Description

Uplink scheduling-free configuration reconfiguration method, device, terminal and base station
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink scheduling-free configuration reconfiguration method, an uplink scheduling-free configuration reconfiguration device, a terminal, and a base station.
Background
In 5G NR (new air interface), in order to reduce uplink transmission delay, uplink non-scheduled (GF) transmission is introduced. Uplink scheduling is performed without performing a scheduling request, and uplink transmission is performed directly, as shown in fig. 1. Therefore, it is necessary to configure parameters such as transmission resources in advance. From the configuration and transmission scheme point of view, two types are included, type1 and Type 2:
the Type1 uplink scheduling-free transmission is configured by RRC (radio resource control) signaling, that is, parameters related to transmission, such as time domain resources, frequency domain resources, DMRS (demodulation reference signal) configuration, frequency hopping, MCS table (modulation and coding strategy table), power control parameters, period, and number of repeated transmissions, are all preconfigured by RRC, and when uplink data transmission exists in the terminal, the terminal can directly start transmission in the latest uplink scheduling-free transmission opportunity.
The above RRC configuration signaling is equally applicable to Type1 and Type2 non-scheduled transmissions. For Type2 non-scheduled transmission, it is required that the DCI activation signaling informs the terminal that it can transmit according to pre-configured parameters, i.e. SPS (semi-persistent scheduling) transmission, in principle like LTE (long term evolution). Some of the information in the DCI may replace information in RRC configuration signaling, such as time domain resources, frequency domain resources, etc., i.e., the final configuration is determined by the DCI. And the terminal directly transmits on the determined time-frequency resource when uplink data are required to be transmitted after receiving the activation signaling according to the configuration.
That is, in the 5G system, the transmission delay of the air interface can be compressed by uplink scheduling-free transmission, so as to meet the transmission requirement of low delay. However, the resources of the non-scheduled transmission are semi-statically configured, for Type1 non-scheduled transmission, all transmission parameters are configured by high-layer signaling, for Type2 non-scheduled transmission, the transmission period is configured by high-layer signaling, and specific transmission parameters such as time-frequency domain resources are notified by DCI (downlink control information) activation signaling. Therefore, uplink scheduling-free transmission is performed, and once the uplink scheduling-free transmission is started, periodic transmission is performed on fixed time-frequency domain resources by adopting fixed transmission parameters. If the fixed parameters on the fixed resources are not suitable for uplink transmission due to factors such as channel condition change, environment change and the like, no mechanism is provided at present for informing the base station to reconfigure the uplink scheduling-free configuration.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
First, HARQ-ACK feedback involved in the embodiment of the present invention will be described.
When uplink scheduling-free transmission is performed, multiple terminals can share the same uplink scheduling-free resource in order to reduce system resource overhead. In the uplink scheduling-free transmission opportunity, if the terminal does not have uplink data to be transmitted, skip processing is performed, that is, the terminal does not transmit in the transmission opportunity, but on the base station side, blind detection, such as DMRS detection, needs to be performed because it is not known when the terminal has data to transmit, so as to determine whether there is data transmission and from which terminal the data transmission comes.
In R15 (release 15), the uplink non-scheduled transmission has no explicit ACK (acknowledgement) feedback, i.e. when the base station receives uplink data in the opportunity of the uplink non-scheduled transmission, if the reception is correct, the base station does not perform ACK feedback, if the reception is incorrect, the DCI scheduling terminal is sent for retransmission, and if no information is received, no feedback is performed. And the terminal side starts a timer when sending an uplink scheduling-free transmission, if the timer is finished and no DCI scheduling retransmission is received, the transmission is considered to be correct, and if the DCI scheduling retransmission is received, the corresponding retransmission is carried out. One disadvantage with this mechanism is that it is not possible to distinguish between ACK and DTX (discontinuous transmission), i.e. if the terminal performs an uplink transmission, but the base station side does not detect any transmission due to poor channel conditions, the base station does not perform any feedback, and at this time the terminal side decides that the transmission is correct as an ACK at the end of the timer, which would result in a loss of the data packet.
In R16 (release 16), an explicit HARQ-ACK (hybrid automatic repeat request-acknowledgement) feedback mechanism for uplink scheduling-free transmission is proposed to solve the above-mentioned problem that ACK and DTX in R15 cannot be distinguished. Under the explicit HARQ-ACK feedback mechanism, the terminal may be informed of the current reception result at the base station side by, for example, explicit ACK feedback or DTX feedback, so as to help the terminal confirm the transmission performance, i.e., whether false detection occurs at the base station side (i.e., the terminal does not send uplink transmission but the base station determines that information is received) or false detection does not occur (i.e., the terminal sends uplink transmission but the base station determines that information is not detected).
Based on the above mechanism, when the terminal judges that the base station is in a false detection or omission detection state for a long time, the current configuration of uplink scheduling-free transmission is not very suitable, and the base station needs to be informed to reconfigure uplink scheduling-free transmission so as to improve the transmission performance of uplink scheduling-free transmission. At present, no scheme for informing the base station to reconfigure uplink scheduling-free exists.
