摘要:
A method, an apparatus, and a computer program product for wireless communication are provided in which a resource assignment utilizing the PDCCH and/or the R-PDCCH may be addressed to a group of UEs, rather than an individual UE, by utilizing a group identifier for indicating to the group that there may be information for any UE in the group in the PDSCH. In this way, the capacity of the PDCCH, which is limited, is multiplied and a potential bottleneck at PDCCH scheduling can be relieved.

A low complexity List Viterbi algorithm (LVA) for decoding tail biting convolutional codes (TBCCs) has lower complexity than a solution of running the LVA algorithm for all states. In one aspect, a low complexity LVA-TBCC process includes finding a list of states from a single Viterbi algorithm and finding a list of potential codewords for each state in the state list using the LVA. A cyclic redundancy check may prune out false solutions. The disclosed method may be applied to many communication systems to improve error performance similar to LTE downlink PBCH decoding enhancements.

A method, an apparatus, and a computer program product for wireless communication arc provided. The apparatus may be a UE. The UE may enter a gated mode including a first time period followed by a second time period, prevent application initiated data generated during the first time period from being transmitted over-the-air during the first time period, and permit over-the-air transmission during the second time period of the application initiated data generated during the first time period.

Certain aspects of the present disclosure propose methods for protecting channel quality indicator (CQI) modulation symbols in a subframe (e.g., a localized frequency division multiplexing (LFDM) subframe). For some aspects, a timing adjustment method may be utilized to adjust time of a UE with respect to an eNodeB. The timing adjustment method may introduce a positive time offset to be used for reducing time mismatch between the UE and the eNodeB. In another aspect, a buffer may be used at the eNodeB to store symbols received by the eNodeB before removing the cyclic prefix information from the subframe. The eNodeB may use the stored symbols and an artificial time delay to ensure that the CQI information is protected. For some aspects, the CQI modulation symbols may not be located at the beginning of an LFDM symbol.

摘要:
In wireless communications, adaptive gain control may be performed by scaling of signals before and after a transform. A received signal power may be non-causally scaled to a first level within a desired range before transforming the received signal. The scaled signal is transformed between a time domain to a frequency domain and then its power is again non-causally scaled based on the first level. A feed forward circuit may be used in the power scaling. Different portions of the signal may be power adjusted independently of other portions. The different portions may be separated on a per-channel basis. Power scaling may be done on a symbol-by-symbol basis.

A method of wireless communication includes determining a number of symbols for uplink control information (UCI) on each of a plurality of layers, multiplexing symbols for the UCI with data on multiple layers such that the symbols are time aligned across the layers, and sending the multiplexed symbols on the multiple layers on uplink. In some designs, the number of symbols for the UCI may be determined based on a spectral resource parameter.

A method of wireless communication comprises receiving a plurality of codewords and transmitting a downlink feedback message by spatially bundling acknowledgments for the received plurality of codewords. In some designs, an accompanying grant message is transmitted with the downlink feedback message.
