摘要： Techniques for transmitting data in a wireless communication system are described. Physical channels to be sent in a super-frame are identified and allocated time slots in the super-frame. The coding and modulation for each physical channel are selected based on its capacity. The data for each physical channel is selectively encoded based on an outer code rate, e.g., for a Reed-Solomon code, and further encoded based on an inner code rate, e.g., for a Turbo code. The encoded data for each physical channel is mapped to modulation symbols based on a selected modulation scheme. The modulation symbols for each physical channel are further processed (e.g., OFDM modulated) and multiplexed onto the time slots allocated to the physical channel. Data to be sent using another radio technology (e.g., W-CDMA) is also processed and multiplexed onto time slots allocated for this radio technology.

摘要： Systems and methodologies are described herein that facilitate a centralized structure for managing multi-radio coexistence for a mobile device and/or other suitable device(s). As described herein, a control plane coexistence manager (CxM) entity and/or a data plane CxM entity can be implemented to directly interact with a set of associated transceivers (e.g., radios, etc.) in order to manage conflicts between events corresponding to the transceivers. Further, CxM operation can be divided between the control and data planes such that the control plane handles configuration and long-term operations such as radio registration, sleep mode management, long-term event resolution, interaction with upper layers, etc., while the data plane handles short-term operations with respect to radio event management based on incoming notifications or event requests. For instance, the data plane can evaluate a set of requested events, select event(s) to be executed, and provide responses to the associated transceivers relating to the selection(s).

摘要： Prior to implementing a coexistence solution for a multi-radio device, a measurement determines whether interference experienced by one radio is caused by another radio on the device. This determination includes comparing measurements of the first radio during times when the other radio is operational and when the other radio is inactive. If the compared performance measurements are within a certain range, a coexistence/interference management solution may be implemented.

摘要： A method of wireless communication includes determining denial rates for first and second communication attempts of a packet using a first communication resource (e.g., an LTE radio). The method also includes allowing a second communication resource (e.g., a Bluetooth radio) to communicate when communication attempts from the first communication resource are denied. The denial rates are chosen to achieve threshold levels of performance for the first and second communication resources. The second denial rate may be set and the first denial rate adjusted in a looped manner to achieve desired Bluetooth performance. The denial rates may be set to deny all first communication attempts but to allow all second communication attempts. Final attempts to transmit Bluetooth packets may be given priority regardless of the first and second denial rates.

摘要： In user equipments (UEs) with multiple radios, interference between those radios may be reduced by monitoring radio performance and adjusting aggressor transmit power levels to ensure victim and aggressor performance stay within desired operational levels. Various factors may determine when a reduced power approach is desired. Such factors may include aggressor transmit power, received signal strength indicator, victim error rate, throughput loss, coverage impact, etc. Various methods of reducing transmit power may be used. For example, for Long Term Evolution communications, a power headroom report may be altered to adjust a modulation coding scheme and bandwidth allocated for a particular UE. For Bluetooth communications a power control mechanism may be overridden to ensure a device stays within a desired transmit power. A power reduction loop may be employed to monitor a device's transmit power.

摘要： Techniques are provided for performing hierarchical coding in a multi-antenna communication system (e.g., a SIMO, MISO, or MIMO system). At a transmitter, a base stream and an enhancement stream are coded and modulated separately to obtain first and second data symbol streams, respectively. The first data symbol stream is processed in accordance with a first spatial processing scheme (e.g., a transmit diversity or a spatial multiplexing scheme) to obtain a first set of symbol substreams. The second data symbol stream is processed in accordance with a second spatial processing scheme (e.g., transmit diversity or spatial multiplexing) to obtain a second set of symbol substreams. The first set of symbol substreams is combined (e.g., using time division multiplexing or superposition) with the second set of symbol substreams to obtain multiple transmit symbol streams for transmission from multiple transmit antennas. A receiver performs complementary processing to recover the base stream and enhancement stream.

摘要： To mitigate potential interference between radio access technologies (RATs) on a multi-RAT device, traffic scheduling rules may be implemented so that communications of the individual RATs are timed in a manner that reduces interference. For example, communications of a Bluetooth/WLAN RAT may be scheduled such that initial and responsive communications of the Bluetooth/WLAN RAT occur during sub-frames of an LTE RAT that are less likely to cause cross-RAT interference.
