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.
Claims26
A method for wireless communications performed by a base station (BS), comprising:
- providing an indication of a scheduled physical random access channel (PRACH) region comprising a set of transmission resources for transmitting scheduled PRACH signals by a first user equipment (UE), wherein:
- the scheduled PRACH region is within a narrowband region of a wider system bandwidth,
- the scheduled PRACH region is a subset of a set of PRACH resources indicated by the BS, and
- the indication comprises a parameter indicating a starting offset of the scheduled PRACH region from the set of PRACH resources;
- and
- transmitting a first command to the first UE to transmit a scheduled PRACH signal using transmission resources in the scheduled PRACH region.
A method for wireless communications performed by a user equipment (UE), comprising:
- receiving a command from a base station (BS) to transmit a scheduled physical random access channel (PRACH) signal to the BS;
- obtaining an indication of a scheduled PRACH region comprising a set of transmission resources for transmitting scheduled PRACH signals to the BS, wherein:
- the scheduled PRACH region is within a narrowband region of a wider system bandwidth,
- the scheduled PRACH region is a subset of a set of PRACH resources indicated by the BS,
- the indication comprises a parameter indicating a starting offset of the scheduled PRACH region from the set of PRACH resources;
- and
- transmitting the PRACH signal to the BS using transmission resources in the scheduled PRACH region.
An apparatus for wireless communications, comprising:
- at least one processor configured to:
- provide an indication of a scheduled physical random access channel (PRACH) region comprising a set of transmission resources for transmitting scheduled PRACH signals by a first user equipment (UE), wherein:
- the scheduled PRACH region is within a narrowband region of a wider system bandwidth,
- the scheduled PRACH region is a subset of a set of PRACH resources indicated by the BS,
- the indication comprises a parameter indicating a starting offset of the scheduled PRACH region from the set of PRACH resources;
- and
- transmit a first command to the first UE to transmit a scheduled PRACH signal using transmission resources in the scheduled PRACH region;
- and
- a memory coupled to the at least one processor.
