Abstract: A wireless device receives at least one message from a base station. The at least one message comprises: configuration parameters of cells; a transmit power control (TPC) radio network temporary identifier (RNTI); a primary TPC index for the primary PUCCH; and a secondary TPC index for the secondary PUCCH. The configuration parameters of cells comprise: a primary cell with a primary physical uplink control channel (PUCCH); and a secondary cell with a secondary PUCCH. A common search space is searched for a downlink control information (DCI) associated with the TPC RNTI. The DCI comprises an array of TPC commands. The secondary TPC index identifies a TPC command in the array. The uplink signal transmission power of the secondary PUCCH is adjusted based on the TPC command.

Abstract: Methods and apparatuses are described herein for determining a transmit power based on clear channel assessment (CCA) thresholds. A station (STA) associated with a first Basic Service Set (BSS) may receive, from an access point (AP) associated with the first BSS, a clear channel assessment (CCA) value for a group of STAs associated with a second BSS. The CCA value may indicate a minimum CCA threshold for a packet received from the second BSS. The STA may then determine, based on the CCA value, a STA specific CCA parameter and a target CCA parameter. The target CCA parameter may be greater than or equal to the STA specific CCA parameter. Based on the STA specific CCA parameter and the target CCA parameter, the STA may determine a target transmit power control (TPC) parameter of the STA, wherein the sum of target TPC parameter and target CCA parameter is constant.

Abstract: A jamming or MAS system is provided having multiple transmit antennas for transmitting respective transmit signals with spatial diversity to reduce multipath fading. The jamming or MAS communication system communicates with at least one receiver for receiving the transmit signals with no additional processing required at the receiver. In some embodiments, the jamming or MAS communication system includes an associated receiver for receiving and analyzing various signals. The jamming or MAS communication system in the present invention is able to help reduce the effects of multipath fading without modifications to the receiver. Prior art attempts to reduce the effects of multipath fading require some form of additional processing at the receiver. The invention is particularly useful when deployed in a Managed Access Service (MAS) system or a jamming system. In particular, such a system can be used in a facility (such as a prison, school, government building, etc) to prevent cellphone usage.

Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.
