Description

Method and apparatus for signal processing
Technical Field
The present application relates to the field of communications, and in particular, to a method and an apparatus for signal processing.
Background
In a conventional data transmission scheme, in consideration of burstiness of data packet transmission (for example, there is data transmission in a period of time, and there may be no data transmission in the next period of time), in order to avoid that power consumption overhead is large due to a Physical Downlink Control Channel (PDCCH) being monitored all the time, a concept of Discontinuous Reception (DRX) is introduced. The terminal monitors the PDCCH only in each downlink subframe within an on duration (duration) in each DRX period, and does not monitor the PDCCH during a sleep period in the DRX period, so as to reduce power consumption.
In addition, the network device may configure a time slice for the terminal, for example, in order to support inter-frequency and inter-system measurement, the time slice is a measurement GAP (GAP), and data transmission and reception processing is not performed in the measurement GAP.
When the time slice overlaps with the timer, the timer may be overtime due to the existence of the time slice, and further, the signal transmission delay is long. For example, in the case that the timer is an on duration timer, when there is an overlap between the time slice and the on duration timer, the on duration timer may expire due to the time slice, so that the terminal enters a DRX sleep period and needs to wait for a next DRX cycle to transmit or receive data, thereby causing a delay in data transmission and reception.
Disclosure of Invention
The application provides a method and a device for processing signals, which can reduce the receiving and transmitting delay of data.
In a first aspect, a method of signal processing is provided, the method including:
when the time slice overlaps with the time slice during the timing period of the timer, stopping or restarting the timing of the timer, wherein the time slice is a time period when the first terminal and the first network equipment do not perform data transceiving;
and when the timer expires, performing signal processing corresponding to the timer.
When the first terminal detects that the time period of the timer overlaps with the time slice in time, the first terminal stops the timing of the timer, and can restart the timer to continue timing when the end of the time slice is detected, so that the overtime of the timer caused by the fact that the timer still times in the time slice can be avoided, and the signal transmission delay is longer; or when the first terminal detects that the time period of the timer overlaps with the time slice in time, the first terminal can restart the timer to start timing, so that the signal transmission delay caused by the time slice can be reduced. That is to say, the embodiment of the application can reduce the transmission delay of the signal, and further improve the reliability of data transmission.
In some possible implementations, the method further includes: when the time slice is detected during the timer count period, it is determined that the timer count period overlaps with the time slice.
The first terminal may encounter the time slice during the timer counting, and the first terminal may restart the timer or stop the timer counting, thereby avoiding being influenced by the time slice.
In some possible implementations, the method further includes: the detection by the first terminal of an overlap of a time slice during the timer timing may be a detection of a start of the timer by the timer during a time slice run.
The first terminal runs into the timer for timing after the time slice is set, and the first terminal can stop the timing of the timer, namely, the timer is not started, and the timer is started again after the time slice is finished.
In some possible implementations, the timer is any one of a discontinuous reception activity timer, a discontinuous reception deactivation timer, a discontinuous reception retransmission timer, a discontinuous reception loopback time timer, a secondary cell deactivation timer, or a bandwidth partial deactivation timer.
The DRX-duration timer generally starts timing at the beginning of each DRX cycle, during which the first terminal may keep monitoring the PDCCH sent by the first network device, and stops monitoring the PDCCH at the end of the DRX-duration timer, thereby saving power consumption for the first terminal.
The DRX-inactive timer is started after a terminal successfully decodes a PDCCH indicating initially transmitted uplink or downlink data, and counts the number of subframes of the continuous PDCCH which is continuously in an activated state during the timing period of the DRX-inactive timer. That is, the DRX-inactive timer is restarted once when the first terminal has the initial data to be transmitted scheduled.
When the DRX-HARQ-RTT-timer fails to decode a Transport Block (TB) of a downlink HARQ process (process), the terminal may assume that there is a retransmission at least after the "HARQ RTT" subframe, and therefore the terminal does not need to monitor the PDCCH during the DRX-HARQ-RTT-timer.
The terminal may start a DRX-retransmission timer for the HARQ process when the DRX-retransmission timer expires and the corresponding HARQ process received data is not successfully decoded, and may monitor a PDCCH for HARQ retransmission during the DRX-retransmission timer.
In the duplication transmission of carrier aggregation, two links of a primary cell (pcell) and a secondary cell (scell) transmit the same data packet, a first terminal can control the deactivation of the secondary cell through a scell-deactivation timer, after the scell-deactivation timer starts timing, if the overlap of the scell-deactivation timer and a time slice is detected, the first terminal restarts the scell-deactivation timer, and the secondary cell is deactivated until the timing is overtime; or the first terminal stops the cell-deactivation timer, continues timing of the cell-deactivation timer after the time slicing is finished, and deactivates the auxiliary cell until the timing is overtime. That is to say, in the embodiment of the present application, the first terminal reduces the influence on data transmission caused by that the first terminal cannot receive the PDU or the PDCCH and still performs timing of the cell-deactivation timer under the condition of overlapping with the time slicing. For example, the situation that the secondary cell is overtime and then deactivated due to the overlapping of the scell-deactivation timer and the time slice in the link of the secondary cell is avoided, that is, only the link of the primary cell is left to be transmitted, so that the reliability of data transmission is reduced is avoided.
