It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0057] To better understand the technical solution of this application, the paging related to this application is explained below.

[0058] In NR, paging can be divided into two categories based on the source of the paging message: 5G Core Network (5GC) paging and Radio Access Network (RAN) paging.

[0059] Among them, 5GC paging originates from 5GC. When downlink data arrives at the terminal (UE) in the Radio Resource Control (RRC) idle (RRC_IDLE) state, 5GC notifies the terminal (UE) through a paging message.

[0060] Among them, RAN paging originates from gNB. When downlink data arrives at a UE in the RRC deactivated (RRC_INACTIVE) state, gNB notifies the UE to start data transmission via RAN paging message.

[0061] The final paging message is sent from the gNB to the UE via the air interface.

[0062] Paging messages are carried by the Paging Control Channel (PCCH), and the data blocks of the PCCH are carried by the Paging Channel (PCH), which in turn are carried by the Physical Downlink Shared Channel (PDSCH). Since the PDSCH is a downlink shared physical channel, it can carry not only the PCH but also the Downlink Shared Channel (DL-SCH). Therefore, before receiving a paging message (e.g., one carried on the PDSCH), the terminal needs to listen to the Physical Downlink Control Channel (PDCCH) and then determine whether the network has sent it a paging message in the current paging cycle based on whether the Paging Radio Network Temporary Identity (P-RNTI) is carried on the PDCCH.

[0063] In addition to sending paging messages, the Downlink Control Information (DCI) that schedules paging messages can also carry short messages and indications of the availability of Tracking Reference Signal (TRS) resources.

[0064] Paging messages refer to the message content sent by the base station.

[0065] A paging message carries a paging record list (PagingRecordList). The PagingRecordList contains at least one paging record (PagingRecord) and at most maxNrofPageRec pagingRecords. Each pagingRecord carries the paging identifier (ue_Identity) of the paging UE. In other words, a single paging message can indicate that at most maxNrofPageRec UEs have been paging.

[0066] There are two types of identifiers for the paged UE: one for paging UEs in an idle state, namely the Next Generation 5G Serving-Temporary Mobile Subscriber Identity (ng-5G-S-TMSI); and the other for paging UEs in an inactive state, namely the Full Inactive Radio Network Temporary Identity (full I-RNTI). The UE receiving the paging message is either in an idle or inactive state.

[0067] To better understand the technical solution of this application, the relevant SDT is explained below.

[0068] Small Data Transmission (SDT) is a process that allows non-connected UEs (such as idle and inactive UEs) to transmit data and / or signaling simultaneously without transitioning to an RRC-connected state (RRC_CONNECTED), thus avoiding excessive signaling overhead caused by RRC state transitions and RRC connection establishment.

[0069] The key feature of the small data transmission scheme is that the UE's current Data Radio Bearer (DRB) is in a suspended state, rather than a released state. Therefore, before sending a Resume Request message, the UE can restore the DRB and then use RRC signaling to piggyback the small data. At this point, it can transmit data on the DRB just like a connected terminal. This avoids state transitions and achieves efficient small data transmission with minimal signaling overhead.

[0070] For small data transmission, the data to be transmitted is carried on a dedicated traffic channel (DTCH) and multiplexed with an uplink RRC connection resumption request (RRCConnectionResumeRequest) message before transmission. Similarly, if there is a reply downlink message, it can also be carried on the DTCH and multiplexed with a downlink RRC connection release (RRCConnectionRelease) message before transmission. Because small data transmission uses DRB transmission, necessary security protections can be provided for the data, such as data encryption and integrity protection.

[0071] Small data can be transmitted on the Physical Uplink Shared Channel (PUSCH) of message 3 (Msg3) in a 4-step Random Access Channel (RACH) process, or on the PUSCH of message A (MsgA) in a 2-step RACH process, or on PUSCH resources scheduled by a configured grant (CG) configured in the RRC inactive state. Small data transmissions in 2-step and 4-step RACH processes are referred to as RACH-based small data transmissions, and small data transmissions based on PUSCH scheduled by a configured grant are referred to as CG-based small data transmissions. SDT resources can be configured for RACH and CG on the Band Width Part (BWP). RACH and CG resources of the SDT can be configured on the Normal Uplink (NUL) and / or Supplementary Uplink (SUL) carriers. When an RRC Release message with a pause indication is received, the CG resources of the SDT are only valid within the UE's primary cell (PCell). CG resources are associated with one or more Synchronization Signal Blocks (SSBs). For RACH, the network side can configure 2-step Random Access (RA) resources and / or 4-step RA resources for terminal-initiated SDTs (MO-SDT). If a terminal-terminated SDT (MT-SDT) procedure is initiated via RACH, the UE can only use RACH resources not configured for the SDT. Contention-Free Random Access (CFRA) does not support SDTs on RACH.

