Abstract: A method for a multicast service is provided. In this example, the method includes receiving, by a user equipment (UE), a control format including a resource allocation field from a base station (BS), the resource allocation field indicating a starting resource block (RB) index and an RB range, obtaining a set of RBs allocated for a multicast physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) based on a starting RB location and the RB range; wherein the starting RB location is associated with the starting RB index and at least one of a reference RB location or an assigned sub-band; and transmitting or receiving, by the UE, data over at least one RB of the set of RBs allocated for the multicast PDSCH or PUSCH.

Abstract: Aspects of the present disclosure provide methods, devices and systems that limit a number of DCI payload sizes in order to limit the complexity of processing needed to perform blind decoding of the DCI payload. Various embodiments are provided that limit the number of DCI payload sizes. A base station determines the payload sizes to be used for a given time slot and once generated, transmits the DCI to one or more UEs. The UE is responsible for receiving the DCI and performing blind decoding to decode the information intended for the UE. In some embodiments, limiting the number of payload sizes may result in some DCI content that is smaller than the allotted DCI payload size being padded with zero bits to fill the allotted DCI payload size.

Abstract: The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (μ), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k0,xμ) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.

Abstract: Methods and apparatus are provided for wireless communication in which a downlink control information (DCI) is transmitted in a physical downlink control channel (PDCCH) in a first bandwidth part (BWP). A UE is responsible for determining a starting resource block (RB) for a data transmission allocated by the DCI based on a value of a frequency domain resource allocation field in the DCI, a reference RB, and a reference size of a second BWP. The data transmission can then be transmitted, in the case of, for example, PUSCH, by a UE or received, in the case of, for example, PDSCH.

Abstract: This application provides a data communication method, an apparatus, and a non-transitory computer readable storage medium. In one embodiment, the base station sends a master information block comprising first information for determining a first location in frequency domain, sends a first demodulation reference signal usable for demodulating a first data channel that carries a system information block, wherein a first physical resource block index of the first demodulation reference signal is based on the first location, sends the system information block or radio resource control signaling comprising second information for determining a second location in frequency domain, and sends or receives a second demodulation reference signal usable for demodulating a second data channel other than the first data channel, wherein a second physical resource block index of the second demodulation reference signal is based on the second location.
