  • Patent number: 10805038
    Abstract: A signaling channel that punctures traffic channels is used to send signaling, e.g., acknowledgments (ACKs). To send signaling, resources for the signaling channel are determined, e.g., based on a frequency hopping pattern. Signaling is spread with a spreading code (e.g., a Walsh code) to generate spread signaling, which is mapped to the resources for the signaling channel. Each resource may be partitioned into multiple clusters. A signaling message may be mapped to different clusters to achieve diversity. Traffic data may also be mapped to other resources for a traffic channel assigned for use. Traffic data mapped to the other resources for the signaling channel is punctured. The mapped signaling and traffic data are further processed (e.g., for OFDM or SC-FDMA) and transmitted.

  • Publication number: 20200322954
    Abstract: Various designs for optimization of carrier aggregation (CA) capability signaling are discussed. A user equipment (UE) configured for CA determines to signal supported CA combinations that include a band, the band being one of a first band and a second band. The first band is a superset of the second band. The UE signals the supported CA combinations that include the band to the network. A base station receives a signal indicating the CA combinations supported by the UE that include the band. The base station determines CA combinations that include the first band and CA combinations that include the second band based on the CA combinations received from the UE.

  • Publication number: 20200314780
    Abstract: A UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

  • Publication number: 20200252857
    Abstract: Device detection in networks with mixed mobility devices is discussed. Devices in the network first determine a discovery mode from a plurality of discovery modes, wherein the determining is based on a mobility state of the wireless device. The device identifies a set of resources associated with the determined discovery mode, wherein each of the plurality of discovery modes is provisioned with separate resources. A discovery signal is transmitted using the identified set of resources according to the discovery mode. Thus, devices with higher mobility will generally send discovery signals more often than devices that are static or semi-static.

  • Publication number: 20200204234
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for managing antenna modules, (such as radio frequency integrated circuits (RFICs)) to maximize power savings and minimize latency at a user equipment (UE). As described herein, a UE may identify an RFIC to use as an active RFIC for receiving a scheduled transmission based on an active transmission configuration indication (TCI) state or serving beam of a base station to be used for the scheduled transmission. The UE may then identify one or more remaining RFICs at the UE as either candidate RFICs for potentially replacing the active RFIC or as unused RFICs, and the UE may receive the scheduled transmission via the active RFIC or via a replacement active RFIC selected from the candidate RFICs.
