A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.

The present invention relates to a communication technique for combining IoT technology with 5G communication systems for supporting higher data transmission rates than 4G systems, and to a system therefor. The present disclosure can be applied, on the basis of 5G communication technology and IoT-related technology, to intelligent services such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security- and safety-related services. The present invention relates to a method for configuring temporal ordering of uplinks in a wireless communication system, more specifically, in 3GPP 5G New Radio (NR).

Method, systems and devices for transmitting system information in a wireless communication system are disclosed. The wireless communication method comprises transmitting a specific information associated with system information, SI, related to a first wireless terminal in a cell, wherein the SI related to the first wireless terminal comprise an instance different from the instance the SI related to a second wireless terminal.

A method of indicating a system information type, a network device and a user equipment are provided. The method includes: determining indication information configured to indicate a System Information (SI) type; sending, to a user equipment, a Physical Downlink Control Channel (PDCCH) carrying the indication information.

This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

A method and apparatus for accessing a NR cell in a mobile communication system are provided. Method for accessing a NR cell includes receiving in a first cell, by a terminal from a base station, a System Information Block1, monitoring, by the terminal, Physical Downlink Control Channel (PDCCH) for Random Access Response based at least in part on a specific ra-ResponseWindow and a specific ra-SearchSpace.

This application provides an uplink information transmission method and apparatus. The method includes: determining a value of a power control parameter in a value set of the power control parameter, where any value set of the power control parameter includes at least two values; sending indication information to a terminal device, where the indication information is used to indicate the value of the power control parameter; and receiving uplink information, where the uplink information is from the terminal device at a transmit power adjusted based on the value of the power control parameter.

Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, at a user-equipment (UE), at least one pilot signal via a secondary cell, receive, via a primary cell, a first message triggering reporting of at least one preferred beam for communication via the secondary cell, determining the preferred beam based on the at least one pilot signal, transmitting, via the primary cell, a report indicating the at least one preferred beam, and communicating data via the secondary cell and via the preferred beam.
