AI Technical Summary
In the non-continuous transmission/reception scenario of cells in the 5G network, the terminal equipment does not transmit/receive candidate channels/signals during the inactive phase, causing scheduling request interruption and increasing network energy consumption, and the pending scheduling request may trigger the random access process. Increase energy consumption.
In the network energy-saving mode, the terminal device does not trigger scheduling requests and performs behaviors related to the network energy-saving mode, such as canceling pending scheduling requests. It is considered that there are no valid PUCCH resources and uses a larger maximum number of SR transmissions to avoid randomness. The access process reduces network energy consumption.
By preventing pending scheduling requests from triggering the random access process, network energy consumption is reduced, and terminal devices are prevented from releasing uplink configurations, thereby improving network energy saving.

Abstract
Description
Communication method and device in cell discontinuous transmission / reception scenario Technical Field
[0001] The embodiments of the present application relate to the field of communication technologies. Background Art
[0002] As a crucial component of new global infrastructure, 5G (fifth-generation mobile communication technology) communications networks have experienced rapid global development in recent years. As networks scale, operators' energy consumption continues to rise. According to data released by China's Ministry of Industry and Information Technology, energy consumption is projected to increase by approximately 80% between 2015 and 2022.
[0003] With the rollout of 5G and the widespread commercialization of 5G active antenna units (AAUs), energy consumption is expected to increase exponentially compared to the remote radio units (RRUs) primarily used in 3G and 4G, due to the higher power consumption of AAUs. 5G defines three major service types: enhanced mobile broadband (eMBB), massive machine type of communication (mMTC), and ultra-reliable low-latency communication (URLLC). This is driving an increase in bursty small packet traffic and the 24 / 7 operation of base stations. The average daily energy consumption of 5G sites is expected to be more than double that of 4G.
[0004] The 3rd Generation Partnership Project (3GPP) has introduced key technologies such as Massive MIMO and increased RF bandwidth in the 5G era. 5G supports higher data rates and greater data traffic, requiring more transmission bandwidth. High-frequency bands will be the primary frequency band for future 5G expansion. However, the transmission characteristics of high-frequency bands limit site coverage, resulting in denser deployment of 5G sites. Furthermore, the increased energy consumption will place significant pressure on operators' operating costs. Therefore, network energy conservation is crucial for reducing operating costs, and energy conservation in 5G networks is a pressing issue.
[0005] To achieve energy conservation, network devices can implement energy conservation in the time, frequency, spatial, and / or energy domains, depending on network load. For example, in the spatial and energy domains, network devices can power down some antennas when the load is low. In the time domain, network devices can implement cell-level discontinuous transmission / reception technology, which prevents network devices from transmitting and / or receiving signals during certain sleep periods, thereby achieving energy conservation.
[0006] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.
[0007] Summary of the Invention
[0008] The inventors have discovered that for connected mode user equipments (UEs), during the cell discontinuous transmitting / receiving (DTX / DRX) inactive phase, at least the following candidate channels / signals are considered not to be transmitted / received:
[0009] Downside:
[0010] Periodic / semi-persistent CSI-RS (Channel State Information-Reference Signal) (including TRS (Tracking RS));
[0011] PRS (Positioning Reference Signal, positioning reference signal);
[0012] PDCCH (Physical Downlink Control Channel) scrambled with the UE-specific RNTI (Radio Network Temporary Identity);
[0013] PDCCH in Type-3 CSS (Common Search Space);
[0014] SPS PDCCH (semi-persistently scheduled PDCCH);
[0015] Uplink:
[0016] SR (Scheduling Request);
[0017] Periodic / semi-persistent CSI (Channel State Information) report (CSI report);
[0018] Periodic / semi-persistent SRS (Sounding Reference Signal, detection (sounding) reference signal);
[0019] CG (Configured Grant)-PUSCH (Physical Uplink Shared Channel);
[0020] That is, for connected mode UEs, during the cell DTX / DRX inactive phase, the UE does not send an SR. This interrupts the process of triggering an SR to request uplink resources and the sending of the triggered pending SR, thus causing problems.
[0021] To address the above issues, embodiments of the present application provide a communication method and apparatus in a cell discontinuous transmission / reception scenario.
[0022] According to one aspect of an embodiment of the present application, a communication apparatus is provided, configured in a terminal device, the apparatus comprising:
[0023] A processing unit is configured to not trigger a scheduling request and / or perform actions related to the network energy saving mode for a pending scheduling request (SR) when the network is in the network energy saving mode.
[0024] In some embodiments, the network energy saving mode refers to at least one of the following:
[0025] The NES mode is activated.
