Abstract
An apparatus for user equipment (UE). The UE comprises a transceiver configured to receive an indication of a partial subframe configuration over an unlicensed spectrum in a licensed assisted access (LAA) cell. The UE further includes at least one processor configured to determine a resource element (RE) mapping rule based on the indication of the partial subframe configuration; and identify an RE position of at least one reference signal to be received from the eNB based on the RE mapping rule.
Claims20
A user equipment (UE), the UE comprising:
- a transceiver configured to receive, from an eNodeB (eNB), an indication of a partial subframe configuration over an unlicensed spectrum in a licensed assisted access (LAA) cell;
- and
- at least one processor configured to:
- determine a resource element (RE) mapping rule based on the indication of the partial subframe configuration;
- and
- identify an RE position of at least one reference signal to be received from the eNB based on the RE mapping rule.
An eNodeB (eNB), the eNB comprising:
- a transceiver configured to transmit, to a user equipment (UE), an indication of a partial subframe configuration over an unlicensed spectrum in a licensed assisted access (LAA) cell;
- and
- at least one processor configured to when a resource element (RE) mapping rule is used based on the indication of the partial subframe configuration, configure an RE position of at least one reference signal to be transmitted to the UE based on the RE mapping rule.
A user equipment (UE), the UE comprising:
- a transceiver configured to receive, from an eNodeB (eNB), an indication of a bandwidth configuration of a licensed assisted access (LAA) cell over an unlicensed spectrum;
- and
- at least one processor configured to determine a frequency location of an unlicensed physical broadcasting channel (U-PBCH) to be received from the eNB based on the indication of the bandwidth configuration.
