Description

Wireless resource configuration method and device

technical field

The present invention relates to the communication field, in particular, to a radio resource configuration method and device.

Background technique

In the discussion of 3GPP wireless technology, the requirement of scheduling-free uplink transmission is proposed, that is, the network pre-allocates dedicated or shared semi-static uplink wireless resources for UEs, and UEs do not need to request the network in advance when sending uplink data. By allocating an uplink grant (UL grant), the pre-semi-statically allocated uplink radio resources can be directly used for uplink data transmission.

A method for realizing the above-mentioned scheduling-free transmission is to allocate the semi-static radio resources in a method similar to the semi-persistent scheduling (semistatic scheduling like, SPS-like for short) method in the prior art of 3GPP.

In the existing SPS technology, the network element of the access network (such as eNB in LTE, gNB in 5G/NR) configures the SPS interval for the user terminal (UE) through a radio resource control (Radio Resource Control, referred to as RRC) message (interval), and the SPS C-RNTI for the SPS configuration command (SPS command).

The network element of the access network sends downlink control information (Downlink Control Information, DCI) scrambled with SPS C-RNTI on the physical downlink control channel (Physical Downlink Control Channel, PDCCH for short), which is used to control the activation and deactivation of SPS scheduling. Activation, Hybrid Automatic RepeatreQuest (HARQ for short) retransmission (retransmission), and configuration of modulation and coding scheme (Modulation and Coding Scheme, MCS for short) in SPS uplink authorization, frequency domain information of SPS uplink authorization, etc. wait.

In the prior art (refer to 3GPP TS36.321), if the cell NDI (new data indicator) in the DCI scrambled by the above SPS C-RNTI is set to 0, and the cell release in the DCI is set to 0, the UE initializes Or re-initialize the SPS scheduling resource, the SPS scheduling resource is: the uplink grant (UL grant) indicated by the DCI that is repeatedly configured with the SPS interval SPS interval as the cycle, the uplink SPS shown in Figure 1 is an example, the uplink grant resource is SPS interval Occurrences that repeat periodically. This process is called the SPS activation (Activation) process. The SPS uplink radio resource of the UE is also called a configured uplink grant (configured uplink grant), and the SPS downlink radio resource of the UE is also called a configured downlink assignment (configured downlink assignment).

If the cell release in the DCI is set to 1, the UE releases the configured SPS resources. For the uplink, the UE releases the configured uplink grant. For the downlink, the UE releases the configured downlink assignment. This process is called deactivation Process (deactivation).

The SPS in the prior art is used to allocate dedicated semi-static uplink or downlink radio resources for UEs. When multiple UEs share semi-statically configured uplink or downlink radio resources, how to configure uplink or downlink radio resources for each UE, And how to perform radio resource configuration operations such as activation, deactivation, and reconfiguration for each UE and for all UEs that share the same uplink or downlink radio resources is a problem that needs to be solved.

Optionally, if the wireless resource is a downlink resource, its reconfiguration implementation method is similar to the above-mentioned reconfiguration method for uplink resources.

As a specific implementation of the present invention, the above-mentioned scheduling-free wireless resources are configured through the SPS mechanism in 3GPP technology, and the network element of the access network configures the UE to use the scheduling-free wireless resources by configuring SPS configuration for the UE, specifically:

The SPS interval (SPS interval) is configured for the UE, and the same or different SPS intervals can be configured for the UEs sharing the scheduling-free radio resources.

Configure the same or different numbers of HARQ processes using SPS resources for the UEs that share the scheduling-free radio resources.

Configure a UE-specific RNTI, SPS C-RNTI, for each UE that shares and uses scheduling-free radio resources;

And UEs sharing the same scheduling-free radio resource are configured with the same common RNTI, Common SPS C-RNTI.

The access network element can configure one or more SPS configurations for a UE, so that the UE uses multiple sets of scheduling-free radio resources. As shown in Figure 7, the UE is configured with two sets of SPS configurations, and the UE uses each set of SPS configuration radio resources. The configured uplink authorization is shown in Figure 7.

The network element of the access network configures the UE-specific RNTI for each set of SPS configuration and the public RNTI specific to the SPS configuration for the UE. At this time, in the present invention, the configured uplink grant is the uplink grant using a configured set of SPS configuration uplink wireless resources, and the configured downlink grant in the present invention is the configured downlink grant using a configured set of SPS configuration. Downlink assignment of radio resources.

Through the method provided by the present invention, the functions of flexibly allocating, activating, deactivating and reconfiguring the shared scheduling-free wireless resources for UEs that use the scheduling-free wireless resources are realized.

When the access network controls a specific UE to use the shared scheduling-free radio resource, it can control the behavior of the UE to use the radio resource through the UE-specific RNTI scrambled DCI.
