[0156] In an embodiment of the present disclosure, during activation of a unified TCI state, since a network (NW) such as network device 102 can be configured to activate different TCI states, a reference signal (RS) used in activation processes of different TCI states may conflict in the time domain, and it is necessary to define terminal behavior under different conflict scenarios.
[0157] FIG2 is an interactive diagram of a communication processing method according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a communication processing method, the method comprising:
[0158] Step S2101 : The network device 102 sends a first RS to the terminal 101 .
[0159] In some embodiments, the first RS is used for activation of the first TCI state.
[0160] In some embodiments, the network device 102 may include one or more multiple transmission reception points (mTRPs).
[0161] Optionally, the first TCI state may represent one of the TCI states of a certain TRP, or represent the TCI state of a certain TRP among multiple TRPs.
[0162] Optionally, when the network device 102 includes a TRP, the first RS can be sent by the TRP.
[0163] Optionally, when the network device 102 includes multiple TRPs, the first RS is sent by the TRP corresponding to the first TCI state. For example, the first RS is used to activate the first TCI state of the first TRP (TRP1), and the first RS is sent by TRP1.
[0164] In some embodiments, when the network device 102 includes a TRP, the first RS is an RS for activating the TRP downlink (DL) TCI state.
[0165] Optionally, the first TCI state is a DL TCI state.
[0166] Optionally, during the process of activating the DL TCI state, the terminal 101 may perform different operations according to different situations of the DL TCI state.
[0167] In one example, when the DL TCI state is known or a known TCI state, during the activation of the DL TCI state, the terminal 101 needs to perform time-frequency synchronization or time-frequency tracking (T / F tracking).
[0168] In another example, when the DL TCI state is unknown or an unknown TCI state, during the activation process of the DL TCI state, the terminal 101 needs to perform beam measurement, beam scanning or layer reference signal received power (L1-RSRP) measurement to obtain L1-RSRP.
[0169] Optionally, the RS used for DL TCI state activation includes one of the following:
[0170] RS for time-frequency synchronization, where the DL TCI state is a known TCI state;
[0171] RS used for beam measurement, where the DL TCI state is unknown TCI state.
[0172] Optionally, the RS is one of the following: a synchronization signal / physical broadcast channel block (SSB); a channel-state-information reference signal (CSI-RS).
[0173] For example, the first RS is an SSB or CSI-RS used for time-frequency tracking; or, the first RS is an SSB or CSI-RS used for beam measurement.
[0174] In some embodiments, when the network device includes multiple TRPs, the first RS is transmitted by the first TRP among the multiple TRPs.
[0175] Optionally, the first RS is used for activation of the TCI state of the first TRP (TRP1) and is sent by the first TRP.
[0176] Optionally, the TCI state of the first TRP may be known or unknown, wherein the TCI state may also be a DL TCI state or an uplink (UL) TCI state.
[0177] Optionally, the first RS is one of the following:
[0178] RS with DL TCI state activated for the first TRP;
[0179] RS with UL TCI state activated for the first TRP.
[0180] For example, when the DL TCI state of the first RS for the first TRP is activated, if the DL TCI state is known, the first RS can be an SSB or CSI-RS for time-frequency synchronization; if the DL TCI state is unknown, the first RS can be an SSB or CSI-RS for beam measurement.
[0181] Optionally, in the UL TCI state activation, when the path loss reference signal (PL-RS) is not maintained, the uplink signal transmission requires additional path loss calculation. 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, during the activation of the UL TCI state of the first TRP, the terminal 101 needs to perform uplink path loss measurement and beam measurement.
[0182] Optionally, the RS for UL TCI state activation includes one of the following:
[0183] RS for uplink path loss measurement, where the UL TCI state is a known TCI state;
[0184] RS used for uplink path loss measurement and beam measurement, where the UL TCI state is unknown TCI state.
[0185] For example, when the UL TCI state of the first RS for the first TRP is activated, if the UL TCI state is known, the first RS may be an SSB or CSI-RS for uplink path loss measurement; if the UL TCI state is unknown, the first RS may include an SSB or CSI-RS for uplink path loss measurement, and an SSB or CSI-RS for beam measurement.
