  • Transmission and reception of broadcast information in a wireless communication system
    Patent number: 10652856
    Abstract: Systems and methods for transmitting and receiving other broadcast information, OBI, are disclosed. In some embodiments, a method of operation of wireless communication device for a wireless communication system comprises receiving and decoding a transmission unit in which OBI is collocated with at least a portion of a Synchronization Signal Block (SSB). The SSB comprises a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH). The OBI comprises paging messages, remaining minimum system information (RMSI), and/or random access response (RAR) messages. In some embodiments, the transmission unit is a transmission unit having a duration that is two or more symbols but less than a duration of a full slot. In this manner, resources of the wireless communication system are efficiently utilized, which results in higher link and system capacity as well as lower network power consumption from increased stand-by times.

  • Method and Apparatus for Providing Channel State Information Status by a Transceiver
    Publication number: 20200127720
    Abstract: In one aspect of this disclosure, a transceiver obtains and transmits a CSI status indicator. In one example, the CSI status indicator indicates that previously reported CSI is outdated and/or that a new CSI report is available at the transceiver. In some embodiments, the transceiver generates or transmits the CSI status indicator according to a particular configuration, which may be set by a supporting wireless communication network. The configuration may include criteria on when to transmit the CSI status indicator, such as configuration criteria indicating that the transceiver should transmit the CSI status indicator responsive to completing its determination of a full-dimension beamforming matrix to be used for controlling beamforming towards the transceiver. The transceiver comprises, for example, a wireless device operating within a wireless communication network and the CSI status indicator corresponds to the status of downlink CSI.

  • Using an uplink grant as trigger of first or second type of CQI report
    Patent number: 10595337
    Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.
