摘要： Aspects of the present disclosure provide methods and apparatus for improving UL-based mobility. As described herein, a UE may determine it has failed to decode a first keep alive (KA) signal during a wake period of a discontinuous receive (DRx) cycle and may extend the wake period to monitor for a second KA signal, in response to the determination. An access network controller may select, while a (UE) is currently served by a first transmit/receive point (TRP), a second TRP to serve the UE, configure the first TRP to transmit a first keep alive (KA) signal, in response to a chirp signal received from the UE, and configure the second TRP to transmit a second KA signal after the first KA signal transmitted by the first TRP.

摘要： Various aspects of the disclosure relate to a codebook design that defines phase rotation on one or more layers of a codebook. This codebook may be used, for example, for sparse code multiple access (SCMA) encoding. One feature pertains to a method of communication that includes receiving at least one input signal, and mapping each of the at least one input signal to a corresponding layer of a codebook, where the codebook defines phase rotation between the layers. The method may further include generating a coded signal for each of the at least one input signal on each corresponding layer based on the codebook, and generating an output signal based on each generated coded signal.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a lower code rate by splitting a data stream into multiple data sub-streams. The UE may split the data stream to synchronously encode, modulate, and spread the data sub-streams at different layers. Then, the UE may superpose or combine the sub-streams together. The UE may scramble the combined data stream with a UE-specific scrambling code. In some examples, the UE may then apply a cyclic prefix to the combined data stream. The UE may then transmit the combined data stream to a base station. The receiving base station may use layer-wise matched filters and element-wise signal estimators (ESE) to obtain soft information such as log-likelihood ratios. Channel decoders may then determine estimated bits for each layer of each user of the combined data stream.

摘要： Methods, systems, and devices for wireless communication are described. A device—such as a base station or user equipment (UE)—may transmit a demodulation reference signal (DMRS) including signaling information in addition to channel estimation information. To improve reception of the DMRS signaling information, the transmitting device may employ data protection techniques to the signaling information and modify a data payload transmitted in the physical data channel associated with the DMRS. In one aspect, the transmitting device may modify cyclic redundancy check (CRC) bits in the payload to include verification for the signaling information. In another aspect, the transmitting device may determine a scrambling code based on the signaling information, and may scramble the payload based on the scrambling code.

摘要： Systems and methods herein create unified synchronization to support various network deployments in which multiple UE states (e.g., idle, connected, etc.) and multiple synchronization signal periodicities (5 ms, 20 ms, etc.) and standalone/non-standalone networks may exist. Unified synchronization may be achieved at least by designating transmit frames as being even or odd. With such a designation, when a network transmits synchronization signals (SS) comprising the most significant bits (MSB)s of a frame's system frame number (SFN), a UE of any state may receive the SS according to any periodicity and blind decode the SFN's least significant bits (LSBs) with less complexity as compared to traditional systems and methods due at least to the even or odd frame designations.

摘要： Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.
