Abstract
Reference symbols can be received. A first received power of the reference symbols on a first antenna port can be measured. A second received power of the reference symbols on a second antenna port that is coupled to and uses the same transmit power amplifier as the first antenna port can be measured. A received power difference can be determined based on a relationship between the second received power and the first received power. A value of the received power difference can be transmitted.
Claims20
A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive reference symbols;
- measure a first received power of the reference symbols on a first antenna port;
- measure a second received power of the reference symbols on a second antenna port that is coupled to and uses a same transmit power amplifier as the first antenna port;
- determine a received power difference based on a relationship between the second received power and the first received power;
- and
- transmit a value of the received power difference.
A processor for wireless communication, comprising:
- at least one controller coupled with at least one memory and configured to cause the processor to:
- receive reference symbols;
- measure a first received power of the reference symbols on a first antenna port;
- measure a second received power of the reference symbols on a second antenna port that is coupled to and uses a same transmit power amplifier as the first antenna port;
- determine a received power difference based on a relationship between the second received power and the first received power;
- and
- transmit a value of the received power difference.
A method performed by a user equipment (UE), the method comprising:
- receiving reference symbols;
- measuring a first received power of the reference symbols on a first antenna port;
- measuring a second received power of the reference symbols on a second antenna port that is coupled to and uses a same transmit power amplifier as the first antenna port;
- determining a received power difference based on a relationship between the second received power and the first received power;
- and
- transmitting a value of the received power difference.
A base station for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the base station to:
- send reference symbols from a network entity antenna port;
- send a signal to take measurements of received power using the sent reference symbols by taking a first measurement of received power on a first antenna port and by taking a second measurement of received power on a second antenna port that uses a same power amplifier for transmission as the first antenna port;
- and
- send a signal to determine and report a power difference resulting from a relationship between the first measured received power on the second antenna port and the second measured received power on the first antenna port.
