Fig. 2 is an interactive schematic diagram illustrating a communication processing method according to an embodiment of the present disclosure. As shown in fig. 2, an embodiment of the present disclosure relates to a communication processing method, including:

in step S2101, the network apparatus 102 transmits a first RS to the terminal 101.

In some embodiments, the first RS is used for activation of the first TCI state.

In some embodiments, the network device 102 may include one or more multi-transmission reception points (multiple transmission reception point, mTRP).

Alternatively, the first TCI state may represent one of the TCI states of a certain TRP, or represent the TCI state of a certain TRP of a plurality of TRPs.

Alternatively, when the network device 102 includes one TRP, the first RS may be transmitted by the TRP.

Optionally, when the network device 102 includes a plurality of TRPs, the first RS is transmitted by the TRP corresponding to the first TCI state. For example, the first RS is used for activation of a first TCI state of a first TRP (TRP 1), the first RS being transmitted by TRP 1.

In some embodiments, when the network device 102 includes one TRP, the first RS is an RS for TRP Downlink (DL) TCI state activation.

Optionally, the first TCI state is a DL TCI state.

Alternatively, during the DL TCI state activation, the terminal 101 may perform different operations according to different situations of the DL TCI state.

In an example, when the DL TCI state is known (known) or is a known TCI state, the terminal 101 needs to perform time-frequency synchronization or time-frequency tracking (T/F tracking) during the activation of the DL TCI state.

In another example, when the DL TCI state is unknown or unknown, during activation of the DL TCI state, the terminal 101 needs to perform beam measurement, beam scanning or layer-one reference signal received power (layer reference signal received power, L1-RSRP) measurement to obtain L1-RSRP.

Optionally, the RS for DL TCI state activation includes one of:

RS for beam measurement, wherein DL TCI state is an unknown TCI state.

Optionally, RS is one of: a synchronization signal block (synchronization signal/physical broadcast channel block, SSB); channel-state-information reference signal (CSI-RS).

For example, the first RS is an SSB or CSI-RS for time frequency tracking; alternatively, the first RS is an SSB or CSI-RS for beam measurement.

In some embodiments, when the network device includes a plurality of TRPs, the first RS is transmitted by a first TRP of the plurality of TRPs.

Optionally, the first RS is used for activation of a TCI state of a first TRP (TRP 1) and is transmitted by the first TRP.

Alternatively, the TCI state of the first TRP may be known or unknown. The TCI state may also be a DL TCI state or an Uplink (UL) TCI state.

Optionally, the first RS is one of:

a DL TCI state activated RS for the first TRP;

UL TCI state activated RS for the first TRP.

For example, when the first RS is activated for the DL TCI state of the first TRP, if the DL TCI state is known, the first RS may be SSB or CSI-RS for time frequency synchronization; if the DL TCI state is unknown, the first RS may be an SSB or CSI-RS for beam measurement.

Optionally, in UL TCI state activation, uplink signal transmission requires additional path loss computation when a path loss reference signal (PL-RS) is not maintained. If the UL TCI state is known, during the activation of the UL TCI state of the first TRP, the terminal 101 needs to perform uplink path loss measurement, such as measuring the PL-RS sent by the first TRP. If the UL TCI state is unknown, the terminal 101 needs to perform uplink path loss measurement and beam measurement during the activation of the UL TCI state of the first TRP.

Optionally, the RS for UL TCI state activation includes one of:

For example, when the first RS is activated for the UL TCI state of the first TRP, if the UL TCI state is known, the first RS may be SSB or CSI-RS for uplink path loss measurement; if the UL TCI state is unknown, the first RS may include SSB or CSI-RS for uplink path loss measurement and SSB or CSI-RS for beam measurement.

In step S2102, the network device 102 transmits the second RS to the terminal 101.

In some embodiments, the second RS is used for activation of the second TCI state.

Alternatively, the second TCI state may represent one of the TCI states of a certain TRP, the same as or different from the first TCI state; or a TCI state representing a TRP among the plurality of TRPs, different from the TRP corresponding to the first TCI.

Alternatively, when the network device 102 includes one TRP, the second RS may be transmitted by the TRP.

Optionally, when the network device 102 includes a plurality of TRPs, the second RS is transmitted by the TRP corresponding to the second TCI state. For example, the second RS is used for activation of a second TCI state of a second TRP (TRP 2), the second RS being transmitted by TRP 2.

