  • Publication number: 20230093335
    Abstract: Systems and methods for low complexity multi-configuration Channel State Information (CSI) reporting are provided. In some embodiments, a method of operating a wireless device in a cellular communications network to provide CSI feedback from multiple CSI reporting configurations is provided. The method includes receiving a first and second CSI reporting configuration and then reporting updated CSI in a CSI report for only one of the first CSI reporting configuration and the second CSI reporting configuration. In this way, rich CSI feedback with many ports, different codebooks, mixed beamformed and non-precoded CSI-RS configurations, etc., can be supported while requiring less computational complexity in the wireless device.

  • Publication number: 20230085837
    Abstract: A network node signals to a wireless communication device which precoders in a codebook are restricted from being used. The network node in this regard generates codebook subset restriction signaling that, for each of one or more groups of precoders, jointly restricts the precoders in the group by restricting a certain component (e.g., a certain beam precoder) that the precoders in the group have in common. This signaling may be for instance rank-agnostic signaling that jointly restricts the precoders in a group without regard to the precoders transmission rank. Regardless, the network node sends the generated signaling to the wireless communication device.

  • Patent number: 11552681
    Abstract: A method for assisting the adaptation of a signal from a first node to a second node is provided. The first node communicates with the second node in a wireless communication system over a radio link. The second node has a codebook comprising a set of possible information alternatives for assisting the adaptation of a signal received from the first node. The second node may select an information alternative from the codebook and send it to the first node to assist the first node in adapting the signal. The first node is configured with a number of subsets, each comprising a part of the possible information alternatives. The first node requests that the second node restrict the selection of information alternatives to one of the subsets, and in response, receives an information alternative from the second node that is selected from among the subsets configured according to the configuration request.

    Abstract: Methods and arrangements are described for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple-Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported, and the modes have partly shared signaling. SU-MIMO mode signaling which is not needed for MU-MIMO mode signaling is identified. Data bits of the identified signaling is interpreted to comprise signaling information associated with MU-MIMO mode.

  • Patent number: 11362713
    Abstract: Methods, apparatus and computer programs are disclosed for controlling the output of a transmission point for a wireless communications network. One embodiment provides a method for controlling the output of a transmission point for a wireless communications network. The method comprises determining an average output power of the transmission point over a period of time; comparing the average output power to an output power reference value; and allocating data, to be transmitted by the transmission point to one or more wireless devices, to a pool of radio resources. The pool of radio resources is adjusted as a function of the comparison between the average output power and the output power reference value, and the output power reference value varies as a function of a maximum antenna gain of an antenna array of the transmission point during the period of time.

  • Publication number: 20220131659
    Abstract: Coordinated multi-point transmission of user data from a first cell serving a wireless terminal and a neighboring second cell site is performed. The first cell site maps control signals and user data to time-frequency resources according to a first mapping pattern. The second cell site maps control data and traffic data to time-frequency resources according to a second mapping pattern. A wireless terminal extracts user data according to the first mapping pattern and detects a control element transmitted by the first cell site. The control element indicates that user data associated with the control element is mapped to the time-frequency resources according to the second mapping pattern. In response, the wireless device extracts user data according to the second mapping pattern from time-frequency resources of a second transmission for the wireless terminal transmitted from the second cell site.

  • Patent number: 11245449
    Abstract: Method performed by a network node (210) to indicate a first and a second set of antenna ports. The network node (210) indicates (803) to a wireless device (250) at least one of: a) a first indication of a first set (M?) of antenna ports for first measurements on first radio signals, the first measurements associated with periodic reporting, and b) a second indication of a second set (M) of antenna ports for second measurements on second radio signals, the second measurements associated with aperiodic reporting. The first set is different than the second set. The periodic and the aperiodic reporting are by the wireless device (250) and correspond to a same Channel State Information, CSI, process. The network node (210) also transmits (804), to the wireless device (250), the first radio signals, periodically, over the first set and the second radio signals over the second set.

  • Patent number: RE49329
    Abstract: The teachings herein present a method and apparatus that implement and use a factorized precoder structure that is advantageous in terms of performance and efficiency. In particular, the teachings presented herein disclose an underlying precoder structure that allows for certain codebook reuse across different transmission scenarios, including for transmission from a single Uniform Linear Array (ULA) of transmit antennas and transmission from cross-polarized subgroups of such antennas. According to this structure, an overall precoder is constructed from a conversion precoder and a tuning precoder. The conversion precoder includes antenna-subgroup precoders of size NT/2, where NT represents the number of overall antenna ports considered. Correspondingly, the tuning precoder controls the offset of beam phases between the antenna-subgroup precoders, allowing the conversion precoder to be used with cross-polarized arrays of NT/2 antenna elements and with co-polarized arrays of NT antenna elements.
