  • Patent number: 10728774
    Abstract: An apparatus and a method for feeding back data receiving status, applied to a system, are provided. The method includes sequencing, by a User Equipment (UE), downlink subframes for transmitting data with respect to each Component Carrier (CC), generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing, where X?M, wherein M is the number of downlink subframes on each CC, and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly, the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission, saves the uplink overheads occupied by the receiving status feedback information, and increases the uplink coverage area.

  • Patent number: 10721723
    Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support transmitting/receiving downlink control information (DCI) carrying a downlink grant or an uplink grant. A method includes detecting a reference length based on an effective length of a downlink (DL) grant DCI and an effective length of an uplink (UL) grant DCI and calculating a length difference based on the effective DL grant DCI length and the effective UL grant DCI length. A length of a padding field in the DL grant DCI and/or the UL grant DCI is set equal to the calculated length difference such that the lengths of the DL grant DCI and UL grant DCI are both equal to the reference length. Padding bits are inserted in the padding field of the DL grant DCI and/or the UL grant DCI. Thereafter, the DL grant DCI and/or the UL grant DCI is encoded and transmitted to a scheduled entity.

    Abstract: Embodiments provide a communication method, terminal, and a base station. The method includes: receiving, by terminal, a reference signal sent by a base station; and obtaining, by the terminal, channel energy of a narrow beam by measuring the reference signal, where the narrow beam is a directional beam. According to the communication method in the embodiments of the present disclosure, the terminal may obtain the channel energy of the narrow beam by measuring the reference signal. Compared with the prior art in which channel energy of a narrow beam is measured on a base station side, a difference is that the terminal can more accurately estimate the channel energy of the narrow beam. That is, the channel energy of the narrow beam estimated by the terminal can more accurately reflect channel quality, and transmission efficiency can be improved.

  • Patent number: 10694514
    Abstract: An adaptive two-stage downlink control channel structure is utilized for control channel transmission with code block group (CBG) retransmission for 5G and other next generation wireless systems. In an aspect, the first stage of the two-stage downlink control channel structure utilizes a defined format (e.g., having a fixed length) and provides information that is employable to determine the length and/or coding scheme of the second stage. In another aspect, the second stage of the two-stage downlink control channel structure utilizes a variable length/size to indicate the CBGs that are scheduled to be retransmitted (e.g., by employing a variable length bitmap). As an example, the length/size is varied based on a length/size of a transport block, from which the CBGs have been generated.

  • Patent number: 10687385
    Abstract: In a communication system in which a plurality of bearers are set up between UE and one or more PGWs, a PGW measures an idle time for each bearer and determines whether or not the measured idle time has reached an idle timer threshold value which is determined in advance for each of the plurality of bearers (Step 1). Then, when it is determined that the idle time for one bearer, for example, bearer 2, has reached the idle timer threshold value (Step 2), a PGW2 requests an MME to release bearer 2 via an SGW2 (Steps 3 and 4), and the MME performs a process of releasing bearer 2 in response to the request (Step 5 and the like).

  • Patent number: 10674501
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may indicate time and frequency resources for a low latency physical downlink control channel (sPDCCH), which may be different from another physical downlink control channel (PDCCH), to a user equipment (UE). The base station may then transmit a common sPDCCH (CsPDCCH) message to indicate which low latency control channel elements (sCCEs) are used for sPDCCH transmission during a given subframe. In some cases, the signaling used to indicate the initial resource allocation for sPDCCH may be infrequent relative to the CsPDCCH transmissions. If some of the resources initially allocated for sPDCCH are not actually used for sPDCCH during a subframe, the base station and the UE may use those resources for communicating data. For example, the base station may transmit data using a low latency physical downlink shared channel (sPDSCH) to the UE using those resources.
