A method used in a BS for scheduling a UE, and an associated BS is disclosed. The method includes: allocating one or more DL Resource Blocks (RBs) for transmitting DownLink (DL) data to the UE (S); determining an UpLink (UL) control channel position for the UE transmitting a Hybrid Automatic Repeat Request (HARQ) feedback of the DL data, based on the allocated one or more DL RBs (S); and transmitting the DL data to the UE by using the allocated one or more DL RBs (S). Said method also related to a method used in a UE for transmitting a HARQ feedback, and an associated UE.

One embodiment of the present disclosure relates to a method for uplink SPS release. The method for operating a network node device comprises: determining whether or not there is a dynamically scheduled uplink transmission for a communication device in an uplink sub-frame where the communication device needs to perform an uplink SPS release; sending to the communication device, in response to determining that there is a dynamically scheduled uplink transmission for the communication device in the uplink sub-frame where the communication device needs to perform an uplink SPS release, a dynamic scheduling DCI message for the dynamically scheduled uplink transmission. At least one field of the dynamic scheduling DCI message is configured in a manner that the dynamic scheduling DCI implicitly indicates the uplink SPS release. The method further comprises sending to the communication device, in response to determining that there is no dynamically scheduled uplink transmission for the communication device in the uplink sub-frame where the communication device needs to perform an uplink SPS release, an uplink SPS release DCI message to explicitly indicate the uplink SPS release. According to an aspect of the present disclosure, there are provided corresponding methods and devices.

The present disclosure relates to a method used in a BS for transmitting control information to a UE, and an associated BS. The method includes: generating a first indication indicating whether data, which are downlink data transmitted from the BS to the UE or uplink data transmitted from the UE to the BS, are in an initial transmission or a retransmission, the first indication being comprised in the control information; if the data are in the initial transmission, generating a second indication for determining modulation mode and Transport Block, TB, size of the data, the second indication being comprised in the control information; and transmitting the control information to the UE.

Methods and apparatuses for uplink resource allocation have been disclosed. The method comprises: determining a frequency position of physical random access channel (PRACH) in a frequency region for physical uplink control channel (PUCCH); and determining a frequency position of the PUCCH based on a logic-to-physical mapping rule. The logic-to-physical mapping rule takes the frequency position of the PRACH as a parameter. According to the proposed solution, the PUSCH resource can be kept continuous and the flexibility of PRACH configuration can be maintained.
