Abstract: A first network node, a second network node and methods therein, for handling baseband processing of signals communicated with wireless devices in a wireless network. The first network node communicates a first type of signals with a first wireless device and performs a first part of baseband processing of the first type of signals using a non-GPP implemented processor. The first network node also communicates the first type of signals with the second network node for a second part of baseband processing of the first type of signals using a GPP implemented processor. The first network node further communicates a second type of signals with a second wireless device and performs both of said first and second parts of baseband processing of the second type of signals using the non-GPP implemented processor.

Abstract: According to certain embodiments, a method performed by a wireless device (110) for measurement reporting includes transmitting, to a network node (160), a first message to initiate a transition from a dormant state to a connected state. The wireless device receives, from the network node, a second message including an indication of whether the wireless device is to release or keep at least one measurement configuration for performing measurements while in the dormant state. Based on the first message, the wireless device determines whether to release or keep the at least one measurement configuration for performing measurements while the wireless device is in the dormant state.

Abstract: A method and decoder for determining that a decoder conforming to a first profile is capable of decoding a first picture of a video bitstream conforming to a second profile is provided. The method includes obtaining an indicator value, the indicator value indicating conformance to a profile. The method includes determining whether the first picture in the video bitstream is a still picture. The method includes responsive to the indicator value indicating conformance to the second profile and the first picture is determined to be a still picture, determining that the decoder conforming to the first profile is capable of decoding the first picture of the video bitstream.

Abstract: The present disclosure relates to a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24), and a radio base station (20) performing the method. In an aspect, a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24) is provided. The method comprises providing (S101) a first location with radio coverage using at least a first frequency band and a second frequency band and a second location with radio coverage using the first frequency band, the second frequency band being located at a higher frequency than the first frequency band and temporarily reallocating (S102) resources of the second frequency band from the first location to the second location upon acquiring an indication that a wireless communication device (24) at the second location requires improved coverage.

Abstract: A wireless device and a method therein for assisting in precoder selection for wireless communication with a Radio Node (RN), and a RN for performing precoder selection for wireless communication with a wireless device. The wireless device is configured with a set of precoders. The wireless device determines a subset of precoders out of the set of precoders; and transmits, to the RN, at least one Sounding Reference Signal (SRS) precoded with a respective at least one precoder comprised in the subset. The RN receives, from the wireless device, at least one SRS precoded with a respective at least one precoder comprised in a subset of precoders; and transmits, to the wireless device, a signal indicative of a selected precoder to be used for a transmission to the RN, wherein the selected precoder is indirectly selected based on the received at least one SRS.

Abstract: Core network equipment is configured for use in a core network of a wireless communication system. The core network equipment is configured to switch switching to using a new non-access stratum, NAS, security context between a user equipment and the core network equipment. The core network equipment is also configured to, during or in association with a handover procedure for handover of the user equipment, signal from the core network equipment that the new NAS security context between the user equipment and the core network equipment is to be used as a basis for an access stratum (AS) security context between the user equipment and radio access network equipment.

Abstract: The present disclosure provides methods for signaling QoS Flow control parameters, and corresponding NF entities. The method comprises generating one or more data flow rules associated with a QoS Flow and a QoS Flow profile. The data flow rules include parameters specific to a data flow that belongs to the QoS Flow, while the QoS Flow profile includes parameters that are common to all data flows that belong to the same QoS Flow. The present disclosure further discloses a corresponding method of receiving the QoS Flow control parameters. The present disclosure further provides corresponding computer readable medium.

Abstract: The present application relates to a method for verifying a Channel Quality Indicator (CQI) measurement performed by a first wireless device in a communication network. The communication network includes a Radio Access Network (RAN). The method includes: obtaining a first CQI measurement report including a first CQI measurement value of a measurement performed by the first wireless device on for a first downlink channel between a first RAN node and the first wireless device; identifying at least one neighbour wireless device to the first wireless device; obtaining at least one neighbour CQI measurement report from the at least one neighbour wireless device; aggregating the at least one neighbour CQI measurement report into a reference CQI measurement report set; and verifying the first CQI measurement value using the reference CQI measurement report set. The present application also relates to a verification node and a computer program product.
