[0050] In this application, the paging message can be at least one of the following: paging control information (e.g., a control channel that schedules the paging data channel), paging information (e.g., a paging data channel), a data channel scheduled by the paging control information (e.g., a Physical Downlink Shared Channel (PDSCH) channel additionally scheduled by the paging Downlink Control Information (DCI)), or an additional data channel scheduled by the paging data channel (e.g., a PDSCH channel further scheduled by the paging PDSCH). The content of the paging message can be the paging message itself or a short message.

[0051] In this application, the Synchronization Signal and Physical Broadcast Channel (PBCH) block (SSB) can be any module that includes at least one of a synchronization signal, a broadcast signal, a Physical Broadcast Channel (PBCH), and other system message downlink broadcast channels. Optionally, the SSB may also include a control channel, a set of control resources, or a control channel search space corresponding to at least one of the synchronization signal, broadcast signal, PBCH, and other system message downlink broadcast channels.

[0052] In this application, the communication mode can be a specific operating mode of a terminal or network-side device. A mode can also be described as a working module, module, mode, communication device, transmission mode, transmit mode (Tx mode), receive mode, power class, a specific associated reference signal, or a specific set of corresponding resources. The activation or support of the communication mode includes activation / deactivation of only one mode (e.g., high-power mode), or activation / deactivation of at least two modes simultaneously. The communication mode (e.g., low-power (LP) or high-power (HP) operating mode) can also refer to a communication mode that differs significantly in one or more aspects such as frequency band / bandwidth / carrier, rate, transmission waveform, coverage level, sleep / DTX / DRX time, paging period, SSB / SIB period, whether resources are on demand, and SSB / System Information Block (SIB) type. It can refer to different operating parameters used by the same communication hardware module, or multiple different communication modules. Multiple communication modules can have at least one independent component at the physical layer, such as an RF front-end, antenna, or baseband; however, it is also possible for all devices to be completely independent.

[0053] In this application, an "on demand" signal refers to a signal that requires activation or a request before transmission can occur. The signal can also be a signal transmission resource, such as SSB, SIB1, other system information, Paging, PRACH, SRS, CSI-RS, PRS, TRS, DMRS, or PUSCH (e.g., a contention-based PUSCH resource).

[0054] In this application, Cell DTX / DRX may refer to Cell DTX alone, Cell DRX alone, or both Cell DTX and Cell DRX.

[0055] In this application, the Cell DTX / DRX non-active period can also be described as the off-duration, or as the period during which signal / channel reception or transmission is not permitted, or as the period during which signal / channel reception or transmission is not permitted under certain conditions.

[0056] In this application, the Cell DTX / DRX active period can also be described as the on-duration, or the time period during which signal / channel reception or transmission is permitted, or the time period during which signal / channel reception or transmission is permitted under certain conditions.

[0057] In this application, the Cell DTX / DRX inactivation period includes one of the following: the Cell DTX inactivation period; the Cell DRX inactivation period; or the Cell DTX and Cell DRX inactivation periods. The Cell DTX and Cell DRX inactivation periods represent the intersection of the Cell DTX and Cell DRX inactivation periods.

[0058] It should be noted that in this application, the inactivation period of Cell DTX / DRX, the inactivation period of Cell DTX and / or DRX, the inactivation period of Cell DTX and / or Cell DRX, the inactivation period of Cell DTX and / or Cell DRX, the inactivation period of Cell DTX and / or Cell DRX, and the inactivation period of Cell DTX and / or Cell DRX all have the same meaning.

[0059] In this application, the Cell DTX / DRX activation period includes one of the following: the Cell DTX activation period; the Cell DRX activation period; or the activation periods of both Cell DTX and Cell DRX. The Cell DTX and Cell DRX activation periods represent the intersection of the Cell DTX activation period and the Cell DRX activation period.

[0060] It should be noted that in this application, the activation period of Cell DTX / DRX, the activation period of Cell DTX and / or DRX, the activation period of Cell DTX and / or Cell DRX, the activation period of Cell DTX and / or Cell DRX, the activation period of Cell DTX and / or Cell DRX, and the activation period of Cell DTX and / or Cell DRX all have the same meaning.

[0061] In this application, the Layer 1 / L2 triggered mobility (LTM) process can also be described as a physical layer and / or Layer 2 triggered mobility process. The mobility process can be a handover or selection process of at least one of the following: beam or beam group, cell or cell group, carrier or carrier group, band or band group, associated reference signal or associated reference signal group, feature or feature combination.

[0064] The feature combination can be a combination of several features in the above examples.

[0065] To reduce data transmission latency, data transmission in idle / inactive states needs to be supported. Data transmission can be based on RACH, on PUSCH resources configured with a configured grant, or on small data transmissions based on paging or paging scheduling.

[0066] To reduce switching time, it is necessary to support LTM and RACH less processes, and to perform some synchronization in advance or directly transmit PUSCH if no synchronization is required.

[0067] To conserve network energy, downlink signals can be turned off or disabled by default, and transmission can be triggered on demand based on requests. In this case, the correlation between downlink signals and related request signals (e.g., WUS) needs to be considered.

[0068] Figure 2 This is a flowchart illustrating the communication method provided in an embodiment of this application. Figure 2 As shown, the communication method includes: step 200.

[0069] In the embodiments of this application, the communication device may be a terminal or a network-side device.

[0070] Step 200: The communication device performs the first operation according to the cell discontinuous transmission DTX configuration and / or cell discontinuous reception DRX configuration;

[0071] The first operation includes at least one of the following:

[0072] Determine the validity of the transmission resources of the first object, and / or determine whether the transmission resources of the first object are used for transmission, wherein the first object includes at least one of a signal and a channel;

[0073] Determine the available resources for repeated transmission or transmission across time units of the first object, and / or determine whether the available resources for repeated transmission or transmission across time units of the first object are used for transmission;

[0074] Determine the validity of the transmission resources of the second object, and / or determine whether the transmission resources of the second object are used for transmission, wherein the second object includes a configured grant Physical Uplink Shared Channel (CGPUSCH) and / or a wake-up signal WUS;

[0075] Determine the effectiveness of timing advance (TA);

[0076] Determine the type of the first data transmission, or determine whether to perform the first data transmission, or determine both the type of the first data transmission and whether to perform the first data transmission of that type.

[0077] This application proposes the following methods in a Cell DTX / DRX scenario: determining the transmission resources of a first object, determining whether the transmission resources of the first object are used for transmission, determining the available resources for repeated transmission or cross-time unit transmission of the first object, determining whether repeated transmission or cross-time unit transmission of the first object is used for transmission, determining the transmission resources of a second object, determining whether the transmission resources of the second object are used for transmission, determining the validity of advance timing (TA), determining the type of first data transmission, and determining whether to execute the first data transmission.

[0078] Optionally, the configuration of cell DTX and / or cell DRX may include one or more of the following information: cycle length, start time, stop time, start duration, or stop duration. Here, start time refers to the beginning of the active period (i.e., the active period) within the cell DTX / DRX cycle, stop time is the beginning of the inactive period (i.e., the inactive period) within the cell DTX / DRX cycle, start duration is the duration of the active period, and stop duration is the duration of the inactive period.

[0079] Optionally, based on the configuration of the cell's DTX and / or the configuration of the cell's DRX, at least one of the following can be determined:

[0080] During the activation period of the community DTX;

[0081] During the activation period of the community's DRX;

[0082] During the activation period of cell DTX or cell DRX;

[0083] During the activation of cell DTX and cell DRX;

[0084] During the inactive period of the cell DTX;

[0085] During the inactive period of the cell's DRX;

[0086] During the inactive period of cell DTX or cell DRX;

[0087] During the inactivity of cell DTX and cell DRX.

[0088] Optionally, the first operation is to determine the validity of the transmission resources of the first object, and / or to determine whether the transmission resources of the first object are used for transmission.

[0089] Optionally, the first object includes at least one of a signal and a channel.

[0090] Optionally, the first object includes at least one of the following:

[0091] a) A data transmission channel used for small data transmissions;

[0092] For example, the CGPUSCH channel used for small data transmission in specific UE states (e.g., RRC idle / inactive state).

[0093] b) Data transmission channel triggered by paging;

[0094] c) The data transmission channel indicated by the paging PDCCH;

[0095] d) Physical uplink shared channel (PUSCH) during mobility LTM processes triggered by Layer 1 / Layer 2;

[0096] e) PUSCH during RACH-less handover processes, such as CGPUSCH;

[0097] f) Based on the requested signal or channel, e.g., on demand SSB;

[0098] g) Request signals, such as the WUS signal.

[0099] The transmission method of the first object includes one of the following: single transmission of the first object; repeated transmission of the first object; retransmission of the first object.

