[0085] As shown in FIG. 2, the resource management method includes:

[0086] In step S201, the terminal determines a second time-domain resource in which the first measurement and the uplink transmission collide.

[0087] In some embodiments, the terminal can determine, in a first time domain resource for transmitting a reference signal (RS) for a first measurement, a second time domain resource that conflicts with uplink (UL) transmission.

[0088] In some embodiments, the terminal can be a terminal that does not support full-duplex communication.

[0089] In some embodiments, the terminal can be a terminal for half-duplex (HD) communication.

[0090] In some embodiments, the terminal can be a terminal for half-duplex frequency division duplex (FDD) communication, HD-FDD UE.

[0091] In some embodiments, the terminal is a terminal that does not support full-duplex communication in a non-terrestrial network (NTN).

[0092] In some embodiments, the terminal can be a terminal for half-duplex frequency division duplex communication in a non-terrestrial network, HD-FDD UE.

[0093] In some embodiments, the HD-FDD terminal can determine, after determining a first time domain resource for transmitting a reference signal related to a first measurement, whether there is a second time domain resource in the first time domain resource that conflicts with uplink transmission of the HD-FDD terminal.

[0094] In some embodiments, the HD-FDD terminal can determine, when it is determined that uplink transmission is needed, whether the uplink transmission conflicts with a first time domain resource for transmitting a reference signal related to a first measurement; if so, determine a second time domain resource that conflicts from the first time domain resource.

[0095] In some embodiments, the time domain resource units included in the first time domain resource can be set according to actual needs, for example, frame (Frame), subframe (SubFrame), slot, symbol (Symbol), millisecond (ms), etc. For the sake of simplicity, in the following embodiments, a symbol is taken as a time domain resource unit for illustration, and the symbol for transmitting a reference signal can also be referred to as a reference signal symbol (RS Symbol).

[0096] In some embodiments, the first measurement based on the downlink reference signal can also be referred to as downlink measurement (DL measurement).

[0097] In some embodiments, the first measurement can comprise a Layer 3 measurement (L3 measurement) and / or a measurement for handover.

[0098] Wherein, the handover can comprise a satellite handover and / or a handover in a conditional handover (CHO) manner.

[0099] Wherein, the satellite handover can also comprise a satellite to satellite handover or also called a satellite switch, which can comprise a satellite switching with re-synchronization.

[0100] It should be noted that the handover in the NTN scenario can comprise a terrestrial to satellite handover, a terrestrial to satellite handover, a satellite to aircraft handover, an aircraft to aircraft handover, etc.

[0101] In some embodiments, the downlink reference signal that can be used to perform the first measurement described above can comprise a synchronization signal block / physical broadcast channel signal block (SSB), which can specifically comprise a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), etc.

[0103] In step S202, the first measurement is prioritized to be ensured on the second time domain resource.

[0104] In some embodiments, the terminal can determine, in the first time domain resource used for transmission of the downlink reference signal related to the first measurement, whether there is a second time domain resource that conflicts with the uplink transmission, and then can require the first measurement to be prioritized on the second time domain resource, i.e., the transmission of the downlink reference signal related to the first measurement is prioritized on the second time domain resource.

[0105] In some embodiments, the terminal can determine, in the RS symbol used for transmission of the downlink reference signal related to the first measurement, whether there is a RS symbol that conflicts with the uplink transmission, and then can require the transmission of the downlink reference signal related to the first measurement to be prioritized on the conflicting RS symbol.

[0106] In some embodiments, the basic principle is to ensure the measurement opportunities based on the downlink reference signal, for example, for an HD-FDD terminal, the radio resource management (RRM) based downlink measurement is prioritized over the uplink transmission. The basic principle is to guarantee the measurement opportunities which are based on DL RS, i.e. the RRM DL measurement is prioritized over the UL transmission of HD-FDD UE.

