Description

The present invention belongs to the field of communication technology, and in particular relates to a scheduling request SR transmission method and related equipment.

In the LTE (Long Term Evolution) system, the period of SR (Scheduling Request) is defined in units of subframes, and the minimum transmission period of SR is 1 subframe. Each SR transmission It is carried out according to one sub-frame, that is, TTI (Transmission Time Interval, transmission time interval) = 1ms (milliseconds). SR is only used to schedule the PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) for 1ms transmission. .

In a system that reduces latency, a TTI shorter than a subframe can be defined for uplink transmission, that is, PUSCH transmission of 1ms and shorter than 1ms is supported. Therefore, the terminal needs to feedback SR for PUSCH scheduling requests with different TTI lengths. In addition, the SR transmission cycle can also be less than 1ms, thereby supporting faster SR feedback.

Therefore, the SR feedback mechanism in traditional systems is no longer applicable. Currently, there is no technical solution for SR feedback for terminals that support different transmission time intervals.

In the embodiment of the present invention, step 101 is first performed: the terminal obtains the first physical uplink control channel PUCCH resource corresponding to the first SR and the second PUCCH resource corresponding to the second SR.

In step 101, the first SR corresponds to the first uplink shared channel or the first service transmitted using the first TTI length, and the second SR corresponds to the second uplink shared channel or the second service transmitted using the second TTI length. ;or, The first SR corresponds to the first service, the second SR corresponds to the second service, and the service attributes of the first service and the second service are different; or, The transmission period and/or offset value of the first SR are configured based on the first TTI length, and the transmission period and/or offset value of the second SR are configured based on the second TTI length.

For example, if the first TTI length is 7 symbols, then the second TTI length is 2 symbols or 4 symbols. In the embodiment of the present invention, the symbols may be SC-FDMA (Single-Carrier Frequency-Division Multiple Access, single carrier frequency division multiple access) symbols, or OFDM (Orthogonal Frequency Divisong Multiplexing, orthogonal frequency division multiplexing) symbols. or other symbols, which are not specifically limited in the embodiment of the present invention.

After step 101 is executed, step 102 is executed: the terminal determines whether the first SR and/or the second SR needs to be transmitted.

In the embodiment of the present invention, the length of the first TTI is 1 ms and the length of the second TTI is 7 symbols (one time slot). The first SR can configure the period and offset value in units of subframes to determine the first SR. The transmission opportunities of an SR are shown in Figure 2A-Figure 2C, that is, subframes #i, i+2, i+4... are the first SR transmission subframes, and the first SR can transmit 1 every two subframes.

The second type The terminal determines whether it needs to transmit the second SR during the transmission opportunity of the second SR.

In the specific implementation process, the transmission opportunity of the second SR is determined according to the transmission period and/or offset value of the second SR, such as: time slot #j, j+2, j+4..., in each second SR Determine whether the second SR needs to be transmitted in the transmission opportunity, that is, determine whether it is necessary to make a scheduling request for the second uplink shared channel or the second service in the transmission opportunity of each second SR. If so, determine that there is a second SR that needs to be transmitted. , otherwise it is determined that there is no second SR that needs to be transmitted.

In this embodiment of the present invention, when the first SR transmission opportunity is determined based on the transmission period and/or offset value of the first SR and the second transmission opportunity is determined based on the transmission period and/or offset value of the second SR, they may overlap, For example: subframe #i and time slot #j, subframe i+2 and time slot j+4. In this case, the terminal needs to determine whether to transmit the first SR and the second SR at the same time, that is, determine whether to transmit the first uplink shared channel or the first service and the second uplink shared channel or the third SR at each coincidence opportunity. The second service performs a scheduling request. If necessary, it is determined that the first SR and the second SR need to be transmitted. Otherwise, it is determined that there is no first SR and the second SR that need to be transmitted.

In the embodiment of the present invention, after step 102 is executed, step 103 is executed: if the first SR and/or the second SR needs to be transmitted, the terminal transmits the first SR and/or the second SR through the PUCCH. SR.

After step 301 is executed, step 302 is executed: the network side device detects whether the first SR and/or the second SR transmitted by the terminal is received.

In the embodiment of the present invention, the specific implementation process of step 302 includes but is not limited to the following implementation methods, which are described below.

The first type The network side device detects the first SR on the first PUCCH resource in the transmission opportunity of the first SR.

In a specific implementation process, the network side device detects the first SR on the first PUCCH resource corresponding to the first SR in the transmission opportunity of the first SR.

The second kind The network side device detects the second SR on the second PUCCH resource in the transmission opportunity of the second SR.

In the embodiment of the present invention, in the transmission opportunity of the second SR, such as: in the first time slot (time slot #j+2) in subframe #i+1, the network side device only transmits the second SR. For SR transmission opportunities, the network side device detects the PUCCH resource 2 corresponding to the second SR. If detected, the terminal is considered to have sent the second SR, and the uplink shared channel or service transmission corresponding to the second SR is scheduled for the terminal. If it is not detected, it means that the terminal did not send the second SR.

In the embodiment of the present invention, when the transmission opportunities of the first SR and the second SR overlap, such as: in the first time slot (time slot #j) in subframe #i, or in subframe i The first time slot of +2 (time slot j+4) is a transmission opportunity for the first SR and the second SR at the same time; because the network side device does not know that the terminal currently has the first SR and the second SR that need to be transmitted at the same time. There are two SRs, there is only one of them that needs to be transmitted, or there is no SR that needs to be transmitted. The network side device can only perform blind detection on the PUCCH resources corresponding to the first SR and the second SR.

If detected, the terminal is considered to have sent the second SR, and the uplink shared channel or service transmission corresponding to the second SR is scheduled for the terminal. If If not detected, it means that the terminal did not send the second SR. At this time, it can be further detected on the PUCCH resource 1 corresponding to the first SR. If detected, the terminal is considered to have sent the first SR, and the first SR will be scheduled for the terminal.

If there is no detection, , it means that the terminal did not send the second SR, and can further detect it on the PUCCH resource 1 corresponding to the first SR. If detected, the terminal is considered to have sent the first SR, and the uplink sharing corresponding to the first SR is scheduled for the terminal. If channel or service transmission is not detected, it means that the terminal did not send the first SR.

The third type uses the third type of method for the terminal to transmit the first SR and the second SR. The network side device can perform blind detection on the PUCCH resources corresponding to the first SR and the second SR at the same time. On which SR resource the information is detected, it is considered which SR the terminal sent, and the uplink shared channel corresponding to the SR is scheduled for the terminal. or business transmission; In the above methods 1 to 3, when the network side device detects on the PUCCH resource 1 corresponding to the first SR, it can detect based on the PUCCH transmitted using the first TTI length, or it can detect based on the PUCCH transmitted using the second TTI length. , depending on which length of PUCCH is used for transmission by the pre-agreed or configured first SR, correspondingly, when configuring PUCCH resource 1, it is also configured for the PUCCH of the corresponding length.
