Description

Method and device for intercepting energy-saving signal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for intercepting an energy saving signal.
Background
In the prior art, on the premise of ensuring effective transmission of data, a mechanism for saving power consumption of a UE (User Equipment) is designed for reducing power consumption of a terminal, and the mechanism is called DRX (Discontinuous Reception).
Although this has a certain effect on the delay of data transmission, if the delay does not affect the user experience, it is meaningful to perform DRX considering the more important power consumption of the UE.
A typical DRX cycle is shown in fig. 1. In this figure, the time period marked "On Duration" is the time when the UE monitors the downlink PDCCH subframe, during which time the UE is awake. The period of time identified as "Opportunity for DRX" is the DRX sleep time, i.e. the time the UE goes to sleep without monitoring PDCCH subframes for power saving. As can be seen from this figure, the longer the time for DRX sleep, the lower the power consumption of the UE, but correspondingly, the delay of traffic transmission will increase.
However, in the DRX implementation process, the UE is awakened in the "On Duration" interval of each DRX cycle and monitors the downlink PDCCH subframes. However, data transmission is not required between each "On Duration" interval UE and the network side device, and thus, the UE power is also consumed by monitoring the downlink PDCCH subframe in the "On Duration" interval where data transmission is not required.
Referring to fig. 2, in order to further reduce power consumption of the terminal device, researchers have introduced the concept of a power saving signal in their research. When the method is implemented specifically, the network side equipment wakes up the terminal to execute the PDCCH interception operation through the energy-saving signal so as to complete data receiving, and when data receiving and sending do not exist, the terminal can be in a sleep state, so that the power consumption is reduced. There are two energy-saving schemes.
The first method is as follows: whether to perform subsequent PDCCH interception is determined by detecting whether a power-saving signal exists.
The network side equipment sends an energy-saving signal to the terminal at a pre-configured resource position, and then the UE periodically detects the resource position of the energy-saving signal. If a power saving signal is detected, the UE will perform PDCCH interception, otherwise the UE will not intercept PDCCH.
The second method comprises the following steps: whether the PDCCH needs to be monitored by waking up is judged by decoding the content of the energy-saving signal.
The network side equipment sends an energy-saving signal to the terminal at a pre-configured resource position, and then the UE periodically detects the resource position of the energy-saving signal. After receiving the energy-saving signal, the UE decodes the energy-saving signal to obtain the monitoring PDCCH indication information sent by the network side equipment, if the energy-saving signal informs the UE to execute the waking operation, the UE wakes up to monitor the PDCCH, otherwise, the UE does not monitor the PDCCH.
Currently, when an energy-saving signal is transmitted by using a DCI (Downlink control information), the DCI carried by the PDCCH has a certain error rate, which may cause false detection of the energy-saving signal. Further, after the power saving signal is detected by mistake, the terminal may lose the data to be received.
For example, the current power saving signal indicates that the UE wakes up, but the UE checks an error, so that the content of the power saving signal cannot be known; or due to the interference problem, the UE does not receive the energy-saving signal, so that the UE does not send the energy-saving signal for the network side device at this time, and does not need to wake up, thereby losing the PDCCH.
In summary, in the prior art, a PDCCH which needs to be monitored is lost by a terminal due to a false detection of an energy saving signal, thereby causing a data loss.

The first method is as follows: whether to perform subsequent PDCCH interception is determined by detecting whether a power-saving signal exists.
The network side equipment sends an energy-saving signal to the terminal at a pre-configured resource position, and then the UE periodically detects the resource position of the energy-saving signal. If a power saving signal is detected, the UE will perform PDCCH interception, otherwise the UE will not intercept PDCCH.
The second method comprises the following steps: whether the PDCCH needs to be monitored by waking up is judged by decoding the content of the energy-saving signal.
The network side equipment sends an energy-saving signal to the terminal at a pre-configured resource position, and then the UE periodically detects the resource position of the energy-saving signal. After receiving the energy-saving signal, the UE decodes the energy-saving signal to obtain the monitoring PDCCH indication information sent by the network side equipment, if the energy-saving signal informs the UE to execute the waking operation, the UE wakes up to monitor the PDCCH, otherwise, the UE does not monitor the PDCCH.
In the current NR (New Radio, New air interface) discussion, it has been agreed to use DCI to transmit the energy-saving signal, but DCI carried by PDCCH has a certain bit error rate, so that there is a risk of false detection of the energy-saving signal. Further, after the power saving signal is detected by mistake, the terminal may lose the data to be received, or wake up the terminal at a resource location where the data is not required to be received, which wastes resources.
In order to solve the above problem, an embodiment of the present invention provides a scheme for intercepting an energy saving signal, where in implementation of the scheme, a terminal intercepts the energy saving signal at a pre-configured time-frequency resource location; the energy-saving signal listening result is fed back to the network side equipment. Therefore, the network side equipment can determine whether the terminal misdetects the energy-saving signal according to the energy-saving signal interception result fed back by the terminal, and the network side equipment can determine whether the terminal can successfully receive the data, namely the network side equipment can definitely know the data lost by the terminal; furthermore, the network side device may take measures to retransmit the data of the terminal to the terminal that wrongly detects the energy-saving signal after determining that the terminal wrongly detects the energy-saving signal, so as to reduce the probability that the terminal loses the data that needs to be received, and improve the stability of data transmission between the terminal and the network side device.
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 3, an embodiment of the present invention provides a system for listening to a power saving signal, where the system includes: a terminal 300 and a network side device 301;
a terminal 300, configured to listen to an energy saving signal at a pre-configured time-frequency resource location; and feeding back the energy-saving signal interception result to the network side equipment.
A network side device 301, configured to configure a resource for intercepting an energy saving signal for a terminal, where the energy saving signal indicates whether the terminal performs an energy saving operation; and receiving an energy-saving signal interception result fed back by the terminal.
In the specific implementation of the embodiment of the invention, network side equipment configures resources for a terminal to intercept an energy-saving signal, wherein the energy-saving signal indicates whether the terminal performs energy-saving operation; then the terminal monitors the energy-saving signal at a pre-configured time frequency resource position; and feeding back the energy-saving signal interception result to the network side equipment, and further receiving the energy-saving signal interception result fed back by the terminal by the network side equipment. Therefore, the network side equipment can determine whether the terminal misdetects the energy-saving signal according to the energy-saving signal interception result fed back by the terminal, and the network side equipment can determine whether the terminal can successfully receive the data, namely the network side equipment can definitely know the data lost by the terminal; furthermore, the network side device may take measures to retransmit the data of the terminal to the terminal that wrongly detects the energy-saving signal after determining that the terminal wrongly detects the energy-saving signal, so as to reduce the probability that the terminal loses the data that needs to be received, and improve the stability of data transmission between the terminal and the network side device.
Two energy saving signals for instructing the terminal to wake up for PDCCH monitoring can be determined from the above, so the energy saving signals in the first and second schemes are described in detail below as an example.
The first scheme is as follows: whether to perform subsequent PDCCH interception is determined by detecting whether a power-saving signal exists.
In the scheme, when the network side equipment needs to send downlink data to the terminal, the energy-saving signal is sent to the terminal at a time domain resource position preset for monitoring the energy-saving signal;
correspondingly, the terminal automatically wakes up at the time domain resource position which is possible to receive the energy saving signal in each period, and listens the energy saving signal which is possible to be sent by the network side equipment.
If the terminal receives the energy-saving signal at a time domain resource position for monitoring the energy-saving signal, the terminal monitors a PDCCH (physical downlink control channel) at an 'on duration' interval of a DRX (discontinuous reception) after the time domain resource position for receiving the energy-saving signal and receives downlink data sent by network side equipment;
otherwise, the terminal will perform energy saving operation.
In specific implementation, first, a network side device needs to configure a resource for intercepting an energy saving signal for a terminal, where the energy saving signal indicates whether the terminal performs an energy saving operation.
Specifically, the configuring, by the network side device, the resource for intercepting the energy-saving signal for the terminal includes:
and monitoring the time-frequency resource position of the energy-saving signal, the search space of the energy-saving signal, the aggregation level of the energy-saving signal, the transmission period of the energy-saving signal and the transmission times of the energy-saving signal.