[0100] The transmission resources of the first object refer to the time-domain resources and / or frequency-domain resources corresponding to the corresponding signal or channel during transmission / reception.

[0101] Determining the validity of the transmission resources of the first object includes determining whether the transmission resources of the first object are valid or invalid. It should be noted that a valid resource does not necessarily mean that the resource can be used for actual transmission.

[0102] Whether the transmission resources of the first object are used for transmission can be understood as whether the transmission resources of the first object are used for actual sending and / or receiving, or whether the sending and / or receiving of the first object is performed on the transmission resources of the first object.

[0103] Understandably, the validity of the transmission resources of the first object and whether the transmission resources of the first object are used for actual transmission need to take into account the configuration of Cell DTX and / or Cell DRX.

[0104] Optionally, the first operation determines the available resources for repeated transmission or transmission across time units of the first object, and / or determines whether the available resources for repeated transmission or transmission across time units of the first object are used for transmission.

[0105] For a specific first object, the transmission might be a repeated transfer based on available time units or a scheduled transmission spanning multiple time units. For example, repeated transfers of PUSCH during LTM can be based on available slots. In this case, the available slots need to be determined. As another example, PUSCH can be scheduled based on multiple slots, in which case these multiple slots need to be available slots. Determining the available time units requires considering the configuration of Cell DTX and / or Cell DRX.

[0106] In the embodiments of this application, the time unit is a period of time in the time domain. For example, communication between the terminal and the network-side device in the time domain can be granular with time units as the unit of measurement. For example, the time unit can be a time slot, symbol, subframe, radio frame, micro-time slot, mini-time slot, etc., and there is no limitation thereto.

[0107] Optionally, the first operation is to determine the validity of the transmission resources of the second object, and / or to determine whether the transmission resources of the second object are used for transmission, wherein the second object includes a configured authorized physical uplink shared channel CG PUSCH and / or a wake-up signal WUS.

[0108] For SSB transmission under Cell DTX, it is also necessary to consider the actual valid or transmitted SSBs in this case to determine the corresponding data transmission channel. For example, the validity of CGPUSCH resources in LTM process, RACH-less process or data transmission process, or the validity of WUS resources in signal request process, as well as the correlation between SSB and CG PUSCH resources, or the correlation between SSB and WUS resources.

[0109] Optionally, the first operation is to determine the validity of the timing advance TA.

[0110] For uplink transmissions in small data transfer processes, such as LTM, RACH-less, or WUS, the validity of the TA (Transmission Target) needs to be assessed. This requires considering whether the transmission of relevant measurement signals is affected by Cell DTX / DRX to ensure the accuracy of TA acquisition.

[0111] Optionally, the first operation is to determine the type of the first data transmission, or to determine whether to perform the first data transmission, or to determine both the type of the first data transmission and whether to perform the first data transmission of that type.

[0112] When multiple data transmission types are supported, such as RACH-based data transmission in RRC idle / inactive states (e.g., in Msg3 PUSCH or msgAPUSCH), CGPUSCH-based data transmission, or paging-based data transmission, it is necessary to consider which data transmission type to choose and / or whether to perform data transmission at all. This may require measuring the corresponding signals, and such measurements must take into account the impact of Cell DTX / DRX.

[0113] In the Cell DTX / DRX scenario, this application provides methods for determining the transmission resources of a first object, determining whether the transmission resources of the first object are used for transmission, determining the available resources for repeated transmission or cross-time unit transmission of the first object, determining whether repeated transmission or cross-time unit transmission of the first object is used for transmission, determining the transmission resources of a second object, determining whether the transmission resources of the second object are used for transmission, determining the validity of advance timing (TA), determining the type of the first data transmission, and determining whether to execute the first data transmission. By considering the impact of cell DTX and / or cell DRX configuration on communication resources and related communication parameters in the corresponding communication process, network resource and energy efficiency can be improved, achieving energy saving.

[0114] In some embodiments, determining the validity of the transmission resources of the first object, and / or determining whether the transmission resources of the first object are used for transmission, includes at least one of the following:

[0115] During the inactivity period of the cell DRX, the transmission resources of the first object are invalid;

[0116] During the inactivity period of the cell DRX, the transmission resources of the first object are not used for sending and / or receiving;

[0117] During the inactivity period of cell DTX, the transmission resources of the first object are invalid;

[0118] During the inactivity period of cell DTX, the transmission resources of the first object are not used for sending and / or receiving;

[0119] During the period when cell DTX is inactive and cell DRX is inactive, the transmission resources of the first object are invalid;

[0120] During the period when cell DTX is inactive and cell DRX is inactive, the transmission resources of the first object are not used for sending and / or receiving;

[0121] It should be noted that the inactivity period of cell DTX and cell DRX represents the intersection of the inactivity periods of cell DTX and cell DRX.

[0122] During the inactive period of cell DTX or cell DRX, the transmission resources of the first object are invalid;

[0123] During the inactive period of cell DTX or cell DRX, the transmission resources of the first object are not used for sending and / or receiving;

[0124] For subband full-duplex (SBFD) of Frequency Division Duplexing (FDD) or subband full-duplex (TDD) of Time Division Duplexing (TDD), during the inactive period of cell DTX, the transmission resources of the first object can be used for uplink transmission and / or reception on the uplink UL or UL subband.

[0125] In other words, for full-duplex subbands of FDD or full-duplex subbands of TDD, uplink transmission and / or reception can continue during the inactive period of cell DTX in UL or UL subband.

[0126] For FDD subband full-duplex or TDD subband full-duplex scenarios, during the inactive period of cell DRX, the transmission resources of the first object can be used for downlink DL or DL ​​subband downlink transmission and / or reception.

[0127] In other words, for full-duplex subbands of FDD or full-duplex subbands of TDD, downlink transmission and / or reception can continue during the inactive period of cell DRX.

[0128] For FDD subband full-duplex or TDD subband full-duplex scenarios, during the period when cell DTX is inactive and cell DRX is active, the transmission resources of the first object can be used for uplink transmission and / or reception on UL or UL subband.

[0129] In other words, for full-duplex subbands of FDD or full-duplex subbands of TDD, uplink transmission and / or reception can continue during the period when cell DTX is inactive and cell DRX is active.

[0130] For FDD subband full-duplex or TDD subband full-duplex scenarios, during the period when cell DRX is inactive and cell DTX is active, the transmission resources of the first object can be used for downlink transmission and / or reception on DL or DL ​​subband.

[0131] In other words, for full-duplex subbands of FDD or full-duplex subbands of TDD, downlink transmission and / or reception can continue during the period when cell DRX is inactive and cell DTX is active.

[0132] In FDD, subband full-duplex means dividing the frequency band into multiple subbands, allowing some subbands to be used for uplink and others for downlink within the same frequency band, and transmitting simultaneously.

[0133] TDD subband full-duplex refers to dividing a single carrier into subbands, so that part of the subband is used for uplink and the other part for downlink, and bidirectional transmission is achieved within the same time window.

[0134] This application proposes a method for determining whether the transmission resources of a first object are useful under different Cell DTX / DRX configurations, and a method for determining whether the transmission resources of a first object are used for transmission, which can improve network resource and energy efficiency and achieve network energy saving.

[0135] In some embodiments, determining the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, includes:

[0136] The validity of the transmission resources of the first object and / or whether the transmission resources of the first object are used for transmission are determined based on at least one of the following:

[0137] Network configuration;

[0138] The third object in which the transmission of the first object is located or the corresponding third object includes at least one of cell, frequency band, carrier, transmit / receive point (TRP), sub-band, and frequency range;

[0139] The reference signal or reference signal group associated with the transmission of the first object;

[0140] The combination of characteristics to which the transmission of the first object belongs or is associated;

[0141] The network slice to which or associated the transmission of the first object belongs;

[0142] The first information of the first object, which is related to the repeated transmission or cross-time unit transmission of the first object;

[0143] The second information of the first object, which is related to the retransmission of the first object;

[0144] The third information of the SSB associated with the first object.

[0145] In one implementation, the validity of the transmission resources of the first object is determined based on the network configuration, and / or it is determined whether the transmission resources of the first object are used for transmission.

[0146] For example, during the non-active period of Cell DRX, whether the transport resources of the first object are invalid can be configured by the network.

[0147] In one implementation, the validity of the transmission resources of the first object is determined based on at least one of the cell, frequency band, carrier, transmit / receive point (TRP), sub-band, and frequency range in which the transmission of the first object is located or corresponding, and / or it is determined whether the transmission resources of the first object are used for transmission.

[0148] For example, for the first cell, during the non-active period of Cell DRX, the transmission resources of the first object are invalid, while they are valid for other cells.