The bandwidth part may include an initial BWP, a default BWP, and an active BWP, and the network device may schedule the terminal to transmit on different BWPs according to the data volume transmission requirements of the service. In addition, the terminal may control the switching of the BWP by setting a BWP inactive timer, specifically, if the terminal has no data transmission or data scheduling for a long time on a certain activated BWP, the terminal may switch to the initial BWP or default BWP after the BWP inactive timer expires, thereby reducing the power consumption of the terminal; if the terminal has data to send, it does not want BWP inactive timer overtime, namely, it does not switch BWP. Therefore, when the timing process of the BWP inactive timer overlaps with the time slicing, the embodiment of the present application may reduce the timeout of the BWP inactive timer caused by the time slicing by stopping or restarting the BWP inactive timer, thereby improving the data transmission performance.
In some possible implementations, where the timer is any one of a discontinuous reception active timer, a discontinuous reception deactivation timer, a discontinuous reception retransmission timer, or a discontinuous reception loopback time timer, the time slicing includes at least one of almost blank subframes, multicast broadcast single frequency network subframes, flexible symbols, or measurement gaps.
The network device generally configures ABS subframes, MBSFN subframes, flexible symbols, etc. for the terminal, so that services such as macro-micro networking, multi-hop, or vehicle networking (V2X) can be supported. The dedicated PDCCH and PDSCH of the terminal are not sent on the ABS subframe, and only some necessary public signals can be sent, so that the interference to the adjacent cell can be avoided. The MBSFN subframe is mainly used for transmitting the multicast broadcast MBMS service, and the PDSCH is not transmitted on the MBSFN subframe, so that the interference among cells can be eliminated.
In some possible implementations, where the timer deactivates the timer for the secondary cell, or the bandwidth portion deactivates the timer, the time-slicing includes at least one of almost blank subframes, multicast broadcast single frequency network subframes, flexible symbols, measurement gaps, or discontinuous reception sleep periods.
The network device generally configures ABS subframes, MBSFN subframes, flexible symbols, etc. for the terminal, so as to support services such as macro-micro networking, multi-hop, or car networking. And not monitoring the PDCCH in the dormant period of the DRX period so as to reduce the power consumption of the terminal. The dedicated PDCCH and PDSCH of the terminal are not sent on the ABS subframe, and only some necessary public signals can be sent, so that the interference to the adjacent cell can be avoided. The MBSFN subframe is mainly used for transmitting the multicast broadcast MBMS service, and the PDSCH is not transmitted on the MBSFN subframe, so that the interference among cells can be eliminated.
In some possible implementations, the time-slicing is used for data transceiving of the second terminal with the second network device, and/or the time-slicing is used for data transceiving of the second terminal with the third terminal.
The time slice is not used for data transceiving between the first terminal and the first network device, but the time slice can be used for data transceiving between other terminals or between the terminal and the network device, so that the resource utilization rate is improved.
In some possible implementations, the performing, when the timer expires, signal processing corresponding to the timer includes:
stopping transmitting and receiving data with the first network equipment when the timer expires;
or when the timer expires, switching the bandwidth part;
or when the timer expires, deactivating the secondary cell.
When the timer expires, the terminal may perform signal processing corresponding to the timer.
In a second aspect, a method of signal processing is provided, the method comprising:
transmitting a Scheduling Request (SR) during the timing of a deactivation timer of a secondary cell; stopping or restarting the timing of the secondary cell deactivation timer when transmitting the SR;
and when the secondary cell deactivation timer expires, performing secondary cell deactivation.
The embodiment of the present application may be applied to the CA scenario, for example, the terminal sets a secondary cell deactivation timer, and deactivates the secondary cell when the secondary cell deactivation timer expires. If the terminal sends the SR during the timing of the secondary cell timer, the SR is used to request a resource, and to avoid failing to receive the downlink control information indicating the resource requested by the SR, the terminal may stop or restart the secondary cell deactivation timer, thereby facilitating the terminal to receive the downlink control information and perform signal transmission on the resource indicated by the downlink control information, and improving the signal transmission performance.
In some possible implementations, the stopping or restarting the timing of the secondary cell deactivation timer when transmitting the SR includes:
stopping or restarting the timing of the secondary cell deactivation timer when the SR is transmitted and the secondary cell deactivation timer distance expires to less than or equal to a first time threshold.
The terminal may determine that the secondary cell deactivation timer is about to end, e.g., a distance from the secondary cell deactivation timer expires less than or equal to a first time threshold within which downlink control information may not be received, such that the terminal may stop or restart timing of the secondary cell deactivation timer to facilitate the terminal being able to receive the downlink control information. That is to say, when the expiration of the timing distance of the secondary cell deactivation timer is greater than the first time threshold, the terminal may not stop or restart the timing of the secondary cell deactivation timer after the terminal sends the SR, so that the deactivation of the secondary cell is not affected, and the power consumption of the terminal is saved.
In some possible implementations, the stopping or restarting the timing of the secondary cell deactivation timer when transmitting the SR includes:
and when the SR is sent and the timing of the secondary cell deactivation timer is greater than a second time threshold value, stopping or restarting the timing of the secondary cell deactivation timer.
The terminal may also determine how much the timing exceeds (e.g., set to the second time threshold) the downlink control information may not be received according to the preset duration of the secondary cell deactivation timer, and thus, the terminal stops or restarts the timing of the secondary cell deactivation timer when the SR is transmitted, thereby helping the terminal to be able to receive the downlink control information.
In some possible implementations, after stopping the timing of the secondary cell deactivation timer when transmitting the SR, the method further includes:
and when receiving downlink control information, continuing the timing of the deactivation timer of the secondary cell, wherein the downlink control information is used for responding to the SR.
