摘要： Systems and methodologies are described that facilitate signaling and detecting discontinuous transmission (DTX) in a wireless communication environment. A DTX indicator and Channel Quality Indicator (CQI) feedback can be multiplexed within a common uplink control channel subframe and transmitted to a base station when the access terminal is operating in DTX mode for an Acknowledgement Channel. Further, when operating in non-DTX mode, the access terminal can multiplex an ACK indicator or a NAK indicator with the CQI feedback within a common uplink control channel subframe, which can thereafter be transferred to the base station. Accordingly, the base station can detect DTX operation or non-DTX operation of the access terminal. For example, reference signal symbols can carry one of the DTX indicator, the ACK indicator, or the NAK indicator. Pursuant to another example, the CQI feedback and the DTX indicator can be combined and carried jointly by non-reference signal symbols.

摘要： A communication system incorporates a multiplexing scheme so that a base node that schedules user equipment (UE) can determine whether an ACK/NACK and/or a service request (SR) has been received when both uplink (UL) transmissions are simultaneously scheduled. Significant complexity reduction, better link efficiency, and higher multiplexing capability since the base node can interpret selective use by the UE of either the ACK/NACK or SR UL channel. Such interpretation can be extended to when multiple downlink (DL) transmission modes can be used, specifically DL single input multiple output (SIMO), DL multiple input multiple output (MIMO) with rank 1 transmission, and DL MIMO with rank 2 transmission. Based upon knowledge of the scheduling and DL transmission mode, the base node does not have to blind decode a number of possibilities due to the mapping of possible responses from the UE. In addition, the multiplexing scheme is applicable to FDD and TDD.

摘要： Systems and methodologies are described that facilitate interleaving encoded control channel information for transmission over an uplink channel. The encoded control channel information, for example, can include encoded Channel Quality Indicator (CQI) information, encoded Precoding Matrix Indicator (PMI) information, and/or Rank Indicator (RI) information. CQI information, PMI information, and/or RI information can be encoded at an access terminal, for instance, by applying a punctured Reed Muller block code to generate a sequence of encoded bits. The encoded bits can be interleaved to reorder the sequence utilizing one or more interleaving approaches. Examples of interleaving approaches that can be leveraged include prime number based interleaving, generalized bit reversal interleaving, column-row interleaving with column bit reversal, and/or M-sequence based interleaving. Further, the reordered sequence of encoded bits can be transmitted to a base station over an uplink channel.

摘要： Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.
