摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may establish narrowband communications. The base station may configure positioning reference signal (PRS) resources based at least in part on wideband or narrowband transmissions, and a UE may receive the PRS transmissions over one or more narrowband regions. The UE, may determine PRS resources and receive portions of wideband PRS transmissions that are transmitted in one or more narrowband regions of the system bandwidth. The base station may configure PRS resources separately for narrowband devices, such as according to a bandwidth of the narrowband devices or with a single PRS tone per symbol compared to two PRS tones per symbol that may be used for wideband PRS transmissions. The base station may perform positioning measurements for a UE based at least in part on timing of uplink transmissions from the UE.

摘要： The apparatus enables pilot signals, whether single tone or multiple tone, that achieve a very low PAPR. After receiving an allocation for multiple tones, the apparatus determines a pilot signal for transmission. The apparatus may select tones from the allocation for transmission of a pilot signal based on a pilot pattern. The pilot pattern may comprise a tone sequence that identifies a sequences of tones, wherein each tone in the tone sequence of identifies one tone of multiple tones for transmission of a pilot signal during a given pilot symbol period. The pilot signal may also comprise a signal sequence. The apparatus may generate a set of multi-tone modulated pilot sequences, select a pilot sequence based on a cross-correlation property, and transmit a pilot signal using multiple tones of the allocation using the selected pilot sequence.

摘要： Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.

摘要： Disclosed are techniques for communication. In an aspect, a first UE determines information (e.g., from an external device, or via the first UE's own energy sensing) associated with scheduled uplink transmissions on a set of symbols by a second UE. The first UE performs measurements on at least some of the scheduled uplink transmissions during a first subset of the set of symbols where no DL signals are received by the first UE. The first UE receives at least one DL signal during a second subset of the set of symbols, and mitigates interference associated with the at least one DL signal based on the measurements.

摘要： Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a physical uplink control channel (PUCCH) transmission is associated with a first type of service or a second type of service, wherein the second type of service is associated with a higher reliability or a lower latency than the first type of service. The UE may transmit the PUCCH transmission using a first set of resources when the PUCCH transmission is associated with the first type of service or using a second set of resources when the PUCCH transmission is associated with the second type of service. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.

摘要： 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.
