Description

Technical Field

[0001] The subject matter disclosed herein relates generally to wireless communications, and more particularly to methods and apparatus for power control of SRS transmissions for non-codebook based UL transmissions. Background Art

[0003] A unified TCI framework is used in NR Release 17 to support non-codebook (nCB) based UL transmission. To support nCB based UL transmission, one or more SRS resource sets (each SRS resource set includes one or more SRS resources) for non-codebook can be configured for the UE in the BWP of the serving cell. Each SRS resource set can be associated with the configured NZP CSI-RS resource to calculate the precoder for SRS transmission of the gNB to select the appropriate UL precoder for subsequent PUSCH transmission. In addition, each SRS resource (in each SRS resource set) can be configured with a TCI state to determine the UL TX spatial filter, i.e., UL beam, for SRS transmission. Each TCI state is associated with the PL-RS and the power control parameters for the UE to determine the transmit power for SRS transmission. With the unified TCI framework, the unified TCI state for the BWP of the serving cell can be indicated by DCI or MAC CE or RRC signaling for all PUSCH and PUCCH transmissions in the BWP of the serving cell. When the SRS resource set is not configured with a TCI state, the SRS resource set can also be configured to follow the indicated unified TCI state through RRC signaling. If the SRS resource is configured with a TCI state or is indicated to follow the indicated unified TCI state, the UE shall transmit the SRS at a power determined by the power control parameters associated with the TCI state (or the indicated unified TCI state). However, when the SRS resource set is configured with an associated NZP CSI-RS, the UE should not expect to be configured with a TCI state or be indicated to follow the indicated unified TCI state to avoid RX and TX beam misalignment. In addition, when there are more than two ports, the associated NZP CSI-RS cannot be used as PL-RS because it will increase the UE complexity. In addition, how to determine other power control parameters including P0, alpha and closed-loop index is unknown.

[0029] The first embodiment involves a single TRP scenario.

[0030] In a single TRP scenario, the UE is indicated with a unified TCI state. As specified in 3GPP TS38.213, for the BWP of the serving cell, the indicated unified TCI state (which can be a joint TCI state for both UL transmission and DL reception, or a UL TCI state dedicated to UL transmission) is associated with (or includes) the PL-RS of the UE to obtain a downlink path loss estimate for PUSCH, PUCCH and SRS transmissions. The obtained downlink path loss estimate can be used for non-codebook SRS transmissions configured with associated NZP CSI-RS resources. This means that the UE determines the RS index for obtaining a downlink path loss estimate for SRS transmission based on the PL-RS associated with or included in the indicated unified TCI state. .

[0031] Other power control parameters, including P0 (which configures the target received power on the TRP side), (which is the partial path loss compensation factor) and the closed loop index (or power control adjustment state) , can be obtained in the following way.

[0032] Multiple uplink power control parameter sets (e.g., ), each uplink power control parameter set has a power control parameter set identifier (eg, Each uplink power control parameter set includes a power control parameter set for PUSCH (eg, ), a power control parameter set for PUCCH (e.g., ), and a power control parameter set for SRS (eg, ). , and Each of them contains P0, and One of multiple uplink power control parameter sets (i.e., ) may be associated with the indicated unified TCI state. In this case, the power control parameter set for SRS in the uplink power control parameter set associated with the indicated unified TCI state (eg, ) can be used for SRS transmission of nCBs configured with associated NZP CSI-RS resources. This means that the UE is used to calculate the SRS transmission transmit power corresponding to the non-codebook SRS resource set configured with associated NZP CSI-RS resources. , And SRS power control adjustment status The value of is obtained from the power control parameter set for SRS associated with the indicated unified TCI state, wherein the power control parameter set for SRS includes P0, and closed loop index Therefore, if the power control parameter set for SRS (e.g., ) is associated with the indicated unified TCI status, then , as well as The value of is determined by the associated unified TCI state indicated. supply.

[0033] if is not associated with the indicated unified TCI status, the default The following options can be considered.

[0034] Option 1-1: If only one dedicated The BWP is configured for the serving cell and is not configured in the serving cell. List, then , as well as The value of In supply.

[0035] Option 1-2: If an uplink power control parameter set list is configured in the serving cell (e.g. list) and dedicated If no BWP is configured for the serving cell, , as well as The value is determined by the number of nodes with the lowest collection ID (for example, the lowest ) in the uplink power control parameter set list configured in the serving cell In supply.

[0036] The second embodiment relates to a multi-TRP mode based on multi-DCI in a multi-TRP scenario.

[0037] Multi-TRP based non-codebook PUSCH transmission with unified TCI framework will be specified in NR Release 18. Two SRS resource sets for non-codebook can be configured in the BWP of the serving cell. In addition, two unified TCI states should be indicated in the BWP of the serving cell.

[0038] In multi-TRP mode based on multi-DCI, higher layer parameters are configured for each CORESET , which identifies the time-frequency resource set used for PDCCH transmission with TRP difference. In this mode, each TRP can independently transmit DCI that schedules PDSCH transmitted from the same TRP or PUSCH transmitted to the same TRP. Each of the two SRS resource sets is associated with For example, the first SRS resource set is associated with The value 0 is associated with the second SRS resource set. In addition, each of the two indicated unified TCI states is associated with Value associated.

