After the UE triggers a Buffer Status Report (BSR) to Report, if no uplink resource can send the BSR, the UE triggers a Scheduling Request (SR) to send. The SR resources may be configured on one or more cells.
When a Media Access Control (MAC) entity of the UE triggers an SR procedure and an RACH procedure, transmission timings of the SR and PRACH may overlap. If the SR and PRACH resources are in the same cell, the UE cannot transmit the SR and PRACH at the same time. If the SR and PRACH resources are in different cells, the UE may not be able to transmit the SR and PRACH simultaneously due to the limitation of uplink transmission power.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The following briefly describes the related art of the present invention.
The triggering events for the random access procedure of the current fifth Generation (5Generation, 5G) communication system include:
radio Resource Control (RRC) IDLE (IDLE) initial access;
RRC connection reestablishment;
cell switching, namely switching a terminal from one cell to another cell in a connected state;
uplink or downlink data arrives and uplink is out of step;
RRC INACTIVE state (INACTIVE) connection establishment;
a system information request;
and recovering the beam failure.
After the random access process is triggered, the UE selects a random access resource to transmit a PRACH signal.
The embodiment of the invention provides an uplink transmission method and a terminal, aiming at the problem that the terminal cannot determine which uplink transmission is performed when the transmission time of SR and PRACH are overlapped because the terminal cannot perform different uplink transmissions at the same time, so that network communication faults are caused.
As shown in fig. 1, an uplink transmission method provided in an embodiment of the present invention is applied to a terminal, and includes:
step 101, when at least two uplink transmissions to be sent triggered by a terminal conflict in transmission time, determining a first uplink transmission to perform uplink transmission sending in the at least two uplink transmissions to be sent;
it should be noted that the collision here refers to the overlapping of the transmission times, for example, the transmission times are partially or completely overlapped; in the embodiment of the present invention, the at least two uplink transmissions to be transmitted that collide at the transmission time refer to one of the following situations:
case one, at least one Scheduling Request (SR) transmission and at least one Physical Random Access Channel (PRACH) transmission collide at transmission time, e.g., one SR transmission and one PRACH transmission collide at transmission time;
case two, at least two SR transmissions collide at transmission time, e.g., one SR transmission and another SR transmission collide at transmission time;
case three, at least two PRACH transmissions collide at transmission time, e.g., one PRACH transmission and another PRACH transmission collide at transmission time.
It should be noted that, the step of determining that the first uplink transmission performs uplink transmission sending in the at least two uplink transmissions to be sent may be implemented according to whether to distinguish whether the sending resources of the at least two uplink transmissions to be sent are in the same cell, and the following two ways are respectively described as follows.
Firstly, when distinguishing whether at least two sending resources of uplink transmission to be sent are in the same cell
When the specific implementation of determining that the first uplink transmission carries out uplink transmission sending in the at least two uplink transmissions to be sent includes one of the following modes:
when the transmission resources of the at least two uplink transmissions to be sent are in the same cell, determining that the first uplink transmission carries out uplink transmission sending according to the priority rule of the triggering conditions of the at least two uplink transmissions to be sent;
it should be noted that, when transmission resources are in the same cell, the terminal can only select one uplink transmission to transmit, and at this time, it needs to determine which uplink transmission to transmit according to the priority rule of the triggering conditions of at least two uplink transmissions to be transmitted.
And secondly, when the transmission resources of the at least two uplink transmissions to be sent are not in the same cell, determining that the first uplink transmission carries out uplink transmission sending according to the priority rules of the triggering conditions of the at least two uplink transmissions to be sent and the uplink sending power of the terminal.
It should be noted that, when transmission resources are not in the same cell, the terminal may first determine whether simultaneous transmission of at least two uplink transmissions to be sent is satisfied according to its own uplink transmission power, and if the uplink transmission power allows simultaneous transmission of at least two uplink transmissions to be sent (that is, the uplink transmission power of the terminal is not limited), then at least two uplink transmissions to be sent that collide in transmission time are both sent; if the uplink transmission power does not allow to simultaneously transmit at least two uplink transmissions to be transmitted (i.e. the uplink transmission power of the terminal is limited, i.e. the sum of the transmission powers of at least two uplink transmissions to be transmitted exceeds the uplink transmission power of the terminal), the terminal needs to determine which uplink transmission or uplink transmissions to transmit according to the priority rule of the trigger condition of at least two uplink transmissions to be transmitted.
