Abstract
Embodiments of the present disclosure relates to estimating downlink size for a multicast traffic. According to embodiments of the present disclosure, a first device receives downlink control information (DCI) for a multicast traffic. The first device determines field size(s) in the DCI based on one or more parameters which are associated with the field size estimation for the multicast traffic. The first device decodes the DCI based on the determined field sizes(s). In this way, the DCI can be blindly decoded correctly.
Claims12
A first device, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to:
- receive, from a second device, a radio resource control configuration for multicast traffic, wherein the radio resource control configuration comprises a set of parameters associated with a field size estimation of a downlink control information for multicast traffic;
- receive, from the second device, the downlink control information for multicast traffic;
- determine, at the first device, a format of the downlink control information;
- determine, at the first device, whether a common frequency resource is configured, based on a determining that the format of the downlink control information is not a preconfigured format;
- determine, at the first device, a frequency domain resource allocation field size based on an active bandwidth part size, in response to the determining that the common frequency resource is not configured;
- determine, at the first device, one or more field sizes of fields in the downlink control information based on the set of parameters;
- and
- decode the downlink control information based on the determined one or more field sizes, wherein the set of parameters comprises at least one of:
- a carrier indicator field parameter which indicates a size of a carrier indicator field in the downlink control information;
- a feedback timing indicator parameter which indicates a size of a feedback timing indicator field in the downlink control information;
- a priority indicator field parameter which indicates a size of a priority indicator field in the downlink control information;
- or
- a parameter for an optional configuration which indicates a field size of the optional configuration in the downlink control information.

- determining, at the first device, one or more field sizes of fields in the downlink control information based on the set of parameters;
- and
- decoding the downlink control information based on the determined one or more field sizes, wherein the set of parameters comprises at least one of:
- a carrier indicator field parameter which indicates a size of a carrier indicator field in the downlink control information;
- a feedback timing indicator parameter which indicates a size of a feedback timing indicator field in the downlink control information;
- a priority indicator field parameter which indicates a size of a priority indicator field in the downlink control information;
- or
- a parameter for an optional configuration which indicates a field size of the optional configuration in the downlink control information.
