A method for wireless communication involving high-reliability ultra-reliable low latency communication (URLLC) control and data channel transmissions is disclosed. The method includes receiving, by a user equipment (UE), first downlink control information (DCI) in a first control resource set (CORESET), the first DCI providing scheduling information for transmission of first data over a first physical downlink shared channel (PDSCH), receiving, by the UE, second DCI in a second CORESET, the second DCI providing scheduling information for transmission of second data over a second PDSCH. The method also includes receiving, by the UE, the first data over the first PDSCH, and receiving, by the UE, the second data over the second PDSCH, where the first data and the second data are repetition data.

To provide a base station apparatus, a terminal apparatus, and a communication method that enable to secure high reliability and low latency of URLLC. An apparatus includes a receiver configured to detect a DCI format, and a transmitter configured to perform first data transmission based on a first DCI format and second data transmission based on a second DCI format. The receiver detects the first DCI format for the first data transmission in a first CC, and detects the second DCI format for the second data transmission in a second CC. In a case that the first data transmission and the second data transmission overlap in a time domain, and a sum of transmit power of the first data transmission and transmit power the second data transmission exceeds maximum transmit power, the transmitter allocates the transmit power to the first data transmission not to exceed the maximum transmit power. Remaining transmit power being a difference between the maximum transmit power and the transmit power of the first data transmission is allocated as the transmit power of the second data transmission.

This application provides a communication method, including: receiving, by a terminal device, configuration information, where the configuration information is used to configure M component carriers, and M is a positive integer; determining, by the terminal device, N types of DCI sizes based on the configuration information; and if N is greater than a first threshold, determining, by the terminal device, Q types of DCI sizes, and detecting a downlink control channel in a first time unit based on the Q types of DCI sizes, where Q is less than or equal to the first threshold. According to the communication method provided in this application, a capability of detecting a DCI size by a terminal device can be fully used.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station transmitting a modulation and coding scheme index corresponding to a modulation and coding scheme table to a user equipment (UE). The modulation and coding scheme index may be applied to encoding or decoding a transport block. The modulation and coding scheme may be associated with at least two modulation orders or a differential indication according to a modulation and coding scheme table. To determine which of the modulation orders for processing the transport block, the UE and the base station may use a prior modulation order associated with a prior transmission of the transport block. The UE may process the transport block by encoding or decoding the transport block based at least in part on the determined modulation order.

Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of whether a first physical downlink shared channel (PDSCH) communication is to be punctured in a set of resources in which a second PDSCH communication at least partially overlaps with the first PDSCH communication, or both the first PDSCH communication and the second PDSCH communication are to be transmitted in the set of resources. The mobile station may decode the first PDSCH communication based at least in part on the indication. Numerous other aspects are provided.

A user terminal according to one aspect of the present disclosure includes a receiving section that receives information indicating start of report of semi-persistent channel state information (SP-CSI (Semi-Persistent Channel State Information) report), and a control section that determines timing of the SP-CSI report, based on whether or not there is relation between timing of a feedback report for reception of the information and the timing of the SP-CSI report. According to one aspect of the present disclosure, SP-CSI report and/or detection can be appropriately controlled even when SP-CSI report activation is indicated by using MAC CEs (Medium Access Control Control Elements).

By means of the technical solution provided in the present invention, the utilization rate of resources can be improved.

A signal transmitter and a signal receiver for interpreting a received message are provided. The receiver is configured to perform the steps of: decoding a first part of the message using a channel decoding scheme with a predefined set of decoding parameters to form a first data block; and subsequently decoding a second part of the message using the channel decoding scheme with decoding parameters that are at least partially dependent on the content of the first data block.
