Description

Background
The key technology for realizing wide coverage by the technology of the wide-coverage large-connection internet of things, namely enhanced machine type communication (eMTC), is repeated transmission for many times. Repeated transmission for multiple times has retransmission gain, so that the receiving end can successfully receive the signal by sending for multiple times even if the terminal is in a place with very poor signal. If the number of times of repeated transmission is insufficient, the receiving end cannot obtain retransmission receiving gain, and the data sent by the terminal cannot be successfully received, so that the reliability of the data is influenced.
The 3GPP release 14 protocol specifies that if a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH collides with a physical random access channel PRACH with at least one resource block RB, the transmission of the PUCCH or PUSCH is dropped. However, the discarded PUCCH or PUSCH may be counted in the number of repeated transmissions, which results in that the number of true repeated transmissions of the PUCCH or PUSCH is insufficient, and further results in that the reliability of PUCCH or PUSCH transmission is low, so that the reliability of the eMTC user is affected.

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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 embodiment of the invention provides a data transmission method, which is applied to a terminal, wherein the terminal and a base station are communicated with each other.
Referring to fig. 1, the data transmission method may include:
and S11, acquiring conflict processing rules.
The conflict configuration rule is a processing rule when the physical uplink control channel PUCCH or physical uplink shared channel PUSCH conflicts with a physical random access channel PRACH.
In practical applications, the conflict configuration rule may be:
and if the number of the conflict resource blocks meets a preset conflict judgment rule, performing transmission delay operation on the PUCCH or the PUSCH until the resource blocks used by the PUCCH or the PUSCH are idle, and starting to transmit the PUCCH or the PUSCH. And if the number of the conflict resource blocks does not meet a preset conflict judgment rule, discarding the transmission of the PUCCH or the PUSCH.
In another specific implementation manner of the present invention, explaining that the number of the conflicting resource blocks satisfies a preset conflict determination rule, specifically, the number of the conflicting resource blocks satisfies the preset conflict determination rule may include:
1) if the number of the conflict resource blocks is larger than a first preset threshold value, determining that the number of the conflict resource blocks meets a preset conflict judgment rule;
or, 2) determining the number of the conflict resource blocks which are included and is greater than the number of conflict subframes of a second preset threshold value;
and if the number of the conflict sub-frames is larger than a third preset threshold value, determining that the number of the conflict resource blocks meets a preset conflict judgment rule.
The determination of collision may be performed from a time domain and a frequency domain, where the number of collision resource blocks is greater than a first preset threshold, that is, the collision determination is performed from a frequency domain perspective, and the first preset threshold may be zero or a non-zero value, such as 1, 2, or 3. Referring to fig. 2, fig. 2 shows the collision of resource blocks RB of PUCCH or PUSCH and resource blocks RB of PRACH, that is, PUCCH or PUSCH and PRACH occupy the same frequency domain resource of the same subframe. And when the number of the conflict resource blocks is larger than a first preset threshold value, the conflict is considered to occur.
The number of the collision subframes is greater than the third preset threshold, that is, collision judgment is performed from the time domain perspective, referring to fig. 3, i, j + M-1 and i + N-1 all represent subframes, and in fig. 3, a transmission subframe of a PUCCH or PUSCH collides with a transmission subframe of a PRACH. In this embodiment, first, the number of the resource blocks in a subframe is greater than a second preset threshold, and in addition, the number of the resource blocks in the subframe is greater than the second preset threshold, and then the subframe collision in the time domain can be considered. In the prior art, a mode of discarding transmission of the PUCCH and the PUSCH is directly adopted to solve the collision, but the mode can cause insufficient repeated transmission times of the PUCCH or the PUSCH, and further the problem of insufficient transmission times is solved through the collision processing rule in the embodiment of the invention. The first preset threshold and the second preset threshold may be the same or different.
The aforementioned "if the number of the conflicted resource blocks satisfies a preset confliction decision rule, performing a transmission delay operation on the PUCCH or the PUSCH until the resource blocks used by the PUCCH or the PUSCH are idle, starting transmission of the PUCCH or the PUSCH" means:
when the conflict is determined, the transmission of the PUCCH or the PUSCH is suspended, the transmission of the PRACH is still continued at the moment, when the transmission of the PRACH is finished, the resources occupied by the PRACH are released, the resources used for the transmission of the PUCCH or the PUSCH are ensured to be idle at the moment, and then the transmission of the PUCCH or the PUSCH can be started at the moment so as to ensure that the real transmission times of the PUCCH/PUSCH are enough to demodulate.
The above-mentioned "discarding the transmission of the PUCCH or the PUSCH if the number of the colliding resource blocks does not satisfy the preset collision determination rule" means:
if the number of the conflicted resource blocks does not meet the preset conflicted judgment rule, the conflicted resource blocks are not serious, the occasional discarding of the transmission of the PUCCH or the PUSCH does not cause the serious insufficiency of the integrity of the data received by the base station, and further, the transmission of the PUCCH or the PUSCH can be discarded for several times in the scene that the requirement on the integrity of the data is not strict.
S12, when the PUCCH or PUSCH collides with the PRACH, acquiring the number of resource blocks of the collision of the PUCCH or the PUSCH with the PRACH.
Specifically, the terminal may acquire the number of resource blocks in which the PUCCH or the PUSCH collides with the PRACH.
S13, judging whether the number of the conflict resource blocks meets a preset conflict judgment rule; if yes, go to step S14; if not, go to step S15.
S14, performing transmission delay operation on the PUCCH or the PUSCH until the resource block used by the PUCCH or the PUSCH is idle, and starting to transmit the PUCCH or the PUSCH.
S15, discarding the transmission of the PUCCH or the PUSCH.
The detailed explanation of step S14 and step S15 is described above, and please refer to the corresponding description in the above embodiments.
In this embodiment, when a PUCCH or a PUSCH collides with a PRACH and the number of the colliding resource blocks satisfies a preset collision determination rule, a transmission delay operation is performed on the PUCCH or the PUSCH until a resource block used by the PUCCH or the PUSCH is idle, and transmission of the PUCCH or the PUSCH is started. That is, the present invention does not directly discard transmission of PUCCH or PUSCH, but adopts a delayed transmission operation, and when a resource block used by the PUCCH or the PUSCH is idle, transmission of the PUCCH or the PUSCH is started, so that the number of times of repeated transmission of the PUCCH or the PUSCH can be ensured, and further, the reliability of PUCCH or PUSCH transmission and the reliability of eMTC users can be improved, and in addition, performance indexes such as throughput, delay, reliability and the like can be ensured.