[0186] Step S2102 : The network device 102 sends a second RS to the terminal 101 .
[0187] In some embodiments, the second RS is used for activation of the second TCI state.
[0188] Optionally, the second TCI state may represent one of the TCI states of a certain TRP, which may be the same as or different from the first TCI state; or represent the TCI state of a certain TRP among multiple TRPs, which may be different from the TRP corresponding to the first TCI.
[0189] Optionally, when the network device 102 includes a TRP, the second RS may be sent by the TRP.
[0190] Optionally, when the network device 102 includes multiple TRPs, the second RS is sent by the TRP corresponding to the second TCI state. For example, the second RS is used to activate the second TCI state of the second TRP (TRP2), and the second RS is sent by TRP2.
[0191] In some embodiments, when the network device 102 includes one TRP, the second RS is an RS for TRP UL TCI state activation.
[0192] Optionally, the second TCI state is a UL TCI state.
[0193] Optionally, the operation of the terminal 101 during the UL TCI state activation process may refer to the description of step S2101 and will not be repeated here.
[0194] Optionally, the RS for UL TCI state activation includes one of the following:
[0195] RS for uplink path loss measurement, where the UL TCI state is a known TCI state;
[0196] RS used for uplink path loss measurement and beam measurement, where the UL TCI state is unknown TCI state.
[0197] For example, the second RS is an SSB or CSI-RS used for uplink path loss measurement, or the second RS is an SSB or CSI-RS used for uplink path loss measurement and beam measurement.
[0198] In some embodiments, when the network device includes multiple TRPs, the second RS is transmitted by the second TRP among the multiple TRPs.
[0199] Optionally, the second RS is used for TCI state activation of a second TRP (TRP2) and is sent by the second TRP.
[0200] Optionally, 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.
[0201] Optionally, the second RS is one of the following:
[0202] RS with DL TCI state activated for the second TRP;
[0203] RS with UL TCI state activated for the second TRP.
[0204] Optionally, when the DL TCI state of the second RS for the second TRP is activated, the second RS can be used for time-frequency synchronization or beam measurement.
[0205] For example, when the DL TCI state of the second RS for the second TRP is activated, if the DL TCI state is known, the second RS can be an SSB or CSI-RS for time-frequency synchronization; if the DL TCI state is unknown, the second RS can be an SSB or CSI-RS for beam measurement.
[0206] Optionally, when the UL TCI state of the second RS for the second TRP is activated, the second RS can be used for uplink path loss measurement and / or beam measurement.
[0207] For example, when the UL TCI state of the second RS for the second TRP is activated, if the UL TCI state is known, the second RS may be an SSB or CSI-RS for uplink path loss measurement; if the UL TCI state is unknown, the second RS may include an SSB or CSI-RS for uplink path loss measurement, and an SSB or CSI-RS for beam measurement.
[0208] Step S2103: In the conflicting time domain interval, the terminal 101 receives and measures the first RS and / or the second RS.
[0209] In some embodiments, the first RS and the second RS sent by the network device 102 may have a time domain conflict, for example, the transmission periods of the first RS and the second RS are the same, or the transmission periods and starting offsets of the first RS and the second RS are the same.
[0210] Optionally, the time domain conflict or conflict may be that the time domain units where the first RS and the second RS are located overlap or are adjacent.
[0211] In the first example, combined with the description of steps S2101 and S2102, when the network device 102 includes a TRP, the time domain conflict between the first RS and the second RS may be: the RS activated for the DL TCI state of the TRP conflicts with the RS activated for the UL TCI state of the TRP, for example, the SSB used for T / F tracking or beam measurement of the TRP conflicts with the RS used for path loss measurement in the time domain.
[0212] In the second example, in combination with the description of steps S2101 and S2102, when the network device 102 includes multiple TRPs, the time domain conflict between the first RS and the second RS may be one of the following:
[0213] The RS activated in the UL TCI state for TRP1 collides with the RS activated in the UL TCI state for TRP2, for example, the PL-RSs sent by the two TRPs collide in the time domain;
[0214] The RS used for DL TCI state activation of TRP1 collides with the RS used for UL TCI state activation of the second TRP. For example, the SSB used for T / F tracking or beam measurement of TRP1 may collide with the PL-RS used for path loss calculation of TRP2.