[0107] In some embodiments, the terminal can ensure the first measurement on the second time-domain resource based on a predefined resource management method. The predefined resource management method can be set by at least one of the following two options: a first option A1, which can define modulation restriction and / or availability of the resource, for example, define that the terminal is not expected to perform uplink transmission on the first time-domain resource used for transmitting the reference signal of the downlink; and a second option A2, which can explicitly indicate the first condition required to be met for performing the first measurement, which is equivalent to indicating the first condition required to be met for allowing uplink transmission, for example, the first measurement needs to be performed under the condition that the first condition is met, which is equivalent to allowing uplink transmission on the second time-domain resource after the first condition is met, that is, uplink transmission on the second time-domain resource can be allowed under the condition that it is determined that the uplink transmission on the second time-domain resource will not have a substantial impact on the execution of the first measurement; wherein the first condition is used to indicate that the number of available reference signals in the time period related to the first measurement reaches a number threshold.

[0108] wherein the available reference signal can refer to a reference signal expected to be received, that is, a reference signal that can be received on a transmission occasion or time-domain resource without conflict, which can also be equivalent to the number of transmission occasions or time-domain resources without conflict.

[0109] In an implementation, the first option A1 defines scheduling restriction / availability, for example, the terminal should not transmit PUCCH / PUSCH / SRS on the RS symbol to be measured. This option is more in line with the traditional logic. Define scheduling restriction / availability, i.e. UE is not expected to transmit PUCCH / PUSCH / SRS on RS symbols to be measured, This option is more aligned with the legacy logic.

[0110] In some embodiments, the second option A2 explicitly indicates that the above request only applies to the case when the required number of SSB available at the UE during the specific measurement period. This option is more flexible for UE implementation.

[0111] In some embodiments, different resource management methods can be employed for different first measurements, i.e., different first options A1 and / or different second options A2 are set.

[0112] In some embodiments, for different first measurements, the first option A1 can include at least one of the following: no uplink transmission is expected on the first time-domain resource within a first time window, the first time window being a time window for measuring a reference signal; no uplink transmission is expected on the first time-domain resource within a first time period related to the first measurement.

[0113] In some embodiments, the reference signal in the downlink can be an SSB, and accordingly, the first time window for measuring the SSB can be a synchronization signal block measurement timing configuration (SS / PBCH block Measurement Timing Configuration, SMTC) window.

[0114] In some embodiments, for different first measurements, different first conditions can be set in the second option A2. The first condition can include at least one of the following: the number of available reference signals within a second time period related to the first measurement reaches a first quantity threshold; the number of available first time windows within a third time period related to the first measurement reaches a second quantity threshold.

[0115] In some embodiments, the available first time window can refer to a first time window in which the number of available reference signals within the time window reaches a third quantity threshold. For example, a first time window in which there is at least 1 available reference signal can be regarded as an available first time window.

[0116] It should be noted that the first time period, the second time period, and the third time period related to the first measurement can be the same or different, and can be set for different first measurements.

[0117] The above respective quantity thresholds can be set according to actual needs, and different quantity thresholds can be set for different first measurement devices; or different quantity thresholds can also be set for different time periods; for example, the first quantity threshold can be determined based on a second time period; and the second quantity threshold can be determined based on a third time period.

[0118] In some embodiments, a layer 3 measurement L3 measurement is performed. Since a new radio UE only needs to detect / measure the downlink reference signal of the neighbor cell within the SMTC window, the network should ensure that the downlink reference signal within the SMTC window does not collide with any dynamic UL transmission of the UE, or if a collision occurs, the UE should prioritize the measurement of the downlink reference signal within the SMTC. The NR UE is only required to detect / measure the neighbor cell within the SMTC window, and therefore the network shall make sure that the SSB within the SMTC window would not be colliding with any dynamic UL for this specific UE, or if such colliding happens, the UE shall prioritize SSB measurement within SMTC.

[0119] In the resource management mode for layer 3 measurement, the first option A1 and / or the second option A2 can be included.

