Abstract: While a transmission time interval (TTI) length of other than 1 ms is in effect for communication between mobile and network nodes, at least one timer related to discontinuous reception (DRX) is implemented according to a rule that defines a time duration of the timer different from a time duration of the same timer implemented when the TTI length is defined as 1 ms. There are a plurality of such DRX-related timers, and in certain embodiments each is associated with one rule of a set of rules for implementing the respective timer when the TTI length is other than 1 ms; and in particular examples the timers are associated with groups for this purpose and all the timers of at least one of the groups is implemented according to the same rule of the set. Thus new DRX parameters need not be sent anytime the TTI length changes.

Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for contention resolution in RACH. According to embodiments of the present disclosure, the terminal devices transmit random access requests in random access channels and the network device transmits the response to the random access requests on the downlink control channel addressed to the common identifier. According to embodiments of the present disclosure, there is one to multiple mapping for contention resolution radio network temporary identifier (CR-RNTI) and physical RACH (PRACH). In this way, the number of RNTIs is decreased and the overhead is reduced.

Abstract: Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.
