  • Patent number: 10855407
    Abstract: Devices and methods of receiving a PDCCH-less xSIB are generally described. A UE receive a xPBCH that occurs in a 0th or a 25th subframe and an ePBCH in an ePBCH transmission block. The ePBCH has the xSIB and is received on different Tx beams. The ePBCH spans consecutive symbols on the same subcarrier and with the same ePBCH symbol. The frame number, subframe number and symbol number of the ePBCH is dependent on a subframe number and symbol number of the xPBCH. The number of beams received for a particular symbol is dependent on a total number of beams, a beam sweeping time for the beams and a transmission periodicity of the xPBCH and ePBCH. The UE also uses different OCCs to demodulate a DMRS from different APs, in a same PRB as the ePBCH.

  • Patent number: 10609693
    Abstract: A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.

  • Patent number: 10594432
    Abstract: An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.

  • Patent number: 10575292
    Abstract: Embodiments of the present invention provide methods for transmitting and receiving a control channel, a base station, and a user equipment, which relate to the communication field, and can solve a transmission problem of available changing transmission resources caused by introduction of an E-PDCCH. A method includes determining, by a terminal device, a resource set and resource elements (REs) of predetermined overheads in the resource set. The REs of the predetermined overheads include an RE of at least one of a paging channel and a synchronization channel, with at least one of following REs: an RE of a channel state information-reference signal (CSI-RS), an RE of a cell-specific reference signal (CRS), an RE of a demodulation reference signal (DMRS), or a muted RE. The terminal device receives from a base station, a control channel on an RE subset comprised in the resource set, wherein the RE subset comprises a part of the REs in the resource set and do not contain the REs of the predetermined overheads.

  • Patent number: 10574273
    Abstract: Embodiments described herein provide a method for dynamically scaling log-likelihood ratio (LLR) values of received data bits before decoding the received data bits. A plurality of data bits are received corresponding to a data packet. A first set of data bits of a first type are determined from the plurality of data bits based on a modulation scheme corresponding to the received data bits. A first LLR histogram is generated corresponding to the first set of data bits of the first type. A first scaling factor is calculated based on the first LLR histogram such that a first LLR value range corresponding to the first set of data bits is expanded to a maximum LLR value range. All LLR values are scaled by the first scaling factor. The scaled LLR values corresponding to the plurality of data bits are sent to a decoder.

  • Patent number: 10542512
    Abstract: There is provided a method for time synchronization of stations (STAs) in a wireless local area network. An access point (AP) transmits a request to at least two STAs for the at least two STAs to transmit a response to the AP, the request indicating which frequency sub-band each of the at least two STAs is to use for transmitting the response. Responses to the request are received from the at least two STAs, wherein each of the responses comprises orthogonal frequency-division multiple access (OFDMA) symbols. For each of the at least two STAs, a time delay is determined based on the responses. Then, control signalling is transmitted to the at least two STAs, the control signalling comprising time alignment commands for the at least two STAs, wherein each time alignment command is based on the time delay for one of the at least two STAs.

  • Patent number: 10542530
    Abstract: Certain aspects of the present disclosure relate to techniques for reducing the decoding complexity for low cost devices (e.g., low cost UEs). One technique may include simplifying the PDCCH format. This may include generating a compact DCI format for transmitting DCI to a low cost device. The compact DCI format may correspond to at least one standard DCI format used by a regular UE and may comprise a reduced number of bits when compared to the standard DCI format. Another technique may include reducing the number of blind decodes. This technique may include selecting a set of resources for transmitting DCI from a limited set of decoding candidates, such that a receiving low cost device need only perform blind decodes for the limited set of decoding candidates.
