摘要： Mixture of implicit and explicit signaling of the Synchronization Signal Block (SSB) time index for 5G New Radio. In NR, multiple SSBs (each containing PSS, SSS and PBCH) are sent on different beams, and on multiple time occurences. The UE when detecting the SSB has therefore to identify the SSB time instance and the beam ID used by the gNB. This detection is allowed by said SSB time index. If sent on the PBCH, this prevents soft combining between PBCH time instances. It is therefore proposed to send the SSB time index via the DMRS interleaved with the PBCH. Problem: overhead would be too high for DMRS solution only. Solution: Part of the bits (the LSBs) of the SSB time index are signaled implicitly via the relative position of PSS, SSS and PBCH within a SSB. The other bits are explicitly sent using DMRS scrambling.

摘要： A communications device is configured to receive data transmitted as encoded data packets from an infrastructure equipment of a wireless communications network. Each of the encoded data packets are transmitted as a control signal component and a data signal component. The control signal component carries control information for detecting and decoding the data signal component in which the encoded data carried by the encoded data packet is transmitted. As part of the ARQ-type protocol, at least the control signal component may be re-transmitted. By including with the control information carried by the retransmitted control signals an indication of at least a temporal location of the data signal component, which has already been transmitted and received in a buffer of a receiver, an improvement in a use of communications resource can be provided and also in some embodiments an improvement in a likelihood of correctly detecting and decoding an encoded data packet. For example if the control signal component in the first transmission was not received, then the retransmission of the control signal component can direct the receiver to the data signal component, which has already been transmitted and stored in the buffer without a requirement to retransmit the data signal component of the encoded data packet, thereby making more efficient use of the communications resources of the wireless access interface.
