Transmission opportunities during measurement gaps
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus, e.g., a base station, maybe configured to obtain UE information of a UE. The apparatus may configure one or more parameters of one or more measurement gaps based on the UE information, and transmit, to the UE, measurement gap information on the one or more measurement gaps. The measurement gap information may include the one or more configured parameters. In another aspect of the disclosure, a UE maybe configured to transmit, to a base station, UE information of the UE. The UE may receive a measurement request from the base station in response to the UE information, where the measurement request includes configuration information for one or more measurement gaps based on the transmitted UE information. The UE may measure one or more reference signals during at least one measurement gap.
1. A method of wireless communication by a base station, comprising:
obtaining user equipment (UE) information of a UE;
configuring one or more parameters of one or more measurement gaps based on the UE information including setting a measurement gap duration of at least one of the one or more measurement gaps to a short duration when the UE information indicates that the UE is measuring a current serving cell and setting the measurement gap duration of the at least one of the one or more measurement gaps to a long duration when the UE information indicates that the UE is attempting to detect another cell; and
transmitting, to the UE, a measurement request including measurement gap information on the one or more measurement gaps.
2. The method of claim 1 , wherein the configuring the one or more parameters of the one or more measurement gaps further comprises:
configuring a frequency of occurrence of the at least one of the one or more measurement gaps having a long duration to a first occurrence frequency; and
configuring a frequency of occurrence of the at least one of the one or more measurement gaps having a short duration to a second occurrence frequency,
wherein the first occurrence frequency is less than the second occurrence frequency, and
wherein the measurement gap information includes information indicating at least one of the first frequency of occurrence or the second frequency of occurrence.
3. The method of claim 1 , wherein the configuring the one or more parameters of the one or more measurement gaps comprises:
determining a mobility state of the UE based on the UE information, the UE information including at least one of uplink reference signal, or feedback information from the UE;
setting a measurement gap duration of at least one of the one or more measurement gaps to a short duration and a frequency of occurrence of the at least one of the one or more measurement gaps to be high when the mobility state of the UE indicates that the UE is stationary; and
setting the measurement gap duration of the at least one of the one or more measurement gaps to a long duration and a frequency of occurrence of the at least one of the one or more measurement gaps to be high when the mobility state indicates that the UE is mobile.
4. The method of claim 1 , wherein the configuring the one or more parameters of the one or more measurement gaps comprises:
determining that a high priority application is used in communication between the base station and the UE based on the UE information; and
configuring uplink resources during each measurement gap of the one or more measurement gaps to enable the UE to perform uplink communication during the one or more measurement gaps using the uplink resources.
5. The method of claim 4 , wherein the high priority application includes a low-latency application or a mission-critical application.
6. The method of claim 1 , further comprising:
transmitting a downlink control channel signal during a measurement gap;
monitoring for a measurement completion indication in response to the downlink control channel signal; and
determining that the UE has completed a measurement before the measurement gap expires when the measurement completion indication is received.
7. The method of claim 6 , further comprising:
allocating at least one of an uplink grant or a resource for a reference signal transmission to receive the measurement completion indication from the UE.
8. The method of claim 1 , wherein the UE information includes a requested measurement gap pattern,
wherein the one or more measurement gaps are configured based on the requested measurement gap pattern.
9. The method of claim 1 , wherein the configuring the one or more parameters of the one or more measurement gaps comprises:
setting a time interval between each of the one or more measurement gaps.
10. A base station for wireless communication, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
obtain user equipment (UE) information of a UE;
configure one or more parameters of one or more measurement gaps based on the UE information;
set a measurement gap duration of at least one of the one or more measurement gaps to a short duration when the UE information indicates that the UE is measuring a current serving cell;
set the measurement gap duration of the at least one of the one or more measurement gaps to a long duration when the UE information indicates that the UE is attempting to detect another cell
and
transmit, to the UE, a measurement request including measurement gap information on the one or more measurement gaps.
11. The base station of claim 10 , wherein as part configuring the one or more parameters of the one or more measurement gaps, the at least one processor is further configured to:
determine a mobility state of the UE based on the UE information, the UE information including at least one of uplink reference signal, or feedback information from the UE;
set a measurement gap duration of at least one of the one or more measurement gaps to a short duration and a frequency of occurrence of the at least one of the one or more measurement gaps to be high when the mobility state of the UE indicates that the UE is stationary; and
set the measurement gap duration of the at least one of the one or more measurement gaps to a long duration and a frequency of occurrence of the at least one of the one or more measurement gaps to be high when the mobility state indicates that the UE is mobile.
12. The base station of claim 10 , wherein as part configuring the one or more parameters of the one or more measurement gaps, the at least one processor is further configured to:
determine that a high priority application is used in communication between the base station and the UE based on the UE information; and
configure uplink resources during each measurement gap of the one or more measurement gaps to enable the UE to perform uplink communication during the one or more measurement gaps using the uplink resources.
13. The base station of claim 10 , wherein the at least one processor is further configured to:
transmit a downlink control channel signal during a measurement gap;
