A method of uplink transmission for a user equipment (UE) is disclosed. The method comprises receiving, from a base station (BS), a threshold; determining at least one uplink grant according to the threshold; performing a payload transmission on the at least one uplink grant while the UE is in an RRC inactive state; and not transmitting only padding bits for the payload transmission on the uplink grant.

A method by a user equipment (UE) is described. The method includes monitoring one or more of DCI formats, and determining whether a DCI size alignment procedure is complete based on a first condition and determine whether a DCI size alignment procedure is complete based on a second condition. In a first case that the UE does not indicate a first capability, the first condition is used. In a second case that UE indicates a first capability, the second condition is used The first condition is that, the total number of different DCI sizes configured to monitor is no more than 4 for the cell and the total number of different DCI sizes with C-RNTI configured to monitor is no more than 3 for the cell. The second condition is that, the total number of different DCI sizes configured to monitor is no more than 5 for the cell and the total number of different DCI sizes with C-RNTI configured to monitor is no more than 4 for the cell.

Systems and methods for transmission of full power uplink transmission in 5G networks are described. The gNB provides TPMI precoding information in DCI of a PDCCH in which the field size for precoding information and number of layers are fixed irrespective of the SRI. The gNB indicates in RRC signaling the use of codebook-based transmission for UL. If different SRS resources with different number of antenna ports are configured, the bitwidth of the SRI field is the maximum number of ports among the configured SRS resources in an SRS resource set with usage set to ‘codebook’. If the number of ports for a configured SRS resource in the set is less than the maximum number of ports, the most significant bits of the field have a value of ‘0’. The bitwidth is dependent on UE coherence capabilities and a maxrank of the UE.

A system includes a first encoder configured to receive first input bits and generate a first stream of first bits based on the first input bits, a bit generator configured to receive second inputs bits and generate a second stream of second bits based on the second input bits, and a PAM4 transmitter configured to receive the first stream of first bits and the second stream of second bits, and generate PAM4 symbols based at least on the first stream of first bits.

Systems, apparatuses and methods described herein provide a method for padding a signal extension of orthogonal frequency-division multiplexing (OFDM) symbols. A transceiver may obtain a plurality of data symbols for transmission, and determine that a number of information bits for a last symbol of the plurality of data symbols is not an integer value. A special padding rule may be applied to add padding bits to the last symbol. A number of coded bits for the last symbol may be determined when the number of information bits for the last symbol has changed, and the plurality of data symbols for data transmission may be encoded based on the determined number of coded bits for the last symbol.

This application provides a data stream processing method and a network element device. The method includes: obtaining, by a first network element device, a first data stream, where the first data stream includes a first data unit and a first data padding unit; and adjusting, by the first network element device, a quantity of second data padding units in the first data stream, where a relative position of the first data unit and the first data padding unit in the first data stream is the same as a relative position of the first data unit and the first data padding unit in a second data stream, and the second data stream is an adjusted first data stream. When adjusting a rate, the first network element device does not add or delete the first data padding unit in the first data stream.

Disclosed is a method for transmitting a broadcast signal. The method comprises formatting input streams with multiple data transmission channels, and the formatting step comprises adding a header indicating a format of a payload of the BBF.

Provided are a base station, user equipment and wireless communication methods related to DCI design for blind detection. A base station comprises: circuitry operative to align, for each DCI of a first group of DCIs, one of the size of the DCI of the first group and the size of a selected DCI of a second group of DCIs with the other, if the size of the DCI of the first group is different from the size of each DCI of the second group of DCIs, wherein the selected DCI of the second group is a DCI whose size is closest to the size of the DCI of the first group among DCIs of the second group having sizes larger than the size of the DCI of the first group or a DCI whose size is closest to the size of the DCI of the first group among DCIs of the second group having sizes smaller than the size of the DCI of the first group; and a transmitter operative to transmit the first group of DCIs and the second group of DCIs after the size alignment by the circuitry to a user equipment, wherein the size alignment is based on a rule which is known by the base station and the user equipment beforehand.

Disclosed is a method performed by a user equipment (UE) in a communication system, including receiving, from a base station, downlink control information including resource assignment information of a physical downlink shared channel (PDSCH), identifying a number of resource elements (REs) for the PDSCH based on the resource assignment information of the PDSCH, identifying a temporary transport block size (TBS) based on the number of REs for the PDSCH, identifying a TBS based on the temporary TBS, and receiving, from the base station, the PDSCH based on the TBS, wherein the number of REs for the PDSCH is identified by excluding a number of REs associated with a channel state information reference signal (CSI-RS) and a control channel.
