Abstract: Idle mode power consumption reduction in wireless communications. Within a wireless communication device that is operative to communicate with any one of a number of servicing cells, paging broadcasts from more than one of these servicing cells are received and undergo only a limited amount of processing before being stored for use in subsequent processing that may be performed later. This partitioned processing allows the turning off of certain components that are not needed and/or no longer needed for determining the system frame numbers associated with various servicing cells to effectuate timing synchronization. Certain modules within such a wireless communication device may perform processing using the full capabilities of the wireless communication device to generate initially processed signal, and then after such signals are stored, then only partial processing capability of the wireless communication device may be employed, even though perhaps being slower, to complete the processing.

Abstract: A baseband processing module of a base station includes a Turbo decoding module. The Turbo decoding module decodes a Turbo code word to produce one or more Media Access Control (MAC) packet(s) carried by the turbo decode word. Each MAC packet includes a MAC packet header and the MAC packet payload, which carries one or more Radio Link Control (RLC) Packet Data Units (PDUs). The Turbo decoding module decodes the MAC packet header to determine boundaries of the PDUs carried in the MAC packet payload. The Turbo decoding module decodes RLC PDU headers and RLC PDU payloads of the RLC PDUs. The Turbo decoding module writes the decoded MAC packet header, the decoded RLC PDU headers, and the decoded RLC PDU payloads to memory in a word-aligned format. The Turbo decoding module may also operate in various other Turbo decoding modes.

Abstract: Systems and methods of handling satellite channel and LTE coexistence are provided. A first device can identify at least one first frequency band. The first device can determine that at least one second frequency band of a plurality of second frequency bands overlaps with the at least one first frequency band. In response to determining that the at least one second frequency band overlaps with the at least one first frequency band, the first device transmits a message including an identifier of the first device and an indication of the at least one second frequency band to a second device. The second device receives the message. The second device, in response to receiving a channel request from the first device, allocates, from the plurality of second frequency bands, a second frequency band different from the at least one second frequency band.

Abstract: In some aspects, the disclosure is directed to methods and systems for dense small cell deployment. In one or more embodiments, a plurality of small cells is grouped into a first group of small cells having a first power level and a second group of small cells having a second power level. In one or more embodiments, each power level in the first set of power levels is greater than each power level in the second set of power levels. In one or more embodiments, the small cells of the first group performs frequency domain inter-cell interference coordination (ICIC) between the small cells of the first group. In one or more embodiments, the small cells of the second group performs time domain ICIC with the small cells in the first group. In one or more embodiments, the small cells of the first group use a same almost blank subframe (ABS) pattern.
