Technical Field

Background
With the continuous development of the fifth generation (5th generation,5G) communication system, the frequency spectrum used is wider, the number of configured transmitting antennas is larger, and the overall power consumption of access network equipment is higher.
It is noted that the power consumption at the network side is not proportional to the traffic load, and that the power consumption of the access network device per transmission time interval (transmission time interval, TTI) comprises a number of parts, e.g. a dynamic power consumption part related to the load, a static power consumption part independent of the load. That is, even when the load is light, the static part independent of the load still causes the access network device to consume energy.
In the existing NR protocol, a discontinuous reception (dis-continuous reception, DRX) mechanism is supported to be configured for the terminal equipment, so that the terminal equipment can only detect a downlink control channel (physical downlink control channel, PDCCH) in a specified time period, but the technology only acts on part of transmission channels and signals, the access network equipment cannot realize the turn-off of data transmission through the DRX configuration of the UE, and the dormancy of the access network side cannot be completely realized.
In the current communication process, the access network equipment cannot realize complete turn-off of data transmission through the existing DRX configuration mechanism of the UE, so that the power consumption of the access network equipment side is higher, and unnecessary energy loss is caused.

The terminal is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or may integrate the functions of the core network device and the logic functions of the radio access network device on the same physical device, or may integrate the functions of part of the core network device and part of the radio access network device on one physical device. The terminals and the radio access network device may be connected to each other by wired or wireless means. Fig. 1 is only a schematic diagram, and other network devices may be further included in the communication system, for example, a wireless relay device and a wireless backhaul device may also be included, which are not shown in fig. 1.
The access network device may also be referred to as AN access device, where the (R) AN may be capable of managing radio resources, providing access services for the user device, and completing forwarding of user device data between the user device and the core network, and may also be understood as a base station in the network.
The access network device in the embodiments of the present application may be any communication device with a wireless transceiver function for communicating with a user device. The access network device includes, but is not limited to: base station (base station), evolved NodeB (eNodeB), transmission and reception point (transmission reception point, TRP), next generation NodeB (gNB) in the fifth generation (5th generation,5G) mobile communication system, next generation base station in the sixth generation (6th generation,6G) mobile communication system, base station in the future mobile communication system, access node in the WiFi system, or the like; the present invention may also be a module or unit that performs a function of a base station part, for example, a Central Unit (CU) or a Distributed Unit (DU). The CU can complete the functions of a radio resource control protocol and a packet data convergence layer protocol (packet data convergence protocol, PDCP) of the base station and can also complete the functions of a service data adaptation protocol (service data adaptation protocol, SDAP); the DU performs the functions of the radio link control layer and the medium access control (medium access control, MAC) layer of the base station, and may also perform the functions of a part of the physical layer or the entire physical layer, and for a detailed description of the above protocol layers, reference may be made to the relevant technical specifications of the third generation partnership project (3rd generation partnership project,3GPP).

It is understood that the access network device may be a device comprising one or more of a CU node, a DU node, an AAU node.

The application scenes of the base station and the terminal are not limited in the embodiment of the application.
The roles of base station and terminal may be relative, e.g., helicopter or drone 120i in fig. 1 may be configured as a mobile base station, terminal 120i being the base station for those terminals 120j that access radio access network 100 through 120 i; but for base station 110a 120i is a terminal, i.e., communication between 110a and 120i is via a wireless air interface protocol. Of course, communication between 110a and 120i may be performed via an interface protocol between base stations, and in this case, 120i is also a base station with respect to 110 a. Thus, both the base station and the terminal may be collectively referred to as a communication device, 110a and 110b in fig. 1 may be referred to as a communication device having base station functionality, and 120a-120j in fig. 1 may be referred to as a communication device having terminal functionality.

In an actual deployment, the network elements in the core network may be deployed on the same or different physical devices. For example, as one possible deployment, the AMF and SMF may be deployed on the same physical device. For another example, the network element of the 5G core network may be deployed on the same physical device as the network element of the 4G core network. The embodiments of the present application are not limited in this regard.
It should be understood that fig. 1 is only an example, and the scope of protection of the present application is not limited in any way. The communication method provided in the embodiment of the present application may also relate to a network element not shown in fig. 1, and of course, the communication method provided in the embodiment of the present application may also include only a part of the network elements shown in fig. 1.
With the continuous development of the fifth generation (5th generation,5G) communication system, the frequency spectrum used is wider, the number of configured transmitting antennas is larger, and the overall power consumption of access network equipment is higher. The power consumption at the network side is not proportional to the traffic load, but the power consumption of the access network device at each transmission time interval (transmission time interval, TTI) comprises a number of parts, such as a dynamic power consumption part related to the load, a static power consumption part independent of the load. That is, even when the load is light, the static part independent of the load still causes the access network device to consume energy.