The invention provides an uplink scheduling-free configuration reconfiguration method which is applied to a terminal and aims at the problem that the uplink scheduling-free configuration cannot be reconfigured in the prior art, as shown in fig. 2, and comprises the following steps:
Step 21: determining whether a request for reconfiguration of uplink scheduling-free configuration needs to be sent;
step 22: and when the determination is yes, sending a request for reconfiguration of the uplink scheduling-free configuration.
The uplink scheduling-free configuration reconfiguration method provided by the embodiment of the invention determines whether a request for reconfiguration of uplink scheduling-free configuration needs to be sent or not; when the determination is yes, a request for reconfiguration of the uplink scheduling-free configuration is sent; when the original uplink scheduling-free transmission condition is not good, the base station is triggered to change the uplink scheduling-free configuration, so that the situation that the uplink scheduling-free transmission condition is always in a poor channel condition is avoided, and the uplink scheduling-free transmission performance is improved; the problem that uplink scheduling-free configuration cannot be reconfigured in the prior art is well solved.
Wherein the determining whether a request for reconfiguration of the uplink scheduling-free configuration needs to be sent includes: and determining whether a request for reconfiguration of the uplink scheduling-free configuration needs to be sent or not according to the uplink scheduling-free explicit hybrid automatic repeat request response (HARQ-ACK) feedback.
Specifically, the determining whether a request for reconfiguration of the uplink scheduling-free configuration needs to be sent according to the feedback of the uplink scheduling-free explicit hybrid automatic repeat request acknowledgement HARQ-ACK includes: when the terminal sends uplink transmission and the explicit HARQ-ACK of the uplink transmission is negative acknowledgement NACK or discontinuous transmission DTX, or when the continuous accumulated number of times of the explicit HARQ-ACK of the uplink transmission sent by the terminal is NACK or DTX reaches a preset value, determining that a request for reconfiguration of uplink scheduling-free configuration needs to be sent.
The following two exemplary schemes are provided in the embodiments of the present invention with respect to the transmission of the request:
the first method, the sending a request for reconfiguration of the uplink scheduling-free configuration, includes: transmitting a first uplink Scheduling Request (SR) through a Physical Uplink Control Channel (PUCCH); the first SR is a request for reconfiguration of the uplink scheduling-free configuration.

Wherein the first SR is one of a plurality of SR configurations pre-configured to the terminal.
The second method for sending the request for reconfiguration of the uplink scheduling-free configuration includes: the Buffer Status Report (BSR) of the Physical Uplink Shared Channel (PUSCH) carries a request for reconfiguration of uplink scheduling-free configuration.
Wherein, the PUSCH is a PUSCH scheduled with corresponding downlink control information DCI; or, PUSCH is PUSCH transmitted in the last uplink scheduling-free transmission opportunity after determining that a request for uplink scheduling-free reconfiguration needs to be transmitted.
The embodiment of the invention further comprises the following steps: and after determining that the request for reconfiguration of the uplink scheduling-free configuration needs to be sent and/or before the reconfiguration is completed, not sending uplink scheduling-free transmission of the corresponding uplink scheduling-free configuration.
The embodiment of the invention also provides an uplink scheduling-free configuration reconfiguration method which is applied to the base station, as shown in fig. 3, and comprises the following steps:
step 31: detecting a request for reconfiguration of uplink scheduling-free configuration;
step 32: and when the request is detected, the uplink scheduling-free configuration is reconfigured.
The uplink scheduling-free configuration reconfiguration method provided by the embodiment of the invention is implemented by detecting a request for reconfiguration of uplink scheduling-free configuration; when the request is detected, the uplink scheduling-free configuration is reconfigured; when the original uplink scheduling-free transmission condition is poor, the trigger of the terminal can be perceived, and the uplink scheduling-free configuration is changed, so that the situation that the uplink scheduling-free transmission is always in the poor transmission condition is avoided, and the uplink scheduling-free transmission performance is improved; the problem that uplink scheduling-free configuration cannot be reconfigured in the prior art is well solved.

Base station side:

And when the request is detected, reconfiguring the uplink scheduling-free.
The method for detecting the request for reconfiguring the uplink scheduling-free comprises the following steps:
mode 1: and receiving a first SR through the PUCCH, wherein the first SR is a request for reconfiguring uplink scheduling-free.
Specifically, receiving a positive SR on a PUCCH resource corresponding to the first SR; and/or the number of the groups of groups,
the first SR is one of a plurality of SR configurations pre-configured to the terminal; for example, an SR configuration with a minimum or maximum SR configuration number.
Mode 2: analyzing a request for reconfiguring uplink scheduling-free in a BSR of a PUSCH;
wherein, the PUSCH is a PUSCH with corresponding DCI scheduling, such as retransmission or dynamically scheduled PUSCH; or alternatively
And the PUSCH is the PUSCH which is transmitted in the last uplink scheduling-free transmission opportunity after determining that the request for uplink scheduling-free reconfiguration needs to be transmitted.
