Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a processing method and a terminal for discontinuous reception.
Background
The Discontinuous Reception (DRX) mechanism may allow a terminal in a Radio Resource Control (RRC) Connected state (Connected) to monitor a Physical Downlink Control Channel (PDCCH) subframe only at certain times of a DRX cycle (cycle), thereby achieving balance between scheduling flexibility and power saving. As shown in fig. 1, the DRX cycles are divided into consecutive DRX cycles in the time domain, and each DRX cycle includes an On Duration (On Duration) and a sleep Duration (Opportunity for DRX). The terminal monitors the PDCCH for a long duration, and does not monitor the PDCCH during a sleep period to save power.
When the channel quality of some cells is not good or the channel blocking rate is high, the network device may configure cross-carrier scheduling for the terminal. The cross-carrier scheduling is to configure a control channel in a cell with better channel quality (i.e. a scheduling cell, such as a primary cell), and schedule data of other cells (i.e. scheduled cells, such as a secondary cell) in a cross-carrier manner. The scheduling cell may schedule its own cell and one or more other scheduled cells than itself. The scheduled cell has no PDCCH and can only be scheduled by the scheduling cell. When the network device configures cross-carrier scheduling, if the network device configures a plurality of independent DRX configurations for the terminal, and an MAC entity of the terminal performs uplink/downlink transmission, the terminal cannot determine how to perform processing of the plurality of independent DRX configurations, and thus cannot determine parameters of a timer related to DRX.

Referring to fig. 2, fig. 2 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 21 and a network device 22. The terminal 21 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 21 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 21 is not limited in the embodiment of the present invention. The network device 22 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.
The base stations may communicate with the terminals 21 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.
The base stations may communicate wirelessly with the terminals 21 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.
The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 21 to network device 22) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 22 to terminal 21). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.
An embodiment of the present invention provides a processing method for discontinuous reception, as shown in fig. 3, the method includes the following steps:
step 31: under the condition that the terminal is configured with cross-carrier scheduling, after a Physical Downlink Control Channel (PDCCH) is monitored in the Active Time (Active Time) of a Discontinuous Reception (DRX) cycle, a DRX timer in a target DRX configuration is started.
Wherein, the activation time of the DRX period includes but is not limited to: duration, and/or a DRX duration timer (DRX-onDurationTimer), a DRX deactivation timer (DRX-inactivity timer), a downlink discontinuous reception retransmission timer (DRX-retransmission timer), an uplink discontinuous reception retransmission timer (DRX-retransmission timer ul), a contention resolution timer (ra-ContentionResolutionTimer), etc. The PDCCH is used for scheduling or authorizing data transmission of the terminal in the scheduled cell, and the target DRX configuration may be associated with the scheduling cell, where the scheduling cell is a cell that sends the PDCCH, that is, a cell where the PDCCH monitored by the terminal is located, that is, the target DRX configuration is associated with the cell where the PDCCH is monitored. The target DRX configurations may be in one-to-one correspondence with the scheduling cells, that is, the network device configures respective DRX configurations for each scheduling cell, and the DRX configurations corresponding to different scheduling cells may be the same or different. The corresponding relationship between the target DRX configuration and the scheduling cell may be one-to-many, that is, the network device configures the same DRX configuration for multiple scheduling cells, for example, the network device configures one DRX configuration for the licensed band and configures another DRX configuration for the unlicensed band, so that all scheduling cells in the licensed band correspond to the same DRX configuration, and all scheduling cells in the unlicensed band correspond to the same DRX configuration. The correspondence of the target DRX configuration to the scheduling cell may also be many-to-one, i.e. the network device configures multiple DRX configurations for one scheduling cell, for example, the target DRX configuration may be associated with a Bandwidth Part (BWP) of the scheduling cell, and when multiple BWPs are included in the scheduling cell, one BWP corresponds to one DRX configuration, where the DRX configurations corresponding to different BWPs may be the same or different.
Alternatively, the target DRX configuration may be associated with a scheduled cell, which is a cell that receives downlink data or transmits uplink data. The PDCCH may be used for scheduling downlink data transmission and may also be used for performing uplink grant data transmission. Accordingly, the target DRX configuration may be associated with a cell in which downlink data, such as a Physical Downlink Shared Channel (PDSCH), is received, or associated with a cell in which Uplink data, such as a Physical Uplink Shared Channel (PUSCH), is transmitted. The target DRX configurations may be in one-to-one correspondence with the scheduled cells, that is, the network device configures respective DRX configurations for each scheduled cell, and the DRX configurations corresponding to different scheduled cells may be the same or different. The corresponding relationship between the target DRX configuration and the scheduled cell may be one-to-many, that is, the network device configures the same DRX configuration for multiple scheduled cells, for example, the network device configures one DRX configuration for the licensed band and configures another DRX configuration for the unlicensed band, then the scheduled cells in all licensed bands correspond to the same DRX configuration, and the scheduled cells in all unlicensed bands correspond to the same DRX configuration. The correspondence of the target DRX configuration to the scheduled cell may also be many-to-one, i.e. the network device configures multiple DRX configurations for one scheduled cell, for example, the target DRX configuration may be associated with BWP of the scheduled cell, and when multiple BWPs are included in the scheduled cell, one BWP corresponds to one DRX configuration, where the DRX configurations corresponding to different BWPs may be the same or different.
