Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
The embodiment of the invention provides a monitoring control method, which is applied to a terminal, wherein the terminal is a device capable of communicating. As shown in fig. 1, the method includes:
step 101, receiving a demodulation result of the PUSCH data issued by the base station.
The demodulation results in this embodiment are generated in two different cases.
The first case is a normal case, when the demodulation result is ACK, the demodulation result indicates that the reception is successful; when the demodulation result is NACK, the demodulation result indicates reception failure.
The second case is that there is an abnormal situation, that is, the base station should demodulate NACK, and due to various reasons, there is a case that ACK is not ready to be delivered, and at this time, ACK and NACK cannot completely indicate whether the reception is successful. Therefore, when the demodulation result is ACK, two cases need to be considered. When the demodulation result is ACK and the indication information of the base station indicates that the current base station does not transmit data with the terminal, the demodulation result indicates that the receiving is successful (the ACK is considered to be ACK); when the demodulation result is ACK and the indication information of the base station indicates that the current base station and the terminal transmit data, the demodulation result indicates reception failure (ACK is considered to be false ACK).
And 102, stopping monitoring the PDCCH when the demodulation result shows that the receiving is successful.
Specifically, the buffer data of the HARQ is cleared, and a Discontinuous Reception (DRX) sleep state is entered.
Further, the indication information includes a first state whether the current terminal sends data to the base station and a second state whether the current base station sends data to the terminal. Here, the base station itself can control whether it is to continue to transmit data to the terminal, but the base station cannot control the terminal to transmit data. Therefore, the first state may be a state in which the terminal periodically replies with whether to send data to the base station, or a state in which the base station maintains a first BSR indicating whether the terminal sends data to the base station (i.e., uplink to the terminal). Preferably, the first state is a first BSR state of the current terminal uplink. Wherein, the first BSR state is 0, which indicates that the terminal does not transmit data to the base station; the first BSR state is non-0, indicating that the terminal transmits data to the base station. Similarly, the second state may be a state in which the base station periodically acquires whether to transmit data to the terminal, or a state in which a second BSR indicating whether the base station transmits data to the terminal (i.e., downlink of the base station) is maintained. Preferably, the second state is a second BSR state of the current base station downlink. Wherein, the second BSR state is 0, which indicates that the base station does not transmit data to the terminal; the second BSR state is non-0, which indicates that the base station transmits data to the terminal.
Therefore, when the demodulation result indicates that the reception is successful, which indicates that the base station has already scheduled the BSR of the terminal, the base station does not schedule the terminal, and therefore, the terminal stops monitoring the PDCCH channel, and thus, the terminal does not monitor the PDCCH channel any more, thereby saving the electric quantity wasted during the monitoring.
It should be noted that, as the enhanced PHICH channel technology has been discussed in the current Release12 (Release12, R12) protocol, an enhanced PHICH channel can be designed, and redundant 1-bit information is added to the enhanced PHICH channel, and the information is the above-mentioned indication information.
Further, when the demodulation result indicates that the reception is failed, or when the demodulation result indicates that the reception is successful and the indication information indicates that the current terminal and the base station transmit data, the PDCCH channel continues to be monitored.
Further, before step 101, the method further comprises: receiving DCI0 information issued by the base station; receiving PUSCH data issued by the base station; and demodulating PUSCH data to obtain the demodulation result.
Example two
The embodiment of the invention provides a monitoring control method, which is applied to a base station, wherein the base station is a device capable of communicating. As shown in fig. 2, the method includes:
step 201, receiving PUSCH data transmitted by a terminal.
Step 202, the PUSCH data is demodulated to obtain a demodulation result indicating reception success or failure.
Step 203, the demodulation result is sent to the terminal.
Therefore, when the demodulation result indicates that the reception is successful, which indicates that the base station has completed the scheduling, the base station does not schedule the terminal, and therefore, the terminal stops monitoring the PDCCH channel, and thus, the terminal does not monitor the PDCCH channel any more, thereby saving the electric quantity wasted during the monitoring.
Further, when the demodulation result is ACK, the demodulation result indicates that the reception is successful; when the demodulation result is NACK, the demodulation result indicates reception failure.
Further, step 202 may specifically include: demodulating PUSCH data to obtain the demodulation result; when the demodulation result is ACK, acquiring indication information, wherein the indication information indicates whether the current base station performs data transmission with the terminal; when the indication information indicates that the current base station does not perform data transmission with the terminal, the demodulation result indicates that the reception is successful (the ACK is considered to be a true ACK); when the indication information indicates that the current base station and the terminal perform data transmission, the demodulation result indicates that the reception fails (the ACK is considered as a false ACK).
Further, the indication information includes a first state of whether the terminal transmits data to the base station and a second state of whether the base station transmits data to the terminal.
Here, the first state is a first BSR state maintaining whether the terminal transmits data to the base station; the second state is a second BSR state for maintaining whether the base station sends data to the terminal; wherein, the first BSR state is 0, which indicates that the terminal does not transmit data to the base station; the first BSR state is non-0 and represents that the terminal sends data to the base station; the second BSR state is 0, which indicates that the base station does not transmit data to the terminal; the second BSR state is non-0, which indicates that the base station transmits data to all base station terminals.

Step 302, the user equipment uploads PUSCH data to the base station in radio frame No. 0 and subframe No. 4.
And step 303, the base station demodulates the PUSCH data to obtain ACK.
And step 304, the base station acquires the indication information.
Here, the indication information includes a first state indicating whether the base station transmits data to the user equipment (i.e., a first BSR state of the base station downlink) and a second state indicating whether the user equipment transmits data to the base station (i.e., a second BSR state of the user equipment uplink).
Step 305, when the indication information indicates that the current base station and the user equipment do not perform data transmission with the user equipment, the base station determines that the ACK is a true ACK.
Step 306, the base station sends the demodulation result indicating that the ACK is true ACK to the user equipment in the No. 0 wireless frame No. 8 subframe.
And 307, emptying the data of the buffer area of the current HARQ, entering a DRX sleep state, and finishing the process.
Step 308, the base station demodulates the PUSCH data to obtain NACK.
Step 309, the base station issues NACK to the ue on subframe No. 8 of radio frame No. 0.
Step 310, the ue continues to monitor the PDCCH channel in radio frame No. 0 and subframe No. 8.
It should be noted that the above steps 301 to 307 can also be shown in the schematic diagram of fig. 4-a; steps 301, 302 and 308 to 310 may likewise be illustrated in the schematic diagram of fig. 4-b. The embodiment is performed by taking the following behavior example of the base station
Example four

As shown in fig. 5, the method may include:
step 401, the base station MAC sends a new DCI0 message to the user equipment in radio frame No. 0 and subframe No. 3;
step 402, the user equipment uploads PUSCH data to the base station in sub-frame No. 7 of radio frame No. 0.
Step 403, the base station demodulates the PUSCH data to obtain ACK.
And step 404, the base station acquires the indication information.
Here, the indication information includes a first state indicating whether the base station transmits data to the user equipment (i.e., a first BSR state of the base station downlink) and a second state indicating whether the user equipment transmits data to the base station (i.e., a second BSR state of the user equipment uplink).
Step 405, when the indication information indicates that the current base station and the user equipment perform data transmission with the user equipment, the base station determines that the ACK is a false ACK.
Here, the data transmission between the base station and the user equipment includes the data transmission between the base station and the user equipment and/or the data transmission between the user equipment and the base station.
Step 406, the base station issues a demodulation result indicating that the ACK is a false ACK to the user equipment in the number 1 radio frame number 3 subframe.