Secondly, when at least two sending resources of uplink transmission to be sent are not distinguished to be in the same cell or not
When the specific implementation of determining that the first uplink transmission carries out uplink transmission sending in the at least two uplink transmissions to be sent includes one of the following modes:
determining that the first uplink transmission carries out uplink transmission sending according to the priority rules of the triggering conditions of the at least two uplink transmissions to be sent;
and secondly, determining the first uplink transmission to perform uplink transmission according to the priority rules of the triggering conditions of the at least two uplink transmissions to be transmitted and the uplink transmission power of the terminal.
It should be noted that, in this case, the terminal may directly determine which uplink transmission to send according to the priority rule of the triggering conditions of the at least two uplink transmissions to be sent; or the terminal may first determine whether simultaneous transmission of at least two uplink transmissions to be transmitted is satisfied according to its own uplink transmission power, and if the uplink transmission power allows simultaneous transmission of at least two uplink transmissions to be transmitted, at least two uplink transmissions to be transmitted that collide over transmission time are both transmitted; if the uplink transmission power does not allow to simultaneously transmit at least two uplink transmissions to be transmitted, the terminal needs to determine which one or more uplink transmissions to transmit according to the priority rule of the trigger conditions of the at least two uplink transmissions to be transmitted.
It should be further noted that, in the above manner, the priority rule of the trigger conditions of the at least two uplink transmissions to be sent includes at least one of the following items:
a1, the priority of the uplink transmission triggered by the high-priority service is higher than that of the uplink transmission triggered by the low-priority service;
for example, there are logical channel 1 triggered uplink transmission and logical channel 2 triggered uplink transmission, where the priority of logical channel 1 is higher than the priority of logical channel 2, and correspondingly, the priority of logical channel 1 triggered uplink transmission is higher than the priority of logical channel 2 triggered uplink transmission.
A1, the priority of the uplink transmission triggered by the trigger event with high priority is higher than that of the uplink transmission triggered by the trigger event with low priority.
For example, there are event 1 triggered uplink transmission and event 2 triggered uplink transmission, where the priority of event 1 is higher than the priority of event 2, and correspondingly, the priority of event 1 triggered uplink transmission is higher than the priority of event 2 triggered uplink transmission.
It should be noted that the type of the trigger event herein includes at least one of the following items:
b1, the terminal is initially accessed when being switched from an idle state to a connected state;
b2, RRC connection reestablishment;
b3, switching cells, namely switching the terminal from one cell to another cell in a connected state;
b4, up or down data arrives and up goes out of step;
b5, establishing RRC non-activated state connection;
b6, system information request;
b7, beam failure recovery;
b8, buffer status report.
The uplink transmission is triggered when any of the above trigger events occurs.
It should be noted that, when the terminal determines that the first uplink transmission performs uplink transmission sending in the at least two uplink transmissions to be sent, the terminal may know which specific second uplink transmissions that are not to be sent are, specifically, other uplink transmissions except the first uplink transmission in the at least two uplink transmissions to be sent are the second uplink transmissions, and the terminal may further perform a corresponding processing procedure according to the second uplink transmissions, because the second uplink transmissions may include at least one of SR transmission and PRACH transmission, and the processing procedures of the terminal for SR transmission and PRACH transmission are different, the following description of the processing procedures of the terminal for performing SR transmission and PRACH transmission respectively is provided below.
One, when the second uplink transmission includes SR transmission
The processing mode of the terminal comprises one of the following modes:
c1, determining to stop the SR transmission;
and when the SR transmission cannot be transmitted, stopping the SR transmission.
C2, triggering the random access process;
upon determining that the SR transmission cannot be transmitted, a random access procedure is performed.
And C3, stopping the current SR transmission, and judging whether the SR transmission can be carried out at the resource position of the next SR transmission.
When it is determined that the SR transmission cannot be sent, the SR transmission of this time is stopped (that is, the resource location of the SR transmission of this time is skipped), but the terminal needs to determine again according to the subsequent situation as to whether the resource location of the SR transmission of the next time can be SR transmitted.
