Description
Technical Field
The present invention relates to a Discontinuous Reception (DRX) technology, and in particular, to a method and a terminal for implementing DRX.
Background
In a Long Term Evolution (LTE) system, DRX technology is generally used to save power for a terminal. In this way, the terminal may periodically monitor a Physical Downlink Control Channel (PDCCH) according to the configuration. For some specific processes, such as receiving a new transmission schedule, a downlink retransmission, an uplink retransmission, a non-collision random access downlink data waiting, a collision resolution, and a Scheduling Request (SR), the terminal needs to continuously detect the PDCCH for a period of time outside the DRX cycle, that is, the terminal needs to detect the PDCCH during the active time (active time) of the DRX, in other words, the above processes all belong to the DRX active time of the terminal. Thus, according to several specific procedures and configurations of DRX described above, irregular DRX activation times are formed as shown in fig. 1.
With the rapid growth of data services, the licensed spectrum resources cannot bear such a huge amount of data, so it is necessary in the LTE system to share the data traffic in the licensed carriers through the unlicensed carriers. The unlicensed carrier and the licensed carrier can be used in a carrier aggregation manner, and can also be used in a dual connectivity manner. The unlicensed carrier is generally used as a complement to data transmission, that is, the licensed carrier serves as a primary serving Cell (Pcell) and the unlicensed carrier serves as a Secondary serving Cell (Scell). Moreover, the unlicensed carrier needs to be used by contention, and if the base station (including the WiFi access point) does not contend for the resource, the unlicensed carrier cannot be used, that is, the available resource of the unlicensed carrier is discontinuous.
Therefore, due to the discontinuity of available resources of the unlicensed carrier, after the unlicensed carrier is introduced in the LTE system, there is no effective solution for how the terminal implements DRX.

step S704: and when the available resources are not contended again at the end time of the waiting contention resource timer, directly stopping the DRX retransmission timer.
In an embodiment of the present invention, as shown in fig. 8, the performing DRX operation in combination with the current state of the terminal itself and the start-stop time includes:
step S801: when the uplink retransmission starts after the starting time;
step S802: after the termination time is reached, if the uplink retransmission process is still in progress, starting a contention waiting resource timer;
step S803: when the available resources are contended again at the end time of the waiting contention resource timer, stopping the uplink retransmission process after the stop time corresponding to the uplink retransmission process is reached;
step S804: and when the available resources are not contended again at the end time of the waiting contention resource timer, directly stopping the uplink retransmission process.
In an embodiment of the present invention, as shown in fig. 9, the performing DRX operation in combination with the current state of the terminal itself and the start-stop time includes:
step S901: when the execution of the non-collision random access process is successful after the starting time, starting to wait for a first scheduling process;
step S902: and finishing waiting the first scheduling process or finishing the activation time after the termination time is reached.
Here, when the terminal starts to wait for the first tuning process, since the DRX is in an active state, the terminal starts to monitor the PDCCH of the available resource at the same time; and then, when the waiting for the first scheduling process is finished or the activation time is terminated, the terminal stops monitoring the PDCCH of the available resources at the same time as the DRX is in the deactivation state.
Therefore, the terminal can effectively realize the DRX under the condition that an unauthorized carrier is introduced into an LTE system by the method for realizing the DRX, thereby achieving the purpose of saving electricity.

The method for implementing DRX according to the embodiment of the present invention is further described in detail below with reference to specific application examples.
In the following application example, the base station includes three cells, which are a primary serving cell 1 and a secondary serving cell 3 and a cell 4, respectively, that is, the cell 1 is a licensed carrier, and the cell 3 and the cell 4 are unlicensed carriers. Firstly, a terminal establishes a connection with a cell 1, and then a base station performs DRX configuration for the terminal, which specifically includes: an on Duration Timer, a DRX Inactivity Timer, a DRX Retransmission Timer, and related configurations corresponding to the long DRX and the short DRX, respectively, such as cycle, offset, short DRX Timer, etc.
