(54) Title: COMMUNICATION TECHNIQUES APPLYING LOW-DENSITY PARITY-CHECK CODE BASE GRAPH SELEC- TION (57) : Certain aspects of the present disclosure generally relate to tech- niques for selecting a base graph to be used for wireless communications. Selec- tion can be based on a variety of factors. Abase graph can be used to derive a low-density parity-check (LDPC) code used for encoding a retransmission of an original transmission. An exemplary method generally includes selecting, based on a modulation and coding scheme (MCS) and a resource allocation (RA) for transmitting a codeword, a base graph (BG), from which to derive a low density parity check (LDPC) code for use in encoding data bits in the codeword (e.g., encoding data bits of a bitstream such that some redundant bits are included in the codeword), encoding the data bits to generate the codeword using the LDPC code derived from the selected BG, and transmitting the code- word using the MCS via resources of the RA.

    Abstract: RESUMEN Aspectos de la presente divulgación proporcionan un dispositivo inalámbrico que se comunica con otro dispositivo inalámbrico mediante subtramas independientes. El dispositivo inalámbrico se comunica con una entidad de programación mediante una pluralidad de subtramas independientes que incluyen una primera subtrama y una segunda subtrama. Cada una de las subtramas independientes incluye una porción de enlace ascendente (UL) y una porción de enlace descendente (DL). El dispositivo inalámbrico recibe además información de control de DL de la entidad de programación en la porción de DL de la primera subtrama, y transmite datos de UL que incluyen una pluralidad de ráfagas de la señal de referencia a la entidad de programación en la porción de UL de la primera subtrama. La pluralidad de ráfagas de la señal de referencia está espaciada de manera uniforme en al menos una porción de la porción de UL de la primera subtrama.

    Abstract: Aspects of the disclosure relate to a transmitting device, which may explicitly or implicitly signal the use of continuous precoding for a resource block (RB) cluster. For example, the transmitting device may implicitly indicate that continuous precoding is applied to an RB cluster by dynamically controlling one or more parameters of a transmission over those RBs. Further, when continuous precoding is applied to an RB cluster, the transmitting device may explicitly or implicitly signal the dynamic control over one or more transmission properties, with an aim to maximize the benefits of such continuous precoding. Other aspects, embodiments, and features are also claimed and described.

    Abstract: The connection management entity apparatus determines a set of modems within coverage of a particular area. Each modem of the set of modems is associated with a particular aircraft and one carrier of a plurality of carriers. The apparatus allocates subsets of modems to each eNB of a set of eNBs. The allocation allows each eNB to communicate with the allocated subset of modems. Each eNB operates on a different carrier. The apparatus may be a eNB. The eNB determines a set of modems within coverage of the eNB. The set of modems is associated with one carrier of a plurality of carriers. The eNB operates on the one carrier. Each modem in the set of modems is associated with a different aircraft. The eNB sends information indicating the set of modems and receives an allocation of a second set of modems in response to the sent information.

    Abstract: Techniques for assigning multipaths to finger processors to achieve the desired data performance and low power consumption are described. A search is initially performed to obtain a set of multipaths for a transmission from at least one base station. At least one multipath (e.g., the minimum number of multipaths) having a combined performance metric (e.g., a combined SNR) exceeding a threshold is identified. The at least one multipath is assigned to, and processed by, at least one finger processor to recover the transmission from the base station(s).
