To relieve signaling congestion, UEs (30) having delay-tolerant data are moved more rapidly to the non UL synchronized state, freeing up PUCCH resources for users that have not indicated a delay-tolerance. In one embodiment, a resource conservative mode is defined for a UE (30) having delay-tolerant data (e.g., from a “background” app); otherwise, the UE (30) assumes a default mode. In one embodiment, the network sends the UE a pair of first and a second values (or indices to them) for a Time Alignment Timer, TAT (56, 66) in the UE (30).

In the default mode, the UE (30) retains PUCCH and has low latency for scheduling requests. The network may preconfigure the pair of TAT values.

Techniques of performing binaural rendering involve separating symmetric and antisymmetric terms in the total output rendered in the ears of a listener. Along these lines, a sound field includes a set of sound field weights corresponding to spherical harmonic (SH) functions in a SH expansion of the sound field. In addition, an aggregate head-related transfer function (HRTF) includes a set of HRTF weights that correspond to a SH function. An HRTF weight may be generated from aggregating products of an HRTF at each of a set of loudspeaker positions and a SH function to which the HRTF weight corresponds at that loudspeaker position.

One may save much computation by grouping the products into symmetric terms and antisymmetric terms. The rendered sound field in, say, the left ear is the sum over each loudspeaker position of the sum of the symmetric terms and antisymmetric terms for that loudspeaker position. Accordingly, because the head of the listener is assumed symmetric about the forward axis, the rendered sound field in the right ear is the sum over each loudspeaker position of the difference between the symmetric terms and antisymmetric terms for that loudspeaker position.