[0149] In one implementation, the validity of the transmission resources of the first object is determined based on the reference signal or group of reference signals associated with the transmission of the first object, and / or it is determined whether the transmission resources of the first object are used for transmission.

[0150] For example, for a first object associated with a specific SSB or group of SSBs, the transport resources for that first object are valid during the non-active period of Cell DRX. However, for a first object associated with a different group of SSBs, the transport resources for that first object are invalid during the non-active period of Cell DRX.

[0151] In one implementation, the validity of the transmission resources of the first object is determined based on the feature combination to which the transmission of the first object belongs or is associated, and / or it is determined whether the transmission resources of the first object are used for transmission.

[0152] For example, for CG PUSCH transmissions used for small data transfers, the transmission resources during the Cell DRX inactivity period are valid or available for transmission for CG PUSCH transmissions corresponding to a specific feature combination. However, for CG PUSCH transmissions corresponding to a different feature combination, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0153] In one implementation, the validity of the transmission resources of the first object is determined based on the network slice to which the transmission of the first object belongs or is associated, and / or it is determined whether the transmission resources of the first object are used for transmission.

[0154] Network slicing is a differentiated approach to handling different services within a network. For example, different slices can be configured for services such as eMBB, URLLC, or eMTC, and different slices can correspond to different physical resources.

[0155] For example, for CG PUSCH transmissions used for small data transfers, the transmission resources during the Cell DRX inactivity period are valid or available for transmission when the CG PUSCH transmission corresponds to a specific network slice. However, for CG PUSCH transmissions corresponding to another network slice, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0156] In one implementation, the validity of the transmission resources of the first object is determined based on the first information of the first object, and / or it is determined whether the transmission resources of the first object are used for transmission, wherein the first information relates to the repeated transmission or cross-time unit transmission of the first object.

[0157] Optionally, the first information of the first object includes at least one of the following:

[0158] The transmission of the first object is a repeated transmission, or the transmission of the first object is not a repeated transmission;

[0159] The transmission of the first object is the Xth transmission or the previous Xth transmission of the first object repeated transmission, or the transmission of the first object is not the Xth transmission or the previous Xth transmission of the first object repeated transmission, where X is a positive integer greater than or equal to 1.

[0160] The transmission of the first object is based on repeated transmissions of available time units, or on repeated transmissions of physical time units;

[0161] The transmission of the first object is either a time-unit transmission or not a time-unit transmission.

[0162] For example, for CG PUSCH transmissions used for small data transfers, if it is not a repeated transmission, the transmission resources during the Cell DRX inactivity period are valid or available for transmission. However, for repeated CG PUSCH transmissions, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0163] For example, for CG PUSCH transmissions used for small data transfers, if it is the first transmission in a repeated transmission, the transmission resources during the Cell DRX inactivity period are valid or available for transmission. However, for subsequent transmissions in a repeated CG PUSCH transmission, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0164] For example, for CG PUSCH transmissions used for small data transfers, if it's one of the first two repeated transmissions, the transmission resources during the Cell DRX inactivity period are valid or available for transmission. However, for CG PUSCH transmissions other than the first two repeated transmissions, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0165] For example, for CG PUSCH transmissions used for small data transfers, if it is a repeated transmission based on an available slot, the transmission resources during the Cell DRX inactivity period are valid or available for transmission. However, for repeated CG PUSCH transmissions based on physical slots, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0166] For example, for CG PUSCH transmissions used for small data transfers, if the transmission is scheduled across time units, the transmission resources during the CellDRX inactive period are valid or available for transmission; if the transmission is not scheduled across time units, the transmission resources during the Cell DRX inactive period are invalid or unavailable for transmission.

[0167] In one implementation, the validity of the transmission resources of the first object is determined based on the second information of the first object, and / or it is determined whether the transmission resources of the first object are used for transmission, wherein the second information is related to the retransmission of the first object.

[0168] For example, for CG PUSCH transmissions used for small data transfers, if it is not a retransmission, the transmission resources during the Cell DRX inactivity period are valid or available for transmission. However, for CG PUSCH retransmissions, the transmission resources during the Cell DRX inactivity period are invalid or unavailable for transmission.

[0169] In one implementation, the validity of the transmission resources of the first object is determined based on the third information of the SSB associated with the first object, and / or it is determined whether the transmission resources of the first object are used for transmission.

[0170] Optionally, the third information of the SSB associated with the first object includes at least one of the following:

[0171] The type of the synchronization signal and physical broadcast channel block (SSB) associated with the first object;

[0172] The transmission method of the SSB associated with the first object;

[0173] The SSB associated with the first object is on the synchronization grid, or it is not on the synchronization grid;

[0174] The SSB associated with the first object is either the SSB that defines the cell, or it is not the SSB that defines the cell;

[0175] The information carried by the SSB associated with the first object;

[0176] The size of the information carried by the SSB associated with the first object.

[0177] In one implementation, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the type of the SSB associated with the first object.

[0178] The types of SSBs include at least one of the following: cycle size, bandwidth size, and whether it is a Level 1 SSB or a Level 2 SSB.

[0179] For example, for a long-period SSB (e.g., 160ms), the first associated object is considered valid during the Cell DTX / DRX inactivity period because the SSB is already sparse at this time. However, for a short-period SSB, the first associated object is considered invalid during the Cell DTX / DRX inactivity period because the first associated object of other SSBs can be measured during this time.

[0180] For example, for a small-bandwidth SSB (e.g., 3MHz or 12PRB), the first associated object is considered valid during Cell DTX / DRX inactivity, as reception for each SSB is important during this period, and the transmission performance of a single SSB is relatively poor. However, for a large-bandwidth SSB, the first associated object is considered invalid during Cell DTX / DRX inactivity, because the first associated objects of other SSBs can be measured during this time.

[0181] In one implementation, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the transmission method of the SSB associated with the first object.

[0182] Optionally, the transmission method of SSB includes one of the following: active SSB, inactive SSB, trigger-based transmission, request-based transmission, or periodic transmission.

[0183] For example, for an inactive on-demand SSB, its associated first signal is considered invalid during the inactive period of cell DTX and / or cell DRX.

[0184] In one implementation, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on whether the SSB associated with the first object is on the synchronization grid.

[0185] For example, transmission resources associated with a first object on a sync raster are considered valid during the inactivity of cell DTX and / or cell DRX; otherwise, transmission resources associated with a first object not on a sync raster are considered invalid during the inactivity of cell DTX and / or cell DRX.

[0186] It should be noted that the inactive period of cell DTX and / or cell DRX includes one of the following: inactive period of cell DTX, inactive period of cell DRX, inactive period of cell DTX and inactive period of cell DRX, which can be abbreviated as Cell DTX / DRX non-active period.

[0187] In one implementation, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on whether the SSB associated with the first object is the SSB of the defined cell.

[0188] For example, the transmission resources of the first object associated with the SSB of the defined cell are considered valid during the inactivity of the cell DTX and / or cell DRX; otherwise, the transmission resources of the first object associated with the SSB of the undefined cell are considered invalid during the inactivity of the cell DTX and / or cell DRX.

[0189] In one implementation, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the information carried by the SSB.

[0190] Optionally, the information carried by the SSB associated with the first object includes at least one of the following:

[0191] The sequence of SSBs associated with the first object;

[0192] The waveform of the SSB associated with the first object;

[0193] The modulation and coding scheme (MCS) of the SSB associated with the first object;

[0194] The first bit or field carried by the SSB associated with the first object;

[0195] The second bit or field carried by the MIB in the SSB associated with the first object;

[0196] The PBCH payload size of the SSB associated with the first object.

[0197] Optionally, the sequence of the SSB associated with the first object includes at least one of the following: the primary synchronization signal PSS sequence; a scrambled sequence of the PSS sequence; the secondary synchronization signal SSS sequence; a scrambled sequence of the SSS sequence; the demodulation reference signal DMRS sequence of the PBCH; a scrambled sequence of the DMRS sequence of the PBCH; and a scrambled sequence of the PBCH.

[0198] For example, when an SSB uses sequence A as its PSS / SSS / DMRS, the transport resources of its associated first object are valid during Cell DTX / DRX non-active; when an SSB uses sequence B as its PSS / SSS / DMRS, the transport resources of its associated first object are invalid during Cell DTX / DRX non-active.

[0199] Optionally, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the waveform of the SSB associated with the first object.

[0200] For example, when an SSB uses waveform A to send information, the transmission resources of its associated first object are valid during Cell DTX / DRX non-active; when an SSB uses waveform B to send information, the transmission resources of its associated first object are invalid during Cell DTX / DRX non-active.