[0072] In an LTE system, the network (NW) carries an MT-SDT trigger message in a paging message. Subsequently, the UE initiates the SDT procedure. After receiving the UE's request message (carrying the MT-SDT reason value), the NW concatenates the RRC response message with the DRB data to form a protocol data unit, which is then sent to the UE to ultimately enable the reception of downlink services.

[0073] To better understand the technical solution of this application, the following explains the Transmission Configuration Indicator (TCI) status related to this application.

[0074] A TCI state describes the quasi-co-located (QCL) relationship between one or two downlink reference signals. The network side uses TCI states to represent the QCL source reference signal and the QCL type from which large-scale parameters can be obtained. Each TCI state can be configured with two source reference signals (RS) and a pair of QCL types.

[0075] In simple terms, QCL indicates the similarity between a source reference signal and a target reference signal. It represents the spatial channel characteristics, that is, the similarity between the characteristics of the two antenna ports of the transmitted signals (target signal and reference signal). There are four types: QCL-Type A: similarity in four aspects: {Doppler frequency shift, Doppler spread, average time delay, and time delay spread}; QCL-Type B: similarity in two aspects: {Doppler frequency shift and Doppler spread}; QCL-Type C: similarity in two aspects: {Doppler frequency shift and average time delay}; and QCL-Type D: {spatial parameters}, which is similarity in beam information.

[0076] For example, if the reference signal for the TCI configured in the PDSCH DMRS is SSB and the QCL is configured as Type D, it indicates that the transmit beam of the PDSCH DMRS is very similar to (the same as or close to) the beam of the SSB. Beams are directional, and the TCIstate relationship primarily provides a reference template for antenna transmission and reception. Based on the configured reference signal, spatial characteristics are set to facilitate better communication between the UE and the base station.

[0077] To better understand the technical solution of this application, the power control related to this application will be explained below.

[0078] For downlink channels, it's generally not called downlink power control; the base station can make the decision directly, specifying the power to be used for transmission on each channel. Therefore, it's usually called downlink power allocation.

[0079] For the uplink channel, the power is adjusted according to the distance between the UE and the base station to ensure that the power of the signal reaching the base station is similar.

[0080] Uplink power control is divided into open-loop and closed-loop depending on whether the base station and UE participate simultaneously. The closed-loop is further divided into inner loop and outer loop.

[0081] In fact, there is a process between open-loop and closed-loop. Before the UE and the base station establish a connection, the UE is not controlled by the base station. The UE adjusts its power through its own parameters, which is open-loop power. Then, after the UE and the base station establish a connection, the base station can control the UE's power, thus forming a control loop. Therefore, the power control at this stage is called closed-loop power control.

[0082] Closed loop: The transmitter controls the transmission power based on feedback information sent from the receiver.

[0083] Open-loop: No feedback information is needed from the receiver; power control is performed based on its own measurements.

[0084] Open-loop transmission does not require feedback, so it can be implemented using only the UE. The UE uses power ramping to transmit data; closed-loop transmission requires feedback from the base station (inner and outer loops), so the implementation requires the base station's participation.

[0085] The gNB adjusts the PUCCH transmit power based on the difference between the target signal-to-interference-plus-noise ratio (SINR) and the measured SINR of the received Physical Uplink Control Channel (PUCCH). The gNB calculates path loss from the Power Headroom Report (PHR) reported by the UE and then determines the target SINR of the PUCCH based on the magnitude of the path loss.

[0086] When the measured SINR is less than the target SINR range, the gNB sends a Transmission Power Control (TPC) command to the UE, instructing the UE to increase the PUSCH transmit power. The PUCCH is similar to the channels described above. However, the target SINR is set as a range parameter based on the PUCCH Block Error Ratio (BLER) requirement.

[0087] The primary purpose of power control is to reduce interference to neighboring cells caused by excessive transmission power.