[0026] Cell discontinuous transmission / reception (cell DTX / DRX) is configured and / or activated;
[0027] The terminal equipment is in the inactive state of cell DTX / DRX.
[0028] In some embodiments, the scheduling request includes at least one of the following:
[0029] Buffer Status Report (BSR) scheduling request;
[0030] Beam Failure Recovery (BFR) scheduling request;
[0031] Scheduling requests for consistent LBT failure recovery;
[0032] Integration and Access Backhaul (IAB) related scheduling requests;
[0033] Positioning-related scheduling requests;
[0034] Non-terrestrial network (NTN) related scheduling requests.
[0035] In some embodiments, the behaviors related to the network energy saving mode include at least one of the following:
[0036] Cancel the pending scheduling request (pending SR);
[0037] It is considered that there are no valid PUCCH resources configured for the pending SR;
[0038] Consider SR transmission to be a low-priority SR transmission;
[0039] Suspend SR counter;
[0040] Do not initiate a random access process;
[0041] No emptying and / or releasing operations are performed;
[0042] Use a larger maximum SR transmission time (sr-TransMax).
[0043] According to another aspect of an embodiment of the present application, a communication device is provided, configured in a network device, the device comprising:
[0044] The first indicating unit indicates information related to network energy saving to the terminal device.
[0045] One of the beneficial effects of the embodiments of the present application is that, according to the embodiments of the present application, when the network is in network energy-saving mode, the terminal device does not trigger an SR, thereby preventing the pending SR from triggering a random access procedure, thereby reducing network energy consumption. Furthermore, when the network is in network energy-saving mode, for a pending SR, the terminal device performs actions related to the network energy-saving mode, thereby preventing the pending SR from causing the terminal to release its uplink configuration.

[0074] In the following description, “if,” “in the case of,” and “when” can be used interchangeably without causing confusion.
[0075] In an embodiment of the present application, the scheduling request is used to request UL-SCH (Uplink Shared Channel) resources for new transmission.
[0076] A MAC (Media Access Control) entity can be configured with zero, one, or multiple 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 failure recovery and persistent LBT (listen before talk) failure recovery, at most one PUCCH resource for SR is configured per BWP. For logical channels serving radio bearers configured with SDT (Short Data Transfer), no PUCCH resources for SR are configured for SDT. For beam failure recovery of the BFD-RS (Beam Failure Detection-Reference Signal) set of the serving cell, at most two PUCCH resources for SR are configured per BWP configuration. For positioning measurement gap activation / deactivation requests, a dedicated SR configuration is configured.
[0077] Each SR configuration corresponds to one or more logical channels and / or SCell beam failure recovery and / or persistent LBT failure recovery and / or beam failure recovery of a BFD-RS set and / or positioning measurement gap activation / deactivation request. Each logical channel, SCell beam failure recovery, beam failure recovery of a BFD-RS set and persistent LBT failure recovery can be mapped to zero or one SR configuration configured by RRC (Radio Resource Control). The SR configuration of the logical channel that triggers the BSR (Buffer Status Report) or the SCell beam failure recovery or the beam failure recovery of a BFD-RS set or the persistent LBT failure recovery (if such a configuration exists) or the positioning measurement gap activation / deactivation request is regarded as the corresponding SR configuration for the triggered SR. Any SR configuration can be used for the SR triggered by a Pre-emptive BSR or a timing advance report.
[0078] The RRC configures the following parameters for the scheduling request process:
[0079] -sr-ProhibitTimer (configured per SR);
[0080] -sr-TransMax (per SR configuration).
[0081] The following UE variables are used in the scheduling request procedure:
[0082] -SR_COUNTER (according to SR configuration).
[0083] If an SR is triggered and no other SR corresponding to the same SR configuration is pending, the MAC entity shall set the SR_COUNTER of the corresponding SR configuration to 0.
[0084] When a SR is triggered, it should be considered pending until it is canceled.
[0085] Before a MAC PDU (Protocol Data Unit) is assembled, all pending SRs for BSRs triggered according to the BSR procedure shall be canceled, and each corresponding sr-ProhibitTimer (SR prohibit timer) shall be stopped when the MAC PDU is transmitted, and the PDU includes a long or short BSR MAC CE (Control Element) containing the buffer status up to and including the last event that triggered the BSR before the MAC PDU is assembled. When the UL (Uplink) grant can accommodate all pending data available for transmission, all pending SRs for BSRs triggered according to the BSR procedure shall be canceled, and each corresponding sr-ProhibitTimer shall be stopped.
