Abstract: Certain aspects of the present disclosure relate to techniques for reducing the decoding complexity for low cost devices (e.g., low cost UEs). One technique may include simplifying the PDCCH format. This may include generating a compact DCI format for transmitting DCI to a low cost device. The compact DCI format may correspond to at least one standard DCI format used by a regular UE and may comprise a reduced number of bits when compared to the standard DCI format. Another technique may include reducing the number of blind decodes. This technique may include selecting a set of resources for transmitting DCI from a limited set of decoding candidates, such that a receiving low cost device need only perform blind decodes for the limited set of decoding candidates.

Abstract: Techniques for reporting channel state information (CSI) for multiple cells (e.g., carriers) using multiple control channel formats are disclosed. A user equipment (UE) may be configured for operation on a plurality of cells. The UE may be configured to periodically report CSI for the plurality of cells and may also report CSI whenever requested. The UE may be configured with a plurality of control channel formats for sending CSI and possibly other control information in different subframes. The plurality of control channel formats may be associated with at least two different capacities. The UE may report CSI for the plurality of cells in the plurality of subframes based on the plurality of control channel formats.

Abstract: An enhanced physical downlink control channel (e-PDCCH) may provide carrier aggregation (CA) enhancements, help support new carriers which may not be backwards compatible, reduce control channel capacity limitations of coordinated multipoint (CoMP) transmissions, and enhance DL MIMO. In wireless communication networks, such as Long Term Evolution (LTE), user equipments (UEs) may monitor both a common search space and a UE-specific search space in a control region. A search space may comprise a set of channel control element (CCE) locations where a UE may find its PDCCHs. One or more CCEs are used to transmit each PDCCH. Certain aspects provide methods and apparatus for determining a search space comprising a subset of CCEs located on a band edge of available frequency resources, and performing a search of the search space to decode at least one PDCCH.

Abstract translation: 增强的物理下行链路控制信道（e-PDCCH）可以提供载波聚合（CA）增强，帮助支持可能不向后兼容的新载波，减少协调多点（CoMP）传输的控制信道容量限制，并增强DL MIMO。 在诸如长期演进（LTE）的无线通信网络中，用户设备（UE）可以监视控制区域中的公共搜索空间和UE特定搜索空间。 搜索空间可以包括UE可以找到其PDCCH的一组信道控制元素（CCE）位置。 一个或多个CCE用于发送每个PDCCH。 某些方面提供了用于确定搜索空间的方法和装置，所述搜索空间包括位于可用频率资源的频带边缘上的CCE的子集，以及执行所述搜索空间的搜索以解码至少一个PDCCH。

In some aspects, a user equipment (UE) may receive, from a base station, a first configuration for a physical uplink control channel (PUCCH) resource set, the first configuration associated with a first configured number of symbols for a PUCCH. The UE may receive, from the base station, an indication of a number of symbols to be used for transmitting the PUCCH, the indicated number of symbols being different from the first configured number of symbols. The UE may transmit the PUCCH using the indicated number of symbols. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.

Abstract: A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.
