  • Patent number: 10306593
    Abstract: In wireless communications systems, a client terminal performs cell search procedure to find a suitable cell and camp on it to receive service from the network. In 3GPP LTE wireless communication system, the initial cell search involves the decoding of the Physical Broadcast Channel (PBCH) which may take a long time to decode which affects the time it takes to camp on an appropriate cell. One of the reasons for this is that conventional methods perform PBCH decoding sequentially to find a suitable cell. A method and apparatus are disclosed that perform the PBCH decoding in parallel for multiple cells. This method enables the client terminal to camp on a cell and receive service faster than conventional methods.

  • Patent number: 10271321
    Abstract: The 3GPP LTE wireless communication system employs dynamic scheduling and assignment of resources using the Physical Downlink Control Channel (PDCCH) to support low latency requirements for many applications. To keep the payload overhead low on the control messages, the dynamic scheduling and assignment messages over the PDCCH need to be decoded by the User Equipment (UE) by searching a number of possible PDCCH candidates in a given control region of the 3GPP LTE wireless communication system. This is often referred to as blind decoding of PDCCH. The high number of blind decoding attempts may lead to increased power consumption in a UE. A method and apparatus are disclosed that enable a UE to reduce the total number of decoding attempts without missing any PDCCH candidates that may be addressed to the UE which in turn may reduce the power consumption and may reduce the probability of false DCI detection.

  • Patent number: 10212679
    Abstract: The propagation channel in a wireless communication system may be characterized as a multipath fading model wherein the multiple delayed and attenuated versions of the transmitted signal are received. In the receiver's processing chain, the impairments introduced by this propagation channel may be equalized using the channel estimates. The channel estimation is mainly performed using the known reference signals by conventional methods. The estimation of delay spread profile may be crucial for high performance channel estimation. The conventional methods may be appropriate for high operating channel bandwidths. In the case of low channel bandwidth, limited number of reference signals may be available which may not be adequate for accurate delay spread estimation. A method and apparatus are disclosed that improve the delay spread estimation for low channel bandwidth scenarios.

  • Patent number: 10212633
    Abstract: In cellular communication systems, the success rate for incoming calls for a client terminal in idle mode is related to the successful reception of paging messages. The instances for paging message transmission, known as paging occasions, may be based on a client terminal's unique identity. The network transmits a paging message addressed to a specific client terminal in its specific paging occasion. In addition to the reception of paging messages, a client terminal may be required to search and monitor neighbor cells for cell reselection and handoffs. A method and apparatus are disclosed that improve the cell reselection by using the known a priori information to categorize the neighbor cells, to categorize the cell reselection types, and to perform cell reselection to an appropriate neighbor cell at the opportune time such that a paging message reception may be neither missed nor delayed during the cell reselection.

  • Patent number: 10206124
    Abstract: Many applications used in communication systems involve bidirectional data transfer. In bidirectional data transfer applications, a client terminal has to turn on its hardware components such as transmitter at the time of transmitting the data and the receiver at the time of receiving the data. When the transmission and reception of data happens at different time instances, the client terminal has to turn on and off the transmitter, the receiver and other modules at separate time instances. This may lead to increased power consumption. A method and apparatus are disclosed for the modem in a client terminal that bring the transmission and the reception instances close to each other or overlap with each other when performing bidirectional communication. This may reduce the rate at which the client terminal has to turn on and off its transmitter, receiver and other modules which may in turn reduce its power consumption.