Application example one:
step A1: as the traffic increases, the base station adds cell 3 to the terminal based on the measurement report. Since the cell 3 is an unlicensed carrier, the resource usage right needs to be acquired in a contention mode, and the terminal is configured with the DRX of the cell 3, the DRX configuration of the cell 3 may be the same as that of the cell 1 (at this time, the terminal does not need to be configured again), or may be configured separately.
Step B1: and the terminal adds the cell 3 after receiving the configuration information of the cell 3 and starts to apply the DRX configuration of the cell 3.
Step C1: the base station initiates a resource competition process of the cell 3 according to the requirement of the terminal traffic.
Step D1: after the base station contends for the resources of the cell 3, the time from T1 to T3 in fig. 11 is the available resources, the terminal starts to schedule data transmission and reception in the cell 3, and notifies the terminal through a specified signaling, such as a higher layer signaling or a lower layer signaling, where T1 and T3 are the start time and the end time corresponding to the available resources of the cell 3, respectively.
Step E1: the terminal receives the newly transmitted schedule of the cell 3 at time T2, starts monitoring the PDCCH of the cell 3, and starts the DRX prohibiting timer.
Here, if the duration of the DRX timer needs to be terminated at time T4 according to the duration of the DRX timer.
Step F1: after knowing the time T3 according to the designated signaling, the terminal cannot use the resources of the cell 3, and therefore, at the time T3, the terminal stops monitoring the PDCCH of the cell 3 by stopping the DRX timer.
Application example two:
step A2: the traffic increases and the base station adds cell 3 to the terminal according to the measurement report. Since the cell 3 is an unlicensed carrier, the resource usage right needs to be acquired in a contention mode, and the terminal is configured with the DRX of the cell 3, the DRX configuration of the cell 3 may be the same as that of the cell 1 (at this time, the terminal does not need to be configured again), or may be configured separately.
Step B2: and the terminal adds the cell 3 after receiving the configuration information of the cell 3 and starts to apply the DRX configuration of the cell 3.
Step C2: the base station initiates a resource competition process of the cell 3 according to the requirement of the terminal traffic.
Step D2: after the base station contends for the resources of the cell 3, the time from T1 to T3 in fig. 12 is the available resources, the terminal starts to schedule data transmission and reception in the cell 3, and notifies the terminal through a specified signaling, such as a higher layer signaling or a lower layer signaling, where T1 and T3 are the start time and the end time corresponding to the available resources of the cell 3, respectively.
Step E2: at time T2, the terminal starts monitoring the PDCCH of cell 3 and starts the DRX retransmission timer when the round trip time timer RTT timer expires.
Here, if the duration of the DRX retransmission timer needs to be ended at time T4.
Step F2: since the terminal knows that the resources of the cell 3 cannot be used at the time T3 according to the designated signaling, the terminal stops monitoring the PDCCH of the cell 3 at the time T3 by stopping the retransmission timer.
Application example three:
step A3: the traffic increases and the base station adds cell 3 to the terminal according to the measurement report. Since the cell 3 is an unlicensed carrier, the resource usage right needs to be acquired in a contention mode, and the terminal is configured with the DRX of the cell 3, the DRX configuration of the cell 3 may be the same as that of the cell 1 (at this time, the terminal does not need to be configured again), or may be configured separately.
Step B3: and the terminal adds the cell 3 after receiving the configuration information of the cell 3 and starts to apply the DRX configuration of the cell 3.
Step C3: the base station initiates a resource competition process of the cell 3 according to the requirement of the terminal traffic.
Step D3: after the base station contends for the resources of the cell 3, the time from T1 to T3 in fig. 13 is the available resources, the terminal starts to schedule data transmission and reception in the cell 3, and notifies the terminal through a specified signaling, such as a higher layer signaling or a lower layer signaling, where T1 and T3 are the start time and the end time corresponding to the available resources of the cell 3, respectively.
