Detailed Description

The section headings used in this document are for ease of understanding only and do not limit the scope of the embodiments to the sections in which they are described. In addition, although embodiments are described with reference to the 5G example, the disclosed techniques may be applied to wireless systems using protocols other than the 5G or 3GPP protocols.

The development of a New generation of wireless communication, 5G New air interface (NR) communication, is part of a continuous mobile broadband evolution process for meeting the ever-increasing network demands. NR will provide greater throughput to allow more users to be connected simultaneously. Other aspects such as energy consumption, equipment cost, spectral efficiency and latency are also important to meet the needs of various communication scenarios.

SUMMARY

As wireless communication technologies develop, various wireless communication systems may have improved performance indicators, such as transmission rate, delay, throughput, reliability, and the like. However, to enable high performance wireless communications, the terminal may need to perform relatively complex processing tasks to meet performance requirements. For example, the terminal may detect a large control channel bandwidth, control information, data information encoding, decoding process, and the like. However, the terminal may consume power in performing these processing tasks, which may degrade the user experience. Accordingly, the present embodiments relate to reducing power consumption of a terminal in a wireless communication system.

In the development of wireless communication technology, it is an important consideration to save power consumption of a terminal and to achieve a balance between system performance and terminal power consumption on the premise of satisfying certain performance indexes. In many cases, the UE may not know whether the DCI has data scheduling in the current slot before blindly decoding the DCI, and thus the UE may need to continuously buffer data. Buffering data may not be needed since the current time slot may not have data scheduled, which may increase power consumption. The power saving technique may include signaling a minimum value of the K0/K2/a CSI-RS trigger offset to the UE. K0/k2, which the UE may not desire to be indicated, is a number less than the corresponding minimum value. The CSI-RS trigger offset may be implicitly indicated by a k0 minimum value. In this technique, indicating a minimum value greater than 0 may be equivalent to telling the UE that the DCI will not schedule data in the slot in which the PDCCH is transmitted, and the UE may not need to buffer the data, thereby saving power. Meanwhile, a minimum value greater than 0 may allow the UE to relax the processing timeline and may also save power.

However, there is no method for determining the minimum value of each parameter and there is no minimum action time, which may cause the minimum value to be inconsistent between the base station (e.g., the gNB) and the UE. For example, the base station may indicate to the UE that the minimum value is 1, but the UE may decode the indication information after 2 slots, and in both slots, the base station and the UE's understanding of the minimum value is inconsistent.

Overview of the System

This patent document relates to determining a minimum value, including determining a minimum value functioning delay, application range, and the like.

From the perspective of the base station, the base station may determine the minimum value of the set of parameters according to the first preset information and/or the higher layer configuration signaling. The base station may transmit the minimum value of the determined set of parameters to the UE.

The minimum value may be sent to the UE through layer 1 (L1) signaling (e.g., power saving signaling).

The minimum value of the set of parameters may include at least one of: a minimum value of K0 (K0 min), a minimum value of K2 (K2 min), a minimum value of aperiodic SRS offset (SRSmin), a minimum value of slot offset between DCI triggering aperiodic sounding reference signal and associated aperiodic channel state information reference signal (offset-CSI-min), a minimum value of K1 (K1 min), a minimum value of aperiodic CSI-RS offset (a CSI-RSmin/aperiodic CSI-RSmin).

The aperiodic CSI-RS offset may include a slot offset between a set of triggering downlink control information and aperiodic non-zero power channel state information reference signal (NZP CSI-RS) resources. The aperiodic SRS offset may include an offset that triggers multiple slots between the DCI and the actual transmission of this SRS-ResourceSet.

K0 may include an offset between the DCI and its scheduled PDSCH. K2 may include a slot offset between DCI and its scheduled PUSCH. K1 may include a slot offset between PDSCH and DL ACK or a slot offset between DCI and HARQ. K1 may include a value indicated in a PDSCH-to-HARQ timing indicator field in a DCI format.

The present embodiment may include determining a minimum contribution delay (action delay). The base station may determine a minimum active delay Thred1 according to the second preset information, and the minimum value of the set of parameters transmitted to the UE may be validated/applied after Thred1. Thread 1 may comprise an integer greater than or equal to 0, and the unit of thread 1 is a slot, symbol, or millisecond.

In some embodiments, the second preset information is a (related) parameter indicating the resource, and is at least one of: the number of physical resource blocks in the frequency domain, a bandwidth part index (BWP ID), a control resource group index (CORESET ID), a subcarrier spacing (SCS), carrier aggregation, a frequency range type (FR type), a rank indication value (RI), a number of antenna ports (Port), a precoding codebook index (PMI).

In some embodiments, the second preset information is a frequency range type. Thread 1 may equal F1 if the frequency range type is FR1, otherwise thread 1 may equal F2. F1 and F2 may be integers greater than 1, and F1 is less than F2.

In a further embodiment, the second preset information is carrier aggregation. Thred1 is equal to the minimum time for cross-carrier scheduling if the DCI indicating the minimum value also indicates cross-carrier scheduling.

In a further embodiment, the second preset information is a parameter of the control information and is at least one of: search space, user equipment identity, parameters in Downlink Control Information (DCI) field.

In some embodiments, the second preset information is a parameter in a DCI field. If a parameter in the DCI field is associated with an active delay, then Thred1 is associated with the active delay. Alternatively, thred1 equals the active delay.

In further embodiments, the second preset information refers to (related) parameters of the reference signal and is at least one of: channel state information reference signals (CSI-RS), demodulation reference signals (DMRS), hybrid automatic repeat request acknowledgement signals (HARQ-ACK), tracking Reference Signals (TRS), sounding Reference Signals (SRS).

In certain embodiments, thred1 is equal to the slot offset of the aperiodic CSI-RS or aperiodic SRS if the DCI indicating the minimum value also triggers the aperiodic CSI-RS or aperiodic SRS.

In further embodiments, the second preset information may refer to indication signaling and is at least one of: radio resource control layer control signaling or layer 3 signaling, intermediate access control layer control information or layer 2 signaling, downlink control information or layer 1 signaling. In some embodiments, the signaling may indicate a value of thread 1. In further embodiments, threaded 1 may be equal to the active delay of one of the signalings.

In further embodiments, the second preset information may be group-specific, wherein a terminal in the group refers to a plurality of base stations according to a parameter related to the terminal (e.g., UE). The terminals (e.g., UEs) may be divided into groups and the parameters related to the terminals (e.g., UEs) include one of: terminal or UE identification information (UE ID), cell radio network temporary identification number (C-RNTI), priority of service type. In certain embodiments, the value of thread 1 is different for different groups.

The minimum value may be sent to the UE through L1 (layer 1) signaling, where the L1 signaling may include a minimum value (minimum value of the set of parameters) indication. In some embodiments, the L1 signaling is power save signaling. The power saving signaling may be signaling that includes parameters for the UE power saving technology. The power saving signaling may be at least one of: new format DCI, enhancements to existing scheduled DCI formats with additional field(s) (e.g., DCI format 0_0, DCI format 0_1, DCI format 1_0, DCI format 1_1), enhancements to existing scheduled DCI formats that reuse existing field(s).

In some embodiments, the minimum value may be indicated by M bits in one field of L1 (layer 1) signaling. If M =1, one state of the bit field may indicate that all minimum values are 0, and another state may indicate that all minimum values are equal to I1. I1 may be a positive integer greater than or equal to 1; if M is greater than 1, the L1 signaling may include the minimum value of each parameter or an index of the minimum value of each parameter.

