Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type subframe definition may also be provided and/or used for support of such a reduced bandwidth.

Techniques and device for wireless communications are described. A wireless device may establish multiple connections with multiple transmission reception points (TRPs). The wireless device may receive downlink control information (DCI) messages from the multiple transmission points and may generate joint hybrid automatic repeat request feedback (HARQ) based on the received downlink control information messages. To support joint HARQ feedback, counter indices may be jointly assigned to the DCI messages generated by the multiple transmission reception points. The method for jointly assigning the DCI messages may be selected based on a level of interference detected in a communications channel. Also, to support joint HARQ feedback, a total counter index in an uplink DCI message may be configured to indicate a total number of DCI message transmitted from a first TRP and a second TRP during a time period.

Aspects of the present disclose provide various methods and apparatuses for communicating, controlling, and configuring component carrier and bandwidth part (BWP). A scheduling entity receives a capability report from a user equipment (UE). The capability report indicates a capability of the UE to utilize at least one of carrier aggregation (CA) or one or more bandwidth parts. The scheduling entity transmits a command to the UE to reconfigure at least one of a CA configuration or a bandwidth part (BWP) configuration. The scheduling entity determines an anticipated response timing of an acknowledgment (ACK) of the command based on the capability report received from the UE. The scheduling entity receives the ACK according to the anticipated response timing.

A Radio Access Network (RAN) wirelessly serves a User Equipment (UE) over a frequency channel based on a radio signal metric. The RAN comprises baseband circuitry and a radio. The baseband circuitry determines when multiple Physical Cell Identifiers (PCIs) are available to serve the UE. In response, the baseband circuitry selects some resource blocks in the frequency channel and generates a UE instruction to measure the radio signal metric for the selected resource blocks. The radio receives the UE instruction for the baseband circuitry and wirelessly transfers the UE instruction to the UE. The radio wirelessly receives a measurement report from the UE that indicates the radio signal metric for the selected resource blocks. The radio transfers the measurement report to the baseband circuitry. The baseband circuitry receives the measurement report and responsively schedules the UE in the selected resource blocks based on the radio signal metric.

Methods, systems, and devices for wireless communication are described. A wireless device may perform a listen before talk (LBT) procedure on a channel bandwidth using an energy detection (ED) threshold. The ED threshold being associated with a transmission bandwidth that is narrower than the channel bandwidth. The wireless device may also, responsive to a successful LBT procedure, transmit on the transmission bandwidth according to a frequency hopping pattern during a first channel occupancy time (COT). The frequency hopping pattern comprises a first resource allocation and a second resource allocation different from the first resource allocation.

A method by a UE for performing a random access procedure is provided. The method comprises transmitting a MSGA, monitoring a MSGB-RNTI within a MSGB window starting from an earliest symbol of an earliest PDCCH occasion after the MSGA transmission, receiving the MSGB in a first slot, the MSGB including a success RAR that contains a HARQ Feedback Timing Indicator, a Physical Uplink Control Channel (PUCCH) Resource Indicator, and a UE Contention Resolution Identity, determining, by a MAC entity, to instruct a lower layer to transmit a HARQ feedback in a second slot in response to the reception of the success RAR, delivering, by the MAC entity, the HARQ Feedback Timing Indicator and the PUCCH Resource Indicator to the lower layer, and performing, by the lower layer, a HARQ feedback delivery on an uplink (UL) resource.
