Abstract: Apparatus and methods of wireless communications operating in a wideband new radio (NR) system include identifying a system bandwidth value of a cell, and identifying a user equipment (UE) bandwidth capability. Additionally, the aspects include determining a UE-specific set of bandwidth parts each having a UE-specific bandwidth based on the system bandwidth value and the UE bandwidth capability, and communicating with the cell using at least one of the UE-specific set of bandwidth parts. Further, the described apparatus and methods may enable dual-mode operations in a wideband component carrier (CC)) in the NR system.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to synchronization for standalone long term evolution (LTE) broadcast. In one aspect, a method is provided which may be performed by a wireless device such as a base station (BS). The method generally includes providing unicast coverage to one or more user equipments (UEs) in a unicast coverage area within a larger coverage area, transmitting unicast data in one or more subframes, and transmitting synchronization signals within one or more of the broadcast subframes, wherein the broadcast signals are transmitted as single frequency network (SFN) transmissions synchronized with transmissions from one or more other base stations providing unicast coverage within the larger coverage area.

Abstract: Aspects of the disclosure relate to allocating resources for a physical uplink control channel (PUCCH). In a first example, a subset of a resource set corresponding to a PUCCH is identified based on an explicit mapping of acknowledgment resource indicator (ARI) values, and a resource index corresponding to a resource within the subset is derived based on an implicit mapping of the resource index. A PUCCH communication is then transmitted via the resource. In another example, a user equipment (UE) is configured to ascertain resources for a PUCCH in accordance with an explicit mapping of ARI values and an implicit mapping of a resource index such that the explicit mapping facilitates an identification of a subset of a resource set, whereas the implicit mapping facilitates a derivation of the resource index to identify a corresponding resource within the subset.

Abstract: Aspects of the present disclosure describe receiving a first communication according to a first timeline, wherein the first timeline is based on a first cyclic prefix (CP) type, and receiving a second communication according to a second timeline, where the second timeline is based on a second CP type, and where the second communication is multiplexed with the first communication in the same slot.

Abstract: Certain aspects of the present disclosure provide techniques for carrier independent signal transmission and reception. Certain aspects provide a method for wireless communication. The method includes applying, at a device, a phase correction to a first signal to compensate for a difference between a first zero tone location comprising a first frequency and a second zero tone location comprising a second frequency. The method further includes one of: transmitting the first signal after applying the phase correction; or receiving the first signal prior to applying the phase correction.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for power control. For example, a method is provided for wireless communication by a user equipment that includes determining whether a sum of a first power limit for communicating on an uplink associated with a first radio access technology and a second power limit for communicating on an uplink associated with a second radio access technology is greater than an overall power limit for communicating on uplinks by the user equipment. The method further includes scaling down power used for a transmission on the uplink associated with the first radio access technology during the first time or dropping a transmission on the uplink associated with the first radio access technology during the first time when the sum is greater than the overall power limit.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication that includes downlink control information (DCI), wherein a size of the DCI affects a cyclic redundancy check (CRC) value associated with the communication; and determine the DCI or the size of the DCI based at least in part on the CRC value. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive remaining minimum system information (RMSI) from a base station (BS); determine an initial active uplink bandwidth part based at least in part on the RMSI; and use the initial active uplink bandwidth part for a random access channel (RACH) procedure between the UE and the BS. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while the UE is using a first modulation order for a physical uplink control channel, a signaling message that identifies a second modulation order, for the physical uplink control channel. The UE may provide the physical uplink control channel using the second modulation order. In some aspects, a base station may provide, while a UE is using a first modulation order for a physical uplink control channel, a signaling message that identifies a second modulation order, for the physical uplink control channel. The base station may receive the physical uplink control channel using the second modulation order. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques that may be used for low latency communications. For example, aspects allow a single group acknowledgement to be used to acknowledge a plurality of low latency transmissions. An exemplary method generally includes receiving, from a base station, a plurality of downlink channel transmissions, wherein each of the downlink channel transmissions is sent using a first transmission time interval (TTI) that is reduced relative to a legacy TTI and providing, in a single uplink channel transmission sent using a second TTI that is larger than the first TTI, a group acknowledgement indicating whether or not the downlink channel transmissions were successfully received by a UE.
