摘要:
Certain aspects of the present disclosure propose techniques for avoiding a disruption in synchronous hybrid automatic repeat request operation at system time rollover. The techniques define the behavior of a system before and after the system frame number (SFN) rollover point to ensure a known relationship between a hybrid automatic repeat request (HARQ) process identification number and system time.

Techniques are provided for synchronized radio link control (RLC) and/or media access control (MAC). For example, there is provided a method that involves generating an RLC protocol data unit (PDU) according to a segmentation protocol for maximizing RLC PDU size while allowing the RLC PDU to fit into a defined MAC transport block, the RLC PDU comprising at least one RLC service data unit (SDU) or RLC SDU segment. The method may involve determining a PDU data size for each given RLC SDU. The method may further involve (a) attaching a given RLC SDU to the RLC PDU and (b) delivering the RLC PDU to a lower layer, in response to a SDU data size for the given RLC SDU exceeding a defined size limit.

Methods and apparatuses are provided that include decoding multicast broadcast communications where scheduling information related to a multicast channel is not properly received over a control channel. Media access control (MAC) packets can be decoded to determine whether a MAC subheader indicates the packet relates to a logical channel by indicating an associated channel identifier. Where the channel identifier of the MAC packet matches that of a requested logical channel, data in the MAC packet can be provided to a communications layer. Subsequent packets can be processed and provided to the communications layer until a different channel identifier is encountered.

A method for mitigation of lost resource allocation synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a Hybrid Automatic Repeat Request (HARQ) transmission and/or retransmission process is described. The method includes determining whether resource allocation is out of synchronization between a user equipment (UE) and an evolved Node B (eNodeB) during a hybrid automatic repeat request (HARQ) transmission and/or retransmission process. The method further includes mitigating a loss of resource allocation synchronization between the UE and the eNodeB during the HARQ transmission and/or retransmission process.

摘要:
Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station.

摘要:
Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.
