Description

[Technical Field]

[0001] This specification relates generally to wireless communications, and more particularly to fifth generation (5G) wireless communications. [Background technology]

[0002] Generally, a gNode B (gNB) uses a fixed transmit power (e.g., power spectral density (PSD)) for downlink (DL) transmission, which may not be beneficial to new radio (NW) power consumption.

When dynamic power adjustment is adopted, semi-static parameters, such as a power offset between a physical downlink shared channel (PDSCH) and a channel status information reference signal (CSI-RS), may result in inaccurate CSI reporting or feedback.

DETAILED DESCRIPTION OF THE INVENTION

[0038] A UE may be configured according to one or more CSI reporting configurations by CSI-ReportConfig signaling. A CSI-ReportConfig may be associated with one or more CSI-RS resource configurations by CSI-resourceConfigID. A CSI-RS resource configuration is configured by CSI-ResourceConfig signaling.

[0039] A UE may be configured with one or more NZP CSI-RS resource set configurations, as indicated by the higher layer parameters CSI-ResourceConfig and NZP-CSI-RS-ResourceSet. Each NZP CSI-RS resource set may contain two or more NZP CSI-RS resources.

[0040] The IE (information element) CSI-MeasConfig is used to configure CSI-RS (reference signals) belonging to the serving cell in which the CSI-MeasConfig is included.

[0041] In one embodiment, a user equipment (UE) receives signaling (e.g., from a gNB) and performs corresponding operations. The signaling may include at least one of radio resource control (RRC) signaling, medium access control (MAC CE), or downlink control information (DCI). The corresponding operations may include at least one of measurements or reports.

[0042] In some embodiments, the measurements include CSI measurements and the reports include CSI reports. In some embodiments, the measurements include beam measurements and the reports include beam reports.

[0043] In some embodiments, the RRC, MAC CE, or DCI signaling includes at least one of a threshold associated with the radio link quality, a number of resources for beam measurements, a timer value associated with the radio link measurements, or a counter value associated with the radio link measurements.

[0044] In some embodiments, the radio link measurements include CSI-RS measurements for L1-RSRP or L1-SINR.

[0045] In some embodiments, the radio link measurements include SSB measurements for L1-RSRP or L1-SINR.

[0046] In some embodiments, the threshold associated with the radio link quality comprises at least one of a threshold for assessing whether the radio link quality is synchronized or not, or a threshold for assessing whether the radio link quality is out of synchronization.

[0047] In some embodiments, the timer includes timer T310 or timer T312. In some embodiments, the counter includes counter N310 or counter N312.

[0048] In some embodiments, the RRC, MAC CE, or DCI signaling includes at least one of a scaling factor of a threshold associated with the radio link quality, a number of resources for beam measurements, a scaling factor of a timer value associated with the radio link measurements, or a scaling factor of a counter value associated with the radio link measurements.

[0049] In one embodiment, the gNB transmits signaling (e.g., to the UE), the signaling including at least one of RRC signaling, MAC CE, or downlink control information (DCI).

[0050] In one embodiment, the gNB receives a CSI report from the UE based on signaling. In one embodiment, the RRC signaling includes at least one of one or more CSI resource configurations, one or more CSI reporting configurations, a first power offset set, a second power offset set, a third power offset set, a port set, or a TCI (Transmission Configuration Indicator) state set.

[0051] In one embodiment, the CSI resources include at least one of one or more CSI-RS resources, one or more CSI-RS resource sets, and one or more CSI-RS resource configurations.

[0052] In some embodiments, the power offset within each CSI resource is configured independently. CSI resources with different power offsets and / or different numbers of ports may be configured for CSI-RS measurements and CSI reporting. In one embodiment, the UE drives CSI feedback with different power offsets and / or different numbers of ports and / or different numbers of TCI states via CSI resource updates. In one embodiment, the UE drives CSI feedback on all configured CSI resources.

[0053] In one embodiment, the CSI report includes at least one of a multi-CSI report or a single-CSI report. If multi-CSI reporting is configured, the number of ports and / or power offset associated with the multi-CSI reporting configuration may vary.