The time-frequency resource position of the energy-saving signal is the time-frequency resource position of the energy-saving signal which needs to be monitored by the terminal;
the search space of the energy-saving signal refers to a resource position of a PDCCH for detecting the energy-saving signal or an alternative resource format of the PDCCH for detecting the energy-saving signal;
the aggregation level of the power saving signals refers to the number of continuous CEEs occupied by the power saving signals;
the sending period of the energy-saving signal refers to the period duration of the energy-saving signal sent by the network side equipment;
the sending times of the energy-saving signals are the sending times of the energy-saving signals in a period configured by the network side equipment.
Wherein, the terminal performs energy-saving operation including: the terminal does not listen to the PDCCH, the terminal does not listen to the PDCCH at the DRX on (discontinuous reception active) time, and the DRX on duration Timer (duration Timer for discontinuous transmission) is not operated.
After network side equipment configures resources for monitoring energy-saving signals for a terminal, if the network side equipment has energy-saving signals needing to be sent to the terminal, the energy-saving signals are sent to the terminal at configured time-frequency resource positions for monitoring the energy-saving signals;
correspondingly, the terminal monitors the energy-saving signal at the time-frequency resource position of the energy-saving signal configured by the network side equipment.
In specific implementation, after receiving an energy saving signal sent by a network side device, a terminal monitors a PDCCH.
And the terminal feeds back the energy-saving signal interception result to the network side equipment through MAC CE signaling or PUCCH.
In specific implementation, when the terminal feeds back an energy-saving signal interception result to the network side device through MAC CE signaling or PUCCH, the terminal feeds back indication information for indicating whether an energy-saving signal is received to the network side device; or feeding back indication information for indicating whether to monitor the PDCCH to the network side equipment through MAC CE signaling or PUCCH, wherein the indication information whether to monitor the PDCCH physical downlink control channel is determined according to whether the energy-saving signal is received.
If the terminal feeds back the energy-saving signal interception result to the network side equipment through the MAC CE signaling, the MAC CE signaling carries part or all of the following parameters:
cell ID and BWP ID of the Cell, the number of the energy-saving signal group corresponding to the terminal, UE ID carried by the energy-saving signal, PCI and CG ID of the Cell;
if the terminal feeds back the energy-saving signal interception result to the network side equipment through the PUCCH, the indication information carries part or all of the following parameters:
cell ID, BWP ID, number of energy-saving signal group corresponding to terminal, UE ID carried by energy-saving signal.
Correspondingly, the network side equipment receives the energy-saving signal interception result fed back by the terminal through the MAC CE signaling or the PUCCH.
Further, after receiving the energy-saving signal interception result fed back by the terminal, the network side device determines that the energy-saving signal interception result intercepted by the terminal is wrong according to the energy-saving signal interception result fed back by the UE, and then executes retransmission of the energy-saving signal.
The first embodiment is as follows: and the energy-saving signal is sent only once in the energy-saving signal period configured by the network side equipment.
In specific implementation, when the terminal is instructed by the energy-saving signal to receive data issued by the network-side device, the network-side device first configures resources for intercepting the energy-saving signal for the terminal, where the resources of the energy-saving signal configured by the network-side device include a time-frequency resource location of the energy-saving signal intercepted by the terminal, a search space of the energy-saving signal, an aggregation level of the energy-saving signal, a transmission cycle of the energy-saving signal, transmission times of the energy-saving signal, and the like.
Therefore, when the time-frequency resource position for monitoring the energy-saving signal arrives, the terminal wakes up and monitors the energy-saving signal at the time-frequency resource position, monitors the PDCCH according to the indication of the energy-saving signal sent by the network side equipment, and receives the data sent by the network side equipment.
Note that the energy saving signal may be a set of sequences based on a sequence format, or may be a PDCCH transmitted in a DCI format.
During specific implementation, when downlink data exists in network side equipment and needs to be sent to a terminal, the network side equipment sends an energy-saving signal to the terminal on a configured time-frequency resource for the terminal to monitor the energy-saving signal;
correspondingly, the terminal periodically wakes up and monitors the energy-saving signal on the time-frequency resource for monitoring the energy-saving signal, and when the terminal receives the energy-saving signal, the terminal determines that the PDCCH needs to be monitored in the DRX period and receives data issued by the network side equipment; and when the terminal does not receive the energy-saving signal on the time-frequency resource for intercepting the energy-saving signal, determining that the energy-saving operation can be performed.
It should be noted that the energy saving operation referred to in this application includes: not monitoring PDCCH, not monitoring PDCCH at DRXon time, not running DRX on duration Timer.
Furthermore, the terminal monitors the energy-saving signal at the time-frequency resource position of the energy-saving signal configured by the network side equipment, and feeds back the energy-saving signal monitoring result to the network side equipment.
In specific implementation, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling; or the terminal can feed back the energy-saving signal listening result to the network side equipment through the PUCCH.
The following description will be continued with respect to the above two feedback manners, respectively.
Firstly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling.
In specific implementation, a new MAC CE signaling needs to be defined first, and the terminal feeds back the energy saving signal interception result to the network side device through the newly defined MA C CE signaling.
Further, when feeding back the energy saving signal monitoring result to the network side device, the terminal may feed back whether the energy saving signal is received or not to the network side device, and may also feed back whether the PDCCH is monitored or not to the network side device.
In a specific implementation, referring to fig. 4, when a new MAC CE signaling is used to feed back an energy saving signal interception result to a network side device in fig. 4, a set of local channel identity (logical channel identity) (6 bits) is set for the MAC CE signaling, so that the MAC CE signaling is different from an existing MAC CE signaling, and the network side device determines whether the MAC CE signaling is the MAC CE signaling used to feed back the energy saving signal interception result by identifying the LCID.
And the bit before the LCID for marking the MAC CE signaling is used as a flag bit Ind for indicating the energy-saving signal interception result. In specific implementation, when the terminal feeds back the energy-saving signal feedback result to the network side device through the MAC CE signaling, the set flag bit may take different bit values to represent different energy-saving signal interception results.
For example:
(1) when the terminal feeds back the energy-saving signal interception result to the network side equipment, the terminal can feed back whether the energy-saving signal is received or not to the network side equipment;
assuming that a flag bit Ind indicating an energy-saving signal interception result in the MAC CE signaling is "1", indicating that the terminal receives an energy-saving signal sent by a network side device;
when the flag bit Ind indicating the energy-saving signal interception result in the MAC CE signaling is "0", it indicates that the terminal fails to receive the energy-saving signal sent by the network side device;
thus, when the terminal needs to monitor the arrival of the time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the flag bit Ind in the MAC CE is valued as "1" and the MAC CE signaling is sent to the network side device; and if the terminal does not receive the energy-saving signal, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment.
(2) When feeding back the energy-saving signal monitoring result to the network side equipment, the terminal can feed back whether to monitor the PDCCH to the network side equipment;
assuming that a flag bit Ind indicating an energy-saving signal monitoring result in the MAC CE signaling is "1", it indicates that the terminal will monitor the PDCCH on a subsequent PUCCH opportunity;
when the flag bit Ind indicating the energy-saving signal monitoring result in the MAC CE signaling is "0", it indicates that the terminal will not monitor the PDCCH on the subsequent PUCCH opportunity, i.e., perform energy-saving operation;
thus, when the terminal needs to monitor the time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the terminal is determined to indicate the terminal to monitor the PDCCH and receive downlink data, the flag bit Ind in the MAC CE signaling is set to be 1, and the MAC CE signaling is sent to the network side equipment; and if the terminal does not receive the energy-saving signal, dereferencing the flag bit Ind in the MAC CE signaling to be 0, and sending the MAC CE signaling to the network side equipment.
And when the terminal feeds back the energy-saving signal interception result to the network side equipment, the terminal sends the MAC CE signaling on the available uplink resource after intercepting the time domain resource position of the energy-saving signal.
In a specific implementation process, the available uplink resource of the MAC CE signaling that can be used for feeding back the energy saving signal interception result may be a configuration authorization resource, or an uplink resource configured by the network side device;
if the available uplink resource is a configuration authorization resource, the configuration authorization resource is a periodically existing UL (uplink) resource configured by the network side device, and the network side device also configures contents such as a Modulation Coding Scheme (MCS) and a Transport Block (TB) Block size of a corresponding resource.
