Technical Field

Background

In a wireless communication system, when a terminal receives downlink data transmission in a DRX mode, there are a first timer and a second timer. The first timer is started after the terminal sends the HARQ-ACK signal fed back by the PDSCH, and after the first timer is overtime, if the UE fails to decode the PDSCH, the terminal equipment monitors the PDCCH during the working period of the second timer to acquire the downlink retransmission scheduling.

In the base station energy saving operation mode, the base station is brought into active and inactive states. When the inactive receiving period of the base station collides with the period in which the terminal side device transmits the HARQ signal, or the inactive transmitting period of the base station collides with the period in which the terminal side device receives the downlink PDCCH, the terminal device may fail to receive the PDCCH for retransmission.

Or further, in one embodiment of the present application, in response to the failure of receiving the downlink signal information, the second timer working interval overlaps with the inactive transmission time, and the second timer is restarted after the inactive transmission time ends to receive the downlink signal information.

In any one embodiment of the present application, the uplink information includes HARQ information fed back to the target PDSCH, and the downlink information includes retransmission scheduling information of the target PDSCH.

The application solves two specific problems which can occur according to the existing terminal behaviors when the base station inactivity time period and the terminal activity time period overlap, one problem is that if the terminal does not send the uplink HARQ when the terminal uplink HARQ overlaps with the base station discontinuously received inactivity time period, the terminal will not start the first timer according to the existing terminal behaviors, meanwhile, as the first timer is the front timer of the second timer, the second timer is not started, and if the duration timer and the inactivity timer are not running, the terminal can not receive the PDCCH for retransmission.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Fig. 1 is a prior art terminal side operation sequence of a DRX mode of a wireless communication system. Regarding discontinuous reception mode (DRX), the function of the DRX parameter HARQ discontinuous operation mode first timer (i.e. Drx HARQ RTT Timer DL) in NR C-DRX is that when the terminal receives downlink control channel indicating downlink data transmission, the terminal receives downlink data and performs uplink HARQ feedback on the received data, and starts the first timer for the corresponding HARQ process on the first symbol after sending the uplink HARQ feedback, because for the same HARQ process, when one uplink scheduling or downlink scheduling, a certain processing time is required until the next scheduling, this time is called HARQ RTT time, after the DRX function is turned on, this time needs to be configured, and for the same HARQ process, scheduling of PDCCH is not possible.

For the same HARQ process in downlink, if the UE fails to decode the PDSCH, after the first timer is overtime, the UE must monitor the PDCCH to acquire the DL retransmission schedule, and then the UE starts the downlink retransmission timer to wait for the downlink retransmission schedule. If the first timer expires: if the data of the corresponding HARQ process is not successfully decoded, a discontinuous operation mode second timer (i.e. Retransmission Timer DL) of the corresponding HARQ process is started in a first symbol after the expiration of the first timer, and when the second timer is running, the UE is regarded as being in an active time, and the terminal is in an inactive time after the end of the timer.

Fig. 2 is a diagram illustrating a terminal side uplink information collision of a DRX mode of a base station power saving operation mechanism. Because the base station energy conservation introduces active and inactive states, if the terminal performs uplink HARQ feedback and the inactive receiving period of the base station is just overlapped, the terminal cannot send the HARQ feedback, and the first timer cannot be started.

Fig. 3 is a diagram illustrating a terminal-side downlink information collision of a DRX mode of a base station power saving operation mechanism. Since the base station power saving introduces active and inactive states, if the second timer duration overlaps with the inactive transmission period of Cell DTX, the UE may not receive the PDCCH for retransmission.

Fig. 4 is a flowchart of an embodiment of the method for resolving uplink information collision according to the present application. The method of any one embodiment of the first aspect of the present application, for a terminal device, includes steps 110 to 140 for resolving uplink information collision:

step 110, determining the inactive receiving time and/or the inactive sending time of the base station according to the downlink signaling.

For example, the terminal receives the inactive reception and inactive transmission time of the base station first downlink signaling indication base station, or the inactive reception time of the base station second downlink signaling indication base station, and the inactive transmission time of the base station third downlink signaling indication base station.

Mode 1: the terminal receives a first downlink signaling, wherein the first downlink signaling is a semi-statically configured high-layer RRC signaling or MAC layer signaling, the signaling information indicates a period of inactive reception to a terminal base station, and the indication information comprises a starting time of the inactive reception and a period of the inactive reception and is used for judging the period of the inactive reception of the base station by the terminal; the first downlink signaling also indicates a period of inactive transmission to the terminal base station, and the indication information includes a start time of the inactive transmission and a period of the inactive transmission.

Mode 2: the terminal receives a second downlink signaling, wherein the second downlink signaling is dynamic signaling indicated by a downlink control signaling, signaling information indicates a duration of inactive reception of a base station of the terminal, the terminal receives a third downlink signaling for an inactive reception period of the base station within the indicated duration after receiving the second downlink signaling, the third downlink signaling is dynamic information indicated by the downlink control signaling, the signaling information indicates a duration of inactive transmission of the base station of the terminal, and the terminal receives an inactive transmission period of the base station within the indicated duration after receiving the third downlink signaling.

Step 120, receiving PDCCH and PDSCH scheduled by PDCCH.

And receiving the target PDSCH, and generating uplink information, wherein the uplink information is terminal uplink HARQ information and comprises HARQ information fed back to the target PDSCH. It can be understood that ACK is transmitted if decoding is successful and NACK is transmitted if decoding is unsuccessful according to the target PDSCH position indicated by PDCCH.

And 130, starting a first timer at a preset uplink information transmission ending time in response to the preset uplink information transmission time overlapping with the inactive receiving time.

