Abstract

SUB-SLOT GROUPING CONFIRMATION A first device may punch, in at least two sub-slots, a first type of control information or data with a second type of control information or data. The first device may group the at least two sub-slots within a subframe, and the subframe may include a portion to carry acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of control information or data. The first device may communicate with a user equipment (UE) during the at least two sub-slots within the subframe. A second device may receive ACK/NACK information associated with a second type of control information or data. The second device may reduce a transmission power for a first type of control information or data during the subsequent subframe when the ACK/NACK information indicates a negative acknowledgment.

Description

CROSS-REFERENCE TO RELATED REQUEST(S) [001] This application claims the benefit of U.S. Provisional Application Serial No. 62/435,518, entitled "SUBSLOT BUNDLING AND ACKNOWLEDGEMENT," filed December 16, 2016, and U.S. Patent Application No. 15/789,489, entitled "SUBSLOT BUNDLING AND ACKNOWLEDGEMENT," filed October 20, 2017, which are expressly incorporated by reference herein in their entirety. BACKGROUND Field [002] The present disclosure relates generally to communication systems, and more particularly to a base station configured to group sub-slots. Background [003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users through the sharing of available system resources. Examples of such multiple access technologies include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA), orthogonal frequency division multiple access systems (OFDMA), single carrier frequency division multiple access systems (SC-FDMA), and synchronous time division code division multiple access systems (TD-SCDMA). [004] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at a municipal, national, regional, and even global level. An exemplary telecommunications standard is Long Term Evolution (LTE). LTE is a set of improvements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). LTE is designed to support mobile broadband access through improved spectral effectiveness, reduced costs, and enhanced services with the use of OFDMA in the downlink, SC-FDMA in the uplink, and multiple-input multiple-output (MIMO) antenna technology. However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in LTE technology. These improvements may also be applicable to other multiple access technologies and the telecommunications standards that employ these technologies. [005] An example of an enhancement to LTE could include fifth-generation (5G) mobile networks and wireless systems. 5G is a telecommunications standard that can extend beyond LTE and/or 4G standards. For example, 5G can offer superior capacity and therefore serve a larger number of users in an area. Furthermore, 5G can improve data consumption and data rates. SUMMARY [006] The following is a simplified summary of one or more aspects to provide a basic understanding of such aspects. This summary is not an extensive overview of all aspects covered, and is not intended to identify key or critical elements of all aspects or to delimit the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified way as a prelude to the more detailed description that is presented later. [007] In one aspect of the disclosure, a first method, a first computer-readable medium, and a first apparatus are provided. The first apparatus may punch, in at least two subpartitions, a first type of control information or data with a second type of control information or data. The first apparatus may group the at least two subpartitions within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of control information or data. The first apparatus may communicate with a user equipment (UE) during the at least two subpartitions within the subframe. [008] In another aspect of the disclosure, a second method, a second computer-readable means, and a second device are provided. The second device can receive ACK/NACK information associated with a second type of control information or data. The second device can reduce transmission power for a first type of control information or data during the subsequent subframe when the ACK/NACK information indicates a negative acknowledgment. [009] In another aspect of the disclosure, a third method, a third computer-readable means, and a third device are provided. The third device may receive a second type of control information or data carried in at least two subpartitions grouped within a subframe, and the second type of control information or data may be punched into a first type of control information or data. The subframe may include a portion for carrying ACK/NACK information associated with the second type of control information or data. The third device may determine ACK/NACK information for the second type of control information or data carried in at least two subpartitions grouped within a subframe, and the third device may send the ACK/NACK in