If the terminal stops the timing of the secondary cell deactivation timer when transmitting the SR, the terminal continues the timing of the timer when receiving the downlink control information in response to the SR, and deactivates the secondary cell when the secondary cell deactivation timer expires.

2. Multicast Broadcast Single Frequency Network (MBSFN) subframes:
the MBSFN subframe is shared by a plurality of cells, the same data is transmitted by the network equipment on the MBSFN subframe, and the terminal can receive the same data from a plurality of network equipment on the MBSFN subframe.
3. Flexible notation:
if the network device is configured with a flexible symbol, the terminal will not receive downlink data and transmit uplink data on the flexible symbol.
4. Duration timer (on duration timer):
the on duration timer is used to determine a duration of an awake period, the terminal device is in the awake (on duration) period during an operation period of the on duration timer or before the on duration timer expires, and the terminal device may start a receiving antenna to monitor the PDCCH.
It should be understood that the duration timer may also be referred to as an "activity timer".
5. DRX inactivity timer (DRX-inactivity timer)
Specifically, the subframe 0 is the last subframe of the on duration period, and at this time, the network side has exactly one large byte of data to be sent to the UE, and the data cannot be completely sent in the subframe 0. If the operation is performed according to the duration timer, the UE will enter the DRX sleep state in subframe No. 1, and will not monitor the PDCCH any more, nor will it receive any downlink PDSCH data from the network side. The network side can only wait until the DRX period is finished, and when the next 1 duration period comes, the network side continues to send data which is not transmitted to the terminal equipment. Although this type of processing mechanism has no errors, it significantly increases the processing delay of the entire service. In order to avoid this, a DRX-inactivity timer is added to the DRX mechanism. If the drx-inactivity timer is running, even if the originally configured on duration timer expires (i.e., the on duration period ends), the UE still needs to continue monitoring the downlink PDCCH subframe until the drx-inactivity timer expires. After the DRX-Inactivity mechanism is added, the processing time delay of data can be obviously reduced.
6. Discontinuous reception loop time timer (DRX-HARQ-RTT-timer)
When the DRX-HARQ-RTT-timer fails to decode a Transport Block (TB) of a downlink HARQ process (process), the terminal may assume that there is a retransmission at least after the "HARQ RTT" subframe, and therefore the terminal does not need to monitor the PDCCH during the DRX-HARQ-RTT-timer.
7. DRX retransmission timer (DRX retransmission timer)
In the DRX mechanism, the DRX retransmission timer means: and the UE needs to wait for the minimum number of subframes before receiving the expected downlink retransmission data. For Frequency Division Duplex (FDD) -LTE, the value of the HARQ RTT Timer is fixed equal to 8 subframes. For TDD-LTE, the value of HARQ RTT Timer is equal to (k +4) subframes, where k represents the time delay for downlink channel transmission and its response to feedback information. The DRX Retransmission Timer refers to a time length for the UE to monitor the PDCCH to receive data that needs to be retransmitted without transmission success after the HARQ RTT Timer expires.
In the present application, the awake period may include a period corresponding to a period during which at least one timer among the above-mentioned duration timer, DRX-inactivity timer, and DRX transmission timer is operated.
In idle mode, the monitoring function of the PDCCH can adopt DRX mode, so as to reduce power consumption, the DRX working mechanism in idle mode is fixed, a fixed period is adopted, the function of monitoring the PDCCH is started when Paging Occasion (PO) arrives, an active period in idle mode is entered, the PDCCH needs to be monitored completely in the active period, the PDCCH enters sleep state again after the DRX active period elapses, and a Paging Frame (PF) represents a radio frame containing one or more POs; if DRX is used, the terminal device monitors only the PO per DRX cycle. The terminal device will Cycle according to a default DRX Cycle (Cycle) configuration after being powered on. The PDCCH is received when the paging occasion comes.
In the RRC connected state, a working mode combining a timer and DRX is adopted, and the network device also maintains the same DRX working mode as the terminal device and knows in real time whether the terminal device is in an active period or a sleep period, thereby ensuring that data is transmitted in the active period and data transmission is not performed in the sleep period.
8. Secondary cell deactivation timer (scell-deactivation timer):
in a CA scenario, a terminal transmits the same data packet to a network device through two links (i.e., a primary cell and a secondary cell) respectively, so as to ensure reliability of data transmission, and can reduce link overhead of the terminal by deactivating the secondary cell under the condition that reliability of data requirements is low. For example, the terminal sets a secondary cell deactivation timer, and deactivates the secondary cell when the secondary cell deactivation timer expires.
9. Bandwidth part (BWP) -deactivation timer (inactive timer):
the network device may schedule the terminal to transmit on different BWPs according to the data volume transmission requirements of the traffic. In addition, the terminal may control the switching of the BWP by setting a BWP inactive timer, specifically, if the terminal has no data transmission or data scheduling for a long time on a certain activated BWP, the terminal may switch to the initial BWP or default BWP after the BWP inactive timer expires, thereby reducing the power consumption of the terminal; if the terminal has data to send, it does not want BWPinactive timer overtime, that is, BWP switching is not performed.
It should be understood that the above-listed timers are merely exemplary and the present application is not limited thereto.
