A communication system may include a base station (BS), user equipment (UE), and a set of reconfigurable intelligent surfaces (RIS's). The RIS's, the UE, and the BS may communicate using a control RAT and a data RAT. The BS may transmit downlink (DL) signals to the UE device via reflection off a DL RIS. The UE device may transmit uplink (UL) signals to the BS via reflection off a UL RIS. This may optimize wireless performance in situations where reflecting the UL and DL signals off the same RIS would limit performance under the current data RAT channel conditions. The BS and the UE device may use channel measurements of the control RAT at the RIS's to select the UL RIS and the DL RIS. This may significantly reduce overhead required to identify the UL and DL RIS's relative to scenarios where exhaustive beam training is used.

Communication via uplink and downlink reflective devices

Apparatuses, methods, and systems are disclosed for adjusting a contention window size. One apparatus includes a processor and a transceiver comprising a plurality of transmit panels. The transceiver initiates a first channel occupancy ('CO') using at least one transmit panel in response to a successful Listen-Before-Talk procedure and transmits a directional transmission using a first transmit panel, the first transmit panel selected from the plurality of transmit panels. The processor determines whether the directional transmission was successfully received by a recipient and updates a first contention window size specific to the first transmit panel. The processor performs a subsequent Listen-Before-Talk procedure using the updated first contention window size prior to a subsequent directional transmission using the first transmit panel.

Updating a contention window size

Apparatuses, methods, and systems are disclosed for receiver-assisted interference mitigation. One apparatus includes a processor and a transceiver that is operable on unlicensed spectrum, where the transceiver includes a plurality of UE panels. The processor generates a first TB for a first UL channel resource. Here, the first TB contains control signaling or data. The processor performs a directional LBT procedure for a first panel associated with the first UL channel resource and transmits request information to a RAN node using the first UL channel resource in response to successful directional LBT. The processor receives feedback information from the RAN node in response to the request information and transmits the first TB using the first UL channel resource in response to receiving the feedback information.

The present disclosure provides a transceiver device and a scheduling device, and communication methods for transceiver device and scheduling device. The transceiver device comprises a transceiver, which, in operation, transmits a scheduling request for scheduling data over a physical uplink control channel, PUCCH; and circuitry, which, in operation, initiates a monitoring sleeping timer after the transceiver transmitted the scheduling request, wherein the transceiver, in operation, does not monitor a physical downlink control channel, PDCCH, while the monitoring sleeping timer is running, and starts monitoring the PDCCH for resource allocation for the scheduling data when the monitoring sleeping timer has expired.

Transceiver device and scheduling device

A user equipment (UE) receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling; configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, each with a value indicating a PUSCH mapping type, a value K2 indicating a slot offsets, and a value SLIV indicating a start and length indicator value; and receives downlink control information (DCI) in form of medium access control (MAC) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The UE determines allocated resources for an initial PUSCH transmission and allocated resources for at least one repetition thereof, and performs a PUSCH transmission using the respectively determined allocated resources.
