    Abstract: Methods, systems, and devices for wireless communications are described that provide for configuration of channel bandwidth that may be specific to a particular user equipment (UE). A UE may be configured with a channel bandwidth that is less than or equal to a channel bandwidth of the serving base station, and may also be different than a channel bandwidth of one or more other UEs that are served by the base station. The base station may signal the UE-specific channel bandwidth in UE-specific signaling, such as UE-specific radio resource control (RRC) signaling.

  • Patent number: 11057871
    Abstract: Methods, systems, and devices are described for wireless communications. A wireless device may receive an allocation of uplink resources for an uplink transmission of uplink control information (UCI) during a long physical uplink control channel (PUCCH), which may range from four to fourteen symbol periods in length. The wireless device may identify a frequency hopping location based on the length of the PUCCH and a number of bits used to represent the UCI. In some cases, the frequency hopping location partitions the long PUCCH into a first set of symbol periods and a second set of symbol periods. After identifying the frequency hopping location, the wireless device may transmit a UCI message, which may include information and reference symbols, over a first frequency bandwidth during the first set of symbol periods and over a second frequency bandwidth during the second set of symbol periods.

  • Patent number: 11057837
    Abstract: A device, such as a base station or user equipment (UE), may identify a narrowband reference signal (NB-RS) energy per resource element (EPRE) for a NB-RS to be transmitted in a wireless transmission. The device may identify a ratio of a narrowband physical downlink shared channel (N-PDSCH) EPRE to the NB-RS EPRE for orthogonal frequency division multiplexing (OFDM) symbols containing neither a cell-specific reference signal (CRS) nor a NB-RS. In deployments where NB transmissions are transmitted in a guard-band adjacent to a wideband system bandwidth, a device may identify a second ratio for N-PDSCH EPRE to CRS EPRE within OFDM symbols containing CRS. In deployments where NB transmissions are transmitted in-band with the wideband system bandwidth, a device may identify a third ratio of NB-RS EPRE to CRS EPRE, and a fourth ratio of N-PDSCH EPRE to NB-RS EPRE within OFDM symbols containing NB-RS transmissions.

  • Patent number: 11051324
    Abstract: Aspects of the present disclosure provide mechanisms for utilizing a single uplink grant to transmit scheduling requests (SRs) for two or more logical channels. A base station may allocate a separate grant of uplink resources for each SR opportunity (e.g., each logical channel for which a user equipment (UE) may transmit a SR to the base station). When the allocated uplink resources are within the same time period, the UE may select a subset of the SR opportunities for which to transmit a SR and partition the subset into one or more groups of SR opportunities. The UE may then generate one or more SR bits representing the one or more groups of SR opportunities and transmit the one or more SR bits on the single uplink grant.

  • Publication number: 20210144039
    Abstract: Methods, systems, and devices for wireless communications are described. Pre-discrete Fourier transform (DFT) time-domain spreading codes may be applied for UE multiplexing for uplink control information (e.g., over shared resources of an uplink slot). For example, a moderate number of UEs may be multiplexed within the same slot by having each UE spread modulation symbols before DFT-spreading by different spreading code. For orthogonality across UEs, the pre-DFT spreading codes may be selected as orthogonal cover codes (OCCs). The spreading sequences can be generated from a set of any orthogonal sequences or generated from unitary matrices. In some cases, orthogonality in the time domain may be kept as well as a frequency division multiplexed (FDM) structure in the frequency domain. For such property, a Fourier basis OCC design may be used. In some other examples, a Hadamard matrix based OCC design may be used.