And the terminal transmits the uplink information and conflicts with the non-active time period of discontinuous reception of the base station, the terminal does not transmit the uplink information, and the terminal starts a first timer at a first symbol after the preset time for transmitting the uplink information is ended.

For example, the uplink information is uplink HARQ information, if the uplink HARQ feedback timing of the terminal overlaps with the inactive period of discontinuous reception of the base station, the terminal does not transmit HARQ feedback, and the terminal starts Drx HARQ RTT Timer DL in the first symbol after the HARQ feedback timing for transmitting HARQ feedback ends, thereby ensuring that the terminal can normally start the second timer to start, and ensuring that the terminal can receive the PDCCH for retransmission as soon as possible.

Step 140, in response to the first timer being timed out, starting a second timer; and receiving downlink information in the second timer working area.

Step 140 is performed under the condition that the target PDSCH decoding fails. The downlink information includes retransmission scheduling information of the target PDSCH.

The first timer is a pre-timer of the second timer, that is, the second timer is started after the first timer expires (or when a timing duration is reached), for example, the second timer is started in the first symbol after the expiration of the first timer.

Fig. 5 is a flowchart of an embodiment of the method for resolving downlink information collision according to the present application. The method of any one embodiment of the first aspect of the present application, for a terminal device, includes steps 210 to 240 for resolving downlink information conflicts:

step 210, determining the inactive receiving time and/or the inactive transmitting time of the base station according to the downlink signaling (step 110).

For example, in the same step 101, the terminal receives the inactive reception and inactive transmission time of the base station first downlink signaling indication base station, or the inactive reception time of the base station second downlink signaling indication base station, and the inactive transmission time of the base station third downlink signaling indication base station.

Step 220, the PDCCH and the scheduled PDSCH are received (step 120).

And receiving the target PDSCH, and generating uplink information, wherein the uplink information comprises HARQ information fed back to the target PDSCH. It can be understood that ACK is transmitted if decoding is successful and NACK is transmitted if decoding is unsuccessful according to the target PDSCH position indicated by PDCCH.

Step 230, sending the uplink information at a preset uplink information sending time, and starting a first timer.

And step 240, in response to the preset downlink information receiving time overlapping with the inactive sending time, starting or restarting a second timer after the inactive sending time is over, and receiving the downlink information.

Step 240 is performed under the condition that the target PDSCH decoding fails.

The first timer is a pre-timer of the second timer, that is, the preset second timer operation period occurs after the first timer times out. The second timer is started after the first timer expires (or when the timing duration is reached), e.g., the second timer is started in the first symbol after the expiration of the first timer.

The preset downlink information receiving time is within a preset second timer working period.

For example, if the preset working start time of the second timer falls within the inactive sending time, the second timer is started after the inactive sending time is ended, and the downlink information is received.

For another example, if the preset second timer start time does not fall within the inactive transmission time, the second timer is started in response to the timeout of the first timer; and receiving downlink information in the second timer working area.

Further, in one embodiment of the present application, the second timer is ended in response to successful reception of the downlink information. In contrast, if the second timer does not end after the downlink information is successfully received and overlaps the inactive transmission time within the timing duration of the second timer, the second timer does not need to be restarted after the inactive transmission time ends.

Preferably, in one embodiment of the present application, the downlink information is not received within a time range in which a preset downlink information receiving time overlaps with an inactive transmission time.

For example, when the terminal receives the downlink information and overlaps with the inactive time period of the discontinuous transmission of the base station, the terminal does not receive the downlink information, and the terminal restarts the second timer at the first symbol after the end of the inactive time of the discontinuous transmission of the base station.

Further for example, the downlink information is downlink PDCCH control information, if the duration Retransmission Timer DL overlaps with the inactivity time of the discontinuous transmission by the base station, the UE does not monitor the retransmission of PDCCH during the overlapping period similar to the new transmission case, and starts or restarts Retransmission Timer DL in the first symbol after the inactivity time of the discontinuous transmission by the base station ends. Thus ensuring that the terminal can receive retransmissions immediately after the end of the inactivity period of the cell discontinuous transmission.

For further example, the downlink information is downlink PDCCH control information, if the Retransmission Timer DL th duration partially overlaps with the non-active time of the discontinuous transmission of the base station, the terminal receives the downlink PDCCH control information for retransmission in a non-overlapping period, if the base station is at the non-active time of the discontinuous transmission after successful reception, the terminal stops Retransmission Timer DL, if the base station is at the non-active time of the discontinuous transmission after unsuccessful reception, the terminal stops Retransmission Timer DL, and restarts Retransmission Timer DL in the first symbol after the end of the non-active period of the discontinuous transmission of the base station.

Based on the embodiments of fig. 3 to 4, it should be noted that when both an uplink information conflict and a downlink information conflict exist, the foregoing embodiments may also be combined, for example, the method of the embodiment of the present application may further include step 130 and step 140, for example, in one embodiment of the present application, steps 110 to 130 and 240 are included.

It should also be noted that, the above embodiment is used for a network entity of a wireless communication system, where the network entity includes a terminal side device; the above steps may also be used for a service device providing information processing for the network entity; the above steps may also be applied to any apparatus, system, subsystem, circuit, chip or software running entity that provides information receiving, transmitting, identifying, and processing for the terminal side device.

The downlink signaling, for example, the signaling that the first downlink signaling is a semi-static indication, indicates a base station inactive reception start time and an inactive transmission start time, and a period of base station inactive reception and a period of inactive transmission.

The downlink signaling, for example, the second downlink signaling and the third downlink signaling are dynamically indicated signaling. The second downlink signaling indicates the duration of inactive receiving of the base station, and the third downlink signaling indicates the duration of inactive sending of the base station.
