Abstract: According to some examples, a base station may allocate uplink and/or downlink resources (e.g., in the time domain, frequency domain, spatial domain) to user equipment (UEs), or groups of UEs, that may be subsequently reallocated. For example, a base station may determine a reallocation of uplink resources, and may issue a preemption indication (e.g., a cancelation indication) that may correspond to at least a portion of a random access resource. UEs may be configured to monitor for preemption indications and, based on received preemption indications, UEs may determine whether or not to proceed with transmission of a random access message using a random access resource that at least partially overlaps with resources indicated by the preemption indication. For example, a UE may transmit, or preempt transmission of, a random access message based on a preemption configuration of the UE (e.g., configured rules for UE preemption of random access resources).

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may use low latency communications to improve the throughput of a wireless link. To facilitate efficient low latency communication, the UE may send UE-initiated CSI reports in addition to periodic and base station-initiated reports. For example, the UE may, in various examples, send UE-initiated CSI reports using contention based spectrum, using a request-to-transmit, or using a CSI differential (i.e., an indicator of a change in channel conditions). The base station may schedule different UEs for uplink low latency communication by providing resources to each UE for CSI and scheduling requests (SRs) using coherent or non-coherent uplink transmissions. The CSI and SR may also be combined with uplink feedback.

Abstract: Techniques are described for wireless communication. A first method includes generating uplink control information at a wireless device, and transmitting the uplink control information over an interlace of a component carrier of an unlicensed radio frequency spectrum band. The interlace includes a plurality of non-contiguous concurrent resource blocks in the unlicensed radio frequency spectrum band, and at least two resource blocks in the interlace include different portions of the uplink control information. A second method includes generating uplink control information at a wireless device, and transmitting the uplink control information over an uplink control channel of an unlicensed radio frequency spectrum band. Resources of the uplink control channel are divided into a plurality of discrete dimensions and the uplink control information of the wireless device is transmitted over a number of the discrete dimensions allocated to the uplink control information of the wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that signaling associated with a resource allocation is associated with a service type. The UE may identify a time-domain resource, for a transmission associated with the service type, in connection with determining that the signaling associated with the allocation is associated with the service type. Numerous othNo errors found.er aspects are provided.

Abstract: Aspects of the present disclosure provide techniques that may be applied in systems to allow for communication over a control channel utilizing a relatively narrow band (e.g., six physical resource blocks) based search space. An exemplary method, performed by a user equipment, generally includes identifying, within a subframe, a first search space to monitor for a downlink control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband size and monitoring at least the first search space for the downlink control channel transmitted in the subframe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: This disclosure provides systems, methods and apparatus for assisting a user equipment (UE) with balancing quality of service (QoS) requirements (such as access latency or reliability requirements) and consumption of high priority network resources (such as for load balancing) when transmitting a random access message (RAM) in a two-step random access channel (RACH) procedure. As a result, the UE may be capable of satisfying QoS requirements for the RAM while reducing an impact of transmission of the RAM on other uplink transmissions. Furthermore, some techniques and apparatuses described herein assist a UE with prioritizing portions of the RAM in different UE operating modes, such as a dual connectivity mode, a carrier aggregation mode, or a supplemental uplink mode. Some techniques and apparatuses described herein employ cross-carrier scheduling, dynamic power sharing, or dynamic power control to achieve these and other performance improvements.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for enabling a wireless system implementing multicast transmissions to control feedback reports from multiple user equipments (UEs) and to address feedback codebook misalignment issues. In particular, aspects provide for multicast transmission grants including multiple feedback timing indicators (K1) in which the multicast transmission grants are configured to configure different UEs for multicast transmission feedback reporting in which feedback codebooks transmitted in various uplink control transmission occasions from the different UEs have a same size. Other aspects and features are also claimed and described.

Abstract: Comb adaptation for interlaced frequency division multiplex (IFDM) demodulation reference signals (DMRS) is discussed. Transmission configuration for DMRS may be assigned to UEs with a coded combination of cyclic shift, OCC, and comb value. Some assigned combinations provide for a different comb value to be used for the different slots in the same subframe. Further aspects provide additional interference randomization through comb shifting, using inter-subframe hopping functions. Additionally, where retransmissions are present without uplink grant, the UE may select comb values for retransmissions based on the counter number for the retransmissions, which are different than the comb values used for the original DMRS transmissions.
