Abstract
Description
Technical Field
[0001] Embodiments of the present invention relate to the field of communication technologies.
Background Art
[0002] As an important component of the world's new infrastructure construction, the 5G (5th Generation Mobile Communication Technology) communication network has achieved rapid development worldwide in recent years. As the scale of the network grows, the energy consumption of communication operators continues to increase. Taking the data released by the Ministry of Industry and Information Technology of China as an example, in 2022, compared with 2015, the growth rate of energy consumption reached about 80%.
[0003] With the construction of 5G and the large-scale commercialization of 5G Active Antenna Unit (AAU), due to the high power consumption of AAU, its energy consumption doubles compared with the Remote Radio Unit (RRU) mainly used in 3G and 4G. 5G defines three types of service types: Enhanced Mobile Broadband (eMBB), massive Machine Type of Communication (mMTC), and Ultra Reliable Low Latency Communication (URLLC). Therefore, the bursty services of 5G packets continue to increase, the base station operates 24 hours without rest, and the average daily energy consumption of 5G sites has become more than twice that of 4G.
[0004] The 3GPP (registered trademark) (3rd Generation Partnership Project) introduced key technologies such as Massive MIMO and wider radio frequency bands in the 5G era. 5G supports higher data rates and greater data traffic, requiring more transmission bandwidth, and the deployment of high-frequency bands will be the main frequency band to expand in the future. However, the transmission characteristics of high-frequency bands limit the communication range of sites, leading to concentrated deployment of 5G sites and increased power consumption, placing significant operational cost pressure on operators. Therefore, network energy conservation is of crucial importance for saving operational costs, and 5G network energy conservation is an issue that needs to be addressed urgently.
[0005] To achieve energy savings, network devices can perform energy-saving processes in the time domain, frequency domain, spatial domain, and / or energy domain, respectively, based on the network load. For example, in the spatial and energy domains, network devices can achieve energy savings by turning off some antennas when the load is low, and in the time domain, network devices may implement cell-level discontinuous transmission / reception techniques so that the network device does not transmit and / or receive signals during certain periods of inactivity, in order to achieve energy savings.
[0006] Furthermore, the above explanation of the background art is merely intended to provide a clearer and more complete explanation of the present invention and to facilitate understanding for those skilled in the art. These elements, as described in the background art section of the present invention, should not be construed as being well-known to those skilled in the art. [Overview of the project] [Problems that the invention aims to solve]
[0007] According to the inventors' findings of the present invention, in the case of user equipment (UEs) in connected mode, it is considered that at least the following candidate channels / signals will not be transmitted / received during the deactivation stage of cell discontinuous transmitting / receiving (DTX / DRX).
[0008] Downlink: Periodic / semi-sustained CSI-RS (Channel State Information-Reference Signal) (including TRS (Tracking RS)), PRS (Positioning Reference Signal) PDCCH (Physical Downlink Control Channel) scrambled with UE-specific RNTI (Radio Network Temporary Identity), Type-3 CSS (Common search space) PDCCH SPS PDCCH (Semi-static scheduled PDCCH) Uplink: SR (Scheduling Request) Periodic / semi-persistent CSI (Channel State Information) report. Periodic / semi-sustained SRS (Sounding Reference Signal) CG (Configured Grant) - PUSCH (Physical Uplink Shared Channel).
[0009] In other words, in connected mode UEs, the UE does not send SRs during the cell DTX / DRX inactive phase. This disrupts processes that need to trigger SRs to request uplink resources and the transmission of triggered pending SRs, causing problems.
[0010] In view of the above problems, the embodiments of the present invention provide a communication method and apparatus for a cell non-continuous transmission / reception scenario. [Means for solving the problem]
[0011] One embodiment of the present invention provides a communication device configured in a terminal device, which includes a processing unit that, when the network is in network energy-saving mode, does not trigger scheduling requests and / or performs operations related to network energy-saving mode for pending scheduling requests (SRs).
[0012] In some embodiments, the network energy saving mode means at least one of the following: the network energy saving mode is activated; cell DTX / DRX is configured and / or activated; and the UE is in an inactive state of cell DTX / DRX.
[0013] In some embodiments, the scheduling request includes at least one of the following: a buffer status report (BSR) scheduling request, a beam fault recovery (BFR) scheduling request, a consistent listen-before-talk failure recovery (consistent LBT failure recovery) scheduling request, a scheduling request related to access backhaul integration (IAB), a scheduling request related to positioning, and a scheduling request related to non-terrestrial networks (NTN).
[0014] In some embodiments, the operations associated with the network energy-saving mode include canceling pending scheduling requests (pending SRs), assuming there are no valid PUCCH resources configured for pending SRs, assuming SR transmissions are low-priority SR transmissions, pending SR counters, not initiating random access procedures, not performing clearing and / or release operations, and using a maximum number of greater SR transmissions (sr-TransMax).
[0015] Another embodiment of the present invention provides a communication device configured in a network device, which includes a first instruction unit that instructs a terminal device on information related to network energy saving.
