Definitions

  • a method of wireless communication may include receiving a connection reconfiguration message associated with a handover from a source base station to a target base station, receiving a data transmission from the source base station after receiving the connection reconfiguration message, performing an access procedure with the target base station based at least in part on the connection reconfiguration message, and resetting a MAC configuration, resetting an RLC configuration, or reestablishing a PDCP configuration, or any combination thereof, based at least in part on a successful access procedure.
  • Some examples of the method, apparatuses, or non-transitory computer-readable medium described herein may further include processes, features, means, or instructions for receiving a subsequent data transmission from the target base station based at least in part on the reset MAC configuration, the reset RLC configuration, the reestablished PDCP configuration, or any combination thereof. Additionally or alternatively, in some examples the data transmission and the subsequent data transmission use a same RLC/PDCP stack.
  • a non-transitory computer-readable medium storing code for wireless communication is described.
  • the code may include instructions executable to receive an indication of a dual link handover capability from a wireless device, determine that a target base station does not support dual link handover, and refrain from transmission of a connection reconfiguration message associated with a handover of the wireless device to the target base station, based at least in part on the determination.
  • a UE 115 may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a wireless local loop (WLL) station, or the like.
  • the UEs 115 may communicate with base stations 105, and may support dual link handover.
  • a UE 115 may determine that a radio link has failed by performing radio link monitoring (RLM) measurements. If a link fails, the UE 115 may initiate a radio link failure (RLF) procedure. For example, an RLF procedure may be triggered upon an RLC indication that a maximum number of retransmissions has been reached, upon receiving a maximum number of RLM out-of-sync indications, or upon radio failure during a RACH procedure. In some cases (e.g., after reaching the limit for out-of-sync indications) a UE 115 may initiate a timer and wait to determine whether a threshold number of in-sync indications are received.
  • RLM radio link monitoring
  • the base station dual link handover module 810 may determine that the target base station does not support dual link handover. For example, the source base station dual link handover module 810 may receive an indication of the capabilities of the target base station, which may indicate that the target base station does not have dual link handover capability. The base station dual link handover module 810 may refrain transmission of the connection reconfiguration message associated with a handover of the wireless device to the target base station, based on the determination. [0096]
  • the transmitter 815 may transmit signals received from other components of wireless device 800. In some examples, the transmitter 815 may be collocated with the receiver 805 in a transceiver module. The transmitter 815 may include a single antenna, or it may include a plurality of antennas.
  • FIG. 10 shows a block diagram 1000 of a base station dual link handover module 810-b which may be a component of a wireless device 800 or a wireless device 900 that supports dual link handover in accordance with various aspects of the present disclosure.
  • the base station dual link handover module 810-b may be an example of aspects of a base station dual link handover module 810 described with reference to FIGs. 8-9.
  • the base station dual link handover module 810-b may include a BS connection reconfiguration module 905-a, a BS data module 910-a, a handover execution module 915-a, a handover prepare module 920- a, and a BS access module 925-a. Each of these modules may perform the functions described herein and with reference to FIG. 9.
  • the base station dual link handover module 810-b may also include a BS dual link capability module 1005, and a bearer transfer module 1010.
  • the bearer transfer module 1010 may receive an SN status transfer message or a bearer data message from the source base station in response to the handover execution message as described herein and with reference to FIGs. 2-3.
  • wireless device 400 wireless device 500, dual link handover module 410, system 700, wireless device 800, wireless device 900, base station dual link handover module 810-b, and system 1100 may, individually or collectively, be implemented with at least one ASIC adapted to perform some or all of the applicable functions in hardware.
  • the functions may be performed by one or more other processing units (or cores), on at least one IC.
  • other types of integrated circuits may be used (e.g., Structured/Platform ASICs, an FPGA, or another semi-custom IC), which may be programmed in any manner known in the art.
  • 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new releases of Universal Mobile Telecommunications System (UMTS) that use E-UTRA.
  • UTRA, E-UTRA, UMTS, LTE, LTE-A, and Global System for Mobile communications (GSM) are described in documents from an organization named "3rd Generation Partnership Project” (3 GPP).
  • CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2).
  • the techniques described herein may be used for the systems and radio technologies mentioned above as well as other systems and radio technologies.
  • Each communication link described herein including, for example, wireless communications systems 100 and 200 of FIGs. 1 and 2— may include one or more carriers, where each carrier may be a signal made up of multiple sub-carriers (e.g., waveform signals of different frequencies). Each modulated signal may be sent on a different sub-carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, user data, etc.
  • the communication links described herein e.g., communication links 125 of FIG.
