The communication may be narrowband communication. A UE may apparatus dynamically adjust a bandwidth configuration of the UE and communicates with a base station based on the dynamically adjusted bandwidth configuration.

Methods, systems, and devices for wireless communications that support physical uplink control channel (PUCCH) carrying hybrid automatic repeat request (HARQ-A) for multiple transmission reception point (multi-TRP) environments with non-ideal backhaul links are described. A user equipment (UE) may support multiple communication links with TRPs and receive distinct physical downlink control channel (PDCCH) messages that include downlink control information (DCI). The DCI may include a timing or resource indication index values for physical uplink control channel (PUCCH) transmission. Based on the index values, the UE may differentiate the received DCI indications. The UE may then schedule PUCCH transmissions, including hybrid automatic repeat request (HARQ) payloads, directed to the TRPs. In some examples, the scheduling may include mapping the PUCCH transmissions to resources or resource groups in configured PUCCH resource set. The UE may then transmit the PUCCH messages via one or more determined beams based on the indication index values.

The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.
