摘要： Method, apparatus, and computer program product for a user equipment in a wireless communications system to receive configuration information that has one or more TCI-states. With this configuration information, the user equipment can then determine inactivity on TCI-states. Based on that determination, the user equipment enables either a discontinuous monitoring or a cessation of monitoring on those TCI-states. Each TCI-state corresponds to a radio beam and also corresponds to an antenna panel. By reducing such monitoring, the use equipment can deactivate antenna panels corresponding to the TCI-states. The determination can be done through the use of a timer with various time thresholds based on the TCI-state. The activity being transmitted on those beam can be scheduling received by the user equipment from a network element such as a base station. The TCI-states can also be grouped and the functionality of the invention dealt with on a group basis.

摘要： Various communication systems may benefit from improved performance. For example, communication systems may benefit from a multi-functional reference signal that allows for the harmonization of different reference signal patterns. A method, in certain embodiments, may include constructing at a base station a reference signal including a plurality of reference signal patterns. The plurality of reference signal patterns can include at least one of a default reference signal pattern or a multi-functional signal pattern for at least one of uplink or downlink. The plurality of reference signal patterns can include at least one of partially overlapping or non-overlapping resource elements. In addition, the plurality of reference signal patterns are constructed dynamically for a specific user or group of users. The method may also include sending the reference signal from the base station to a user equipment.

摘要： When a time domain collision between Tracking Reference Signal (TRS) symbols and downlink shared data channel symbols is detected, the TRS symbols may be multiplexed with the downlink shared data channel symbols from multiple Transmission Reception Points (TRPs) not sharing quasi co-location (QCL) parameters with each other. If a time domain collision between TRS symbols and dynamically or semi-static (e.g., persistent) downlink shared data channel transmissions is detected, transmission and/or reception of the TRS and/or the downlink shared data channel may be adjusted.

摘要： According to an aspect, a method for configuring user devices to monitor a downlink control channel includes receiving, by a user device from a base station in a wireless communication system, a signaling message identifying beam information, and determining, by the user device, whether the beam information is associated with at least one adaptive configuration parameter for monitoring a downlink control channel using parameter mapping information, where the parameter mapping information associates adaptive configuration parameters with one or more of a plurality of beam information. The method includes applying the at least one adaptive configuration parameter to configure the user device to monitor a downlink control channel in response to the beam information being determined as associated with the at least one adaptive configuration parameter.