In the existing NR protocol, a discontinuous reception (dis-continuous reception, DRX) mechanism is supported to be configured for the terminal equipment, so that the terminal equipment can only detect a downlink control channel (physical downlink control channel, PDCCH) in a specified time period, but the technology only acts on part of transmission channels and signals, the access network equipment cannot realize the turn-off of data transmission through the DRX configuration of the UE, and the dormancy of the access network side cannot be completely realized.
How to realize dynamic turn-off according to service load and reduce power consumption of access network equipment has become a key problem in current research.
To facilitate an understanding of the embodiments of the present application, the terms referred to in this application are briefly described.
1. Synchronization signal/physical broadcast signal (synchronization signals/PBCH, SSB): including primary synchronization signals (primary synchronization signals, PSS), secondary synchronization signals (secondary synchronization signals, SSS), physical broadcast channels (physical broadcast channel, PBCH). The PSS/SSS is mainly used for downlink synchronization of terminal equipment and obtaining of cell Identification (ID), wherein the downlink synchronization comprises clock synchronization, wireless frame synchronization and symbol synchronization. The PBCH is mainly used for carrying a main information block (master information block, MIB), and the MIB includes information such as a system frame number (system frame number, SFN), a subcarrier interval, PDCCH configuration of scheduling system information (system information, SI), and the like.
2. Physical random access channel (physical random access channel, PRACH): in the random access process of the terminal equipment, the network equipment needs to configure PRACH for the terminal equipment for accessing the system. Since the movement of the terminal device makes the distance between the terminal device and the network device uncertain, if the terminal device needs to send a message to the base station, maintenance management of uplink synchronization must be performed in real time. The purpose of the PRACH is to achieve uplink synchronization, establish a relationship between the terminal equipment and the network equipment uplink synchronization, and request the network equipment to allocate dedicated resources to the terminal equipment, so that the terminal equipment normally accesses the network equipment to perform service transmission.
3. Radio Network Temporary Identifier (RNTI) of information-radio network temporary identifier: the RNTI is used to distinguish or identify a terminal device connected in a cell, a group of terminal devices in a specific radio channel or paging situation, a group of terminal devices receiving power control parameters, or system information transmitted by a network device for all terminal devices. The RNTI may be a 16-bit identifier whose value depends on the type of RNTI. Among them, the RNTI for paging (paging) is denoted as P-RNTI. In addition to this are a cell radio network temporary identity (cell radio network temporary identifier, C-RNTI) for data scheduling, a modulation and coding scheme cell radio network temporary identity (modulation and coding scheme cell radio network temporary identifier, MCS-C-RNTI), a configuration scheduling radio network temporary identity (configured scheduling radio network temporary identifier, CS-RNTI), etc.
4. Physical downlink control channel (physical downlink control channel, PDCCH): the UE determines, through the base station configuration in a search space (search space) and a control resource set CORESET (control resource set), a time domain and a frequency domain position occupied by the base station to possibly transmit the PDCCH.
5. Physical downlink shared channel (physical downlink shared channel, PDSCH): scheduling of NR downlink data is divided into two categories: one is PDSCH based on PDCCH dynamic scheduling, and the other is PDSCH of semi-static scheduling;
dynamic scheduling is to transmit one PDCCH to schedule one PDSCH, and one PDCCH needs to be transmitted before each PDSCH is transmitted. The PDCCH includes information such as a time domain position and a frequency domain position of the scheduled PDSCH, and the terminal device receives the PDSCH according to the information.
The semi-static scheduling is that the network equipment sends a PDCCH, the PDCCH activates the semi-static scheduling configuration of the RRC signaling configuration, the semi-static configuration comprises a period for the PDSCH to issue, and the terminal equipment periodically receives the PDSCH according to the period, wherein the time domain and frequency domain positions of the PDSCH in different slots are determined according to the time domain and frequency domain resource allocation in the activated PDCCH.
6. Physical uplink shared channel (physical downlink shared channel, PUSCH): the current PUSCH transmissions can also be divided into three categories:
A. Dynamic grant, grant bared, essentially PUSCH transmission based on PDCCH dynamic scheduling (scheduling mechanism is similar to PDSCH reception based on PDCCH dynamic scheduling).
B. configured grant type 1 the base station transmits configuration to the UE through RRC signaling configuration GrantConfig, the signaling contains RRC-ConfiguredUplinkGrant, UE, if there is a requirement for PUSCH transmission, the PUSCH can be directly transmitted according to the configuration, and the base station does not need to wait for DCI scheduling or activation to be transmitted; this approach is also called PUSCH of grant free
C. configured grant type 2 the base station first issues RRC layer signaling configurable grant (excluding RRC-configurable uplink grant) and then the UE needs to receive DCI issued by the base station to activate the configuration. After the UE is activated, periodic data transmission is performed at a fixed time of the fixed resource. This approach is also called semi-static PUSCH (similar to semi-static PDSCH).
