[0232] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0233] As shown in Figure 1a, a communication system 100 includes a terminal 101 and a network device 102. The network device may be an access network device or a core network device.

[0234] In some embodiments, the terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0237] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0238] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0239] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0240] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0241] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0242] In some embodiments, driven by the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, fifth-generation mobile communication technology (5G) has been introduced. The primary application scenarios for 5G are: enhanced mobile ultra-broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on providing users with multimedia content, services, and data, and demand for it is growing rapidly. Furthermore, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly, making a blanket statement impossible. Detailed analysis is required based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. mMTC's key features include high connection density, low data volumes, latency-insensitive services, low module costs, and a long service life.

[0243] In some embodiments, 5G terminals consume very high energy. To save energy, many terminal energy-saving technologies have been introduced, such as Connected Discontinuous Reception (C-DRX) and measurement relaxation in the connected state, which are supported by both 4G and 5G.

[0244] In some embodiments, in order to save energy for RRC_CONNECTED terminals in the radio resource control connection state, a wake-up signal (WUS) is introduced. An offset before the UE C-DRX duration (on duration) defines a period (duration) for sending the WUS signal. During the WUS duration, the WUS signal, i.e., downlink control information (DCI) DCI 2-6, is sent, which is scrambled by the low power consumption (PS-RNTI, Power Saving RNTI) to indicate whether the terminal wakes up to monitor the physical downlink control channel (PDCCH) or wakes up during the next terminal C-DRX on duration.

[0245] In some embodiments, a paging WUS is introduced to save energy for terminals in the RRC_IDLE or RRC_INACTIVE states. This WUS, also known as a paging early indication (PEI), is sent at a certain time before the paging occasion (PO) to indicate whether the terminal is monitoring paging scheduling information at that PO. The PEI is DCI 2-7, scrambled by the (PEI-RNTI, Paging Early Indication - Radio Network Temporary Identifier).

[0246] In some embodiments, as shown in Figure 1b, LP-WUR is introduced to further achieve terminal energy conservation. The base station sends a low-power wake-up signal to the terminal to wake up the terminal's main transceiver when it is asleep. The terminal's main transceiver is asleep at this time, and the LP-WUR is used to receive the LP-WUS. Upon receiving the LP-WUS, the terminal's main transceiver can be woken up to perform data transmission and reception operations. The terminal's low-power receiver consumes much less power than the terminal's main transceiver.

[0247] In the disclosed embodiments, the terminal may include a main radio (MR) and an LP-WUR (or LR, Low Power Receiver). It should be noted that in some scenarios, the MR may also be referred to as a first receiver, a first transceiver, or a main transceiver, and the LP-WUR may also be referred to as a second receiver or a second transceiver in some scenarios, without limitation herein.

[0248] In some embodiments, the power of the LP-WUR is less than the power of the MR.

[0249] In some embodiments, MR can be used for transmitting and receiving New Radio (NR) signals or channels in addition to transmitting and receiving low-power wake-up related signals or channels.

[0250] In some embodiments, the LR can be used to transmit, receive, or process low power wake-up related signals or channels.

[0251] In some embodiments, many downlink (DL) control commands from the network are based on downlink control information (DCI) or media access control (MAC) control elements (CEs). The effective time of these control commands often deviates from the time they are received. Some of this time difference is caused by UE decoding of the command and internal adjustments within the UE. For example, there is a timeline delay between the time a MAC CE command is received and the time it takes effect.

[0252] In some embodiments, with respect to a timeslot used for Physical Uplink Control Channel (PUCCH) transmission, when a UE receives an activation command (defined in [11, TS 38.321]) in a Physical Downlink Shared Channel (PDSCH) for a secondary cell ending in timeslot n, the UE applies the corresponding actions in [11, TS 38.321] no later than the minimum requirements defined in [10, TS 38.133] and no earlier than timeslot n+k, except in the following cases:

[0253] 1. Operations related to Channel State Information (CSI) reporting on the serving cell that is active in time slot n+k;

[0254] 2. Actions related to the sCellDeactivationTimer associated with the secondary cell (defined in [11, TS 38.321]) applied by the UE in time slot n+k;

[0255] 3. For actions related to serving cells where CSI reporting is not activated in time slot n+k, the UE applies the time slot in the earliest time slot n+k after the serving cell is activated.

[0256] The value of k is Slot n+m is a slot indicating a time slot for PUCCH transmission with HARQ-ACK information for PDSCH reception as described in clause 9.2.3, and is the number of slots per subframe of the SCS configuration μ used for PUCCH transmission as defined in [4, TS 38.211].

[0257] In some embodiments, the requirements in this clause shall apply to UEs configured with one downlink SCell in EN-DC, standalone NR carrier aggregation, NE-DC, or NR-DC and when one SCell is activated.

[0258] The delay with which the UE can activate a deactivated SCell depends on specified conditions.

