Abstract
A wireless device receives, from a base station, configuration parameters indicating a plurality of first reference signals (RSs) including a first RS associated with a plurality of second RSs. Based on signal strengths of the plurality of first RSs, the first RS is selected from the plurality of first RSs. Based on signal strengths of the plurality of second RSs, a second RS is selected from the plurality of second RSs associated with the first RS. Based on the selected second RS, the wireless device transmits a random access preamble.
Claims20
A method comprising:
- receiving, by a wireless device from a base station, configuration parameters indicating a plurality of first reference signals (RSs) comprising a first RS associated with a plurality of second RSs;
- selecting, based on signal strengths of the plurality of first RSs, the first RS from the plurality of first RSs;
- selecting, based on signal strengths of the plurality of second RSs, a second RS from the plurality of second RSs associated with the first RS;
- and
- transmitting, based on the selected second RS, a random access preamble.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions, that when executed by the one or more processors, cause the wireless device to:
- receive, from a base station, configuration parameters indicating a plurality of first reference signals (RSs) comprising a first RS associated with a plurality of second RSs;
- select, based on signal strengths of the plurality of first RSs, the first RS from the plurality of first RSs;
- select, based on signal strengths of the plurality of second RSs, a second RS from the plurality of second RSs associated with the first RS;
- and
- transmit, based on the selected second RS, a random access preamble.
A system comprising:
- a base station comprising:
- one or more first processors;
- and first memory storing first instructions, that when executed by the one or more first processors, cause the base station to:
- transmit configuration parameters indicating a plurality of first reference signals (RSs) comprising a first RS associated with a plurality of second RSs;
- and
- receive a random access preamble;
- and
- a wireless device comprising:
- one or more second processors;
- and second memory storing second instructions, that when executed by the one or more second processors, cause the wireless device to:
- receive the configuration parameters from the base station;
- select, based on signal strengths of the plurality of first RSs, the first RS from the plurality of first RSs;
- select, based on signal strengths of the plurality of second RSs, a second RS from the plurality of second RSs associated with the first RS;
- and
- transmit, based on the selected second RS, the random access preamble.
