摘要： Methods, systems, and devices for wireless communication are described that support multiplexing uplink transmissions with transmit diversity with a single carrier waveform. Two or more UEs may be configured to use space time block codes (STBC) for transmissions using multiple uplink antennas. A first UE may be configured to use a first STBC for a first uplink transmission. An orthogonal cover code (OCC), such as a Walsh code, may be applied to the first STBC to generate a second STBC, and a second UE may use the second STBC for a second uplink transmission. The first UE and the second UE may concurrently transmit the first uplink transmission and the second uplink transmission. The first STBC and the second STBC may be applied across multiple OFDM symbols, or may be applied within an OFDM symbol on a modulated symbol level.

摘要： A method of providing spatial diversity for critical data delivery in a beamformed mmWave smallcell is proposed. The proposed spatial diversity scheme offers duplicate or incremental data/signal transmission and reception by using multiple different beams for the same source and destination. The proposed spatial diversity scheme can be combined with other diversity schemes in time, frequency, and code, etc. for the same purpose. In addition, the proposed spatial diversity scheme combines the physical-layer resources associated with the beams with other resources of the same or different protocol layers. By spatial signaling repetition to avoid Radio Link Failure (RLF) and Handover Failure (HOF), mobility robustness can be enhanced. Mission-critical and/or time-critical data delivery can also be achieved without relying on retransmission.

摘要： A method for operating a wireless device within a cellular network having at least two base nodes and providing common channels and at least one downlink non-common channel. The wireless device decodes at least one common channel and the downlink non-common channel, and performs the steps of determining a value relative to the total amount of resources provided by one of the base nodes, determining a value relative to the amount of resources provided by the one base node for the common channels out of the total resources, determining a value relative to the amount of resources suitable of being received by the wireless device, calculating the share of usable resources in comparison to said total resources excluding common resources, and adapting the operation of the wireless device within the cellular network in dependence of the calculated share of usable resources.