In the embodiment of the invention, when network equipment configures cross-carrier scheduling for a terminal, the terminal monitors a Physical Downlink Control Channel (PDCCH) within the activation time of a DRX period during uplink and downlink data transmission, and then starts a DRX timer in target DRX configuration. The target DRX configuration may be associated with a scheduling cell or a scheduled cell, and thus, in cross-carrier scheduling, the terminal may select a DRX timer in the target DRX configuration among a plurality of DRX with independent configurations when performing uplink and downlink data transmission. Therefore, when the cross-carrier scheduling is carried out, the terminal can determine which DRX configuration timer should be started in the uplink and downlink transmission, and the DRX transmission is ensured to be normally carried out. The following embodiments of the present invention will further explain the uplink and downlink transmission in combination with different scenarios.
1. Taking PDCCH for scheduling downlink data transmission as an example.
Wherein, the HARQ process corresponds to downlink data, and during the data transmission process, there may be multiple HARQ processes simultaneously performed on one carrier (cell), where the HARQ process refers to one or more processes related to downlink data transmission. The parameter value of the first timer is determined from the target DRX configuration, and the PDCCH is not monitored during the timing period of the first timer. Alternatively, the first timer may be a downlink discontinuous reception hybrid automatic repeat request Round Trip Time (RTT) timer (drx-HARQ-RTT-TimerDL).
Assume that a current network device configures cross-Carrier scheduling for a terminal, wherein a PDCCH is transmitted on BWP 1 with BWP Identification (ID) of 1 on serving cell 1 (i.e., scheduling cell) on Component Carrier 1 (CC 1) in a licensed band, the PDCCH can schedule serving cell 2 (i.e., scheduled cell) on Component Carrier CC 2 in an unlicensed band, and the terminal receives a PDSCH on BWP 2 with BWP ID of 2 on serving cell 2. Wherein serving cell 1 and DRX configuration 1 are associated, and serving cell 2 and DRX configuration 2 are associated. Alternatively, BWP 1 and DRX configuration 1 of serving cell 1 are associated and BWP 2 and DRX configuration 2 of serving cell 2 are associated.
If the terminal monitors a PDCCH indicating downlink data transmission, the terminal feeds back response information of the downlink data to the network device after receiving corresponding downlink data (e.g., PDSCH). The terminal starts a first timer (e.g., DRX-HARQ-RTT-TimerDL) associated with the HARQ process in DRX configuration 1 corresponding to the scheduling cell (i.e., the serving cell that monitors the PDCCH) at a first OFDM symbol (e.g., a start time) after sending the response information of the downlink data. Or, the terminal starts a first timer (e.g., DRX-HARQ-RTT-TimerDL) associated with the HARQ process in DRX configuration 2 corresponding to the scheduled cell (i.e., the serving cell receiving the PDSCH) at the start time of the first OFDM symbol after the response information of the downlink data is transmitted.
The response information of the downlink data may be sent through a Physical Uplink Control Channel (PUCCH), that is, a first timer is started at a starting time of a first OFDM symbol after the PUCCH corresponding to the downlink data is sent, where the first timer is DRX-HARQ-RTT-TimerDL associated with an HARQ process in a DRX configuration associated with a serving cell (or BWP) where the terminal monitors the PDCCH or receives the PDSCH. Wherein the parameters of the first timer comprise a duration parameter for determining a DRX-HARQ-RTT-TimerDL timer from the DRX configuration.
Further, after the step of starting the first timer related to the hybrid automatic repeat request HARQ process in the target DRX configuration, the method further comprises: and starting a second timer related to the HARQ process in the target DRX configuration under the condition that the first timer is overtime and the downlink data is not successfully decoded. And the parameter value of the second timer is determined from the target DRX configuration, and the PDCCH is monitored or downlink data is received during the timing period of the second timer. Alternatively, the second timer may be a downlink discontinuous reception retransmission timer (drx-retransmission timerdl).
When a DRX-HARQ-RTT-TimerDL timer corresponding to a HARQ process is expired and data transmitted in the HARQ process is not decoded successfully, e.g., when the HARQ process fails, the terminal starts a second timer (e.g., DRX-retransmission TimerDL) associated with the HARQ process in the target DRX configuration. It is worth noting that the first timer needs to be stopped when the second timer is started.
