As shown in fig. 2, an embodiment of the present application provides an information processing method, which is executed by a first terminal, and includes:
step 201: acquiring first configuration information and second configuration information, wherein the first configuration information is sidelink Discontinuous Reception (DRX) configuration information, and the second configuration information comprises at least one of sidelink reference signal measurement configuration information and Channel Busy Ratio (CBR) measurement configuration information.
In this step, the first terminal acquires the first configuration information from the base station or the second terminal, and acquires the second configuration information from the base station or the second terminal.
It should be noted that the obtaining of the first configuration information and the second configuration information does not have a necessary sequence, may occur simultaneously, or may have a sequence, and the first configuration information and the second configuration information may be carried in the same message or may be carried in two different messages.
In the embodiment of the present application, CBR is one parameter for congestion control in Sidelink. Each time, a User Equipment (UE) in mode 2 measures a CBR value, And for different transmission resource pools, the UE dynamically adjusts its transmission parameters, such as maximum transmission power, retransmission times, Modulation And Coding Scheme (MCS), according to the result of measuring the CBR. Here, the mode 2 is a mode in which the terminal autonomously selects resources.
It should be noted that, in the embodiment of the present application, only CBR is used for illustration, and other measurement quantities for measuring whether a channel is busy may be applied to the embodiment of the present application, for example, an Acknowledgement (ACK) rate, a Negative Acknowledgement (NACK) rate, a retransmission rate, and the like.
The purpose of DRX is for power saving, and a terminal in a DRX state does not need to continuously monitor a control channel. But if the terminal does not listen to the control channel for a long time, the delay of data transmission will be increased once data arrives. In order to take power saving and transmission delay into account, according to the time length of the terminal monitoring the channel, Media Access Control (MAC) supports two DRX cycles, a DRX long cycle and a DRX short cycle. If the data volume of the terminal is predicted to be more frequent or the service is sensitive to time delay, the network can configure the terminal to use a DRX short cycle; if the data volume of the predicted terminal is sparse and the time delay is insensitive, the network can configure the terminal to only use the DRX long cycle. In order to facilitate the terminal to switch between the DRX long cycle and the DRX short cycle, the DRX long cycle is required to be an integral multiple of the DRX short cycle, so as to ensure that the on Duration (on Duration) of the DRX long cycle and the DRX short cycle are aligned.
In order to support the DRX mechanism, the base station configures a DRX related timer and parameters for the terminal, which specifically include:
drx-LongCycleStartOffset: a cycle and offset for configuring a long DRX cycle, the unit of the cycle and offset being milliseconds;
drx-short cycle: a period and an offset for configuring the short DRX period, the unit of the period and the offset being milliseconds;
drx-ShortCycleTimer: the unit of the time length used for controlling the terminal to use the short DRX period is an integer, and the time length indicates that the terminal needs to maintain the integral multiple of short periods once entering the short DRX period;
drx-onDurationTimer: the DRX continuously monitors a timer during which the terminal needs to continuously monitor a PDCCH control channel of the network. The timer unit is milliseconds;
drx-slotofset: the terminal starts the time delay of DRX onDurationTimer, and sets the offset of the starting time of DRX onDuration relative to the starting point of the subframe through the parameter, wherein the offset is integral multiple of 1/32 milliseconds;
drx-inactivytytimer: the DRX inactivity timer. The timer is started when the terminal receives the first symbol after the PDCCH signaling is scheduled aiming at uplink/downlink new data, during the running period of the timer, the terminal needs to continuously monitor a control channel, and the unit of the timer is millisecond;
drx-HARQ-RTT-TimerDL: and the downlink HARQ RTT timer is maintained on the basis of each downlink process, and the length of the timer is the minimum time interval from the HARQ feedback time to the HARQ retransmission aiming at the process. The terminal will start the timer at the first symbol after the HARQ NACK feedback of the process only if the data corresponding to the downlink process is not decoded successfully. If the current terminal only runs drx-HARQ-RTT-TimeDL and/or drx-HARQ-RTT-TimerUL, the terminal does not need to monitor a PDCCH control channel, and the unit of the timer is a symbol;
drx-HARQ-RTT-timerll: and the uplink HARQ RTT timer is maintained on the basis of each uplink process, and the length of the timer is the minimum time interval from the PUSCH transmission time to the HARQ retransmission aiming at the process. After uplink PUSCH transmission, the terminal starts an uplink HARQ RTT timer aiming at the uplink process, if PUSCH transmission uses PUSCH repetition (PUSCH repeption), the uplink HARQ RTT timer is started after the PUSCH is repeated for the first time so as to ensure that the PUSCH retransmission can be stopped in time after the PUSCH is analyzed by the base station in advance. The timer unit is a symbol;
drx-retransmission timerdl: and starting the timer by the next symbol after the expiration of the downlink retransmission timer, drx-HARQ-RTT-TimerDL. During the running of the timer, the terminal monitors a control channel of the network, and stops the timer if downlink scheduling information or a downlink configuration grant (configured grant) for the process is received. The timer unit is a time slot (slot);
drx-retransmission timerll: and starting the timer by the next symbol after the expiration of the uplink retransmission timer, drx-HARQ-RTT-TimerUL. During the running of the timer, the terminal monitors a control channel of the network, and stops running if uplink scheduling information or an uplink configured grant for the process is received. The timer unit is a slot (time slot).
The parameters form a set of DRX configuration, and the terminal carries out corresponding discontinuous receiving operation according to the configuration.
