not greater than the preset power threshold, and in this case, the UE may select the second or third manner to determine the second PRACH opportunity, that is, the UE may prohibit itself from performing target uplink transmission through the target uplink resource and determine the first PRACH opportunity as the second PRACH opportunity, or the UE may prohibit itself from transmitting the random access preamble through the first PRACH opportunity and initiate new random access, and when new random access is performed, the UE determines the second PRACH opportunity.
It should be noted that, in the second and third manners, a MAC (Media Access Control) layer of the UE may execute a technical process for determining the second PRACH opportunity, or a physical layer of the UE may execute a technical process for determining the second PRACH opportunity, which is not specifically limited in this embodiment of the present disclosure.
In this embodiment of the present disclosure, the UE may determine which of the three manners needs to be selected to determine the second PRACH opportunity according to the type of random access, the type of target uplink transmission, and the transmission priority of the triggered uplink data.
Optionally, in a possible implementation manner, the UE may determine which of the three manners needs to be selected to determine the second PRACH opportunity according to the type of machine access.
In this implementation manner, the UE may obtain the current type of random access, and as described above, the type of random access may include a type of random access initiated by the UE and a type of random access initiated by the base station, and the UE may determine the second PRACH opportunity according to the type of random access, that is, determine which of the three manners is selected to determine the second PRACH opportunity.
For example, when the current type of random access is a type in which the UE initiates random access, the UE may select the first manner to determine the second PRACH opportunity, and when the current type of random access is a type in which the base station initiates random access, the UE may select any one of the first manner, the second manner, and the third manner to determine the second PRACH opportunity.
Optionally, in another possible implementation manner, the UE may determine, according to the type of the target uplink transmission, which of the three manners needs to be selected to determine the second PRACH opportunity.
In this manner, the UE may obtain the type of the target uplink transmission, as described above, the type of the target uplink transmission may include an uplink control information transmission type, an uplink communication data transmission type, an uplink signal transmission type, and the like, and the UE may determine the second PRACH opportunity according to the type of the target uplink transmission, that is, determine which of the three manners is selected to determine the second PRACH opportunity.
For example, when the type of the target uplink transmission is an uplink communication data transmission type, the UE may select the first manner to determine the second PRACH opportunity.
Optionally, in another possible implementation manner, the UE may determine, according to the transmission priority of the trigger uplink data, which of the three manners needs to be selected to determine the second PRACH opportunity.
For example, when the UE sends an SR to the base station because there is uplink data 1 to be transmitted, if the UE does not have available PUCCH resources for transmitting the SR, the UE needs to perform random access, and in this case, the uplink data 1 is the triggered uplink data.
In this way, the UE may compare the transmission priority of the trigger uplink data with the transmission priority of the target uplink transmission, where the target uplink transmission is uplink transmission carried by the target uplink resource, and then the UE may determine the second PRACH opportunity according to the comparison result, that is, determine which of the three manners is selected to determine the second PRACH opportunity. For example, when the transmission priority of the triggered uplink data is greater than the transmission priority of the target uplink transmission, the UE needs to preferentially ensure transmission of the random access preamble, at this time, the UE may select the second method to determine the second PRACH opportunity, and when the transmission priority of the triggered uplink data is not greater than the transmission priority of the target uplink transmission, the UE needs to preferentially perform the target uplink transmission, at this time, the UE may select the third method to determine the second PRACH opportunity.
To sum up, in the uplink transmission method provided in the embodiment of the present disclosure, in the process of random access, when there is a target uplink resource overlapping with the first PRACH opportunity in the time domain, the UE determines a second PRACH opportunity, and transmits a random access preamble through the second PRACH opportunity, where there is no target uplink transmission overlapping with the second PRACH opportunity in the time domain when the UE transmits the random access preamble through the second PRACH opportunity, so that it is avoided that the UE allocates available transmission power to the random access preamble and uplink transmission at the same time, and thus, the transmission power of the random access preamble can be ensured, and the success rate of random access is improved.