[0215] The RS for DL TCI state activation of TRP1 collides with the RS for DL TCI state activation of the second TRP, for example, the SSB for T / F tracking or beam measurement of TRP1 may collide with the SSB for T / F tracking or beam measurement of TRP2.
[0216] In some embodiments, when the possible conflict described above occurs, the terminal 101 may measure one of the first RS and the second RS, and not receive or monitor the other of the first RS and the second RS.
[0217] Optionally, the terminal 101 does not receive or monitor one of the RSs, which may be discarding the RS, or not expecting the network device 102 to send the RS, or believing that the network device 102 does not send the RS.
[0218] In the first example above, when the first RS and the second RS collide in the time domain, the terminal 101 may discard one of them. For example, if the SSB of the TRP used for T / F tracking or beam measurement collide in the time domain with the RS used for path loss measurement, the terminal 101 discards the SSB for T / F tracking or beam measurement, or discards the RS used for path loss measurement.
[0219] In the second example above, when there is a time domain conflict between the first RS and the second RS, the terminal 101 may discard one of them.
[0220] For example, if a time domain collision occurs between the PL-RSs sent by two TRPs, the terminal 101 discards the PL-RS of TRP1 or the PL-RS of TRP2.
[0221] For another example, the SSB used for T / F tracking or beam measurement of TRP1 may conflict with the PL-RS used for path loss calculation of TRP2. Terminal 101 discards the SSB used for T / F tracking or beam measurement of TRP1 or the PL-RS of TRP2.
[0222] For another example, the SSB used for T / F tracking or beam measurement of TRP1 may conflict with the SSB used for T / F tracking or beam measurement of TRP2, and the terminal 101 discards the SSB used for T / F tracking or beam measurement of TRP1 or the SSB used for T / F tracking or beam measurement of TRP2.
[0223] In this embodiment, the terminal 101 cannot complete activation of the first TCI state and the second TCI state at the same time.
[0224] In some embodiments, when the possible conflict described above occurs, the terminal 101 receives and measures the first RS and the second RS.
[0225] Optionally, when the communication frequency band is in frequency range (FR) 1, the terminal 101 may receive the first RS and the second RS simultaneously.
[0226] Optionally, when the communication frequency band is FR2, the terminal 101 measures the first RS and the second RS, which will extend the activation delay.
[0227] 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 activation of the first TCI state and the second TCI state is greater than the activation delay defined for the first TCI state or the second TCI state.
[0228] Optionally, in the conflicting time domain interval, the terminal 101 may alternately receive the first RS and the second RS, such as receiving and measuring the first RS in the first conflicting time domain unit, and receiving and measuring the second RS in the second conflicting time domain unit.
[0229] Optionally, a method for determining or calculating the activation delay of the TCI state may be defined by a protocol.
[0230] Optionally, the network device 102 may indicate the TCI state to be activated this time by sending an activation command to the terminal 101. The TCI state indicated for activation in the activation command may be referred to as a target TCI state or a new TCI state.
[0231] Optionally, the activation delay may include: the period from when the terminal 101 receives the activation command to when the TCI state activation indicated by the activation command is completed. After the terminal 101 completes the TCI state activation, it can be considered that the TCI state switching is completed, and the target TCI state can be applied.
[0232] Optionally, the activation command may be a Media Access Control Element (MAC CE). For example, when the network device includes a TRP, the network device may configure activation of the first TCI state and the second TCI state of the TRP through a MAC CE.
[0233] Optionally, depending on whether the first TCI state or the second TCI state is known or unknown, the activation delay delay determination parameter is different. For example, for the DL TCI state, when the DL TCI state is not in the activated TCI state list of the PDSCH, the terminal 101 needs an additional SSB to obtain the time / frequency of the target TCI state. If the DL TCI state is unknown, the terminal 101 needs to perform additional receive (RX) beam scanning or L1-RSRP measurement based on multiple SSBs or CSI-RS. For another example, for the UL TCI state, when there is no PL-RS to maintain uplink transmission, the terminal 101 needs to calculate the path loss during the activation of the UL TCI state.
