Abstract: Disclosed are methods and apparatus for determining time-domain PRACH resources in wireless communication. A New Radio (NR) Physical Random Access Channel (PRACH) configuration comprising an indication of a time-domain PRACH resource type to determine when the UE is allowed to transmit a PRACH preamble and a type of preamble format may be received. Additionally, a PRACH resource based on the received PRACH configuration to transmit the PRACH preamble, wherein the PRACH resource includes RACH resource occasions (ROs) with gaps in between may be determined. Thereafter, a PRACH procedure may be initiated by transmitting the PRACH preamble on a RO based on the determined PRACH resource to a base station (BS).

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for signaling cross-division duplex configurations. One of the methods includes identifying, by a first device and for a first link with a second device, a switch in a first bandwidth part to a second bandwidth part for the first link, the first link associated with a second link having a third bandwidth part; determining, by the first device, whether a bandwidth band between the second bandwidth part and the third bandwidth part satisfies a threshold guard band; and selectively determining to maintain the third bandwidth part for the second link or to switch the third bandwidth part to a fourth bandwidth part for the second link using a result of the determination whether the bandwidth band between the second bandwidth part and the third bandwidth part satisfies the threshold guard band.

Abstract: Apparatuses, systems, and methods for CCA power signaling during COT sharing. A UE may report a maximum EIRP for COT sharing as a UE capability, e.g., for a frequency range between 52.6 and 71 gigahertz. The UE may receive a Pout value for CCA based on the UE capability and may report an actual EIRP used for CCA to acquire the COT. For configured grant COT sharing, the UE may perform a directional LBT with a specific EIRP and beam detection for a transmission burst and report a Pout value for COT sharing based on the directional LBT, e.g., via a configured grant uplink control indication. For dynamic grant COT sharing, the UE may detect that an EIRP exceeds a threshold and report a Pout value for COT sharing via a medium access control (MAC) control element. The threshold may be based on a closed loop power control setting.

Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within a prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

Abstract: Methods, circuitries, and systems are disclosed for configuring multiple PDSCH/PUSCH transmission with repetition of each transmission. In one example, a method includes receiving, from a base station, control information that indicates i) time domain resources for communication of at least two physical downlink shared channel (PDSCH) or at least two physical uplink shared channel (PUSCH) transmissions and ii) at least one repetition number indicating a number of times each of the at least two PDSCH/PUSCH transmissions is repeated. The method includes configuring operation to receive the at least two PDSCH transmissions or to transmit the at least two PUSCH transmissions based on the time domain resources and repetition number.

Abstract: Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A base station can poll user equipment (UE) by transmitting a downlink control information (DCI) or other downlink communication that indicates resources that a UE can use to send a scheduling request. The resources are dynamic, e.g., they can be updated and allocated to UEs based on network conditions. Other aspects are described.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.