7. Signal reference signal (sounding reference signal, SRS) and channel state information (channel state information): the SRS is a signal transmitted by the UE to the base station for measuring channel quality; the CSI is the CSI-RS sent by the base station, and the UE receives the report information after measurement; SRS and CSI reporting are uplink signals sent by UE and are divided into three types of Aperiodic/periodic/Semi-static (A/P/SP) signals:
a-SRS/A-CSI, based on the uplink signal transmission triggered by the PDCCH issued by the base station, triggering one transmission (similar to dynamic PDSCH/PUSCH scheduling);
the P-SRS/P-CSI is periodically transmitted, namely the base station configures RRC signaling configuration for SRS/CSI reporting, and the UE transmits the SRS/CSI reporting according to the configuration period;
the SP-SRS/SP-CSI is also periodically transmitted, but the UE can periodically transmit according to the configuration, wherein the base station is required to configure RRC configuration and the base station is required to issue PDCCH trigger; (similar to configrued grant type/SPS PDSCH).
8. Channel state information reference signal (channel state information reference signal, CSI-RS): the CSI-RS is a downlink reference signal sent by the base station, and is received and measured by the UE (the measurement is sent to the base station in the CSI report); the CSI-RS measurement behavior of the UE is also divided into three types of A/P/SP:
a-CSI-RS, based on the base station issuing PDCCH telling the UE where to measure, triggers one measurement once (similar to dynamic PDSCH/PUSCH scheduling);
the P-CSI-RS is periodically measured, namely, the base station is configured with CSI-RS measurement configuration, and the UE measures channels according to the configuration period;
SP-CSI is also periodic measurement, but the UE can periodically measure according to the configuration, wherein the base station is required to configure CSI-RS measurement configuration and the base station is required to issue PDCCH trigger; (similar to configrued grant type/SPS PDSCH).
9. Discontinuous transmission (dis-continuous transmission, DTX) mechanism-to further reduce power consumption by a communication device, the communication device may be enabled to not transmit data transmissions for a period of time, or the communication device may be enabled to not transmit all or part of the channels for a period of time. This way of reducing the power consumption of the communication device may be referred to as a DTX mechanism.
DTX has different interpretations for two or more communication devices communicating due to the interactivity of the communication system. DTX may be understood as a discontinuous transmission scheme for a transmitting device and a discontinuous reception scheme for a receiving device corresponding to a transmitting device configured with DTX at this time. For convenience of description, DTX in this application refers to a cell-level discontinuous transmission mechanism, and for convenience of description, DTX in the cell level may also be understood as a network device DTX mechanism, through which energy saving of a network device may be achieved, since the network device may communicate with a plurality of terminal devices in a cell.
For example, the network device may set a transmission pattern, and perform data transmission only for a part of a period of time in a transmission period, and perform no data transmission and reception for other periods of time.
When there is no traffic load, a network device DTX mechanism may be employed, thereby reducing the power consumption of the network device.
When the traffic load is light, although there is data transmission on many transmission time intervals, the resource utilization rate of the transmission time intervals is low, at this time, a network device DTX mechanism may also be adopted, and the data to be transmitted is collected to the time period a for transmission, so that the data may enter the DTX state in the time period B, and static energy saving of the network device is achieved.
10. Non-continuous reception (dis-continuous reception, DRX) mechanism, which enables the terminal to perform downlink control channel (physical downlink control channel, PDCCH) detection only for a prescribed period of time, but the technique works only on part of the transmission channel, the signal, and the base station cannot completely realize silence of the base station through the DRX configuration of the UE.
The basic mechanism of DRX is to configure a DRX cycle for a terminal device in radio resource control (radio resource control, RRC) connected state. The DRX cycle consists of "Duration" (on Duration) and "opportunity for DRX" (Opportunity for DRX): during the "duration" period, the terminal device detects and receives a physical downlink control channel (physical downlink control channel, PDCCH); and in the period of the "opportunity of DRX", the terminal device does not detect the PDCCH to save power consumption.
Herein, the period of "duration" is also referred to as an activation period, and the period of "opportunity of DRX" is also referred to as a deactivation period. Fig. 2 is a schematic diagram of an exemplary DRX basic model provided in the present application. As shown in fig. 2, the terminal device in the RRC connected state periodically enters an activation period and a deactivation period, and when the terminal device enters the activation period, the terminal device detects the PDCCH, and when the terminal device enters the deactivation period, the terminal device does not detect the PDCCH any more, that is, the terminal device is not required to be in a state of detecting the PDCCH all the time, thereby achieving the purpose of reducing power consumption of the terminal.
Currently, the base station transmits DRX configuration information to the terminal device, so that the terminal device enters an active mode in a specified period of time based on the DRX configuration information, and enters a deactivated mode in the rest of time, so as to realize dormancy under the DRX mechanism. Specifically, the following parameters are mainly included in the DRX configuration:
activation time timer (on Duration Timer): it may be understood that a continuous number of downlink subframes indicates the time that the terminal device can maintain after waking up from a sleep state. Within the continuous downlink subframe number, the terminal device needs to monitor the physical downlink control channel.
