  • Patent number: 10200951
    Abstract: Certain aspects of the present disclosure relate to techniques for processing (e.g., such as tasks for wireless communications and/or multimedia). According to certain aspects, a method for low power low latency data exchange generally includes providing timing information from a first processing entity to a second processing entity indicating when the second processing entity is to next process a message exchange between the first and second entities using a shared memory space, taking action to exit a low power state, based on the timing information, to access the shared memory space to process the message exchange, and entering the low power state after processing the message exchange.

  • Patent number: 10187874
    Abstract: The present invention relates to a method and an apparatus for a user equipment receiving MBMS service processing a semi-permanent scheduling from an MBSFN subframe. A method for a user equipment receiving the multimedia broadcast multicast service (MBMS) processing a downlink scheduling in a mobile communication system of the present invention comprises: a detection step of detecting the occurrence of the downlink scheduling in a random transmission time interval; a decision step of deciding whether to process the downlink scheduling, depending on whether the user equipment is set to a transmission mode 9 or whether the transmission time interval belongs to a multimedia broadcast multicast service single frequency network (MBSFN) subframe; and a processing step of processing or disregarding the downlink scheduling based on the result of the decision.

  • Patent number: 10154462
    Abstract: The present disclosure relates to a CDMA communication node arrangement comprising at least two spatially separated antenna units, at least one radio unit and at least one control unit. Each antenna unit has at least one corresponding coverage area and is connected to the central unit. The control unit is arranged to alter transmitting properties of at least a first antenna unit, to a user terminal, such that more or less power is transmitted by the first antenna unit in a dedicated channel. The control unit is arranged to monitor received inner power control loop commands when at least a second antenna unit is communicating with the user terminal, and to determine whether said first antenna unit should start or stop communicating with the user terminal, or continue as before, based on how the inner power control loop commands respond. The present disclosure also relates to a corresponding method.