[0088] PUSCH power calculation expression:

[0089]

[0090] Among them, P PUSCH,b,f,c (i,j,q d,l) represents the actual transmission power of PUSCH, which is the power at time i of PUSCH transmission in the l-th state under the j-th power control parameter set in cell c, carrier f, and uplink bandwidth b. CMAX,f,c (i) represents the maximum transmit power that the terminal can configure under cell c and carrier f, P O_PSCCH,b,f,c (j) represents the sum of several basic transmit power values ​​of PUSCH under the j-th power control parameter set, and μ represents the coefficient related to subcarrier spacing (SCS). α represents a parameter related to the number of resource blocks (RBs) occupied by the PUSCH in cell c, carrier f, and uplink bandwidth b. b,f,c (j) represents the path loss adjustment factor determined by p0-PUSCH-Alpha configured by Msg3 or RRC and based on the indication of the Scheduling Request Indication (SRI) under the j-th power control parameter. b,f,c (q d ) represents the estimated downlink path loss for cell c, carrier f, and uplink bandwidth b, Δ TF,b,f,c (i) represents the power offset adjustment value determined by the modulation and coding scheme (MCS). If the RRC parameter enables delta MCS and has a value of 1.25, the modulation value is determined by the average power value per resource element (RE) and power boosting; otherwise, it is 0. b,f,c (i,l) represents the power quantity under different power control states. It is a dynamic control quantity, and the power control value is adjusted by the TPC command.

[0091] To better understand the technical solution of this application, the DMRS related to this application is explained below.

[0092] In NR systems, the demodulation reference signal (DMRS) for the data channels (Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH)) is primarily used for data channel demodulation. For different application scenarios, the DMRS can be divided into DMRS configuration type 1 and DMRS configuration type 2. DMRS configuration type 1 supports a maximum of 4 ports for a single-symbol structure and a maximum of 8 ports for a double-symbol structure; DMRS configuration type 2 supports a maximum of 6 ports for a single-symbol structure and a maximum of 12 ports for a double-symbol structure. Furthermore, DMRS configuration type 1 supports 2 code division multiplexing (CDM) groups, while DMRS configuration type 2 supports 3 CDM groups. Ports within the same CDM group are multiplexed using a Frequency Division Orthogonal Cover Code (FD-OCC) and a Time Division Orthogonal Cover Code (TD-OCC) with a length of 2.

[0093] In addition, DMRS in NR supports the configuration of additional symbols, meaning that a DMRS port can occupy multiple symbols to achieve channel estimation gain in the time domain, such as for high-speed mobile scenarios. Depending on the number of data channel scheduling symbols, DMRS supports a maximum of 3 additional symbols, occupying a total of 4 symbols. Furthermore, the number of additional symbols supported also varies depending on whether DMRS is a single-symbol or double-symbol structure.

[0094] To support more DMRS orthogonal ports, NR has enhanced DMRS, such as doubling the number of DMRS ports and using FD-OCC sequences of length 4 to multiplex DMRS ports within the same CDM group. That is, for DMRS configuration type 1, a single-symbol structure will support a maximum of 8 ports, and a dual-symbol structure will support a maximum of 16 ports; for DMRS configuration type 2, a single-symbol structure will support a maximum of 12 ports, and a dual-symbol structure will support a maximum of 24 ports.

[0095] In addition, the number of PUSCH data streams supported per terminal has been expanded from a maximum of 4 streams to a maximum of 8 streams. In other words, the DMRS corresponding to the PUSCH transmitted by each terminal also requires a maximum of 8 ports for multiplexing.

[0096] To better understand the technical solution of this application, the default DMRS related to this application is explained below.

[0097] For situations where common channels are scheduled using fallback DCI, the NR protocol specifies some default DMRS configurations.

[0098] When PDSCH is scheduled via DCI format 1_0, or when RRC does not configure any of the higher-level parameters such as DMRS Additional Position, masLength, and DMRS Type, the terminal must assume that the PDSCH will not appear on symbols where DMRS exists (unless it is a 2-symbol PDSCH scheduled in the form of Time Domain Resource Assignment (TDRA) mapping type B). Port 1000, with a single-prefix DMRS configuration type of DMRS configuration type 1, is assumed to be configured. The remaining orthogonal DMRS ports are not associated with PDSCH transmitted to other terminals. In addition, the following conditions must be met:

[0099] For PDSCH of TDRA mapping type A and TDRA mapping type B, the terminal needs to assume dmrs-AdditionalPosition = pos2, and the maximum number of additional symbols per symbol is 2;

[0100] For a PDSCH occupying 2 symbols scheduled in the form of TDRA mapping type B, the terminal needs to assume that the PDSCH appears on a symbol where DMRS exists.

