  • Patent number: 9756680
    Abstract: Disclosed is a method and apparatus for generating a PDU and a base station thereof. The method for generating a PDU includes: segmenting an input SDU into at least one segmentation in such a manner that the at least one segmentation is distributed in at least one PDU; and setting an offset field and at least one length indicator field in a header of each PDU, wherein the offset field indicates an offset of a first segmentation of a first new SDU appearing in the PDU, and the length indicator field indicates the end of the new SDU or the segmentation of the new to SDU in the PDU. With the present invention, since a single SDU is indicated only using one LI even if it is segmented into a plurality of segmentations, and the LI indicates the end of SDU in one PDU, it is ensured that an eNB in the SFN can recover packets in case of multiple packets loss while avoiding de-synchronization during the contents transmission.

  • Patent number: 9750050
    Abstract: Access priority for wireless devices located in an area in which radiofrequency (RF) coverage areas of a first wireless access point and a second wireless access point overlap is controlled by coordinating operation of the first wireless access point and the second wireless access point. The wireless devices access a common RF channel via a collision sense multiple access/collision avoidance mechanism. The probability of accessing the RF channel may be varied by adjusting the length of interframe spacings and the length of contention windows. The length of the interframe spacings and the length of the contention windows associated with the first access point and associated with the second access point are configured such that the probability of wireless devices associated with the first wireless access point accessing the RF channel is greater than the probability of wireless devices associated with the second wireless access point accessing the RF channel.

  • Patent number: 9730245
    Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). In some examples, a base station may allocate, to a UE, time and/or frequency resources for transmitting physical random access channel (PRACH) signals. The resource allocation may be apportioned based on a type and class of PRACH signal. For instance, a UE may be assigned a first subset of resources to transmit regularly scheduled traffic and a second subset of resources to transmit on-demand traffic. Regularly scheduled traffic may include, for example, sensor measurements reported to the base station on a predetermined time interval (e.g., 24 hour time interval). In contrast, an on-demand traffic may include an impromptu transmission, initiated based on a detection of at least one reporting trigger (e.g., sensing an abnormality at the UE).

  • Patent number: 9713108
    Abstract: A method of fast synchronization for low coverage machine type communication (MTC) devices is proposed. A machine-specific synchronization signal “mSYNC” with higher density in time and frequency is transmitted from each base station for fast timing and frequency acquisition and tracking. The mSYNC has a relatively longer periodicity (i.e., >>5 ms) to reduce overhead and inter-cell interference. The higher time-frequency density of mSYNC is designed to improve latency and power consumption by allowing the machine to wake up just before the scheduled mSYNC transmission time and to re-synchronize or track synchronization with the network without the need for long averaging time.

  • Patent number: 9699320
    Abstract: A method and apparatus are provided for processing a request to instigate communication, received by a routing device associated with a plurality of terminals. The request relates to a communication to be established between a sender device of the request and at least one of the terminals. The method includes a step of comparing communication capabilities of said sender device with respective communication capabilities of one or more terminals, called addressee terminals, which are able to establish said communication, so as to identify at least one terminal having capabilities making it possible to establish with the sender device a communication of maximum quality. A call notification is transmitted to at least one of the addressee terminals, which is suitable for triggering on the addressee terminal a call presentation prompting a user to use, by priority, one of the terminals identified during the comparison step to establish the communication.

  • Patent number: 9681446
    Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may utilize orthogonal frequency division multiple access (OFDMA) for demodulating downlink messages and a combination of Gaussian minimum shift keying (GMSK) and single carrier frequency division multiple access (SC-FDMA) for uplink modulation. The uplink modulation process may include generating a symbol vector with an M-point discrete Fourier transform (DFT), filtering the symbol vector with a frequency domain Gaussian filter, generating a sample vector from the filtered symbol vector utilizing an inverse DFT, and modulating the sample vector utilizing GMSK. In some cases, the uplink modulation may be based on a narrowband resource allocation received from a base station.

  • Patent number: 9641422
    Abstract: According to an embodiment, a network device coupled to a local base station at a cell site is configured to automatically create a more optimal route for inter-base station traffic between the local base station and a remote base station. The network device automatically discovers a remote Internet Protocol address of the remote base station used for inter-base station traffic based upon traffic transmitted by the local base station to the network device or traffic transmitted between the local and remote base stations. In response, the network device automatically installs the more optimal route entry in a routing table of the network device, which enables the network device to route inter-base station traffic originated from the local base station and destined to the remote base station using a shorter path through the backhaul network instead of routing the traffic through a mobile core network.

  • Patent number: 9572067
    Abstract: A user of a communications network is prevented from consuming an excessive amount of channel bandwidth by restricting use of the channel in accordance with the type of data being downloaded to the user. The user is provided an initial number of credits. As the user consumes the credits, the data being downloaded is checked to determine if is permissible or non-permissible. Non-permissible data includes file-sharing files and movie downloads if user subscription does not permit such activity. If the data is permissible, the user is provided another allotment of credits equal to the initial allotment. If the data is non-permissible, the user is provided an allotment of credits less than the initial allotment. Various restriction policies also can be applied, such as levying additional fees and/or terminating the user's access to the channel. Also, incentives can be provided to entice the user curb the misuse.
