摘要： A first network node (110; 111; 112; 130), a wireless device (120) and methods thereof, for managing one or more uplink resources between the wireless device (120) and a wireless communication network (100) are provided. The first network node (110; 11; 112; 130) compiles (204; 401) resource information about uplink resources available for the wireless device (120) to select and request for uplink scheduling. Said resource information associates each one of multiple such uplink resources with one or more downlink reference signals. The first network node (110; 111; 112; 130) sends (205; 402) the compiled resource information to the wireless device (120). The wireless device (120 ) 10 is thereby enabled to select, based on the resource information, e.g. ASRT information and said one or more downlink reference signals, at least one of said uplink resources to request for uplink scheduling.

摘要： Methods and nodes relating to paging of one or more wireless communication devices (120a-b) of a certain category. A radio network node (110a) is comprised in a wireless communication network (100) and obtains (201; 301; 501) an indication that a wireless communication device (120a) is of said certain category. The radio network node (110a) and the wireless communication device (120a) derive (202; 302; 402; 502; 701), based on that the wireless communication device (120a) is of said certain category according to the obtained indication, a Radio Network Temporary Identifier (RNTI) for the wireless communication device (120a). The RNTI being based on that the wireless communication device (120a) is of said certain category. The radio network node (110a) sends (203; 303; 503) and the wireless communication device (120a) receives downlink control information with a cyclic redundancy check value scrambled with the derived RNTI.

摘要： A wireless device 130 and a method for performing Channel-State Information (CSI) measurements. The wireless device 130 and a Radio Network Node (RNN) 110 serving the wireless device 130 are operating in a wireless communications system 100. The wireless device 130 receives, from the RNN 110, information relating to a first resource for CSI measurement and an indication to determine a second resource for CSI measurement, which indication relates to the first resource for CSI measurement. Further, the wireless device 130 determines the second resource for CSI measurement based on the information relating to the first resource and on information comprised in the indication, which second resource for CSI measurement is different from the first resource for CSI measurement. Furthermore, the wireless device 130 performs an CSI measurement on the second resource.

摘要： One aspect of the teachings herein involves the temporary transfer of radio identities from one service area of a wireless communication network to another service area, where the individual radio identities are used to differentiate individual radio connections between the network and respective wireless nodes supported by the network. In particular, the temporary transfer of a given radio identity from its default service area for use in another service is limited temporally and/or geographically. Limiting the temporal and/or geographic scope of the radio identity transfer allows the network to substantially maintain default associations of radio identities and their respective service areas, which allows the network to prevent or reduce the use of conflicting radio identities in the same service area. Transfer signaling may be used transfer radio identities, and such signaling may include the temporal and/or geographic restrictions, to control the migration spread of borrowed identities in the network.

摘要： Some embodiments herein relate to method in a user equipment for determining a transmit power to be used by the user equipment when transmitting in a radio communications network, which user equipment is served by a radio network node in the radio communications network. The user equipment receives, from the radio network node, an indication indicating a set of power control parameters out of multiple sets of power control parameters, which multiple sets of power control parameters are stored at the user equipment. The user equipment determines a transmit power based on the indicated set of power control parameters.

摘要： An access node (110) of a cellular network sends a first access information table in a broadcast transmission to a plurality of communication devices (10). The first access information table comprises a first group of entries. Each entry of the first group indicates one or more parameters for controlling access of the communication devices (10) to the cellular network and is mapped to an identifier from a first group of identifiers. Further, the access node (110) sends a second access information table in a unicast transmission to one of the communication devices (10). The second access information table comprises a second group of entries. Each entry of the second group indicates one or more parameters for controlling access of the communication device (10) to the cellular network and is mapped to an identifier from a second group of identifiers.

摘要： A receiver apparatus receives a terminal-specific demodulation reference signal having a rank k and estimates an effective multi-layer channel response, using the received terminal-specific demodulation reference signal. The receiver demodulates first data symbols from first time-frequency resource elements, using the estimate of the effective multi-layer channel response and using a first symbols-to-virtual-antenna mapping matrix M to obtain nc modulation symbols from each of the first time-frequency resource elements, wherein nc>1 and wherein the first symbol-to-transmit-layer mapping matrix M has dimensions k by nc. The first data symbols are decoded to obtain downlink control information assigning second time-frequency resource elements to the receiver. The receiver demodulates second data symbols from the second time-frequency resource elements, using the estimate of the effective multi-layer channel response, to obtain nd modulation symbols from each of the second time-frequency resource elements, wherein 1
