Abstract
Aspects described herein relate to sending, from a distributed unit (DU), a control signal that is transparent to communications on an uplink data channel and a random access channel, receiving, at the DU, a signal from a radio unit (RU) over resources for the random access channel, and decoding a random access communication from the signal at least in part by applying a phase compensation to the signal.
Claims17
An apparatus for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, wherein the one or more processors are configured to cause the apparatus to:
- send, to a radio unit (RU), a downlink control plane message of section type 1 for a random access channel with a same numerology as an uplink data channel;
- and
- receive a signal from the RU over resources for the random access channel.
A method of wireless communication performed by a distributed unit (DU), comprising:
- sending, to a radio unit (RU), a downlink control plane message of section type 1 for a random access channel with a same numerology as an uplink data channel;
- and
- receiving a signal from the RU over resources for the random access channel.
A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by an apparatus, causes the apparatus to:
- send, to a radio unit (RU), a downlink control plane message of section type 1 for a random access channel with a same numerology as an uplink data channel;
- and
- receive a signal from the RU over resources for the random access channel.
An apparatus for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, wherein the one or more processors are configured to cause the apparatus to:
- send, to a radio unit (RU), a downlink control plane message of section type 1 for a random access channel with a same numerology as an uplink data channel;
- and
- receive a signal from the RU over resources for the random access channel, wherein the downlink control plane message of section type 1 indicates the resources.