And when the conflict does not exist, the PUCCH/PUSCH is normally scheduled.
2. Acquiring the conflict handling rule comprises:
acquiring a message which is sent by a base station and carries the conflict processing rule; the message comprises at least one of a main system information block MIB, a system information block SIB and a radio resource control RRC message.
Specifically, referring to fig. 5, the base station issues the number of collision subframes and/or the number of RBs and a collision processing rule (i.e., a collision processing rule) through the MIB/SIB/RRC message, the base station normally schedules the PUCCH/PUSCH and issues the DCI message for scheduling the PUCCH/PUSCH, the terminal side determines whether the PUCCH/PUSCH collides with the parch when transmitting the PUCCH/PUSCH, and then transmits the PUCCH/PUSCH according to the preset collision processing rule when colliding. And when the conflict does not exist, the PUCCH/PUSCH is normally scheduled.
3. Acquiring the conflict handling rule comprises:
when the base station identifies that the PUCCH or PUSCH collides with the PRACH, the conflict processing rule issued by the base station through a DCI (Downlink Control information) message is acquired.
Referring to fig. 6, a base station normally schedules a PUCCH/PUSCH, when scheduling the PUCCH/PUSCH, a base station side determines, according to a conflict determination rule (conflict determination rule), a subframe number and/or an RB number of the scheduled PUCCH/PUSCH which conflicts with a PRACH, and further determines whether the PUCCH/PUSCH conflicts with the PRACH, if there is a conflict, the base station issues DCI carrying a deferred transmission instruction according to the conflict processing rule (conflict processing rule), a terminal side determines again whether the PUCCH/PUSCH conflicts with the PRACH, and if so, performs PUCCH/PUSCH deferred transmission according to the received DCI carrying the deferred transmission instruction.