[0101] For PUSCH, if it is not scheduled by DCI format 0_1 ​​or DCI format 0_2 scrambled with the Cell Radio Network Temporary Identity (C-RNTI), Configured Scheduling Radio Network Temporary Identity (CS-RNTI), Semi-Persistent Channel State Information Radio Network Temporary Identity (SP-CSI-RNTI), or Modulation and Coding Scheme Cell Radio Network Temporary Identity (MCS-C-RNTI), and it does not correspond to a configured grant, nor does it correspond to a Type-2 random access procedure (i.e., two-step random access), then the terminal needs to assume that the configuration type of port 0 using a single preamble symbol is DMRS type 1, and that the other remaining resource elements on the DMRS symbol are... Element (RE) is not used for PUSCH transmission (unless it is a PUSCH with 2 or fewer symbols and transmission precoding is not enabled), while additional DMRS symbols can be determined according to the protocol.

[0102] When frequency hopping is not enabled, the terminal needs to assume dmrs-AdditionalPosition = pos2, and the maximum number of additional symbols is 2;

[0103] When frequency hopping is enabled, the terminal needs to assume that dmrs-AdditionalPosition = pos1, and the maximum number of additional symbols is 1.

[0104] When the PUSCH is scheduled in DCI format 0_0 based on CS-RNTI scrambling, the terminal needs to use DMRS port 0 with a single preamble symbol. The configuration type of DMRS is determined by the DMRS type (dmrs-Type) in DMRS-UplinkConfig. The remaining REs on the DMRS symbol are not used for PUSCH transmission (unless it is a PUSCH with 2 or fewer symbols and transmission precoding is not enabled). Additional symbols can be configured by dmrs-AdditionalPosition in ConfiguredGrantConfig.

For data transmission in a connectionless state before random access, to flexibly support transmission under different "features," it may be necessary to support different transmission modes (TX scheme and / or RX scheme), TCI states, beamforming, DMRS configuration, power control, scrambling codes, and other transmission-related configuration information. In this embodiment, to flexibly support transmission under different "features," the terminal obtains the transmission-related configuration information of the first channel, and the terminal performs target transmission on the first channel according to the transmission-related configuration information of the first channel.

For instance, through a specific k... SSB The value of can be used to indicate the transmission-related configuration information of the first channel, or the spare bit in the MIB can be used to indicate the transmission-related configuration information of the first channel.

[0231] For example, the larger PBCH payload in 6G contains additional bits that indicate transmission-related configuration information for the first channel.

[0232] Optionally, the synchronization sequence includes, but is not limited to, at least one of the following:

[0238] Short message indication field, short message field, frequency domain resource assignment (FDRA) field, time domain resource assignment (TDRA) field, modulation and coding field, transport block scaling field, reserved field, and specific indication field.

[0239] For example, different indicator bits in the short message indicator field correspond to different transmission-related configuration information for the first channel;

[0255] For example, different indicator bits in the reserved field correspond to different transmission-related configuration information for the first channel.

[0256] For example, different indicator bits in a specific indicator field correspond to different transmission-related configuration information for the first channel.

For instance, the transmission mode corresponding to an idle UE is mode #1; the transmission mode corresponding to an inactive UE is mode #2.

[0278] In some embodiments, the first message field is a first list field in the paging message, or the first message field is a first field in the paging record field of the paging message. The paging record field is a member of the paging record list field in the paging message.

[0279] Optionally, the first list field is a scheduling list field. Of course, the first list field can also be other fields, and this embodiment is not limited to this. In this embodiment, a scheduling list field (a newly added field compared to the paging record list field) can be added to the paging message, and the transmission-related configuration information of the first channel can be obtained based on the scheduling list field.

[0280] Optionally, the first field is a scheduling field. Of course, the first field can also be other fields, and this embodiment is not limited to this. In this embodiment, a scheduling field can be added to the paging record field in the paging message (compared to the terminal identifier and access type fields in the paging record field, the scheduling field is a newly added field), and the transmission-related configuration information of the first channel can be obtained based on the scheduling field.

[0281] Optionally, the first message field is the first list field in the paging message;

[0282] Wherein, the first list field and the paging record list field are of the same size, and the terminal identifier (ue-Identity) corresponding to each first field in the first list field corresponds one-to-one with the terminal identifier (ue-Identity) corresponding to each paging record field in the paging record list field; or, the first list field and the paging record list field are of different sizes, and each first field in the first list field has a separate terminal identifier (ue-Identity) field, that is, each first field in the first list field has its own independent terminal identifier (ue-Identity) field.

[0283] For example, taking the schedulingList field as the first list field, the schedulingList field is introduced into the paging message to indicate the transmission-related configuration information of the first channel (such as the transmission mode of the corresponding PDSCH or PUSCH). As shown below, there are two lists in the paging message: a pagingRecordList and a schedulingList.