And if the available uplink resource is the uplink resource configured by the network side equipment, the uplink resource configured by the network side equipment is the uplink resource with the time domain offset set to the distance from the time domain position of the energy-saving signal.
Further, if the terminal feeds back the energy saving signal interception result to the network side device through the MAC CE signaling, the MAC CE signaling carries part or all of the following parameters:
cell ID and BWP ID of the Cell, number of energy-saving signal group corresponding to the terminal, UE ID carried by the energy-saving signal, PCI and CG ID of the Cell.
Therefore, the network side device can determine the terminal reporting the energy-saving signal interception result according to the parameter information carried in the MAC CE signaling, and then can execute retransmission of the energy-saving signal after determining that the energy-saving signal interception result fed back by the terminal is that the terminal fails to receive the energy-saving signal or the terminal does not intercept the PDCCH, and resend the energy-saving signal to the terminal.
For example:
(1) when the terminal feeds back the energy-saving signal interception result to the network side equipment, the terminal can feed back whether the energy-saving signal is received or not to the network side equipment;
assuming that a flag bit Ind indicating an energy-saving signal interception result in the MAC CE signaling is "1", indicating that the terminal receives an energy-saving signal sent by a network side device;
when the flag bit Ind indicating the energy-saving signal interception result in the MAC CE signaling is "0", it indicates that the terminal fails to receive the energy-saving signal sent by the network side device;
thus, when the network side equipment needs to send downlink data to the terminal, the energy-saving signal is sent to the terminal at the configured time-frequency resource position for monitoring the energy-saving signal, and then the terminal monitors the energy-saving signal at the time-frequency resource position for monitoring the energy-saving signal;
if the terminal receives the energy-saving signal, the flag bit Ind in the MAC CE is set to be 1, and the MAC CE signaling is sent to the network side equipment; then, after receiving an MAC CE signal which is sent by a terminal and used for feeding back an energy-saving signal interception result, the network side equipment inquires whether an indication terminal receives an energy-saving signal flag bit Ind in an MAC CE signaling; when the network side equipment determines that the flag bit Ind is '1', determining that the terminal receives an energy-saving signal;
if the terminal does not receive the energy-saving signal, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment; then, after receiving an MAC CE signal which is sent by a terminal and used for feeding back an energy-saving signal interception result, the network side equipment inquires whether an indication terminal receives an energy-saving signal flag bit Ind in an MAC CE signaling; when the network side equipment determines that the flag bit Ind is '0', it is determined that the terminal cannot receive the energy-saving signal, and the network side equipment executes retransmission of the energy-saving signal.
(2) When feeding back the energy-saving signal monitoring result to the network side equipment, the terminal can feed back whether to monitor the PDCCH to the network side equipment;
assuming that a flag bit Ind indicating an energy-saving signal monitoring result in the MAC CE signaling is "1", it indicates that the terminal will monitor the PDCCH on a subsequent PUCCH opportunity;
when the flag bit Ind indicating the energy-saving signal monitoring result in the MAC CE signaling is "0", it indicates that the terminal will not monitor the PDCCH on the subsequent PUCCH opportunity, i.e., perform energy-saving operation;
thus, when the network side equipment needs to send downlink data to the terminal, the energy-saving signal is sent to the terminal at the configured time-frequency resource position for monitoring the energy-saving signal, and then the terminal monitors the energy-saving signal at the time-frequency resource position for monitoring the energy-saving signal;
if the terminal receives the energy-saving signal and determines that the PDCCH needs to be monitored on the subsequent PUCCH opportunity, the flag bit Ind in the MAC CE is set to be 1, and the MAC CE signaling is sent to the network side equipment; then, after receiving a MAC CE signal which is sent by the terminal and used for feeding back the energy-saving signal interception result, the network side equipment queries whether the indication terminal receives an energy-saving signal flag bit Ind in an MAC CE signaling; when the network side equipment determines that the flag bit Ind is '1', determining that the terminal receives an energy-saving signal;
if the terminal does not receive the energy-saving signal, determining that the PDCCH is not monitored on the subsequent PUCCH opportunity, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment; then, after receiving a MAC CE signal which is sent by the terminal and used for feeding back the energy-saving signal interception result, the network side equipment queries whether the indication terminal receives an energy-saving signal flag bit Ind in an MAC CE signaling; when the network side equipment determines that the flag bit Ind is '0', the terminal is determined not to monitor the PDCCH, and the network side equipment performs retransmission of the energy-saving signal.
And secondly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the PUCCH.
In specific implementation, when feeding back the energy saving signal listening result to the network side device through the PUCCH, the terminal may feed back whether the energy saving signal is received or not to the network side device, and may also feed back whether the PDCCH is monitored or not to the network side device.
The terminal may feed back, to the network side device, the indication information indicating that the terminal receives the energy saving signal through the PUCCH via the feedback signal in the HARQ feedback format.
Further, the method for the terminal to feed back the energy-saving signal listening result to the network side device through the PUCCH includes the following three ways:
the first method is as follows: the terminal sends the indication information on a PUCCH pre-configured by the network side equipment;
the second method comprises the following steps: the terminal sends the indication information on a PUCCH spaced by K time slots or K symbols from the time domain resource position of the energy-saving signal;
wherein K is a positive integer and is notified by the network side device, or K is preconfigured, or K is determined according to SCS;
the third method comprises the following steps: and the terminal sends the indication information on a PUCCH with a set time interval away from the time domain resource position of the energy-saving signal.
It should be noted that, if the terminal feeds back the energy saving signal listening result to the network side device through the PUCCH, the indication information carries part or all of the following parameters:
cell ID and BWP ID of the Cell, number of energy-saving signal group corresponding to the terminal, and UE ID carried by the energy-saving signal.
After the terminal sends the HARQ feedback signal contained in the energy-saving signal interception result to the network side equipment through the PUCCH, the network side equipment receives and decodes the HARQ feedback signal, and determines whether the terminal sending the HARQ feedback signal successfully receives the energy-saving signal according to the indication information obtained by decoding.
In the above embodiment, the number of times of transmission in the energy saving signal period in the energy saving signal resource configured for the terminal by the network side device is one.
In a specific implementation process, in order to improve the probability of receiving the energy-saving signal by the terminal, the network side device may configure the energy-saving signal to send the energy-saving signal for multiple times within the energy-saving signal period.
In specific implementation, the resources of the energy saving signal configured by the network side device include a time-frequency resource location of the terminal for intercepting the energy saving signal, a search space of the energy saving signal, an aggregation level of the energy saving signal, a transmission period of the energy saving signal, transmission times of the energy saving signal, and the like.
It should be noted that, when the network side device configures energy-saving signal resources for the terminal, the number of times of sending the energy-saving signal is greater than or equal to 2 times; thus, the network side device needs to configure corresponding resources for each energy saving signal in the energy saving signal transmission period.
Therefore, when the time-frequency resource position for monitoring the energy-saving signal arrives, the terminal wakes up and monitors the energy-saving signal at the time-frequency resource position, and determines whether to monitor the PDCCH according to whether to receive the energy-saving signal sent by the network side equipment, namely, receives the data sent by the network side equipment.
During specific implementation, when downlink data exists in network side equipment and needs to be sent to a terminal, the network side equipment sends an energy-saving signal to the terminal on a configured time-frequency resource for the terminal to monitor the energy-saving signal;
correspondingly, the terminal periodically wakes up and monitors the energy-saving signal on the time-frequency resource for monitoring the energy-saving signal, and when the terminal receives the energy-saving signal, the terminal determines that the PDCCH needs to be monitored on the resource position of the PDCCH needing to be monitored in the DRX period, and receives data sent by the network side equipment;
and when the terminal does not receive the energy-saving signal on the time-frequency resource for intercepting the energy-saving signal, determining that the energy-saving operation can be performed.
It should be noted that the energy saving operation referred to in this application includes: not monitoring PDCCH, not monitoring PDCCH at DRXon time, not running DRX on duration Timer.
Furthermore, the terminal monitors the energy-saving signal at the time-frequency resource position of the energy-saving signal configured by the network side equipment, and feeds back the energy-saving signal monitoring result to the network side equipment.