DRX Inactivity Timer (DRX-Inactivity Timer): also understood as a continuous number of downlink subframes. The DRX inactivity timer is started when the terminal device successfully demodulates the first symbol after receiving the PDCCH which belongs to scheduling a new transmission (uplink or downlink) of the terminal device, and indicates a duration of the corresponding MAC to monitor the PDCCH after receiving a PDCCH indicating the new transmission. That is, it is also necessary to continue listening to the physical downlink control channel during the timing period of the DRX inactivity timer.
A downlink hybrid automatic repeat request (hybrid automatic repeat request, HARQ) Round Trip Time (RTT) Timer (Timer) and a downlink DRX retransmission Timer (DRX-Retransmission Timer): when the terminal device receives 1 downlink control information (downlink control information, DCI) indicating that a physical downlink shared control channel (physical downlink shared channel, PDSCH) transmission or a downlink semi-persistent scheduling (semi-persistent scheduling, SPS) PDSCH transmission is received (without distinguishing whether PDSCH is a new transmission or a retransmission), the terminal device starts downlink HARQ-RTT-Timer and stops downlink DRX retransmission Timer at the first symbol start time after the end symbol of the physical uplink control channel (physical uplink control channel, PUCCH) carrying feedback information "ACK/NACK" of the PDSCH transmission; when the downlink HARQ-RTT-Timer ends and the terminal device does not successfully receive the PDSCH transmission, a downlink DRX retransmission Timer is started, and if the terminal device successfully receives the PDSCH transmission, downlink Retransmission Timer is not started.
Uplink hybrid automatic repeat request (hybrid automatic repeat request, HARQ) Round Trip Time (RTT) Timer (Timer) and uplink DRX retransmission Timer (DRX-Retransmission Timer): when the terminal device receives 1 DCI indicating that a physical uplink shared control channel (physical uplink shared channel, PUSCH) transmission or a PUSCH transmission of an uplink grant (CG) type is activated, the terminal device starts an uplink HARQ-RTT-Timer and stops an uplink DRX retransmission Timer at a first symbol start time after an end symbol of a first repetition of the PUSCH transmission; and starting the uplink Retransmission Timer when the uplink HARQ-RTT-Timer is ended.
In summary, the terminal device is considered to be in an Active Time period (Active Time) in any of the following cases, otherwise, in a deactivated Time period (Inactive Time): an active time timer, a DRX inactive timer, a downlink DRX retransmission timer, and an uplink DRX retransmission timer.
In addition, under the DRX mechanism, when the terminal device sends a scheduling request and the scheduling request is in a suspension "pending" state, and when the terminal device receives the PDCCH after the end of the non-contention based random access procedure, the terminal device indicates that a new transmission of a cell radio network temporary identity scrambling has not been successfully received, the terminal device is also considered to be in an active period.
That is, with the DRX mechanism, during the operation of the active time timer, the DRX inactivity timer, the downlink DRX retransmission timer, the uplink DRX retransmission timer, and when the terminal device transmits a scheduling request and the scheduling request is in a suspended "pending" state and the terminal device receives a PDCCH indicating that a new transmission of one cell radio network temporary identity scrambling has not been successfully received, the terminal device is in a period in which detection of the PDCCH is performed, and in the remaining periods, the terminal device is in a deactivated period in which no PDCCH detection is performed, so as to reduce power consumption of the terminal device.
The deactivation period may also be referred to herein as a sleep period under the DRX mechanism.
The technology only works on partial transmission channels and signals, and the base station cannot completely realize silence of the base station through DRX configuration of the UE. The base station cannot completely realize the turn-off of the base station through the DRX configuration of the UE, that is, the base station still transmits a part of the downlink signal under the active condition, and this part of the signal is transmitted, which leads to an increase in power consumption of the base station, and the UE still needs to receive this part of the signal under the active condition, for example, 1) SSB, PRACH, 2) SI/RA/TC/P-RNTI, PS-RNTI scrambled DCI, 3) SPS PDSCH, 4) CG PUSCH, 5) HARQ-ACK for SPS PDSCH, 6) SR/BFR, so that the UE receives the above signal at DRX inactive Time, and therefore the base station cannot turn off the transmission of the signal during DRX inactive Time of UER, otherwise, UE reception is affected. Therefore, the base station cannot realize the shutdown of data transmission through the existing DRX configuration of the UE, namely cannot realize the dormancy of the base station side.
From the above, the inactive Time of the UE DRX is not effective for some transmissions, and the existing UE DRX configuration is configured through RRC signaling, and the two reconfiguration times are long, so that the DRX configuration of the UE received data cannot be dynamically and flexibly adjusted according to the dynamic change of the traffic load, so as to achieve the maximum energy saving.