[0259] When receiving the SCell activation command in time slot n, the UE shall be able to activate the SCell no later than time slot Send a valid CSI report and apply the actions related to the activation command of the SCell being activated, where:

[0260] T HARQ (milliseconds) is the timing between DL data transmission and acknowledgment as specified in TS 38.213[3],

[0261] T activation_time is the SCell activation delay in milliseconds.

[0262] If the SCell is known and belongs to FR1, then Tactivation_time is:

[0263] -T FirstSSB +5 ms, if the measurement period of the SCell being activated is equal to or less than 2400 ms.

[0264] -T FirstSSB_MAX +T rs +5ms, if the measurement period of the activated SCell is greater than 2400ms.

[0265] In some embodiments, after the introduction of LP-WUS, triggering certain activation commands via MAC CE after the LP-WUS can result in significant latency, as MR activation by the LP-WUS itself requires a certain transition time. Therefore, reducing this latency is a challenge that needs to be addressed. The present invention will be described below based on different commands.

[0266] Table 1: UE power consumption during state transitions

[0267] Please refer to FIG1c, which shows a schematic diagram of terminal power consumption during state transition.

[0268] In the disclosed embodiments, the terminal may include a main radio (MR) and an LP-WUR (or LR, Low Power Receiver). It should be noted that in some scenarios, the MR may also be referred to as a first-class receiver, a first-class transceiver, or a main transceiver, and the LP-WUR may also be referred to as a second-class receiver and a second-class transceiver in some scenarios, without limitation herein.

[0269] In some embodiments, the power of the LP-WUR is less than the power of the MR.

[0270] In some embodiments, MR can be used for transmitting and receiving New Radio (NR) signals or channels in addition to transmitting and receiving low-power wake-up related signals or channels.

[0271] In some embodiments, the LR can be used to transmit, receive, or process low power wake-up related signals or channels.

[0272] In some embodiments, the RLC activates or deactivates a Media Access Control (MAC) Control Element (CE).

[0273] In some embodiments, the repeated RLC activation / deactivation MAC CE is identified by a MAC subheader with an eLCID. It has a fixed size and consists of one octet, as shown in Figure 1d, where

[0274] DRB ID: This field indicates the identifier of the DRB to which the MAC CE applies. The field length is 5 bits;

[0275] RLCi: This field indicates the activation / deactivation status of the Packet Data Convergence Protocol (PDCP) repetition for Radio Link Control (RLC) entity i, where i is the ascending logical channel ID of the secondary RLC entities for the DRB, in the order of the Master Cell Group (MCG) and SCG. The RLCi field is set to 1 to indicate that the PDCP repetition for RLC entity i will be activated. The RLCi field is set to 0 to indicate that the PDCP repetition for RLC entity i will be deactivated.

[0276] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0301] In some embodiments, in response to the terminal being in a Radio Resource Control (RRC) connected state and the MR being in a deactivated state, the network device may send a first signal to the terminal.

[0302] In this way, since the first signal can both wake up the first type of transceiver and activate the SCG, it is possible to achieve rapid diversion of services and reduce the delay of service transmission.

[0505] Secondary cell group SCG;

[0506] Secondary cell SCell;

[0507] Tracking reference signal TRS transmission;

[0511] The optional implementation of step S5101 can refer to the optional implementation of steps S2101 to S2102 in Figure 2a, and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0512] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.

[0513] The following further illustrates the technical solution of the present disclosure through some exemplary embodiments. The embodiments of the present disclosure relate to a communication method, which includes:

[0514] In some embodiments, LP-WUS (corresponding to the first signal of the present disclosure) indicates SCG activation.

[0515] In some embodiments, in the LP-WUS of the activated MR (corresponding to the first type of transceiver of the present disclosure), the activation of the secondary cell group SCG is also indicated. For example, 1 bit identifies the activated SCG, and in this case, there is only one SCG configuration. The SCG ID or SCG index of the activated SCG may also be indicated, and the bitmap corresponding to the SCG ID or SCG index of the activated SCG may be indicated (for example, each bit corresponds to an SCG, and the bit value indicates whether the corresponding SCG is activated or deactivated).

[0516] In some embodiments, when the MR is deactivated in the RRC connection state, the MR is activated through LP-WUS and the SCG is activated at the same time. This can help to quickly activate the SCG, achieve rapid diversion of services or reduce the delay of service transmission.

[0517] In some embodiments, when MR is deactivated in the RRC connection state, the baseband processing of MR on the UE side can work normally, so the SCG activation indication can be received through LP-WUS first, and the baseband processing of the activation command can be performed at the same time as MR activation. When the radio frequency is ready, it can work.

[0518] In some embodiments, the timeline definition of SCG activation may be based on the time of reception of the LP-WUS or the time of full activation of the MR as a reference time.

[0519] For example, the reference time is determined based on the LP-WUS reception time and a time offset, or based on the MR activation start time and a time offset. Here, the time offset may be 0.

[0520] In some embodiments, LP-WUS indicates SCell activation and / or TRS activation.

