Embodiment Construction

[0055] In beam-based systems, the processing at the wireless device side increases (especially as the number of beams per network node increases). The amount of signaling may also increase, since the presence of multiple transitions from one home beam to a different beam may need to be reflected in the signaling. If the measurements per beam are not filtered, the number of reports is also high due to fluctuations in signal strength. In some cases, this is handled by filtering to reduce the impact of these changes. However, given the large number of possible beams, one filter per beam would significantly increase processing at the wireless device.

[0056] In NR, the possibility of active-mode MRS using beamforming will bring advantages in steering the wireless device to the correct beam during handover. However, the possibility of active-mode MRS using beamforming also creates challenges for wireless device measurement and reporting. One possible way to address these challe...

Abstract

A method (1100) in a wireless device (110) comprising obtaining (1104) a configuration of measurement management associated with multiple signal based cell definition, the configuration defining a first cell (125A) based on a first set of signals. The method includes configuring (1108) measurement management associated with the multiple signal based cell definition according to the obtained configuration. The method includes performing (1112) one or more measurements on a first set of signals defining a first cell.

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more particularly to flexible definition of cells based on signal sets. Background technique [0002] In traditional networks, the communication between multiple network nodes (e.g., base stations) in the radio access network is implemented based on wireless device (e.g., user equipment (UE)) measurements of reference signals transmitted from the serving base station and neighboring base stations. mobility. Measurement reports can be sent to the serving base station periodically, or based on a measurement report triggering event. [0003] For Long Term Evolution (LTE), in the 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 36.331v14.0.0 (2016-09) "Technical Specification, 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; The measurement report trigger event is specified in Evolved Universal Terrestrial Radio Access (E-...