In some embodiments, when the network device 102 includes one TRP, the second RS is an RS for TRP UL TCI state activation.

Optionally, the second TCI state is a UL TCI state.

Alternatively, the operation of the terminal 101 in the UL TCI state activation procedure may be described with reference to step S2101, which is not described herein.

Optionally, the RS for UL TCI state activation includes one of:

For example, the second RS is an SSB or CSI-RS for uplink path loss measurement, or the second RS is an SSB or CSI-RS for uplink path loss measurement and beam measurement.

In some embodiments, when the network device includes a plurality of TRPs, the second RS is transmitted by a second TRP of the plurality of TRPs.

Optionally, the second RS is used for TCI state activation of and transmitted by a second TRP (TRP 2).

Alternatively, the TCI state of the second TRP may be known or unknown, and the TCI state may also be a DL TCI state or a UL TCI state.

Optionally, the second RS is one of:

a DL TCI state activated RS for the second TRP;

UL TCI state activated RS for the second TRP.

Alternatively, the second RS may be used for time-frequency synchronization or beam measurement when the second RS is used for DL TCI state activation of the second TRP.

For example, when the second RS is activated for the DL TCI state of the second TRP, if the DL TCI state is known, the second RS may be SSB or CSI-RS for time frequency synchronization; if the DL TCI state is unknown, the second RS may be an SSB or CSI-RS for beam measurement.

Optionally, the second RS may be used for uplink path loss measurement and/or beam measurement when the second RS is used for UL TCI state activation of the second TRP.

For example, when the second RS is activated for the UL TCI state of the second TRP, if the UL TCI state is known, the second RS may be SSB or CSI-RS for uplink path loss measurement; if the UL TCI state is unknown, the second RS may include SSB or CSI-RS for uplink path loss measurement and SSB or CSI-RS for beam measurement.

In step S2103, the terminal 101 receives and measures the first RS and/or the second RS in the conflicting time domain interval.

In some embodiments, there may be a time domain collision between the first RS and the second RS sent by the network device 102, for example, the transmission periods of the first RS and the second RS are the same, or the transmission periods and the start offsets of the first RS and the second RS are the same.

Alternatively, the time domain collision or collision may be that the first RS overlaps or is adjacent to the time domain unit where the second RS is located.

In a first example, in conjunction with the descriptions of steps S2101 and S2102, when the network device 102 includes one TRP, the existence of a time domain collision between the first RS and the second RS may be: the DL TCI state activated RS for the TRP collides with the UL TCI state activated RS for the TRP, for example, the SSB for T/F tracking or beam measurement of the TRP collides with the RS for path loss measurement in the time domain.

In a second example, in conjunction with the descriptions of steps S2101 and S2102, when the network device 102 includes a plurality of TRPs, the existence of a time domain collision between the first RS and the second RS may be one of:

an RS for UL TCI state activation of TRP1 collides with an RS for UL TCI state activation of TRP2, for example, two TRP-transmitted PL-RSs collide in time domain;

the DL TCI state activated RS for TRP1 collides with the UL TCI state activated RS for the second TRP, for example, SSB for T/F tracking or beam measurement of TRP1 may collide with PL-RS for path loss calculation of TRP 2;

the RS for DL TCI state activation of TRP1 collides with the RS for DL TCI state activation of the second TRP, for example, SSB for T/F tracking or beam measurement of TRP1 may collide with SSB for T/F tracking or beam measurement of TRP 2.

In some embodiments, when the above-described possible collision occurs, the terminal 101 may measure one of the first RS and the second RS and not receive or listen to the other of the first RS and the second RS.

Alternatively, the terminal 101 may not receive or listen to one of the RSs, may discard the RS, may not expect the network device 102 to transmit the RS, or may consider the network device 102 not to transmit the RS.

In the first example described above, when there is a time domain collision between the first RS and the second RS, the terminal 101 may discard one of them. For example, SSBs for T/F tracking or beam measurement of TRP collide with RSs for path loss measurement in the time domain, and the terminal 101 discards SSBs for T/F tracking or beam measurement or RSs for path loss measurement.

In the second example described above, when there is a time domain collision between the first RS and the second RS, the terminal 101 may discard one of them.

