Abstract
Systems, methods, apparatuses, and computer program products for reference signal adaptation based on incoming user mobility information are provided. One method includes receiving, by a target base station, a request to begin transmitting reference signals for mobility measurements. The request may be received from a source base station serving a user equipment. In addition, the request may be received when a handover of the user equipment is impending.
Claims19
A method, comprising:
- receiving, by a target base station, a request to begin transmitting reference signals for mobility measurements, the request being received from a source base station serving a user equipment;
- and
- in response to the request, deciding whether or not to configure reference signal density and/or reference signal periodicity and transmit the reference signals for mobility measurements to the user equipment,
- wherein the receiving of the request further comprises receiving, by the target base station, at least one of reference signal density or reference signal periodicity information from the source base station.
1 more element
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to
- receive a request to begin transmitting reference signals for mobility measurements, the request being received from a source base station serving a user equipment;
- and
- in response to the request, decide whether or not to configure reference signal density and/or reference signal periodicity and transmit the reference signals for mobility measurements to the user equipment,
- wherein the request further comprises at least one of reference signal density or reference signal periodicity information from the source base station.
5 more elements
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to
- determine that a target base station should be informed about a need for reference signals for mobility measurements;
- and
- send a request to the target base station to begin transmitting reference signals for mobility measurements to a user equipment;
- wherein the apparatus comprises a source base station serving the user equipment,
- wherein the request further comprises at least one of reference signal density or reference signal periodicity information from the source base station.