[0284]

[0285] Optionally, the first message field is the first field in the paging record field of the paging message;

[0286] Specifically, each paging record in the PagingRecordList field of the paging message contains one of the first fields, or some paging records in the PagingRecordList field of the paging message contain the first field.

[0287] For example, taking the first field as the scheduling field, the scheduling field is introduced into the paging record to indicate the transmission-related configuration information of the first channel (such as the transmission mode of the corresponding PDSCH or PUSCH). As shown below, the paging message contains a paging record list field, and a scheduling field is introduced into some or all of the paging record fields in the paging record list field.

[0288]

[0289]

[0290] In some embodiments, the first contractual relationship includes, but is not limited to, at least one of the following:

[0291] The transmission-related configuration information of the first channel is the same as that of the second channel;

[0292] The transmission-related configuration information of the first channel is determined based on other transmission-related configuration information of the first channel;

[0293] The first channel and the second channel have the same TCI state-related information;

[0294] There is a predefined offset value between the EPRE of the first channel and the EPRE of the second channel;

[0295] The reference signal for determining the path loss of the first channel is the SSB associated with the paging channel, or the reference signal for determining the path loss of the first channel is the CSI-RS associated with the paging channel.

[0296] The method for determining the path loss value of the transmission power of the first channel is the same as the method for determining the path loss value of the transmission power of the second channel.

[0297] The method for determining the P0 value of the transmission power of the first channel is the same as the method for determining the P0 value of the transmission power of the second channel.

[0298] The method for determining the alpha value of the transmission power of the first channel is the same as the method for determining the alpha value of the transmission power of the second signal;

[0299] The power control method for the first channel is the same as the power control method for ConfiguredGrant Small Data Transmission (CG SDT) in the deactivated state;

[0300] The transmission-related configuration information of the first channel is determined based on paging-related information.

[0301] In this embodiment, the transmission-related configuration information of the first channel is the same as that of the second channel, thus the transmission-related configuration information of the first channel can be obtained based on the transmission-related configuration information of the second channel. For example, the first channel is a PDSCH or a PUSCH, and the transmission-related configuration information of the PDSCH or PUSCH is the same as that of the second channel. For instance, if the first channel is a PDSCH, the second channel can be a Paging PDSCH, and the EPRE of the Paging-based PDSCH is the same as that of legacy paging. As another example, if the first channel is a PUSCH, the second channel can be a Msg3PUSCH or a MsgA PUSCH, and the DMRS configuration of the Paging-based PUSCH is the same as that of the Msg3PUSCH, or the DMRS configuration of the Paging-based PUSCH is the same as that of the MsgA PUSCH.

[0302] In this embodiment, some transmission-related configuration information of the first channel is determined based on other transmission-related configuration information of the first channel, thereby allowing the determination of another portion of the transmission-related configuration information of the first channel based on a portion of the first channel's transmission-related configuration information. For example, the first channel is either PDSCH or PUSCH. The transmission mode-related information of PDSCH is determined based on the DMRS configuration information of PDSCH, or the transmission mode-related information of PUSCH is determined based on the DMRS configuration information of PUSCH. Specifically, the network side does not directly indicate the transmission mode of PDSCH or PUSCH, but it does indicate the DMRS configuration information of PDSCH or PUSCH. The terminal can deduce the transmission mode of PDSCH or PUSCH from the received DMRS configuration information of PDSCH or PUSCH.

[0303] In this embodiment, the first channel and the second channel have the same TCI state-related information, so the TCI state-related information of the first channel can be determined based on the TCI state-related information of the second channel. For example, the first channel is PDSCH or PUSCH, and the second channel is another idle or inactive channel. For instance, the TCI state of PDSCH is the same as that of other idle or inactive channels, or the TCI state of PUSCH is uniform with that of other idle or inactive channels, or the TCI state of PUSCH is the same as that of other idle or inactive channels, or the TCI state of PUSCH is uniform with that of other idle or inactive channels.

[0304] In this embodiment, a predefined offset value (default offset) exists between the EPRE of the first channel and the EPRE of the second channel, thereby allowing the EPRE of the first channel to be determined based on the EPRE of the second channel. For example, the EPRE of the PDSCH transmission and the paging PDSCH have a default offset 1. Another example is that the EPRE on the RE of the PDSCH carrying DMRS is the same as the EPRE on the RE of the PDSCH carrying data, or the EPRE on the RE of the PDSCH with DMRS has a default offset 2 with the RE of the PDSCH with data.