[0086] For each pending SR that is not triggered according to the BSR procedure of the serving cell, the MAC entity shall:
[0087] 1> if the SR is triggered by the Pre-emptive BSR procedure before MAC PDU assembly and a MAC PDU containing the relevant Pre-emptive BSR-MAC CE is sent; or
[0088] 1> If the SR is triggered by beam failure recovery of an SCell and a MAC PDU is sent, and the PDU includes a MAC CE for BFR (Beam Failure Recovery), the MAC CE contains beam failure recovery information for the SCell; or
[0089] 1> If the SR is triggered by beam failure recovery of the BFD-RS set of the serving cell, and a MAC PDU is sent, and the PDU includes an enhanced BFR MAC CE or a truncated enhanced BFR MAC CE, the BFR MAC CE contains beam failure recovery information for the BFD-RS set of the serving cell; or
[0090] 1> If the SR is triggered by beam failure recovery of an SCell and the SCell is deactivated; or
[0091] 1> If the SR is triggered by beam failure recovery of the BFD-RS set of the SCell, and the SCell is deactivated; or
[0092] 1> If the SR is triggered by a Positioning Measurement Gap Activation / Deactivation Request, and the Positioning Measurement Gap Activation / Deactivation Request MAC CE that triggered the SR has been cancelled; or
[0093] 1> If the SR is triggered by the recovery of a persistent LBT failure of the SCell, and a MAC PDU is sent, and the MAC PDU includes an LBT Failure MAC CE indicating a persistent LBT failure of the SCell; or
[0094] 1> If the SR is triggered by the recovery of a persistent LBT failure of the SCell, and all triggered persistent LBT failures of the SCell are canceled; or
[0095] 1> If the SR is triggered by a timing advance report and all triggered timing advance reports are canceled:
[0096] 2>Cancel the pending SR and stop the corresponding sr-ProhibitTimer, if it is running.
[0097] Only PUCCH resources on the BWP that are active at the time of the SR transmission opportunity are considered valid.
[0098] As long as at least one SR is pending, for each pending SR, the MAC entity will:
[0099] 1> If the MAC entity does not configure valid PUCCH resources for the pending SR:
[0100] 2>Initiate a random access procedure on the SpCell (special cell) and cancel the suspended SR.
[0101] 1> Otherwise, for the SR configuration of the corresponding pending SR:
[0102] 2> When the MAC entity has an SR transmission opportunity on a valid PUCCH resource configured for SR; and
[0103] 2> If sr-ProhibitTimer is not running at the time of the SR transmission opportunity; and
[0104] 2> If the PUCCH resources used for SR transmission opportunities do not overlap with measurement gaps:
[0105] 3> If the PUCCH resources used for the SR transmission opportunity do not overlap with UL-SCH (Uplink Shared Channel) resources (UL-SCH resources not allowed to be transmitted simultaneously with SR through the configuration of simultaneousPUCCH-PUSCH or simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup or simultaneousSR-PUSCH-diffPUCCH-Groups) nor with SL-SCH (Sidelink Shared Channel) resources; or
[0106] 3> if the MAC entity is able to perform the SR transmission simultaneously with the transmission of SL-SCH resources; or
[0107] 3> If the MAC entity is configured with lch-based Prioritization and the PUCCH resources used for the SR transmission opportunity do not overlap with the PUSCH duration of the uplink grant received in the random access response, or do not overlap with the PUSCH duration of the uplink grant addressed to the temporary C-RNTI (Cell Radio Network Temporary Identifier, cell radio network temporary identifier), or do not overlap with the MSGA (message A, message A) payload overlaps with the PUSCH duration, and the PUCCH resource of the SR transmission opportunity that triggered the pending SR overlaps with any other UL-SCH resource, and the physical layer is able to signal the SR on a valid PUCCH resource for the SR, and the priority of the logical channel that triggered the SR is higher than the priority of the uplink grant of any UL-SCH resource, where the uplink grant has not been de-prioritized and its simultaneous transmission with the SR is not allowed by the configuration of simultaneousPUCCH-PUSCH or simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup or simultaneousSR-PUSCH-diffPUCCHgroups, and the priority of the uplink grant is determined; or
[0108] 3> If sl-PrioritizationThres and ul-PrioritizationThres are configured, and the PUCCH resources of the SR transmission opportunity that triggers a pending SR overlap with any UL-SCH resources carrying a MAC PDU, and the value of the priority determined to trigger the SR is lower than sl-PrioritizationThres, and the value of the highest priority of the logical channels in the MAC PDU is higher than or equal to ul-PrioritizationThres, and any prioritized MAC CE is not included in the MAC PDU, the MAC PDU is not prioritized by upper layer; or
[0109] 3> if for the SR transmission opportunity that triggered the pending SR, the SL-SCH resources overlap with the PUCCH resources and the MAC entity cannot perform the SR transmission concurrently with the transmission of the SL-SCH source, and the transmission on the SL-SCH resources is not prioritized or the priority value of the logical channel that triggered the SR is lower than ul-PrioritizationThres (if configured); or
[0110] 3> If for the SR transmission opportunity of a triggered pending SR, the SL-SCH resources overlap with the PUCCH resources and the MAC entity cannot perform the SR transmission simultaneously with the transmission of the SL-SCH, and, for the SL-SCH resources, the priority of the determined triggered SR is higher than the priority of the determined MAC PDU:
[0111] 4> Treat SR transmission as SR transmission with priority.