It should be further noted that, since the terminal maintains the SR transmission counter during SR transmission, when the terminal stops the SR transmission this time and determines whether SR transmission is possible at the resource location of the next SR transmission, a specific processing manner of the SR transmission counter includes one of the following manners:
for the stopped SR transmission, the SR sending counter does not accumulate;
for a stopped SR transmission, the SR transmission counter increments by one, i.e. in this case, the count value of the SR transmission counter is: SR _ COUNTER + 1.
Secondly, when the second uplink transmission comprises PRACH transmission
The processing mode of the terminal comprises one of the following modes:
d1, stopping the random access process corresponding to the PRACH transmission;
and when the PRACH transmission cannot be sent, immediately stopping the random access process corresponding to the PRACH transmission.
D2, determining that the state of the random access process corresponding to the PRACH transmission is a failure state;
obtaining a random access procedure failure when it is determined that the PRACH transmission cannot be transmitted.
D3, determining the state of the random access process corresponding to the PRACH transmission as a success state;
when it is determined that the PRACH transmission cannot be transmitted, the random access procedure is successful.
And D4, stopping the current PRACH transmission, and judging whether the PRACH transmission can be carried out at the resource position of the next PRACH transmission.
When it is determined that the PRACH transmission cannot be sent, the PRACH transmission of this time is stopped (that is, the resource location of the PRACH transmission of this time is skipped), but for whether the resource location of the PRACH transmission of the next time can be used for PRACH transmission, the terminal needs to determine again according to subsequent conditions.
It should be further noted that, because the terminal correspondingly maintains a PRACH power ramp-up counter and a PRACH transmission frequency counter during PRACH transmission, specifically, when stopping the current PRACH transmission and determining whether PRACH transmission is possible at a resource location of a next PRACH transmission, a specific processing manner of the PRACH power ramp-up counter includes one of the following manners:
for the stopped PRACH transmission, the PRACH power ramp counter does not accumulate;
for a stopped PRACH transmission, the PRACH power ramp-up counter increments by one, i.e. in this case, the count value of the PRACH power ramp-up counter is: PREAMBLE _ POWER _ forwarding _ COUNTER + 1.
The specific processing method of the PRACH transmission number counter includes one of the following methods:
for the stopped PRACH transmission, the PRACH sending frequency counter is not accumulated;
for the stopped PRACH transmission, the PRACH transmission number counter increments by one, that is, in this case, the count value of the PRACH transmission number counter is: PREAMBLE _ TRANSMISSION _ COUNTER + 1.
It should be noted that, when at least two uplink transmissions to be sent triggered by the terminal collide with each other in transmission time, one uplink transmission with a higher priority is selected to send, so as to avoid the influence on a high-priority service, and also avoid the delay of excessive services caused by the terminal abandoning all the colliding uplink transmissions, avoid the occurrence of network communication failures, and ensure the reliability of network communication.
As shown in fig. 2, an embodiment of the present invention provides a terminal 200, including:
a sending module 201, configured to determine, when at least two uplink transmissions to be sent triggered by a terminal collide with each other in transmission time, a first uplink transmission in the at least two uplink transmissions to be sent to perform uplink transmission sending;

when the transmission resources of the at least two uplink transmissions to be sent are in the same cell, determining that the first uplink transmission carries out uplink transmission sending according to the priority rule of the triggering conditions of the at least two uplink transmissions to be sent;
and when the transmission resources of the at least two uplink transmissions to be sent are not in the same cell, determining that the first uplink transmission carries out uplink transmission sending according to the priority rules of the triggering conditions of the at least two uplink transmissions to be sent and the uplink sending power of the terminal.
Further, the sending module 201 implements one of the following manners:
determining the first uplink transmission to perform uplink transmission sending according to the priority rules of the triggering conditions of the at least two uplink transmissions to be sent;
and determining the first uplink transmission to perform uplink transmission according to the priority rules of the triggering conditions of the at least two uplink transmissions to be transmitted and the uplink transmission power of the terminal.

the priority of the uplink transmission triggered by the high-priority service is higher than that of the uplink transmission triggered by the low-priority service;

and the first judgment module is used for stopping the current SR transmission and judging whether the SR transmission can be carried out or not at the resource position of the next SR transmission.

the first control module is used for not accumulating the SR transmission counter for the stopped SR transmission;
and the second control module is used for accumulating one by the SR sending counter for the stopped SR transmission.