The minimum value of the above-described parameters (the minimum value of the set of parameters) may be implicitly indicated. The minimum value of the first parameter may be implicitly indicated by signaling indicating the minimum value of the second parameter. The implicit indication may include that the minimum value of the first parameter is not present, and in some embodiments the signaling indicating the minimum value of the second parameter may simultaneously indicate the validity of a default minimum value of the first parameter, in some embodiments the minimum value of the first parameter is equal to the minimum value of the second parameter, in other embodiments the minimum value of the first parameter is shifted by the minimum value of the second parameter.

The first preset information may include at least one of: bandwidth part index (BWP ID), UE assistance information, discontinuous Reception (DRX) status (e.g., outside or within active time), UE capability information, terminal type, subcarrier spacing (SCS), a set of configured time domain resources.

The Discontinuous Reception (DRX) state may include a state outside an active time (inactive state) and a state within the active time (active state), where the active time is a total duration for which the UE listens to the PDCCH. This includes the "on duration" of the DRX cycle, the time the UE performs continuous reception when the inactivity timer has not expired, and the time the UE performs continuous reception while waiting for a retransmission opportunity. The UE does not need to listen to the PDCCH outside of the activation time.

The second preset information may include UE assistance information, wherein the UE assistance information may include a Time1 for decoding DCI reported by the UE, and the effective delay Thred1 may be determined according to the decoding DCI Time. The time for decoding DCI may include a time for processing a Physical Downlink Control Channel (PDCCH) or a time for decoding the PDCCH or a time for decoding DCI. In some embodiments, thred1 may be greater than or equal to Time1, and Thred1 may be equal to 1 if the UE does not report Time1 for decoding DCI or the minimum value of the slots applied for power saving signaling is equal to 0 or the minimum value of the slots receiving power saving signaling is not applied. The time for decoding the DCI may include a time for the UE to decode the DCI when a minimum value of all the parameters is greater than zero.

The second preset information may include UE capability, wherein the UE capability may include Time/capability Time2 for decoding DCI reported by the UE, and the acting delay Thred1 may be determined according to the Time/capability for decoding DCI. In some embodiments, thred1 may be greater than or equal to Time2, and Thred1 may be equal to 1 if the UE does not report Time/capability Time2 for decoding DCI or the minimum value of Time slots applied for receiving power saving signaling is equal to 0 or the minimum value of Time slots applied for receiving power saving signaling is not applied. The time/capability for decoding DCI may include a UE time/capability for decoding DCI when a minimum value of all parameters is greater than zero.

The second preset information may include a minimum value (latest minimum value) to be acted upon/applied by the UE before transmitting the power saving signaling including the minimum value indication. Thred1 may be equal to N1 if there is at least one previously applied minimum value greater than the corresponding minimum value indicated by the power saving signaling (e.g., previously active k0min is greater than the indicated k0 min). Otherwise, thred1 may be equal to N2. Thred1 may be equal to N3 if a minimum value has not been previously indicated. N1 may be a positive integer greater than or equal to 1, N2 and N3 may be integers greater than or equal to 0, optionally, N3= N2. Alternatively, N1 may be equal to k0min. Alternatively, N1 may be equal to N2. Optionally, N1 is associated with a time for decoding DCI.

The second preset information may comprise a minimum value to be acted upon/applied by the UE before transmitting the power saving signalling comprising an indication of the minimum value. Thread 1 may be equal to N1 if the previously applied k0min is greater than k0min indicated by the power saving signaling. Otherwise, thred1 may be equal to N2. Alternatively, thred1 may be equal to N3 if the minimum value has not been previously indicated. N1 may be a positive integer greater than or equal to 1, N2 and N3 may be integers greater than or equal to 0, optionally, N3= N2. Alternatively, N1 may be equal to k0min. Alternatively, N1 may be equal to N2. Optionally, N1 is associated with a time for decoding DCI.

The minimum value for each BWP may be obtained by formulaic transformation (UE with a set of minimum values)

The minimum value (e.g., k0min/k2min/k1 min/SRSmin/offset-csi-min) may be indicated as a configuration on the active BWP, while the minimum value on BWP (i) (e.g., k0min (i)/k 2min (i)/k 1min (i)/SRSmin (i)/offset-csi-min (i)) may be configured simultaneously. The minimum value may be determined by the converted active BWP minimum value (indicated at k0min/k2min/k1 min/SRSmin/offset-csi-min). The conversion relationship is that Kmin (i) may be equal to operation (Kmin, m), where Kmin may be one of: k0min, k2min, k1min, SRSmin, offset-csi-min, where m may comprise a real number and the operation may be a multiplication or addition operation.

M described above may be related to at least one of: BWP SCS and/or time-domain resources (timedomainallclositionlist TDRA) configured on BWP. The TDRA may include a PDSCH-TDRA and a PUSCH-TDRA. The PDSCH-TDRA may include higher layer configuration or default tables. Each row (index) in the table may correspond to a set of parameters (k 0, etc.). The DCI with data scheduling may contain a field indicating an index of the TDRA, and the index value may indicate a k0 value. The PUSCH-TDRA may include a higher layer configuration or default table. Each row (index) in the table may correspond to a set of parameters (k 2, etc.). The DCI with data scheduling may contain a field indicating an index of the TDRA, and the index value may indicate a k2 value.

In the cross-carrier scheduling mode, the minimum value of the set of parameters may be indicated on a scheduling component carrier (scheduling CC), and the minimum value of the scheduled component carrier (scheduling CC) may be implicitly indicated according to the minimum value on the scheduling component carrier.

The minimum value of K1 may be tied to other parameters. The minimum value (K1 min) indication may be applied at least to Downlink Control Information (DCI) requiring hybrid automatic repeat request acknowledgement (HARQ-ACK) information. K1min may be implicitly indicated by the minimum value of the other parameter described above, which implies that K1min is equal to the minimum value of the other parameter. (example: k1min = k0 min).

Membership between aperiodic SRS and aperiodic CSI-RS. A minimum value (offset-CSI-min) of a gap between a DCI triggering an aperiodic SRS and an associated aperiodic channel state information reference signal (a CSI-RS) may be implicitly indicated by another minimum value in the set of parameters (e.g., offset-CSI-min = k0 min). An aperiodic CSI-RS (channel state information reference signal) associated with the aperiodic SRS may be received at least offset-CSI-min units after receiving DCI triggering the aperiodic SRS. offset-csi-min may be an integer greater than or equal to 0 and the unit may be a slot, a millisecond, or a symbol.

The parameter (offset-CSI) indicating the offset between the DCI triggering the aperiodic sounding reference signal (aperiodic SRS) and the associated aperiodic CSI-RS may be configured by RRC (radio resource control), and if not present, the default value may be 0.

The parameter (offset-CSI) triggering the offset between the DCI of the aperiodic sounding reference signal (aperiodic SRS) and the associated aperiodic CSI-RS can be reinterpreted by the minimum value of one parameter. Reinterpretation may mean that the parameter value is reset to equal the minimum value (e.g., offset-csi = k0 min).

The method may further include the base station determining an applicable (valid) range of the minimum value based on the determined minimum value and/or the second higher layer configuration information.

From the terminal's perspective, the terminal (or UE) may receive L1 signaling (e.g., power save signaling) from the base station and indicate a minimum value for a set of parameters. The minimum value may be determined by the first preset information and/or the higher layer configuration information.

The method may include the minimum value taking effect after receiving Thred1 units of L1 signaling, thred1 may include an integer greater than or equal to 0, and the units of Thred1 may be slots or symbols or milliseconds. Thread 1 may be determined by the base station according to the second preset information.

