Adaptable configuration for periodic and semi-persistent layer one measurement reports
This disclosure provides systems, methods, and devices for wireless communication that support adaptable configuration for periodic and semi-persistent layer 1 (L1) measurement reporting. In a first aspect, a method of wireless communication includes a user equipment receiving an L1 measurement report configuration via radio resource control (RRC) signaling from a network entity. The L1 measurement report configuration includes configuration of one or more report occasions for L1 measurement report transmissions. The UE or network entity may then identify a dynamic modification indication that identifies a modification to one or more upcoming report occasions. The UE may transmit an L1 measurement report to the network entity in the upcoming report occasions according to the modification. Other aspects and features are also claimed and described.
1 . A method of wireless communication performed by a user equipment (UE), the method comprising:
receiving, by the UE, a layer 1 (L1) measurement report configuration via radio resource control (RRC) signaling, wherein the L1 measurement report configuration includes configuration of one or more report occasions for L1 measurement report transmission from the UE;
identifying, by the UE, a dynamic modification indication, wherein the dynamic modification indication identifies a modification to one or more upcoming report occasions of the one or more report occasions, wherein the modification includes a shift in frequency of reporting of the one or more upcoming report occasions; and
transmitting, by the UE, an L1 measurement report in the one or more upcoming report occasions according to the modification.
2 . The method of claim 1 , wherein the modification to the one or more upcoming report occasions includes one of:
the modification of a single upcoming report occasion of the one or more report occasions; or
a semi-persistent modification of the one or more upcoming report occasions of the one or more report occasions occurring after identification of the dynamic modification indication.
3 . The method of 1 , wherein the modification includes one of:
cancellation of the one or more upcoming report occasions;
a shift in frequency of the one or more upcoming report occasions;
a configuration modification that modifies one or more configuration parameters within the L1 measurement report configuration;
a predetermined number of additional report occasions to add to the one or more report occasions;
one or more beam changes; or
a pattern of report occasions to skip over a predetermined number of report occasions of the one or more upcoming report occasions.
4 . The method of claim 3 , further including:
detecting, by the UE, an omitted report occasion of the one or more report occasions caused by the modification; and
increasing, by the UE, a number of locations for one of physical downlink control channel (PDCCH) monitoring and scheduling requests (SRs).
5 . The method of claim 4 , wherein the L1 measurement report configuration further includes additional location configuration for the one of the PDCCH monitoring and the SRs associated with detection of the omitted report occasion.
6 . The method of claim 1 , wherein the identifying the dynamic modification indication includes one of:
receiving a downlink dynamic modification signal from a serving network entity;
determining the modification of the one or more report occasions, and transmitting an uplink dynamic modification signal to the serving network entity; or
detecting one or more channel conditions related to the configuration of the one or more report occasions, and determining the modification using one or more preconfigured rules associated with the one or more channel conditions.
7 . The method of claim 6 , wherein at least one preconfigured rules of the one or more preconfigured rules defines the modification to include moving at least one report occasion of the one or more report occasions to an uplink channel less than a preconfigured time from an original location of the at least one report occasion, wherein the modification defines the at least one report occasion to be multiplexed on the uplink channel and wherein the preconfigured time corresponds to a minimum time reserved for the UE to process a dynamic modification indication.
8 . The method of claim 7 , wherein the UE is configured with a preconfigured time to apply the modification, such that the transmitting the L1 measurement report occurs at least the preconfigured time from the identifying the dynamic modification indication.
9 . The method of claim 8 , wherein the preconfigured time is selected according to one or more capabilities of the UE.
10 . The method of claim 1 , wherein the one or more report occasions are configured by the L1 measurement report configuration for one of:
periodic L1 measurement reporting; or
semi-persistent L1 measurement reporting.
11 . A user equipment (UE) configured for wireless communication, the UE comprising:
at least one processor; and
a memory coupled to the at least one processor,
wherein the at least one processor is configured:
to receive, by the UE, a layer 1 (L1) measurement report configuration via radio resource control (RRC) signaling, wherein the L1 measurement report configuration includes configuration of one or more report occasions for L1 measurement report transmission from the UE;
to identify, by the UE, a dynamic modification indication, wherein the dynamic modification indication identifies a modification to one or more upcoming report occasions of the one or more report occasions, wherein the modification includes a shift in frequency of reporting of the one or more upcoming report occasions; and
to transmit, by the UE, an L1 measurement report in the one or more upcoming report occasions according to the modification.
12 . The UE of claim 11 , wherein the modification to the one or more upcoming report occasions includes one of:
the modification of a single upcoming report occasion of the one or more report occasions; or
a semi-persistent modification of the one or more upcoming report occasions of the one or more report occasions occurring after identification of the dynamic modification indication.
13 . The UE of 11 , wherein the modification includes one of:
cancellation of the one or more upcoming report occasions;
a shift in time of the one or more upcoming report occasions;
a configuration modification that modifies one or more configuration parameters within the L1 measurement report configuration;
a predetermined number of additional report occasions to add to the one or more report occasions;
one or more beam changes; or
a pattern of report occasions to skip over a predetermined number of report occasions of the one or more upcoming report occasions.
14 . The UE of claim 13 , further including configuration of the at least one processor:
to detect, by the UE, an omitted report occasion of the one or more report occasions caused by the modification; and
to increase, by the UE, a number of locations for one of physical downlink control channel (PDCCH) monitoring and scheduling requests (SRs).
15 . The UE of claim 11 , wherein the configuration of the at least one processor to identify the dynamic modification indication includes configuration of the at least one processor to one of:
receive a downlink dynamic modification signal from a serving network entity;
determine the modification of the one or more report occasions, and transmit an uplink dynamic modification signal to the serving network entity; or
detect one or more channel conditions related to the configuration of the one or more report occasions, and determine the modification using one or more preconfigured rules associated with the one or more channel conditions.
16 . The UE of claim 11 , wherein the one or more report occasions are configured by the L1 measurement report configuration for one of:
periodic L1 measurement reporting; or
semi-persistent L1 measurement reporting.