[0112] 4> Treat other overlapping uplink grants (if any) as deprioritized uplink grants, except for overlapping uplink grants whose simultaneous transmission is allowed by the configuration of simultaneousPUCCH-PUSCH or simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup or simultaneousSR-PUSCH-diffPUCCH-Groups;
[0113] 4> If the deprioritized uplink grant is an uplink grant configured with autonomousTx (whose PUSCH has been started):
[0114] 5> Stop the configuredGrantTimer of the corresponding HARQ process of the de-prioritized uplink grant;
[0115] 5> Stop the cg-RetransmissionTimer of the corresponding HARQ process of the de-prioritized uplink grant.
[0116] 4>If SR_COUNTER <sr-TransMax:
[0117] 5> instructing the physical layer to signal the SR on a valid PUCCH resource for SR;
[0118] 5> If no LBT failure indication is received from the lower layer:
[0119] 6>Increase SR_COUNTER by 1;
[0120] 6>Start sr-ProhibitTimer.
[0121] 5> Otherwise, if lbt-FailureRecoveryConfig is not configured:
[0122] 6>Increment SR_COUNTER by 1.
[0123] 4> Otherwise:
[0124] 5> Notify RRC to release PUCCH of all serving cells;
[0125] 5> Notify RRC to release SRS of all serving cells;
[0126] 5> Clear any configured downlink allocation and uplink authorization;
[0127] 5> Clear any PUSCH resources used for semi-persistent CSI reporting;
[0128] 5>Initiate a random access process on the SpCell and cancel all pending SRs.
[0129] 3> Otherwise:
[0130] 4> Treat SR transmission as de-prioritized SR transmission.
[0131] NOTE 1: Except for SR for SCell beam failure recovery, when the MAC entity has more than one overlapping valid PUCCH resource for SR transmission opportunities, the selection of which valid PUCCH resource for SR to signal the SR is left to the UE implementation.
[0132] NOTE 2: If more than one separate SR triggers the instruction from the MAC entity to the PHY layer to signal the SR on the same valid PUCCH resource, the SR_COUNTER of the related SR configuration is incremented only once.
[0133] NOTE 3: When the MAC entity has a pending SR for SCell beam failure recovery and the MAC entity has one or more PUCCH resources (in addition to the PUCCH resources for the pending SR for beam failure recovery of a BFD-RS set), the MAC entity only considers the PUCCH resources for SCell beam failure recovery to be valid. When the MAC entity has a pending SR for beam failure recovery of a BFD-RS set of a serving cell and the MAC entity has one or more PUCCH sources (in addition to the PUCCH resources for the pending SR for beam failure recovery) that overlap with the PUCCH resources for beam failure recovery of the BFD-RS set for an SR transmission opportunity, the MAC entity only considers the PUCCH resources for beam failure recovery of the BFD-RS set to be valid.
[0134] NOTE 4: For UEs operating in semi-static channel access mode, PUCCH resources that overlap with a set of consecutive symbols that the UE does not transmit before the start of the next channel occupancy time are considered invalid.
[0135] NOTE 5: If the MAC entity is configured with ICH-based Prioritization, the MAC entity does not consider UCI multiplexing when determining whether valid PUCCH resources for SR transmission can be signaled by the physical layer and whether the SR transmission opportunity overlaps with the PUSCH duration of the uplink grant of the MSGA payload.
[0136] NOTE 6: When the MAC entity has PUCCH resources for pending SR for SCell beam failure recovery that overlap with PUCCH resources for pending SR for beam failure recovery for a BFD-RS set for an SR transmission opportunity, it is up to the UE implementation to select the PUCCH resources for SCell beam failure recovery or the PUCCH resources for beam failure recovery for a BFD-RS set.
[0137] During the BSR process, the MAC entity will:
[0138] 1> If the cache status reporting process determines that at least one BSR is triggered and not canceled:
[0139] 2> If UL-SCH resources are available for new transmission and the result of logical channel priority is that the UL-SCH resources can accommodate the BSR MAC CE plus its subheader;
[0140] 3> Instructs the multiplexing and assembly process to generate BSR MAC CE(s);
[0141] 3> Except when all generated BSRs are long or short truncated or extended long or short phase BSRs, start or restart periodicBSR-Timer;
[0142] 3> Enable or restart retxBSR-Timer.
[0143] 2>If the regular BSR is triggered and the logicalChannelSR-DelayTimer is not running;
[0144] 3> if there are no UL-SCH resources available for new transmission; or
[0145] 3> If the MAC entity is configured with an uplink grant and for a logical channel with logicalChannelSR-Mask set to false, a regular BSR is triggered; or
[0146] 3> If the UL-SCH resources available for new transmission do not meet the LCP (Logical Channel Prioritization) mapping constraints configured for the logical channel that triggered the BSR;
[0147] 4>Trigger scheduling request.
[0148] NOTE 2: UL-SCH resources are considered available if the MAC entity is configured or receives or determines an uplink grant. If the MAC entity has determined that UL-SCH resources are available at a given point in time, this does not mean that UL-SCH is available at that point in time.
[0149] During the BFR process, the MAC entity will:
[0150] 1> If the beam failure recovery procedure determines that, for an SCell for which the evaluation of candidate beams has been completed as required, at least one BFR has been triggered and not cancelled, and if none of the serving cells of this MAC entity has two BFD-RS sets configured:
[0151] 2> If UL-SCH resources are available for the new transmission and if the result of the LCP is that the UL-SCH resources can accommodate the BFR MAC CE plus its subheader:
[0152] 3> Instructs the multiplexing and assembly process to generate BFR MAC CE;
[0153] 2> Otherwise if UL-SCH resources are available for the new transmission and if the result of the LCP is that the UL-SCH resources can accommodate the truncated BFR MAC CE plus its subheader:
[0154] 3> Instructs the multiplexing and assembly process to generate a truncated BFR MAC CE;
[0155] 2> Otherwise:

[0167] For each serving cell, RRC can configure the MAC entity with a beam failure recovery procedure, which is used to indicate a new SSB or CSI-RS to the serving gNB when beam failure is detected on the serving SSB(s) / CSI-RS(s). In Rel-15 and Rel-16, cell-level beam failure detection is supported. The MAC entity shall:

[0203] The embodiments of the present application are described below with reference to the accompanying drawings and specific implementation methods.
[0204] Embodiments of the first aspect
[0205] An embodiment of the present application provides a communication method in a cell discontinuous transmission / reception scenario, which is described from the side of a terminal device.
[0206] FIG4 is a schematic diagram of a communication method according to an embodiment of the present application. As shown in FIG4 , the method includes:
[0207] 401: When the network is in the network energy-saving mode, the terminal device does not trigger a scheduling request and / or performs actions related to the network energy-saving mode for a pending scheduling request.
[0208] It is worth noting that FIG4 above only schematically illustrates an embodiment of the present application, and the present application is not limited thereto. For example, other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of FIG4 above.
[0209] According to the above embodiment, when the network is in network energy-saving mode, the terminal device does not trigger an SR. This prevents a pending SR from triggering a random access procedure, thereby reducing network energy consumption. Furthermore, when the network is in network energy-saving mode, the terminal device performs actions related to the pending SR in response to the network energy-saving mode. Therefore, a pending SR does not cause the terminal to release its uplink configuration.
[0210] In some embodiments, the network energy saving mode is one of the following:
[0211] Network energy saving mode is activated;
[0212] Discontinuous transmission / reception of the cell is configured and / or activated;
[0213] The terminal device is in the inactive phase of discontinuous transmission / reception of the cell.
[0214] In the above embodiment, the network energy saving mode is activated (the NES mode is activated), for example, the network device instructs the terminal device to activate the network energy saving mode through at least one of RRC signaling (broadcast or dedicated message), MAC CE signaling, and DCI signaling. However, the present application is not limited to this, and the network energy saving mode can also be activated by other means.
[0215] In the above embodiment, cell discontinuous transmission / reception (cell DTX / DRX is configured / activated) is configured and / or activated, for example, the network device configures the parameters of cell discontinuous transmission / reception, such as period, on-duration time, etc., through RRC signaling (broadcast or dedicated message); for another example, the network device indicates the activation of (at least one) cell discontinuous transmission / reception of the terminal device through at least one of RRC signaling (broadcast or dedicated message), MAC CE signaling and DCI signaling; for another example, the network device configures the parameters of cell discontinuous transmission / reception through RRC signaling (broadcast or dedicated message), and indicates the activation of at least one cell discontinuous transmission / reception of the terminal device through at least one of RRC signaling (broadcast or dedicated message), MAC CE signaling and DCI signaling. However, the present application is not limited to this, and cell discontinuous transmission / reception may also be configured and / or activated in other ways.
[0216] In the above embodiment, the terminal device is in the inactive stage of cell discontinuous transmission / reception (the UE is in inactive state of cell DTX / DRX). For example, according to the cell discontinuous transmission / reception configuration, the terminal device enters the sleep or inactive time, or the terminal device is not within the duration of the cell discontinuous transmission / reception; for another example, according to the cell discontinuous transmission / reception configuration, when the cell discontinuous transmission / reception is activated, the terminal device enters the sleep or inactive time, or the terminal device is not within the duration of the cell discontinuous transmission / reception.
[0217] In the above embodiment, "cell discontinuous transmission / reception configuration" may be, for example, that the network device configures the cell discontinuous transmission / reception parameters, such as the period, on-duration time, etc., through RRC signaling (broadcast or dedicated message). However, the present application is not limited thereto, and other configuration methods may also be used.
[0218] In the above embodiment, "cell discontinuous transmission / reception is activated", for example, the network device may indicate the activation of (at least one) cell discontinuous transmission / reception of the terminal device through at least one of RRC signaling (broadcast or dedicated message), MAC CE signaling, and DCI signaling. However, the present application is not limited to this, and other activation methods may also be used.
[0219] In the aforementioned embodiments, RRC signaling may be broadcast signaling, that is, the network device may perform the above-mentioned indication / configuration / activation by broadcasting; RRC signaling may also be dedicated signaling, that is, the network device may perform the above-mentioned indication / configuration / activation for a certain terminal device or a certain cell, etc.
[0220] In some embodiments, the scheduling request includes at least one of the following:
[0221] Buffer Status Report (BSR) scheduling request;
[0222] Beam Failure Recovery (BFR) scheduling request;
[0223] Scheduling requests for consistent LBT failure recovery;
[0224] Integration and Access Backhaul (IAB) related scheduling requests;
[0225] Positioning-related scheduling requests;
[0226] Non-terrestrial network (NTN) related scheduling requests.
[0227] In the above embodiment, the BSR scheduling request is, for example, a pending SR triggered according to a BSR process.
[0228] The following table shows the possible behaviors of the MAC entity when an SR is triggered according to the BSR procedure:
[0229] According to this embodiment, when the network is in the network energy-saving mode, the terminal device does not trigger the SR of the BSR, thereby avoiding the suspended SR from triggering the random access process, thereby reducing network energy consumption.
[0230] In the above embodiment, the BFR scheduling request is, for example, an SR triggered by a secondary cell BFR (SCell BFR), or another example, an SR triggered by a BFD-RS set BFR (BFD-RS set BFR).
[0231] The following table shows the possible behaviors of the MAC entity when SCell BFR triggers SR:
[0232] The following table shows the possible behaviors of the MAC entity when BFD-RS set BFR triggers SR:
[0233] According to this embodiment, when the network is in network energy-saving mode, BFR-triggered SRs, such as SCell BFR-triggered SRs and / or BFD-RS combined with BFR-triggered SRs, are not triggered. This prevents pending SRs from triggering random access procedures, thereby reducing network energy consumption.
[0234] In the above embodiment, the scheduling request for consistent LBT failure recovery is, for example, an SR triggered by consistent LBT failure recovery.
[0235] The following table shows the possible behaviors of the MAC entity in this example:
[0236] According to this embodiment, when the network is in the network energy-saving mode, the SR for consistent LBT failure recovery is not triggered, thereby avoiding the random access process triggered by the pending SR, thereby reducing network energy consumption.
[0237] In the above embodiment, in some implementations, if IAB / Positioning / NTN and network energy saving are supported simultaneously, the above scheduling request may also be an IAB-related SR and / or a Positioning-related SR and / or an NTN-related SR.
[0238] For example, when the parent node or IAB-donor of an IAB node is in the network energy-saving mode, SR is not triggered.
[0239] The following table shows the possible behaviors of the MAC entity in this example:
[0240] For another example, for the positioning measurement gap activation / deactivation request MAC CE, when the network is in the network energy saving mode, no SR is triggered.
[0241] The following table shows the possible behaviors of the MAC entity in this example:
[0242] For example, in NTN, in order to provide the UE timing advance value, T TA ,Using the timed advance reporting process, when the network is in the network energy saving mode, SR is not triggered.
[0243] The following table shows the possible behaviors of the MAC entity in this example:
[0244] According to this embodiment, when the network node is an IAB node or IAB-donor, or the network is an NTN, or the network is used for positioning, and the network is in a network energy-saving mode, SR is not triggered. This can prevent a pending SR from triggering a random access procedure, thereby reducing network energy consumption.
