Abstract
Various aspects described herein relate to techniques for signaling and channel design in wireless communications systems (e.g., a 5G NR system). In an aspect, a method includes identifying a direct current (DC) subcarrier of a synchronization bandwidth, determining whether a synchronization signal transmits on, punctures, or rate matches around the DC subcarrier, and performing synchronization channel processing based on the determination.
Claims24
A method for wireless communications, comprising:
- identifying a direct current (DC) subcarrier of a synchronization bandwidth;
- determining whether a synchronization signal transmits on, punctures, or rate matches around the DC subcarrier;
- and
- performing synchronization channel processing based on the determination.
An apparatus for wireless communications, comprising:
- a receiver;
- a memory configured to store instructions;
- and
- at least one processor communicatively coupled with the receiver and the memory, wherein the at least one processor is configured to execute the instructions to:
- identify a direct current (DC) subcarrier of a synchronization bandwidth;
- determine whether a synchronization signal transmits on, punctures, or rate matches around the DC subcarrier;
- and
- perform synchronization channel processing based on the determination.
A method for wireless communications, comprising:
- identifying a first subcarrier spacing used for a first resource block (RB);
- identifying at least a second subcarrier spacing and a guard band used for a second RB, wherein the second subcarrier spacing is less than the first subcarrier spacing;
- and
- generating the second RB using at least the second subcarrier spacing with the guard band.
An apparatus for wireless communications, comprising:
- a memory configured to store instructions;
- and
- at least one processor communicatively coupled with the memory, wherein the at least one processor is configured to execute the instructions to:
- identify a first subcarrier spacing used for a first resource block (RB);
- identify at least a second subcarrier spacing and a guard band used for a second RB, wherein the second subcarrier spacing is less than the first subcarrier spacing;
- and
- generate the second RB using at least the second subcarrier spacing and the guard band.
