Abstract
A low complexity user equipment (40) includes maximum size restriction, such as a maximum transport block size, for simultaneous downlink transmissions. When the user equipment (40) receives simultaneous downlink transmission exceeding the maximum size restriction, the user equipment (40) is allowed to skip decoding of one or more of the downlink transmission (e.g.,one or more transport blocks) according to a predetermined set of rules.

A method implemented in a user equipment of receiving simultaneous downlink transmissions, the method comprising:
- receiving scheduling information for a set of simultaneous downlink transmissions, said scheduling information comprising a transport block size for each downlink transmission in said set of simultaneous downlink transmissions;
- determining whether a total transport block size of the downlink transmissions in the set exceeds a total transport block size threshold;
- and
- in response to determining that the total transport block size of the downlink transmissions in the set exceeds the total transport block size threshold, decoding a subset of transport blocks in the set of downlink transmissions selected according to a set of rules.
A user equipment in a wireless communication network, the user equipment comprising:
- transceiver circuits configured to communicate with one or more radio base stations in the wireless communication network;
- a processing circuit operatively connected to the transceiver circuits and configured to:
- receive scheduling information for a set of simultaneous downlink transmissions, said scheduling information comprising a transport block size for each downlink transmission in the set of simultaneous downlink transmissions;
- determine whether the total transport block size of the downlink transmissions in the set exceeds a total transport block size threshold;
- and
- decode a subset of the transport blocks in the set of downlink transmissions selected according to a set of rules, in response to determining that the total transport block size of the transport blocks in the set of downlink transmissions exceeds the total transport block size threshold.
A method implemented in a radio base station of transmitting simultaneous downlink transmissions to a user equipment, the method comprising:
- determining whether a total transport block size restriction for simultaneous downlink transmissions applies to the user equipment;
- and
- in response to determining that the total transport block size restriction applies, scheduling a set of simultaneous downlink transmissions selected based on a set of rules to avoid exceeding the total transport block size restriction.
A radio base station in a wireless communication network, the radio base station comprising:
- transceiver circuits configured to communicate with one or more user equipment in the wireless communication network;
- a processing circuit operatively connected to the transceiver circuits and configured to:
- determine whether a total transport block size restriction for simultaneous downlink transmissions applies to the user equipment;
- and
- schedule a set of simultaneous downlink transmissions selected based on a set of rules to avoid exceeding the total transport block size restriction, in response to determining that the total transport block size restriction applies.