[0201] Optionally, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the modulation and coding scheme (MCS) of the SSB associated with the first object.

[0202] For example, when an SSB uses an MCSA to send a message, the transport resources of its associated first object are valid during Cell DTX / DRX non-active; when an SSB uses an MCS B to send a message, the transport resources of its associated first object are invalid during Cell DTX / DRX non-active.

[0203] Optionally, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the first bit or field carried by the SSB associated with the first object, or depends on the second bit or field carried by the MIB in the SSB associated with the first object.

[0204] For example, when the first bit is 1, the transmission resources of the first signal associated with it are valid during Cell DTX / DRX non-active; when the first bit is 0, the transmission resources of the first signal associated with it are invalid during Cell DTX / DRX non-active.

[0205] Optionally, the first bit can also be used to indicate the type information of the SSB.

[0206] Optionally, the validity of the transmission resources of the first object, and / or whether the transmission resources of the first object are used for transmission, depends on the PBCH payload size of the SSB associated with the first object.

[0207] For example, for an SSB with a small PBCH payload (e.g., <16 bits), the transmission resources of its associated first object are valid during Cell DTX / DRX inactivity because reception for each SSB is important at this time. Conversely, for an SSB with a large PBCH payload (e.g., >16 bits), the transmission resources of its associated first object are invalid during Cell DTX / DRX inactivity because the selection of a different first object for another SSB can be measured at this time.

[0208] This application proposes a method to determine whether the transmission resources of a first object are useful, and / or whether the transmission resources of the first object are used for transmission. This can be determined based on at least one of the following: network configuration, the second object to which the transmission of the first object is located or corresponds, the reference signal or reference signal group associated with the transmission of the first object, the characteristic combination to which the transmission of the first object belongs or is associated, the network slice to which the transmission of the first object belongs or is associated, first information related to the repeated transmission or cross-time unit transmission of the first object, second information related to the retransmission of the first object, and third information of the SSB associated with the first object. This method can improve network resource and energy efficiency and achieve network energy saving.

[0209] In some embodiments, determining the available resources for repeated transmission or transmission across time units of the first object, and / or determining whether the available resources for repeated transmission or transmission across time units of the first object are used for transmission, includes at least one of the following:

[0210] During the activation of cell DTX or cell DRX, the resources for repeated transmission of the first object are available, or the resources for cross-time unit transmission of the first object are available.

[0211] During the activation of cell DTX and cell DRX, the resources for repeated transmission of the first object are available, or the resources for cross-time unit transmission of the first object are available.

[0212] During the activation of cell DTX and / or cell DRX, resources are available for the first transmission in the repeated transmission of the first object, or resources are available for the transmission in the first time unit in the cross-time unit transmission of the first object, the first time unit comprising one or more time units.

[0213] During the inactivity of cell DTX and / or cell DRX, the resources for repeated transmission of the first object are unavailable, or the resources for cross-time unit transmission of the first object are unavailable;

[0214] During the inactivity of cell DTX and / or cell DRX, the resources of the first transmission in the repetition of the first object are available, and / or the resources of the Yth transmission in the repetition of the first object are unavailable, where Y is a positive integer greater than 1.

[0215] During the inactivity of cell DTX and / or cell DRX, the resources of the Zth transmission or the previous Z transmissions in the repeated transmission of the first object are unavailable, where Z is a positive integer greater than or equal to 1.

[0216] During the inactivity of cell DTX and / or cell DRX, resources for transmission in the second time unit of the first object's cross-time unit transmission are available, and / or resources for transmission in other time units of the first object's cross-time unit transmission besides the second time unit are unavailable, the second time unit comprising one or more time units;

[0217] During the activation period of cell DTX or cell DRX, the first object performs repeated transmission or cross-time unit transmission.

[0218] During the activation of cell DTX and cell DRX, the first object performs repeated transmission or cross-time unit transmission.

[0219] During the activation of cell DTX and / or cell DRX, the first object performs the first transmission in repeated transmission or the transmission on the first time unit in cross-time unit transmission.

[0220] During the inactive period of cell DTX and / or cell DRX, the first object does not perform repeated transmission or transmission across time units, or the repeated transmission or transmission across time units is delayed until the active period of cell DTX or cell DRX.

[0221] During the inactive period of cell DTX and / or cell DRX, the first object performs the first transmission in the repetitive transmission, and / or the first object does not perform the Yth transmission in the repetitive transmission or the Yth transmission in the repetitive transmission is delayed until the active period of cell DTX and / or cell DRX, where Y is a positive integer greater than 1.

[0222] During the inactive period of cell DTX and / or cell DRX, the first object does not perform the Zth transmission or the previous Zth transmission in the repeated transmission, or the Zth transmission or the previous Zth transmission in the repeated transmission is delayed until the active period of cell DTX and / or cell DRX, where Z is a positive integer greater than or equal to 1.

[0223] During the inactivity period of cell DTX and / or cell DRX, the first object performs a transmission on the second time unit in the cross-time unit transmission, and / or the first object does not perform a transmission on other time units in the cross-time unit transmission besides the second time unit, or the transmission on other time units in the cross-time unit transmission besides the second time unit is delayed until the activation period of cell DTX and / or cell DRX.

[0224] It should be noted that the above items can be combined in different ways depending on the first object. That is, at least two of the above items can be used to determine the available resources for repeated transmission or transmission across time units of the first object, and / or to determine whether the available resources for repeated transmission or transmission across time units of the first object are used for transmission. Wherein, the at least two items do not include mutually exclusive options.

[0225] Determining whether the available resources for repeated transmission or cross-time unit transmission of the first object are used for transmission can be understood as whether repeated transmission or cross-time unit transmission of the first object is performed, or whether the available resources for repeated transmission or cross-time unit transmission of the first object are used for actual transmission.

[0226] Determining the available resources (e.g., available slots) for the repeated transmission or scheduling across multiple time units of the first object (consisting of the aforementioned first object) can be done in one or more of the following ways:

[0227] 1) During the activation period of cell DTX or cell DRX, the resources for repeated transmission of the first object are available, or the resources for cross-time unit transmission of the first object are available.

[0228] In other words, the available resources for repeated transmissions or cross-time unit transmissions of the first object need to be in the active period of Cell DTX or Cell DRX.

[0229] 2) During the activation of cell DTX and cell DRX, the resources for repeated transmission of the first object are available, or the resources for cross-time unit transmission of the first object are available.

[0230] In other words, the available resources for repeated transmissions or cross-time unit transmissions of the first object need to be in the active period of Cell DTX and also in the active period of Cell DRX; it should be noted that the active period of Cell DTX and also in the active period of Cell DRX refers to the intersection of the active periods of Cell DTX and Cell DRX.

[0231] 3) During the activation of cell DTX and / or cell DRX, the resources for the first transmission in the repeated transmission of the first object are available, or the resources for the transmission on the first time unit in the cross-time unit transmission of the first object are available.

[0232] In other words, the resources for the first transmission (first transmission) in the repeated transmission of the first object need to be active during CellDTX / DRX;

[0233] In the first object's cross-time unit transmission (or cross-multi-time unit scheduling), the resources for transmission on one or more time units (i.e., the aforementioned first time unit) need to be in the active period of Cell DTX / DRX;

[0234] It should be noted that the active period of Cell DTX / DRX includes one of the following: the active period of Cell DTX; the active period of Cell DRX; or the active period of both Cell DTX and Cell DRX.

[0235] 4) During the inactivity of cell DTX and / or cell DRX, the resources for repeated transmission of the first object are unavailable, or the resources for cross-time unit transmission of the first object are unavailable;

[0236] In other words, the resources for repeated transmission of the first object during the non-active period of Cell DTX / DRX are unavailable;

[0237] The resources for the first object's cross-time unit transfer during the non-active period of Cell DTX / DRX are unavailable.

[0238] 5) During the inactivity of cell DTX and / or cell DRX, the resources of the first transmission in the repetition of the first object are available, and / or the resources of the Yth transmission in the repetition of the first object are unavailable, where Y is a positive integer greater than 1.

[0239] Optionally, resources are available for the first repeat transfer in a repeat transfer of the first object during the non-active period of Cell DTX / DRX.

[0240] For example, for four repeated transmissions, the first transmission can be transmitted during the non-active period, while the remaining three repeated transmissions will not be transmitted or will be delayed until the active period of the subsequent Cell DTX / DRX if they are in the non-active period.

[0241] Optionally, the resource for the Yth retransmission of the first object during the non-active period of Cell DTX / DRX is unavailable, where Y is a positive integer greater than 1.

[0242] 6) During the inactivity of cell DTX and / or cell DRX, the resources of the Zth transmission or the previous Z transmissions in the repeated transmissions of the first object are unavailable, where Z is a positive integer greater than or equal to 1.