Further, the method further comprises the following steps:
after the request is detected and/or before the reconfiguration is completed, uplink scheduling-free transmission corresponding to the uplink scheduling-free configuration is not received; and/or the number of the groups of groups,
for Type2 no-scheduling, the no-scheduling configuration may be changed by retransmitting the activation DCI, or may be changed by RRC reconfiguration.
The uplink scheduling-free configuration reconfiguration method provided by the embodiment of the invention is illustrated below.
Suppose that the base station configures Type1 non-scheduled transmission through higher layer signaling, and its transmission opportunity is shown in fig. 4 and 5. Assume that the terminal is configured with 2 SR configurations, where SR configuration 1 is pre-agreed or configured for a request for uplink scheduling-free reconfiguration, i.e. the first SR, SR configuration 2 is a normal uplink scheduling request.
Case 1: the terminal sends a PUSCH (physical uplink shared channel) in the uplink scheduling-free transmission opportunity in the time slot n, and when the explicit HARQ-ACK feedback information of the PUSCH is received as DTX in the time slot n+1, the terminal judges that the current channel condition is not good, and needs to inform a base station to perform uplink scheduling-free reconfiguration; as shown in fig. 4 and 5.
Case 2: the terminal sends a PUSCH in an uplink scheduling-free transmission opportunity in a time slot n, explicit HARQ-ACK feedback information of the PUSCH is received in a time slot n+1 and is DTX, and so on, the feedback information of the PUSCH sent by the terminal in the time slots n, n+2, n+4 and n+6 is DTX, namely continuous 4 times of DTX feedback is achieved, the terminal judges that the current channel condition is poor, and the terminal needs to be informed to inform a base station to reconfigure uplink scheduling-free; as shown in fig. 6 and 7;
For the above cases 1 and 2, the terminal side:
mode 1: transmitting a positive SR on a PUCCH (physical uplink control channel) resource corresponding to the SR configuration, and informing a base station to reconfigure uplink scheduling-free; for case 1, as shown in fig. 4, for case 2, as shown in fig. 6;
mode 2: the method comprises the steps that indication information for reconfiguring uplink scheduling-free is carried in a last PUSCH with corresponding DCI through BSR carrying indication;
in the above manner, the terminal may not perform PUSCH transmission in the subsequent transmission opportunity until completing the scheduling-free reconfiguration, and then perform scheduling-free transmission according to the new configuration; for case 1, as shown in fig. 5, for case 2, as shown in fig. 7;
base station side:
mode 1: detecting a positive SR on a PUCCH resource corresponding to the SR configuration, and determining that the uplink scheduling-free reconfiguration is required when the detection is yes; subsequently searching proper downlink transmission opportunity to send reconfiguration information;
mode 2: BSR detection in subsequent PUSCH transmission determines whether there is indication information indicating that uplink scheduling is to be reconfigured, and when the indication information is received, determines that uplink scheduling is to be reconfigured; subsequently searching proper downlink transmission opportunity to send reconfiguration information;
In the above manner, the base station may not perform PUSCH reception on the terminal in the subsequent transmission opportunity until completing the scheduling-free reconfiguration, and then perform scheduling-free reception on the terminal according to the new configuration; of course, if there are multiple terminals sharing the uplink non-scheduling configuration, the base station also needs to receive non-scheduling transmissions of other terminals corresponding to the uplink non-scheduling configuration.
It should be noted that: in the above example, if the Type1 non-scheduling is replaced by the Type2 non-scheduling, the method is applicable, but only the DCI activating the Type2 non-scheduling transmission needs to be received before the whole example process, and the process is executed after the DCI activating; after receiving the uplink scheduling-free reconfiguration request, the base station can select to retransmit the activated DCI once, and change the Type2 scheduling-free transmission parameters, such as time domain resources, frequency domain resources, modulation and coding strategy MCS, etc., by activating the DCI, or can select to reconfigure from the RRC layer, where the parameters including the period, etc. are changed.
In the above example, the received explicit feedback information is taken as DTX as an example, and it is naturally also applicable to replace DTX with NACK if it is predefined that the received display feedback information is NACK to trigger uplink operation.
As can be seen from the foregoing, the scheme provided by the embodiment of the present invention may be specifically a method for enabling a base station to reconfigure uplink scheduling-free by sending an uplink scheduling-free reconfiguration request; when the original uplink scheduling-free transmission condition is not good, the base station is triggered to change the uplink scheduling-free configuration, so that the situation that the uplink scheduling-free transmission condition is always in the poor channel condition is avoided, and the uplink scheduling-free transmission performance is improved.
The embodiment of the invention also provides a terminal which comprises a memory, a processor, a transceiver and a computer program which is stored in the memory and can run on the processor; the processor, when executing the program, performs the steps of:
