Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

Abstract: Techniques are described for wireless communication. One method of wireless communication includes buffering a first set of coded bits including a first control message having a plurality of fields, buffering a second set of coded bits including a second control message having the plurality of fields, soft combining at least a first subset of the first set of coded bits and a second subset of the second set of coded bits in a combined set of coded bits, and decoding the first control message or the second control message based at least in part on the combined set of coded bits.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may identify a codebook matrix having a number of rows equal to a first number and a number of columns equal to a second number, the first number equal to a number of UEs supported for communication with a base station, and the second number equal to a sequence length of a set of UE specific signature sequences, where the rows of the codebook matrix comprise a Welch bound equality (WBE) achieving vector set. The UE may identify a UE specific signature sequence based at least in part on a mapping between an identifier associated with the UE to one or more rows of the codebook matrix, and communicate with the base station based at least in part on the UE specific signature sequence.

Abstract: Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an offset value from a first modulation and coding scheme relating to a first code rate for a payload data transmission. The UE may determine, for a transmission of uplink control information, a second modulation and coding scheme, relating to a second code rate, that is different from the first modulation and coding scheme based at least in part on the offset value. The UE may transmit the uplink control information using the second modulation and coding scheme based at least in part on determining the second modulation and coding scheme. In some aspects, a UE may segment uplink control information. Numerous other aspects are provided.

Abstract: Various aspects described herein relate to communicating hybrid automatic repeat/request (HARQ) feedback. HARQ feedback related to a HARQ communication over one or more links can be received from a user equipment (UE), wherein the HARQ feedback includes at least one or more interference parameters and/or one or more predicted interference parameters. A rate control loop for each of one or more interference patterns corresponding to each of the one or more links can be maintained based at least in part on the one or more interference parameters. A scheduling grant can be generated for the UE for another instance of the HARQ communication based at least in part on the rate control loop and the one or more predicted interference parameters.

Abstract: Aspects of the disclosure relate to a configurable subframe structure for use in next generation (e.g., fifth generation or 5G) wireless networks utilizing a time division duplex (TDD) carrier that minimizes interference with adjacent legacy wireless networks. The configurable subframe structure may be configured to produce next generation subframes, each including at least one of a downlink portion or an uplink portion, to substantially align downlink portions with corresponding legacy downlink subframes and/or uplink portions with corresponding legacy uplink subframes.
