Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

The present disclosure proposes a control method of semi-persistent scheduling, which is described below with reference to fig. 1 to 3.

Fig. 1 is a flow chart of some embodiments of a control method of semi-persistent scheduling of the present disclosure. As shown in fig. 1, the method of this embodiment includes: steps S102 to S104.

In step S102, the base station sends a signaling to the terminal, and correspondingly, the terminal receives the signaling sent by the base station, where the signaling carries SPS DRX (Discontinuous Reception ) configuration information, where the SPS DRX configuration information is used to instruct the terminal to not receive one or more SPS PDSCH (Physical Downlink Shared Channel ) corresponding to SPS configuration during a DRX sleep period and/or inactive time when the terminal turns on DRX.

In the existing standard, each terminal can support at most two sets of DRX configuration information, and each set of DRX configuration information can contain different on Duration, long period and other parameters, but only one set of DRX configuration information is used. The DRX configuration information may include on Duration (DRX wake-up time), DRX Cycle (inactivity timer), retransmission timer (retransmission timer), active-time, etc. parameters. The definition of the individual parameters is briefly described below.

on Duration: the terminal maintains awake time after each wake-up from DRX, and monitors PDCCH (Physical Downlink Control Channel ) during this time.

DRX Cycle: consists of a DRX wake-up time and a DRX sleep time (Opportunity for DRX) and is repeated periodically, as shown in fig. 2.

The inactivity-timer: the terminal keeps awake duration after successfully demodulating the PDCCH; if the PDCCH demodulation fails, returning to the sleep state according to the original sleep time.

retransmission-timer: for receiving the duration of the retransmission.

active-time: the total Duration of the terminal listening to the PDCCH may include the time of "on Duration" of the DRX cycle, the time of "inactivity-timer" and the time of "retransmission-timer".

The DRX inactivity time refers to a time outside the active-time in the DRX cycle, where the base station configures SPS DRX configuration information for the terminal, and is configured to instruct the terminal to not receive one or more SPS PDSCH corresponding to SPS configuration in the DRX sleep period and/or inactivity time according to the DRX related parameter. I.e., after DRX is turned on for the terminal, DRX is applied to SPS PDSCH corresponding to one or more SPS configurations in addition to PDCCH.

One or more SPS configurations may be configured and activated simultaneously for each terminal, e.g., the following parameters may be configured for each SPS, and activation and deactivation of one or more SPS configurations may be performed through DCI (Downlink Control Information ):

cs-RNTI: configuring a scheduling radio network temporary identity for activation/deactivation and retransmission

nrofHARQ-Processes: SPS HARQ process number

harq-procad-Offset: offset value of SPS HARQ process ID

Perioconductivity: SPS period

Further, the SPS DRX may be configured on some or all of the one or more SPS configurations that are active, i.e., the terminal does not receive SPS PDSCH corresponding to the SPS configuration of the SPS DRX during DRX sleep periods and/or inactivity times when the terminal is on DRX, and/or the terminal receives SPS PDSCH corresponding to the SPS configuration of the SPS DRX during DRX wake-up times and/or activity times. For example: when the energy saving requirement of the terminal is high, SPS configuration of the service with low requirement on the transmission part time delay is started, SPS DRX is not started when SPS configuration of the service with high requirement on the transmission time delay is started, namely SPS PDSCH reception is still carried out in the DRX dormant period.

In some embodiments, the signaling carrying SPS DRX configuration information includes: RRC (Radio Resource Control ) signaling, MAC (Medium Access Control, medium access control signaling) and DCI (downlink control information).

SPS DRX configuration information may be configured by at least one of: adding SPS DRX configuration information in SPS configuration and/or DRX configuration of at least one signaling in the existing RRC, MAC CE and DCI; and adding at least one signaling of RRC, MAC CE and DCI for carrying SPS DRX configuration information.

In some embodiments, where the signaling includes RRC signaling, SPS DRX configuration information is included in the DRX configuration of the RRC signaling; and/or including SPS DRX configuration information in one or more SPS configurations of RRC signaling; and/or, the predefined cell contains SPS DRX configuration information in RRC signaling.

SPS DRX configuration information may be included in existing DRX configurations and/or SPS configurations in RRC signaling, or may be included in predefined cells carried by RRC signaling. For example, SPS DRX configuration information is included in the DRX-Config and/or DRX-ConfigSecondaryGroup of RRC signaling. For another example, SPS DRX configuration information is included in SPS-Config of RRC signaling. For another example, SPS DRX configuration information is carried in the RRC signaling predefined cell DRX-SPSConfig.

In some embodiments, in the case where SPS DRX configuration information is included in the DRX configuration of RRC signaling, the indication information includes: indication information for indicating whether one or more SPS configurations are SPS DRX on, and/or an identification of one or more SPS configurations that are SPS DRX on. For example, the indication information includes: the DRX-SPSFlag is used to indicate whether SPS DRX is on, and the DRX-SPSConfigIndex is used to indicate the sequence number or sequence number set of SPS configuration of SPSDRX. If SPS DRX is enabled, but does not include identification of one or more SPS configurations of the enabled SPS DRX, SPS DRX may be enabled by default for all SPS configurations.

