Methods, systems, and devices for power control for random access protocols in mobile communication technology are described. An exemplary method for wireless communication includes broadcasting, by a network node serving a cell, an indication of a transmit power level that is specific to the cell, wherein the indication is for use by a wireless device operating in the cell for a two-step random access procedure. Another exemplary method for wireless communication includes receiving, by a wireless device operating in a cell served by a network node, an indication of a transmit power level that is specific to the cell for use in a two-step random access procedure, and transmitting, at the transmit power level, a first message of the two-step random access procedure.

Various aspects pertain to a method for a UE to unilaterally initiate a request to a serving base station to change or enhance beam coverage at the UE. The UE may measure one or more characteristics of a directional beam transmitted by the base station and determines whether channel reliability for the beam should be improved. If channel reliability is below a threshold, then the UE may transmit a request to the base station seeking to adjust coverage of the beam (such as coverage enhancements). Such request may seek to adjust one or more transmit or receive parameters associated with the beam or channels transmitted therein. The UE may switch to using a pre-defined set of coverage enhancement parameters or procedures either automatically after transmitting the request or upon receipt of a grant by the base station.

Aspects are described for use in wireless communications. Nodes may provide wireless access to wireless devices in different coverage areas. The nodes may transmit messages having time interval allocation bitmaps that indicate reduced transmission power time intervals. The reduced transmission power time intervals may be different for different nodes.

[Object] To achieve both prevention of harmful interference and promptness of power allocation under conditions in which multiple secondary systems may be managed. [Solution] Provided is a communication control apparatus including: a calculation unit configured to calculate a transmit power to be allocated, including a nominal transmit power and a margin for interference avoidance, for one or more secondary systems that secondarily use frequency channels protected for a primary system; and a determination unit configured to determine a variation in a number of secondary systems, and cause the calculation unit to adjust the margin for interference avoidance on a basis of the determined variation.

Systems and methods to accomplish a power control system in a MANET are described herein. To reduce detectability of the MANET, the controller 310 can reduce transmit power at individual links while operating the link's modulation and coding data rate and data queue backlog at levels that are sufficient to meet the user's offered load.

Methods and devices for offloading and/or aggregation of resources to coordinate uplink transmissions when interacting with different schedulers are disclosed herein. A method in a WTRU incudes functionality for coordinating with a different scheduler for each eNB associated with the WTRU's configuration. Disclosed methods include autonomous WTRU grand selection and power scaling, and dynamic prioritization of transmission and power scaling priority.

Dynamic data rate selection in wireless networks is described. The includes sending, by a wireless controller to a base station, an access point power-data rate table. The base station updates a base station power-data rate table with the access point power-data rate table based on checking defined thresholds, confirms the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table, reverts to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct, and sends to the wireless controller one of the updated base station power-data rate table or the previous base station power-data rate table. The wireless controller updates the access point power-data rate table and sends the updated access point power-data rate table to an access point.