[0120] The first option A1 for layer 3 measurement can define that no uplink transmission is expected on the first time-domain resource within the first time window; and the first time window can be the SMTC window. The second option A2 can explicitly indicate that the first condition that needs to be met for performing the first measurement is that the number of available first time windows within a third time period related to the first measurement reaches a second quantity threshold.

[0121] The third time period can include at least one of the following: a reference signal synchronization delay period; a time index detection period; and a measurement period.

[0122] In some embodiments, different reference signals can correspond to different reference signal synchronization delay periods during the reference signal synchronization delay period; for example, the reference signal synchronization delay period can include: a primary synchronization signal (PSS) synchronization delay period (PSS sync); and / or, a secondary synchronization signal (SSS) synchronization delay period (SSS sync).

[0123] In some embodiments, the second quantity threshold can be determined by the third time period, that is, different second quantity thresholds can be set for different third time periods.

[0124] In some embodiments, a mapping table between the third time period and the second quantity threshold can be set, and the current second quantity threshold can be determined based on the current third time period by querying the mapping table. For example, as shown in Table 1:

[0125] Table 1

[0126] Wherein, w / o gap is used to represent that the corresponding third time period does not require a measurement gap.

[0127] In some embodiments, for layer 3 measurement:

[0128] A1. The scheduling / availability of the UE when performing measurements in HD-FDD bands can be defined: within a certain SMTC window, the UE should not transmit PUCCH / PUSCH / SRS on the RS symbols to be measured. Define Scheduling availability of UE performing measurements in HD-FDD bands: UE is not expected to transmit PUCCH / PUSCH / SRS on RS symbols to be measured in the certain SMTC window.

[0129] A2. It is clarified that the above measurement is only applicable for the case when the UE has X available SMTC windows during the period of T3. Clarify that the measurement requirements only applicable for the case when the X number of SMTC windows are available at the UE during the period of T3.

[0130] Wherein, X and T3 are associated, X is the required measurement samples for the specified T.

[0131] In some embodiments, for the first measurement for satellite switching, the switching can be satellite switching with re-synchronization for NTN system.

[0132] In some embodiments, based on different switching modes, the satellite switching can be divided into first satellite switching and second satellite switching, wherein the first satellite switching is satellite switching with hard switch, and the second satellite switching is satellite switching with soft switch.

[0133] The satellite switching with hard switch means that in the process of switching from the source satellite to the target satellite, the terminal first disconnects the connection with the source satellite, and then establishes the connection with the target satellite to complete the satellite switching. The satellite switching with soft switch means that in the process of switching from the source satellite to the target satellite, the terminal first establishes the connection with the target satellite, at this time, the terminal is connected with the source satellite and the target satellite at the same time, and then disconnects the connection with the source satellite to complete the satellite switching.

[0134] In some embodiments, for the first measurement for the first satellite switching, the corresponding resource management method can include a second option A2.

[0135] In some embodiments, the second option A2 corresponding to the first satellite switching can indicate that the first condition required to be met for performing the first measurement can be that the number of available reference signals (such as SSB) in a second time period corresponding to the first measurement reaches a first number threshold (such as 1). Wherein, the second time period can include at least one of the following: a time period TΔ for obtaining time fine synchronization in the first satellite switching; an interruption uncertainty period TIU for obtaining the first uplink transmission resource in the first satellite switching.

Wherein the first time period can include at least one of: a delay period of the second satellite switch; or a maximum value between t_service-t_serviceStart and Tsearch+TΔ+Tmargin.

[0141] Wherein the delay period of the second satellite switch can be expressed as Tsoft_switch=max(t_service-t_serviceStart,Tsearch+TΔ+Tmargin)+TIU+Tprocessing; wherein t_service indicates time information when the current NTN cell will stop providing service for the currently covered area, t_seviceStart indicates time information when the target satellite starts to provide service for the area covered by the current serving satellite, t_service-t_seviceStart represents the time interval between t_service and t_serviceStart; Tsearch represents the time required to search for the space-air-ground cell where the target satellite is located; TΔ represents a time period for obtaining time fine synchronization; Tmargin represents the post-processing time for the received reference signal, which can reach 2ms; TIU represents the interruption uncertainty period for obtaining the first uplink transmission resource; Tprocessing represents the UE processing time, which can reach 10ms.