[0016] One of the advantageous effects of the embodiments of the present invention is as follows: According to the embodiments of the present invention, when the network is in network energy saving mode, the terminal device does not trigger the SR, thereby preventing the pending SR from triggering the random access procedure and reducing the network's energy consumption. Furthermore, when the network is in network energy saving mode, the terminal device performs an action related to network energy saving mode on the pending SR, thereby preventing the pending SR from releasing the uplink configuration to the terminal.

[0036] In the following explanation, "if..." may be replaced with "if..." or "when..." as long as it does not cause confusion.
[0037] In embodiments of the present invention, a scheduling request is used to request UL-SCH (Uplink Shared Channel) resources for a new transmission.
[0038] A MAC (Media Access Control) entity can be configured to have zero, one, or more SR configurations. An SR configuration consists of a set of PUCCH (Physical Uplink Control Channel) resources for SR across different BWPs (Bandwidth Parts) and cells. For logical channel or SCell (Secondary Cell) beam fault recovery and persistent LBT (Listen Before Talk) fault recovery, each BWP configures up to one PUCCH resource for SR. For logical channels serving radio bearers configured with SDT (Small Data Transfer), no PUCCH resources for SR are configured for SDT. For beam fault recovery of the serving cell's BFD-RS (Beam Failure Detection-Reference Signal) set, each BWP configuration configures up to two PUCCH resources for SR. A dedicated SR configuration is configured for positioning gap activation / deactivation requests.
[0039] Each SR configuration corresponds to one or more logical channels and / or SCell beam fault recovery and / or persistent LBT fault recovery and / or BFD-RS set beam fault recovery and / or positioning gap activation / deactivation requests. Each logical channel, SCell beam fault recovery, BFD-RS set beam fault recovery and persistent LBT fault recovery can be mapped to zero or one SR configuration configured by RRC (Radio Resource Control). The SR configuration of a logical channel that triggers a BSR (Buffer Status Report), or SCell beam fault recovery or BFD-RS beam fault recovery set or persistent LBT fault recovery (if such a configuration exists) or positioning gap activation / deactivation request is considered the corresponding SR configuration for the triggered SR. Any SR configuration can be used for SRs triggered by Pre-emptive BSR or Timing Advance Report.
[0040] RRC configures the following parameters for the scheduling request procedure.
[0041] • sr-ProhibitTimer (each SR configuration) ·sr-TransMax (each SR configuration).
[0042] The scheduling request procedure uses the following UE variables:
[0043] ·SR_COUNTER (each SR configuration).
[0044] If an SR is triggered and no other SRs in the same SR configuration are pending, the MAC entity should set the SR_COUNTER of the corresponding SR configuration to 0.
[0045] When an SR (Special Reaction) is triggered, it should be considered pending until the SR is canceled.
[0046] Before a MAC PDU (Protocol Data Unit) is assembled, all pending SRs of a BSR triggered according to the BSR procedure must be canceled, and when the MAC PDU is transmitted, each corresponding sr-ProhibitTimer (SR disable timer) must be stopped, and the PDU contains a long or short BSR MAC CE (Control Element) that triggers the last event of the BSR before the MAC PDU is assembled (contained). If the UL (Uplink, abbreviated as "Uplink") grant can accommodate all pending data available for transmission, all pending SRs of a BSR triggered according to the BSR procedure should be canceled, and each corresponding sr-ProhibitTimer should be stopped.
[0047] For each pending SR that has not been triggered according to the serving cell's BSR procedure, the MAC entity performs the following actions:
[0048] 1> If the SR is triggered by a Pre-emptive BSR procedure before the MAC PDU is assembled, and the MAC PDU containing the associated Pre-emptive BSR-MAC CE is sent, 1> If the SR is triggered by beam failure recovery of the SCell, a MAC PDU is transmitted, the PDU includes a MAC CE for BFR (Beam Failure Recovery), and the MAC CE includes beam failure recovery information for the SCell, or 1> If the SR is triggered by beam fault recovery of the serving cell's BFD-RS set, a MAC PDU is transmitted, and the PDU includes an extended BFR MAC CE or a truncated extended BFR MAC CE, and the BFR MAC CE includes beam fault recovery information of the serving cell's BFD-RS set, or 1> The SR is triggered by beam fault recovery of the SCell set, and the SCell is deactivated, or 1> The SR is triggered by beam fault recovery of the BFD-RS set of the SCell set, and the SCell is deactivated, or 1>SR is triggered by a positioning gap activation / deactivation request, and the positioning gap activation / deactivation request MAC CE that triggered the SR is canceled, or 1> If the SR is triggered by the recovery of a persistent LBT fault in the SCell, a MAC PDU is transmitted, and the MAC PDU includes an LBT fault MAC CE indicating a persistent LBT fault in the SCell, 1> The SR is triggered by the recovery of a persistent LBT fault in the SCell, and all triggered persistent LBT faults in the SCell are canceled, or 1> If the SR is triggered by a timing advance report and all triggered timing advance reports are canceled, 2> Cancel any pending SRs, and if any are running, stop the corresponding sr-ProhibitTimer.
[0049] Only PUCCH resources on BWP that are in an activated state during the SR transmission opportunity are considered valid.