Further, when the starting condition of the second timer is satisfied, that is, when the first timer is out of time and the downlink data is not successfully decoded, the starting time of the second timer may be: and the first OFDM symbol after the first timer is overtime. That is, when the first timer expires and the downlink data is not successfully decoded, the second timer is started at the first OFDM symbol (e.g., the start time) after the first timer expires. The parameters of the first timer and the second timer may be obtained from the same DRX configuration, or may be obtained from different DRX configurations.
For example: the terminal monitors a PDCCH indicating downlink data transmission. Then, after receiving the corresponding downlink data (e.g. PDSCH), the terminal feeds back response information of the downlink data to the network device. And the terminal starts DRX-HARQ-RTT-TimerDL associated with the HARQ process in DRX configuration 1 corresponding to the scheduling cell at the starting time of the first OFDM symbol after the response information of the downlink data is sent. And under the condition that the DRX-HARQ-RTT-TimerDL is overtime and the related downlink data of the HARQ process is not successfully decoded, starting DRX-retransmission TimerDL in DRX configuration 1 or DRX configuration 2 at the starting moment of the first OFDM symbol after the DRX-HARQ-RTT-TimerDL is overtime. Or the terminal starts DRX-HARQ-RTT-TimerDL associated with the HARQ process in DRX configuration 2 corresponding to the scheduled cell at the start time of the first OFDM symbol after the response information of the downlink data is sent. And under the condition that the DRX-HARQ-RTT-TimerDL is overtime and the related downlink data of the HARQ process is not successfully decoded, starting DRX-retransmission TimerDL in DRX configuration 1 or DRX configuration 2 at the starting moment of the first OFDM symbol after the DRX-HARQ-RTT-TimerDL is overtime.
That is, in case that DRX-HARQ-RTT-TimerDL is expired and downlink data associated with a HARQ process is not successfully decoded, the terminal starts a DRX-retransmission TimerDL timer associated with the HARQ process in a DRX configuration associated with a scheduling cell (i.e., a serving cell that monitors a PDCCH) or a scheduled cell (i.e., a serving cell that receives a PDSCH) at a start time of a first OFDM symbol after the DRX-HARQ-RTT-TimerDL timer is expired, and determines a parameter value of the DRX-retransmission TimerDL timer from the DRX configuration.
Further, after the step of starting the second timer, the method further comprises: and if the PDCCH is monitored or downlink data is received, stopping the second timer. Taking drx-retransmission timerdl as an example, the terminal monitors the PDCCH or PDSCH during drx-retransmission timerdl timing, and stops drx-retransmission timerdl when drx-retransmission timerdl times out, monitors the PDCCH, or receives the PDSCH.
2. Take PDCCH for authorizing transmission of uplink data as an example.
Wherein, the HARQ process corresponds to uplink data, and during the data transmission process, there may be multiple HARQ processes simultaneously performed on one carrier (cell), where the HARQ process refers to one or more processes related to uplink data transmission. And the parameter value of the third timer is determined from the target DRX configuration, and the PDCCH is not monitored during the timing period of the third timer. Optionally, the third timer is an uplink discontinuous reception hybrid automatic repeat request round trip time timer (drx-HARQ-RTT-timerll).
Assume that a current network device configures cross-Carrier scheduling for a terminal, wherein a PDCCH is transmitted on BWP 1 with BWP Identification (ID) of 1 on serving cell 1 (i.e., scheduling cell) on Component Carrier 1 (CC 1) in a licensed band, the PDCCH can schedule serving cell 2 (i.e., scheduled cell) on Component Carrier CC 2 in an unlicensed band, and the terminal transmits a PUSCH on BWP 2 with BWP ID of 2 on serving cell 2. Wherein serving cell 1 and DRX configuration 1 are associated, and serving cell 2 and DRX configuration 2 are associated. Alternatively, BWP 1 and DRX configuration 1 of serving cell 1 are associated and BWP 2 and DRX configuration 2 of serving cell 2 are associated.
If the terminal monitors a PDCCH indicating uplink transmission, the terminal starts a third timer (e.g., DRX-HARQ-RTT-timerll) associated with the HARQ process in DRX configuration 1 corresponding to the scheduling cell (i.e., the serving cell monitoring the PDCCH) at the start time of the first OFDM symbol after transmitting the uplink data. Or, the terminal starts a third timer (e.g., DRX-HARQ-RTT-timerll) associated with the HARQ process in DRX configuration 2 corresponding to the scheduled cell (i.e., the serving cell transmitting the PUSCH) at the start time of the first OFDM symbol after the uplink data is transmitted.