For example, the time domain collision of the PL-RSs transmitted by two TRPs occurs, and the terminal 101 discards the PL-RS of TRP1 or the PL-RS of TRP 2;

for another example, SSB for T/F tracking or beam measurement of TRP1 may collide with PL-RS for path loss calculation of TRP2, and terminal 101 discards SSB for T/F tracking or beam measurement of TRP1 or PL-RS of TRP 2;

For another example, SSB for T/F tracking or beam measurement of TRP1 may collide with SSB for T/F tracking or beam measurement of TRP2, and terminal 101 discards SSB for T/F tracking or beam measurement of TRP1 or SSB for T/F tracking or beam measurement of TRP 2.

In this embodiment, the terminal 101 cannot complete activation of the first TCI state and the second TCI state at the same time.

In some embodiments, the terminal 101 receives and measures the first RS and the second RS when the above-described possible collision occurs.

Alternatively, when the communication band is in the Frequency Range (FR) 1, the terminal 101 may receive the first RS and the second RS simultaneously.

Optionally, when the communication band is FR2, the terminal 101 may extend the activation delay by measuring the first RS and the second RS.

In some embodiments, when the terminal receives and measures the first RS and the second RS, the total delay for the terminal 101 to complete the first TCI state activation and the second TCI state activation is greater than the activation delay time for the first TCI state or the second TCI state is defined.

Alternatively, in the time domain interval of the collision, the terminal 101 may alternately receive the first RS and the second RS, e.g. receive and measure the first RS in the first time domain unit of the collision and receive and measure the second RS in the second time domain unit of the collision.

Alternatively, the determination or calculation of the activation delay time of the TCI state may be defined by a protocol.

Alternatively, the network device 102 may indicate the TCI state of the present activation by sending an activation command to the terminal 101. Wherein the TCI state indicating activation in the activate command may be referred to as a target TCI state or a new TCI state.

Optionally, the activation delay time may include: the terminal 101 receives the activation command until the period of completing the TCI state activation indicated by the activation command, and after completing the TCI state activation, the terminal 101 may consider that the TCI state switching is completed, i.e. the target TCI state may be applied.

Alternatively, the activation command may employ a medium access control layer control unit (Media Access Control Control Element, MAC CE). For example, when the network device includes one TRP, the network device may be activated by one MAC CE configuration to activate the first TCI state and the second TCI state of the TRP.

Optionally, the activation delay time determination parameters are different depending on whether the first TCI state or the second TCI state is known or unknown. For example, for DL TCI state, when DL TCI state is not in the active TCI state list of PDSCH, the terminal 101 needs an additional SSB to acquire the time/frequency of target TCI state. If the DL TCI state is unknown, the terminal 101 needs to perform additional Receive (RX) beam scans or L1-RSRP measurements based on multiple SSBs or CSI-RSs. For another example, for UL TCI state, when PL-RS of uplink transmission is not maintained, the terminal 101 needs to calculate path loss during UL TCI state activation.

Thus, in connection with the different cases of the first TCI state and the second TCI state, the corresponding activation delay time may be determined by reference to one of the following examples:

in a first example, if the TCI state is a known DL TCI state, the corresponding activation delay time for the TCI state is:

slot length (slot length);

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, T _first-SSB Representing the duration between the reception of the first downlink RS of the MAC CE to TRP transmission, T _SSB-proc For the downlink RS processing time,and TO _k Is constant.

It is noted that SSBs in the formula are sent by the TRP corresponding to the TCI state. For example, if the activation delay time of the TCI state of TRP1 is to be determined, the SSB is transmitted by TRP1 in the formula.

In a second example, if the TCI state is an unknown DL TCI state, the corresponding activation delay time for the TCI state is:

the time slot length;

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, TL1-RSRP representing the time of L1-RSRP measurement in the beam measurement, T _first-SSB Representing the duration between the reception of the first downlink RS of the MAC CE to TRP transmission, T _SSB-proc For the downlink RS processing time, And TOu _k Is constant.

In a third example, if the TCI state is a known UL TCI state, the corresponding activation delay time for the TCI state is:

the time slot length;

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, T _{first-target-PL-Rs} Representing the time period from decoding the MAC CE to the first PL-RS for uplink loss measurement, T _target-PL-Rs The period of the downlink PL-RS is shown,is constant with NM.