10. Bandwidth (bandwidth):
bandwidth may be understood as a continuous or discontinuous segment of resources in the frequency domain:
the bandwidth may be referred to as a cell or a carrier. The cell may be a serving cell of the terminal. The serving cell is described by a higher layer from the point of view of resource management or mobility management or serving element. The coverage area of each network device may be divided into one or more serving cells, and the serving cells may be regarded as being composed of certain frequency domain resources, i.e., one serving cell may include one or more carriers. The concept of carrier waves is described from the point of view of signal generation of the physical layer. One carrier is defined by one or more frequency points, corresponds to a continuous or discontinuous section of spectrum, and is used for carrying communication data between the network equipment and the terminal. The downlink carrier may be used for downlink transmission and the uplink carrier may be used for uplink transmission. Optionally, each carrier may include uplink resources and downlink resources, or only include uplink resources, or only include downlink resources. It can also be said that one cell may include multiple downlink carriers and multiple uplink carriers, and the number of uplink carriers and downlink carriers may be unequal. This is not limited in the embodiments of the present application.
The bandwidth may also be referred to as a bandwidth part (BWP), a carrier bandwidth part (carrier bandwidth part), a sub-band (subband) bandwidth, a narrowband (narrowband) bandwidth, or other names, and the application does not limit the names, and the following embodiments do not distinguish different names. A plurality of uplink bandwidth parts may be configured on one uplink carrier, and a plurality of downlink bandwidth parts may be configured on one downlink carrier. Alternatively, the multiple bandwidth parts related to the embodiments of the present application may be located in the same cell or on the same carrier, or may be located in different cells or on different carriers.
Illustratively, one BWP may contain consecutive K (K >0) subcarriers; alternatively, one BWP is a frequency domain resource where N non-overlapping consecutive Resource Blocks (RBs) are located, and the subcarrier spacing of the RBs can be 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz or other values. Alternatively, a BWP is a frequency domain resource where M non-overlapping consecutive Resource Block Groups (RBGs) are located, and a RBG includes P consecutive RBs, and the sub-carrier spacing of the RBs may be 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz or other values, for example, integer multiples of 2.
In this application, the various timers may be configured by a Radio Resource Control (RRC) layer, and after RRC connection establishment or reestablishment is initiated, various parameters required by the MAC layer are configured by a Media Access Control (MAC) main configuration (MAC-mainconfiguration) cell, and then immediately enter a short DRX cycle or a long DRX cycle operation phase.
By way of example and not limitation, the configuration parameters for DRX mode may include, but are not limited to, the following parameters:
DRX period (drx-cycle)
Specifically, the DRX cycle may refer to a length of a DRX cycle, for example, the length of the short DRX cycle, or may refer to a length of the long DRX cycle.
Parameter b time domain position offset of the DRX mode wake-up period
Specifically, for example, in the present application, the starting time of one awake period may coincide with the starting time of the DRX cycle in which the awake period is located, in which case, the time domain position offset of the awake period of the DRX mode may refer to an offset of the starting time of the DRX cycle with respect to a preset reference time. For example, a time domain position offset of the DRX pattern's awake period may indicate a starting time unit (e.g., starting subframe) of the DRX cycle.
It should be noted that, the communication system may be divided into a plurality of system cycles in a time domain, and the time domain position offset of the awake period of the DRX mode may refer to an offset of a start time of a first awake period of the DRX mode relative to a start time of a system cycle in which the start time is located. That is, the preset reference time may refer to a start time of a system cycle in which a first awake period of the DRX mode is located.
Alternatively, the time domain position offset of the DRX mode awake period may be the offset indicated by the DRX start offset parameter.
The awake period may be a period measured by the on duration Timer.
For another example, in the present application, the starting time of one awake period may not coincide with the starting time of the DRX cycle in which the awake period is located, and in this case, the time domain position offset of the awake period in the DRX mode may refer to an offset of the awake period relative to the starting time of the DRX cycle. For example, a time domain position offset of the awake period of the DRX pattern may indicate an offset of the awake period within the DRX cycle.
The awake period may include a period corresponding to any one of the on duration timer, the drx inactivity timer, or the harq rtt timer.
For another example, in the present application, the starting time of an awake period may be a time that satisfies the formula [ (SFN × 10) + subframe number ] mod (long DRX cycle duration) ═ drxStartOffset, where the awake period is a period in which the on duration timer operates.
Fig. 1 is a schematic diagram of a communication system of the present application. The communication system in fig. 1 may include at least one terminal (e.g., terminal 10, terminal 20, terminal 30, terminal 40, terminal 50, and terminal 60) and a network device 70. The network device 70 is configured to provide a communication service to a terminal and access a core network, and the terminal may access the network by searching for a synchronization signal, a broadcast signal, and the like transmitted by the network device 70, thereby performing communication with the network. The terminals 10, 20, 30, 40 and 60 in fig. 1 may perform uplink/downlink transmission directly with the network device 70. Further, the terminal 40, the terminal 50, and the terminal 60 may also be regarded as one communication system, and the terminal 60 may transmit the scheduling information to the terminal 40 and the terminal 60.
Further, the terminal device 40, the terminal device 50, and the terminal device 60 may be regarded as one communication system, and the terminal device 60 may transmit a downlink signal to the terminal device 40 and the terminal device 50, or may receive an uplink signal transmitted by the terminal device 40 and the terminal device 50.
Fig. 2 shows a schematic diagram of an application scenario of an embodiment of the present application. As shown in fig. 2, in order to avoid large power consumption overhead caused by continuously monitoring the PDCCH, a concept of Discontinuous Reception (DRX) is introduced. The terminal monitors the PDCCH only in each downlink subframe within an on duration in each DRX period, and does not monitor the PDCCH during a sleep period in the DRX period, so as to reduce power consumption. For example, a duration timer is started at the start time of the duration, and when the duration timer expires, the terminal stops monitoring the PDCCH.
