摘要： Techniques to more efficiently transmit pilot and signaling on the uplink in an OFDM system. With subband multiplexing, M usable subbands in the system are partitioned into Q disjoint groups of subbands. Each subband group may be assigned to a different terminal for uplink pilot transmission. Multiple terminals may transmit simultaneously on their assigned subbands. The transmit power for the pilot may be scaled higher to attain the same total pilot energy even though S instead of M subbands are used for pilot transmission by each terminal. Pilot transmissions from the terminals are received, and a channel estimate is derived for each terminal based on the pilot received on the assigned subbands. The channel estimate comprises a response for additional subbands not included in the assigned group. Subband multiplexing may also be used for uplink signaling transmission.

摘要： A rate adaptive transmission scheme for MIMO systems, which can transmit a variable number of data symbol streams, provide transmit diversity for each data symbol stream, and fully utilize the total transmit power of the system and the full power of each antenna. In one method, at least one data symbol stream is received for transmission from a plurality of antennas. Each data symbol stream is scaled with a respective weight corresponding to the amount of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennas. The transmit basis matrix (e.g., a Walsh-Hadamard matrix or a DFT matrix) is defined such that each data symbol stream is transmitted from all antennas and each transmit symbol stream is transmitted at (or near) the full power for the associated antenna.

摘要： Techniques to determine a set of rates for a set of data streams to be transmitted in a multi-channel communication system. A group of transmission channels to be used for each data stream is initially identified. An equivalent system for each group is then defined to have an AWGN (or flat) channel and a spectral efficiency equal to the average spectral efficiency of the transmission channels in the group. A metric for each group is then derived based on the associated equivalent system, e.g., set to the SNR needed by the equivalent system to support the average spectral efficiency. A rate for each data stream is then determined based on the metric associated with the data stream. The rate is deemed to be supported by the communication system if the SNR required to support the data rate by the communication system is less than or equal to the metric.

摘要： Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

摘要： Physical random access channel (PRACH) configuration on new radio unlicensed (NR-U) networks is disclosed. A UE may perform PRACH transmission either with a transmission opportunity (TXOP) or outside of a TXOP. The UE monitors for a control signal from a base station, such as a preamble or common control signal, identifying a TXOP. The UE may obtain an autonomous random access configuration for communications outside of the current TXOP that identifies a random access slot includes a plurality of random access occasions. If the UE fails to detect the control signal, it transmits an autonomous random access signal in a random access occasion corresponding to a beam direction of its location in relation to the base station. Otherwise, upon detection of the control signal and receipt of a trigger signal, the UE may transmit a random access request within the TXOP.

摘要： Synchronization signal block (SSB) multiplexing and remaining material system information (RMSI) monitoring in new radio unlicensed (NR-U) networks are disclosed. For SSB multiplexing, a user equipment (UE) receives an SSB configuration for a discovery signal detection window having a plurality of communication slots, wherein, based on the SSB configuration, UE identifies random access resource and time and frequency locations to monitor remaining minimum system information (RMSI) configured for each SSB. The UE further receives an SSB transmission indicator that reflects a listen before talk (LBT) result, which it may use with the SSB configuration to map one or more SSB for rate matching in selected slots. The UE can then rate match any data transmissions around the identified SSBs in those identified slots regardless of LBT result. The UE may further leverage the SSB configuration and indication of LBT result to monitor SSB transmissions for control resource set (CORESET) transmissions.

摘要： The extension of NB-IoT and eMTC communications into the unlicensed spectrum introduces a number of problems associated with channel quality measurement and reporting. A method, apparatus, and computer readable medium are presented that provide a technique for channel quality measurement and reporting that addressed such problems. A UE apparatus measures a CQI measurement for each of a plurality of groups of hopping frequencies, wherein a set of hopping frequencies is grouped into the plurality of groups and reports a CQI for each of the plurality of groups. A base station may configure the UE for CQI reporting and may receive a CQI for each of a plurality of groups of hopping frequencies, wherein a set of hopping frequencies is grouped into the plurality of groups. The set of hopping frequencies comprise frequencies in an unlicensed spectrum.
