Patent number: 11844073Abstract: Techniques related to physical uplink control channel procedures are described. Briefly, in accordance with one embodiment, an Uplink Control Information (UCI) payload size is determined based at least in part on configuration information and Downlink Control Information (DCI). A Fifth Generation (5G) Physical Uplink Control Channel (xPUCCH) format is then determined based at least in part on the determined UCI payload size. Other embodiments are also disclosed and claimed.Type: GrantFiled: June 29, 2016Date of Patent: December 12, 2023Assignee: Apple Inc.Inventors: Gang Xiong, Glenn J.

Patent number: 11737171Abstract: Devices for and methods of providing low latency 5G FDD communications are generally described. A HARQ ACK/NACK for an xPDSCH is transmitted in the xPUCCH of the same or next subframe as the xPDSCH and xPDCCH. An xPUSCH is generated in the same subframe in response to an xPDCCH and HARQ ACK/NACK response is carried by another xPDCCH or xPHICH in the same or next sub frame. The xPDCCH and the xPUCCH are at opposite ends of the same subframe, DL and UL subframe are delayed relative to each other, or at least one of the DL and UL subframe has an additional blank portion, portion with data associated with another UE or portion that contains a reference signal, broadcast signal or control information.Type: GrantFiled: March 11, 2022Date of Patent: August 22, 2023Assignee: Apple Inc.Inventors: Gang Xiong, Glenn J.

Patent number: 11664958Abstract: Systems, methods, and baseband processors are provided to generate or process symbols in a synchronization subframe. In one example, a method includes selecting non-consecutive orthogonal frequency division multiplexing (OFDM) symbols in a synchronization subframe. A transmitter is instructed to transmit demodulation reference symbols (DM-RS) on identical first sets of subcarriers in respective OFDM symbols of the selected non-consecutive OFDM symbols for a Physical Broadcast Channel (PBCH) using a same transmit beam, wherein a gap between two subcarriers in a respective set of the identical first sets of subcarriers is three subcarriers. The transmitter is instructed to transmit the PBCH on identical second sets of subcarriers in respective OFDM symbols in the selected non-consecutive OFDM symbols.Type: GrantFiled: November 22, 2021Date of Patent: May 30, 2023Assignee: Apple Inc.Inventors: Peng Lu, Qiaoyang Ye, Gang Xiong, Glenn J.

Patent number: 11190327Abstract: A method is provided to generate and control transmission of reference symbols in a synchronization subframe, wherein a reference symbol includes reference values mapped to a block of K subcarriers. The method includes generating data corresponding to a basic subsequence of K?R1?R2 reference values, where R1 and R2 are integers such that 1?R1+R2<K, and mapping the data corresponding to the basic subsequence to an original range of K?R1?R2 contiguous subcarriers in the block such that there is a first set of R1 unmapped subcarriers above the original range of subcarriers and a second set of R2 unmapped subcarriers below the original range of subcarriers. Data corresponding to last R1 values in the basic subsequence is mapped to the first set of unmapped subcarriers. Data corresponding to first R2 values in the basic subsequence is mapped to the second set of unmapped subcarriers.Type: GrantFiled: April 13, 2017Date of Patent: November 30, 2021Assignee: Apple Inc.Inventors: Peng Lu, Qiaoyang Ye, Gang Xiong, Glenn J.

Patent number: 11134484Abstract: Techniques for xPDCCH (5G (Fifth Generation) Physical Downlink Control Channel) design are discussed. In various aspects, xPDCCH can be transmitted via one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols, with each OFDM symbol comprising a xPDCCH search space. Each xPDCCH search space can have one or two distinct xPDCCH sets, with each xPDCCH set having a xCCE (5G Control Channel Element) starting position that can be based on one of several predetermined rules, and can depend on one or more factors.Type: GrantFiled: September 27, 2016Date of Patent: September 28, 2021Assignee: Intel CorporationInventors: Gang Xiong, Glenn J.

Patent number: 10855407Abstract: 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.Type: GrantFiled: December 29, 2016Date of Patent: December 1, 2020Assignee: Apple Inc.Inventors: Gang Xiong, Glenn J.