[0305] In this embodiment, the reference signal for determining the path loss of the first channel is either the SSB associated with the paging channel or the CSI-RS associated with the paging channel, thereby enabling the determination of the reference signal for the path loss of the first channel. For example, the reference signal for determining the path loss of the PUSCH transmission power is either the SSB or CSI-RS associated with paging, where the paging is the paging that schedules the PUSCH transmission.

[0306] In this embodiment, the method for determining the path loss value of the transmission power of the first channel is the same as the method for determining the path loss value of the transmission power of the second channel. Therefore, the method for determining the path loss value of the transmission power of the first channel can be obtained based on the method for determining the path loss value of the transmission power of the second channel. For example, the method for determining the path loss value of the transmission power of the PUSCH is the same as the method for determining the path loss value of the transmission power of the Msg3PUSCH, or the method for determining the path loss value of the transmission power of the PUSCH is the same as the method for determining the path loss value of the transmission power of the MsgAPUSCH.

[0307] In this embodiment, the method for determining the P0 value of the transmission power of the first channel is the same as the method for determining the P0 value of the transmission power of the second channel, thereby allowing the method for determining the P0 value of the transmission power of the first channel to be obtained based on the method for determining the P0 value of the transmission power of the second channel. For example, the method for determining the P0 value of the transmission power of PUSCH is the same as the method for determining the P0 value of the transmission power of Msg3PUSCH, or the method for determining the P0 value of the transmission power of PUSCH is the same as the method for determining the P0 value of the transmission power of MsgAPUSCH.

[0308] In this embodiment, the method for determining the alpha value of the transmission power of the first channel is the same as the method for determining the alpha value of the transmission power of the second channel, thereby allowing the method for determining the alpha value of the transmission power of the first channel to be obtained based on the method for determining the alpha value of the transmission power of the second channel. For example, the method for determining the alpha value of the transmission power of PUSCH is the same as the method for determining the alpha value of the transmission power of Msg3PUSCH, or the method for determining the alpha value of the transmission power of PUSCH is the same as the method for determining the alpha value of the transmission power of MsgAPUSCH.

[0309] In this embodiment, the power control method for the first channel is the same as the power control method for the deactivated CG SDT, thus the power control method for the first channel can be obtained based on the power control method for the deactivated CG SDT. For example, the power control method for PUSCH transmission is the same as the power control method for the deactivated CG SDT.

[0310] In this embodiment, the transmission-related configuration information of the first channel is determined based on paging-related information, thereby the transmission-related configuration information of the first channel can be determined based on paging-related information.

[0311] Optionally, the second channel includes, but is not limited to, at least one of the following:

[0312] The PDSCH carrying the paging message, the physical downlink control channel that schedules the paging message, the channel corresponding to message 3 of the random access procedure, the MsgA PUSCH of the random access procedure, the paging PDCCH or paging PDSCH that schedules the first channel, the PRACH, the channel corresponding to message 2 of the random access procedure, the channel corresponding to message 4 of the random access procedure, the channel corresponding to message B of the random access procedure, and the idle or deactivated channel other than the first channel.

[0313] Optionally, the paging-related information includes, but is not limited to, at least one of the following:

[0314] Paging associated SSB, paging associated CSI-RS, paging time domain resource information, paging frequency domain resource information, paging associated reference signal, paging associated reference signal group.

[0315] For example, specific transmission mode-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific TCI status-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific DMRS configuration information can be determined for a specific paging period or a specific paging detection occasion; or, specific beam-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific power-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific scrambling code-related information can be determined for a specific paging period or a specific paging detection occasion.

[0316] For example, the paging PDSCH corresponding to different reference signals can use a specific TCI state, or the paging PDSCH corresponding to different reference signals can use a specific transmission mode, or the paging PDSCH corresponding to different reference signals can use a specific DMRS configuration.

For instance, through a specific k... SSB The value of can be used to indicate the transmission-related configuration information of the first channel, or the spare bit in the MIB can be used to indicate the transmission-related configuration information of the first channel.

[0606] Short Message Indication Field, Short Message Field, FDRA Field, TDRA Field, Modulation and Coding Field, Transport Block Scaling Field, Reserved Field, Specific Indication Field.

[0607] For example, different indicator bits in the short message indicator field correspond to different transmission-related configuration information for the first channel;

[0645] In some embodiments, the first message field is a first list field in the paging message, or the first message field is a first field in the paging record field of the paging message.

[0646] Optionally, the first list field is a scheduling list field. Of course, the first list field can also be other fields, and this embodiment of the application is not limited to this.

[0647] Optionally, the first field is a scheduling field. Of course, the first field can also be other fields, and this embodiment of the application is not limited to this.