[0050] As long as one or more SRs are pending, the MAC entity performs the following actions for each pending SR:
[0051] 1> If the MAC entity does not have a valid PUCCH resource configured for a pending SR, 2> Start a random access procedure with SpCell (Special Cell) and cancel any pending SRs.
[0052] 1> Otherwise, regarding the SR configuration of the corresponding pending SR, 2> If a MAC entity has an SR transmission opportunity with a valid PUCCH resource configured for SR, 2> If sr-ProhibitTimer is not operating during the SR transmission opportunity, 2> If the PUCCH resources used for SR transmission opportunities do not overlap with the measurement gap, 3> If the PUCCH resources used for SR transmission opportunities do not overlap with UL-SCH (Uplink Shared Channel) resources (UL-SCH resources that are not permitted to be transmitted simultaneously with SR in configurations such as simultaneousPUCCH-PUSCH, simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup, or simultaneousSR-PUSCH-diffPUCCH-Groups) and do not overlap with SL-SCH (Sidelink Shared Channel) resources, 3> If the MAC entity can perform SR transmission simultaneously with the transmission of SL-SCH resources, 3> For MAC entities, ich-based prioritization is configured, and the PUCCH resource used for SR transmission opportunities does not overlap with the PUSCH duration of uplink grants received in random access responses, or does not overlap with the PUSCH duration of uplink grants addressed to temporary C-RNTI (Cell Radio Network Temporary Identifier), or MSGA (message A. The PUSCH duration of the message A) payload does not overlap with the PUSCH duration, and the PUCCH resource for the SR transmission opportunity of the pending SR being triggered overlaps with any other UL-SCH resource, and the physical layer can transmit a (single) SR on a PUCCH resource that is valid for the SR, and the priority of the logical channel triggering the SR is higher than the priority of the uplink grant of any UL-SCH resource, where the uplink grant has not yet been de-prioritized, simultaneous transmission with the SR is not permitted by the configuration of simultaneousPUCCH-PUSCH, simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup, or simultaneousSR-PUSCH-diffPUCCHgroups, and the priority of the uplink grant has been determined, or 3>When sl-PrioritizationThres and ul-PrioritizationThres are configured, the PUCCH resource for the SR transmission opportunity of the triggered pending SR overlaps with any UL-SCH resource carrying the MAC PDU, the determined priority value of the triggered SR is lower than sl-PrioritizationThres, the highest priority value of the logical channels in the MAC PDU is equal to or greater than ul-PrioritizationThres, and none of the prioritized MAC CEs are included in the MAC PDU, and the MAC PDU is not prioritized by the upper layer, or 3>Regarding the SR transmission opportunity of the triggered pending SR, if the SL-SCH resource overlaps with the PUCCH resource, the MAC entity cannot perform SR transmission simultaneously with the transmission of the SL-SCH source, the transmission of the SL-SCH resource is not prioritized, or the priority value of the logical channel for which the SR is triggered is lower than ul-PrioritizationThres (when configured), or 3>Regarding the SR transmission opportunity of the triggered pending SR, if the SL-SCH resource overlaps with the PUCCH resource, the MAC entity cannot perform SR transmission simultaneously with the transmission of the SL-SCH, and if the determined priority of the triggered SR for the SL-SCH resource is higher than the priority of the determined MAC PDU, 4>The SR transmission is considered a prioritized SR transmission.
[0053] 4>Except for the overlapping uplink grants permitted by the configurations of simultaneousPUCCH-PUSCH or simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup or simultaneousSR-PUSCH-diffPUCCH-Groups, other overlapping uplink grants (if any) are considered non-prioritized uplink grants.
[0054] 4>If the non-prioritized uplink grant is an uplink grant configured by autonomousTx (where PUSCH is activated), 5>Stop the configuredGrantTimer for each HARQ procedure of the non-prioritized uplink grant, 5>Stop the cg-RetransmissionTimer for each HARQ procedure of the non-prioritized uplink grant.
[0055] 4>If SR_COUNTER < sr-TransMax, 5> The physical layer signals (signal) to send the SR using one valid PUCCH resource for the SR, 5> If an LBT failure indication has not been received from a lower layer, 6>Increment SR_COUNTER by 1, 6>Start sr-ProhibitTimer.
[0056] 5> Otherwise, when lbt-FailureRecoveryConfig is not configured, 6>Increment SR_COUNTER by 1.
[0057] 4> Otherwise, 5> Notify RRC to release PUCCH for all serving cells, 5> Notify RRC to release SRS for all serving cells. 5> Clear all configured downlink assignments and uplink grants. 5> Clear all PUSCH resources for semi-sustaining CSI reports. 5> Start a random access procedure with SpCell and cancel all pending SRs.
[0058] 3> Otherwise, 4> The SR transmission is considered a non-priority SR transmission.
[0059] Note 1: When a MAC entity has multiple available PUCCH resources for SR transmission opportunities in addition to SR for SCell beam fault recovery, the UE is left to decide which of the available PUCCH resources for SR to select for transmitting signals to the SR.
[0060] Note 2: If multiple individual SRs trigger instructions from a MAC entity to the PHY layer to signal to the SR using the same valid PUCCH resource, the SR_COUNTER of the associated SR configuration will increment only once.
