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. A signal is received in a modem. Signal elements at reference signal (RS) locations are extracted from the received signal. The signal elements at the RS locations are descrambled. Virtual reference signal (VRS) elements are formed using the descrambled signal elements. The VRS elements have smaller noise variances than original RS elements in corresponding locations of the received signal. The RSRP is estimated from the VRS elements.
FACTORS AFFECTING MEASUREMENT PERIOD FORMULATION FOR POSITIONING
Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a request location information message from the network entity, the request location information message including one or more start measurement time parameters indicating a start time of a measurement period during which the UE is expected to perform one or more positioning measurements, and performs the one or more positioning measurements of one or more positioning reference signal (PRS) resources on a first positioning frequency layer during the measurement period, wherein a start of the measurement period is based on the one or more PRS resources, a reception time, and the one or more start measurement time parameters.
Physical layer shielding of wireless communications
Presented herein are techniques to shield transmissions from being received and the information contained in them recovered by unwanted devices. Multi-user multiple-input multiple-output (MU-MIMO) techniques are employed, and in particular the spatial dimension aspects of those techniques. Shield nodes are controlled to transmit in a way to obscure the downlink streams transmitted by a wireless access point that are intended for a particular client device to anything outside of the shielded area, and also to obscure uplink streams from one or more client devices to the wireless access point to anything outside of the shielded area but allowing the uplink streams to be well received by the wireless access point.

INTELLIGENT SELECTION OF PHYSICAL LAYER TRANSMISSION TYPES IN 802.11AX BASED WI-FI NETWORKS
A transmission type is determined for a specific station on a Wi-Fi network. A transmission type of OFDMA is selected responsive to the mobility value for the specific station meeting a mobility threshold. A transmission type of MU-MIMO is selected responsive to the similarity value for the specific station meeting a similarity threshold. A transmission type of SU-MIMO is selected responsive to the specific station not meeting the similarity threshold. The network interface transmits data packets to stations using OFDMA, SU-MIMO or MU-MIMO as selected

Measurement Period for Beam Reporting
In NR, a gNB utilizes multiple antennas and beam forming techniques for downlink transmissions to UEs. Described herein are methods and apparatus by which a UE measures the quality of multiple directional beams received from a gNB.
DETECTING STATIC CHANNELS
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, based at least in part on two or more measurements on a channel taken at different points in time, that the channel is classified as static. The wireless communication device may perform at least one optimization based at least in part on determining that the channel is classified as static. For example, the at least one optimization may include modifying a channel state feedback procedure, reducing a periodicity associated with a measurement gap, modifying a filtering associated with measurements of the channel, reducing a threshold associated with beam switching, and/or refraining from performing at least one filtering at a radio frequency receiver of the wireless communication device. Numerous other aspects are described.
SYSTEMS AND METHODS FOR MODIFYING PARAMETERS OF A WIRELESS NETWORK BASED ON GRANULAR ENERGY EFFICIENCY METRICS
A system described herein may receive traffic throughput metrics and energy consumption metrics associated with one or more elements of a wireless network, and compute granular (e.g., per-network slice, per-network element, per-protocol, per-layer, etc.) measures of energy efficiency associated with the one or more one or more elements. The system may determine network parameter modifications based on the granular measures of energy efficiency, and/or provide such measures of energy efficiency to the one or more network elements, which may grant access to UEs 109 based on the granular measures of energy efficiency. The one or more network elements may make network parameter modifications based on the granular measures of energy efficiency, such as activating “sleep” or “suspend” modes, and/or otherwise performing energy saving techniques.
