Abstract: A first uplink channel is obtained to carry joint information of second uplink control information carried on a second channel and third uplink control information carried on a third uplink channel. In response to the first and third uplink channels meeting a first condition, the joint information is sent on the first uplink channel. Otherwise, the third uplink control information is sent on the third uplink channel. The first condition includes at least one of: (i) a distance between ending symbols on the first and third uplink channels is less than or equal to a first threshold, (ii) a distance between starting symbols on the first and third uplink channels is less than or equal to a second threshold, or (iii) a difference between coding rates of the first and third uplink channels is less than or equal to a third threshold.

Abstract: Embodiments of this disclosure provide techniques for signaling in power save mode. In particular, a UE may identify an association between a set of time durations for paging a downlink control indicator (DCI) transmission and a wake up signal (WUS) in a set of WUSs. Paging the DCI is transmitted in a beam sweeping manner and each beam used in each time duration in the set of time durations corresponds to a respective beam used for a WUS transmission in the set of WUSs. The UE monitors a radio link quality of WUSs in the set of WUSs and, based thereon, selects a first WUS in the set of WUSs. The UE identifies a first time duration for DCI page monitoring, the first time duration corresponding to the first WUS. The UE monitors the DCI page during the first time duration.

Abstract: An image coding mechanism is disclosed. The mechanism includes determining a region of interest in an image. The image is partitioned into a plurality of blocks. A transform is applied to the blocks to obtain a plurality of coefficients. The coefficients are assigned into quality layers of decreasing priority. Each subsequent layer includes data to incrementally increase quality of a reconstructed image. Region of interest coefficients are positioned in one or more image data packets by quality layer in order of decreasing priority. Remaining coefficients are positioned in the image data packets with a lower priority than the region of interest coefficients. The remaining coefficients are positioned by quality layer in order of decreasing priority. The image data packets are stored and transmitted over a network.