The power saving signaling received by the UE includes M bits in one field of the signaling and indicates a minimum value of a set of parameters. If M =1, one state of the bit field may indicate that all minimum values are 0, and another state may indicate that all minimum values are equal to I1. I1 may be a positive integer greater than or equal to 1; if M is greater than 1, the L1 signaling may include an index to the value of each parameter or the minimum value of each parameter.

The minimum value of the above-described parameters (the minimum value of the set of parameters) may be implicitly indicated. The minimum value of the first parameter may be implicitly indicated by signaling indicating a minimum value of the second parameter. The implicit indication may include that the minimum value of the first parameter is not present, and in some embodiments the signaling indicating the minimum value of the second parameter may simultaneously indicate the validity of a default minimum value of the first parameter, in some embodiments the minimum value of the first parameter is equal to the minimum value of the second parameter, in other embodiments the minimum value of the first parameter is shifted by the minimum value of the second parameter.

The first preset information may include at least one of: BWP ID, UE assistance information, discontinuous Reception (DRX) status (e.g., outside or within active time), UE capability information, terminal type, subcarrier spacing (SCS), a set of configured time domain resources.

The second preset information may include UE assistance information or UE capability information, wherein the UE assistance information or UE capability information may include a Time1 for decoding DCI reported by the UE, and the acting delay Thred1 may be determined according to the decoding DCI Time. In some embodiments, thred1 may be greater than or equal to Time1, and Thred1 may be equal to 1 if the UE does not report Time1 for decoding DCI or the minimum value of the Time slots applied for receiving power saving signaling is equal to 0 or the minimum value of the Time slots applied for receiving power saving signaling is not applied. The time for decoding the DCI may include a time for the UE to decode the DCI when a minimum value of all the parameters is greater than zero.

The second preset information may include the latest minimum value. Thred1 may be equal to N1 if there is at least one previously applied minimum value greater than the corresponding minimum value indicated by the power saving signaling (e.g., previously functional k0min is greater than the indicated k0 min). Otherwise, thred1 may be equal to N2. Thred1 may be equal to N3 if a minimum value has not been previously indicated. N1 may be a positive integer greater than or equal to 1, N2 and N3 may be integers greater than or equal to 0, optionally, N3= N2. Alternatively, N1 may be equal to k0min. Alternatively, N1 may be equal to N2. Optionally, N1 is associated with a time for decoding DCI.

The minimum value (k 0min/k2min/k1min/SRS min/offset-CSI-min) may be indicated as a configuration on active BWP (a), and then the minimum value (k 0min (i)/k 2min (i)/k 1min (i)/SRSmin (i)/offset-CSI-min (i)) on BWP (i) may be determined by converting from the minimum value indicated on BWP (a). The conversion relationship is that Kmin (i) may be equal to operation (Kmin, m), where Kmin may be one of: k0min, k2min, k1min, SRSmin, offset-csi-min, where m may comprise a real number and the operation may be a multiplication or an addition operation.

M described above may be related to at least one of: the time domain resources on BWP SCS and BWP configure TimeDomainAllocationList (TDRA).

In the cross-carrier scheduling mode, the minimum value of the set of parameters may be indicated on the scheduling component carrier (scheduling CC), and the minimum value of the scheduled component carrier (scheduled CC) may be implicitly indicated according to the minimum value on the scheduling component carrier.

The minimum value (K1 min) may be applied at least to DCI requiring HARQ-ACK information. K1min may be implicitly indicated by the minimum value of the other parameter described above, an implicit indication meaning that K1min is equal to the minimum value of the other parameter. (example: k1min = k0 min).

A minimum value of an interval between a DCI triggering aperiodic SRS and an associated aperiodic CSI-RS (offset-CSI-min) may be implicitly indicated by another minimum value of the parameter set (e.g., offset-CSI-min = k0 min). The aperiodic CSI-RS associated with the aperiodic SRS may be received at least offset-CSI-min units after receiving the DCI triggering the aperiodic SRS. offset-csi-min may be an integer greater than or equal to 0 and the unit may be a slot, a millisecond, or a symbol.

A parameter (offset-CSI) indicating an offset between DCI triggering aperiodic SRS and an associated aperiodic CSI-RS may be configured by RRC, and if not present, a default value may be 0.

The parameter (offset-CSI) indicating the offset between the DCI triggering the aperiodic SRS and the associated aperiodic CSI-RS may be reinterpreted by the minimum value of one parameter (e.g., offset-CSI = k0 min).

The method may comprise the terminal determining an applicable (valid) range of minimum values based on the minimum values indicated by the signalling and/or the second higher layer configuration information.

If the minimum value received by the terminal is 0, the minimum value may have no invalid range. Otherwise, the terminal may determine the minimum application range in combination with the higher layer configuration information.

The second higher layer configuration information may include at least one of: search space, radio Network Temporary Identifier (RNTI), PDSCH-timedomainnalockionist (PDSCH-TDRA), PUSCH-timedomainnalockionist (PUSCH-TDRA), time domain resource, frequency domain resource, type of downlink control information.

The higher layer configuration information may include PDSCH-TDRA, and the terminal may determine an applicable (valid) range of the minimum value according to the minimum value indicated by the signaling and the higher layer configuration information. If the higher layer is not configured with a pdsch-TDRA or if the higher layer is configured with a pdsch-TDRA and the number of terms where k0 is greater than or equal to k0min is less than or equal to Thred3, the minimum value will be invalid (not applicable/invalid), where Thred3 can be an integer greater than or equal to 0 and less than or equal to 8. Otherwise, the minimum value may be valid.

The higher layer configuration information may include PUSCH-TDRA, and the terminal may determine an applicable (valid) range of the minimum value according to the minimum value indicated by the signaling and the higher layer configuration information. If the higher layer is not configured with a pusch-TDRA or the higher layer is configured with a pusch-TDRA and the number of terms where k2 is greater than or equal to k2min is less than or equal to Thred4, the minimum value will be invalid (not applicable/invalid), where Thred4 can be an integer greater than or equal to 0 and less than or equal to 8. Otherwise, the minimum value may be valid.

A method may also include the UE reporting a decode DCI time/capability, where the decode DCI time/capability is a time that the UE uses to decode DCI and the decode DCI time/capability unit is a slot or symbol or millisecond. The default value for the decode DCI time may be less than 1 slot if the UE does not report a decode DCI capability.

Example embodiment 0

Example embodiment 0 may involve minimum value setting of various setting values, delay in functioning, and the like.

The base station may determine a minimum value of a set of parameters according to the first preset information and/or a higher layer configuration signaling (higher layer configuration information), and the base station may send the determined minimum value of the set of parameters to the UE through the power saving signaling.

High layer configuration signaling

The higher layer configuration signaling may indicate an optional value for the minimum value of each parameter.

If the higher layer configuration signaling is configured and the minimum value indicated by the first preset information is within the selectable values indicated by the higher layer configuration signaling, the minimum value may be configured according to the value indicated by the first preset information. If the higher layer configuration signaling is configured and the minimum value indicated by the first preset information is not within the selectable values indicated by the higher layer configuration signaling, the minimum value may be configured according to the value indicated by the higher layer configuration signaling. If the high-layer configuration signaling is not configured, the minimum value of each parameter can be determined according to the first preset information. Otherwise, the minimum value of each parameter may be determined according to higher layer configuration signaling.

First preset information

Alternatively, the first preset information may include a DRX state in which the UE is located, and the DRX state may be a state outside an active time (outside an inactive state/active state) and a state within the active time (active state), where the active time is a total duration for which the UE listens to the PDCCH. This includes the "on duration" of the DRX cycle, the time the UE performs continuous reception when the inactivity timer has not expired, and the time the UE performs continuous reception while waiting for a retransmission opportunity. The UE does not need to listen to the PDCCH outside of the activation time.