[0234] Therefore, in combination with the different situations of the first TCI state and the second TCI state, the corresponding activation delay can be determined by referring to one of the following examples:
[0235] In the first example, if the TCI state is a known DL TCI state, the activation delay corresponding to the TCI state is:
[0236] slot length;
[0237] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T first-SSB Indicates the time between receiving MAC CE and sending the first downlink RS by TRP, T SSB-proc is the downlink RS processing time, with TO k is a constant.
[0238] It is worth noting that the SSB in the formula is sent by the TRP corresponding to the TCI state. For example, if the activation delay of the TCI state of TRP1 needs to be determined, the SSB in the formula is sent by TRP1.
[0239] In the second example, if the TCI state is an unknown DL TCI state, the activation delay corresponding to the TCI state is:
[0240] time slot length;
[0241] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T L1-RSRP Indicates the time of L1-RSRP measurement in beam measurement, T first-SSB Indicates the time between receiving MAC CE and sending the first downlink RS by TRP, T SSB-proc is the downlink RS processing time, With TOu k is a constant.
[0242] In the third example, if the TCI state is a known UL TCI state, the activation delay corresponding to the TCI state is:
[0243] time slot length;
[0244] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T first-target-PL-RS Indicates the duration from decoding the MAC CE to the first PL-RS used for uplink path loss measurement, T target-PL-RS Indicates the downlink PL-RS period, and NM are constants.
[0245] In the fourth example, if the TCI state is an unknown UL TCI state, the activation delay corresponding to the TCI state is:
[0246] time slot length;
[0247] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T first-target-PL-RS Indicates the duration from decoding the MAC CE to the first PL-RS used for uplink path loss measurement, T target-PL-RS Indicates the downlink PL-RS period, T L1-RSRP Indicates the time of L1-RSRP measurement in beam measurement, is a constant.
[0248] 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 extended, such as being greater than the activation delay of the first TCI state determined according to the above example, or greater than the activation delay of the second TCI state.
[0249] Step S2104: During the time period when the first RS and / or the second RS are transmitted, the network device 102 does not send scheduling data to the terminal 101.
[0250] Optionally, during the time period when the first RS and / or the second RS are transmitted, the terminal 101 does not monitor the scheduling data.
[0251] For example, during the time period of the first RS transmission, the terminal 101 does not monitor the scheduling data, or does not expect the network device 102 to send scheduling data, so as not to affect the activation process of the first TCI state; for another example, during the time period of the second RS transmission, the terminal 101 does not monitor the scheduling data, or does not expect the network device 102 to send scheduling data, so as not to affect the activation process of the second TCI state; for another example, during the time period of the first RS transmission and the time period of the second RS transmission, the terminal 101 does not monitor the scheduling data, or does not expect the network device 102 to send scheduling data, so as not to affect the activation process of the two TCI states.
[0252] Optionally, the scheduling data includes, for example, a physical downlink shared channel (PDSCH) or a physical downlink control channel (PDCCH).
[0253] Optionally, this step may be applicable to scheduling constraints in multiple TRP scenarios.
[0254] For example, when the TCI state of two TRPs is activated and Terminal 101 is performing RS measurements for T / F tracking or PL-RS, Terminal 101 cannot be scheduled with data. When Terminal 101 supports the measurement capability of round-trip delay (RTD) > cyclic prefix (CP), the timing offset between the two TRPs may be greater than the CP, and there may be multiple time domain units with scheduling restrictions.
[0255] In some embodiments, the time period includes one of:
[0256] A time domain unit in which the first RS or the second RS is transmitted, wherein the time difference between the first RS and the second RS is less than or equal to the CP;
[0257] A time domain unit, and a time domain unit before or after the time domain unit, wherein the time difference is greater than the CP.
[0258] Optionally, the time difference is used to indicate the difference between the first RS sent by the first TRP and the second RS sent by the second TRP, or the timing offset. The time difference can also be recorded as RTD.