Optionally, the secondary link reference signal measurement configuration information includes at least one of:

Here, after the sidelink DRX is configured, the terminal may not perform reference signal measurement or perform related reference signal measurement on a specific channel or a specific message during a sidelink DRX inactivity time.
Optionally, the sidelink discontinuous reception DRX configuration information is used to indicate a sidelink DRX configuration of the first terminal and/or the second terminal, or the sidelink discontinuous reception DRX configuration information includes at least one of the sidelink DRX configuration information of the first terminal and the sidelink DRX configuration information of the second terminal;
wherein the second terminal is a terminal communicating with the first terminal.
In this embodiment, the secondary link DRX configuration information may be used to indicate the secondary link DRX configurations of the first terminal and the second terminal at the same time, or may only indicate the secondary link DRX configuration of the first terminal, or only indicate the secondary link DRX configuration of the second terminal.
That is to say, in this embodiment of the present application, the sidelink DRX configurations of the first terminal and the second terminal may be independent from each other, or may be a mutually matched sidelink DRX configuration obtained after at least two of the first terminal, the second terminal, and the base station negotiate, that is, the first terminal performs data transmission when the sidelink DRX of the second terminal is active time, and the second terminal performs data transmission when the sidelink DRX of the first terminal is active time.
Optionally, the second operation comprises at least one of:
performing a CBR measurement at a first time instant according to a first CBR window, the first CBR window comprising X time units located before the first time instant;
in the case that the first CBR window includes the inactivity time of the sidelink DRX, determining a first value, where the first value is a value used for CBR measurement in the inactivity time, where the first value may be a default value, optionally, the first value represents a proportion of subchannels in which the measured RSSI exceeds a threshold, or the first value represents the RSSI, or the first value represents a number of subchannels in which the measured RSSI exceeds the threshold. For example, a default value is selected to represent RSSI, the default value may be 0 or non-0, and the default value may be implemented by protocol convention or second terminal configuration or base station configuration;

and under the condition that the second time is not within the activation time of the secondary link DRX of the second terminal, performing CBR measurement at a third time, wherein the third time is before the activation time of the secondary link DRX of the second terminal, and the time for sending data and/or signaling to the second terminal after the CBR measurement is completed at the third time is within the activation time of the secondary link DRX of the second terminal.
It should be noted that the time unit in the embodiment of the present application may be a time slot, a subframe, a half subframe, or the like.
Optionally, the value of Y is determined by at least one of:
the value of X, for example, is a multiple of X, or X plus some value;
a period of active time of a secondary link DRX configuration;
the size of the parameter value of the sidelink DRX configuration, such as at least one of the parameters DRX-onduration timer, DRX-inactivity timer, DRX-retransmission timer, etc.
Optionally, the value of N1 and/or N2 is determined by at least one of:
the activation time of the secondary link DRX before the first moment; for example, there are Z slots in which the first terminal is active time before the first time, then N1 equals Z, N2 equals X-Z or equals Y-Z slots. For another example, if Z timeslots of the first terminal are in the active time before the first time, then N1 is equal to Z, N2 is equal to M, that is, X-Z timeslots are included in M slots located after the first time, so that the first terminal is in the active time of the sidelink discontinuous reception, where X is the number of timeslots in the configured CBR window.
A period of active time of a secondary link DRX configuration;
size of parameter value of secondary link DRX configuration.
For example, when the first terminal calculates CBR at time N, the calculation is performed based on a CBR window, where the CBR window is X slots before time N, and if the first terminal is configured with the secondary link DRX, the processing is performed according to at least one of the following:
calculating according to X time slots before the N moment without adjusting the CBR window;
the CBR window is not adjusted, but if the CBR window includes the sidelink DRX inactivity time of the first terminal, then a default value is taken for the measurement result in the inactivity time to represent the measured RSSI;
adjusting a CBR window, and if the result of X slots is needed, taking X slots in the activation time before the N moment as the calculation result of the CBR;
adjusting a CBR window, if X slot results are needed and the original CBR window contains the minor link DRX inactive time of the first terminal, adjusting the calculation of the CBR to the result needing Y slots, wherein the value of Y or the calculation method of Y is configured by a protocol convention, a base station or a second terminal;
the CBR window is adjusted, and at this time, the time slot before the N time is no longer limited, and the time slot after the N time may also be counted into the CBR window.
For another example, the first terminal performs CBR measurement before sending data and/or signaling to the second terminal, and may specifically perform processing according to at least one of the following:
if the data and/or signaling sending time after the CBR measurement is not in the secondary link DRX activation time of the second terminal, the first terminal does not carry out the CBR measurement;
and delaying the time point of the CBR measurement to the front of the activation time of the second terminal so that the first terminal can transmit to the second terminal after the CBR measurement is carried out and the second terminal can be ensured to receive within the secondary link DRX activation time.
Here, after the sidelink DRX is configured, when the terminal measures the CBR, the terminal may adjust the calculation of the CBR in various ways if the CBR window includes the sidelink DRX inactivity time, or may postpone a time point of the CBR measurement when the terminal is not aligned with the sidelink DRX inactivity time of the opposite terminal.
According to the information processing method, when the terminal is configured with the secondary link DRX, the RSRP or the resource pool CBR can be correctly measured, and the related measurement result can be adjusted based on whether the terminal is in the secondary link non-activation time, so that the terminal can correctly obtain the measurement result, and then power control or sending resource selection and the like can be carried out according to the measurement result.
