    Abstract: Techniques and apparatus are provided for conditional offload of one or more LLRs or decoded bits. An exemplary electronic device (ED) method includes receiving a transmission of a physical downlink shared channel (PDSCH) having a transport block (TB) comprising at least one code block (CB), performing a cyclic redundancy check (CRC) of the at least one CB, in a memory external to a modem core of the ED, storing a subset of log-likelihood ratios (LLRs) associated with the at least one CB if the at least one CB failed the CRC or decoded bits associated with the at least one CB if the at least one CB passed the CRC, wherein the subset is based on an LLR range of the transmission relative to an LLR range of one or more previous transmissions, and using the stored subset of LLRs or decoded bits to process a re-transmission of the PDSCH.

    Abstract: Methods, systems, and devices for wireless communications are described. Efficient low-density parity-check (LDPC) scheduling of layered decoding may include receiving a message encoded as an LDPC code that includes a number of check nodes and a number of bit nodes, applying a first number of decoding iterations to decoding the message, applying a second number of decoding iterations to decoding the message after the first number of decoding iterations are applied, and decoding the message through completion of both the first number of decoding iterations and the second number of decoding iterations. In some cases, only a portion of the number of check nodes is decoded during each of the first number of decoding iterations and all of the number of check nodes are decoded during each of the second number of decoding iterations.

    Abstract: Power consumption by a communication satellite may be reduced by operating in a transmission time interval (TTI) gating mode, in which an on period is provided for the satellite to transmit a reference signal (RS), control signals, and a portion of data within an on period through a forward link to a user terminal (UT), followed by an off period in which forward link transmission ceases. During the off period of the TTI, the satellite may turn off its forward link power amplifier and cease transmission of data to the UT. A gateway may send a signal enabling the TTI gating mode, as well as information specifying the TTI gating configuration, such as the length of the on or off period of the TTI, to the satellite.

    Abstract: In a transmission scheme wherein multi-slot packet transmissions to a remote station can be terminated by an acknowledgment signal from the remote station, code symbols can be efficiently packed over the multi-slot packet so that the remote station can easily decode the data payload of the multi-slot packet by decoding only a portion of the multi-slot packet. Hence, the remote station can signal for the early termination of the multi-slot packet transmission, which thereby increases the data throughput of the system.

    Abstract: Embodiments disclosed herein relate to methods and systems for pilot grouping, route protocols, and scheduling in multi-carrier communication systems. In an embodiment, an access terminal may group a plurality of pilot signals characterized by different frequencies into one or more pilot groups, each pilot grouping being identified by a plurality of parameters (e.g., a PN offset and a group ID). Each pilot group may include pilot signals having substantially the same coverage area. The access terminal may further select a representative pilot signal from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping for effective set management.
