Abstract
Certain aspects of the present disclosure generally relate to wireless communications and more specifically to transmission resource management for ordered physical random access channel (PRACH) signals. An example method performed by a base station generally includes providing an indication of a set of transmission resources, within a narrowband region of a wider system bandwidth, for transmitting scheduled physical random access channel (PRACH) signals by a first user equipment (UE) and transmitting a command to the first UE to transmit a scheduled PRACH.
Claims20
A method for wireless communications performed by a user equipment (UE), comprising:
- receiving a command from a base station (BS) to transmit a physical random access channel (PRACH) signal to the BS;
- obtaining an indication of a PRACH region comprising a set of transmission resources within a narrowband region of a wider system bandwidth for transmitting PRACH signals to the BS, wherein the PRACH region is a subset of PRACH resources indicated by the BS and the indication comprises a parameter indicating a starting offset of the PRACH region in the PRACH resources;
- and
- transmitting the PRACH signal to the BS using transmission resources in the PRACH region.
A method for wireless communications performed by a base station (BS), comprising:
- providing an indication of a PRACH region comprising a set of transmission resources within a narrowband region of a wider system bandwidth for transmitting PRACH signals by a user equipment (UE), wherein the PRACH region is a subset of PRACH resources indicated by the BS and the indication comprises a parameter indicating a starting offset of the PRACH region in the PRACH resources;
- and
- transmitting a command to the UE to transmit a PRACH signal using transmission resources in the PRACH region.
An apparatus for wireless communications, comprising:
- at least one processor configured to:
- receive a command from a base station (BS) to transmit a physical random access channel (PRACH) signal to the BS;
- obtain an indication of a PRACH region comprising a set of transmission resources within a narrowband region of a wider system bandwidth for transmitting PRACH signals to the BS, wherein the PRACH region is a subset of PRACH resources indicated by the BS and the indication comprises a parameter indicating a starting offset of the PRACH region in the PRACH resources;
- and
- transmit the PRACH signal to the BS using transmission resources in the PRACH region and a memory coupled to the at least one processor.