[0245] In the above embodiment, in other implementations, IAB or NTN does not support network energy saving, and Positoning and network energy saving are not configured at the same time, then not triggering the scheduling request may mean not configuring IAB and / or not configuring Positoning and / or not configuring NTN.
[0246] In some embodiments, the behaviors related to the network energy saving mode include at least one of the following:
[0247] Cancel the pending scheduling request (pending SR);
[0248] It is considered that there are no valid PUCCH resources configured for the pending SR;
[0249] Consider SR transmission to be a low-priority SR transmission;
[0250] Suspend SR counter;
[0251] Do not initiate a random access process;
[0252] No emptying and / or releasing operations are performed;
[0253] Use a larger maximum SR transmission time (sr-TransMax).
[0254] In the above embodiment, “SR transmission is considered to be a low-priority SR transmission”. For example, if the network is in the network energy-saving mode, the SR transmission is considered to be a low-priority SR transmission; for another example, if the network is not in the network energy-saving mode, the SR transmission is considered to be a high-priority SR transmission.
[0255] The following table shows a possible modification of the protocol according to the above embodiment:
[0256] The following table shows another possibility of protocol modification according to the above embodiment:
[0257] In the above embodiment, “suspending the SR counter” means, for example, suspending the SR counter if the network is in the network energy-saving mode; or adding 1 to the SR counter if the network is not in the network energy-saving mode.
[0258] The following table shows a possible modification of the protocol according to the above embodiment:
[0259] In the above embodiment, “not initiating a random access process” means, for example, not initiating a random access process or not initiating a triggered random access process if the network is in a network energy-saving mode; or initiating a random access process or a triggered random access process if the network is not in a network energy-saving mode.
[0260] The following table shows a possible modification of the protocol according to the above embodiment:
[0261] In the above embodiment, "using a larger maximum SR transmission number (sr-TransMax)", for example, configuring the maximum SR transmission number to an infinite value; for another example, when the maximum SR transmission number is not configured, the terminal device considers that the maximum SR transmission number is an infinite value.
[0262] The following table shows a possible modification of the protocol according to the above embodiment:
[0263] The following table shows another possibility of protocol modification according to the above embodiment:
[0264] In the above example, the protocol description of "sr-TransMax" can be:
[0265] In the above embodiment, “no clearing and / or releasing operation is performed”, for example, if the network is in the network energy-saving mode, no clearing and / or releasing operation is performed; for another example, if the network is not in the network energy-saving mode, the clearing and / or releasing operation is performed.
[0266] In the above embodiment, if the network is not in the network energy saving mode, clearing and / or releasing operations are performed, for example, this may include, if the network is not in the network energy saving mode, and if the SR counter reaches a maximum value, clearing and / or releasing operations are performed.
[0267] In the above embodiment, if the network is not in the network energy saving mode, performing the clearing and / or releasing operation may further include initiating a random access procedure on the special cell; and / or canceling all pending SRs.
[0268] In the aforementioned embodiments, the “clear” operation includes: clearing any configured downlink allocation and uplink grant; and / or clearing any PUSCH resources used for semi-persistent CSI reporting.
[0269] In the aforementioned embodiments, the “release” operation includes: notifying the RRC to release the PUCCH for all serving cells; and / or notifying the RRC to release the SRS of all serving cells.
[0270] For example, if the SR counter reaches the maximum value, and if the network is not in network energy saving mode, notify RRC to release PUCCH for all serving cells, notify RRC to release SRS for all serving cells, clear any configured downlink assignments and uplink grants, clear any PUSCH resources used for semi-persistent CSI reporting, initiate a random access procedure on the special cell, and cancel all pending SRs.
[0271] For another example, if the SR counter reaches a maximum value and if the network is in a network energy saving mode, a random access procedure is initiated on the special cell and all pending SRs are canceled.
[0272] For example, if the SR counter reaches the maximum value, a random access procedure is initiated on the special cell, all pending SRs are canceled, and if the network is not in network energy saving mode, the RRC is notified to release the PUCCH for all serving cells, the SRS for all serving cells is notified to release, any configured downlink allocations and uplink grants are cleared, and any PUSCH resources used for semi-persistent CSI reporting are cleared.
[0273] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.
[0274] According to the method of the above embodiment, when the network is in network energy-saving mode, the terminal device does not trigger an SR. This prevents the pending SR from triggering a random access procedure, thereby reducing network energy consumption. Furthermore, when the network is in network energy-saving mode, the terminal device performs actions related to the pending SR in response to the network energy-saving mode. Therefore, the pending SR does not cause the terminal to release its uplink configuration.
