Method and apparatus for providing enhanced reference signal received power estimation
A method and an apparatus for providing reference signal received power (RSRP) are disclosed herein. According to one embodiment, a signal is received in a modem. Signal elements at reference signal (RS) locations are extracted from the received signal. The signal elements are descrambled to remove a RS sequence. A linear average of the descrambled signal elements is performed to form virtual reference signal (VRS) elements. The RSRP is estimated from the VRS elements.
INTER-CELL L1-RSRP REPORTING
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a layer one reference signal received power (L1-RSRP) measurement report to include an indication of L1-RSRP measurements associated with one or more synchronization signal bocks (SSBs) included in an SSB set, wherein the SSB set is identified, from a plurality of SSB sets, in the L1-RSRP measurement report by an SSB set indicator, and wherein the one or more SSBs are identified in the L1-RSRP measurement report by respective SSB indexes that index into the SSB set. The UE may transmit the L1-RSRP measurement report. Numerous other aspects are provided.

METHODS AND APPARATUSES FOR DYNAMIC ANTENNA ARRAY RECONFIGURATION AND SIGNALING IN MILLIMETER WAVE BANDS
The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Apparatus and method for feeding back channel quality information and scheduling apparatus and method using the same in a wireless communication system
An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.
METHOD AND APPARATUS FOR MITIGATING SIGNAL INTERFERENCE IN A FEEDBACK SYSTEM
A system that incorporates the subject disclosure may include, for example, a process that includes adjusting a filter in electrical communication between an input terminal and a demodulator. The filter is applied to an information bearing signal, e.g., to mitigate interference, received at the input terminal, resulting in a filtered signal. An error signal is received, indicative of errors detected within information obtained by demodulation of a modulated carrier of the filtered signal. A modified filter state is determined in response to the error signal and the filter is adjusted according to the modified filter state, e.g., to improve mitigation of the interference. Other embodiments are disclosed.
