Abstract
A wireless device receives one or more messages. The one or more messages may comprise a first RNTI for a first SPS and a second for a second SPS. A downlink control information (DCI) corresponding to one of the first RNTI or the second RNTI may be received. The DCI may be validated, at least based on a cyclic shift value associated with the DCI, if the DCI corresponds to the first RNTI. Otherwise, the DCI may be validated without considering the cyclic shift value. One of the first SPS or the second SPS, corresponding to the DCI, may be activated in response to the validating being successful.
Claims33
A method comprising:
- receiving, by a wireless device, first downlink control information (DCI) corresponding to a first radio network temporary identifier (RNTI) for first semi-persistent scheduling (SPS) resources;
- receiving second DCI corresponding to a second RNTI for second SPS resources;
- validating, at least based on a first cyclic shift value associated with the first SPS resources, the first DCI;
- validating, without considering a second cyclic shift value associated with the second SPS resources, the second DCI;
- based on successful validation of the first DCI, activating or deactivating the first SPS resources;
- and
- based on successful validation of the second DCI, activating or deactivating the second SPS resources.
An apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- receive first downlink control information (DCI) corresponding to a first radio network temporary identifier (RNTI) for first semi-persistent scheduling (SPS) resources;
- receive second DCI corresponding to a second RNTI for second SPS resources;
- validate, at least based on a first cyclic shift value associated with the first SPS resources, the first DCI;
- validate, without considering a second cyclic shift value associated with the second SPS resources, the second DCI;
- based on successful validation of the first DCI, activate or deactivate the first SPS resources;
- and
- based on successful validation of the second DCI, activate or deactivate the second SPS resources.
A system comprising:
- a wireless device and a base station,
- wherein the base station is configured to:
- send, to the wireless device, first downlink control information (DCI) corresponding to a first radio network temporary identifier (RNTI) for first semi-persistent scheduling (SPS) resources;
- and
- send, to the wireless device, second DCI corresponding to a second RNTI for second SPS resources, and
- wherein the wireless device is configured to:
- validate, at least based on a first cyclic shift value associated with the first SPS resources, the first DCI;
- validate, without considering a second cyclic shift value associated with the second SPS resources, the second DCI;
- based on successful validation of the first DCI, activate or deactivate the first SPS resources;
- and
- based on successful validation of the second DCI, activate or deactivate the second SPS resources.