[0259] Optionally, the time domain unit may be a time slot, a symbol, a millisecond, etc.
[0260] In one example, taking the time domain unit as an orthogonal frequency division multiplexing (OFDM) symbol as an example, the terminal 101 does not expect to send uplink channels or signals on some OFDM symbols, such as sending a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH) or a sounding reference signal (SRS), or the terminal 101 does not expect to receive PDCCH, PDSCH, CSI-RS for tracking or CSI-RS for channel quality indication CQI on some OFDM symbols.
[0261] In this example, the OFDM symbols are:
[0262] If the terminal 101 supports the measurement capability of RTD>CP, the part of OFDM symbols includes: the OFDM symbol where the SSB for T / F tracking or the PL-RS for path loss calculation is located, and one OFDM symbol before or after the OFDM symbol;
[0263] If the terminal 101 does not support the measurement capability of RTD>CP, the part of OFDM symbols is the SSB used for T / F tracking or the OFDM symbol where the PL-RS used for path loss calculation is located.

[0326] In which, within a time domain interval in which a time domain conflict occurs between the first RS and the second RS, the first RS and / or the second RS are received and measured by the terminal.
[0327] In some embodiments, when the network device includes a TRP, the first RS is an RS for activating the downlink DL TCI state of the TRP, and the second RS is an RS for activating the uplink UL TCI state of the TRP.
[0328] In some embodiments, when the network device includes multiple TRPs, the first RS is transmitted by the first TRP among the multiple TRPs, and the second RS is transmitted by the second TRP among the multiple TRPs.
[0329] Optionally, the first RS is one of the following:

[0332] Optionally, the second RS is one of the following:

[0345] In some embodiments, RS is one of:
[0346] SSB;
[0347] CSI-RS.
[0348] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 4 b .
[0349] In the method disclosed herein, the UE behavior is defined in scenarios where the RS for DL TCI state activation of a TRP overlaps or is adjacent to the RS for UL TCI state activation of the same TRP, or where the RS for TCI state activation of a TRP overlaps or is adjacent to the RS for TCI state activation of another TRP. To facilitate understanding of the embodiments of the present disclosure, some examples are listed below.
[0350] On the one hand, in a single TRP scenario, a network device (NW) may configure one DL TCI state activation and one UL TCI state activation in one MAC CE, as shown in Examples 1 to 4 below.
[0351] Example 1:
[0352] Based on the current TCI state activation delay requirements, for known DL TCI states, when the DL TCI state is not in the active TCI state list of the PDSCH, the UE requires an additional SSB to obtain the time or frequency of the target TCI state. For unknown DL TCI states, the UE needs to perform additional RX beam scanning (such as L1-RSRP measurement) based on multiple SSBs or CSI-RS. The relevant activation delay requirements are as follows:
[0353] For a known DL TCI state, the activation delay is:
[0354] slot length;
[0355] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T first-SSB Indicates the time between receiving MAC CE and sending the first downlink RS by TRP, T SSB-proc is the downlink RS processing time, with TO k is a constant.
[0356] Optionally, the above time may be a time slot.
[0357] Optionally, if the target TCI state is not in the activated TCI state list corresponding to the downlink channel, TO k =1, otherwise, TO k =0.
[0358] Optionally, TSSB-proc =2ms.
[0359] 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 (switching from the old TCI state to the target TCI state).
[0360] For unknown DL TCI state, the activation delay is:
[0361] time slot length;
[0362] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T L1-RSRP Indicates the time of L1-RSRP measurement in beam measurement, T first-SSB Indicates the time between receiving MAC CE and sending the first downlink RS by TRP, T SSB-proc is the downlink RS processing time, With TOu k is a constant.
[0363] Example 2:
[0364] For the UL TCI state, when the path loss reference signal (PL-RS) for uplink transmission is not maintained, the UE needs to calculate the path loss during the activation of the UL TCI state. The relevant activation delay requirements are as follows:
[0365] For a known UL TCI state, the activation delay is:
[0366] time slot length;
[0367] Where n represents the time when MAC CE is received, T HARQ Indicates the time between MAC CE and the corresponding confirmation feedback information, T first-target-PL-RS Indicates the duration from decoding the MAC CE to the first PL-RS used for uplink path loss measurement, T target-PL-RS Indicates the downlink PL-RS period, and NM are constants.