[0243] In other words, during the non-active period of Cell DTX / DRX, the resources for the Zth transmission or the previous Z transmissions in the repeated transmissions for the first object are unavailable, where Z is a positive integer greater than or equal to 1.

[0244] Optionally, the terminal does not expect the first transmission to be repeated during the non-active period of Cell DTX / DRX.

[0245] 7) During the inactivity of cell DTX and / or cell DRX, the resources for transmission on the second time unit in the cross-time unit transmission of the first object are available, and / or the resources for transmission on other time units in the cross-time unit transmission of the first object are unavailable, the second time unit including one or more time units;

[0246] In other words, resources for transmission of a first object during a non-active period of Cell DTX / DRX are available on a specific time unit (i.e., the aforementioned second time unit) in a cross-time unit transmission.

[0247] 8) During the activation period of cell DTX or cell DRX, the first object performs repeated transmission or cross-time unit transmission.

[0248] 9) During the activation of cell DTX and cell DRX, the first object performs repeated transmission or cross-time unit transmission.

[0249] 10) During the activation of cell DTX and / or cell DRX, the first object performs the first transmission in repeated transmission or the transmission on the first time unit in cross-time unit transmission.

[0250] 11) During the inactive period of cell DTX and / or cell DRX, the first object does not perform repeated transmission or transmission across time units, or the repeated transmission or transmission across time units is delayed until the active period of cell DTX or cell DRX.

[0251] Repeated transmissions or transmissions across time units during the non-active period of a Cell DTX / DRX: transmissions are either not transmitted or delayed until the active period of a subsequent Cell DTX / DRX.

[0252] 12) During the inactive period of cell DTX and / or cell DRX, the first object performs the first transmission in the repetitive transmission, and / or the first object does not perform the Yth transmission in the repetitive transmission or the Yth transmission in the repetitive transmission is delayed until the active period of cell DTX and / or cell DRX, where Y is a positive integer greater than 1.

[0253] The Yth transmission in a repeated transmission during the non-active period of a Cell DTX / DRX: either not transmitted or delayed until the active period of a subsequent Cell DTX / DRX.

[0254] 13) During the inactive period of cell DTX and / or cell DRX, the first object does not perform the Zth transmission or the previous Zth transmission in the repeated transmission, or the Zth transmission or the previous Zth transmission in the repeated transmission is delayed until the active period of cell DTX and / or cell DRX, where Z is a positive integer greater than or equal to 1.

[0255] The first Z or Zth transmission in a repeated transmission during the non-active period of a Cell DTX / DRX: not transmitted or delayed until the active period of a subsequent Cell DTX / DRX.

[0256] For example, for four repeated transmissions, the first transmission can be performed during the non-active period, while the remaining three repeated transmissions will either not be performed or will be delayed until the active period of the subsequent Cell DTX / DRX if they are in the non-active period.

[0257] 14) During the inactive period of cell DTX and / or cell DRX, perform the transmission on the second time unit in the cross-time unit transmission of the first object, and / or, do not perform the transmission on other time units in the cross-time unit transmission of the first object except for the second time unit, or delay the transmission on other time units in the cross-time unit transmission except for the second time unit until the active period of cell DTX and / or cell DRX.

[0258] Transmissions in other time units besides the aforementioned second time unit during the non-active period of Cell DTX / DRX: not transmitted or delayed until the active period of subsequent Cell DTX / DRX.

[0259] This application provides a method for determining the available resources for repeated transmission or cross-time unit transmission of a first object. The method for determining whether the available resources for repeated transmission or cross-time unit transmission of a first object are used for transmission can improve network resource and energy efficiency and achieve network energy saving.

[0260] In some embodiments, during the inactivity period of cell DTX and / or cell DRX, it is determined that the first object performs retransmission or cross-time unit transmission based on at least one of the following: or, it is determined that the first object does not perform retransmission or cross-time unit transmission; or, it is determined that the first object is delayed until the activation period of cell DTX and / or cell DRX to perform retransmission or cross-time unit transmission.

[0261] Network configuration;

[0262] The fourth object in which the repeated transmission or cross-time unit transmission of the first object is located or corresponds, the fourth object including at least one of cell, frequency band, carrier, transmit / receive point (TRP), sub-band and frequency range;

[0263] The reference signal or reference signal group associated with the repeated transmission or cross-time unit transmission of the first object;

[0264] The combination of characteristics to which the repeated transmission or cross-time unit transmission of the first object belongs or is associated;

[0265] The repeated transmission or cross-time unit transmission of the first object belongs to or is associated with the network slice;

[0266] Terminal capabilities are used to indicate whether the terminal supports repeated transmission or cross-time unit transmission of the first object under the configuration of cell DTX and / or cell DRX.

[0267] In one implementation, during the inactive period of cell DTX and / or cell DRX, the first object may perform repeated transmission or cross-time unit transmission, or may not perform repeated transmission or cross-time unit transmission, or may delay repeated transmission or cross-time unit transmission until the active period of cell DTX and / or cell DRX, depending on the network configuration.

[0268] For example, whether the first signal retransmission can be transmitted during the non-active period of Cell DRX can be configured by the network.

[0269] In one implementation, during the inactive period of cell DTX and / or cell DRX, the first object performs repeated transmission or cross-time unit transmission, or does not perform repeated transmission or cross-time unit transmission, or delays until the active period of cell DTX and / or cell DRX to perform repeated transmission or cross-time unit transmission, depending on the fourth object in which the repeated transmission or cross-time unit transmission of the first object is located or corresponds, the fourth object including at least one of cell, frequency band, carrier, transmit / receive point TRP, subband and frequency range.

[0270] For example, during the inactivity period of Cell DRX in the first cell, the retransmission of the first object is invalid, while the retransmission of the first object is valid for other cells.

[0271] In one implementation, during the inactive period of cell DTX and / or cell DRX, the first object performs repeated transmission or cross-time unit transmission, or does not perform repeated transmission or cross-time unit transmission, or delays to the active period of cell DTX and / or cell DRX to perform repeated transmission or cross-time unit transmission, depending on the reference signal or reference signal group associated with the repeated transmission or cross-time unit transmission of the first object.

[0272] For example, for a first object associated with a specific SSB or group of SSBs, the retransmission resources for that first object are available during the inactivity of Cell DRX. However, for a first object associated with a different group of SSBs, the transmission resources for that first object are unavailable during the inactivity of Cell DRX.

[0273] In one implementation, during the inactive period of cell DTX and / or cell DRX, the first object performs repeated transmission or cross-time unit transmission, or does not perform repeated transmission or cross-time unit transmission, or delays to the active period of cell DTX and / or cell DRX for repeated transmission or cross-time unit transmission, depending on the characteristic combination to which or associated repeated transmission or cross-time unit transmission of the first object belongs.

[0274] For example, for repeated CG PUSCH transmissions used for small data transfers, transmission resources are available during cell DRX inactivity periods for CG PUSCH transmissions corresponding to a specific feature combination (e.g., associated with a specific PRACH transmission). However, for repeated CG PUSCH transmissions corresponding to a different feature combination, transmission resources are unavailable during cell DRX inactivity periods.

[0275] In one implementation, during the inactive period of cell DTX and / or cell DRX, the first object may be retransmitted or transmitted across time units, or may not be retransmitted or transmitted across time units, or may be retransmitted or transmitted across time units during the active period of cell DTX and / or cell DRX, depending on the network slice to which or which the retransmission or transmission across time units of the first object belongs.

[0276] For example, for repeated CG PUSCH transmissions, transmission resources are available during the cell's DRX inactivity period if the CG PUSCH transmission corresponds to a specific network slice (e.g., associated with a specific PRACH resource). However, for repeated CG PUSCH transmissions corresponding to a different network slice, transmission resources are unavailable during the cell's DRX inactivity period.

[0277] In one implementation, during the inactive period of cell DTX and / or cell DRX, the first object performs repeated transmission or cross-time unit transmission, or does not perform repeated transmission or cross-time unit transmission, or delays to the active period of cell DTX and / or cell DRX for repeated transmission or cross-time unit transmission, depending on the terminal capability.

[0278] Optionally, the terminal capability is used to indicate whether the terminal supports repeated transmission or cross-time unit transmission of the first object under the configuration of cell DTX and / or cell DRX.

[0279] For example, a terminal can indirectly indicate whether it supports the transmission of the first object under Cell DTX / DRX by selecting a specific PRACH transport.

[0280] For example, a terminal can indirectly indicate whether it supports the transmission of the first object under CellDTX / DRX by selecting a specific PRACH or WUS transport.

