Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant associated with a plurality of physical shared channel resources.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a configuration of a common PUCCH resource set that is based on a frequency hopping pattern and includes a first set of resource blocks (RBs) of a bandwidth part (BWP) in a first group of symbols and a second set of RBs of the BWP in a second group of symbols. In some designs, the second set of RBs is offset in frequency from the first set of RBs by a fixed hopping distance. In other designs, the BWP is further associated with a second PUCCH resource set that includes a third set of RBs of the BWP that overlaps in part with the first set of RBs of the BWP in the first group of symbols, a fourth set of RBs of the BWP that overlaps in part with the second set of RBs of the BWP in the second group of symbols, or a combination thereof.

Abstract: Indication of transmission priority class is disclosed for sharing a base station's maximum channel occupancy time (MCOT) for use in autonomous uplink (AUL). Aspects of the disclosure provide for implicitly sharing the MCOT by providing an indication of transmission opportunity (TxOP) length. A serving base station sends an indication of a current TxOP length in control signals to a user equipment (UE). The UE may then infer a set of potential transmission priorities used by the serving base station according to the TxOP length, as TxOP length may relate to the MCOT, which itself may be associated with a particular transmission priority class. The UE may then, conservatively, select the highest transmission priority of the set of potential transmission priorities for autonomously transmitting any uplink data having at least the selected highest transmission priority within configured AUL resource of the current TxOP.

The method generally includes determining a PUCCH resource from the PICCH resource set and transmitting the PUCCH transmission using the PUCCH resource.

Afterwards, the base station sends to the UE a second portion of the downlink control information including parameters for one of the downlink data transmissions. The base station may also send the UE a third portion of the downlink control information including additional parameters for the downlink data transmission. After the UE obtains the portions, the UE decodes the one of the downlink data transmissions indicated at least in part by the first and second portion of the downlink control information.