In some embodiments, where SPS DRX configuration information is included in one or more SPS configurations of RRC signaling, the indication information includes: indication information for indicating whether one or more SPS configurations are SPS DRX enabled, and/or one or more SPS configuration are SPS DRX enabled timers. The timer of SPS DRX is used to indicate the time when reception of the corresponding SPS PDSCH is affected by DRX.

For example, the indication information includes: the DRX-ActivateFlag indicates indication information of whether SPS DRX is turned on; the DRX-ActivateTimer represents the timer for SPS DRX. In RRC signaling, SPS DRX configuration information may be added in each of one or more SPS configurations of the SPS DRX that are enabled, the added SPS DRX configuration information in each SPS configuration including indication information to indicate whether the SPS configuration is enabled for SPS DRX and/or a timer for the SPS configuration to enable SPS DRX. The SPS DRX configuration information added in each of the one or more SPS configurations of the on SPS DRX may be the same or may only be added at a certain SPS configuration, including: indication information of whether SPS DRX is turned on, an identification of SPS configuration of SPS DRX is turned on and/or a timer of SPS configuration of SPS DRX is turned on.

In some embodiments, the SPS DRX configuration information further comprises: and enabling a sleep instruction corresponding to part or all of one or more SPS configurations of SPS DRX. In the case where the signaling includes MAC signaling, the sleep instruction is contained in a MAC CE (Control Element) or a DRX Command (Command). For example, the sleep instruction is to instruct some or all of the one or more SPS configurations of the SPS DRX to immediately enter a sleep period and/or cease reception of the corresponding SPS PDSCH.

For example, predefining or reusing existing fields in an existing MAC CE or DRX Command contains sleep instructions, such as: setting LCID to a preset value (e.g., 01100) represents a sleep instruction. As another example, the predefined SPS DRX Command MAC CE includes a sleep instruction. The SPS DRX configuration information may also include an identification of a partial SPS configuration of the one or more SPS configurations for the on SPS DRX if the sleep instruction is set for the partial SPS configuration.

In some embodiments, in the case where the signaling includes DCI, SPS DRX configuration information is included in DCI activation signaling corresponding to one or more SPS configurations. For example, predefining a dedicated field or reusing an existing DCI field in existing DCI activation signaling corresponding to one or more SPS configurations includes SPS DRX configuration information, e.g.: one or more fields of existing HARQ process number (hybrid automatic repeat request process number), RV (redundancy version), MCS (modulation and coding strategy), FDRA (frequency domain resource allocation) are utilized.

The DRX mechanism can enable the terminal to wake up and sleep periodically, and can flexibly prolong the time of the terminal for monitoring the PDCCH if necessary, so that the service delay is reduced, but the technology still has a space for further optimization. Because in the actual application scenario, the terminal will not continuously send or receive data, for example, when the user is reading the cached web page with the mobile phone, interaction with the network is not needed, and if the terminal is still periodically awakened, unnecessary power consumption is additionally caused. Therefore, based on the original DRX mechanism, in order to optimize the power consumption of the terminal, 3GPP proposes a DRX Adaptation, also called DCP WUS (Wake-Up Signal), in 5g Release 16, when the network side needs to perform uplink and downlink scheduling for a certain terminal, a WUS Signal (PDCCH carrying DCI Format 2_6) is sent to the terminal, the terminal detects the WUS Signal in a time window before the DRX wakeup phase, when the terminal receives the WUS Signal, detects the PDCCH in the DRX wakeup phase, and if no WUS Signal is detected in the time window, the terminal maintains a sleep state in the subsequent DRX wakeup phase, and does not perform PDCCH detection, so as to reduce the power consumption, thereby improving the battery service time.

It should be noted that if the network side indicates that the service of the DRX on-duration that needs to be closed does not match with the service of the terminal through WUS, the transmission of the service of the terminal may be affected. If the WUS is only associated with the short DRX and the period of the short DRX is configured to be relatively short, if the WUS is not received, that is, the terminal is required to enter sleep at the short DRX, the terminal may not enter sleep state yet, which results in not realizing a better energy saving effect. Therefore, WUS generally only works for long DRX when both are configured.

It should be noted that, the WUS related configuration parameter is that the network side device sends the DCP-Config-r16 carried by RRC Setup or RRC Reconfiguration to the terminal, the PS-RNTI is an RNTI newly added in 5g Release 16, which is fully called Power save-RNTI (Power save radio network temporary identity) for performing CRC scrambling on the PDCCH sent to the terminal, and it should be noted that the terminal only monitors the PDCCH scrambled by the PS-RNTI in the sleep state.

