Abstract: Aspects of the disclosure relate to implied and explicit mapping of uplink (UL) resources for acknowledgment communications from a user equipment (UE). In some examples disclosed herein, implied mapping may include indexing of information elements in a downlink (DL) communication. The explicit mapping may include information elements in the DL communication configured to explicitly provide a location of an UL resource. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure provide techniques and apparatus for performing paging and/or random access procedures with multiple physical resource blocks (PRBs) for narrowband (NB) internet-of-things (IoT). In one aspect, a method is provided which may be performed by a base station. The method generally includes determining a first set of resources and a second set of resources available for narrowband communications with one or more first user equipments (UEs) and one or more second UEs. The method also includes allocating the first and second set of resources to one or more of the first UEs and the second UEs based at least in part on a type of the first UEs and a type of the second UEs. The method further includes signaling an indication of the allocation.

Abstract: Aspects of the present disclosure provide various hybrid automatic repeat request (HARQ) retransmission indication schemes used in a HARQ retransmission process. The HARQ retransmission indication can implicitly or explicitly indicate which part of a transport block (TB), code block group(s), or code block(s) is/are being retransmitted so that the receiver can associate the retransmitted TB, code block group(s), code block(s) with the correct prior reception, for example, for HARQ combining purposes

Abstract: Aspects of the present disclosure relate to techniques for non-codebook based UL transmission. In some cases, a UE may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.

Abstract: Aspects of the present disclosure provide a code block group (CBG) based HARQ retransmission process in which HARQ retransmission is performed based on CBG units. The CBG based HARQ process uses a CBG failure mask that can reduce the signaling overhead of CBG-based HARQ retransmissions. A base station can determine the error CBGs from different UEs that share a slot, and generate a CBG failure mask that capture all the CBGs NACKs from the UEs.

Abstract: NB wireless communication involves numerous challenges. A limited frequency dimension may need to be shared by multiple users. At times, large data transmissions, including multiple TBs of data may be transmitted using NB communication, and it may be important that each TB be successfully received by the users. The apparatus may transmit data comprising a plurality of TBs in a narrow band communications system, including repeating a transmission of the plurality of TBs, using any of a number of repetition patterns. The apparatus may use error correction encoding across multiple TBs. The transmission may be a single cell transmission or a multi-cell transmission.

Abstract: Aspects of the present disclosure provide techniques for managing unwanted transmissions by a wireless communications device, such as spurious transient transmissions caused by changing a power level of a transmitter. An exemplary method includes determining, based on one or more parameters, an action to reduce an impact of a spurious transmission by the UE, wherein the spurious transmission relates to at least one of changing a transmit power level at the UE or switching one or more radio components at the UE, and taking the determined action to reduce the impact.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to enhanced paging procedures for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced or evolved MTC (eMTC) devices. An example method generally includes determining a set of subframes corresponding to a paging occasion for the UE to receive a paging message from a base station (BS), determining, within the set of subframes, at least one narrowband region for receiving the paging message, and monitoring for the paging message in the at least one narrowband region within the set of subframes.
