Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wireless communication, and particularly relates to a transmission method and device under discontinuous reception. BACKGROUND

[0002] Long Term Evolution (LTE) and New Radio (NR) both introduce Discontinuous Reception (DRX) mechanism, which achieves power saving of User Equipment (UE, also known as terminal) by configuring DRX on and off time. As shown in FIG. 1, the on duration is the interval of DRX on, and if there is no scheduling, the UE will enter the off duration of a DRX cycle after the on duration. Figure 1

[0003] In LTE sidelink (SL), resource selection needs to be performed through sensing. Please refer to 3GPP TS 36.213, the basic working principle is as follows: measurement is performed in the sensing window, and scheduling assignment (SA) is demodulated and interference measurement is performed in each Transmission Time Interval (TTI). The UE performs resource selection according to the following steps: Figure 2

[0004] a) Exclude the resources in which the UE transmits data.

[0005] b) Demodulate the received SA to obtain the resources reserved by other UEs, and exclude the resources reserved by other UEs.

[0006] c) Perform energy detection in the sensing window to measure the reference signal strength indication (RSSI), and exclude the resources with large interference according to the measurement result.

[0007] d) In the selection window, randomly select a subframe from the 20% of the resources with the smallest interference for periodic resource reservation.

[0008] ​​In a mode 2 resource allocation mode, the NR sidelink supports resource selection based on sensing, which works as follows: 1) a transmitting (TX) UE determines a resource selection window after resource selection is triggered. 2) Before resource selection, the UE needs to determine a candidate resource set, and compare the measured reference signal receiving power (RSRP) on the resources in the resource selection window with the corresponding RSRP threshold. If the RSRP is lower than the RSRP threshold, the resource can be included in the candidate resource set. 3) After the resource set is determined, the UE randomly selects a transmission resource in the candidate resource set. In addition, the UE can reserve a transmission resource for the next transmission during the current transmission.

[0009] The NR sidelink introduces a DRX mechanism to achieve the purpose of power saving. In order to guarantee the reliability of the transmission service, the terminal needs to perform sensing or measurement in the DRX inactive state. However, if the terminal is allowed to perform sensing and / or measurement in the DRX inactive state as in the active state, and the sensing or measurement behavior is not limited, the power saving effect of the DRX may be weakened, and the purpose of introducing the DRX mechanism cannot be achieved. Therefore, it is necessary to study the sensing and / or measurement behavior in the DRX inactive state, so as to guarantee the reliability of the service while achieving the purpose of energy saving.

[0040] Figure 3 ​A block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network side device 12. The terminal 11 can also be referred to as a terminal device or a user terminal (UE).

The base station is not limited to a specific technical term, and it should be noted that only a base station in an NR system is taken as an example in the embodiments of the present application, but the specific type of the base station is not limited.

[0041] First, some technical terms related to the present application are briefly described below.

[0042] 1. Introduction of DRX

[0043] When DRX is configured, the parameters of onDurationTimer (DRX active timer), drx-InactivityTimer (DRX inactivity timer), drx-RetransmissionTimer (DRX retransmission timer), longDRX-CycleStartOffset, etc. are configured.

[0044] After DRX is configured, if the UE fails to decode the transmitted or received data, the UE needs to enter the active time to monitor the control channel and wait for the network to schedule retransmission.

[0045] During the On Duration, if the UE is scheduled and receives data in a certain slot, it is likely to continue to be scheduled in the next few slots. Therefore, every time the UE is scheduled to transmit data, the drx-InactivityTimer is started or restarted, and the UE will remain in the active state until the timer expires.

[0046] For downlink data reception, after receiving the downlink data transmission indicated by the Physical Downlink Control Channel (PDCCH) and feeding back the Hybrid automatic repeat request acknowledgement (HARQ) information, the UE starts the downlink HARQ RTT (Round Trip Time) Timer for the corresponding HARQ process. If the data of the HARQ process is not successfully decoded after the HARQ RTT Timer expires, the UE starts the drx-RetransmissionTimer and monitors the PDCCH to wait for transmission.

[0047] For uplink data transmission, after receiving the PDCCH indicating uplink data transmission, the UE starts the uplink HARQ RTT Timer for the corresponding HARQ process. After the HARQ RTT Timer expires, the UE starts the drx-ULRetransmissionTimer and enters the active state to monitor the PDCCH to wait for network scheduling.

