DISTRIBUTED RESOURCE UNIT TRANSMISSION
This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.
DYNAMIC POWER AGGREGATION
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use dynamic power aggregation techniques to perform instantaneous transmit power adjustments in an uplink carrier aggregation configuration. For example, the UE may dynamically adjust the instantaneous transmit power with network assistance. In some cases, the base station may configure a set of power aggregation parameters to control the instantaneous transmit power behavior of the UE. The UE may adjust the instantaneous transmit power in accordance with the power aggregation parameters. In some other cases, the base station may configure the UE to report one or more parameters. Based on the report, the base station may determine a power aggregation configuration for the UE in a time interval. In some other cases, the UE may be configured to scale the instantaneous transmit power for individual component carriers in the carrier aggregation configuration.
Uplink power control prioritization in dual connectivity
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing dynamic power control with minimal complexity in a dual connectivity mode. In particular, a user equipment (UE) may determine the reserved power (or maximum available power) for uplink transmissions on one or more cells in one cell group to a base station based on the total power available to the UE and the minimum reserved power for uplink transmissions on one or more cells in another cell group. Once the UE determines the reserved power for conflicting uplink transmissions on one or more cells in a cell group, the UE may allocate the reserved power to each uplink transmission on the one or more cells in the cell group (e.g., based on a priority of each of the uplink transmissions).
Almost blank subframe in carrier aggregation
Aspects are described for use in wireless communications. A subframe allocation bitmap may indicate multiple subframes. The indicated subframes may correspond to Almost Blank Subframes. Measurement subframe allocation bitmaps may indicate measurement subframes. A first measurement subframe allocation bitmap may exclude subframes indicated by the subframe allocation bitmap. A second measurement subframe allocation bitmap may exclude the measurement subframes indicated by of the first measurement subframe allocation bitmap.
Method for transmitting uplink control information
Embodiments of the present disclosure provide a method for transmitting uplink control information. The method includes: a User Equipment (UE) receives Uplink Control Information UCI configuration information, wherein the UCI configuration information includes information for determining a periodicity, an offset and a Physical Uplink Control Channel PUCCH for Periodic-Channel State Information P-CSI to be report in one subframe and configuration information for transmission of Hybrid Automatic Retransmission reQuest-Acknowledgement HARQ-ACK; processes one or more kinds of UCI in the subframe, and transmits the UCI on resources using a PUCCH format. According to the method of the present disclosure, the transmit power for transmitting the UCI on the channel using the PUCCH format is optimized. During the transmission of the P-CSI, the PUCCH resource most preferable for the transmission of the P-CSI is determined. The uplink resource utilization ratio is increased.
Indication of multiple power classes
A wireless device that indicates multiple power classes to a network node, a network node that uses the indicated multiple power classes, and related methods of operation for the wireless device and the network node are disclosed. The disclosed embodiments aim at an increase flexibility in setting different power classes in different communication scenarios while reducing signalling overhead for capability signalling for the wireless device.
