The network units 104 may serve a number of remote units 102 within a serving area, for example, a cell or a cell sector via a wireless communication link. The network units 104 transmit DL communication signals to serve the remote units 102 in the time, frequency, and/or spatial domain.

In various embodiments, a remote unit 102 may receive information indicating a plurality of resource allocation mode configurations, wherein each resource allocation mode configuration of the plurality of resource allocation mode configurations corresponds to a logical channel of a plurality of logical channels. In some embodiments, the remote unit 102 may determine a plurality of data transmission scheduling modes for the plurality of logical channels, wherein each data transmission scheduling mode of the plurality of data transmission scheduling modes corresponds to a logical channel of the plurality of logical channels based a resource allocation mode configuration of the logical channel, and each data transmission scheduling mode comprises: a first scheduling mode; a second scheduling mode different from the first scheduling mode; or a third scheduling mode comprising the first scheduling mode and the second scheduling mode. In various embodiments, the remote unit 102 may transmit a buffer status report based on the plurality of the data transmission scheduling modes. Accordingly, the remote unit 102 may be used for multiple resource allocation mode configurations.