In view of this, the present application provides a data transmission method, which can flexibly select a configuration mechanism according to a service load, so as to implement bidirectional dynamic shutdown and reduce power consumption.
The following describes specific embodiments of the present application.
Fig. 3 is a schematic flow chart of a method of data transmission provided herein.
In this embodiment, the network device and the terminal device are taken as an execution body of the interactive schematic to illustrate the method, but the application does not limit the execution body of the interactive schematic. For example, the network device in fig. 3 may also be a chip, a system-on-a-chip, or a processor that supports the method that can be implemented by the network device, or may be a logic module or software that can implement all or part of the functions of the access network device; the terminal device in fig. 3 may also be a chip, a chip system or a processor supporting the method that can be implemented by the terminal device, or may also be a logic module or software that can implement all or part of the functions of the terminal device.
S310, the terminal equipment receives first indication information, wherein the first indication information is used for indicating a first DRX configuration.
In this application, the network device configures the terminal device with one or more DRX configurations for the terminal device not to receive or not to transmit different signals.
One or more DRX configurations may alternatively be understood to correspond to signals, where the correspondence may be understood that different DRX configurations are used to control different signals not to be transmitted or not to be received, may be understood that the signal portions of different DRX configuration controls are the same, or may be understood that the signals of different DRX configuration controls are completely different.
Wherein the first indication information is used for indicating a first DRX configuration, which belongs to one of one or more DRX configurations configured by the network device to the terminal device.
Wherein the first DRX configuration is used to control or indicate the non-transmission or non-reception of the first signal.
In the present application, the first indication information may be carried in the first MAC-CE or the first DCI.
In a possible implementation, the first MAC CE or the first DCI is carried on a multicast or broadcast physical downlink channel.
S320, the terminal device does not receive or transmit the first signal according to the first DRX configuration.
The terminal equipment does not receive the downlink first signal or does not send the uplink first signal according to the first DRX configuration.
In a possible implementation, the terminal device does not receive or transmit the first signal within a first Time window according to the first DRX configuration, e.g. the first Time window is an Inactive Time of the first DRX configuration.
An alternative understanding is that the first DRX configuration controls the terminal device not to receive or not to transmit the first signal within the first time window. At time domain positions outside the first time window, the terminal device may receive or transmit the first signal, or may continue not to receive or transmit the first signal.
In a possible implementation, the terminal device receives or transmits the first signal in a second Time window, e.g. the second Time window is an Active Time of the first DRX configuration.
An alternative understanding is that the first DRX configuration control terminal device may receive or transmit the first signal within the second time window. At time domain positions outside the second time window, the terminal device may not receive or transmit the first signal, or may continue to receive or transmit the first signal.
In this application, the first signal may include at least one of the following four sets of channels by way of example:
The first set of channels includes at least one of the following signals: semi-persistent scheduling physical layer downlink shared channel SPSPSPPDSCH, configuration grant physical uplink shared channel CG PUSCH, hybrid automatic repeat request feedback HARQ-ACK for SPS PDSCH of SPSPPDSCH, scheduling request SR, or beam failure recovery BFR.
The second set of channels includes at least one of the following signals: a physical downlink control channel PDCCH scrambled by a system message radio network temporary identifier SI-RNTI, a physical random access channel PRACH, a PDCCH scrambled by a random access radio network temporary identifier RA-RNTI, or a PDCCH scrambled by a temporary cell radio network temporary identifier TC-RNTI;
the third set of channels includes: paging a PDCCH scrambled by a radio network temporary identifier P-RNTI;
the fourth set of channels includes: synchronization signal/physical broadcast channel block SSB.
It will be appreciated that the first set of channels described above are data dependent channels, the second set of channels are system message dependent channels, and the third and fourth channels may be combined with the second set of channels.
In a possible implementation manner, the terminal device may also not receive or not transmit the second signal according to the second DRX configuration; wherein the second DRX configuration may be a default DRX configuration or a UE-specific DRX configuration configured by the network device through higher layer signaling.
Wherein the second signal comprises at least one of the following signals:
C/CS/SFI/INI/CI/TPC-PUCCH/TPC-PUSCH/TPC-SRS/AI-RNTI scrambled PDCCH, dynamically scheduled PDSCH, DGPUSCH, HARQ-ACK of dynamically scheduled PDSCH, A/P/SP-SRS and A/P/SP-CSI.
In a possible implementation, the terminal device receives second indication information from the network device, the second indication information indicating a second DRX configuration. The second indication information is carried in a first MAC-CE or a first DCI, which carries a downlink physical channel sent by a domain multicast or broadcast mode.
In a possible implementation manner, the first DRX configuration includes a first timer, the first timer is started when the terminal device receives first indication information indicating the first DRX configuration, and when the first timer expires, the terminal device uses the second DRX configuration.
