Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify that a last resource block of a resource allocation for a physical downlink shared channel (PDSCH) is in a last allocable resource block group (RBG); and determine whether one or more additional resource blocks, subsequent to the last resource block, are included in the resource allocation for the PDSCH based at least in part on at least one of a reference signal type associated with the PDSCH, a quantity of the one or more additional resource blocks, or the DCI format associated with the PDSCH. Numerous other aspects are provided.

Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.

Abstract: Various aspects of the disclosure provide a method of operating a user equipment (UE) to determine and report a throughput enhancing channel quality indicator (CQI) value when a physical channel between the UE and a base station is temporally uncorrelated. Reporting such CQI value may maximize the throughput of the channel when it remains temporally uncorrelated. In one aspect of the disclosure, the UE communicates with a base station utilizing a channel and determines that the channel is temporally uncorrelated. The UE further determines a plurality of CQIs in a first CQI reporting mode and computes the respective throughputs of the channel based on the plurality of CQIs. In addition, the UE selects a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs, and reports the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.

Abstract: Methods, systems, and devices for wireless communications are described. More specifically, the methods, systems, and devices support extending capability signaling to support higher modulation order baseband capability, such as higher order quadrature amplitude modulation (QAM), for example, 1024QAM. By way of example, a user equipment (UE) may transmit UE capability information to a base station (e.g., eNodeB (eNB), next-generation NodeB ((gNB)) in a connection establishment procedure. The UE capability information may include a UE category identifier and a baseband capability parameter. The baseband capability parameter may indicate a scaling factor for a first modulation order of a plurality of available modulation orders. The UE may communicate with the base station over multiple layers using corresponding modulation orders for the multiple layers.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, base stations may transmit downlink transmissions in short transmission time intervals (sTTIs) shorter than 1 millisecond (ms) transmission time intervals (TTIs). The base stations and user equipment (UE) receiving the downlink transmissions may be configured to determine a transport block size, soft channel bit buffer size, or rate matching based on the sTTI. The transport block size may be selected based on a scaling factor associated with signaling overhead or a type, length, or index of sTTI, or based on an sTTI transport block size table. The buffer size may be selected based on scaling or not scaling a buffer size value, N_IR, associated with a TTI. Additionally, UEs may handle receiving retransmissions of downlink transmissions in different length TTIs, and base stations may select channel quality indicator-to-modulation and coding scheme mappings on an sTTI-by-sTTI basis.

Abstract: The present disclosure describes a method and an apparatus for pruning false peaks during slot synchronization at a user equipment (UE). For example, a method is provided to identify a plurality of first peaks associated with a primary-synchronization channel (P-SCH) received at the UE and a plurality of second peaks from the plurality of first peaks. Further, one or more pruning locations along with associated energy thresholds for each of the plurality of the second peaks may be determined and whether a peak of the plurality of the first peaks is a false peak is identified based on whether the peak is located at one of the one or more pruning locations of the peak and an associated energy value of the peak does not satisfy the associated energy threshold of the pruning location. Furthermore, the peak identified as the false peak is discarded.

Abstract translation: 本公开的各个方面提供了当UE和基站之间的物理信道在时间上不相关时操作用户设备（UE）以确定和报告吞吐量增强信道质量指示符（CQI）值的方法。 报告这样的CQI值可以使信道的时间上不相关的吞吐量最大化。 在本公开的一个方面，UE利用信道与基站进行通信，并确定信道在时间上不相关。 UE进一步在第一CQI报告模式中确定多个CQI，并且基于多个CQI来计算信道的相应吞吐量。 另外，UE在多个吞吐量中选择对应于最高吞吐量的多个CQI的CQI，并且在第二CQI报告模式中将所选择的CQI报告给基站，同时信道保持在时间上不相关。