[0061] Note 3: If a MAC entity has pending SRs for SCell beam fault recovery, and the MAC entity has one or more PUCCH resources (in addition to the PUCCH resources for pending SRs for beam fault recovery in the BFD-RS set) that overlap with the PUCCH resources for SCell beam fault recovery in the SR transmission opportunity, the MAC entity will consider only the PUCCH resources for SCell beam fault recovery to be valid. If a MAC entity has pending SRs for beam fault recovery in the BFD-RS set of a serving cell, and the MAC entity has one or more PUCCH sources (in addition to the PUCCH resources for pending SRs for beam fault recovery) that overlap with the PUCCH resources for beam fault recovery in the BFD-RS set of the SR transmission opportunity, the MAC entity will determine that only the PUCCH resources for beam fault recovery in the BFD-RS set are valid.
[0062] Note 4: For UEs operating in semi-static channel access mode, PUCCH resources that overlap with a consecutive set of symbols that the UE will not transmit before the start of the next channel occupancy time are considered invalid.
[0063] Note 5: If the MAC entity consists of lch-based prioritization, the MAC entity does not consider UCI multiplexing when determining whether a valid PUCCH resource for SR transmission is signaled by the physical layer and whether the SR transmission opportunity overlaps with the PUCCH duration of the MSGA payload's uplink grant.
[0064] Note 6: If a MAC entity has a PUCCH resource for pending SR for SCell beam fault recovery that overlaps with a PUCCH resource for pending SR for BFD-RS set beam fault recovery for SR transmission opportunities, the UE implementation will select either the PUCCH resource for SCell beam fault recovery or the PUCCH resource for BFD-RS set beam fault recovery.
[0065] In the BSR procedure, the MAC entity performs the following actions:
[0066] 1> If the buffer status reporting process determines that at least one BSR has been triggered and not canceled, 2>If a UL-SCH resource is available for a new transmission and, as a result of logical channel priority, the UL-SCH resource can accommodate the BSR MAC CE and its subheader, 3>Instruct the multiplexing and assembly procedures to generate BSR MAC CE(s), 3> Unless all generated BSRs are long or short truncated, or extended long or short stage BSRs, start or restart the periodicBSR-Timer. 3> Start or restart retxBSR-Timer.
[0067] 2> If a normal BSR is triggered and logicalChannelSR-DelayTimer is not running, 3> If there are no UL-SCH resources available for the new transmission, or 3> For a logical channel where an uplink grant configured for a MAC entity is set and logicalChannelSR-Mask is set to false, if a normal BSR is triggered, 3> If the UL-SCH resources available for the new transmission do not meet the LCP (Logical Channel Prioritization) mapping limits set for the logical channel that triggers the BSR, 4> Trigger a scheduling request.
[0068] Note 2: If an uplink grant is configured, received, or determined for a MAC entity, the UL-SCH resource is considered available. If a MAC entity determines that the UL-SCH resource is available at a given time, it does not mean that the UL-SCH is available at that time.
[0069] In the BFR procedure, the MAC entity performs the following actions:
[0070] 1> If a beam fault recovery procedure is determined, for SCells for which candidate beam evaluation has been completed upon request, at least one BFR has been triggered and not canceled, and one of the serving cells of the MAC entity does not consist of two BFD-RS sets, 2>If the UL-SCH resource is available for the new transmission and the LCP result indicates that the UL-SCH resource can correspond to the BFR MAC CE and its subheaders, 3> The Multiplexing and Assembly procedure instructs the system to generate a BFR MAC CE. 2> Otherwise, if the UL-SCH resource is available for the new transmission and the LCP result can correspond to the BFR MAC CE and its subheaders from which the UL-SCH resource has been truncated, 3> Instruct the system to generate a BFR MAC CE with the multiplexing and assembly procedures truncated. 2>Otherwise, 3> Trigger an SR during SCell beam fault recovery for each SCell, provided that a BFR has been triggered and not canceled, and candidate beam evaluation has been completed as requested.
[0071] 1> The beam fault recovery procedure determines that at least one BFR of any BFD-RS set has been triggered and not canceled, and for the SCell, the candidate beam evaluation has been completed as requested, or 1> The beam fault recovery procedure determines that at least one BFR of one BFD-RS set has been triggered and not canceled, and for SpCell, the candidate beam evaluation has been completed upon request, or 1> The beam fault recovery procedure determines that at least one BFR has been triggered and not canceled, and for the SCell, the candidate beam evaluation has been completed upon request, and at least one serving cell of the MAC entity consists of two BFD-RS sets, 2>If UL-SCH resources are available for the new transmission and the LCP result indicates that UL-SCH resources can accommodate the extended BFR MAC CE and its subheaders, 3> Instruct the multiplexing and assembly procedures to generate an extended BFR MAC CE. 2> Otherwise, when the UL-SCH resource is available for the new transmission and the LCP result can accommodate the truncated extended BFR MAC CE and its subheaders, 3> Instruct the multiplexing and assembly procedures to generate a truncated extended BFR MAC CE. 2>Otherwise, 3> Trigger an SR for beam fault recovery for each set of BFD-RS when a BFR has been triggered and not canceled, and the evaluation of the requested candidate beam is complete. 3> Trigger an SR for SCell beam fault recovery for each set of SCells, provided that a BFR has been triggered and not canceled, and the evaluation of the requested candidate beam is complete.
[0072] For each serving cell, the RRC may configure a beam fault recovery procedure for the MAC entity, which is used to instruct the serving gNB to provide a new SSB or CSI-RS if a beam fault is detected in the serving SSB(s) / CSI-RS(s). Cell-level beam fault detection is supported in Rel-15 and Rel-16. The MAC entity performs the following actions:
[0073] If the beam fault recovery procedure determines that at least one BFR has been triggered and not canceled, If the UL-SCH resource is available for the new transmission and the LCP result indicates that this UL-SCH resource can accommodate the BFR MAC CE and its subheaders, then the Multiplexing and Assembly procedures are instructed to generate the BFR MAC CE. Otherwise, if the UL-SCH resource is available for the new transmission and the LCP result indicates that this UL-SCH resource can accommodate the Truncated BFR MAC CE and its subheaders, the Multiplexing and Assembly procedures are instructed to generate the Truncated BFR MAC CE. Otherwise, a Secondary Resonance (SR) is triggered for secondary cell beam fault recovery in each secondary cell where a BFR has been triggered and not canceled.
[0074] In R17 multi-TRP operation, beam fault detection is supported for a single per-TRP BFD-RS (Beam Fault Detection Reference Signal) set, and simultaneous configuration of cell-specific BFRs and TRP-specific BFRs in different CCs (Component Carriers) is supported, but simultaneous configuration of TRP-specific BFRs and Rel-15 / 16 BFRs (i.e., BeamFailureRecoveryConfig / BeamFailureRecoverySCellConfig-r16) in a single CC is not supported.
[0075] According to the agreement reached at the last meeting of RAN 2 (Radio Access Networks Working Group), legacy BFR MAC CEs and enhanced BFR MAC CEs are not triggered simultaneously. If two BFD-RS sets are configured for at least one cell, the enhanced BFR MAC CE is used for the BFR of serving cells that have or do not have a BFD-RS set configured.
[0076] Based on the above agreement, the BFR procedure described by the current protocol is shown in Figures 2 and 3.
[0077] Here, as shown in Figure 2, the MAC entity performs the following actions.
[0078] 1> The beam fault recovery procedure determines that at least one BFR has been triggered and not canceled for one secondary cell for which candidate beam evaluation is complete, and there are no serving cells for which two BFD-RS sets are configured for this MAC entity, 2>When the UL-SCH resource is available for the new transmission and, as a result of LCP, this UL-SCH resource can accommodate the BFR MAC CE and its subheader, 3> Instruct the Multiplexing and Assembly procedures to generate BFR MAC CE, 2> Otherwise, when the UL-SCH resource is available for the new transmission and, as a result of LCP, can accommodate the Truncated BFR MAC CE and its subheader, 3> The Multiplexing and Assembly procedure is instructed to generate a Truncated BFR MAC CE. 2>Otherwise, 3> Trigger an SR for secondary cell beam fault recovery in each secondary cell for which a BFR has been triggered and not canceled, and for which candidate beam evaluation has been completed.
[0079] Furthermore, as shown in Figure 3, the MAC entity performs the following actions.
[0080] 1> If the beam fault recovery procedure determines that it has triggered and not canceled at least one BFD-RS set of BFRs for one secondary cell in which candidate beam evaluation has been completed, or 1> If the beam fault recovery procedure determines that, for one special cell for which candidate beam evaluation has been completed, at least one BFD-RS set has triggered a BFR and has not been canceled, or 1> If the beam fault recovery procedure has triggered at least one BFR for one secondary cell where candidate beam evaluation is complete and is determined not to have been canceled, and two BFD-RS sets are configured for at least one serving cell of this MAC entity, 2>When the UL-SCH resource is available for the new transmission and, as a result of LCP, this UL-SCH resource can accommodate the Enhanced BFR MAC CE and its subheader, 3>Instruct the multiplexing and assembly procedures to generate Enhanced BFR MAC CE, 2> Otherwise, when the UL-SCH resource is available for the new transmission and, as a result of LCP, can accommodate the Truncated Enhanced BFR MAC CE and its subheader, 3>Instruct the multiplexing and assembly procedures to generate Truncated Enhanced BFR MAC CE, 2>Otherwise, 3> For each BFD-RS set where the BFR has been triggered and not canceled, and candidate beam evaluation is complete, trigger an SR to recover from beam faults. 3> Trigger an SR for secondary cell beam fault recovery in each secondary cell for which a BFR has been triggered and not canceled, and for which candidate beam evaluation has been completed.

[0086] <Example 1> Embodiments of the present invention provide a communication method in a cell non-continuous transmission / reception scenario, and will be described from the terminal device side.
[0087] Figure 4 is a schematic diagram of an example of a communication method according to an embodiment of the present invention. As shown in Figure 4, the method includes the following steps.
[0088] Step 401: If the network is in network energy saving mode, the terminal device does not trigger scheduling requests and / or performs actions related to network energy saving mode for pending scheduling requests.
[0089] Figure 4 above merely provides a schematic representation of an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between various steps may be appropriately adjusted, or several other steps may be added, or several steps may be removed. Those skilled in the art can make appropriate modifications based on the above description and are not limited to the description in Figure 4.
[0090] According to embodiments of the present invention, when the network is in network energy saving mode, the terminal device does not trigger the SR, thereby preventing the pending SR from triggering a random access procedure and reducing the network's energy consumption. Furthermore, when the network is in network energy saving mode, the terminal device performs an action related to network energy saving mode on the pending SR, thereby preventing the pending SR from releasing the uplink configuration to the terminal.
[0091] In some embodiments, the network energy saving mode is, Network power saving mode is activated. Cell non-continuous transmission / reception is configured and / or activated, and This means that the terminal device is in a deactivated state for non-continuous cell transmission / reception.
[0092] In the above embodiment, the activation of the network energy saving mode (the NES mode is activated) may, for example, be achieved when a network device instructs the terminal device to activate the network energy saving mode via at least one of RRC signaling (broadcast message or private message), MAC CE signaling, and DCI signaling. However, the present invention is not limited thereto, and the network energy saving mode may be activated by other means.
[0093] In the above embodiments, cell DTX / DRX is configured and / or activated, for example, by a network device configuring the parameters of cell DTX / DRX, such as period, on-duration time, etc., via RRC signaling (broadcast message or private message). Alternatively, for example, a network device may instruct a terminal device to activate (at least one) cell DTX / DRX via at least one of RRC signaling (broadcast message or private message), MAC CE signaling, and DCI signaling. Alternatively, for example, a network device may configure the parameters of cell DTX / DRX via RRC signaling (broadcast message or private message) and instruct a terminal device to activate (at least one) cell DTX / DRX via at least one of RRC signaling (broadcast message or private message), MAC CE signaling, and DCI signaling. However, the present invention is not limited thereto, and cell non-continuous transmission / reception may be configured and / or activated in other ways.
[0094] In the above embodiment, the UE being in an inactive state of cell DTX / DRX may, for example, mean that the terminal device enters a pause or deactivation period, or is not within the period of the cell DTX / DRX, depending on the cell DTX / DRX configuration. Alternatively, for example, if cell DTX / DRX is activated, depending on the cell DTX / DRX configuration, the terminal device may enter a pause or deactivation period, or is not within the period of the cell DTX / DRX.
[0095] In the above embodiment, the "cell discontinuous transmission / reception configuration" may, for example, involve a network device configuring the parameters of cell discontinuous transmission / reception, such as the period and on-duration time, via RRC signaling (broadcast messages or dedicated messages). However, the present invention is not limited to this, and other configuration methods may be used.
[0096] In the above embodiment, "cell non-continuous transmission / reception is activated" may mean, for example, that a network device instructs a terminal device to activate cell non-continuous transmission / reception (at least one of them) via at least one of the following: RRC signaling (broadcast message or dedicated message), MAC CE signaling, and DCI signaling. However, the present invention is not limited thereto, and other activation methods may be used.
[0097] In each of the above embodiments, the RRC signaling may be broadcast signaling, that is, the network device may perform the above instructions / configuration / activation by broadcast. The RRC signaling may also be dedicated signaling, that is, the network device may perform the above instructions / configuration / activation for a terminal device or a cell, etc.
[0098] In some embodiments, scheduling requests are Buffer Status Report (BSR) scheduling request, Beam Fault Recovery (BFR) scheduling request, Scheduling request for consistent Listen Before Talk failure recovery. Scheduling requests related to Access Backhaul Integration (IAB), Scheduling requests related to positioning, and It includes at least one scheduling request related to the non-terrestrial network (NTN).
[0099] In the above embodiment, the scheduling request for the BSR is, for example, a pending SR triggered according to the BSR procedure.
[0100] The following table shows the possible behaviors of MAC entities when an SR is triggered according to the BSR procedure.
[0101] [Table 1] According to this embodiment, when the network is in network energy saving mode, terminal devices do not trigger the BSR's SR. This reduces network energy consumption by preventing pending SRs from triggering random access procedures.
[0102] In the above embodiment, the BFR scheduling requests are, for example, SRs triggered for secondary cell BFRs (SCell BFRs), and also, for example, SRs triggered for BFD-RS set BFRs (BFD-RS set BFRs).
[0103] The following table shows the possible behaviors of MAC entities when SCell BFR triggers SR.
[0104] [Table 2] TIFF2026513332000004.tif68153 The following table shows the possible behaviors of MAC entities when a BFD-RS set BFR triggers an SR.
[0105] [Table 3] According to this embodiment, when the network is in network energy saving mode, BFR SRs, such as SCell BFR-triggered SRs and / or BFD-RS and BFR-triggered SRs, are not triggered. This reduces network energy consumption by preventing pending SRs from triggering random access procedures.
[0106] In the above embodiment, the scheduling request for consistent LBT failure recovery is, for example, an SR triggered by consistent LBT failure recovery.
[0107] The following table shows the possible behaviors of MAC entities in this example.
[0108] [Table 4] According to this embodiment, when the network is in network energy saving mode, the SR for consistent LBT failure recovery is not triggered. This reduces the network's energy consumption by avoiding pending SRs triggering random access procedures.
[0109] In the above embodiments, if the simultaneous use of IAB / Positioning / NTN and network energy saving is supported in some aspects, the scheduling request may be an SR related to IAB and / or an SR related to Positioning and / or an SR related to NTN.
[0110] For example, if the parent node or IAB-donor of an IAB node is in network power saving mode, an SR will not be triggered.
[0111] The following table shows the possible behaviors of MAC entities in this example.
[0112] [Table 5] As another example, for a MAC CE request to activate / deactivate the positioning gap, if the network is in network power saving mode, it will not trigger an SR.
[0113] The following table shows the possible behaviors of MAC entities in this example.
[0114] [Table 6] As another example, in NTN, the gNB has a UE timing advance value, i.e., T TA To provide this, the timing advance reporting procedure is used, and SR is not triggered when the network is in network power saving mode.
[0115] The following table shows the possible behaviors of MAC entities in this example.
[0116] [Table 7] According to this embodiment, if a network node is an IAB node or IAB-donor, or if the network is NTN, or if the network is used for positioning and the network is in network energy saving mode, an SR is not triggered. This reduces network energy consumption by avoiding pending SRs from triggering random access procedures.
[0117] In the above embodiment, in some other aspects, if the IAB or NTN does not support network energy saving and it is not possible to configure Positoning and network energy saving simultaneously, not triggering a scheduling request may mean not configuring the IAB and / or not configuring Positoning and / or not configuring NTN.
[0118] In some embodiments, the operation related to network energy saving mode is, Canceling a pending scheduling request (pending SR), Assuming there are no valid PUCCH resources configured for pending SR, To consider SR transmission as low-priority SR transmission, Putting the SR counter pending, Do not initiate a random access procedure. Do not perform clearing and / or release operations, and This includes using a maximum number of larger SR transmissions (sr-TransMax).
[0119] In the above embodiment, "considering SR transmission to be low-priority SR transmission" means, for example, that when the network is in network energy saving mode, SR transmission is considered to be low-priority SR transmission. Conversely, for example, when the network is not in network energy saving mode, SR transmission is considered to be high-priority SR transmission.
[0120] The following table shows one possible mode of protocol modification related to the above embodiment.
[0121] [Table 8] The following table shows other possible forms of protocol modification related to the above embodiment.
[0122] [Table 9] In the above embodiment, "pending the SR counter" means, for example, suspending the SR counter when the network is in network energy saving mode. Alternatively, for example, if the network is not in network energy saving mode, it means adding 1 to the SR counter.
[0123] The following table shows one possible mode of protocol modification related to the above embodiment.
[0124] [Table 10] In the above embodiment, "not starting a random access procedure" means, for example, not starting a random access procedure or a triggered random access procedure when the network is in network power saving mode. Alternatively, it means starting a random access procedure or a triggered random access procedure when the network is not in network power saving mode.
[0125] The following table shows one possible mode of protocol modification related to the above embodiment.
[0126] [Table 11] In the above embodiment, "using a larger maximum number of SR transmissions (sr-TransMax)" means, for example, configuring the maximum number of SR transmissions as an infinite value, or, for example, if the maximum number of SR transmissions is not configured, the terminal device considers the maximum number of SR transmissions to be an infinite value.
[0127] The following table shows one possible mode of protocol modification related to the above embodiment.

[0129] [Table 13] TIFF2026513332000017.tif152153 In the example above, the protocol description for "sr-TransMax" may also be as follows:
[0130] [Table 14] In the above embodiment, "not performing a clearing and / or release operation" means, for example, not performing a clearing and / or release operation when the network is in network power saving mode, and for example, performing a clearing and / or release operation when the network is not in network power saving mode.
[0131] In the above embodiment, performing a clearing and / or release operation when the network is not in network energy saving mode may include, for example, performing a clearing and / or release operation when the network is not in network energy saving mode and the SR counter has reached its maximum value.
[0132] In the above embodiment, if the network is not in network energy saving mode, performing a clearing and / or release operation may further include initiating a random access procedure on a special cell and / or canceling all pending SRs.
[0133] In each of the above embodiments, the “clearing” operation includes clearing any configured downlink assignments and uplink grants, and / or clearing any PUSCH resources for semi-persistent CSI reporting.
[0134] In each of the above embodiments, the “release” operation includes notifying the RRC to release PUCCH for all serving cells and / or notifying the RRC to release SRS for all serving cells.
[0135] For example, if the SR counter reaches its maximum value and the network is not in network power saving mode, notify the RRC to release PUCCH for all serving cells, notify the RRC to release SRS for all serving cells, clear all configured downlink assignments and uplink grants, clear all PUSCH resources for semi-persistent CSI reporting, initiate random access procedures in special cells, and cancel all pending SRs.
[0136] Furthermore, for example, if the SR counter reaches its maximum value and the network is in network power saving mode, a random access procedure is initiated in the special cell to cancel all pending SRs.