Specifically, DRX may allow the UE to periodically enter a sleep mode at some time, not monitor the PDCCH, and wake up from the sleep mode when monitoring is needed, so as to achieve the purpose of saving power for the UE.
As shown in fig. 2, in the present application, one DRX cycle may include an awake (on duration) period and a sleep period.
This wake-up period may also be referred to as an active period. The terminal device may communicate with the network device during the wake-up period.
As shown in fig. 2, during the On Duration period, the UE monitors the downlink PDCCH subframe, and during this period, the UE is in an awake state.
The sleep period may also be referred to as a DRX Opportunity (DRX) period. The terminal device may not perform data transmission during the sleep period.
As shown in fig. 2, in the Opportunity for DRX period, the UE goes to sleep without monitoring the time of PDCCH subframes for power saving.
As can be seen from fig. 2, the longer the time for DRX sleep, the lower the power consumption of the UE, but correspondingly, the delay of traffic transmission increases.
In the DRX mechanism, the terminal device may receive downlink data and an uplink grant during an active period. And, the terminal device may perform a cycle of DRX according to a paging cycle in the idle mode. Alternatively, the terminal device may adopt multiple timers to cooperate with each other in a Radio Resource Control (RRC) connected state to ensure reception of the downlink data and the uplink grant. Subsequently, the above timer will be explained in detail.
Communication of large data volumes tends to cause a drastic increase in power consumption, resulting in insufficient supply of batteries or increased heat dissipation due to increased power consumption, resulting in system operation failure. While the use of the DRX functionality greatly reduces power consumption.
In this application, the DRX functional control entity may be located at the MAC layer of the protocol stack, and its main function is to control sending of an instruction to the physical layer, to notify the physical layer to monitor the PDCCH at a specific time, and to keep the receiving antenna from being turned on and in a sleep state at the rest of the time.
By way of example and not limitation, in the present application, DRX cycles may include a short DRX cycle and a long DRX cycle.
Specifically, as described above, one DRX cycle is equal to the sum of an awake (on duration) period and a sleep time. The communication system may configure a short DRX cycle (short DRX cycle) or a long DRX cycle (long DRX cycle) for the UE according to different service scenarios. For example, when performing voice services, a voice codec typically sends 1 voice packet every 20 milliseconds (ms), in which case a short DRX cycle of 20ms can be configured, and a long DRX cycle can be configured during a longer silence period during a voice call.
That is, if the terminal device itself includes the short DRX cycle and the short DRX cycle timer, the terminal device operates according to the short DRX cycle, and enters the long DRX cycle operating state after the short DRX cycle timer expires.
And, entering a long DRX cycle running phase after an active period or after a short DRX ring timer is overtime.
In the present application, the starting time of the DRX cycle, or starting time unit (e.g., starting subframe), may be indicated by a DRX start offset (drxstartoffset) parameter. The value range of DRX start offset can be determined based on the size of the DRX cycle, for example, the DRX cycle includes 10 subframes, and the value range of DRX start offset can be 0-9; if the DRX period comprises 20 subframes, the value range of DRX start offset can be 0-19. For example, if drxstart offset is 0, it indicates that the starting subframe of the DRX cycle is the first subframe in the cycle; for example, if drxstart offset is 8, it indicates that the starting subframe of the DRX cycle is the ninth subframe in the cycle.
Wherein, the starting time (or starting time unit) of the DRX cycle may be equal to or unequal to the starting time (or starting time unit) of the awake period of the DRX cycle.
Fig. 3 shows a schematic diagram of another application scenario of an embodiment of the present application. As shown in fig. 3, during the timing of the secondary cell deactivation timer, the terminal starts or restarts the secondary cell deactivation timer when receiving downlink assignment scrambled by a cell radio network temporary identity (C-RNTI) or a configuration scheduled radio network temporary identity (CS-RNTI) or Downlink Control Information (DCI) of an uplink grant, and a Protocol Data Unit (PDU) data packet of the configuration grant.
The time slice encountered during the on duration timer timing in the scenario shown in fig. 2, or the time slice encountered during the secondary cell deactivation timer timing in the scenario shown in fig. 3, and the failure to receive DCI or PDU within the time slice, all affect the transmission delay of data.
Fig. 4 shows a schematic flow chart of a method of signal processing of an embodiment of the present application.
The execution subject of the embodiment of the present application may be any one of a plurality of terminals, and the following embodiments take the first terminal as an example, which is not limited in the present application.
The plurality of terminals may or may not be in the coverage of the same cell.
401, when a first terminal overlaps with a time slice (overlap) during the timing of a timer, stopping or restarting the timer, where the time slice is a period in which the first terminal does not perform data transceiving with a first network device;
the first terminal performs signal processing when the timer expires 402.
Specifically, the time slice is a time period in which the first terminal and the first network device do not perform data transceiving, the first terminal stops timing of the timer when detecting that the time period of the timer overlaps with the time slice in time, and the timer can be restarted to continue timing when detecting that the time slice is finished, so that the situation that the signal transmission delay is long due to the fact that the timer still times in the time slice can be avoided; or when the first terminal detects that the time period of the timer overlaps with the time slice in time, the first terminal can restart the timer to start timing, so that the signal transmission delay caused by the time slice can be reduced. That is to say, the embodiment of the application can reduce the transmission delay of the signal, and further improve the reliability of data transmission.
It should be noted that, in step 401, the first terminal may stop or restart the timer immediately when detecting that the timing period of the timer overlaps with the time slice, or may stop or restart the timer after a preset time period after detecting that the overlap occurs, which is not limited in this application.
