Abstract: A method of uplink control information (UCI) transmission over physical uplink control channel (PUCCH) is proposed. The UCI may include different information and being transmitted using different PUCCH formats. Under certain scenarios, the coded UCI bitstream size may not be assigned to an integer number of modulated symbols. To eliminate unnecessary processing as well as to utilize every bit in a modulated resource element, it is proposed to adjust the UCI codeword size to be a multiple of PUCCH modulation order.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines that a first uplink control channel is scheduled to be transmitted in a first slot set including multiple consecutive slots and that a second uplink control channel is scheduled to be transmitted in a second slot set including one or more consecutive slots. The UE determines that the first uplink control channel and the second uplink control channel overlap in a first slot that is included in both the first slot set and the second slot set. The UE determines that a particular uplink control channel of the first uplink control channel and the second uplink control channel is to be transmitted in the first slot based on a predetermined rule. The UE transmits the particular uplink control channel in the first slot.

Abstract: Various methods of control-less data transmission for NB-IoT/NR devices have been proposed to improve efficiency and system capacity in cellular networks. In a first embodiment, a PDCCH-less operation is performed between eNB and UE. UE will blindly decode some PDSCH subframes according to the parameters configured by higher layer. In a second embodiment, a PDCCH-lite operation is performed between eNB and UE. UE may use one PDCCH to schedule more than one subsequent PDSCH resources. In a third embodiment, an extremely compact DCI (E-DCI) format is used between eNB and UE. When the same assignment parameters are used by the eNB for the UE, DCI overhead may be reduced by E-DCI. In a fourth embodiment, direct data transmission in PDCCH is performed between eNB and UE. Data transmission is directly transmitted by PDCCH with a new DCI format.

IPC: H04L1/00
Abstract: A method of new radio physical broadcast channel (NR-PBCH) bit mapping is proposed to improve for NR-PBCH decoding performance under Polar codes. NR-PBCH carries 32 information bits and 24 CRC bits. Specifically, NR-PBCH uses 512-bit Polar codes to carry total 56 data bits. Different Polar code bit channels have different channel reliability. As a general rule, the most reliable Polar code bit channels are used for the 56 data bits. In accordance with a novel aspect, within the 32 NR-PBCH information bits, some of the information bits that can be known to the decoders under certain conditions and therefore are placed at the least reliable Polar code bit positions. As a result, by mapping the NR-PBCH data bits properly at the input bit positions of Polar codes, the NR-PBCH decoding performance is improved when the known bits a priori can be exploited.

Abstract: Various solutions for multiplexing physical uplink control channels with respect to user equipment (UE) and network apparatus in mobile communications are described. A UE may receive control information from a network apparatus. The UE may multiplex a short physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) in a transmission time interval (TTI) according to the control information. The UE may transmit the multiplexed short PUCCH and PUSCH to a network apparatus. The short PUCCH and the PUSCH may be multiplexed by time division multiplexing (TDM) or frequency division multiplexing (FDM). The control information may be configured by radio resource control (RRC) layer signaling or indicated by physical layer signaling or L1 signaling.

Abstract: Concepts and examples pertaining to short physical uplink control channel (PUCCH) in New Radio (NR) networks are described. A processor of a user equipment (UE) configures a short PUCCH comprising one or two orthogonal frequency-division multiplexing (OFDM) symbols. In configuring the short PUCCH, the processor selects a sequence from a plurality of different sequences each of which representative of a respective uplink control information (UCI). The selected sequence is transmitted by the processor in the short PUCCH to a node of a wireless communication network.

Abstract: A unified frame structure is scalable to meet the 5G new radio requirements, to support flexible TDD configurations, to support multiple numerologies, and to adapt to the channel properties of different spectrums up to 100 GHz. Multiple numerologies with 15 KHz subcarrier spacing and its integer or 2m multiple are proposed, where m is a positive integer. Under the unified frame structure, each radio frame is a basic operation time unit in higher layer and comprises a plurality of slots, and each slot within a radio frame is a basic scheduling time unit in physical layer and comprises a predefined number of OFDM symbols. A semi-static configuration configures DL-only slot type via system information or higher-layer signaling, while a physical layer signaling is used to dynamically configure flexible slot types.

Abstract: An embodiment of the invention provides a telecommunications method to be performed by a first telecommunications device while trying to transmit a data block to a second telecommunications device. According to the embodiment, the first telecommunications device determines whether a first set of early termination criteria is satisfied. Then, if the first set of early termination criteria is satisfied, the first telecommunications device further determines whether a second set of early termination criteria is satisfied. The second set of early termination criteria is different from the first set of early termination criteria. If both the first set of early termination criteria and the second set of early termination criteria are satisfied before the first telecommunications device finishes transmitting the data block, the first telecommunications device reduces a transmission power.