[0137] Additionally, for example, if the SR counter reaches its maximum value, a random access procedure is initiated in the special cell to cancel all pending SRs. If the network is not in network power saving mode, the RRC is notified to release PUCCH for all serving cells, the RRC is notified to release SRS for all serving cells, all configured downlink assignments and uplink grants are cleared, and all PUSCH resources for semi-persistent CSI reporting are cleared.
[0138] The above embodiments illustrate examples of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, each of the above embodiments may be used individually, or one or more of the above embodiments may be used in combination.
[0139] According to this embodiment, when the network is in network energy saving mode, the terminal device does not trigger the SR, thereby preventing the pending SR from triggering a random access procedure and reducing the network's energy consumption. Furthermore, when the network is in network energy saving mode, the terminal device performs network energy saving mode-related actions on the pending SR, preventing the pending SR from releasing the uplink configuration to the terminal.
[0140] <Example 2> The embodiments of the present invention provide a communication method in a cell non-continuous transmission / reception scenario and will be described from the network device side. Descriptions of the same content as in Embodiment 1 will be omitted.
[0141] Figure 5 is a schematic diagram of another example of a communication method according to an embodiment of the present invention. As shown in Figure 5, the method includes the following steps.
[0142] Step 501: The network device instructs the terminal device with information related to network energy saving.
[0143] According to this embodiment, the network device instructs the terminal device with information related to network energy saving so that when the network is in network energy saving mode, the terminal device does not trigger an SR, or performs an action related to network energy saving mode for a pending SR. This prevents the pending SR from triggering a random access procedure, reduces network energy consumption, and prevents the pending SR from causing the terminal to release the uplink configuration.
[0144] In some embodiments, the network device instructing a terminal device to provide information related to network energy saving may, for example, mean that the network device instructs the terminal device to be in network energy saving mode. The present invention is not limited to a specific instruction method, and instructions may be given by transmitting instruction information, transmitting configuration information, or by other means. Furthermore, the present invention is not limited to a method of transporting instruction information or configuration information, and may transport it through various possible signaling methods.
[0145] In the above embodiment, the network energy saving mode is: Network power saving mode is activated (the NES mode is activated). Cell non-continuous transmit / receive (cell DTX / DRX) is configured and / or activated, and This means that the terminal device is in an inactive state of cell DTX / DRX (the UE is in an inactive state of cell DTX / DRX).
[0146] For example, if the network energy saving mode is "the NES mode is activated", the network device may instruct terminal devices to activate the network energy saving mode via at least one of the RRC signaling, MAC CE signaling, and DCI signaling (502).
[0147] As another example, if the network energy saving mode is “Cell discontinuous transmit / receive is configured and / or activated”, the network device may configure the parameters for cell discontinuous transmit / receive via RRC signaling (503).
[0148] As another example, if the network energy saving mode is “Cell discontinuous transmit / receive is configured and / or activated”, the network device may instruct the activation of cell discontinuous transmit / receive on at least one terminal device via at least one of the RRC signaling, MAC CE signaling and DCI signaling (504).
[0149] As another example, if the network energy saving mode is "the terminal device is in an inactive state for cell discontinuous transmission / reception", the network device may transmit the cell discontinuous transmission / reception configuration to the terminal device (505). This causes the terminal device to enter a pause or deactivation period, or the terminal device to be out of the cell discontinuous transmission / reception period, or, if cell discontinuous transmission / reception is activated, the terminal device to enter a pause or deactivation period, or the terminal device to be out of the cell discontinuous transmission / reception period.
[0150] In each of the above embodiments, the RRC signaling may be broadcast signaling or dedicated signaling.
[0151] In some embodiments, the network device instructing terminal devices on network energy saving information may involve, for example, the network device coordinating the SR configuration and cell DTX / DRX on-duration time.
[0152] In the above embodiment, coordinating the SR configuration and the cell non-continuous transmit / receive on duration may, for example, mean that the cell non-continuous transmit / receive inactive time does not have a valid PUCCH resource, or it may mean that a valid PUCCH resource is present within the cell non-continuous transmit / receive activation time.
[0153] In some embodiments, the network device may instruct terminal devices to provide information related to network energy saving, for example, if the network device supports one of IAB, NTN, and positioning, the network device may either be in network energy saving mode or not instruct terminal devices to be in network energy saving mode.
[0154] In some embodiments, the network energy saving mode is, Network power saving mode is activated (the NES mode is activated). Cell non-continuous transmit / receive (cell DTX / DRX) is configured and / or activated, and This means that the terminal device is in an inactive state of cell DTX / DRX (the UE is in an inactive state of cell DTX / DRX).
[0155] The network energy-saving mode described above has already been explained in Example 1, and that explanation is incorporated here and omitted here.
[0156] In some embodiments, when a network device indicates that it is in network energy saving mode, the network device does not support one of IAB, NTN, and positioning.
[0157] The above embodiments illustrate examples of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, each of the above embodiments may be used individually, or one or more of the above embodiments may be used in combination.
[0158] According to this embodiment, when the network is in network energy saving mode, the terminal device does not trigger the SR, thereby preventing the pending SR from triggering a random access procedure and reducing the network's energy consumption. Furthermore, when the network is in network energy saving mode, the terminal device performs network energy saving mode-related actions on the pending SR, preventing the pending SR from releasing the uplink configuration to the terminal.