[0281] For example, the terminal's ability to perform the first signal transmission under Cell DTX / DRX is reported to the network via dedicated signaling before entering RRC release.

[0282] The communication method provided in this application provides multiple methods for determining the available resources for repeated transmission or cross-time unit transmission of a first object during different cell DTX and / or cell DRX periods, as well as multiple methods for determining whether the available resources for repeated transmission or cross-time unit transmission of the first object are used for transmission. This can improve the utilization rate of transmission resources and achieve energy saving.

[0283] In some embodiments, determining the validity of the transmission resources of the second object, and / or whether the transmission resources of the second object are used for transmission, includes at least one of the following:

[0284] The validity of the transmission resources of the second object, and / or whether the transmission resources of the second object are used for transmission, are unrelated to the first SSB;

[0285] The validity of the transmission resources of the second object, and / or whether the transmission resources of the second object are used for transmission, are related to the first SSB;

[0286] The validity of the transmission resources of the second object, and / or whether the transmission resources of the second object are used for transmission, is determined based on at least one of the following: the most recent SSB associated with the second object; whether there is an SSB within a preset window; the number or proportion of SSBs that are inactive during cell DTX and / or cell DRX.

[0287] The first SSB includes at least one of the following: an SSB that is invalid under the configuration of cell DTX and / or cell DRX; an SSB that is not transmitted under the configuration of cell DTX and / or cell DRX; or an SSB that is in the inactive period of cell DTX and / or cell DRX.

[0288] As previously mentioned, the second object includes the configured authorized physical uplink shared channel CG PUSCH and / or wake-up signal WUS.

[0289] It is understandable that the validity of the transmission resources of the second object, or whether they are used for transmission, should be considered in light of one or more of the following factors:

[0290] 1) The validity of the transmission resources of the second object does not take into account invalid SSBs or SSBs that are not actually transmitted or SSBs that are in the non-active period of Cell DTX / DRX under the configuration of Cell DTX and / or Cell DRX.

[0291] For example, under the configuration of Cell DTX and / or Cell DRX, if an SSB is in the non-active period of Cell DTX / DRX, and the CGPUSCH resource is before the SSB or too close to the last symbol of the SSB (e.g., the time domain interval is less than a certain value), then CGPUSCH is considered valid.

[0292] 2) The validity of the transmission resources of the second object is considered under the configuration of Cell DTX and / or Cell DRX, including invalid SSBs, SSBs that are not actually transmitted, or SSBs that are in the non-active period of Cell DTX / DRX.

[0293] For example, the SSBs considered in the CGPUSCH resource validity determination include all SSBs that are active or non-active during Cell DTX / DRX periods.

[0294] 3) Whether the transmission resources of the second object are used for actual transmission without considering the configuration of Cell DTX and / or Cell DRX, whether they are invalid SSBs or SSBs that are not actually transmitted, or SSBs that are in the non-active period of Cell DTX / DRX.

[0295] For example, under the configuration of Cell DTX and / or Cell DRX, if a CGPUSCH resource is in the Cell DTX / DRX non-active period and it is before the SSB or too close to the last symbol of the SSB (e.g., less than a certain time interval), CGPUSCH will still be actually sent on that CGPUSCH resource.

[0296] 4) Whether the transmission resources of the second object are used for actual transmission, consider the configuration of Cell DTX and / or Cell DRX, invalid SSBs or SSBs that are not actually transmitted or SSBs that are in the Cell DTX / DRX non-active period.

[0297] For example, whether a PUSCH is sent on a CG PUSCH resource, the SSBs considered include all SSBs that are active during Cell DTX and / or DRX activation and inactive.

[0298] 5) The validity of the transmission resources of the second object, or whether they are used for transmission, depends on whether or how many of its associated nearest SSBs or SSBs within a certain window are in the Cell DTX / DRX non-active period.

[0299] This application proposes a method for determining the validity of transmission resources of a second object or whether it is used for transmission in a Cell DTX / DRX scenario, which can improve network resource and energy efficiency and achieve network energy saving.

[0300] In some embodiments, determining the validity of the transmission resources of the second object, and / or determining whether the transmission resources of the second object are used for transmission, further includes: determining the association between the transmission resources of the second object and the SSB;

[0301] Determining the association between the transmission resources of the second object and the SSB includes one of the following:

[0302] Based on the configuration of the cell DTX and / or the cell DRX, determine the valid transmission resources of the second object and / or the transmission resources of the SSB. Based on the valid transmission resources of the second object and / or the transmission resources of the SSB, associate the transmission resources of the second object with the SSB according to the first mapping rule.

[0303] Associating the transmission resources and SSB of the second object according to the first mapping rule, determining whether the transmission resources of the second object are used for transmission based on the configuration of the cell DTX and / or the configuration of the cell DRX, and / or determining whether the SSB associated with the transmission resources of the second object is transmitted.

[0304] It is understandable that the association of resources supporting the transfer from SSB to a second object (such as CGPUSCH or WUS) includes one or more of the following methods:

[0305] First consider the configuration of Cell DTX / DRX, then consider the association of SSB to the second object's transmission resources.

[0306] For example, the configuration of cell DTX and DRX can be considered first to determine the effective SSB resources and / or CGPUSCH resources. Then, based on the effective resources, the two types of channel resources are mapped according to a specific mapping order (the aforementioned first mapping rule).

[0307] First consider the association between SSB and CGPUSCH resources, then consider the configuration of Cell DTX / DRX.

[0308] For example, the mapping of two channel resources can be performed according to specific mapping rules or order, regardless of the configuration during the active / non-active periods of CellDTX and DRX. Then, the transmission of the actual SSB and / or CG PUSCH resources depends on the configuration of cell DTX / DRX.

[0309] As a sub-implementation of the previous embodiment, determining whether the transmission resources of the second object are used for transmission, and / or determining whether the SSB associated with the transmission resources of the second object is transmitted, based on the configuration of the cell DTX and / or the configuration of the cell DRX, includes at least one of the following:

[0310] If it is determined that an SSB will not be transmitted based on the configuration of the cell DTX and / or the configuration of the cell DRX, the transmission resources of the second object corresponding to the SSB will not be used for transmission.

[0311] If it is determined, based on the configuration of the cell DTX and / or the configuration of the cell DRX, that the transmission resources of the second object are not used for transmission, the SSB corresponding to the transmission resources of the second object is transmitted separately.

[0312] If the configuration of the cell DTX and / or the configuration of the cell DRX determines that the transmission of the SSB is permitted, the transmission of the second object corresponding to the SSB is permitted.

[0313] If it is determined that the transmission of a second object is permitted based on the configuration of the cell DTX and / or the configuration of the cell DRX, the transmission of the SSB corresponding to the second object is permitted.

[0314] It is understandable that, for the association of SSB to second object transfer resources without considering Cell DTX / DRX, SSB and second object transfer also include one or more of the following methods:

[0315] If the SSB fails to transmit due to Cell DTX / DRX configuration, the corresponding second object will not be transmitted.

[0316] If the SSB is not transmitted due to Cell DTX / DRX configuration, the corresponding second object can be transmitted separately; if the second object is not transmitted due to Cell DTX / DRX configuration, the corresponding SSB will not be transmitted.

[0317] When SSB is allowed to transmit under Cell DTX / DRX configuration, the corresponding second object is also allowed to transmit.

[0318] For example, even if CGPUSCH is in the Cell DRX non-active period, CG PUSCH is allowed to transmit as long as SSB is in the Cell DTX active period.

[0319] If the second object is allowed to be transmitted under the Cell DTX / DRX configuration, then the corresponding SSB is also allowed to be transmitted.

[0320] This application proposes a method for associating the transmission resources of a second object with the SSB in a Cell DTX / DRX scenario, which can improve network resource and energy efficiency and achieve network energy saving.

[0321] In some embodiments, when the communication device is a terminal, the terminal does not expect the transmission resources of the SSB and the transmission resources of the second object associated with the SSB to be in different cell DTX and / or cell DRX periods, the cell DTX and / or cell DRX periods including the active period or inactive period of cell DTX and / or cell DRX.

[0322] For example, if a terminal does not expect the Cell DTX / DRX configured by the network to cause SSB resources to appear in the active period, its associated CGPUSCH or WUS resources will appear in the non-active period.

[0323] In some embodiments, when the communication device is a terminal, the terminal does not expect that: the transmission resources of the SSB are inactive during cell DTX and / or cell DRX, while a portion of the transmission resources of the second object associated with the SSB are active during cell DTX and / or cell DRX.

[0324] For example, although the terminal may allow the Cell DTX configuration to cause the SSB resource to be in the active period while its associated CG PUSCH or WUS resource is in the inactive period, the terminal does not expect the Cell DTX configuration to cause the SSB to be in the non-active period while its associated CG PUSCH or WUS resource is in the active period.