[0054] In one embodiment, the power offsets described herein correspond to at least one of a power control offset value in a first power offset set, a power offset value in a second power offset set, and an additional power offset in a third power offset set.

[0055] In one embodiment, each power offset set includes one or more power offsets. In some embodiments, a power offset set includes only one power offset. In some other embodiments, a power offset set is a power offset set that includes one or more power offsets.

[0056] In one embodiment, the first power offset set includes one or more candidate power control offsets that are assumed ratios of PDSCH EPRE (Physical Downlink Shared Channel Energy per Resource Element) to NZP CSI-RS EPRE (Non-Zero Power CSI-RS Energy per Resource Element).

[0057] In one embodiment, the parameters powerControlOffset (which is the assumed ratio of PDSCH EPRE to NZP CSI-RS EPRE when the UE derives CSI feedback and takes values ​​in the range [-8,15] dB with a 1 dB step size) and powerControlOffsetSS (which is the assumed ratio of NZP CSI-RS EPRE to SS / PBCH block EPRE), which allow the UE to assume non-zero transmit power for CSI-RS resources, are configured via the higher layer parameters NZP-CSI-RS-Resource, CSI-ResourceConfig, and NZP-CSI-RS-ResourceSet for each CSI-RS resource configuration.

[0058] In one embodiment, the second power offset set includes one or more candidate power offsets that are assumed ratios of NZP CSI-RS EPRE to SS / PBCH (Synchronization Signal / Physical Broadcast Channel) block EPRE.

[0059] In one embodiment, the third power offset set includes one or more candidate additional power offsets used to compensate for a power control offset (an assumed ratio of PDSCH EPRE to NZP CSI-RS EPRE or an assumed ratio of NZP CSI-RS EPRE to SS / PBCH block EPRE).

[0060] In one embodiment, the third power offset set is a compensation for powerControlOffset. The sum of the third power offset and powerControlOffset is the expected ratio of PDSCH EPRE to NZP CSI-RS EPRE actually used when the UE derives CSI feedback. If a power offset greater than 1 / 3 is configured, the configured powerControlOffset and each third power offset value in the third offset list are added together. For example, if powerControlOffset is configured with a value of −2 dB and the third power offset set is configured as a power offset list having values ​​{−3, 0, 3, 6} dB, for CQI calculation, the expected ratio of PDSCH EPRE to NZP CSI-RS EPRE actually used when the UE derives CSI feedback should be the configured powerControlOffset value plus the configured third power offset value in the third power offset list, which should take the value {−5, −2, 1, 4} dB.

[0061] In one embodiment, the range of values ​​for the third power offset is [−X, X] dB with a 1 dB step size, where X may be 23.

[0062] In one embodiment, the UE does not expect the combination of powerControlOffset and the third power offset to exceed the range of [-8, 15] dB with a 1 dB step size. The sum of the configured powerControlOffset value and the value in the third power offset set must be within the range of [-8, 15] dB.

[0063] In one embodiment, at least one of the first power offset set, the second power offset set, and the third power offset set is configured in at least one of the NZP-CSI-RS-Resource, the NZP-CSI-RS-ResourceSet, or the CSI-ResourceConfig.

[0064] In one embodiment, the first power offset set, the second power offset set, and the third power offset set are configured in an NZP-CSI-RS resource. In another embodiment, the first power offset set and the second power offset set are configured in an NZP-CSI-RS resource. In another embodiment, the third power offset set is configured in an NZP-CSI-RS resource, and each CSI-RS resource includes the third power offset set. Candidate power offsets in the third power offset set may act on the current CSI-RS resource.

[0065] In one embodiment, when more than one CSI-RS resource is configured in a CSI-RS resource set, a third power offset set may be configured in an NZP-CSI-RS-ResourceSet, and the candidate power offsets in the third power offset set may affect all CSI-RS resources associated with the CSI-RS resource set. In another embodiment, the third power offset set may be configured in a CSI-ResourceConfig, and the candidate power offsets in the third power offset set may affect all CSI-RS resources associated with the CSI-ResourceConfig.