In specific implementation, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling; or the terminal can feed back the energy-saving signal listening result to the network side equipment through the PUCCH.
The description will be continued with respect to the two feedback manners, respectively.
Firstly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling.
In specific implementation, a new MAC CE signaling needs to be defined first, and the terminal feeds back the energy saving signal interception result to the network side device through the newly defined MA C CE signaling.
Further, when feeding back the energy saving signal monitoring result to the network side device, the terminal may feed back whether the energy saving signal is received or not to the network side device, and may also feed back whether the PDCCH is monitored or not to the network side device.
It should be noted that the format of the MAC CE signaling is the same as that in the foregoing embodiment, and therefore, the description is omitted.
In specific implementation, the network side device determines the energy saving signal feedback result fed back by the terminal according to the value of the flag bit Ind indicating the energy saving signal interception result in the MAC CE signaling.
Correspondingly, the terminal sends a feedback signal to the network side equipment every time the terminal listens for the energy-saving signal.
When the network side device repeatedly sends the energy-saving signal for multiple times, in order to reduce energy loss of the terminal, the terminal can receive the energy-saving signal and then does not listen to subsequent energy-saving signals.
The following description will be made in conjunction with examples.
For example:
(1) when the terminal feeds back the energy-saving signal interception result to the network side equipment, whether the energy-saving signal is received or not can be fed back to the network side equipment, and the number of times of sending the energy-saving signal in the period configured by the network side equipment is 3;
assuming that a flag bit Ind indicating an energy-saving signal interception result in the MAC CE signaling is "1", indicating that the terminal receives an energy-saving signal sent by a network side device;
when the flag bit Ind indicating the energy-saving signal interception result in the MAC CE signaling is "0", it indicates that the terminal fails to receive the energy-saving signal sent by the network side device;
thus, when the terminal needs to monitor the arrival of the first time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the flag bit Ind in the MAC CE is valued to "1" and the MAC CE signaling is sent to the network side device, and meanwhile, the subsequent energy-saving signal is not monitored; if the terminal does not receive the energy-saving signal, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment;
meanwhile, whether the number of the time domain resource positions of the intercepted energy-saving signals reaches the energy-saving signal sending times in the period configured by the network side equipment is judged; the energy-saving signal is only intercepted once at present, the number of the time domain resource positions of the intercepted energy-saving signal is smaller than the energy-saving signal in the period configured by the network side equipment, and the terminal is determined to continue intercepting the subsequent energy-saving signal;
when the terminal needs to monitor the arrival of the second time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the flag bit Ind in the MAC CE is set to be 1, the MAC CE signaling is sent to the network side equipment, and meanwhile, the subsequent energy-saving signal is not monitored; if the terminal does not receive the energy-saving signal, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment;
meanwhile, whether the number of the time domain resource positions of the intercepted energy-saving signals reaches the energy-saving signal sending times in the period configured by the network side equipment is judged; the terminal finishes the energy-saving signal interception twice currently, the number of the time domain resource positions of the intercepted energy-saving signals is smaller than the energy-saving signals in the period configured by the network side equipment, and the terminal is determined to continue intercepting the subsequent energy-saving signals;
when the terminal needs to monitor the arrival of the third time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the flag bit Ind in the MAC CE is set to be 1, and the MAC CE signaling is sent to the network side equipment; meanwhile, subsequent energy-saving signals are not monitored; if the terminal does not receive the energy-saving signal, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment;
meanwhile, whether the number of the time domain resource positions of the intercepted energy-saving signals reaches the energy-saving signal sending times in the period configured by the network side equipment is judged; the energy-saving signal interception is finished three times at present by the terminal, the number of the time domain resource positions of the intercepted energy-saving signal is not less than the energy-saving signal in the period configured by the network side equipment, and the terminal is determined to stop intercepting the energy-saving signal.
(2) When feeding back the energy-saving signal monitoring result to the network side equipment, the terminal can feed back whether to monitor the PDCCH to the network side equipment, and the energy-saving signal transmission frequency in the period configured by the network side equipment is 6 times;
assuming that a flag bit Ind indicating an energy-saving signal monitoring result in the MAC CE signaling is "1", it indicates that the terminal will monitor the PDCCH on a subsequent PUCCH opportunity;
when the flag bit Ind indicating the energy-saving signal monitoring result in the MAC CE signaling is "0", it indicates that the terminal will not monitor the PDCCH on the subsequent PUCCH opportunity, i.e., perform energy-saving operation;
thus, when the terminal needs to monitor the time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the terminal determines that the network side equipment indicates the terminal to monitor the PDCCH and receive downlink data, the flag bit Ind in the MAC CE signaling is set to be 1, the MAC CE signaling is sent to the network side equipment, and meanwhile, the subsequent energy-saving signal is not monitored; if the terminal does not receive the energy-saving signal, the flag bit Ind in the MAC CE signaling is set to be 0, and the MAC CE signaling is sent to the network side equipment;
meanwhile, whether the number of the time domain resource positions of the intercepted energy-saving signals reaches the energy-saving signal sending times in the period configured by the network side equipment is judged; the energy-saving signal is only intercepted once at present, the number of the time domain resource positions of the intercepted energy-saving signal is smaller than the energy-saving signal in the period configured by the network side equipment, and the terminal is determined to continue intercepting the subsequent energy-saving signal;
when the terminal needs to monitor the second time-frequency resource position of the energy-saving signal, if the terminal receives the energy-saving signal, the terminal determines that the network side equipment indicates the terminal to monitor the PDCCH and receive downlink data, the flag bit Ind in the MAC CE signaling is set to be 1, the MAC CE signaling is sent to the network side equipment, and meanwhile, the subsequent energy-saving signal is not monitored; if the terminal does not receive the energy-saving signal, the flag bit Ind in the MAC CE signaling is set to be 0, and the MAC CE signaling is sent to the network side equipment;
meanwhile, whether the number of the time domain resource positions of the intercepted energy-saving signals reaches the energy-saving signal sending times in the period configured by the network side equipment is judged; the terminal finishes the energy-saving signal interception twice currently, the number of the time domain resource positions of the intercepted energy-saving signals is smaller than the energy-saving signals in the period configured by the network side equipment, and the terminal is determined to continue intercepting the subsequent energy-saving signals;
in this way, after the terminal senses the energy-saving signal before the number of the time domain resource positions of the sensed energy-saving signal reaches the energy-saving signal sending times in the period configured by the network side equipment, the terminal does not sense the subsequent energy-saving signal.
Therefore, the energy-saving signal can be sent for multiple times in the embodiment of the invention, the probability of receiving the energy-saving signal by the terminal is increased, and meanwhile, after the terminal receives the energy-saving signal, the energy loss of the terminal can be reduced without monitoring the subsequent energy-saving signal.
And secondly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the PUCCH.
In specific implementation, when feeding back the energy saving signal listening result to the network side device through the PUCCH, the terminal may feed back whether the energy saving signal is received or not to the network side device, and may also feed back whether the PDCCH is monitored or not to the network side device.
The terminal may feed back, to the network side device, the indication information indicating that the terminal receives the energy saving signal through the PUCCH via the feedback signal in the HARQ feedback format.
Further, the method for the terminal to feed back the energy-saving signal listening result to the network side device through the PUCCH includes the following three ways:
the first method is as follows: the terminal sends the indication information on a PUCCH pre-configured by the network side equipment;
the second method comprises the following steps: the terminal sends the indication information on a PUCCH spaced by K time slots or K symbols from the time domain resource position of the energy-saving signal;
wherein K is a positive integer and is notified by the network side device, or K is preconfigured, or K is determined according to SCS;
the third method comprises the following steps: and the terminal sends the indication information on a PUCCH with a set time interval away from the time domain resource position of the energy-saving signal.
It should be noted that, if the terminal feeds back the energy saving signal listening result to the network side device through the PUCCH, the indication information carries part or all of the following parameters:
cell ID and BWP ID of the Cell, number of energy-saving signal group corresponding to the terminal, and UE ID carried by the energy-saving signal.
After the terminal sends the HARQ feedback signal contained in the energy-saving signal interception result to the network side equipment through the PUCCH, the network side equipment receives and decodes the HARQ feedback signal, and determines whether the terminal sending the HARQ feedback signal successfully receives the energy-saving signal according to the indication information obtained by decoding.
