Abstract: Various communication systems may benefit from allocation of candidates for a channel. For example, some new radio communication systems may benefit from hashing for allocation of control channel candidates. A method can include applying a hashing function for associating a plurality of decoding candidates of a search space set with subsets of control channel elements of a control resource set, and using the decoding candidate for scheduling of a user equipment in a control channel, wherein the hashing function is non-uniform in a pseudo-random manner and with one candidate per subband. The method can also include scheduling the user equipment based on the applied hashing function.

Abstract: Various communication systems may benefit from the appropriate communication of acknowledgements. For example, various communication systems, such as New Radio, may benefit from a scalable codebook size definition in a scenario with dynamically varying acknowledgement timing. A method can include receiving a timing offset value in a downlink grant (910). The method can also include determining a first downlink time slot within a feedback window based on the timing offset value (920).

Abstract: Various communication systems may benefit from efficient communications. For example, low latency long term evolution (LTE) systems may benefit from a short physical uplink shared channel (PUSCH) arrangement. A method may include operating a user equipment to follow a shortened transmission time interval. The shortened transmission time interval can be an integer number, L, of symbols in length. The method can also include sending a demodulation reference signal in at least a first symbol of the L symbols of the shortened transmission time interval.

Abstract: This document discloses a solution for scheduling communication resources. According to an aspect, a method comprises: storing, in a memory, a mapping database defining translation specifications between a first resource space and a second resource space, wherein the first resource space is based on at least a first sub-carrier spacing and the second resource space is based on at least a second sub-carrier spacing different from the first sub-carrier spacing; receiving, from a second network node of the wireless network, a scheduling message defining communication resources in the first resource space; translating the communication resources of the first resource space into communication resources of the second resource space by using the mapping database; and communicating a message with the second network node in the communication resources of the second resource space.

Abstract: A technique may include determining, by a base station in a wireless network, that the base station was unable to transmit a synchronization signal block for a beam via a beam-specific synchronization signal block position that is associated with the beam; transmitting, by the base station in response to the determining, a synchronization signal block for the beam via a non-beam-specific synchronization signal block position; and transmitting, by the base station, control information indicating the transmitting of the synchronization signal block via the non-beam-specific synchronization signal block position.
