    摘要: A wireless communication system is presented for adaptive uplink (UL) link adaptation (LA). The adaptive UL LA can include multiple outer loops, for which multiple block error rate (BLER) filtering is performed. Each of the multiple BLER filtering can be performed on groups or sub-groups of subframes, in which each group has the same or similar coding characteristics. For example, one group in TD-LTE could be subframes with sounding reference signal (SRS) and another group could be subframes without SRS. Each of the multiple BLER filtering can use the same or different BLER algorithm, BLER target and/or BLER parameters.

    摘要: Apparatus and methods for channel estimation in a Multimedia Broadcast Multicast Service (MBMS) Single Frequency Network (MBSFN) are disclosed. A representative method includes a wireless communication device receiving multiple frames, each frame including multiple subframes, each subframe including multiple symbols. The wireless communication device determines whether subframes include MBMS data or not. For subframes that include MBMS data, the wireless communication device excludes all or certain symbols of the subframes that include MBMS data from a channel estimation process. The wireless communication device determines whether the subframes include MBMS data based at least in part on a channel impulse response and/or a channel energy response for one or more symbols of the subframes.