Example two: and the terminal decodes the energy-saving signal and determines whether to carry out PDCCH interception according to the indication information obtained by decoding the energy-saving signal.
In specific implementation, the manner in which the network side device configures the energy-saving signal resource for the terminal is similar to that in the first embodiment, and therefore, details are not repeated.
Specifically, when the scheme in the second embodiment is implemented specifically, the network side device sends the energy-saving signal to the terminal at a pre-configured resource location, and then the UE periodically detects the resource location of the energy-saving signal, and when the terminal decodes the received energy-saving signal and determines to perform the energy-saving operation according to the indication information obtained by decoding the energy-saving signal, the PDCCH is not monitored, otherwise, the PDCCH is monitored.
That is, in this scheme, the network side device will send the energy saving signal to the terminal in each energy saving signal period; accordingly, the terminal has a power saving signal to be listened to in each power saving signal period.
In the scheme, the terminal can feed back the energy-saving signal interception result to the network side equipment through MAC CE signaling or PUCCH.
The terminal feeds back the energy-saving signal monitoring result to the network side equipment through MAC CE signaling or PUCCH, wherein the energy-saving signal monitoring result can be indication information indicating whether the received energy-saving signal is successfully decoded or indicating whether the PDCCH is monitored;
the indication information of whether to monitor the PDCCH is determined according to the indication information in the successfully decoded energy-saving signal.
Specifically, when the terminal receives and decodes the energy-saving signal, and the indication information of the decoded energy-saving signal indicates the terminal to wake up and monitor the PDCCH, the PDCCH is determined to be monitored;
when the terminal receives and decodes the energy-saving signal, and the indication information of the decoded energy-saving signal indicates that the terminal is not awakened, determining not to monitor the PDCCH;
and when the terminal fails to successfully decode or does not receive the energy-saving signal, determining not to monitor the PDCCH.
Furthermore, when the terminal feeds back the energy saving signal listening result to the network side device through the MAC CE signaling or the PUCCH, the energy saving signal listening result is indication information indicating whether the energy saving signal is successfully decoded, which includes three implementation manners, respectively:
the first method is as follows: after the energy-saving signal is successfully decoded, the terminal feeds back indication information indicating that the energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling or PUCCH, and if the energy-saving signal is unsuccessfully decoded, the feedback of the energy-saving signal interception result is not carried out;
the second method comprises the following steps: the terminal can feed back indication information indicating the decoding failure of the energy-saving signal to the network side equipment through MAC CE signaling or PUCCH after the decoding failure of the energy-saving signal, and does not feed back the interception result of the energy-saving signal if the decoding of the energy-saving signal is successful;
the third method comprises the following steps: after the terminal monitors the energy-saving signal, the terminal feeds back indication information indicating whether the received energy-saving signal is decoded successfully to the network side equipment through MAC CE signaling or PUCCH.
The above-described scheme will be exemplified below.
Firstly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling.
In a specific implementation process, the terminal may only feed back, after successfully decoding and receiving the energy-saving signal, indication information indicating that the energy-saving signal is successfully decoded to the network side device through MACCE signaling indication; or
The terminal feeds back indication information indicating the decoding failure of the energy-saving signal to the network side equipment through MAC CE signaling indication only after the decoding failure of the energy-saving signal; or
After the terminal monitors the energy-saving signal, the terminal feeds back indication information indicating whether the received energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling or PUCCH; or
After the terminal monitors the energy-saving signal, the terminal feeds back indication information indicating whether to monitor the PDCCH to the network side equipment through MAC CE signaling.
After successfully decoding the received energy-saving signal, the terminal feeds back indication information indicating that the energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling indication.
In specific implementation, referring to fig. 5, when a new MAC CE signaling is used to feed back an energy saving signal interception result to a network side device in fig. 5, a set of LCIDs (6 bits) is set for the MAC CE signaling, so that the MAC CE signaling is different from the existing MAC CE signaling, and the network side device may determine whether the MAC CE signaling is the MAC CE signaling used to feed back the energy saving signal interception result by identifying the LCIDs.
After the terminal successfully decodes the received energy-saving signal at the resource position where the network-side device is configured to listen to the energy-saving signal, the terminal sends the MAC CE signaling shown in fig. 5 to the network-side device;
and then, after receiving the MAC CE signaling fed back by the terminal, the network side equipment can determine which terminal successfully decodes the energy-saving signal according to the parameters carried in the MAC CE signaling.
Therefore, the network side equipment can calculate which terminals do not feed back the energy-saving signal interception result, and further know that the terminals which do not feed back the energy-saving signal interception result fail to intercept the energy-saving signal, so that the terminals can resend the energy-saving signal for the terminals which fail to decode the energy-saving signal, and thus the terminals can listen to the energy-saving signal again on the configured energy-saving signal retransmission resources.
And (II) after the terminal fails to decode the received energy-saving signal, the terminal feeds back indication information indicating the failure of decoding the energy-saving signal to the network side equipment through MAC CE signaling indication.
In specific implementation, referring to fig. 5, a feasible MAC CE format, when a MAC CE signaling is redefined in fig. 5 to be used for feeding back an energy saving signal interception result to a network side device, a group of LCIDs (6 bits) is set for the MAC CE signaling, so that the MAC CE signaling is different from the existing MAC CE signaling, and the network side device may determine whether the MAC CE signaling is the MAC CE signaling used for feeding back the energy saving signal interception result by identifying the LCIDs.
Wherein, when the terminal fails to successfully decode the received energy saving signal at the resource location of the monitoring energy saving signal configured by the network side device, the terminal sends the MAC CE signaling shown in fig. 5 to the network side device;
and then, after receiving the MAC CE signaling fed back by the terminal, the network side equipment can accurately determine which terminal energy-saving signal fails to be decoded according to the parameters carried in the MAC CE signaling.
In this way, the network side device may perform retransmission of the energy saving signal, and retransmit the energy saving signal to the terminal that fails to decode the energy saving signal, and then the terminal may listen to the energy saving signal again on the configured energy saving signal retransmission resource.
Compared with the scheme of feeding back the indication information indicating the successful decoding of the energy-saving signal to the network side equipment through the MAC CE signaling indication, the scheme has the advantage that the terminal energy consumption can be relatively reduced by feeding back the indication information indicating the decoding failure of the energy-saving signal to the network side equipment through the MAC CE signaling indication because the probability of the occurrence of the condition of the decoding failure of the energy-saving signal is relatively small.
And thirdly, after the terminal monitors the energy-saving signal, the terminal feeds back indication information indicating whether the received energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling or PUCCH.
In a specific implementation, the format of the MAC CE signaling in the present solution is consistent with the format of implementing a defined MAC CE signaling, and a specific implementation manner may refer to the description in the first embodiment, so that details are not repeated here.
When the bit before the LCID of the MAC CE signaling is used as the flag bit Ind indicating the power saving signal listening result, the flag bit may be set to take a different bit value to represent a different power saving signal listening result.
For example: when the terminal feeds back the energy-saving signal interception result to the network side equipment, the terminal can feed back whether the energy-saving signal is successfully decoded or not to the network side equipment;
assuming that a flag bit Ind indicating the energy-saving signal monitoring result in the MAC CE signaling is '1', indicating that the terminal successfully decodes the energy-saving signal;
when the flag bit Ind indicating the energy-saving signal interception result in the MAC CE signaling is "0", it indicates that the terminal has failed to decode the energy-saving signal;
thus, when the terminal needs to monitor the arrival of the time-frequency resource position of the energy-saving signal, if the terminal successfully decodes the energy-saving signal, the flag bit Ind in the MAC CE is valued as "1" and the MAC CE signaling is sent to the network side device;
and if the terminal fails to decode the energy-saving signal, the flag bit Ind in the MAC CE is set to be 0, and the MAC CE signaling is sent to the network side equipment.
And then, after receiving the MAC CE signaling fed back by the terminal, the network side equipment can accurately determine which terminal energy-saving signal fails to be decoded according to the parameters carried in the MAC CE signaling.
In this way, the network side device may perform retransmission of the energy saving signal, and retransmit the energy saving signal to the terminal that fails to decode the energy saving signal, and then the terminal may listen to the energy saving signal again on the configured energy saving signal retransmission resource.
