Abstract
Systems and methods for wireless communication systems are disclosed. In one aspect, the wireless communication method includes identifying, by a wireless communication device, a plurality of Physical Random Access Channel (PRACH) resource configurations. The method includes sending, by the wireless communication device to a wireless communication node, based on a selected one of the plurality of PRACH resource configurations, a first message to initiate a random access process.
Claims19
A wireless communication method, comprising:
- identifying, by a wireless communication device, a plurality of Physical Random Access Channel (PRACH) resource configurations;
- selecting, by the wireless communication device, a PRACH resource configuration based on at least one of a frequency-domain arrangement or a time-domain arrangement of the plurality of PRACH resource configurations;
- and
- sending, by the wireless communication device to a wireless communication node, based on the selected PRACH resource configuration of the plurality of PRACH resource configurations, a first message to initiate a random access process.
A wireless communication method, comprising:
- determining, by a wireless communication node, a plurality of Physical Random Access Channel (PRACH) resource configurations;
- receiving, by the wireless communication node from a wireless communication device, a PRACH resource configuration selected from the plurality of PRACH resource configurations based on at least one of a frequency-domain arrangement or a time-domain arrangement of the plurality of PRACH resource configurations;
- and
- receiving, by the wireless communication node from the wireless communication device, a first message initiating a random access process, wherein the first message is configured based on a selected PRACH resource configuration of the plurality of PRACH resource configurations.
A wireless communication device, comprising:
- at least one processor configured to:
- identify a plurality of Physical Random Access Channel (PRACH) resource configurations;
- select a PRACH resource configuration based on at least one of a frequency-domain arrangement or a time-domain arrangement of the plurality of PRACH resource configurations;
- and
- send, via a transmitter to a wireless communication node, based on the selected PRACH resource configuration of the plurality of PRACH resource configurations, a first message to initiate a random access process.
A wireless communication node, comprising:
- at least one processor configured to:
- determine a plurality of Physical Random Access Channel (PRACH) resource configurations;
- receive, via a receiver from a wireless communication device, a PRACH resource configuration selected from the plurality of PRACH resource configurations based on at least one of a frequency-domain arrangement or a time-domain arrangement of the plurality of PRACH resource configurations;
- and
- receive, via the receiver from the wireless communication device, a first message initiating a random access process, wherein the first message is configured based on the selected PRACH resource configuration of the plurality of PRACH resource configurations.
