摘要： According to certain embodiments, a method performed by a wireless device comprises obtaining one or more parameters to determine coverage detection criteria. The coverage detection criteria indicates whether sidelink operation of the wireless device is considered to be inside or outside coverage of a cell. The method further comprises determining, based on the one or more parameters, whether the sidelink operation of the wireless device is considered to be inside or outside the coverage of the cell and adjusting the sidelink operation based on whether the sidelink operation of the wireless device is considered to be inside or outside the coverage of the cell.

摘要： A network node (840) and method therein for shaping an output power spectrum of a signal (920) to be transmitted in a wireless communications network are disclosed. The signal (920) is transmitted within a total frequency range or bandwidth comprising a first frequency bandwidth and a second frequency bandwidth. The network node increases or boosts a power of the signal (920) in a part of a first frequency bandwidth and/or decreases/deboosts a power of the signal (920) in a part of the total bandwidth outside the first frequency bandwidth. The network node then transmits the partly increased and/or decreased signal (920) to a wireless communication device (850) operating in the wireless communications network.

摘要： Suitable hopping patterns designed to alleviate degradations of SRSs are provided herein. When a UE (12, 14, 200) transmits multiple SRS within the same time resource (e.g., slot), the UE is configured with an SRS hopping pattern (including an SRS bandwidth) based on at least a UE configuration bandwidth. In one exemplary embodiment, a node (12, 14, 200), e.g., a UE (14, 200) or a network node (12, 200) of a wireless network (10), controls the SRS configurations for SRS transmissions by the UE (14, 200) via one or more resource blocks. The SRS configuration comprises a hopping pattern and a first (e.g., hopping) bandwidth associated with the SRS transmissions. The node (12, 14, 200) determines the first bandwidth, and determines a second (e.g., configuration) bandwidth associated with a configuration of the UE (14, 200). The node (12, 14, 200) determines the SRS configuration for the UE (14, 200) responsive to the first and second bandwidths, and configures the UE (14, 200) according to the determined SRS configuration to control SRS transmissions by the UE (14, 200).

摘要： An inventive UE carrier aggregation (CA) capability reporting signalling model allows UEs (30) aggregating large numbers of component carriers to transmit CA-relevant capabilities to the network more efficiently than the current (legacy) signalling model. Rather than reporting CA/MIMO/CSI/NAICS capabilities separately for each supported band combination, including fallback configurations, embodiments of the present invention either report UE Radio Frequency (RF) and Baseband (BB) related capabilities separately, or report them disassociated from CA band configurations. This approach avoids the need to signal the full UE (30) set of capabilities for each of (possibly many) supported band combinations. Furthermore, fallback capabilities are signalled implicitly, eliminating the need to transmit this data.

摘要： A method and network node for controlling power of uplink transmissions from a user node when switching between a first operating mode and a second operating mode. The network node signals to the user node a first value of a maximum allowed transmit power to be applied when operating in the first operating mode and a second value of the maximum allowed transmit power to be applied when operating in the second operating mode. The user node then uses a transmit power not exceeding the first value when transmitting radio signals in the first operating mode, and uses a transmit power not exceeding the second value when transmitting radio signals in the second operating mode. The user node itself thereby regulates the transmit power depending on opera mode without requiring further signalling from the network node.

摘要： Methods and arrangements are presented wherein a user equipment (UE) supporting a first frequency band HB is enabled to communicate with a network utilizing a second frequency band. The second frequency band is a sub-band of the first frequency band or overlaps with the first frequency band. The UE, which supports the first frequency band, implements the channel numbering scheme of the second frequency band SB which overlaps with the first frequency band HB. This enables the UE supporting the first frequency band HB to recognize the second frequency band SB and communicate with the network when the UE is camped or connected to a cell operating in the second frequency band SB.

摘要： According to some embodiments, a method for use in a user equipment (UE) operable to transmit a sounding reference signal (SRS) on a plurality of carriers comprises: obtaining an indication to perform SRS carrier-based switching for a carrier; adapting a parameter for uplink transmit power control in response to the obtained indication; and transmitting an uplink signal using the adapted parameter while meeting at least one predetermined uplink power control requirement. According to some embodiments, a method for use in a network node operable to receive a SRS on a plurality of carriers comprises: sending, to a UE, an indication to perform SRS carrier-based switching for a carrier; and receiving, from the UE, an uplink signal based on the parameter for uplink transmit power control adapted in response to the sent indication, wherein the uplink signal meets at least one uplink power control requirement.