[0039] Each of the two indicated unified TCI states is associated with a PL-RS and may be further associated with a set of uplink power control parameters (e.g., ) are associated.

[0040] When each of the two SRS resource sets for nCB is associated with an NZP CSI-RS resource, the UE shall determine, based on the PL-RS associated with the indicated unified TCI state, the RS index used to obtain the downlink path loss estimate for the SRS transmission corresponding to the SRS resource set , the indicated unified TCI state is the same as and associated with the SRS resource set This means that the UE determines the RS index for obtaining the downlink path loss estimate for the SRS transmission corresponding to the first SRS resource set based on the PL-RS associated with the indicated unified TCI state. , the indicated unified TCI state is the same as and associated with the first SRS resource set Values ​​(for example, value 0), and determining, based on the PL-RS associated with the indicated unified TCI state, an RS index for obtaining a downlink path loss estimate for an SRS transmission corresponding to a second SRS resource set. , the indicated unified TCI state is associated with the second SRS resource set Same value Values ​​(for example, Value 1) is associated.

In Obtain the SRS transmission corresponding to the first SRS resource set , as well as , the indicated unified TCI state is the same as and associated with the first SRS resource set Values ​​(for example, value 0) and from the In Obtaining the SRS transmission corresponding to the second SRS resource set , as well as , the indicated unified TCI state is the same as and associated with the second SRS resource set Values ​​(for example, value 0).

[0042] If the indicated unified TCI state does not match the uplink power control parameter set (e.g., ), the default The following options can be considered:

[0043] Option 2-1: If two dedicated (For example, the first and second ) is configured for the BWP of the serving cell, and each and Values ​​are associated (for example, the first and The value 0 is associated, and the second and value 1), the UE selects from the same SRS resource set as Value associated with the dedicated In get , as well as This means that the UE receives the same SRS resource set as the first SRS resource set. Values ​​(for example, Value 0) associated with a dedicated In Obtaining the SRS transmission corresponding to the first SRS resource set , as well as , and from the same SRS resource set as the second SRS resource set Values ​​(for example, Value 1) Associated with the dedicated In Obtaining the SRS transmission corresponding to the second SRS resource set , as well as .

[0044] Option 2-2: If two List (for example, the first List and second Lists) are configured for serving cells, and each list is associated with Values ​​are associated (for example, the first and The value 0 is associated, and the second and value 1), the UE selects from the same SRS resource set as Value associated The list with the lowest of In get , as well as This means that the UE is connected to the same SRS resource set as the first Values ​​(for example, Value 0) associated List (for example, the first list) with the lowest of In Obtaining the SRS transmission corresponding to the first SRS resource set , as well as , and from the same SRS resource set as the second SRS resource set Values ​​(for example, Value 1) Associated List (for example, the second list) with the lowest of In Obtaining the SRS transmission corresponding to the second SRS resource set , as well as .

[0046] The third embodiment relates to a multi-TRP mode based on a single DCI in a multi-TRP scenario.

[0047] In multi-TRP mode based on single DCI, Should not be configured. In this mode, one TRP can transmit DCI that schedules PDSCH transmitted from two TRPs. Each of the two SRS resource sets is associated with one of the two indicated unified TCI states in a fixed manner. For example, assuming that the two SRS resource sets are a first SRS resource set (e.g., an SRS resource set with a lower SRS resource set ID) and a second SRS resource set (e.g., an SRS resource set with a higher SRS resource set ID), and the two indicated unified TCI states are a first indicated unified TCI state and a second indicated unified TCI state, the first SRS resource set is associated with the first indicated unified TCI state, and the second SRS resource set is associated with the second indicated unified TCI state.

[0049] When each of the first SRS resource set for nCB and the second SRS resource set for nCB is associated with an NZP CSI-RS resource (e.g., the first SRS resource set for nCB is associated with a first NZP CSI-RS resource and the second SRS resource set for nCB is associated with a second NZP CSI-RS resource), the UE shall determine, based on the PL-RS associated with the indicated unified TCI state associated with the SRS resource set, the RS index for obtaining a downlink path loss estimate for the SRS transmission corresponding to each SRS resource set For example, the UE shall determine, based on the PL-RS associated with the first indicated unified TCI state associated with the first SRS resource set, an RS index for obtaining a downlink path loss estimate for an SRS transmission corresponding to the first SRS resource set. , and determining, based on the PL-RS associated with the second indicated unified TCI state associated with the second SRS resource set, an RS index for obtaining a downlink path loss estimate for an SRS transmission corresponding to the second SRS resource set .

[0050] If the indicated unified TCI state (the first indicated unified TCI state or the second indicated unified TCI state) is further associated with an uplink power control parameter set (eg, ), the UE shall select from the state associated with the indicated unified TCI state associated with the SRS resource set. In Get the SRS resource set corresponding to the SRS transmission , as well as This means that the UE switches from an indicated unified TCI state associated with the first SRS resource set (eg, the first indicated unified TCI state) to an indicated unified TCI state associated with the first SRS resource set.