[0325] In some embodiments, the time period or time window corresponding to the association between the transmission resources of the second object and the SSB is related to the period of cell DTX and / or cell DRX.

[0326] For example, the size of the DTX / DRX cycle is an integer multiple of the association mode cycle of the SSB to CG PUSCH or WUS resources.

[0327] In some embodiments, the time period or time window corresponding to the resources repeatedly transmitted by the second object is related to the period of cell DTX and / or cell DRX.

[0328] For example, the size of the DTX / DRX period is an integer multiple of the time period corresponding to the repeated transmission resources of CG PUSCH or WUS.

[0329] In the embodiments of this application, various scenarios of the association between the transmission resources of the second object and the SSB in the Cell DTX / DRX scenario are proposed, which can improve network resource and energy efficiency and achieve network energy saving.

[0330] For uplink transmissions in small data transmission, or uplink transmissions in LTM, RACH less, or WUS processes, it is necessary to consider the validity of the TA (Transmission Target) data. This requires considering whether the transmission of relevant measurement signals is affected by Cell DTX / DRX to ensure the accuracy of TA acquisition. The following is an example.

[0331] In some embodiments, determining the validity of the timing advance TA includes one of the following:

[0332] The validity of the TA is independent of the second SSB;

[0333] The validity of the TA is related to the second SSB;

[0334] The second SSB includes at least one of the following: an SSB that is invalid under the configuration of cell DTX and / or cell DRX; an SSB that is not transmitted under the configuration of cell DTX and / or cell DRX; or an SSB that is in the inactive period of cell DTX and / or cell DRX.

[0335] Determining the validity of timing advance TA refers to determining the validity of TA in uplink signal transmission. One or more of the following methods can be considered:

[0336] 1) TA validity does not consider invalid SSBs, SSBs that are not actually sent, or SSBs that are in the Cell DTX / DRX non-active period under the Cell DTX / DRX configuration.

[0337] For example, the validity of a TA is determined based on whether the change in RSRP between two SSB measurements exceeds a first threshold. If it does, the TA is considered invalid. The SSB selected by the terminal needs to ensure that both RSRP measurements are taken during the Cell DTX / DRX active time.

[0338] 2) TA validity considers invalid SSBs, SSBs that are not actually being sent, or SSBs that are in the Cell DTX / DRX non-active period under the Cell DTX / DRX configuration.

[0339] In cases where the validity of the TA relates to the second SSB, the determination of the validity of the timing advance of the TA includes at least one of the following:

[0340] a) If the change in RSRP between two SSB measurements exceeds the first threshold, the timing advance TA is invalid;

[0341] For example, the validity of a TA is determined based on whether the change in RSRP between two SSB measurements exceeds a first threshold; if it does, the TA is considered invalid.

[0342] b) If the change in RSRP between two SSB measurements exceeds the first threshold, and the second SSB measurement occurs during the cell DRX inactive period, the timed advance TA is invalid.

[0343] For example, the validity of a TA is determined based on whether the change in RSRP between two SSB measurements exceeds a first threshold. If it does, it is further determined whether the second measured SSB is in the non-active period of Cell DTX. If the second measured SSB is in the non-active period of Cell DTX, the terminal considers the TA invalid.

[0344] c) If the change in RSRP between two SSB measurements exceeds the first threshold, and the SSB of the first or second measurement is in the inactive period of the cell DRX, the timed advance TA is invalid.

[0345] For example, the validity of a TA is determined based on the transformation of the RSRP between two SSB measurements. If either of the two measurements occurs during the non-active period of a Cell DTX, the terminal considers the TA invalid.

[0346] d) If the change in RSRP between two SSB measurements exceeds the first threshold, and the second SSB measurement is taken during the inactive period of cell DRX, determine whether the TA is invalid based on whether the TA timer has expired;

[0347] For example, the validity of a TA is determined based on whether the change in RSRP between two SSB measurements exceeds a first threshold. If it does, the TA is considered invalid. For the second SSB measurement, if it is in the non-active period of Cell DTX, the terminal further determines whether the TA is invalid based on whether the timing advance timer (TAtimer) has timed out.

[0348] e) If the change in RSRP between two SSB measurements exceeds the first threshold, and the SSB of the first or second measurement is in the inactive period of the cell DRX, determine whether the TA is invalid based on whether the TA timer has expired.

[0349] For example, the validity of a TA is determined based on the change in RSRP between two SSB measurements. For either SSB measurement, if it falls within the non-active period of a Cell DTX, the terminal further determines whether the TA is invalid based on whether the timing advance timer (TAtimer) has timed out.

[0350] The aforementioned first threshold can be network-configured, protocol-predefined, or predetermined.

[0351] In this application embodiment, a method for determining the effectiveness of timing advance TA in Cell DTX / DRX scenarios is proposed. By considering whether the transmission of relevant measurement signals is affected by Cell DTX / DRX, the accuracy of TA acquisition can be improved.

[0352] When multiple data transmission types are supported, such as RACH-based data transmission in RRC idle / inactive states (e.g., in Msg3 PUSCH or msgAPUSCH), CGPUSCH-based data transmission, or paging-based data transmission, it is necessary to consider which data transmission type to choose and / or whether to transmit data at all. This may require measuring the corresponding signals, and such measurements need to consider the impact of Cell DTX / DRX. Therefore, the following embodiments are provided.

[0353] In some embodiments, determining the type of the first data transmission, or determining whether to perform the first data transmission, or determining both the type of the first data transmission and whether to perform the first data transmission of that type, includes at least one of the following:

[0354] The type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission of that type is performed, are unrelated to the third SSB;

[0355] The type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission of that type is performed, are related to the third SSB;

[0356] The type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission of the type is performed, are related to whether one or more transmission resources corresponding to the first data transmission are in the active period of cell DTX and / or cell DRX.

[0357] The third SSB includes at least one of the following: an SSB that is invalid under the configuration of cell DTX and / or cell DRX; an SSB that is not transmitted under the configuration of cell DTX and / or cell DRX; or an SSB that is in the inactive period of cell DTX and / or cell DRX.

[0358] In one implementation, the type of the first data transmission is determined, or it is determined whether to perform the first data transmission, or the type of the first data transmission is determined and it is determined whether to perform the first data transmission of the type, without considering invalid SSBs or SSBs that are not actually transmitted under the CellDTX / DRX configuration, or SSBs that are in the Cell DTX / DRX non-active period.

[0359] Optionally, when the type of the first data transmission, or whether to perform the first data transmission, or the type of the first data transmission and whether to perform the first data transmission of that type, are unrelated to the third SSB, determining the type of the first data transmission, or determining whether to perform the first data transmission, or determining the type of the first data transmission and whether to perform the first data transmission of that type, includes:

[0360] Based on the measurement results of the fourth SSB, determine the type of the first data transmission, or determine whether to perform the first data transmission, or determine both the type of the first data transmission and whether to perform the first data transmission of the aforementioned type.

[0361] The fourth SSB includes at least one of the following: an SSB that is active under the configuration of cell DTX and / or cell DRX; an SSB transmitted under the configuration of cell DTX and / or cell DRX; or an SSB that is active during the activation period of cell DTX and / or cell DRX.

[0362] For example, the type of the first data transmission is determined based on the range of a certain metric (e.g., RSRP) measured by the SSB. If the first type is selected in the first range, the second type is selected in the second range. Terminal measurements only consider SSBs that are active during Cell DTX / DRX, or SSBs that are valid under the cell DTX configuration and / or cell DRX configuration, or SSBs transmitted under the cell DTX configuration and / or cell DRX configuration. That is, terminal measurements only consider the fourth SSB.

[0363] For example, the type of the first data transmission is determined based on the range of a certain metric (e.g., RSRP) measured by the SSB. If the first type is selected in the first range, the second type is selected in the second range. Terminal measurements only consider SSBs that are active during Cell DTX / DRX, or SSBs that are valid under the cell DTX configuration and / or cell DRX configuration, or SSBs transmitted under the cell DTX configuration and / or cell DRX configuration. Furthermore, the second operation is performed when the time interval between the most recent fourth SSB and the first reference time point before the first data transmission is executed exceeds or is not less than a second threshold.

[0364] The second operation includes at least one of the following:

[0365] Discard the first data transmission;

[0366] The type of the first data transmission is determined to be the default data transmission type, for example, RACH-based data transmission;

[0367] Trigger the transmission of the first reference signal. Optionally, the first reference signal can be one of the following: SSB, two-level SSB, the first-level SSB in two-level SSB, or the second-level SSB in two-level SSB.