[0066] In some embodiments, the TCI state set includes one or more TCI states. In some examples, the TCI state is associated with a CSI-RS, a PRS, or an SRS. In some examples, the TCI state provides at least one of a QCL (quasi-co-location) source, a QCL type, or spatial information. In some embodiments, the TCI state can be “spatial information.”

[0067] In one embodiment, the MAC CE indicates the enable / disable state (activated / deactivated or available / unavailable) of one or more power offsets in at least one of the first power offset set, the second power offset set, and the third power offset set, and / or the enable / disable (enabled / disabled) state of one or more CSI resources, and / or the enable / disable (activated / deactivated or available / unavailable) of one or more TCI states in the TCI state set.

[0068] In one embodiment, the MAC CE may have at least one of the following fields: In one embodiment, the first field is for indicating the identity of the serving cell to which the MAC CE applies.

[0069] In one embodiment, the second field is to indicate the BWP (Bandwidth Part) ID to which the MAC CE applies.

[0070] In one embodiment, the third field is for indicating the availability / unavailability of the power offsets in the first power offset set.

[0071] In one embodiment, two or more power offsets in the first power offset set may be indicated as available.

[0072] In one embodiment, the fourth field is for indicating the availability / unavailability of the power offsets in the second power offset set.

[0073] In one embodiment, two or more power offsets in the second power offset set may be indicated as available.

[0074] In one embodiment, the fifth field is for indicating the availability / unavailability of the power offsets in the third power offset set.

[0075] In one embodiment, two or more power offsets in the third power offset set may be indicated as available.

[0076] In one embodiment, the sixth field is for identifying the CSI resource configuration.

[0077] In one embodiment, the sixth field is: one or more CSI-RS resource IDs; one or more CSI-RS resource set IDs; includes at least one of the one or more CSI-ResourceConfig IDs; In one embodiment, the seventh field is for indicating the updated CSI resource.

[0078] In one embodiment, the seventh field indicates the activation and / or deactivation of CSI resources.

[0079] In some embodiments, the seventh field is a Ci field. The Ci field corresponds to an identity i (e.g., an integer). The identity includes at least one of a CSI-RS resource ID, a CSI-RS resource set ID, or a CSI-ResourceConfig ID. Each identity is associated with a CSI resource. The Ci field is set to 1 to indicate that the corresponding CSI resource is enabled / activated, and the Ci field is set to 0 to indicate that the corresponding CSI resource is disabled / deactivated. Figure 1 shows an example of signaling according to one embodiment of the present disclosure, where "Oct" may specify "octal."

[0080] In one embodiment, the eighth field is for indicating the availability / unavailability of a TCI state in the TCI state set.

[0081] In one embodiment, an inverted field may also be included in the MAC CE, with the bits in this field set to 0.

[0082] In one embodiment, the MAC CE indicates the available / unavailable status of a power offset by indicating the available / unavailable status of a power offset value in a power offset set. In one embodiment, the MAC CE indicates the available / unavailable status of a power offset by indicating the available / unavailable status of a CSI resource associated with the power offset.

[0083] In one embodiment, the MAC CE is used for at least one of periodic CSI-RS, semi-persistent (SP) CSI-RS, or aperiodic CSI-RS.

[0084] In one embodiment, MAC CE is not used for aperiodic CSI-RS, and signaling may only be used for SP CSI-RS resources and periodic CSI-RS.

[0085] In one embodiment, MAC CE is not used for aperiodic CSI-RS and SP CSI-RS, and signaling may be used only for periodic CSI-RS.

[0086] In some other examples, the MAC CE may be used for at least one of periodic SRS, semi-persistent (SP) SRS (Sounding Reference Signal), or aperiodic SRS.

