Embodiment Construction

[0043] Aspects of the present disclosure were initially described in the context of wireless communication systems. Aspects of the described techniques may provide for extending the bandwidth of enhanced machine type communication (eMTC) physical uplink control channel (PUCCH) messages to support communication in specific bands of radio frequency spectrum. For example, the described techniques may include sending machine type communication (MTC) (or eMTC) PUCCH messages over multiple resource blocks (RBs) to provide sufficient bandwidth for MTC PUCCH message transmission in radio frequency bands, and in some In an example, the amount of data that can be transmitted in an MTC PUCCH message is extended. For example, the base station may select a payload size configuration for a user equipment (UE) MTC PUCCH message. The payload size configuration may also determine the amount of data the UE has available for MTC PUCCH messages. For example, payload size configuration can exten...

Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a configuration message indicating a payload size configuration for machine type communication(MTC) physical uplink control channel (PUCCH) messages. The UE may generate an MTC PUCCH message based at least in part on the payload size configuration and a PUCCH format of MTC uplink control information for transmission by the UE. The UE may transmit the MTC PUCCH message over a plurality of RBs in a frequency domain.