One possible implementation manner is that the physical downlink channel where the first MAC-CE or the first DCI is located is different from the first signal, and/or the physical downlink channel where the first MAC-CE or the first DCI is located is different from the second signal.
An alternative understanding is that the signal carrying the first indication information and the second indication information is not affected by the first signal or the second signal, in other words, the signal carrying the first indication information and the second indication information does not belong to the DRX configuration control signal. That is, the reception of the first indication information or the second indication information is not affected by the limitation of the DRX configuration. That is, even during the inactive state of the DRX configuration, the terminal device receives the first indication information and/or the second indication information, thereby implementing a dynamic handover DRX configuration.
According to the scheme of the embodiment of the application, the terminal equipment can control the sending or receiving states of different signals by adopting different DRX configurations according to the indication of the network equipment, and can flexibly select a configuration mechanism according to the service load, so that the bidirectional dynamic turn-off of the network equipment and the terminal equipment can be realized, and the power consumption is reduced.
Fig. 4 is a further schematic flow chart of a method of data transmission provided herein.
In this embodiment, the network device and the terminal device are taken as an execution body of the interactive schematic to illustrate the method, but the application does not limit the execution body of the interactive schematic. For example, the network device in fig. 4 may also be a chip, a system on a chip, or a processor that supports the method that can be implemented by the network device, or may be a logic module or software that can implement all or part of the functions of the network device; the terminal device in fig. 4 may also be a chip, a chip system or a processor supporting the method that can be implemented by the terminal device, or may also be a logic module or software that can implement all or part of the functions of the terminal device.
S410, the network device sends a message #1 to the terminal device.
Wherein the message #1 comprises a set of configuration information comprising at least one set of configuration information.
The configuration information may be a DRX configuration. In the following embodiments, a DRX configuration is described as an example.
Accordingly, the terminal device receives the message #1 from the network device, i.e., receives the set of configuration information.
In this application, the configuration information set is only a term describing one or more sets of configuration information (DRX configuration) configured by the network device to the terminal device, and the configuration information set may also be directly replaced by at least one configuration information, and the configuration information set may also be replaced by a configuration information set, a configuration information base, or similar terms, which is not limited in this embodiment of the present application.
It can be understood that the configuration information described in this embodiment is the configuration information in the configuration information set. In order to avoid redundancy, the description will not be repeated.
In the present application, in the configuration information set, different DRX configurations are used to control the terminal device not to send and/or not to receive different signals.
An alternative understanding is that the DRX configurations included in the set of configuration information correspond to signals, which correspondence may be understood as different DRX configurations being used to control the transmission or reception status of different signals.
For example, the configuration information set includes a DRX configuration #a, a DRX configuration #b, and a DRX configuration #c, where the DRX configuration #a is used to control not to transmit or not to receive the signal #a, the DRX configuration #b is used to control not to transmit or not to receive the signal #b, and the DRX configuration #c is used to control not to transmit or not to receive the signal #c.
An alternative understanding may be that the correspondence is the same for different DRX configuration control signal parts.
For example, the configuration information set includes a DRX configuration #a, a DRX configuration #b, and a DRX configuration #c, wherein the DRX configuration #a is used for controlling not to transmit or not to receive the signal #a, the DRX configuration #b is used for controlling not to transmit or not to receive the signal #a and the signal #b, and the DRX configuration #c is used for controlling not to transmit or not to receive the signal #a and the signal #c.
The signal is classified into an uplink signal or a downlink signal, and the DRX configuration is used to control the uplink signal not to be transmitted or the DRX configuration is used to control the downlink signal not to be received.
It should be noted that this step is an optional step.
In a possible implementation, the terminal device may pre-configure the set of configuration information, in which case the network device may not send the message #1 to the terminal device.
In yet another possible implementation, the terminal device may store the historically sent configuration information set, in which case the network device may not send the message #1 to the terminal device.
In the present application, the signal of DRX configuration control in the configuration information set includes at least one channel of the first set of channels, the second set of channels, the third channel, or the fourth set of channels.
Wherein the first set of channels comprises at least one of the following signals: semi-persistent scheduling physical layer downlink shared channel SPSPSPS PDSCH, configuration grant physical uplink shared channel CG PUSCH, hybrid automatic repeat request feedback HARQ-ACK for SPS PDSCH of SPS PDSCH, scheduling request SR, or beam failure recovery BFR;
the second set of channels includes at least one of the following signals: a physical downlink control channel PDCCH scrambled by a system message radio network temporary identifier SI-RNTI, a physical random access channel PRACH, a PDCCH scrambled by a random access radio network temporary identifier RA-RNTI, or a PDCCH scrambled by a temporary cell radio network temporary identifier TC-RNTI;
the third set of channels includes: paging a PDCCH scrambled by a radio network temporary identifier P-RNTI;
the fourth set of channels includes: synchronization signal/physical broadcast channel block SSB.
