Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDDCH includes a first DCI part and the PDSCH includes a second DCI part. In an example, a TBS associated with the PDSCH may be determined (e.g., either by factoring or ignoring resource elements associated with the second DCI part). In another example, the PDSCH may be associated with a modulation scheme with a constellation having constellation points, whereby the second DCI part in the PDSCH is restricted to a subset of the constellation points. In another example, rate-matching may be performed for one or more resource elements of the second DCI part.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example, the BS and UE each determine at least one timing value associated with an effective receive time for the PDCCH based upon a reference symbol of the PDSCH.

Abstract: Techniques for channel selection in a shared communication medium are disclosed. A communication apparatus may include one or more transceivers, a processor, and memory coupled to the processor and configured to store data and/or instructions. The one or more transceivers may be configured to monitor signaling on a plurality of available channels associated with a communication medium. The processor may be configured to determine an interference level for each of the plurality of available channels based on the monitored signaling, determine that the interference level for each of the plurality of available channels is greater than a first threshold, determine whether a triggering condition is met, and select the first channel of the plurality of channels as an operating channel for a primary radio access technology based on the triggering condition being met, the first channel having an interference level that is greater than a second threshold.

Abstract: Techniques for managing operation over a communication medium shared between Radio Access Technologies (RATs) are disclosed. In one example, one or more parameters of a Time Division Multiplexing (TDM) communication pattern may be set to define activated periods and deactivated periods for communication over the medium. A first interlace may be selected among a plurality of interlaces for communication over the medium, the first interlace being reserved for a first operator. During the first interlace, transmission over the medium may be cycled in accordance with the TDM communication pattern, and deactivated during a second interlace among the plurality of interlaces that is reserved for a second operator.

Abstract: Systems and methods for managing communication in an unlicensed band of frequencies to supplement communication in a licensed band of frequencies in unlicensed spectrum are disclosed. The management may comprise, for example, monitoring utilization of resources currently available to a first Radio Access Technology (RAT) via at least one of a Primary Cell (PCell) operating in the licensed band, a set of one or more Secondary Cells (SCells) operating in the unlicensed band, or a combination thereof. Based on the utilization, a first SCell among the set of SCells may be configured or de-configured with respect to operation in the unlicensed band.