Step E3: and at the time of T2, the terminal starts uplink retransmission, the terminal starts monitoring the PDCCH of the cell 3, and if retransmission is always needed, the retransmission process is finished at the time of T4 after the maximum retransmission times.
Step F3: after the terminal knows the time T3 according to the designated signaling, the resource of the cell 3 cannot be used, so at the time T3, the uplink retransmission process is ended, the terminal stops monitoring the PDCCH of the cell 3, and the number of times that the terminal has currently sent is modified to the maximum retransmission number-1, or the buffer area needing to be retransmitted is directly cleared.
Application example four:
step A4: the traffic increases and the base station adds cell 3 to the terminal according to the measurement report. Since the cell 3 is an unlicensed carrier, the resource usage right needs to be acquired in a contention mode, and the terminal is configured with the DRX of the cell 3, the DRX configuration of the cell 3 may be the same as that of the cell 1 (at this time, the terminal does not need to be configured again), or may be configured separately.
Step B4: and the terminal adds the cell 3 after receiving the configuration information of the cell 3 and starts to apply the DRX configuration of the cell 3.
Step C4: the base station initiates a resource competition process of the cell 3 according to the requirement of the terminal traffic.
Step D4: after the base station contends for the resources of the cell 3, the time from T1 to T3 in fig. 14 is the available resources, the terminal starts to schedule data transmission and reception in the cell 3, and notifies the terminal through a specified signaling, such as a higher layer signaling or a lower layer signaling, where T1 and T3 are the start time and the end time corresponding to the available resources of the cell 3, respectively.
Step E4: the terminal successfully executes non-collision random access at the time of T2, starts to wait for the first scheduling, and starts to monitor the PDCCH of the cell 3;
step F4: since the terminal knows that the resources of the cell 3 cannot be used at the time T3 according to the designated signaling, the terminal ends waiting at the time T3 and stops monitoring the PDCCH of the cell 3.
Application example five:
step A5: the traffic increases and the base station adds cell 3 to the terminal according to the measurement report. Since the cell 3 is an unlicensed carrier, the resource usage right needs to be acquired in a contention mode, and the terminal is configured with the DRX of the cell 3, the DRX configuration of the cell 3 may be the same as that of the cell 1 (at this time, the terminal does not need to be configured again), or may be configured separately.
Step B5: and the terminal adds the cell 3 after receiving the configuration information of the cell 3 and starts to apply the DRX configuration of the cell 3.
Step C5: the base station initiates a resource competition process of the cell 3 according to the requirement of the terminal traffic.
Step D5: after the base station contends for the resources of the cell 3, the time from T1 to T3 in fig. 15 is the available resources, the terminal starts to schedule data transmission and reception in the cell 3, and notifies the terminal through a specified signaling, such as a higher layer signaling or a lower layer signaling, where T1 and T3 are the start time and the end time corresponding to the available resources of the cell 3, respectively.
Step E5: the terminal receives the newly transmitted scheduling of the cell 3 at the time of T2, starts monitoring the PDCCH of the cell 3, starts the DRX prohibiting timer, ends at the time of T4 according to the time length of the timer, ends at the time of T3 the resource contended on the cell 3, and at this time, the DRX prohibiting timer is still running, so the contention waiting resource timer is started, and ends at the time of T3' after the set time.
Step F5: as shown in fig. 15, in the case of the unlicensed carrier contention condition 1, when the time T3' is over, and the cell 3 re-contends for the resource, the DRX prohibition timer is not processed, and the time T4 is over according to the original configuration, that is, the DRX prohibition timer is stopped to T4.
Step G5: in the unlicensed carrier contention scenario 2 shown in fig. 15, the time T3 'is over, the cell 3 does not contend for the resource again, the DRX timer is stopped, and the DRX time is prohibited to T3'.
In the above embodiment, the resource contention process of the cell 3 may be completed by the base station itself or the terminal requests the base station to complete, or completed by the terminal itself or completed by the terminal receiving the request of the base station, which is not limited.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