[0142] In some embodiments, the second option A2 for the second satellite switch can indicate that the first condition that the first measurement requirement is satisfied can be that the number of available reference signals (e.g., SSB) reaches a first quantity threshold (e.g., 1) in a second time period corresponding to the first measurement. Wherein the second time period can include at least one of: a time period TΔ for obtaining time fine synchronization in the second satellite switch; an interruption uncertainty period TIU for obtaining the first uplink transmission resource in the second satellite switch.

For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, steps S201+S202 can be implemented as an independent embodiment, but not limited thereto.

[0209] In some embodiments, steps S201, S202 can exchange order or be executed simultaneously.

[0210] In some embodiments, step S201 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0211] In some embodiments, step S202 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0212] In some embodiments, other optional embodiments described before or after the description corresponding to FIG. 2 can be referred to.

[0213] In some embodiments, the related art does not define the wireless resource management request completely when the terminal performs NR NTN communication, so that the RS and uplink transmission configured for the terminal may conflict, and the mobile performance of the terminal cannot be guaranteed. Therefore, a wireless resource management method for the terminal when performing NR NTN communication is needed.

[0214] Embodiments of the present disclosure propose a resource management method. FIG. 3 is a schematic flowchart of a resource management method according to an embodiment of the present disclosure. The resource management method shown in the present embodiment can be performed by a terminal.

[0215] In some embodiments, the terminal can be a terminal that does not support full-duplex communication.

[0216] In some embodiments, the terminal can be a terminal for half-duplex HD communication.

[0217] In some embodiments, the terminal can be a terminal for half-duplex frequency division duplex HD-FDD communication.

[0218] In some embodiments, the terminal is a terminal that does not support full-duplex communication in NTN.

[0219] In some embodiments, the terminal can be a terminal for HD-FDD in NTN.

[0220] As shown in FIG. 3, the resource management method can include the following steps:

[0221] In step S301, in a first time domain resource for transmitting a reference signal for downlink, a second time domain resource that conflicts with uplink transmission is determined; wherein the reference signal is used for first measurement.

[0222] In some embodiments, after determining the first time domain resource for transmitting the reference signal related to the first measurement, the HD-FDD terminal can determine whether there is a second time domain resource that conflicts with the uplink transmission of the HD-FDD terminal in the first time domain resource.

[0223] In some embodiments, the HD-FDD terminal can determine whether the uplink transmission conflicts with the first time domain resource for transmitting the downlink reference signal related to the first measurement when determining that the uplink transmission is needed; if so, determine the second time domain resource in the first time domain resource that conflicts.

[0224] In some embodiments, the first measurement based on the downlink reference signal can also be referred to as downlink measurement.

[0225] In some embodiments, the first measurement can include layer 3 measurement L3 measurement and / or measurement for handover.

[0226] Wherein, the handover can include satellite switching and / or conditional switching.

[0227] In some embodiments, the uplink transmission of the terminal can include transmission of at least one of PUCCH, PUSCH, and SRS.

[0228] In step S302, the first measurement is preferentially ensured on the second time domain resource.

[0229] In some embodiments, the terminal can determine that there is a second time domain resource that conflicts with the uplink transmission in the first time domain resource for transmitting the downlink reference signal related to the first measurement, and can require that the first measurement be preferentially ensured on the second time domain resource, that is, the transmission of the downlink reference signal related to the first measurement is preferentially performed on the second time domain resource.

[0230] In some embodiments, the terminal can determine whether there is a RS symbol that conflicts with the uplink transmission in the RS symbol for transmitting the downlink reference signal related to the first measurement, and can require that the transmission of the downlink reference signal related to the first measurement be preferentially performed on the RS symbol that conflicts.

