The method comprises obtaining (120) a position of the wireless device, wherein the position of the wireless device is associated with an expected beam. When the serving beam and the expected beam are different from each other thereby resulting in a deviation, the method comprises determining (140) whether the deviation has occurred at least more than once. When the deviation has occurred at least more than once, the method comprises issuing (160) a notification indicating that the expected beam is at least partially obscured with respect to transmissions for the wireless device.

摘要： A RAP detection procedure that can be used to find the best narrow beam in an efficient manner. In a first step, an access point correlates an incoming signal with appropriate RAPs and then selects at least one candidate RAP for further processing in at least one set of narrow beams that all reside within the coverage area of a wide beam with which the candidate preamble is associated. For each candidate RAP, a second step is executed including narrow beamforming and a PRACH receiver chain including threshold comparison.

摘要： A method for operating a radio access system comprises configuring (S1) a first carrier and a second carrier for use for radio access in a first radio access system. The second carrier is configured for frequency division duplex signalling. A useful frequency band of the second carrier is defined to, at least partially, overlap in frequency with a useful frequency band of a third carrier of a second radio access system. At least a part of the useful frequency band of the second carrier overlaps in frequency with guard bands of the third carrier. A method for signal scheduling comprises scheduling, in a first radio access system having a first carrier with a first carrier frequency band and a second carrier with a second carrier frequency band, uplink signals in the second carrier. Network nodes for carrying out the methods are also presented.

摘要： Methods by a radio unit and related radio units are disclosed which control capacity of baseband processing resources allocated to a radio communication cell. The method includes determining a deadline margin for a prior transmission time interval (TTI) based on a difference between a time when baseband processing of data for transmission completed and a defined deadline time for completion of the baseband processing. The method further includes determining a desired capacity of baseband processing resources to allocate to the radio communication cell for a present TTI, and controlling capacity of baseband processing resources allocated to the radio communication cell for the present TTI based on the deadline margin and the desired capacity.

摘要： A method and apparatus for controlling the use of discontinuous transmission in a cellular telephone (100). The preferred embodiment of the present invention includes a voice activity detector (106) for detecting the presence or absence of speech (Step 300) and an energy detector (120) for measuring the energy level (Step 311) of sound input (Step 300) to a microphone (110) of a cellular telephone (100) during the absence of speech. The present invention also includes a comparator (150) for comparing the measured noise energy level against a threshold value (Step 330). The determination as to the presence or absence of speech and the output of the comparator are provided to a controller (140). The controller enables discontinuous transmission when the energy level detected during the absence of speech is less than or equal to the threshold value (Step 320) and disables discontinuous transmission when the measured energy level exceeds the threshold value (Step 320).

摘要： Method performed by a network node (101) for reducing interference in neighboring cells. The network node (101) operates in a communication network (100), which is adapted to wirelessly serve a UE (120) via a serving Radio Access, RA, node (110). The network node obtains a determination of at least one of Reference Signal Received Power, RSRP, and Reference Signal Received Quality, RSRQ, from the serving RA node (110) as received by the UE (120) and a determination of at least one of RSRP and RSRQ from a neighboring RA node (111) as received by the UE (120), when the UE (120) is connected to the serving RA node (110).The network node (101) further decides to reduce a transmit power of the serving RA node (110) serving the connected UE (120), when the determined RSRP and/or RSRQ of the serving RA node (110) is higher than the RSRP and/or RSRQ of the neighboring RA node (111), in order to reduce the interference in neighboring cells caused by the serving RA node (110).