[0521] In some embodiments, in the LP-WUS of the activated MR, the activation of the SCell or TRS (aperiodic TRS) is simultaneously indicated, for example, by a scell bitmap indication (e.g., each bit corresponds to a SCell) and / or by a bitmap indication of the activation / triggering of the TRS (e.g., each bit corresponds to a TRS).

[0522] In some embodiments, when the MR is deactivated in the RRC connection state, the MR is activated through the LP-WUS and the SCell is activated at the same time. This can facilitate the rapid activation of the SCell, achieve rapid service diversion or reduce the delay of service transmission.

[0523] In some embodiments, when MR is deactivated in the RRC connection state, the baseband processing of MR on the UE side can work normally, so the SCell activation indication can be received through LP-WUS first, and the baseband processing of the activation command can be performed at the same time as MR activation. When the radio frequency is ready, it can work.

[0524] In some embodiments, the SCell activation latency timeline definition may be based on the LP-WUS reception time or the MR full activation time as a reference time.

[0525] In some embodiments, the reference time is determined based on the LP-WUS reception time and a time offset, or based on the MR activation start time and a time offset, where the time offset may be 0.

[0526] In some embodiments, the LP-WUS indicates activation of PDCP duplication.

[0527] In some embodiments, in the LP-WUS that activates the MR, PDCP duplication activation is indicated at the same time, which can be a per DRB indication or a per Leg indication.

[0528] In some embodiments, if it is a per DRB indication, the bitmap of the DRB can be indicated, each bit represents a DRB, and the bitmap corresponds one-to-one from low bit to high bit and the DRB ID of the DRB supporting duplication from small to large.

[0529] In some embodiments, if it is a per leg indication, it can indicate the activation or deactivation of each leg of a DRB, that is, it includes a DRB information, a bitmap, and each bit in the bitmap corresponds one-to-one to each leg of the DRB, for example, according to the bitmap from low to high and the leg index from small to large.

[0530] In some embodiments, if the per-leg indication is used, all legs of all supported duplication DRBs may be included, with the DRB indexes in ascending order, and the leg indexes within the DRB in ascending order corresponding to the bitmap in descending order. The leg index of each DRB may be all leg indexes of the DRB, or all leg indexes of the leg to be activated or deactivated.

[0531] In some embodiments, if it is a per-leg indication, it includes a DRB bitmap indicating whether the legs of those DRBs are activated or deactivated. Only when the bit corresponding to the DRB is 1 (activated), the leg of the DRB will appear in the subsequent leg bitmap. The activated DRB index is ranked from small to large, and then the leg index within the DRB is ranked from small to large and the bitmap is matched one by one from high to low. The leg index of each DRB here can be all the leg indexes of the DRB, or all the leg indexes of the activated or deactivated legs can be matched one by one.

[0532] In some embodiments, when an MR is deactivated in an RRC connected state, duplication is simultaneously activated via the LP-WUS. This facilitates rapid duplication activation and reduces service transmission latency for services requiring high reliability. When an MR is deactivated in an RRC connected state, the UE's MR baseband processing can function normally. Therefore, the LP-WUS can receive the duplication activation indication first. The baseband processing can then proceed simultaneously with the MR activation, allowing the RF to be ready and ready for operation.

[0533] In some embodiments, the PDCP duplication activation delay timeline definition may be based on the LP-WUS reception time or the MR full activation time as a reference time.

[0534] In some embodiments, the reference time is determined based on the time of receiving the LP-WUS and a time offset, or based on the MR activation start time and a time offset. For example, the time offset may be 0.

[0535] In some embodiments, the LP-WUS indicates activation of SP resources.

[0536] In some embodiments, at least one of the following may be indicated via the LP-WSU:

[0537] SP ZP CSI-RS Resource Set Activation / Deactivation;

[0538] SP SRS Activation / Deactivation;

[0539] SP CSI-RS / CSI-IM Resource Set Activation / Deactivation;

[0540] PUCCH spatial relation Activation / Deactivation.

[0541] In some embodiments, the LP-WUS also needs to include at least one of the serving cell index, carrier index, BWP index, resource index, etc. where the target activation resource is located.

[0542] In some embodiments, the LP-WUS indicates activation of measurement reporting.

[0543] In some embodiments, the LP-WUS may also indicate at least one of the following:

[0544] SP CSI reporting on PUCCH Activation / Deactivation;

[0545] Aperiodic CSI Trigger State Subselection.

[0546] In some embodiments, the LP-WUS includes at least one of a serving cell index, a carrier index, a BWP index, a resource index, and a trigger state bitmap (eg, each bit corresponds to an RRC pre-configured trigger state) where the target activation reporting configuration is located.

[0547] In some embodiments, the LP-WUS may also indicate activation of measurement reporting, for example, the LP-WUS may indicate: CSI-report trigger (AP-CSI report).

[0548] In some embodiments, the LP-WUS also needs to include the serving cell index where the target activation reporting configuration is located, the BWP index, and the sequential index of the target trigger state, which is the sequential index of the activated trigger state index (RRC configuration index, MAC CE (Aperiodic CSI Trigger State Subselection) activation part) from small to large.