As shown in fig. 3, by semi-static configuration of PS-offset, DCP monitoring is started at the position of PS-offset before DRX on-duration, when it is monitored that DCP contains WUS, PDCCH is detected at the next DRX on-duration, otherwise PDCCH detection is not performed at the next DRX on-duration.

In some embodiments, the SPS DRX configuration information further comprises: SPS DCP configuration information for indicating whether a DCP (DCI with CRC scrambled by PS-RNTI, downlink control information using power save radio network temporary identity scrambling) configuration is on for some or all of one or more SPS configurations of an on SPS DRX. The DCP scheme can be applied to SPS by adding new SPS DCP configuration information to further reduce the energy consumption of SPS transmissions.

In some embodiments, the SPS DRX configuration information further comprises: indication information for indicating that some or all of one or more SPS configurations of the SPS DRX on stop or suspend or resume reception of SPS PDSCH.

In step S104, the terminal receives SPS PDSCH according to the SPS DRX configuration information.

In some embodiments, the terminal does not receive SPS PDSCH corresponding to one or more SPS configurations during DRX sleep period and/or inactive time according to SPS DRX configuration information, and receives SPS PDSCH corresponding to one or more SPS configurations during DRX wake-up time and/or active time.

In some embodiments, the SPS DRX configuration information includes: and under the condition that a dormancy instruction corresponding to part or all of one or more SPS configurations of the SPS DRX is turned on, the terminal immediately enters a dormancy period and/or stops the reception of a corresponding SPS PDSCH for the one or more SPS configurations according to the dormancy instruction under the condition that the dormancy instruction is received.

In some embodiments, in the case where the SPS DRX configuration information includes SPS DCP configuration information, the terminal performs at least one of the following operations according to the SPS DCP configuration information: detecting a DCP wake-up signal WUS in a DRX sleep period under the condition of starting a DCP configuration; receiving an SPS PDSCH corresponding to SPS configuration of the DCP configuration in the next DRX wake-up period under the condition that the DCP configuration is turned on and the DCP WUS is detected; in the case of starting the DCP configuration and detecting no DCP WUS, not receiving SPS PDSCH corresponding to SPS configuration of the starting DCP configuration in the next DRX wake-up period; receiving one or more SPS PDSCH corresponding to SPS configuration in the next DRX wake-up period under the condition that the DCP configuration is not turned on and the DCP WUS is detected; in the case where the DCP configuration is not turned on and the DCP WUS is not detected, one or more SPS PDSCH corresponding to the SPS configuration is received in the next DRX wake-up period.

In some embodiments, a terminal sets an SPS DRX state for all or part of one or more SPS configurations of an on SPS DRX, wherein the SPS DRX state comprises: the active state and/or the inactive state, or the SPS DRX state includes: an on state and/or an off state. Further, the terminal does not receive the corresponding SPS PDSCH in the DRX dormant period and/or the inactive time aiming at SPS configuration of which SPS DRX is in an active state or an on state; and/or, for SPS configuration in which SPS DRX is in a deactivated state or an off state, receiving a corresponding SPS PDSCH during a DRX sleep period and/or inactive time.

In some embodiments, the terminal transmits terminal assistance information (UE Assistance Information) to the base station, wherein the terminal assistance information comprises: indication of one or more SPS configurations of the SPS DRX recommended by the terminal, wherein the SPS DRX is turned on for the SPS configuration, which means that, when the DRX is turned on, SPS PDSCH corresponding to the one or more SPS configurations of the SPS DRX is not received during a DRX sleep period and/or inactive time. The base station may generate signaling carrying SPS DRX configuration information according to the terminal assistance information.

For example, adding the corresponding recommended cell of the SPS DRX configuration cell in the DRX-reference or DRX-Preference config cell, for example: the preferredDRX-SPS-ConfigIndex indicates the identity of the SPS configuration recommended for on DRX. And the terminal sends terminal auxiliary information according to the XR service characteristics, recommends SPS DRX parameter configuration to the network, and can better meet service requirements.

According to the method, the existing or newly added RRC, MAC CE and DCI signaling is used for configuring SPS to perform discontinuous reception in the DRX dormant period, the downlink reception of SPS PDSCH can be further energy-saving based on the existing DRX mechanism, the method is suitable for novel services/terminals, and the energy consumption is remarkably reduced. Various modes of SPS DRX configuration based on the existing SPS configuration or DRX configuration are supported, the configuration modes are flexible, and extra signaling load is remarkably reduced. The single SPS/partial SPS/all SPS discontinuous reception can be carried out according to service requirements and network conditions, recommended configuration can be sent to a network, and collaborative optimization of network service is realized. The SPS DRX configuration is activated/deactivated in a single/partial/full mode, the SPS PDSCH transmission is stopped/suspended/resumed in a mode of supporting, semi-static/dynamic adjustment of SPS discontinuous transmission is achieved, and service requirements and network changes are better adapted.
