摘要： Methods, systems, and devices for wireless communication are described. In multi-user (MU) multiple-input multiple-output (MIMO) wireless communications systems, a base station may perform signaling to indicate information related to ports assigned to one or more UEs. The base station may also signal information regarding ports shared with other UEs, which the UE may use when performing channel estimation. In some examples, the base station may signal a number of ports used per sub-band to the UE or a number of demodulation reference signal (DMRS) ports used by the UE. The base station may signal a sub-set of a total number of ports that are shared by other UEs overlapping with the resource allocation of the UE. The signaling may indicate a number of combs used by the base station in the resource allocation for the UE.

摘要： Downlink schemes are disclosed for a cooperative user equipment (UE) with joint baseband processing. UEs may establish a cooperative UE unit with one or more neighboring UEs, where one of the UEs operates as the primary UE. The participating UEs of the cooperative UE unit determine a downlink transmission scheme for the cooperative transmissions from a serving base station and receive cooperative transmissions of one or more transport blocks from the serving base station according to the downlink transmission scheme. The secondary UEs of the cooperative UE unit generate and transmit cooperative process data to the primary UE, where the cooperative process data is based on the receipt of the cooperative transmissions by the secondary UEs. The primary UE processes its received cooperative transmission along with the cooperative process data to decode the one or more transport blocks. Other aspects and features are also claimed and described.

摘要： Aspects of the disclosure relate to methods and apparatus of time-domain multiplexing (TDM) for reference signals (RS) and data using a modified cyclic prefix. A reference signal (RS) and data are multiplexed either in a single symbol or in two time consecutive symbols that respectively including the RS and data. The cyclic prefix (CP) is added to the single symbol using a portion of the RS or to a first symbol of the two time consecutive symbols using a portion of the RS. The CP may be copied from the RS or the end of the symbol, but not the data, in a manner that affords a virtual Time Division Multiplexing (TDM) of the RS and data before discrete Fourier transform (DFT) spreading is performed in a transceiver to provide lower peak to average power ratios and no Inter-symbol interference.

摘要： Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may monitor a search space of a control channel for at least one downlink transmission. The UE may perform a plurality of decoding operations on a plurality of decoding candidates associated with the downlink control information format transmitted in a plurality of transmission time intervals (TTIs). In some cases, the plurality of decoding operations may comprise performing a first decoding on a first decoding candidate received in a current TTI, the first decoding operation applying a first descrambling code to the first decoding candidate, and performing a second decoding operation on a combined decoding candidate that comprises soft combined information from the first and second decoding candidate, the second decoding candidate received in a prior TTI.

摘要： Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.