Optionally, the minimum value of any one of the set of parameters configured outside the activation time may be a value of a first set of minimum values, the minimum value of any one of the set of parameters configured within the activation time may be a value of a second set of minimum values, and the first set of minimum values may be different from the second set of minimum values. For example, the first set of minimum values may include integers ranging from greater than or equal to 0 to less than or equal to M1, and the second set of minimum values may include integers ranging from greater than or equal to 0 to less than or equal to M2. Alternatively, M1 may be equal to 1, and alternatively, M2 may be equal to 24.

In other words, each minimum value of the active state (or within the active time) and the inactive state (or the inactive state outside the active time) may have a different range of values. The minimum value of k0 outside the activation state may range from greater than or equal to 0 to less than or equal to M1, and the minimum value of k0 within the activation state may range from greater than or equal to 0 to less than or equal to M2. Alternatively, M1 may be equal to 1, and alternatively, M2 may be equal to 24.

Alternatively, the set of minimum values for each parameter configured by the higher layer configuration information may be different minimum values for outside of the activation time and for within the activation time. The higher layer configuration signaling may be different for the outside of the activation time and for the inside of the activation time. For example, outside the activation time, higher layer configuration signaling (e.g., RRC signaling) indicates a set of minimum values. During the activation time, higher layer configuration signaling (e.g., RRC signaling) may indicate multiple sets of minimum values.

Alternatively, power save signaling within the active or inactive state may use a different number of bits in the field to indicate the minimum value of a set of parameters. In the inactive state, the power saving signaling may use M3 bits to indicate the minimum value, and in the active state, the power saving signaling may use M4 bits to indicate the minimum value. In one embodiment, M3 may be equal to 1 and one state of the bit field may represent all minimums as 0 while another state is all minimums equal to I1, I1 may be a positive integer greater than or equal to 1.

In other embodiments, I1 may be equal to a default minimum value, where the default minimum value is configured by RRC. Optionally, I1 may be configured by RRC configuration. Optionally, the power saving signaling in the active state may use M4 bits in the field to indicate a minimum value, optionally, M4= Num2, where Num2 may be a positive integer greater than or equal to 2 and less than or equal to 8, and the power saving signaling may indicate the minimum value or an index of the minimum value of each parameter. Alternatively, num2 is determined by the number of minima or the number of indices of a set of minima (e.g., the minimum set index number is 32, then Num2= log ₂ 32＝5)。

Alternatively, the minimum value indicated by power saving signalling in the active state may be related to the minimum value indicated by power saving signalling other than in the active state. The minimum value indicated by the power saving signalling in the active state may be greater than or equal to the minimum value indicated by the power saving signalling outside the active state. For example, power save signaling outside of the active state may use 1 bit in the field to indicate the minimum value, state "0" indicating that the minimum value is 0, and state "1" indicating that the minimum value is a default value, where the default value is I2, and I2 is an integer greater than or equal to 1. If the power saving signaling outside the active state indicates a minimum value of 0, the minimum value indicated by the power saving signaling in the active time may be greater than or equal to 0 in the corresponding DRX cycle. Otherwise, the minimum value indicated by the power saving signaling in the activation time may be greater than or equal to I2.

Alternatively, the default minimum value may be 0 if no minimum value is indicated outside the activation time.

Alternatively, the minimum value of a part of the parameters may be indicated other than the activation time, and the minimum values of the other parameters are implicitly indicated by the minimum value of the part of the parameters. For example, the outside of the activation time indicates only K0min, then K1min = K0min, K2min = K0min + deta, where deta may be an integer greater than or equal to 0, SRSmin = K0min.

Alternatively, the first preset information may be a subcarrier spacing. The maximum possible value of the minimum value of each parameter may increase with increasing subcarrier spacing. For example, SCS =15kHz, the minimum value of the parameter k0 has a maximum value of 2. In this example, the maximum value of the minimum value of the parameter k0 is 6 when SCS =120 kHz.

Alternatively, the first preset information may be UE assistance information and the high layer configuration signaling may be a minimum selectable set of each parameter. The UE assistance information may be an expected minimum of parameters reported by the UE. The base station may determine a minimum value for each parameter by combining the UE assistance information and the higher layer configuration information. For example, the UE reports that the expected k0min is I3 and the optional set of k0min indicated by the higher layer configuration signaling comprises I3, then k0min = I3. If the selectable set of k0min indicated by the higher layer configuration signaling does not include I3, then k0min is determined according to the higher layer configuration, where I3 is an integer greater than or equal to zero.

Alternatively, the first preset information may be configured time domain resource group (PDSCH-TDRA, PUSCH-TDRA), and the determination of K0min may need to satisfy condition 1, where condition 1 is the number of entries in PDSCH-TDRA where K0 is greater than or equal to K0min, and the number of entries may be greater than Thred3, where Thred3 may be an integer greater than or equal to 0 and less than or equal to 8. The determination of K2min may require that condition 2 be satisfied, where condition 2 is that the number of K2 terms in the PUSCH-TDRA that are greater than or equal to K2min is greater than Thred4, where Thred4 may be an integer greater than or equal to 0 and less than or equal to 8.

Optionally, the first preset information may include a UE type. If the UE is of the NR light (lite) type, the minimum value may be greater than or equal to 1 and less than or equal to M5. Otherwise, the minimum value may be greater than or equal to 0 and less than or equal to M5, and M5 may be a positive integer less than or equal to 32.

Alternatively, the first preset information may be UE capability. If the UE may be configured with a minimum value greater than zero, the minimum value may be greater than or equal to 1 and less than or equal to M5. Otherwise, the minimum value may be greater than or equal to 0 and less than or equal to M5, and M5 may be a positive integer less than or equal to 32.

Minimum value of a set of parameters

The minimum value of the set of parameters may include at least a minimum value of the parameter K0 and/or a minimum value of the parameter K2. Alternatively, if a minimum value of the first parameter is not indicated, it may be implicitly indicated by a minimum value of the second parameter. An implicit indication is that if the first minimum value may not be transmitted and the second minimum value is transmitted, in some embodiments the first minimum value may be equal to the second minimum value (e.g., K1min = K2min, SRSmin = K2min, if the base station does not transmit K1min and/or SRS minimum). In other embodiments, the minimum value of the first parameter is converted by a second minimum value (e.g., k2min is not sent, then k2min = k0min + DETA, where DETA is an integer greater than or equal to 0). Optionally, SRSmin is associated with k0min, e.g., SRSmin = k0min + S1, where S1 is an integer greater than zero.

Action Delay (Action Delay)

The base station may determine the activation delay Thred1 according to the second preset information, and after the time of Thred1, a set of minimum values through the power saving signaling transmission is validated. Thred1 may be an integer greater than or equal to 0, and the unit of Thred1 may be a slot, a symbol, or a millisecond.

In other words, before slot n + Thred1, the UE may receive signaling indicating the minimum value in slot n, but the minimum value indicated by the signaling is invalid, and the UE may not expect to receive scheduling signaling indicating a k0 value greater than k0min before slot n-1.

The second preset information may include at least one of: SCS, BWP switching time, UE assistance information, applying a minimum in a slot before transmitting power saving signaling indicating a minimum (latest minimum), delay of other power saving technology information, UE capability.