[0368] For unknown UL TCI states, the receive beam requires an additional L1-RSRP measurement, and the activation delay is:
[0369] time slot length;
[0370] Where n represents the time when MAC CE is received, T HARQIndicates the time between MAC CE and the corresponding confirmation feedback information, T first-target-PL-RS Indicates the duration from decoding the MAC CE to the first PL-RS used for uplink path loss measurement, T target-PL-RS Indicates the downlink PL-RS period, T L1-RSRP Indicates the time of L1-RSRP measurement in beam measurement, is a constant.
[0371] Example 3:
[0372] Combining Examples 1 and 2, for a TRP, if the RS used for its DL TCI state activation overlaps or is adjacent in time domain to the RS used for its UL TCI state activation, the UE may need to discard one of the RSs. If the UE still needs to measure both RSs, the total TCI activation delay will be extended.
[0373] Optionally, the DL TCI state activation process may include: the UE performing time / frequency synchronization or time / frequency tracking, or beam measurement to obtain L1-RSRP, wherein the RS used for DL TCI state activation may be the RS used for time / frequency tracking or L1-RSRP measurement.
[0374] It is also possible that the RS used for time-frequency tracking or L1-RSRP overlaps or is adjacent to the RS used for L1-RSRP measurement.
[0375] Optionally, the activation process of the UL TCI state may include: the UE performing PL-RS measurement, or the UE performing PL-RS and beam measurement.
[0376] When a time domain conflict occurs, the UE's behavior may include the following:
[0377] (1) The UE discards the RS (such as SSB) used for T / F tracking;
[0378] (2) The UE discards the RS (such as SSB or CSI-RS) used for L1-RSRP measurement;
[0379] (3) The UE discards the PL-RS (such as SSB or CSI-RS) used for path loss calculation;
[0380] (4) If the UE will measure two RSs, the total activation time will be extended;
[0381] Among them, for (1) to (3), the UE cannot complete TCI activation of two TCI states at the same time.
[0382] Example 4:
[0383] Based on the third example, the applicability of the TCI state activation is defined, and the applicability depends on whether the TCI state corresponds to the frequency range FR1 or FR2.
[0384] For FR1, when two RSs overlap or are adjacent, the UE can measure both RSs simultaneously without measurement restriction.
[0385] For FR2, when the SSB used for T / F tracking overlaps or is adjacent to the SSB used for PL-RS measurement, the UE needs to measure one of the RSs instead of both; or, there will be a longer activation delay or no other definition, or
[0386] When the SSB used for T / F tracking overlaps or is adjacent to the RS used for L1-RSRP measurement, the UE needs to measure one of the RSs instead of both; or, there will be a longer activation delay or no other definition, or
[0387] When the RS used 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; or, there will be a longer activation delay or no other definition.
[0388] On the other hand, in the multi-TRP (mTRP) scenario, assuming there are two TRPs, TRP1 and TRP2. The NW will configure the TCI state activation for the two TRPs in the following three scenarios:
[0389] (1) DL TCI state (DL-only) activation of TRP1 and UL TCI state (UL-only) activation of TRP2;
[0390] (2) UL TCI state activation (UL-only) of TRP1 and UL TCI state activation (UL-only) of TRP2;
[0391] (3) The DL and UL TCI states of TRP1 are activated, and the DL and UL TCI states of TRP2 are activated.
[0392] The possible time domain conflicts in the three scenarios can be seen in Examples 5 to 10 below.
[0393] Example 5:
[0394] Depending on whether the TCI status is known, or whether T / F tracking is required, or whether path loss calculation is required, the time domain conflict in the above scenario (1) may include the following cases:
[0395] There is a time domain conflict between the SSB used for T / F tracking of TRP1 and the PL-RS of TRP2;
[0396] There is a time domain conflict between the SSB used for T / F tracking in TRP1 and the RS used for L1-RSRP measurement in TRP2.
