Establishment of integrated links comprising integrated wireless backhaul communications links and access communications links is facilitated by transmitting multiplexed sync signals to enable synchronization between the relay transmission point devices, and using a random access channel procedure to complete the establishment. The integrated wireless backhaul communications links and access communications links can be maintained by measuring channel characteristics of the backhaul communications links using a measurement reference signal.

Systems, methods, and/or devices are used to implement variable bit encoding to improve device endurance and extend life of storage devices. In some embodiments, the method includes detecting a trigger condition with respect to one or more non-volatile memory portions (e.g., portions configured to store data encoded in a first encoding format) of a plurality of non-volatile memory portions of a storage device. In accordance with detecting the trigger condition, the method includes: determining a current and an estimated endurance metric for the plurality of non-volatile memory portions (e.g., corresponding to estimated endurance after reconfiguration of the one or more portions to store data encoded in a second encoding format), and in accordance with a determination that reconfiguration criteria are satisfied (e.g., the estimated endurance metric comprises an improvement over the current endurance metric), reconfiguring the one or more portions to store data encoded in the second encoding format.

Methods of performing link adaptation in a wireless communication system for simultaneous transmission of codewords include selecting initial modulation and coding scheme (MCS) levels for the codewords, estimating a size ratio of the codewords, determining a number of scheduling blocks (SB) for the codewords with the initial MCS levels, and determining revised MCS levels for the codewords in response to the determined number of SBs. Transport block sizes are computed for the codewords, and it is determined if there is a need to increase the number of scheduling blocks in at least one of the codewords. If there is a need to increase the number of scheduling blocks in a codeword, scheduling blocks are added to the codeword, and the transport block size for the codeword is recomputed. The codewords are then simultaneously transmitted over different multiple input-multiple output (MIMO) communication channels using the same time and frequency resources.

A radio resource management method is provided. Data for transmission is stored. The stored data is associated with user equipment (UE). A channel quality is estimated. A first modulation and coding scheme (MCS) is determined based at least in part on the estimated channel quality. A first number of scheduling blocks (SBs) required to transmit the stored data is determined based at least in part on the first MCS. The first number of SBs is a minimum of an initial number of SBs and available amount of SBs. A link quality is calculated based at least in part on a channel condition associated with the first number of SBs. A second MCS is determined based at least in part on the calculated link quality and a link quality requirement.

A method and system for determining, for a transmission time interval (TTI), an amount of resource units to be allocated to each cell served by at least one module in a wireless communication network are disclosed. The allocation is based on an estimated resource consumption of each cell, a resource limit of each cell and resource limits of the at least one module. For each TTI, a prioritized list of queues having information to be transmitted is determined, where each queue belongs to a cell of the plurality of cells. Also, for each TTI, in an order of priority of the queues, a number of resource units to be consumed by a queue is determined based at least in part on a number of resource units required to empty the queue.
