Abstract: Methods and systems are provided for dynamically adjusting broadcast beam patterns of a wavefront emitted by an antenna array based on the types of devices communicatively coupled to the base station associated with the antenna array.

Depending on the timing information, the radio device (10) may decide whether to switch to another carrier frequency or to wait on a currently used carrier frequency to receive the access information table.

Abstract: Certain aspects of the disclosure relate to techniques and apparatus for improving random access for SRS switching in a wireless network. Prior to transmitting a SRS, a UE may interrupt communication on a first carrier to switch from the first carrier to a second carrier to transmit a PRACH. To reduce interruption to the first carrier, the UE may use the beginning symbol(s) of a UpPTS on the second carrier to transmit the PRACH. In addition, to reduce interruption to the first carrier, the UE may monitor for another PDCCH order before transmitting another PRACH. Further, aspects of the present disclosure provide techniques and apparatus for jointly triggering SRS transmissions and performing power control for SRS transmissions. A BS may trigger SRS transmissions from multiple UEs, trigger SRS transmissions from multiple carriers from the same UE at the same time and/or perform power control separately for each carrier.

A frame that includes an indication of the amount of resources is generated and transmitted to at least one of the first BSS and the second BSS.

Abstract: A reconfigurable triplexer that can support more frequency bands than a traditional triplexer is disclosed. For example, the reconfigurable triplexer can handle frequencies of several hundred megahertz up to 10 gigahertz. Further, certain implementations of the reconfigurable multiplexer can reduce or eliminate frequency dead zones that exist with traditional multiplexers. The reconfigurable triplexer includes a multi-stage filter bank capable of supporting a number of frequency bands and a bypass circuit that enables the triplexer to support a variety of sets of frequencies. For instance, unlike traditional triplexers, the reconfigurable triplexer can support both frequency bands with relatively narrow spacing and frequency bands with relatively wide spacing. Further, the inclusion of the bypass circuit enables the reduction or elimination of dead zones between supported frequencies.
