摘要:
A network node (100) serves a cell (10) of a mobile network. The network node indicates an offset value to a user equipment (50-1) in the cell (10). The offset value is added to a channel quality value measured by the user equipment (50-1) for triggering a handover from the cell (10) to a further cell (10') of the mobile network. The network node (100) increases the indicated offset value until a handover of the user equipment (50-1) to the further cell (10') of the mobile network is triggered. After the handover to the further cell (10'), the network node (100) receives an indication of a channel quality of a downlink control channel of the further cell as experienced by the user equipment (50-1), e.g., in control signalling of a further handover of the user equipment (50-1) back to the cell (10) or in a request to protect radio resources of the downlink control channel.

1. A method for communicating a plurality of data packets to a receiver in a radio communication system, comprising the steps of transmitting the data packets to the receiver, evaluating the transmission quality, comparing the evaluated transmission quality with at least two thresholds, choosing a transmission mode in dependence of the result of the preceding comparison step is disclosed wherein:
a) a first transmission mode is chosen when the evaluated transmission quality is below a first threshold, whereby in said first transmission mode the data packets are transmitted via a single radio link b) a second transmission mode is chosen when the transmission quality is above a second threshold whereby in said second transmission mode the data packets are transmitted one time via a first radio link and a second time via an additional radio link c) a third transmission mode is chosen when the evaluated transmission quality lies in-between said first and said second threshold whereby in said third transmission mode data packets are transmitted one time via a first radio link and a fraction of the data packets is transmitted a second time via an additional radio link.

The example method further includes, in the same wireless device, receiving and processing first Layer 2 data on a first physical data channel and receiving and processing second Layer 2 data on a second physical data channel, wherein the receiving and processing of the first Layer 2 data comprises the use of soft HARQ combining and wherein the receiving and processing of the second Layer 2 data comprises no soft HARQ combining. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

A fifth-generation wireless communications network includes a server node, radio network equipment and a wireless device. In an example method, a server node receives first user data in response to (i) the wireless device receiving from the radio network equipment information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; (ii) the wireless device receiving an uplink access configuration index; (iii) the wireless device using the uplink access configuration index to identify an uplink access configuration from among the indicated plurality of uplink access configurations, and (iv) the wireless device transmitting the first user data to the wireless communications network according to the identified uplink access configuration. In the example method, further, the server node initiates transmission of second and third user data. This causes the wireless device to (v) receive from the radio network equipment, in a first downlink subframe, a first OFDM transmission formatted according to a first numerology and carrying the second user data, and (vi) receive from the radio network equipment, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology and carrying the third user data, wherein the numerologies have different subcarrier spacings.

Methods performed by a wireless device, such as a user equipment, operating in a dormant mode comprise performing a measurement on each of a plurality of resources from a predetermined set of resources or demodulating and decoding information from each of a plurality of resources from a predetermined set of resources, such as a set of beams. The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met. The method further comprises receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.
