Description

Method, equipment and system for configuring random access channel opportunity allocation

Technical Field

The present disclosure relates generally to wireless communications. In particular, the present disclosure relates to methods, devices and systems for configuring random access channel (Random Access Channel, RACH) occasion assignments.

Background

Wireless communication technology is pushing the world to an increasingly interconnected and networked society. High-speed and low-latency wireless communications rely on efficient network resource management and allocation between user equipment and radio access network nodes (including but not limited to base stations). New generation networks are expected to provide high speed, low latency, and ultra-reliable communication capabilities, and to meet demands from different industries and users.

For the fifth generation mobile communication technology, the base station and/or the user equipment needs to configure signal resources for a physical random access channel (Physical Random Access Channel, PRACH). Existing systems for configuring signal resources for PRACH have several problems/challenges. For example, for wider channel bandwidths in high carrier frequencies, some problems/challenges are associated with new subcarrier spacings (Subcarrier Spacing, SCS); another problem/challenge is how the user equipment (or base station) can confirm the slot number or subframe number of the PRACH slot(s) in a particular subcarrier interval if a new subcarrier interval is introduced.

The present disclosure describes various embodiments for configuring Random Access Channel (RACH) occasion assignments that address at least some of the problems/challenges associated with existing systems to improve performance of wireless communications.

The present disclosure describes methods and apparatus for configuring Random Access Channel (RACH) occasion assignments.

New Generation (NG) mobile communication systems are pushing the world to an increasingly interconnected and networked society. High-speed and low-latency wireless communications rely on efficient network resource management and allocation between user equipment and radio access network nodes, including but not limited to radio base stations. New generation networks are expected to provide high speed, low latency, and ultra-reliable communication capabilities, and to meet demands from different industries and users.

The present disclosure describes various embodiments for transmitting initial access information to a user equipment. Fig. 1 illustrates a wireless communication system 100 including a radio network node 118 and one or more User Equipment (UE) 110. The radio network node may comprise a network base station, which may be a node B (NodeB, NB, e.g. gcb) in a mobile communication environment. Each UE may communicate wirelessly with a wireless network node via one or more radio channels 115. For example, the first UE 110 may wirelessly communicate with the wireless network node 118 via a channel comprising a plurality of radio channels during a particular time period. The network base station 118 may configure PRACH transmission parameters for the UE 110. UE 110 may receive Physical Random Access Channel (PRACH) transmission parameters (e.g., without limitation, PRACH preamble format, time resources, and frequency resources of PRACH transmission).

For the fifth generation mobile communication technology, the base station and/or the user equipment needs to configure signal resources for a Physical Random Access Channel (PRACH). Existing systems for configuring signal resources for PRACH have several problems/challenges. For example, for wider channel bandwidths in high carrier frequencies, some problems/challenges are associated with new subcarrier spacing (SCS); another problem/challenge is how a user equipment (or base station) can map one or more slot numbers or one or more subframe numbers of PRACH slot(s) in a particular subcarrier interval. Another problem/challenge is how a user equipment (or base station) can confirm or configure the slot number or subframe number of PRACH slot(s) in a particular subcarrier interval. The present disclosure may address at least some of the problems/challenges associated with existing systems to improve the performance of wireless communications.

For 5G NR, in a first frequency range (First Frequency Range, FR 1) there may be a parameter specifying one or more subframe numbers to ensure that the UE can acknowledge one or more subframe numbers of the PRACH occasion in the time domain. In the frequency range (FR 2), there may be a parameter specifying one or more slot numbers to ensure that the UE is able to acknowledge one or more slot numbers of the PRACH occasion in the time domain. Rules for configuring/mapping one or more subframe numbers or one or more slot numbers of the PRACH may be described in the present disclosure when introducing a new PRACH subcarrier spacing.

In various embodiments, the parameters may be used to specify one or more subframe numbers. For example, in the random access configuration of FR 1 and unpaired spectrum, there may be one or more subframe numbers in a frame for one PRACH configuration index. The one or more subframe numbers may be one or more integers between 0 and 9 (including 0 and 9).

In various embodiments, parameters may be used to specify one or more slot numbers. For example, in the random access configuration of FR 2 and unpaired spectrum, there may be one or more slot numbers for one PRACH configuration index. The one or more slot numbers correspond to slots in a frame of a 60kHz subcarrier spacing. The one or more slot numbers may be one or more integers between 0 and 39 (including 0 and 39).

In various embodiments, one or more new PRACH subcarrier spacings may be introduced and parameters may be used to ensure that one or more slot numbers or subframe numbers of PRACH slot(s) in a particular subcarrier spacing are acknowledged by the UE and/or base station. For example, the parameter may be a mode parameter of a position mode including Q positions for a specific duration. In one embodiment, the carrier frequency in each embodiment may be any part or all of the frequency range of the first frequency range (FR 1) and/or the second frequency range (FR 2). In another implementation, the carrier frequency in various embodiments may be a third frequency range (FR 3), such as, but not limited to, a higher frequency band above FR 2, such as 52.6GHz to 71GHz.