[0048] 2、Partial sensing in LTE SL

[0049] The partial sensing in LTE V2X is mainly designed for power saving, and is used to support the communication between pedestrian UE and vehicle UE (P2V). The UE supports two modes of resource selection. One is random resource selection, and the other is partial sensing first, and then resource selection based on the result of partial sensing, and semi-static resource reservation. Among them, which mode is selected by the UE is configured by the radio resource control (RRC). When the RRC is configured to support both modes of resource selection, the UE decides which resource selection mode to use.

[0050] Specifically, please refer to Figure 4 The partial sensing and resource selection of the terminal are as follows:

[0051] The UE detection window is a window of the stripe part in the range of [n-1000, n], the length Y and k are RRC configured parameters, and the value range of k can be {1, 2, 3, …, 10}. The grid window in [n+T1, n+T2] is the selection window of the UE configured by the higher layer. The UE detects the sidelink control information (SCI) sent by other terminals in the detection window of the stripe, and according to the detected SCI and the reservation period, it can infer the resource reservation of other terminals in the grid window. The UE can exclude the resources in the selection window that do not meet the conditions according to these information. In the remaining resources, at least 20% (20% of the window length Y) of the resources are selected as a candidate resource set, which is reported to the media access control (MAC) layer. The MAC layer randomly selects a resource from the candidate resource set as the candidate resource of the UE. The UE performs periodic reservation on the selected resource, and the reservation period is indicated in the SCI.

[0052] 3. Random selection in SL

[0053] If the user performs random selection, the resource is randomly selected in the selection window, and sensing is not required.

[0054] In Rel-16 NR SL, TX UEs reserve their allocated resources (reservation is divided into periodic reservation and aperiodic reservation). Reserved resources are used for future Physical Sidelink Control Channel (PSCCH) / Physical Sidelink Shared Channel (PSSCH) transmissions. Aperiodic reservation can be implemented through the Time resource assignment field in the SCI, and the reserved resources can be used for at least the same TB of transmission. Periodic reservation can be implemented through the Resource reservation period field in the SCI, and the periodically reserved resources in the current period can be used for the transmission of the next TB.

[0055] 4. Resource pre-emption in NR SL

[0056] In Mode 2 resource allocation, a resource pre-emption mechanism is supported, which is briefly described below. If a UE's reserved or selected resources overlap (or partially overlap) with resources reserved or selected by other UEs with higher-priority services, and the UE's SL-RSRP measurement value on the relevant resource exceeds a certain associated SL-RSRP threshold, the UE will trigger a resource reselection. The service priority and the SL-RSRP threshold are determined by TB transmissions on the resource.

[0057] like Figure 5 As shown, in order to determine whether the reserved or selected resources (PSCCH or PSSCH resources) have been preempted, the UE will re-evaluate the resource selection at least at time 'm-T3'. Time 'm' is the time when the resource is located or the time when the resource reservation information is sent, and T3 includes at least the time during which the UE performs the resource selection process.

[0058] The following description, in conjunction with the accompanying drawings, details the transmission method and apparatus for discontinuous reception provided in this application through some embodiments and application scenarios.

[0059] It should be noted that in this application, "sensing" can refer to receiving the Physical Sidelink Control Channel (PSCCH) or Sidelink Control Information (SCI), etc.

[0060] The partial sensing can include at least one of periodic-based partial sensing (PBPS) and contiguous partial sensing (CPS).

[0061] In the present application, a time unit can be expressed as a symbol, a time slot, a subframe, a frame, a millisecond, a second, a number of times, etc.

[0062] Please refer to Figure 6 , Figure 6 A flowchart of a transmission method in a discontinuous reception of an embodiment of the present application is shown. The method comprises the following steps:

[0063] Step 61: When a first preset condition is met, the terminal detects (senses) and / or measures in a DRX inactive state, or when a second preset condition is met, the terminal does not detect and / or measure in the DRX inactive state.

[0064] And / or

[0065] Step 62: When the terminal detects and / or measures in the DRX inactive state, a third preset condition is met.

[0066] In an embodiment of the present application, the specific behavior of the terminal detecting (sensing) and / or measuring in the inactive state is specified, so that when the terminal detects and / or measures in the DRX inactive state, the purpose of energy saving is achieved, while the reliability of the service is guaranteed.