[0368] Based on a non-SSB measurement method, determine the type of the first data transmission, or determine whether to discard or not discard at least one type of first data transmission, or determine whether to enter the RRC connection process;

[0369] Non-SSB measurement methods include: based on whether the TA is valid or the size of the TA, or based on changes in its own position.

[0370] The first reference time point includes: the start time of the first data transmission.

[0371] In the embodiments of this application, determining the type of the first data transmission, or whether to perform the first data transmission, or the type of the first data transmission and whether to perform the first data transmission of the type, without considering invalid SSBs or SSBs that are not actually transmitted under the Cell DTX / DRX configuration, or SSBs that are in the Cell DTX / DRX non-active cycle, can improve the accuracy of determining the data transmission type and reduce data transmission latency.

[0372] In one implementation, the type of the first data transmission is determined, or it is determined whether to perform the first data transmission, or the type of the first data transmission and whether to perform the first data transmission of the type are determined, taking into account invalid SSBs or SSBs that are not actually transmitted under the Cell DTX / DRX configuration, or SSBs that are in the Cell DTX / DRX non-active period.

[0373] Optionally, when the type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission of that type is performed, are related to a third SSB, determining the type of the first data transmission, or determining whether the first data transmission is performed, or determining the type of the first data transmission and whether the first data transmission of that type is performed, includes at least one of the following:

[0374] Based on the measurement results of the fifth SSB, determine the type of the first data transmission, or determine whether to perform the first data transmission, or determine both the type of the first data transmission and whether to perform the first data transmission of the aforementioned type.

[0375] If the time interval between the nearest fourth SSB and the first reference time point before the first data transmission is executed exceeds or is not less than the second threshold, the type of the first data transmission is determined based on the measurement result of the fifth SSB, or whether to execute the first data transmission, or the type of the first data transmission and whether to execute the first data transmission of the specified type are determined.

[0376] Based on the measurement results of the fifth SSB and the method of non-SSB measurement, determine the type of the first data transmission, or determine whether to perform the first data transmission, or determine the type of the first data transmission and determine whether to perform the first data transmission of the type.

[0377] If the time interval between the nearest fourth SSB and the first reference time point before the first data transmission is executed exceeds or is not less than the second threshold, the type of the first data transmission is determined based on the measurement result of the fifth SSB and the method of non-SSB measurement, or whether to execute the first data transmission, or the type of the first data transmission and whether to execute the first data transmission of the type are determined.

[0378] The fifth SSB includes the third SSB;

[0379] The fourth SSB includes at least one of the following: an SSB that is active under the configuration of cell DTX and / or cell DRX; an SSB transmitted under the configuration of cell DTX and / or cell DRX; or an SSB that is active during the activation period of cell DTX and / or cell DRX.

[0380] For example, the type of the first data transmission is determined based on the range of a certain metric (e.g., RSRP) of the SSB measurement. If the first type is selected in the first range, the second type is selected in the second range. The terminal also considers SSB measurements in the non-active cycle of CellDTX.

[0381] For example, the determination of the type of the first data transmission is based on the range of a certain metric (e.g., RSRP) measured by the SSB. If the first type is selected within the first range, the second type is selected within the second range. If the time interval between the most recent fourth SSB (i.e., an SSB valid under the Cell DTX / DRX configuration, an SSB that is actually transmitted, or an SSB in the Cell DTX / DRX active cycle) and the first reference time point (e.g., the data transmission start time) exceeds or is not less than the second threshold, it is considered that the SSB in the Cell DTX / DRX non-active cycle can also be measured.

[0382] For example, the type of the first data transmission is determined based on the range of a certain metric (e.g., RSRP) of the SSB measurement. If the first type is selected in the first range, the second type is selected in the second range. The terminal also considers SSB measurements in the non-active cycle of Cell DTX, and also considers other non-SSB measurement methods (e.g., based on whether the TA is valid or the TA size, or the terminal location) to determine the type of the first data transmission.

[0383] For example, the type of the first data transmission is determined based on the range of a certain metric (e.g., RSRP) measured by the SSB. If the first type is selected within the first range, the second type is selected within the second range. When the time interval between the nearest fourth SSB (i.e., an SSB valid under the Cell DTX / DRX configuration, an actually transmitted SSB, or an SSB in a Cell DTX / DRX active cycle) and the first reference time point (e.g., the data transmission start time) before the first data transmission is executed exceeds or is not less than the second threshold, then SSBs in the Cell DTX / DRX non-active cycle are also considered for measurement. Furthermore, other non-SSB measurement methods (e.g., based on TA validity or TA size, or terminal location) are also considered to determine the type of the first data transmission.

[0384] It should be noted that the aforementioned second threshold may be configured by the network, predefined by the protocol, or predetermined.

[0385] In the embodiments of this application, determining the type of the first data transmission, or whether to perform the first data transmission, or the type of the first data transmission and whether to perform the first data transmission of the type, by considering invalid SSBs or SSBs that are not actually transmitted under the Cell DTX / DRX configuration, or SSBs that are in the Cell DTX / DRX non-active cycle, can improve the accuracy of determining the data transmission type and reduce data transmission latency.

[0386] In one implementation, the type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission of the type is performed, depends on whether one or more transmission resources corresponding to the first data transmission are in the active period of cell DTX and / or cell DRX, as shown in the following embodiments.

[0387] Optionally, when the type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission is performed, are related to whether one or more transmission resources corresponding to the first data transmission are active during cell DTX and / or cell DRX, determining the type of the first data transmission includes at least one of the following:

[0388] If the type of the first data transmission has been determined to be the first type, and the time interval between the first resource of the first data transmission of the first type and the second reference time point exceeds or is not less than the third threshold, then the type of the first data transmission is determined to be the second type.

[0389] The type of the first data transmission is determined based on the time interval between the first resource of the first data transmission of the first type and the second reference time point, and the time interval between the second resource of the first data transmission of the second type and the second reference time point.

[0390] Wherein, the first resource is a transmission resource that is in the active period of cell DTX and / or cell DRX among one or more transmission resources corresponding to the first data transmission of the first type;

[0391] The second resource is a transmission resource that is active during cell DTX and / or cell DRX among one or more transmission resources corresponding to the first data transmission of the second type;

[0392] The second type is different from the first type;

[0393] The first reference time point includes the data arrival time.

[0394] For example, when the network supports two data transmission types (Type 1 and Type 2), the terminal determines the type of the first data transmission as Type 1 according to specific rules. If the resource in Type 1 that is in Cell DTX / DRX active time is more than a certain time interval (the aforementioned third threshold) away from the second reference time point (e.g., data arrival time), the terminal selects Type 2.

[0395] For example, when the network supports two data transmission types (Type 1 and Type 2), the terminal determines the type of the first data transmission as Type 1 according to specific rules. If the resource in Type 1 where the Cell DTX / DRX active time is more than a certain time interval (the aforementioned third threshold) away from the second reference time point (e.g., data arrival time), the terminal attempts to select Type 2. Optionally, Type 2 can be determined using similar rules to determine whether it can be selected.

[0396] Optionally, the third threshold may be configured by the network, agreed upon by the protocol, or predetermined. Optionally, the third threshold may be the same as or different from the second threshold.

[0397] For example, when the network supports two data transmission types (Type 1 and Type 2), the terminal needs to determine which data transmission type to select based on at least the nearest resource of Type 1 that is active during Cell DTX / DRX time and / or the nearest resource of Type 2 that is active during Cell DTX / DRX time. For example, the data type whose nearest resource is closer to a second reference time point (e.g., data arrival time) can be selected.

[0398] In the embodiments of this application, the type of the first data transmission, or whether the first data transmission is performed, or the type of the first data transmission and whether the first data transmission is performed, depends on whether one or more transmission resources corresponding to the first data transmission are in the active period of cell DTX and / or cell DRX. This can improve the accuracy of determining the data transmission type or whether to perform data transmission and reduce data transmission latency.

[0409] Downlink data transmission is carried via RAR;

[0410] Optional, data transfer based on CG PUSCH includes: small data transfer via CGPUSCH in RRC idle / inactive state.

[0411] Paging-triggered data transmission refers to data transmission triggered by paging.

[0412] Data transmission carried by paging, for example, data transmission carried by paging itself.

[0413] Optionally, the first data transmission type can be one of the following: data transmission based on the random access channel (RACH); data transmission based on the CGPUSCH; data transmission triggered by paging; data transmission carried by paging; data transmission scheduled by the paging PDCCH; or data transmission scheduled by a dedicated PDCCH.

[0414] In this embodiment, multiple data transmission types are supported. The selection of data transmission type and / or whether to transmit data takes into account the impact of Cell DTX / DRX, which can reduce data transmission latency.