And (IV) after the terminal monitors the energy-saving signal, feeding back indication information indicating whether to monitor the PDCCH to the network side equipment through MAC CE signaling.
In a specific implementation, the format of the MAC CE signaling in the present solution is consistent with the format of implementing a defined MAC CE signaling, and a specific implementation manner may refer to the description in the first embodiment, so that details are not repeated here.
When the bit before the LCID of the MAC CE signaling is used as the flag bit Ind indicating the power saving signal listening result, the flag bit may be set to take a different bit value to represent a different power saving signal listening result.
For example: when feeding back the energy-saving signal monitoring result to the network side equipment, the terminal can feed back whether to monitor the PDCCH to the network side equipment;
assuming that a flag bit Ind indicating the energy-saving signal monitoring result in the MAC CE signaling is '1', indicating that the terminal needs to monitor the PDCCH;
when the flag bit Ind indicating the energy-saving signal monitoring result in the MAC CE signaling is "0", it indicates that the terminal does not monitor the PDCCH;
thus, when the terminal needs to monitor the arrival of the time-frequency resource position of the energy-saving signal, if the terminal successfully decodes the energy-saving signal and determines that the indication information in the energy-saving signal indicates the terminal to monitor the PDCCH, the flag bit Ind in the MACCE is set to be 1, and the MAC CE signaling is sent to the network side equipment;
and if the terminal fails to successfully decode the energy-saving signal or determines that the indication information in the energy-saving signal indicates that the terminal does not monitor the PDCCH, dereferencing the flag bit Ind in the MAC CE to be 0 and sending the MAC CE signaling to the network side equipment.
And then, after receiving the MAC CE signaling fed back by the terminal, the network side equipment can accurately determine which terminal determines that the conclusion of performing the energy-saving operation determined by monitoring the energy-saving signal is opposite to the self-configured condition of performing the energy-saving operation according to the parameters carried in the MAC CE signaling.
In this way, when the energy-saving signal interception result is inconsistent with the energy-saving signal indication information configured by the network side device, the network side device may perform retransmission of the energy-saving signal, and retransmit the energy-saving signal to the terminal that fails in decoding the energy-saving signal, and then the terminal may listen to the energy-saving signal again on the configured energy-saving signal retransmission resource.
And secondly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the PUCCH.
In specific implementation, when feeding back the energy-saving signal listening result to the network-side device through the PUCCH, the terminal may feed back to the network-side device whether to decode the received energy-saving signal successfully, or may feed back to the network-side device whether to monitor the PDCCH.
The terminal may feed back, to the network side device, the indication information indicating whether the terminal successfully decodes the received energy-saving signal through the feedback signal in the HARQ feedback format via the PUCCH.
Further, the method for the terminal to feed back the energy-saving signal listening result to the network side device through the PUCCH includes the following three ways:
the first method is as follows: the terminal sends the indication information on a PUCCH pre-configured by the network side equipment;
the second method comprises the following steps: the terminal sends the indication information on a PUCCH spaced by K time slots or K symbols from the time domain resource position of the energy-saving signal;
wherein K is a positive integer and is notified by the network side device, or K is preconfigured, or K is determined according to SCS;
the third method comprises the following steps: and the terminal sends the indication information on a PUCCH with a set time interval away from the time domain resource position of the energy-saving signal.
It should be noted that, if the terminal feeds back the energy saving signal listening result to the network side device through the PUCCH, the indication information carries part or all of the following parameters:
cell ID and BWP ID of the Cell, number of energy-saving signal group corresponding to the terminal, and UE ID carried by the energy-saving signal.
After the terminal sends the HARQ feedback signal containing the energy-saving signal interception result to the network side equipment through the PUCCH, the network side equipment receives and decodes the HARQ feedback signal, and determines whether the terminal sending the HARQ feedback signal successfully decodes the received energy-saving signal according to the indication information obtained by decoding.
It should be noted that, in the foregoing embodiment, the number of times of transmission in the energy saving signal period in the energy saving signal resource configured by the network side device for the terminal is one.
In a specific implementation process, in order to improve the probability of the energy-saving signal received by the terminal, the network side device may configure to send the energy-saving signal for multiple times within the energy-saving signal period.
In specific implementation, the resources of the energy saving signal configured by the network side device include a time-frequency resource location of the terminal for intercepting the energy saving signal, a search space of the energy saving signal, an aggregation level of the energy saving signal, a transmission period of the energy saving signal, transmission times of the energy saving signal, and the like.
It should be noted that, when the network side device configures energy-saving signal resources for the terminal, the number of times of sending the energy-saving signal is greater than or equal to 2 times; thus, the network side device needs to configure corresponding resources for each energy saving signal in the energy saving signal transmission period.
Therefore, when the time-frequency resource position for monitoring the energy-saving signal arrives, the terminal wakes up and monitors the energy-saving signal at the time-frequency resource position, and determines whether to monitor the PDCCH according to whether the energy-saving signal sent by the network side equipment is successfully decoded, namely, receives the data sent by the network side equipment.
During specific implementation, when downlink data exists in network side equipment and needs to be sent to a terminal, the network side equipment sends an energy-saving signal to the terminal on a configured time-frequency resource for the terminal to monitor the energy-saving signal;
correspondingly, the terminal periodically wakes up and monitors the energy-saving signal on the time-frequency resource for monitoring the energy-saving signal, and when the terminal successfully decodes the received energy-saving signal and determines that the PDCCH needs to be monitored on the resource position of the PDCCH needing to be monitored in the DRX period according to the indication information in the successfully decoded energy-saving signal, the terminal receives data sent by the network side equipment;
when the terminal does not receive the energy-saving signal on the time-frequency resource for intercepting the energy-saving signal, or fails to decode the received energy-saving signal successfully, or determines that the PDCCH does not need to be intercepted according to the indication information in the energy-saving signal successfully decoded, it is determined that the energy-saving operation can be performed.
It should be noted that the energy saving operation referred to in this application includes: not monitoring PDCCH, not monitoring PDCCH at DRXon time, not running DRX on duration Timer.
Furthermore, the terminal monitors the energy-saving signal at the time-frequency resource position of the energy-saving signal configured by the network side equipment, and feeds back the energy-saving signal monitoring result to the network side equipment.
In specific implementation, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling; or the terminal can feed back the energy-saving signal listening result to the network side equipment through the PUCCH.
The description will be continued with respect to the two feedback manners, respectively.
Firstly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the MAC CE signaling.
In specific implementation, a new MAC CE signaling needs to be defined first, and the terminal feeds back the energy saving signal interception result to the network side device through the newly defined MA C CE signaling.
Further, when feeding back the energy saving signal interception result to the network side device, the terminal may feed back whether to successfully decode the energy saving signal to the network side device, and may also feed back whether to monitor the PDCCH determined according to the energy saving signal to the network side device.
It should be noted that the format of the MAC CE signaling is the same as that in the foregoing embodiment, and therefore, the description is omitted.
In specific implementation, the network side device determines the energy saving signal feedback result fed back by the terminal according to the value of the flag bit Ind indicating the energy saving signal interception result in the MAC CE signaling.
Correspondingly, the terminal sends a feedback signal to the network side equipment every time the terminal listens for the energy-saving signal.
When the network side device repeatedly sends the energy-saving signal for multiple times, in order to reduce the energy loss of the terminal, the terminal can not listen to the subsequent energy-saving signal after successfully decoding the received energy-saving signal.
The following description will be made in conjunction with examples.
(1) After the terminal successfully decodes the received energy-saving signal, the terminal feeds back indication information indicating that the energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling indication.
In specific implementation, referring to fig. 5, when a new MAC CE signaling is used to feed back an energy saving signal interception result to a network side device in fig. 5, a set of LCIDs (6 bits) is set for the MAC CE signaling, so that the MAC CE signaling is different from the existing MAC CE signaling, and the network side device may determine whether the MAC CE signaling is the MAC CE signaling used to feed back the energy saving signal interception result by identifying the LCIDs.