[0067] In an embodiment of the present application, the first preset condition and / or the second preset condition includes at least one of the following:

[0068] 1) The priority of the data packet or service is higher than or equal to a first priority threshold value;

[0069] For example, if the priority of the data packet or service is higher than the first priority threshold (or the priority value is lower than the threshold value), the terminal detects and / or measures in the inactive state. In an embodiment of the present application, optionally, the smaller the value of the priority, the higher the priority.

[0070] 2) The priority of the data packet or service is lower than or equal to a second priority threshold value;

[0071] For example, if the priority of the data packet or service is lower than the second priority threshold (or the priority value is higher than the threshold value), the terminal does not detect and / or measure in the inactive state. In an embodiment of the present application, optionally, the smaller the value of the priority, the higher the priority.

[0072] 3) a packet delay budget (PDB) is less than or equal to a first PDB threshold value;

[0073] In the embodiments of the present application, when the PDB is small, the data packet needs to be sent out in time, and therefore detection and / or measurement can be performed in the inactive state to improve the transmission reliability of the data packet.

[0074] 4) the PDB is greater than or equal to a second PDB threshold value;

[0075] In the embodiments of the present application, when the PDB is large enough, the data packet can be sent after detection in the on-duration time, and detection in the DRX inactive state is not needed.

[0076] 5) the terminal is located in a specific resource pool;

[0077] Optionally, the specific resource pool is a predefined, preconfigured or configured resource pool. For example, when the terminal is configured in a resource pool that is more inclined to power saving, detection and / or measurement in the DRX inactive state is not needed. If the terminal is configured in a resource pool that is more inclined to guarantee reliability, detection and / or measurement in the DRX inactive state is needed.

[0078] 6) the secondary terminal provides the terminal with assistance information;

[0079] For example, the secondary UE can provide the terminal with recommended resources, non-recommended resources and / or detected resource conflicts, and the terminal can rely on the assistance information to select resources, so that detection and / or measurement in the inactive state is not needed.

[0080] In the embodiments of the present application, when the second preset condition is met, the terminal does not perform detection and / or measurement in the DRX inactive state, including: when the secondary terminal provides the terminal with assistance information, the terminal does not perform detection and / or measurement in the DRX inactive state.

[0081] In the embodiments of the present application, when the first preset condition is met, the terminal performs detection and / or measurement in the DRX inactive state, including:

[0082] When the secondary terminal provides the terminal with assistance information, and at least one of the priority, QoS and PDB of the assistance information meets a corresponding threshold value, the terminal performs detection and / or measurement in the DRX inactive state;

[0083] or

[0084] When the secondary terminal provides the terminal with assistance information, and at least one of the priority, QoS and PDB of the data packet meets a corresponding threshold value, the terminal performs detection and / or measurement in the DRX inactive state.

[0085] 7) the second parameter satisfies a fourth preset condition, the second parameter comprises at least one of the following: a power saving mode, a resource allocation scheme, a DRX cycle, a DRX on duration time length, a ratio of the DRX on duration time length to the DRX cycle, a DRX inactive state time length, a ratio of the DRX inactive state time length to the DRX cycle, a data packet transmission cycle, an electric quantity of the terminal, a priority of a data packet or a service, and the first measurement quantity.

[0086] Optionally, in the embodiments of the present application, the first measurement quantity comprises at least one of the following: a QoS of a system, a carrier, a bandwidth part (BWP), a resource pool, a user or a connection group, a channel occupancy rate (CR), a channel occupancy amount, a channel busy rate (CBR), a channel blocking rate, a channel blocking amount, a channel idle rate, a channel idle amount, an ACK number, a data packet transmission success number, a data packet transmission success rate, a NACK number, a data packet transmission failure number, a data packet transmission failure rate, a DTX number, a missed detection number of detection, and a false detection number of detection.

[0087] That is, each of the first measurement quantities described above can be a first measurement quantity of a system, a carrier, a BWP, a resource pool, a user or a connection group.

[0088] Optionally, in the embodiments of the present application, the fourth preset condition comprises at least one of the following:

[0089] 1) a value of the second parameter is greater than or equal to a first threshold value;

[0090] 2) the value of the second parameter is less than or equal to a second threshold value;

[0091] For example, when the CBR or the CR is greater than the first threshold value, it indicates that the system congestion degree is large, at this time, detection needs to be detected to guarantee the transmission reliability, and therefore, the terminal is allowed to detect and / or measure in the inactive state. Conversely, when the CBR or the CR is less than the second threshold value, it indicates that the system congestion degree is low, and the energy consumption of the terminal can be preferentially guaranteed, and therefore, the terminal is not allowed to detect and / or measure in the inactive state.

[0092] Alternatively, when the data packet transmission success rate is greater than the first threshold value, or the failure rate is less than the second threshold value, it indicates that the transmission reliability is high at this time, and therefore, the terminal is not allowed to detect and / or measure in the inactive state. Alternatively, when the data packet transmission success rate is less than the second threshold value, or the failure rate is greater than the first threshold value, it indicates that the transmission reliability is low at this time, and therefore, the terminal is allowed to detect and / or measure in the inactive state.

[0093] 3) the level of the second parameter is greater than or equal to a third threshold value;

[0094] 4) the level of the second parameter is less than or equal to a fourth threshold value;

[0095] For example, when the battery level or power level is greater than the third threshold value, it means that the terminal does not need to consider power consumption at this time, and therefore the terminal can be allowed to detect and / or measure in the inactive state; on the contrary, when the battery level or power level is less than the fourth threshold value, it means that the terminal power is low at this time, and the problem of battery life needs to be prioritized, and the terminal can be prohibited from detecting and / or measuring in the inactive state.

[0096] 4) the terminal is located in a specific mode or mechanism.

[0097] For example, when the terminal is located in a power saving mode or resource allocation mechanism that prioritizes power related issues, the terminal is not allowed to detect and / or measure in the inactive state, or is located in a power saving mode or resource allocation mechanism that prioritizes transmission reliability, and the terminal is allowed to detect and / or measure in the inactive state.

[0098] In the embodiments of the present application, at least one of the first threshold value, the second threshold value, the third threshold value and the fourth threshold value is predefined by a protocol, preconfigured by a network, configured by a network, indicated by a network, preconfigured by a terminal, configured by a terminal or indicated by a terminal. The first threshold value and the second threshold value can be the same threshold value or independently configured threshold values, and the third threshold value and the fourth threshold value can be the same threshold value or independently configured threshold values.

[0099] In the embodiments of the present application, optionally, the first preset condition, the second preset condition and / or the third preset condition include that a first parameter for detecting and / or measuring in the DRX inactive state on each terminal or each communication link or each terminal communication group satisfies at least one of a preset maximum value and a preset minimum value. When the third preset condition is met, the terminal stops or continues to detect and / or measure in the inactive state. Wherein, the communication link refers to the link between the sending terminal and the receiving terminal and the sending terminal and the receiving terminal.

[0100] In the embodiments of the present application, optionally, the first parameter includes at least one of the following: the number of transport blocks (TB), the number of sidelink processes, the number of HARQ processes, the number of MAC PDUs, the number of periodic partial sensing (PBPS) detection periods, the number of PBPS detection occasions, and the number of contiguous partial sensing (CPS).

[0101] In an embodiment of the present application, optionally, at least one of the preset maximum value and the preset minimum value is predefined by a protocol, preconfigured by a network, configured by a network, indicated by a network, preconfigured by a terminal, configured by a terminal, or indicated by a terminal.

[0102] In an embodiment of the present application, optionally, at least one of the preset maximum value and the preset minimum value is related to at least one of the following second parameters: a power saving mode, a resource allocation scheme, a DRX cycle, a DRX on duration time length, a ratio of the DRX on duration time length to the DRX cycle, a DRX inactive state time length, a ratio of the DRX inactive state time length to the DRX cycle, a transmission cycle of a data packet, an electric quantity of the terminal, a priority of a data packet or a service, and the first measurement quantity.

[0103] In an embodiment of the present application, optionally, the first measurement quantity includes at least one of the following: a QoS of a system, a carrier, a bandwidth part (BWP), a resource pool, a user or a connection group, a channel occupancy rate (CR), a channel occupancy quantity, a channel busy rate (CBR), a channel blocking rate, a channel blocking quantity, a channel idle rate, a channel idle quantity, a number of ACKs, a number of successful data packet transmissions, a successful data packet transmission rate, a number of NACKs, a number of failed data packet transmissions, a failed data packet transmission rate, a number of DTXs, a number of missed detections, and a number of false detections.

[0104] The power saving mode can be a corresponding limit set at a preset level, for example, there is a threshold for the sensing time of the terminal in the DRX inactive state at level 1, and there is another threshold at level 2; or in other words, the terminal is allowed to perform a receiving operation at level 2, and is allowed to perform sensing, measurement, and receiving at level 3, by not performing sensing, measurement, and receiving for power saving at level 1; or it can be a preset mechanism for transmission or reception, for example, random selection is a power saving mode, partial detection is a power saving mode, and full detection is another power saving mode.

[0105] In an embodiment of the present application, optionally, the first preset condition, the second preset condition, and / or the third preset condition includes that, within a first time window or a first timer, a first measurement parameter of the terminal or a sidelink process or a HARQ process or a communication link or a communication group is not less than a fifth threshold and / or not greater than a sixth threshold. In this embodiment, by defining the fifth threshold within a period of time, it is ensured that the terminal will at least perform detection and / or measurement, thereby enhancing reliability, and by defining the sixth threshold, the detection and / or measurement behavior of the terminal is limited, thereby achieving the purpose of power saving.

[0106] In an embodiment of the present application, optionally, the first measurement parameter comprises at least one of: a duration of detection and / or measurement, a number of detections and / or measurements, a number of times of switching from a sleep state to a wake-up state, a battery or power level, a first measurement quantity.

[0110] In an embodiment of the present application, optionally, the first measurement parameter is calculated only in a non-active state period within the first time window or the first timer, or is calculated in all periods within the first time window or the first timer.

[0111] In an embodiment of the present application, optionally, a time domain of the first time window is continuous or discontinuous (for example, skipping time in an active state).

For example, when the resource allocation mode of the terminal is random selection, no detection and / or measurement is performed, when the detection mode of the terminal is PBPS, detection and / or measurement is performed based on PBPS, etc.

[0121] Only PBPS-based detection and / or measurement is performed; i.e. when detection and / or measurement is performed in inactive state, it is only performed in the corresponding time belonging to PBPS, or only when the resource detection mechanism is PBPS, detection and / or measurement can be performed in inactive state.

[0122] Only CPS-based detection and / or measurement is performed; i.e. when detection and / or measurement is performed in inactive state, it is only performed in the corresponding time belonging to CPS, or only when the resource detection mechanism is CPS, detection and / or measurement can be performed in inactive state.

[0125] In the embodiments of the present application, optionally, the transmission method in the discontinuous reception further includes at least one of the following:

[0126] 1) Based on PSSCH measurement RSRP;

[0127] The protocol predefinition, network side preconfiguration, network configuration, network indication, terminal preconfiguration, terminal configuration or terminal indication is based on PSSCH measurement RSRP, that is, consistent with the measurement object of the CBR and / or CR and / or the like measurement behavior, so that when the RRC layer continuously measures the CBR and / or CR and / or the like based on the PSSCH or the physical layer measures the CBR and / or CR based on the PSSCH, the terminal does not need to additionally measure the PSCCH to obtain the RSRP. For example, PSSCH measurement RSRP is not allowed or configured, so as to be consistent with the measurement object of the CBR and / or CR and / or the like measurement behavior, thereby achieving the purpose of power saving.

[0128] 2) The RRC layer performs measurement based on PSCCH.

[0129] The protocol predefinition or network side preconfiguration RRC layer can perform measurement based on PSCCH, so that when the RRC layer triggers measurement, it can be consistent with the physical layer when the physical layer performs measurement behavior based on PSCCH, so that the RRC layer does not need to additionally measure PSSCH when the physical layer measures PSCCH, thereby achieving the purpose of power saving by reducing the measurement object.

[0130] The transmission method under discontinuous reception of the present application will be described below with reference to specific embodiments.

[0131] Embodiment one of the present application:

[0132] By setting the first preset condition, the terminal is allowed to detect and / or measure in the DRX inactive state when the terminal meets the first preset condition, or is prohibited from detecting and / or measuring in the DRX inactive state, which can achieve the purpose of power saving. At the same time, through reasonable design of the condition, the reliability of transmission can also be guaranteed.

[0133] For example: when the PDB of the data packet of the terminal is large enough, the terminal can wait until the on-duration time to perform sensing before transmitting the data packet, and does not need to perform sensing in the inactive state. When the PDB is small, the terminal cannot wait for a long time, and in order to guarantee the reliability of transmission, the terminal can be allowed to perform sensing in the inactive state. Therefore, only allowing the terminal whose PDB is less than the threshold to perform sensing in the inactive state can achieve the purpose of power saving from the overall point of view, and also guarantee the reliability of data packet transmission.

[0134] Alternatively, when the auxiliary UE provides the terminal with auxiliary information, the auxiliary UE can provide the terminal with recommended resources, non-recommended resources and / or detected resource conflicts, and the terminal can select appropriate resources to transmit data packets according to the auxiliary information, so as to not need to perform sensing and / or measurement in the inactive state, and also guarantee the reliability of transmission.

[0135] Alternatively, the terminal's detection and / or measurement can be adjusted based on the judgment of the first measurement, such as CBR or CR, transmission success rate, failure rate, etc. For example, if CBR or CR is greater than a threshold, it indicates that the system congestion is relatively high, and sensing is needed to ensure transmission reliability. Therefore, sensing or measurement in the inactive state is allowed. Conversely, if CBR or CR is less than a threshold, it indicates that the system congestion is relatively low, and the terminal's energy consumption can be prioritized. Therefore, detection and / or measurement in the inactive state is not allowed. Alternatively, if the transmission success rate is greater than a threshold or the failure rate is less than a threshold in the first measurement, it indicates that the transmission reliability is relatively high. Therefore, detection and / or measurement in the inactive state is not allowed. Conversely, if the transmission success rate is less than a threshold or the failure rate is greater than a threshold, it indicates that the transmission reliability is relatively low, and detection and / or measurement in the inactive state is needed to ensure performance. Therefore, the terminal is allowed to perform detection and / or measurement in the inactive state.

[0136] Embodiment 2 of the present invention:

[0137] When limiting detection and / or measurement activities in the inactive state for power saving purposes, this can be achieved by limiting the number of data packets or HARQ processes that the terminal can perform in the inactive state. In other words, by reducing or limiting the number of entities associated with detection and / or measurement activities, energy consumption is lowered, or when the number reaches a certain threshold, its further increase is limited, thereby saving energy. Similarly, when considering a communication link or a communication group, power saving can be achieved by considering the overall number of detection and / or measurement activities.

[0138] Embodiment 3 of the present invention:

[0139] like Figure 7 As shown, when the terminal resource allocation mechanism is partial detection, there are three detection opportunities for resource pool configuration or network configuration detection, i.e., k=1,2,3, and the length of each window is 10 time slots. In order to limit the detection and / or measurement actions of the terminal in the inactive state, thereby achieving the purpose of saving power, a first time window and a corresponding threshold can be set.

[0140] The specific value of the first threshold is set based on the power saving mode, resource allocation mechanism, DRX cycle, DRX on duration, the ratio of DRX on duration to DRX cycle, DRX inactive state duration, the ratio of DRX inactive state duration to DRX cycle, data packet transmission cycle, the terminal's power consumption, the priority of data packets or services, and the first measurement quantity.

[0141] For example, a first threshold can be set to 20 slots. The duration of terminal detection is recorded as the first measurement parameter. When the first threshold of 20 slots is reached, no further detection of resources is performed. Figure 7 As shown, based on the first threshold, it can be inferred that the terminal can only perform detection at positions k=1 and k=2. Alternatively, since the terminal can always perform detection in the on-duration state, and the first measurement parameter only calculates the detection duration in the inactive state, it can be determined that the terminal can perform detection at positions k=1 and k=3 in the inactive state. Therefore, the terminal can perform detection at positions k=1, k=2, and k=3 in this case.

[0142] For example, if the first threshold is set to 2 times of waking up, it can be deduced that the terminal can only perform detection at positions k=1 and 2. Alternatively, if the terminal can always detect in the on-duration state, and the number of wake-ups is only counted when waking up from the inactive state and not when transitioning from the inactive state to the on-duration state, then the terminal can perform detection at positions k=1, 2, and 3.
