Abstract
Aspects of the present disclosure provide techniques that may be applied in systems to allow for communication over a control channel utilizing a relatively narrow band (e.g., six physical resource blocks) based search space. An exemplary method, performed by a user equipment, generally includes identifying, within a subframe, a first search space to monitor for a downlink control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband size and monitoring at least the first search space for the downlink control channel transmitted in the subframe.
Claims27
A method for wireless communications by a user equipment (UE), comprising:
- identifying, within a subframe, a first search space to monitor for a downlink control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband size;
- and
- monitoring at least the first search space for the downlink control channel transmitted in the subframe.
A method for wireless communications by a base station (BS), comprising:
- identifying, within a subframe, a first search space for a user equipment (UE) to monitor for a downlink control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband size;
- and
- transmitting one or more downlink control channels to the UE in the first search space.
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor configured to:
- identify, within a subframe, a first search space to monitor for a downlink control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband size;
- and
- monitor at least the first search space for the downlink control channel transmitted in the subframe;
- and
- a memory coupled with the at least one processor.