After the terminal successfully receives and decodes the energy-saving signal at the time-frequency resource position of the monitoring energy-saving signal configured by the network side equipment, the terminal sends the MAC CE signaling shown in the figure 5 to the network side equipment; if the terminal fails to decode the energy-saving signal successfully at the resource position of the energy-saving signal intercepted and configured by the network side equipment, the terminal does not feed back the energy-saving signal interception result to the network side equipment and intercepts the energy-saving signal on the time-frequency resource of the next energy-saving signal intercepted;
after the terminal determines that the energy-saving signal cannot be successfully decoded, the terminal also records the number of time domain resource positions of the intercepted energy-saving signal in a period when the energy-saving signal is intercepted, and judges whether the number of the time domain resource positions of the intercepted energy-saving signal is smaller than the number of times of sending in the configured energy-saving signal period, if so, the terminal continues to intercept the energy-saving signal in the time frequency resource position of the next energy-saving signal, and if not, the decoding of all the energy-saving signals in the current period fails.
Correspondingly, after receiving the MAC CE signaling fed back by the terminal for many times, the network side device can determine whether the terminal successfully decodes the energy-saving signal according to the parameters carried in the MAC CE signaling.
Therefore, when the network side equipment determines that all the energy-saving signals in the current period fail to be decoded, the network side equipment executes retransmission of the energy-saving signals, and retransmits the energy-saving signals to the terminal with the failed decoding of the energy-saving signals, so that the terminal can listen to the energy-saving signals again on the configured energy-saving signal retransmission resources.
(1) After the terminal successfully decodes the received energy-saving signal, the terminal feeds back indication information indicating that the energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling indication.
In specific implementation, referring to fig. 5, when a new MAC CE signaling is used to feed back an energy saving signal interception result to a network side device in fig. 5, a set of LCIDs (6 bits) is set for the MAC CE signaling, so that the MAC CE signaling is different from the existing MAC CE signaling, and the network side device may determine whether the MAC CE signaling is the MAC CE signaling used to feed back the energy saving signal interception result by identifying the LCIDs.
After the terminal fails to successfully decode the received energy-saving signal at the resource position where the network-side device is configured to listen to the energy-saving signal, the terminal sends an MAC CE signaling shown in fig. 5 to the network-side device, and then listens to a subsequent energy-saving signal; after the terminal successfully decodes the received energy-saving signal at the resource position of the energy-saving signal intercepted and configured by the network side equipment, the terminal does not intercept the subsequent energy-saving signal;
correspondingly, after receiving the MAC CE signaling fed back by the terminal, the network side equipment can determine which terminal energy-saving signal fails to be decoded according to the parameters carried in the MAC CE signaling;
when the number of times that the network side equipment receives the MAC CE signaling fed back by the terminal is equal to the number of times that the network side equipment transmits the energy-saving signal in a configured period, determining that the decoding of the terminal energy-saving signal corresponding to the MAC CE signaling fails; and then the network side equipment executes retransmission of the energy-saving signal, and retransmits the energy-saving signal to the terminal with the decoding failure of the energy-saving signal, so that the terminal can listen to the energy-saving signal again on the configured energy-saving signal retransmission resource.
Compared with the scheme of feeding back the indication information indicating the successful decoding of the energy-saving signal to the network side equipment through the MAC CE signaling indication, the scheme has the advantage that the terminal energy consumption can be relatively reduced by feeding back the indication information indicating the decoding failure of the energy-saving signal to the network side equipment through the MAC CE signaling indication because the probability of the occurrence of the condition of the decoding failure of the energy-saving signal is relatively small.
And thirdly, after the terminal monitors the energy-saving signal, the terminal feeds back indication information indicating whether the energy-saving signal is successfully decoded to the network side equipment through MAC CE signaling or PUCCH.
In a specific implementation, the format of the MAC CE signaling in the present solution is consistent with the format of implementing a defined MAC CE signaling, and a specific implementation manner may refer to the description in the first embodiment, so that details are not repeated here.
When the bit before the LCID of the MAC CE signaling is used as the flag bit Ind indicating the power saving signal listening result, the flag bit may be set to take a different bit value to represent a different power saving signal listening result.
In specific implementation, the implementation of the scheme is the same as the way when the terminal feeds back the indication information indicating whether the received energy saving signal is successfully decoded to the network side device through the MAC CE signaling or the PUCCH after monitoring the energy saving signal, so that the detailed description is omitted.
And (IV) after the terminal monitors the energy-saving signal, feeding back indication information indicating whether to monitor the PDCCH to the network side equipment through MAC CE signaling.
In a specific implementation, the format of the MAC CE signaling in the present solution is consistent with the format of implementing a defined MAC CE signaling, and a specific implementation manner may refer to the description in the first embodiment, so that details are not repeated here.
When the bit before the LCID of the MAC CE signaling is used as the flag bit Ind indicating the power saving signal listening result, the flag bit may be set to take a different bit value to represent a different power saving signal listening result.
In specific implementation, the implementation of the scheme is the same as the way when the terminal feeds back the indication information indicating whether the received energy saving signal is successfully decoded to the network side device through the MAC CE signaling or the PUCCH after monitoring the energy saving signal, so that the detailed description is omitted.
And secondly, the terminal can feed back the energy-saving signal interception result to the network side equipment through the PUCCH.
In specific implementation, when feeding back the energy-saving signal monitoring result to the network side device through the PUCCH, the terminal may feed back whether to successfully decode the energy-saving signal to the network side device, and may also feed back whether to monitor the PDCCH to the network side device.
The terminal may feed back, to the network side device, the indication information indicating that the terminal successfully decodes the received energy saving signal through the feedback signal in the HARQ feedback format via the PUCCH.
Further, the method for the terminal to feed back the energy-saving signal listening result to the network side device through the PUCCH includes the following three ways:
the first method is as follows: the terminal sends the indication information on a PUCCH pre-configured by the network side equipment;
the second method comprises the following steps: the terminal sends the indication information on a PUCCH spaced by K time slots or K symbols from the time domain resource position of the energy-saving signal;
wherein K is a positive integer and is notified by the network side device, or K is preconfigured, or K is determined according to SCS;
the third method comprises the following steps: and the terminal sends the indication information on a PUCCH with a set time interval away from the time domain resource position of the energy-saving signal.
It should be noted that, if the terminal feeds back the energy saving signal listening result to the network side device through the PUCCH, the indication information carries part or all of the following parameters:
cell ID and BWP ID of the Cell, number of energy-saving signal group corresponding to the terminal, and UE ID carried by the energy-saving signal.
After the terminal sends the HARQ feedback signal contained in the energy-saving signal interception result to the network side equipment through the PUCCH, the network side equipment receives and decodes the HARQ feedback signal, and determines whether the terminal sending the HARQ feedback signal successfully receives the energy-saving signal according to the indication information obtained by decoding.
After the terminal monitors the energy-saving signal at the resource position of the energy-saving signal monitored by the network side equipment, if the energy-saving signal is successfully decoded, the terminal sends an HARQ feedback signal to the network side equipment and does not monitor the subsequent energy-saving signal any more;
if the energy-saving signal is determined to be unsuccessfully decoded, sending an HARQ feedback signal to the network side equipment, and continuously monitoring a subsequent energy-saving signal;
and after the terminal determines that the energy-saving signal cannot be successfully decoded, the terminal also records the number of time domain resource positions of the intercepted energy-saving signal in a period when the energy-saving signal is intercepted, and judges whether the number of the time domain resource positions of the intercepted energy-saving signal is smaller than the number of times of transmission in the configured energy-saving signal period, if so, the terminal continues to intercept the energy-saving signal in the time frequency resource position of the next energy-saving signal, and if not, the decoding of all the energy-saving signals in the current period fails.
Correspondingly, after receiving the HARQ feedback signal fed back by the terminal for multiple times, the network side device may determine whether the terminal successfully decodes the energy-saving signal according to the parameters carried in the HARQ feedback signal.
Therefore, when the network side equipment determines that all the energy-saving signals in the current period fail to be decoded, the network side equipment executes retransmission of the energy-saving signals, and retransmits the energy-saving signals to the terminal with the failed decoding of the energy-saving signals, so that the terminal can listen to the energy-saving signals again on the configured energy-saving signal retransmission resources.
