Abstract: A system and method dynamically schedule wireless transmissions without collision. A master transmitter periodically transmits a time mark during a first predefined time slot of a plurality of consecutive time slots that form a transmission block. Multiple consecutive transmission blocks form a frame. An announcement transmission from a wireless transmitting device is received via at least one receiver during a second predefined time slot of the plurality of time slots. An allocator allocates, at least partly based upon the received announcement transmission, a third time slot of the plurality of time slots to the wireless transmitting device. A time slot reservation area of at least one subsequently transmitted time mark includes indication of the allocation of the third time slot to the wireless transmitting device. The wireless transmitting device receives the subsequently transmitted time mark and transmits only during the third time slot of subsequent frames.

Abstract: Blocking of undesirable voice over internet protocol (VOIP) communications is disclosed. A communication screening service initiates operations to block a threat posed by a VOIP communication upon receiving the communication from a gateway server. The communication may include an audio/video conversation and/or an audio/video conference. Next, metadata and content of the communication is analyzed to detect a threat, such as a scamming scheme and/or a phishing scheme, from a sender of the communication. A rejection of the communication is generated to disrupt the threat associated with the communication. The rejection is transmitted to the gateway server to prompt the gateway server to block the communication.

Abstract: Apparatus and methods are provided to reorder PDCP SDUs. In one novel aspect, a timer-based PDCP reordering process is triggered upon detecting a PDCP gap existing condition, which indicates an SN gap between the PDCP SDUs of two parallel RLC entities larger than zero. The PDCP gap-closing condition is detected when the last-delivered SDU COUNT number plus one equals to the next-expected SDU COUNT number. In one embodiment, all the stored PDCP SDUs with consecutive COUNT numbers starting from the received SDU COUNT number are delivered upon detecting the PDCP gap-closing condition. In another novel aspect, a reordering timer is started upon detecting the PDCP gap condition. In one embodiment, the expiration of the reordering timer triggers the delivery of SDUs to upper layers. In one embodiment, the UE is configured with dual connectivity and the reordering SDU COUNT numbers and the reordering timers are associated with different connectivity configured.

Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE) may signal a band-specific measurement gap indication based on the capability of a set of receivers to measure target frequency bands while monitoring a set of component carriers (CCs). The UE may receive a measurement gap configuration for a first component carrier (CC) associated with measuring the target frequency bands accounting for the band-specific measurement gap indication.

In some examples the measurement gap configuration message includes configuration options and the UE may select the measurement gap configuration for the first CC from the set of available options.

Abstract: A wireless communication network controls data services that are delivered over a wireless access point. The wireless access point broadcasts service identifiers for the data services to user communication devices. The user communication devices and the wireless access point exchange the user data for the data services. The wireless access point and a network gateway exchange the user data for the data services. The network gateway processes the user data to determine if one of the data services falls below a Quality-of-Service (QoS) threshold. If one of the data services falls below its QoS threshold, then the network gateway transfers an instruction to stop wirelessly broadcasting the service identifier for the data service. The wireless access point receives the instruction and stops its wireless broadcast of the service identifier for the data service.