It will be appreciated that the first set of channels described above are data dependent channels, the second set of channels are system message dependent channels, and the third and fourth channels may be combined with the second set of channels.
By way of example and not limitation, message #1 may be RRC-decoded signaling, or RRC common signaling.
Note that when the message #1 is RRC-decoded signaling, the message #1 is configured by the network device to a single UE, and when the message #1 is RRC common signaling, the RRC common signaling is typically placed in SIB, and multiple UEs receive the same signaling.
S420, the network device sends the indication information #1 to the terminal device.
In a possible implementation, the indication information #1 is used to indicate one or more DRX configurations in the configuration information set, for example, DRX configuration #a.
Accordingly, the terminal device receives the indication information #1 from the network device and determines a DRX configuration # a in the configuration information set according to the indication of the indication information #1 (if the indication information #1 indicates a plurality of DRX configurations, e.g., DRX configuration # a, DRX configuration #b, may be determined).
In the present application, the instruction information #1 may be transmitted by multicast or broadcast.
An alternative understanding is that the network device transmits PDCCH/PDSCH at a certain time-frequency resource location and all UEs receive PDCCH/PDSCH to the same time-frequency resource location.
As an example and not by way of limitation, the indication information #1 may be DCI transmitted in a broadcast or multicast manner, or MAC-CE carried in PDSCH transmitted in a broadcast or multicast manner.
The indication information #1 does not belong to the signal of the DRX configuration control. That is, the reception of the indication information #1 is not limited and affected by the DRX configuration. That is, even during the inactive state of the DRX configuration, the UE may normally receive the indication information #1, thereby implementing a dynamic handover DRX configuration.
In the present application, the UE receives the indication information #1, which may be received on the PCell, or on the SCell, or may be received on both the PCell and SCell. The embodiments of the present application are not limited in this regard.
In a possible implementation manner, the indication information #1 is used to indicate the DRX configuration #a in the configuration information set, and a specific indication manner may be indicated in a bit field in the indication information # 1.
As an example, but not by way of limitation, in the indication information #1, a mapping relationship between the value of the bit field and the DRX configuration is set, which can be understood as a correspondence relationship between the value of the bit field and the DRX configuration, in other words, different values of the bit field correspond to different DRX configurations.
It can be appreciated that the DRX configurations are all DRX configurations in the configuration information set.
An indication method of a DRX configuration of the indication information #1 is described below by taking G-DCI or MAC-CE as an example.
The method comprises the following steps:
different values of one bit field or several bits of the G-DCI correspond to different DRX configurations.
For example, the configuration information set includes a DRX configuration #a, a DRX configuration #b, a DRX configuration #c, and a DRX configuration #d, the bit field of the G-DCI is "00", and for different UEs, different DRX configurations may be determined for the bit field value "00". For example, the value corresponds to DRX configuration #a for ue#1 and DRX configuration #b for ue#2.
When the indication information #1 indicates a plurality of DRX configurations (e.g., DRX configuration #a, DRX configuration #b), the bit field value "00" for the UE #1 corresponds to the DRX configuration #a and DRX configuration #b.
Specifically, the UE may determine the correspondence between the bit field value and the DRX configuration according to the index of the mapping DRX configuration or by arranging the DRX configurations according to a certain order, which is not limited in the embodiment of the present application.
The second method is as follows:
bit positions in the G-DCI correspond to different UEs, and bit positions correspond to bit values and correspond to DRX configuration of the UEs.
For example, the configuration information set includes a DRX configuration #a, a DRX configuration #b, a DRX configuration #c, and a DRX configuration #d, and the bit field of the G-DCI is "00 01 10", and for different UEs, corresponding bits may be found, and then the corresponding DRX configuration is determined according to the value of the bits. For example, ue#1 corresponds to the "00" position, and ue#1 determines a corresponding DRX configuration #a according to the value; for another example, ue#2 corresponds to a "01" position, and ue#2 determines a corresponding DRX configuration #c based on the value.
When the indication information #1 indicates a plurality of DRX configurations (e.g., DRX configuration #a, DRX configuration #b), the UE #1 corresponds to the "00" position for the UE #1, and the UE #1 determines the corresponding DRX configuration #a and DRX configuration #b according to the value.
The above examples are merely illustrative, and do not limit the embodiments of the present application in any way.
It should be noted that the foregoing manner is merely an example, and any possible implementation of indicating the configuration information through the bit field may be applicable to the embodiments of the present application.
S430, the terminal device does not receive and/or transmit the signal #a according to the DRX configuration #a.
It will be appreciated that when the indication information #1 indicates a plurality of DRX configurations (e.g., DRX configuration #a, DRX configuration #b), the terminal device does not receive and/or does not transmit signals #a and #b according to the DRX configuration #a and DRX configuration #b.
In the application, the terminal device determines not to receive the downlink signal or not to send the uplink signal according to the indicated DRX configuration.