It should be understood that the data in the embodiment of the present application may be data related to a service sensitive to delay, for example, data related to an Ultra Reliable and Low Latency Communication (URLLC) service; or data related to a service that is less sensitive to a delay, for example, data related to an enhanced mobile broadband (eMBB) service and a large machine type communication (mtc) service, which is not limited in this application.
It should also be understood that the timer may be in units of time, minutes, and seconds, or in units of time units, such as time slots, mini-slots, or symbols, which is not limited in this application.
It should also be understood that the timer may be started from a minimum value or a maximum value, and the application is not limited thereto. For example, the timer starts counting from 0 until the maximum value (max ═ 10), or the timer starts counting from the maximum value (max ═ 10) until 0.
Alternatively, the first terminal detecting that the timer period overlaps with the time slice may be detecting the time slice during the timer period.
Specifically, the first terminal may encounter the time slice during the timer counting, and at this time, the first terminal may restart the timer or stop the counting of the timer, so as to avoid being affected by the time slice.
Alternatively, the first terminal detecting that the timer period overlaps with the time slice may be detecting that the timer starts to start counting during the time slice operation.
Specifically, the first terminal encounters a timer for timing after the time slice is set, and the first terminal may stop the timing of the timer, that is, not start the timer, and restart the timer after the time slice is finished.
In one embodiment, the timer may be any one of a discontinuous reception active timer (DRX-on duration timer), a discontinuous reception deactivation timer (DRX-inactive timer), a discontinuous reception retransmission timer (DRX-retransmission timer), a discontinuous reception loop time timer (DRX-HARQ-RTT-timer).
Specifically, as shown in fig. 2, the DRX-duration timer generally starts to count at the beginning of each DRX cycle, during which the first terminal may monitor the PDCCH sent by the first network device, and stops monitoring the PDCCH at the end of the DRX-duration timer, thereby saving power consumption for the first terminal.
The DRX-inactive timer is started after a terminal successfully decodes a PDCCH indicating initially transmitted uplink or downlink data, and counts the number of subframes of the continuous PDCCH which is continuously in an activated state during the timing period of the DRX-inactive timer. That is, the DRX-inactive timer is restarted once when the first terminal has the initial data to be transmitted scheduled.
When the DRX-HARQ-RTT-timer fails to decode a Transport Block (TB) of a downlink HARQ process (process), the terminal may assume that there is a retransmission at least after the "HARQ RTT" subframe, and therefore the terminal does not need to monitor the PDCCH during the DRX-HARQ-RTT-timer.
The terminal may start a DRX-retransmission timer for the HARQ process when the DRX-retransmission timer expires and the corresponding HARQ process received data is not successfully decoded, and may monitor a PDCCH for HARQ retransmission during the DRX-retransmission timer.
It should be noted that the drx retransmission timer may be an uplink timer or a downlink timer. The discontinuous reception loop time timer may be an uplink timer or a downlink timer.
Optionally, the time-slicing may be at least one of an Almost Blank Subframe (ABS) subframe, a Multicast Broadcast Single Frequency Network (MBSFN) subframe, a flexible symbol, or a measurement gap.
Specifically, the network device generally configures an ABS subframe, an MBSFN subframe, a flexible symbol, and the like for the terminal, so that services such as macro-micro networking, multi-hop, or vehicle networking (V2X) can be supported. The dedicated PDCCH and PDSCH of the terminal are not transmitted on the ABS subframe, and only some necessary common signals may be transmitted, so that interference to the neighboring cell may be avoided. The MBSFN subframe is mainly used for transmitting the multicast broadcast MBMS service, and the PDSCH is not transmitted on the MBSFN subframe, so that the interference among cells can be eliminated.
For example, as described below with the DRX-duration timer encountering a measurement GAP, as shown in fig. 5, the terminal starts a timer at time t0, and enters the DRX sleep period at time t2 if the measurement GAP is not encountered. If the measurement GAP is met at the time t1, the terminal may stop the timing of the timer at the time t1 until the time t3 when the measurement GAP is ended, that is, the terminal continues the timing of the timer at the time t3, so that the terminal may enter the DRX sleep period after the DRX-duration timer expires at the time t4, thereby avoiding entering the sleep period at the time t2 so that the terminal needs to wait for the next DRX cycle for signal transmission, and therefore, the embodiment of the application saves data transmission delay.
In another embodiment, the timer may be any one of a secondary cell deactivation timer (cell-deactivation timer) or a bandwidth part (BWP) -deactivation timer (inactive timer).
Specifically, in duplicate transmission (duplicate) of Carrier Aggregation (CA), two links of a primary cell (pcell) and a secondary cell (scell) transmit the same data packet, a first terminal may control deactivation of the secondary cell through a scell-deactivation timer, and after the scell-deactivation timer starts timing, if it is detected that the scell-deactivation timer overlaps with a time slice, the first terminal restarts the scell-deactivation timer, and deactivation processing is performed on the secondary cell until the timing is overtime; or the first terminal stops the cell-deactivation timer, continues timing of the cell-deactivation timer after the time slicing is finished, and deactivates the auxiliary cell until the timing is overtime. That is to say, in the embodiment of the present application, the first terminal reduces the influence on data transmission caused by that the first terminal cannot receive the PDU or the PDCCH and still performs timing of the scell-deactivating timer under the condition of overlapping with the time slicing. For example, the situation that the secondary cell is overtime and then deactivated due to the overlapping of the scell-deactivation timer and the time slice in the link of the secondary cell is avoided, that is, only the link of the primary cell is left to be transmitted, so that the reliability of data transmission is reduced is avoided.