[0087] In some other examples, the MAC CE may be used for a PRS (Positioning Reference Signal). In one embodiment, the bits in any of the third, fourth, and fifth fields are in the form of a bitmap. Each bit in the field can correspond to a power offset or a group of power offsets. A bit may be set to 1 to indicate that the corresponding power offset is enabled / activated, and a bit may be set to 0 to indicate that the corresponding power offset is disabled / deactivated. In one embodiment, the third field has a size of M bits, each bit corresponds to one power offset in the first power offset set, and the ith bit (T i-1 ) indicates whether the i-th configured power offset in the first power offset set is enabled / activated. If the number of power offsets is less than i, the MAC entity may ignore the i-th bit.

[0088] FIG. 2 illustrates an example of signaling according to one embodiment of the present disclosure, where "Oct" may specify "octal."

[0089] In some embodiments, two or more CSI-RS resource IDs and power offset indications corresponding to the CSI-RS resource with ID 0 are indicated in the MAC CE. The CSI-RS resource IDs include at least one of a CSI-RS resource ID, a CSI-RS resource set ID, or a CSI-ResourceConfig ID. The power offset indications include at least one of an indication indicating a first power offset set, an indication indicating a second power offset set, or an indication indicating a third power offset set.

[0090] In some embodiments, one or more power offsets are indicated by the MAC CE. In some embodiments, the i-th power offset corresponds to the i-th CSI-RS resource, where i is a non-negative integer. In some embodiments, the i-th CSI-RS resource is determined by higher layer signaling. In some embodiments, the i-th CSI-RS resource is determined by the order of the CSI-RS resources indicated by the MAC CE.

[0091] In some embodiments, one or more TCI states are indicated by the MAC CE. In some embodiments, the i-th TCI state corresponds to the i-th resource, where i is a non-negative integer. In some embodiments, the i-th resource is determined by higher layer signaling. In some examples, the resources include resources for PDCCH, CSI-RS, PRS, DM-RS, and / or SRS. In some embodiments, the i-th resource is determined by the order of CSI-RS resources indicated by the MAC CE.

[0092] 3 and 4 show example signaling according to one embodiment of the present disclosure, where "Oct" may specify "octal." In some embodiments, the MAC CE includes a sixth field indicating a CSI resource ID (indicated by a bold frame), and the MAC CE indicates the availability / unavailability of a power offset corresponding to the CSI resource having the indicated ID.

[0093] FIG. 5 illustrates an example of signaling according to one embodiment of the present disclosure, where "Oct" may specify "octal."

[0094] The MAC CE indication is valid under at least one of the following conditions: The MAC CE indication being valid indicates at least one of: that CSI measurements are to be performed by the wireless communications terminal using one or more indicated power offsets, that CSI measurements are to be performed by the wireless communications terminal using updated CSI resources, or that CSI measurements are to be performed by the wireless communications terminal using updated CSI resources.

[0095] In one embodiment, the indication becomes effective after a certain duration. In one embodiment, the duration may be a fixed value, for example, 3 ms after the MAC CE indication HARQ-ACK (hybrid automatic repeat request acknowledgment). In one embodiment, the duration is determined by at least one of the SCS, UE capabilities. In one embodiment, the duration is a*2 n where a is non-negative and n is greater than or equal to 0.

[0096] In one embodiment, the indication takes effect from the next CSI-RS measurement occasion. In one embodiment, the indication remains valid until a CSI report is triggered, which may be a semi-persistent CSI report or an aperiodic CSI report.

[0097] For example, if the MAC CE indicates the availability / unavailability of a power offset and / or the activation / deactivation of a CSI resource, enabling the indication includes the UE performing CSI measurements using the indicated power offset and / or the UE performing CSI measurements using the updated CSI resource.

[0098] In one embodiment, when the MAC CE indicates the availability / unavailability of a power offset and / or the activation / deactivation of a CSI resource, the UE derives CSI feedback with the indicated power offset and / or derives updated CSI resources under at least one of the following conditions:

[0099] In one embodiment, the indication in the MAC CE is enabled. In one embodiment, the old power offset value is applied until the new value takes effect.

[0100] In one embodiment, the UE derives CSI feedback using old CSI resources until updated CSI resources become valid.
