Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, a broadcast message that indicates a plurality of occasions for a control resource set, wherein the plurality of occasions are associated with a plurality of component carriers that are associated with an unlicensed band; and monitor at least one of the plurality of occasions for the control resource set. In some aspects, a user equipment may receive, from a base station, a control message that indicates a plurality of occasions for at least one control resource set, wherein the plurality of occasions are associated with a plurality of component carriers that are associated with an unlicensed band; and monitor at least one of the plurality of occasions for the at least one control resource set. Numerous other aspects are provided.

Systems, methods, apparatuses, and computer program products for user equipment (UE) power saving utilizing resource block (RB)-sets are provided.

Provided are at least a method and apparatus to perform sending, by a user equipment, towards a network node of a communication network a gap request or receiving, by a network node, from a user equipment of a communication network a gap request, wherein the gap request comprises user equipment information indicating at least one flag indicating that the user equipment can be configured to skip at least one gap occurrence, based on whether at least one of a predefined condition or at least one condition provided by the communication network is met; and communicating information comprising a gap configuration along with conditions for determining whether the network node and the user equipment should be configured to skip at least one gap occurrence based on whether at least one of a predefined condition or at least one condition provided by the communication network is met.

Wireless communications systems and methods related to providing frequency diversity for communications in an unlicensed spectrum are provided. A first wireless communication device communicates, with a second wireless communication device, an opportunistic frequency-switching configuration for a first frequency band and a second frequency band. The first frequency band and the second frequency band are shared by a first network operating entity and a second network operating entity. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first frequency band based on the opportunistic frequency-switching configuration. The first wireless communication device switches from the first frequency band to a second frequency band based on the opportunistic frequency-switching configuration. The first wireless communication device communicates, with the second wireless communication device after the switching, a second communication signal in the second frequency band based on the opportunistic frequency-switching configuration.

A method for UE capability signaling to support enhancements on resource allocation for Physical Downlink Control Channel (PDCCH) candidate monitoring in NR-U is proposed. A UE transfers UE capability information to a mobile communication network. The UE capability information includes information indicating whether the UE supports Control Resource Set (CORESET) configuration with a Resource Block (RB) offset. The UE receives resource allocation configuration of an unlicensed cell from the mobile communication network. The UE monitors PDCCH candidates on the unlicensed cell according to the resource allocation configuration.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may connect with a base station over a set of component carriers according to a carrier aggregation configuration. The UE may then monitor a search space configured for scheduling multiple component carriers and may receive downlink control information (DCI) based on monitoring the search space. The DCI may include a carrier indicator field (CIF) and may schedule a set of data transmissions over two or more component carriers (e.g., from the set of component carriers). The UE may determine that the two or more component carriers include the first component carrier and the second component carrier based on the monitored search space, the CIF within the DCI, or both. The UE may then transmit and receive the set of data transmissions over the first and second component carriers.

Some aspects described herein relate to configuring user equipment (UE) for transmitting sidelink communications. A sidelink grant for transmitting sidelink communications over multiple contiguous subchannels across multiple resource block (RB) sets in a slot can be received. A listen-before-talk (LBT) procedure can be performed over the multiple RB sets in the slot. Sidelink communications can be transmitted to one or more other UEs in the multiple contiguous subchannels across at least a subset of the multiple RB sets in the slot for which the LBT procedure succeeds

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for cross-carrier sidelink channel state information (CSI) reporting. One aspect provides a method for wireless communication by a first user equipment (UE). The method generally includes transmitting, to a second UE, one or more channel state information (CSI) requests on one or more first component carriers (CCs), via one or more sidelink control informations (SCIs) that includes a CSI request flag and receiving, in response to the one or more CSI requests, one or more CSI reports from the second UE on one or more second CCs.

Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.

A user equipment includes circuitry which selects a random access preamble sequence, and a transmitter which transmits the random access preamble sequence to a base station in a frequency bandwidth of an unlicensed band, and performs at least one of a first operation and a second operation. In the first operation, the circuitry selects a first sequence as the random access preamble sequence, the first sequence having a length longer than a length of a random preamble sequence used for a licensed band, and the transmitter transmits the first sequence in the frequency bandwidth of the unlicensed band. In the second operation, the circuitry selects a second sequence as the random access preamble sequence, the second sequence having a length equal to the length of a random preamble sequence used for the licensed band, and the transmitter transmits the second sequence with repetitions in the frequency bandwidth of the unlicensed band.