In a fourth example, if the TCI state is an unknown UL TCI state, the corresponding activation delay time for the TCI state is:

the time slot length;

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, T _{first-tatget-PL-RS} Representing the time period from decoding the MAC CE to the first PL-RS for uplink loss measurement, T _target-PL-Rs Represents the period of the downlink PL-RS, T _L1-RsRP Representing the time of the L1-RSRP measurement in the beam measurement,is constant. />

Optionally, when the terminal 101 measures the first RS and the second RS, the delay for activating the first TCI state and the second TCI state will be prolonged, such as greater than the activation delay for the first TCI state or greater than the activation delay for the second TCI state determined according to the above example.

In step S2104, the network apparatus 102 does not transmit scheduling data to the terminal 101 during a period in which the first RS and/or the second RS transmit.

Alternatively, the terminal 101 does not listen to the scheduling data during the period in which the first RS and/or the second RS transmit.

For example, during the period in which the first RS transmission is located, the terminal 101 does not monitor the scheduling data, or does not expect the network device 102 to send the scheduling data, so as not to affect the activation procedure of the first TCI state; for another example, during the period in which the second RS transmission is located, the terminal 101 does not monitor the scheduling data, or does not expect the network device 102 to send the scheduling data, so as not to affect the activation procedure of the second TCI state; for another example, the terminal 101 does not listen to the scheduling data or expect the network device 102 to send the scheduling data during the period in which the first RS transmission is located and the period in which the second RS transmission is located, so as not to affect the activation procedure of the two TCI states.

Optionally, the scheduling data comprises, for example, a physical downlink shared channel (physical downlink shared channel, PDSCH) or a physical downlink control channel (physical downlink control channel, PDCCH).

Alternatively, this step may be applicable to scheduling constraints in multiple TRP scenarios.

For example, during TCI state activation of two TRPs, the terminal 101 cannot be scheduled data while the terminal 101 is performing RS measurements for T/F tracking or PL-RS. When the terminal 101 supports a round-trip-delay (RTD) > measurement capability of Cyclic Prefix (CP), the timing offset between two TRPs may be larger than the CP, and there may be a plurality of time domain units having a scheduling restriction.

In some embodiments, the time period comprises one of:

a time domain unit in which the first RS or the second RS is transmitted, wherein a time difference between the first RS and the second RS is less than or equal to a CP;

Optionally, the time difference is used to indicate a difference between the first RS being transmitted by the first TRP and the second RS being transmitted by the second TRP, or a timing offset. The time difference may also be denoted RTD.

Alternatively, the time domain units may be time slots, symbols, milliseconds, etc.

In an example, taking a time domain unit as an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol as an example, the terminal 101 does not expect to transmit an uplink channel or signal on a portion of the OFDM symbol, such as transmitting a physical uplink shared channel (physical uplink shared channel, PUSCH), a physical uplink control channel (physical uplink control channel, PUCCH), or a channel sounding reference signal (sounding reference signal, SRS), or the terminal 101 does not expect to receive an PDCCH, PDSCH, CSI-RS for tracking or a CSI-RS for channel quality indication CQI on a portion of the OFDM symbol.

In this example, the partial OFDM symbol is:

if the terminal 101 supports RTD > CP measurement capability, the partial OFDM symbol includes: an OFDM symbol where an SSB for T/F tracking or a PL-RS for path loss calculation is located, and 1 OFDM symbol before or after the OFDM symbol;

if the terminal 101 does not support the measurement capability of RTD > CP, the partial OFDM symbol is an SSB for T/F tracking or an OFDM symbol where PL-RS for path loss calculation is located.

in some embodiments, reference may be made to other alternative implementations described before or after the description corresponding to fig. 4 b.

In the method of the present disclosure, the behavior of the UE is defined in a scenario where an RS for DL TCI state activation of one TRP overlaps or is adjacent to an RS for UL TCI state activation of the TRP, or an RS for TCI state activation of one TRP overlaps or is adjacent to an RS for TCI state activation of another TRP, respectively. To facilitate an understanding of the disclosed embodiments, a few examples are set forth below.

In one aspect, in a single TRP (single TRP) scenario, a network device (NW) may configure one DL TCI state active and one UL TCI state active in one MAC CE. See examples one through four below.

Example one:

based on the current TCI state activation delay (activation delay) requirement, for a known DL TCI state, the UE needs an additional SSB to acquire the time or frequency (time/frequency) of the target TCI state when the DL TCI state is not in the activated TCI state list (active TCI state list) of the PDSCH. For unknown DL TCI states, the UE needs to perform additional RX beam scans (e.g., L1-RSRP measurements) based on multiple SSBs or CSI-RSs. The requirements for the associated activation delay time are as follows:

For a known DL TCI state, the activation delay time is:

slot length (slot length);

Alternatively, the above-mentioned time may be a slot (slot).

