Embodiment Construction

[0053] In some embodiments, the message is introduced in a Random Access Response (RAR) or with a broadcast channel, which configures the UE to transmit message 3 with OFDM or DFTS-OFDM. As an advantage, the selection between the modulation formats of Message 3 can be based on the capability of the receiver in the base station, the link budget of the individual UE and / or the affordable overhead of Message 3 .

[0054] Figure 6 is a block diagram illustrating an embodiment of network 100 in accordance with some embodiments. The network 100 includes one or more user equipments UE 110 (which may be interchangeably referred to as radios 110 ) and one or more network nodes 115 (which may be interchangeably referred to as eNBs or gNBs 115 ). UE 110 may communicate with network node 115 over a wireless interface. For example, UE 110 may transmit wireless signals to and / or receive wireless signals from one or more of network nodes 115 . The wireless signals may contain voice traff...

Abstract

A method in a network node for managing a random access procedure with respect to a plurality of wireless devices. The method includes transmitting an indication of a modulation format to one or more of a plurality of wireless devices to configure a modulation format for random access message (3) transmissions from the one or more wireless devices.

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more specifically to random access response procedures. Background technique [0002] The random access procedure is a key function in cellular systems. figure 1 The random access procedure in LTE is shown. A similar structure is expected to be used in 5G New Radio (NR). In 4G LTE, a UE that wants to access the network initiates a random access procedure on the uplink by transmitting a preamble (msg1 ) 30 on the Physical Random Access Channel (PRACH). A base station receiving this preamble and detecting a random access attempt will respond on the downlink by transmitting a random access response (Msg2) 40 on the Physical Downlink Shared Channel (PDSCH). The random access response carries an uplink scheduling grant for the UE to continue the procedure on the uplink by transmitting a follow-up message (Msg3) 50 on the physical uplink shared channel (PUSCH) for terminal identifica...