The bandwidth part may include an initial BWP, a default BWP, and an active BWP, and the network device may schedule the terminal to transmit on different BWPs according to the data volume transmission requirement of the service. In addition, the terminal may control the switching of the BWP by setting a bwPinactive timer, specifically, if the terminal has no data transmission or data scheduling for a long time on a certain activated BWP, the terminal may switch to the initial BWP or default BWP after the BWP inactive timer expires, thereby reducing the power consumption of the terminal; if the terminal has data to send, it does not want BWP inactive timer overtime, namely, it does not switch BWP. Therefore, when the timing process of the BWP inactive timer overlaps with the time slicing, the embodiment of the present application may reduce the timeout of the BWP inactive timer caused by the time slicing by stopping or restarting the BWP inactive timer, thereby improving the data transmission performance.
Optionally, the time-slicing may be at least one of an almost blank subframe, a multicast broadcast single frequency network subframe, a flexible symbol, a measurement gap, or a discontinuous reception sleep period.
For example, as shown in fig. 6, the first terminal starts the cell-deactivation timer at time t1 to start timing, and overlaps with the DRX sleep period at time t5, the cell-deactivation timer may stop timing at time t5, and continues to count at time t6 until time t6 at the end of the DRX sleep period, which is described below by taking the cell-deactivation timer as an example of encountering the DRX sleep period, where the cell-deactivation timer expires at time t 7.
Optionally, in this embodiment of the present application, the time slice may also be used for the second terminal to communicate with the second network device, and/or the time slice is used for the second terminal to communicate with the third terminal.
Specifically, the time slicing is to not perform data transceiving between the first terminal and the first network device, but the time slicing may be data transceiving between other terminals or between a terminal and a network device, so that the resource utilization rate is improved.
It should be noted that the second terminal and the first terminal may be the same terminal.
For example, as shown in fig. 7, the time-slicing may be used for data transmission between the second terminal and the second network device. Alternatively, as shown in fig. 8, the time slice may be used for data transmission between vehicles (Vehicle to Vehicle, V2V).
It should be understood that the time slice may be a partial time period for data transmission between other devices (for example, as shown in fig. 8, a partial time period in the time slice is for data transmission between V2V), or may be a full time period for data transmission between other devices, which is not limited in this application.
Optionally, in a case that the timer stops counting the time of the timer, the first terminal may further receive configuration information sent by the first network device, where the configuration information is used to indicate a time at which the timer continues to count the time, so that the timer may continue to count the time at the time indicated by the first network device, thereby further reducing interference. Accordingly, the first network device transmits the configuration information.
Alternatively, during the time period of the timer, if the terminal can perform data transceiving, the timer may stop timing when the terminal overlaps with the time slicing, and data transmission may be performed on the first subframe after the time slicing ends.
Specifically, the terminal may perform uplink data transmission on the first subframe, or may receive downlink data. In addition, the network device may indicate the time domain resources for continuing data transmission through the indication information.
Optionally, the first network device may further transmit indication information indicating signal processing performed by the first terminal after the first timer expires.
Specifically, for example, the indication information may further indicate whether the first terminal monitors the PDCCH after the first timer expires.
Optionally, the indication information may also indicate a time to monitor the PDCCH after the first timer expires. For example, the indication information indicates that data is received in a first subframe after the first timer expires.
Optionally, the indication information may be carried in at least one of Radio Resource Control (RRC) dedicated signaling, Downlink Control Information (DCI), a medium access control element (MAC CE), or RRC common signaling.
Therefore, in the signal processing method according to the embodiment of the present application, when detecting that the time period of the timer overlaps with the time slice in terms of time, the first terminal stops timing of the timer, and when detecting that the time slice is finished, the first terminal restarts the timer to continue timing, so that it is possible to avoid that the signal transmission delay is long due to the fact that the timer still times within the time slice; or when the first terminal detects that the time period of the timer overlaps with the time slice in time, the first terminal can restart the timer to start timing, so that the signal transmission delay caused by the time slice can be reduced. That is to say, the embodiment of the application can reduce the transmission delay of the signal, and further improve the reliability of data transmission.
It should also be understood that, in the present application, "when …", "if" and "if" all refer to the fact that the UE or the base station will perform the corresponding processing under certain objective conditions, and are not limited time, and do not require the UE or the base station to perform certain judgment actions, nor do they mean that there are other limitations.
It should also be understood that in the embodiments of the present application, "B corresponding to a" means that B is associated with a, from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
In a CA scenario, a terminal transmits the same data packet to a network device through two links (i.e., a primary cell and a secondary cell) respectively, so as to ensure reliability of data transmission, and can reduce link overhead of the terminal by deactivating the secondary cell under the condition that reliability of data requirements is low. For example, the terminal sets a secondary cell deactivation timer, and deactivates the secondary cell when the secondary cell deactivation timer expires. However, in the process of operating the secondary cell deactivation timer, the terminal sends the SR, and when the network device feeds back Downlink Control Information (DCI), the secondary cell deactivation timer may have timed out, or even has finished deactivating the secondary cell, so that the terminal cannot receive the DCI, and cannot perform signal transmission on the resource indicated by the DCI, so that the performance of signal transmission is low.
Fig. 9 shows a schematic flow chart of a method of signal processing of another embodiment of the present application.
It should be noted that, unless otherwise specified, the same terms in the embodiments of the present application have the same meanings as those in the embodiments described above, and in order to avoid repetition, the present application will not be repeated.
