| 摘要 |
This disclosure relates to a method (100) performed by a network node supporting the use of a single Physical Uplink Control Channel, PUCCH, resource to a plurality of communication devices such that the plurality of communication devices can share the single PUCCH resource. Different transmission masks are assigned (110) to different communication devices, each transmission mask indicating re- occurring transmission occasions at which each communication device is either allowed or disallowed to transmit Scheduling Requests, SRs, to the network node, whereby a different SR periodicity pattern is defined for each one of the plurality communication devices. When a burst of Scheduling Requests, SRs, is received (130) from a communication device, the communication device can be identified (140) by recognition of the SR periodicity pattern of the received burst of SRs. Also, an uplink grant may be transmitted (150) to the thus identified communication device. |