[0649] Wherein, the first list field has the same size as the paging record list field, and the terminal identifier (ue-Identity) corresponding to each first field in the first list field corresponds one-to-one with the terminal identifier (ue-Identity) corresponding to each paging record field in the paging record list field; or, the first list field has a different size than the paging record list field, and each first field in the first list field contains a separate terminal identifier (ue-Identity) field.

[0650] For example, taking the schedulingList field as the first list field, the schedulingList field is introduced into the paging message to indicate the transmission-related configuration information of the first channel (such as the transmission mode of the corresponding PDSCH or PUSCH). As shown below, there are two lists in the paging message: a pagingRecordList and a schedulingList.

[0651]

[0653] Specifically, each paging record in the PagingRecordList field of the paging message contains one of the first fields, or some paging records in the PagingRecordList field of the paging message contain the first field.

[0654] For example, taking the first field as the scheduling field, the scheduling field is introduced into the paging record to indicate the transmission-related configuration information of the first channel (such as the transmission mode of the corresponding PDSCH or PUSCH). As shown below, the paging message contains a paging record list field, and a scheduling field is introduced into some or all of the paging record fields in the paging record list field.

[0655]

[0656]

[0657] Optionally, the first agreement relationship includes, but is not limited to, at least one of the following:

[0658] The transmission-related configuration information of the first channel is the same as that of the second channel;

[0659] The transmission-related configuration information of the first channel is determined based on other transmission-related configuration information of the first channel;

[0660] The first channel and the second channel have the same TCI state-related information;

[0661] There is a predefined offset value between the EPRE of the first channel and the EPRE of the second channel;

[0662] The reference signal for determining the path loss of the first channel is the SSB associated with the paging channel, or the reference signal for determining the path loss of the first channel is the CSI-RS associated with the paging channel.

[0663] The method for determining the path loss value of the transmission power of the first channel is the same as the method for determining the path loss value of the transmission power of the second channel.

[0664] The method for determining the P0 value of the transmission power of the first channel is the same as the method for determining the P0 value of the transmission power of the second channel.

[0665] The method for determining the alpha value of the transmission power of the first channel is the same as the method for determining the alpha value of the transmission power of the second signal;

[0666] The power control method for the first channel is the same as the power control method for the CG SDT in the deactivated state;

[0667] The transmission-related configuration information of the first channel is determined based on paging-related information.

[0668] In this embodiment, the transmission-related configuration information of the first channel is the same as that of the second channel, thus the transmission-related configuration information of the first channel can be obtained based on the transmission-related configuration information of the second channel. For example, the first channel is a PDSCH or PUSCH, and the transmission-related configuration information of the PDSCH or PUSCH is the same as that of the second channel. For instance, if the first channel is a PDSCH, the second channel can be a Paging PDSCH, and the EPRE of the Paging-based PDSCH is the same as that of legacy paging. As another example, if the first channel is a PUSCH, the second channel can be a Msg3PUSCH or a MsgAPUSCH, and the DMRS configuration of the Paging-based PUSCH is the same as that of the Msg3PUSCH, or the DMRS configuration of the Paging-based PUSCH is the same as that of the MsgA PUSCH.

[0669] In this embodiment, some transmission-related configuration information of the first channel is determined based on other transmission-related configuration information of the first channel, thereby allowing the determination of another portion of the transmission-related configuration information of the first channel based on a portion of the first channel's transmission-related configuration information. For example, the first channel is either PDSCH or PUSCH. The transmission mode-related information of PDSCH is determined based on the DMRS configuration information of PDSCH, or the transmission mode-related information of PUSCH is determined based on the DMRS configuration information of PUSCH. Specifically, the network side does not directly indicate the transmission mode of PDSCH or PUSCH, but it does indicate the DMRS configuration information of PDSCH or PUSCH. The terminal can deduce the transmission mode of PDSCH or PUSCH from the received DMRS configuration information of PDSCH or PUSCH.

[0670] In this embodiment, the first channel and the second channel have the same TCI state-related information, so the TCI state-related information of the first channel can be determined based on the TCI state-related information of the second channel. For example, the first channel is PDSCH or PUSCH, and the second channel is another idle or inactive channel. For instance, the TCI state of PDSCH is the same as that of other idle or inactive channels, or the TCI state of PUSCH is uniform with that of other idle or inactive channels, or the TCI state of PUSCH is the same as that of other idle or inactive channels, or the TCI state of PUSCH is uniform with that of other idle or inactive channels.