Optionally, if the target TCI state is not on the active TCI state list corresponding TO the downlink channel, TO _k =1, otherwise, TO _k ＝0。

Alternatively T _SSB-proc ＝2ms。

Optionally, the activation delay is used to indicate the duration for the UE to complete TCI state activation, or the duration required for TCI state switching (from old TCI state to target TCI state).

For an unknown DL TCI state, the activation delay time is:

the time slot length;

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, T _L1-RSRP Representing the time of L1-RSRP measurement in beam measurement, T _first-SSB Representing the duration between the reception of the first downlink RS of the MAC CE to TRP transmission, T _SSB-proc For the downlink RS processing time,and TOu _k Is constant.

Example two:

for the UL TCI state, when a path loss reference signal (PL-RS) for uplink transmission is not maintained, the UE needs to calculate the path loss during UL TCI state activation. The requirements for the associated activation delay time are as follows:

For a known UL TCI state, the activation delay time is:

the time slot length;

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, T _{first-target-PL-RS} Representing the time period from decoding the MAC CE to the first PL-RS for uplink loss measurement, T _target-PL-Rt The period of the downlink PL-RS is shown,is constant with NM.

For an unknown UL TCI state, the receive beam requires additional L1-RSRP measurements with an activation delay of:

the time slot length;

wherein n represents time of receiving MAC CE, T _HARQ Representing the time between the MAC CE and the corresponding acknowledgement feedback information, T _{first-target-PL-RS} Representing the time period from decoding the MAC CE to the first PL-RS for uplink loss measurement, T _target-PL-RS Represents the period of the downlink PL-RS, T _L1-RSRP Representing the time of the L1-RSRP measurement in the beam measurement,is constant.

Example three:

with the example one and the example two, for one TRP, the RS for its DL TCI state activation overlaps or is adjacent to the RS for its UL TCI state activation in the time domain, and the UE may need to discard one of the RSs. If the UE still needs to measure two RSs, the total TCI activation delay time will be extended.

Optionally, the activation procedure of the DL TCI state may include: the UE performs Time-frequency synchronization or Time-frequency tracking (Time/Frequency tracking), or beam measurement to obtain L1-RSRP. Wherein, the RS for DL TCI state activation may be an RS for time-frequency tracking or L1-RSRP measurement.

Wherein it is also possible that the RS for time-frequency tracking or L1-RSRP overlaps or is adjacent to the RS for L1-RSRP measurement.

Optionally, the activation procedure of the UL TCI state may include: the UE performs PL-RS measurements or the UE performs PL-RS and beam measurements.

When a time domain collision occurs, the UE behavior may include the following several possibilities:

(1) The UE discards the RS (e.g., SSB) for T/F tracking;

(2) The UE discards the RS (e.g., SSB or CSI-RS) for L1-RSRP measurement;

(3) The UE discards the PL-RS (such as SSB or CSI-RS) used for path loss calculation;

(4) If the UE is to measure two RSs, the total activation time will be extended;

wherein, for (1) - (3), the UE cannot complete TCI activation for both TCI states at the same time.

Example four:

based on example three, the applicability of TCI state activation is defined, which depends on whether the TCI state corresponds to frequency range FR1 or FR2.

For FR1, when two RSs overlap or are adjacent, the UE can measure both RSs simultaneously, without measurement restriction.

For FR2, when SSB for T/F tracking overlaps or is adjacent to SSB for PL-RS measurement, UE needs to measure one RS instead of two RSs; or there may be a longer activation delay or no other definition, or

When SSBs for T/F tracking overlap or are adjacent to RSs for L1-RSRP measurement, the UE needs to measure one of the RSs instead of two RSs; or there may be a longer activation delay or no other definition, or

When the RS for L1-RSRP measurement overlaps or is adjacent to the PL-RS, the UE needs to measure one of the RSs instead of both RSs; alternatively, there may be a longer activation delay or no other definition.

On the other hand, in a multi-TRP (mTRP) scenario, it is assumed that there are two TRPs, TRP1 and TRP2, respectively. The NW will configure TCI state activation for two TRPs of the following three scenarios:

(1) DL TCI status (DL-only) activation of TRP1 and UL TCI status activation (UL-only) of TRP 2;

(2) UL TCI status (UL-only) activation of TRP1 and UL TCI status activation (UL-only) of TRP 2;

(3) DL TCI state activation and UL TCI state (DL and UL TCI state) activation of TRP1, and DL TCI state activation and UL TCI state activation of TRP2.

Time domain collisions that may exist in three scenarios may be referenced by examples five through ten below.

Example five:

depending on whether the TCI state is known, or whether T/F tracking is required, or whether path loss computation is required, the time domain collision in scenario (1) above may include the following:

the SSB of TRP1 for T/F tracking has time domain conflict with PL-RS of TRP 2;

there is a time domain collision of TRP1 for T/F tracking SSB with TRP2 for RS for L1-RSRP measurement.

Example six:

depending on whether the TCI state is known, or whether T/F tracking is required, or whether path loss computation is required, the time domain collision in scenario (2) above may include the following:

The RS for L1-RSRP measurement of TRP1 has time domain collision with the PL-RS of TRP 2;

there is a time domain collision between the PL-RS of TRP1 and the PL-RS of TRP 2.

Example seven:

depending on whether the TCI state is known, or whether T/F tracking is required, or whether path loss computation is required, the time domain collision in scenario (3) above may include the following:

the SSB of TRP1 for T/F tracking has time domain conflict with PL-RS of TRP 2;

Example eight:

in combination with examples five to seven, due to UE capability limitations, in these collision cases, the UE may need to discard some conflicting RSs, as with reference to the following alternatives:

alternative 1: the UE discards the RS of TRP1, including the RS for T/F tracking, L1-RSRP measurement or path loss calculation;

alternative 2: the UE discards the RS of TRP2, including the RS for T/F tracking, L1-RSRP measurement or path loss calculation;

alternative 3: if the UE can measure two or more RSs, the total activation delay time will be extended.

Alternative 1 and alternative 2 described above, the ue cannot complete TCI state activation of two TRPs at the same time.

Example nine:

Based on example eight, define applicability of TCI state activation:

when SSBs for T/F tracking overlap or are adjacent to PL-RSs of two TRPs, the UE needs to measure one of the RSs instead of two RSs; or there may be a longer activation delay or no other definition, or

When SSBs for T/F tracking of two TRPs overlap or are adjacent to RSs for L1-RSRP measurement, the UE needs to measure RSs of one TRP instead of RSs of two TRPs; or there may be a longer activation delay or no other definition, or

When the RS for L1-RSRP measurement and the PL-RS of two TRPs overlap or are adjacent, the UE needs to measure the RS of one TRP instead of the RS of two TRPs; or there may be a longer activation delay or no other definition, or

When PL-RSs of two TRPs overlap or are adjacent, the UE needs to measure one of the RSs instead of both RSs; or there may be a longer activation delay or no other definition, or

When PL-RS of one TRP overlaps with RSs for L1-RSRP measurement, PL-RS of another TRP, RSs for beam failure detection (beam failure detection, BFD) or candidate beam detection (candidate beam detection, CBD), RSs for radio link monitoring (radio link monitoring, RLM), the UE needs to measure RSs of one TRP instead of RSs of two TRP. Alternatively, there may be a longer activation delay or no other definition.

Example ten:

based on the above example, there is a scheduling restriction in the mTRP scenario (scheduling restriction).

During the TCI state activation of two TRPs, the UE cannot be scheduled with data when the UE is performing measurements on the RS for T/F tracking or PL-RS. When the UE supports the measurement capability of RTD > CP, the timing offset between two TRPs may be larger than CP, and then one additional symbol needs to be considered in defining the scheduling constraint.

For example, the scheduling constraints include:

before the UE completes two TCI state activations, it is not expected that the UE transmits PUCCH, PUSCH or SRS on the relevant OFDM symbol, or it is not expected that the UE receives PDCCH, PDSCH, CSI-RS for tracking or CSI-RS for CQI on the relevant OFDM symbol, where the relevant OFDM symbol is:

SSB for T/F tracking or OFDM symbol of PL-RS for path loss calculation, and 1 OFDM symbol before or after, wherein UE supports RTD > CP;

SSB for T/F tracking, SSB for L1-RSRP measurement, or OFDM symbols for PL-RS for path loss calculation, wherein the UE does not support RTD > CP.