After monitoring a PDCCH indicating uplink transmission, the terminal starts, at the start time of the first OFDM symbol after the PUSCH corresponding to the PDCCH is first transmitted, to monitor DRX-HARQ-RTT-timerll associated with the HARQ process in a DRX configuration associated with a serving cell (or BWP) where the PDCCH or the PUSCH is transmitted, and may determine a duration parameter of a DRX-HARQ-RTT-timerll timer from the DRX configuration.
Further, the step of starting a third timer related to the HARQ process in the target DRX configuration further includes: and starting a fourth timer related to the HARQ process in the target DRX configuration under the condition that the third timer is overtime. And determining a parameter value of a fourth timer from the target DRX configuration, and monitoring the PDCCH during the timing period of the fourth timer. Optionally, the fourth timer may be an uplink discontinuous reception retransmission timer (drx-retransmission timer ul).
When the DRX-retransmission timerll timer corresponding to a HARQ process is over, the terminal starts a fourth timer (e.g., DRX-retransmission timerll) associated with the HARQ process in the target DRX configuration. It is worth noting that the third timer needs to be stopped when the fourth timer is started.
Further, when the starting condition of the fourth timer is satisfied, that is, in the case that the third timer times out, the starting time of the fourth timer may be: and the first OFDM symbol after the third timer is overtime. That is, the step of starting the fourth timer related to the HARQ process in the target DRX configuration includes: the fourth timer is started at the first OFDM symbol (e.g., the start time) after the third timer expires. The parameters of the third timer and the fourth timer may be obtained from the same DRX configuration, or may be obtained from different DRX configurations.
For example: the terminal monitors a PDCCH indicating uplink scheduled data transmission, and then starts DRX-HARQ-RTT-timerll associated with the HARQ process in DRX configuration 1 corresponding to the scheduling cell at the start time of the first OFDM symbol after transmitting corresponding uplink data. And under the condition that the DRX-HARQ-RTT-TimerUL is overtime, starting the DRX-retransmission TimerUL in the DRX configuration 1 or the DRX configuration 2 at the starting time of the first OFDM symbol after the DRX-HARQ-RTT-TimerUL is overtime. Or the terminal starts DRX-HARQ-RTT-timerll associated with the HARQ process in DRX configuration 2 corresponding to the scheduled cell at the start time of the first OFDM symbol after the uplink data is transmitted. And under the condition that the DRX-HARQ-RTT-TimerUL is overtime, starting the DRX-retransmission TimerUL in the DRX configuration 1 or the DRX configuration 2 at the starting time of the first OFDM symbol after the DRX-HARQ-RTT-TimerUL is overtime.
That is, the terminal starts a DRX-retransmission timerll timer associated with the HARQ process in a DRX configuration associated with a scheduling cell (i.e., a serving cell that monitors a PDCCH) or a scheduled cell (i.e., a serving cell that receives a PDSCH) at a start time of a first OFDM symbol after the DRX-HARQ-RTT-timerll timer expires, and may determine a parameter value of the DRX-retransmission timerll timer from the DRX configuration.
Further, the step of starting a fourth timer related to the HARQ process in the target DRX configuration further includes: and if the PDCCH is monitored, stopping the fourth timer. Taking drx-retransmission timerll as an example, the terminal keeps monitoring the PDCCH during drx-retransmission timerll timing, and stops drx-retransmission timerll when drx-retransmission timerll times out or monitors the PDCCH.
That is to say, when performing uplink/downlink data transmission, the terminal according to the embodiment of the present invention starts a DRX Timer associated with an HARQ process in a DRX configuration associated with a serving cell (scheduling cell) that monitors a PDCCH or a serving cell (scheduled cell) that receives a PDSCH or transmits a PUSCH, and determines a duration parameter of the DRX Timer corresponding to the HARQ process from the DRX configuration.
When the DRX-HARQ-RTT-Timer corresponding to a certain HARQ process is expired, starting a DRX-retransmission Timer associated with the HARQ process in a DRX configuration associated with a serving cell (scheduling cell) that monitors a PDCCH or a serving cell (scheduled cell) that receives a PDSCH or transmits a PUSCH, and determining a duration parameter of the DRX-retransmission Timer corresponding to the HARQ process from the DRX configuration.
In the discontinuous reception processing method of the embodiment of the invention, when the terminal is scheduled in a cross-carrier mode, the terminal can determine which DRX configuration timer should be started in uplink and downlink transmission, thereby ensuring that a plurality of independent DRX configurations are correctly processed and the DRX transmission is normally carried out.
The foregoing embodiments describe processing methods for discontinuous reception in different scenarios, and further describe terminals corresponding to the foregoing embodiments with reference to the accompanying drawings.

The terminal 400 specifically includes the following functional modules:

Wherein, the starting module 410 further comprises:
