Description

[Technical field]

[0001] The present application relates to the technical field of mobile communication, and in particular to a discontinuous reception method, device and terminal. [Background technology]

[0002] Sidelink transmission is mainly divided into several transmission methods such as broadcast, groupcast, and unicast. Among them, unicast is one-to-one transmission, groupcast is one-to-many transmission, and broadcast is also one-to-many transmission, but broadcast has no concept that terminals (User Equipment, UE) belong to the same group. Currently, sidelink unicast and groupcast communication support the physical layer Hybrid Automatic Repeat Request (HARQ) feedback mechanism.

[0003] There are two types of resource allocation modes for sidelink UE. 1) Base station scheduling mode (Mode 1): BS schedules SL resource(s) to be used by UE for SL transmission(s). Resources are allocated to each UE under the control of network side equipment, e.g., base station. 2) UE self-determination mode (Mode 2): UE determines, e.g., BS does not schedule, SL transmission resource(s) within SL resources configured by BS / network or pre-configured SL resources. Each UE selects resources by itself.

[0021] Hereinafter, the discontinuous receiving method provided in the embodiments of the present application will be described in detail with reference to the drawings according to several embodiments and their use cases.

[0022] 2 shows a flowchart of a discontinuous reception method provided in an embodiment of the present application. As shown in FIG. 2, the method may be executed by a first terminal, specifically by software or hardware implemented in the first terminal. The first terminal is a receiver in a sidelink and receives data transmitted from a second terminal as a transmitter. The method may include the following step S201.

[0023] In step S201, discontinuous reception based on a sidelink is performed for the second terminal using first instruction information and / or first configuration information for discontinuous reception, the first configuration information including configuration information for a timer, the timer for instructing the first terminal whether or not it is necessary to monitor control signaling and / or data from the second terminal, and the first instruction information including sidelink control information (SCI) for instructing the first terminal of first resources and / or feedback resources for receiving initial transmission and retransmission.

[0024] The first configuration information for DRX acquired by the first terminal includes a configuration related to a HARQ round-trip time (RTT), and specifically includes configuration information of each timer, for example, configuration information of a first timer or a second timer. Here, during the operation period of the first timer, the first terminal does not need to monitor related control signaling in a channel and / or data transmitted from a second terminal, and the first timer may be specifically represented as Drx-HARQ-RTT-TimerSL. During the operation period of the second timer, the first terminal needs to monitor related control signaling in a channel and / or data transmitted from a second terminal, and the second timer may be specifically represented as DRX-RetransmissionTimerSL.

[0025] It should be understood that the first timer Drx-HARQ-RTT-TimerSL:sidelink is for indicating how long to wait before receiving a retransmission after sending a feedback message, and has a similar function to the drx-HARQ-RTT-Timer of Uu. The naming here is for illustrative purposes only.

[0026] The second timer Drx-RetransmissionTimerSL:sidelink is for indicating that the Physical Sidelink Control Channel (PSCCH) or the Physical Sidelink Shared Channel (PSSCH) needs to be monitored to monitor possible retransmissions, and is similar to the function of the drx-RetransmissionTimer of Uu. The naming here is just an example.

[0027] The first indication information is for indicating the reserved first resource for the first terminal to receive the initial transmission and retransmission, and as shown in FIG. 3, the location of the dotted block is the reserved first resource indicated by the first indication information.

[0028] Correspondingly, when the second terminal performs resource selection or re-selection, the second terminal determines a second resource corresponding to the first terminal not needing to monitor control signaling and / or data according to the first configuration information and / or the resource in which the received feedback information is located, and then performs resource selection or re-selection according to the second resource. The control signaling includes a PSCCH and / or an SCI on a PSSCH.

[0029] Thus, an embodiment of the present application provides a discontinuous reception method, and performs sidelink-based discontinuous reception for a second terminal using first configuration information and / or first instruction information for discontinuous reception, thereby enabling the first terminal to accurately receive control signaling and / or data transmitted from the second terminal.

[0030] FIG. 4 shows another flowchart of the discontinuous receiving method provided in an embodiment of the present application, as shown in FIG. 4, the method includes the following step S401.

[0031] In step S401, when the first configuration information includes configuration information of a first timer and / or configuration information of a second timer, discontinuous reception based on a side link is performed based on the first timer, the first timer is for instructing the first terminal that there is no need to monitor control signaling and / or data from the second terminal during the first timer operation period, the configuration information of the first timer includes a first time length for instructing the time length of the first timer, and the second timer is for instructing the first terminal that there is a need to monitor control signaling and / or data from the second terminal during the second timer operation period.

[0032] In one embodiment, the first configuration information includes explicit first timer configuration information and / or second timer configuration information, i.e., a first duration of the first timer Drx-HARQ-RTT-TimerSL and / or a second duration of the second timer Drx-RetransmissionTimerSL are configured in the first configuration information, in units of milliseconds (ms) or slots.

[0033] wherein the first length of time is: the time length between two adjacent first resources; A time length between the feedback transmission channel location resource and the next first resource; Deployment by base station, Placement by protocol, The second terminal is determined by at least one of the configurations.

[0034] In other words, as shown in FIG. 3, in one embodiment, the first time length may be the length between two adjacent point-like clusters.

[0035] In another embodiment, the first time length may be the length between the diagonal block and the next dotted block, at which time the on time of the first timer is after the feedback transmission channel resource.

[0036] In another embodiment, the first amount of time may be a numerical value configured by a base station, a terminal or a protocol, and has a unit of ms or slots.

[0037] Furthermore, in step S401, turning on the first timer at a first time; turning on a second timer when the first timer exceeds the first time period; The first time period is After the first resource in the n-1th row, After the first number of symbols or slots have elapsed after the n-1th first resource, After the resource containing the feedback information sent for the first resource (n-1), At least one item after a second quantity of symbols or slots have elapsed after the resource in which the feedback information transmitted for the n-1th first resource is located.

[0038] In one embodiment, the first terminal turns on a first timer after receiving the n-1th first resource, and sets the time length of the first timer to a first time length A slots. Correspondingly, the second terminal cannot select resources within A slots after the n-1th first resource when performing resource selection or re-selection.

[0039] The first time length may be equal to or less than the length between the n-1th first resource and the nth first resource. If the time length of the first timer exceeds the first time length, a second timer may be turned on, and the time length of the second timer may be set to a second time length, which is the length of the nth first resource. Correspondingly, at this time, the resource selected or reselected by the second terminal must be within the nth first resource.

[0040] When the first time length is smaller than the length between the n-1th first resource and the nth first resource, the second time length may be larger than the length of the nth first resource, specifically, the nth first resource plus the previous B slots. Correspondingly, at this time, the resource selected or reselected by the second terminal must be within the total length of the nth first resource plus the previous B slots.

[0041] In another embodiment, the first terminal may turn on the first timer after a first number of symbols or slots have elapsed since receiving the n-1th first resource, for example, turning on the first timer after C slots, and the first time length is D slots. Correspondingly, at this time, the second terminal cannot select a resource within the D slots when performing resource selection or reselection. The second timer also turns on after the first timer times out, and has a length of the nth first resource plus the following C slots. Correspondingly, at this time, the resource selected or reselected by the second terminal must be within the length of the nth first resource plus the following C slots.

[0042] When the second time length is the total length of the nth first resource plus the B slots before it and the C slots after it, correspondingly, the resource selected or reselected by the second terminal at this time must be within the total length of the nth first resource plus the B slots before it and the C slots after it.

[0043] In another embodiment, the first terminal may turn on a first timer after the resource in which the feedback information is transmitted for the n-1th first resource is located, and the first time length is the length between the resource in which the feedback channel is located and the nth first resource. After the first timer times out, the second timer may be turned on, and the length of the second timer may be the length of the nth first resource. Correspondingly, at this time, the resource selected or reselected by the second terminal must be within the nth first resource.

[0044] When the first time length is smaller than the length between the feedback channel location resource and the n-th first resource, the second time length may be larger than the length of the n-th first resource, specifically, the length of the n-th first resource plus the previous B slots. Correspondingly, at this time, the resource selected or reselected by the second terminal must be within the total length of the n-th first resource plus the previous B slots.

[0045] In another embodiment, the first terminal may turn on a first timer after a second number of symbols or slots have elapsed after the resource in which the feedback information transmitted for the n-th first resource is located, for example, turning on the first timer after E slots, and the first time length is F slots. Correspondingly, at this time, the second terminal cannot select a resource within the F slots when performing resource selection or reselection. The second timer is also turned on after the first timer times out, and has a length of the n-th first resource plus the following E slots. Correspondingly, at this time, the resource selected or reselected by the second terminal must be within the length of the n-th first resource plus the following E slots.

[0046] When the second time length is the total length of the nth first resource plus the B slots before it and the C slots after it, correspondingly, the resource selected or reselected by the second terminal must be within the total length of the nth first resource plus the B slots before it and the C slots after it.

[0047] Furthermore, when the second timer is running, if the first terminal receives another SCI that includes a reservation chain, i.e., indicates a new first resource, the first terminal turns off the second timer and performs DRX using the new first resource.

[0048] Furthermore, when the second timer is turned on, the method includes: The method further includes a step of changing the time length of the second timer from the second time length to a third time length when it is found that the mth first resource is occupied or needs to be re-evaluated due to pre-emption or re-evaluation, or running the second timer until new control signaling and / or data is received, wherein the mth first resource is the nth first resource or a first resource after the nth first resource.

[0049] Here, the first terminal may know that it is occupied by, specifically, not being able to receive any PSCCH / PSSCH transmission, or by receiving a PSCCH / PSSCH transmission from another UE, or by failing to demodulate the PSCCH / PSSCH, etc.

[0050] In one embodiment, when the first terminal turns on the second timer before or after the nth first resource, if it finds that the nth first resource is occupied for pre-emption or re-evaluation or needs to be re-evaluated, it may change the second length of the second timer from the second length of X slots to a third length of Y slots, or operate the second timer until new control signaling and / or data is received, and may further perform DRX using the new control signaling and / or data. Here, when changing the time length of the second timer from the second length of time to the third length of time, it is required that the new control signaling and / or data is within the range of the third length of time.

[0051] In another embodiment, when the first terminal determines that the n-1th first resource or the nTth first resource has occupied the n, n+1...th first resource for pre-emption or re-evaluation or needs to be re-evaluated, and the nTth first resource is located T time before the nth first resource, the UE does not turn on the first timer, or immediately turns on the second timer, and sets the second time length to Y slots, or operates the second timer until new control signaling and / or data is received, and further performs DRX with the new control signaling and / or data. When changing the time length of the second timer from the second time length to the third time length, the new control signaling and / or data is required to be within the range of the third time length. The T may be a value defined by a protocol, configured by a base station, or configured by the second terminal.

[0052] Correspondingly, the second terminal may perform resource selection or reselection based on first configuration information for discontinuous reception and / or resources in which the received feedback information is located, and the first configuration information includes configuration information for a timer, which is for instructing the first terminal whether or not it needs to monitor control signaling and / or data from the second terminal.

[0053] Furthermore, when the first configuration information includes configuration information of a first timer and / or configuration information of a second timer, a location of a second resource, which is a corresponding transmission resource when the first timer of the first terminal is operated, is determined based on a resource in which the first timer and / or feedback information is located. A specific manner of determining the location of the second resource is as follows.

[0054] When the first configuration information includes the configuration information of the first timer, for example, the position of the resource where the feedback information is located is in slot A, and the number of slots corresponding to the first time length in the configuration information of the first timer is X. The first time length may be converted to the number of slots by ms, or may be directly configured to the number of slots, and thus, among the X slots after slot A, the second terminal does not select these slots as selectable transmission resources, that is, the transmission resources corresponding to these slots are the second resources. Here, the X slots may be physical slots or logical slots. The logical slots may further refer to all slots available for sidelink and slots belonging to a sidelink resource pool.

[0055] When the second terminal performs resource selection or reselection, the second terminal excludes the obtained second resource location from the selectable transmission resource of the second terminal. The above-mentioned transmission resource exclusion may specifically use the following two methods: 1. When the physical layer reports available resources, it will exclude inappropriate resources before reporting them to the medium access control (MAC) layer, and the MAC layer will randomly select among them. At this time, the MAC layer needs to determine the second resource of the second terminal corresponding to the operation of the Drx-HARQ-RTT-TimerSL of the first terminal, and then notify the physical layer. When selecting candidate resources, the physical layer excludes the second resource, and reports available resources to the MAC layer, and then the MAC layer finally selects the transmission resource. 2. Another way is that after the physical layer announces the candidate resources, the MAC layer directly eliminates the inappropriate resources and then randomly selects them. If there are insufficient resources to select after the MAC layer eliminates them, it will trigger resource re-election.

[0056] Furthermore, when the second terminal selects or reselects a resource, it does not need to exclude the second resource first, and thus discards the selected or reselected transmission resource or triggers the reselection process when the selected or reselected transmission resource belongs to the second resource.

[0057] Thus, an embodiment of the present application provides a discontinuous reception method, and by performing discontinuous reception based on a sidelink based on the first timer, the first terminal can accurately receive control signaling and / or data transmitted from the second terminal.

[0058] FIG. 5 shows another flowchart of the discontinuous receiving method provided in the embodiment of the present application. As shown in FIG. 5, the embodiment of the present application does not define a first timer, and the method may include the following step S501.

[0059] In step S501, when the first configuration information includes configuration information of a second timer, discontinuous reception based on a side link is performed based on the second timer, and the second timer is for instructing the first terminal that it is necessary to monitor control signaling and / or data from the second terminal during the second timer operation period.

[0060] Furthermore, in step S501, The method includes a step of performing discontinuous reception based on a side link based on the second timer when the first configuration information includes configuration information of a second timer, the second timer being for instructing the first terminal that it is necessary to monitor control signaling and / or data from the second terminal during an operation period of the second timer.

[0061] Furthermore, the step of performing discontinuous reception based on a side link based on the second timer includes: turning on a second timer for each first resource, the second timer having a second duration of: The length of the first resource; Deployment by base station, Placement by protocol, The second terminal is determined by at least one of the configurations.

[0062] Furthermore, when turning on the second timer, the method includes: The method further includes a step of turning on a second timer and setting the time length of the second timer to a third time length when the priority or re-evaluation determines that the mth first resource is occupied, or running the second timer until new control signaling and / or data is received, wherein the mth first resource is the nth first resource or a first resource after the nth first resource.

[0063] In one embodiment, when the first terminal finds that the nth first resource is occupied for pre-emption or re-evaluation or requires re-evaluation, the first terminal immediately turns on a second timer, sets the second time length to X slots, or operates the second timer until new control signaling and / or data is received, and further performs DRX based on the new control signaling and / or data.

[0064] Correspondingly, at this time, when the second terminal performs resource selection or reselection, it cannot select a resource between the n-1th first resource and the nth first resource, which can be realized by setting the T1 length before the resource selection window. As shown in Figure 6, by setting the T1 length, the reselected resource of the second terminal is located within the resource selection window, for example, reselected resource #2.

[0065] If the second time length of the second timer is set to X slots, the resource selected or reselected by the second terminal is required to be within X slots.

[0066] In another embodiment, when the first terminal finds out at the (n-1)th first resource or the (nT)th first resource that the (n), (n+1)th ... first resource is occupied for pre-emption or re-evaluation or needs to be re-evaluated, the first terminal immediately turns on a retransmission timer, sets the second time length to X slots, or operates the second timer until new control signaling and / or data is received, and further performs DRX based on new resource reservation information.

[0067] Correspondingly, when the second terminal selects or reselects a resource, it cannot select a resource between the n-1th first resource and the nth first resource, which can be realized by setting the T1 length before the resource selection window. If the second time length of the second timer is set to X slots, the resource selected or reselected by the second terminal is required to be within X slots.

[0068] Thus, an embodiment of the present application provides a discontinuous reception method, and by performing discontinuous reception based on a sidelink based on the second timer, the first terminal can accurately receive control signaling and / or data transmitted from the second terminal.

[0069] FIG. 7 shows another flowchart of the discontinuous reception method provided in an embodiment of the present application. As shown in FIG. 7, in an embodiment of the present application, the first terminal does not perform timer-based DRX, and the method may include the following step S701.

[0070] In step S701, when there is no configuration information of the first timer, discontinuous reception based on the sidelink is performed for the second terminal based on the first resource location.

[0071] Furthermore, in step S701, monitoring at an n-th first resource location for control signaling and / or data from a second terminal; and not needing to monitor control signaling and / or data from the second terminal at any location other than the first resource location.

[0072] Furthermore, the method comprises: If the priority or re-evaluation determines that the mth first resource is occupied, the method further includes monitoring the control signaling and / or data for a fourth length of time or until new control signaling and / or data is received, the mth first resource being the nth first resource or a first resource after the nth first resource.

[0073] In one embodiment, when the first terminal finds that the n-th first resource is occupied for pre-emption or re-evaluation or needs to be re-evaluated, the UE enters a DRX active time, i.e. starts monitoring the channel for control signaling and / or data, for a length of M slots or until new control information and / or data is received, and performs further DRX with the control information and / or data.

[0074] Correspondingly, when the second terminal performs resource re-selection, it cannot select a corresponding resource between the n-1th first resource and the nth first resource, which can be specifically realized by setting the T1 length before the resource selection window. If the length of monitoring the control signaling and / or data in the channel is set to the fourth time length M slots, the resource re-selected by the second terminal must be within the M slots. For example, the distance between any two selected resources of the second terminal may be smaller than M, including re-selection or packet loss triggered by at least one of preemption, prioritization, congestion control, etc.

[0075] In another embodiment, when the first terminal finds out in the n-1th first resource that the n, n+1...th first resources are occupied for pre-emption or re-evaluation or require re-evaluation, the first terminal transitions to a DRX active time, sets the length to K slots, or monitors until new control information and / or data is received, and further performs DRX with the new control information and / or data.

[0076] Correspondingly, at this time, the second terminal can select a resource between the n-1th first resource and the nth first resource. If the length of monitoring the control signaling and / or data in the channel is set to K slots, the resource reselected by the second terminal must be within the K slots.