Alternatively, the second preset information may be a minimum value effective before a set of minimum values indicated by the power saving signaling, and Thred1= N1 if the minimum value effective before the signaling is greater than the corresponding minimum value indicated by the signaling, otherwise Thred1= N2. Alternatively, if the minimum value was not previously indicated, thred1= N3. N1 may be a positive integer greater than or equal to 1, and N2 and N3 are integers greater than or equal to 0, optionally, N3= N2. Optionally, N1= k0min. Optionally, N1= N2. Optionally, N1 is associated with a time for decoding DCI.

Optionally, the second preset information may comprise a minimum value to be acted upon/applied by the UE before transmitting the power saving signalling comprising an indication of the minimum value. Thread 1 may be equal to N1 if the previously applied k0min is greater than k0min indicated by the power saving signaling. Otherwise, thred1 may be equal to N2. Thred1 may be equal to N3 if a minimum value has not been previously indicated. N1 may be a positive integer greater than or equal to 1, N2 and N3 may be integers greater than or equal to 0, optionally, N3= N2. Alternatively, N1 may be equal to k0min. Alternatively, N1 may be equal to N2. Optionally, N1 is associated with a time for decoding DCI.

Optionally, the second preset information is UE assistance information. Alternatively, the UE assistance information may be a decoded DCI Time1 reported by the UE, and Thred1 may be greater than or equal to Time1. If the UE does not report a decoded DCI Time1 or the minimum value applied in the slot in which the power save signaling is received is equal to 0, or the UE may not be configured with a set of minimum values before receiving the power save signaling, thred1 may be equal to T1, and T1 may be an integer greater than or equal to 0 (e.g., T1= 1). Alternatively, the UE assistance information may be a preset power saving level, and different power saving levels may correspond to different activation delays Thred1. For example, the power saving levels are divided into modeA and modeB. Where modeA corresponds to threaded 1= S3 and ModeB may correspond to threaded 1= S4. Wherein S1 and S2 may be integers greater than or equal to 0.

Alternatively, the UE capability may be a preset power saving level reported by the UE, and different power saving levels may correspond to different activation delays Thred1. For example, the power saving levels are divided into modeA and modeB. Where modeA corresponds to threaded 1= S3 and ModeB may correspond to threaded 1= S4. Wherein S1 and S2 may be integers greater than or equal to 0.

Alternatively, the second preset information may be a minimum value that is effective before receiving the power saving signaling and the slot of the subcarrier spacing (SCS). If the at least one parameter in effect prior to the time slot at which the power saving signaling is received is greater than the corresponding minimum value indicated in the power saving signaling, then a minimum contributing delay, thred1, of the minimum value indicated by the signaling can be determined from the SCS of the PDCCH indicating the minimum value (e.g., SCS =15kHz, thred1= S1; SCS =120kHz, thred1= S2, and S1 and S2 are integers greater than or equal to 0, S1< S2), where the configuration of the SCS and Thred1 relationship is configured by RRC; otherwise, thred1=1.

Alternatively, the second preset information may be a BWP switching time, and the minimum acting delay Thred1 may be less than or equal to the BWP switching time.

Alternatively, the second preset information may be a BWP handover time, and if the DCI indicates a set of minimum values and simultaneously triggers BWP handover, thred1 is equal to the BWP handover delay.

Alternatively, the second preset information may be subcarrier spacing (SCS) and UE assistance information or UE capability information. If the UE reports a decoded DCI time, thred1 is greater than or equal to the reported decoded DCI time; otherwise, thred1 may be determined from SCS (e.g., SCS =15kHz, then Thred1=1, SCS =120khz, then Thred1= 3), where the configuration of the relationship of Thred1 and SCS is RRC configuration.

Alternatively, the second preset information may be an active delay of the power saving signaling indicating a set minimum value, and the active delay of the minimum value is less than or equal to the active delay of the signaling.

Alternatively, the second information may indicate a functioning delay of the MIMO layer parameter. The minimum active delay may be related to the active delay of the MIMO layer parameters if the signaling indicating the minimum indicates the number of MIMO layers at the same time. Optionally, the contribution delay of the minimum value is equal to max (contribution delay of the minimum value, contribution delay of the MIMO layer parameters). Alternatively, the latency of functioning of the minimum value may be equal to the latency of functioning of the MIMO layer parameters. Optionally, the contribution delay of the minimum value is equal to min (contribution delay of the minimum value, contribution delay of MIMO layer parameters).

Alternatively, the second preset information may be an active delay of other power saving technology information. If the signaling indicating the minimum value indicates other power saving technology information parameters (e.g., wake up indication, MIMO parameters, PDCCH listening period, PDCCH hopping, SCell, BWP handover) at the same time, the minimum functioning delay may be determined from the functioning delays of the other power saving information parameters. Alternatively, the active delay of the minimum value may be equal to one of the active delays of the other power saving technical parameters. Alternatively, the contribution delay of the minimum value may be less than or equal to max (contribution delay of the minimum value, contribution delay of other power saving information). Alternatively, the latency of functioning of the minimum value may be equal to max (latency of functioning of the minimum value, latency of functioning of other power saving information).

If the parameter value is less than the corresponding minimum value, the minimum value of the parameter may be used to reinterpret the parameter value. Reinterpretation may be that the value of the parameter may be reset to be equal to the corresponding minimum value. For example: the DCI triggers the aperiodic SRS resource group. And the parameter of the aperiodic SRS offset is smaller than the minimum value of the aperiodic SRS offset, the aperiodic SRS offset is reinterpreted as the minimum value of the aperiodic SRS offset. The aperiodic SRS offset is an offset that triggers multiple slots between DCI and the actual transmission of this SRS-ResourceSet.

Example embodiment 1

The first example embodiment may relate to BWP minimum setting. Alternatively, the base station may determine a set of minimum values according to the higher layer configuration signaling and/or the first preset information, and transmit the set of minimum values to the UE by using the power saving signaling. A minimum value (k 0min/k2min/k1min/SRS min/offset-CSI-min) of the set of parameters may indicate a configuration on an active BWP, and a minimum value (k 0min (i)/k 2min (i)/k 1min (i)/SRSmin (i)) on another BWP configured by the UE is an implicit indication obtained by converting the minimum value of the BWP, wherein the conversion is Kmin (i) = Operation (Kmin, m), wherein Kmin is one of: k0min, k2min, k1min, SRSmin, offset-csi-min, kmin (i) is one of the following: k0min (i), k2min (i), k1min (i), SRSmin (i), offset-csi-min (i), where m is a real number, and the operation may be a multiplication operation or an addition operation (Kmin (i) = Kmin × m, kmin (i) = Kmin + m).

Alternatively, m may be associated with the SCS of BWP (e.g.,

)。

alternatively, the m value may be associated with a time domain resource configuration TDRA (timedomainallyconstatilist) on BWP. (for example,

where min (k 0/or k 2) (BWP (i)) represents the minimum k0 or minimum k2 value in the TDRA configured on BWP (i).

Alternatively, m may be a set of optional values configured by RRC.

Alternatively, the minimum value of a set of parameters that the base station determines and sends to the UE may be configured for each UE, in other words, the minimum value of any BWP configured for one UE is the same value. If the number of entries in PDSCH-TDRA configured on BWP (i) where k0 is greater than or equal to k0min is less than or equal to N1, where N1 may be a positive integer less than 10, or the number of entries in PUSCH-TDRA configured on BWP (i) where k2 is greater than or equal to k2min is less than or equal to N2, where N2 may be a positive integer less than 10, then in some embodiments the indicated minimum value is a no function indication (invalid). In some embodiments, the indicated minimum value is an inactive indication (invalid), and the minimum value for each parameter may be set to 0. In some embodiments, the UE may send a request to the base station to resend the new set of minimum values. In some embodiments, the base station may not schedule data on BWP (i). In some embodiments, a new set of minimum values is indicated in the DCI triggering BWP (i), wherein the new set of minimum values includes a new k2min, and the number of entries in the PUSCH-TDRA configured on BWP (i) that may be greater than or equal to k2min is greater than N2 and/or a new k0min, and the number of entries in the PDSCH-TDRA configured on BWP (i) that may be greater than or equal to k0min is greater than N1. In other embodiments, the base station may indicate a new set of minimum values after switching to BWP (i).

