Configuring control information comprises determining a frequency offset including an RB and RE level frequency offset, where the frequency offset is determined based on a lowest RE of an SS/PBCH block and a lowest RE of CORESET for RMSI, jointly configuring, using a first field of 4 bits, the RB level frequency offset with a multiplexing pattern of the SS/PBCH block and the CORESET, a BW of the CORESET, and a number of symbols for the CORESET for a combination of a SCS of the SS/PBCH block and a SCS of the CORESET, configuring using a second field of the 4 bits generating an MIB including the RB level frequency offset and the RE level frequency offset; and transmitting, to a UE, the MIB over a PBCH.

An operating method and an apparatus are provided in which state information is received from at least one of a higher layer and a plurality of terminals. A respective allocation resource is determined for each of the plurality of terminals, based on the state information. A respective guard band is determined to be allocated for each of the plurality of terminals, based on the respective allocation resource. Respective resource blocks (RBs) are determined for each of the plurality of terminals, based on the respective guard band. Information about the determined respective RBs is transmitted to respective terminals of the plurality of terminals.

In a case of using a different frequency band that is different from a frequency band including one or a plurality of frequency ranges, a terminal applies initial access configurations including a format of an initial access signal, the format being different from that for the frequency band. The terminal transmits the initial access signal via an initial access channel set based on the applied initial access configurations.

Provided are a method and a device for determining the application delay value of a minimum scheduling offset restriction in a wireless communication system. The method accesses a specific base station through a random access step, and then, if DCI which includes information for notifying of a change in the minimum scheduling offset restriction value in slot n of the scheduling cell is to be received from the base station, applies the changed minimum scheduling offset restriction value in slot n+X of the scheduling cell. Herein, the X value can be determined on the basis of two parameters such as Y and Z, the Y value is the minimum scheduling offset restriction value to be applied to a scheduled cell scheduled by the DCI, and the Z value is a value predetermined according to the subcarrier spacing of the scheduling cell. In addition, the DCI can increase, by 1, the Z value according to the temporal position at which the DCI is received within slot n.

The BWP switching method performed by the terminal includes: receiving a BWP activation signaling, switching to a first BWP according to the received BWP activation signaling; and receiving a positioning reference signal (PRS) on the first BWP, wherein the first BWP meets at least one of the following: a numerology of the first BWP is consistent with a numerology of the PRS; or a bandwidth of the first BWP is not less than a bandwidth of the PRS.

In a 5G network, a slice controller operating in a radio access network (RAN) is arranged to make predictions of channel state information (CSI) for user equipment (UE) on the network using a predictive propagation model. The slice controller uses the predicted CSI to schedule subcarriers and time slots associated with physical radio resources for data transmission on slices of the 5G network between a 5G radio unit (RU) and the UE to maximize network throughput on a slice for the radio spectrum that is utilized for a given time period. In view of the CSI predictions, the slice controller controls operations of the MAC (Medium Access Control) layer functions based on PHY (physical) layer radio resource subsets to schedule the subcarrier and time slots for data transmissions on a slice over the 5G air interface from RU to UE.