[0231] In some embodiments, the basic principle is to ensure the measurement opportunity based on the downlink reference signal, for example, for the HD-FDD terminal, the downlink measurement based on radio resource management is prior to the uplink transmission.

[0232] It should be noted that the embodiment shown in FIG. 3 can be independently implemented, or can be combined with at least one other embodiment of the present disclosure, which can be selected as needed, and the present disclosure is not limited.

[0233] In some embodiments, when the time domain resource for transmitting the downlink reference signal conflicts with the uplink transmission, the basic principle is to preferentially ensure the measurement corresponding to the reference signal to allocate the time domain resource that conflicts, thereby avoiding the conflict and improving the mobile performance of the terminal.

[0234] In some embodiments, the terminal can ensure the first measurement on the second time-domain resource based on a predefined resource management method. The predefined resource management method can be set by at least one of the following two options: a first option A1, which can define modulation restriction and / or availability of the resource, for example, define that the terminal does not expect to perform uplink transmission on the first time-domain resource used for transmitting the reference signal of the downlink; and a second option A2, which can explicitly indicate the first condition required to be met for performing the first measurement, which is equivalent to indicating the first condition required to be met for allowing uplink transmission, for example, the first measurement needs to be performed under the condition that the first condition is met, which is equivalent to allowing uplink transmission on the second time-domain resource after the first condition is met, that is, uplink transmission on the second time-domain resource can be allowed under the condition that it is determined that the uplink transmission on the second time-domain resource will not substantially affect the performance of the first measurement; wherein the first condition is used to indicate that the number of available reference signals in the time period related to the first measurement reaches a number threshold.

[0235] wherein the available reference signal can refer to a reference signal expected to be received, that is, a reference signal that can be received on a transmission occasion or time-domain resource without conflict, which can also be equivalent to the number of transmission occasions or time-domain resources without conflict.

[0236] In an implementation, the first option A1 can define that the terminal should not perform uplink transmission, such as PUCCH / PUSCH / SRS, on the RS symbol used for measurement.

[0237] In an implementation, the second option A2 can indicate that the first measurement is only applicable to the case where the number of SSBs available to the UE during the specific measurement period meets the requirement, wherein the specific measurement period is the time period related to the first measurement.

[0238] In some embodiments, different resource management methods, that is, different first options A1 and / or different second options A2, can be used for different first measurements.

[0239] In some embodiments, for different first measurements, the first option A1 can include at least one of the following: not expecting to perform uplink transmission on the first time-domain resource within a first time window, the first time window being a time window for measuring the reference signal; and not expecting to perform uplink transmission on the first time-domain resource within a first time period related to the first measurement.

[0240] In some embodiments, the reference signal of the downlink can be SSB, and accordingly, the first time window for measuring the SSB can be the SMTC window.

[0241] In some embodiments, different first conditions can be set in the second option A2 for different first measurements. The first conditions can include at least one of the following: the number of available reference signals in a second time period related to the first measurement reaches a first number threshold; the number of available first time windows in a third time period related to the first measurement reaches a second number threshold.

[0242] In some embodiments, the available first time window can refer to a first time window in which the number of available reference signals reaches a third number threshold. For example, a first time window in which there are at least 1 available reference signal can be taken as an available first time window.

[0243] The above-mentioned various number thresholds can be set according to actual needs, and different number thresholds can be set for different first measurement devices; or different number thresholds can also be set for different time periods; for example, in an implementation, the first number threshold can be determined based on the second time period; and the second number threshold can be determined based on the third time period.

[0244] In an implementation, the resource management manner for the layer 3 measurement L3 measurement can include the first option A1 and / or the second option A2.

[0245] In the first option A1 for the layer 3 measurement, it can be defined that no uplink transmission is expected on the first time-domain resource in the first time window; and the first time window can be the SMTC window.