The base station may determine a set of minimum values according to the first preset information and/or the high layer configuration signaling, and the base station may transmit the set of minimum values to the UE.

The minimum value may be sent to the UE through L1 signaling (e.g., power saving signaling).

Alternatively, when a BWP handover occurs (e.g., BWP0 switches to BWP 1), if the BWP handover is based on a media access control element (MAC CE) indication or the BWP inactivity timer expires, or the BWP handover is based on a DCI trigger, and the DCI does not indicate a new set of minimum values,

the set of minimum values on the new BWP may be set to one of:

after switching BWP, a new set of minimums is transmitted by the base station in the nth slot. N may be a positive integer greater than or equal to 1. The set of minimum values for each parameter that can be applied is 0 before the new set of minimum values is applied.

After switching BWP, the default set of minimums is valid if BWP is configured with the default set of minimums. Otherwise, the minimum value may be 0.

Optionally, when a BWP handover occurs (e.g. BWP0 switches to BWP 1), if the DCI indicates BWP handover in the slot and no new minimum or indicated set of minimum values apply, then in some embodiments the contribution delay of the minimum is less than or equal to the BWP handover delay (BWP handover delay), the set of minimum values being valid in the new BWP. Otherwise, the minimum is invalid in the new BWP, and if the new BWP is configured with a default set of minimum values for each parameter, the set of minimum values in the new BWP is equal to the default set of minimum values, otherwise, the set of minimum values may be 0.

Alternatively, when a BWP handover occurs (e.g., BWP0 switches to BWP 1), if the DCI indicates BWP handover and no new minimum or indicated set of minimum values apply in the slot of the DCI triggering BWP handover with the minimum, if the acting delay is greater than the BWP handover delay (BWP handover delay), then in the new BWP the minimum may be determined to be one of:

(1) If a default set of minimum values is configured on the new BWP, the default set of minimum values may be applied before the set of minimum values indicated by the DCI take effect. Otherwise, the set of minimum values indicated by the DCI may be 0 before the set of minimum values take effect.

(2) The minimum value of each parameter may be 0 before the minimum value indicated by the DCI takes effect.

(3) The base station cannot schedule data on BWP until the minimum indicated by DCI takes effect.

(4) The minimum value indicated by the DCI may be invalid.

Alternatively, a minimum value of a set of parameters may be applied to the currently active BWP. When a BWP handover occurs, the minimum of all parameters may be invalid.

The default minimum value may be configured by RRC. Alternatively, the default minimum value may be a parameter configured on BWP. Alternatively, a default minimum value may not be configured.

Example embodiment 2

The base station may determine a set of minimum values according to the higher layer configuration signaling and/or the first preset information, and send the set of minimum values to the UE. The set of minimum values may be sent to the UE through L1 (layer 1) signaling (e.g., power save signaling).

The minimum value of the set of parameters may include at least one of: a minimum value of K0 (K0 min), a minimum value of K2 (K2 min), a minimum value of aperiodic SRS offset (SRSmin), a minimum value of slot offset between DCI triggering an aperiodic sounding reference signal and an associated aperiodic channel state information reference signal (offset-csi-min), a minimum value of K1 (K1 min).

Wherein the minimum value of all parameters may be greater than 0.

The base station and/or the terminal may determine an applicable (valid) range of the minimum value based on the determined minimum value and/or the second higher layer configuration information.

Optionally, the base station and/or the terminal may determine the invalid range of the minimum value based on the determined minimum value and/or the second higher layer configuration information.

Alternatively, the second higher layer configuration information may indicate a type of the downlink control information.

K1min may be used only for Downlink Control Information (DCI) with CS-RNTI scrambling and may indicate release of semi-persistent PDSCH (SPS PDSCH). In other words, the UE may not desire to receive DCI for the released SPS PDSCH including K1 less than K1 min. That is, if the UE receives PDCCH with an indication to release SPS PDSCH in slot n, it may transmit HARQ-ACK feedback after slot n + K1min or in slot n + K1 min.

Optionally, the second higher layer configuration information may indicate a type of DCI. If the DCI activates the SPS PDSCH, the set minimum may be invalid until the base station receives an ACK of the DCI releasing the SPS PDSCH. Alternatively, the nulling may start N slots after the DCI activating the SPS PDSCH, where N is the active delay.

Alternatively, the second higher layer configuration information may indicate a type of the downlink control information. K1min may be applied to DCI requiring HARQ feedback.

Optionally, the second higher layer configuration information indicates a type of downlink control information. K1min may apply to DCI with at least CS-RNTI scrambling, and may indicate release of semi-persistent PDSCH (SPS PDSCH).

Alternatively, the second higher layer configuration information may indicate a type of the downlink control information. K1min may only apply to DCI with CS-RNTI scrambling and may indicate release of semi-persistent PDSCH (SPS PDSCH).

Alternatively, K1min may be applied to DCI with at least C-RNTI or CS-RNTI or MCS-C-RNTI scrambling after receiving DCI activating SPS PDSCH and before receiving DCI releasing SPS PDSCH.

Alternatively, K1min may be applied to DCI with at least C-RNTI or CS-RNTI or MCS-C-RNTI scrambling. Alternatively, K1min may be applied at least to DCI scrambled with C-RNTI or CS-RNTI or MCS-C-RNTI and configured with a UE-specific search space (UESS).

Alternatively, K1min may be related to K0min (e.g., K1min = K0 min). Alternatively, k1min may be implicitly indicated by k0min, and the base station may not transmit k1min to the UE, and the k1min value may be indicated by k0min. Alternatively, K1min may be related to K2 min. Alternatively, K1min may be implicitly indicated by K2min, and the base station may not transmit K1min to the UE, and the K1min value may be indicated by K2 min.

Example embodiment 3

The minimum value of the set of parameters may include at least one of: a minimum value of K0 (K0 min), a minimum value of K2 (K2 min), a minimum value of aperiodic SRS offset (SRSmin), a minimum value of slot offset between DCI triggering aperiodic sounding reference signal and associated aperiodic channel state information reference signal (offset-csi-min), a minimum value of K1 (K1 min).

The base station/terminal may determine an applicable (valid) range for the minimum value based on the determined minimum value and/or the second higher layer configuration information.

The second higher layer configuration information comprises at least one of: (1) search space, (2) RNTI, (3) PDSCH-timedomainnalockationlist (PDSCH-TDRA), (4) PUSCH-timedomainnalockationlist (PUSCH-TDRA), (5) time domain resource, (6) frequency domain resource, and (7) type of downlink control information.

Alternatively, the second higher layer configuration information may be PDSCH-TDRA, and an applicable (effective)/valid (valid) range of the minimum value may be determined according to the minimum value indicated by the signaling and the second higher layer configuration information. The minimum value may be inactive (NA/inactive) if the high level does not configure the pdsch-TDRA or the number of k0 s in the high level configured pdsch-TDRA that are greater than or equal to k0min is less than or equal to Thred3, where Thred3 may be an integer greater than or equal to 0 and less than or equal to 8. Otherwise, the minimum value may be valid.