[0671] In this embodiment, a predefined offset value (default offset) exists between the EPRE of the first channel and the EPRE of the second channel, thereby allowing the EPRE of the first channel to be determined based on the EPRE of the second channel. For example, the EPRE of the PDSCH transmission and the paging PDSCH have a default offset 1. Another example is that the EPRE on the RE of the PDSCH carrying DMRS is the same as the EPRE on the RE of the PDSCH carrying data, or the EPRE on the RE of the PDSCH with DMRS has a default offset 2 with the RE of the PDSCH with data.

[0672] In this embodiment, the reference signal for determining the path loss of the first channel is either the SSB associated with the paging channel or the CSI-RS associated with the paging channel, thereby enabling the determination of the reference signal for the path loss of the first channel. For example, the reference signal for determining the path loss of the PUSCH transmission power is either the SSB or CSI-RS associated with paging, where the paging is the paging that schedules the PUSCH transmission.

[0673] In this embodiment, the method for determining the path loss value of the transmission power of the first channel is the same as the method for determining the path loss value of the transmission power of the second channel. Therefore, the method for determining the path loss value of the transmission power of the first channel can be obtained based on the method for determining the path loss value of the transmission power of the second channel. For example, the method for determining the path loss value of the transmission power of the PUSCH is the same as the method for determining the path loss value of the transmission power of the Msg3PUSCH, or the method for determining the path loss value of the transmission power of the PUSCH is the same as the method for determining the path loss value of the transmission power of the MsgAPUSCH.

[0674] In this embodiment, the method for determining the P0 value of the transmission power of the first channel is the same as the method for determining the P0 value of the transmission power of the second channel, thereby allowing the method for determining the P0 value of the transmission power of the first channel to be obtained based on the method for determining the P0 value of the transmission power of the second channel. For example, the method for determining the P0 value of the transmission power of PUSCH is the same as the method for determining the P0 value of the transmission power of Msg3PUSCH, or the method for determining the P0 value of the transmission power of PUSCH is the same as the method for determining the P0 value of the transmission power of MsgAPUSCH.

[0675] In this embodiment, the method for determining the alpha value of the transmission power of the first channel is the same as the method for determining the alpha value of the transmission power of the second channel, thereby allowing the method for determining the alpha value of the transmission power of the first channel to be obtained based on the method for determining the alpha value of the transmission power of the second channel. For example, the method for determining the alpha value of the transmission power of the PUSCH is the same as the method for determining the alpha value of the transmission power of the Msg3PUSCH, or the method for determining the alpha value of the transmission power of the PUSCH is the same as the method for determining the alpha value of the transmission power of the MsgAPUSCH.

[0676] In this embodiment, the power control method for the first channel is the same as the power control method for the deactivated CG SDT, thus the power control method for the first channel can be obtained based on the power control method for the deactivated CG SDT. For example, the power control method for PUSCH transmission is the same as the power control method for the deactivated CG SDT.

[0677] In this embodiment, the transmission-related configuration information of the first channel is determined based on paging-related information, thereby the transmission-related configuration information of the first channel can be determined based on paging-related information.

[0678] Optionally, the second channel includes, but is not limited to, at least one of the following:

[0679] The PDSCH carrying the paging message, the physical downlink control channel that schedules the paging message, the channel corresponding to message 3 of the random access procedure, the MsgA PUSCH of the random access procedure, the paging PDCCH or paging PDSCH that schedules the first channel, the PRACH, the channel corresponding to message 2 of the random access procedure, the channel corresponding to message 4 of the random access procedure, the channel corresponding to message B of the random access procedure, and the idle or deactivated channel other than the first channel.

[0680] Optionally, the paging-related information includes, but is not limited to, at least one of the following:

[0681] Paging associated SSB, paging associated CSI-RS, paging time domain resource information, paging frequency domain resource information, paging associated reference signal, paging associated reference signal group.

[0682] For example, specific transmission mode-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific TCI status-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific DMRS configuration information can be determined for a specific paging period or a specific paging detection occasion; or, specific beam-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific power-related information can be determined for a specific paging period or a specific paging detection occasion; or, specific scrambling code-related information can be determined for a specific paging period or a specific paging detection occasion.

[0683] For example, the paging PDSCH corresponding to different reference signals can use a specific TCI state, or the paging PDSCH corresponding to different reference signals can use a specific transmission mode, or the paging PDSCH corresponding to different reference signals can use a specific DMRS configuration.

[0684] Example 3 details the technical solution of this application using the terminal's ability to report transmission-related configuration information as an example. Optionally, the transmission-related configuration information includes at least one of the following: transmission mode-related information, TCI status-related information, beam-related information, DMRS configuration information, power-related information, and scrambling code-related information.

This application does not limit this.