[0397] Example 6:
[0398] Depending on whether the TCI status is known, or whether T / F tracking is required, or whether path loss calculation is required, the time domain conflict in the above scenario (2) may include the following situations:
[0399] There is a time domain conflict between the RS used for L1-RSRP measurement of TRP1 and the PL-RS of TRP2;
[0400] There is a time domain conflict between the PL-RS of TRP1 and the PL-RS of TRP2.
[0401] Example 7:
[0402] Depending on whether the TCI status is known, or whether T / F tracking is required, or whether path loss calculation is required, the time domain conflict in the above scenario (3) may include the following situations:
[0403] There is a time domain conflict between the SSB used by TRP1 for T / F tracking and the PL-RS of TRP2;
[0404] There is a time domain conflict between the RS used for L1-RSRP measurement of TRP1 and the PL-RS of TRP2;
[0405] There is a time domain conflict between the PL-RS of TRP1 and the PL-RS of TRP2.
[0406] Example 8:
[0407] In combination with Examples 5 to 7, due to UE capability limitations, in these conflicting situations, the UE may need to discard some conflicting RSs, such as by referring to the following optional methods:
[0408] Option 1: The UE discards the RS of TRP1, including the RS used for T / F tracking, L1-RSRP measurement, or path loss calculation;
[0409] Option 2: The UE discards the RS of TRP2, including the RS used for T / F tracking, L1-RSRP measurement, or path loss calculation;
[0410] Option 3: If the UE can measure two or more RSs, the total activation delay will be extended.
[0411] In the above-mentioned optional method 1 and optional method 2, the UE cannot complete the TCI state activation of two TRPs at the same time.
[0412] Example 9:
[0413] Based on Example 8, define the applicability of TCI status activation:
[0414] When the SSB used for T / F tracking overlaps or is adjacent to the PL-RS of two TRPs, the UE needs to measure one of the RSs instead of both RSs; or, there will be a longer activation delay or no other definition, or
[0415] When the SSBs for T / F tracking of two TRPs overlap or are adjacent to the RSs used for L1-RSRP measurement, the UE needs to measure the RS of one TRP instead of the RSs of two TRPs; or, there will be a longer activation delay or no other definition, or
[0416] When the RS used for L1-RSRP measurement overlaps or is adjacent to the PL-RS of two TRPs, the UE needs to measure the RS of one TRP instead of the RS of both TRPs; or, there will be a longer activation delay or no other definition, or
[0417] When the PL-RSs of two TRPs overlap or are adjacent, the UE needs to measure one of the RSs instead of both RSs; or, there will be a longer activation delay or no other definition, or
[0418] When the PL-RS of one TRP overlaps with the RS used for L1-RSRP measurement, PL-RS, RS used for beam failure detection (BFD) or candidate beam detection (CBD), or RS used for radio link monitoring (RLM) of another TRP, the UE needs to measure the RS of one of the TRPs instead of the RSs of both TRPs. Alternatively, there will be a longer activation delay or no other definition.
[0419] Example 10:
[0420] Based on the above example, there are scheduling restrictions in the mTRP scenario.
[0421] During the TCI state activation period between two TRPs, when the UE is performing measurements on the RS for T / F tracking or PL-RS, the UE cannot be scheduled with data. When the UE supports the measurement capability of RTD>CP, the timing offset between the two TRPs may be larger than the CP, then an extra symbol needs to be considered when defining the scheduling restrictions.
[0422] For example, scheduling restrictions include:
[0423] Before the UE completes activation of both TCI states, the UE is not expected to transmit PUCCH, PUSCH, or SRS on the relevant OFDM symbols, or is not expected to receive PDCCH, PDSCH, CSI-RS for tracking, or CSI-RS for CQI on the relevant OFDM symbols, where the relevant OFDM symbols are:
[0424] OFDM symbol of SSB for T / F tracking or PL-RS for path loss calculation, and one OFDM symbol before or after, where the UE supports RTD > CP;
[0425] OFDM symbols for SSBs used for T / F tracking, SSBs for L1-RSRP measurement, or PL-RS for path loss calculation, where the UE does not support RTD>CP.