Alternatively, the second higher layer configuration information may be PUSCH-TDRA, and an applicable (effective)/valid (valid) range of the minimum value may be determined according to the minimum value indicated by the signaling and the second higher layer configuration information. The minimum value may be not functional (NA/invalid) if the high level has no pusch-TDRA configured or the number of k2 s greater than or equal to k2min in the high level configured pusch-TDRA is less than or equal to Thred4, where Thred4 may be an integer greater than or equal to 0 and less than or equal to 8. Otherwise, the minimum value may be valid.

Alternatively, the second higher-level configuration information may be a search space type. This set of minimum values may not be applicable to slots where the upper (higher) layer is configured with a common set of search spaces. The common search space set may be a Type0-PDCCH CSS (common search space) set, a Type0A-PDCCH CSS set, a Type1-PDCCH CSS set, a Type2-PDCCH CSS set, and/or a Type3-PDCCH CSS set.

Alternatively, the second higher-level configuration information may be a search space type. Alternatively, the set of minimum values may not be applicable to a common set of search spaces configured by higher layer signaling.

Alternatively, the second higher-level configuration information may be a search space type. Alternatively, the set of minimum values may apply only to the UE-specific search space. That is, the set of minimum values may only be valid in the UE-specific search space.

Alternatively, the second higher layer configuration information may be PDSCH-TDRA information. A set of minima may be invalid if the high (higher) layer is not configured with a pdsch-TDRA. Otherwise, the minimum value of the set of parameters may be valid.

Alternatively, the second higher-level configuration information may be a search space. When the configured common search space overlaps the UE-specific search space in time or frequency domain resources, the minimum of the set of parameters may be invalid for the overlap region.

Example embodiment 4

Fig. 1 shows a block diagram 100 of a minimum value for a set of parameters.

The base station may determine a set of minimum values according to the higher layer configuration signaling and/or the first preset information, and send the set of minimum values to the UE. The set of minimum values may be sent to the UE through L1 (layer 1) signaling (e.g., power save signaling). The minimum value of the set of parameters may include any one of: a minimum value of K0 (K0 min), a minimum value of K2 (K2 min), a minimum value of aperiodic SRS offset (SRSmin), a minimum value of slot offset between DCI triggering an aperiodic sounding reference signal and an associated aperiodic channel state information reference signal (offset-CSI-min), a minimum value of K1 (K1 min), a minimum value of slot offset between triggering downlink control information and an aperiodic non-zero power channel state information reference signal (NZP CSI-RS) resource group (a CSI-RSmin). Wherein the minimum value of all parameters may be greater than 0.

The UE may use the received minimum value to implement a set of parameters.

The UE may be configured with an aperiodic SRS (aperiodic sounding reference signal) associated with an aperiodic CSI-RS (aperiodic NZP CSI-RS resource), the associated CSI-RS being received an offset-CSI units after DCI triggering the aperiodic SRS. offset-CSI is a parameter configured by RRC and indicates an offset between DCI triggering aperiodic SRS and associated CSI-RS. Offset-csi may comprise a positive integer greater than or equal to 0, and the units of Offset-csi are slots or symbols or milliseconds.

The communication node may determine whether to receive the CSI-RS and whether to update the SRS precoding information based on the offset-CSI. The method may be one of the following:

alternatively, the UE may receive the CSI-RS if the offset-CSI value is greater than or equal to k0min or A CSI-RSmin and less than the A SRS offset; otherwise, the UE may not expect to receive the CSI-RS. Specifically, if the offset-CSI value is greater than or equal to k0min or a CSI-RSmin and the offset between the last symbol of the received CSI-RS and the first symbol of the transmitted SRS is greater than 42 symbols, the SRS precoding information may be updated. The a SRS offset is the offset that triggers multiple slots between the DCI and the actual transmission of this SRS-ResourceSet. A CSI-RSmin is the minimum value of slot offset between the trigger downlink control information and the aperiodic non-zero power channel state information reference signal (NZP CSI-RS) resource group.

Alternatively, the UE may receive the CSI-RS if the offset-CSI value is greater than or equal to a threshold offset-CSI-min and less than the A SRS offset, where offset-CSI-min is a positive integer greater than 0, otherwise the UE may not expect to receive the CSI-RS. The a SRS offset is the offset that triggers multiple slots between the DCI and the actual transmission of this SRS-ResourceSet.

Alternatively, offset-csi may be a parameter configured by the RRC in the SRS-Config information element. offset-csi may be a parameter in the aperiodic SRS-ResourceSet in the SRS-Config information element.

Alternatively, offset-CSI may be a parameter set configured by RRC, and the actual CSI-RS is received after N3 slots of receiving PDCCH (physical downlink control channel). Where N3 is the minimum value in the offset-csi list that is greater than offset-csi-min. If offset-csi-min is not present, N3 equals 0.

The offset-csi value is related to at least one of: an A SRS offset (e.g., offset-CSI = A SRS offset-X, where X is a positive integer greater than 0), K0min or A CSI-RSmin (e.g., offset-CSI is greater than or equal to K0min or A CSI-RSmin), K2min (e.g., offset-CSI = K2 min). In some embodiments, the offset-csi value is not configured, and if a minimum value greater than 0 is indicated to the UE, the default value may be 1; otherwise the default value may be 0.

Alternatively, the offset-CSI value may be related to k0min or a CSI-RSmin, if k0min or a CSI-RSmin is indicated to the UE, then offset-CSI = k0min or a CSI-RSmin; otherwise, the offset-csi value may be configured by RRC.

Alternatively, the offset-CSI value may be related to k0min or a CSI-RSmin, if k0min or a CSI-RSmin is indicated to the UE, then offset-CSI = k0min or a CSI-RSmin; otherwise it may be 0.

Alternatively, the minimum value of the set of parameters indicated by the base station may comprise offset-csi-min, which is the minimum value of offset-csi. Where offset-csi-min may be an integer greater than or equal to 0 and may be in units of slots or milliseconds or symbols. Alternatively, the minimum value of offset-csi may be indicated by power saving signaling. Alternatively, the minimum value of offset-csi (offset-csi-min) may be an implicit indication, i.e. offset-csi-min is not indicated in the power saving signaling and is the same as k0min (offset-csi-min = k0 min).

Alternatively, the minimum value of the minimum offset (offset-CSI-min) between the DCI triggering the aperiodic SRS and the associated aperiodic CSI-RS may be implicitly indicated by other minimum values. Where offset-csi-min may be an integer greater than or equal to 0 and may be in units of slots or milliseconds or symbols.

Optionally, the offset-CSI value that triggers the offset between the DCI of the aperiodic SRS and the associated aperiodic CSI-RS may be reinterpreted by the minimum value indicated by the signaling (e.g., offset-CSI = k0 min). The value of the parameter may be reset to equal the corresponding minimum value. Alternatively, the offset-CSI value that triggers the offset between the DCI for aperiodic SRS and the associated aperiodic CSI-RS may be configured by RRC, and if not present, the default value may be 0.

Example 5

The base station may determine a minimum value of a given set of parameters according to the first preset information and/or the high layer configuration signal, and may transmit the minimum value of the set of parameters determined by the base station to the UE. Wherein the minimum value of all parameters may be greater than 0.

The base station may determine an applicable (valid) range of the minimum value based on the determined minimum value and/or the second higher layer configuration information.

Optionally, the second higher layer configuration information may be: time domain resources A1 configured by a higher layer to transmit SRS or PUCCH or PUSCH or PRACH (physical random access channel), time domain resources A2 configured by a higher layer to receive CSI-RS or PDSCH, time domain resources B and frequency domain resources B configured for detection of SFI-RNTI, DCI format 0_0, DCI format 0_1, DCI format 1_0, DCI format 1_1 or DCI format 2_3, where time domain resources B precede time domain resources A1 or A2. And the slot offset between time domain resource B and time domain resource A1 or A2 is less than or equal to 32.

Optionally, the second higher layer configuration information is time domain resource A1 or A2, and if time domain resource A1 or A2 is configured, the minimum value of all parameters may not be applicable (not valid) in time domain resource B and frequency domain resource B.

Alternatively, the second higher layer configuration information is time domain resource A1 or A2, and if time domain resource A1 or A2 is configured, the minimum value of all parameters may not be applicable (not valid) in the time slot including time domain resource B and frequency domain resource B.

Optionally, the second higher layer configuration information is a time domain resource A1 or A2, and if the time domain resource A1 or A2 is configured, the minimum value of all the parameters may be an inapplicable (non-valid) minimum value in the search space where the time domain resource B and the frequency domain resource B are located.

Optionally, the second higher layer configuration information is a time domain resource A1 or A2, and if the time domain resource A1 or A2 is configured, the DCI decoding time is less than N slots, where N is an integer greater than or equal to 0.

Alternatively, the second higher layer configuration information is time domain resource A1 or A2, and if time domain resource A1 or A2 is configured to transmit or receive data, the minimum value of all parameters is not applicable (not valid) until the transmission is completed, and may be valid after the transmission is completed.

The UE may use the received minimum value to implement a set of parameters.

Alternatively, the UE may be configured by higher layers to transmit SRS, or PUCCH, or PUSCH, or PRACH, then the UE may not desire to cancel transmission in symbols from a subset of symbols that are less than T2 symbols after the last symbol of CORESET in which the UE detected DCI format 2_0, or DCI format 1_0, or DCI format 1_1, or DCI format 0_1. T2 may be greater than or equal to the PUSCH preparation time for the corresponding PUSCH processing capability. Alternatively, T2 may be associated with k0min. Alternatively, T2 may be associated with DCI decoding time. The UE may cancel PUCCH, or PUSCH, or PRACH transmissions in the remaining symbols from the set of symbols and cancel SRS transmissions in the remaining symbols from the subset of symbols.

Example 6

The base station may determine a minimum value of a given set of parameters according to the first preset information and/or the high layer configuration signal, and may transmit the minimum value of the set of parameters determined by the base station to the UE.

Wherein the minimum value of all parameters may be greater than 0.

The UE may support cross-carrier scheduling, the minimum of the set of parameters being the configuration on the scheduled component carrier (scheduling CC).

Fig. 2 shows a block diagram 200 of various scheduled carriers.

Alternatively, the minimum value on other scheduled component carriers (scheduled CCs) that the scheduling component carrier can schedule is implicitly indicated by the minimum value indicated on the scheduling component carrier. The UE may not expect to receive scheduling requests less than the minimum value. The implicit indication may be that a set of minimum values on the scheduled component carrier is determined based on a set of minimum values configured on the scheduling component carrier. The minimum value (k 0min/k2min/k1 min/SRSmin/offset-csi-min) of the set of parameters may indicate the scheduling component carrier CC (a) configuration, and then the minimum value (k 0min (I)/k 2min (I)/k 1min (I)/SRSmin (I)/offset-csi-min (I)) on the other scheduled component carriers CC (I) is determined by converting the minimum value set on the scheduling component carrier by Kmin (I) = Operation (Kmin, M), where Kmin may be one of: k0min, k2min, k1min, SRSmin, offset-csi-min, M may be a real number, and the operation may be a multiplication operation or an addition operation (e.g., kmin (I) = Kmin × M, kmin (I) = Kmin + M).

Alternatively, M may be related to SCS of the component carriers (e.g.,

)。

alternatively, the minimum value (k 0min/k2min/k1min/SRS min/offset-CSI-min) may be indicated as a configuration on a certain scheduled component carrier, and the minimum value is larger than 0. If the DCI indicates cross-carrier scheduling, the UE may not expect to receive the PDSCH on the scheduled component carrier within a time corresponding to k0min after receiving the PDCCH (calculated with SCS scheduling the component carrier). If the DCI indicates cross-carrier scheduling, the UE may not expect to transmit PUSCH on the scheduled component carrier at a time corresponding to k2min after receiving the PDCCH (in SCS computation of the scheduling carrier unit). If the DCI indicates cross-carrier scheduling, the UE may not expect to transmit or receive data within a time (in SCS computation of the scheduling component carrier) corresponding to k0min after receiving the PDCCH.

The UE may use the received minimum value to implement a set of parameters.

Alternatively, if the indicated minimum value of the set of parameters is greater than 0, the timeDurationForQCL may be converted. For example: the timeDurationForQCL may be associated with k0min, timeDurationForQCL = timeDurationForQCL + k0min N, where N is a positive integer greater than 0. The timeDurationForQCL may not change if the minimum value of a set of parameters is equal to 0 or does not indicate a minimum value. In this embodiment, N equals 14.

Alternatively, if the indicated minimum value of the set of parameters is greater than 0 and the decoded DCI Time1 reported by the UE is greater than 1 slot, the timeduration formqcl may be converted. For example: timeDurationForQCL = timeDurationForQCL + Time1 × N, where N is a positive integer greater than 0. Where the unit of Time1 is a Time slot. Otherwise, the timeDurationForQCL may not change. In this embodiment, N equals 14.

Optionally, the timeduration formqc may be associated with k2min (e.g., timeduration formqc = k2 min) if the indicated minimum value of the set of parameters is greater than 0. Optionally, the timeDurationForQCL may be associated with the DCI decoding time. Alternatively, the timeduration form qcl may be converted by timeduration form qcl = timeduration form qcl + T1, where T1 may be an integer greater than 0.

The minimum value of the set of parameters may be greater than 0.

The bwswitchingdelay may be a BWP switching delay (BWP switching delay), and the deta1 may be an integer greater than or equal to 0. Alternatively, deta1= k0min.

Alternatively, if the base station desires to indicate the DCI triggered BWP handover, and the indicated k0min >0 or k0min is greater than the BWP handover delay, the base station may first re-indicate a set of minimum values by using power saving signaling, where at least k0min is included in the set of minimum values. k0min may be less than or equal to the BWP handoff delay. And then transmits a DCI signal triggering BWP switching,

alternatively, if the base station desires to indicate BWP handover triggered by DCI and the decoded DCI time reported by the UE is greater than or equal to the BWP handover delay, the base station may first re-indicate a set of minimum values by using power saving signaling before transmitting the DCI triggering BWP handover, where the set of minimum values may be equal to 0. And then transmits a DCI signal triggering BWP switching.

Accordingly, the techniques of this disclosure are not limited, except as by the appended claims.

The disclosed and other embodiments, modules, and functional operations described in this document can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this document and their structural equivalents, or in combinations of one or more of them. The disclosed and other embodiments may be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer-readable medium for execution by, or to control the operation of, data processing apparatus. The computer readable medium can be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter effecting a machine-readable propagated signal, or a combination of one or more of them. The term "data processing apparatus" encompasses all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. The apparatus can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them. The propagated signal is an artificially generated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus.

A computer program (also known as a program, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store portions of one or more modules, sub programs, or code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described herein can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit).

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. However, a computer does not require such a device. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices (e.g., EPROM, EEPROM, and flash memory devices); magnetic disks (e.g., internal hard disks or removable disks); magneto-optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
