Abstract
Briefly, in accordance with one or more embodiments, apparatus of an evolved NodeB (eNB) comprises circuitry to configure one or more parameters for a 5G master information block (xMIB). The xMIB contains at least one of the following parameters: downlink system bandwidth, system frame number (SFN), or configuration for other physical channels, or a combination thereof. The apparatus of the eNB comprises circuitry to transmit the xMIB via a 5G physical broadcast channel (xPBCH) on a predefined resource, the xPBCH comprising a xPBCH. The xPBCH may use a DM-RS based transmission mode, and a beamformed xPBCH may be used for mid band and high band.
Claims20
A base station, comprising:
- radio frequency (RF) circuitry configured to communicate with a user equipment (UE) in a fifth generation (5G) network;
- and
- a processor communicatively coupled to the RF circuitry and configured to perform operations, comprising:
- configuring one or more parameters for a 5G master information block (MIB), wherein the 5G MIB comprises a downlink system bandwidth, a 5G physical downlink control channel (PDCCH) configuration and a system frame number, SFN;
- generating a 5G physical broadcast channel (PBCH) from the 5G MIB, wherein a cyclic redundancy check (CRC) is attached to the 5G MIB;
- applying a Demodulation Reference Symbol (DM-RS) based transmission for the 5G PBCH, wherein a same beamforming weight is applied for the DM-RS and for data symbols allocated for the 5G PBCH;
- and
- transmitting the 5G MIB via the 5G PBCH on a predefined resource and a 5G frequency band over 6 giga hertz (GHz).
