Transmit Power Priority Based on Cell Types in Wireless Devices
A wireless device may determine a calculated total transmit power for a plurality of signals. The plurality of signals may include a first uplink signal and a second uplink signal. The first uplink signal may be configured for transmission, during a time interval, via one or more first cells of a first cell type. The second uplink signal may be configured for transmission, during the time interval, via one or more second cells of a second cell type. The wireless device may drop a transmission of the first uplink signal or scale a transmission power of the first uplink signal, based on a transmit power priority of the first uplink signal and in response to the calculated total transmit power exceeding a first value. The transmit power priority may be based on a cell type of the one or more first cells.

SYSTEMS AND METHODS FOR NEW-RADIO-AWARE LTE SCHEDULING
New Radio (NR)-aware LTE scheduling is provided. An access station for a radio access network includes a first scheduling function. The first scheduling function identifies a User Equipment (UE) device that has a first active wireless connection and a second active wireless connection to the radio access network. The first scheduling function determines that expanded coverage is need for an uplink transmission for the second active wireless connection and obtains uplink scheduling information for the second active wireless connection. The first scheduling function adjusts uplink scheduling for the first active wireless connection such that power sharing is prioritized for uplink time intervals of the second active wireless connection over overlapping uplink time intervals of the first active wireless connection.
Techniques for power control using carrier aggregation in wireless communications
Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.
Energy saving method and apparatus, and computer-readable storage medium
A centralized controller determines n radio remote units (RRUs) in m RRUs, where a sum of first downlink reference signal received powers (RSRPs) of a same terminal, corresponding to the n RRUs, is greater than or equal to a first preset value, and a first downlink RSRP of one terminal corresponding to one is a received power that is estimated by the centralized controller, that is measured by the terminal, and that is of a reference signal (RS) from the RRU at a corresponding first RS transmit power. The centralized controller turns off an RRU that is in the m RRUs and that is different from the n RRUs, boosts a second RS transmit power corresponding to each of the n RRUs to a corresponding first RS transmit power, and enables each of the n RRUs to send an RS at the corresponding first RS transmit power.

System and Method for Phase Noise Reduction in Very High Frequency Spectrum
Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.
Uplink transmission techniques for exposure limited transmissions
Methods, systems, and devices for wireless communications are described for handling uplink grants that have associated uplink transmission that may exceed exposure limits. Exposure limits may be based on maximum permissible exposure (MPE) limits of millimeter wave transmissions and may be determined at a user equipment (UE) and provided to a base station. If the UE receives an uplink grant for a transmission in which an associated uplink transmission would exceed the exposure limits, the UE may drop the uplink transmission prior to forming a transport block, transmit control signaling to the base station to indicate the exposure limits at the UE, or combinations thereof.
Accommodating simultaneous transmissions in a wireless channel
Systems and methods are disclosed for improving communication efficiency in environments featuring both 802.11ax devices and legacy devices. Although 802.11ax introduces the ability for multiple devices to transmit simultaneously over a wireless channel, this feature is not used to its full potential because legacy devices transmit using turn-based communication (waiting for the channel to free up before transmitting). To create the illusion that the channel is free, in one method, an 802.11ax access point lowers the power for 802.11ax transmissions in a portion of a wireless channel being utilized by the legacy device. In another method, the 802.11ax access point blanks the portion of the wireless channel altogether (i.e., does not schedule transmissions over the portion). As a result of these methods, signal interference is reduced, and legacy devices do not halt transmissions to follow turn-based communication.