Wherein, the signal #a is a signal that the DRX configuration #a can control transmission or reception.
When the indication information #1 indicates a plurality of DRX configurations, the terminal device controls the transmission or reception states of a plurality of signals according to the plurality of DRX configurations.
In a possible implementation manner, when the signals controlled by the multiple DRX configurations are not repeated, the terminal device may control transmission or reception of the multiple signals according to the multiple DRX configurations, that is, the corresponding signals are received or transmitted according to different DRX configurations.
In a possible implementation, when multiple DRX configuration control signals are repeated, that is, part of the signals are identical, the same signal may be received or transmitted according to one DRX configuration. In other words, periodic reception or transmission is performed according to onDuration Time and inactive Time in one set of configurations.
The signal may be received or transmitted in one configuration having a relatively small configuration index, in one configuration having a longest inactivity time duration, or in one configuration having a longest DRX cycle. The embodiments of the present application are not limited in this regard.
Fig. 5 illustrates a method schematic diagram of controlling multiple signaling or reception by multiple DRX configurations. As shown in fig. 5, the configuration information set includes three DRX configurations, including a DRX configuration #1, a DRX configuration #2, and a DRX configuration #3, where the three DRX configurations all control DG PUSCH, the DRX configuration #1 also controls DG PDSCH, and the terminal device uses the DRX configuration #1 and the DRX configuration #2 according to the indication information #1, as shown in the figure, the terminal device may perform reception of DG PDSCH in onduration time of the DRX configuration # 1; the terminal device may transmit DG PUSCH at onduration time of DRX configuration # 2.
It can be understood that when the terminal device transmits the uplink DG PUSCH, if it is determined that the DRX configuration with the longest DRX cycle is DRX configuration #2, the DG PUSCH is transmitted in onduration time of the DRX configuration # 2.
It should be understood that the foregoing is merely illustrative, and the terminal device may also perform the transmission of the foregoing signal according to a configuration with a relatively small configuration index, or perform the transmission of the foregoing signal according to a configuration with a longest duration of inactivity, which is not limited in the embodiments of the present application.
In a possible implementation, when multiple DRX configuration control signals are repeated, that is, part of the signals are identical, the same signal may be received or transmitted according to two DRX configurations. In other words, periodic reception or transmission is performed according to the onDuration Time and the inactive Time in the two sets of configurations.
Fig. 6 illustrates another method schematic diagram of multiple DRX configurations to control multiple signaling or reception. As shown in fig. 6, the configuration information set includes three DRX configurations including DRX configuration #1, DRX configuration #2, DRX configuration #3, wherein all three DRX configurations control DG PUSCH. The terminal device uses the DRX configuration #2 and the DRX configuration #3 according to the indication information #1, as shown in the figure, the terminal device may perform DG PUSCH transmission in both the DRX configuration #2 and the onduration time of the DRX configuration # 3.
It can be understood that when the terminal device transmits the uplink DG PUSCH, if it is determined that the DRX configuration with the longest DRX cycle is DRX configuration #3, the DG PUSCH is transmitted in onduration time of the DRX configuration # 3.
It should be understood that the foregoing is merely illustrative, and that no limitations are intended to the embodiments of the present application.
S440, the terminal device does not receive and/or does not transmit the signal #y according to the DRX configuration #y.
When the first condition is met, DRX configuration #a may be understood as disabled, and signal #y is not received and/or not transmitted using DRX configuration #y.
It is understood that when the indication information #1 indicates a plurality of DRX configurations (e.g., DRX configuration #a, DRX configuration #b), the DRX configuration #a and DRX configuration #b may be understood as being disabled when the first condition is satisfied, the signal #y is not received and/or not transmitted using the DRX configuration #y.
The DRX configuration #y is an original DRX configuration or a default DRX configuration.
Wherein the signal #y includes at least one of the following signals: C/CS/SFI/INI/CI/TPC-PUCCH/TPC-PUSCH/TPC-SRS/AI-RNTI scrambled PDCCH, dynamically scheduled PDSCH, DGPUSCH, HARQ-ACK of dynamically scheduled PDSCH, A/P/SP-SRS and A/P/SP-CSI.
In a possible implementation, the terminal device receives indication information #2 from the network device, the indication information #2 indicating the DRX configuration #y.
In a possible implementation, the DRX configuration #a includes a first timer, and when the first timer expires, the DRX configuration #y may be activated.
In a possible implementation manner, the terminal device sends a specific signal to the network device, and the network device sends acknowledgement information after receiving the specific signal to confirm that the terminal device can switch to the DRX configuration #y.
According to the scheme of the embodiment of the application, the terminal equipment can control the sending or receiving states of different signals by adopting different DRX configurations according to the indication of the network equipment, and can flexibly select a configuration mechanism according to the service load, so that the bidirectional dynamic turn-off of the network equipment and the terminal equipment can be realized, and the power consumption is reduced.
