摘要： Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a plurality of resource blocks of a short channel mapped using a short resource element group (sREG) to short control channel element (sCCE) mapping. The short channel may be a short physical downlink control channel (sPDCCH) or a short physical downlink shared channel (sPDSCH). The wireless communication device may process the short channel using the plurality of resource blocks. The plurality of resource blocks may be bundled into a set of resource block bundles based at least in part on the sREG-to-sCCE mapping.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may identify a potential collision between a scheduled legacy transmission time interval (TTI) communication and a scheduled shortened TTI (sTTI) communication, the legacy TTI communication having a legacy TTI duration that is longer than an sTTI duration associated with the sTTI communication. The apparatus may determine whether the legacy TTI communication is within a threshold time of being transmitted. The apparatus may transmit at least one of the sTTI communication, the legacy TTI communication, or any combination thereof, based at least in part on the determination.

摘要： Aspects of the present disclosure describe communicating control data based on reference signals in wireless communications. A timeline for transmitting uplink communications can be determined, where the timeline can relate to whether to process downlink communications based on at least one of a first type of reference signal (RS) or a second type of RS, a length or number of symbols in the reference signal, or a timing advance.

摘要： In an aspect, an apparatus may receive content to be transmitted and generate a first turbo encoded codeword from the content through use of a first turbo encoder. The apparatus maybe further configured to generate an interleaved codeword based on the first turbo encoded codeword through use of an interleaver, generate a second turbo encoded codeword from the interleaved codeword through use of a second turbo encoder, and transmit at least a portion of the second turbo encoded codeword. In an aspect, an apparatus may receive data including outer turbo encoded, interleaved, inner turbo encoded content. The apparatus may generate a first decoded instance of the data, generate a de-interleaved instance of the data based on the first decoded instance of the data, generate a second decoded instance of the data from the de-interleaved instance of the data, and perform a CRC on the second decoded instance of the data.

摘要： The present disclosure may enable a buffer to accommodate HARQ processes for transmissions with different TTIs when the UE is configured for legacy communications and ULL communications. The apparatus may allocate a first number of HARQ IDs to a first portion of a buffer, the first number of HARQ IDs being associated with a first transmission TTI HARQ process. In addition, the apparatus may allocate a second number of HARQ IDs to a second portion of the buffer. In an aspect, the second number of HARQ IDs may be associated with a second TTI HARQ process. In addition, the first portion and second portion may not change a total buffer size. The apparatus may also receive a HARQ response associated with a HARQ ID allocated to the first portion or the second portion.

摘要： The present disclosure provides a unique control region that is mapped to each data region for DL DMRS transmissions. In addition, the present disclosure provides an updated DCI format that may include DL DMRS transmissions. The apparatus may receive a first content during a first TTI. In an aspect, the content may include at least a control region which includes a DMRS. In addition, a location of the DMRS may be defined by either a closed-loop precoding structure or an open-loop precoding structure. Furthermore, the duration of the first TTI may be shorter than 1 ms. The apparatus may demodulate the control region based at least on the DMRS.

摘要： Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). An example method generally includes identifying a plurality of slots in a subframe, receiving a resource configuration for an uplink channel, wherein the resource configuration is associated with a first slot of the plurality of slots, determining a resource for transmitting the uplink channel in a second slot of the plurality of slots, wherein the resource is determined based on the resource configuration associated with the first slot of the plurality of slots, and transmitting the uplink channel in the second slot using the determined resource.

摘要： Techniques are provided for sidelink aided time difference of arrival (TDOA) based positioning methods. An example method of determining a time difference of arrival value includes receiving a first reference signal at a first time, wherein the first reference signal is transmitted from a first wireless node using a first radio access link, receiving a. second reference signal at a second time, wherein the second reference signal is transmitted from a second wireless node using a second radio access link, receiving assistance data including at least a transmit delay time value based, on a time the first reference signal is received by the second wireless node, and a time the second reference signal is transmitted by the second wireless node, and determining the time difference of arrival value based at least in part on the first time, the second time and the transmit delay time value.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink communication. The UE may receive a configuration identifying a first uplink resource for a hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second uplink resource for multiplexing channel state information (CSI) reports. The UE may receive a downlink communication. The UE may determine that a HARQ-ACK for the downlink communication is to be multiplexed with one or more CSI reports on the second uplink resource. The UE may determine that an error has occurred based at least in part on a determination that the second uplink resource configured is in a different sub-slot than the first uplink resource. Numerous other aspects are provided.

摘要： A network node of a first radio access technology (RAT) may configure, from a set of resources available for dynamic spectrum sharing between the first RAT and a second RAT, a first subset of resources on which to communicate with one of rate matching or spatial domain multiplexing associated with the second RAT. A UE may receive, from a network node associated with the first RAT, information indicating a first subset of resources from a set of resources available for dynamic spectrum sharing between the first RAT and a second RAT with one of rate matching or spatial domain multiplexing. The network node and the UE may communicate on the first subset of resources from the set of resources with the one of rate matching or spatial domain multiplexing.