The terminal 901 transmits a Scheduling Request (SR) during the secondary cell deactivation timer.
902, the terminal stops or restarts the timing of the deactivation timer of the secondary cell when transmitting the SR;
and 903, when the terminal expires the secondary cell deactivation timer, deactivating the secondary cell.
Specifically, the embodiment of the present application may be applied to the CA scenario, for example, the terminal sets a secondary cell deactivation timer, and deactivates the secondary cell when the secondary cell deactivation timer expires. If the terminal sends the SR during the timing of the secondary cell timer, the SR is used to request a resource, and to avoid failing to receive the downlink control information indicating the resource requested by the SR, the terminal may stop or restart the secondary cell deactivation timer, thereby facilitating the terminal to receive the downlink control information and perform signal transmission on the resource indicated by the downlink control information, and improving the signal transmission performance.
It should be noted that the terminal may send the SR actively when the terminal has a resource requirement, or may trigger the terminal to send other information, which is not limited in this application.
Alternatively, if the terminal stops the timing of the secondary cell deactivation timer when transmitting the SR, the terminal continues the timing of the timer when receiving the downlink control information in response to the SR, and deactivates the secondary cell when the secondary cell deactivation timer expires.
Optionally, step 902 may specifically be that the terminal stops or restarts the timing of the secondary cell deactivation timer when the terminal transmits the SR and when the secondary cell deactivation timer distance expires and is less than or equal to the first time threshold.
Specifically, the terminal may determine that the secondary cell deactivation timer is about to end, e.g., a distance from the secondary cell deactivation timer expires less than or equal to a first time threshold within which downlink control information may not be received, so that the terminal may stop or restart timing of the secondary cell deactivation timer, thereby facilitating the terminal to be able to receive the downlink control information. That is to say, when the expiration of the timing distance of the secondary cell deactivation timer is greater than the first time threshold, the terminal may not stop or restart the timing of the secondary cell deactivation timer after the terminal sends the SR, so that the deactivation of the secondary cell is not affected, and the power consumption of the terminal is saved.
For example, as shown in fig. 10, the secondary cell deactivation timer is at t1Starting the time, wherein the preset time length of the deactivation timer of the auxiliary cell is t when the time reaches3Ending at time t during secondary cell deactivation timer timing2At that time, the terminal transmits an SR t2Time t and3the time interval of the time is less than or equal to the first time threshold, the terminal stops or restarts the timing of the secondary cell deactivation timer until t4At that time, when the terminal receives the downlink control information in response to the SR, the terminal may continue the timing of the secondary cell deactivation timer, at t5And at the moment, when the secondary cell deactivation timer expires, the terminal deactivates the secondary cell.
It should be noted that, in the following description,the first time threshold may be set by a terminal or may be configured by a network device. For example, the terminal may set according to a time duration between the last time of transmitting the SR and the time of receiving the downlink control information, for example, as shown in fig. 10, the first preset threshold is t4-t2The value of (c).
Optionally, step 902 may also be that the terminal stops or restarts the timing of the secondary cell deactivation timer when transmitting the SR and when the timing of the secondary cell deactivation timer is greater than the second time threshold.
Specifically, the terminal may also determine how much the timing exceeds (e.g., set to the second time threshold) according to the preset duration of the secondary cell deactivation timer, so that the terminal stops or restarts the timing of the secondary cell deactivation timer when the SR is transmitted, thereby facilitating the terminal to be able to receive the downlink control information.
For example, as shown in fig. 10, the terminal may set the second time threshold to a value of t3- (t4-t2), i.e., the time remaining for deactivating the timer cannot receive the downlink control information.
Therefore, in the signal processing method according to the embodiment of the present application, the terminal sends the SR during the timing of the secondary cell timer, the SR is used to request a resource, and to avoid failing to receive the downlink control information indicating the resource requested by the SR, the terminal may stop or restart the secondary cell deactivation timer, thereby facilitating the terminal to receive the downlink control information and perform signal transmission on the resource indicated by the downlink control information, and improving the signal transmission performance.

It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.

The method of signal processing according to the embodiment of the present application is described above in detail, and the apparatus of signal processing of the embodiment of the present application will be described below.

Optionally, the timer is any one of a discontinuous reception active timer, a discontinuous reception deactivation timer, a discontinuous reception retransmission timer, a discontinuous reception loopback time timer, a secondary cell deactivation timer, or a bandwidth partial deactivation timer.
Optionally, in case the timer is any one of a discontinuous reception active timer, a discontinuous reception deactivation timer, a discontinuous reception retransmission timer, or a discontinuous reception loopback time timer, the time slice includes at least one of an almost blank subframe, a multicast broadcast single frequency network subframe, a flexible symbol, or a measurement gap.

when the timer expires, the control transceiver module 1120 stops transceiving data with the first network device; or
When the timer expires, performing a handover of the bandwidth part; or
Upon expiration of the timer, secondary cell deactivation is performed.
Therefore, in the signal processing device according to the embodiment of the present application, when it is detected that the time period of the timer overlaps with the time slice in terms of time, the timer is stopped to time, and when it is detected that the time slice is finished, the timer is restarted to continue to time, so that it is possible to avoid that the signal transmission delay is long due to the fact that the timer still times in the time slice; or when the time overlap between the time slice and the timer counting period is detected, the timer can be restarted to start counting, so that the signal transmission delay caused by the time slice can be reduced. That is to say, the embodiment of the application can reduce the transmission delay of the signal, and further improve the reliability of data transmission.