Furthermore, when the network where the terminal is located is extremely unstable, the terminal may not receive the energy-saving signal sent by the network-side device for a certain period of time, which may cause the terminal to lose a large amount of downlink data sent by the network-side device.
In order to solve the problem, in the application, a maximum threshold of decoding failure of the energy-saving signal is configured in advance in the network side device, and when the decoding failure times of the terminal reach the maximum threshold of the failure, the energy-saving signal resource is configured for the terminal again.
In a specific implementation, if the number of times of successfully decoding the energy-saving signal reaches N times, the terminal sends, to the network side device through an RRC signaling, indication information for indicating that the energy-saving signal has failed to be decoded N times.
Correspondingly, after receiving the indication information which is fed back by the terminal through the RRC signaling and used for indicating that the decoding of the energy-saving signal fails for N times, the network side equipment reconfigures the resource for intercepting the energy-saving signal for the terminal.
Therefore, the network side equipment can re-configure the energy-saving signal resource for the terminal when the network where the terminal is located is extremely unstable, and the terminal is prevented from losing a large amount of data.
It should be noted that, by configuring the maximum threshold of the decoding failure of the energy saving signal in advance, and when the number of decoding failure times of the terminal reaches the maximum threshold of the failure, configuring the energy saving signal resource for the terminal again can be used alone, so as to improve the stability of data transmission between the terminal and the network side device.
In the embodiment of the invention, the energy-saving signal interception result is fed back to the network side equipment, and the probability of receiving the energy-saving signal by the terminal can be improved by increasing the energy-saving signal sending times, so that the possibility of data loss of the terminal is reduced.
As shown in fig. 6, an embodiment of the present invention further provides a method for listening to a power saving signal, where the method includes:
step 600, the terminal monitors energy-saving signals at a pre-configured time-frequency resource position;
601, if the energy-saving signal is not successfully decoded, the terminal continues to monitor the PDCCH on continuous N PDCCH opportunities after the moment when the energy-saving signal is received;
step 602, if the PDCCH of the terminal is not detected on the N PDCCH opportunities, the terminal performs an energy saving operation;
the PDCCH opportunity is a PDCCH resource which can be used in a time slot within a discontinuous reception duration.
Wherein N is a positive integer; and the N is notified by the network side equipment or the N is configured in advance.
In specific implementation, the terminal listens to the energy saving signal at a pre-configured time-frequency resource position, and if the energy saving signal is sent for multiple times within a pre-configured period, the terminal stops listening to the subsequent energy saving signal after receiving the energy saving signal or successfully decoding the energy saving signal.
The following examples are given.
For example:
in specific implementation, the network side device sends an energy-saving signal to the terminal at a pre-configured resource location, and then the UE periodically detects the resource location of the energy-saving signal. If the energy-saving signal is detected and successfully decoded, the UE performs PDCCH interception, otherwise, the UE performs energy-saving operation.
Wherein, the terminal performs energy-saving operation including: not monitoring PDCCH, not monitoring PDCCH at DRX on time, not running DRX on duration Timer.
When the terminal listens for the energy-saving signal, the network side device is first required to configure a resource for listening for the energy-saving signal for the terminal, wherein the energy-saving signal indicates whether the terminal performs energy-saving operation.
Specifically, the configuring, by the network side device, the resource for intercepting the energy-saving signal for the terminal includes:
and monitoring the time-frequency resource position of the energy-saving signal, the search space of the energy-saving signal, the aggregation level of the energy-saving signal, the transmission period of the energy-saving signal and the transmission times of the energy-saving signal.
The time-frequency resource position of the energy-saving signal is the time-frequency resource position of the energy-saving signal which needs to be monitored by the terminal;
the search space of the energy-saving signal refers to a resource position of a PDCCH for detecting the energy-saving signal or an alternative resource format of the PDCCH for detecting the energy-saving signal;
the aggregation level of the power saving signals refers to the number of continuous CEEs occupied by the power saving signals;
the sending period of the energy-saving signal refers to the period duration of the energy-saving signal sent by the network side equipment;
the sending times of the energy-saving signals are the sending times of the energy-saving signals in a period configured by the network side equipment.
And then, the network side equipment sends an energy-saving signal to the terminal when the terminal needs to be awakened for PDCCH interception.
And then, the terminal monitors the energy-saving signal at the time-frequency resource position of the energy-saving signal configured by the network side equipment.
After receiving an energy-saving signal sent by network side equipment, a terminal monitors a PDCCH (physical downlink control channel); if the terminal fails to decode the energy-saving signal, the terminal continues to monitor the PDCCH on continuous N PDCCH opportunities after the moment of receiving the energy-saving signal; the PDCCH opportunity is a PDCCH resource which can be used in a time slot within a discontinuous reception duration.
When the terminal continues to monitor the PDCCH on the set continuous N PDCCH opportunities, if the terminal really hears the PDCCH corresponding to the terminal, the terminal continuously monitors the subsequent PDCCH;
if the terminal does not monitor the PDCCH of the terminal on the N PDCCH opportunities, the terminal performs energy-saving operation;
wherein N is a positive integer; and the N is notified by the network side equipment or the N is configured in advance.
Another example is:
in specific implementation, the network side device sends an energy-saving signal to the terminal at a pre-configured resource location, and then the UE periodically detects the resource location of the energy-saving signal. If the energy-saving signal is detected and successfully decoded, the UE performs PDCCH interception, otherwise, the UE performs energy-saving operation.
Wherein, the terminal performs energy-saving operation including: the terminal does not monitor the PDCCH, does not monitor the PDCCH at the DRX on time, and does not run the DRX on duration Timer.
When the terminal listens for the energy-saving signal, the network side device is first required to configure a resource for listening for the energy-saving signal for the terminal, wherein the energy-saving signal indicates whether the terminal performs energy-saving operation.
Specifically, the configuring, by the network side device, the resource for intercepting the energy-saving signal for the terminal includes:
and monitoring the time-frequency resource position of the energy-saving signal, the search space of the energy-saving signal, the aggregation level of the energy-saving signal, the transmission period of the energy-saving signal and the transmission times of the energy-saving signal.
The time-frequency resource position of the energy-saving signal is the time-frequency resource position of the energy-saving signal which needs to be monitored by the terminal;
the search space of the energy-saving signal refers to a resource position of a PDCCH for detecting the energy-saving signal or an alternative resource format of the PDCCH for detecting the energy-saving signal;
the aggregation level of the power saving signals refers to the number of continuous CEEs occupied by the power saving signals;
the sending period of the energy-saving signal refers to the period duration of the energy-saving signal sent by the network side equipment;
the sending times of the energy-saving signals are the sending times of the energy-saving signals in a period configured by the network side equipment.
When the network side device is set to transmit the energy-saving signal for a plurality of times (for example, 5 times) in the energy-saving signal period. When the network side equipment needs to send downlink data to the terminal, the network side equipment sequentially and continuously sends 5 the energy-saving signal to the terminal;
subsequently, the terminal monitors the energy-saving signal at the time-frequency resource position of the energy-saving signal configured by the network side equipment;
if the terminal successfully decodes the received energy-saving signal, the terminal monitors the PDCCH and does not monitor a subsequent energy-saving signal any more;
if the terminal fails to decode the received energy-saving signal successfully, the terminal continues to monitor the subsequent energy-saving signal at the time-frequency resource position configured by the network side equipment for monitoring the energy-saving signal, and the terminal records the number of time-domain resource positions for monitoring the energy-saving signal in the period;
the terminal judges whether the number of the time domain resource positions of the intercepted energy-saving signals in the period is smaller than the energy-saving signal sending times in the network side equipment setting period, and if so, the terminal continues intercepting the subsequent energy-saving signals;
if not, the terminal determines that the decoding of the current energy-saving signal fails, and the terminal continues to monitor the PDCCH on continuous N PDCCH opportunities after the last moment of receiving the energy-saving signal; the PDCCH opportunity is a PDCCH resource which can be used in a time slot within the discontinuous reception duration.
When the terminal continues to monitor the PDCCH on the set continuous N PDCCH opportunities, if the terminal really hears the PDCCH corresponding to the terminal, the terminal continuously monitors the subsequent PDCCH;
if the terminal does not monitor the PDCCH of the terminal on the N PDCCH opportunities, the terminal performs energy-saving operation; wherein N is a positive integer;