[0275] Embodiments of the second aspect
[0276] The embodiment of the present application provides a communication method in a cell discontinuous transmission / reception scenario, which is described from the perspective of a network device, and the contents that are the same as those in the embodiment of the first aspect are not repeated.
[0277] FIG5 is a schematic diagram of a communication method according to an embodiment of the present application. As shown in FIG5 , the method includes:
[0278] 501: The network device indicates information related to network energy saving to the terminal device.
[0279] According to the above embodiment, the network device indicates information related to network energy saving to the terminal device, thereby, the terminal device may not trigger SR when the network is in network energy saving mode, or perform actions related to the network energy saving mode for the pending SR, thereby avoiding the pending SR from triggering the random access process, thereby reducing network energy consumption, or the pending SR will not cause the terminal to release the uplink configuration.
[0280] In some embodiments, the network device indicates information related to network energy saving to the terminal device. For example, the network device may indicate to the terminal device that it is in network energy saving mode. This application does not limit the specific indication method. The indication may be provided by sending indication information, or by sending configuration information, or by other means. Furthermore, this application does not limit the carrying method of the indication information or configuration information. The indication information or configuration information may be carried in various possible signaling.
[0281] In the above embodiment, the network energy-saving mode refers to at least one of the following:
[0282] The NES mode is activated.
[0283] Cell discontinuous transmission / reception (cell DTX / DRX) is configured and / or activated;
[0284] The terminal equipment is in the inactive state of cell DTX / DRX.
[0285] For example, when the network energy saving mode is "network energy saving mode is activated", the network device may further instruct the terminal device to activate the network energy saving mode (502) through at least one of RRC signaling, MAC CE signaling and DCI signaling.
[0286] For another example, when the network energy saving mode is "cell discontinuous transmission / reception configured and / or activated", the network device may further configure the cell discontinuous transmission / reception parameters through RRC signaling (503).
[0287] For another example, when the network energy saving mode is "cell discontinuous transmission / reception configured and / or activated", the network device can also indicate the activation of at least one cell discontinuous transmission / reception of the terminal device through at least one of RRC signaling, MAC CE signaling and DCI signaling (504).
[0288] For another example, when the network energy-saving mode is "the terminal device is in the inactive stage of cell discontinuous transmission / reception", the network device may also send the cell discontinuous transmission / reception configuration (505) to the terminal device, whereby the terminal device may enter the sleep or inactive time according to the cell discontinuous transmission / reception configuration, or the terminal device is not within the duration of cell discontinuous transmission / reception; or, when the cell discontinuous transmission / reception is activated, the terminal device enters the sleep or inactive time, or the terminal device is not within the duration of cell discontinuous transmission / reception.
[0289] In the aforementioned embodiments, the RRC signaling may be broadcast signaling or dedicated signaling.
[0290] In some embodiments, the network device indicates information related to network energy saving to the terminal device. For example, the network device coordinates SR configuration and cell discontinuous transmission / reception duration (cell DTX / DRX on-duration time).
[0291] In the above embodiment, the SR configuration and the duration of discontinuous transmission / reception of the cell are coordinated, for example, so that there is no valid PUCCH resource (valid PUCCH resource) during the inactive time of discontinuous transmission / reception of the cell; for another example, the valid PUCCH resource (valid PUCCH resource) can be within the active time of discontinuous transmission / reception of the cell.
[0292] In some embodiments, the network device indicates information related to network energy saving to the terminal device. For example, if the network device supports one of IAB, NTN and positioning, the network device does not indicate that it is in network energy saving mode or the network device is in network energy saving mode.
[0293] In the above embodiment, the network energy-saving mode refers to at least one of the following:
[0294] The NES mode is activated.
[0295] Cell discontinuous transmission / reception (cell DTX / DRX) is configured and / or activated;
[0296] The terminal equipment is in the inactive state of cell DTX / DRX.
[0297] The above-mentioned network energy-saving mode has been described in the embodiment of the first aspect, and its content is incorporated here and will not be repeated here.
[0298] In some embodiments, when the network device indicates that it is in the network energy saving mode, the network device does not support one of IAB, NTN, and positioning.
[0299] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.
[0300] According to the method of the above embodiment, when the network is in network energy-saving mode, the terminal device does not trigger an SR. This prevents the pending SR from triggering a random access procedure, thereby reducing network energy consumption. Furthermore, when the network is in network energy-saving mode, the terminal device performs actions related to the pending SR in response to the network energy-saving mode. Therefore, the pending SR does not cause the terminal to release its uplink configuration.
[0301] Embodiments of the third aspect

[0327] In the above embodiment, in some implementations, the processing unit 601 does not trigger a scheduling request, including:
