Abstract
According to an aspect, there is provided a method performed by a wireless device for performing Packet Data Convergence Protocol, PDCP, entity re-establishment. The wireless device is acting as a Packet Data Convergence Protocol, PDCP, receiving entity. The method comprises receiving (101) a request to perform PDCP entity re-establishment; responsive to the request, resetting (103) a header compression protocol by discarding any contexts associated with the header compression protocol, and refraining (105) from transmitting feedback associated with the header compression protocol to a PDCP transmitting entity.
Claims16
A method performed by a wireless device for performing Packet Data Convergence Protocol, PDCP, entity re-establishment, wherein the wireless device is acting as a Packet Data Convergence Protocol, PDCP, receiving entity, the method comprising:
- receiving a request to perform PDCP entity re-establishment;
- responsive to the request, resetting a header compression protocol by discarding any contexts associated with the header compression protocol,
- refraining from transmitting feedback associated with the header compression protocol to a PDCP transmitting entity;
- and
- resuming generation and transmission of feedback associated with the header compression protocol responsive to establishing a new context associated with the header compression protocol after completion of the PDCP entity re-establishment.
A method performed by a base station for performing Packet Data Convergence Protocol, PDCP, entity re-establishment, wherein the base station is acting as a PDCP receiving entity, the method comprising:
- receiving a request to perform PDCP entity re-establishment;
- responsive to the request, resetting a header compression protocol by discarding any contexts associated with the header compression protocol,
- refraining from transmitting feedback associated with the header compression protocol to a PDCP transmitting entity;
- and
- resuming generation and transmission of feedback associated with the header compression protocol responsive to establishing a new context associated with the header compression protocol after completion of the PDCP entity re-establishment.
A wireless device for performing Packet Data Convergence Protocol, PDCP, entity re-establishment, wherein the wireless device is acting as a Packet Data Convergence Protocol, PDCP, receiving entity, the wireless device configured to:
- receive a request to perform PDCP entity re-establishment;
- responsive to the request, reset a header compression protocol by discarding any contexts associated with the header compression protocol, and
- refrain from transmitting feedback associated with the header compression protocol to a PDCP transmitting entity;
- and
- resume generation and transmission of feedback associated with the header compression protocol responsive to establishing a new context associated with the header compression protocol after completion of the PDCP entity re-establishment.
A base station for performing Packet Data Convergence Protocol, PDCP, entity re-establishment, wherein the base station is acting as a PDCP receiving entity, the base station configured to:
- receive a request to perform PDCP entity re-establishment;
- responsive to the request, reset a header compression protocol by discarding any contexts associated with the header compression protocol,
- refrain from transmitting feedback associated with the header compression protocol to a PDCP transmitting entity;
- and
- resume transmission of feedback associated with the header compression protocol responsive to establishing a new context associated with the header compression protocol after completion of the PDCP entity re-establishment.
