AMPLIFIER ADJUSTMENT TO REDUCE LATENCY
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust an amplifier of the UE to a highest gain state after a downlink period and before an uplink period. Additionally, the UE may adjust the amplifier of the UE to a lower gain state after the uplink period and before a subsequent downlink period. Numerous other aspects are described.
Methods and apparatus for multi-carrier communication systems with adaptive transmission and feedback
An arrangement is disclosed where in a multi-carrier communication system, the modulation scheme, coding attributes, training pilots, and signal power may be adjusted to adapt to channel conditions in order to maximize the overall system capacity and spectral efficiency without wasting radio resources or compromising error probability performance, etc.
Reliability detection of channel quality indicator (CQI) and application to outer loop power control
A method for performing outer loop power control in wireless communications includes initializing a time interval clock to count down a predetermined time interval; receiving and decoding a channel quality indicator (CQI) message; computing a decision metric value for each symbol in the decoded CQI message; determining whether the CQI message is erroneous; counting a number of erroneous CQI messages; and signaling a wireless/transmit receive unit to adjust an uplink transmission power on a condition that the time interval clock has expired and the number of erroneous CQI messages exceeds a threshold.
Inter-modulation distortion reduction in multi-mode wireless communication terminal
A multimode wireless communication terminal that communicates using a first radio access technology (RAT) and a second RAT determines whether the first and second RATs are in an active state, and modifies a maximum transmit power limit of the first RAT based on a voice codec rate of a voice transmission on the second RAT when the first RAT and the second RAT are in the active state concurrently, wherein the second RAT is conducting the voice transmission in the active state. In an alternative embodiment, the limit is modified based on a transmit power status of the second RAT or on a transmission type of the first RAT.
CONTROLLED SPATIAL REUSE IN A WLAN
An interface circuit in an electronic device may receive, from an access point associated with the electronic device, a frame with management information that enables the electronic device to use a spatial-reuse technique, where the electronic device, through the spatial-reuse technique, adjusts a transmit power and a channel-availability sensing threshold. Moreover, the management information may specify parameters for the spatial-reuse technique. Then, the electronic device may transmit, using the spatial-reuse technique, one or more frames to the access point based on the parameters. Furthermore, the electronic device may transmit, to the access point, feedback information that indicates communication performance during the communication between the electronic device and the access point. For example, the feedback information may include a retry rate and, more generally, communication-performance information. This feedback information may be used by the access point to modify the parameters.
WIRELESS ACCESS POINT MANAGING APPARATUS
A wireless access point managing apparatus for achieving power savings by turning off access points that are not providing the high signal quality. The wireless access point determines whether a first signal quality level is at or above a threshold level, and if so, sends a power-up signal to a second access point, and determines whether the first signal quality level is higher or lower than a second quality level, i.e., the level from the second access point, transfers a streaming session to the second access point if the first signal quality level is lower than second signal quality level. If the first signal quality level is higher than the second signal quality level, the apparatus sends a power-down signal to the second access point.
Throughput characterization
In embodiments, apparatuses, methods, and storage media may be described for characterizing throughput of a user equipment (UE) for transmission this transmitted using a modulation and coding scheme (MCS). Specifically, in embodiments throughput of the UE may be characterized using interpolation of UE throughput for one or more discrete signal strength values.
Method and apparatus for controlling channel occupancy based on energy-level-coded quality of service indicia
An improved method for controlling how long a device will occupy a wireless channel, based on consideration of QoS class of communication on the channel. With respect to a communication that the device detects on the channel, the device could determine QoS class by detecting a sequence of energy levels in association with the detected communication, the sequence of energy levels indicating the QoS class. The disclosed method could be applied by a cellular base station to control how long the base station will provide cellular service on the channel, where the channel is also used for other communications such as WiFi communications for instance.
POWER CONTROL FOR SIDELINK FEEDBACK TRANSMISSIONS
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for sidelink feedback power control. The UE may transmit a sidelink feedback transmission, in accordance with the configuration, using a transmit power that is based at least in part on at least one of: a quantity of resource blocks (RBs) associated with the sidelink feedback transmission, a quantity of symbols associated with the sidelink feedback transmission, a sidelink pathloss value, or a size of the sidelink feedback transmission. Numerous other aspects are provided.
