    摘要: Exemplary embodiments include methods for activating or deactivating reference signal (RS) resources usable for management of transmit and/or receive beams for communication with a user equipment (UE) in a wireless communication network. Embodiments include sending, to the UE, one or more control messages comprising configuration of a plurality of RS resources associated with a particular bandwidth part (BWP) of a particular component carrier (CC) in the network. Embodiments also include sending, to the UE, a further control message comprising identification of at least one RS resource, of the plurality, to be activated or deactivated. The further control message can also include, for each identified RS resource, an indication of the identified RS resource's spatial relation with a further resource that is not associated with the particular BWP of the particular CC. Embodiments also include complementary methods performed by a UE, and apparatus configured to perform the exemplary methods.

    摘要: Exemplary embodiments include methods performed by a network node to configure PUCCH resources usable in communication with UE in a wireless network. Embodiments include sending, to the UE, one or more control messages comprising: configuration of a plurality of PUCCH resources; and identification of a plurality of spatial relations associated with one or more reference signals transmitted by the UE or the network node. Embodiments also include sending, to the UE, a further control message comprising: identification of a first spatial relation of the plurality of spatial relations; and indication of whether the first spatial relation applies to a single PUCCH resource of the configured PUCCH resources, or to at least one group of PUCCH resources of the configured PUCCH resources. Exemplary embodiments also include complementary methods performed by a UE, as well as network nodes and UEs configured to perform the exemplary methods.

    摘要: An access node transmits, in a downlink signal having a series of subframes, a beam-formed reference signal in subframes, where the beam-formed reference signals are transmitted in fewer than all of the subframes of the downlink signal. A first subset includes beam-formed reference signals corresponding to a first frequency or first localized range of frequencies, and a second subset includes beam-formed reference signals corresponding to a second frequency or second localized range of frequencies. The second frequency or second localized range of frequencies is spaced apart from and differing from the first frequency or first localized range of frequencies. A user equipment, UE, receives, in the downlink signal, the beam-formed reference signal in each of a plurality of subframes. The UE performs mobility management measurements using at least the first subset of the received beam-formed reference signals and performs RLM using the second subset of the received beam-formed reference signals.

    摘要: A method (20) of neighbor cell detection performed in a communication device (35) is disclosed. The method (20) comprises selecting (21) at least one subband-time interval resource for processing, wherein each subband is part of a system frequency bandwidth and each time interval is a part of a synchronization signal repetition time period, recording (22) one or more radio samples associated with the at least one subband-time interval resource, executing (23) cell detection on the recorded radio samples, and repeating (24) the selecting (21), recording (22) and executing (23) until a stop criterion is fulfilled. A corresponding communication device (35) computer program (32) and computer program product (31) are also provided.

    摘要: A handover control method for network nodes of a cellular communication network is disclosed.
    According to the method, a network node performs uplink signal strength measurements in relation to a wireless communication device operating in association with the cellular communication network, compensates the uplink signal strength measurements based on an available downlink transmission power value of the network node, and transmits the compensated uplink signal strength measurements to another network node.
    The other network node then bases a handover decision on an estimated downlink received power of the wireless communication device in relation to the other network node, wherein the estimated downlink received power is based on the compensated uplink signal strength measurements.
    Corresponding computer program products, arrangements and network nodes are also disclosed.

    摘要: This disclosure provides by a method for transmitting a mobility reference signal, MRS, during a mobility measurement session to a wireless device, WD. The method is performed in a radio access network node, RANN. The RANN is configurable to transmit using a set of transmission beams. The method comprises dynamically assigning, a MRS identifier to each candidate transmission beam in a set of candidate transmission beams. The method comprises transmitting control information to the WD, the control information comprising the MRS identifier for each corresponding candidate transmission beam; and transmitting the mobility reference signal, MRS, to the WD in accordance with the transmitted control information.
